Introduction Diagnostic laparoscopy is the gold standard for evaluating a child with impalpable undescended testis (UDT). During the diagnostic laparoscopy, if the vas and vessels are seen coursing through the inguinal canal, the standard norm is to explore the inguinal canal via an inguinal crease incision. In this study, however, we explored the feasibility of laparoscopic inguinal exploration without any additional inguinal crease incision. Materials and methods The prospective study was done from 1.1.2019 to 30.6. 2019 to assess the feasibility of the laparoscopic inguinal exploration in cases of impalpable undescended testis, where testicular vessels are found to course into the inguinal canal during a diagnostic laparoscopy. The data including the descriptive characteristics, intraoperative findings, and surgical technique were collected and analysed. Results There were 17 cases of impalpable UDT operated in the Department of Pediatric Surgery from January 2019 to June 2019. Mean age of the patients was 8.5 years (1–16 years). Two patients had testicular vas and vessels coursing through the inguinal canal, both of which underwent laparoscopic inguinal exploration. In both of these cases, vas and vessels were found to end in testicular nubbin, at the level of the neck of the scrotum, which were excised laparoscopically, thus avoiding the open inguinal incision. Conclusion Laparoscopic inguinal exploration is a feasible and attractive alternative in cases of impalpable UDT where testicular vas and vessels are found to course through the inguinal ring.
