Core Tip

Core Tip: The incidence of internal hernias has recently increased in concordance with the increasing popularity of laparoscopic surgery. Protein-losing enteropathy (PLE) is a rare syndrome involving gastrointestinal protein loss. However, its relationship with internal Petersen’s hernias remains unknown. This report presents a rare case of PLE caused by a jejunum segmental ulcer following an internal hernia in Petersen’s space. PLE and extensive jejunal ulceration may follow the reduction of Petersen's hernia. Double-balloon enteroscopy revealed the etiology of PLE and enabled minimal bowel resection in this case.
