HEPATECTOMIES: INDICATIONS AND RESULTS FROM A REFERENCE HOSPITAL IN THE BRAZILIAN AMAZON.

Abstract

Background: Hepatectomy is historically associated with higher morbidity and mortality, related to intraoperative blood loss and biliary fistulas. Technological advances and improvements in surgical and anesthetic techniques have led to greater safety in performing these surgeries.

Aims: The aim of this study was to analyze morbidity and mortality in patients undergoing hepatectomy.

Methods: Retrospective cohort study of patients undergoing liver resections. The type of hepatectomy, indications, need for intraoperative blood transfusion, hospital stay, complications, and postoperative mortality were analyzed.

Results: A total of 48 hepatectomies were performed during the studied period, the most common being 26 (54.16%) major hepatectomies, distributed among 13 (50%) left hepatectomies, 11 (42.30%) right hepatectomies, and 2 (7.70%) others. In total, 24 (45.84%) minor hepatectomies were performed, 11 (50%) mono segmentectomies, and 5 (22.72%) left lateral hepatectomies. The main indications for resection in benign diseases were 6 (12.50%) neotropical hepatic hydatidosis, five (10.41%) intrahepatic lithiasis, and in primary malignancies, 9 (18.75%) hepatocarcinomas. There was no need for an intraoperative blood transfusion. Hospital stays after surgery ranged from 2 to 40 days (average=7 days), and 41 (85.42%) patients went to the ICU in the first 72 h after surgery. In total, 9 (18.75%) patients developed postoperative complications. Overall mortality was 2.08%.

Conclusions: Hepatocellular carcinoma and neotropical hydatidosis were the main diseases with surgical indication, and major hepatectomies were the most performed procedures. Morbidity and mortality were in line with results from major global centers.
