目的：探讨老年胆结石合并胆道感染的临床分型及腹腔镜手术的选择时机。方法：收治老年胆结石合并胆道感染患者112例，分为轻症胆道感染组(A组)、先兆型急性重症胆道感染组(B组)和急性重症胆道感染组(C组)，采用腹腔镜胆囊切除术治疗。结果：①A、B、C三组构成比分别为49.11%、42.86%、8.04%，其中B组和C组胆囊+胆管结石发生率分别为39.58%、44.44%，高于 A 组的27.27%(P＜0.05)。②A、B、C 三组术后住院时间分别为(9.57±2.12)d、(16.95±3.12)d、(25.16±4.79)d，差异有统计学意义(P＜0.05)；③A、B、C三组术后残石率为5.45%、10.42%、33.33%(P＜0.05)；④A、B、C三组并发症发生率分别为1.82%、8.33%、33.33%(P＜0.05)。结论：胆囊并胆管结石患者容易发生急性胆道感染，轻症胆道感染、先兆型急性重型胆道感染者早期手术治疗效果较佳。“,”Objective:To explore the clinical classification of biliary tract infections in elderly patients with gallstones and timing of laparoscopic surgery.Methods:112 elderly patients with biliary tract infections and gallstones were selected.They were divided into the mild biliary tract infection group(A group),aura type acute severe biliary tract infection group(B group) and severe acute biliary tract infection group(C group),and patients were treated by laparoscopic cholecystectomy.Results:①The constituent ratios of the three groups of A group,B group and C group was 49.11%,42.86% and 8.04% respectively,and the incidence of gallbladder and bile duct stones of B group and C group was 39.58% and 44.44% respectively,higher than the A group of 27.27%(P<0.05).②Postoperative hospital stay of the three groups of A group,B group and C group was (9.57±2.12) days,(16.95±3.12) days and (25.16±4.79) days(P<0.05).③The postoperative residual stone rate of the three groups of A group,B group and C group was 5.45%,10.42% and 33.33%(P<0.05).④The incidence of complications of the three groups of A group,B group and C group was 1.82%,8.33% and 33.33% respectively(P<0.05).Conclusion:Patients with gallbladder and bile duct stones were prone to acute biliary infection.The effect of early surgical treatment for mild biliary tract infection and aura type acute severe biliary tract infection was better.
