An Asian Tertiary Centre's Early Experience with Laparoscopic Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Carcinomatosis.

Abstract

The use of open cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has shown improved oncological survival in terms of treating peritoneal surface malignancies (PSM). However, this procedure often comes with associated morbidity. The move towards use of laparoscopic surgery in this field is postulated to lead to a reduction in morbidity and earlier return to function, but literature on its use for CRS and HIPEC has been scarce. We performed a retrospective review of 6 patients with PSM who underwent laparoscopic CRS and HIPEC in our institution and analysed the patient characteristics, oncological history, perioperative and postoperative outcomes. Median peritoneal cancer index (PCI) score was 0 (IQR 0-1.25). All 6 patients had appendiceal primaries. Median operative time was 285min (IQR 228.8-300); median length of stay was 7.5days (IQR 5-8.8). All patients achieved complete cytoreduction, and there was no conversion to open surgery. One patient developed port site infection and another 2 patients subsequently developed adhesions. Median follow-up time was 35 (IQR 17.5-41) months. No patients had developed recurrence at the time of data collection. We conclude that in patients with limited PCI sore (< 2), laparoscopic CRS and HIPEC are safe and feasible. With increasing experience, a select group of patients with limited PSM may be treated via minimally invasive surgery, minimising the morbidity of a traditional laparotomy.
