摘要
目的探讨腹腔镜下全腹膜外修补术(TEP)治疗腹股沟疝的学习曲线。方法收集该院2012年12月至2016年8月同一组医师行腹腔镜的腹股沟疝患者450例,按手术开展时间的先后顺序分为3组,每组150例。提取各组行TEP手术的患者相关信息,分为A、B、C 3组,比较各组术前、术中、术后各相应指标。结果 3组年龄、性别,术前阴囊疝、复发疝与双侧疝发生率,以及疝类型比较,差异均无统计学意义(P>0.05)。3组术后尿潴留、术后镇痛、血清肿发生率及住院费用比较,差异均无统计学意义(P>0.05)。3组术中中转率、手术时间、术中出血量比较,差异均有统计学意义(P<0.05);且A组与B组上述3项指标比较,差异均有统计学意义(P<0.05),B组与C组比较差异均无统计学意义(P>0.05)。以术中出血、手术时间和手术例数作回归曲线,可见约150例有拐点。结论腹股沟疝腹腔镜下TEP的学习曲线约为150例腹腔镜疝修补术经验(包含16例TEP),经过术前评估及合适的病例筛选,学习曲线内的TEP手术亦可以安全进行。
Objective To investigate the learning curve of laparoscopic totally extraperitoneal （TEP） inguinal hernia repair. Methods The clinical data of 450 cases of patients who received laparoscopic inguinal hernia repair by the same group of surgeons from December 2012 to August 2016 in our hospital were sequentially divided into three groups,with 150 cases in each group. The cases of each group who received TEP inguinal hernia repair were extracted and enrolled into group A,B and C. The preoperative, intraoperative and postoperative indicators were compared among the three groups. Results Before operation,no statistically signif- icant difference was found in age, gender,incidence rates of scrotum hernia, recurrent hernia and bilateral hernia,and types of hernia among the three groups （P〉0.05）. And there was no statistically significant difference in incidence rates of postoperative urinary retention, analgesia and seromas, and hospitalization expenses among the three groups （P〈0.05）. During operation, differences in conversion rate,operative time and volume of blood loss among the three groups were statistically significant （P〈0.05）. Moreover, statistically significant differences in conversion rate, operative time and volume of blood loss were found between group A and group 13 （P〈0.05） ,while there was no statistically significant difference between group B and group C （P〉0.05）. The regression curves were drawn based on operation time,volume of blood loss and the number of cases,which estimated the inflection point was 150. Conclusion The learning curve of TEP inguinal hernia repair include approximately 150 cases of laparoscopic inguinal hernia repair （including 16 cases of patients received TEP）. The TEP inguinal hernia repair operation during the learning curve can be safety on the basis of preoperative evaluation and appropriate case selection.
