Functional outcomes and quality of life following open versus laparoscopic versus robot-assisted versus transanal total mesorectal excision in rectal cancer patients: a systematic review and meta-analysis. Surg Endosc 2024; 38:4431-4444. [PMID: 38898341 PMCID: PMC11289076 DOI: 10.1007/s00464-024-10934-4] [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: 03/28/2024] [Accepted: 05/17/2024] [Indexed: 06/21/2024]
Abstract
BACKGROUND The standard surgical treatment for rectal cancer is total mesorectal excision (TME), which may negatively affect patients' functional outcomes and quality of life (QoL). However, it is unclear how different TME techniques may impact patients' functional outcomes and QoL. This systematic review and meta-analysis evaluated functional outcomes of urinary, sexual, and fecal functioning as well as QoL after open, laparoscopic (L-TME), robot-assisted (R-TME), and transanal total mesorectal excision (TaTME). METHODS A systematic review and meta-analysis, based on the preferred reporting items for systematic reviews and meta-analysis statement, were conducted (PROSPERO: CRD42021240851). A literature review was performed (sources: PubMed, Medline, Embase, Scopus, Web of Science, and Cochrane Library databases; end-of-search date: September 1, 2023), and a quality assessment was performed using the Methodological index for non-randomized studies. A random-effects model was used to pool the data for the meta-analyses. RESULTS Nineteen studies were included, reporting on 2495 patients (88 open, 1171 L-TME, 995 R-TME, and 241 TaTME). Quantitative analyses comparing L-TME vs. R-TME showed no significant differences regarding urinary and sexual functioning, except for urinary function at three months post-surgery, which favoured R-TME (SMD [CI] -0 .15 [- 0.24 to - 0.06], p = 0.02; n = 401). Qualitative analyses identified most studies did not find significant differences in urinary, sexual, and fecal functioning and QoL between different techniques. CONCLUSIONS This systematic review and meta-analysis highlight a significant gap in the literature concerning the evaluation of functional outcomes and QoL after TME for rectal cancer treatment. This study emphasizes the need for high-quality, randomized-controlled, and prospective cohort studies evaluating these outcomes. Based on the limited available evidence, this systematic review and meta-analysis suggests no significant differences in patients' urinary, sexual, and fecal functioning and their QoL across various TME techniques.

Abstract
Introduction bowel dysfunction is the most common and disabling complication after anterior rectal resection (ARR) for cancer. We aimed to evaluate these complications in a cohort of Cameroonian patients, using the low anterior rectal syndrome (LARS) score. Methods we conducted a descriptive and analytical cross-sectional study, in two university hospitals of Yaoundé (Cameroon). Prospectively, we collected the records of all patients aged at least 18 years who had an ARR indicated for rectal cancer from January 2015 to March 2018. Alive patients among them were subsequently received in consultation at 1 and 3 years after surgery, for short and long-term assessment of their digestive function using the LARS score. Results during the study period, 28 patients underwent anterior rectal resection for rectal cancers. Short-term bowel function was evaluated in 23 patients. Their mean age was 48.42 ± 12.2 years and 14 were males. LARS was present in 10 of them (43.47%) and classified as "minor" in the majority of cases (n=6). The commonest bowel dysfunction at this term was splitting of stool (56.53%). Long-term digestive function was evaluated in 11 patients; LARS was found in 3 of them (27,27%) and classified as minor in all cases. Perfect continence was significantly improved (p=0.003) in the long term compared to the short-term status. Continence (p=0.049) and urgency (p=0.048) were better in patients who had a low colorectal anastomosis compared to those who had a colo supra-anal anastomosis. Conclusion after ARR for cancer, there is a high prevalence of LARS in the short term with an improvement in the long term.

Abstract
BACKGROUND Many patients experience anorectal dysfunction after rectal surgery, which is known as low anterior resection syndrome (LARS). Robotic systems have many technical advantages that may be suitable for functional preservation after low rectal resection. Thus, the study aimed to explore whether robotic surgery can reduce the incidence and severity of LARS. METHODS Patients undergoing minimally invasive sphincter-sparing surgery for low rectal cancer were enrolled between January 2015 and December 2020. The patients were divided into robotic or laparoscopic groups. The LARS survey was conducted at 6, 12 and 18 months postoperatively. Major LARS scores were analysed as the primary endpoint. In order to reduce confounding factors, one-to-two propensity score matches were used. RESULTS In total, 342 patients were enrolled in the study. At 18 months postoperatively, the incidence of LARS was 68.7% (235/342); minor LARS was identified in 112/342 patients (32.7%), and major LARS in 123/342 (36.0%). After matching, the robotic group included 74 patients, and the laparoscopic group included 148 patients. The incidence of major LARS in the robotic group was significantly lower than that in the laparoscopic group at 6, 12, and 18 months after surgery. In multivariate logistic regression analysis, tumour location, laparoscopic surgery, intersphincteric resection, neoadjuvant therapy, and anastomotic leakage were independent risk factors for major LARS after minimally invasive sphincter-sparing surgery for low rectal cancer. Furthermore, a major LARS prediction model was constructed. Results of model evaluation showed that the nomogram had good prediction accuracy and efficiency. CONCLUSIONS Patients with low rectal cancer may benefit from robotic surgery to reduce the incidence and severity of LARS. Our nomogram could aid surgeons in setting an individualized treatment program for low rectal cancer patients.

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

Abstract
PURPOSE Despite advances in neoadjuvant chemoradiotherapy and anal sphincter-preserving surgery for rectal cancer, bowel dysfunction is still unavoidable and negatively affects patients' quality of life. In this longitudinal study, we aimed to investigate the changes in bowel function with follow-up time and the effect of neoadjuvant chemoradiotherapy on bowel function following low anterior resection for rectal cancer. METHODS In this study, 171 patients with upper or middle rectal cancer who underwent low anterior resection between 2012 and 2018 were included. Bowel function was assessed longitudinally with Memorial Sloan Kettering Cancer Center Bowel Function Instrument and Wexner scores every 6 months after restoration of bowel continuity. Patients with at least 2 follow-up visits were included. RESULTS Overall, 100 patients received neoadjuvant chemoradiotherapy. Urgency, soilage, and fecal incontinence were noted within 24 months in the patients treated with neoadjuvant chemoradiotherapy. After 2 years of follow-up, significant bowel dysfunction and fecal incontinence were observed in the neoadjuvant chemoradiotherapy group. Low tumor level and neoadjuvant chemoradiotherapy were associated with delayed bowel dysfunction. CONCLUSION Neoadjuvant chemoradiotherapy in combination with low tumor level was significantly associated with delayed bowel dysfunction even after 2 years of follow-up. Therefore, careful selection and discussion with patients are paramount.

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
BACKGROUND Rectal cancer is commonly treated by chemoradiation therapy, followed by the low anterior resection anal sphincter-preserving surgery, with a temporary protecting ileostomy. After reversal of the stoma a condition known as low anterior resection syndrome (LARS) can occur characterized by a combination of symptoms such as urgent bowel movements, lack of control over bowel movements, and difficulty fully emptying the bowels. These symptoms have a significant negative impact on the quality of life for individuals who have survived the cancer. Currently, there is limited available data regarding the presence, risk factors, and effects of treatment for these symptoms during long-term follow-up. AIMS To evaluate long term outcomes of low anterior resection surgery and its correlation to baseline anorectal manometry (ARM) parameters and physiotherapy with anorectal biofeedback (BF) treatment. METHODS One hundred fifteen patients (74 males, age 63 ± 11) who underwent low anterior resection surgery for rectal cancer were included in the study. Following surgery, patients were managed by surgical and oncologic team, with more symptomatic LARS patients referred for further evaluation and treatment by gastroenterologists. At follow up, patients were contacted and offered participation in a long term follow up by answering symptom severity and quality of life (QOL) questionnaires. RESULTS 80 (70%) patients agreed to participate in the long term follow up study (median 4 years from stoma reversal, range 1-8). Mean time from surgery to stoma closure was 6 ± 4 months. At long term follow up, mean LARS score was 30 (SD 11), with 55 (69%) patients classified as major LARS (score > 30). Presence of major LARS was associated with longer time from surgery to stoma reversal (6.8 vs. 4.8 months; p = 0.03) and with adjuvant chemotherapy (38% vs. 8%; p = 0.01). Patients initially referred for ARM and BF were more likely to suffer from major LARS at long term follow up (64% vs. 16%, p < 0.001). In the subgroup of patients who underwent perioperative ARM (n = 36), higher maximal squeeze pressure, higher maximal incremental squeeze pressure and higher rectal pressure on push were all associated with better long-term outcomes of QOL parameters (p < 0.05 for all). 21(54%) of patients referred to ARM were treated with BF, but long term outcomes for these patients were not different from those who did not perform BF. CONCLUSIONS A significant number of patients continue to experience severe symptoms and a decline in their quality of life even 4 years after undergoing low anterior resection surgery. Prolonged time until stoma reversal and adjuvant chemotherapy emerged as the primary risk factors for a negative prognosis. It is important to note that referring patients for anorectal physiology testing alone tended to predict poorer long-term outcomes, indicating the presence of selection bias. However, certain measurable manometric parameters could potentially aid in identifying patients who are at a higher risk of experiencing unfavorable functional outcomes. There is a critical need to enhance current treatment options for this patient group.

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
OBJECTIVES Despite an increase in colorectal cancer (CRC) survival, less is known about CRC-specific long-term unmet supportive needs in Asian patients. This study aimed to examine the prevalence of long-term unmet needs and identify clinical and socio-demographic factors associated with increased unmet needs in Asian CRC survivors. DESIGN AND SETTING We conducted a cross-sectional study that assessed unmet needs using the Cancer Survivors' Unmet Needs scale. CRC survivors of at least two years after undergoing curative surgery were recruited from an outpatient clinic of a large public hospital in Singapore. RESULTS In total, 400 CRC survivors with a mean age of 64 and a median survival time post-surgery of 78 months participated in the study. Approximately half of patients (52%) reported at least one unmet need. Male gender (RR 1.19, p = 0.01), age greater than 65 years (RR 0.63, p < 0.0001), longer follow up of more than 5 years (RR 0.80, p = 0.009), presence of a permanent stoma (RR 1.78, p < 0.0001), prior radiotherapy in treatment course (RR 1.99, p < 0.0001), higher educational status (RR 1.30, p = 0.0002), currently employed (RR 0.84, p = 0.014), currently married (RR 0.84, p = 0.01) were significant predictors for increased unmet needs. CONCLUSION There is a high prevalence of unmet needs in long-term Asian CRC survivors, which underscores the importance of screening patients to allow for early detection of unmet needs. Our findings on sociodemographic and clinical predictors can inform the development of targeted interventions tailored to the need domains and improvement of survivorship programmes.

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
INTRODUCTION At our institute, we usually perform robot-assisted surgery for rectal cancer as minimally invasive surgery. It is necessary to recognize the tumor edge accurately when deciding where to place the distal cutting line of the rectum. In this article, with video presentation, we demonstrate the usefulness of intraoperative sonography (IOUS) for detecting the rectal tumor site in robotic surgery. This is the first report to discuss the IOUS image of rectal cancer. MATERIALS AND SURGICAL TECHNIQUE After mobilization of the rectum in robotic procedure, the rectum should be straightened. Drop the laparoscopic ultrasonography probe through the 12-mm assistant port and place it at the anterior wall of the rectum. By presenting operative and ultrasound findings simultaneously on a single monitor, the operator can recognize the tumor location accurately and decide on the cutting line. We report three cases in the supporting video presentation. DISCUSSION Rectal tumors can be detected by IOUS, and this modality is effective for determining the cutting line of the rectum. Real-time navigation by IOUS can be performed noninvasively and easily, so it is expected to be helpful in cases of robotic rectal cancer resection.

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.

Low Anterior Resection Syndrome (LARS) after Surgery for Rectal Cancer: An Inevitable Price to Pay for Survival, or a Preventable Complication? J Clin Med 2023; 12:5962.

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.

Wang Z, Shao SL, Liu L, Lu QY, Mu L, Qin JC. Machine learning model for prediction of low anterior resection syndrome following laparoscopic anterior resection of rectal cancer: A multicenter study. World J Gastroenterol 2023; 29:2979-2991. [PMID: 37274801 PMCID: PMC10237089 DOI: 10.3748/wjg.v29.i19.2979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 04/02/2023] [Accepted: 04/25/2023] [Indexed: 05/16/2023] Open
Abstract
BACKGROUND Low anterior resection syndrome (LARS) severely impairs patient postoperative quality of life, especially major LARS. However, there are few tools that can accurately predict major LARS in clinical practice. AIM To develop a machine learning model using preoperative and intraoperative factors for predicting major LARS following laparoscopic surgery of rectal cancer in Chinese populations. METHODS Clinical data and follow-up information of patients who received laparoscopic anterior resection for rectal cancer from two medical centers (one discovery cohort and one external validation cohort) were included in this retrospective study. For the discovery cohort, the machine learning prediction algorithms were developed and internally validated. In the external validation cohort, we evaluated the trained model using various performance metrics. Further, the clinical utility of the model was tested by decision curve analysis. RESULTS Overall, 1651 patients were included in the present study. Anastomotic height, neoadjuvant therapy, diverting stoma, body mass index, clinical stage, specimen length, tumor size, and age were the risk factors associated with major LARS. They were used to construct the machine learning model to predict major LARS. The trained random forest (RF) model performed with an area under the curve of 0.852 and a sensitivity of 0.795 (95%CI: 0.681-0.877), a specificity of 0.758 (95%CI: 0.671-0.828), and Brier score of 0.166 in the external validation set. Compared to the previous preoperative LARS score model, the current model exhibited superior predictive performance in predicting major LARS in our cohort (accuracy of 0.772 for the RF model vs 0.355 for the preoperative LARS score model). CONCLUSION We developed and validated a robust tool for predicting major LARS. This model could potentially be used in the clinic to identify patients with a high risk of developing major LARS and then improve the quality of life.

Abstract
Rectal cancer is one of the most common cancers. As much as 90% of patients with low rectal cancer complain of increased frequency of defecation, fecal incontinence, and evacuation problems after surgery, which is termed as low anterior resection syndrome (LARS). LARS detrimentally affects the quality of life for patients with rectal cancer. In this paper, we review the pathogenesis, risk factors, assessment tools, and treatment strategies for LARS.

Clin Oncol (R Coll Radiol) 2023; 35:e121-e134. [PMID: 35940977 DOI: 10.1016/j.clon.2022.07.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 06/12/2022] [Accepted: 07/04/2022] [Indexed: 01/18/2023]
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.

Management of Low Anterior Resection Syndrome (LARS) Following Resection for Rectal Cancer. Cancers (Basel) 2023; 15:cancers15030778. [PMID: 36765736 PMCID: PMC9913853 DOI: 10.3390/cancers15030778] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 01/21/2023] [Accepted: 01/22/2023] [Indexed: 02/03/2023] Open
Abstract
INTRODUCTION A total of 60-80% of patients undergoing rectal resection (mostly as a treatment for rectal cancer) suffer from a variety of partly severe functional problems despite preservation of the anal sphincter. These patients are summarized under the term low anterior resection syndrome (LARS). Preoperative radiotherapy, vascular dissection and surgical excision of the low rectum and mesorectum lead, alone or all together, to a significant impairment of colonic and (neo-) rectal motility. This results in a variety of symptoms (multiple defecation episodes, recurrent episodes of urge, clustering, incontinence, etc.) which are associated with severe impairment of quality of life (QOL). METHODS This narrative review summarizes the present state of knowledge regarding the pathophysiology of LARS as well as the evidence for the available treatment options to control the symptoms resulting from this condition. RESULTS A review of the literature (Medline, Pubmed) reveals a variety of treatment options available to control symptoms of LARS. Medical therapy, with or without dietary modification, shows only a modest effect. Pelvic floor rehabilitation consisting of muscle exercise techniques as well as biofeedback training has been associated with improvement in LARS scores and incontinence, albeit with limited scientific evidence. Transanal irrigation (TAI) has gained interest as a treatment modality for patients with LARS due to an increasing number of promising data from recently published studies. Despite this promising observation, open questions about still-unclear issues of TAI remain under debate. Neuromodulation has been applied in LARS only in a few studies with small numbers of patients and partly conflicting results. CONCLUSION LARS is a frequent problem after sphincter-preserving rectal surgery and leads to a marked impairment of QOL. Due to the large number of patients suffering from this condition, mandatory identification, as well as treatment of affected patients, must be considered during surgical as well as oncological follow-up. The use of a standardized treatment algorithm will lead to sufficient control of symptoms and a high probability of a marked improvement in QOL.

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.

Abstract
PURPOSE Sexual function is crucial for the quality of life and can be highly affected by preoperative therapy and surgery. The aim of this study was to identify potential risk factors for poor sexual function and quality of life. METHODS Female patients were asked to complete the Female Sexual Function Index (FSFI-6). Male patients were demanded to answer the International Index of Erectile Function (IIEF-5). RESULTS In total, 79 patients filled in the questionary, yielding a response rate of 41.57%. The proportion of women was represented by 32.91%, and the median age was 76.0 years (66.0-81.0). Sexual dysfunction appeared in 88.46% of female patients. Severe erectile dysfunction occurred in 52.83% of male patients. Univariate analysis showed female patients (OR: 0.17, 95%CI: 0.05-0.64, p = 0.01), older age (OR: 0.34, 95%CI 0.11-1.01, p = 0.05), tumor localization under 6cm from the anal verge (OR: 4.43, 95%CI: 1.44-13.67, p = 0.01) and extension of operation (APR and ISR) (OR: 0.13, 95%CI: 0.03-0.59, p = 0.01) as significant risk factors for poor outcome. Female patients (OR: 0.12, 95%CI: 0.03-0.62, p = 0.01) and tumors below 6 cm from the anal verge (OR: 4.64, 95%CI: 1.18-18.29, p = 0.03) were shown to be independent risk factors for sexual dysfunction after multimodal therapy in the multivariate analysis. Quality of life was only affected in the case of extensive surgery (p = 0.02). CONCLUSION Higher Age, female sex, distal tumors and extensive surgery (APR, ISR) are revealed risk factors for SD in this study. Quality of life was only affected in the case of APR or ISR.

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.

Estas operaciones están asociadas con el síndrome de resección anterior baja. Estudios recientes con limitaciones tanto metodológicas como de talla han estudiado la incidencia del síndrome de resección anterior bajo post-quirúrgico. Sin embargo, la evolución a largo plazo del síndrome de resección anterior baja y su acción sobre la calidad de vida relacionadas con la salud siguen sin estar claros.OBJETIVO:Evaluar el impacto de la resección anterior baja y el cierre de la ileostomía en la calidad de vida relacionadas con la salud a largo plazo y el síndrome post-resección anterior.AJUSTE:Se incluyeron todos los pacientes sometidos a una reseccción anterior baja de recto por cáncer asociada a una ileostomía de protección entre 2003 y 2016 en dos centros de gran volumen en el Reino Unido, se excluyeron los pacientes que presentaron fuga anastomótica.DISEÑO:Se revisaron los datos demográficos de todos los pacientes que presentaban el síndrome de resección anterior baja, se revisaron las puntuaciones de la calidad de vida relacionadas con el estado general de salud (EORTC-QLQ-C30) obtenidas a través de cuestionarios transversales enviados por correo.PACIENTES:478 pacientes fueron escogidos, 311 (65,1%) participaron del estudio en una media de 6,5 ± 0,2 años después de la resección anterior. Las tasas demográficas y de radio-quimioterapia neoadyuvante fueron similares (p > 0,05) entre los participantes y los no participantes.RESULTADOS:El porcentaje de pacientes que experimentaron síndrome de resección anterior baja mayor fue del 53,4% (166/311).PRINCIPALES MEDIDAS DE RESULTADO:Las puntuaciones funcionales en la calidad de vida relacionadas con estado general de salud mejoraron en los años posteriores al cierre de la ileostomía de protección, los cambios fueron significativos con relación al estreñimiento (p = 0,01), con relación a la actividad social (p = 0,03) y con las puntuaciones emocionales (p = 0,02), así como con la reducción de la prevalencia del síndrome de resección anterior baja mayor (p = 0,003).LIMITACIONES:La principal limitación del presente estudio mostró que los datos recopilados fueron transversales y no longitudinales, y que los pacientes no respondedores pueden haber tenido peores síntomas relacionados con el cáncer.CONCLUSIONES:Este primer estudio a gran escala, evalúa la función a largo plazo después de la resección anterior baja y el cierre de la ileostomía, demuestra una mejoría lineal en el síndrome de resección anterior baja de grado importante, más allá de los 6 años, asociado con la mejoría en las medidas clave de calidad de vida.

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
Objectives A large proportion of mid-low rectal cancer patients develop low anterior resection syndrome (LARS) after Sphincter-sparing surgery. This study aimed to investigate the effect of low anterior resection syndrome (LARS) on quality of life (QoL) in Chinese rectal cancer patients following sphincter-sparing surgery. Methods This was a comparative cross-sectional study. Between Jan 2019 to Jun 2020, 146 mid-low rectal cancer patients following sphincter-sparing surgery were enrolled. The low anterior resection syndrome (LARS) score was used to assess bowel dysfunction. According to the LARS score, patients were divided into three levels, no LARS (n = 34), minor LARS (n = 60), and major LARS (n = 52). The Functional Assessment of Cancer Therapy-Colorectal (FACT-C) was used to assess the QoL of the patients. Results The major LARS group had a significantly shorter level of tumor from the dentate line than the no LARS group. The total FACT-C score of 146 patients was 98.45 ± 17.83. The total FACT-C score and the score of each dimension (physical, emotional, functional dimensions, and colorectal cancer subscale) were significantly different between the minor LARS and major LARS groups, as well as between the no LARS and major LARS groups. Subgroups analyses of the FACT-C score stratified by each item in the LARS scales showed that except for flatus incontinence, patients with different frequencies of other symptoms (bowel frequency, liquid stool incontinence, liquid stool incontinence, stool clustering, urgent bowel movement) had a significantly different total score of FACT (all P < 0.01). Conclusions The LARS had a significant impact on the QoL in Chinese mid-low rectal cancer patients following sphincter-sparing surgery, especially in patients with major LARS.

Abstract
BACKGROUND Most patients who have undergone low anterior resection suffer from bowel dysfunction postoperatively. This condition is referred to as low anterior resection syndrome (LARS). The aim was to study defecatory patterns in LARS patients compared to a primary control group of fecal incontinence (FI) patients and normal subjects (NS) with the Fecobionics device. METHODS Fecobionics expulsion parameters were assessed in an interventional study design. The Fecobionics probe contained pressure sensors at the front, rear, and inside the bag. The bag was distended until urge sensation in rectum in 11 LARS patients (5F/6M, 63.2 ± 2.9 years), 11 FI subjects (7F/4M, 64.4 ± 2.5 years), and 11 NS (7F/4M, 63.6 ± 3.0 years). Defecation indices were computed from the Fecobionics data. All subjects had high-resolution anorectal manometry (ARM) and balloon expulsion test (BET) done. Symptoms were evaluated with LARS and Wexner scores. KEY RESULTS The LARS score in the LARS patients was 39.0 ± 0.6. The Wexner score in the LARS, FI, and NS groups was 14.2 ± 0.7, 10.1±1.0, and 0.0 ± 0.0 (p < 0.01). The resting anal pressure and squeeze pressure were lowest in LARS patients (p < 0.05). The urge volume was 11.8 ± 4.2, 59.6 ± 6.4, and 41.6 ± 6.4 ml in the LARS, FI, and NS groups, respectively (p < 0.001). The expulsion duration did not differ between groups. Defecation indices were lowest in the LARS patients (p < 0.05). ARM-BET confirmed the low urge volume in LARS patients whereas anal pressures did not differ between groups. CONCLUSIONS AND INFERENCES The LARS patients had low anal pressures and urge volume. Most Defecation Indices differed between the LARS group and the other groups.

Risk factors for Low Anterior Resection Syndrome (LARS) in patients undergoing laparoscopic surgery for rectal cancer. Surg Endosc 2022; 36:6059-6066. [PMID: 35137257 PMCID: PMC9283148 DOI: 10.1007/s00464-021-09002-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Accepted: 12/31/2021] [Indexed: 11/15/2022]
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
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
AbstractLow anterior resection syndrome (LARS) comprises a collection of symptoms affecting patients’ defecation after restorative surgery for rectal cancer. The aim of this work was to study the incidence and risk factors for LARS in China. Rectal cancer patients undergoing total mesorectal excision and colorectal anastomosis between May 2012 and January 2015 were identified from a single center. The patients completed the LARS score questionnaire through telephone. The clinical and pathological factors that may influence the occurrence of LARS were analyzed using univariate and multivariate logistic regression analysis. The influence of postoperative recovery time and pelvic dimensions on the occurrence of LARS was also analyzed. This study included 337 patients, at an average age of 61.03 SD11.32. The mean LARS score of the patients was 14.08 (range 0–41). A total of 126 patients (37.4%) developed LARS after surgery, including 63 (18.7%) severe cases. Compared with the scores within the initial 6 postoperative months, the LARS scores of the patients in 6~18 months after the surgery showed significant reductions (p < 0.01). In multivariate analysis, lower locations of anastomosis, pre-surgery radiotherapy, and shorter postoperative recovery time were significant predisposing factors for LARS. A subgroup analysis revealed that patients suffering from LARS over 18 months after surgery were found to have a significantly shorter interspinous distance than those without LARS (p < 0.05). LARS could improve over time after surgery. Lower anastomotic level and pre-surgery radiotherapy are risk factors for LARS.

Abstract
PURPOSE Patients with mid-to low-rectal cancer can have various dysfunctions of defecation after sphincter-saving resection. Defecation dysfunction can manifest as incontinence, urgency, or frequent bowel movements, and is called low anterior resection syndrome (LARS). This study aimed to examine LARS score and objective anorectal function indices in Chinese patients receiving sphincter-saving surgery for mid-to low-rectal cancer. METHOD This was a single-center cross-sectional study of patients undergoing sphincter-saving resection for low- or mid-rectal cancer and had restoration of trans-anal defecation for at least 1 month seen between January 2019 and June 2020. Patients completed a questionnaire regarding clinical characteristics, and Low Anterior Resection Syndrome (LARS) score and high-resolution anorectal manometry (HR-ARM) were used to assess defecation function. Multivariable analysis was used to identify variables significantly associated with defecation dysfunction. RESULTS 146 patients completed and returned the questionnaires. 25 healthy adults also participated as control group for the anorectal manometry. Approximately 76% of patients developed LARS after surgery, of which 35.6% had major LARS. In these patients, anorectal manometry indices including initial rectal sensory capacity and rectal fecal sensory capacity, were significantly lower than normal. Logistic regression analysis showed that preoperative chemo-radiotherapy and the tumor inferior margins being close to the dentate line, especially 2-5 cm, were independent risk factors for defecation dysfunction after surgery. CONCLUSIONS Defecation dysfunction is a frequent occurrence after sphincter-saving resection for mid- and low-rectal cancer. Preoperative chemo-radiotherapy and a shorter tumor inferior margins distance to the dentate line are independent factors for defecation dysfunction.

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
AIM The aim of this study was to investigate changes in bowel function and anorectal physiology (ARP) after anterior resection for colorectal cancer. METHOD Patients were recruited from November 2006 to September 2008. Cleveland Clinic Incontinence (CCI) scores and stool frequency were determined by patient questionnaires before surgery (t0 ) and at three (t3 ), six (t6 ), nine (t9 ) and 12 (t12 ) months after restoration of intestinal continuity. ARP measurements were recorded at T0 , T3 and T12 . Endoanal ultrasound was performed at T0 and T12 . RESULTS Eighty-nine patients were included. CCI score increased postoperatively then normalized, whereas stool frequency did not change. Patients who had neoadjuvant radiotherapy or a lower anastomosis had increased incontinence and stool frequency in the postoperative period, whereas those with defunctioning stomas or open surgery had increased stool frequency alone. Maximum resting pressure, volume at first urge and maximum rectal tolerance were reduced throughout the postoperative period. Radiotherapy, lower anastomosis and defunctioning stoma (but not operative approach) altered manometric parameters postoperatively. Maximum rectal tolerance correlated with incontinence and first urge with stool frequency. The length of the anterior internal anal sphincter decreased postoperatively. CONCLUSIONS Incontinence recovers in the first year after anterior resection. Radiotherapy, lower anastomosis, defunctioning stoma and open surgery have a negative influence on bowel function. ARP may be useful if bowel dysfunction persists beyond 12 months.

Seow-En I, Chok AY, Matchar DB, Yoon S, Chong DQ, Tan EKW. Long-term quality of life, sexual health and gastrointestinal function following colorectal cancer resection in an Asian cohort. Colorectal Dis 2021; 23:2348-2360. [PMID: 34097342 DOI: 10.1111/codi.15768] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 05/15/2021] [Accepted: 05/31/2021] [Indexed: 01/22/2023]
Abstract
AIM As populations age and cancer management improves, long-term survivorship and quality-of-life (QOL) outcomes are becoming equally important as oncological results. Data from Asian populations are scarce. We aimed to evaluate the sexual health, gastrointestinal function and QOL amongst colorectal cancer survivors in a tertiary referral centre in Singapore. METHOD Adults who had undergone elective curative surgery for non-metastatic colorectal cancer at least 2 years prior were included. Exclusion criteria were cognitive disease, serious postoperative complications or recurrent cancer. Participants were invited to complete the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires EORTC-QLQ-C30 and QLQ-CR29. Using multiple bivariate analysis, r scores were used to examine relationship trends between QOL domains and survivor sociodemographic and disease-specific characteristics. RESULTS From February 2017 to July 2019, 400 responses were recorded. Median age and follow-up duration were 64 years (range 32-90) and 78 months (interquartile range 49-113) respectively. Patients who had Stage III cancer had better overall QOL scores compared to Stage I/II. Rectal (vs. colon) cancer negatively influenced sexual health and gastrointestinal function, but did not appear to affect overall QOL. Amongst our cohort, 57% (n = 129) of men and 43% (n = 75) of women were sexually active. Markers of socioeconomic status, including employment, education and housing type, were found to significantly impact perception of various aspects of QOL. CONCLUSION Knowledge of factors which influence well-being can identify individuals who may benefit from tailored management strategies. Regular patient-doctor contact may play a role in building and maintaining positive perspectives of cancer survivors. Normative data should be obtained from local populations to facilitate future comparative research.

[PMID: 34419022 PMCID: PMC8379825 DOI: 10.1186/s12893-021-01313-0] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 06/29/2021] [Indexed: 02/08/2023] Open
Abstract
Background This study aims to compare colonic J-pouch and side-to-end anastomosis for rectal cancer in terms of surgical and bowel functional outcomes and quality of life (QoL). Methods A systematic literature search was performed in PubMed, Embase and Cochrane. The last search was performed on March 28, 2021. All randomized controlled trials comparing colonic J-pouch with side-to-end anastomosis for rectal cancer were enrolled. The main outcomes were bowel functional outcomes and QoL. The secondary outcomes were surgical outcomes including operative time, postoperative hospital stay, complications, and mortality. Results Nine articles incorporating 7 trials with a total of 696 patients (330 by J-pouch and 366 by side-to-end) were enrolled in this meta-analysis. The bowel functional outcomes were comparable between J-pouch and side-to-end groups in terms of stool frequency, urgency, and incomplete defecation at the short term (< 8 months), medium term (8–18 months), and long term (> 18 months) follow up evaluations. No difference was observed between groups with regards to QoL (SF-36: physical function, social function, and general health perception). Besides, surgical outcomes were also similar in two groups. Conclusion The currently limited evidence suggests that colonic J-pouch and side-to-end anastomosis are comparable in terms of bowel functional outcomes, QoL, and surgical outcomes. Surgeons may choose either of the two techniques for anastomosis. A large sample randomized controlled study comparing colonic J-pouch and side-to-end anastomosis for rectal cancer is warranted.

Distinctive features of small vessels on the mesorectal and parietal pelvic fascia as important landmarks in guiding precise inter-fascial dissection for low rectal cancer. Surg Endosc 2021; 36:1657-1665. [PMID: 34398285 DOI: 10.1007/s00464-021-08683-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Accepted: 08/07/2021] [Indexed: 02/05/2023]
Abstract
BACKGROUND The confinement of the pelvis and the complexity of pelvic fascial anatomy still pose difficulties in achieving good quality surgery for rectal cancer. We aimed to introduce small vessels on the mesorectal fascia and the parietal pelvic fascia as novel landmarks to aid in the identification of the inter-fascial dissection plane. Besides, the perioperative, survival, and functional outcomes of this surgical technique were reported. METHODS We first described that small vessels running on the mesorectal fascia and the parietal pelvic fascia showed distinctive features, which included (1) small vessels on the parietal fascia took the same orientation as the ureter or the sympathetic and parasympathetic nerve; (2) small vessels on the mesorectal fascia were coursing cranially and medially on the anterolateral aspect, and medially and caudally on the posterolateral aspect; (3) small vessels on the mesorectal fascia became invisible at the interface between the pelvic wall and the mesorectal fascia. These features could be applied in fascial identification and separation. Then, we reported the outcomes of low rectal cancer surgery with small vessels-guided technique. RESULTS From 2013 to 2016, a consecutive series of 310 patients with low rectal cancer underwent laparoscopic total mesorectal excision with small vessels-guided technique. The positive rate of circumferential resection margin was 3.2%, and complete mesorectal excision was achieved in 97.8% (303/310) patients. The 3-year overall survival, disease-free survival, and local recurrence rates were 89.4%, 79.7%, and 2.6%, respectively. The urinary function was considered normal in 96.8% of patients, with a moderate dysfunction in 3.2% of patients. Besides, 29.5% of male patients occurred sexual function injury. CONCLUSION Distinctive features of small vessels on the parietal pelvic fascia and the mesorectal fascia can serve as novel and additive landmarks in guiding precise inter-fascial dissection for low rectal cancer.

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
Many patients develop a variety of bowel dysfunction after sphincter preserving surgeries (SPS) for rectal cancer. The bowel dysfunction usually manifests in the form of low anterior resection syndrome (LARS), which has a negative impact on the patients’ quality of life. This study reviewed the LARS after SPS, its mechanism, risk factors, diagnosis, prevention, and treatment based on previously published studies. Adequate history taking, physical examination of the patients, using validated questionnaires and other diagnostic tools are important for assessment of LARS severity. Treatment of LARS should be tailored to each patient. Multimodal therapy is usually needed for patients with major LARS with acceptable results. The treatment includes conservative management in the form of medical, pelvic floor rehabilitation and transanal irrigation and invasive procedures including neuromodulation. If this treatment failed, fecal diversion may be needed. In conclusion, Initial meticulous dissection with preservation of nerves and creation of a neorectal reservoir during anastomosis and proper Kegel exercise of the anal sphincter can minimize the occurrence of LARS. Pre-treatment counseling is an essential step for patients who have risk factors for developing LARS.

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
BACKGROUND Bowel dysfunction after rectal cancer surgery is common, with some experiencing low anterior resection syndrome (LARS) is common after rectal cancer surgery. This study examined if transanal total mesorectal excision (TaTME) has a similar risk of LARS and altered quality of life (QoL) as patients who undergo low anterior resection (LAR). METHODS Patients who underwent TaTME or traditionally approached total mesorectal excision in a prospective colorectal cancer cohort study (2014-2019) were propensity score matched in a 1 : 1 ratio. LARS and QoL scores were assessed before and after surgery with a primary endpoint of major LARS at 12 months analysed for possible association between factors by logistic regression. RESULTS Of 61 TaTME and 317 LAR patients eligible, 55 from each group were propensity score matched. Higher LARS scores (30.6 versus 25.4, P = 0.010) and more major LARS (65 versus 42 per cent, P = 0.013; OR 2.64, 95 per cent c.i. 1.22 to 5.71) were reported after TaTME. Additionally, QoL score differences (body image, bowel frequency, and embarrassment) were worse in the TaTME group. CONCLUSIONS TaTME may be associated with more severe bowel dysfunction than traditional approaches to rectal cancer.

Abstract
Introduction — Low anterior resection syndrome (LARS) is a socially significant problem that impedes social adaptation and contributes to deterioration of life quality in patients.
The objective of this study was to search for the category of patients most prone to major LARS, as well as to identify the factors determining the severity of this syndrome manifestations.
Material and Methods — Systematic review and meta-analysis were performed according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The study selected publications that included the functional results of treatment of patients operated for rectal cancer. Functional impairments were assessed according to the international LARS Score. Statistical analysis was performed using the inverse-variance weighted average method (IVW) with calculation of the odds ratio logarithm and standard error of the mean.
Results — After a critical search and analysis of all literature sources, eight studies were found suitable for meta-analysis. In total, 1042 patients (796 men and 246 women) were included into statistical analysis, 409 of which (39.2%) had symptoms of major LARS. Chemotherapy was performed on 637 (62.5%) patients, while 568 subjects (55.5%) underwent radiation therapy, and anastomotic leaks were described in 89 (8.5%) people. According to the results of the meta-analysis, statistically significant factors were: preventative ostomy (OR=3.32, 95% CI 1.99-5.55, p<0.00001), chemotherapy (OR=1.98, 95% CI 1.23-3, 19, p=0.005), radiation therapy (OR=5.00, 95% CI 2.73-9.13, p <0.00001), anastomotic leaks (OR=2.93, 95% CI 2.30-3, 73, p<0.00001), anal verge distance from anastomosis site (OR=2.61, 95% CI 1.47-4.62, p=0.001).
Conclusion — The results of our meta-analysis allowed us identifying the group of rectal cancer patients most vulnerable to LARS. The risk of developing severe functional disorders is significantly higher in patients with low colorectal anastomosis, as well as in patients undergoing neoadjuvant radiation therapy.

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
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.

Prevalence of low anterior resection syndrome and impact on quality of life after rectal cancer surgery: population-based study. BJS Open 2020; 4:935-942. [PMID: 32530135 PMCID: PMC7528525 DOI: 10.1002/bjs5.50312] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Accepted: 05/12/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND The prevalence of major low anterior resection syndrome (LARS) after rectal cancer surgery varies from 17·8 to 56·0 per cent, but data from high-quality studies are sparse. The aim of this study was to determine the prevalence of LARS and its association with quality of life (QoL) in a large, well defined, population-based cohort. METHODS This was a population-based study that included all patients who had curative rectal cancer surgery with total or partial mesorectal excision in Stockholm County in Sweden between 2007 and 2013. Patients without a remaining stoma, free from cancer and alive in April 2017 were eligible for the study. The LARS score questionnaire, EORTC QLQ-C30 and Cleveland Clinic Florida Fecal Incontinence score were used as outcome measures. Adjusted mean scores (and differences) of EORTC QLQ-C30 for LARS groups were calculated using repeated measures ANCOVA regression models while adjusting for predefined confounders. RESULTS In total, 481 patients (82·6 per cent response rate) were included in the analysis. Mean follow-up time was 6·7 (range 3·4-11·0) years after surgery. The prevalence of LARS was 77·4 per cent (370 of 478 patients), with 53·1 per cent (254 of 478) experiencing major LARS. Patients with major LARS reported worse on all EORTC QLQ-C30 subscales (except for financial difficulties) than patients without LARS. A higher mean LARS score was associated with a greater impact on bowel-related QoL. CONCLUSION After anterior resection for rectal cancer, the majority of patients suffer from major LARS with a negative impact on QoL.

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.
