Surgical treatment of hepatic hydatid disease.

The results of surgery in 38 patients with hepatic hydatid disease are described. Cystectomy was done in four patients with small peripheral cysts. For them the mean postoperative stay was 8.2 days. Partial cystectomy, introflexion and omentoplasty were performed in 28 patients with uncomplicated large cysts. The mean postoperative stay for these patients was 8.6 days. One patient in this group died of massive hemorrhage and disseminated intravascular coagulation. Exploration of the common bile duct and choledochoduodenostomy were required in three patients who had large cysts complicated by rupture into the biliary tree. This complication resulted in a mean postoperative stay of 11.5 days. Three patients who had cysts complicated by pyogenic infection were treated with tube drainage. They were discharged with their tubes in place after a mean hospital stay of 26.5 days. Hydrogen peroxide 10% was used as a scolicidal agent and was successful in preventing dissemination. All patients underwent ultrasonography 3 months after surgery, and 28 (74%) were followed up by annual examination. There was no recurrence after a mean follow-up of 2.7 years. The results suggest that surgical treatment of hepatic hydatid disease should be governed by the size, location and complications of the cyst. The combination of partial cystectomy, introflexion and omentoplasty was safe and effective therapy for patients with large hepatic cysts uncomplicated by pyogenic infection.
