[Surgical treatment of chronic disorders of duodenal transit].

New methods of surgical management of chronic duodenal patency impairments (CDPI)--desympathization of the gastroduodenal artery and a longitudinal-sectional cruciform duodenoenteric anastomosis supplemented by the longitudinal cover of the duodenum are described. The former is intended to create a vagal dominant in the nervous control of duodenal motility and indicated in functional diseases. The latter is designed for alimentary masses and digestive juices to move from the duodenum to the abducting part of the small bowel under force, which allows it to be used in all types of CDPI. Details of surgical techniques and procedures are substantiated on the basis of the author's clinical experience. An analysis of late postoperative outcomes used in the multimodality treatment of 80 patients with associated diseases has shown their high efficiency.
