BACKGROUND Cytoreductive surgery(CRS)with hyperthermic intraperitoneal chemotherapy(HIPEC)for peritoneal carcinomatosis can be performed in two ways:Open or closed abdominal *** To evaluate the impact of HIPEC method on post-operative and long-term survival *** Patients undergoing CRS with HIPEC from 2000-2017 were identified in the United States HIPEC collaborative ***-operative,recurrence,and overall survival outcomes were compared between those who received open vs closed *** Of the 1812 patients undergoing curative-intent CRS and HIPEC,372(21%)patients underwent open HIPEC and 1440(79%)underwent closed *** was no difference in re-operation or severe complications between the two *** HIPEC had higher rates of 90-d readmission while open HIPEC had a higher rate of 90-d *** multi-variable analysis,closed HIPEC technique was not a significant predictor for overall survival(hazards ratio:0.75,95%confidence interval:0.51-1.10,P=0.14)or recurrence-free survival(hazards ratio:1.39,95%confidence interval:1.00-1.93,P=0.05)in the entire *** findings remained consistent in the appendiceal and the colorectal *** In this multi-institutional analysis,the HIPEC method was not independently associated with relevant post-operative or long-term *** technique may be left to the discretion of the operating surgeon.
