[Histomorphology of the liver by damage with phenolisatine-containing laxatives (Recurrent chronic cholangiohepatitis)].

In the case of 36 female patients who were anamnestically known to have taken laxatives, semiquantitative histological investigations with laparoscopically obtained liver needle biopsies were effected after the exposition with preparations containing phenolisatine. The time gap until exposition was 12 to 24 h (16 cases), 48 h (8 cases), 72 to 96 h (4 cases) and 7 to 14 days (4 cases). The histological result after the exposition is an acute cholangiolitis of the allergic-hyperergic type with edema and a dense eosinophile infiltration of the portal fields with destruction of the epithelium of preformed bile ducts and portally proliferated ductles. In addition, the parenchyma of the liver shows a pleomorphism of the cells in form and colour with a cellular edema and with disseminated acidophilic necroses and necrobioses of the individual cells as well as with little reactive proliferation of the Kupffer's cell. After a period of 8 days the acute process has more or less subsided. Also, in the majority of cases there are histological signs of an aggressive chronic hepatitis of type IIa, partially in the active stage with piece-meal necroses and partially stabilized or in the process of healing. A transition to the picture of hepatitic cirrhosis is possible. In serious cases the picture of a chronic non-purulent destructive cholangitis can be simulated by the hepatocellular and canalicular damage. Thirty-one bioptic pre-examinations from the same results, whereby the acute cholangiolitical exacerbation can be attributed to an exposition of the patients themselves. The clinical picture of the phenolisatine damage in its entirety is induced by medication and is described as a recurrent chronic cholangiohepatitis. Similarities exist between the liver damages caused by chlorpromazine and arsphenamine. When medication is discontinued, the morphologic substrate recedes leaving behind an inactive fibrosis or cirrhosis. The formal and known causal pathogenetic connections are discussed with regard to this clinically important liver disease. Guidelines are then given for histological diagnosis of this damage caused by medication. 14% of the female patients with a histological picture of aggressive chronic hepatitis and hepatitic cirrhosis are affected by this type of liver damage.
