# Laparoscopic Abdominoperineal Resection for Ischemic Colitis after Laparoscopic Partial Resection of the Descending Colon: Case Report

## TL;DR

This case report describes a rare instance of ischemic colitis requiring surgery after a laparoscopic partial colon resection.

## Contribution

The novelty lies in presenting a rare post-surgical complication and its management through laparoscopic abdominoperineal resection.

## Key findings

- Ischemic colitis occurred 2 years after laparoscopic partial resection of the descending colon.
- Laparoscopic abdominoperineal resection was performed due to failure of conservative treatment.
- Histopathological confirmation of ischemic colitis was achieved post-surgery.

## Abstract

With advances in laparoscopic surgery, more sophisticated vessel-preserving techniques have become standardized. Laparoscopic partial colectomy aimed at maximizing colonic preservation is now widely performed. Along with this trend, cases of ischemic colitis developing after colorectal cancer surgery have occasionally been reported; however, cases requiring surgical resection remain exceedingly rare. Here, we report a case of ischemic colitis that developed 2 years and 2 months after partial laparoscopic resection of the descending colon, necessitating laparoscopic abdominoperineal resection.

A 65-year-old male underwent laparoscopic partial resection of the descending colon with preservation of the superior rectal artery to treat descending colon cancer at the age of 62 years. Two years and 2 months postoperatively, the patient developed left abdominal pain. Contrast-enhanced CT and colonoscopy revealed ischemic colitis. Because conservative management was ineffective, surgical resection was required, and laparoscopic abdominoperineal resection was performed. Histopathological examination confirmed a diagnosis of ischemic colitis. The patient was discharged 48 days after surgery.

Ischemic colitis occurring after colorectal cancer surgery is rare, and surgical intervention is extremely uncommon in such cases. Here, we present this case with a review of the relevant literature.
