Abstract: Objective To explore the safety and feasibility of laparoscopic inguinal hernia day surgery in elderly patients（≥80 years old）.Methods Collect the clinical data of 235 elderly patients  who underwent laparoscopic inguinal hernia day surgery admitted to the Gastrointestinal Anorectal and Hernia Surgery Department of Nanchong Central Hospital from January 2020 to September 2023,and evaluate the curative effect of day surgery:operation time,intraoperative blood loss,hernia recurrence,incision infection,surgical area hematoma and effusion,urinary retention,chronic pain,and the incidence of mesh infection,spermatic cord and testicular complications,etc.All patients were followed up in the outpatient department and by phone on the day of discharge,and all patients were followed up after surgery for 3 days,1 month,and 3 months.Results All 235 elderly patients underwent laparoscopic inguinal hernia tension-free repair (TAPP/TEP) under general anesthesia,among which,80 patients used TAPP and 155 patients used TEP.The operation time of all patients was (35.0±6.0) minutes,the amount of intraoperative bleeding was (5.0±2.0) ml,there were 0 cases of postoperative delirium,0 cases of hernia recurrence,0 cases of incision infection,11 cases of surgical area hematoma and effusion,15 cases of urinary retention,8 cases of chronic pain,0 cases of mesh infection,and 0 cases of spermatic cord and testicular complications.Conclusion Laparoscopic inguinal hernia day surgery under general anesthesia in elderly patients（≥80 years old） is safe and feasible,with few perioperative complications,a high cure rate.
