Comparison of complications and bowel function among different reconstruction techniques after low anterior resection for rectal cancer: a systematic review and network meta-analysis. World J Surg Oncol 2023; 21:87. [PMID: 36899350 PMCID: PMC9999608 DOI: 10.1186/s12957-023-02977-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 02/27/2023] [Indexed: 03/12/2023] Open
Abstract
BACKGROUND Anastomosis for gastrointestinal reconstruction has been contentious after low anterior resection of rectal cancer for the past 30 years. Despite the abundance of randomized controlled trials (RCTs) on colon J-pouch (CJP), straight colorectal anastomosis (SCA), transverse coloplast (TCP), and side-to-end anastomosis (SEA), most studies are small and lack reliable clinical evidence. We conducted a systematic review and network meta-analysis to evaluate the effects of the four anastomoses on postoperative complications, bowel function, and quality of life in rectal cancer. METHODS We assessed the safety and efficacy of CJP, SCA, TCP, and SEA in adult patients with rectal cancer after surgery by searching the Cochrane Library, Embase, and PubMed databases to collect RCTs from the date of establishment to May 20, 2022. Anastomotic leakage and defecation frequency were the main outcome indicators. We pooled data through a random effects model in a Bayesian framework and assessed model inconsistency using the deviance information criterion (DIC) and node-splitting method and inter-study heterogeneity using the I-squared statistics (I2). The interventions were ranked according to the surface under the cumulative ranking curve (SUCRA) to compare each outcome indicator. RESULTS Of the 474 studies initially evaluated, 29 were eligible RCTs comprising 2631 patients. Among the four anastomoses, the SEA group had the lowest incidence of anastomotic leakage, ranking first (SUCRASEA = 0.982), followed by the CJP group (SUCRACJP = 0.628). The defecation frequency in the SEA group was comparable to those in the CJP and TCP groups at 3, 6, 12, and 24 months postoperatively. In comparison, the defecation frequency in the SCA group 12 months after surgery all ranked fourth. No statistically significant differences were found among the four anastomoses in terms of anastomotic stricture, reoperation, postoperative mortality within 30 days, fecal urgency, incomplete defecation, use of antidiarrheal medication, or quality of life. CONCLUSIONS This study demonstrated that SEA had the lowest risk of complications, comparable bowel function, and quality of life compared to the CJP and TCP, but further research is required to determine its long-term consequences. Furthermore, we should be aware that SCA is associated with a high defecation frequency.

Abstract
BACKGROUND Multiple trials have compared reconstruction techniques used following the resection of distal rectal cancers, including straight colorectal anastomosis (SCA), colonic J pouch (CJP), side-to-end anastomosis (SEA), and transverse coloplasty (TCP). The latest meta-analysis on the subject concluded that all the reservoir techniques produce equally good surgical and functional outcomes compared with SCA. Numerous trials have been published in this regard subsequently. Hence, a network analysis (NMA) was performed to rank these techniques. METHODS A literature search of MEDLINE, Embase, and the Cochrane Library from their inception until April 2021 was conducted to identify randomized trials. Functional and surgical outcome data were pooled. ORs and standardized mean differences (MDs) were used as pooled effect size measures. A frequentist NMA model was used. RESULTS Thirty-two trials met the eligibility criteria comprising 3072 patients. CJP showed better functional outcomes, such as low stool frequency and better incontinence score, both in the short term (stool frequency, MD -2.06, P < 0.001; incontinence, MD -1.17, P = 0.007) and intermediate term (stool frequency, MD -0.81, P = 0.021; incontinence MD -0.56, P = 0.083). Patients with an SEA (long-term OR 4.37; P = 0.030) or TCP (long-term OR 5.79; P < 0.001) used more antidiarrheal medications constantly. The urgency and sensation of incomplete evacuation favoured CJP in the short term. TCP was associated with a higher risk of anastomotic leakage (OR 12.85; P < 0.001) and stricture (OR 3.21; P = 0.012). CONCLUSION Because of its better functional outcomes, CJP should be the reconstruction technique of choice. TCP showed increased anastomotic leak and stricture rates, warranting judicious use.

Abstract
Purpose To assess the feasibility and short-term outcomes of neoadjuvant chemoradiotherapy (CCRT) followed by transanal total mesorectal excision assisted by single-port laparoscopic surgery (TaTME-SPLS) for low-lying rectal adenocarcinoma. Methods and materials A total of 23 patients with clinical stage II-III low-lying (from anal verge 0-8 cm) rectal adenocarcinoma who underwent neoadjuvant CCRT followed by TaTME-SPLS consecutively from December 2015 to December 2018, were enrolled into our study. Chi-squared testing and Student’s t testing were used to make parametric comparisons, and Fisher’s exact test or the Mann–Whitney U test were used to make nonparametric comparisons. Results Conversion rate in patients who underwent neoadjuvant CCRT followed by TaTME-SPLS was only 4%. The mean operation time was 366 min and the inter-sphincter resection (ISR) was done for 14 patients (60%). The mean number of lymph nodes harvested was 15. There was no surgical mortality, but the 30-day morbidity rate was 21% (5 patients were Clavien-Dindo I-II). Pathological complete response was 21.74% with 100% organ preservation and 100% clear distal margin after neoadjuvant CCRT followed by TaTME-SPLS. Conclusion TaTME-SPLS would be highly successful in lymph node negative and low T stage of low-lying rectal cancer patients who had pathological complete remission or high percentage of partial remission after neoadjuvant CCRT.

Abstract
Colorectal carcinoma is the second leading cause of cancer-related deaths in the United States, with rectal cancer accounting for approximately one third of newly diagnosed cases. Surgery remains the cornerstone of curative therapy, with total mesorectal excision being the standard of care. Although minimally invasive procedures might be appropriate for a subset of patients with early-stage, superficial tumors, the standard of care for medically operable patients with nonmetastatic rectal cancer includes a comprehensive multimodality approach of neoadjuvant chemoradiotherapy, surgery with total mesorectal excision, and systemic chemotherapy. However, the morbidity and mortality related to both local and distant organ relapse have remained challenging. In the present review, we have discussed the trial-level evidence that has shaped the current clinical practice patterns in the treatment of curable, nonmetastatic rectal cancer. In addition, we have discussed the anticipated results of ongoing clinical trials and outlined pragmatic opportunities for future investigation to optimize the current status quo and, hopefully, provide prospective validation of novel approaches in the treatment of rectal cancer.

Abstract
Background By improved surgical technique such as total mesorectal excision (TME), multimodal treatment and advances in imaging survival and an increased rate of sphincter preservation have been achieved in rectal cancer surgery. Minimal-invasive approaches such as laparoscopic, robotic and transanal-TME (ta-TME) enhance recovery after surgery. Nevertheless, disorders of bowel, anorectal and urogenital function are still common and need attention. Purpose This review aims at exploring the causes of dysfunction after anterior resection (AR) and the accordingly preventive strategies. Furthermore, the indication for low AR in the light of functional outcome is discussed. The last therapeutic strategies to deal with bowel, anorectal, and urogenital disorders are depicted. Conclusion Functional disorders after rectal cancer surgery are frequent and underestimated. More evidence is needed to define an indication for non-operative management or local excision as alternatives to AR. The decision for restorative resection should be made in consideration of the relevant risk factors for dysfunction. In the case of restoration, a side-to-end anastomosis should be the preferred anastomotic technique. Further high-evidence clinical studies are required to clarify the benefit of intraoperative neuromonitoring. While the function of ta-TME seems not to be superior to laparoscopy, case-control studies suggest the benefits of robotic TME mainly in terms of preservation of the urogenital function. Low AR syndrome is treated by stool regulation, pelvic floor therapy, and transanal irrigation. There is good evidence for sacral nerve modulation for incontinence after low AR.

Abstract
Introduction For more than the last 20 years, low anterior resection with total mesorectal excision (TME) is a gold standard for rectal cancer treatment. Oncological outcomes have improved significantly and now more and more reports of functional outcomes appear. Due to the close relationship between the rectum and pelvic nerves, bowel, bladder, and sexual function are frequently affected during TME. Methods A search for published data was performed using the MEDLINE database (from 1 January 2005 to 31 January 2015) to perform a systematic review of the studies that described anorectal, bladder, and sexual dysfunction following rectal cancer surgery. Methodological quality of the included studies was assessed using the MINORS criteria. Results Eighty-nine studies were eligible for analysis. Up to 76% of patients undergoing sphincter preserving surgery will have changes in bowel habits, the so-called "low anterior resection syndrome" (LARS). The duration of LARS varies between a few months and several years. Pre-operative radiotherapy, damage of anal sphincter and pelvic nerves, and height of the anastomosis are the risk factors for LARS. There is no evidence-based treatment available for LARS. Sexual function is more commonly affected after rectal surgery than after urinary function. The main cause of dysfunction is damage to pelvic nerves. Sexual and bladder functional outcomes in females are less well reported. Laparoscopic and robotic surgery allows better visualization of autonomic nerves and, therefore, more precise dissection and preservation. Conclusions It is important that rectal resection is standardized as much as possible, and that new functional outcome research use the same validated outcome questionnaires. This would allow for a high-quality meta-analysis.

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
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
AIM This multicentric prospective study aimed to investigate how postoperative complications after surgery for colorectal cancer affect patients' quality of life and satisfaction with care. METHOD One hundred and sixteen patients operated on for colorectal cancer were enrolled in this study. Patients answered three questionnaires about generic (EORTC QLQ-C30) and disease-specific (EORTC QLQ-CR29) quality of life and treatment satisfaction (EORTC IN-PATSAT32) at the time of admission and at 1 and 6 months after surgery. Non-parametric tests and linear multiple regression models were used for statistical analysis. RESULTS Twelve patients had complications requiring further surgery (anastomotic leakage, abdominal bleeding, abdominal wall sepsis, wound infection). Patients with complications that required surgery reported a worse score of physical function, emotional function and anxiety than patients without such complications 1 month after surgery. These patients judged their general satisfaction with the quality of care and doctors' interpersonal skills, technical skills, information provision and availability to be worse than in patients without such complications. The presence of postoperative psychiatric complications and anastomotic leakage were independent predictors of quality of life (β = -0.30, P = 0.004, and β = -0.42, P < 0.001). CONCLUSION In patients undergoing surgery for colorectal cancer, complications requiring any kind of surgical management significantly affected patients' perception of all doctor-related items suggesting an impairment of the entire surgeon-patient relationship. Convincing patients that 'zero risk' cannot be achieved in surgical practice is therefore a priority.

Abstract
PURPOSE This study evaluates the anorectal and genitourinary function of patients treated by preoperative short-term radiotherapy (RT) or chemoradiotherapy (CRT) followed by surgery and surgery alone for rectal cancer. METHODS For this study, a total of 613 patients, who were identified from a prospective rectal cancer database, underwent anterior resection of the rectum between October 2001 and December 2007. Standardized questionnaires were used to determine fecal incontinence, urinary, and sexual function. Relevant clinical variables were evaluated using univariate and multivariate analyses. Independent predictors of functional outcome were identified by a binary logistic regression analysis. RESULTS The data of 263 (43 %) patients were available for analysis. On multivariate analysis, neoadjuvant RT (P < 0.01) and low anterior resection (LAR) (P = 0.049) were associated with fecal incontinence. In univariate analysis, fecal incontinence was linked to preoperative neoadjuvant treatment (RT and/or CRT vs. LAR) (P < 0.01). The hazard ratio for developing fecal incontinence was 3.3 (1.6-6.8) for patients who received RT. One hundred twenty-five patients (51.2 %) experienced urinary incontinence following surgery, the majority of whom were female (P < 0.01). On univariate analysis, male sexual function was associated with age (P < 0.01), ASA class (P = 0.01) and LAR (P = 0.01). CONCLUSION Multimodal therapy of low rectal cancer increases the incidence of fecal incontinence and negatively affects sexual function. The potential benefits of RT or CRT need to be balanced against the risk of increased bowel dysfunction when determining the appropriate treatment for individual patients with rectal cancer.

Intestinal anastomosis is an essential part of surgical practice, and with it comes the inherent risk of complications including leaks, strictures, and bleeding, which result in significant morbidity and occasional mortality. Understanding the myriad of risk factors and the strength of the data helps guide a surgeon as to the safety of undertaking an operation in which a primary anastomosis is to be considered. This article reviews the risk factors, management, and outcomes associated with anastomotic complications.

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.

Abstract
The management of rectal cancer has transformed over the last 3 decades and continues to evolve. Some of these changes parallel progress made with other cancers: refinement of surgical technique to improve organ preservation, selective use of neoadjuvant (and adjuvant) therapy, and emergence of criteria suggesting a role for individually tailored therapy. Other changes are driven by fairly unique issues including functional considerations, rectal anatomic features, and surgical technical issues. Further complexity is due to the variety of staging modalities (each with its own limitations), neoadjuvant treatment alternatives, and competing strategies for sequencing multimodal treatment even for nonmetastatic disease. Importantly, observations of tumor response made in the era of neoadjuvant therapy are reshaping some traditionally held concepts about tumor behavior. Frameworks for prioritizing and integrating complex data can help to formulate treatment plans for patients.

Abstract
PURPOSE To evaluate the outcome of colonic J-pouches (CJP) and transverse colonic pouches (TCPs) after anterior resection for rectal cancer. METHOD Trials were located through Medline, Embase, the Cochrane Central Register of Controlled Trials, VIP and CNKI. Main end-points included functional outcomes, postoperative complications and anorectal physiological outcomes. RESULTS Of 120 articles, 34 compared CJP and TCP. Of these only six were randomized controlled trials (RCT), which fulfilled the inclusion criteria. These six included 648 patients, including 326 in the CJP group and 322 in the TCP group. There were no differences in the incidences of anastomotic leak [odds ratio 0.50, 95% confidence interval (CI) 0.21-1.18], chest infection (0.43, 0.09-2.00), wound infection (0.87, 0.33-2.30), anastomotic stricture (1.30, 0.44-3.84), fistula (0.64, 0.18-2.31).There were no difference in functional outcomes such as stool frequency [weighted mean difference (WMD) of -0.01, -0.30-0.27 at 6 months].There was no difference for anorectal physiology but heterogeneity existed: resting pressure (0.39, -1.76 to 2.55; 3.09, -0.04 to 6.23; 4.15, 2.21-6.094, at preoperation, 6 and 12 months,); squeeze pressure (-15.02, -46.14 to 16.10; -15.04, -37.04 to 6.97;0.83, -7.70 to 9.37 at preoperation, 6 and 12 months);(Neo)rectal threshold volume(8.49, 5.18-11.81; 27.13, -5.08 to 59.35, at preoperation and 6 months); Maximal (neo) rectal volume (-14.05, -36.60 to 8.50; 23.37, 2.65-44.09; -0.54, -0.91 to -0.18, at preoperation, 6 and at 12 months). CONCLUSIONS Transverse colonic pouch has similar results as CJP. As it is a safe, feasible, simple, technically easy and time-saving surgical procedure, TCP is a good candidate for wider clinical application.

Abstract
Many retrospective studies have found that the functional outcome after a low anterior resection for rectal cancer is better with colonic J-pouch reconstruction than with conventional straight anastomosis. This advantage was demonstrated in prospective, randomized trials and meta-analyses. However, despite its increasing popularity there are several areas of controversy about the use of the colonic J-pouch reconstruction. These issues include anastomotic leaks, the part of the colon used for the pouch, the pouch size, causes of difficulty in evacuation, indications (the optimum level of anastomosis), appropriateness for the elderly, and long-term (2 years or more after surgery) functional outcome. All relevant articles identified from MEDLINE databases were reviewed. The incidence of anastomotic leaks is apparently reduced by colonic J-pouch reconstruction. A 5-cm colonic J-pouch using the sigmoid colon increases the reservoir function without compromising evacuation, and provides better functional outcome than straight anastomosis, even 2 years or more after surgery, in patients whose anastomosis is less than 8 cm from the anal verge. Patients with ultralow anastomoses, less than 4 cm from the verge, appear to benefit the most. At a time when the indications for abdominoperineal excision appear to be reduced for low rectal cancer, the demand for colonic J-pouch reconstruction (the best technique in pouch operations) is therefore likely to increase.

Abstract
PURPOSE To identify the risk factors for perioperative morbidity in patients undergoing resection of primary rectal cancer, with a specific focus on the effect of neoadjuvant therapy. METHODS AND MATERIALS This exploratory analysis of prospectively collected data included all patients who underwent anterior resection/low anterior resection or abdominoperineal resection for primary rectal cancer between October 2001 and October 2006. The study endpoints were perioperative surgical and medical morbidity. Univariate and multivariate analyses of potential risk factors were performed. RESULTS A total of 485 patients were included in this study; 425 patients (88%) underwent a sphincter-saving anterior resection/low anterior resection, 47 (10%) abdominoperineal resection, and 13 (2%) multivisceral resection. Neoadjuvant chemoradiotherapy was performed in 100 patients (21%), and 168 (35%) underwent neoadjuvant short-term radiotherapy (5 x 5 Gy). Patient age and operative time were independently associated with perioperative morbidity, and operative time, body mass index >27 kg/m(2) (overweight), and resection type were associated with surgical morbidity. Age and a history of smoking were confirmed as independent prognostic risk factors for medical complications. Neoadjuvant therapy was not associated with a worse outcome. CONCLUSION The results of this prospective study have identified several risk factors associated with an adverse perioperative outcome after rectal cancer surgery. In addition, neoadjuvant therapy was not associated with increased perioperative complications.
