Summary
Parastomal hernia, a common complication after ileostomy or colostomy, occurs in up to 48.1% of cases. Mesh repair offers lower recurrence rates than direct tissue repair for this condition.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Abdominal Surgery
Background:
- Parastomal hernia is a frequent complication following ileostomy or colostomy formation.
- Incidence rates vary significantly based on stoma type and follow-up duration.
Purpose of the Study:
- To review the incidence of parastomal hernia.
- To examine technical factors influencing hernia development.
- To assess the efficacy of various repair methods.
Main Methods:
- A comprehensive literature search was conducted using the Medline database.
- English language articles on parastomal hernia were identified.
- Additional relevant studies were sourced from the bibliographies of reviewed articles.
Main Results:
- Parastomal hernia incidence ranges from 1.8-48.1% for ileostomies and colostomies.
- Stoma construction techniques (e.g., site, trephine size) did not demonstrably affect hernia rates.
- Mesh repair showed lower recurrence rates (0-33.3%) compared to direct tissue repair (46-100%) or stoma relocation (0-76.2%).
Conclusions:
- Parastomal hernia incidence is highly variable (0-48.1%).
- No specific stoma construction techniques are proven to prevent herniation.
- Prosthetic mesh repair is recommended for parastomal hernias requiring surgical intervention.
