Laparoscopic repair of foramen of Winslow hernia

Internal hernias have been gaining attention in recent years in both surgical and radiologic literature, particularly in morbidly obese patients who have undergone the increasingly common laparoscopic Roux-Y gastric bypass. We submit a video of a patient with a history of laparoscopic Roux-Y gastric bypass who presented with a symptomatic foramen of Winslow hernia, a rare internal hernia which occurs as a distinct entity from the more commonly found Petersen’s hernia in this population. It has become apparent that small bowel, colon, and even gallbladder can herniate into the lesser sac through this naturally-occurring anatomic defect. Even amongst hernia experts, this diagnosis is infrequent enough to preclude agreement on its pathogenesis, natural history, and treatment recommendations. The video demonstrates the relevant preoperative imaging along with the successful laparoscopic reduction and repair of the hernia defect.
