ABSTRACT
BACKGROUND: The aim of our study was to present the technique for, and early results of complete laparoscopic pelvic peritonectomy (LPP) plus hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: We conducted a study on consecutive patients who had LPP for limited peritoneal carcinomatosis (peritoneal carcinomatosis index < 10) from ovarian cancer, colon cancer and benign multicystic mesothelioma, from January 2017 to November 2019 at 2 referral centers in Spain. Perioperative, pathologic, 30-day major morbidity and mortality characteristics were analyzed. The surgical technique is shown in the attached video. RESULTS: Twelve LPP + HIPEC were performed. Complete cytoreduction was achieved in 100% of the patients, the median duration of the operation was 450 min (range 360-600 min). There were 2 cases (16%) of IIIa morbidity (trocar hernia and pleural effusion), and no mortality. The median length of hospital stay was 5.5 days (range 4-10 days). The median length of follow-up was 10 months (range 2-30 months). There was a recurrence at the splenic hilum in 1 patient which was treated by laparoscopic splenectomy and one nodal recurrence at 13 months while all other patients are alive and free of disease at last follow-up. CONCLUSIONS: This is the first technical video of a minimally invasive approach for complete pelvic peritonectomy plus omentectomy associated with HIPEC. For highly selected patients, this procedure presents a feasible and safe alternative to the maximally invasive approach.
