胰腺假性囊肿合并脓肿形成是急性胰腺炎患者死亡的重要原因之一。作者研究的目的是确定假囊肿经皮引流的治疗价值。对43例曾有急性胰腺炎病史并经超声或CT证实有直径大于5cm、持续存在6周以上的假囊肿患者行胰胆管造影(ERCP)以确定假囊肿与胰管间是否有交通,并在超声引导下经皮穿刺行假囊肿引流,测定囊肿液淀粉酶浓度。凡引流后7天内无复发者则认为治疗有效。根据假性囊肿内容物淀粉酶浓度和引流次数将病人分组,使用卡方检验进行统计分析。作者见到假囊肿液淀粉酶浓度低于或等于64温氏单位(WU)的19例患者中17例有效,而淀粉酶浓度高于64WU的24例
Pancreatic pseudocyst with abscess formation is one of the important causes of death in patients with acute pancreatitis. The purpose of the author’s study was to determine the therapeutic value of percutaneous drainage of false cysts. For 43 patients with a history of acute pancreatitis and confirmed by ultrasound or CT to have a cyst larger than 5 cm in diameter and persisting for more than 6 weeks, cholangiopancreatography (ERCP) was performed to determine whether there was traffic between the pseudocyst and the pancreatic duct. Ultrasound-guided percutaneous puncture drainage was performed to determine the amylase concentration in the cyst fluid. Those who did not have recurrence within 7 days after drainage were considered to be effective. The patients were grouped according to the amylase concentration and the number of drainage times of the pseudocyst contents, and statistical analysis was performed using the chi-square test. The authors found that 17 out of the 19 patients with a pseudo-cyst fluid amylase concentration lower than or equal to 64 Wenhe’s Units (WU) were effective, while 24 patients whose amylase concentration was higher than 64 WU
