ABSTRACT
Background
Cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) are complex surgeries with multiple comorbidities. The Clavien–Dindo classification (CDC) is the most commonly used method to report surgical morbidity, but limits it to the highest-grade complication. The Comprehensive Complication Index (CCI) is a score ranging from 0 to 100, calculated using all 30-day complications and their treatment after abdominal surgery. The aim of this study is to assess the CCI’s validity in the HIPEC patient population.
Methods
A review of our institutional cytoreduction database from 2009 to 2015 was undertaken. Patient demographics, pathology, Peritoneal Carcinomatosis Index (PCI), complications and their treatments, and length of stay (LOS) were reviewed. The CCI was calculated for each patient. Linear regression was used to assess whether the CCI and CDC were predictors of LOS.
Results
Of 157 patients reviewed, 110 (70.1%) underwent HIPEC. The majority were female (77, 66.9%), and the mean age was 53.7 years. Mean PCI was 13.2 [interquartile range (IQR) 7–18]. Median CDC was grade 2 (IQR 0–2), and only 9.8% had CDC of grade 4 or higher. Mean CCI was 21.4, while the median was 20.9 (IQR 0–30.8). Mean LOS was 16.2 days, while the median was 11 days (IQR 8–15 days). The CCI strongly correlated with LOS with coefficient of 0.46 [95% confidence interval (CI) 0.38–0.54, p = 0.000].
Conclusions
The CCI is an adequate tool to capture all complications and their overall burden in patients having undergone HIPEC. This study shows that the CCI can predict LOS and could be used to quantify and compare the burden of multiple complications.
