Lemniscate intestinal loop through an internal hernia after Roux-en-Y gastric bypass cause of coecum mobile. A case report

Abstract

The internal hernia is a typical complication after laparoscopic Roux-en-Y gastric bypass surgery. In most cases, there are chronic symptoms that only lead to a diagnostic laparoscopy during the diagnostic exclusion procedure. Less common is acute internal hernia with devastating pain, ileus symptoms and even the development of intestinal gangrene. Although this case describes a typical constellation, it posed a particular challenge because it resulted in mesenteric lemniscate-like torsion through the Petersen pouch.
