To investigate the application of arcuate line approach in single incision laparoscopic totally extraperitoneal inguinal hernia repair (SIL-TEP).

A retrospective analysis was conducted on the clinical data of 90 adult patients with unilateral or bilateral inguinal hernias who underwent SIL-TEP at Qichun Peoples' Hospital from March 2020 to February 2024. Among them, 52 patients underwent SIL-TEP by arcuate line approach (arcuate line approach group) and 38 patients underwent SIL-TEP by umbilicus approach (umbilicus approach group). Compare the surgical duration, chopstick effect duration, bleeding volume, pain score, bed rest time, and intraoperative and postoperative complications between the two groups.

All patients completed the surgery successfully, and there was no case of incision infection or recurrence. There was no statistical difference between the two groups in complications such as intraoperative blood loss, postoperative bed rest time, postoperative serum swelling (P>0.05); There were statistically significant differences between the two groups in terms of surgical time, the duration of chopstick effect (interference between instruments), the number of cases of peritoneal damage during surgery, and postoperative pain scores (P<0.05).

The SIL-TEP hernia repair surgery via the arcuate line approach is more convenient than the umbilicus approach, reducing surgical difficulty and making the operation approach safe and feasible.
