Postcolonoscopy Appendicitis: A Review of 57 Cases.

Area of Science:

• Gastroenterology
• Surgical Pathology

Background:

• Postcolonoscopy appendicitis (PCA) is a rare but significant complication following colonoscopy procedures.
• Understanding the incidence, clinical features, and pathogenesis of PCA is crucial for patient management.

Purpose of the Study:

• To review and synthesize existing literature on postcolonoscopy appendicitis.
• To identify key characteristics, diagnostic methods, and treatment strategies for PCA.

Main Methods:

• A comprehensive literature search was conducted across PubMed, EMBASE, Scopus, and Google Scholar.
• 57 reported cases of postcolonoscopy appendicitis were identified and analyzed.

Main Results:

• PCA most commonly presents within 24 hours post-colonoscopy, often after diagnostic procedures.
• Clinical presentation mimics acute appendicitis, but with a higher perforation rate.
• Ultrasound and CT scans are effective diagnostic tools; treatment varies from surgery to antibiotics.

Conclusions:

• While barotrauma and direct trauma are potential causes, underlying subclinical appendiceal disease may play a role in PCA pathogenesis.
• Timely diagnosis and appropriate management are critical for successful patient outcomes in postcolonoscopy appendicitis.
