Healed colonic diverticular perforations can mimic polyps during colonoscopy. This rare finding highlights the importance of recognizing granulation tissue to avoid misdiagnosis and guide future surgical interventions.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Endoscopy
Background:
- Sealed perforation of colonic diverticulum is common.
- Interval endoscopy can differentiate diverticular from malignant perforation.
- A healed diverticular perforation mimicking a polyp is an uncommon colonoscopy finding.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
