ABSTRACT
BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) has been identified as risk factor for several diseases; however, its association with post endoscopic retrograde cholangiopancreatography pancreatitis (PEP) has not been studied. AIMS: To assess whether NAFLD is a risk factor for the development of PEP. METHODS: We performed a retrospective multicenter study. All patients who underwent ERCP during 2013-2016 at either the Shaare Zedek Medical Center in Jerusalem or EMMS Nazareth hospital and who had a diagnosis of NAFLD by abdominal imaging were eligible for inclusion. Four hundred and one patients were included, among them, 38 (9.5%) were diagnosed with PEP according to clinical, laboratory and radiological criteria. RESULTS: In univariate analysis, the following risk factors were associated with increased risk for PEP; Fatty liver (OR 2.363, p = .01), elevated levels of aspartate transaminase (OR 1.008, p = .04), ALT (OR 0.979, p = .0007), alkaline phosphatase (OR 1.008, p = .01), gamma-glutamyl transferase (OR 1.014, p = .0005) and total bilirubin (OR 1.141, p = .005). In multivariate logistic regression analysis, only NAFLD showed statistically significant association with PEP (OR 3.224, 95% CI 1.548-6.713, p = .001) with receiver operator characteristics (ROC) area under the curve (AUC) of 0.8156. CONCLUSION: NAFLD was shown to be a risk factor for PEP. Therefore, we suggest considering prophylactic pancreatic stenting and/or NSAID's suppositories among these patients.

BACKGROUND: Treatment of cholangitis complicating choledocholithiasis includes biliary sphincterotomy and stone extraction. In certain cases of elderly comorbid patients with high risk for definitive endoscopic treatment, biliary stenting is the only measure for relieving biliary obstruction. AIM: We aimed to report the safety of retained biliary stone. METHODS: a multi-center, retrospective case-control study conducted at two Israeli medical centers from January 2013 to December 2018 including all patients 18 years of age or older who underwent ERCP and biliary stent insertion for the treatment of acute cholangitis due to choledocholithiasis. RESULTS: Three-hundred and eight patients were identified. Eighty-three patients had retained long-term biliary stents of more than 6 months (group A) from insertion compared to 225 patients whose biliary stents were removed within a 6-month period (group B). The mean follow-up in group A was 66.1± 16.3 vs. 11.1 ± 2.7 weeks in group B. Overall complications during the follow-up were similar between groups A and B (6% vs. 4.9%, OR 1.24, Chi square 0.69). Similarly, the rate of each complication alone was not different when comparing group A to group B (3.6%, 1.2% and 1.2% vs. 2.7%, 0.44% and 1.8%) for cholangitis, stent related pancreatitis and biliary colic, respectively (Chi square 0.85). Even after 12 months, the rates of overall complications and each complication alone were not higher compared to less than 12 months (Chi square 0.72 and 0.8, respectively). CONCLUSION: endoscopic biliary stenting for cholangitis complicating choledocholithiasis is safe for the long-term period without increase in stent related complications.
