Cytoreductive Surgery and Intraperitoneal Hyperthermic Chemotherapy (HIPEC) by Minimally Invasive Approach, an Initial Experience.

Abstract

The cytoreductive surgery (CRS) associated with hyperthermic intraperitoneal chemotherapy (HIPEC) has become the standard treatment in patients with carcinomatosis peritoneal from different origins. The use of a minimally invasive approach for this high complex procedure might be an alternative that provides them less morbidity and faster recovery with similar oncologic outcomes. We describe the initial experience of CRS and HIPEC done via the laparoscopic route in patients with minimal peritoneal metastases in our Unit from March 2016 to January 2018. A total of eight patients were operated by this minimally invasive approach. The different diagnoses were low-grade pseudomyxoma peritonei (2), benign multicystic mesothelioma (2), primary epithelial ovarian carcinomatosis (2) and locally advanced colon carcinoma T4 (2). The median age was 54 (20-62) years, the median PCI was 3 (2-4), the median operative time was 287min (240-360), complete cytoreduction CC0 was achieved in all the patients, and no major morbidity was observed. The median length of stay was 4.75days (4-5). After a median follow-up of 9.5months, no relapse has been observed. The results suggest that this minimally invasive approach for CRS and HIPEC is feasible and safe in a highly selected group of patients with peritoneal surface malignancies.
