RESUMO
Lymphocytic gastritis is a recently described gastric inflammation, characterized by an increased intraepithelial lymphocytic infiltrate mainly composed of T-lymphocytes. Endoscopically it correlates mainly with diffuse varioliform gastritis. Ménétrier's disease is a hypertrophic gastropathy with enlarged gastric folds. The histological picture is that of foveolar hyperplasia and glandular cysts of the mucosa. A few small series of lymphocytic gastritis with microscopic and endoscopic features of Ménétrier's disease have been published previously. We describe a similar case associated with a gastric adenocarcinoma.

In 18 high-risk patients with acute cholecystitis and severe concurrent disease, we aspirated the gallbladder by using a percutaneous technique under ultrasound guidance. 17 of the 18 improved after aspiration, the only complication being local pain in 2. 13 of the 17 who improved remained free from biliary infections during a mean follow-up period of 14 months. 4 had an uncomplicated cholecystectomy 6-10 weeks later for recurrent cholecystitis. Percutaneous transhepatic gallbladder aspiration is a safe and effective procedure in critically ill patients with acute cholecystitis.

In 95 consecutive patients with proven colonic carcinoma, the tumor was detected by routine sonography in only half of the patients. However, in 22 out of 23 tumors of the right colon, a correct diagnosis was suggested by sonography (sensitivity 95.5%). Although not suitable as a first choice screening procedure for colorectal cancer, routine abdominal ultrasound can detect even non-suspected colonic tumors, especially in the ascending colon. Since the specificity of ultrasound is probably low, diagnosis must be confirmed by X-ray and/or endoscopy.

Three cases of dilated abdominal left paraaortic lymphatic duct are described. The diagnosis was established by means of sonography and confirmed with lymphography in all three patients. A sonographically guided puncture of the lymphatic duct was performed in one patient. Dilatation of these lymphatic ducts was possibly the consequence of previous upper abdominal surgery in two patients and a coronary bypass operation in one.
