Effects on anorectal function of endoscopic submucosal dissection for rectal tumors involving the dentate line. Scand J Gastroenterol 2024:1-10. [PMID: 39145809 DOI: 10.1080/00365521.2024.2390011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 07/24/2024] [Accepted: 08/02/2024] [Indexed: 08/16/2024]
Abstract
OBJECTIVE Endoscopic submucosal dissection (ESD) is a specific procedure that uses an electrosurgical knife for en-bloc resectioning large tumors. However, no study has examined the effect of ESD on the defecation function of patients with rectal tumors. We aimed to investigate the potential effects caused by ESD by analyzing changes in the morphology and movement of the anorectum pre- and post-ESD. METHODS This prospective observational study included 11 patients with anorectal tumors who underwent ESD between April 2020 and February 2022. Pre-ESD assessments included anorectal manometry and defecography. Post-ESD assessments were conducted 2 months later, including anorectal manometry, defecography, and proctoscopy for ulcer and stenosis evaluation. RESULTS The median patient age was 73 years, including seven males and four females. Eight patients (73%) had a tumor in the lower rectum, and the extent of resection was less than 50% of the rectal lumen. Resection reached the dentate line in six cases (55%). In the patients with post-ESD mucosal defects involving the dentate line, the median of functional anal canal length significantly decreased from (3.4 cm pre-ESD to 2.8 cm post-ESD, p = 0.04). Defecography revealed one case with incomplete evacuation (<50%) and incontinence post-ESD. Interestingly, patients with pre-existing rectoceles noted resolution of lesions post-ESD. None of the patients reported daily constipation or fecal incontinence. CONCLUSIONS While rectal ESD is unlikely to cause significant real-world defecation difficulties, alterations in rectal and anal canal morphology and function may occur if the dentate line is involved in the resection range.

Effect of a Mobile Health-Based Remote Interaction Management Intervention on the Quality of Life and Self-Management Behavior of Patients With Low Anterior Resection Syndrome: Randomized Controlled Trial. J Med Internet Res 2024; 26:e53909. [PMID: 39137413 DOI: 10.2196/53909] [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: 10/24/2023] [Revised: 05/07/2024] [Accepted: 06/03/2024] [Indexed: 08/15/2024] Open
Abstract
BACKGROUND People who undergo sphincter-preserving surgery have high rates of anorectal functional disturbances, known as low anterior resection syndrome (LARS). LARS negatively affects patients' quality of life (QoL) and increases their need for self-management behaviors. Therefore, approaches to enhance self-management behavior and QoL are vital. OBJECTIVE This study aims to assess the effectiveness of a remote digital management intervention designed to enhance the QoL and self-management behavior of patients with LARS. METHODS From July 2022 to May 2023, we conducted a single-blinded randomized controlled trial and recruited 120 patients with LARS in a tertiary hospital in Hefei, China. All patients were randomly assigned to the intervention group (using the "e-bowel safety" applet and monthly motivational interviewing) or the control group (usual care and an information booklet). Our team provided a 3-month intervention and followed up with all patients for an additional 3 months. The primary outcome was patient QoL measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. The secondary outcomes were evaluated using the Bowel Symptoms Self-Management Behaviors Questionnaire, LARS score, and Perceived Social Support Scale. Data collection occurred at study enrollment, the end of the 3-month intervention, and the 3-month follow-up. Generalized estimating equations were used to analyze changes in all outcome variables. RESULTS In the end, 111 patients completed the study. In the intervention group, 5 patients withdrew; 4 patients withdrew in the control group. Patients in the intervention group had significantly larger improvements in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 total score (mean difference 11.51; 95% CI 10.68-12.35; Cohen d=1.73) and Bowel Symptoms Self-Management Behaviors Questionnaire total score (mean difference 8.80; 95% CI 8.28-9.32; Cohen d=1.94) than those in the control group. This improvement effect remained stable at 3-month follow-up (mean difference 14.47; 95% CI 13.65-15.30; Cohen d=1.58 and mean difference 8.85; 95% CI 8.25-9.42; Cohen d=2.23). The LARS score total score had significantly larger decreases after intervention (mean difference -3.28; 95% CI -4.03 to -2.54; Cohen d=-0.39) and at 3-month follow-up (mean difference -6.69; 95% CI -7.45 to -5.93; Cohen d=-0.69). The Perceived Social Support Scale total score had significantly larger improvements after intervention (mean difference 0.47; 95% CI 0.22-0.71; Cohen d=1.81). CONCLUSIONS Our preliminary findings suggest that the mobile health-based remote interaction management intervention significantly enhanced the self-management behaviors and QoL of patients with LARS, and the effect was sustained. Mobile health-based remote interventions become an effective method to improve health outcomes for many patients with LARS.

Garfinkle RC, McKenna NP. Low Anterior Resection Syndrome following Restorative Proctectomy for Rectal Cancer: Can the Surgeon Have Any Meaningful Impact? Cancers (Basel) 2024; 16:2307. [PMID: 39001370 PMCID: PMC11240414 DOI: 10.3390/cancers16132307] [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: 06/05/2024] [Revised: 06/20/2024] [Accepted: 06/22/2024] [Indexed: 07/16/2024] Open
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.

Hartmann's Procedure Versus Intersphincteric Abdominoperineal Excision in Patients with Rectal Cancer: Report from the Swedish Colorectal Cancer Registry (SCRCR). ANNALS OF SURGERY OPEN 2024; 5:e428. [PMID: 38911665 PMCID: PMC11191996 DOI: 10.1097/as9.0000000000000428] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 04/09/2024] [Indexed: 06/25/2024] Open
Abstract
Objective The primary outcome was to compare overall postoperative surgical complications within 30 days after Hartmann's procedure (HP) compared with intersphincteric abdominoperineal excision (iAPE). The secondary outcome was major surgical complications (Clavien-Dindo ≥ III). Background There is uncertainty regarding the optimal surgical method in patients with rectal cancer when an anastomosis is unsuitable. Methods Rectal cancer patients with a tumor height >5 cm, registered in the Swedish Colorectal Cancer Registry who received HP or iAPE electively in 2017-2020 were included, (HP, n = 696; iAPE, n = 314). Logistic regression analysis adjusting for body mass index, American Society of Anesthesiologists classification, sex, age, preoperative radiotherapy, tumor height, cancer stage, operating hospital, and type of operation was performed. Results Patients in the HP group were older and had higher American Society of Anesthesiologists scores. The mean operating time was less for HP (290 vs 377 min). Intraoperative bowel perforations were less frequent in the HP group, 3.6% versus 10.2%. Overall surgical complication rates were 20.3% after HP and 15.9% after iAPE (P = 0.118). Major surgical complications were 7.5% after HP and 5.7% and after iAPE (P = 0.351). Multiple regression analysis indicated a higher risk of overall surgical complications after HP (odds ratio: 1.63; 95% confidence interval = 1.09-2.45). Conclusions HP was associated with a higher risk of surgical complications compared with iAPE. In patients unfit for anastomosis, iAPE may be preferable. However, the lack of statistical power regarding major surgical complications, prolonged operating time, increased risk of bowel perforation, and lack of long-term outcomes, raises uncertainty regarding recommending intersphincteric abdominoperineal excision as the preferred surgical approach.

Abstract
Background After anterior resection (AR), one of the most debilitating complications is low anterior resection syndrome (LARS) seen in about 64% of patients. The severity of the LARS score was significantly correlated with neoadjuvant treatment, the extent of rectal surgery, complication by the anastomotic leak, female gender, and age < 64 years. In this study, we analyzed the impact of various clinical factors on LARS and also the various domains of quality of life (QoL). Purpose To assess the incidence of LARS in patients undergoing sphincter-sparing surgery for rectal cancer after the patient starts long-term defecating per anus, change in the QoL, and relation to LARS and factors affecting it. Methods One year before, 72 patients who had undergone AR in the Regional Cancer Centre were interviewed by a trained interviewer and data was collected from the file. The questionnaires used were the Wexner Incontinence score, LARS Malayalam Questionnaire, and European Organisation For Research and Treatment of Cancer (EORTC) QLQ C30 Malayalam translations. Statistical measures The LARS score was used to categorize patients into three grades. The scores were compared with clinical and social factors using the χ2 test for association. Continuous variables were compared by the Spearman Rho test. Results Details of patients were studied (male: 55.6% (40) and female: 44.4% (32)). Fifty patients underwent low anterior resection (LAR). The mean LARS score was 25.61, with 47.2% of patients having severe LARS score. The mean Wexner score was 6.84. The relation with type of surgery, approach (laparoscopic vs open), or type of neoadjuvant therapy was not found to be significant. A higher LARS score did not impact overall QoL as assessed by FACT-C. Insomnia and diarrhea symptoms scores were significantly worsened. The pain score was worse for those undergoing stapler anastomosis. Wexner's score was worse for those who had received adjuvant chemotherapy. Role functioning score was better for AR compared to low anterior resection (LAR). Only distance from the anal verge was found to be a significant cause of LARS and was negatively correlated. Discussion LARS of severe degrees were seen in most patients. No modifiable risk factors were significantly found to affect the chance of LARS. However, LARS did not have a significant impact on QoL, neither did the type of surgery. So sphincter preservation can be offered to the patients, but all patients undergoing LAR should be counseled well about the risk of LARS before surgery.

Abstract
PURPOSE Anastomotic leakage after anterior resection for rectal cancer induces bowel dysfunction, but the influence on urinary and sexual function is largely unknown. This cross-sectional cohort study evaluated long-term effect of anastomotic leakage on urinary and sexual function in male patients. METHODS Patients operated with anterior resection for rectal cancer in 15 Swedish hospitals 2007-2013 were identified. Anastomotic leakage and other clinical variables were retrieved from the Swedish Colorectal Cancer Registry and medical records. Urinary and sexual dysfunction were evaluated at 4 to 11 years after surgery using the International Prostate Symptom Score, International Index of Erectile Function, and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire CR29. The effect of anastomotic leakage on average scores of urinary and sexual dysfunction was evaluated as a primary outcome, and the single items permanent urinary catheter and sexual inactivity as secondary outcomes. The association of anastomotic leakage and functional outcomes was analyzed using regression models with adjustment for confounders. RESULTS After a median follow-up of 84 months (interquartile range: 67-110), 379 out of 864 eligible men were included. Fifty-nine (16%) patients had anastomotic leakage. Urinary incontinence was more common in the leakage group, with an adjusted mean score difference measured by EORTC QLQ ColoRectal-29 of 8.69 (95% confidence interval: 0.72-16.67). The higher risks of urinary frequency, permanent urinary catheter, and sexual inactivity did not reach significance. CONCLUSION Anastomotic leakage after anterior resection had a minor negative impact on urinary and sexual function in men.

Abstract
OBJECTIVES This study aimed to investigate the impact of bowel dysfunction and lower urinary tract symptoms on the quality of patients with rectal cancer who underwent sphincter-preserving surgery. METHODS This cross-sectional study included patients who were followed up after sphincter-preserving surgery in Korea. Data were collected from May 2022 to February 2023. The participants (n = 110) responded to self-reported questionnaires assessing the Low Anterior Resection Syndrome (LARS) score, International Prostate Symptom Score (IPSS), European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-C29 questionnaires. RESULTS Among the participants, 66.4% had major low anterior resection syndrome, and 39.1% had moderate-to-severe lower urinary tract symptoms. Patients with higher severity of low anterior resection syndrome and lower urinary tract symptoms had a lower quality of life. The IPSS, performance status, duration since the end of the surgery, comorbidities, LARS scores, and tumor location on the anal verge negatively affected the quality of life. CONCLUSION Patients with more severe bowel dysfunction or lower urinary tract symptoms have a poorer quality of life. Nurses should be made aware of the factors that can reduce the quality of life of patients who have undergone sphincter-preserving surgery. Accordingly, they should plan to address the various nursing problems.

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
BACKGROUND Trans-anal total mesorectal excision (Ta-TME) is a novel approach for the resection of rectal cancer. Low anterior resection syndrome (LARS) is a frequent functional disorder that might follow restorative proctectomy. Data regarding bowel function after Ta-TME are scarce. The aim of this study was to evaluate the incidence and risk factors for the development of LARS following Ta-TME. METHODS A prospectively maintained database of all patients who underwent Ta-TME for rectal cancer at our institution was reviewed. All patients who were operated on from January 2018 to December 2021 were evaluated. The LARS score questionnaire was used via telephone interviews. Incidence, severity and risk factors for LARS were evaluated. RESULTS Eighty-five patients underwent Ta-TME for rectal cancer between January 2018 and December 2021. Thirty-five patients were excluded due to ostomy status, death, local disease recurrence, ileal pouch or lack of compliance. Fifty patients were included in the analysis. LARS was diagnosed in 76% of patients. Anastomosis distance from dentate line was identified as a risk factor for LARS via multivariate analysis (p = 0.042). Neo-adjuvant therapy, hand sewn anastomosis and anastomotic leak did not increase the risk of LARS. CONCLUSION LARS is a frequent condition following ta-TME, as it is used for other approaches to low anterior resection. Anastomosis distance from dentate line is an independent risk factor for LARS. In this study neo-adjuvant therapy, hand sewn anastomosis and anastomotic leak did not increase the risk of LARS. Further studies with longer follow-up times are required to better understand the functional outcomes following Ta-TME.

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
Local and metastatic recurrence are primary concerns following the treatment of locally advanced rectal cancer (LARC). Chemoradiation (CRT) can reduce the local recurrence rates and has subsequently moved to the neoadjuvant setting from the adjuvant setting. Pathological complete response (pCR) rates have also been noted to be greater in patients treated with neoadjuvant CRT prior to surgery. The standard approach to treating LARC would often involve CRT followed by surgery and optional adjuvant chemotherapy and remained the treatment paradigm for almost two decades. However, patients were often unable to complete adjuvant chemotherapy due to a decreased tolerance of chemotherapy following surgery, which led to upfront treatment with both CRT and chemotherapy, and total neoadjuvant therapy, or TNT, was created. The efficacy outcomes of local recurrence, disease-free survival, and pCR have improved in patients receiving TNT compared to the standard approach. Additionally, more recent data suggest a possible improvement in overall survival as well. Patients with a complete clinical response following TNT have the opportunity for watch-and-wait surveillance, allowing some patients to undergo organ preservation. Here, we discuss the clinical trials and studies that led to the adoption of TNT as the standard of care for LARC, with the possibility of watch-and-wait surveillance for patients achieving complete responses. We also review the possibility of overtreating some patients with LARC.

Abstract
OBJECTIVE Low anterior resection syndrome (LARS) is one of the most common functional impairments after rectal cancer surgery with a high impact on quality of life. The Pre-Operative LARS score (POLARS) nomogram and its online tool has been developed to predict the degree of postoperative LARS. The aim of this study was to analyse how accurately the POLARS score could predict LARS scores when compared with actual patient-reported LARS (PR-LARS) scores in a population-based Swedish cohort. DESIGN This retrospective cohort study included patients who underwent curative rectal cancer surgery between 2007 and 2013 in Stockholm County and were identified using the Swedish Colorectal Cancer Registry (SCRCR). Information regarding preoperative risk factors, patient and treatment characteristics, and presence of LARS postoperatively were collected from patient charts, SCRCR and patient questionnaires. The POLARS model formula was used to predict LARS scores, which then were compared with the actual PR-LARS scores. Individual LARS score differences between the two estimates were shown with a modified Bland-Altman plot of difference. RESULTS The cohort included 477 patients, of whom 359 (75%) of patients were categorised as having no/minor LARS based on the POLARS score. The correctly identified patients by the POLARS score were 80/255 (31%) in the major LARS group and 184/222 (83%) no/minor LARS group. The sensitivity was 31% for major LARS and the positive predictive value was 68%. CONCLUSION The POLARS score has a low sensitivity for major LARS in this Swedish cohort. Other methods to predict the risk of LARS need to be developed.

Abstract
PURPOSE In patients with chemotherapy, there is no consensus on the timing of ileostomy closure. Ileostomy reversal could improve the quality of life and minimise the long-term adverse events of delayed closure. In this study, we evaluated the impact of chemotherapy on ileostomy closure and searched for the predictive factors for complications. METHODS We retrospectively analysed 212 patients with rectal cancer who underwent ileostomy closure surgery during and without chemotherapy and were consecutively enrolled between 2010 and 2016. As a result of the heterogeneity of the two groups, propensity score matching (PSM) was performed with a 1:1 PSM cohort. RESULTS A total of 162 patients were included in the analysis. The overall stoma closure-related complications (12.4% vs. 11.1%, p = 1.00) and major complications (2.5% vs. 6.2%, p = 0.44) were not significantly different between the two groups. Multivariate analysis demonstrated that chronic kidney disease and bevacizumab use are risk factors for major complications. CONCLUSION Patients with oral or intravenous chemotherapy can safely have ileostomy closure with an adequate time delay from chemotherapy. When patients use bevacizumab, major complications related to ileostomy closure should still be cautioned.

Eur J Oncol Nurs 2023; 67:102406.

Abstract
PURPOSE Currently cancer survivorship often leaves the needs of patients unidentified and unmet. The study aims to establish the views of experts on managing bowel symptoms following rectal cancer surgery. METHOD People living with bowel symptoms as well as clinicians with expertise in rectal cancer and subsequent bowel changes were invited to participate in online focus groups. Focus groups were recorded, transcribed verbatim and analysed using a modified framework analysis. Results were presented narratively with interpretations and quotations. RESULTS Fourteen patients following rectal cancer treatment attended one of two focus groups. Sixteen clinicians attended one of four groups. Participants described their opinions about bowel symptom management. Three themes were described by both patients and clinicians: expectations of bodily changes, supported self-repair and knowledgeable self-repair. Data from participants frequently concurred; all recognised clinicians needed to support and empower patients to independently manage their cancer consequences. CONCLUSION Well-managed expectations enable patients to set realistic goals and make plans. Clinicians need to support patients to understand potential bowel changes that might occur after rectal cancer surgery, providing support, information and signposting to other relevant information and colleagues. Effective communication through avoidance of jargon and rapport building as well as providing a point of contact help prevent patients feeling alone with their symptoms. Education is needed by both clinicians and patients to ensure consistent and useful advice is provided and understood. A recommendation from the focus groups is to create opportunities for patients to access information with clinician support and signposting.

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
OBJECTIVES Bowel dysfunction is frequently reported in patients with ovarian carcinoma (OC). Our aim was to evaluate the incidence of low anterior resection syndrome (LARS) like symptoms in patients with primary OC and its impact on quality of life (QoL). METHODS A prospective longitudinal observational cohort study was performed, including patients with newly diagnosed OC treated by primary or interval surgery with residual tumor <1 cm, from 2018 until 2021. Patients with a stoma or recurrence of disease were excluded. Intestinal dysfunction was assessed using the validated LARS score questionnaire pre- and postoperatively. There are 3 subgroups based on the results: no, minor, or major LARS. The impact on QoL was evaluated by an additional question to demonstrate the severity of patient's life impairment. RESULTS The questionnaire was answered by 78 patients pre- and post-operatively. LARS like symptoms were reported preoperatively in 34.6% (24.4% minor/10.2% major) and significantly increased postoperatively to 47.4% (28.2% minor/19.2% major; p = 0.011). Moderate to severe impairment of QoL correlated with LARS scores pre- (80%) and post-operatively (90%). Patients with two bowel anastomoses (mean score 18.6 pre- and 24.9 post-operatively, p = 0.041) showed a significant increase of the questionnaire score. CONCLUSIONS Major LARS like symptoms appear in 10% of OC patients preoperatively and significantly increase to almost two-fold postoperatively. Multiple bowel anastomoses had a significant risk for higher postoperative LARS score. QoL impairment correlates linearly with LARS positive scoring, independent on the timing of the complaints.

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
Background and Objectives: Full-thickness trans anal local excision for tumors with favorable response following neoadjuvant therapy for locally advanced rectal cancer (LARC) is a common strategy for organ preservation, but it could be associated with a high rate of postoperative complications. We describe the incidence and pattern of submucosal involvement in surgical specimens following neoadjuvant therapy for LARC and whether limiting local excision of the residual tumor bed to only mucosal/submucosal layers of the rectal wall is sufficient for accurately predicting the ypT status of residual cancer, providing a pathological rationale to replace full-thickness local excision by endoscopic submucosal resection. Materials and Methods: This was a single-institution retrospective study conducted at a teaching community hospital. We reviewed clinical and pathological findings with slides of 82 patients diagnosed with LARC treated at our center between 2006 and 2020. Eligibility criteria mirrored our current organ preservation trials. Results: No tumor was found in surgical specimens in 28 cases (34%). Additionally, 4, 22, 27, and 1 cases were staged as ypT1, ypT2, ypT3, and ypT4, respectively. Residual malignant cells were found in the submucosal layer in 98% of cases with ypT+ stage, with 'skip lesions' in only 2% of cases. Conclusions: A very high incidence of submucosal involvement is noticed in residual tumors after neoadjuvant therapy, providing pathological rationale to study the role of endoscopic submucosal resection as a restaging tool for tumors with favorable response after neoadjuvant therapy when organ preservation strategy is pursued. This study was limited by its retrospective design and relatively small number of patients.

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.

Buzatti KC, Petroianu A, Laurberg S, Silva RG, Rodrigues BD, Christensen P, Lacerda-Filho A, Juul T. Validation of low anterior resection syndrome score in Brazil with Portuguese. Ann Coloproctol 2023; 39:402-409. [PMID: 35569837 PMCID: PMC10626332 DOI: 10.3393/ac.2022.00136.0019] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 04/04/2022] [Accepted: 04/04/2022] [Indexed: 10/18/2022] Open
Abstract
PURPOSE This study was performed to investigate the convergent validity, discriminative validity, and reliability of the Brazilian version of the low anterior resection syndrome (LARS) score in a population with low educational and socioeconomic levels. METHODS The LARS score was translated into the Portuguese language by forward- and back-translation procedures. In total, 127 patients from a public hospital in Brazil completed the questionnaires. The convergent validity was tested by comparing the LARS score with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core Module 30 (QLQ-C30) and with patients' self-reported quality of life. For the discriminative validity, we tested the ability of the score to differentiate among subgroups of patients regarding neoadjuvant radiotherapy, type of surgery, and tumor distance from the anal verge. The test-retest reliability was investigated in a subgroup of 36 patients who responded to the survey twice in 2 weeks. RESULTS The LARS score demonstrated a strong correlation with 5 of 6 items from the EORTC QLQ-C30 (P<0.05) and good concordance with patients' self-reported quality of life (95.3%), confirming the convergent validity. The score was able to discriminate between subgroups of patients with different clinical characteristics related to LARS (P<0.001). The agreement between the test and retest showed that 86.1% of the patients remained in the same LARS category, and there was no significant difference between the LARS score numerical values (P=0.80), indicating good reliability overall. CONCLUSION The Brazilian version of the LARS score is a valid and reliable instrument to assess postoperative bowel function in a population with low educational and socioeconomic levels.

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.

Artificial Intelligence for context-aware surgical guidance in complex robot-assisted oncological procedures: An exploratory feasibility study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023:106996. [PMID: 37591704 DOI: 10.1016/j.ejso.2023.106996] [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: 03/13/2023] [Revised: 06/20/2023] [Accepted: 07/26/2023] [Indexed: 08/19/2023]
Abstract
INTRODUCTION Complex oncological procedures pose various surgical challenges including dissection in distinct tissue planes and preservation of vulnerable anatomical structures throughout different surgical phases. In rectal surgery, violation of dissection planes increases the risk of local recurrence and autonomous nerve damage resulting in incontinence and sexual dysfunction. This work explores the feasibility of phase recognition and target structure segmentation in robot-assisted rectal resection (RARR) using machine learning. MATERIALS AND METHODS A total of 57 RARR were recorded and subsets of these were annotated with respect to surgical phases and exact locations of target structures (anatomical structures, tissue types, static structures, and dissection areas). For surgical phase recognition, three machine learning models were trained: LSTM, MSTCN, and Trans-SVNet. Based on pixel-wise annotations of target structures in 9037 images, individual segmentation models based on DeepLabv3 were trained. Model performance was evaluated using F1 score, Intersection-over-Union (IoU), accuracy, precision, recall, and specificity. RESULTS The best results for phase recognition were achieved with the MSTCN model (F1 score: 0.82 ± 0.01, accuracy: 0.84 ± 0.03). Mean IoUs for target structure segmentation ranged from 0.14 ± 0.22 to 0.80 ± 0.14 for organs and tissue types and from 0.11 ± 0.11 to 0.44 ± 0.30 for dissection areas. Image quality, distorting factors (i.e. blood, smoke), and technical challenges (i.e. lack of depth perception) considerably impacted segmentation performance. CONCLUSION Machine learning-based phase recognition and segmentation of selected target structures are feasible in RARR. In the future, such functionalities could be integrated into a context-aware surgical guidance system for rectal surgery.

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.

Abstract
PURPOSE We aimed to estimate the effect of a 12-week web-based dietary intervention with text messages on quality of life (QoL) among colorectal cancer (CRC) survivors. METHODS Between 2017 and 2018, 50 CRC survivors were randomized (1:1) to receive a 12-week web-based dietary intervention with daily text messages or wait-list control. Health-related QoL was assessed using the European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) and colorectal quality of life module (QLQ-CR29) at baseline, 12, and 24 weeks. Within- and between-group mean changes in health-related QoL with 95% confidence intervals (CI) were calculated for both arms. RESULTS Compared to the controls, participants receiving the intervention had an improvement in emotional functioning (mean change: 14.3; 95% CI: 3.0, 25.6) at 12 weeks and social functioning (mean change: 13.8; 95% CI: 2.1, 25.5) at 24 weeks. A decrease of fatigue from baseline was also observed in the intervention arm (mean change: - 9.1; 95% CI: - 17.1, - 1.1) at 24 weeks. No other changes in QoL scores were associated with the intervention. CONCLUSION CRC survivors randomized to receive a web-based dietary intervention with text messages experienced higher emotional and social functioning. Further study with a larger population may be warranted. TRIAL REGISTRATION clinicaltrials.gov, NCT02965521. Registered 16 November 2016, https://clinicaltrials.gov/ct2/keydates/NCT02965521.

Clin Oncol (R Coll Radiol) 2023; 35:e121-e134. [PMID: 35940977 DOI: 10.1016/j.clon.2022.07.003] [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: 01/15/2022] [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.

Xia F, Zou Y, Zhang Q, Wu J, Sun Z. A novel nomogram to predict low anterior resection syndrome (LARS) after ileostomy reversal for rectal cancer patients. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:452-460. [PMID: 37406079 DOI: 10.1016/j.ejso.2022.10.015] [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: 07/22/2022] [Revised: 09/26/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND AND AIM Low anterior resection syndrome (LARS) in patients undergoing low or ultra-low anterior resection (LAR) is a common problem and significantly impacts the quality of life. Patients with an ileostomy after LAR are more likely to develop LARS. However, there hasn't been a model predicting LARS occurrence in these patients. This study aims to construct a nomogram to predict the probability of LARS occurrence in patients with temporary ileostomy and guide preventive strategies before reversal. METHODS 168 patients undergoing LAR with ileostomy from one center were enrolled as the training cohort, and 134 patients of the same inclusion criteria from another center were enrolled as the validation cohort. The training cohort was screened for risk factors for major LARS using univariate and multivariate logistic regression. The nomogram was constructed using the filtered variables, the ROC curve was used to describe the model's discrimination, and the calibration was used to describe the accuracy. RESULTS The optimal cut-off value for stoma closure time was 128 days. Three risk factors were identified using logistic regression analysis: preoperative radiotherapy (OR = 3.038, [95%CI 1.75-5.015], P = 0.005), stoma closure time (OR = 2.298, [95%CI 1.088-4.858], P = 0.029) and pN stage (OR = 1.739, [95%CI 1.235-3.980], P = 0.001). A nomogram was constructed based on these three variables and showed good performance predicting major LARS after stoma reversal. The area under the curve (AUC) was 0.827 in the training group and 0.821 in the validation group; The calibration curve suggested good precision in both groups. CONCLUSIONS This novel nomogram can accurately predict the probability of major LARS occurrence after ileostomy reversal for rectal cancer patients. This model can help screen ileostomy patients with high risks and guide individualized preventive strategies before stoma reversal.

Abstract
PURPOSE Organ-sparing therapy for early-stage I/IIA rectal cancer is intended to avoid functional disturbances or a permanent ostomy associated with total mesorectal excision (TME). The objective of this phase II trial was to determine the outcomes and organ-sparing rate of patients with early-stage rectal cancer treated with neoadjuvant chemotherapy followed by transanal excision surgery (TES). METHODS This phase II trial included patients with clinical T1-T3abN0 low- or mid-rectal adenocarcinoma eligible for endoscopic resection who were treated with 3 months of chemotherapy (modified folinic acid-fluorouracil-oxaliplatin 6 or capecitabine-oxaliplatin). Those with evidence of response proceeded to transanal endoscopic surgery 2-6 weeks later. The primary end point was protocol-specified organ preservation rate, defined as the proportion of patients with tumor downstaging to ypT0/T1N0/X and who avoided radical surgery. RESULTS Of 58 patients enrolled, all commenced chemotherapy and 56 proceeded to surgery. A total of 33/58 patients had tumor downstaging to ypT0/1N0/X on the surgery specimen, resulting in an intention-to-treat protocol-specified organ preservation rate of 57% (90% CI, 45 to 68). Of 23 remaining patients recommended for TME surgery on the basis of protocol requirements, 13 declined and elected to proceed directly to observation resulting in 79% (90% CI, 69 to 88) achieving organ preservation. The remaining 10/23 patients proceeded to recommended TME of whom seven had no histopathologic residual disease. The 1-year and 2-year locoregional relapse-free survival was, respectively, 98% (95% CI, 86 to 100) and 90% (95% CI, 58 to 98), and there were no distant recurrences or deaths. Minimal change in quality of life and rectal function scores was observed. CONCLUSION Three months of induction chemotherapy may successfully downstage a significant proportion of patients with early-stage rectal cancer, allowing well-tolerated organ-preserving surgery.

Development of prediction model of low anterior resection syndrome for colorectal cancer patients after surgery based on machine-learning technique. Cancer Med 2023; 12:1501-1519. [PMID: 35899858 PMCID: PMC9883536 DOI: 10.1002/cam4.5041] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Revised: 06/18/2022] [Accepted: 07/07/2022] [Indexed: 02/05/2023] Open
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.

The Effectiveness of a Self-management Program of Bowel Dysfunction in Patients With Mid and Low Rectal Cancer After Sphincter-Preserving Surgery: A Pilot Randomized Controlled Trial. Cancer Nurs 2023; 46:67-76.

Abstract
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
BACKGROUND Low anterior resection syndrome (LARS) is a functional disorder that may follow restorative proctectomy. The aim of this study was to evaluate the long-term incidence and risk factors for LARS following surgery for rectal cancer. METHODS A retrospective study was performed on patients from a prospectively maintained database, who underwent a restorative proctectomy between January 2014 and December 2019 at Hadassah Hebrew University Medical Center. The study cohort was divided into two groups: patients following partial proctectomy with a partial mesorectal excision and a colorectal anastomosis (PME group) and patients following total proctectomy with total mesorectal excision and a coloanal anastomosis (TME group). The incidence and severity of LARS were evaluated using the LARS questionnaire. Risk factors for LARS were also evaluated. RESULTS A total of 240 patients (male: female ratio 134:106, median age 64 years [interquartile range 55-71 years]) were included in the analysis. There were 160 patients in the PME group and 80 patients in the TME group. The overall incidence of LARS was 37.4% (26.5% major LARS and 10.9% minor LARS). Major LARS was observed in 53.8% of patients who underwent TME and in 12.7% of patients who underwent PME (p < 0.001). On multivariate analysis, distance of the anastomosis from the anal verge, TME, and neoadjuvant radiotherapy were independent prognostic factors for LARS. The incidence and severity of LARS were significantly lower in patients with longer follow-up (p = 0.05). CONCLUSIONS Significant improvement in LARS can be expected with longer follow-up. Distance of the anastomosis from the anal verge, TME and neoadjuvant radiotherapy are independent risk factors for LARS.

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
Background Low anterior resection syndrome (LARS) is the most common complication after rectal cancer resection. We aimed to identify LARS' predictive factors and construct and evaluate a predictive model for LARS. Methods This retrospective study included patients with rectal cancer more than 1 year after laparoscopic or robotic-assisted surgery. We administered a questionnaire to evaluate the degree of LARS. In addition, we examined clinical characteristics with univariate and multivariate analysis to identify predictive factors for major LARS. Finally, we divided the obtained data into a learning set and a validation set. We constructed a predictive model for major LARS using the learning set and assessed the predictive accuracy of the validation set. Results We reviewed 160 patients with rectal cancer and divided them into a learning set (n = 115) and a validation set (n = 45). Univariate and multivariate analyses in the learning set showed that male (odds ratio [OR]: 2.88, 95% confidence interval [95%CI] 1.11–8.09, p = 0.03), age < 75 years (OR: 5.87, 95%CI 1.14–47.25, p = 0.03) and tumors located < 8.5 cm from the AV (OR: 7.20, 95%CI 2.86–19.49, p < 0.01) were significantly related to major LARS. A prediction model based on the patients in the learning set was well-calibrated. Conclusions We found that sex, age, and tumor location were independent predictors of major LARS in Japanese patients that underwent rectal cancer surgery. Our predictive model for major LARS could aid medical staff in educating and treating patients with rectal cancer before and after surgery.

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 Neoadjuvant chemoradiotherapy (neoCRT) followed by surgery is the standard of care for locally advanced rectal cancer (LARC), but the emergence of different drug regimens may result in different response rates. Good clinical response translates into greater sphincter preservation, but quality of life (QOL) may be impaired after treatment due to chemoradiotherapy and surgical side effects. OBJECTIVE To prospectively evaluate the impact of clinical response and surgical resection on QOL in a randomized trial comparing two different neoCRT regimens. METHODS Stage II and III rectal cancer patients were randomized to receive neoCRT with either capecitabine (group 1) or 5-Fu and leucovorin (group 2) concomitant to long-course radiotherapy. Clinical downstaging was accessed using MRI 6-8 weeks after treatment. EORTCs QLQ-C30 and CR38 were applied before treatment (T0), after neoCRT (T1), after rectal resection (T2), early after adjuvant chemotherapy (T3), and 1 year after the end of treatment or stoma closure (T4). The Wexner scale was used for fecal incontinence evaluation at T4. A C30SummaryScore (Geisinger and cols.) was calculated to compare QOL results. RESULTS Thirty-two patients were assigned to group 1 and 31 to group 2. Clinical downstaging occurred in 70.0% of group 1 and 53.3% of group 2 (p = 0.288), and sphincter preservation was 83.3% in group 1 and 80.0% in group 2 (p = 0.111). No significant difference in QOL was detected when comparing the two treatment groups after neoCRT using QLQ-C30. However, the CR38 module detected differences in micturition problems (15.3 points), gastrointestinal problems (15.3 points), defecation problems (11.8 points), and sexual satisfaction (13.3 points) favoring the capecitabine group. C30SummaryScore detected significant improvement comparing T0 to T1 and deterioration comparing T1 to T2 (p = 0.025). The mean Wexner scale score was 9.2, and a high score correlated with symptoms of diarrhea and defecation problems at T4. CONCLUSIONS QOL was equivalent between groups after neoCRT except for micturition problems, gastrointestinal problems, defecation problems, and sexual satisfaction favoring the capecitabine arm after. The overall QOL using the C30SummaryScore was improved after neoCRT, but decreased following rectal resection, returning to basal levels at late evaluation. Fecal incontinence was high after sphincter preservation. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03428529.

Abstract
Endoluminal vacuum-assisted therapy (EVT) has been introduced recently to treat colorectal anastomotic leaks in clinically stable non-peritonitic patients. Its application has been mainly reserved to low colorectal and colo-anal anastomoses. The main advantage of this new procedure is to ensure continuous drainage of the abscess cavity, to promote and to accelerate the formation of granulation tissue resulting in a reduction of the abscess cavity. The reported results are promising allowing a higher preservation of the anastomosis when compared to conventional treatments that include trans-anastomotic tube placement, percutaneous drainage, endoscopic clipping of the anastomotic defect or stent placement. Nevertheless, despite this procedure is gaining acceptance among the surgical community, indications, inclusion criteria and definitions of success are not yet standardized and extremely heterogeneous, making it difficult to reach definitive conclusions and to ascertain which are the real benefits of this new procedure. Moreover, long-term and functional results are poorly reported. The present review is focused on critically analyzing the theoretical benefits and risks of the procedure, short- and long-term functional results and future direction in the application of EVT.

Abstract
BACKGROUND The development of major low anterior resection syndrome (LARS) after low anterior resection is severely detrimental to quality of life, yet awareness of it by clinicians and patients and the frequency of treatment of LARS is unclear. STUDY DESIGN Patients who underwent low anterior resection for sigmoid or rectal cancer at a tertiary center between 2007 and 2017 (n = 798) were surveyed in 2019 to assess LARS symptoms and report medications or treatment received for LARS. LARS scores were calculated (score range 0-42) and normalized to published data on LARS prevalence in the general population in Europe, stratified by age (<50 or ≥50) and sex. RESULTS Of the 594 patients (74%) who returned the survey, 255 (43%) were identified as having major LARS (LARS score ≥30). This prevalence was significantly higher than published normative data from Denmark and Amsterdam when stratified by age greater than or less than 50 and sex. Patients with major LARS infrequently reported current use of first-line therapies (antidiarrheal medications 32%, fiber supplements 16%, and both 13%). Only 3% reported receiving second-line therapy of transanal irrigations and/or pelvic floor rehabilitation, and only 1% had undergone third-line therapy of sacral nerve stimulator implantation. CONCLUSION Major LARS is common yet seemingly underrecognized by clinicians because less than half of patients are on first-line therapy and practically none are on second- and third-line therapies. Long-term follow-up of patients after low anterior resection, improved preoperative and postoperative education, and continued symptom assessment is necessary to improve treatment of major LARS.

Abstract
Background The Low Anterior Resection Syndrome (LARS) is commonly reported after colorectal cancer surgery and significantly impairs quality of life. The prevalence and impact of LARS in the elderly after rectal cancer as well as colon cancer surgery is unclear. We aimed to describe the prevalence of LARS complaints and the impact on quality of life in the elderly after colorectal cancer surgery. Materials and Methods Patients were included from seven Dutch hospitals if they were at least one year after they underwent colorectal cancer surgery between 2008 and 2015. Functional bowel complaints were assessed by the LARS score. Quality of life was assessed by the EORTC QLQ-C30 and EORTC QLQ-CR29 questionnaires. Outcomes in patients ≥70 years were compared to a reference group of patients <70 years. Results In total 440 rectal cancer and 1183 colon cancer patients were eligible for analyses, of whom 133 (30.2%) rectal and 536 (45.3%) colon cancer patients were ≥70 years. Major LARS was reported by 40.6% of rectal cancer and 22.2% of colon cancer patients ≥70 years. In comparison, patients <70 years reported major LARS in 57.3% after rectal cancer surgery (p=0.001) and in 20.4% after colon cancer surgery (p=0.41). Age ≥70 years was independently associated with reduced rates of major LARS after rectal cancer surgery (OR 0.63, p=0.04). Patients with major LARS reported significantly impaired quality of life on almost all domains. Conclusion Elderly should not be withheld a restorative colorectal cancer resection based on age alone. However, a substantial part of the elderly colorectal cancer patients develops major LARS after surgery, which often severely impairs quality of life. Since elderly frequently consider quality of life and functional outcomes as one of the most important outcomes after treatment, major LARS and its impact on quality of life should be incorporated in the decision-making process.

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
BACKGROUND There is limited evidence on the efficacy of acupuncture in bowel dysfunction treatment. OBJECTIVE The aim of this pilot study was to investigate the potential value of acupuncture in the treatment of low anterior resection syndrome. DESIGN This was an open-design pilot study. SETTINGS This was a single-center study. PATIENTS Nine (5 female) patients with major low anterior resection syndrome were included. INTERVENTIONS All patients underwent acupuncture by a trained specialist once a week for 10 weeks. MAIN OUTCOME MEASURES Bowel function was assessed by using the low anterior resection syndrome score and the Memorial Sloan-Kettering Cancer Center bowel function instrument before the procedure, just after finishing the course of acupuncture, and 6 months after the treatment. RESULTS The average age was 56.44 (50-65; SD ±5.4). Median age was 56 years. At the end of the procedure, all patients reported significant improvement in low anterior resection syndrome symptoms: the average low anterior resection syndrome score before acupuncture was 39 (±2.7), after acupuncture it was 30.3 (±10.6), and 6 months after acupuncture it was 7.22 (±10.244; p < 0.000). The average Memorial Sloan-Kettering Cancer Center bowel function instrument score before acupuncture was 55.33 (±11.55), after the procedure it was 60 (±14.97), and 6 months later it was 70.22 (±12.2; p < 0.000). LIMITATIONS The small sample size and the fact that this is a single-center nonblinded study are limitations of this work. CONCLUSIONS Acupuncture may be effective in low anterior resection syndrome treatment and needs further evaluation. The procedure is safe and feasible.

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
BACKGROUND The purpose of this study was to describe postoperative bowel dysfunction after restorative proctectomy, and to identify factors associated with its development. METHODS Patients who underwent restorative proctectomy for rectal cancer between April 1998 and November 2018 were identified from the Hospital Episode Statistics database and linked to the Clinical Practice Research Datalink for postoperative follow-up. Bowel dysfunction was defined according to relevant symptom-based read codes and medication prescription-product codes. A Cox proportional hazards model was performed to identify factors associated with postoperative bowel dysfunction, adjusting for relevant covariates. RESULTS In total, 2,197 patients were included. The median age was 70.0 (interquartile range: 62.0-77.0) years old, and the majority (59.2%) of patients were male. After a median follow-up of 51.6 (24.0-90.0) months, bowel dysfunction was identified in 620 (28.2%) patients. Risk factors for postoperative bowel dysfunction included extremes of age (<40 years old: adjusted hazards ratio 2.35, 95% confidence interval 1.18-4.65; 70-79 years old: adjusted hazards ratio 1.25, 95% confidence interval 1.03-1.52), radiotherapy (adjusted hazards ratio 1.94, 95% confidence interval 1.56-2.42), distal tumors (adjusted hazards ratio 1.62, 95% confidence interval 1.34-1.94), history of diverting ostomy (adjusted hazards ratio 1.58, 95% confidence interval 1.33-1.89), and anastomotic leak (adjusted hazards ratio 1.48, 95% confidence interval 1.06-2.05). A minimally invasive surgical approach was protective for postoperative bowel dysfunction (adjusted hazards ratio 0.68, 95% confidence interval 0.53-0.86). CONCLUSION Bowel dysfunction was common after restorative proctectomy, and several patient, disease, and treatment-level factors were associated with its development.

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.
