Insights
A rare umbilical fistula in a young boy developed after inguinal hernia repair. Surgical removal revealed granulomatous tissue with silk ligature, highlighting a potential complication of the procedure.
Area of Science:
- Pediatric Surgery
- Surgical Complications
- Urology
Background:
- Inguinal hernia repair is a common pediatric surgical procedure.
- Acquired umbilical fistula is a rare but documented complication following herniorrhaphy.
Observation:
- A 2-year, 9-month-old boy presented with an umbilical fistula post-inguinal hernia repair.
- Fistulography revealed a duct connecting the umbilicus to the previous inguinal surgical site.
Findings:
- Pathological examination of the excised fistula showed granulomatous tissue.
- Silk ligature was identified within the granulomatous tissue, indicating a foreign body reaction.
Implications:
- This case underscores the importance of meticulous surgical technique during inguinal hernia repair.
- Awareness of acquired umbilical fistula as a potential complication is crucial for timely diagnosis and management.
Abstract:
A 2-year, 9-month-old boy had an umbilical fistula after repair of an inguinal hernia at 8 months of age. Fistulography findings showed a duct running from the umbilicus toward the inguinal wound. Pathological finding of the surgically removed fistula demonstrated granulomatous tissues containing silk ligature. Acquired umbilical fistula is a rare complication of inguinal herniorrhaphy. Its clinical details as well as a review of the previously reported four cases are presented.
