可控负压吸引取石器在保胆取石术中的应用效果研究

摘要

目的：探讨可控负压吸引取石器在保胆取石术患者中的应用效果。方法：选取2013年3月-2015年3月在本院行保胆取石术的胆囊结石患者250例，将其随机分为试验组127例和对照组123例。试验组在腹腔镜下联合胆道镜及自制可控负压吸引取石器对胆囊结石患者进行保胆取石术，对照组采取腹腔镜下联合胆道镜对胆囊结石患者进行保胆取石术。对比两组住院费用、手术时间、术中出血量、术后排气时间、住院天数、术后1周结石残留率及术后1、3、6、12个月的结石复发率。结果：两组术后均恢复良好，无严重并发症发生。两组住院费用、住院天数、手术时间、术后排气时间比较差异均有统计学意义（P<0.05）。对照组术后1周复查B超发现结石残留4例，残留率为3.25%，1年内复发共计14例（11.38%）；试验组术后1周复发为0，1年内复发共计2例（1.57%），两组比较差异均有统计学意义（P<0.05）。结论：可控负压吸引取石器治疗胆囊结石方法简单，方便易行，治疗效果好，值得临床推广。%Objective:To investigate the efficacy of controllable negative pressure suction device in cholecystolithotomy.Method: A total of 250 patients with cholecystolithiasis undergoing cholecystolithotomy in our hospital from March 2013 to March 2015 were selected,they were randomly divided into experimental group of 127 cases and control group of 123 cases.The experimental group received laparoscope combined with choledochoscope-guided cholecystolithotomy and a self-made controllable negative pressure suction device.The control group underwent cholecystolithotomy guided by laparoscope combined with choledochoscope.Hospitalization expenses, the duration of surgery, intraoperative bleeding,postoperative diet recovery time, postoperative hospital stay, residual stone rate 1 week after surgery, and stone recurrence rate 1,3,6 and 12 months after surgery in both groups were compared.Result:Both groups recovered well after surgery,and had no severe complications. Hospitalization expenses,postoperative hospital stay,the duration of surgery and postoperative diet recovery time showed significant differences between the two groups(P<0.05). After operation1 weeks, 4 cases of residual stones in control group,the residual rate was 3.25%,recurrence within 1 years a total of 14 cases (11.38%);the experimental group after 1 weeks of recurrence was 0,recurrence within 1 years a total of 2 cases (1.57%),the differences were statistically significant(P<0.05).Conclusion:Application of the controllable negative pressure suction device in the treatment of cholecystolithiasis is characterized by simple method, easy operation and good efficacy,thus it is worthy of clinical promotion.
