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.
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.
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.
Retroperitoneal laparoscopic resection was found to be a feasible and safe approach for treating benign retroperitoneal tumors.
由于腹膜后良性肿瘤的位置和大小存在差异，腹膜后腹腔镜手术治疗此类肿瘤往往具有挑战性。在本研究中，我们介绍了我院用于治疗腹膜后良性肿瘤的一种腹膜后腹腔镜切除术技术。
本回顾性病例系列研究纳入了2011年至2023年间连续接受腹膜后腹腔镜肿瘤切除术的9例患者。我们分析了患者的临床特征和围手术期结局。
9例患者中，女性4例，男性5例，中位年龄44岁（范围15 - 70岁），中位体重指数22.0（范围17.8 - 29.2）kg/m²。在切除的9个肿瘤中，7个位于右上极区域，1个位于左上极区域，1个位于左下极区域。肿瘤最大直径的中位数为3.0 cm（范围1.8 - 12 cm）。手术时间中位数和估计失血量分别为144分钟（范围76 - 358分钟）和7 mL（范围1 - 479 mL）。未记录到围手术期严重并发症（Clavien-Dindo分级≥3级）或转为开放手术的情况。病理检查证实所有病例手术切缘均为阴性。
腹膜后腹腔镜切除术是治疗腹膜后良性肿瘤的一种可行且安全的方法。
