[Experiences with surgical therapy of hepatic echinococcosis]

Between January 1984 and December 1990, 56 patients with hydatid liver disease were treated surgically at our Department. Diagnosis was made by using clinical criteria, serology and imaging techniques. Most frequent clinical symptom was abdominal pain or local discomfort (38 patients, 68%). Plain X-ray of the abdomen was helpful in 20 patients (36%), liver ultrasound in 53 (93%) and computerised tumorgraphy in 56 patients, (100%). The immunoelectrophoresis test of "arc 5" was sensitive in 51 patients (91%). Thirty patients (53%) underwent partial resection and omentoplasty, 17 patients (30%) underwent external drainage, two cystic resection (3%), one left lateral lobectomy (2%) and six (11%) underwent omentoplasty and T-tube insertion. Fatal complications did not occur. Four patients developed hepatic abscess (7%), three wound infection (5%), one bowel obstruction (2%) and in five instances (8%) drainage was maintained for more than three months. Of the 49 patients available for follow-up (87%), three (6%) developed recurrent disease.
