    Abstract:
    Introduction: Undescended testis is a relatively common congenital anomaly in male children with a prevalence of 1%-2% in live births. Upon discovering an empty scrotum, it is important to determine whether the testis is palpable, ectopic, retractile, or nonpalpable. A canalicular or "emergent" testis is a peeping one that freely slides to and fro between the abdominal cavity and inguinal canal. It may be impalpable initially, but at a time, it emerges from the internal ring to be palpable when it is "milked" down (where it was concealed from detection). It is reported that 15%-40% of cryptorchidism are viable peeping/canalicular testis. The laparoscopic approach for treating intracanalicular undescended testes offers many advantages over open inguinal orchiopexy. It maintains the integrity of the inguinal canal and eliminates the need to divide the epigastric vessels during dissection. The ability to dissect the testicular vessels at a higher level would increase the vessel length available to bring the testis down to the scrotum without strain. The aim of this study is to present our experience and evaluate laparoscopic approach for management of intracanalicular testes regarding operative safety, efficacy, and postoperative outcomes. Patients and Methods: This is a prospective study conducted at Department of Pediatric Surgery, MCH Hospital, Bisha, Saudi Arabia and Pediatric Surgery Department, Al-Azhar University Hospitals, Cairo, Egypt, in the period from October 2018 to August 2020 to evaluate the safety and efficacy of laparoscopic orchiopexy for intracanalicular testis. Patients with retractile testes, ectopic testes, testes located distal to the external inguinal ring, and nonpalpable testes were excluded from the study. Results: The study was conducted on 62 male children with 70 intracanalicular (peeping) testes, with age range from 8 months to 48 months (mean age: 24 months). Among them, 26 cases (∼42%) were left-sided, 28 (∼45%) were right-sided, and 8 (∼13%) cases were affected bilaterally. Postoperatively, all testes maintained good size without postoperative hydrocele or inguinal hernia. One case (1.4%) required open redo-orchiopexy because of testicular re-ascent to the level of scrotal neck. Moreover, there was no evidence of testicular atrophy confirmed by postoperative ultrasonography. All patients had good satisfied cosmetic results obtained by parent's questionnaire at postoperative follow-up visits. Conclusion: Laparoscopic orchiopexy for management of (intracanalicular) undescended testes is safe, effective, less invasive, without disturbance of inguinal canal anatomy, and with better cosmetic results.
