[Determination of amylase and lipase in peritoneal fluid: diagnostic value in ovarian cysts (author's transl)].

Two female patients aged 18 and 25 were admitted because of progressive abdominal distention, both had vague digestive complaints of several months onset, which was interpreted as ascitis. Needle aspiration yielded a clear fluid with an elevated amylase content. Lipase was within normal limits which suggested an extra-pancreatic process as the cause of amylase elevation. The sex of the patients, the non-progression of symptomatology together with good tolerance suggested the possibility of a giant ovarian cyst, which was confirmed by laparotomy. The value of lipase determination in fluid obtained by needle aspiration and high in amylase content, in ruling out pancreatic processes is discussed.
