The Oncologic Outcome of Laparoscopic Resection Malignant Liver
Hypothesis
Data from the literature indicate that laparoscopic liver resection surgery is receiving more attention and success rate as a treatment. It is hypothesized that nonrecurrence cases will outnumber the recurrent laparoscopic malignant liver cases.
Methodology
Out of 52 patients who had laparoscopic liver resection performed, 32 were identified with a malignant liver tumor. Their data were analyzed by studying each patient's follow up history, CT scan reports, pathology results and operative report to determine the disease-free survival rate and identify which patients had recurrence. The 32 underwent laparoscopic liver resection for malignant liver lesions between January 2006 and July 2009.
Outcomes
The findings of this study confirm many advantages of laparoscopic liver resection surgery, such as shorter hospital stay, less blood loss and a decreased risk of infections. Most importantly, there were no local recurrences in any of the patients who underwent laparoscopic liver surgery. The disease-free survival rate was 20.4 ± 1.8 months. The overall survival rate was 23.69 ± 1.12 months after the laparoscopic liver resection, confirming the success of the surgery. Moreover, 25 patients had no sign of recurrence after surgery.
