Fig. 1. Benign afferent loop obstruction in a 41- year-old male after pylorus-preserving pancreaticoduodenectomy. (A) Coronal plan of computed tomography (CT) shows dilated fluid-filled afferent loop (capital ‘A’) with obstruction point (black arrows). (B) Tubography after percutaneous transhepatic duodenal drainage reveals passage disturbance of afferent loop (capital ‘A’) at obstruction point (black arrows), same as CT scan. (C) A 20 mm × 6 cm balloon (asterisk) dilatation of obstruction point in afferent loop (capital ‘A’) was performed. (D) A 14-Fr straight type indwelling catheter (white arrows) was placed.
