Liver adenomatosis: reappraisal, diagnosis, and surgical management: eight new cases and review of the literature.

OBJECTIVE: Liver adenomatosis (LA) is a rare disease originally defined by Flejou et al in 1985 from a series of 13 cases. In 1998, 38 cases were available for analysis, including eight personal cases. The aim of this study was to review and reappraise the characteristics of this rare liver disease and to discuss diagnosis and therapeutic options. BACKGROUND: LA was defined as the presence of >10 adenomas in an otherwise normal parenchyma. Neither female predominance nor a relation with estrogen/progesterone intake has been noted. Natural progression is poorly known. METHODS: The clinical presentation, evolution, histologic characteristics, and therapeutic options and results were analyzed based on a personal series of eight new cases and an updated review of the literature. RESULTS: From a diagnostic standpoint, two forms of liver adenomatosis with different presentations and evolution can be defined: a massive form and a multifocal form. The role of estrogen and progesterone is reevaluated. The risks of hemorrhage and malignant transformation are of major concern. In the authors' series, liver transplantation was indicated in two young women with the massive, aggressive form, and good results were obtained. CONCLUSION: Liver adenomatosis is a rare disease, more common in women, where outcome and evolution vary and are exacerbated by estrogen intake. Most often, conservative surgery is indicated. Liver transplantation is indicated only in highly symptomatic and aggressive forms of the disease.

Contribution of cervical ultrasound and ultrasound fine-needle aspiration biopsy to the staging of thoracic oesophageal carcinoma.

This study was performed to evaluate the use of cervical ultrasonography and ultrasound-guided fine-needle aspiration for pretherapeutic staging of oesophageal cancer. 50 patients with a thoracic-oesophageal cancer (upper third = 8, middle = 36, lower = 6), previously untreated, underwent cervical ultrasonography to detect supraclavicular lymph node metastases (LN). An ultrasound fine-needle aspiration biopsy was attempted in 12 cases of suspected LN. 26 patients were operated on, of which 13 had surgical exploration of the neck. All patients were followed after treatment with special attention to the supraclavicular area. 14 patients (28%) were ultrasonography positive, 5 of 8 in the upper third, 9 of 42 in the two other thirds. Of the 12 patients where a fine-needle biopsy was attempted, 9 showed neoplastic cells (75%). 5 patients had cervical metastatic LN at surgery, and 5 other patients demonstrated supraclavicular LN metastases during the follow-up. There was one false positive and six false negatives from cervical ultrasonography and two false negatives of UGFAB (ultrasound-guided fine-needle aspiration biopsy). The sensitivity and the specificity of the cervical ultrasonography were 68 and 97%, respectively. The pretherapeutic staging was modified: 7 patients initially stage II-III were regraded to stage IV. Cervical ultrasonography is a reliable method of assessment of supraclavicular LN in thoracic oesophageal carcinoma.

Assessment of portal contribution to liver perfusion by quantitative sequential scintigraphy and Doppler ultrasound in alcoholic cirrhosis. Diagnostic value in the detection of portal hypertension.

To assess the portal contribution to liver perfusion, we carried out quantitative sequential scintigraphy in 110 patients with alcoholic cirrhosis (22 Child-Pugh class A, 39 class B, 49 class C) and 15 normal subjects. Duplex Doppler ultrasound found a type of intrahepatic circulation that made the standard scintigraphic procedure inaccurate in four cases of cirrhosis, which were reevaluated. Portal contribution to liver perfusion was lower in cirrhotics than in normal subjects (48.7 +/- 29% versus 78.4 +/- 6%; p < 0.001). The sensitivity of scintigraphy in detecting portal hypertension, based on portal contribution < or = 66%, was 61.8% (with a 100% specificity) compared with 66.7% for endoscopy (diagnosis based on existence of varices). The overall sensitivity of the two tests together was 86.1%. Portal contribution to liver perfusion was inversely correlated to Child-Pugh score (r = 0.53; p < 0.001), to prothrombin time (r = 0.52; p < 0.001), and to hepatic venous pressure gradient (r = 0.43; p < 0.001) and positively correlated to albuminemia (r = 0.42; p < 0.001). Concurrent alcoholic hepatitis and the existence of large portosystemic collaterals were related to a decrease in portal contribution to liver perfusion. We conclude that quantitative sequential scintigraphy, which shows a direct relationship between portal contribution to liver perfusion, on the one hand, and the amount of portosystemic shunting, the progression of liver disease, and/or acute liver injury, on the other, could serve as a diagnostic test for portal hypertension. The addition of scintigraphy improves the overall sensitivity of endoscopy.

[Value of hepatic angioscintigraphy combined to pulsed Echo-Doppler: application to the study of portal hypertension of cirrhotic patients. Apropos of 148 cases]. / Intérêt de l'angioscintigraphie hépatique couplée à l'écho-Doppler pulsé: application à l'étude de l'hypertension portale du sujet cirrhotique. A propos de 148 cas.

Quantitative hepatic angioscintigraphy was combined with duplex Doppler in order to study liver perfusion in normal subjects and in 148 patients with liver cirrhosis. The portal component of liver perfusion determined by scintigraphy was reduced in patients with liver cirrhosis and correlated to the development of cirrhosis and to porto-hepatic gradient pressure. Duplex Doppler allowed assessment of portal blood direction. Determination of portal blood flow was possible in only a few patients: portal blood flow was increased in the first stage of cirrhosis and then decreased; hepatofugal flow was observed only in the most severe stage. Angioscintigraphy and Duplex Doppler appear to be complementary in the study and follow-up of portal hypertension.
