The first case of obstructive jaundice secondary to a chronic afferent loop obstruction has been reported. The cause of the obstructed afferent loop was found to be a carcinoma of the gastric pouch occurring 25 years after surgery for peptic ulcer disease. The failure to develop any evidence of pancreatitis despite marked dilatation of the biliary tree and gall bladder suggests the existence of an independent functioning pancreatic sphincter, perhaps the sphincter of Boyden.
首例继发于慢性输入袢梗阻的梗阻性黄疸已被报道。发现输入袢梗阻的原因是胃小囊癌，发生于消化性溃疡病手术后25年。尽管胆管树和胆囊明显扩张，但未出现胰腺炎的任何证据，这提示存在一个独立发挥功能的胰括约肌，可能是博伊登括约肌。
