Clinical Comparison Study Of Conventional Open Surgery And Single-port Laparoscopic-assisted Testicular Fixation For Inguinal Canal Type Cryptorchidism

OBJECTIVE: This study focused on the advantages of single-port laparoscopicassisted orchiopexy(SLAO)for the treatment of children with inguinal canal cryptorchidism.METHODS: The case data of children with inguinal canal cryptorchidism admitted to our hospital from September 2019 to December 2022 were retrospectively analyzed.According to the surgical method,they were divided into traditional open surgery group(group A)and single-port laparoscopic-assisted testicular fixation group(group B),and the data on demographic data,preoperative and postoperative testicular position and size,intraoperative bleeding,postoperative hospital stay,postoperative efficacy and prognostic follow-up of children in groups A and B were compared.RESULTS: A total of 125 children with inguinal canal cryptorchid were included in this study,including 58 cases in group A and 67 cases in group B.The average age of the children was 48.5 months.55(44%)cases of right cryptorchidism,39(31.2%)cases of left cryptorchidism,and 31(24.8%)cases of bilateral cryptorchidism were included in this study,and the average postoperative follow-up time was 7.3 months.(P>0.05),and a statistically significant comparison between the two groups in terms of intraoperative testicular lead retention and finding of contralateral sphincter non-closure(P<0.05).In children with unilateral inguinal canal cryptorchidism,groups A and B had longer operative operating time in the former than in the latter(55.19 ± 1.93 h)than in the latter(42.43 ± 2.67 h),intraoperative bleeding(7.79 ± 0.64 ml)than in the latter(4.49 ± 0.51ml),incision length(20.63 ± 0.85 mm)than in the latter(5.10 ± 0.30 mm),incision scar score(1.34±0.48)compared to(0.71±0.46),and the differences were statistically significant(P<0.05).In children with bilateral inguinal canal cryptorchidism,groups A and B had longer surgical operation time in the former than in the latter(75.73±3.31h)compared to(63.44±4.49h),intraoperative bleeding(14.67±0.49ml)compared to(6.86±0.81ml),incision length(34.20±3.19mm)compared to(8.83±1.77mm),postoperative incision scar score(1.26±0.45)compared with(0.56±0.51),the differences were statistically significant(P<0.05).There was a statistically significant difference(P<0.05)between the two groups in the intraoperative preservation of the testicular lead and the finding of contralateral sphincter non-closure,and there was a statistically significant difference(P<0.05)in the occurrence of postoperative complications in group A(12.5%)than in group B(1.5%).Conclusion: Single-port laparoscopic-assisted testicular fixation for inguinal canal cryptorchidism has the advantages of less trauma,shorter operation time,fewer postoperative complications,more concealed incision and higher aesthetic appearance,and is worthy of clinical promotion.
