1Resection of pancreatic cystic neoplasms in recurrent acute pancreatitis prevents recurrent pancreatitis but does not identify more malignancies显示文摘BACKGROUND Recurrent acute pancreatitis(RAP)may be a presenting feature of and an indication for resection of pancreatic cysts,including intra-ductal papillary mucinous neoplasm(IPMN).Few data are available regarding the prevalence of malignancy and post-operative RAP in this population.AIM To study the role of resection to help prevent RAP and analyze if presentation as RAP would be a predictor for malignancy.METHODS This retrospective study assessed 172 patients who underwent surgical resection of pancreatic cystic neoplasms at a university hospital between 2002 and 2016.The prevalence of preoperative high-risk cyst features,and of neoplasia was compared between patients with and without RAP.To identify the cause of pancreatitis,all the patients had a detailed history of alcohol,smoking,medications obtained,and had cross-sectional imaging(contrast-enhanced computed tomography/magnetic resonance imaging)and endoscopic ultrasound to look for gallstone etiology and other structural causes for pancreatitis.The incidence of RAP post-resection was the primary outcome.RESULTS IPMN accounted for 101 cases(58.7%){[branch duct(BD)59(34.3%),main duct(MD)42](24.4%)}.Twenty-nine(16.9%)presented with RAP(mean 2.2 episodes):15 had BD-IPMN,8 MD-IPMN,5 mucinous cystic neoplasm and 1 serous cystic neoplasm.Malignancy was similar among those with vs without RAP for all patients[6/29(20.7%)vs 24/143(16.8%)]and IPMN patients[6/23(26.1%)vs 23/78(29.5%)],although tended to be higher with RAP in BD-IPMN,[5/15(33.3%)vs 3/44(6.8%),P=0.04].At mean follow-up of 7.2 years,1(3.4%)RAP patient had post-resection RAP.The mean episodes of acute pancreatitis before vs after surgery were 3.4 vs 0.02(P<0.0001).CONCLUSION Malignancy was not increased in patients with pancreatic cystic neoplasms who have RAP compared to those without RAP.In addition,specific cyst characteristics were not clearly associated with RAP.The incidence of RAP was markedly decreased in almost all patients following cyst resection.Thiruvengadam Muniraj Harry R Aslanian Loren Laine Priya A Jamidar James F Farrell Kisha A Mitchell Ronald R Salem 2021World Journal of Gastroenterology2021,27,15:3
