Delorme surgery for colonic mucosal prolapse after intersphincteric resection.

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Mucosal prolapse at the anastomosis site is a unique long-term complication of intersphincteric resection (ISR).
• This complication negatively impacts patients' quality of life due to worsened anal function and local symptoms.
• Assessing surgical outcomes for Delorme surgery in these patients is crucial.

Purpose of the Study:

• To evaluate the surgical outcomes of Delorme surgery for colonic mucosal prolapse following ISR.
• To assess the improvement in anal function and local symptoms post-Delorme surgery.
• To determine the recurrence rate of colonic mucosal prolapse after Delorme surgery.

Main Methods:

• Retrospective analysis of 33 patients who underwent Delorme surgery for postoperative colonic mucosal prolapse after ISR.
• Evaluation of anal function using Wexner's incontinence score.
• Assessment of local anal symptom improvement and prolapse recurrence.

Main Results:

• Local anal symptoms improved in all 33 patients (100%) post-Delorme surgery.
• The average Wexner's incontinence score improved from 15.1 to 12.9.
• A 15% recurrence rate of colonic mucosal prolapse was observed, with reoperation in affected cases.

Conclusions:

• Delorme surgery offers clinical benefits for colonic mucosal prolapse following ISR.
• The procedure effectively improves local anal symptoms and offers a slight enhancement in anal function.
• Delorme surgery is a viable option for managing this specific postoperative complication.
