# Mucus Impaction Related to Postoperative Anastomosis Site Obstruction: A Rare Case

## TL;DR

A rare case of mucus blockage at a surgical site two days after colorectal surgery is reported, with successful treatment using a sigmoidoscope.

## Contribution

This case highlights an unusual and underreported cause of immediate postoperative anastomosis site obstruction.

## Key findings

- Mucus impaction can cause immediate postoperative anastomosis site obstruction.
- Endoscopic removal of mucus led to successful patient recovery.
- Such cases are rare and often underreported in medical literature.

## Abstract

Anastomotic stricture has an incidence rate of 6-10% and typically manifests three to six months after colorectal surgery. Immediate postoperative stricture is exceedingly rare and underreported in the literature. The possible etiology includes poor circulation, leakage, local inflammation, or infection. We report a rare case of a patient with total obstruction by mucus on the anastomosis site on postoperation day two. We used a sigmoidoscope to remove mucus material, following which the patient recovered well.
