Evaluation of Hepatic Resection Procedures for Benign and Malignant Focal Liver Lesions

Abstract

Background:Liver resection is the curative treatment for focal liver lesions. It is one of the high risk surgical procedures performed by experienced surgeons. 

Objective: To evaluate the different types of liver resections methods and associated factors related to morbidity and mortality in Gastroenterology Hospital and Baghdad Teaching Hospital.

Patients and Methods: This prospective study included 35 patients (age range 28-58 years, 15 male and 20 female) with focal liver lesions during the period from November, 2013 to February 2016. Fourteen patients were asymptomatic while the other patients were complaining form different symptoms. Preoperative assessment included liver and renal function tests, tumor markers and radiological investigations. Patients were followed up for one month for postoperative short-term complications.

Results: Bleeding was the most serious perioperative complication and all patients required blood transfusion. Eight hepatic resection methods were employed, and 8 types of lesions were detected, of which metastatic colorectal adenocarcinoma and cavernous hemangioma are the most prevalent (34.29% and 22.57% respectively). The duration of surgery ranged from 100 min in wedge resection to 300 min in different types of hepatectomy with average 8 days hospital stay. The most prevalent short-term complications were fever and atelectasis and wound infection (37.14% and 22.57% respectively).

Conclusion:Most evaluation criteria are comparable with that reported in global series, and accordingly, our center could perform different types liver resection.

Key words: Hepatic resection, focal liver lesions.
