Abstract
BACKGROUND Over 90% of rectal cancer patients develop low anterior resection syndrome (LARS) after sphincter-preserving resection. The current globally recognized evaluation method has many drawbacks and its subjectivity is too strong, which hinders the research and treatment of LARS. AIM To evaluate the anorectal function after colorectal cancer surgery by quantifying the index of magnetic resonance imaging (MRI) defecography, and pathogenesis of LARS. METHODS We evaluated 34 patients using the standard LARS score, and a new LARS evaluation index was established using the dynamic images of MRI defecography to verify the LARS score. RESULTS In the LARS score model, there were 10 (29.41%) mild and 24 (70.58%) severe cases of LARS. The comparison of defecation rate between the two groups was 29.36 ± 14.17% versus 46.83 ± 18.62% (P = 0.004); and MRI-rectal compliance (MRI-RC) score was 3.63 ± 1.96 versus 7.0 ± 3.21 (P = 0.001). Severe and mild LARS had significant differences using the two evaluation methods. There was a significant negative correlation between LARS and MRI-RC score (P < 0.001), and they had a negative correlation with defecation rate (P = 0.028). CONCLUSION MRI defecography and standard LARS score can both be used as an evaluation index to study the pathogenesis of LARS.

Abstract
INTRODUCTION Multiple reconstructive techniques have been described for reconstruction after a low anterior resection for carcinoma rectum. Colonic J pouch (CJP), Side to end anastomosis (SEA), transverse coloplasty pouch (TCP) and Straight Colo-rectal/anal anastomosis were the most widely studied. EVIDENCE ACQUISITION PubMed, Embase and Cochrane data base were searched for randomized, non-randomized studies and systematic reviews from inception of the databases till July 31st, 2023. EVIDENCE SYNTHESIS Considerable heterogeneity existed among different study findings. Reservoir techniques, including CJP, SEA, and TCP, exhibited reduced stool frequency, decreased urgency, and improved continence status compared to SCA, particularly in the short term. CJP maintained this advantage into the intermediate term. Other functional outcomes were similar among the techniques. However, these functional improvements did not translate into enhanced Quality of Life (QoL). TCP was associated with an elevated risk of anastomotic leaks. Other surgical outcomes remained comparable across all four techniques. Sexual outcomes also exhibited no significant variation. Some studies suggested that the size of the side limb in CJP or SEA may not significantly impact functional outcomes, implying that neorectum capacity may not be the primary determinant of improved function. The precise physiological mechanism underlying these findings remains unknown. CONCLUSIONS In the short and intermediate terms, reservoir techniques demonstrated superior functional outcomes, but long-term performance was comparable among all techniques. Notably, enhanced functional outcomes did not translate to improved Quality of Life. TCP, while effective, is linked to an increased risk of anastomotic complications, necessitating cautious utilization.

Abstract
PURPOSE This study aimed to compare the oncological and functional outcomes following intersphincteric resection (ISR) with transverse coloplasty pouch (TCP) or straight coloanal anastomosis (SCAA) for low rectal cancer. METHODS A single-center retrospective analysis was performed on patients with low rectal cancer who received ISR between January 2016 and June 2021. The primary endpoint was to compare the outcomes of bowel function within 1 year, 1 to 2 years, and 2 years after ileostomy closure in patients undergoing two different bowel reconstruction procedures (TCP or SCAA). The postoperative complications and oncological results were also compared between the two groups. RESULTS A total of 235 patients were enrolled in this study (SCAA group: 166; TCP group: 69). There was no significant difference in complications, including grades A-C anastomotic leakage (9.6% vs 15.9%), 3-year local recurrence rates (6.1% vs 3.9%), disease-free survival (82.4%vs 83.8%), or overall survival (94.1% vs 94.7%) between the two groups. Two years after ileostomy closure, 52.7% of patients in the SCAA group were assessed as having major low anterior resection syndrome (LARS), which was significantly higher than the 25.9% of patients in the TCP group (P = 0.014), but no difference was found prior to 2 years. Similar differences were seen in Wexner scores 2 years after surgery (P = 0.032). Additionally, TCP was an independent protective factor for postoperative bowel function as measured by both the LARS (OR, 0.28; 95% CI, 0.10-0.82; p = 0.020) and Wexner scoring (OR, 0.28; 95% CI, 0.09-0.84; p = 0.023). CONCLUSION This study suggests that TCP is a safe technique that may decrease bowel dysfunction after ISR for low rectal cancer compared with SCAA 2 years after ileostomy closure.

Abstract
BACKGROUND Several pivotal studies and international guidelines on the perioperative management of rectal cancer have been published. However, little is known about the current state of perioperative management of rectal cancer patients in clinical practice worldwide. METHODS An online survey including 13 questions focusing on key topics related to the perioperative management of patients with rectal cancer was conducted among colorectal surgeons registered within the database of the Research Institute Against Digestive Cancer (IRCAD). RESULTS A total of 535 respondents from 89 countries participated in the survey. Most surgeons worked in the European region (40.9%). Two hundred and fifty-four respondents (47.5%) performed less than 25% of surgical procedures laparoscopically. The most commonly used definition of the upper limit of the rectum was a fixed distance from the anal verge (23.4%). Magnetic resonance imaging was used to define the upper limit of the rectum by 258 respondents (48.2%). During total mesorectal excision (TME), 301 respondents (56.3%) used a high-tie technique. The most commonly constructed anastomosis was an end-to-end anastomosis (68.2%) with the majority of surgeons performing a leak test intraoperatively (88.9%). A total of 355 respondents (66.4%) constructed a diverting ostomy, and the majority of these surgeons constructed an enterostomy (82%). A total of 208 respondents (39.3%) closed a stoma within 8 weeks. Lastly, 135 respondents (25.2%) introduced a solid diet on postoperative day 1. CONCLUSION There is considerable heterogeneity in the perioperative management of rectal cancer patients worldwide with several discrepancies between current international practice and recommendations from international guidelines. To achieve worldwide standardization in rectal cancer care, further research is needed to elucidate the cause of this heterogeneity and find ways of improved implementation of best practice recommendations.

Abstract
Low anterior resection syndrome (LARS) describes the symptoms and experiences of bowel dysfunction experienced by patients after rectal cancer surgery. LARS is a complex and multifactorial syndrome exacerbated by factors such as low anastomotic height, defunctioning of the colon and neorectum, and radiotherapy. There has recently been growing awareness and understanding regarding the role of colonic motility as a contributing mechanism for LARS. It is well established that rectosigmoid motility serves an important role in coordinating rectal filling and maintaining continence. Resection of the rectosigmoid may therefore contribute to LARS through altered distal colonic and neorectal motility. This review evaluates the role of colonic motility within the broader pathophysiology of LARS and outlines future directions of research needed to enable targeted therapy for specific LARS phenotypes.

Abstract
BACKGROUND Following resection for low rectal cancer, numerous patients suffer from frequent bowel movements, fecal urgency, and incontinence. Although there is good evidence that colonic J-pouch reconstruction, side-to-end anastomosis, or a transverse coloplasty pouch (TCP) improves functional outcome, many surgeons still prefer straight coloanal anastomosis because it is technically easier and lacks the risk of pouch-associated complications. The present single-center study aimed to evaluate the practicability of TCPs in routine clinical practice as well as pouch-related complications. METHOD All consecutive patients who underwent low anterior rectal resection with restoration of bowel continuity for cancer during the period September 2008 to June 2018 were included. A TCP in combination with a diverting ileostomy was defined as the hospital standard. The feasibility and safety of TCPs were assessed in a retrospective single-center study. RESULTS A total of 397 patients were included in the study. A total of 328/397 patients underwent TCP construction (82.6%). Two pouch-related surgical complications occurred (0.6%); one case of pouch-related stenosis and one case of sutural insufficiency. Overall, leakage of the coloanal anastomosis was reported in 14.1% of patients with a TCP and in 18.8% of patients without a pouch (p=0.252). Diverting ileostomy was applied in 378/397 patients (95.2%). The 30-day mortality was 0.25%. CONCLUSION The present study is by far the largest single-center experience with TCP construction for low rectal cancer resection. The study shows that a TCP is technically applicable in the vast majority of cases (82.6%). Pouch-associated surgical complications are sporadic events. In our opinion, the TCP can be considered an alternative to J-pouch construction after low anterior rectal resection.

Abstract
Anastomosis is a crucial step in radical cancer surgery. Despite being a daily practice in gastrointestinal surgery, anastomotic leakage (AL) stands as a frequent postoperative complication. Because of increased morbidity, mortality, combined with longer hospital stay, the rate of re-intervention, and poor oncological outcomes, AL is considered the most feared and life-threatening complication after colorectal resections. Furthermore, poor functional outcomes with a higher rate of a permeant stoma in 56% of patients this could negatively affect the patient’s quality of life. This a narrative review which will cover intraoperative anastomotic integrity assessment and preventive measures in order to reduce AL. Although the most important prerequisites for the creation of anastomosis is well-perfused and tension-free anastomosis, surgeons have proposed several preventive measures, which were assumed to reduce the incidence of AL, including antibiotic prophylaxis, intraoperative air leak test, omental pedicle flap, defunctioning stoma, pelvic drain insertion, stapled anastomosis, and general surgical technique. However, lack of clear evidence of which preventive measures is superior over the other combined with the fact that the decision remains based on the surgeon’s choice. Despite the advances in surgical techniques, AL remains a serious health problem associated with increased morbidity, mortality with additional cost. Many preventative measures were employed with no clear evidence supporting the superiority of stapled anastomosis over hand-Sewn anastomosis, coating of the anastomosis, or pelvic drain. Defunctioning stoma, when justified it could decrease the leakage-related complications and the incidence of reoperation. MBP combined with oral antibiotics still recommended.

Abstract
BACKGROUND Options for reconstruction after low anterior resection (LAR) for rectal cancer include straight or side-to-end coloanal anastomosis (CAA), colonic J pouch and transverse coloplasty. This systematic review compared these techniques in terms of function, surgical outcomes and quality of life. METHODS A systematic literature search (MEDLINE, Embase and the Cochrane Library, from inception of the databases until November 2014) was conducted to identify randomized clinical trials comparing reconstructive techniques after LAR. Random-effects meta-analyses were carried out, and results presented as weighted odds ratios or mean differences with corresponding 95 per cent c.i. A network meta-analysis was conducted for the outcome anastomotic leakage. RESULTS The search yielded 965 results; 21 trials comprising data from 1636 patients were included. Colonic J pouch was associated with lower stool frequency and antidiarrhoeal medication use for up to 1 year after surgery compared with straight CAA. Transverse coloplasty and side-to-end CAA had similar functional outcomes to the colonic J pouch. No superiority was found for any of the techniques in terms of anastomotic leak rate. CONCLUSION Colonic J pouch and side-to-end CAA or transverse coloplasty lead to a better functional outcome than straight CAA for the first year after surgery.

Abstract
Standardizing total mesorectal excision (TME) has been a topic of interest since 1979 when Professor Richard J. Heald first described TME and a new approach to rectal cancer. The procedure is optimized only if every one of the relevant factors is tackled with precise attention to detail, so that the preoperative, operative, and postoperative practice is standardized completely. The same concept of TME standardization applies today regardless of technique chosen, that is, open laparoscopic, single-incision laparoscopic surgery, or robotic. This article reviews the relevant operative factors in performing a quality TME, looking at both the oncologic and nononcologic advantages and disadvantages. It supports TME as the standard of care in obtaining a negative circumferential margin for mid and lower-third rectal cancers, and discusses the role of tumor-specific mesorectal excision for upper-third rectal cancers. It discusses the new options and challenges each operative technique holds, and identifies the same standardized principles each must obey to provide the highest quality of oncologic resection. The operative documentation of these critical features from diagnostic workup to pathological reporting is also emphasized.

Abstract
Nearly half of patients undergoing low anterior rectal cancer resection have a functional sequelae after straight coloanal or low colorectal anastomoses (SA), including low anterior rectal resection syndrome, which combines stool fragmentation, urge incontinence, and incontinence. SA are responsible for anastomotic leakage rates of 0 to 29.2 per cent. Adding a colonic reservoir improves the functional results while reducing anastomotic complications. These colonic reservoir techniques include the colonic J pouch (CJP), transverse coloplasty (TC), and side-to-end anastomosis (STEA) procedures. The aim of this literature review was to compare the functional outcomes of these three techniques from a high level of evidence. CJP with a 4- to 6-cm reservoir is a good surgical option because it reduces functional impairments during the first year, and probably up to 5 years, but is not always feasible. TC appears to perform as well as CJP, is achievable in over 95 per cent of patients, but still with some doubts about a higher anastomotic leakage rate and worse functional outcomes. STEA appears equivalent to CJP in terms of morbidity and even better functional outcomes. STEA, with a terminal side segment size of 3 cm, is feasible in the majority of nonobese patients, combines good functional results, has low anastomotic leakage rates, and is easy to complete.

Abstract
The aim of this review is to characterize the functional results and "anterior resection syndrome" (ARS) after sphincter-saving surgery for rectal cancer. The purpose of sphincter-saving operations is to save the anal sphincters by avoiding the need for rectal abdomino-perineal resection with a permanent stoma. A variety of alternative techniques have been proposed and, today, ultra-low anterior resections of the rectum are commonplace. Inevitably rectal resections modify anorectal physiology. The backdrop of the functional asset for ultralow anterior resections is related to a small neorectal capacity with high endo-neorectal pressures that act together on a weakened sphincteric mechanism. Sometimes a defecation disorder called ARS may be induced and the patient experiences an extremely low quality of life. Impaired bowel function is usually provoked either by colonic dysmotility, neorectal reservoir dysfunction, anal sphincter damage or by a combination of these factors. Surgical technique defects can contribute to these possible causes: anastomotic ischemia, short length of the descending colon and stretching of neorectal mesentery may play a role. Unfortunately, there is no therapeutic algorithm or gold standard treatment that may be used for ARS. Nevertheless, it is rational to use conservative therapy first and then resort to surgery. Drugs, rehabilitative treatment and sacral neuromodulation may be used; after failure of conservative methods, surgical treatment can be considered.

Abstract
Between 25 and 80% of patients undergoing a low or very low anterior resection will suffer postoperatively, from a constellation of symptoms including fecal urgency, frequent bowel movements, bowel fragmentation and incontinence, collectively referred to as the low anterior resection syndrome (LARS). The etiology of LARS is multifactorial with the potential of sphincter injury during anastomosis construction, alterations in anorectal physiology, the development of a pudendal neuropathy, and a lumbar plexopathy with exacerbation of symptoms if there is associated anastomotic sepsis or the use of adjuvant and neoadjuavnt therapies. The symptoms of LARS may be obviated in part by the construction of a neorectal reservoir which may take the form of a colonic J-pouch, a transverse coloplasty, or a side-to-end anastomosis. This review outlines the factors contributing to LARS symptomatology along with the short- and medium-term functional results of comparative trials with the different types of neorectal reconstructions.
