Utility of Retroperitoneal Laparoscopic Surgery for Retroperitoneal Tumors.

INTRODUCTION

Retroperitoneal laparoscopic surgery for benign retroperitoneal tumors is often challenging because of variations in the tumor location and size. In this study, we present a retroperitoneal laparoscopic resection technique used at our institution to treat benign retroperitoneal tumors.

MATERIALS AND METHODS

This retrospective case series included nine consecutive patients who underwent retroperitoneal laparoscopic tumor resection between 2011 and 2023. We analyzed patients' clinical characteristics and perioperative outcomes.

RESULTS

There were four women and five men with a median age of 44 (range, 15-70) years and a median body mass index of 22.0 (range, 17.8-29.2) kg/m. Among the nine tumors resected, 7 were located in the right suprahilar region, 1 in the left suprahilar region, and 1 in the left infrahilar region. The median maximal tumor diameter was 3.0 cm (range, 1.8-12). The median operative time and estimated blood loss were 144 minutes (range, 76-358) and 7 mL (range, 1-479), respectively. No major perioperative complications (Clavien-Dindo grade ≥3) or conversion to open surgery were recorded. Pathological examination confirmed negative surgical margins in all cases.

CONCLUSIONS

Retroperitoneal laparoscopic resection was found to be a feasible and safe approach for treating benign retroperitoneal tumors.
