ABSTRACT
Objective To investigate the cause, the prevention, the clinical manifestation,the diagnosis and the treatment of afferent loop syndrome following Billroth-Ⅱ-subtotal gastrectomy.Methods 10 cases of afferent loop syndrome whose history of operation, clinical manifestation, imaging examinations, and treatment were analyzed.Results Laparotomy was done again for all the 10 patients. Different extent of dilated afferent loop were seen intraoperatively. 6 patients underwent the Roux-en-Y anastomosis and the other 4 patients underwent the Braun anastomosis. No patients were died perioperatively. No recurrence was observed in followed up for 2 to 5 years after the operation.Conclusions Occurrence of afferent loop syndrome is associated with the incorrect operation technique. Improving the operation technique should be emphasized for preventing afferent loop syndrome. Once the definite diagnosis of afferent loop syndrome was worked out, the laparotomy shoud be done again as soon as possible. The optional operation can choose the Billroth-Ⅰoperation, the Roux-en-Y anastomosis, the Braun anastomosis or jejunal interposition,respectively.
