Signet-ring cell carcinoma (SRCC) is a rare tumor that most commonly occurs in the stomach. Duodenal SRCCs are extremely uncommon and account for approximately 1% of duodenal adenocarcinomas. Although Brunner’s gland hyperplasia (BGH) is a benign duodenal condition, studies have reported several cases of adenocarcinoma originating in an area of BGH. We report a rare case of early-stage SRCC originating in an area of BGH that was successfully treated using endoscopic mucosal resection. Based on the mucin phenotype observed in this case, it is reasonable to conclude that SRCC originated from gastric metaplasia in the area of BGH. Although BGH is a benign condition, careful evaluation is warranted for early detection of combined neoplasms.

Esophageal perforation can lead to serious complications, and rapid diagnosis and treatment significantly affect the prognosis. Endoscopic vacuum-assisted closure (EndoVAC) therapy is widely accepted as a safe, well-tolerated, effective, versatile and practical procedure for the management of esophageal perforation in selected patients. We report the successful use of EndoVAC therapy for management of an esophageal perforation secondary to foreign body removal. A 56-year-old man presented to the emergency department for evaluation of chest pain after swallowing the plastic shell of a pill. Emergency endoscopy revealed an esophageal wall laceration (approximately 3 cm) and microperforation. The esophageal laceration and microperforation were limited to the mid-esophagus. The patient underwent EndoVAC therapy, which was repeated every 3–4 days for a total of six sessions over a period of 21 days. We observed improvement in the esophageal injury with granulation tissue formation during the fifth session. Subsequent follow-up evaluation, including esophagography and chest computed tomography confirmed complete healing of the esophageal injury. Following resumption of diet, the patienton a was discharged without any complications.

Mycoses refer to infectious diseases caused by fungi. Fungal infections are rare and mainly occur as opportunistic infections in immunocompromised patients. Candida species are the most common cause of mycosis; however, members of the order Mucorales or genus Aspergillus may also cause serious fungal infections in immunocompromised hosts. Fungal infections of the gastrointestinal (GI) tract can be asymptomatic or may present with abdominal pain, bloating, diarrhea, or GI bleeding. Although rare, thorough understanding of fungal infections of the upper GI tract encountered in real-world clinical settings can enable early diagnosis and prompt initiation of treatment to improve patient prognosis.

An acidic environment, gastric emptying, and abundant blood supply inhibit bacterial infection of the stomach. Helicobacter pylori can evade these defense mechanisms and is a well-known etiological contributor to chronic gastritis. Non-H. pylori bacterial infections such as acute phlegmonous gastritis, gastric syphilis, gastric tuberculosis, and gastric actinomycosis are uncommon and owing to their nonspecific findings, are diagnostically challenging in patients without a high index of clinical suspicion. Predisposition to bacterial infection is attributable to an increase in the prevalence of medical conditions and factors that precipitate immunosuppression, in addition to high rates of gastric mucosal injury associated with endoscopic procedures. Gastric bacterial infection negatively affects patients’ quality of life, increases the socioeconomic burden, and may occasionally be fatal. Therefore, physicians should be familiar with the endoscopic features and clinical manifestations of non-H. pylori bacterial infections of the stomach.

Objectives: Tegoprazan, a novel potassium-competitive acid blocker with rapid and effective antisecretory activity, was approved for the treatment of Helicobacter pylori infections in Korea in March 2020. However, real-world data regarding tegoprazan-based therapies are scarce. We compared the efficacies of tegoprazan- and lansoprazole-based triple therapies (TTs).Methods: Between March 2020 and February 2023, this study enrolled patients diagnosed with H. pylori infections who were prescribed either 14-day tegoprazan- or lansoprazole-based TTs as first-line treatments. Their medical records were retrospectively reviewed to compare H. pylori eradication rates and the rates of patient adherence to the recommended therapy.Results: A total of 670 patients diagnosed with H. pylori infections were prescribed 14-day TT regimens between March 2020 and February 2023 at Ilsan Paik Hospital (Goyang, Korea). Of those enrolled in the study, 64 received tegoprazan-based TT and 295 received lansoprazole-based TT as their first-line treatment. The H. pylori eradication rates for tegoprazan- and lansoprazole-based TTs were 76.6% and 75.6%, respectively, in the intent-to-treat population; the rates were 88.9% and 88.4%, respectively, in the per-protocol population (non-inferiority test, p=0.03 and p=0.01 in the respective populations). No significant differences were observed between the two groups with regards to treatment adherence rates (84.4% vs. 85.1%, p=0.78).Conclusions: As a first-line treatment for H. pylori eradication, 14-day tegoprazan-based TT demonstrated non-inferior efficacy compared with 14-day lansoprazole-based TT.

Objectives: Localized gastric Langerhans cell histiocytosis (LCH) characterized by abnormal proliferation of Langerhans cells in the stomach without systemic involvement, is rare; therefore, the clinical characteristics and outcomes of LCH remain unclear. We investigated the clinical characteristics and outcomes in patients diagnosed with localized gastric LCH and have also discussed treatment strategies for this rare disease.Methods: The study included seven patients diagnosed with localized gastric LCH at our hospital between September 1997 and December 2023. We retrospectively reviewed medical records and analyzed the clinicopathological characteristics and patient outcomes.Results: Endoscopically, localized gastric LCH appeared as a small erosion in the distal part of the stomach. Positron emission tomography-computed tomography revealed normal findings in 100.0% (4/4) of patients during pre-treatment workup. Immunohistochemical analysis using S-100 and CD1a showed immunopositive cells in all tested patients. Of the six patients who underwent follow-up, two (33.3%) showed metachronous recurrence at a location distinct from the initial site. However, all patients eventually showed spontaneous regression of the disease, and no gastric LCH-induced mortality was observed during follow-up.Conclusions: Careful and regular surveillance may be sufficient for patients with localized gastric LCH without systemic involvement.

Korea was a hotspot for parasitic infections until modern times. However, following economic development, improved health and hygiene and farming methods, and successful implementation of active deworming programs, human parasites are rare. Currently, medical and scientific advances have improved the survival rate of elderly and immunocompromised hosts, and immunosuppressants are widely administered for treatment, which may predispose patients to parasitic and various opportunistic infections. Furthermore, globalization has led to the entry of an increasing number of individuals from various countries into Korea, which increases the risk of transmission of parasites from foreign countries into Korea. However, parasitic diseases will tend to disappear in Korea, which may lead to reduced proficiency and diagnostic rate of existing stool tests, and new diagnostic methods tailored to Korea are unavailable. Currently, endoscopy is widely used as a standard method for gastrointestinal disease evaluation in Korea, and endoscopically detected parasites or parasite-induced abnormalities are useful to establish diagnosis in many cases. In this article, the author summarize the current status of endoscopic detection of parasitic diseases affecting the upper gastrointestinal tract.
