To explore the clinical effect of laparoscopic transabdominal preperitoneal repair (TAPP) in the treatment of inguinal hernia after radical prostatectomy, and to provide theoretical basis for optimizing the surgical treatment of inguinal hernia after radical prostatectomy.

A retrospective study was conducted on 68 patients with inguinal hernia and 215 patients with primary inguinal hernia after radical prostatectomy treated by TAPP in the Shanghai Ninth People's Hospital, School of Medicine, Shanghai Jiao Tong University from January 2016 to December 2020. According to the causes of inguinal hernia, the patients with inguinal hernia after radical prostatectomy were the experimental group, and the patients with primary inguinal hernia were the control group. The operation time, intraoperative blood loss, intraoperative complication rate, postoperative hospital stay, postoperative pain score, postoperative complication rate and postoperative recurrence of the two groups were analyzed and compared.

The surgical time of the experimental group was longer than that of the control group (P<0.05). There was no statistically significant difference (P>0.05) between the two groups of patients in terms of intraoperative bleeding volume, incidence of intraoperative complications, postoperative hospitalization days, postoperative pain score, incidence of postoperative complications, and postoperative recurrence.

TAPP is safe and effective in the treatment of inguinal hernia after radical prostatectomy. The efficacy of laparoscopic repair for inguinal hernia after radical prostatectomy is similar to that of patients with primary inguinal hernia.
