GUERRA C, JUAN FRANCISCO et al. Extended hepatectomy: A safe procedure for hepatobiliary malignancy. Rev Chil Cir [online]. 2007, vol.59, n.6, pp. 430-435. ISSN 0718-4026.

Introduction: Extended hepatectomy has been associated with a high perioperative risk. The aim of this study is to compare the surgical results in patients who underwent a hepatic resection of more than two Couinaud's segments versus an extended hepatectomy (more than four segments). Methods: Our prospective database from August 2002 to June 2005 was reviewed. Non-anatomical, unisegmental and laparoscopic resections were excluded. There were two groups. Group I: Extended hepatectomies; Group II: Hepatic resections from 2 to 4 segments. Demographic characteristics, indications for surgery, technical aspects, use of hemocomponents, post-operative liver function, morbidity and mortality were reviewed. Results: In this period, 59 hepatectomies were performed. 29 procedures achieved the inclusion criteria. Group I: (n=14), Group II: (n=15). Hepatobiliary malignancy was the surgical indication in all cases in Group I (9 liver metastases, 5 primary liver tumors). Mean number of resected segments were 5.5 for Group 1, and 2.3 for Group II. Mean operative time was 283 and 199 minutes, respectively (p=0.025). Mean red blood cell units transfused were 2.69 and 0.85 in each group (p=0.009). Mean postop hospital stay was 13.6 days por the first group and 7.3 for the second group (p=0.004). In Group I, 4 of 14 patients developed a postoperative complication and 1 of 15 in Group II (p=0.1). Postoperative liver failure was present in two patients from Group I, one of them died. In Group II, 1 patient died secondary to liver failure. Conclussions: Extended hepatectomy is a safe procedure for hepatobiliary malignancy even when a large amount of liver parenchyma is resected
