Pelvic floor muscle training for the prevention and management of low anterior resection syndrome in patients with rectal cancer: An evidence-based summary

Objective

This study aims to summarize the best available evidence on the effectiveness of pelvic floor muscle training (PFMT) in preventing and managing low anterior resection syndrome (LARS) among patients with rectal cancer, with the goal of enhancing quality of care.

Methods

A systematic search was conducted across databases, including BMJ Best Practice, UpToDate, WHO, GIN, UK NICE, NGC, SIGN, RNAO, NCCN, JBI Library, Cochrane Library, CINAHL, Web of Science, Embase, OVID, PubMed, Chinese Wanfang, CNKI, SinoMed, and VIP, covering publications from inception through June 30, 2024. We targeted clinical decisions, guidelines, evidence summaries, expert consensus statements, systematic reviews, and randomized controlled trials related to PFMT for LARS in patients with rectal cancer. Two independent reviewers assessed the quality of the literature and extracted key findings.

Results

A total of 15 articles were included, yielding 21 pieces of evidence across six core areas: multidisciplinary management, bowel function risk screening and assessment, the purpose and target population for PFMT, pre-exercise instructions, exercise regimens, and exercise feedback.

Conclusions

The summarized 21 recommendations provide guidance for integrating PFMT into care plans for patients with rectal cancer and LARS. However, given that evidence originates from diverse clinical settings, considerations such as the local health care environment should be evaluated before implementation. Future research should focus on optimizing PFMT regimens to improve bowel function outcomes in patients with rectal cancer, refining exercise protocols, and gathering further data to enhance clinical application.
