VASCULAR INJURIES DURING PANCREATICOBILIARY SURGERY

Fourteen cases of vascular injury during pancreatobiliary surgery have been treated at our institution. The patients' mean age was 49 years, and nine were males. Six operations were performed for chronic pancre atitis, six for cancer, and two for an inflammatory process. Operation s included 11 pancreatic resections and one laparoscopic cholecystecto my, one sphincteroplasty, and one pseudocyst drainage. Vessels injured included the portal vein (7), superior mesenteric vein (6), superior mesenteric artery (3), hepatic arteries (4), splenic vein (3). Six pat ients experienced more than one vascular injury. In all but one case, the injury was recognized and repaired during the initial operation. P rimary repair was possible in seven cases. Six cases utilized autogeno us tissue for repair. The one unrecognized injury was a right hepatic artery ligation, and a delayed repair was not possible. Follow-up demo nstrated two occlusions, one following a portal vein repair without cl inical sequela and a superior mesenteric artery repair which resulted in a small bowel stricture. The one unrecognized hepatic artery injury resulted in necrosis of the proximal common hepatic duct. Vascular in jury following pancreatobiliary injury tends to occur in the presence of pancreatitis or cancer with its associated dense adhesions and infl ammatory process. The variable anatomy of this area contributes to vas cular injuries. Immediate recognition of the injury and repair appears to yield excellent results.
