Abstract:
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 significant 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 B (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.
