[A unusual cause of acute pancreatitis: obstruction of the afferent loop after gastrectomy according to Bilroth II. Apropos of a case and review of the literature].

We report a case of afferent loop obstruction after Bilroth II gastrojejunostomy presenting as acute pancreatitis. This form of presentation is extremely rare; to our knowledge, only 19 cases of acute pancreatitis secondary to afferent loop occlusion in patients with prior Bilroth II gastrojejunostomy have been previously reported in the literature. Obstruction can be caused by kinking, internal herniation, adhesive bands or recurrence of gastric ulcer or cancer. Because conservative management is invariably fatal, diagnosis and surgical treatment must be performed as soon as possible. CT Scan is now considered to be the imaging method of choice for the diagnosis. A case report and review of the literature are presented.
