Postoperative intestinal obstruction caused by staple-related internal hernia after laparoscopic appendectomy: a case report
DOI: 10.31744/einstein_journal/2026RC1256
Abstract
Postoperative intestinal obstruction is most commonly associated with adhesions but may also arise from unusual causes such as surgical staples adhering to adjacent structures. Although the use of endoscopic staplers in laparoscopic appendectomy is effective and generally safe, it can occasionally result in complications, including intestinal obstruction. We report the case of a 41-year-old woman who underwent surgical treatment for pelvic endometriosis, including appendectomy, and subsequently developed intestinal obstruction caused by an internal hernia formed by the entrapment of a surgical staple from the appendiceal suture line in the jejunal loop. The patient recovered uneventfully after laparoscopic release and removal of staple, with complete resolution of symptoms. This case underscores the importance of vigilance during staple application and reinforces the need for continued improvements in stapling techniques to prevent similar complications.
