The treatment of reflux disease did not changed. PPI treatment remains the first line treatment and surgery a second line treatment. The effect of surgery in reflux disease reduces and, after ten years, a part of the operated patients needs PPI again. The triple therapy is the treatment of choice of Helicobacter pylori infection. Patients with persistent Helicobacter pylori infection, after a first treatment, should be treated with a sequential treatment. PPI are effective in the prevention of gastroduodenal lesions and in the treatment of dyspeptic symptoms during NSAID treatment. IPP should be given to all patients presenting dyspeptic symptoms under NSAID or COX-2 administration.

There are no real therapeutical acquisitions in the year 2006. The latest breakthroughs related to peptic disease treatment are the subject of this article. In particular various therapeutic procedures in reflux disease, including Barrett's oesophagus are developed here. Two important items were emphasized in the treatment of gastric and duodenal ulcers, in particular Helicobacter pylori eradication and the treatment of bleeding ulcer. Prophylaxis of gastrointestinal lesions due to AINS is also approached in detail.

Hepatic portal gas in adults: review of the literature and presentation of a consecutive series of 11 cases.

BACKGROUND: Hepatic portal venous gas (HPVG) in adults is a rare entity. The underlying pathologic condition is usually an intestinal ischemia, but it has been reported in association with a variety of conditions. HYPOTHESIS: Miscomprehension of the underlying pathologic conditions has led to some confusion in the literature concerning its etiology, diagnostic methods, and clinical consequences. SETTING: Centre Hospitalier et Universitaire Vaudois, Lausanne, Switzerland, and District Hospital of Morges, Morges, Switzerland. METHOD: Between February 1, 1995, and May 30, 2000, eleven cases of HPVG were treated. These cases were retrospectively reviewed, together with a review of the literature to define the clinical significance of HPVG, the role of the computed tomographic scan, and the necessity of performing systematic emergency exploratory surgery. RESULTS: Two groups have to be distinguished-those who have HPVG with associated pneumatosis intestinalis and those who have HPVG without associated pneumatosis intestinalis. When associated with pneumatosis intestinalis, the cause is usually an intestinal ischemia and in a symptomatic patient it justifies systematic exploratory surgery. An abdominal computed tomographic scan including lung window settings to better identify air in the bowel wall will distinguish between these 2 groups. Pneumatosis intestinalis and HPVG due to bowel ischemia do not allow prediction of the severity of bowel wall damage. CONCLUSIONS: The cause of HPVG without pneumatosis intestinalis is variable. Good knowledge of the possible causes combined with the clinical picture and the abdominal computed tomographic scan is required to correctly identify the underlying cause of HPVG and to avoid unnecessary surgery.

Effect of investigator experience in CT colonography.

The aim of this study was to determine the impact of the learning curve on the diagnostic performances of CT colonography. Two blinded teams, each having a radiologist and gastroenterologist, prospectively examined 50 patients using helical CT scan followed by colonoscopy. Intermediate data evaluation was performed after 24 data sets (group 1) and compared with data from 26 subsequent patients (group 2). Parameters evaluated included sensitivity, specificity, false-positive and false-negative findings, time of data acquisition and interpretation. Using colonoscopy as the gold standard, sensitivity for CT colonography was for lesions >5 mm 63% for both teams for group 1 patients; for group 2 patients sensitivity was 45% for team 1 and 64% for team 2. Specificity per patients was for patient group 1 42% for team 1 and 58% for team 2; for patient group 2 it was 79% for both teams ( p=0.04 for team 1; p=0.2 for team 2). Comparing group 1 with group 2, the number of false-positive findings decreased significantly ( p=0.02). Furthermore, the mean time of data evaluation decreased from 45 to 17 min ( p=0.002) and the mean time of data acquisition from 19 to 17 min. With increasing experience, specificity and the time required for data interpretation improved and false positives decreased. There was no significant change of sensitivity, false-negative findings and time of data acquisition. A minimum experience of the readers is required for data interpretation of CT colonography.

Epinephrine versus epinephrine plus fibrin glue injection in peptic ulcer bleeding: a prospective randomized trial.

BACKGROUND: Peptic ulcer bleeding remains a disease with considerable morbidity and mortality. Epinephrine is the most widely used endoscopic injection agent, but bleeding recurs in 20% of high-risk cases. Fibrin glue might be an ideal injection agent, based on its physiologic properties, despite its demanding injection technique and high cost. The aim of this study was to determine whether the injection of fibrin glue in combination with epinephrine improves outcome for patients at high risk of recurrent bleeding. METHODS: Patients were prospectively randomized to injection of epinephrine alone (n = 70) or epinephrine plus fibrin glue (n = 65). Endoscopy was repeated daily until the ulcer base was clean. All patients were treated with high-dose omeprazole. RESULTS: Initial hemostasis was 100% in both groups. There was no significant overall difference in rates of recurrent bleeding (24.3% and 21.5%, respectively, for epinephrine and epinephrine plus fibrin). When patients were stratified according to Forrest criteria, no significant difference could be found, although there was a trend toward less recurrent bleeding after fibrin injection of actively bleeding ulcers. There was no significant difference in the proportions of patients who required surgery (10% and 6%, respectively, for epinephrine and epinephrine plus fibrin). Mortality was the same (3%) in each group. CONCLUSIONS: Adding fibrin glue to epinephrine for injection treatment of bleeding peptic ulcers does not improve outcome. Fibrin glue might be of some value in selected cases.
