Hydatid liver cyst perforation into the digestive tract

Complications of Liver hydatid disease include those related to the compres sion of adjacent viscus, to the infection of the cyst's contents or to the perforation of the cyst. Perforations into hollow abdominal organs are rare , and can occur secondary to the infection of the cyst or to a primary path ology of the perforated organ. We report on 2 cases of perforation of a liv er cyst into the duodenum, 1 due to the presence of a duodenal ulcer, and 1 secondary to a hydatid abscess. The surgical treatment of the lesions and their complications was, in both cases, successful.
