Thoracoscopic repair of iatrogenic diaphragmatic hernia following multiple abdominal surgeries: a case report

Abstract Iatrogenic diaphragmatic hernia (IDH) is a rare complication that has been reported after various interventions, including liver transplantation, liver resection and nephrectomy. A surgical procedure for IDH has not been optimized. A 56-year-old man presented to our hospital with a 1-week history of abdominal pain and nausea. His medical history included an open nephrectomy for renal cancer 8 years ago and open distal pancreatectomy for its recurrence 1.5 years ago. Enhanced computed tomography showed IDH with the fornix of the stomach herniating to the left pleural cavity, without radiographic signs of strangulation. His symptoms improved after gastric decompression with nasogastric tube placement, and he underwent elective surgery. The incarcerated stomach was repositioned, and the hernia orifice was closed and reinforced with expanded polytetrafluoroethylene mesh using a thoracoscopic procedure. The patient had an uneventful postoperative course. The operative procedure for IDH should be tailored depending on anatomical alternations after previous surgeries.
