Impact of laparoscopy for diagnosis and treatment in patients with disorders of sex development

Abstract

ObjectiveTo review laparoscopy in patients with disorders of sex development (DSD) in order to clarify its usefulness in diagnosis, devising subsequent therapeutic strategies and managing patients with various conditions. Patients and methodsBetween April 1992 and December 2012, 29 laparoscopic surgeries were performed in 25 DSD patients. Among them, ten were diagnostic laparoscopy including gonadal biopsy, and 19 were therapeutic laparoscopy. Surgical procedures and complications were evaluated. ResultsFor diagnostic laparoscopy, laparoscopic gonadal biopsy was performed in three patients. Inspection, with or without open gonadal biopsy, was performed on four out of seven patients with 46XY DSD or mixed gonadal dysgenesis (MGD). Additional surgery was planned and performed based on diagnostic laparoscopic findings in six out of seven patients. In the three patients with ovotesticular DSD, the gonadal pathology was diagnosed as: testis/ovary in one, testis/ovotestis in one and ovary/ovotestis in one – this was from the laparoscopic inspection and/or gonadal biopsy. However, the final diagnoses were bilateral ovotestis in two patients and ovary/ovotestis in one patient.For therapeutic laparoscopy, surgical procedures were: gonadectomy in 17 patients (bilateral in 13, unilateral in three, partial in two); hysterectomy in two patients; orchiopexy in one; and sigmoid vaginoplasty in one patient (included multiple procedures). There were no severe perioperative complications. In the four patients with a history of diagnostic laparoscopy, no severe intra-abdominal adhesions that would disturb therapeutic laparoscopic surgery were observed. ConclusionWhile diagnostic laparoscopy was helpful in devising a therapeutic surgical strategy in most of the patients with DSD who were suspected as having complex gonadal status or Müllerian duct derivatives, attention must be paid to precisely diagnosing the gonadal status in ovotesticular DSD. On the other hand, therapeutic laparoscopic surgeries were valuable procedures in treating DSD patients, even with a history of previous diagnostic laparoscopy.
