Internal Hernia in Pregnant Woman after Roux-en-Y Gastric Bypass Surgery
Laparoscopic Roux-en-Y gastric bypass is the most common obesity surgery procedure at this moment. Many of patients undergoing the procedure are women of reproductive age. This carries a risk for developing gastric bypass-related complications during pregnancy. One of the most serious risks is an internal hernia. We present a patient in late pregnancy with an internal hernia following laparoscopic Roux-en-Y gastric bypass for morbid obesity. We discuss the importance of computed tomography (CT) in the diagnosis of internal hernia and review key CT findings including the compression of superior mesenteric vein, which proved to be crucial in diagnosing an internal hernia in this patient.
