Abstract
AIM Attention is increasingly being turned to functional outcomes as being central to colorectal cancer (CRC) survivorship. The current literature may underestimate the impact of evacuatory dysfunction on patient satisfaction with bowel function after anterior resection (AR) for CRC. The aim of this study was to investigate the impact of post-AR symptoms of storage and evacuatory dysfunction on patient satisfaction and health-related quality of life (HRQoL). METHOD A cross-sectional study was performed at an Australian hospital of patients post-AR for CRC (2012-2021). The postoperative bowel function scores used were: low anterior resection syndrome (LARS), St Mark's incontinence, Cleveland Clinic constipation and Altomare obstructive defaecation syndrome scores. Eight 'storage' and 'evacuatory' dysfunction symptoms were derived. A seven-point Likert scale measured patient satisfaction. The SF36v2® measured HRQoL. Linear regression assessed the association between symptoms, patient satisfaction and HRQoL. RESULTS Overall, 248 patients participated (mean age 70.8 years, 57.3% male), comprising 103 with rectal cancer and 145 with sigmoid cancer. Of the symptoms that had a negative impact on patient satisfaction, six reflected evacuatory dysfunction, namely excessive straining (p < 0.001), one or more unsuccessful bowel movement attempt(s)/24 h (p < 0.001), anal/vaginal digitation (p = 0.005), regular enema use (p = 0.004), toilet revisiting (p = 0.004) and >10 min toileting (p = 0.004), and four reflected storage dysfunction, namely leaking flatus (p = 0.002), faecal urgency (p = 0.005), use of antidiarrhoeal medication (p = 0.001) and incontinence-related lifestyle alterations (p < 0.001). A total of 130 patients (53.5%) had 'no LARS', 56 (23.1%) had 'minor LARS' and 57 (23.4%) had 'major LARS'. Fifty-seven (44.5%) patients classified as having 'no LARS' had evacuatory dysfunction. CONCLUSION Postoperative storage and evacuatory dysfunction symptoms have an adverse impact on patient satisfaction and HRQoL post-AR. The importance of comprehensively documenting symptoms of evacuatory dysfunction is highlighted. Further research is required to develop a patient satisfaction-weighted LARS-specific HRQoL instrument.

Challenges in evaluating pelvic floor physiotherapy based strategies in low anterior resection syndrome: a systematic review and qualitative analysis. Colorectal Dis 2024; 26:258-271. [PMID: 38173138 DOI: 10.1111/codi.16839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 11/08/2023] [Accepted: 11/22/2023] [Indexed: 01/05/2024]
Abstract
AIM Physiotherapy is an established treatment strategy for low anterior resection syndrome (LARS). However, data on its efficacy are limited. This is in part due to the inherent challenges in study design in this context. This systematic review aims to analyse the methodology of studies using pelvic floor physiotherapy for treatment of LARS to elucidate the challenges and limitations faced, which may inform the design of future prospective trials. METHODOLOGY A systematic review of the literature was undertaken through MEDLINE, Embase and Cochrane Library, yielding 345 unique records for screening. Five studies were identified for review. Content thematic analysis of study limitations was carried out using the Braun and Clarke method. Line-by-line coding was used to organize implicit and explicit challenges and limitations under broad organizing categories. RESULTS Key challenges fell into five overarching categories: patient-related issues, cancer-related issues, adequate symptomatic control, intervention-related issues and measurement of outcomes. Adherence, attrition and randomization contributed to potential bias within these studies, with imbalance in the baseline patient characteristics, particularly gender and baseline pelvic floor function scores. Outcome measurements consisted of patient-reported measures and quality of life measures, where significant improvements in bowel function according to patient-reported outcome measures were not reflected in the quality of life scores. CONCLUSION Upcoming trial design in the area of pelvic floor physiotherapy for faecal incontinence related to rectal cancer surgery can be cognisant of and design around the challenges identified in this systematic review, including the reduction of bias, exclusion of the placebo effect and the potential cultural differences in attitude towards a sensitive intervention.

[PMID: 38099961 DOI: 10.1007/s10151-023-02879-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 11/12/2023] [Indexed: 12/18/2023]
Abstract
BACKGROUND The literature is inconclusive when comparing health-related quality of life following restorative anterior resection (AR) compared with abdominoperineal resection (APR). Consideration of functional outcomes may explain this inconsistency. The aim of this study was to compare health-related quality of life in patients post-anterior resection, stratified by low anterior resection syndrome score, and post-abdominoperineal resection patients. METHODS A cross-sectional study of consecutive patients post APR and AR for rectal or sigmoid adenocarcinoma at a tertiary centre in Sydney, Australia (Jan 2012- Dec 2021) was performed. HRQoL outcomes (SF36v2 physical [PCS] and mental component summary [MCS] scores) were compared between APR and AR patients, with subgroup analyses stratifying AR patients according to LARS score (no/minor/major). Age- and gender-adjusted comparisons were performed by linear regression. RESULTS Overall, 248 post-AR patients (57.3% male, mean age 70.8 years, SD 11.6) and 64 post-APR patients (62.5% male, mean age 68.1 years, SD 13.1) participated. When stratified by LARS, 'major LARS' had a similar negative effect on age-and sex-adjusted PCS scores as APR. 'No LARS' (p < 0.001) and 'minor LARS' (p < 0.001) patients had higher PCS scores compared to post-APR patients. 'Major LARS' had a similarly negative effect on MCS scores compared with post-APR patients. MCS scores were higher in 'no LARS' (p = 0.006) compared with APR patients. CONCLUSIONS Postoperative bowel dysfunction significantly impacts health-related quality of life. Patients with 'major LARS' have health-related quality of life as poor as those following APR. This requires consideration when counselling patients on postoperative health-related quality of life, especially where poor postoperative bowel function is anticipated following restorative surgery.

Abstract
INTRODUCTION After rectal cancer surgery, a majority of patients suffer from sequelae known as low anterior resection syndrome (LARS). It is a collection of symptoms consisting of flatus and/or stool incontinence, evacuation frequency, re-evacuation and urgency. The circadian hormone, melatonin, has shown to possess anti-inflammatory properties, and in high doses, it reduces bowel movements. The aim of the study is to investigate if locally administered melatonin has an alleviating effect on LARS. Secondarily, the effect of melatonin on bowel movements, other patient-reported symptoms, quality of life, depression, anxiety, sleep disturbances, motilin levels and rectal mucosa histology will be examined. METHODS AND ANALYSIS This is a randomised, placebo-controlled, double-blinded, two-period crossover trial. The participants are randomised to 28 days of 25 mg melatonin administered rectally via an enema daily (or placebo) followed by a 28-day washout and then 28 days of placebo (or melatonin). Three participants will be included in an internal feasibility test. They will receive 25 mg of melatonin daily for 28 days. Data from these participants will be used to assess the feasibility of the rectally administered melatonin and to analyse the course of recruitment and outcome measurements. Afterwards, 18 participants will be included in the crossover trial. The severity of the LARS symptoms will be evaluated using the LARS Score on the first and last day of each treatment period. ETHICS AND DISSEMINATION The Regional Ethics Committee, the Danish Medicines Agency and the Data and Development Support in Region Zealand approved this study. The study will be performed according to the Helsinki II declaration. Written informed consent will be obtained from all participants. The results of the study will be submitted to peer-reviewed journals for publication and presented at congresses. TRIAL REGISTRATION NUMBERS EudraCT Registry (2020-004442-11) and ClinicalTrial.gov Registry (NCT05042700).

Abstract
INTRODUCTION It is estimated that approximately 70% of patients with rectal cancer who undergo surgery will suffer from Low Anterior Resection Syndrome (LARS). In the last decades, sacral neuromodulation (SNM) has been widely used in urinary dysfunction and in faecal incontinence refractory to medical treatment. Its application in LARS has been investigated and has shown promising results. The paper's aim is to present a systematic review and meta-analysis of the available literature and evaluate the therapeutic success of SNM in patients with LARS. METHODS A systematic search was performed in international health-related databases: Cochrane Library, EMBASE, PubMed and SciELO. No restrictions on year of publication or language were applied. Retrieved articles were screened and selected according to set inclusion criteria. Data items were collected and processed for each included article and a meta-analysis was done according to the PRISMA guidelines. The primary outcome was the number of successful definitive SNM implants. Further outcomes included changes in bowel habits, incontinence scores, quality of life scores, anorectal manometry data and complications. RESULTS A total of 18 studies were included, with 164 patients being submitted to percutaneous nerve evaluation (PNE) with 91% responding successfully. During follow-up of therapeutic SNM some devices were explanted. The final clinical success rate was 77% after permanent implant. Other outcomes, such as the frequency of incontinent episodes, faecal incontinence scores, quality of life scores were overall improved after SNM. The meta-analysis showed a decrease in 10.11 incontinent episodes/week; a decrease of 9.86 points in the Wexner score and an increase in quality of life of 1.56 (pooled estimate). Changes in anorectal manometry were inconsistent. Local infection was the most common post-operative complication, followed by pain, mechanical issues, loss of efficacy and haematoma. DISCUSSION/CONCLUSION This is the largest systematic review and meta-analysis concerning the use of SNM in LARS patients. The findings support the available evidence that sacral neuromodulation can be effective in the treatment of LARS, with significant improvement in total incontinent episodes and patients´ quality of life.

High ligation versus low ligation of the inferior mesenteric artery in laparoscopic rectal cancer surgery: a retrospective study on surgical and long-term outcome. Langenbecks Arch Surg 2023; 408:249. [PMID: 37380790 DOI: 10.1007/s00423-023-02980-8] [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: 06/19/2022] [Accepted: 06/12/2023] [Indexed: 06/30/2023]
Abstract
BACKGROUND In laparoscopic low anterior resection for rectal cancer surgery, there has been controversy to whether the inferior mesenteric artery (IMA) should be ligated at the origin of its aorta (high ligation (HL)) or below the branches of the left colonic artery (LCA) (low ligation (LL)). This study was intended to clarify oncological outcome and long-term prognosis of retrospective analysis. METHODS Analyzed the cases who underwent laparoscopic low anterior resection (LAR) in Shanghai Ruijin Hospital from January 2015 to December 2016, 357patients scheduled into 2 groups according to the level of IMA ligation: HL (n = 247) versus LL (n = 110). RESULTS The primary endpoint is long-term outcomes, and the secondary endpoint is the incidence rate of major postoperative complications. There were no significant differences in 5-year overall survival (P = 0.92) and 5-year disease-free survival (P = 0.41). There were no differences between the clinical baseline levels in each group. The incidence of low anterior resection syndrome (LARS) in the two groups was statistically significant (P = 0.037). No significant differences were observed in operative time (P = 0.092) and intraoperative blood loss (P = 0.118). In the HL group, 6 cases (2.4%) had additional colonic excision due to poor anastomotic blood supply; none of the colonic anastomosis in the low ligation group had ischemic manifestations, and length from the proximal margin (P = 0.076), length from the distal margin (P = 0.184), the total number of lymph nodes excised (P = 0.065), and anastomotic leakage incidence (P = 0.33). CONCLUSION Low ligation of the IMA which reserved LCA with vascular root lymph node dissection in laparoscopic low anterior resection for rectal cancer surgery may help protect the blood supply of the anastomosis, and will not increase postoperative complications while enhance recovery, without compromising radical excision and long-term prognosis.

Abstract
INTRODUCTION Low anterior resection syndrome (LARS) involves bowel dysfunction after sphincter-preserving surgery for rectal resection that significantly impacts patients' quality of life (QoL). The improvement of LARS largely depends on patient self-management behaviour; however, insufficient information about supportive care and weak awareness of self-management lead to poor self-management behaviour. Motivational interviewing (MIs) explore and change patients' ambivalence during the conversation, thereby changing and maintaining healthy behaviours to enhance effective participation. In recent years, mobile health has been widely used in clinical practice, providing continuous information support and remote interaction. However, current online information on LARS is suboptimal, websites are highly variable, important content is often lacking and the material is too complex for patients. Therefore, this study will evaluate the impacts of a remote LARS interaction management intervention based on a WeChat applet ('e-bowel safety') and MIs on patients with LARS. METHODS AND ANALYSIS This study will be a single-blind, two-arm randomised controlled trial involving patients with LARS in three tertiary grade A general hospitals who will be randomised into two groups. The intervention group will use the 'e-bowel safety' applet and the intervention team will conduct a monthly MI about syndrome management. The control group will receive an information booklet that contains the same information as that provided in the 'e-bowel safety' informational module. The intervention will last for 3 months, followed by 3 months of follow-up. The primary outcome will be global QoL; the secondary outcomes will include bowel function, social support, self-management measured at the baseline, 3 months and 6 months for three times and patients' thinkings at the end of the intervention (at 3 months). ETHICS AND DISSEMINATION Ethics approval was granted by the Clinical Medical Research Ethics Committee of the First Affiliated Hospital of Anhui Medical University (PJ2022-07-53). TRIAL REGISTRATION NUMBER Chinese Clinical Trial Registry (ChiCTR2200061317).

Preoperative short-course radiation therapy with PROtons compared to photons in high-risk RECTal cancer (PRORECT): Initial dosimetric experience. Clin Transl Radiat Oncol 2022; 39:100562. [PMID: 36582423 PMCID: PMC9792362 DOI: 10.1016/j.ctro.2022.100562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 12/08/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022] Open
Abstract
Background and purpose Neoadjuvant short-course radiotherapy (SCRT) followed by full-dose systemic chemotherapy is an established treatment modality in locally advanced rectal cancer (LARC). Until recently, SCRT has been exclusively delivered with photons. Proton beam therapy (PBT) may minimize acute toxicity, which in turn likely impacts favorably on the tolerability to subsequent chemotherapy. The aim of this study is a dosimetric comparison between SCRT with photons and protons in the randomized phase II trial PRORECT (NCT04525989). Materials and methods From June 2021 to June 2022, twenty consecutive patients with LARC have been treated according to study protocol. For each patient, both a VMAT and a PBT treatment plans have been generated and compared pairwise. Results Dose-volume histogram (DVH) analysis revealed that SCRT with protons significantly reduced radiation dose to pelvic organs at risk including bladder, bones, and bowel in comparison to SCRT with photons. Photon and proton treatment plans had equivalent conformity and homogeneity indexes. Conclusion Preoperative SCRT with protons offers a significant reduction of radiation dose to normal tissues compared with current photon-based radiotherapy technique. Demonstrated dosimetric advantages may translate into measurable clinical benefits in patients with LARC. Clinical implications of the dosimetric superiority of SCRT with protons will be presented in the coming reports from the PRORECT trial.

[PMID: 36356956 DOI: 10.1111/codi.16412] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 08/29/2022] [Accepted: 10/09/2022] [Indexed: 11/12/2022]
Abstract
AIM Low anterior resection syndrome (LARS) has a large impact on patients' quality of life. Several heterogeneous intervention pathways are suggested in the literature. The steps and timing of the different steps in the pathways are unclear. This systematic scoping review aims to map the range of intervention pathways for LARS after sphincter-saving rectal cancer surgery. METHODS A search was undertaken on four databases (CINAHL, EMBASE, PubMed, and Web of Science). Any type of paper describing intervention pathways for patients with LARS following sphincter-saving surgery was included. Excluded were patients with a stoma, no full paper, no intervention pathway and not being written in English or Dutch. The review was registered with Open Science Framework (10.17605/OSF.IO/JB5H8). Narrative synthesis of the results was performed by charting and summarising key results. RESULTS A total of 373 records were screened and 12 papers were included. There was a high variability among the intervention pathways, including which patients should be included. The number of pathway steps ranged from 2-6. Most intervention pathways were treatment-led. Intervention options ranged from conservative measures to a permanent stoma. Pathway flow was highly variable and sometimes not well described, with different or no timings provided for the start, progression, or end of the pathways. Three studies discussed the use of a nurse to coordinate the pathway. CONCLUSION This systematic scoping review shows that despite similarities in treatment options there are variations in which treatments are included, when treatments should be instigated, and even which patients should be treated.

Abstract
BACKGROUND A total mesorectal excision for rectal cancer-although nerve- and sphincter-sparing-can give rise to significant bowel symptoms, commonly referred to as low anterior resection syndrome (LARS). The exact pathophysiology of this syndrome still remains largely unknown, and the impact of radical surgery on colonic motility has only been scarcely investigated. METHODS High-resolution colon manometry was performed in patients, 12-24 months after restoration of transit. Patients were divided into two groups: patients with major LARS and no/minor LARS, according to the LARS-score. Colonic motor patterns were compared, and the relationship of these patterns with the LARS-scores was investigated. KEY RESULTS Data were analyzed in 18 patients (9 no/minor LARS, 9 major LARS). Cyclic short antegrade motor patterns did occur more in patients with major LARS (total: p = 0.022; post-bisacodyl: p = 0.004) and were strongly correlated to LARS-scores after administering bisacodyl (p < 0.001). High amplitude propagating contractions (HAPC's) that started in the proximal colon and ended in the mid-section of the colon occurred significantly less in patients with major LARS compared with patients with no/minor LARS (p = 0.015). CONCLUSIONS AND INFERENCES The occurrence of more cyclic short antegrade motor patterns and less HAPC's (from the proximal to the mid-colon) is more prevalent in patients with major LARS. These findings help to understand the differences in pathophysiology in patients developing major versus no/minor bowel complaints after TME for rectal cancer.

Abstract
Low anterior resection syndrome (LARS) is a collection of symptoms that can occur as a result of a low anterior resection for bowel cancer. Transanal irrigation (TAI) can be used to manage these symptoms. This article describes a retrospective audit of 15 patients who were using TAI to manage symptoms of LARS. The aim of the audit was to ascertain whether the use of TAI improved outcomes for these patients. The data suggest that TAI has reduced both the frequency of bowel movements and episodes of faecal incontinence. Those patients using higher volumes of water seem to have experienced more benefit than those patients using lower volumes of water. These findings are consistent with current literature around TAI for LARS and suggest research into optimum volume of water would be beneficial.

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

Safety and efficacy of side-to-end anastomosis versus colonic J-pouch anastomosis in sphincter-preserving resections: an updated meta-analysis of randomized controlled trials. World J Surg Oncol 2021; 19:130. [PMID: 33882952 PMCID: PMC8061176 DOI: 10.1186/s12957-021-02243-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Accepted: 04/14/2021] [Indexed: 12/17/2022] Open
Abstract
Background The application of side-to-end anastomosis (SEA) in sphincter-preserving resection (SPR) is controversial. We performed a meta-analysis to compare the safety and efficacy of SEA with colonic J-pouch (CJP) anastomosis, which had been proven effective in improving postoperative bowel function. Methods The protocol was registered in PROSPERO under number CRD42020206764. PubMed, Embase, Web of Science, and the Cochrane Register of Controlled Trials databases were searched. The inclusion criteria were randomized controlled trials (RCTs) that evaluated the safety or efficacy of SEA in comparison with CJP anastomosis. The outcomes included the pooled risk ratio (RR) for dichotomous variables and weighted mean differences (WMDs) for continuous variables. All outcomes were calculated with 95% confidence intervals (CI) by STATA software (Stata 14, Stata Corporation, TX, USA). Results A total of 864 patients from 10 RCTs were included in the meta-analysis. Patients undergoing SEA had a higher defecation frequency at 12 months after SPR (WMD = 0.20; 95% CI, 0.14–0.26; P < 0.01) than those undergoing CJP anastomosis with low heterogeneity (I2 = 0%, P = 0.54) and a lower incidence of incomplete defecation at 3 months after surgery (RR = 0.28; 95% CI, 0.09–0.86; P = 0.03). A shorter operating time (WMD = − 17.65; 95% CI, − 23.28 to − 12.02; P < 0.01) was also observed in the SEA group without significant heterogeneity (I2 = 0%, P = 0.54). A higher anorectal resting pressure (WMD = 6.25; 95% CI, 0.17–12.32; P = 0.04) was found in the SEA group but the heterogeneity was high (I2 = 84.5%, P = 0.84). No significant differences were observed between the groups in terms of efficacy outcomes including defecation frequency, the incidence of urgency, incomplete defecation, the use of pads, enema, medications, anorectal squeeze pressure and maximum rectal volume, or safety outcomes including operating time, blood loss, the use of protective stoma, postoperative complications, clinical outcomes, and oncological outcomes. Conclusions The present evidence suggests that SEA is an effective anastomotic strategy to achieve similar postoperative bowel function without increasing the risk of complications compared with CJP anastomosis. The advantages of SEA include a shorter operating time, a lower incidence of incomplete defecation at 3 months after surgery, and better sphincter function. However, close attention should be paid to the long-term defecation frequency after SPR.

Abstract
Bowel function is increasingly considered as an important outcome for patients undergoing surgery for colorectal cancer. Increasing technical skills and technological advances have meant fewer patients require a long-term stoma but this comes at the cost, often, of poor function. With a larger range of treatment options available for a given cancer, both function and oncology should be considered in parallel when counselling patients before surgery. In the perioperative phase, bowel function can be improved with minimally invasive surgery and enhanced recovery after surgery protocols, with limited evidence for targeted medical therapies. Early detection and sound management of surgical complications such as anastomotic leak and stricture can mitigate their adverse effects on bowel function. Long-term gastrointestinal dysfunction manifests as diarrhoea and low anterior resection syndrome for colon and rectal cancer respectively. Multi-modal strategies for low anterior resection syndrome are emerging to improve significantly quality of life after restorative rectal cancer surgery.

Abstract
PURPOSE Bowel dysfunction is common after anterior resection for colorectal cancer (CRC). Pelvic floor rehabilitation (PFR) may improve functional outcomes after surgery. This review aimed to evaluate the efficacy of PFR for patients with bowel symptoms after anterior resection. METHODS MEDLINE, CINHAL, PUBMED, EMBASE, Scopus, PsycINFO, Web of Science, PEDRO and Cochrane Library were searched from inception to June 2019. A final search was performed on 11 July 2020. Randomised controlled trials (RCTs), cohort studies, case-control studies and case series of bowel dysfunction after CRC surgery and PFR were eligible for review. Outcome measures were bowel function changes measured by patient-reported outcomes and manometric measurement. Risk of bias assessments using Methodological Index for Non-Randomized Studies (MINORS) tool and Newcastle Ottawa Scale (NOS) were conducted. RESULTS Eleven trials met eligibility criteria: four retrospective studies and seven prospective, non-randomised controlled studies. A total of 516 participants were included, of which 455 received PFR. Functional outcomes were measured by bowel functional outcome questionnaires, patient diary, anorectal manometry and three studies measured quality of life. Faecal incontinence was improved in seven studies, and bowel frequency also decreased in five studies. The mean MINORS score was 10 (8-13) out of 16 in non-comparative groups and 18 (16-22) out of 24 in comparative groups; the NOS was 4.2 (3-7) out of 9. The overall risk of bias was high in most studies. CONCLUSIONS PFR appears to be beneficial for improving bowel function after anterior resection for CRC. However, the studies included had methodological limitations, so further investigation on the effectiveness of PFR is warranted.
