Résumé
OBJECTIVE: To report the postoperative outcome of hepatectomy associated with portal vein resection (PVR) and to identify risk factors of clinical value for predicting postoperative liver failure and mortality. SUMMARY BACKGROUND DATA: Resection of the portal vein during hepatectomy allows an increase in the number of patients 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 liver failure and mortality after such extensive operations. METHODS: Between July 1996 and July 2008, a total of 1348 patients were operated on for liver disease in our institution. Among them, 55 patients underwent liver resection associated with PVR. Medical records of these patients were prospectively collected and retrospectively analyzed. RESULTS: Overall mortality for this selected group of patients was 7.2%. Irreversible liver failure was the main cause of death. Overall morbidity was 58.1%. A total of 94% of the patients (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 postoperative liver failure. Male gender was the single independent risk factor for liver failure. Moreover, the presence of liver steatosis (P = 0.014), an extended right hepatectomy procedure (P = 0.047), and postoperative liver failure (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 PVR can be performed with acceptable overall morbidity and mortality rates. Preoperative selection of the patients should take in consideration the gender and the extent of hepatic resection to avoid irreversible postoperative liver failure. Extended right hepatectomy with PVR should be carefully considered in patients with liver steatosis due to the high risk of postoperative mortality.
