[Creation of models of incomplete external lip-like large bowel fistula in experiment].

The method of experimental simulation of the incomplete external lip-like large bowel fistula creation was elaborated on experimental animals for studying of possibilities forapplication of hyperthermic methods of the fistula channel obliteration and disinfectioning of the neighboring anterior abdominal wall tissues. There were studied up microflora and bacterial seeding of the large bowel contents in the zone of a fistula exit as well as dynamics of changes of inflammatory processes, occurring in tissues of anterior abdominal wall, neighboring the external orifice of a fistula channel.

[Vascular risk factors for occurrence of early postoperative complications in patients after pancreaticoduodenal resection].

The results of pancreaticoduodenal resection (PDR), performed in 163 patients in 2006-2010 yrs, are summarized. In 51 (31.3%) patients the complications have occurred. All the patients are alive. The trustworthy connection was established between the rate of the early postoperative complications occurrence and the volume blood flow velocity in a portal vein as well as index of the common hepatic artery resistance before the operation. The indices of regional hemodynamics influence the results of PDR performance. The simultant vascular resection performance do not impact the operative risk level, when compared with such while a standard resection conduction. The risk of the early postoperative complications occurrence is not influenced by the antisecretory therapy regime choosed, using somatostatin analogues.
