Lessons from the Initial Experience of Laparoscopic Liver Resection

Purpose: This study was conducted to evaluate the initial experience of 24 cases of laparoscopic liver resection by a single surgeon to determine its feasibility and report perioperative complications associated with this technique. Methods: A retrospective analysis of data from 24 patients who received attempted laparoscopic liver resections for primary liver tumors from November 2008 to April 2012 was conducted. Sixteen benign and eight primary malignant lesions were included. The patient’s electronic medical records including age, gender, underlying disease, past medical history, type of operations, operative time, complications, conversion rates, and length of hospital stay were reviewed. Results: The mean age of the patients was 52.6 years and the mean operation time was 263.7 minutes. The overall morbidity was 12.5% and the mortality was zero. One case was converted to open surgery (4.2%), while intraoperative transfusion was conducted in four cases. The types of operations included left hepatectomy (n=12, 50%; 3 with CBD exploration), left lateral sectionecectomy (n=4, 16.7%; 1 with cholecystectomy), partial hepatectomy for benign tumor (n=3, 12.5%: 1 with cholecystectomy), right hepatectomy (n=1, 4.1%), S6 segmentectomy (n=1, 4.1%), and tumorectomy (n=3, 12.5%). The mean estimated blood loss during operation was 375.3 cc and the postoperative hospital stay was 7.7 days. Additionally, one intraoperative complication and two postoperative complications occurred (12.5%). There was no postoperative mortality. Conclusion: The results of this study indicate that laparoscopic surgery with HBP training is suitable for laparoscopic liver resection. However, to ensure safety of the liver resection and the advantages of laparoscopic surgery, a thorough understanding of hepatic anatomy and elaborate surgical planning is essential.
