Abstract
PURPOSE Increasing importance has been attributed in recent years to the preservation of the pelvic autonomic nerves during rectal resection to achieve better functional results. In addition to improved surgical techniques, intraoperative neuromonitoring may be useful. METHODS This single-arm prospective study included 30 patients who underwent rectal resection performed with intraoperative neuromonitoring by recording the change in the tissue impedance of the urinary bladder and rectum after stimulation of the pelvic autonomic nerves. The International Prostate Symptom Score, the post-void residual urine volume and the Low Anterior Resection Syndrome Score (LARS score) were assessed during the 12-month follow-up period. RESULTS A stimulation-induced change in tissue impedance was observed in 28/30 patients (93.3%). In the presence of risk factors such as low anastomosis, neoadjuvant radiotherapy and a deviation stoma, an average increase of the LARS score by 9 points was observed 12 months after surgery (p = 0,04). The function of the urinary bladder remained unaffected in the first week (p = 0,7) as well as 12 months after the procedure (p = 0,93). CONCLUSION The clinical feasibility of the new method for pelvic intraoperative neuromonitoring could be verified. The benefits of intraoperative pelvic neuromonitoring were particularly evident in difficult intraoperative situations with challenging visualization of the pelvic nerves.

Abstract
Postoperative bowel dysfunction following restorative proctectomy, commonly referred to as Low Anterior Resection Syndrome (LARS), is a common long term sequela of rectal cancer treatment. While many of the established risk factors for LARS are non-modifiable, others may be well within the surgeon's control. Several pre-, intra-, and postoperative decisions may have a significant impact on postoperative bowel function. Some of these factors include the extent of surgical resection, surgical approach, choice of anastomotic reconstruction, and use of fecal diversion. This review article summarizes the available evidence regarding how surgical decision-making can affect postoperative bowel function.

Abstract
For patients with rectal cancer, the standard approach of chemotherapy, radiation therapy, and surgery (trimodality therapy) is associated with significant long-term toxicity and/or colostomy for most patients. Patient options focused on quality of life (QOL) have dramatically improved, but there remains limited guidance regarding comparative effectiveness. This systematic review and associated guidelines evaluate how various treatment strategies compare to each other in terms of oncologic outcomes and QOL. Cochrane and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology were used to search for prospective and retrospective trials and meta-analyses of adequate quality within the Ovid Medline database between January 1, 2012, and June 15, 2023. These studies informed the expert panel, which rated the appropriateness of various treatments in 6 clinical scenarios through a well-established consensus methodology (modified Delphi). The search process yielded 197 articles that advised voting. Increasing data have shown that nonoperative management (NOM) and primary surgery result in QOL benefits noted over trimodality therapy without detriment to oncologic outcomes. For patients with rectal cancer for whom total mesorectal excision would result in permanent colostomy or inadequate bowel continence, NOM was strongly recommended as usually appropriate. Restaging with tumor response assessment approximately 8 to 12 weeks after completion of radiation therapy/chemoradiation therapy was deemed a necessary component of NOM. The panel recommended active surveillance in the setting of a near-complete or complete response. In the setting of NOM, 54 to 56 Gy in 27 to 31 fractions concurrent with chemotherapy and followed by consolidation chemotherapy was recommended. The panel strongly recommends primary surgery as usually appropriate for a T3N0 high rectal tumor for which low anterior resection and adequate bowel function is possible, with adjuvant chemotherapy considered if N+. Recent data support NOM and primary surgery as important options that should be offered to eligible patients. Considering the complexity of multidisciplinary management, patients should be discussed in a multidisciplinary setting, and therapy should be tailored to individual patient goals/values.

Abstract
Background: Low anterior resection syndrome (LARS) is a bowel dysfunction following sphincter-sparing proctectomy. The occurrence of LARS may affect a patient's overall quality of life (QoL) after surgery. Current research was aimed to investigate related factors of LARS and major LARS in total mesorectal excision (TME) and its relationship with QoL. Methods: This study included patients who underwent TME at authors' institutes. LARS was evaluated with an LARS score. QoL was identified using the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire, version 3.0. Appropriate statistical methods were used to ascertain risk factors for LARS and major LARS and to analyze the relationships between QoL and LARS. The primary objective was to identify related factors of LARS and major LARS. The secondary objective was to examine the relationships between QoL and LARS. Results: Multivariable analysis identified neoadjuvant chemoradiotherapy (odds ratio [OR] 4.923, 95% confidence interval [CI] 2.335-10.379, P < .001), local anal distance from the lower edge of the tumor (OR 6.199, 95% CI 2.701-14.266, P < .001), and anastomotic leakage (OR 5.624, 95% CI 1.463-21.614, P = .012) as independent predictors for development of LARS. Meanwhile, neoadjuvant chemoradiotherapy (OR 4.693, 95% CI 1.368-16.107, P = .014) and local anal distance from the lower edge of the tumor (OR 4.935, 95% CI 1.332-18.285, P = .017) were dramatically correlated with development of major LARS in a multivariable analysis. In the major LARS group, statistically significant differences (P < .05) were ascertained, include physical functioning, role functioning, emotional functioning, social functioning, and global health. In addition, pain and diarrhea were evidently higher. Conclusions: Neoadjuvant chemoradiotherapy, local anal distance from the lower edge of the tumor, and anastomotic leakage correlated strongly with development of LARS, and neoadjuvant chemoradiotherapy and local anal distance from the lower edge of the tumor correlated strongly with development of major LARS. Meanwhile, the QoL of patients with major LARS was lower than that of patients with no/minor LARS.

Abstract
AIM The aim of this work was to evaluate the concordance between the low anterior resection syndrome (LARS) and preoperative LARS (POLARS) scores regarding the incidence of LARS in a Chilean population undergoing rectal surgery for cancer in a high-volume hospital. METHOD The LARS score questionnaire, following telephone requests, was used to determine the presence and severity of LARS. The POLARS score was calculated based on variables described previously. Correlations and qualitative and quantitative concordance were evaluated using Spearman's correlation coefficient, the kappa coefficient and the Bland-Altman plot with Lin's concordance correlation coefficient. RESULTS A total of 120 patients met the inclusion criteria: 37.5% underwent neoadjuvant radiotherapy, 61% underwent total mesorectal excision (TME) and 51.6% underwent ostomy. A total of 49% of patients did not present with LARS, whereas 28% had major LARS. The correlation between scales was poor, with a fair qualitative concordance to determine the presence/absence of LARS and a slight qualitative concordance to determine the degree of the intensity. The quantitative concordance was poor. CONCLUSION In the Chilean population, concordance between the LARS and POLARS scores was qualitatively fair to determine the presence/absence of the disease and qualitatively slight to determine the degree of intensity. We do not suggest using the POLARS score in the perioperative period in the Chilean population deliberately, as the score may help to determine the presence/absence of LARS but cannot determine its degree of intensity. Additional evaluations are required to determine the factors contributing to the degree of agreement between the scales.

Abstract
The present study aimed to evaluate the incidence and risk factors of severe low anterior resection syndrome (LARS) in patients with rectal cancer undergoing sphincter-preserving resection, and to provide the clinical basis and reference for the treatment of rectal cancer and the prevention of LARS. Studies on the incidence and risk factors for severe LARS in patients with rectal cancer undergoing sphincter-preserving resection were searched using PubMed, Embase, Cochrane Library, Scopus and Web of Science, according to the inclusion and exclusion criteria. After evaluating the study quality and extracting relevant data, RevMan 5.2 and STATA software were used to conduct a meta-analysis. A total of 12 articles were considered eligible for the present meta-analysis. Within these articles, there were 3,877 cases of sphincter-preserving resection for rectal cancer and 1,589 cases of severe LARS; the incidence of severe LARS was 40.99%. The results of the meta-analysis revealed that sex [female; odds ratio (OR), 6.54; 95% CI, 3.63-11.76; Z, 6.27; P<0.00001], radiotherapy and chemotherapy (OR, 3.45; 95% CI, 2.29-5.21; Z, 5.91; P<0.00001), total mesorectal excision (TME; OR, 4.39; 95% CI, 3.32-5.79; Z, 10.41; P<0.00001), and distance between tumor and anal margin (OR, 2.74; 95% CI, 0.86-8.72; Z, 1.70; P<0.00001) may be the risk factors for severe LARS.

Abstract
BACKGROUND & AIMS The benefit of radiotherapy for rectal cancer is based largely on a balance between a decrease in local recurrence and an increase in bowel dysfunction. Predicting postoperative disability is helpful for recovery plans and early intervention. We aimed to develop and validate a risk model to improve the prediction of major bowel dysfunction after restorative rectal cancer resection with neoadjuvant radiotherapy using perioperative features. METHODS Eligible patients more than 1 year after restorative resection following radiotherapy were invited to complete the low anterior resection syndrome (LARS) score at 3 national hospitals in China. Clinical characteristics and imaging parameters were assessed with machine learning algorithms. The post-radiotherapy LARS prediction model (PORTLARS) was constructed by means of logistic regression on the basis of key factors with proportional weighs. The accuracy of the model for major LARS prediction was internally and externally validated. RESULTS A total of 868 patients reported a mean LARS score of 28.4 after an average time of 4.7 years since surgery. Key predictors for major LARS included the length of distal rectum, anastomotic leakage, proximal colon of neorectum, and pathologic nodal stage. PORTLARS had a favorable area under the curve for predicting major LARS in the internal dataset (0.835; 95% CI, 0.800-0.870, n = 521) and external dataset (0.884; 95% CI, 0.848-0.921, n = 347). The model achieved both sensitivity and specificity >0.83 in the external validation. In addition, PORTLARS outperformed the preoperative LARS score for prediction of major events. CONCLUSIONS PORTLARS could predict major bowel dysfunction after rectal cancer resection following radiotherapy with high accuracy and robustness. It may serve as a useful tool to identify patients who need additional support for long-term dysfunction in the early stage. CLINICALTRIALS gov, number NCT05129215.

Abstract
PURPOSE Our aim was to perform a propensity score-matched study to compare the long-term functional outcomes and quality of life following intersphincteric resection vs. low anterior resection (LAR) with very low anastomosis. METHODS Patients who underwent intersphincteric resection or low anterior resection with low anastomosis (≤ 4 cm from the anal verge) for rectal cancer between January 2017 and June 2020 were retrospectively included. A propensity score-matching process was performed. Functional outcomes and quality of life were assessed using the European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L), EORC-QLQ C30, EORC-QLQ CR29, Low Anterior Resection Syndrome (LARS), Wexner, and International Prostate Symptom Score (IPSS) questionnaires. The primary outcome was the presence of LARS at least 12 months after surgery. The second outcome was the postoperative quality of life of included patients. RESULTS After propensity matching, 128 patients were included, including 58 males and 70 females with a median age of 59.5. Patients in the intersphincteric resection group showed a higher incidence of incontinence to flatus (32.8% versus 14.0%, p = 0.043) and stools (42.2% versus 21.9%, p = 0.046), pain/discomfort (25.0% versus 7.8%, p = 0.001), and bowel dysfunction, while the LARS scores (15.0 versus 13.2, p = 0.461) and major LARS rates (26.6% versus 14.1%, p = 0.078) were comparable in both groups. CONCLUSION ISR leads to increased bowel incontinence rate and increased anal pain, without affecting the grade of low anterior resection syndrome, fecal urgency, and clustering. LAR might be the preferred sphincteric-preserving approach when negative resection margins and a safe anastomosis are guaranteed. Patients should be fully informed about potential functional impairment after sphincter-preservation procedures.

Abstract
PURPOSE Anorectal, sexual, and urinary dysfunction are common issues after rectal cancer surgery, although seldom explored. The primary aim of this study was to investigate postoperative anorectal functional results. METHODS Patients with mid/low-rectal cancer treated with transanal TME (TaTME) with primary anastomosis with/without diverting stoma between 2015 and 2020 were reviewed and selected if they had a minimum follow-up of 6 months (from the primary procedure or stoma reversal). Patients were interviewed using validated questionnaires and the primary outcome was bowel function based on Low Anterior Resection Syndrome (LARS) scores. Statistical analyses were performed to identify clinical/operative variables correlated with worse outcomes. A random forest (RF) algorithm was computed to classify patients at a greater risk of minor/major LARS. RESULTS Ninety-seven patients were selected out of 154 TaTME performed. Overall, 88.7% of the patients had a protective stoma and 25.8% reported major LARS at mean follow-up of 19.0 months. Statistical analyses documented that age, operative time, and interval to stoma reversal correlated with LARS outcomes. The RF analysis disclosed worse LARS symptoms in patients with longer operative time (> 295 min) and stoma reversal interval (> 5.6 months). If the interval ranged between 3 and 5.6 months, older patients (> 65 years) reported worse outcomes. Finally, no statistical difference was documented when comparing the rate of minor/major LARS in the first 27 cases versus others. CONCLUSION One-quarter of the patients developed major LARS after TaTME. An algorithm based on clinical/operative variables, such as age, operative time, and time to stoma reversal, was developed to identify categories at risk for LARS symptoms.

Abstract
BACKGROUND Low anterior resection syndrome (LARS) is a common complication of anus-preserving surgery in patients with colorectal cancer, which significantly affects patients' quality of life. AIM To determine the relationship between the incidence of LARS and patient quality of life after colorectal cancer surgery and to establish a LARS prediction model to allow perioperative precision nursing. METHODS We reviewed the data from patients who underwent elective radical resection for colorectal cancer at our institution from April 2013 to June 2020 and completed the LARS score questionnaire and the European Organization for Research and Treatment of Cancer Core Quality of Life and Colorectal Cancer Module questionnaires. According to the LARS score results, the patients were divided into no LARS, mild LARS, and severe LARS groups. The incidence of LARS and the effects of this condition on patient quality of life were determined. Univariate and multivariate analyses were performed to identify independent risk factors for the occurrence of LARS. Based on these factors, we established a risk prediction model for LARS and evaluated its performance. RESULTS Among the 223 patients included, 51 did not develop LARS and 171 had mild or severe LARS. The following quality of life indicators showed significant differences between patients without LARS and those with mild or severe LARS: Physical, role, emotional, and cognitive function, total health status, fatigue, pain, shortness of breath, insomnia, constipation, and diarrhea. Tumor size, partial/total mesorectal excision, colostomy, preoperative radiotherapy, and neoadjuvant chemotherapy were identified to be independent risk factors for LARS. A LARS prediction model was successfully established, which demonstrated an accuracy of 0.808 for predicting the occurrence of LARS. CONCLUSION The quality of life of patients with LARS after colorectal cancer surgery is significantly reduced.

Abstract
PURPOSE Oncological outcomes following rectal cancer surgery have improved significantly over recent decades with lower recurrences and longer overall survival. However, many of the patients experienced low anterior resection syndrome (LARS). This study identified the prevalence and risk factors associated with the development of LARS. METHODS This cross-sectional study involved patients who were diagnosed with rectal cancer and had undergone sphincter-preserving low anterior resection from January 2011 to December 2020. Upon clinic follow-up, patients were asked to complete an interviewed based questionnaire (LARS score) designed to assess bowel dysfunction after rectal cancer surgery. RESULTS Out of 76 patients, 25 patients (32.9%) had major LARS, 10 patients (13.2%) had minor LARS, and 41 patients (53.9%) had no LARS. The height of tumor from anal verge showed an association with the development of major LARS (P=0.039). Those patients with less than 8 cm tumor from anal verge had an increased risk of LARS by 3 times compared to those with 8 cm and above (adjusted odds ratio, 3.11; 95% confidence interval, 1.06-9.13). CONCLUSION Results from our study show that low tumor height was a significant risk factor that has a negative impact on bowel function after surgery. The high prevalence of LARS emphasizes the need for study regarding risk factors and the importance of understanding the pathophysiology of LARS, in order for us to improve patient bowel function and quality of life after rectal cancer surgery.

Abstract
BACKGROUND Rectal cancer is frequent and often treated with sphincter-saving procedures that may cause LARS, a syndrome characterized by symptoms of bowel disfunction that may severely affect quality of life. LARS is common, but its pathogenesis is mostly unknown. The aim of this study is to assess the incidence of LARS and to identify potential risk factors. METHODS We performed an observational retrospective single center analysis. The following data were collected and analyzed for each patient: demographics, tumor-related data, and intra- and peri-operative data. Statistical analysis was conducted, including descriptive statistics and multivariate logistic regression to identify independent risk factors. RESULTS Total LARS incidence was 31%. Statistically significant differences were found in tumor distance from anal verge, tumor extension (pT and diameter) and tumor grading (G). Multivariate analysis identified tumor distance from anal verge and tumor extension as an independent predictive factor for both major and total LARS. Adjuvant therapy, although not significant at univariate analysis, was identified as an independent predictive factor. Time to stoma closure within 10 weeks seems to reduce incidence of major LARS. CONCLUSIONS bold LARS affects a considerable portion of patients. This study identified potential predictive factors that could be useful to identify high risk patients for LARS.

Assessing the role of anastomotic level in low anterior resection (LAR) surgery among rectal cancer patients in the development of LAR syndrome: a systematic review study. BMC Surg 2023; 23:263. [PMID: 37653424 PMCID: PMC10472547 DOI: 10.1186/s12893-023-02166-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2023] [Accepted: 08/24/2023] [Indexed: 09/02/2023] Open
Abstract
BACKGROUND The etiology of LARS has not been elaborated on clearly. Studies have reported neoadjuvant therapy, low-lying rectal cancers, adjuvant therapy and anastomotic leakage as risk factors for the development of LARS. Anastomotic level has also been proposed as a possible risk factor; However, there have been conflicting results. This study aims to evaluate the role of the level of anastomosis as a potential risk factor for the development of LARS. METHOD A systematic literature search was conducted on Pubmed, Scopus, Embase, and Web of Science databases using Mesh terms and non-Mesh terms from 2012 to 2023. Original English studies conducted on rectal cancer patients reporting of anastomotic level and LARS status were included in this study. Eligible studies were assessed regarding quality control with Joanna-Briggs Institute (JBI) questionnaires. RESULTS A total of 396 articles were found using the research queries, and after applying selection criteria 4 articles were selected. A sample population of 808 patients were included in this study with a mean age of 61.51 years with male patients consisting 59.28% of the cases. The Mean assessment time was 15.6 months which revealed a mean prevalence of 48.89% for LAR syndrome. Regression analysis revealed significantly increased risk of LAR syndrome development due to low anastomosis level in all 4 studies with odds ratios of 5.336 (95% CI:3.197-8.907), 3.76 (95% CI: 1.34-10.61), 1.145 (95% CI: 1.141-2.149) and 2.11 (95% CI: 1.05-4.27) for low anastomoses and 4.34 (95% CI: 1.05-18.04) for ultralow anastomoses. CONCLUSIONS LARS is a long-term complication following surgery, leading to reduced quality of life. Low anastomosis level has been reported as a possible risk factor. All of the studies in this systematic review were associated with an increased risk of LARS development among patients with low anastomosis.

Abstract
PURPOSE Identifying tumor location is important in colorectal tumor resection. Preoperative endoscopic India ink marking is a widespread practice, but local injection of ink is an unstable procedure. Although it is often invisible, the ink may be sprayed into the peritoneal cavity and contaminate the surgical field. At our hospital, we introduced fluorescent clip marking (FCM) using the Zeoclip FS®, an endoscopic clip developed using near-infrared fluorescent resin. We tested the usefulness of FCM by retrospectively comparing cases in which FCM was used with cases in which conventional ink marking was used. METHODS We enrolled 305 patients with colorectal tumors who underwent colorectal surgery after preoperative marking from January 2017 to April 2022. We classified the patients into the FCM group (86 patients) and the India ink tattoo group (219 patients). Endoscopic marking was completed in the FCM group by the day before surgery, and fluorescence was evaluated during surgery with a fluorescent laparoscopic system. Patient backgrounds, marking visibility, adverse effects, and early postoperative results were retrospectively compared between groups. RESULTS Marking was visually confirmed in 80 patients in the FCM group (93.02%) and in 166 patients in the India ink tattoo group (75.80%) (p = 0.0006). In the group with India ink tattoos, contamination of the surgical field was observed in seven cases (3.20%). No adverse events were observed in the FCM group. CONCLUSION In colorectal surgery, FCM provides better visibility than the conventional India ink tattooing method and is a simple and safe marking method.

Abstract
AIMS The impact of neoadjuvant therapy on the functional outcome of patients with resectable rectal cancer is still controversial. The aim of the present study was to explore the effects of neoadjuvant therapy on anorectal function (ARF), urinary function and sexual function in relevant patients. MATERIALS AND METHODS PubMed, Embase, Web of Science and the Cochrane Library were searched systematically. All English-language studies, published from January 2000 to July 2021, that explored the (postoperative) effects of neoadjuvant therapy versus upfront surgery on ARF, urinary function and sexual function of patients were included (PROSPERO 2021: CRD42021281617). RESULTS The data in this study were derived from 37 articles based on 33 studies; in total, 17 917 patients were enrolled. The meta-analysis revealed that the incidence of anorectal dysfunction in the neoadjuvant therapy group was significantly higher than that in the group of upfront surgery, which was manifested by a higher incidence of major low anterior resection syndrome (odds ratio = 3.09, 95% confidence interval = 2.48, 3.84; P < 0.001), reduction of mean squeeze pressure and mean resting pressure, and other manifestations, including clustering of stools, incontinence, urgency and use of pads. With the extension of follow-up time, the adverse effects of neoadjuvant therapy on major low anterior resection syndrome existed. Compared with patients undergoing upfront surgery, neoadjuvant therapy increased the risk of urinary incontinence (odds ratio = 1.31, 95% confidence interval = 1.00, 1.72; P = 0.05) and erectile dysfunction (odds ratio = 1.77, 95% confidence interval = 1.27, 2.45; P < 0.001). CONCLUSION Compared with upfront surgery, neoadjuvant therapy is not only associated with impairment of ARF, but also with increased incidence of urinary incontinence and male erectile dysfunction. However, the influence of confounding factors (e.g. surgical method, tumour stage) needs to be considered.

Abstract
BACKGROUND Low anterior resection syndrome (LARS) is a common postoperative complication in patients with colorectal cancer, which seriously affects their postoperative quality of life. At present, the aetiology of LARS is still unclear, but some risk factors have been studied. Accurate prediction and early management of medical intervention are keys to improving the quality of life of such high-risk patients. OBJECTIVES Based on machine-learning methods, this study used the follow-up results of postoperative patients with colorectal cancer to develop prediction models for LARS and conducted a comparative analysis between the different models. METHODS A total of 382 patients diagnosed with colorectal cancer and undergoing surgery at West China Hospital from April 2017 to December 2020 were retrospectively selected as the development cohort. Logistic regression, support vector machine, decision tree, random forest and artificial neural network algorithms were used to construct the prediction models of the obtained dataset. The models were internally validated using cross-validation. The area under the curve and Brier score measures were used to evaluate and compare the differentiation and calibration degrees of the models. The sensitivity, specificity, positive predictive value and negative predictive value of the different models were described for clinical use. RESULTS A total of 342 patients were included, the incidence of LARS being 47.4% (162/342) during the six-month follow-up. After feature selection, the factors influencing the occurrence of LARS were found to be location, distance, diverting stoma, exsufflation and surgical type. The prediction models based on five machine-learning methods all showed acceptable performance. CONCLUSIONS The five models developed based on the machine-learning methods showed good prediction performance. However, considering the simplicity of clinical use of the model results, the logistic regression model is most recommended. The clinical applicability of these models will also need to be evaluated with external cohort data.

BACKGROUND Most patients with mid and low rectal cancer passively react to bowel symptoms after sphincter-preserving surgery (SPS), and their self-management behaviors are scarce in the Chinese patient population. OBJECTIVE The aim of this study was to evaluate the effect of a self-management program for bowel symptoms in patients with mid and low rectal cancer after SPS. METHODS A convenient sampling method was used to recruit patients with mid and low rectal cancer after SPS in gastric wards from 2 tertiary hospitals in Beijing, China. Ninety-five patients (intervention, n = 47; control, n = 48) were recruited. The intervention group received a predetermined self-management program plus routine postoperative care; the control group received only routine care in the ward. Data on patients' bowel symptoms, quality of life, and bowel symptom self-management behaviors were collected at baseline and at 3 and 6 months postoperatively using questionnaires. A generalized estimating equation was adopted to examine group effect and time effect. RESULTS Bowel symptoms and quality of life in both the intervention and control groups of patients improved significantly 6 months after SPS compared with baseline (time effect, P < .001). The total score of patients' bowel symptom self-management behaviors and the score of the therapeutic domain increased significantly in the intervention group compared with those in the control group (group effect, P = .009). CONCLUSIONS Self-management programs could help prompt patients' self-management behaviors, but the extent to which they impact patients' bowel symptoms requires further investigation. IMPLICATIONS FOR PRACTICE The bowel dysfunction self-management program could alter the behavior of patients. It also effectively improves self-management strategies for bowel symptoms.

Defunctioning stoma in rectal cancer surgery - A risk factor for Low Anterior Resection Syndrome? EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 48:2518-2524. [PMID: 35798597 DOI: 10.1016/j.ejso.2022.06.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 06/04/2022] [Accepted: 06/19/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND In rectal cancer surgery the formation of a defunctioning stoma is common in order to reduce the consequences of an anastomotic leakage. The role of a defunctioning stoma and time to stoma reversal, in relation to major Low Anterior Resection Syndrome (LARS) in the long-term perspective, is still unclear. The aim of the study was to investigate the association between a defunctioning stoma and long-term bowel function. METHOD Patients who underwent curative rectal cancer surgery between 2007 and 2013 in Stockholm county, Sweden, who had no history of anastomotic leakage, without a remaining stoma, free of cancer and alive in April 2017 were eligible for the study. The exposures were (i) use of defunctioning stoma at cancer surgery and (ii) time to stoma reversal. Main outcome was major LARS with information retrieved from the LARS score questionnaire. Multivariable logistic regression model was used to calculate odds ratios (OR) primary comparing major LARS to no LARS. RESULTS A total of 430 patients were included in analysis. The mean follow-up time was 6.7 years after surgery (range 3.4-10.7 years). The use of a defunctioning stoma was associated to major LARS with an adjusted OR of 2.43 (95% CI 1.14-5.20) when compared to no stoma. There were no evident associations between time to stoma reversal and the risk of major LARS. CONCLUSION This study indicates that the presence of a defunctioning stoma is associated with impaired bowel function in the long-term perspective, while failing to show any clear association to time to stoma reversal.

Abstract
BACKGROUND Low anterior resection syndrome is common after sphincter-sparing surgery, but it is unclear to what extent anastomotic leakage after anterior resection contributes to this condition. OBJECTIVE The aim of this study is to assess the long-term effect of anastomotic leakage on the occurrence of major low anterior resection syndrome. DESIGN This is a retrospective observational cohort study evaluating low anterior resection syndrome 4 to 11 years after index surgery. After propensity score-matching using the covariates sex, age, tumor stage, comorbidity, neoadjuvant treatment, extent of mesorectal excision, and defunctioning stoma at index surgery, the effect of anastomotic leakage on low anterior resection syndrome was investigated using relative risk and 95% CI. SETTINGS This multicenter study included patients from 15 Swedish hospitals between 2007 and 2013. PATIENTS Patients who underwent anterior resection for rectal cancer were included. MAIN OUTCOME MEASURES Outcome measures included patient-reported major low anterior resection syndrome, obtained via a postal questionnaire that included a question on stoma status. RESULTS Among 1099 patients, 653 (59.4%) responded in at a median of 83.5 (interquartile range 66 to 110) months postoperatively. After excluding patients with residual stoma or incomplete responses, 544 remained; of these, 42 had anastomotic leakage. Patients with anastomotic leakage were more likely to have major low anterior resection syndrome (66.7% [28/42]) than patients without leakage (45.8% [230/502]). After matching, anastomotic leakage was significantly related to major low anterior resection syndrome (relative risk 2.3; 95% CI 1.4-3.9) and the individual symptom of urgency (relative risk 2.1; 95% CI 1.1-4.1). LIMITATIONS This study was limited by its retrospective observational study design. CONCLUSIONS In long-term follow-up, major low anterior resection syndrome is common after anterior resection for rectal cancer. Anastomotic leakage appears to increase the risk of major low anterior resection syndrome, with urgency as a major contributing symptom. See Video Abstract at http://links.lww.com/DCR/B868 .

Abstract
BACKGROUND Surgical and systemic therapies continue to advance, enabling restorative resections for distal rectal cancer. These operations are associated with low anterior resection syndrome. Recent studies with methodological and size limitations have investigated the incidence of low anterior resection syndrome after anterior resection. However, the long-term trajectory of low anterior resection syndrome and its effect on health-related quality of life remain unclear. OBJECTIVE The purpose of this study was to assess the impact of anterior resection and reversal of ileostomy on long-term health-related quality of life and low anterior resection syndrome. DESIGN Patient demographics were analyzed alongside low anterior resection syndrome and health-related quality-of-life qualitative scores (EORTC-QLQ-C30) obtained through cross-sectional postal questionnaires. SETTING Patients who underwent anterior resection of the rectum for cancer with defunctioning ileostomy between 2003 and 2016 at 2 high-volume centers in the United Kingdom were identified, excluding those experiencing anastomotic leakage. PATIENTS Among 478 eligible patients, 311 (65.1%) participated at a mean of 6.5 ± 0.2 years after anterior resection. Demographics and neoadjuvant chemoradiotherapy rates were similar ( p > 0.05) between participants and nonparticipants. RESULTS The percentage of patients who experienced major low anterior resection syndrome was 53.4% (166/311). Health-related quality-of-life functional domain scores improved in the years after reversal of ileostomy, with significant changes in constipation ( p = 0.01), social function ( p = 0.03), and emotional scores ( p = 0.02), as well as a reduction in the prevalence of major low anterior resection syndrome ( p = 0.003). LIMITATIONS The main limitation of this study was that the data collected were cross-sectional rather than longitudinal, and that nonresponders may have had worse cancer symptoms. CONCLUSIONS In this first large-scale study assessing long-term function after anterior resection and reversal of ileostomy, there is a linear improvement in major low anterior resection syndrome beyond 6 years, alongside improvements in key quality-of-life measures.

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
PURPOSE This study aims to identify the independent risk factors in the low anterior resection syndrome (LARS) after surgery for colorectal cancer (CRC). METHOD This was a retrospective, single-institution study in the Second Affiliation Hospital of Dalian Medical University, China. Patients underwent sphincter-preserving low anterior resection with total or partial mesorectal resection (with or without protective ileostomy) and completed a self-filled questionnaire over the phone to assess postoperative bowel dysfunction from January 2017 to December 2019. The predictors of LAR were evaluated using univariate and multivariate analyses. RESULT The study population was 566 patients, 264 (46.64%), 224 (39.58%), and 78 (13.78%) patients with no, minor, and major LARS, respectively. In the univariate analysis, independent factors such as tumor location and size, anastomotic height, protective ileostomy, post-operation chemoradiotherapy, tumor T stage, lymphatic nodal metastasis classification, surgery duration, and time interval for closure of stoma were significantly associated with LARS points while we found the tumor T stage and lymphatic nodal metastasis classification as the new independent risk factors compared with the last decade studies. In the multivariate analysis, factors such as low and middle tumor location and protective ileostomy, and post operation treatment, nodal metastasis classification were the independent risk factors for major LARS. CONCLUSION The new independence risk factors were tumor T stage and lymphatic nodal metastasis status in univariate analysis in our study, with anastomotic height, low and middle tumor location, protective ileostomy, post-operation chemoradiotherapy, nodal metastasis status increasing LARS point in multivariate analysis after surgery for CRC.

Abstract
OBJECTIVE We aimed to better understand the longitudinal course of low anterior resection syndrome (LARS) to guide patient expectations and identify those at risk of persisting dysfunction. SUMMARY BACKGROUND DATA LARS describes disordered bowel function after rectal resection that significantly impacts quality of life. METHODS MEDLINE, EMBASE, CENTRAL, and CINAHL databases were systematically searched for studies that enrolled adults undergoing anterior resection for rectal cancer and used the LARS score to assess bowel function at ≥2 postoperative time points. Regression analyses were performed on deidentified patient-level data to identify predictors of change in LARS score from baseline (3-6months) to 12-months and 18-24 months. RESULTS Eight studies with a total of 701 eligible patients were included. The mean LARS score improved over time, from 29.4 (95% confidence interval 28.6-30.1) at baseline to 16.6 at 36 months (95% confidence interval 14.2%-18.9%). On multivariable analysis, a greater improvement in mean LARS score between baseline and 12 months was associated with no ileostomy formation [mean difference (MD) -1.7 vs 1.7, P < 0.001], and presence of LARS (major vs minor vs no LARS) at baseline (MD -3.8 vs -1.7 vs 5.4, P < 0.001). Greater improvement in mean LARS score between baseline and 18-24 months was associated with partial mesorectal excision vs total mesorectal excision (MD-8.6 vs 1.5, P < 0.001) and presence of LARS (major vs minor vs no LARS) at baseline (MD -8.8 vs -5.3 vs 3.4, P < 0.001). CONCLUSIONS LARS improves by 18 months postoperatively then remains stable for up to 3 years. Total mesorectal excision, neoadjuvant radiotherapy, and ileostomy formation negatively impact upon bowel function recovery.

Abstract
PURPOSE Current low anterior resection syndrome (LARS) score is lagging behind and only based on clinical symptoms patient described. Preoperative imaging indicators which can be used to predict LARS is unknown. We proposed preoperative MRI parameters for identifying major LARS. METHODS Patients receiving curative restorative anterior resection from Sept. 2007 to Sept. 2015 were collected to complete LARS score (median 75.7 months since surgery). MRI measurements associated with LARS were tested, and a multivariate logistic model was conducted for predicting LARS. Receiver operating characteristic curve was used to evaluate the model. RESULTS Two hundred fifty-five patients undergoing neoadjuvant chemoradiotherapy and 72 patients undergoing direct surgery were enrolled. The incidence of major LARS in NCRT group was significantly higher (53.3% vs.34.7%, P = 0.005). In patients with neoadjuvant chemoradiotherapy, the thickness of ARJ (TARJ), the distance between the tumor's lower edge and anal rectal joint (DTA), and sex were independent factors for predicting major LARS; ORs were 0.382 (95% CI, 0.198-0.740), 0.653 (95% CI, 0.565-0.756), and 0.935 (95% CI, 0.915-0.955). The AUC of the multivariable model was 0.842 (95% CI, 0.794-0.890). In patients with direct surgery, only DTA was the independent factor for predicting major LARS; OR was 0.958 (95% CI, 0.930-0.988). The AUC was 0.777 (95% CI: 0.630-0.925). CONCLUSIONS Baseline MRI measurements have the potential to predict major LARS in rectal cancer, which will benefit the decision-making and improve patients' life quality.

Abstract
Background Total mesorectal excision (TME) represents the “gold standard” of rectal cancer surgery. In locally advanced lesions neoadjuvant treatments (e.g. radiotherapy-nRT, radio chemotherapy-cnRT) have been shown to improve TME oncological results, reducing local recurrences rate. Nevertheless, these treatments have significant functional consequences impacting patients’ quality of life (QoL). The resulting syndrome is known as Low Anterior Resection Syndrome (LARS). The purpose of this work was to evaluate the association between risk factors and the development of LARS in a prospective series of laparoscopic sphincter-saving TME. Methods The study was conducted as a retrospective observational epidemiological study of a prospective database, including all patients undergoing laparoscopic anterior resection surgery for rectal cancer at our Unit from 1st January 2013 to 31st May 2018. The diagnosis of LARS was performed using the LARS Score. We classified risk factors in patient-related, pre-, intra- and post-operative factors. Results The sample included 153 consecutive patients. Forty-one were affected by “low” rectal cancer, 74 by “middle” rectal cancer, 38 by “high” rectal cancer. The prevalence of overall LARS (major LARS + minor LARS) in our series was 35.9% (55/153 cases). Association between nRT and overall/major LARS was significant (respectively p = 0.03 and 0.02). Distal localization of tumor was also significantly associated with LARS [overall LARS (p = 0.03), major LARS (p = 0.014)]. Conclusions In our study, neoadjuvant radiotherapy and tumor localization resulted independent risk factors for LARS after laparoscopic sphincter-saving TME. Tumor localization in the “middle” and “high” rectum resulted a protective factor compared to the localization in “low” rectum.

Abstract
Background: Anterior resection is a common surgical approach used in rectal cancer surgery; however, this procedure is known to cause bowel injury and dysfunction. Neoadjuvant therapy is widely used in patients with locally advanced rectal cancer. In this study, we determined the effect of preoperative radiotherapy on long-term bowel function in patients who underwent anterior resection for treatment of rectal cancer. Methods: We performed a comprehensive literature search of the PubMed, Embase, Web of Science, and the Cochrane Library databases. A random-effects model was used in the meta-analysis by the Review Manager software, version 5.3. Results: This systematic review and meta-analysis included 12 studies, which used low anterior resection syndrome score with a total of 2349 patients. Based on them, we concluded that low anterior resection syndrome was significantly more common in the preoperative radiotherapy group (odds ratio 3.59, 95% confidence interval 2.68-4.81, P < .00001) and that major low anterior resection syndrome also occurred significantly more frequently in the preoperative radiotherapy group (odds ratio 3.28, 95% confidence interval 2.05-5.26, P < .00001). Subgroup analyses of long-course radiation, total mesorectal excision, and non-metastatic tumors were performed, and the results met the conclusions of the primary outcomes. Conclusions: Preoperative radiotherapy negatively affects long-term bowel function in patients who undergo anterior resection for rectal cancer.

Abstract
Sphincter preservation and organ restoration during rectal cancer surgery avoids permanent stoma creation and diminishes psychosocial damages. However, decreased rectal volumes and sphincter dysfunction—including pelvic nerve damage—results in low anterior resection syndrome, as well as urinary and sexual dysfunction after rectal resection. Bowel habit changes such as fecal incontinence, fecal urgency, frequent bowel movements, clustered stools, and difficulties in bowel emptying can be treated using medications, pelvic floor rehabilitation, sacral neuromodulation, or neorectal reservoir reconstruction. Pelvic nerve damage resulting from superior and inferior hypogastric plexi during sphincter-preserving rectal cancer surgery can induce urologic and sexual dysfunctions. Preoperative voiding difficulty, perioperative blood loss, and autonomic nerve injury are considered independent risk factors for postoperative urinary dysfunction. Retrograde ejaculation and erectile dysfunction, female dyspareunia, and vaginal dryness are manifestations of sexual dysfunction resulting from autonomic nerve injury during rectal cancer surgery. Multifactorial causes for functional outcomes after sphincter- preserving surgeries are considered to improve patient’s quality of life with acceptable oncologic outcomes in the treatment of rectal cancer patients.

Abstract
Surgery remains the cardinal treatment in colorectal cancers but changes in bowel habits after rectal cancer surgery are common and disabling conditions that affect patients' quality of life. Low anterior resection syndrome is a disorder of bowel function after rectal resection resulting in a lowering of the QoL and recently has been defined by an international working group not only by specified symptoms but also by their consequences. This review aims to explore an extensive bibliographic research on preventive strategies for LARS. All "modifiable variables," quantified by the LARS Score, such as type of anastomosis, neoadjuvant therapy, surgical strategy, and diverting stoma, were evaluated, while "non-modifiable variables" such as age, sex, BMI, ASA, preoperative TMN, tumor height, and type of mesorectal excision were excluded from the comparative analysis. The role of defunctioning stoma, local excision, neoadjuvant radiotherapy, and non operative management seems to significantly affect risk of LARS, while type of anastomosis and surgical TME approach do not impact on LARS incidence or gravity in the long term period. Although it is established that some variables are associated with a greater onset of LARS, in clinical practice, technical difficulties and oncological limits often make difficult the application of some prevention plans. Transtomal irrigations, intraoperative neuromonitoring, pelvic floor rehabilitation before stoma closure, and early transanal irrigation represent new arguments of study in preventive strategies which could, if not eliminate the symptoms, at least mitigate them.

Abstract
Bowel dysfunction after restorative proctectomy, commonly referred to as Low Anterior Resection Syndrome (LARS), is a common long-term sequela of rectal cancer treatment that has a significant impact on quality of life. While the pathophysiology of LARS is poorly understood, its underlying cause is likely multifactorial, and there are numerous patient, tumor, and treatment-level factors associated with its development. In accordance with these risk factors, several strategies have been proposed to mitigate LARS postoperatively, including modifications in the technical approach to restorative proctectomy and advancements in the multidisciplinary care of rectal cancer. Furthermore, a clinically applicable pre-operative nomogram has been developed to estimate the risk of LARS postoperatively, which may help in counseling patients before surgery. The management of LARS begins with identifying those who manifest symptoms, as postoperative bowel dysfunction often goes unrecognized. This goal is best achieved with the systematic screening of patients using validated Patient-Reported Outcome Measures. Once a patient with LARS is identified, conservative management strategies should be implemented. When available, a dedicated LARS nurse and/or multidisciplinary team can be an invaluable resource in engaging patients and educating them regarding LARS self-care. If symptoms of LARS persist or worsen over time despite conservative measures, second-line interventions, such as transanal irrigation or pelvic floor rehabilitation, can be initiated. A small proportion of patients will ultimately require an intervention such as sacral neuromodulation or permanent colostomy for refractory, major LARS symptoms.

Abstract
Background Defecation disorders after ileostomy reversal are among the most common complications for rectal cancer patients, and significantly diminish their quality of life. The aim of this study was to identify the risk factors associated with frequent defecation early after ileostomy reversal for rectal cancer patients. Methods We retrospectively collected the data of rectal cancer patients who underwent ileostomy reversal from January 2018 to December 2019 at the Sixth Affiliated Hospital of Sun Yat-sen University. We divided patients into two groups: a no frequent defecation group (≤7 times/day) and a frequent defecation group (>7 times/day). Results Of the 264 included patients, 59 patients (22.35%) had frequent defecation within 1 month after ileostomy closure and were defined as the frequent defecation group. There were no significant differences between the two groups in terms of gender, age, hypertension, and diabetes. Univariate and multivariate analyses showed that proctitis (P=0.04) and anastomotic stenosis (P=0.02) were independent risk factors for frequent defecation. Four factors, including proctitis, anastomotic stenosis, hypertension, and age were included to construct the nomogram. The consistency index of the nomogram was 0.949 and the area under the curve value was 0.623. Conclusions For rectal cancer patients, proctitis and anastomotic stenosis were correlated with frequent defecation within 1 month after ileostomy closure. Surgeons should pay attention to the rectal examination before ileostomy reversal surgery.

Abstract
BACKGROUND Improving survival rates in rectal cancer patients has generated a growing interest in functional outcomes after total mesorectal excision (TME). The well-established low anterior resection syndrome (LARS) score assesses postoperative anorectal impairment after TME. Our meta-analysis is the first to compare bowel function after open, laparoscopic, transanal, and robotic TME. METHODS All studies reporting functional outcomes after rectal cancer surgery (LARS score) were included, and were compared with a consecutive series of robotic TME (n = 48). RESULTS Thirty-two publications were identified, including 5 565 patients. Anorectal function recovered significantly better within one year after robotic TME (3.8 [95%CI -9.709-17.309]) versus laparoscopic TME (26.4 [95%CI 19.524-33.286]), p = 0.006), open TME (26.0 [95%CI 24.338-29.702], p = 0.002) and transanal TME (27.9 [95%CI 22.127-33.669], p = 0.003). CONCLUSIONS Robotic TME enables better recovery of anorectal function compared to other techniques. Further prospective, high-quality studies are needed to confirm the benefits of robotic surgery.

Abstract
BACKGROUND AND AIMS Low anterior resection syndrome is common after anterior resection for rectal cancer. Its severity can be tested with the low anterior resection syndrome score. We have translated the low anterior resection syndrome score to Finnish, and the aim of this study is to validate the translation. MATERIALS AND METHODS The translated Finnish low anterior resection syndrome score and European Organisation for Research and Treatment of Cancer quality-of-life questionnaire-C30 and QLQ-CR29 questionnaires were sent to 159 surviving patients operated with anterior resection for rectal adenocarcinoma between 2007 and 2014 in a tertiary referral center. Psychometric properties of the translation were evaluated in comparison to quality-of-life scales and in different risk factor groups. RESULTS In the study, 104 (65%) patients returned the questionnaires. Of these, 56 (54%) had major low anterior resection syndrome, 26 (25%) had minor low anterior resection syndrome, and 22 (21%) had no low anterior resection syndrome. Patients with major low anterior resection syndrome had a significantly lower quality of life and more defecatory symptoms as assessed with the European Organisation for Research and Treatment of Cancer questionnaires compared with those with no low anterior resection syndrome. Patients operated with total mesorectal excision had significantly higher low anterior resection syndrome scores compared with those operated with partial mesorectal excision (median/interquartile range 32/15 and 29/11, respectively, p = 0.037). The test-retest validity of the translation was good with an intraclass correlation coefficient of 0.77 (95% confidence interval 0.51-0.90). CONCLUSIONS The Finnish low anterior resection syndrome score is a valid test in the assessment of postoperative bowel function and its impact on the quality of life. It can be implemented to use during regular follow-up visits of Finnish-speaking rectal cancer patients.

Abstract
The prevalence of postoperative low anterior resection syndrome (LARS) in patients with colorectal cancer is high, which seriously affects the quality of life after operation. The purpose of this meta-analysis is to systematically evaluate the related factors of LARS in patients with colorectal cancer and provide reference for clinicians when making reasoned decisions. A systematic electronic search of PubMed, Embase, The Cochrane Library, WANFANG and CNKI was performed from 2012 to Dec 2020. We analyzed the risk factors of LARS by extracting baseline data and clinical results. The odds ratio (OR) was used to analyze binary variables. A total of 5102 patients were included in 21 literatures, of which the prevalence of LARS was 49.7% (2538/5102). Meta-analysis showed that there was no significant difference in the influence of age (P = 0.48) and sex (P = 0.68) on LARS, but low tumor height (P < 0.001), low anastomotic height (P < 0.001), radiotherapy and chemotherapy (P < 0.001) and postoperative anastomotic leakage (P < 0.001), disfunction stoma (P < 0.001) are high risk factors for the prevalence of LARS. Low tumor height, low anastomotic height, radiotherapy and chemotherapy, anastomotic leakage and disfunction stoma are risk factors for postoperative LARS in patients with colorectal cancer. Clinicians should pay attention to these indicators of patients to provide better clinical intervention for patients and improve their quality of life after operation.

Abstract
BACKGROUND Many patients after sphincter-preserving surgery experienced anorectal functional disturbances which were known as low anterior resection syndrome (LARS). Although many studies investigated LARS, there was inconsistency of their assessment tools and results. The aim of this systematic review was to elucidate the incidence and risk factors of LARS by a validated tool-LARS score. METHODS A systematic literature search in Pubmed, Embase, and Cochrane Library was conducted in April 2020. Studies investigating patients who were evaluated by LARS score 1 year after their sphincter-preserving surgery due to rectal cancer were included. Meta-analysis of incidence was conducted using the double arcsine method. Meta-analysis of each risk factor was conducted using a random effects model. RESULTS A total of 50 studies were included. The pooled incidence of major LARS was 44% (95% CI 40-48%; I2 = 88%; 36 studies). Long course neoadjuvant radiotherapy (OR 2.89, 95% CI 2.06-4.05; I2 = 47%; P < 0.01; 10 studies), total mesorectal excision (TME) (OR 2.13, 95% CI 1.49-3.04; I2 = 53%; P < 0.01; 7 studies), anastomotic leak (OR 1.98, 95% CI 1.34-2.93; I2 = 39%; P < 0.01; 9 studies), and diverting stoma (OR 1.89, 95% CI 1.58-2.27; I2 = 0%; P < 0.01; 13 studies) were associated with increased risk of major LARS. No significant difference was found in major LARS incidence between transanal TME and laparoscopic TME (OR 1.36, 95% CI 0.78-2.40; I2 = 19%; P = 0.28; 4 studies). Pouch reconstruction failed to lower the risk of major LARS in long term (OR 1.43, 95% CI 0.88-2.33; I2 = 70%; P = 0.29; 9 studies). CONCLUSION The incidence of major LARS after sphincter-preserving surgery is relatively high. Neoadjuvant radiotherapy, TME, anastomostic leak, and diverting stoma are major risk factors. No significant differences in postoperative anorectal functions were observed between transanal and laparoscopic TME. Pouch reconstruction was not found to be significantly beneficial to anorectal functions in long term.

Abstract
BACKGROUND Redo anastomosis can be considered in selected patients with persistent leakage, stenosis, or local recurrence. It is technically challenging, and little is known about the functional outcomes after this seldomly performed type of surgery. OBJECTIVE The aim of this study was to compare functional outcomes and the quality of life between redo anastomosis and primary successful anastomosis following total mesorectal excision for rectal cancer. DESIGN This study was designed as an international multicenter comparative cohort study. SETTINGS The study was conducted in 3 tertiary referral centers in the Netherlands, Belgium, and France. PATIENTS Patients undergoing redo anastomosis were compared with patients with a primary successful anastomosis after total mesorectal excision for rectal cancer. MAIN OUTCOME MEASURES Low anterior resection syndrome score, European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) C30, and EORTC QLQ-CR29 questionnaires were used to assess outcomes. RESULTS In total, 170 patients were included; 52 underwent redo anastomosis and 118 were controls. Major low anterior resection syndrome occurred in 73% after redo anastomosis compared with 68% following primary successful anastomosis (p = 0.52). The redo group had worse EORTC QLQ-CR29 mean scores for fecal incontinence (p = 0.03) and flatulence (p = 0.008). There were no differences in urinary (p = 0.48) or sexual dysfunction, either in men (p = 0.83) or in women (p = 0.76). Significantly worse scores in the redo group were found for global health (p = 0.002), role (p = 0.049) and social function (p = 0.006), body image (p = 0.03), and anxiety (p = 0.02). LIMITATIONS This study is limited by the possible response bias. CONCLUSIONS Redo anastomosis is associated with significantly worse quality of life compared with primary successful anastomosis. However, major low anterior resection syndrome was comparable between groups and should not be a reason to preclude restoration of bowel continuity in highly motivated patients.

Impact of a defunctioning ileostomy and time to stoma closure on bowel function after low anterior resection for rectal cancer: a systematic review and meta-analysis.

Abstract
BACKGROUND Impaired bowel function after low anterior resection (LAR) for rectal cancer is a frequent problem with a major impact on quality of life. The aim of this study was to assess the impact of a defunctioning ileostomy, and time to ileostomy closure on bowel function after LAR for rectal cancer. METHODS We performed a systematic review based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Comprehensive literature searches were conducted using PubMed, Embase and Cochrane databases for articles published from 1989 up to August 2019. Analysis was performed using Review Manager (version 5.3) using a random-effects model. RESULTS The search yielded 11 studies (1400 patients) that reported on functional outcome after LAR with at least 1 year follow-up, except for one study. Five scales were used: the Low Anterior Resection Syndrome (LARS) score, the Wexner score, the Memorial Sloan Kettering Cancer Centre Bowel Function Instrument, the Fecal Incontinence Quality of Life scale, and the Hallbook questionnaire. Based on seven studies, major LARS occurred more often in the ileostomy group (OR 2.84, 95% CI, 1.70-4.75, p < 0.0001: I2 = 60%, X2 = 0.02). Based on six studies, a longer time to stoma closure increased the risk of major LARS with a mean difference in time to closure of 2.39 months (95% CI, 1.28-3.51, p < 0.0001: I2 = 21%, X2 = 0.28) in the major vs. no LARS group. Other scoring systems could not be pooled, but presence of an ileostomy predicted poorer bowel function except with the Hallbook questionnaire. CONCLUSIONS The risk of developing major LARS seems higher with a defunctioning ileostomy. A prolonged time to ileostomy closure seems to reinforce the negative effect on bowel function; therefore, early reversal should be an important part of the patient pathway.

Abstract
Background/aim Sphincter-preserving surgery is one of the main goals in the treatment of rectal cancer because it improves the quality of life (QoL). However, some patients may experience disrupted symptoms called anterior or low anterior resection syndrome (LARS). This study was designed to evaluate the frequency and influencing factors of LARS in patients who underwent sigmoid or rectal resection. Materials and methods In this retrospective, clinical study, patients who underwent rectal or sigmoid resection and anastomosis due to any benign and malignant reasons were evaluated in terms of LARS between January 2010 and November 2019 at Medical Faculty Hospital of Mersin University. The frequency and severity of LARS were determined by using a standard scale. Furthermore, influencing factors including lesion localization, operation, the proximity of anastomosis to the anal verge, creation of stoma, chemotherapy, and radiotherapy application were investigated. Results Out of a total of 550 patients, 276 were included in this study. The major LARS incidence was found as 27.2%. Very low anterior resection (VLAR) (OR = 42.40 (95% CI [11.14–161.36], P < 0.0001), protective ileostomy (OR = 12.83 (95% CI [6.58–25.0], P < 0.0001), end colostomy (OR = 8.55 (95% CI [1.36–53.61], P = 0.022), receiving chemotherapy (OR = 3.08 (95% CI [1.71–5.53], P < 0.0001), and radiotherapy (OR = 2.51 (95% CI [1.38–4.57], P = 0.003) and the ROC analysis showed that creating an anastomosis placed at most 8.5 cm from the anal verge was found to be a major influencing factor on LARS (P < 0.05). Conclusions LARS may frequently occur in patients who have undergone rectal resection. In this study, the most important factors influencing LARS were found to be the proximity of anastomosis to the anal canal and creating a protective stoma. Receiving chemoradiotherapy also plays an important role in LARS.

Abstract
Despite advances in coloanal anastomosis techniques, satisfactory procedures completed without complications remain lacking. We investigated the effectiveness of our recently developed ‘Short stump and High anastomosis Pull-through’ (SHiP) procedure for delayed coloanal anastomosis without a stoma. In this retrospective study, we analysed functional outcomes, morbidity, and mortality rates and local recurrence of 37 patients treated using SHiP procedure, out of the 282 patients affected by rectal cancer treated in our institution between 2012 and 2020. The inclusion criterion was that the rectal cancer be located within 4 cm from the anal margin. One patient died of local and pulmonary recurrence after 6 years, one developed lung and liver metastases after 2 years, and one experienced local recurrence 2.5 years after surgery. No major leak, retraction, or ischaemia of the colonic stump occurred; the perioperative mortality rate was zero. Five patients (13.51%) had early complications. Stenosis of the anastomosis, which occurred in nine patients (24.3%), was the only long-term complication; only three (8.1%) were symptomatic and were treated with endoscopic dilation. The mean Wexner scores at 24 and 36 months were 8.3 and 8.1 points, respectively. At the 36-month check-up, six patients (24%) had major LARS, ten (40%) had minor LARS, and nine (36%) had no LARS. The functional results in terms of LARS were similar to those previously reported after immediate coloanal anastomosis with protective stoma. The SHiP procedure resulted in a drastic reduction in major complications, and none of the patients had a stoma.

Abstract
BACKGROUND/OBJECTIVE Neoadjuvant radiotherapy plays a vital role in rectal cancer treatment, but impairs postoperative bowel function, leading to low anterior resection syndrome (LARS). Neoadjuvant chemotherapy alone might avoid the negative effect of radiotherapy on bowel function. This study aims to assess the impact of neoadjuvant chemotherapy on LARS and the development of LARS over the first 6 months after surgery. METHODS Rectal cancer patients were prospectively recruited during June 30, 2018 and December 24, 2019. Bowel function was assessed by the LARS score, which was taken at 1 month, 3 months, and 6 months after surgery via phone call interview. Patients were divided into two groups based on whether they received neoadjuvant chemotherapy (group A) or not (group B). RESULTS A total of 97 patients were included in the analysis. There was no significant difference between the LARS scores at 1 month, 3 months, and 6 months of both groups. The LARS score at 6 months showed a significant decrease from that of 1 month and 3 months in group B (P < 0.05, P < 0.01) and in all patients (P < 0.05, P = 0.001), and significant difference was found between the LARS scores in group A at the three timepoints (P < 0.05). No significant difference was found between the scores at 1 month and 3 months in both groups and in all patients. CONCLUSION Neoadjuvant chemotherapy alone did not have a negative impact on LARS. The bowel function after surgery started to show significant improvement at 6 months after surgery.

Abstract
To identify low anterior resection syndrome (LARS) patterns and their associations with risk factors and quality of life (QOL). This cross-sectional study analyzed patients who underwent restorative anterior resection for left-sided colorectal cancer at Seoul National University Hospital, Seoul, Republic of Korea. We administered LARS questionnaires to assess bowel dysfunction and quality of life between April 2017 and November 2019. LARS patterns were classified based on factor analyses. Variable effects on LARS patterns were estimated using logistic regression analysis. The risk factors and quality of life associated with dominant LARS patterns were analyzed. Data of 283 patients with a median follow-up duration of 24 months were analyzed. Major LARS was observed in 123 (43.3%) patients. Radiotherapy (odds ratio [OR]: 2.851, 95% confidence interval [95% CI]: 2.504–43.958, p = 0.002), low anastomosis (OR: 10.492, 95% CI: 2.504–43.958, p = 0.001), and complications (OR: 2.163, 95% CI: 1.100–4.255, p = 0.025) were independently associated with major LARS. LARS was classified into incontinence- or frequency-dominant types. Risk factors for incontinence-dominant LARS were radiotherapy and complications, whereas those for frequency-dominant LARS included low tumor location. Patients with incontinence-dominant patterns showed lower emotional function, whereas those with frequency-dominant patterns showed lower global health QOL, lower emotional, cognitive, and social functions, and higher incidence of pain and diarrhea. Frequency-dominant LARS had a greater negative effect on QOL than incontinence-dominant LARS. These patterns could be used for preoperative prediction and postoperative treatment of LARS.

Abstract
AIM Little is known about the pathophysiology of low anterior resection syndrome (LARS), and evidence concerning the management of patients diagnosed with this condition is scarce. The aim of the LARS Expert Advisory Panel was to develop practical guidance for healthcare professionals dealing with LARS. METHOD The 'Management guidelines for low anterior resection syndrome' (MANUEL) project was promoted by a team of eight experts in the assessment and management of patients with LARS. After a face-to-face meeting, a strategy was agreed to create a comprehensive, practical guide covering all aspects that were felt to be clinically relevant. Eight themes were decided upon and working groups established. Each working group generated a draft; these were collated by another collaborator into a manuscript, after a conference call. This was circulated among the collaborators, and it was revised following the comments received. A lay patient revised the manuscript, and contributed to a section containing a patient's perspective. The manuscript was again circulated and finalized. A final teleconference was held at the end of the project. RESULTS The guidance covers all aspects of LARS management, from pathophysiology, to assessment and management. Given the lack of sound evidence and the often poor quality of the studies, most of the recommendations and conclusions are based on the opinions of the experts. CONCLUSIONS The MANUEL project provides an up-to-date practical summary of the available evidence concerning LARS, with useful directions for healthcare professional and patients suffering from this debilitating condition.

Abstract
Background: There is a relative shortage of studies directly addressing the postoperative rectal cancer patients' evacuatory dysfunction, as estimated by the low anterior resection syndrome (LARS) score at repeated assessment time-points. The aim of the present study was to prospectively evaluate the incidence of LARS at predefined time intervals during the first 3 years after sphincter preserving rectal cancer surgery and to enlighten the effect of identified risk factors.Materials and methods: Seventy-eight patients, who remained alive and recurrence-free 2 years after (ultra-) low anterior resection were prospectively assessed at 6, 12, 18, 24, 30 and 36 months postoperatively, using the LARS score as bowel dysfunction outcome measure. All patients have completed the 2-year follow-up functional assessment, while 56 and 37 of them have been evaluated up to the 30th and the 36th postoperative month, respectively.Results: The proportion of patients with "major and minor" LARS significantly decreased during the first 3 evaluations (up to 18 months) (74% vs 62% vs 35%, p = 0.0001). The tumor distance from the anal verge and the neoadjuvant radiotherapy were identified as risk factors for high LARS score at 6 months (p < 0.03). The tumor distance remained as risk factor throughout the entire follow-up. All patients with high tumors were alleviated from symptoms reflecting "major" or "minor" LARS at 18 months. Most patients (90%) after radiotherapy showed a high LARS score in the first semester, but improved afterwards.Conclusion: Overall, the LARS score improves in the majority of patients after 18 months, with low tumor height and radiation adversely affecting them. Our results may be useful in more accurately define the postoperative "functional course" of rectal cancer patients and in aiding their consultation on expected functional outcome.

Abstract
INTRODUCTION Radical surgery after a total mesorectal excision (TME) for rectal cancer often results in a significant decrease in the patient's quality of life, due to functional problems such as bowel, urinary and sexual dysfunction. The effect of pelvic floor muscle training (PFMT) on these symptoms has been scarcely investigated. We hypothesise that the proportion of successful patients will be significantly higher in the intervention group, receiving 12 weeks of PFMT, compared with the control group without treatment. The primary outcome of this trial is the severity of bowel symptoms, measured through the Low Anterior Resection Syndrome questionnaire, 4 months after TME or stoma closure. Secondary outcomes are related to other bowel and urinary symptoms, sexual function, physical activity and quality of life. METHODS AND ANALYSIS This research protocol describes a multicentre single blind prospective, randomised controlled trial. Since January 2017, patients treated for rectal cancer (n=120) are recruited after TME in three Belgian centres. One month following surgery or, in case of a temporary ileostomy, 1 month after stoma closure, patients are randomly assigned to the intervention group (n=60) or to the control group (n=60). The assessments concern the preoperative period and 1, 4, 6, 12 and 24 months postoperatively. ETHICS AND DISSEMINATION The study will be conducted in accordance with the Declaration of Helsinki. Ethics approval was granted by the local Ethical Committee of the University Hospitals Leuven (s59761) and positive advice from the others centres has been obtained. Dissemination of the results will be accomplished via guidelines and (non-)scientific literature for professionals as well as organisation of patient symposia. TRIAL REGISTRATION NUMBER NTR6383.

Abstract
BACKGROUND Anterior resection (AR) may result in defecatory dysfunction and the cause is multifactorial. The aim was to explore if dysfunction could be related to the part of the colon used for anastomosis (sigmoid or descending) and to identify other possible risk factors for bowel dysfunction after AR. METHODS This is a retrospective study based on prospectively registered data from a regional registry at the surgical department in Västmanland 1996-2019. Bowel function was registered at 1 year after AR or after stoma reversal. In total, 470 stage I-III rectal cancer patients had AR whereof 412 were included in this study. RESULTS Clustering was seen in 57%, incontinence 29%, urgency 22%, and evacuatory dysfunction 16%. The part of the colon used for anastomosis, level of vascular tie, and gender were not significantly associated with defecatory dysfunction. The higher the anastomotic level, the lower the risk of incontinence (OR 0.75; CI 0.63-0.90; p < 0.001) and clustering (OR 0.78; CI 0.67-0.90; p < 0.001). Compared with patients without a loop-ileostomy, an increased risk of clustering (OR 1.89; 1.08-3.31; p = 0.03), incontinence (OR 2.48; 1.29-4.77; p < 0.01), and urgency (OR 4.61; CI 2.02-10.60; p < 0.001) was seen after loop-ileostomy closure. Preoperative radiotherapy had a negative impact on continence and clustering seen mainly in the unadjusted analysis. CONCLUSION The part of the colon used for anastomosis was not a significantly associated functional outcome after anterior resection. Low anastomotic level and having had a diverting ileostomy were independent risk factors associated with negative functional outcomes.

Retrospective study of the functional and oncological outcomes of conformal sphincter preservation operation in the treatment of very low rectal cancer. Tech Coloproctol 2020; 24:1025-1034. [PMID: 32361871 PMCID: PMC7522072 DOI: 10.1007/s10151-020-02229-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Accepted: 04/18/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Conformal sphincter preservation operation (CSPO) is a new surgical procedure for very low rectal cancers (within 4-5 cm from the anal verge). CSPO preserves more of the dentate line and distal rectal wall and also avoids injuring nerves in the intersphincteric space, resulting in satisfactory anal function after resection. The aim of this study was to analyze the short-term surgical results and long-term oncological and functional outcomes of CSPO. METHODS Consecutive patients with very low rectal cancer, who had CSPO between January 2011 and October 2018 at Changhai Hospital, Shanghai were included. Patient demographics, clinicopathological features, oncological outcomes and anal function were analyzed. RESULTS A total of 102 patients (67 men) with a mean age of 56.9 ± 10.8 years were included. The median distance of the tumor from the anal verge was 3 (IQR, 3-4) cm. Thirty-five patients received neoadjuvant chemoradiation (nCRT). The median distal resection margin (DRM) was 0.5 (IQR, 0.3-0.8) cm. One patient had a positive DRM. All circumferential margins were negative. There was no perioperative mortality. The postoperative complication rate was 19.6%. The median duration of follow-up was 28 (IQR, 12-45.5) months. The local recurrence rate was 2% and distant metastasis rate was 10.8%. The 3-year overall survival and disease-free survival rates were 100% and 83.9%, respectively. The mean Wexner incontinence and low anterior resection syndrome scores 12 months after ileostomy reversal were 5.9 ± 4.3, and 29.2 ± 6.9, respectively. CONCLUSIONS For patients with very low rectal cancers, fecal continence can be preserved with CSPO without compromising oncological results.

Abstract
PURPOSE OF REVIEW Low anterior resection syndrome is a highly prevalent condition that can develop after anal sphincter-sparing surgery for rectal cancer and impair quality of life. In this review, we summarize the major features and pathophysiology of this syndrome and discuss treatment approaches. RECENT FINDINGS Quality of life correlates significantly with severity of low anterior resection syndrome. Prompt assessment and initiation of therapy are essential to rehabilitating damaged mechanical and neural structures. Anorectal manometry demonstrates a global decrease in sphincteric function postoperatively, though in many patients, function does recover. Transanal irrigation, pelvic floor rehabilitation, and biofeedback are the mainstays of the treatment of major LARS. Definitive stoma can be considered in therapy refractory LARS > 2 years. The development of low anterior resection syndrome likely involves an interplay between mechanical and neural pathways. Clinically, patients present at varying levels of severity, and scoring systems are available to help assess patient symptoms and guide therapy. Treatment approaches range from conservative therapies to biofeedback and sacral nerve stimulation. Future randomized controlled trials aimed at risk stratification of patients and development of severity-based treatment algorithms are warranted.
