Anastomose coledocoduodenal término-lateral em plano único com eversão da parede do colédoco em suínos

摘要: PURPOSE: This article aims to study the one layer end side choledochusduodenal anastomosis creating a "neopapila" which, because of mucosa recovering it, would prevent stenosis. METHODS: Thirty male pigs were distributed within 3 equal groups = Group I (control) - conventional anastomosis. II (experiment)- with evertion choledochus wall (neopapila). III (sham)- isolation and mobilization biliar tract no choledocotomy. We got flow pressure (pre postoperative) monitorized on 15 PO day animals went trough an endoscopy 30 they operated tissues analysed under macro microscopic view. RESULTS: Regarding manometry there differences between all but III. Animals in showed intestinal metaplasia diminished elastic fibers choledochus. All choledoco dilation. CONCLUSION: The proposed technique allowed same results as standard technique.
