Abstract
Background The aim of this study was to investigate whether the robotic platform can have a positive impact on the rate of sphincter preservation in patients with rectal tumors, undergoing robotic total mesorectal excision (TME), in comparison with laparoscopic or open TME. We also analyzed and compared short-term outcomes. Methods A prospectively collected robotic database was reviewed and compared with the trust and national data. Three groups were designed according to the surgical technique: open, laparoscopic and robotic. This includes all resections for mid and low rectal cancer which were performed with the robotic platform, over a period of 4 years, versus the trust data for the same period. Results Two hundred ninety-seven patients with mid and low rectal cancers were analyzed. Demographics for the groups (gender, age, and body mass index) were similar but distance from anal verge was shorter in the robotic group (7 vs. 8.5 cm, P < 0.001). The percentage of abdominoperineal resection (APR) rate was significantly lower in the robotic group (13.5% vs. 39.6% vs. 52.4% for the open group, P < 0.001). Median length of stay, complication rate, and positive circumferential resection margin (CRM) rate for the robotic group were also statistically significantly lower than those for both laparoscopic and open groups. Conclusion Robotic surgery for mid and low rectal cancer is safe and feasible, and could help surgeons perform ultra-low anterior resections, rather than APRs and save patients' sphincters. Positive CRM is low, which could lead to improved oncological outcomes.

Abstract
Intersphincteric resection (ISR), as an ultra-low sphincter-preserving operation, is widely used in clinical practice at present. ISR can allow some patients with very low rectal cancer to avoid the pain of anal resection while ensuring oncological efficacy. However, the procedure of ISR requires wider intersphincteric dissection which may cause nerve damage, and the removal of partial or total internal anal sphincter as an "inherent defect" of ISR can result in poor anal function postoperatively. Based on the in-depth understanding of regional anatomy and physiological function, the author proposed a new functional sphincter preservation operation for very low rectal cancer-conformal sphincter preservation operation (CSPO) which has achieved good outcome in clinical practice. This article will revisit the brief history of rectal cancer surgery and discuss the main mechanisms underlining the poor anal function after ISR. Based on the anatomical study of the pelvic floor and anal canal, CSPO can improve the postoperative anal function of very low rectal cancer patients by reducing the damage of the autonomic nerves, receptor corpuscles and muscle fibers in the intersphincteric space, retaining more dentate line and internal sphincter with the design of resection line of tumor lower border under direct vision, and elevating the anastomosis height. At the same time, the future treatment prospect of low rectal cancer is envisioned.

Abstract
BACKGROUND A better understanding of the impact of body-mass index (BMI) on the course of multimodal therapy and oncologic outcome in locally advanced rectal cancer could provide new insights for optimization of treatment and supportive strategies. PATIENTS AND METHODS Correlations of BMI with pretreatment clinical, surgical, and pathological characteristics, toxicity and treatment adherence using the Pearson's Chi-squared test or logistic regression were analyzed in the CAO/ARO/AIO-04 III trial cohort (n = 1236). One-way ANOVA or Welch test were used to analyze correlations of baseline blood-parameters and BMI. The prognostic role of BMI was examined with log-rank test and multivariate cox regression. RESULTS Obese had a better ECOG performance status (P = 0.027) but were less likely to undergo sphincter preserving surgery (P = 0.01). Post-surgical complications did not differ significantly between BMI classes, whereas underweight was associated with increased neutrophil (P = 0.025) and platelet counts (P < 0.001), poorer TME quality (P = 0.007) and increased incidence of acute organ toxicity (P < 0.001). After a median follow-up of 50 months, underweight [HR 1.896, P = 0.014] and overweight [HR 1.392, P = 0.042] were associated with worse DFS. Obese patients had an increased risk of death [HR 1.653, P = 0.032]. Normalweight men showed superior OS compared to underweight [HR 4.070, P = 0.002], overweight [HR 2.077, P = 0.010], severe overweight [HR 1.886, P = 0.026] and obese [HR 2.046, P = 0.015] men. Adding oxaliplatin to standard CRT significantly improved DFS in obese patients (P = 0.034). CONCLUSION In our study, underweight and overweight correlated with inferior DFS, underweight experienced more organ toxicity and obesity was associated with an increased risk of abdominoperineal resection and poorer overall survival.

Abstract
BACKGROUND Fistula-in-ano due to cryptoglandular disease is a common condition. While a simple anal fistula can be treated successfully by a fistulotomy, the risk of potential damage to the anal sphincters and subsequent poor functional outcomes persist in a large portion of patients with complex fistulae. Several sphincter-preserving treatment procedures have been described for complex fistulae over the past 3 decades, with variable results and complication rates, and no procedure is proven to be superior to the others. We developed external sphincter-sparing anal fistulotomy (ESSAF), a reproducible simple modification of the ligation of intersphincteric fistula tract (LIFT) technique for the treatment of complex fistula-in-ano.. The aim of the present study was to describe the technique and our outcomes. METHODS This was a retrospective review of all patients who underwent ESSAF for a complex anal fistula at our institution from January 2014 to December 2019. The primary outcome measure of this study was the primary fistula healing rate. Secondary outcome measures included fecal and/or gas incontinence and postoperative complications. During the ESSAF procedure, the mucosa and skin overlying the fistula tract are incised to allow complete exposure of the sphincter complex. Then the internal sphincter muscle fibers overlying the tract are divided and the tract is meticulously curetted and debrided. Next, the internal opening of the tract traversing the external sphincter muscle is suture-ligated with absorbable sutures. Then, a minimal amount of mucosa is advanced and the incision is partially closed with absorbable sutures, while its external portion is left open for drainage. RESULTS Fifty-nine patients [43 males, median age was 50 years (range 36-63 years)] underwent ESSAF for complex anal fistula during the study period. Mean follow-up was 12 ± 14.7 months. Of the 59 patients, 42 (71.2%) experienced fistula closure, with a median healing time of 8 weeks (IQR 4-16 weeks). None of the patients developed significant anal incontinence following the procedure. One patient (1.7%) suffered from soiling and another patient (1.7%) developed postoperative bleeding. There were no infectious complications. Of the 17 patients (28.8%) who failed to heal successfully, 9 (15.2%) did not heal primarily and 8 (16%) experienced recurrence after complete healing. Thirteen (76%) of these patients underwent reoperation with complete recovery after ESSAF (n = 4), fistulotomy (n = 8) or endorectal advancement flap (ERAF) (n = 1). Overall ESSAF initiated recovery in 93.2% of the patients. CONCLUSIONS ESSAF is a feasible, safe, reproducible and effective sphincter-sparing procedure for the treatment of complex anal fistulae.

Abstract
There has been an increase in the utilization of robotic surgery in addition to traditional open or laparoscopic approaches. Aim of this study is to compare the short-term outcomes for open, laparoscopic, and robotic surgery for rectal and sigmoid cancer. One hundred and forty-seven patients (open n = 48, laparoscopic n = 49, robotic n = 50) undergoing curative resections by two surgeons between 2013 and 2020 were included. Data analyzed included patient demographics, tumor characteristics, length of stay, post-operative outcomes, and pathologic surrogates of oncologic results, including total mesorectal excision (TME) quality, circumferential resection margin (CRM) involvement and lymph node (LN) yield. Median age of population was 68 years (IQR 59-73), majority (68%) were males. Median distance from anal verge in the robotic surgery group was 8 cm, compared to 15 and 14.5 cm in the open and laparoscopic groups, respectively, p = 0.029, (laparoscopic vs robotic, p = 0.005 and open vs robotic, p = 0.027). Proportion of patients who received neoadjuvant radiotherapy in robotic surgery group was higher, p = 0.04. In sub-group of tumors between 3 and 7 cm from anal verge more patients in the robotic surgery group had sphincter preservation, p = 0.006. Length of stay, maximum C-reactive protein, and white blood cell rise favored minimally invasive approaches compared to open surgery. There were no differences in post-operative complications, lymph node yield or CRM positivity rate between the three groups. Robotic surgery approach is safe and allows sphincter preservation without compromising TME quality in rectal cancer surgery.

Abstract
BACKGROUND In patients with ultralow rectal cancer, surgical resection of the tumor without impairing sphincter function remains a technical challenge. The purpose of this study was to describe a new technique of transanal natural orifice specimen extraction (NOSE) surgery using our independently developed devices, aiming to achieve precise cancer resection and preserve sphincter function in patients with ultralow rectal cancer. METHODS Precision functional sphincter-preserving surgery (PPS) was performed on nineteen patients with ultralow rectal cancer between June 2019 and April 2020. With the help of our independently developed devices, surgeons directly and accurately removed the lower edge of the tumor and retained healthy rectal tissue on the nontumorous side. Hand-sewn anastomosis with a mattress suture was used to achieve sturdy anastomosis. Preoperative baseline characteristics, operative details, 90-day postoperative complications, costs, and anal function score at 6 months after surgery were documented. RESULTS Nineteen ultralow rectal cancer patients with a median distance to the dentate line of 2.0 cm successfully underwent PPS without serious postoperative complications. Six out of nineteen patients (31.6%) received a prophylactic stoma. The average cost was 62164.1 yuan. At 6 months after surgery, the average Wexner anal function score and the average Vaizey score were both 3 points. CONCLUSIONS PPS can be employed to precisely resect rectal tumors and preserve sphincter function in ultralow rectal cancer patients. The use of our devices enhanced surgical efficiency, reduced the need for prophylactic stoma, reduced surgery-related costs, and prevented abdominal surgical incisions.

Abstract
BACKGROUND Epidemiologically, in China, locally advanced rectal cancer is a more common form of rectal cancer. Preoperative neoadjuvant concurrent chemoradiotherapy can effectively reduce the size of locally invasive tumors and improve disease-free survival (DFS) and pathologic response after surgery. At present, this modality has become the standard protocol for the treatment of locally advanced rectal cancer in many centers, but the optimal time for surgery after neoadjuvant therapy is still controversial.
AIM To investigate the impact of time interval between neoadjuvant therapy and surgery on DFS and pathologic response in patients with locally advanced rectal cancer.
METHODS A total of 231 patients who were classified as having clinical stage II or III advanced rectal cancer and underwent neoadjuvant chemoradiation followed by surgery at the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from November 2014 to August 2017 were involved in this retrospective cohort study. The patients were divided into two groups based on the different time intervals between neoadjuvant therapy and surgery: 139 (60.2%) patients were in group A (≤ 9 wk), and 92 (39.2%) patients were in group B (> 9 wk). DFS and pathologic response were analyzed as the primary endpoints. The secondary endpoints were postoperative complications and sphincter preservation.
RESULTS For the 231 patients included, surgery was performed at ≤ 9 wk in 139 (60.2%) patients and at > 9 wk in 92 (39.8%). The patients’ clinical characteristics, surgical results, and tumor outcomes were analyzed through univariate analysis combined with multivariate regression analysis. The overall pathologic complete response (pCR) rate was 27.2% (n = 25) in the longer time interval group (> 9 wk) and 10.8% (n = 15) in the shorter time interval group (≤ 9 wk, P = 0.001). The postoperative complications did not differ between the groups (group A, 5% vs group B, 5.4%; P = 0.894). Surgical procedures for sphincter preservation were performed in 113 (48.9%) patients, which were not significantly different between the groups (group A, 52.5% vs group B, 43.5%; P = 0.179). The pCR rate was an independent factor affected by time interval (P = 0.009; odds ratio [OR] = 2.668; 95%CI: 1.276-5.578). Kaplan-Meier analysis and Cox regression analysis showed that the longer time interval (> 9 wk) was a significant independent prognostic factor for DFS (P = 0.032; OR = 2.295; 95%CI: 1.074-4.905), but the time interval was not an independent prognostic factor for overall survival (P > 0.05).
CONCLUSION A longer time interval to surgery after neoadjuvant therapy may improve the pCR rate and DFS but has little impact on postoperative complications and sphincter preservation.

Abstract
Total mesorectal excision (TME) is currently recognised as the standard of care for patients with rectal cancer. Complete TME is known to be associated with lower rates of recurrence. Robotic and endoscopic TaTME approaches are reported to offer excellent proximal and distal rectal dissection into the TME plane, however, combining both approaches in a hybrid procedure could potentially optimise visualisation of the dissection plane and confer improved circumferential and distal margin rates. The aim of this study was to analyse the feasibility of a hybrid robotic abdominal approach with conventional TaTME for rectal cancer. Furthermore, pathological and patient outcomes were assessed. A review of prospectively maintained databases was undertaken to assess all patients undergoing robotic TME surgery for rectal tumours from August 2016 to October 2017. Patient demographics, tumour characteristics and outcomes were collated from patient charts and hospital databases. All patients underwent a modified Cecil approach after multidisciplinary team discussion. Eight patients (7 male, 1 female) underwent a combined hybrid approach with a median age of 60 years (range 47-73) and BMI of 29.5 (range 20-39.1) kg/m2. Median distance from the anorectal junction (ARJ) was 7.5 (range 4-13) cm. Six patients underwent neoadjuvant treatment with chemoradiotherapy. Patients had a median length of stay (LOS) of 9 (range 4-33) days. There were no intra-operative complications encountered and no patients required a conversion to an open procedure. Complications included one anastomotic leak and one presacral collection. All patients had a complete TME with RO resection with a median number of lymph nodes harvested was 22 (range 6-37) lymph nodes. This hybrid technique is a feasible, practical and operatively favourable approach to rectal cancer surgery with initial pathological outcomes and complication profile equivalent to other approaches.

Abstract
In 2012 we started a prospective observational study at San Giovanni Addolorata Hospital in Rome for patients with rectal cancer with complete response to neoadjuvant therapy (nCRT). In our, IRB approved protocol, patients are evaluated at time 0 by physical, endoscopic, pathological and radiological examinations. 6 weeks after completion of nCRT they are re-evaluated. In case of persistence or progression of disease patients undergo surgery with Total Mesorectal Excision. In case of complete or major clinical response they are re-evaluated at 12 weeks and subjected to transanal surgical excision to confirm complete pathological response (pCR). If tumor is found in the transanal excision specimen the patient is operated upon whereas patients with pCR are followed up at 3 months interval.

Abstract
Background Low rectal cancer surgery without anus conservation needs permanent ileostomy or colostomy which seriously affects the quality of life of patients. Therefore, low rectal cancer surgery not only pays attention to the safety of surgical treatment but also to the anus conservation. Methods Sixty-seven patients suffering from low rectal cancer had undergone laparoscopic surgery which was analyzed through retrospective study. They were divided into the anus-conserving and non-anus-conserving groups. Thirty-five set of pelvic data was obtained from the preoperative CT and MRI images. After that, the discriminant function was obtained to predict the surgery methods for patients with low rectal carcinoma. Results Anal-conserving group discriminant function (F1) = − 33.698 + 6.045 × anal margin distance (cm) + 1.105 × T4; non-anus-conserving group discriminant function (F2) = − 14.125 + 3.138 × anal margin distance (cm) + 0.804 × T4. If F1 is greater than F2, then the case can be treated as the anus reservation while if F2 is greater than F1 the case cannot be treated anus reservation. The accuracy of the discriminant function was evaluated which was found to be 97%. Conclusion The discriminant function of pelvic data provides anatomical basis for the choice of surgical methods for low rectal cancer.

Abstract
PURPOSE Sphincter-saving surgery is widely accepted operative modality to treat rectal cancer. It often requires temporary diverting stoma to avoid the complications of anastomotic failure. This study investigates the cumulative failure rate in sphincter preservation for rectal cancer and the risk factors associated with the permanent stoma. METHODS A retrospective study on 358 patients diagnosed with primary rectal cancer from 2009 to 2013 was conducted at a single institute. Three hundred and thirty-one out of 358 patients with rectal cancer located within 12 cm from the anal verge, who underwent sphincter-preserving surgery, were included in this study. The cumulative rate for permanent stoma was calculated. Univariate and multivariate analysis were performed, comparing the patients with stoma to the ones without. RESULTS Temporary diverting stoma was created in 223 (82%) patients. After median follow-up of 42 months, 18 patients (6.6%) persistently used temporary stoma or required re-creation of stoma. Univariate analysis revealed that BMI, tumor location below 4 cm from the anal verge, coloanal anastomosis, anastomotic leakage, and local recurrence were significantly associated with persistent use or re-formation of stoma. Multivariate analysis showed that anastomotic leakage (OR 50.3; 95% CI, 10.1-250.1; p < 0.0001) and local recurrence (OR 11.3; 95% CI, 1.61-78.5; p = 0.015) were the independent risk factors. CONCLUSION Patients with anastomotic leakage and local recurrence are at high risk for permanent stoma. Not only should patients be fully informed of possible failure in sphincter preservation preoperatively, but also patient-oriented decision should be made on patient-tailored surgical plan.

Abstract
Purpose Tumors at the level of the anorectal junction had required total levator-ani muscle excision to achieve an adequate resection margin. However, in the cases of tumor invading ipsilateral levator-ani muscle and intact external sphincter, en bloc resection of rectum with levator-ani muscle including tumor would be possible. This hemilevator excision (HLE) technique enables preserving the anal sphincter function while obtaining oncologic clearance and avoiding permanent colostomy in those patients. This study aimed to evaluate the surgical outcomes and feasibility of HLE. Methods Data on 13 consecutive patients who underwent HLE for pathologically proven low rectal cancer were retrospectively collected. All 13 patients presented low rectal cancer at the anorectal ring level that was suspected to invade or abut to the ipsilateral side of the levator-ani muscle. Results A secure resection margin was achieved in all cases, and anastomotic leakage occurred in 2 patients. During follow-up, 3 patients experienced tumor recurrence (2 systemic and 1 local). Among 6 patients who underwent diverting ileostomy closure after the index operation, 2 complained of fecal incontinence. The other 4 patients without fecal incontinence showed <10 times of bowel movement per day. Accessing their incontinence scale, mean Wexner score was 9.4. Conclusion HLE is a novel sphincter-preserving technique that can be a treatment option for low rectal cancer invading ipsilateral levator-ani muscle, which has been an indication for abdominoperineal resection (APR) or extralevator APR. However, the long-term oncologic and functional outcomes of this procedure still need to be assessed to confirm its validity.

Abstract
BACKGROUND The challenge of performing a good total mesorectal excision (TME) dissection, particularly in the distal 1/3 of the rectum, has spurred interest in new techniques. Robotic surgery is advocated by some, and more recently, a "new" approach, the transanal total mesorectal excision, has been popularized to address this problem. While great interest in this technique exists, little long-term outcome data are available. We have been utilizing a transanal abdominal transanal approach to TME in order to facilitate the distal dissection, and here, we provide our long-term outcomes using this approach in the management of rectal cancer. METHODS From a prospectively maintained rectal cancer database, we identified 373 consecutive rectal cancers treated with sphincter preservation surgery through a combined transanal and abdominal approach to TME. Perioperative, pathological, and oncologic outcomes were analyzed. RESULTS Three hundred and seventy-three patients with rectal cancer underwent a transanally initiated TME with mean follow-up of 5.5 years. 91% of cancers were in the distal rectum. 68.9% were men and 53.2% of cancers were tethered or fixed on presentation. 97.7% received neoadjuvant radiotherapy (mean 5405 cGy, 5-fluorouracil based); average time from completion of neoadjuvant therapy to surgery was 11 weeks. 180 and 193 patients underwent completion of their operation through open and laparoscopic abdominal approaches. 96% of TME specimens were complete/near complete, 94% had a negative circumferential resection margin, and 98.6% had a negative distal margin. Perioperative morbidity and mortality rates were 13.4 and 0.3%. Overall local recurrence (LR), DM, and Kaplan-Meier 5-year actuarial survival were 7.4, 19.5, and 90%, respectively. CONCLUSION This is the first report of long-term data using a transanal approach to TME supporting this approach for rectal cancer. Our data with 5-year follow-up show that adequate distal and circumferential margins with very good-quality TME specimens, and a low risk for LR with excellent overall survival can be achieved using this technique. Our long-term results support the promising reports of early experiences in the literature.

Abstract
PURPOSE This retrospective study investigates the safety of neoadjuvant chemotherapy with oxaliplatin capecitabine (CapeOx), followed by laparoscopic surgery, for lower rectal cancer, and its efficacy in preserving the sphincter. METHODS Ten patients with diagnosed lower rectal cancer received three or four cycles of neoadjuvant CapeOx chemotherapy, prior to undergoing low anterior resection or intersphincteric resection, with total mesorectal excision. The primary outcomes were R0 resection and the rate of sphincter preservation. RESULTS Nine patients completed CapeOx as scheduled and a partial response was achieved in four; thus, the overall response rate was 40% (n = 4/10). After surgical intervention, 80% of tumors displayed downstaging. Postoperative anastomosis leakage developed in one patient. The distance from the anal verge to the tumor increased by 60% (median 1.5 cm) after CapeOx treatment. The anal sphincter was preserved in all patients and all pathological distal and radial margins were negative (R0 resections). A pathological complete response was achieved in one patient. CONCLUSIONS Neoadjuvant CapeOx chemotherapy is a promising approach, because it extended the distance from the anus to the tumor. Subsequent laparoscopic intervention for advanced lower rectal cancer could allow for safe preservation of the sphincter.

Abstract
BACKGROUND Transanal minimally invasive surgery (TAMIS) represents a promising technique for total mesorectal excision (TME) with respect to radicalness and preservation of function. There are only few publications in the literature describing results in patients with distal rectal cancer. METHODS Between May 2013 and March 2015, 24 selected patients with a rectal carcinoma < 6 cm from the anal verge underwent a laparoscopically assisted TAMIS TME (Hybrid-TAMIS TME) procedure. This prospective observational study was conducted to examine the safety of the technique and the quality of TME surgery in distal rectal cancer and to assess the short-term postoperative outcome. RESULTS The median age of patients (18 male and 6 female) at the time of surgery was 57 years (range 35-77 years) and 7 patients (29 %) had a body mass index (BMI) > 30 kg/m(2). Specimen excision was carried out transanally in 19 patients. Pathological grading of TME specimens was good in 22 (92 %) and moderate in 2 cases. After neoadjuvant radiochemotherapy a complete pathological remission was identified in five patients. The median distal resection margin was 7 mm (range 2-30 mm), the median circumferential resection margin was 6 mm (range <1 mm-30 mm) and in 2 patients the tumor was ≤ 1 mm from the positive circumferential margin. A colonic reservoir was created in 19 patients (79 %) and no 30-day mortalities occurred. Morbidity was 29 %, including 1 anastomotic leak, 2 hematomas and 1 neurogenic bladder. CONCLUSION Hybrid-TAMIS TME for distal rectal cancer is safe and can provide a sphincter-preserving high-quality TME in difficult cases. Studies with long-term follow-up assessing oncological and functional results are mandatory.

Abstract
INTRODUCTION There is scarce data relating to methods to improve sphincter preservation in rectal gastrointestinal stromal tumor (GIST). Increasing the duration of neoadjuvant (NA) imatinib resulting in improved sphincter preservation rate has not been established. This retrospective analysis looks at the rates of sphincter preservation in rectal GIST with NA imatinib and effect of duration of NA imatinib on the same to find out optimum duration of NA with respect to sphincter preservation in rectal GIST patients. METHODS Twenty-three cases of GIST of lower third of rectum were treated at our centre from 2005 till 2015. NA imatinib was used in a dose of 400 mg. Response evaluation was done every 3 months with a pelvic magnetic resonance imaging. Surgical management was determined by a team of experienced gastrointestinal oncosurgeons. RESULTS Five patients underwent upfront surgery which included local resection in four patients and abdominoperineal resection in one patient. NA imatinib was used in 69.5 % (16/23) patients. Median duration of NA imatinib was 15 months (3-84 months). Amongst who underwent a sphincter-salvage surgery median duration of NA imatinib was 13 months whereas 18 months in patients who required a sphincter-sacrificing surgery (p = 0.683). The radiologic response included partial response in 75 % (12/16) patients, stable disease in 18.7 % (3/16) and one with progressive disease. Definitive surgical resection was possible in 13 patients (81.3 %) after NA imatinib. Median progression-free survival (PFS) was 120 months in the whole cohort whereas median overall survival (OS) was not reached. Four-year estimated PFS and OS was 81 % and 100 %, respectively. Median disease-free survival in upfront surgery group vs. neoadjuvant imatinib group was 70 vs. 120 months, respectively (p = 0.039). CONCLUSION Neoadjuvant imatinib appears to be a useful option in improving chances of sphincter preservation without adversely affecting the outcome. Use of neoadjuvant imatinib leads to improvement in progression-free survival in patients with GIST of lower third of the rectum.

Abstract
BACKGROUND In a prospective multicenter observational study (OCUM) neoadjuvant chemoradiotherapy (nRCT) was selectively administered depending on the risk of local recurrence and based on the distance between tumor and mesorectal fascia in pretherapeutic high-resolution magnetic resonance imaging (MRI). OBJECTIVE Frequency and quality of abdominoperineal excision (APE) and sphincter preserving operations. PATIENTS AND METHODS Of 642 patients treated in 13 hospitals 389 received surgery alone and 253 nRCT followed by surgery. By univariate and multivariate analysis risk factors for APE were determined. Quality parameters were the quality grade of mesorectal excision, the pathohistological involvement of the circumferential resection margin and intraoperative local dissemination of tumor cells. RESULTS AND DISCUSSION In 12.8 % of the patients APE was performed. Independent risk factors for APE were tumor location in the lower third of the rectum and the individual hospitals, where APE varied between 0 and 32 %. This variation was chiefly caused by the different case mix. Hospitals with a high APE rate (> 30 %) treated significantly more patients with very low lying carcinomas (< 3 cm above the anal verge) and more advanced tumors. The median height of the tumor in cases of APE was nearly equal in all participating hospitals. Independent on the number of cases the quality of rectal surgery was high. Within the patient groups of primary surgery and nRCT the oncological quality parameter did not significantly differ between sphincter preservation and APE. As far as sphincter preservation is concerned the results justify a selective application of nRCT in patients with rectal carcinoma. The long-term results still have to be awaited.

Abstract
BACKGROUND The occurrence of anastomotic leakage (AL) after sphincter preserving anterior rectal resection in patients with rectal cancer is associated with increased morbidity and mortality. The impact of AL on long-term survival has, however, still not been sufficiently investigated and is currently the subject of controversial discussion. OBJECTIVES The aim of this study was to investigate the impact of AL on long-term survival in patients with Union of International Cancer Control (UICC) (y)0-III stage mid-to-low rectal cancer who underwent sphincter preserving rectal resection. MATERIAL AND METHODS A total of 108 patients with a mid-to-low rectal cancer (UICC stage (y)0-III) who underwent sphincter preserving surgery between January 2003 and October 2010 were identified within the institutional prospective colorectal cancer database. The impact of AL on 5-year overall (OS), cancer specific (CSS) and relapse-free survival (RFS) was investigated. RESULTS The overall leakage rate was 17.6 % (grade A 4.6 %, grade B 4.6 % and grade C 8.3 %). After a median follow-up of 70 months (range 24-123 months), patients with an anastomotic leakage had a significantly decreased 5-year OS (63.6 % versus 87.8 %, p = 0.02), CSS (72.2 % versus 93.5 %, p = 0.02) and RFS rate (61.1 % versus 84.2 %, p = 0.01). In univariable Cox regression analysis AL was associated with an unfavorable OS (hazard ratio HR 3.05, 95 % CI: 1.11-8.39, p = 0.03), CSS (HR 4.21, 95 % CI: 1.13-15.70, p = 0.03) and RFS (HR 3.02, 95 % CI: 1.20-7.58, p = 0.02). CONCLUSION In the study cohort anastomotic leakage after sphincter preserving anterior resection in patients with mid-to-low rectal cancer was associated with a significantly unfavorable impact on overall and oncological survival.

Abstract
Background Preoperative chemoradiation (CRT) is considered the standard of care in the management of stage II/III rectal cancer. The aim of this retrospective study was to assess the efficacy and safety of preoperative CRT in our patient cohort with locally advanced rectal adenocarcinoma. Methods Forty patients with cT3-4N0-2M0 adenocarcinoma of the lower (n = 26) and mid/upper (n = 14) rectum were enrolled in this study between 2001 and 2012. Radiotherapy (RT) was given to the pelvis. The median prescribed dose was 45 Gy (daily dose, 1.8 - 2.0 Gy). All patients received chemotherapy concurrently with RT and underwent surgery 6 - 8 weeks after CRT. Low anterior resection (LAR) was achieved in 21 patients. Total mesorectal excision (TME) was performed in 24 patients. Results Tumor downstaging (expressed as TN downstaging) was observed in 15 patients (38%); a pathological complete response (pCR) was pathologically confirmed in six of them. In nine out of the 26 (23%) patients with low lying tumors, sphincter preservation (SP) was possible. SP was also possible in all but one patient (13%) who achieved a pCR. In three out of 15 patients (8%) with preoperative sphincter infiltration, SP was achieved. With a median follow-up of 58 months, the 4-year local control (LC), distant metastases-free survival (DMFS), disease-free survival (DFS) and overall survival (OS) rates were 89.7%, 86.9%, 79.5% and 81.2%, respectively. The pretreatment tumor size was predictive of response to preoperative CRT. The response to preoperative CRT did show a significant impact on DFS and on OS. TME resulted in a statistically significant increased DFS rate. No grade 3/4 acute toxicity was reported. Three patients developed grade 3 late side effects. Conclusion Preoperative CRT demonstrates encouraging rates of disease control and facilitates complete resection and SP in advanced rectal cancer with acceptable late toxicity.

Abstract
Rectal cancer surgery has dramatically changed with the introduction of the total mesorectal excision (TME), which has demonstrated to significantly reduce the risk of local recurrence. The combination of TME with radiochemotherapy has led to a reduction of local failure to less than 5%. On the other hand, surgery for rectal cancer is also impaired by the potential for a significant loss in quality of life. This is a new challenge surgeons should think about nowadays: If patients live more, they also want to live better. The fight against cancer cannot only be based on survival, recurrence rate and other oncological endpoints. Patients are also asking for a decent quality of life. Rectal cancer is probably a paradigmatic example: Its treatment is often associated with the loss or severe impairment of faecal function, alteration of body anatomy, urogenital problems and, sometimes, intractable pain. The evolution of laparoscopic colorectal surgery in the last decades is an important example, which emphasizes the importance that themes like scar, recovery, pain and quality of life might play for patients. The attention to quality of life from both patients and surgeons led to several surgical innovations in the treatment of rectal cancer: Sphincter saving procedures, reservoir techniques (pouch and coloplasty) to mitigate postoperative faecal disorders, nerve-sparing techniques to reduce the risk for sexual dysfunction. Even more conservative procedures have been proposed alternatively to the abdominal-perineal resection, like the local excisions or transanal endoscopic microsurgery, till the possibility of a wait and see approach in selected cases after radiation therapy.

Abstract
AIMS Dissection of the lower rectum in some low rectal and pararectal pathologies can be technically difficult that it ends up in abandoning the procedure or raising a permanent stoma. The recently described combined abdomino-perineal approach allows completion of rectal dissection from the perineal route and preservation of the anal sphincters. Patients requiring the combined approach are not seen frequently and reports on this new technique are scarce. The purpose of this study is to analyze our results of using the combined abdomino-perineal approach in different benign and malignant low rectal pathologies, and to describe two new indications for the technique. PATIENTS AND METHODS This is a retrospective analysis of prospectively collected data of 10 patients (8 males, age range 22-75 years), including 7 cancer patients who required the combined abdomino-perineal approach for completion of their procedures. Previously unreported indications for the technique included iatrogenic rectovaginal fistula and presacral tumor. The study was conducted in a tertiary referral colorectal unit in a university hospital. RESULTS The procedure was completed and the sphincters preserved in all patients. All cancer patients had adequate resection with good quality mesorectum. Continence was preserved in 4 patients. Three patients are living with permanent stoma. Anastomotic perineal fistula requiring dismantling the anastomosis and raising a permanent stoma occurred in one patient. CONCLUSIONS The combined abdomino-perineal approach is useful to complete rectal resection in a highly selected group of patients with technically difficult low rectal pathologies. The technique is probably safe in cancer patients and new indications are evolving. Expectations for preservation of continence are disappointing.

Abstract
Management of rectal cancer has markedly evolved over the last two decades. New technologies of staging have allowed a more precise definition of tumor extension. Refinements in surgical concepts and techniques have resulted in higher rates of sphincter preservation and better functional outcome for patients with this malignancy. Although, preoperative chemoradiotherapy followed by total mesorectal excision has become the standard of care for locally advanced tumors, many controversial matters in management of rectal cancer still need to be defined. These include the feasibility of a non-surgical approach after a favorable response to neoadjuvant therapy, the ideal margins of surgical resection for sphincter preservation and the adequacy of minimally invasive techniques of tumor resection. In this article, after an extensive search in PubMed and Embase databases, we critically review the current strategies and the most debatable matters in treatment of rectal cancer.

Abstract
AIM: To examine the influence of anastomosis level on defection and quality of life in low rectal cancer using a questionnaire and anus-rectal manometry.
METHODS: We selected 160 patients who were divided into 3 groups according to the distance between anastomosis and dentate line (A: 0-1.0 cm, B: 1.0-2.0 cm, C: 2.0-3.0 cm), who received evaluation with Wexner scoring systems at 3 months and at 1 year after operation, using FIQL questionnaire for quality of life and anus-rectal vectorial manometry 1 year after operation. The normal controls were 30 healthy people without anus-rectal disease and disordered defecation.
RESULTS: Lower anastomosis level meant higher Wexner scores (10.1 vs 6.1 vs 4.1, P < 0.05) at 3 mo after operation. After 1 year of adaptation and functional exercise, the scores of three groups decreased obviously (10.1 vs 5.7, 6.1 vs 3.1, 6.1 vs2.9, all P < 0.05). However, compared with B group and C group, A group still had significantly higher scores (5.7 vs 3.1, 2.9,P < 0.05), but no differences were detected between B group and C group. As for quality of life satisfaction, three groups of patients showed no significant differences in life-style, psychological coping/behavior, depression/self-feelings and embarrassing 1 year after operation.
CONCLUSION: For the low anterior resection of rectal cancer surgery, the lower of the position of anastomosis, the worse of the function and the quality of life. For the distance between stoma and dentate line less than 1 cm, the long-term survival quality of life has also declined markedly.
