OBJECTIVE: To report the postoperative outcome of hepatectomy associated with @entity6315 ( @entity6315 ) and to identify risk factors of clinical value for predicting @entity1578 and mortality. SUMMARY BACKGROUND DATA: Resection of the portal vein during hepatectomy allows an increase in the number of @entity1 who may benefit from a potentially curative operation that is, however, technically difficult and may increase postoperative morbidity and mortality. Few data are available about risk factors for @entity1578 and mortality after such extensive operations. METHODS: Between July 1996 and July 2008, a total of 1348 @entity1 were operated on for @entity409 in our institution. Among them, 55 @entity1 underwent liver resection associated with @entity6315 . Medical records of these @entity1 were prospectively collected and retrospectively analyzed. RESULTS: Overall mortality for this selected group of @entity1 was 7.2%. Irreversible @entity1578 was the main cause of @entity204 . Overall morbidity was 58.1%. A total of 94% of the @entity1 (n = 52) underwent a major (>=  3 segments) or an extended > 4 segments) right or left hepatectomy. Univariate analysis showed that male gender (P = 0.004), extended liver resection (P = 0.028), and, particularly, extended right hepatectomy (P = 0.015) were significantly associated with an increased risk of @entity1578 . Male gender was the single independent risk factor for @entity1578 . Moreover, the presence of @entity1560 (P = 0.014), an extended right hepatectomy procedure (P = 0.047), and @entity1578 (P = 0.046) were significantly associated with an increased rate of postoperative mortality. CONCLUSION: The present study confirmed that major or extended hepatic resection with @entity6315 can be performed with acceptable overall morbidity and mortality rates. Preoperative selection of the @entity1 should take in consideration the gender and the extent of hepatic resection to avoid irreversible @entity1578 . Extended right hepatectomy with @entity6315 should be carefully considered in @entity1 with @entity1560 due to the high risk of postoperative mortality.
