The learning curve for totally extraperitoneal repair (TEP) is longer and steeper than that for transabdominal preperitoneal repair (TAPP) due to the preperitoneal view to which the surgeon is not accustomed and the limited working space. The aim of this study was to clarify the learning curve for SILS‐TEP. Methods A retrospective analysis of 80 consecutive patients with unilateral inguinal hernia was performed. All patients underwent elective SILS‐TEP performed by a single learning surgeon with a teaching assistant between July 2016 and March 2018 at Kinki Central Hospital. Results The operative time decreased gradually after 20 cases and stabilized after 40 cases. The first 40 cases were categorized as the learning period group, and the remaining 40 cases were categorized as the experienced period group. More patients received antithrombotic therapy in the experienced period than in the learning period ( P < 0.05). The median operative time was 107 and 60 min in the learning period and the experienced period, respectively ( P < 0.05). There were no significant differences in blood loss peritoneal injury, conversion to a different procedure, postoperative hospital stay, complications, and recurrence between the two groups. No major complications or hernia recurrence were noted during follow‐up. Conclusions The learning curve for SILS‐TEP might take 40 cases to reduce the operative time. SILS‐TEP can be performed safely by a learning surgeon with a teaching assistant.
