Pelvic hydatid (echinococcal) disease.

To study epidemiologic and clinical features of pelvic hydatid disease and discuss its management.A retrospective analysis of 11 cases of pelvic hydatid disease managed over 7 years and 8 months at the Maternity and Neonatalogy Unit, Tunisian Medical Center La Rabta, Tunis, Tunisia. All cases were identified from histopathologic reports.The 11 affected patients had a mean age of 41.6years (range, 22-79 years), 6 had a history of surgery for hydatid disease, 8 presented for chronic pelvic pain, and 1 was admitted for acute surgical abdomen. On physical examination, 6 had a pelvic mass. An ultrasound examination suggested the diagnosis preoperatively in 6. All were treated surgically. Primary laparoscopy was performed in 5 patients. Unroofing (or partial cystectomy) was performed in 6 patients and complete cystectomy in 4. The postoperative course was uneventful in all cases. Recurrence occurred only in 1 patient, 6 months after initial surgery.Pelvic hydatid disease is rare and its diagnosis often difficult preoperatively. The treatment mainstay is surgery. The laparoscopic approach seems to be safe and effective, and may increasingly replace laparotomy.
