The surgical treatment of female primary pelvic retroperitoneal tumours: A retrospective study of 99 patients from a single centre in China.

Abstract

To summarise the application of minimally invasive surgery for female primary pelvic retroperitoneal tumours (PPRTs). The clinical data of PPRT in a hospital between January 2017 and August 2022 were retrospectively collected. Surgical outcomes for cystic and solid tumours and two minimally invasive techniques were compared. 99 patients were included. Cystic tumours had fewer intraoperative injuries (4.0% vs. 28.0%, p < 0.001) than solid tumours. Robot-assisted laparoscopy (RALS) seemed to have fewer intraoperative complications (8.3% vs. 35.1%, p=0.156) than conventional laparoscopy (CLS) in solid tumours. For cystic tumours, RALS included larger tumour sizes and longer operative times (p<0.05), but intraoperative injury was comparable to CLS. RALS exhibited a higher cost than CLS in all tumours. Minimally invasive surgery for solid PPRTs tends to be more difficult than for cystic tumours, and RALS has a slight advantage over CLS with respect to short-term PPRT outcomes.
