As known from several observational and retrospective endoscopic studies the prevalence of gastric inlet patches (GIPs) of the cervical esophagus is estimated between 1-10%. In most cases GIPs are found within endoscopy as an incident finding, since in most cases they are harmless and do not cause any symptoms. None the less several data exist where an association between GIPs and globus sensations is discussed. Case reports even refer to bleeding complications and moreover to malignant transformations of GIPs.
As a result of the assumed association of GIPs and globus sensations we performed a pilot trial. Here we included 10 patients with globus and GIPs and were able to demonstrate a significant symptom relief after ablation of the GIP (Meining et al, Endoscopy 2006). To exclude a potential placebo-effect we concluded a multicenter and sham controlled trial where we imposingly were able to prove the symptom relief after ablation of the GIPs (Bajbouj et al, Gastroenterology 2009).
All patients, who are scheduled for esophagogastroduodenoscopy (EGD) in any of the above mentioned endoscopical departments are routinely standardized asked whether they have any hints suggestive for globus sensations (modified globus-questionnaire from Deary et al., J Psychosom Res 1995). Concurrently it is noted, whether the patients have endoscopical detected GIP. All GIPs are biopsied and examined in one institute. Together with anamnestic data (age, gender) a talley sheet gives a survey of all relevant information to prove or disprove following hypotheses.
1. The presence of GIPs is associated with globus sensations. In other words: Do patients with globus sensations significantly more often have GIPs?
2. GIPs are not congenital, they arise in the course of the time and become symptomatic. In other words: Do GIPs significantly occur in more elderly people?
3. The more increased the GIPs diameter is the more likely globus sensations are present? In other words: Do huge GIPs cause significantly more often symptoms than small ones?
4. The more mucus-producing mucosa is histologically proven the more likely globus sensations are present? In other words: Do we find more cardiac mucosa in patients with symptoms than fundus mucosa?

Symptomatic heterotopic gastric mucosa also known as cervical inlet patch (CIP) may be present in varying shapes and causes symptoms of laryngopharyngeal reflux like globus sensations, hoa...
Globus sensations are associated with gastroesophageal reflux disease as well as the presence of a gastric inlet patch. No controlled trial exists on whether ablation of the cervical heter...
The heterotopic gastric mucosa found in the cervical esophagus was first described in 1805 and affects 10-15% of individuals undergoing esophagogastroduodenoscopy. It leads to laryngophary...
The aim of the study is to determine whether Narrow Band Imaging(NBI) should be routinely used during esophagus inspection at diagnostic gastroscopy.
Radiofrequency ablation (RFA) is a mainstay of treatment for patients who have Barrett's esophagus (BE) with dysplasia. For unclear reasons, Barrett's esophagus recurs after successful RFA...
Conventional endoscopy often misses early gastric cancers with minimal red discoloration because they cannot be distinguished from inflamed mucosa. We treated a patient with a small early gastric canc...
A 62-year-old male with long-standing esophageal reflux underwent endoscopy at an outside institution that reported multiple polypoid lesions in upper esophagus and a small focal area of nodular mucos...
Vagal denervation of that part of the STOMACH lined with acid-secreting mucosa (GASTRIC MUCOSA) containing the GASTRIC PARIETAL CELLS. Since the procedure leaves the vagal branches to the antrum and PYLORUS intact, it circumvents gastric drainage required with truncal vagotomy techniques.
A species of gram-negative, spiral-shaped bacteria found in the gastric mucosa that is associated with chronic antral gastritis. This bacterium was first discovered in samples removed at endoscopy from patients investigated for HELICOBACTER PYLORI colonization.
A subtype of cholecystokinin receptor found primarily in the CENTRAL NERVOUS SYSTEM and the GASTRIC MUCOSA. It may play a role as a neuromodulator of dopaminergic neurotransmission the regulation of GASTRIC ACID secretion from GASTRIC PARIETAL CELLS.
Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE. It is often associated with HELICOBACTER PYLORI infection or consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
Retrograde flow of gastric juice (GASTRIC ACID) and/or duodenal contents (BILE ACIDS; PANCREATIC JUICE) into the distal ESOPHAGUS, commonly due to incompetence of the LOWER ESOPHAGEAL SPHINCTER.
Barrett’s esophagus is a condition in which the tissue lining the esophagus—the muscular tube that carries food and liquids from the mouth to the stomach—is replaced by tissue that is similar to the intestinal lining. This process is ca...
