First experience of junior surgeons with laparoscopic totally extraperitoneal herniorrhaphy: Comparison with experienced surgeons in a single institution.

BACKGROUND/OBJECTIVE: Laparoscopic totally extraperitoneal (TEP) herniorrhaphy is among the current leading inguinal hernia repair methods. This study aimed to investigate the safety and feasibility of a junior surgeon's first experience with laparoscopic TEP herniorrhaphy.

METHODS

A retrospective review was performed between January 2017 and December 2019 to analyze the medical records of patients with inguinal hernia who underwent laparoscopic TEP herniorrhaphy. The operative outcomes and complications of patients undergoing surgery by an experienced surgeon (group A, n = 100) were compared with those undergoing surgery by a junior surgeon (group B, n = 100).

RESULTS

The mean operative time for group B was significantly longer than that for group A (52.0 ± 15.1 min vs 60.1 ± 17.4 min; P = 0.03). A statistical difference was also found in the mean postoperative stay (1.1 ± 0.3 d vs 1.4 ± 0.7 d; P = 0.02) between the two groups. There were 2 and 3 cases of recurrence in these two groups respectively (P = 0.72). Considering the operating time as a variable of learning curve, significant stabilization can be achieved after 30 cases (67.3 ± 17.8 min vs 53.1 ± 11.1 min; P = 0.02).

CONCLUSIONS

The surgical outcomes of laparoscopic TEP herniorrhaphy performed by a well-trained junior surgeon were similar to the outcomes of an experience surgeon.
