To explore the advantages of laparoscopic totally extra-peritoneal hernia repair (TEP) in the treatment of inguinal hernia in primary hospital, and to draw the learning curve of TEP operation.

From January 2018 to June 2020, 85 inguinal hernia patients treated in Department of General Surgery, Zengcheng District People's Hospital of Guangzhou were selected. They were divided into two groups according to surgical methods. 40 patients were treated with TEP and 45 patients were treated with open hernia repair. The clinical effect and safety of two groups were observed. 40 patients who underwent TEP surgery were divided into group A, B, C and D according to the sequence, with 10 cases in each group. The operation conditions were compared.

TEP treatment of inguinal hernia is superior to open herniorrhaphy, which is characterized by low intraoperative blood loss, hospitalization time, recovery time and complications (P<0.05), but with high hospitalization cost and long operation time (P<0.05). The analysis of group A, B, C and D showed that after 20 cases of TEP operation, surgeon's technique gradually matured, and the intraoperative bleeding, hierarchical error and peritoneal rupture significantly reduced.

TEP operation can be selected for the clinical treatment of inguinal hernia in primary hospitals, with low complication rate and fast recovery. After completing 20 cases of TEP, beginners can significantly shorten the operation time and gradually master this technique.
