Low prevalence of upper endoscopic gastrointestinal findings despite high frequency of alarm symptoms at the time of diagnosis in adult coeliac disea…
2020
Objectives Exclusion of organic disorders involving the upper gastrointestinal (UGI) is a mandatory step before considering a biopsy-avoidance diagnostic strategy for adult coeliac disease. We aim to evaluate the prevalence of alarm symptoms and coincidental UGI endoscopic findings at the time of diagnosis of coeliac disease. To develop consensus criteria to identify patients with coeliac disease requiring a gastroscopy and to evaluate whether alarm symptoms prompting gastroscopy were predictive of endoscopic findings. Methods Presenting symptoms and UGI endoscopic findings at diagnosis of coeliac disease were collected retrospectively in 278 adult patients with coeliac disease diagnosed in…

Use of flunitrazepam for sedation in digestive endoscopy. Our experience
Multicentric randomised study of
2017
Introduction Population-based eradication of Helicobacter pylori has been suggested to be cost-effective and is recommended by international guidelines. However, the potential adverse effects of widespread antibiotic use that this would entail have not been sufficiently studied. An alternative way to decrease gastric cancer mortality is by non-invasive search for precancerous lesions, in particular gastric atrophy; pepsinogen tests are the best currently available alternative. The primary objective of GISTAR is to determine whether H pylori eradication combined with pepsinogen testing reduces mortality from gastric cancer among 40–64-year-old individuals. The secondary objectives include ev…
Helicobacter pylori infection does not affect the early rebleeding rate in patients with peptic ulcer bleeding after successful endoscopic hemostasis…
2003
Background and study aims Eradication of Helicobacter pylori infection can reduce the rebleeding rate of peptic ulcer bleeding in the long term. There are few data on the influence of H. pylori on the rebleeding rate in the acute phase of bleeding however. We therefore prospectively investigated the influence of H. pylori infection on the early rebleeding rate in patients who had undergone successful endoscopic hemostasis treatment for peptic ulcer bleeding. Patients and methods Between January 1996 and November 2000 all patients with peptic ulcer bleeding were evaluated consecutively. The diagnosis of H. pylori infection was made at index endoscopy, using histology and the rapid urease tes…
Kinin receptor status in normal and inflammed gastric mucosa
1997
No documented studies have been reported on the presence of B1 and B2 kinin receptors in the mammalian gastric mucosa. This first study aimed to immunolocalise sites of B1 and B2 kinin receptors in the human pyloric gastric mucosa and to evaluate its role in gastritis. Biopsies were obtained from patients with dyspepsia during endoscopic examination of the patient. The diagnosis and grading of the gastritis was performed on histological examination. Sections were immunostained for both B1 and B2 receptors using rabbit anti-human B1 and B2 kinin receptor antibodies. Control tissue was obtained from partial gastrectomy specimens, following surgical excision of the antrum for duodenal ulcers. …
Ikivėžinių skrandžio gleivinės pokyčių paplitimas Helicobacter pylori sukelto lėtinio gastrito metu tarp Rytų Europos (Lietuvos, Latvijos) ir Azijos …
2007
The aim of the study was to compare the prevalence and severity of precancerous condition – gastric atrophy and intestinal metaplasia (IM) between Eastern European (Lithuania and Latvia) and Asian (Taiwan) countries in population older than 55 years. Methods. Patients aged 55 years and older, referred for upper endoscopy due to dyspeptic symptoms, were included in the study. Gastric biopsies were histological investigated according modified Sydney classification. Helicobacter pylori (H. pylori) was detected if any two of three methods (urease test, histology, and serology) were positive. Results. Overall 322 patients included: 52 from Taiwan (TW), 171 from Latvia (LV) and 99 from Lithuania …
Test-and-treat strategy for Helicobacter pylori (HP) infection in older patients.
2010
Abstract Despite Helicobacter pylori (HP) infection is highly prevalent in older populations, low rates of HP diagnosis and eradication are reported in older persons, even in geriatric wards. We aim to evaluate the results of a HP-eradicating program in a sample of older patients in relation to dyspeptic symptoms and to endoscopic findings. A pool of 140 subjects (female/ale = 86/54, mean age 68.6 ± 5.4 years) with positive C 13 -urea breath test were recruited, clinically evaluated to investigate the presence and characteristics of dyspepsia and abdominal pain, and underwent gastric endoscopic examination. HP-eradication was obtained in 87.9% of subjects with first-line triple therapy, reg…
[Endoscopic treatment of gastric carcinoid. Report of a clinical case]
2003
We report on a case of a gastric carcinoid of the sporadic type successfully treated by endoscopic electroresection. From January 1998 to October 2002, 1523 gastroscopies were performed in the Palermo University General Emergency Surgery and Organ Transplant Unit. In a 59-year-old man with a history of dyspepsia, a sessile polypoid gastric lesion was observed in the gastric corpus. Laboratory data were normal. The lesion was successfully treated by electroresection. Histological evaluation revealed an 8-mm-diameter well-differentiated neuroendocrine polypoid tumour infiltrating the muscularis mucosa. According to Rindi et al.'s classification, the polyp was a carcinoid of the sporadic type.…
The accuracy of flexible spectral imaging colour enhancement for the diagnosis of gastric intestinal metaplasia
2014
Background Targeting biopsies on the basis of visual recognition of mucosal changes in the stomach instead of the currently accepted random biopsy sampling may be attractive. Aim The aim of this study was to evaluate the accuracy of endoscopic findings using flexible spectral imaging colour enhancement (FICE) for intestinal metaplasia (IM) in the gastric mucosa. Methods A consecutive cohort of 126 individuals aged over 50 years (27% men) was subjected to upper endoscopy using FICE. Histological assessment (per patient and per biopsy) was considered the gold standard to accuracy estimates. Results Histological assessment revealed IM in 50% of the individuals [OLGIM (operative link on gastric…
Mechanism of fatal air embolism after gastrointestinal endoscopy.
1998
Although venous air embolism is a known complication in medical practice in general, only a single case of upper gastrointestinal endoscopy complicated by venous air embolism with consecutive acute cardiovascular failure has so far been described in literature. Here we show that gastroscopy may be accompanied by massive, i.e. fatal venous air embolism. If a vessel in the gastrointestinal tract is exposed but does not collapse (in the case of a gastric ulcer, for example) air insufflated under pressure by the gastroscope may lead to a fatal air embolism. Our tests using a commercial gastroscope revealed that an overpressure of up to 43 kPa (kiloPascals) is reached without the rinsing functio…
