Summary

* To determine the percentage of children with impalpable testis who benefit from inguinal exploration after laparoscopic identification of cord structures entering the inguinal canal. * To determine the factors predicting the presence of inguinal testis in the previously mentioned children.

Detailed description

The undescended testis represents one of the most common disorders of childhood. The most useful classification of undescended testes is distinguishing palpable and non-palpable tests, and the location and presence of the tests decide clinical management. Approximately 80% of all undescended tests are palpable and the other 20% are impalpable. Among the 20% of non-palpable testes, 50-60% are intra-abdominal, canalicular, or peeping (right inside the internal inguinal ring). The remaining 20% are absent and 30% are atrophic or rudimentary. Diagnostic laparoscopy is the most useful modality for assessing nonpalpable testicles. The four most important structures to identify at laparoscopy are the testis, the testicular vessels, the vase deferens, and the patency of the processus vaginalis. The possible anatomical findings include spermatic vessels entering the inguinal canal (40%), an intra-abdominal (40%) or peeping (10%) testis, or blind-ending spermatic vessels confirming vanishing testis (10%). It permits the identification of three surgical scenarios that will lead to different courses of action: 1. Blind-ending vessels, which indicate a vanishing intra-abdominal testis, and no further exploration is necessary (10%) 2. Testicular vessels and vas entering the inguinal canal through the internal inguinal ring (34%).Inguinal exploration may find a testicular nubbin either in the inguinal region or in the scrotum, which may or may not be removed; or a healthy, palpable, undescended testicle amenable to standard orchidopexy. 3. Peeping (11%) or intra-abdominal tests (37%), which will require either an open or a laparoscopic approach. Although Rozanski et al. reported the first case of intratubular germ cell neoplasia originating from a testicular remnant, the necessity of removing nubbins is controversial.

Conditions

• Undescended Testis
• Inguinal; Testicle

Interventions

Type	Name	Description
PROCEDURE	Inguinal exploration	Inguinal exploration will be done for all the included patients.
PROCEDURE	Laparoscopy	All patients will have abdominal laparoscopy first to assess the location of the impalpable testis, the inguinal canal and the cord structures.
