Background: To retrospectively analyze the short-term outcomes between open hepatectomy (OH) and laparoscopic hepatectomy (LH) in the treatment of recurrent hepatocellular carcinoma (HCC). The objective is to develop the optimal surgical method for patients with recurrent liver cancer after operation.
Methods: We retrospectively reviewed the data of 165 HCC patients whose cancer recurred after hepatectomy between January 2015 and March 2021 at our medical center. According to the inclusion and exclusion criteria, a total of 74 patients were eventually enrolled in this study.
Results: Tumors located in S1, S7, or S8 and larger tumor diameters were more frequent in the OH group, and the difference was statistically significant. Furthermore, there were notable differences between the LH and OH groups in terms of intraoperative blood loss (140.00 vs. 348.68 mL, P<0.001), mean operation time (150.95 vs. 203.28 min, P=0.024), and mean postoperative hospital stay (6.76 vs. 11.28 days, P=0.014). There were no statistically significant differences in the remaining characteristics between the two groups. There was no significant difference in recurrence-free survival and overall survival between the two groups.
Conclusions: Compared with OH, LH can significantly reduce the amount of intraoperative blood loss and shorten the operation time and postoperative hospital stay. At the same time, laparoscopic surgery may be a better surgical approach for patients with tumors of smaller diameter located in segments 2 to 6.
