Objective: By inflammation and/or mechanical compression chronic pancreatitis (CP) frequently<br />

leads to compression or thrombosis of portalvenous vessels with, in some of these<br />

patients, regional or generalized portal hypertension. Less frequently arterial involvement may<br />

lead to arterial collaterals. In some reports surgery for CP in patients with concomitant vascular<br />

involvement has been associated with a higer complication rate or even mortality. We, therefore,<br />

analyzed our twelve-year experience with surgery for CP regarding postoperative morbidity<br />

depending on vascular involvement (Vi)<br />

Methods: From 1994 to 2005 273 patients un<strong>der</strong>went resectional surgery for complications<br />

of CP (110 PPPD, 105 duodenum-preserving head resections, 29 distal, 26 Whipple, 3<br />

others). Eighty-four (31%) of those patients had vascular involvement (Vi): Splenic vein thrombosis<br />

(SVT; 15), SVT with left-sided portal hypertension (29), generalized portal hypertension<br />

due to portal vein thrombosis or compression (22), regional portal hypertension without SVT<br />

(12) or arterial collaterals (6). Forty-two of the patients had concomitant splenectomy during<br />

surgery.<br />

Results: In the patients with Vi median duration of surgery (420 min vs. 392 mins) and volume<br />

of transfused blood (1200 ml vs. 600 ml) were higher than in patients without Vi. Mortality<br />

was 2/84 in the Vi-group vs. 1/189 in patients without Vi (n.s.). The reoperation rate was 14%<br />

(Vi) vs. 5% (no Vi; p
