[Two Cases of Afferent Loop Obstruction Treated with Percutaneous Bowel Drainage(PBD)]

Here, we report our experiences with 2 cases of afferent loop obstruction with percutaneous bowel drainage(PBD)and present a review of the literature. Case 1 involved a 60-year-old woman. She underwent pancreaticoduodenectomy for pancreatic cancer. Eighteen months postoperatively, a recurrence marked by a jejunal elevation and expansion on the cecal side near the porta hepatic lymph nodes appeared. We performed PBD because intestinal depression via the endoscopic approach was difficult. She was discharged from the hospital 7 days after PBD. Case 2 involved a 51-year-old woman. She underwent total gastrectomy and Roux-en-Y reconstruction for progressive stomach cancer. We detected a local recurrence in the Y anastomosis following a chief complaint of vomiting 10 months postoperatively. Fifteen months postoperatively, she developed acute pancreatitis with afferent loop syndrome. We performed PBD via a trans-liver route. The patient was discharged from the hospital 11 days after PBD. By devising a puncture route, we could safely perform PBD for an afferent loop obstruction.
