Staged laparoscopic traction orchidopexy for impalpable testes: a preliminary study

Abstract

Laparoscopy is the gold standard to assess for presence of an intra-abdominal testis. However, techniques for the subsequent orchidopexy vary, and include the recently described staged laparoscopic traction orchidopexy (SLTO) (Shehata in Pediatr Surg 51(2):211–215, 2016). SLTO enables elongation of the testicular vessels without division, with initial success rates reportedly superior to Fowler–Stephens. We present the first UK data following a preliminary study using SLTO. 19 boys prospectively presenting with 22 intra-abdominal testes (IAT) underwent STLO in a single centre, with a median age of 2.5 years (IQR 1.4–5.2) at first stage. 3/19 (16%) boys had bilateral IAT and nine (41%) were left-sided. Pneumoperitoneum was established using 5 mm umbilical and 3 mm accessory ports in bilateral iliac fossae. The gubernaculum and lateral peritoneal attachments were divided prior to securing the intra-abdominal testis to the contralateral anterior abdominal wall with 2/0 Ti-cron™. Second-stage procedures were planned for 3–6 months later. The securing stitch was cut; an 11 mm STEP port was placed trans-scrotally to retrieve the testis and secured in a sub-dartos pouch. Outcome measures included palpable testes in the scrotum and surgical complications. 13/22 IAT have undergone follow-up. Twelve (92%) IAT were palpable in the scrotum following SLTO. There was one diathermy-related bladder injury necessitating laparoscopic repair, and 3/22 (13.6%) slipped sutures, requiring repeat first-stage procedures. Staged laparoscopic traction orchidopexy is a feasible technique, which can be performed as an alternative to Fowler–Stephens procedure, with potentially better outcomes for the testis. The complications described should be preventable as the technique evolves.
