Compared with open surgery, it provides a reduced hospital stay, less intraoperative blood loss, less trauma, and fewer incisional infections, without affecting tumor outcomes. However, lesions in the right lobe of the liver are deep and obstructed by the ribs, making exposure difficult and increasing the degree of surgical difficulty; thus, liver tumors in the deep right lobe pose technical challenges in standard laparoscopic surgery.  \nAIM  \nTo investigate the safety and efficacy of laparoscopic retroperitoneal partial hepatectomy for liver tumors.  \nMETHODS  \nThe clinical data of 72 patients who underwent laparoscopic retroperitoneal partial hepatectomy for liver tumors between January 2018 and December 2024 atthe First People’s Hospital of Yunnan Province were analyzed. Of the 72 patients included, 34 were male and 38 were female, with ages ranging from 34 years to 72 years (median age, 45 years) . The tumors were all located in the right lobe of the liver, with 30 cases in segment S6, 27 cases in segment S7, and 15 cases in segment S8; the mean tumor diameter was 7.5 ± 3.4 cm. The postoperative tumor indices, liver function, and postoperative complications were analyzed to evaluate the clinical efficacy of laparoscopic partial hepatectomy via the retroperitoneal approach.  \n WJH  [https://www.wjgnet.com](https://www.wjgnet.com) 1 December 27, 2025  Volume 17  Issue 12   \nFei ZH et al. Partial hepatectomy via the retroperitoneal approach  \nRESULTS  \nThe surgeries were successfully completed in all patients, and conversion to open surgery was required in 10 patients. The mean operative time, blood loss, drain retention time, and length of postoperative hospital stay were 140 ± 30 minutes, 150 ± 46 mL, 3.8 ± 1.2 days, and 8.3 ± 5.3 days, respectively. Liver function tests returned to normal in all patients within two weeks of surgery.
