Objective To summary the experience of transabdominal preperitoneal space tension-free repair for inguinal saddle hernia. Methods 〗The clinical data of 151 cases of inguinal saddle hernias underwent transabdominal preperitoneal space tension-free repair with Prolene hernia system (PHS) were retrospectively analyzed. The operative time, postoperative pain, hospital stay, recurrence and postoperative complications were observed. Results The average operative time in unilateral hernias was (29.8±9.6) min. Postoperative complications included one case of pain in groin and 4 cases of scrotum edema. No incision infection and mortality occurred. Postoperative duration of hospital stay was 3 to 5 days. All cases were followed up for 1-5 years and no recurrence happened. Conclusion 〗Transabdominal preperitoneal space tension-free repair for inguinal saddle hernia by PHS is safe and reliable.
