Effects of ascites on outcomes of colorectal surgery in congestive heart failure patients.



There are limited data regarding the effects of ascites on outcome of patients undergoing colorectal resection. We sought to identify complications related to ascites.


The National Surgical Quality Improvement Program database was used to evaluate congestive heart failure (CHF) patients who had ascites before colorectal resection between 2005 and 2012. Multivariate regression analysis was performed to identify affected outcomes.


We sampled a total of 2,178 patients who suffered CHF and underwent colorectal resection, of which 195 (9%) had preoperative ascites. The mortality rate of patients who had preoperative ascites was 46.2% compared to 25.7% for patients without ascites (adjusted odd ratio [AOR], 3.38; P < .01). Complications affected by ascites include (P < .05) ventilator dependency (AOR, 2.40), acute renal failure (AOR, 2.18), and wound disruption (AOR, 2.44; P < .05). There was no increase in superficial surgical site infection rate in patients with ascites (AOR, 1.01; P = .9).


The presence of ascites in CHF patients is associated with increased mortality in patients undergoing colorectal surgery. There is no correlation between ascites and surgical site infection but wound disruption increases in the presence of ascites.
