Human echinococcosis is still endemic in some areas of the world, incl
uding Mediterranean countries. Because there is no effective medical t
herapy, surgery remains the principal mode of treatment. A consecutive
series of 132 patients operated on for liver hydatid disease between
January 1977 and February 1993 were analyzed. There were 60 men (45.4%
) and 72 women (54.6%) aged 31 to 88 years (mean 56 years). The right
lobe of the liver was affected in 68 cases (51.5%), the left lobe in 3
1 cases (23.5%), and both lobes in 14 cases (10.6%); there were multip
le liver cysts in 7 cases (5.3%), concomitant cysts in other parenchym
al organs in 4 cases (3.0%), and disseminated intraabdominal hydatid d
isease in 8 cases (6.1%). Clinical symptomatology consisted of abdomin
al pain, fever, jaundice, urticaria, and an abdominal mass. Preoperati
ve diagnosis was established using imaging studies: plain abdominal fi
lms, ultrasonography, computed tomography, and serologic tests. Three
patients (2.3%) underwent simple closure without drainage, 7 patients
(5.3%) cyst excision, 4 patients (3.0%) marsupialization, 1 patient (0
.8%) left lateral segmentectomy, 15 patients (11.3%) external drainage
, 69 patients (52.3%) omentoplasty, and 33 patients (25.0%) combinatio
ns of procedures. Postoperative morbidity was low and consisted of hep
atic abscess development, wound infection, bowel obstruction, and bili
ary leaks. Six patients (4.5%) had recurrent disease. One patient died
during the postoperative period because of septic complications. Amon
g the surgical techniques we used, excision of the cyst (when feasible
) and omentoplasty produced the lowest complication rates and the best
clinical results.
