Abstract
A 72-year-old woman who had undergone laparoscopic right hepatectomy for hepatocellular carcinoma was admitted due to vomiting. Abdominal CT revealed incarceration of the transverse colon in the right thoracic cavity. A diaphragmatic hernia was diagnosed, and video-assisted thoracic surgery was performed. Diaphragmatic hernia after hepatic resection is a rare and not well-described complication. Successful thoracoscopy-assisted surgery for diaphragmatic hernia after hepatectomy is reported.
