Video-assisted gonadectomy in children with Ullrich Turner syndrome or 46,XY gonadal dysgenesis.
Patients with dysgenetic gonads carry a high risk for the development of gonadal neoplasia. The aim of the study is to evaluate indications and feasibility of laparoscopy and video-assisted prophylactic gonadectomy in children with Ullrich Turner syndrome (UTS) or 46,XY gonadal dysgenesis (GoDy). Between 1996 and December 2002 five girls with UTS and nine patients with 46,XY GoDy (female gender role) were explored by laparoscopy. Video-assisted salpingo-oophorectomy or gonadectomy was performed using a three-port technique. Prophylactic salpingo-oophorectomy was exclusively performed in UTS patients with proven presence of translocated parts of the Y chromosome. In three patients with 46,XY GoDy laparoscopy was followed by surgical revision of the groin and open gonadectomy in four patients. In two cases with UTS the removed streak gonads contained small unilateral tumours stage pT1a, and in four cases of 46, XY GoDy histopathological investigation revealed bilateral neoplasms stage pT1b. We found the following tumour types: gonadoblastoma, dysgerminoma, testicular intraepithelial neoplasia, and mature teratoma. In conclusion, investigative laparoscopy gives a good image of the internal genital structures and allows the safe removal of the dysgenetic gonads during the same operation. The high rate of gonadal tumours underlines the indication for early gonadectomy in these patients.
