To summarize and analyze the application effect of laparoscopic totally extraperitoneal inguinal hernia repair via the affected side lateral space approach.

The clinical data of 30 cases of inguinal hernia repair using laparoscopic totally extraperitoneal approach through the lateral space of the affected side in the second Department of General Surgery, Northeast International Hospital from October 2020 to December 2020 were retrospectively analyzed, and the clinical effect was analyzed, and the surgical methods and significance were summarized and discussed.

All 30 cases were successfully operated, and the operation time was (42.64±12.05) min. During the operation, peritoneal rupture occurred in 5 cases, short-term incision pain after operation occurred in 1 case, seroma occurred in 2 cases after operation, and no complications such as incision infection, hematoma, chronic pain and mesh infection occurred. There was no recurrence after follow-up for 6 months.

Laparoscopic totally extraperitoneal hernia repair through the lateral space of the affected side is safe and feasible under the condition of mastering the operation skills. It observes the preperitoneal anatomy from a brand-new perspective and plays a positive role in correctly understanding the local anatomical structure in this area.
