Prognostic factors for local recurrence in patients with rectal cancer submitted to neoadjuvant chemoradiotherapy and total mesorectal excision. Clinics (Sao Paulo) 2024; 79:100464. [PMID: 39126876 PMCID: PMC11369368 DOI: 10.1016/j.clinsp.2024.100464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 06/13/2024] [Accepted: 07/14/2024] [Indexed: 08/12/2024] Open
Abstract
Prognostic factors for local recurrence in patients with rectal cancer submitted to neoadjuvant chemoradiotherapy and total mesorectal excision. BACKGROUND The standard curative treatment for locally advanced rectal cancer of the middle and lower thirds is long-course chemoradiotherapy followed by total mesorectal excision. PURPOSE To evaluate the prognostic factors associated with local recurrence in patients with rectal cancer submitted to neoadjuvant chemoradiotherapy and total mesorectal excision. METHODS Retrospective study including patients with rectal cancer T3-4N0M0 or T (any)N + M0 located within 10 cm from the anal border, or patients with T2N0M0 located within 5 cm, treated by long course chemoradiotherapy followed by total mesorectal excision with curative intent. Clinical, demographic, radiologic, surgical, and anatomopathological data were collected. Local recurrence was estimated using the Kaplan-Meier function, and risk was estimated according to each characteristic using univariate and multivariate analyses. RESULTS 270 patients were included, 57.8% male and mean age 61.7 (30‒88) years. At initial staging, 6.7% of patients were stage I, 21.5% stage II, and 71.8% stage III. Open surgery was performed in 65.2%, with sphincter preservation in 78.1%. Mortality within 30 postoperative days was 0.7%. After 49.4 (0.5‒86.1) months of median follow-up, overall and local recurrences were 26.3% and 5.9%. On multivariate analyses, local recurrence was associated with involvement of the mesorectal fascia on restaging MRI (HR = 9.11, p = 0.001) and with pathologic involvement of radial surgical margin (HR = 8.19, p < 0.001). CONCLUSION Local recurrence of rectal cancer treated with long-course chemoradiation and total mesorectal excision is low and is associated with pathologic involvement of the radial surgical margin and can be predicted on restaging MRI.

Oncologic outcomes of intersphincteric resection versus abdominoperineal resection for lower rectal cancer: a systematic review and meta-analysis. Int J Surg 2024; 110:2338-2348. [PMID: 36928167 PMCID: PMC11020000 DOI: 10.1097/js9.0000000000000205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 11/20/2022] [Indexed: 03/18/2023]
Abstract
BACKGROUND The efficacy of intersphincteric resection (ISR) surgery for patients with lower rectal cancer remains unclear compared to abdominoperineal resection (APR). The aim of this study is to compare the oncologic outcomes for lower rectal cancer patients after ISR and APR through a systematic review and meta-analysis. MATERIALS AND METHODS A systematic electronic search of the Cochrane Library, PubMed, EMBASE, and MEDLINE was performed through January 12, 2022. The primary outcomes included 5-year disease-free survival (5y-DFS) and 5-year overall survival. Secondary outcomes included circumferential resection margin involvement, local recurrence, perioperative outcomes, and other long-term outcomes. The pooled odds ratios, mean difference, or hazard ratios (HRs) of each outcome measurement and their 95% CIs were calculated. RESULTS A total of 20 nonrandomized controlled studies were included in the qualitative analysis, with 1217 patients who underwent ISR and 1135 patients who underwent APR. There was no significant difference in 5y-DFS (HR: 0.84, 95% CI: 0.55-1.29; P =0.43) and 5-year overall survival (HR: 0.93, 95% CI: 0.60-1.46; P =0.76) between the two groups. Using the results of five studies that reported matched T stage and tumor distance, we performed another pooled analysis. Compared to APR, the ISR group had equal 5y-DFS (HR: 0.76, 95% CI: 0.45-1.30; P =0.31) and 5y-LRFS (local recurrence-free survival) (HR: 0.72, 95% CI: 0.29-1.78; P =0.48). Meanwhile, ISR had equivalent local control as well as perioperative outcomes while significantly reducing the operative time (mean difference: -24.89, 95% CI: -45.21 to -4.57; P =0.02) compared to APR. CONCLUSIONS Our results show that the long-term survival and safety of patients is not affected by ISR surgery, although this result needs to be carefully considered and requires further study due to the risk of bias and limited data.

Revolutionizing sphincter preservation in ultra-low rectal cancer: exploring the potential of transanal endoscopic intersphincteric resection (taE-ISR): a propensity score-matched cohort study. Int J Surg 2024; 110:709-720. [PMID: 38016136 PMCID: PMC10871607 DOI: 10.1097/js9.0000000000000945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 11/13/2023] [Indexed: 11/30/2023]
Abstract
BACKGROUND With the optimization of neoadjuvant treatment regimens, the indications for intersphincteric resection (ISR) have expanded. However, limitations such as unclear surgical field, impaired anal function, and failure of anal preservation still exist. Transanal total mesorectal excision can complement the drawbacks of ISR. Therefore, this study combined these two techniques and proposed transanal endoscopic intersphincteric resection (taE-ISR), aiming to explore the value of this novel technique in anal preservation for ultra-low rectal cancer. MATERIAL AND METHODS Four high-volume centres were involved. After 1:1 propensity score-matching, patients with ultra-low rectal cancer underwent taE-ISR ( n =90) or ISR ( n =90) were included. Baseline characteristics, perioperative outcomes, pathological results, and follow-up were compared between the two groups. A nomogram model was established to assess the potential risks of anal preservation. RESULTS The incidence of adjacent organ injury (0.0% vs. 5.6%, P =0.059), positive distal resection margin (1.1% vs. 8.9%, P =0.034), and incomplete specimen (2.2% vs. 13.3%, P =0.012) were lower in taE-ISR group. Moreover, the anal preservation rate was significantly higher in taE-ISR group (97.8% vs. 82.2%, P =0.001). Patients in the taE-ISR group showed a better disease-free survival ( P =0.044) and lower cumulative recurrence ( P =0.022) compared to the ISR group. Surgery procedure, tumour distance, and adjacent organ injury were factors influencing anal preservation in patients with ultra-low rectal cancer. CONCLUSION taE-ISR technique was safe, feasible, and improved surgical quality, anal preservation rate and survival outcomes in ultra-low rectal cancer patients. It held significant clinical value and showed promising application prospects for anal preservation.

Abstract
Radical resection of rectal cancer is a safe and effective treatment, but there remain several complications related to anastomosis. We aimed to assess the risk factors and incidence of rectal anastomotic stenosis (AS) after rectal cancer resection. We conducted a systematic review and meta-analysis after searching PubMed, Embase, Web of Science, and Medline databases from inception until May 2023. Data are reported as the combined odds ratio (OR) for categorical variables and the weighted mean difference (WMD) for continuous variables. Six hundred and fifty-nine studies were retrieved, nine (3031 patients) of which were included in the meta-analysis. Young age (WMD = -3.09, P = 0.0002), male sex (OR = 1.53, P = 0.0002), smoking (OR = 1.54, P = 0.009), radiotherapy (OR = 2.34, P = 0.0002), protective stoma (OR = 2.88, P = 0.007), intersphincteric resection surgery (OR = 6.28, P = 0.05), anastomotic fistula (OR = 3.72, P = 0.003), and anastomotic distance (WMD = -3.11, P = 0.0006) were identified as factors that increased the risk of AS, while staple (OR = 0.39, P < 0.001) was a protective factor. The incidence of AS after rectal cancer resection was approximately 17% (95% CI: 13%-21%). We identified eight risk factors and one protective factor associated with AS after rectal cancer resection. These factors may be combined in future studies to develop a more comprehensive and accurate prediction model related to AS after rectal cancer resection.

J Gastrointest Surg 2023; 27:2526-2537. [PMID: 37848684 DOI: 10.1007/s11605-022-05565-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 12/06/2022] [Indexed: 10/19/2023]
Abstract
PURPOSE This study aimed to compare the oncological and functional outcomes following intersphincteric resection (ISR) with transverse coloplasty pouch (TCP) or straight coloanal anastomosis (SCAA) for low rectal cancer. METHODS A single-center retrospective analysis was performed on patients with low rectal cancer who received ISR between January 2016 and June 2021. The primary endpoint was to compare the outcomes of bowel function within 1 year, 1 to 2 years, and 2 years after ileostomy closure in patients undergoing two different bowel reconstruction procedures (TCP or SCAA). The postoperative complications and oncological results were also compared between the two groups. RESULTS A total of 235 patients were enrolled in this study (SCAA group: 166; TCP group: 69). There was no significant difference in complications, including grades A-C anastomotic leakage (9.6% vs 15.9%), 3-year local recurrence rates (6.1% vs 3.9%), disease-free survival (82.4%vs 83.8%), or overall survival (94.1% vs 94.7%) between the two groups. Two years after ileostomy closure, 52.7% of patients in the SCAA group were assessed as having major low anterior resection syndrome (LARS), which was significantly higher than the 25.9% of patients in the TCP group (P = 0.014), but no difference was found prior to 2 years. Similar differences were seen in Wexner scores 2 years after surgery (P = 0.032). Additionally, TCP was an independent protective factor for postoperative bowel function as measured by both the LARS (OR, 0.28; 95% CI, 0.10-0.82; p = 0.020) and Wexner scoring (OR, 0.28; 95% CI, 0.09-0.84; p = 0.023). CONCLUSION This study suggests that TCP is a safe technique that may decrease bowel dysfunction after ISR for low rectal cancer compared with SCAA 2 years after ileostomy closure.

Abstract
AIM Intersphincteric resection (ISR) is an oncologically complex operation for very low-lying rectal cancers. Yet, definition, anatomical description, operative indications and operative approaches to ISR are not standardized. The aim of this study was to standardize the definition of ISR by reaching international consensus from the experts in the field. This standardization will allow meaningful comparison in the literature in the future. METHOD A modified Delphi approach with three rounds of questionnaire was adopted. A total of 29 international experts from 11 countries were recruited for this study. Six domains with a total of 37 statements were examined, including anatomical definition; definition of intersphincteric dissection, intersphincteric resection (ISR) and ultra-low anterior resection (uLAR); indication for ISR; surgical technique of ISR; specimen description of ISR; and functional outcome assessment protocol. RESULTS Three rounds of questionnaire were performed (response rate 100%, 89.6%, 89.6%). Agreement (≥80%) reached standardization on 36 statements. CONCLUSION This study provides an international expert consensus-based definition and standardization of ISR. This is the first study standardizing terminology and definition of deep pelvis/anal canal anatomy from a surgical point of view. Intersphincteric dissection, ISR and uLAR were specifically defined for precise surgical description. Indication for ISR was determined by the rectal tumour's maximal radial infiltration (T stage) below the levator ani. A new surgical definition of T3isp was reached by consensus to define T3 low rectal tumours infiltrating the intersphincteric plane. A practical flowchart for surgical indication for uLAR/ISR/abdominoperineal resection was developed. A standardized ISR surgical technique and functional outcome assessment protocol was defined.

Abstract
AIM The incidence of benign colonic anastomotic stricture is approximately 2% in patients undergoing left hemicolectomy or anterior resection and as high as 16% in patients undergoing low anterior or intersphincteric resection. In the majority, rather than complete occlusion, a stenosis forms, which can be managed with endoscopic balloon dilatation, a self-expanding metallic stent or endoscopic electroincision. In the less common scenario of a completely occluded colonic anastomosis, surgery is often required. In this study, we aim to describe the technique we used to treat this condition non-operatively METHOD: We describe a case series of three patients with benign complete occlusion of their colorectal anastomosis and how we managed them nonoperatively with a colonic/rectal endoscopic ultrasound (EUS) anastomosis technique and a Hot lumen-apposing metallic stent. RESULTS We demonstrate that the technical and clinical success for this technique is 100%. CONCLUSIONS We believe that the technique we describe is effective and safe. It should be widely reproducible in centres with expertise in interventional EUS, given the similarity to well-established procedures such as EUS-guided gastroenterostomy. Patient selection and timing of reversal of ileostomy need careful consideration, especially in patients with a history of keloid formation. Given the shorter hospital stay and reduced invasiveness of this technique, we believe it should be considered for all patients who have complete benign occlusion of a colonic anastomosis. However, given the small number of cases and short period of follow-up, the long-term outcome of this technique is not known. More studies with higher power and a longer period of follow-up should be conducted to further ascertain the effectiveness of this technique.

Abstract
Purpose Significant improvements have been made in the surgical treatment of rectal cancer with a higher sphincter-saving rate without compromising oncologic results. There have been studies about the quality of life of rectal cancer patients after surgery. However, no study has reported the long-term annual incidence of depression after rectal cancer surgery according to stoma status. The objective of this study was to determine the annual incidence of depression after rectal cancer surgery and the factors affecting it, especially the prevalence of depression according to the presence or duration of a stoma. Methods Using the Korea National Health Insurance Service database, patients who underwent radical surgery for rectal cancer from 2002 to 2019 were searched. We analyzed the incidence and risk factors of depression in patients who underwent radical surgery for rectal cancer according to stoma status. Results Annual incidence of depression in rectal cancer patients was decreasing annually for 15 years after surgery. There was no statistically significant difference in the incidence of depression according to the stoma status. However, the diagnosis of depression within 1 year after surgery was statistically significantly increased in the permanent stoma group. Conclusion There was no difference in the overall incidence of depressive disorders among patients with rectal cancer based on their stoma status. However, a permanent stoma seems to increase the incidence in the first year after surgery. Education and intensive assessments of depressive disorders in patients with permanent stoma within 1 year after surgery are needed, particularly for female patients who are under 50 years old.

Development and validation of neoadjuvant rectal score-based signature nomograms to predict overall survival and disease-free survival in locally advanced rectal cancer: a retrospective, double center, cohort study. Int J Clin Oncol 2023; 28:268-279. [PMID: 36534264 DOI: 10.1007/s10147-022-02281-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 12/08/2022] [Indexed: 12/23/2022]
Abstract
AIM To evaluate the prognostic significance of the NAR score and develop nomograms for locally advanced rectal cancer (LARC) treated after neoadjuvant chemo-radiotherapy (nCRT) combined with total meso-rectal excision (TME) surgery to predict prognostic. METHODS Retrospective collection among LARC patients treated at Fujian Medical University Union Hospital (training cohort) and Fujian Medical University Affiliated Zhangzhou Hospital (external validation cohort) between Jan 10, 2011 and Dec 28, 2021. The NAR score was calculated by formula: [5pN-3(cT-pT) + 12]^2/9.61. NAR score low (< 8), intermediate (8-16), and high (> 16). RESULTS 1665 patients in the training cohort and 256 patients in the external validation cohorts were enrolled. Lower NAR score was significantly associated with better cumulative incidence of OS, DFS, local recurrence (LR), and distant metastasis (DM) (all P < 0.001). Multivariate Cox regression analysis indicates that NAR score, distance to the anal verge, no.253 LN metastasis, post-CRT carbohydrate antigen 19-9, tumor regression grade, and surgery method are independent predictors of OS and DFS (all P < 0.001). Among these independent factors, the NAR score had the highest area under the curve (AUC) and the nomograms to predict OS and DFS were generated. The AUCs for the accuracy of the prediction OS were 1 year = 0.742, 3 years = 0.749, 5 years = 0.713; prediction DFS were 1 year = 0.727, 3 years = 0.739, 5 years = 0.718, the models have good accuracy. CONCLUSIONS The NAR score can effectively classify patients with LARC into groups with varying outcomes of OS, DFS, LR, and DM. Moreover, the novel nomograms comprising the NAR score were developed and validated to help predict OS and DFS.

[PMID: 37750231 PMCID: PMC10521307 DOI: 10.1177/15330338231202893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 08/02/2023] [Accepted: 09/01/2023] [Indexed: 09/27/2023] Open
Abstract
Introduction: Neoadjuvant chemo-radiotherapy (nCRT) before surgery was a standard treatment strategy for locally advanced rectal cancer (LARC). The aim of this study was to assess the relationship between the predictive factors and pathological complete response (pCR) in rectal cancer patients, especially in ultra-low ones. Method: A total of 402 patients were involved in this retrospective study. The logistic regression analyses were used to compare the different subgroups in univariate analysis. Multivariate analysis was performed to determine the independent predictive factors of pCR by using a logistic regression model. Results: A total of 402 patients received preoperative CRT. In all patients, multivariate analysis revealed that circumferential tumor extent rate (CER) (≤ 2/3cycle vs >2/3 cycle, P < .001, OR = 4.834, 95% CI: 2.309-10.121), carcinoembryonic antigen (CEA) level (both ≤ 5 vs pre > 5 and post ≤ 5 vs both > 5, P = .033, OR = 1.537, 95% CI: 1.035-2.281), and interval time between the end of CRT and surgery (P = .031, OR = 2.412, 95% CI: 1.086-5.358) were predictive factors for pCR. The area under the curve (AUC) of the predictive model was 0.709 (95% CI: 0.649-0.769), which was significantly higher than the CER (0.646, 95% CI: 0.584-0.709), interval time (0.563, 95% CI: 0.495-0.631) and CEA level (0.586, 95% CI: 0.518-0.655). In ultra-low rectal patients, multivariate logistic regression analysis revealed that CER (≤ 2/3 cycle vs > 2/3 cycle, P = .003, OR = 7.203, 95% CI: 1.934-26.823) and mismatch repair (MMR) status (pMMR vs dMMR, P = .016, OR = 0.173, 95% CI: 0.041-0.720) were predictive factors for pCR. The AUC of the predictive model was 0.653 (95% CI: 0.474-0.832). Conclusion: New predictive models were varied by the histologic types and MMR statuses to evaluate the trend of tumor response to nCRT in all RC cases and ultra-low RC patients, which may be used to individualize stratify for selected LARC patients.

Abstract
BACKGROUND Approximately 20 percent of patients with a tumour localized in the low rectum still encounter the possibility of requiring permanent stoma (PS), which can cause drastic changes in lifestyle and physical perceptions.
AIM To determine the risk factors for PS and to develop a prediction model to predict the probability of PS in rectal cancer patients after sphincter-saving surgery.
METHODS A retrospective cohort of 421 rectal cancer patients who underwent radical surgery at Taipei Medical University Hospital between January 2012 and December 2020 was included in this study. Univariate and multivariate analyses were performed to identify the independent risk factors for PS. A nomogram was developed according to the independent risk factors obtained in the multivariate analysis. The performance of the nomogram was assessed using a receiver operating characteristic curve and a calibration curve.
RESULTS The PS rate after sphincter-saving surgery was 15.1% (59/391) in our study after a median follow-up of 47.3 mo (range 7–114 mo). Multivariate logistic regression analysis demonstrated that local recurrence, perirectal abscess, anastomosis site stenosis, perineural invasion, tumor size and operative time were independent risk factors for PS. These identified risk factors were incorporated into the nomogram, and the concordance index of this model was 0.903 (95%CI: 0.851-0.955). According to the calibration curves, the nomogram represents a perfect prediction model.
CONCLUSION Several risk factors for PS after sphincter-saving surgery were identified. Our nomogram exhibited perfect predictive ability and will improve a physician’s ability to communicate the benefits and risks of various treatment options in shared decision making.

Abstract
BACKGROUND Anastomotic stenosis is a common complication of colorectal cancer surgery with anastomosis. Transanal minimally invasive surgery is a novel approach to the treatment of anastomotic stenosis. OBJECTIVE This study aimed to evaluate the efficacy and safety of transanal minimally invasive surgery for anastomotic stenosis treatment. DESIGN This was a retrospective study. SETTINGS This study was conducted at a comprehensive cancer center. PATIENTS This study included patients with rectal anastomotic stenosis who after undergoing colorectal surgery were admitted to the Sir Run Run Shaw Hospital between September 2017 and June 2019. MAIN OUTCOME MEASURES The primary outcome was the operative success rate. The secondary outcomes were intraoperative variables, postoperative complications, stoma closure conditions, and stenosis recurrence risks. RESULTS Nine patients, aged 52 to 80 years, with a history of colorectal cancer with end-to-end anastomosis underwent transanal minimally invasive surgery for anastomotic stenosis. The distance between the stenosis and the anal verge ranged from 5 to 12 cm. The mean stenosis diameter was 0.3 cm. Four patients had completely obstructed rectal lumens. Eight of 9 patients successfully underwent transanal minimally invasive surgery radial incision and cutting. The average operation time was 50 minutes. After the procedure, 1 patient had symptomatic procedure-associated perforations but recovered with conservative treatment. No perioperative mortality occurred. One patient underwent transverse colostomy 1 month after transanal minimally invasive surgery because of proximal colon ischemia induced by primary rectal surgery. Eight patients underwent protective loop ileostomy. After transanal minimally invasive surgery, stoma closure was performed in 88% of patients with no stenosis recurrence or obstruction at follow-up (21-42 mo). LIMITATIONS This study was limited by its small sample size and single-center design. CONCLUSIONS Transanal minimally invasive surgery provides an excellent operative field, good maneuverability, and versatile instrumentation and is a safe and effective treatment for rectal anastomotic stenosis, especially for severe fibrotic stenosis or complete obstruction.

Comparative survival risks in patients undergoing abdominoperineal resection and sphincter-saving operation for rectal cancer: a 10-year cohort analysis using propensity score matching. Int J Colorectal Dis 2022; 37:989-997. [PMID: 35378615 DOI: 10.1007/s00384-022-04138-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/26/2022] [Indexed: 02/04/2023]
Abstract
PURPOSE Abdominoperineal resection (APR) has been considered to have a higher risk of local recurrence and poorer survival outcome than sphincter-saving operation (SSO) in patients with rectal cancer. This study compared long-term oncologic outcomes and prognostic parameters in propensity score-matched patients who underwent APR and SSO. METHODS This study analyzed 958 consecutive patients with lower rectal cancer who underwent preoperative chemoradiotherapy followed by APR or SSO between 2005 and 2015. Propensity score matching analysis was performed to adjust baseline characteristics, including clinical stage, tumor distance from the anal verge, and tumor size. RESULTS In the entire cohort, the APR group had larger and lower tumors and showed significantly shorter 5-year disease-free survival (DFS) than the SSO group (64.5% vs. 75.8%, p = 0.01). After propensity score matching, there were no significant between-group differences in local (9.5% vs. 8.0%, p = 0.59) and systemic (27.9% vs. 23.4%, p = 0.3) recurrence rates, and 5-year DFS (67.5% vs. 69.9%, p = 0.49) and overall survival (80.8% vs. 82.9%, p = 0.65) rates. A lower number of lymph nodes retrieved was independently associated with recurrence and survival outcomes in the APR group, whereas poorly differentiated histology was an independent associated parameter in the SSO group. Advanced stage and perineural invasion were identified as independent prognostic parameters in both groups. CONCLUSIONS This study indicated that the long-term oncologic outcomes of APR were comparable to those of SSO. Because prognostic parameters associated with oncologic outcomes differed between the respective procedures, correctable parameters could be ameliorated through complete total mesorectal excision and personalized systemic treatment.

Abstract
Whole-block imaging (WBI) using micro-computed tomography (micro-CT) allows the nondestructive reconstruction of a three-dimensional view of tissues, implying that WBI may be used for accurate pathological evaluation of patients with rectal cancer. HOWEVER, the clinical impact of this approach is unclear. We aimed to clarify the efficacy of WBI in the whole-mount specimens of locally advanced rectal cancer. A total of 237 whole-mount formalin-fixed paraffin-embedded blocks from 13 patients with rectal cancer who underwent surgical treatment were enrolled and scanned with micro-CT to generate three-dimensional images. WBI was evaluated following the conventional pathological review of the corresponding whole-slide imaging (WSI). WBI identified all tumor sites detected using WSI. Furthermore, WBI revealed one additional tumor site, which was not detected using WSI. Tumor resection margin was significantly closer to the soft-tissue edge when measured using WBI (7.7 mm vs. 6.6 mm, p < 0.01). Seventy-six percent of tumor deposits on WSI were changed according to the evidence of tumor interaction with the surrounding tissues confirmed using WBI. Furthermore, WBI revealed 25 additional lymph nodes, six of which were metastatic. The combination of conventional hematoxylin and eosin-stained imaging and WBI may contribute to an accurate pathological assessment.

Abstract
BACKGROUND Postoperative benign anastomotic stricture is associated with colorectal anastomosis following surgery for colorectal cancer. Endoscopic stricturotomy is a novel technique that has been demonstrated to be safe and effective for the treatment of colorectal anastomotic stricture in several case reports and series. OBJECTIVE We designed this study to investigate the efficacy of endoscopic stricturotomy for postoperative benign anastomotic stricture in patients for colorectal cancer. The primary outcomes were stricture-recurrence-free survival and reoperation-free survival. DESIGN This is a retrospective study. SETTING This study presents a single-center experience. PATIENTS This retrospective study included patients with colorectal cancer who underwent surgical resection and developed anastomotic stricture between January 2014 and June 2019 and were treated with endoscopic stricturotomy. MAIN OUTCOME MEASURES Immediate technical success of endoscopic stricturotomy and the factors associated with success and recurrence were investigated. RESULTS Endoscopic stricturotomy was performed in 57 patients, and immediate technical success was achieved in 84% of the patients. The mean follow-up was 31.3 (15.8) months (range, 9-74 months). Postoperative benign anastomotic stricture recurred in 11 patients after initial successful endoscopic stricturotomy; 10 of the 11 recurrent patients accepted reoperation. Univariate and multivariate analysis indicated that length of stricture ≥1 cm was an independent risk factor for failure of the initial endoscopic stricturotomy (OR, 9.423; 95% CI, 1.729-51.350; p = 0.010) and the recurrence of postoperative benign anastomotic stricture after the initial endoscopic stricturotomy (OR, 13.521; 95% CI, 2.305-79.306; p = 0.004). LIMITATIONS The study was limited by its small sample size and retrospective design. CONCLUSIONS Endoscopic stricturotomy is a safe and effective technique for postoperative benign anastomotic stricture. However, if the length of the stricture is ≥1 cm, endoscopic stricturotomy may not be effective, and recurrence of postoperative benign anastomotic stricture is also likely.

ESTRICTUROTOMA ENDOSCPICA PARA PACIENTES CON ESTRICCIN ANASTOMTICA BENIGNA POSTOPERATORIA PARA EL CNCER COLORRECTAL ANTECEDENTES:La estenosis anastomótica benigna postoperatoria se asocia con anastomosis colorrectal después de la cirugía para el cáncer colorrectal. La estricturotomia endoscópica es una técnica novedosa que se ha demostrado que es segura y efectiva para el tratamiento de la estenosis anastomótica colorrectal en varios informes de casos o series.OBJETIVO:Diseñamos este estudio para investigar la eficacia de la estricturotomia endoscópica para la estenosis anastomótica benigna postoperatoria en pacientes con cáncer colorrectal. El resultado primario fue la supervivencia libre de restricción estricta y la supervivencia libre de reoperación.DISEÑO:Este es un estudio retrospectivo.CONFIGURACIÓN:Este estudio presenta una experiencia de un solo centro.PACIENTES:Este estudio retrospectivo incluyó pacientes con cáncer colorrectal que se sometieron a resección quirúrgica y desarrollaron estenosis anastomótica entre enero de 2014 y junio de 2019 y tratados con estricturotomia endoscópica.MEDIDAS PRINCIPALES DE RESULTADO:Éxito técnico inmediato y estenosurotomía endoscópica, los factores asociados con el éxito y la recurrencia.RESULTADOS:Se realizó estricturotomia endoscópica en 57 pacientes, y se logró un éxito técnico inmediato en el 84% de los pacientes. El seguimiento medio fue de 31,3 (15,8) meses (rango, 9 a 74 meses), el POBAS se repitió en 11 pacientes después del éxito inicial de ESt. 10 de los 11 pacientes recurrentes aceptaron la reoperación. El análisis univariado y multivariado indicó que la longitud de la estenosis ≥1 cm era un factor de riesgo independiente para el fracaso de la estricturotomia endoscópica inicial (odds ratio = 9,423; IC del 95% = 1.729-51.350; p = 0.010) y la recurrencia de estenosis anastomótica benigna postoperatoria después de la estricturotomia endoscópica inicial (odds ratio = 13,521; IC del 95% = 2,305-79,306; p = 0.004).LIMITACIONES:El estudio estuvo limitado por su pequeño tamaño de muestra y diseño retrospectivo.CONCLUSIONES:La estricturotomia endoscópica es una técnica segura y efectiva para la estructura anastomótica benigna postoperatoria. Sin embargo, si la longitud de la estenosis es ≥1 cm, la estricturotomia endoscópica puede no ser efectiva y también es probable que se repita la estenosis anastomótica benigna postoperatoria.

Abstract
PURPOSE To develop French guidelines by experts to standardize data acquisition, image interpretation, and reporting in rectal cancer staging with magnetic resonance imaging (MRI). MATERIALS AND METHODS Evidence-based data and opinions of experts of GRERCAR (Groupe de REcherche en Radiologie sur le CAncer du Rectum [i.e., Rectal Cancer Imaging Research Group]) and GRECCAR (Groupe de REcherche en Chirurgie sur le CAncer du Rectum [i.e., Rectal Cancer Surgery Research Group]) were combined using the RAND-UCLA Appropriateness Method to attain consensus guidelines. Experts scoring of reporting template and protocol for data acquisition were collected; responses were analyzed and classified as "Recommended" versus "Not recommended" (when ≥ 80% consensus among experts) or uncertain (when < 80% consensus among experts). RESULTS Consensus regarding patient preparation, MRI sequences, staging and reporting was attained using the RAND-UCLA Appropriateness Method. A consensus was reached for each reporting template item among the experts. Tailored MRI protocol and standardized report were proposed. CONCLUSION These consensus recommendations should be used as a guide for rectal cancer staging with MRI.

Abstract
Magnetic resonance imaging (MRI) has gained increasing importance in the management of rectal cancer over the last two decades. The role of MRI in patients with rectal cancer has expanded beyond the tumor-node-metastasis (TNM) system in both staging and restaging scenarios and has contributed to identifying "high" and "low" risk features that can be used to tailor and personalize patient treatment; for instance, selecting the patients for neoadjuvant chemoradiation (NCRT) before the total mesorectal excision (TME) surgery based on risk of recurrence. Among those features, the status of the circumferential resection margin (CRM), extramural vascular invasion (EMVI), and tumor deposits (TD) have stood out. Moreover, MRI also has played a role in surgical planning, especially when the tumor is located in the low rectum, when the relationship between tumor and the anal canal is important to choose the best surgical approach, and in cases of locally advanced or recurrent tumors invading adjacent pelvic organs that may require more complex surgeries such as pelvic exenteration. As approaches using organ preservation emerge, including transanal local excision and "watch-and-wait", MRI may help in the patient selection for those treatments, follow up, and detection of tumor regrowth. Additionally, potential MRI-based prognostic and predictive biomarkers, such as quantitative and semi-quantitative metrics derived from functional sequences like diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE), and radiomics, are under investigation. This review provides an overview of the current role of MRI in rectal cancer in staging and restaging and highlights the main areas under investigation and future perspectives.

Abstract
BACKGROUND Randomized studies have validated laparoscopic proctectomy for the treatment of rectal cancer as noninferior to an open proctectomy, but most of those studies have included sphincter-preserving resections along with abdominoperineal resection. OBJECTIVE This study aimed to compare perioperative and long-term oncological outcomes between minimally invasive and open abdominoperineal resection. DESIGN This study is a retrospective analysis of a prospectively maintained database. SETTINGS The study was conducted in a single specialized colorectal surgery department. PATIENTS All patients who underwent abdominoperineal resection for primary rectal cancer between 2000 and 2016 were included. MAIN OUTCOME MEASURES The primary outcomes measured were the perioperative and long-term oncological outcomes. RESULTS We included 452 patients, 372 in the open group and 80 in the minimally invasive group, with a median follow-up time of 74 months. There were significant differences between the groups in terms of neoadjuvant radiation treatment (67.5% of the open versus 81.3% of the minimally invasive group, p = 0.01), operative time (mean of 200 minutes versus 287 minutes, p < 0.0001), and mean length of stay (9.5 days versus 6.6 days, p < 0.0001). Overall complication rates were similar between the groups (34.5% versus 27.5%, p = 0.177). There were no significant differences in the mean number of lymph nodes harvested (21.7 versus 22.2 nodes, p = 0.7), circumferential radial margins (1.48 cm versus 1.37 cm, p = 0.4), or in the rate of involved radial margins (10.8% versus 6.3%, p = 0.37). Five-year overall survival was 70% in the open group versus 80% in the minimally invasive group (p = 0.344), whereas the 5-year disease-free survival rate in the open group was 63.2% versus 77.6% in the minimally invasive group (p = 0.09). LIMITATIONS This study was limited because it describes a single referral institution experience. CONCLUSIONS Although both approaches have similar perioperative outcomes, the minimally invasive approach benefits the patients with a shorter length of stay and a lower risk for surgical wound infections. Both approaches yield similar oncological technical quality in terms of the lymph nodes harvested and margins status, and they have comparable long-term oncological outcomes.

Hubo diferencias significativas entre los grupos en términos de tratamiento con radiación neoadyuvante (67,5% del grupo abierto versus 81,3% del grupo mínimamente invasivo, p = 0,01), tiempo operatorio (media de 200 minutos versus 287 minutos, p < 0,0001) y la duración media de la estancia (9,5 días frente a 6,6 días, p < 0,0001). Las tasas generales de complicaciones fueron similares entre los grupos (34,5% versus 27,5%, p = 0,177). No hubo diferencias significativas en el número medio de ganglios linfáticos extraídos (21,7 versus 22,2 ganglios, p = 0,7), márgenes radiales circunferenciales (1,48 cm y 1,37 cm, p = 0,4), ni en la tasa de márgenes radiales afectados (10,8 cm). % versus 6,3%, p = 0,37). La supervivencia general a 5 años fue del 70% en el grupo abierto frente al 80% en el grupo mínimamente invasivo (p = 0,344), mientras que la tasa de supervivencia libre de enfermedad a 5 años en el grupo abierto fue del 63,2% frente al 77,6% en el grupo mínimamente invasivo (p = 0,09).LIMITACIONES:Experiencia en una institución de referencia única.CONCLUSIONES:Si bien ambos tienen resultados perioperatorios similares, el enfoque mínimamente invasivo, beneficia a los pacientes con estadía más corta y menor riesgo de infecciones de la herida quirúrgica. Ambos enfoques, producen una calidad técnica oncológica similar en términos de ganglios linfáticos extraídos y estado de los márgenes, y tienen resultados oncológicos comparables a largo plazo.

Abstract
Background The operative results of different approaches for the laparoscopic intersphincteric resection (LAISR) of low rectal cancer vary, and the patient characteristics associated with the best outcomes for each procedure have not been reported. We compared the efficacy of different approaches for LAISR of low rectal cancer and discussed the surgical indications for each approach. Methods We retrospectively reviewed data from 235 patients with low rectal cancer treated via LAISR from October 2010 to September 2016. Patients underwent either the transabdominal approach for ISR (TAISR, n = 142), the transabdominal perineal approach for ISR (TPAISR, n = 57), or the transanal pull-through approach for ISR (PAISR, n = 36). Results The PAISR and TAISR groups exhibited shorter operation times and less intraoperative blood loss than the TPAISR group. The anastomotic distance was shorter in the PAISR and TPAISR groups than in the TAISR group. No differences in the ability to perform radical resection, overall complications, postoperative recovery, Wexner score recorded 12 months after ostomy closure, 3-year disease-free survival, local recurrence-free survival, distant metastasis-free survival, or overall survival (OS) were observed among the three groups. Conclusions TAISR, TPAISR, and PAISR have unique advantages and do not differ in terms of operation safety, patient outcomes, or anal function. TPAISR requires a longer time to complete and is associated with more bleeding and a slower recovery of anal function. PAISR should be considered when TAISR cannot ensure a negative distal margin and the tumor and BMI are relatively small; otherwise, TPAISR is required.

Effect of pathological complete response after neoadjuvant chemoradiotherapy on postoperative complications of rectal cancer: a systematic review and meta-analysis. Tech Coloproctol 2022; 26:163-174. [PMID: 35048217 DOI: 10.1007/s10151-021-02564-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 12/05/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Standard total mesorectal resection has become an important treatment option for locally advanced or high-risk rectal cancer after neoadjuvant chemo-radiotherapy. 15-27% of patients can achieve pathological complete response (PCR) after neoadjuvant chemo-radiotherapy (nCRT). However, the relationship between PCR and postoperative complications remains an important unsolved problem. The objective of this study was to determine whether PCR was associated with the rate of postoperative complications. METHODS This meta-analysis was implemented following the recommendations from Preferred Reporting Items for Systematic Reviews and Meta-Analyses. We searched electronic literature by PubMed, EMBASE, and Google Scholar. Major outcomes of interest included anastomotic leakage, surgical-site infection, reoperation, and any postoperative complications. Other outcomes comprised postoperative hemorrhage, ileus, and mortality. RESULTS Eleven thousand two hundred ninety patients in 9 studies were included in the meta-analysis. The pooled analysis revealed that patients with PCR did not have a higher risk of anastomotic leakage (OR = 1.22, 95% CI 0.92-1.62, p = 0.17), reoperation (OR = 1.13, 95% CI 0.93-1.37, p = 0.22), and any postoperative complications (OR = 1.02, 95% CI 0.91-1.15, p = 0.72) than patients with non-PCR. However, the meta-analysis showed that the PCR group was superior to the non-PCR group in terms of surgical-site infection (9.38% vs. 12.44%OR = 0.68, 95% CI 0.47-0.98; p = 0.04). CONCLUSION PCR might not be related to the occurrence of postoperative complications in rectal cancer patients following nCRT. In addition, PCR might be associated with a lower risk of surgical-site infection.

Abstract
Background: Rectal cancer is a common malignant tumor in the gastrointestinal tract. This work compares the effects of transumbilical laparoscopic surgery (TULS) and laparoscopic-assisted surgery on the anus-preserving effect of low/ultralow rectal cancer. Materials and Methods: Eighty patients with rectal cancer admitted to our hospital from February 2011 to July 2016 were randomly selected and divided into the laparoscopic group and TULS group, 40 cases in each group, all underwent radical anorectal cancer radical surgery. Statistical analysis was performed on surgical-related indicators in the two groups. Results: Two patients converted to open surgery were excluded. Five patients were excluded because of radical abdomen perineal resection for rectal cancer. Six patients were converted to TULS from laparoscopic surgery. Sixty-seven patients in the experimental group successfully completed anus-sparing surgery, and none died during the operation. The compliance rate of the distance between the lower edge of the tumor and the incision edge of the specimen in the TULS group was better than that in the laparoscopic group (P < .05). There were no significant differences between the two groups in terms of surgical time, blood loss, number of lymph node dissections, functional time of voluntary defecation and postoperative complications, tumor-free recurrence rate at 3 years, and 3-year survival rate after surgery (P > .05). Conclusions: The TULS method is safe and feasible in low and ultralow rectal cancer surgery. It has more advantages than laparoscopic-assisted surgery for anus preservation.

Abstract
Surgeons universally dread gastrointestinal anastomotic leaks, yet the precise definition is not widely agreed on despite international consensus guidelines. Likewise, leaks are not uniformly reported which makes comparisons across studies flawed. Leak rates range from 1 to 3% for ileocolonic, 0.5 to 18% for colorectal, and 5 to 19% for coloanal anastomoses. The sequelae of an anastomotic leak vary but generally correlate with the need for a change in clinical management, from minimal changes to the need for reoperation. Short- and long-term outcomes can be life-altering or life-threatening. Temporary or permanent stomas may be necessary and low pelvic anastomotic leaks may affect bowel function. For cancer patients, leaks can delay treatment and negatively affect oncologic outcomes. In Crohn's patients, leaks are associated with higher recurrence rates. In essence, the lack of agreement on the definition of an anastomotic leak inhibits meaningful understand of its epidemiology, prevention, and treatment.

Abstract
AIM Benign anastomotic strictures following colorectal surgical resection are a commonly under-reported complication in up to 30% of patients, with a significant impact upon quality of life. In this systematic review, we aim to assess the utility of endoscopic techniques in avoiding the need for surgical reintervention. METHOD A literature search was performed for published full text articles using the PubMed, Cochrane and Scopus databases. Additional papers were found by scanning the references of relevant papers. RESULTS A total of 34 papers were included, focusing upon balloon dilatation, endoscopic stenting, electroincision, stapler stricturoplasty and cortiocosteroids alone and in combination, with success rates varying from 20% to 100%. The most challenging strictures were reported as those with a narrow lumen, frequently observed following neoadjuvant chemoradiotherapy or an anastomotic leak. Endoscopic balloon dilatation was the most commonly used first-line method; however, repeated dilatations were often required and this was associated with an increased risk of perforation. Although initial success rates for stents were good, patients often experienced stent migration and local symptoms. Only a small number of patients experienced endoscopic management failure and progressed to surgical intervention. CONCLUSION Following identification of an anastomotic stricture and exclusion of underlying malignancy, endoscopic management is both safe and feasible as a first-line option, even if multiple treatment exposures or multimodal management is required. Surgical resection or a defunctioning stoma should be reserved for emergency or failed cases. Further research is required into multimodal and novel therapies to improve quality of life for these patients.

Abstract
Intersphincteric resection (ISR) is the ultimate anus-sparing technique for low rectal cancer and is considered an oncologically safe alternative to abdominoperineal resection. The application of the robotic approach to ISR (RISR) has been described by few specialized surgical teams with several differences regarding approach and technique. This review aims to discuss the technical aspects of RISR by evaluating point by point each surgical controversy. Moreover, a systematic review was performed to report the perioperative, oncological, and functional outcomes of RISR. Postoperative morbidities after RISR are acceptable. RISR allows adequate surgical margins and adequate oncological outcomes. RISR may result in severe bowel and genitourinary dysfunction affecting the quality of life in a portion of patients.

Abstract
Purpose The present study compares the peri/postoperative and oncological outcomes of abdominoperineal resections (APR) and sphincter saving resection (SSR) for low lying rectal cancer. Methods Between January 2001 and December 2014, 176 patients who underwent SSR (n=67) and APR (n=109) for low rectal cancer, without stage IV, were retrieved from a retrospective database. Results With a median follow-up of 66.5 months. The mean total number of harvested lymph nodes was 16.7 (SSR) versus 17.1 (APR) (P=0.801). The advanced T stage was higher in the APR group (82.6%) versus the SSR group (55.2%) (P=0.006). The positive rate of lymph nodes after surgery was significantly higher in the APR group (45.9%) versus SSR group (25.4%) (P<0.05). The 5-year overall survival rates for SSR and APR were 87.3% and 67.6%, respectively (P<0.005). The 5-year disease-free survival rate (DFS) was 83.6% (SSR) versus 65.5% (APR) (P=0.002). The recurrence rate was higher in the APR group (34.9%) versus the SSR group (14.9%) (P=0.004). Local recurrence rate was not different between the two groups. However, distant recurrence rate was significantly higher in the APR group (26.6% vs. 11.9%, P=0.023). In multivariate analysis, node positive (N0 vs. N1-2) was an independent prognostic factor for DFS (P<0.005). Conclusion Based on the present data, SSR achieved better 5-year oncological outcome than APR. The positive lymph node ratio in the N stage after surgery was higher in the APR group and this seems to have an effect on the oncological outcomes of the APR group.

Abstract
BACKGROUND This prospective randomized controlled study was designed to evaluate the effect of biofeedback therapy (BFT) during temporary stoma period to prevent defecation dysfunction after sphincter-preserving surgery (SPS). METHODS Following SPS with temporary stoma, patients were divided according to whether (BFT group) or not (Control group) they received BFT. BFT was performed once or twice a week during the temporary stoma period. Kegel exercise were advised to all the patients. Subjective defecation symptoms were evaluated according to Cleveland Clinic Incontinence Score (CCIS) as primary outcome at 12 months postoperatively. Manometric data of five time-points were also analyzed. RESULTS Twenty-one patients in the BFT group and 23 patients in the control group received anorectal physiologic testing. The incidence of CCIS of more than 9 points, which is the primary end point in this study, was not statistically different between BFT group and control group (p = 1.000). The liquid stool incontinence in the BFT group showed a better tendency (p = 0.06) at 12 months post-SPS. Time-dependent serial changes in maximal sensory threshold (Max RST) was significantly different between the BFT and control groups (p = 0.048). Also, the change of mean resting pressure (MRP) tended to be more stable in the BFT group (p = 0.074). CONCLUSIONS The BFT in the period of temporary stoma may be related to liquid stool incontinence at 12 months post-SPS and lead to stable MRP and better Max RST. Therefore, BFT during temporary stoma might be helpful for preventing and minimizing defecation dysfunction in high risk patients after SPS, NCT01661829).

Cancers (Basel) 2021; 13:4793. [PMID: 34638278 PMCID: PMC8507715 DOI: 10.3390/cancers13194793] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 09/17/2021] [Accepted: 09/21/2021] [Indexed: 12/15/2022] Open
Abstract
The surgical management of low-lying rectal cancer, within 5 cm from the anal verge (AV), is challenging due to the possibility, or not, to preserve the anus with its sphincter muscles maintaining oncological safety. The standardization of total mesorectal excision, the adoption of neoadjuvant chemoradiotherapy, the implementation of rectal magnetic resonance imaging, and the evolution of mechanical staplers have increased the rate of anus-preserving surgeries. Moreover, extensive anatomy and physiology studies have increased the understanding of the complexity of the deep pelvis. Intersphincteric resection (ISR) was introduced nearly three decades ago as the ultimate anus-preserving surgery. The definition and indication of ISR have changed over time. The adoption of the robotic platform provides excellent perioperative results with no differences in oncological outcomes. Pushing the boundaries of anus-preserving surgeries has risen doubts on oncological safety in order to preserve function. This review critically discusses the oncological safety of ISR by evaluating the anatomical characteristics of the deep pelvis, the clinical indications, the role of distal and circumferential resection margins, the role of the neoadjuvant chemoradiotherapy, the outcomes between surgical approaches (open, laparoscopic, and robotic), the comparison with abdominoperineal resection, the risk factors for oncological outcomes and local recurrence, the patterns of local recurrences after ISR, considerations on functional outcomes after ISR, and learning curve and surgical education on ISR.

Safety of Small Circular Staplers in Double Stapling Technique Anastomosis for Sigmoid Colon and Rectal Cancer. Dis Colon Rectum 2021; 64:937-945. [PMID: 33951685 DOI: 10.1097/dcr.0000000000001889] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/13/2022]
Abstract
BACKGROUND Although smaller circular staplers are easier to insert and less likely to involve the vagina and levator ani muscles when performing double stapling technique anastomosis, surgeons often consider that larger circular staplers would be safer in reducing the risk of postoperative anastomotic strictures. OBJECTIVE This study aimed to investigate the safety of using 25-mm circular staplers compared with 28/29-mm staplers in the double stapling technique anastomosis regarding the development of anastomotic strictures and other complications. DESIGN This is a retrospective observational study. SETTING This study was conducted at a single comprehensive cancer center. PATIENTS Consecutive patients undergoing curative colorectal resection with double stapling technique anastomosis for stage I to III sigmoid colon and rectal cancer between 2013 and 2016 were included. MAIN OUTCOME MEASURES The incidence of anastomotic complications (strictures, leakage, and bleeding) was compared between the 25- and 28/29-mm circular staplers. Predictors for anastomotic strictures were investigated with multivariable logistic regression. RESULTS Small (25-mm) staplers were used in 186 (22.8%) of 815 eligible patients. The 25-mm staplers were associated with use in female patients, splenic flexure take down, high tie of the inferior mesenteric artery, and low anastomosis. Overall anastomotic complications (11.8% vs 13.7%, p = 0.51), strictures (5.9% vs 3.3%, p = 0.11), leakage (2.7% vs 3.8%, p = 0.47), and bleeding (4.8% vs 7.6%, p = 0.19) were not different between the 25- and 28/29-mm staplers. From multivariable logistic regression, independent predictors of anastomotic strictures included diverting ostomy and anastomotic leakage, but not small circular stapler use. Most of the 32 anastomotic strictures were successfully treated without surgical intervention (finger dilation, n = 25; endoscopic intervention, n = 5). LIMITATIONS This was a single-center retrospective study. CONCLUSIONS Use of 25-mm circular staplers for double stapling technique anastomosis is safe and does not increase the risk of anastomotic strictures and other anastomotic complications in comparison with larger staplers.

SEGURIDAD DE ENGRAPADORAS CIRCULARES PEQUEAS EN ANASTOMOSIS, CON TCNICA DE DOBLE ENGRAPADO PARA CNCER DE RECTO Y COLON SIGMOIDE ANTECEDENTES:Aunque las engrapadoras circulares más pequeñas son más fáciles de insertar y menos probable que involucren a la vagina y los músculos elevadores del ano, cuando se realiza una anastomosis con técnica de doble engrapado, frecuentemente los cirujanos consideran que las engrapadoras circulares más grandes, serían más seguras para disminuir los riesgos de estenosis anastomóticas postoperatorias.OBJETIVO:El estudio se dirigió para investigar la seguridad en el uso de engrapadoras circulares de 25 mm, en comparación con engrapadoras de 28/29 mm, en anastomosis con técnica de doble engrapado, en relación al desarrollo de estenosis anastomóticas y otras complicaciones.DISEÑO:Estudio observacional retrospectivo.AJUSTE:Centro oncológico integral único.PACIENTES:Se incluyeron pacientes consecutivos sometidos a resección colorrectal curativa, con anastomosis y técnica de doble engrapado, para cáncer de recto y colon sigmoide en estadios I-III entre 2013 y 2016.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon las incidencias de complicaciones anastomóticas (estenosis, fugas y sangrados) entre las engrapadoras circulares de 25 y 28/29 mm. Los predictores para estenosis anastomóticas se investigaron con regresión logística multivariable.RESULTADOS:Entre un total de 815 pacientes elegibles, se utilizaron engrapadoras de 25 mm en 186 (22,8%). Las engrapadoras de 25 mm se asociaron con el uso en pacientes femeninas, descenso del ángulo esplénico, ligadura alta de arteria mesentérica inferior y anastomosis baja. Complicaciones anastomóticas generales (11,8% vs. 13,7%, p = 0,51), estenosis (5,9% vs. 3,3%, p = 0,11), fugas (2,7% vs. 3,8%, p = 0,47) y sangrado (4,8% vs. 7,6%, p = 0,19). No hubo diferencia entre las engrapadoras de 25 y 28/29 mm. En la regresión logística multivariable, predictores independientes de estenosis anastomóticas incluyeron ostomía derivativa y fuga anastomótica, pero no incluyeron el uso de engrapadoras circulares pequeñas. La mayoría de las 32 estenosis anastomóticas se trataron con éxito sin intervención quirúrgica (dilatación del dedo, n = 25; intervención endoscópica, n = 5).LIMITACIONES:Fue un estudio retrospectivo de un solo centro.CONCLUSIONES:El uso de engrapadoras circulares de 25 mm para la anastomosis con técnica de doble engrapado, es seguro y no aumenta el riesgo de estenosis anastomóticas y de otras complicaciones anastomóticas, cuando son comparadas con engrapadoras más grandes.

Abstract
PURPOSE The purpose of this study is to evaluate partial excision of the levator ani muscle (PELM) enables preservation of anal sphincter function although levator ani muscle (LAM) was invaded. METHODS Functional outcomes and oncologic outcomes of 23 consecutive patients who underwent robotic PELM for low rectal cancer at the anorectal ring level invading or abutting the ipsilateral LAM are analysed. RESULTS Secured resection margins were achieved, especially for the circumferential resection margin. During a median follow-up of 44 months, the 3-year local recurrence rate was 14.4%. Among patients who underwent diverting ileostomy closure, mean Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores were 68.3 ± 11.9 and 10.7 ± 5.3, respectively, at 1 year after closure. CONCLUSION PELM is a sphincter-preserving alternative to abdominoperineal resection (APR) or extralevator APR for low rectal cancer invading the ipsilateral LAM at the level of the anorectal ring.

Abstract
This phase III trial included patients with ultra-low rectal adenocarcinoma that initially required abdominoperineal resection. The surgical decision was based on clinical tumour status after preoperative treatment. The overall sphincter-saving resection rate was 85 per cent, with 72 per cent rate of intersphincteric resection. Long-term results showed that changing the initial abdominoperineal resection indication into a sphincter-saving resection according to tumoral response is oncologically safe.

Abstract
Molecular targeted therapy has been proved effective in treatment of rectal cancer. Up-regulated expression of programmed death ligand-1 (PD-L1) was observed after the management of molecular targeted therapy, which made the therapeutic effect discounted. Tumors with higher PD-L1 expression were more sensitive and responsive to treatment of PD-L1 inhibitor. Therefore, the combination of molecular targeted therapy and immune checkpoint blockade makes sense. In this study, the copolymers of poly (ethylene glycol)-block-poly (L-leucine) (PEG-PLLeu) were synthesized as a thermosensitive hydrogel composite for consecutive release of regorafenib (REG) and BMS202. The mechanical properties of PEG-PLLeu were investigated, confirming that PEG-PLLeu (5 wt.%) was suitable for in situ injection as drug-delivery composite at low temperature and stable after sol-gel transition at body temperature. Importantly, the double drug loaded hydrogel showed superior antitumour activity over single drugs in an orthotopic rectal cancer model (CT26-Luc). Further analysis of the tumor tissues suggested that REG upregulated the expression of PD-L1 in tumor tissues. In addition, the immunosuppressive tumor microenvironment of CT26-Luc tumor was distinctly relieved under the effect of BMS202, as characterized by increased infiltration of CD8+ T cells in tumors and enhanced secretion of antitumour cytokines (IFN-γ and TNF-α). Moreover, the drug-loaded composite showed no obvious toxicity in histological analysis. Taken together, the administration of REG and BMS202 in the PEG-PLLeu composite could induce a synergistic effect in in situ treatment of rectal cancer without obvious toxicity, and thus represented a potential strategy for enhanced in situ therapeutic modality.

Abstract
INTRODUCTION Intersphincteric resection (ISR) is the ultimate anal-sparing technique as an alternative to abdominoperineal resection in selected patients. Oncological safety is still debated. This study analyses long-term oncological results and evaluates risk factors for local recurrence (LR) and overall survival (OS) after minimally-invasive ISR. MATERIALS AND METHODS Retrospective single-center data were collected from a prospectively maintained colorectal database. A total of 161 patients underwent ISR between 2008 and 2018. OS and local recurrence-free survival (LRFS) were assessed using Kaplan-Meier analysis (log-rank test). Risk factors for OS and LRFS were assessed with Cox-regression analysis. RESULTS Median follow-up was 55 months. LR occurred in 18 patients. OS and LRFS rates at 1, 3, and 5 years were 96%, 91%, and 80% and 96%, 89%, and 87%, respectively. Tumor size (p = 0.035) and clinical T-stage (p = 0.029) were risk factors for LRFS on univariate analysis. On multivariate analysis, tumor size (HR 2.546 (95% CI: 0.976-6.637); p = 0.056) and clinical T-stage (HR 3.296 (95% CI: 0.941-11.549); p = 0.062) were not significant. Preoperative CEA (p < 0.001), pathological T-stage (p = 0.033), pathological N-stage (p = 0.016) and adjuvant treatment (p = 0.008) were prognostic factors for OS on univariate analysis. Preoperative CEA (HR 4.453 (95% CI: 2.015-9.838); p < 0.001) was a prognostic factor on multivariate analysis. CONCLUSIONS This study confirms the oncological safety of minimally-invasive ISR for locally advanced low-lying rectal tumors when performed in experienced centers. Despite not a risk factor for LR, tumor size and, locally advanced T-stage with anterior involvement should be carefully evaluated for optimal surgical strategy. Preoperative CEA is a prognostic factor for OS.

Abstract
Abstract
Introduction Over the last decades, treatment for rectal cancer has substantially improved with development of new surgical options and treatment modalities. With the improvement of survival, functional outcome and quality of life are getting more attention.
Study objective To provide an overview of current modalities in rectal cancer treatment, with particular emphasis on functional outcomes and quality of life.
Results Functional outcomes after rectal cancer treatment are influenced by patient and tumor characteristics, surgical technique, the use of preoperative radiotherapy and the method and level of anastomosis. Sphincter preserving surgery for low rectal cancer often results in poor functional outcomes that impair quality of life, referred to as low anterior resection syndrome. Abdominoperineal resection imposes the need for a permanent stoma but avoids the risk of this syndrome. Contrary to general belief, long-term quality of life in patients with a permanent stoma is similar to those after sphincter preserving surgery for low rectal cancer.
Conclusion All patients should be informed about the risks of treatment modalities. Decision on rectal cancer treatment should be individualized since not all patients may benefit from a sphincter preserving surgery “at any price”. Non-resection treatment should be the future focus to avoid the need of a permanent stoma and bowel dysfunction.

Abstract
BACKGROUND The long-term effects of radical resection on quality of life may influence the treatment selection. The objective of this study was to determine whether abdominoperineal resection has a better effect on the quality of life than sphincter preservation surgery at 3 years after surgery. METHODS This prospective, cohort study included patients who underwent radical resection for low rectal cancer. The primary outcomes were European Organisation for Research and Treatment of Cancer QLQ-C30 and CR38 quality of life scores 3 years after surgery, which were compared with linear generalised estimating equations, after adjustment for baseline values, a time effect, and an interaction effect between time and treatment. The secondary outcomes included sexual-urinary functions and oncological outcomes. The study was registered with ClinicalTrials.gov (NCT01461525). FINDINGS Between December 2011 and August 2016, 342 patients were enrolled: 268 (78•4%) underwent sphincter preservation surgery and 74 (21•6%) underwent abdominoperineal resection. The global quality of life scores did not differ between sphincter preservation surgery and abdominoperineal resection groups (adjusted mean difference, 4•2 points on a 100-point scale; 95% confidence interval [CI], -1•3 to 9•7, p = 0•1316). Abdominoperineal resection was associated with a worse body image (9•8 points; 95% CI, 2•9 to 16•6, p = 0•0052), micturition symptoms (-8•0 points; 95% CI, -14•1 to -1•8, p = 0•0108), male sexual problems (-19•9 points; 95% CI, -33•1 to -6•7, p = 0•0032), less confidence in getting and maintaining an erection in males (0•5 points on a 5-point scale; 95% CI, 0•1 to 0•8, p = 0•0155), and worse urinary symptoms (-5•4 points on a 35-point scale; 95% CI, -8•0 to -2•7, p < 0•0001). The 5-year overall survival was worse with abdominoperineal resection in unadjusted (92•2% vs 80•9%; difference 11•3%, hazard ratio 2•38; 95% CI, 1•27 to 4•46, p = 0•0052), but did not differ after adjustment. INTERPRETATION In this long-term prospective study, abdominoperineal resection failed to meet the superiority to sphincter preservation surgery in terms of quality of life. Although the global quality of life scores did not differ between groups, this study suggests that sphincter preservation surgery can be an acceptable alternative to abdominoperineal resection for low rectal cancer, offering a better quality of life and sexual-urinary functions, with no increased oncological risk even after 3 years.

Abstract
AIM There are few data evaluating the long-term outcomes of intersphincteric resection (ISR), especially the impact of inclusion of more juxtapositioned and intra-anal tumours on oncological and functional outcomes. We compared the oncological and functional results of patients treated by total mesorectal excision and ISR for low rectal cancer over a 25-year period. METHOD This is a retrospective study from a single institution evaluating results of ISR over three periods: 1990-1998, 1999-2006 and 2007-2014. Patients treated by partial or total ISR, with or without neoadjuvant chemoradiotherapy, for low rectal cancer (≤ 6 cm from the anal verge) were included. We compared postoperative morbidity, quality of surgery and oncological and functional outcomes in the time periods studied. RESULTS Of 813 patients operated on for low rectal cancer, 303 had ISR. Tumour stage did not differ; however, the distance of the tumour from the anorectal junction decreased from 1 to 0 cm (P < 0.001) and the distal resection margin shortened from 25 to 10 mm (P < 0.001) from 1990 to 2014. The postoperative morbidity and quality of surgery did not change significantly over time. The 5-year local recurrence (4.3% vs 5.9% vs 3.5%; P = 0.741) and disease-free survival (72% vs 71% vs 75%; P = 0.918) did not differ between the three time periods. Functional results improved during the last period; however, overall 42% of patients experienced major bowel dysfunction. CONCLUSION Pushing the envelope of sphincter-saving resection in ultra-low rectal cancer reaching or invading the anal sphincter did not compromise oncological and functional outcomes. The main limitation of the ISR procedure appears to be functional rather than oncological, suggesting that bowel rehabilitation programmes should be developed.

Abstract
BACKGROUND Rate of abdominoperineal resection (APR) varies from countries and surgeons. Surgical impact of preoperative treatment for ultra-low rectal carcinoma (ULRC) initially indicated for APR is debated. We report the 10-year oncological results from a prospective controlled trial (GRECCAR 1) which evaluate the sphincter saving surgery (SSR). METHODS ULRC indicated for APR were included (n = 207). Randomization was between high-dose radiation (HDR, 45 + 18 Gy) and radiochemotherapy (RCT, 45 Gy + 5FU infusion). Surgical decision was based on tumour volume regression at surgery. SSR technique was standardized as mucosectomy (M) or partial (PISR)/complete (CISR) intersphincteric resection. RESULTS Overall SSR rate was 85% (72% ISR), postoperative morbidity 27%, with no mortality. There were no significant differences between the HDR and RCT groups: 10-year overall survival (OS10) 70.1% versus 69.4%, respectively, 10.2% local recurrence (9.2%/14.5%) and 27.6% metastases (32.4%/27.7%). OS and disease-free survival were significantly longer for SSR (72.2% and 60.1%, respectively) versus APR (54.7% and 38.3%). No difference in OS10 between surgical approaches (M 78.9%, PISR 75.5%, CISR 65.5%) or tumour location (low 64.8%, ultralow 76.7%). CONCLUSION GRECCAR 1 demonstrates the feasibility of safely changing an initial APR indication into an SSR procedure according to the preoperative treatment tumour response. Long-term oncologic follow-up validates this attitude.

Abstract
The management of rectal cancer is complex and continually evolving. With advancements in technology and the use of multidisciplinary teams to guide the treatment decision making, staging, oncologic, and functional outcomes are improving, and the management is moving toward personalized treatment strategies to optimize each individual patient's outcomes. Key in this evolution is imaging. Magnetic resonance imaging (MRI) has emerged as the dominant method of pelvic imaging in rectal cancer, and use of MRI for staging is best practice in multiple international guidelines. MRI allows a noninvasive assessment of the tumor site, relationship to surrounding structures, and provides highly accurate rectal cancer staging, which is necessary for determining the appropriate treatment strategy. However, the applications of MRI extend far beyond pretreatment staging. MRI can be used to predict outcomes in locally advanced rectal cancer and guide the surgical or nonsurgical plan, serving as a predictive and prognostic biomarker. With continued MRI hardware improvement and new sequence development, MRI may offer new perspectives in the assessment of treatment response and new innovations that could provide better insight into the staging, restaging, and outcomes with rectal cancer.

Latest Advances in Intersphincteric Resection for Low Rectal Cancer. Gastroenterol Res Pract 2020; 2020:8928109.

Abstract
Background Intersphincteric resection (ISR) has been a preferable alternative to abdominoperineal resection (APR) for anal preservation in patients with low rectal cancer. Laparoscopic ISR and robotic ISR have been widely used with the proposal of 2 cm or even 1 cm rule of distal free margin and the development of minimally invasive technology. The aim of this review was to describe the newest advancements of ISR. Methods A comprehensive literature review was performed to identify studies on ISR techniques, preoperative chemoradiotherapy (PCRT), complications, oncological outcomes, and functional outcomes and thereby to summarize relevant information and controversies involved in ISR. Results Although PCRT is employed to avoid positive circumferential resection margin (CRM) and decrease local recurrence, it tends to engender damage of anorectal function and patients' quality of life (QoL). Common complications after ISR include anastomotic leakage (AL), anastomotic stricture (AS), urinary retention, fistula, pelvic sepsis, and prolapse. CRM involvement is the most important predictor for local recurrence. Preoperative assessment and particularly rectal endosonography are essential for selecting suitable patients. Anal dysfunction is associated with age, PCRT, location and growth of anastomotic stoma, tumour stage, and resection of internal sphincter. Conclusions The ISR technique seems feasible for selected patients with low rectal cancer. However, the postoperative QoL as a result of functional disorder should be fully discussed with patients before surgery.

Abstract
As therapeutic options to treat rectal cancers have advanced over the last several decades, MRI has become the standard of care for baseline local tumor and nodal staging of rectal cancers. An understanding of the technique, anatomy, tumor appearance, and elements of staging on MRI is essential to provide prognostic information and to guide neoadjuvant chemoradiation and surgical treatment. We provide a framework for imaging the rectum on MRI followed by a practical case-based approach to interpretation of pre-treatment MRI of the rectum in evaluation of rectal cancers, with examples and illustrations of the range of local tumor (T) stage and nodal (N) disease involvement. This approach can be paired with standardized reporting templates to support clear, accurate and clinically relevant imaging assessment of rectal cancers.

Abstract
BACKGROUND This study primarily aimed to assess the impact of prolonged neoadjuvant treatment-surgery interval (PNSI) on histopathologic and postoperative outcomes. Impacts of the mode of neoadjuvant treatment (NT) and surgery on the outcomes were also evaluated in the same patient population. PATIENTS AND METHODS Between February 2011 and December 2017, patients who underwent NT and total mesorectal excision for locally advanced rectal cancer were included. PNSI was defined as >4 and >8 weeks after short-course and long-course NT modalities, respectively. RESULTS A total of 44 (27%) patients received short-course NT (standard interval: n=28; PNSI: n=16) and 122 (73%) patients received long-course NT (standard interval: n=39; PNSI: n=83). Postoperative morbidity was similar between the standard interval and PNSI in patients undergoing short-course [n=3 (11%) vs. n=3 (19%), P=0.455] and long-course [n=6 (15%) vs. n=16 (19%), P=0.602] NT. PNSI was associated with increased complete pathologic response in patients receiving short-course NT [0 vs. n=5 (31%), P=0.002]. Compared with short-course NT, long-course NT was superior in terms of tumor response based on the Mandard [Mandard 1 to 2: n=6 (21%) vs. 6 (38%), P=0.012] and the College of American Pathologists (CAP) [CAP 0 to 1: n=13 (46%) vs. n=8 (50%), P=0.009] scores. Postoperative morbidity was similar after open, laparoscopic, and robotic total mesorectal excision [n=1 (14.2%) vs. n=21 (21%) vs. n=6 (12.5%), P=0.455] irrespective of the interval time to surgery and the type of NT. CONCLUSIONS PNSI can be considered in patients undergoing short-course NT due to its potential oncological benefits. The mode of surgery performed at tertiary centers has no impact on postoperative morbidity after both NT modalities.

Int J Clin Oncol 2020; 25:1653-1662.

Abstract
PURPOSE Neoadjuvant therapy is routinely used in the management of locally advanced rectal cancer. This study aimed to evaluate the predictive value of pathological parameters in tumor response after treatment. METHODS We reviewed the hematoxylin-eosin slides from pretreatment biopsies of 150 rectal cancer patients who received preoperative chemoradiotherapy (PCRT) at Sun Yat-sen University Cancer Center between May 2013 and June 2016. Pathological and clinical parameters were both studied. The tumor response after chemoradiotherapy was evaluated using the tumor regression grade (TRG). Logistic regression was used to evaluate the relevance between these parameters and tumor response. RESULTS Complete tumor response (TRG0 and pCR) to PCRT was identified in 40 (26.7%) patients. The pCR rate was 93.33% (14 of 15) in cases with signet ring cell component versus 19.26% (26 of 135) in those without signet ring cell component (p < 0.001). Four cases with signet ring cell component were evaluated as clinical complete response (cCR), all of whom also achieved pCR; in contrast, only 9 of 15 (60%) cCR cases without signet ring cell achieved pCR. CONCLUSION Our data suggest that the signet ring cell component in pretreatment biopsies may be a potential predictor of tumor response to PCRT in rectal cancer. This suggests patients with clinical complete response are more suitable for a wait-and-watch approach.

Abstract
BACKGROUND The aim of this study is to compare the postoperative quality of life (QoL) and survival outcomes in lower rectal cancer (LRC) patients who undergo either laparoscopic- intersphincteric resection or extralevator abdominoperineal excision (L-ELAPE) after long-course neoadjuvant chemoradiation therapy (nCRT). METHODS This prospective, single-center, non-randomized, controlled, non-blinded, phase I/II clinical trial is designed to enroll 159 eligible LRC patients who achieved favorable response to long-course nCRT (2 × 25 Gy). After informed consent, the patients will be assigned into the laparoscopic intersphincteric resection group or L-ELAPE group according to their own will. Standard radical laparoscopic surgeries will be performed for every participant. Then every participant will be followed up for 3 years. The primary outcomes are scores of QoL questionnaire-core 30, QoL questionnaire-colorectum 29, Wexner incontinence score, International Prostate Symptom Score (for male), International Index of Erectile Function-5 (for male) and Female Sexual Function Index (for female). The secondary outcomes consist of incomplete circumferential resection margin rate, 3-year local recurrence, 3-year disease-free survival, 3-year overall survival and other surgical outcomes. DISCUSSION This is the first prospective clinical controlled trial to assess postoperative QoL and efficacy for LRC patients after favorable long-course nCRT. The result is expected to provide new evidence for a more detailed individualized treatment guideline for LRC. TRIAL REGISTRATION This trial was registered at Chinese Clinical Trial Registry (ChiCTR1800017512; ChiCTR.org) on August 2, 2018.

Risk factors and endoscopic treatment for anastomotic stricture after resection in patients with colorectal cancer. REVISTA DE GASTROENTEROLOGÍA DE MÉXICO 2020; 86:44-50. [PMID: 32386994 DOI: 10.1016/j.rgmx.2020.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Revised: 02/12/2020] [Accepted: 03/05/2020] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Benign strictures are frequent complications following colorectal surgery, with an incidence of up to 20%. Endoscopic treatment is safe and effective but there is not enough evidence for establishing stricture management at that anatomic level. AIM To determine the risk factors associated with the development of stricture in patients with colorectal cancer and describe endoscopic treatment in those patients. MATERIALS AND METHODS A retrospective study was conducted on patients with colorectal cancer that underwent surgery and anastomosis, evaluated through colonoscopy, within the time frame of 2014 to 2019. RESULTS Of the 213 patients included in the study, 18.3% presented with stricture that was associated with the type of surgery. Intersphincteric resection was a risk factor (OR = 18.81, 95% CI: 3.31-189.40, p < .001). A total of 69.2% patients with stricture had a stoma, identifying it as a risk factor for stricture (OR = 7.07, 95% CI: 3.10-16.57, p < .001). Mechanical anastomotic stapling was performed in 87.4% of the patients that did not present with stricture, identifying it as a protective factor (OR = 0.41, 95% CI: 0.16-1.1, p = .04). Endoscopic treatment was required in 69.2% of the patients and provided favorable results in 83.3%. Only 2.6% of the patients had recurrence. No complications were reported. CONCLUSION Intersphincteric resection and the presence of a stoma were independent risk factors for stricture, and mechanical anastomosis was a protective factor against stricture development. Endoscopic treatment was safe and effective.

Abstract
Local excision following chemoradiotherapy in rectal cancer is an organ-preserving procedure which aims at reducing morbidity and functional disorders associated with total mesorectal excision (TME) in selected patients. Although TME after chemoradiotherapy remains the gold standard for locally advanced mid and low rectal cancer, in the last years multicenter research trials have offered encouraging oncologic results which have allowed to preserve the rectum in patients with a pathologic complete response after chemoradiotherapy. A review of the available literature on this topic was conducted to define the state of the art of this conservative approach and to focus on the most controversial aspects concerning local excision performed after chemoradiotherapy, in particular tumor scatter and lymph node status, completion and salvage surgery, morbidity and quality of life. The analysis of these topics should be considered, in trial setting or in current practice, for their clinical implications. Oncologic outcomes of recent trials are encouraging for part of the patients presenting T2 rectal cancer; however, TME still remains the standard treatment in clinical practice. In such cases, local excision should include a surgical safety margin of at least 1 cm from the resection margin to achieve a true negative margin from residual tumor cells. The selection of the patients should be carefully performed and their consensus extremely detailed because TME is necessary in about 30% of cases. Failing that, morbidity and quality of life are negatively affected. However, about half of these patients refuse radical surgery (45%), thus undergoing only palliative care.

Abstract
BACKGROUND Despite acceptable oncologic outcomes of sphincter preserving surgeries for low rectal cancer, bowel dysfunction occurs. This study aimed to compare the oncologic and functional bowel outcomes between ultralow anterior resection (ULAR) and intersphincteric resection (ISR) for low rectal cancer. METHODS One hundred sixty-four patients who underwent ULAR with or without ISR for low rectal cancer between December 2010 and May 2018 were included. The Wexner and Memorial Sloan Kettering Cancer Center (MSKCC) scores were used to evaluate the bowel function of patients. Overall survival (OS) and disease-free survival (DFS) were compared between patients. RESULTS The ISR group had higher incidence of major fecal incontinence than the ULAR group (75.9% vs 49.3%; P = .016). The median Wexner score decreased from 12 to 9 (P = .062) at 1-year follow-up. However, the frequency and urgency/soilage subscales of MSKCC score improved significantly in the ULAR group. ISR and follow-up interval less than 1-year significantly increased the major incontinence risk. The OS in the ULAR and ISR groups was 91.4% and 91.7%. Whereas the DFS in both groups was 79% and 79.2%, respectively. CONCLUSION ULAR and ISR are comparable in oncologic outcomes. Severe bowel dysfunctions and major incontinence were noted in ISR group. Careful selection of patients is mandatory.

Abstract
Background: This study represents a prospective analysis of a series of laparoscopic ultra low anterior resection (ULAR) done at a laparoscopic surgical center to assess the surgical outcome, oncological efficacy, and quality of life after surgery. Methods: Over a period of 6 years (2013-2018), 43 patients aged between 40 and 68 years, with very low rectal cancers (3-6 cm from the anal verge), within T3N1M0 stage, assessed by positron emission tomography-computed tomography and pelvic magnetic resonance imaging, underwent neoadjuvant chemoradiotherapy (nCRT) followed by laparoscopic ULAR and simultaneous diversion ileostomy. Results: The overall complication rate was low and there was an overall leak rate of 9.3% with a radiological leak (Grade A) in 3 of the 43 patients (7%), but only 1 (2.3%) patient required a local lavage and a resuturing for secondary hemorrhage. Recurrence was seen in 2/43 (4.7%), one of whom had a conversion to abdominoperineal resection. The other had distant metastasis and refused further treatment. The functional outcome is assessed in 41 (95.3%) patients by low anterior resection syndrome (LARS) score and a reasonable quality of life with major LARS was seen in only 7.3% of the patients at a follow-up ranging from 1 to 6 years. Conclusion: The nCRT followed by laparoscopic ULAR is a feasible option for operable very low rectal cancers and is associated with minimal postoperative events, a low local recurrence and less incidence of LARS.

Abstract
AIM In patients with a previous history of rectal anastomotic leakage (AL), the surgical indications and timing for closure of a diverting stoma have to be carefully judged. Even if AL has apparently healed before stoma closure, re-leakage may occur after closure. The aim of this study was to determine the incidence and risk factors for recurrent AL following stoma closure. We also examined the treatment strategies aiming to minimize the risk of recurrent AL. METHODS From January 2009 to December 2016, 1008 patients underwent sphincter-saving surgery [low anterior resection, all-sphincter-preserving rectal resection with hand-sewn coloanal anastomosis (CAA) and intersphincteric resection (ISR)] for primary rectal cancer with curative intent at our hospital. A total of 69 patients with AL with a Clavien-Dindo Grade III or more who subsequently underwent closure of a diverting stoma were retrospectively reviewed for this study. RESULTS The incidence of recurrent leakage after stoma closure in this series was 13% overall with an incidence of 25% in the CAA/ISR group and 5% in the low anterior resection group. Significant risk factors included hand-sewn anastomosis (P = 0.0257) compared to stapled anastomosis, ischaemia at the anastomotic site as the cause of initial AL (P < 0.001) and a shorter interval between confirmation of healing and stoma closure (P = 0.00952). CONCLUSION Ischaemia at the anastomotic site was the main risk factor for recurrent leakage, particularly after CAA/ISR. Additional treatment options before stoma closure should be considered to avoid re-leakage in such cases.

Abstract
In recent years, rectal MRI has become a central diagnostic tool in rectal cancer staging. Indeed, rectal MR has the ability to accurately evaluate a number of important findings that may impact patient management, including distance of the tumor to the mesorectal fascia, presence of extramural vascular invasion (EMVI), presence of lymph nodes, and involvement of the peritoneum/anterior peritoneal reflection. Many of these findings are difficult to assess in nonexpert hands. In this review, we present a practical approach for radiologists to provide high-quality interpretations at initial baseline exams, based on recent guidelines from the Society of Abdominal Radiology, Rectal and Anal Cancer Disease Focused Panel. Practical pearls and pitfalls are discussed, focusing on optimization of technique including, patient preparation and protocol recommendations, interpretation, and essentials of reporting.

Abstract
Achievement of pathologic complete response (pCR) in patients with locally advanced rectal cancer correlates with improved prognosis relative to non-pCR counterparts. Such correlations are not well established in the context of a community-based hospital. This study aims to examine pCR rates, recurrences, and survival data for locally advanced rectal cancer patients in community settings. A single-center retrospective chart review was performed at a community-based hospital. Study population consisted of 119 patients with locally advanced rectal cancer treated with neo-adjuvant chemoradiotherapy, followed by surgical resection. Patients with a history of metastasis, inflammatory bowel disease, hereditary cancer syndromes, concurrent or prior malignancy, and emergent surgery were excluded. Twenty-four patients (20.2%) achieved pCR. Across both groups, all demographics and perioperative characteristics were comparable. The five-year survival was 73.7 per cent in the non-pCR group and 95.8 per cent in the pCR group ( P = 0.0243). At five years, 27.7 per cent of the non-pCR group had a recurrence, as compared with none in the pCR group ( P = 0.0018). Based on our study, we believe that a multidisciplinary approach to rectal cancer used at a community-based hospital can achieve oncological outcomes and survival benefits similar to those of larger academic tertiary care institutions.
