Abstract
BACKGROUND Fourth-degree perineal tears associated with vaginal delivery (PTAVD) occur in approximately 0.25 to 6% of vaginal deliveries. A persistent challenge in treating fourth-degree PTAVD is the high incidence of anastomotic leakage, leading to impaired quality of life, marked by incontinence, rectovaginal fistula, and painful sexual intercourse. Thus, effective interventions are necessary. Herein, we report our successful approach in repairing a fourth-degree PTAVD, involving the placement of a transanal decompression tube (TDT) during the early postoperative period. CASE PRESENTATION Five patients underwent the repair of fourth-degree PTAVD by suturing the mucosal and muscular layers of the rectum, and the vaginal wall in layers. Subsequently, a TDT was placed in the rectum, positioned 10-15 cm from the anal verge. The TDT was allowed to drain spontaneously without suction. Gastrografin enema examination was performed through a TDT, followed by a computed tomographic scan on postoperative days 3-4. After unfavorable complications were ruled out, the TDT was removed and the patients were transitioned to a normal diet. RESULT All patients showed favorable outcomes with no occurrence of vaginal fistula or incontinence. CONCLUSION This simple intervention demonstrates potential efficacy in reducing anastomotic leakage following the repair of fourth-degree PTAVD.

Advancing mid-rectal cancer surgery: Unveiling the potential of natural orifice specimen extraction surgery in comparison to conventional laparoscopic-assisted resection. Cancer Rep (Hoboken) 2024; 7:e2003. [PMID: 38703000 PMCID: PMC11069103 DOI: 10.1002/cnr2.2003] [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: 10/25/2023] [Revised: 12/28/2023] [Accepted: 02/05/2024] [Indexed: 05/06/2024] Open
Abstract
BACKGROUND Mid-rectal cancer treatment traditionally involves conventional laparoscopic-assisted resection (CLAR). This study aimed to assess the clinical and therapeutic advantages of Natural Orifice Specimen Extraction Surgery (NOSES) over CLAR. AIMS To compare the clinical outcomes, intraoperative metrics, postoperative recovery, complications, and long-term prognosis between NOSES and CLAR groups. MATERIALS & METHODS A total of 136 patients were analyzed, with 92 undergoing CLAR and 44 undergoing NOSES. Clinical outcomes were evaluated, and propensity score matching (PSM) was employed to control potential biases. RESULTS The NOSES group exhibited significant improvements in postoperative recovery, including lower pain scores on days 1, 3, and 5 (p < .001), reduced need for additional analgesics (p = .02), shorter hospital stays (10.8 ± 2.3 vs. 14.2 ± 5.3 days; p < .001), and decreased intraoperative blood loss (48.1 ± 52.7 mL vs. 71.0 ± 55.0 mL; p = .03). Patients undergoing NOSES also reported enhanced satisfaction with postoperative abdominal appearance and better quality of life. Additionally, the NOSES approach resulted in fewer postoperative complications. CONCLUSION While long-term outcomes (overall survival, disease-free survival, and local recurrence rates) were comparable between the two methods, NOSES demonstrated superior postoperative outcomes compared to CLAR in mid-rectal cancer treatment, while maintaining similar long-term oncological safety. These findings suggest that NOSES could serve as an effective alternative to CLAR without compromising long-term results.

Abstract
BACKGROUND AND OBJECTIVES Anastomotic leak following colorectal anastomosis adversely impacts short-term, oncologic, and quality-of-life outcomes. This study aimed to assess the impact of omental pedicled flap (OPF) on anastomotic leak among patients undergoing low anastomotic resection (LAR) for rectal cancer using a multi-institutional database. METHODS Adult rectal cancer patients in the US Rectal Cancer Consortium, who underwent a LAR for stage I-III rectal cancer with or without an OPF were included. Patients with missing data for surgery type and OPF use were excluded from the analysis. The primary outcome was the development of anastomotic leaks. Multivariable logistic regression was used to determine the association. RESULTS A total of 853 patients met the inclusion criteria and OPF was used in 106 (12.4%) patients. There was no difference in age, sex, or tumor stage of patients who underwent OPF versus those who did not. OPF use was not associated with an anastomotic leak (p = 0.82), or operative blood loss (p = 0.54) but was associated with an increase in the operative duration [β = 21.42 (95% confidence interval = 1.16, 41.67) p = 0.04]. CONCLUSIONS Among patients undergoing LAR for rectal cancer, OPF use was associated with an increase in operative duration without any impact on the rate of anastomotic leak.

Abstract
INTRODUCTION Surgical- and nonsurgical complications significantly worsen postoperative outcomes, and identification of patients at risk is crucial to improve care. This study investigated whether comorbidities, graded by the Charlson Comorbidity Index (CCI), impact complication rates and impair long-term outcome in a cohort of left-sided colorectal resections. METHODS Retrospective analysis of patients undergoing oncological left-sided colorectal resections due to colorectal cancer between 01/2015 and 12/2020 in two referral centers in Austria using electronic medical records and national statistical bureau survival data. Patients with recurrent disease, peritoneal carcinomatosis, and emergency surgeries were excluded. Comorbidities were assessed using the CCI, and complication severity was defined by the Clavien-Dindo classification (CDC). Logistic regression analysis was performed to identify factors influencing the risk for postoperative complications, and overall survival was assessed using data from the national statistics bureau. RESULTS A total of 471 patients were analyzed. Multinominal logistic regression analysis identified a CCI greater than or equal to 6 ( P =0.049; OR 1.59, 95% CI: 1.10-2.54) and male sex ( P =0.022; OR 1.47, 95% CI: 1.21-2.98) as independent risk factors for major complications. While patients with a high CCI had the worst postoperative survival rates, perioperative complications only impacted on overall survival in patients with low CCIs, but not in patients with high CCIs. CONCLUSION Although a high CCI is a risk factor for major postoperative complications, the presence of comorbidities should not result in withholding surgery.

Abstract
BACKGROUND Anastomotic leak after restorative surgery for rectal cancer is a major complication and may lead to worse long-term oncological and survival outcomes. OBJECTIVE The purpose of this study was to identify risk factors associated with anastomotic leak and to assess the perioperative and long-term oncological impact of anastomotic leak in our cohort of patients with rectal cancer. DESIGN A retrospective analysis was performed on data from the prospectively maintained Cabrini Monash colorectal neoplasia database. Patients who had undergone rectal cancer resection and subsequently received anastomosis between November 2009 and May 2020 were included in this study. Patient and tumor characteristics, technical risk factors, and short-term and perioperative as well as long-term oncological and survival outcomes were assessed. SETTINGS The study was conducted in 3 tertiary hospitals. PATIENTS A total of 693 patients met the inclusion criteria for this study. MAIN OUTCOME MEASURES Univariate analyses were performed to assess the relationship between anastomotic leak and patient and technical risk factors, as well as perioperative and long-term outcomes. Univariate and multivariate proportional HR models of overall and disease-free survival were calculated. Kaplan-Meier survival analyses assessed disease-free and overall survival. RESULTS Anastomotic leak rate was 3.75%. Males had an increased risk of anastomotic leak, as did patients with hypertension and ischemic heart disease. Patients who experience an anastomotic leak were more likely to require reoperation and hospital readmission and were more likely to experience an inpatient death. Disease-free and overall survival were also negatively impacted by anastomotic leaks. LIMITATIONS This is a retrospective analysis of data from only 3 centers with the usual limitations. However, these effects have been minimized because of the high quality and completeness of the prospective data collection. CONCLUSIONS Anastomotic leaks after restorative surgery negatively affect long-term oncological and survival outcomes for patients with rectal cancer.

Abstract
PURPOSE This study aimed to investigate the effect of placement of double-lumen irrigation-suction tubes (DLIST) on the closure of anastomotic defect (AD) after rectal cancer surgery. METHODS The study was carried out at two centers managed by one surgeon, both adopted the same treatments. Patients with postoperative AD after rectal cancer surgery from January 2011 to June 2020 were eligible and were divided into a passive drainage (PD) group and a DLIST group according to whether the PD, placed in the rectal cancer surgery, had been replaced with the DLIST. The effect of DLIST on the AL was evaluated. RESULT There distributed 76 patients in the DLIST group and 52 in the PD group. A higher closure rate was reported in the DLIST group (46 patients in DLIST group, for a closure rate of 60.5%, and 21 patients in PD group, for a closure rate of 40.4%. HR = 3.05; 95% CI: 1.79-5.19; P < 0.001). Both length of stay and costs of the treatment in the DLIST group were lower (54 days [interquartile range, IQR: 41-17] days vs. 112 days [IQR: 66-27] days, P = 0.005; and $18,721 [IQR: $14,982-4,960] vs. $40,840 [IQR: $20,932-50,529], P < 0.001). CONCLUSION Placement of DLIST might serve as an effective method for treating AD following rectal cancer surgery. In comparison with PD, it costs lower to apply DLIST in the treatment of AD and the length of stay is shorter.

[PMID: 36358002 DOI: 10.1111/ans.18148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 10/30/2022] [Accepted: 10/31/2022] [Indexed: 11/12/2022]
Abstract
BACKGROUND Following ultralow anterior resection for distal rectal cancers, a coloanal anastomosis is usually created along with a defunctioning ileostomy (DI). Recent evidence suggests that abdominoperineal pull-through with delayed coloanal anastomosis (DCAA) is a viable alternative to immediate coloanal anastomosis (ICAA), minimizing the risk of anastomotic leakage and avoiding the need for stoma creation with the risk of stoma-associated morbidity. However, DCAA requires a longer initial hospitalization. We aimed to perform a cost-effectiveness analysis to compare DCAA versus ICAA for elective rectal cancer surgery. METHODS A decision tree model was used to compare the cost-effectiveness of the two strategies. Cost data were obtained from the 2019 to 2020 United Kingdom National Health Service reference costs. Model probabilities were derived from published studies. Univariate and probabilistic sensitivity analyses were used to evaluate the robustness of the results. RESULTS DCAA was the overall cheaper strategy at £13 541 compared with £14 856 for ICAA in the base case analysis. This was explained by the decreased overall costs of hospitalization/surgery, reduction in costs associated with anastomotic or stoma-related complications, specifically dehydration-induced hospital readmissions and avoidance of stoma maintenance costs. Sensitivity analysis demonstrated that DCAA remained consistently more inexpensive except when the duration of total parenteral nutrition exceeded 14 days. CONCLUSION Despite a longer index hospitalization with higher initial costs, this economic analysis demonstrates that DCAA without stoma is overall more cost-effective compared with ICAA with DI following ultralow anterior resection. Cost savings should be considered an additional benefit when selecting the DCAA approach for rectal cancer surgery.

Abstract
Purpose Anastomotic leakage (AL) is a serious postoperative complication that affects short- and long-term outcomes. The use of a trans-anal drainage tube (TDT) is reported to prevent AL in rectal cancer patients, but its value in sigmoid colon cancer patients is unknown. Methods Admitted to the study were 379 patients who underwent surgery for sigmoid colon cancer between 2016 and 2020. Patients were divided into two groups according to the placement (n = 197) or nonplacement of a TDT (n = 182). To determine the factors affecting the association between TDT placement and AL, we estimated average treatment effects by stratifying each factor using the inverse probability of treatment weighting method. The association between prognosis and AL was evaluated in each identified factor. Results Factors associated with postsurgical insertion of a TDT were advanced age, male sex, high body mass index (BMI), poor performance status, and presence of comorbidities. TDT placement was associated with a significantly lower AL in male patients (odds ratio [OR], 0.22; 95% confidence interval [CI], 0.07-0.73; P = .013) and for BMI ≥ 25 kg/m2 (OR, 0.13; 95% CI, 0.02-0.65; P = .013). In addition, there was a significant association of AL with poor prognosis in patients with BMI ≥ 25 kg/m2 (P = .043), age > 75 y (P = .021), and pathological node-positive disease (P = .015). Conclusion Sigmoid colon cancer patients with BMI ≥ 25 kg/m2 are the most appropriate candidates for postoperative TDT insertion, in terms of reduced incidence of AL and improved prognosis.

[PMID: 36567776 PMCID: PMC9750781 DOI: 10.1155/2022/6231880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 10/17/2022] [Accepted: 10/21/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Anastomotic leakage is one of the most serious complications that can occur after laparoscopic-assistedsphincter-preserving surgery for middle- and low-grade rectal cancer. OBJECTIVES To explore the cause, prevention, and treatment of anastomotic leakage after sphincter-preserving surgery for middle- and low-grade rectal cancer under laparoscopy. METHODS The clinical data from patients with mid- and low-grade rectal cancer who underwent laparoscopic-assistedanus-preserving surgery in the anorectal surgery department of our hospital have been analyzed. Patients with a definite diagnosis, indications for laparoscopic surgery, and sphincter-preserving surgery were included in the analysis, and patients with a protective loop ileostomy and laparotomy were excluded. RESULTS Among the 126 patients with middle- and low-grade rectal cancer undergoing sphincter-preserving surgery under laparoscopy. There were 75 male patients and 51 female patients, ranging in age from 37 to 89 years old, with an average age of 60.2 ± 6.7. The distance from the lower edge of the rectal tumor to the anal edge was ≤10 cm. 6 developed anastomotic leakage after the operation (leakage rate of 4.7%). Moreover, turbid purulent fluid was drained from the abdominal drainage tube in three patients on the third and fourth days after the operation, and the abdominal drainage tube drained serous drainage in three more patients on the fifth and sixth days, with signs of peritonitis appearing locally. All patients received continuous flushing and negative pressure drainage with a self-made double cannula and symptomatic treatment, and all were cured and discharged. CONCLUSION Many factors can cause anastomotic leakage after this operation, and adequate perioperative preparation, meticulous operation during surgery, and careful postoperative management are key factors in preventing it.

Abstract
AIM Recent reports have described the use and efficacy of several types of transanal tube (TAT) for preventing anastomotic leakage by reducing intraluminal pressure. The aim of this study was to evaluate the safety and efficacy of a newly developed TAT for the prevention of anastomotic leakage after low anterior resection (LAR) for rectal cancer. METHOD A multicentre confirmatory single-arm trial was designed to evaluate the safety and efficacy of a new TAT after LAR for rectal cancer. A total of 115 patients were registered in the trial at several cancer centres and other hospitals. All patients initially received reconstruction with a stapled anastomosis, but 18 then underwent creation of a diverting stoma. Of the remaining 97 patients, the first 96 were included in the protocol-defined primary analysis set. The primary outcome was the incidence of symptomatic leakage and the secondary endpoint was the incidence of complications associated with use of the TAT. The TAT was placed during LAR without creating a covering stoma and the drain was removed 4 or 5 days postoperatively. RESULTS The rate of symptomatic leakage was 5.2% (95% confidence interval 1.7-11.7), which was significantly lower than the predetermined threshold value of 15.8% (one-sided p-value 0.0013). Only one patient had Grade 3 rectal bleeding that might have been related to use of the TAT. CONCLUSION This nonrandomized study shows that the TAT appears to be safe and results in lower rates of anastomotic leakage in LAR compared with previous studies.

Abstract
Despite the considerable progress in surgical level and imaging examination methods, anastomotic leakage is still the major complication after intestinal surgery with high incidence rate and mortality rate. Moreover, anastomotic leakage has become one of the serious complications threatening the postoperative life safety, prognosis and quality of life. The occurrence of anastomotic leakage involves the changes of a variety of pathophysiological factors, and is affected by intestinal microbiota, inflammation and immune system. Preoperative intestinal preparation will change the type and number of microbial population in the intestine. Intraoperative anastomotic mode and bleeding volume are also closely related to the occurrence of anastomotic leakage. In addition, the occurrence of anastomotic leakage is associated with local recurrence of colorectal cancer after surgery. Intraoperative protective stoma is confirmed to reduce the incidence of anastomotic leakage. Combined preoperative adjustment of nutritional status and inflammatory factors is important for avoiding anastomotic leakage after surgery.

Abstract
AIM The aim was to determine the accuracy of C-reactive protein (CRP), procalcitonin and neutrophils in the early detection (fourth postoperative day) of anastomotic leakage (AL) after colorectal surgery. METHODS We conducted a multicentre, prospective study that included a consecutive series of patients who underwent colorectal resection with anastomosis without ostomy (September 2015 to December 2017). CRP, procalcitonin and neutrophil values on the fourth postoperative day after colorectal resection along with the postoperative outcome (60-day AL, morbidity and mortality) were prospectively included in an online, anonymous database. RESULTS The analysis ultimately included 2501 cases. The overall morbidity and mortality was 30.1% and 1.6%, respectively, and the AL rate was 8.6%. The area under the receiver operating characteristic curve values (95% CI) for detecting AL were 0.84 (0.81-0.87), 0.75 (0.72-0.79) and 0.70 (0.66-0.74) for CRP, procalcitonin and neutrophils, respectively. The best cut-off level for CRP was 119 mg/l, resulting in 70% sensitivity, 81% specificity and 97% negative predictive value. After laparoscopic resection, the accuracy for CRP and procalcitonin was increased, compared with open resection. The combination of two or three of these biomarkers did not significantly increase their accuracy. CONCLUSION On the fourth postoperative day, CRP was the most reliable marker for excluding AL. Its high negative predictive value, especially after laparoscopic resection, allows for safe hospital discharge on the fourth postoperative day. The routine use of procalcitonin or neutrophil counts does not seem to increase the diagnostic accuracy.

Abstract
Background: Robotic colorectal surgery has been increasingly performed in recent years. The safety and feasibility of its application has also been demonstrated worldwide.However, limited studies have presented clinical data for patients with colorectal cancer (CRC) receiving robotic surgery in China. The aim of this study is to present short-term clinical outcomes of robotic surgery and further confirm its safety and feasibility in Chinese CRC patients. Methods: The clinical data of 109 consecutive CRC patients who received robotic surgery at Sun Yat-sen University Cancer Center between June 2016 and May 2019 were retrospectively reviewed. Patient characteristics,tumor traits, treatment details, complications, pathological details, and survival status were evaluated. Results: Among the 109 patients, 35 (32.1%) had sigmoid cancer, and 74 (67.9%) had rectal cancer. Thirty-seven (33.9%) patients underwent neoadjuvant chemoradiotherapy. Ten (9.2%) patients underwent sigmoidectomy, 38 (34.9%) underwent high anterior resection (HAR), 45 (41.3%) underwent low anterior resection (LAR), and 16 (14.7%) underwent abdominoperineal resection (APR). The median surgical procedure time was 270 min (range 120–465 min). Pathologically complete resection was achieved in all patients. There was no postoperative mortality. Complications occurred in 11 (10.1%) patients, including 3 (2.8%) anastomotic leakage, 1 (0.9%) anastomotic bleeding, 1 (0.9%) pelvic hemorrhage, 4 (3.7%) intestinal obstruction, 2 (1.8%) chylous leakage, and 1 (0.9%) delayed wound union. At a median follow-up of 17 months (range 1–37 months), 1 (0.9%) patient developed local recurrence and 5 (4.6%) developed distant metastasis, with one death due to disease progression. Conclusions: Our results suggest that robotic surgery is technically feasible and safe for Chinese CRC patients, especially for rectal cancer patients who received neoadjuvant treatment. A robotic laparoscope with large magnification showed a clear surgical space for pelvic autonomic nerve preservation in cases of mesorectal edema.

Abstract
PURPOSE Anastomotic leak (AL) following colorectal cancer resection is associated with considerable morbidity and mortality with an impact on recurrence rates and survival. The impact of obesity on AL rates is debated. This meta-analysis aims to investigate the relationship between obesity and AL. METHODS A search was conducted of the PubMed/MEDLINE, and Web of Science databases and included studies were split into Western and Asian groups based on population-specific body mass index (BMI) ranges for obesity. A meta-analysis was performed to assess the impact of obesity on AL rate following colorectal cancer resection. RESULTS Two thousand three hundred and four articles were initially screened. Thirty-one studies totaling 32,953 patients were included. Patients with obesity had a statistically significant increase in AL rate in all Western and Asian study groups. However, this increase was only clinically significant in the rectal anastomotic subgroups-Western: 10.8% vs 8.4%, OR 1.57 (1.01-2.44) and Asian: 9.4% vs 7.4%, OR 1.58 (1.07-2.32). CONCLUSIONS The findings of this analysis confirm that obesity is a significant risk factor for anastomotic leak, particularly in rectal anastomoses. This effect is thought to be primarily mediated via technical difficulties of surgery although metabolic and immunological factors may also play a role. Obesity in patients undergoing restorative CRC resection should be discussed and considered as part of the pre-operative counselling.

Abstract
BACKGROUND Intra-abdominal infection after curative surgery for colorectal cancer is a serious complication associated with an increased risk of recurrence. Lipopolysaccharides (LPS)-an essential component of the cell wall of Gram-negative bacteria-were found to exert a protumorigenic effect by stimulating the inflammatory pathology and formation of neutrophil extracellular traps (NETs). This study was conducted to test whether LPS-induced formation of NETs promotes the development of cancer and metastasis. METHODS The clinical characteristics, incidence of relapse, and serum myeloperoxidase-DNA complexes of 40 patients with infection and 40 patients without infection after curative surgery were analyzed. The effects of LPS on the induction of NETs were evaluated in a mouse model of colorectal cancer and liver metastasis. The toll-like receptor 9 (TLR9)-a DNA receptor-was knocked down to assess its effect on the mitogen-activated protein kinase pathway and activities implicated in the formation of NETs. RESULTS Analysis of the clinical data obtained from these patients showed the significant relation of the formation of NETs and incidence of metastasis and survival rates. Subsequent in vitro experiments revealed an increased level of citrullinated-histone H3 and myeloperoxidase-DNA in LPS-injected mice with colorectal cancer. In the mimic metastatic model, injection of LPS enhanced the metastatic capacity, which was then attenuated by DNase I. This suggested that the formation of NETs was activated by LPS. Injection of TLR9-knockdown HCT116 cells in mice, followed by induction through LPS, mitigated the level of citrullinated-histone H3 and myeloperoxidase-DNA. This finding implied that the formation of NETs was suppressed. CONCLUSION These findings shed light on the mechanism underlying the relationship between the elevated rate of colorectal cancer recurrence in patients who underwent surgery and the incidence of infection. This mechanism involves the protumorigenic activities of LPS-induced formation of NETs. The NETs which could be mediated by the TLR9 and the mitogen-activated protein kinase signaling pathway.

Abstract
Dehiscence of colorectal anastomosis is a serious complication that is associated with increased mortality, impaired functional and oncological outcomes. The hypothesis was that anastomosis reinforcement and vacuum trans-anal drainage could eliminate some risk factors, such as mechanically stapled anastomosis instability and local infection. Patients with rectal cancer within 10 cm of the anal verge and low anterior resection with double-stapled technique were included consecutively. A stapler anastomosis was supplemented by trans-anal reinforcement and vacuum drainage using a povidone-iodine-soaked sponge. Modified reinforcement using a circular mucosa plication was developed and used. Patients were followed up by postoperative endoscopy and outcomes were acute leak rate, morbidity, and diversion rate. The procedure was successfully completed in 52 from 54 patients during time period January 2019–October 2020. The mean age of patients was 61 years (lower–upper quartiles 54–69 years). There were 38/52 (73%) males and 14/52 (27%) females; the neoadjuvant radiotherapy was indicated in a group of patients in 24/52 (46%). The mean level of anastomosis was 3.8 cm (lower–upper quartiles 3.00–4.88 cm). The overall morbidity was 32.6% (17/52) and Clavien–Dindo complications ≥ 3 grade appeared in 3/52 (5.7%) patients. No loss of anastomosis was recorded and no patient died postoperatively. The symptomatic anastomotic leak was recorded in 2 (3.8%) patients and asymptomatic blind fistula was recorded in one patient 1/52 (1.9%). Diversion ileostomy was created in 1/52 patient (1.9%). Reinforcement of double-stapled anastomosis using a circular mucosa plication with combination of vacuum povidone-iodine-soaked sponge drainage led to a low acute leak and diversion rate. This pilot study requires further investigation. Registered at ClinicalTrials.gov.: Trial registration number is NCT04735107, date of registration February 2, 2021, registered retrospectively.

Surgery 2021; 170:397-404. [PMID: 33541747 DOI: 10.1016/j.surg.2020.12.030] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 12/17/2020] [Accepted: 12/23/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND Numerous randomized controlled trials comparing end-to-end and end-to-side anastomoses after low anterior resection have been performed. Rates of anastomotic leakage and overall postoperative morbidity, as well as reported quality of postoperative bowel function, vary across individual studies. As such, this study meta-analyzes pooled data comparing end-to-end and end-to-side anastomosis after low anterior resection in terms of anastomotic leak rate and postoperative bowel function. METHODS A search of Medline, EMBASE, and Cochrane Central Register of Controlled Trials was performed. Articles were included if they were randomized controlled trials that compared end-to-end and end-to-side anastomosis after low anterior resection for benign or malignant disease. The primary outcome was anastomotic leak rate. A pairwise meta-analysis was performed using inverse variance random effects. RESULTS From 1,452 citations, 6 randomized controlled trials with 270 patients undergoing end-to-end anastomosis (45.9% female, mean age: 63.5 years) and 268 patients undergoing end-to-side anastomosis (52.4% female, mean age: 64.0 years) met inclusion criteria. Patients undergoing end-to-side anastomosis had a significantly lower rate of anastomotic leak (RR 0.37, 95% CI 0.15-0.93, P = .04, I2=0%). There were no differences in rate of anastomotic stenosis (RR 1.03, 95% CI 0.21-5.19, P = .97) or overall postoperative morbidity (RR 0.60, 95% CI 0.33-1.07, P = .08). Narrative review of postoperative bowel function demonstrated evidence of improved Wexner scores for 6 months postoperatively in patients undergoing end-to-side anastomosis. CONCLUSION End-to-side anastomosis significantly reduces the risk of anastomotic leak after low anterior resection. Additional prospective trials are warranted to confirm the findings of this review and to contribute to the growing evidence-base aimed at optimization of bowel function after low anterior resection.

Abstract
BACKGROUND Anastomotic leaks are a dreaded complication after colorectal surgery. Although anastomotic leak is often used as a metric to compare patient outcomes, a standard definition does not exist. MATERIALS AND METHODS A web-based survey was developed and distributed to US surgeons. Respondents were queried on the definition of anastomotic leaks using a 5-point Likert scale to rate different scenarios related to colorectal surgery. RESULTS Of potential 2209 respondents, 649 (29%) responded to the survey. The majority of respondents was men (76%) and practiced colon and rectal surgery as their primary specialty (89%). Contrast extravasation at the anastomosis, regardless of timing related to the surgery, is the clinical scenario with greatest consensus (>85%). 50% of surgeons do not believe that an abscess near the anastomosis in an asymptomatic patient defines a leak. CONCLUSIONS These results highlight the pressing need for standardization of the anastomotic leak definition given the implications on outcomes measurement, research trials, and health care reimbursement.

Intraoperative Thermal Imaging for Evaluating Blood Perfusion During Laparoscopic Colorectal Surgery. Surg Laparosc Endosc Percutan Tech 2020; 31:281-284. [PMID: 33347089 DOI: 10.1097/sle.0000000000000893] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Accepted: 10/05/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Anastomotic leakage is a feared complication of anterior resection for rectal cancer. Among the various factors reported to be involved in the occurrence of anastomotic leakage, blood perfusion of the remnant intestine is one of the most important. Recently, the usefulness of evaluating blood perfusion using indocyanine green (ICG) has been reported. We therefore aimed to show that measuring intestinal temperature using thermography is useful for evaluating blood perfusion. The authors also investigated the relation between intestinal temperatures and the ICG fluorescence time (FT). MATERIALS AND METHODS Altogether, 45 patients who underwent laparoscopic anterior resection for rectal cancer between July 2017 and September 2018 were enrolled in this study. ICG FT and intestinal temperature were measured after the mesenteric dissection. RESULT The temperature boundary could be easily identified using thermographic images. The temperature of the residual intestinal tract was significantly higher than that of the resected intestinal tract at the planned separation line (29.9 vs. 27.3°C). In addition, there was an inverse correlation between the ICG FT and the temperature of the residual intestine. CONCLUSION Intestinal temperature measurement through thermography is a useful new tool for evaluating intestinal blood perfusion.

Abstract
Although surgeries involving anastomosis are relatively common, anastomotic leakages are potentially deadly complications of colorectal surgeries due to increased risk of morbidity and mortality. As a result of the potentially fatal effects of anastomotic leakages, a myriad of techniques and treatments have been developed to treat these unfortunate cases. In order to better understand the steps taken to treat this complication, we have created a composite review involving some of the current and best treatments for colonic anastomotic leakage that are available. The aim of this article is to present a background review of colonic anastomotic leakage, as well as current strategies to prevent and treat this condition, for a broader audience, including scientist, engineers, and especially biomedical engineers.

Abstract
PURPOSE The usage of indocyanine green (ICG) dye is commonly associated with decreased anastomotic leakage rates in colectomies. This study aims to perform a network meta-analysis to assess the usage of ICG fluorescence imaging in right-sided colectomies. METHODS Medline, Embase, Cochrane Trials, CNKI, and WanFang electronic databases were reviewed, and meta-analysis of proportions, comparative meta-analysis, and network meta-analysis were conducted in this review. Studies comparing ICG usage with conventional approaches of anastomosis were selected, with postoperative anastomotic leak rate being the primary outcome. RESULTS Ten articles were included, with a total of 675 patients involved, of which 515 patients underwent colorectal surgery with ICG. Anastomotic leak rates with ICG were estimated to be 1% (CI 0.00-0.04) and 3% (CI 0.01-0.06) for right and left procedures, respectively. No significant difference was observed in left-sided colectomies (OR 0.587; 95% CI 0.218-1.582; p = 0.292). There were nearly half the odds of anastomotic leakage when ICG was used in right-sided colectomies (OR 0.524; 95% CI 0.128-2.137). CONCLUSION With the ability to potentially avert postoperative anastomotic leakage, coupled with its minimal costs and side effects, administration of ICG in colectomies in centers where equipment is available should be encouraged.

A double-lumen irrigation-suction tube placed during operation could reduce the risk of grade C anastomotic leakage resulting from selective sigmoid colon cancer radical resection. Langenbecks Arch Surg 2020; 405:1007-1016.

Abstract
AIM This study investigated the effect of a double-lumen irrigation-suction tube in reducing the incidence of grade C anastomotic leakage (AL) resulting from a selective sigmoid colon cancer radical resection. METHOD This multicenter retrospective cohort study reviewed data of patients receiving sigmoid colon cancer radical resection from January 2010 to November 2019. The enrolled patients were divided into the passive drainage tube group and the double-lumen irrigation-suction tube group, based on the use of a double-lumen irrigation-suction tube or a passive drainage tube during the surgery. The effect of double-lumen irrigation-suction tube on the incidence of grade C anastomotic leakage was evaluated. RESULTS Of the 761 patients included in the study, 56 patients (7.36%) experienced AL. Of the 56 patients, 22 were diagnosed with grade C AL. The double-lumen irrigation-suction tube was a protective factor for forming a grade C AL compared with the passive drainage tube (OR = 0.194, 95% CI: 0.055-0.686, p = 0.011). Of the 34 patients with grade A or B AL, 26 patients had spontaneous closure-19 in the double-lumen irrigation-suction tube group and 7 in the passive drainage tube group. The double-lumen irrigation-suction tube (multivariable HR = 3.418, 95% CI: 1.43-11.203, p = 0.038) was associated with spontaneous closure of grade A or B AL. CONCLUSION Placing a double-lumen irrigation-suction tube may reduce the risk of grade C AL resulting from a selective sigmoid colon cancer radical resection. However, this study had substantial selection bias and the results should be reconfirmed by a randomized clinical trial.

Abstract
Introduction A proactive approach is recommended in colorectal anastomosis leak treatment, and early diagnosis is very important. Early postoperative endoscopy would allow rapid diagnosis of anastomotic pathologies and consequent prompt intervention according to anastomotic disruption morphology. Aim To evaluate the effectiveness of close endoscopic follow-up of all patients (including asymptomatic ones) in improving diagnosis of acute leak (AL) and reducing its complications. Material and methods This study included 124 patients who had undergone rectum resection for rectal cancer with stapled anastomosis. Endoscopy was performed between the 7th and 10th postoperative day and 1 month postoperatively. For defect morphology assessment, a classification system was created based on four levels of severity. Photographic findings were evaluated by an independent, experienced gastroenterologist. Results Postoperative endoscopy revealed 28 (22.6%) patients with acute leakage. Initial endoscopy confirmed AL in 18 patients. Six (31.6%) patients were asymptomatic and 13 (68.4%) were symptomatic. The second endoscopy revealed another 9 (32.1%) leaks (4 (44.5%) asymptomatic and 5 (55.5%) symptomatic). Sixteen (57.1%) patients had grade A leakages, 7 (25.0%) had grade B leakages, and 5 (17.9%) had grade C leakages. Furthermore, 22 of 27 (81%) defects were located posterior and posterior-laterally. Fifteen (55.5%) defects were smaller than 1/3 the circumference, 7 (25.9%) affected 1/3–1/2 of the circumference, and 5 (18.5%) affected more than 1/2 of the circumference. Conclusions Incorporation of early endoscopy in postoperative management allows rapid diagnosis of AL and allows faster intervention, even in leaks that are clinically silent.

Abstract
INTRODUCTION Anastomotic leakage (AL) after low anterior resection for rectal cancer is a severe complication. Except for re-operation, several endoscopic options have been proposed for the minimal invasive treatment of AL, including the endoluminal vacuum devices, tissue sealants and Over-The-Scope-Clip (OTSC) technique. The aim of the present review is to evaluate the effect of alternative treatment options for AL repair, by means of endoscopy. METHOD A bibliographic search was performed in the international literature. Ten case reports and series were finally included, reporting 75 cases of endoscopic repair of AL. A descriptive statistical analysis and a systematic review were performed. RESULTS The patients' mean age was 65.84 ± 9.92 years (95% CI: 61.70-68.76), the male-to-female ratio being 1.5:1. The mean diameter of the cavity was 5.17 ± 3.32 cm (95% CI: 4.03-6.31). The mean time until the diagnosis was 44.15 ± 105.91 days (95% CI: 13.39-74.90). Vacuum-assisted closure therapy was the most common technique (52%), followed by fibrin glue (25.3%) and OTSC (22.7%). As supplementary therapy, OTSC was applied in 8.3%, vacuum-assisted closure in 25%, endoclips in 4.2%, while fibrin glue was the most frequently used (62.5%). CONCLUSION Endoscopic management of AL after low anterior resection is considered as an alternative to surgical treatment with promising results.

Abstract
Introduction
Anastomotic leakage (AL) is generally accepted as a major complication of rectal resection surgery. However, there is still debate about the definition and evaluation of AL. The International Study Group of Rectal Cancer (ISREC) raised a definition of and grading system for AL in 2010.
Aim
In our study, we aimed to validate AL's present definition and grading system, which were proposed by ISREC in 2010.
Methods
Patients who underwent rectal anterior resection in 2 colorectal surgery centers from January 2012 to December 2014 were included and categorized into different groups according to the ISREC criteria; further, the rate, severity and clinical outcomes of their ALs were analyzed and compared.
Results
During a median follow-up period of 38.9 months, 984 patients were included in total. The overall AL rate was 5.0% (49/984), including 7 grade A patients (14%), 21 grade B patients (43%), and 21 grade C patients (43%). The rate of grade C AL in the protective diverting stoma group was significantly lower than that in the nonstoma group (0.6% versus 2.8%, P = 0.029). Patients with grade B or grade C AL had much longer hospital stays than grade A AL patients (P = 0.016). The overall 3-year survival rates of grades A, B, and C groups were 83.3%, 66.7% and 55.6% respectively, without statistical significance.
Conclusions
Patients who were divided into different groups according to the grading system proposed by the ISREC criteria had significantly different symptoms, clinical outcomes, management, and duration of hospitalization. Our study supported that the ISREC criteria are a simple but valid classification to evaluate the surgical performance of the rectal cancer resection.

Abstract
PURPOSE OF REVIEW To identify and discuss emerging trends in the therapeutic use of hyperbaric oxygen. RECENT FINDINGS There has been a maturing of the clinical evidence to support the treatment of sudden hearing loss, a wide range of problematic chronic wound states and the prevention and treatment of end-organ damage associated with diabetes mellitus. On the other hand, the controversy continues concerning the use of hyperbaric oxygen therapy (HBOT) to treat sequelae of mild traumatic brain injury. HBOT remains poorly understood by many medical practitioners despite more than 50 years of clinical practice. Pharmacological actions arise from increased pressures of oxygen in the blood and tissues. Most therapeutic mechanisms identified are not the simple result of the reoxygenation of hypoxic tissue, but specific effects on immunological and metabolic pathways by this highly reactive element. HBOT remains controversial despite biological plausibility and a solid clinical evidence base in several disease states. SUMMARY Multiple proposals for new indications for HBOT continue to emerge. Although many of these will likely prove of limited clinical importance, some show significant promise. Responsible practitioners remain acutely aware of the need for high-quality clinical evidence before introducing emerging indications into routine practice.

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
BACKGROUND Despite implementation of enhanced recovery after surgery (ERAS) and laparoscopic techniques, postoperative ileus (POI) remains frequent after colorectal surgery, impacting the patient, their recovery and health-care resources. Presently there are no tests that reliably predict or enable early POI diagnosis. Volatile organic compounds (VC) are products of human and microbiota cellular metabolism and we hypothesised that a detectable alteration occurs in POI. METHOD This was a prospective observational study of patients undergoing laparoscopic colorectal resection within an established ERAS programme. Standardized end-expiratory breath sampling was performed on the morning of surgery and on the first three postoperative mornings. The concentrations of VCs commonly found in intestinal gas were analysed using selected ion flow tube mass spectrometry and GastroCH4 ECK®. Feasibility data, bowel preparation, postoperative oral intake, POI and 30-day morbidity were recorded. RESULTS Of the 75 potentially eligible patients, 58 (77%) agreed to participate. Per-protocol breath sampling was successfully completed in 94%. There were no analytical failures. Baseline and postoperative concentrations of VCs were broadly comparable and were not altered by bowel preparation or postoperative oral intake. POI developed in 14 (29%) patients. Preoperative ammonia concentration was higher in patients who developed POI [830 parts per billion (ppb) vs 510 ppb, P = 0.027]. There was an increase in the concentration of acetic acid detected on day 2 in patients who developed POI (99 ppb vs 171 ppb, P = 0.021). CONCLUSION Repeated VC breath sampling and analysis is feasible in the perioperative setting. An elevated ammonia concentration on the morning of surgery may be a potential predictor of POI.

Adipose tissue grafting for management of persistent anastomotic leak after low anterior resection. Tech Coloproctol 2019; 23:981-985.

Abstract
BACKGROUND An anastomotic leak is the most dreaded complication after low anterior resection. Adipose tissue grafting may induce healing in a persistent anastomotic defect. The aim of the present study was to report retrospectively reviewed outcomes for a series of patients who were managed with heterotopic grafted adipose tissue to facilitate anastomotic healing. METHODS Patients with anastomotic leakage after low anterior resection sequentially treated with grafting of adipose tissue were included in the study. All patients had pelvic radiation during treatment and had a diverting ileostomy in situ. The cohort had a persistent defect despite being treated with available modalities such as suture repair, fibrin glue, Endo-Sponge and surgical debridement. The outcomes were reviewed and reported. RESULTS There were 11 patients (8 males and 3 females) with a median age of 54 years (range 33-72 years). Five patients experienced complete healing of the anastomotic defect with successful reversal of the diverting ileostomy. The anastomotic defect of one other patient in the series appeared to have healed and hence his diverting ileostomy was reversed. However, he presented with a recurrent leak, which ultimately necessitated an abdominoperineal resection. Another patient had a persistent defect after an attempt at adipose tissue grafting and opted to proceed with a takedown of the anastomosis. In the remaining four patients, the outcome after adipose tissue grafting remains unknown, as two patients succumbed to metastatic disease, one was lost to follow-up and the remaining patient developed a recurrence which required pelvic exenteration. Procedural associated morbidity occurred in one patient who developed fat embolism, which was treated expectantly. CONCLUSIONS Adipose tissue grafting is safe and feasible, though its effectiveness remains uncertain. It may be useful selectively in the management of persistent anastomotic leak after radiation and low anterior resection.

Abstract
Purpose. Clinically apparent anastomotic leakage (AL) after low anterior rectal resection (LAR; <7 cm from anal verge) using circular double-stapled anastomosis without defunctioning stoma is up to 37.5%. However, it is unclear whether there is reduction of LAR after 21 postoperative days without defunctioning stoma but with extraluminal anastomotic application of fibrin sealant. Methods. Forty-eight-week-old pigs underwent LAR and circular double-stapled anastomosis in end-to-end technique (descendo-rectostomy). Animals were randomized into therapy and control group (cg). Therapy group (n = 20) received additional extraluminal circular anastomotic application of fibrin sealant. Objective was to assess incidence of clinically apparent and nonclinically apparent leakage through the 21st postoperative day. Remaining animals were sacrificed on the 21st day, and anastomotic region was analyzed. In case of earlier diagnosed AL, animals were sacrificed. Results. In cg, we observed clinically and nonclinically AL in 20% (n = 4). No animal was identified with a nonclinical-apparent leakage in this group, and all 4 animals with leakages presented clinical signs. In the therapy group, no animal (0/20) developed clinically apparent leakage signs. There were no leakages in this group, but 3 animals had ulcerative lesions without leak and without clinical signs. These lesions were observed intraluminally at crossing of staple lines after 21 days. In one of these animals, incomplete leakage was observed, blocked by fibrin sealant. Conclusion. In circular stapled colorectal anastomosis, circular fibrin glue sealant successfully protected anastomotic intraluminal wall defects at crossing of staple lines, reducing leakage rate from 20% to 0% (cg vs therapy group) after 21 postoperative days.

The Clinical and Economic Burden of Colorectal Anastomotic Leaks: Middle-Income Country Perspective. Gastroenterol Res Pract 2019; 2019:2879049. [PMID: 31065261 PMCID: PMC6466886 DOI: 10.1155/2019/2879049] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Revised: 02/08/2019] [Accepted: 02/26/2019] [Indexed: 12/15/2022] Open
Abstract
Purpose Anastomotic leaks (AL) present a significant source of clinical and economic burden on patients undergoing colorectal surgeries. This study was aimed at evaluating the clinical and economic consequences of AL and its risk factors. Methods A retrospective cohort study was conducted between 2012 and 2013 based on the billing information of 337 patients who underwent low anterior resection (LAR). The outcomes evaluated were the development of AL, use of antibiotics, 30-day readmission and mortality, and total hospital costs, including readmissions and length of stay (LOS). The risk factors for AL, as well as the relationship between AL and clinical outcomes, were analyzed using multivariable Poisson regression. Generalized linear models (GLM) were employed to evaluate the association between AL and continuous outcomes (LOS and costs). Results AL was detected in 6.8% of the patients. Emergency surgery (aRR 2.56; 95% CI: 1.15-5.71, p = 0.021), blood transfusion (aRR 4.44; 95% CI: 1.86-10.64, p = 0.001), and cancer diagnosis (aRR 2.51; 95% CI: 1.27-4.98, p = 0.008) were found to be independent predictors of AL. Patients with AL showed higher antibiotic usage (aRR 1.69; 95% CI: 1.37-2.09, p < 0.001), 30-day readmission (aRR 3.34; 95% CI: 1.53-7.32, p = 0.003) and mortality (aRR 13.49; 95% CI: 4.10-44.35, p < 0.001), and longer LOS (39.6 days, as opposed to 7.5 days for patients without AL, p < 0.001). Total hospital costs amounted to R$210,105 for patients with AL in comparison with R$34,270 for patients without AL (p < 0.001). In multivariable GLM, the total hospital costs for AL patients were 4.66 (95% CI: 3.38-6.23, p < 0.001) times higher than those for patients without AL. Conclusions AL leads to worse clinical outcomes and increases hospital costs by 4.66 times. The risk factors for AL were found to be emergency surgery, blood transfusion, and cancer diagnosis.

Abstract
BACKGROUND AND AIMS The International Study Group of Rectal Cancer has proposed that a pelvic abscess in the proximity of the anastomosis is considered an anastomotic leak, whether or not its point of origin is detectable. This study describes how the inclusion of pelvic abscesses alters the leakage rate. MATERIAL AND METHODS Risk factors and postoperative complications in patients with visible anastomotic leakage ("direct leakage"), pelvic abscesses alone in the vicinity of a visibly intact anastomosis ("abscess leakage"), and no leakage were retrospectively evaluated. RESULTS In total, 341 patients operated with anterior resections and who received an anastomosis within 15 cm as measured from the anal verge were included. A total of 37 patients (10.9%) had direct leakage, 13 (3.8%) had abscess leakage, and 291 (85.3%) had no leakage. The overall anastomotic leakage rate was 14.7% (50 patients). In accordance with the grading system outlined by International Study Group of Rectal Cancer, 7 patients (2.1%) experienced Grade A leakage, 19 (5.6%) Grade B, and 24 (7.0%) Grade C. Direct leak patients had more often a reoperation due to anastomotic complications (odds ratio = 19.7, p = 0.001), a permanent stoma (odds ratio = 28.5, p = 0.001), and a longer hospital stay than abscess leak patients (29.0 vs 15.5 days, p = 0.030). CONCLUSION Abscess leakage accounted for over one-fourth of the overall leakage rate, raising the leakage rate. Direct leak patients were at a higher risk of requiring a reoperation, permanent stoma, and longer hospital stay than abscess leak patients. Abscess leak patients were at a greater risk for a urinary tract infection, wound infection, and postoperative intestinal obstruction than non-leak patients.

Abstract
INTRODUCTION Currently, there is growing interest in analyzing the results from surgical units and the implementation of quality standards in order to identify good healthcare practices. Due to this fact, the Spanish Association of Coloproctology (AECP) has developed a unit accreditation program that contemplates basic standards. The aim of this article is to evaluate and analyze the specific quality indicators for the surgical treatment of colorectal cancer, established by the program. Data were collected from colorectal units during the accreditation process. METHODS We analyzed prospectively collected data from elective colorectal surgeries at 18 Spanish coloproctology units during the period 2013-2017. Three main and four secondary quality indicators were considered. Colon and rectal surgeries were analyzed independently; furthermore, results were compared according to surgical approach. RESULTS A total of 3090 patients were included in the analysis. The global anastomotic leak rate was 7.8% (6.6% colon vs 10.6% rectum), while the surgical site infection rate was 12.6% (11.4% colon vs 14.8% rectum). Overall 30-day mortality was 2.3%, and anastomotic leak-related mortality was 10.2%. There were higher surgical site infection and mortality rates in the patients operated by open approach, however there was no difference in the anastomotic leak rate when compared with minimally invasive approaches. CONCLUSIONS The evaluation of these results has determined optimal quality indices for the units accredited in the treatment of colorectal cancer. Furthermore, it allows us to establish realistic references in our country, thereby providing a better understanding and comparison of outcomes.

Abstract
INTRODUCTION Rectal cancer surgery with neoadjuvant therapy is associated with substantial morbidity. The present study describes the course of quality of life (QOL) in rectal cancer patients in the first 2 years after the start of treatment. PATIENTS AND METHODS We performed a prospective study within a colorectal cancer cohort including rectal cancer patients who were referred for neoadjuvant chemoradiation or short-course radiotherapy and underwent rectal surgery. QOL was assessed using the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and colorectal cancer questionnaire (EORTC QLQ-CR29) before treatment and after 3, 6, 12, 18, and 24 months. The outcomes were compared with the QOL scores from the Dutch general population and stratified by low anterior resection and abdominoperineal resection. Postoperative bowel dysfunction after low anterior resection was measured using the low anterior resection syndrome score. RESULTS Of the 324 patients, 272 (84%) responded to at least 2 questionnaires and were included in the present study. Compared with pretreatment levels, the strongest decline was observed in physical, role, and social functioning at 3 and 6 months after the start of treatment. Global health and cognitive functioning declined to a lesser extend, and emotional functioning gradually improved over the time. Within 24 months, the QOL scores had recovered toward the pretreatment levels in most patients. Compared with the general population, physical, role, social, and cognitive functioning and symptoms of fatigue and insomnia remained significantly worse in patients on longer-term. After low anterior resection, major bowel dysfunction was reported by 44% to 60% of the patients. Increasing urinary incontinence and severe complaints of impotence were observed in patients who had undergone abdominoperineal resection. CONCLUSION Rectal cancer treatment is associated with a significant decline in QOL during the first 6 months after the diagnosis. Within 2 years, most patients return toward pretreatment functioning but could still experience poorer functioning and treatment-related symptoms compared with the general population. These findings support shared decision-making and emphasize the need for postoperative supportive care and novel treatment approaches.

Abstract
BACKGROUND In sigmoid cancer, both inferior mesenteric artery high or low ligations are accepted for curative purposes. Since inferior mesenteric artery ligation could compromise blood flow to the anastomosis, potentially increasing anastomotic leakage onset, real oncological benefits and possible disadvantages related to vascular transection level are still on debate. We introduce totally laparoscopic inferior mesenteric artery peeling technique to release from the concept of lymph nodal harvesting linked to arterial transection level. METHODS Over a period of 24 months, 31 patients presenting with sigmoid cancer were submitted to laparoscopic sigmoidectomy associated with inferior mesenteric artery peeling. Data on intraoperative and postoperative outcomes have been prospectively collected. RESULTS Mean operative time was 180 min (range 110-330 min); mean intraoperative blood loss was 60 ml (range 30-150 ml), and mean postoperative hospitalization was 6.2 days (range 4-11 days). Mean number of lymph node harvested was 16.7 (range 12-28). CONCLUSIONS Given a proper selection of patients, laparoscopic sigmoidectomy comprehensive of sub-adventitial IMA skeletonization from its aortic origin could provide good oncological outcomes and recanalization rate. Further data are advocated to confirm these preliminary results.

Abstract
AIM To determine the level of consensus on the definition of colorectal anastomotic leakage (CAL) among Dutch and Chinese colorectal surgeons.
METHODS Dutch and Chinese colorectal surgeons were asked to partake in an online questionnaire. Consensus in the online questionnaire was defined as > 80% agreement between respondents on various statements regarding a general definition of CAL, and regarding clinical and radiological diagnosis of the complication.
RESULTS Fifty-nine Dutch and 202 Chinese dedicated colorectal surgeons participated in the online survey. Consensus was found on only one of the proposed elements of a general definition of CAL in both countries: ‘extravasation of contrast medium after rectal enema on a CT scan’. Another two were found relevant according to Dutch surgeons: ‘necrosis of the anastomosis found during reoperation’, and ‘a radiological collection treated with percutaneous drainage’. No consensus was found for all other proposed elements that may be included in a general definition.
CONCLUSION There is no universally accepted definition of CAL in the Netherlands and China. Diagnosis of CAL based on clinical manifestations remains a point of discussion in both countries. Dutch surgeons are more likely to report ‘subclinical’ leaks as CAL, which partly explains the higher reported Dutch CAL rates.

Abstract
AIMS Low anterior resection (LAR) has higher risk of anastomotic leak with its attendant morbidity -mortality. De-functioning loop ileostomy (DLI), claimed to mitigate the consequences of anastomotic leak, has been questioned in recent years. This study aims to evaluate the impact of ileostomy on LAR. METHODS A retrospective analysis of stoma database. 136 patients with stoma (March 2011-July 2015) were assessed. Data was analysed in respect to LAR anastomotic leak rate, impact on morbidity-mortality, short and long-term stoma complications, rate of ileostomy reversal and reasons for non-reversal. RESULTS 45 patients had loop ileostomy for LAR. Male (28) to female (17) ratio was 1.65:1 with median age of 69 (IQR: 56-75.5). Only 3 anastomotic leaks (3/45, 6.5%) occurred, all treated conservatively with no mortality. 29 had reversal, average reversal time is 10 months (3-24) and 5 awaiting. Reasons for non-reversal included patients' choice (7), death from cardiac cause (1), chemotherapy (1), unfit for surgery (1) and failed reversal (1). Acute complications included high output & reversible AKI (1), bleeding (3) and minor complications (6) as skin excoriation, separation and appliance issues. Parastomal hernia was repaired during reversal (12/15). CONCLUSIONS De-functioning ileostomy for LAR is a safe procedure with low morbidity. Most stomas are reversible. Series highlights a late reversal contrary to the nationally recommended guidelines. Most interestingly, the study demonstrated de-functioning mitigated clinical consequences of anastomotic leak to an extent that reoperation was avoidable, in keeping with recent meta-analysis indicating a significantly low anastomotic leakage rates and reoperation. Larger study is invaluable to substantiate findings.

Abstract
BACKGROUND Anastomotic leakage is a severe complication after low anterior resection for rectal cancer. With a global increase in registration initiatives, adapting uniform definitions and grading systems is highly relevant. OBJECTIVE This study aimed to provide clinical parameters to categorize anastomotic leakage into subcategories according to the International Study Group of Rectal Cancer. DESIGN All of the patients who underwent a low anterior resection in the Netherlands with primary anastomosis were included using the population-based Dutch Surgical Colorectal Audit. SETTINGS Data were derived from the Dutch Surgical Colorectal Audit. MAIN OUTCOME MEASURES The development of grade B anastomotic leakage (requiring invasive treatment but no surgery) versus grade C anastomotic leakage (requiring reoperation) was measured. RESULTS Overall, 4287 patients underwent low anterior resection with primary anastomosis. A total of 159 patients (4%) were diagnosed with grade B anastomotic leakage versus 259 (6%) with grade C. Hospital stay and intensive care unit visits were significantly higher in patients with grade C anastomotic leakage compared with patients with grade B leakage. Mortality in patients with grade C leakage was higher compared with grade B leakage, although nonsignificant (5.8% vs 2.5%; p = 0.12). Multivariate analysis showed that patients with diverting stomas (n = 2866) had a decreased risk of developing grade C leakage compared with grade B (OR = 0.17 (95% CI, 0.10-0.29)). Male patients had an increased risk of developing grade C anastomotic leakage, and patients receiving neoadjuvant treatment before surgery had an increased risk of developing grade B anastomotic leakage. LIMITATIONS Some possibly relevant variables, such as smoking and nutritional status, were not recorded in the database. CONCLUSIONS Anastomotic leakage after low anterior resection for rectal cancer was a frequent observed complication in this cohort. Differences in clinical outcome suggest that grade B and C leakage should be considered separate entities in future registrations. In patients with a diverting stoma, the chances of experiencing grade C anastomotic leakage were reduced. See Video Abstract at http://links.lww.com/DCR/A315.

Abstract
Anastomotic leak in the gastrointestinal tract is one of the most important complications of resection. They are the main cause of reoperation, their occurrence worsens the prognosis of the patient, increasing the proportion of direct mortality, as well as being a significant risk factor for recurrence of cancer. The risk of leaks within the gastrointestinal tract is greatly varied, depending on the location and extent of the resection, but also on patient, disease or a surgical procedure, including surgeon. To determine the potential risk of leakage can be significant for introduction some prophylactic actions. Some of them have the character of general recommendations, as proper nutrition of the patient in the perioperative period, while another part is directly connected to the surgical procedure. The second group includes protective stoma, the use of tissue glues, insertion transrectal drain for rectal anastomosis decompression, the use of stents or the use of collagen matrix coated with fibrinogen and thrombin. Important to reduce the proportion of leaks can be more precise and targeted prophylactic recommendations, based on the individualized determination of risk factors leaks. Further research for this purpose are necessary for this purpose, the big hope can be associated with data obtained through mobile applications.

Early closure of defunctioning stoma increases complications related to stoma closure after concurrent chemoradiotherapy and low anterior resection in patients with rectal cancer. World J Surg Oncol 2017; 15:80. [PMID: 28399874 PMCID: PMC5387334 DOI: 10.1186/s12957-017-1149-9] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2017] [Accepted: 04/05/2017] [Indexed: 12/14/2022] Open
Abstract
Background After a low anterior resection, creating a defunctioning stoma is vital for securing the anastomosis in low-lying rectal cancer patients receiving concurrent chemoradiotherapy. Although it decreases the complication and reoperation rates associated with anastomotic leakage, the complications that arise before and after stoma closure should be carefully evaluated and managed. Methods This study enrolled 95 rectal cancer patients who received neoadjuvant concurrent chemoradiotherapy and low anterior resection with anastomosis of the bowel between July 2010 and November 2012. A defunctioning stoma was created in 63 patients during low anterior resection and in another three patients after anastomotic leakage. Results The total complication rate from stoma creation to closure was 36.4%. Ileostomy led to greater renal insufficiency than colostomy did and significantly increased the readmission rate (all p < 0.05). The complication rate related to stoma closure was 36.0%. Patients with ileostomy had an increased risk of developing complications (p = 0.017), and early closure of the defunctioning stoma yielded a higher incidence of morbidity (p = 0.006). Multivariate analysis revealed that a time to closure of ≤109 days was an independent risk factor for developing complications (p = 0.007). Conclusions The optimal timing of stoma reversal is at least 109 days after stoma construction in rectal cancer patients receiving concurrent chemoradiotherapy and low anterior resection.

Abstract
Colorectal anastomotic leakage (CAL) remains a major complication after colorectal surgery. Despite all efforts during the last decades, the incidence of CAL has not decreased. In this review, we summarize the available strategies regarding prevention, prediction and intervention of CAL and categorize them into three categories: communication, infection and healing disturbances. These three major factors actively interact during the onset of CAL. We aim to provide an integrated approach to CAL based on its etiology. The intraoperative air leak test, intraoperative endoscopy, radiological examinations and stoma construction mainly aim to detect and to prevent communication between the intra- and extra-luminal content. Other strategies including postoperative drainage, antibiotics, and infectious-parameter evaluation are intended to detect and prevent anastomotic or peritoneal infection. Most currently available interventions for CAL focus on the control of communication and infection, while strategies targeting the healing disturbances such as lifestyle changes, oxygen therapy and evaluation of metabolic biomarkers still lack wide clinical application. This simplified categorization may contribute to an integrated understanding of CAL. We strongly believe that this integrated approach should be taken into consideration during clinical practice. An integrated approach to CAL could contribute to a better understanding of the etiology of CAL and eventually better patient outcome.

Abstract
Background Anastomotic leakage is a serious complication that can occur after anterior resection of the rectum. There is a question regarding whether the placement of a transanal tube can decrease the rate of anastomotic leakage. The aim of this systematic review and meta-analysis was to evaluate the efficacy of transanal tube placement after anterior resection. Methods We searched three major databases (PubMed, Embase, and the Cochrane Library) up until January 2015 for studies evaluating the benefit of transanal tubes after anterior resection for rectal cancer. The primary outcome measure was the rate of clinical anastomotic leakage. Secondary outcome was the rate of reoperation. Pooled risk ratios (RR) with 95 % confidence intervals (CI) were obtained using random effects models. Results One randomized controlled trial and three observational studies involving 909 patients met inclusion criteria. Clinical anastomotic leakage occurred in 3.49 % (14 of 401) of patients with transanal tubes and 12.01 % (61 of 508) of patients without transanal tubes. Meta-analysis of the studies showed a lower risk of anastomotic leakage (RR, 0.32; 95 % CI 0.18–0.58) and reoperation related to leakage (RR, 0.19; 95 % CI 0.08–0.46) when the transanal tube was placed. Conclusions While studies are few and mostly observational, the data to date indicate that placement of a transanal tube decreases the rate of clinical anastomotic leakage and reoperation related to leakage. More studies are needed to confirm these findings.

Postoperative Hemodynamic Index Measurement With Miniaturized Dynamic Light Scattering Predicts Colorectal Anastomotic Healing. Surg Innov 2015; 23:115-23.

Abstract
INTRODUCTION Perioperative bowel perfusion (local hemodynamic index [LHI]) was measured with a miniaturized dynamic light scattering (mDLS) device, aiming to determine whether anastomotic perfusion correlates with the anastomotic healing process and whether LHI measurement assists in the detection of anastomotic leakage (AL) in colorectal surgery. METHODS A partial colectomy was performed in 21 male Wistar rats. Colonic and anastomotic LHIs were recorded during operation. On postoperative day (POD) 3, the rats were examined for AL manifestations. Anastomotic LHI was recorded before determining the anastomotic bursting pressure (ABP). The postoperative LHI measurements were repeated in 15 other rats with experimental colitis. Clinical manifestations and anastomotic LHI were also determined on POD3. Diagnostic value of LHI measurement was analyzed with the combined data from both experiments. RESULTS Intraoperative LHI measurement showed no correlation with the ABP on POD3. Postoperative anastomotic LHI on POD3 was significantly correlated with ABP in the normal rats (R(2) = 0.52; P < .001) and in the rats with colitis (R(2) = 0.63; P = .0012). Anastomotic LHI on POD3 had high accuracy for identifying ABP <50 mm Hg (Area under the curve = 0.86; standard error = 0.065; P < .001). A cutoff point of 1236 yielded a sensitivity of 100% and a specificity of 65%. On POD3, rats with LHIs <1236 had significantly higher dehiscence rates (40% vs 0%), more weight loss, higher abscess severity, and lower ABPs (P < .05); worse anastomotic inflammation and collagen deposition were also found in the histological examination. CONCLUSION Our data suggest that postoperative evaluation of anastomotic microcirculation with the mDLS device assists in the detection of AL in colorectal surgery.

Abstract
BACKGROUND There have been few studies describing the use of indocyanine green (ICG) fluorescent imaging during robot-assisted (RA) sphincter-saving operations (SSOs) and assessing its potential role in reducing anastomotic leak (AL). METHODS A consecutive cohort of 436 rectal cancer patients who underwent curative RA SSOs were prospectively enrolled during 2010-2014, including 123 patients with ICG imaging (ICG+ group) and 313 patients without ICG imaging (ICG- group). RESULTS ICG imaging appeared to be helpful in identifying competent perfusion of the bowel adjacent to the anastomosis in 13 patients (10.6%) who might be susceptible to bowel ischaemia, including restrictive mesocolon. AL was remarkably greater in the ICG- group compared with the ICG+ group (5.4% vs 0.8%; p = 0.031). CONCLUSIONS ICG imaging during RA SSO provides accurate real-time knowledge of the perfusion status at or near the anastomosis, specifically reducing AL in patients who may incur bowel ischaemia.

Abstract
AIM A study was carried out to determine the relationship between mesorectal lymph nodal involvement and T stage in a group of patients with a rectal cancer involving less than one-quarter of the rectal circumference, such as might be selected for local excision. METHOD The data of patients having rectal resection between 2010 and 2014 were prospectively entered in a rectal carcinoma registry. A model for describing tumours involving less than one quadrant of the rectal circumference was created to facilitate the evaluation process. RESULTS In all, 304 patients were included in the study. In 68 (22.4%) a small tumour (< 1 quadrant involved) was found. Of these, 26.5% had positive mesorectal lymph nodes (N+). In lesions of Stage ypT0 cancer 12.5% patients were node positive, in Stage Tis and T1 tumours there was no case of node positivity, but in Stage T2 and Stage T3 cancers the incidence of node positivity was 27.5% and 64%. CONCLUSION The study demonstrated that, even for small tumours involving only one rectal quadrant, the risk of lymph nodal involvement was about 25%. Had the patients undergone local excision the treatment would have been incomplete.
