Background/Aims: Changing trends in the Helicobacter pylori ( H. pylori ) eradication protocol have not been investigated after the publication of the third-revised Korean guideline in 2013. We aimed to analyze the clinical characteristics of H. pylori -infected patients alongside their treatment protocols using a common data model (CDM). Materials and Methods: A 16-year electronic health record (of 1,689,604 patients from 2004 to 2019) was converted into a CDM in Kangdong Sacred Heart Hospital. We extracted records of patients who underwent the rapid urease test or serum anti- H. pylori IgG assay. The treatment protocols were visualized using a sunburst plot. We investigated the clinical characteristics and medication history of patients who underwent a urea breath test after clarithromycin-based eradication therapy. Results: Out of 29,458 patients tested for H. pylori infection, 7,647 received a treatment protocol. Among them, 72.5% received a 7~14 days protocol comprising a proton pump inhibitor (PPI), amoxicillin, and clarithromycin. The proportion of patients treated with the first-line protocol (PPI, bismuth, tetracycline, and metronidazole) slightly increased from 1.9% (before 2014) to 3.3% (after 2014) ( P <0.001). The percentages of patients with of previous exposure to macrolides (14.7% vs. 5.5%, P <0.001) or amoxicillin (10.6% vs. 7.3%, P =0.006) were higher in patients with previous clarithromycin-based eradication failure. Conclusions: The H. pylori treatment protocol was not significantly modified despite the updates in the clinical guideline. There was only 1.4 percentage point increase in bismuth-based quadruple therapy as first-line eradication therapy even after the announcement of revised Korean guideline in 2013.

Cases of foreign body ingestion are frequently seen in gastroenterology. However, it is not common for the foreign body to be located in the submucosa, which obscures it from view, even during endoscopy. A 74-year-old woman visited the emergency room 10 days after swallowing an implant screw during an implant procedure at a dental clinic. Abdominal CT revealed a 14-mm-long radio-opa-que screw in the posterior wall of the proximal body of the stomach. On endoscopy, the screw was not observed in the stomach; how-ever, fluoroscopic examination revealed that it was located under the mucosa of the posterior wall of the proximal body of the stomach. The screw was grasped using alligator forceps and retrieved. There was no evidence of perforation on chest radiography. Herein, we present a case wherein a foreign body embedded under the mucosa was removed. (Korean J Helicobacter Up Gastrointest Res 2022 Aug 10. [Epub ahead of print])

Barrett’s esophagus (BE) is caused by metaplasia of squamous epithelium into columnar epithelium, mainly in the lower esophagus. Updates have been made in the etiology, diagnosis and treatment of BE since its first report as an ulcerative lesion in the lower esophagus. Columnar metaplasia of the lower esophagus has been reported as a result of gastroesophageal reflux, rather than genet-ic factors. When specialized intestinal metaplasia (SIM) is confirmed on biopsy, it is diagnosed as BE; otherwise, it is described as columnar line esophagus (CLE). Recent recommendations state that the following two conditions must be satisfied to diagnose BE: CLE with a length ≥ 1 cm proximal to the gastroesophageal junction, or SIM, with goblet cells confirmed on biopsy. BE is a key risk factor for esophageal adenocarcinoma. Early detection and treatment of BE, dysplasia, and early esophageal adenocarcinoma arising from BE has become a critical issue in the USA and Europe. The prevalence of BE in Korea is likely to increase because of the increasing prevalence of gastroesophageal reflux diseases. However, there are few reports on the diagnosis and treatment of BE in Korea. In this narrative review, important historical discoveries related to BE, the anatomical structures and endoscopic findings around the gastroesophageal junction required for diagnosing CLE and BE, and a brief review of the guidelines for the diagnosis and treatment of BE are summarized.

Benign esophageal strictures, characterized by fibrotic narrowing of the esophageal lumen, are frequently encountered in clinical practice. Benign esophageal strictures are associated with a multifactorial etiology and may occur across various age and population groups. Common causes of benign esophageal strictures include gastroesophageal reflux disease (peptic stricture), esophageal injury secondary to surgery (anastomotic strictures), radiotherapy, caustic agent ingestion, or endoscopic resection. Benign esophageal strictures are categorized into simple and complex types based on their size, area involved, surface features, extent of luminal narrowing, and margins. Esophageal strictures often present clinically with dysphagia and may lead to severe complications. Regardless of the underlying cause, therapy is aimed at relief of dysphagia and prevention of stricture recurrence. Benign esopha geal strictures are commonly treated using endoscopic balloon or bougie dilation, followed by disease-specific approaches to treat underlying inflammation. However, based on the underlying cause, the risk of recurrence of benign esophageal strictures is 10~30%. Therapeutic options for refractory or recurrent esophageal strictures include endoscopic incisional therapy, esophageal stent placement, or intralesional injection of steroids or mitomycin C. The pathophysiology of esophageal strictures is complicated, and thor-ough understanding and patient cooperation are important for optimal management. Physicians should familiarize themselves with the various dilation strategies available and their application for management of specific types of stenotic lesions. In this article, we review the evaluation and management of patients with esophageal strictures. (Korean J Helicobacter Gastrointest

Histamine H2 receptor antagonists (H2RAs) suppress gastric acid production by blocking H2 receptors in parietal cells. Studies have shown that proton pump inhibitors (PPIs) are superior to H2RAs as a treatment for acid-related disorders, such as peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD). PPIs reduce gastric acid production by irreversibly inhibiting the H+/K+ ATPase pump, and they also increase gastric emptying. Although PPIs have differing pharmacokinetic properties, each PPI is effective in managing GERD and PUDs. However, PPIs have some limitations, including short plasma half-lives, breakthrough symptoms (especially at night), meal-associated dosing, and concerns associated with long-term PPI use. Potassium-competitive acid blockers (P-CABs) provide more rapid and profound suppression of intragastric acidity than PPIs. P-CABs are non-inferior to lansoprazole in healing erosive esophagitis and peptic ulcers, and may also be effective in improving symptoms in patients with non-erosive reflux disease. Acid suppressive drugs are the most commonly used drugs in clinical practice, and it is necessary to understand the pharmacological properties and adverse effects of each drug.

Gastrointestinal (GI) prokinetic agents are drugs that increase GI motility and promote the movement of contents in the GI tract by amplifying and controlling the contraction of GI smooth muscle. Currently used prokinetics increase GI motility by acting as a dopamine D2 receptor antagonist (e.g., metoclopramide, domperidone, levosulpiride) and 5-HT4 receptor agonist (e.g., mosapride, prucalopride). Some prokinetics also have a cholinesterase inhibitory property (e.g., itopride), and herb-derived prokinetics (e.g., motilitone) affect multiple receptors. Depending on the type and distribution of receptors on which the prokinetics bind, the effect(s) may be regional or throughout the GI tract. Most prokinetics have been used for functional dyspepsia and gastroparesis because they mainly affect upper GI motility. However, prucalopride, a highly selective 5-HT4 receptor agonist, is used primarily to treat chronic constipation and pseudo-obstruction. Dopamine D2 receptor antagonists also inhibit the D2 receptor in the medulla oblongata chemoreceptor trigger zone; therefore, they can treat nausea and vomiting. However, short term use of dopamine D2 antagonists at an appropriate dose is recommended because of their potential for central nervous system side effects by penetrating the blood-brain barrier. It is necessary to know the mechanism of action, each clinical trial’s characteristics, and the side effects of prokinetics to obtain the best clinical outcomes. This article aims to summarize the results of clinical studies related to the impact of currently available prokinetic agents in Korea on GI motility.

This article aims to summarize the results of clinical studies related to the impact of currently available prokinetic agents in Korea on GI motility.","PeriodicalId":22895,"journal":{"name":"The Korean Journal of Helicobacter and Upper Gastrointestinal Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45844293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Antispasmodics are effective in reducing abdominal pain associated with visceral organs, bloating, and bowel habit changes and are commonly used as “on-demand therapy.” A relatively regular intake of antispasmodics may help patients with functional gastrointestinal disease exacerbation. Irritable bowel syndrome and functional dyspepsia are representative functional gastrointestinal diseases with abdominal pain and bloating as the main symptoms. Most of the clinical data on antispasmodics are obtained from studies on functional gastrointestinal diseases including irritable bowel syndrome. Antispasmodics can be safely used for prolonged periods without serious adverse effects; however, different antispasmodics have different anticholinergic potencies. Antispasmodics with strong anticholinergic effects should be prescribed with caution to patients with glaucoma or prostatic hypertrophy-induced dysuria and to those driving vehicles, operating machinery, or receiving other anticholinergic drugs in combination. Antispasmodics meeting US Food and Drug Administration guidelines for efficacy, those showing relatively consistent efficacy in different trials, and those with prokinetic effects are currently available. Many patients with upper gastrointestinal symptoms have overlapping functional gastrointestinal disorders and may require antispasmodic drugs. Alternatively, tricyclic antidepressant or ramosetron use can be considered in patients with irritable bowel syndrome. This review summarizes the clinical data and characteristics of antispasmodics, particularly those available in South Korea.
