Ultra-micro instrument in laparoscopic transabdominal preperitoneal (TAPP) hernioplasty.

This study aimed to explore the feasibility of ultra-micro instruments in the laparoscopic repair of inguinal indirect hernia. This retrospective study included 83 patients with an indirect inguinal hernia who underwent elective surgery from January 2020 to December 2021. All patients were divided into the traditional laparoscopic group and ultra-micro laparoscopic group. The data on operation time, blood loss, ventilation time, hospital stays, complication, postoperative pain degree was collected and compared between the two groups. Of these 83 patients, 25 assigned to the ultra-micro group used ultra-micro instruments while 58 were assigned to the traditional group. The traditional group had a lower mean operation time (57.07 min) than the ultra-micro group (69.60 min) p < 0.05, while ultra-micro group patients had a shorter hospital stay (2 days) than the traditional group (3 days) p < 0.05. The ultra-micro group experienced significantly less pain for 6 h, 1 day, and 2 days postoperatively (2, 1, 0 points) compared to the traditional group (4, 2, 1 points) p < 0.05. There was no significant difference in blood loss, ventilation time, or complication between the two groups. Using ultra-micro instruments is safe and feasible. Patients have less postoperative pain and a smaller incision than the traditional laparoscopic instrument. It is worthy of clinical promotion.
