Preperitoneal herniation as a complication of tansabdominal preperitoneal patch plasty: a report of two cases

Abstract

Background: Preperitoneal herniation is a rare complication after transabdominal preperitoneal patch plasty (TAPP) and may be caused by inadequate peritoneal closure. We herein report two cases of postoperative small bowel obstruction due to preperitoneal herniation through a disrupted peritoneum. Case presentation: Two men in their 70s were admitted to our center because of small bowel obstruction after TAPP. After examinations and unsuccessful conservative treatment, emergency laparoscopic exploration was performed. Preperitoneal herniation through the disrupted peritoneum was found. The herniated small bowel was reduced and the peritoneum was properly reclosed. The patients recovered and were discharged with normal bowel function. Conclusions: Inadequate peritoneal closure may cause preperitoneal herniation and lead to postoperative small bowel obstruction and even death. Hernia surgeons can avoid this complication by improving their suture technique and paying attention to the procedure details.
