RESUMEN
OBJECTIVE: We aimed to investigate the prevalence of vascular complications in acute pancreatitis (AP), to compare patient outcomes using various treatments, and to explore the related risk factors. METHODS: Consecutive AP patients admitted from January 2010 to July 2017 were retrospectively included. Demographics, vascular complications, laboratory indices, and imaging findings were collected. Univariate and multivariate analyses were used to explore potential risk factors of vascular complications. RESULTS: Of 3048 AP patients, 808 (26.5%) had vascular complications, including visceral vein thrombosis, sinistral portal hypertension, and arterial complications. And 38 (4.7%) patients received anticoagulant therapy and had a higher rate of recanalization (P < 0.001). Bleeding occurred in 95 (11.8%) patients, who received further treatment. Multivariate analysis identified male gender (odds ratio [OR] 1.650, 95% confidence interval [CI] 1.101-2.472), hyperlipidemia (OR 1.714, 95% CI 1.356-2.165), disease recurrence (OR 3.727, 95% CI 2.713-5.118), smoking (OR 1.519, 95% CI 1.011-2.283), hemoglobin level (OR 0.987, 95% CI 0.981-0.993), white blood cell (WBC) count (OR 1.094, 95% CI 1.068-1.122), non-vascular local complications (OR 3.018, 95% CI 1.992-4.573), computed tomography severity index (CTSI) (OR 1.425, 95% CI 1.273-1.596), and acute physiology and chronic health evaluation (APACHE) II score (OR 1.057, 95% CI 1.025-1.090) were related to vascular complications. CONCLUSIONS: Vascular complications in AP is prevalent and their treatment is challenging. Further investigations are warranted to determine the optimal treatment strategy. Independent risk factors included male gender, hyperlipidemia, disease recurrence, smoking, WBC count, non-vascular local complications, CTSI, and APACHE II score.

OBJECTIVE: This study aimed to determine the risk factors and establish a risk score for post-transjugular intrahepatic portosystemic shunt (TIPS) overt hepatic encephalopathy (OHE). METHODS: Altogether 299 and 62 cirrhotic patients receiving TIPS from January 2015 to March 2018 were divided into the derivation and validation cohorts, respectively. The data of the derivation cohort were analyzed for risk factors of post-TIPS OHE. A risk score was established from the derivation cohort and verified by the validation cohort. RESULTS: During a median follow-up of 112.6 weeks, 52 (17.4%) patients in the derivation cohort experienced post-TIPS OHE. Logistic regression showed that alcoholic cirrhosis (odds ratio [OR] 3.068, 95% confidence interval [CI] 1.423-6.613, P = 0.004), stent diameter of 10 mm (OR 12.046 [95% CI 2.308-62.862], P = 0.003), portal pressure gradient (PPG) decrement ≥60% (OR 3.548 [95% CI 1.741-7.230], P < 0.001), model for end-stage liver disease (MELD) score ≥10 (OR 2.695 [95% CI 1.203-6.035], P = 0.016), blood ammonia (OR 1.009 [95% CI 1.000-1.018], P = 0.043) and notable hydrothorax (OR 4.393 [95% CI 1.554-12.415], P = 0.005) were associated with an increased risk of post-TIPS OHE. The risk score reached a promising risk evaluation of post-TIPS OHE when verified by the validation cohort (sensitivity 71.4%, specificity 70.7%, accuracy 71.0%). CONCLUSIONS: Alcoholic cirrhosis and notable hydrothorax are independent risk factors for post-TIPS OHE in liver cirrhosis, together with the stent diameter of 10 mm, PPG decrement ≥60%, MELD score ≥10 and blood ammonia. The established risk score is reliable to identify high-risk individuals of developing post-TIPS OHE.
