Ultrasonographic findings in portal hypertension: correlation with the presence and size of oesophageal varices.

This study assesses the usefulness of ultrasonography in the diagnosis of portal hypertension. Several ultrasonographic signs were correlated with the presence and size of oesophageal varices detected by endoscopy in 32 patients suffering from alcoholic liver cirrhosis. Ultrasonography is proposed as a simpler and earlier method for screening of portal hypertension than endoscopy.

Possible role of pirenzepine on the release of pancreatic polypeptide in duodenal ulcer patients: preliminary results of a randomized cross-over study.

The effects of repeated oral doses of pirenzepine (100 mg daily for 7 days) and antacid (Maalox, 105 ml daily for 7 days) on the test-meal-stimulated release of pancreatic polypeptide (PP) were evaluated in 7 duodenal ulcer outpatients by means of a randomized cross-over study, with a wash-out period of one week between pirenzepine and antacid administration. The effects of pirenzepine (100 mg daily for 7 days) were also evaluated in 5 healthy adult volunteers. The stimulus test was performed on each fasting patient two days before the treatment started and after a 7-day treatment. Venous blood samples were obtained before the test meal (basal) and 3, 10 and 30 minutes after it. Plasma PP levels were estimated by means of a specific RIA. The results obtained showed that pirenzepine significantly inhibits the PP response to the test meal in the duodenal ulcer patients and in the healthy volunteers. The above-mentioned effects suggest that one of the mechanisms of action on the therapeutic activity of pirenzepine on peptic ulcer might be explained by the preservation of pancreatic secretion unimpaired by an increase in PP release after meal stimulus.

An evaluation of endoscopic retrograde pancreatography (ERP) in chronic and relapsing acute pancreatitis.

The results of ERP carried out in a series of cases of established and suspected chronic and acute relapsing pancreatitis are presented. Radiological findings are divided into major and minor alterations of the pancreatic secretory system. X-ray findings are easy to interprete in chronic pancreatitis with major alterations. Minor anomalies of the pancreas are difficult to interprete in the absence of supporting evidence. Biliary tract involvement is useful for diagnosis of chronic pancreatitis.

[Eosinophilic gastroenteritis. Report of a clinical case].

An unusual case of eosinophilic gastroenteritis is described, together with its differential diagnosis from allergic enteropathy. Numerous biopsies and other instrumental examinations pointed to small intestine as the only site and eosinophilic enteritis as a suitable classification. Disappearance of the clinical symptoms was obtained with corticosteroid management in the space of 6 months.

Endoscopic ultrasonography in the diagnosis of gastric submucosal tumor.

Endoscopic ultrasonography contributed to a correct diagnosis in 24 of 25 patients with gastric submucosal tumor, including 10 extrinsic compressions and 14 intraparietal growths. Leiomyoma and lipoma were easily recognized. In one case, an unusual group of gastric varices was clearly differentiated from a pedunculated polyp prior to polypectomy. In gastric submucosal tumors, endoscopic ultrasonography can greatly reduce the need for aggressive and risky biopsy techniques or exploratory laparotomy.

Assessment of portal hypertension by endoscopic ultrasonography.

Endoscopic ultrasonography (EUS) was performed in 40 patients with portal hypertension (PH) and in 48 control subjects. The azygous, splenic, mesenteric, and portal veins were displayed in both groups. However, esophageal and gastric varices, periesophageal and perigastric collateral veins, and submucosal gastric venules were displayed only in patients with portal hypertension. EUS was inferior to endoscopy in detecting and grading esophageal varices (p less than 0.0005), but EUS was superior in the detection of varices in the fundus of the stomach (p less than 0.0005). Detection of periesophageal veins by EUS increased with increasing diameter of esophageal varices at endoscopy (57% in grade 1, 89% in grade 2, and 100% in grade 3), and there was a direct correlation between endoscopic grade and the diameter of the periesophageal collateral veins at EUS. The diameter of the azygous vein by EUS at its distal and proximal margins was significantly greater in patients with PH (p less than 0.001); the EUS diameter of the azygous vein was significantly larger with variceal grade 2 compared with grade 1 (p less than 0.02 and p less than 0.01, respectively). In portal hypertensive gastropathy, endoscopic and EUS detection were coincident. No correlation was found between the presence of portal hypertensive gastropathy, endoscopic grade of esophageal varices, and detection of gastric varices at EUS.

Severe acute gastritis associated with Helicobacter pylori infection.

We describe the case of a young female referred to our unit because of acute upper abdominal symptoms. Upper gastrointestinal endoscopy showed a gastric picture resembling lymphoma or acute non-steroidal anti-inflammatory drug gastropathy (deep, large and irregular ulcers), but the clinical history and the histological examination of gastric biopsies were consistent only with acute gastritis Helicobacter pylori-correlated. The patient was treated with omeprazole and antibiotics with complete recovery. As the patient's cat had suffered from an acute gastrointestinal distress two weeks earlier, a case of zoonosis was hypothesized and an upper gastrointestinal endoscopy was performed also on the cat. Unfortunately, we were not able to detect Helicobacter pylori in the cat gastric mucosa, but only urease-producing spiral microorganisms. Possible sources of infection and pathogenetic mechanisms of the severe gastritis are discussed.

Cancer of the esophagus--endoscopic ultrasound: selection for cure.

Several treatment options are available to treat esophageal cancer. Ideally, treatment should be individualized, based on the projected treatment outcome for that individual. Accurate staging of the extent of the disease at the time of diagnosis offers the most rational attempt at stratifying patients into categories that can be used to affect treatment choices. Endoscopic ultrasonography (EUS) is the most accurate nonoperative technique for determining the depth of tumour infiltration and thus is accurate in predicting which patients will be able to undergo complete resection. EUS is also being used for tumour staging in order to guide treatment decisions in patients with esophageal cancer.
