Biofeedback magnetic stimulation improves postoperative bowel dysfunction after rectal cancer surgery.

Area of Science:

• Gastroenterology
• Surgical Oncology
• Rehabilitation Medicine

Background:

• Postoperative bowel dysfunction (PBD) is a common complication following rectal cancer surgery.
• Effective management strategies are crucial for improving patient outcomes and quality of life.

Purpose of the Study:

• To assess the clinical efficacy of biofeedback magnetic stimulation (BFMS) for PBD after rectal cancer surgery.
• To identify predictors of treatment success in managing PBD.

Main Methods:

• A retrospective cohort study included 158 patients undergoing low anterior resection.
• Patients received either BFMS (observation group, n=83) or conventional rehabilitation (control group, n=75).
• Outcomes measured included defecation function, anorectal manometry, Wexner scores, and QLQ-CR29 quality-of-life scores.

Main Results:

• The BFMS group demonstrated significantly improved defecation function, anorectal pressure, and quality of life at 2 and 3 months postoperatively (P<0.05).
• Adverse reaction rates were similar between groups.
• Multivariate analysis identified anastomotic leakage, ultra-low rectal cancer, interspinous diameter, and treatment method as independent predictors of outcomes (P<0.05).

Conclusions:

• BFMS is a safe and effective therapy for PBD following rectal cancer surgery.
• BFMS enhances bowel function and patient quality of life.
• Anatomical and surgical factors are key predictors of treatment response.
