ABSTRACT
A retrospective study of 80 patients operated on for hydatid cysts located on the superoposterior aspect of the right lobe of the liver (segments VI, VII, VIII) is presented. Right thoracotomy was performed in 30 patients, and 50 patients were operated on through bilateral subcostal incisions. The two approaches were compared in terms of radicality and morbidity. The transabdominal approach produced superior results and fewer postoperative complications, resulting in a shorter hospital stay (11 +/- 5 vs. 18 +/- 8 days). Total cystopericystectomy was feasible in 30% of patients operated on transabdominally and in 6% of those approached transthoracically. The rest of the patients were offered partial pericystectomy, except three in the thoracotomy group who underwent simple drainage of the cavity. We recommend that the transabdominal approach be the first choice for treatment of liver hydatid cysts irrespective of their location and size. We abandoned the transthoracic approach for cysts located on the superoposterior aspect of the right liver lobe in 1996. The transabdominal approach enables the surgeon to treat liver hydatidosis in a more radical, safer manner than does the transthoracic approach.
