A Comparison of Laparoscopic Surgery and Open Surgery in Liver Resections: A Single-Center Experience.

Objective: With the developments in patient management and the increase in surgical experience, the use of laparoscopy in liver resections has become widespread. However, with the consensus meetings and international recommendations, laparoscopic liver resections have been tried to be standardized. We aimed to present this laparoscopic liver resection experience by comparing open and laparoscopic techniques.

Materials and methods: Patients who underwent liver resections between 2015 and 2022 were retrospectively screened and divided into 2 groups as laparoscopic liver resections and patients who underwent liver resection with open surgery. Indications, resection techniques, operative times, length of hospital stay, early hospital mortality, and complications were compared between both groups using statistical methods.

Results: Laparoscopic surgery was performed in 31 (14%) patients, and open surgery was performed in 189 (86%). The mean operation time was 316 ± 168.2 minutes in patients who underwent laparoscopic liver resection. It was 329.4 ± 123.6 in the open surgery group. The length of hospital stay was 11.6 ± 4.9 days in patients who underwent laparoscopic liver resection, while it was 19.7 ± 12.1 days in patients who underwent open surgery. The difference between the length of hospital stay was statistically significant (Mann-Whitney U-test, P=.00). There was no difference between the 2 groups in terms of complications and early mortality.

Conclusion: Laparoscopic liver resections are a safe method that can be applied in 3 or less segment resections. As the experience of the surgical team increases, it can be safely applied for major hepatectomies.
