R-R interval variability (RR variability) is increasingly being used as an index of autonomic activity. High-frequency (HF) power reflects vagal modulation of the sinus node. Since vagal modulation occurs at the respiratory frequency, some investigators have suggested that HF power cannot be interpreted unless the breathing rate is controlled. We(More)
Our aims were to develop a noninvasive predictive tool to identify cirrhotic patients with esophageal varices and to evaluate whether portal Doppler ultrasonographic parameters may improve the value of other predictors. One hundred forty-three consecutive compensated cirrhotic patients underwent upper gastrointestinal endoscopy. Fourteen clinical,(More)
Solitary small intestine hemangiomas are rare and usually present with overt bleeding or chronic anemia. Diagnosis is usually difficult because traditional imaging techniques often lack accuracy. Capsule endoscopy is a new diagnostic tool that has showed greater sensitivity than other methods to reveal causes of bleeding in the small intestine. A case of(More)
BACKGROUND Portal hypertensive gastropathy (PHG) is frequently found among patients with hepatic cirrhosis and at present the only way to detect and follow PHG is via endoscopy. OBJECTIVE To assess gastric and intestinal permeability and investigate its relationship to endoscopic findings and indices of portal hypertension and hepatic function. DESIGN(More)
Ľexérèse endoscopique des polypes gastriques et duodénaux a été reconnue comme une alternative valable par rapport au traitement chirurgical. Les auteurs rapportent les résultats ďune enquête italienne concernant les complications de la polypectomie endoscopique gastroduodénale.

We report the complications of perendoscopic sclerotherapy observed during treatment of oesophageal varices in 104 patients and 409 sclerotherapy sessions. Complications were related to each individual session and to the aim of the treatment (therapeutic or prophylactic). Major complications occurred in 17.3% of the patients treated: 13 cases of severe(More)
OBJECTIVE To evaluate the role of capsule endoscopy in the detection of causes of obscure gastrointestinal bleeding. METHODS Fifteen patients, nine males and six females, mean age 46 years (range 20-75 years), were investigated. All patients had undergone upper and lower gastrointestinal endoscopy with no evidence of causes of bleeding. Indication for(More)
