OBJECTIVE: The objective of this study was to investigate the short-term and long-term morbidity after liver transplantation (LTx) in patients with primary sclerosing cholangitis (PSC).
BACKGROUND: PSC is a common indication for LTx in Scandinavia. Recently, research has focused on long-term survival and morbidity. The Comprehensive Complication Index (CCI) precisely describes postsurgical complications, by considering both number and severity.
PATIENTS AND METHODS: Two patient groups were compared: those with classical PSC symptoms (n=148) and those with increased risk of cholangiocarcinoma (n=51, premalignant group). Two CCI scores were calculated, at 1-year post-LTx and a cumulative overall score at the latest follow-up. In addition, we investigated factors potentially related to high CCI.
RESULTS: The 1-year median CCI were 29.6 and 26.2 in the classical and premalignant groups, respectively ( P =0.308). The median overall CCI were 43.2 and 46.8 ( P =0.765), respectively. Patient survival was significantly lower in patients with 1-year CCI>42. The most common complications associated with low survival were cholangitis, infections, and hypertension. One-year and overall CCI were similar between sexes and different types of biliary anastomosis. Patients with pre-LTx Model for End-stage Liver Disease scores >20 had higher 1-year and overall CCI (36.2 and 52.6, respectively) than those with lower Model for End-stage Liver Disease scores. Both low (<22) and high (>25 kg/m 2 ) body mass indices were associated with high overall 1-year and overall CCI (50.9 and 41.8, respectively), but median body mass indices were associated with significantly lower 1-year and overall CCI (38.4, P =0.023).
CONCLUSIONS: The previously determined 1-year CCI cutoff of 42 could significantly predict survival post-LTx. Mortality and morbidity were not significantly different between the PSC groups analyzed.
