目的通过对复发性急性胰腺炎(RAP)患者CT表现及病因分析,探讨影响急性胰腺炎(AP)复发的病因,减少RAP发生。方法对42例RAP患者的CT表现及病因进行分析。结果 RAP主要病因为胆源性31例、高脂血症合并脂肪肝12例、酒精性7例。CT表现均见胰腺局部或弥漫性增大,边界模糊。16例可见小网膜囊积液混浊,肾前筋膜增厚;8例伴胰腺假性囊肿;伴胆石症14例、胆囊炎17例、胆管扩张6例。结论对于RAP患者,胰腺CT是诊断急性胰腺炎的金标准。积极彻底治疗胆道系统疾病,控制血脂水平、戒酒可降低RAP的复发。胆囊切除不能很好地防止AP的复发。
Objective To explore the etiopathogenesis of recurrent acute pancreatitis (RAP) in patients with recurrent acute pancreatitis (RAP) and to explore the etiopathogenisis of recurrent acute pancreatitis (AP) and reduce the occurrence of RAP. Methods 42 patients with RAP CT features and causes were analyzed. Results The main causes of RAP were biliary origin, hyperlipemia with fatty liver in 12 cases and alcohol in 7 cases. CT showed pancreatic local or diffuse increased, fuzzy boundaries. 16 cases showed cyst turbid opacity, prerenal fascia thickening; 8 cases with pancreatic pseudocyst; with cholelithiasis in 14 cases, cholecystitis in 17 cases, 6 cases of bile duct dilatation. Conclusion For patients with RAP, pancreatic CT is the gold standard for the diagnosis of acute pancreatitis. Active and thorough treatment of biliary system diseases, blood lipid levels, abstinence can reduce the recurrence of RAP. Cholecystectomy does not prevent AP recurrence well.
