The Use of Confocal Laser Endomicroscopy in Diagnosing Barrett's Esophagus and Esophageal Adenocarcinoma.

Confocal laser endomicroscopy (CLE) is a diagnostic technique that enables real-time microscopic imaging during microscopic examination and evaluation of epithelial structures with 1000-fold magnification. CLE can be used in the diagnosis of various pathologies, in pneumology, and in urology, and it is very widely utilized in gastroenterology, most importantly in the diagnosis of Barrett's esophagus (BE), esophageal adenocarcinoma (EAC), biliary strictures, and cystic pancreatic lesions. A literature search was made in MEDLINE/PubMed and Google Scholar databases while focusing on diagnostics using CLE of BE and EAC.

Autoimmune Diseases of Digestive Organs-A Multidisciplinary Challenge: A Focus on Hepatopancreatobiliary Manifestation.

It is well known that some pathological conditions, especially of autoimmune etiology, are associated with the HLA (human leukocyte antigen) phenotype. Among these diseases, we include celiac disease, inflammatory bowel disease, autoimmune enteropathy, autoimmune hepatitis, primary sclerosing cholangitis and primary biliary cholangitis. Immunoglobulin G4-related diseases (IgG4-related diseases) constitute a second group of autoimmune gastrointestinal, hepatobiliary and pancreatic illnesses.

Causes of Exocrine Pancreatic Insufficiency Other Than Chronic Pancreatitis.

Exocrine pancreatic insufficiency (EPI), an important cause of maldigestion and malnutrition, results from primary pancreatic disease or is secondary to impaired exocrine pancreatic function. Although chronic pancreatitis is the most common cause of EPI, several additional causes exist. These include pancreatic tumors, pancreatic resection procedures, and cystic fibrosis.

infection and other bacteria in pancreatic cancer and autoimmune pancreatitis.

() is an infectious agent influencing as much as 50% of the world's population. It is the causative agent for several diseases, most especially gastric and duodenal peptic ulcer, gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma of the stomach. A number of other, extragastric manifestations also are associated with infection.

Achalasia and acromegaly: Co-incidence of these diseases or a new syndrome?

Background: Acromegaly is a disorder associated with hypersecretion of growth hormone, most usually caused by a pituitary adenoma. Dysmotility of the gastrointestinal tract has been reported in acromegalic patients. Achalasia is a disorder characterized by aperistalsis of the oesophagus with incomplete lower oesophageal sphincter relaxation and whose aetiology remains unknown.

[Diagnostics and therapy of chronic pancreatitis according to UEG guidelines].

Chronic pancreatitis is one of the diseases whose incidence is slightly increasing long-term. Apparently this is related to our current dietary habits and to the way of life in industrialized societies in general. In recent years, chronic pancreatitis has experienced greater diagnostic accuracy and reliability, although we are still unable to diagnose the early stages of the disease.

[Confocal laser endomicroscopy in the diagnostics of esophageal diseases: a pilot study].

Background: Probebased confocal laser endomicroscopy (pCLE) is a novel diagnostic technique for endoscopy which enables a microscopic view at a cellular resolution in realtime. Endoscopic detection of early neoplasia in the distal esophagus is difficult and often these lesions can be missed. The aim of the pilot study was to obtain characteristic pCLE figures in esophageal diseases for following studies, and to evaluate the possible future role of pCLE in the diagnostics of dysplastic Barretts esophagus (BE) or early esophageal adenocarcinoma (EAC).
