A gastroduodenostomy as part of partial gastric resection may change function and morphology of the duodenum in a typical fashion. End to side anastomosis may produce a blind pouch. An end to end anastomosis may lead to postanastomotic dilatation, which may mimick a duodenal bulb (a so called "neo -- or pseudobulb"). Abnormal duodenal peristalsis with atony may follow vagotomy, pyloroplasty, gastroduodenostomy or excisional duodenal biopsy and may thus result in functional obstruction. A blind loop syndrome may develop after bypass procedures for duodenal stenosis.
作为部分胃切除术一部分的胃十二指肠吻合术可能会以一种典型方式改变十二指肠的功能和形态。端侧吻合可能会形成一个盲袋。端端吻合可能会导致吻合口扩张，这可能会模拟十二指肠球部（即所谓的“新球部或假球部”）。迷走神经切断术、幽门成形术、胃十二指肠吻合术或十二指肠切除活检后可能会出现十二指肠蠕动异常伴无力，从而导致功能性梗阻。十二指肠狭窄旁路手术后可能会发生盲袢综合征。
