Postoperative tension pneumoperitoneum in an infant
1Sophia Clinic, 27 Old Aba Road, P.O. Box 5575, Port Harcourt, Nigeria.
Insights
A rare complication of pyloric surgery, tension pneumoperitoneum, was successfully treated by closing a pyloric fistula. This case highlights the importance of recognizing and managing this surgical complication.
Area of Science:
- Pediatric Surgery
- Gastrointestinal Surgery
- Surgical Complications
Background:
- Hypertrophic pyloric stenosis is a common surgical condition in infants.
- The Fredet-Ramstedt pyloromyotomy is the standard surgical treatment.
- Postoperative complications, though rare, require prompt recognition and management.
Observation:
- A 9-week-old infant presented with massive abdominal distension after pyloromyotomy.
- Initial imaging suggested tension pneumoperitoneum, confirmed by needle decompression.
- Distension recurred, necessitating further investigation.
Findings:
- Laparotomy revealed a pyloric fistula at the proximal pyloromyotomy site, causing the tension pneumoperitoneum.
- The fistula was distinct from the initial mucosal tear at the distal end.
- Surgical closure of the fistula led to complete resolution of symptoms.
Implications:
- This case underscores a rare but serious complication of pyloromyotomy.
- Prompt diagnosis and surgical intervention are crucial for favorable outcomes.
- Understanding fistula formation can refine surgical techniques and patient care.
Abstract:
A 9-week-old boy developed massive postoperative abdominal distension following a Fredet-Ramstedt pyloromyotomy for hypertrophic pyloric stenosis. A plain abdominal X-ray film was suggestive of a tension pneumoperitoneum. Passage of a cannula into the peritoneal space resulted in forceful expulsion of air, resulting in relief of the distension, which recurred after a few hours. At laparotomy, the tension pneumoperitoneum was due to a pyloric fistula at the proximal end of the pyloromyotomy, although a mucosal breach at the first operation had been at the distal end. Closure of the fistula resulted in complete resolution. A limited review of the literature is undertaken.
