An 89-year-old man with polycystic liver disease (PCLD) received uncovered self-expandable metallic stent (SEMS) placement above the papilla for malignant biliary obstruction caused by cholangiocarcinoma. He developed cholangitis ten months later due to SEMS occlusion caused by tumor ingrowth, and 2 plastic biliary stents were placed inside the SEMS across the papilla. Fever and right costal pain appeared two weeks after reintervention. Suspecting hepatic cyst infection based on imaging studies, percutaneous transhepatic cyst drainage was performed. Increased inflammatory cells and the presence of pathogens in the cyst fluid led to a definitive diagnosis of hepatic cyst infection. Following drainage, the hepatic cyst shrank with resolution of the symptoms. SEMS occlusive-related cholangitis or retrograde infection due to duodenal-biliary reflux after reintervention was considered as the cause of the hepatic cyst infection. Careful clinical and imaging evaluation should be performed in patients with PCLD undergone biliary stenting, because cyst infection may occur following stent occlusion or subsequent biliary reintervention.

Management of early nutrition plays an important role in the treatment of acute pancreatitis patients, but the sample sizes of randomized control trials that have compared enteral and parental nutrition were small. From the data of Diagnostic Procedure Combination, we identified patients who had been diagnosed with acute pancreatitis and discharged from the hospital between 2014 and 2015. We compared the length of hospital stay and hospital mortality among patients with acute pancreatitis that was managed with and without enteral nutrition within 7 days from hospitalization. The results showed a significant decrease in the in-hospital mortality rate of 56% (odds ratio 0.444, 95% confidence interval [CI] 0.358 - 0.551, P
