[Comparison between hybrid surgery and transabdominal preperitoneal surgery in treatment of irreducible inguinal hernia: A case-control study].

To compare the effects between hybrid surgery and transabdominal preperitoneal surgery in treatment of irreducible inguinal hernia. A total of 60 patients who underwent laparoscopic inguinal hernia repair between June 2011 and December 2017 were included in the study. Patients were divided into two group: hybrid surgery group (observation group, 30) and transabdominal preperitoneal group (control group, 30). The operation time, intraoperative bleeding, hospital stay, hospital cost and complications were analyzed. The operative time of observation group and control group was 45 (35-65) minutes and 50(35-70) minutes, respectively. Intraoperative blood loss of two groups was 10(5-15) ml and 5(2-10) ml. The length of postoperative hospital stay was 2(1-4) days and 2(1-3) days in the two groups, respectively. And the hospitalization cost of two groups was 9 646 (9 066-11 560) yuan and 9 494(8 989-10 660) yuan, respectively. The intraoperative complications occurred in 4 cases in control group, including 1 case of vas deferens injury, 2 cases of spermatic vessel injury and 1 case of inferior epigastric artery injury. No intraoperative complications occurred in observation group. Perioperative complications in observation group and control group included dysuria (6.7% vs 10.0%), scrotum hematoma (3.4% vs 0%), wound pain (46.7% vs 6.7%) and fever (16.7% vs 20.0%). Twelve months of follow-up was completed in all the patients, and no recurrence or infections occurred in the two groups. The incidence of seroma in observation group and control group was 26.7%, 33.3%, respectively. One case of foreign body sensation and one case of chronic pain occurred in control group. The incidence of perioperative wound pain in patients undergoing hybrid surgery was higher than those undergoing transabdominal preperitoneal surgery (0.05), but no statistical differences were observed for other variables between the two groups (all 0.05). Hybrid surgery is safe and feasible for the treatment of irreducible inguinal hernia. Though with a higher incidence of postoperative acute pain, it may have advantages of avoiding injuries of the vas deferens and spermatic vessels.
