Brief Summary

Bowel dysfunction after rectal cancer resection comprises a vast array of bowel symptoms and associated quality-of-life impairment, collectively termed as low anterior resection syndrome (LARS). There are 40%-60% patients who suffer from major LARS after sphincter-preserving surgery. No consensus exists for LARS treatment or prevention. Transanal irrigation (TAI) was reported to play a helpful role in the management of major LARS and fecal incontinence. However, the preventive effect and daily accessibility need further confirmation. In this randomized trial, TAI compared with best support treatment, is used in patients who received curative low anterior resection for rectal cancer with diverting stoma, after completion of the stoma reversal. The primary outcome is the occurrence of major LARS after 6 months of the treatment.

Study Arms (2)

Transanal irrigation

EXPERIMENTAL

Transanal irrigation (TAI) is performed using the irrigation bag, electronic irrigation system, or balloon catheter with syringe. TAI is performed with up to 2000 ml tap water every 24-48 hours (3-7 times per week) over the course of 6 months.

Procedure: Transanal irrigation

Best supportive therapy

ACTIVE COMPARATOR

Best supportive therapy consists of dietary modification, pelvic floor muscle training, biofeedback, and necessary medication.

Other: Best supportive therapy
