评价基底膜生物疝修补补片重建后腹膜和盆底、隔离腹盆腔，用于防治盆腔廓清术（PE）后空盆腔综合征的有效性和安全性。

收集2022年11月16日至2024年3月27日在海军军医大学第二附属医院肛肠外科接受PE并使用基底膜生物疝修补补片进行后腹膜和盆底重建的31例患者资料。采用回顾性描述性研究方法分析术后90 d内空盆腔综合征相关并发症（包括小肠梗阻、盆腔深部持续积液、盆腔感染形成脓肿或窦道）的总发生率、肠功能恢复时间、空盆腔综合征痊愈时间及Clavien-Dindo分级≥Ⅲ级的并发症发生情况。

31例患者中，术后90 d内空盆腔综合征相关并发症的总发生率为3.2%（1/31），该例为小肠梗阻。术后90 d内，死亡3例（死于肺栓塞1例，肿瘤转移、疾病进展2例），其余病例空盆腔综合征痊愈时间为（17.9±10.4）d，肠功能恢复时间为（7.7±5.6）d。

在PE中应用基底膜生物疝修补补片重建后腹膜和盆底、隔离腹盆腔是安全和有效的，术后90 d内空盆腔综合征相关并发症的发生率较低。

To evaluate the efficacy and safety of using a basement membrane biological hernia repair mesh for retroperitoneal and pelvic floor reconstruction and abdominopelvic isolation in preventing and managing post-pelvic exenteration (PE) empty pelvic syndrome.

Data were collected from 31 patients who underwent PE with retroperitoneal and pelvic floor reconstruction using a basement membrane biological hernia repair mesh at the Department of Anorectal Surgery, the Second Affiliated Hospital of Naval Medical University, between November 16, 2022, and March 27, 2024. A retrospective descriptive study was conducted to analyze the overall incidence of complications related to empty pelvic syndrome within 90 days after surgery (including small bowel obstruction, persistent deep pelvic effusion, pelvic infection with abscess or sinus tract formation), time to recovery of bowel function, time to resolution of empty pelvic syndrome, and the incidence of complications classified as Clavien-Dindo grade≥III.

Among the 31 patients, the overall incidence of complications related to empty pelvic syndrome within 90 days postoperatively was 3.2% (1/31). This single case was small bowel obstruction. Within 90 days after surgery, 3 patients died (1 died of pulmonary embolism; 2 died of tumor metastasis and disease progression). For the remaining cases, the recovery time of empty pelvic syndrome was (17.9±10.4) days, and the intestinal function recovery time was (7.7±5.6) days.

The application of a basement membrane biological hernia repair mesh in PE for retroperitoneal and pelvic floor reconstruction, as well as for isolating the abdominal and pelvic cavities, is safe and effective. The incidence of complications related to empty pelvic syndrome within 90 days after surgery is low.
