Abstract:
Petersen's hernia is a rare internal hernia occurring after any type of gastrojejunal anastomosis. This type of internal hernia after laparoscopic gastrectomy with Roux-en-Y reconstruction for obesity treatment has been reported frequently. However, reports about Petersen's hernia after gastrectomy with Billroth II gastrojejunostomy for gastric cancer are relatively rare. To diagnose internal hernia, whirl sign has been reported to be a sensitive predictor of internal hernia. However, it is hard to diagnose a specific type of internal hernia. We report a case of Petersen's hernia after radical subtotal gastrectomy with Billroth II gastrojejunostomy for gastric cancer with an unreported specific computed tomography finding that suggests Petersen's hernia.
