ANALYSIS OF THE EFFICACY OF TRANSUMBILICAL SINGLE-SITE LAPAROSCOPIC TOTAL EXTRAPERITONEAL TESTICULAR DESCENT FIXATION IN THE TREATMENT OF INGUINAL CRYPTORCHIDISM IN CHILDREN

Objective: To explore the safety and feasibility of transumbilical single-site laparoscopic completely extraperitoneal approach for testicular descent in the treatment of inguinal cryptorchidism in children. Methods: A total of 63 cases of pediatric cryptorchidism treated with transumbilical single-site laparoscopic completely extraperitoneal approach testicular descent fixation (extraperitoneal approach group) from April 2023 to April 2025 were retrospectively analyzed, as well as traditional transumbilical single site surgery during the same period. Site: Clinical data of a total of 64 children who underwent laparoscopic descending testicular fixation (abdominal approach group). The general condition of the children, operation time, intraoperative blood loss, hospitalization time, postoperative complications and other indicators were collected. Results: The surgical procedures of both groups of patients were smooth. There were no surgery-related complications such as testicular retraction, testicular atrophy, or incision infection. One case in the abdominal approach group suffered from choking on milk while eating after surgery, but recovered well after treatment. The average operating time of the extraperitoneal approach group was 62.5 minutes, which was not significantly different from that of the intraperitoneal approach group (the average operating time of the intraperitoneal approach group was 62.75 minutes, P=0.91). There was no significant difference in intraoperative blood loss between the two groups (P=1). During the postoperative follow-up of 2 to 7 months, no case in the two groups required secondary surgery, and there were no recent postoperative complications. Conclusion: Transumbilical single-site laparoscopic total extraperitoneal approach for the treatment of children with inguinal cryptorchidism by descending testicular fixation has less trauma, less interference with abdominal organs, faster recovery, lower incidence of postoperative complications, and the therapeutic effect is comparable to that of traditional laparoscopic surgery. The effect is equivalent, the efficacy is reliable, and it is worthy of clinical application.
