# Iatrogenic Right-Sided Diaphragmatic Hernia After Colonoscopy

## TL;DR

A rare case of a right-sided diaphragmatic hernia occurring after a colonoscopy is reported, highlighting an unusual complication.

## Contribution

This case report adds to the limited literature on post-colonoscopy diaphragmatic hernias, particularly on the rare right-sided type.

## Key findings

- The patient developed a right-sided diaphragmatic hernia after a routine colonoscopy.
- Retrospective imaging suggested a pre-existing diaphragm defect.
- Such hernias are rare, and right-sided ones are even less common.

## Abstract

Congenital diaphragmatic hernias (CDH) occur as a result of genetic and environmental factors that occur during the early stages of fetal development. Overall, CDH are considered to be quite rare and are often discovered when patients are neonates. The patient in this case underwent a routine colonoscopy for high-risk polyps but then developed the sudden onset of cramping abdominal pain and PO (per os) intolerance. She was found to have a right-sided diaphragmatic hernia which ultimately required operative intervention. Retrospectively, a close review of prior imaging revealed a potential diaphragm defect. Post-colonoscopy diaphragmatic hernias are very rare and right-sided ones are rarer, making this case report an important addition to the literature.
