Objectives: Adenosine triphosphate-binding cassette subfamily G member 2 (ABCG2) and CD133 are recognized stem cell markers of gastric cancer. Extensive research has examined the significance of these markers in different types of cancers and their impact on prognoses, linking them to unfavorable clinical outcomes in various tumors. However, the prognostic value of these markers for gastric cancer remains unclear. We investigated the expression of ABCG2 and CD133 and their relationship with clinical outcomes in gastric cancer.Methods: ABCG2 and CD133 expression levels were analyzed, using immunohistochemistry and tissue microarrays, in tumor samples from 459 patients who underwent surgical resections due to gastric cancer. ABCG2 and CD133 expression levels were defined by intensity and dichotomized as medians. The associations among the expression levels of these markers, disease severity, and patient survival were also determined.Results: In the 411 patients for whom we analyzed the expression levels of these markers, 74.9% and 80.5% were found to have high levels of ABCG2 and CD133, respectively. High expression levels of ABCG2 and CD133 were more commonly observed in well-differentiated (p<0.001 and p=0.004, respectively) and intestinal lesions (p<0.001 and p=0.002, respectively). High ABCG2 expression correlated with improved survival outcomes, whereas high CD133 expression was associated with poorer outcomes. Cox regression analysis confirmed that stage, high ABCG2 (overall survival [OS]: hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.41–0.91; p=0.015; recurrencefree survival [RFS]: HR, 0.55; 95% CI, 0.34–0.88; p=0.012), and CD133 expression (OS: HR, 1.59; 95% CI, 1.00–2.51; p=0.049; RFS: HR, 2.29; 95% CI, 1.21–4.34; p=0.011) were predictors of survival. A subgroup analysis indicated that ABCG2 expression was also associated with an improved RFS rate in patients who received systemic chemotherapy.Conclusions: High ABCG2 expression and low CD133 expression in tumors correlated with improved survival outcomes in post-resection patients with gastric cancer, suggesting their potential utility as prognostic biomarkers.

Anisakiasis is a zoonotic parasitic infection associated with consumption of raw fish or uncooked seafood. We report a rare case of suspected esophageal anisakiasis-induced dysphagia. A 66-year-old man patient without any medical history was admitted to our hospital for evaluation of acute dysphagia. Following intake of abalone sashimi for dinner, he experienced sudden difficulty with swallowing the day before his emergency department visit. He developed skin rash and pruritus throughout his body, shortly thereafter. He also had chest and upper abdominal pain and diarrhea. He had experienced similar symptoms after consumption of raw fish on two previous occasions. Dysphagia improved 9 days later. Gastroscopy performed after symptom onset showed small erosions and edematous mucosa in the mid esophagus. Abdominopelvic computed tomography (CT) showed distal esophageal wall thickening and small bowel obstruction with concomitant ascites. We suspected anisakiasis based on the following criteria: 1) Skin rash after the third episode of consumption of raw fish or seafood (anisakiasisspecific immunoglobulin E class 4). 2) CT-documented small intestinal obstruction and ascites. 3) Eosinophil-dominant fluid observed on ascitic fluid analysis. Therefore, it is reasonable to conclude that temporary dysphagia in this patient was attributable to esophageal anisakiasis associated with raw seafood consumption.

Patients with upper gastrointestinal tract cancers frequently develop severe malnutrition during treatment. Optimal nutritional management is imperative to enhance the efficacy of both chemotherapeutic and surgical interventions. In this article, various methods for nutritional screening and assessment, including a range of biochemical assays and decision-making frameworks relevant to clinical settings. We have described pre- and postoperative nutritional strategies and highlighted the established practical guidelines. Additionally, we investigated the key aspects of nutritional oversight during oncological treatment and emphasize the significance of a multidisciplinary approach that involves the services of physicians, dietitians, and nurses. We have outlined specific strategies to facilitate interprofessional collaboration in this setting.

Mixed neuroendocrine-nonneuroendocrine neoplasms (MiNENs) of the gastrointestinal tract, particularly gastric MiNENs are rare, and a gastric adenoma that occurs concomitant with a neuroendocrine carcinoma (and not gastric adenocarcinoma) is extremely rare. The clinicopathologic and pathogenetic features of MiNENs remain unclear, and treatment guidelines are currently unavailable. A 75-year-old man patient was referred to our hospital for management of a gastric adenoma. Endoscopy revealed an elevated mucosal lesion (10 mm×10 mm) at the greater curvature of the lower gastric body. The patient underwent endoscopic submucosal dissection for removal of the gastric neoplasm. Histopathological evaluation revealed mixed epithelial dysplasia, low and partly high grade and a neuroendocrine tumor (grade 1). Immunohistochemical analysis showed neoplastic cells with immunopositivity for CD56, synaptophysin, and INSM1, and Ki-67 showed 2.2%. Therefore, the patient was diagnosed with a low-grade gastric MiNEN. We present a rare case of gastric MiNENs (adenoma-neuroendocrine tumor) together with a literature review.

An increase in the volume of endoscopic procedures performed in recent times has led to increasing detection rates of asymptomatic gastrointestinal subepithelial tumors. However, accurate diagnosis and risk assessment of these tumors preoperatively is challenging. A 70-year-old man patient visited the emergency department for evaluation of melena. Emergency endoscopy revealed an ulcerated subepithelial tumor (8 cm in size) in the gastric cardia and fundus. Computed tomography and upper endoscopy performed at another hospital 6 months earlier were reviewed; the mass showed a significant increase in size (from 2 cm to 8 cm). The patient underwent surgical resection of the mass and was diagnosed with a high-risk gastrointestinal stromal tumor (GIST). In this article, we describe a rare case of a rapidly growing GIST at a rate significantly greater than commonly reported rates.

Obesity is a global health concern associated with a wide range of diseases, including diabetes, metabolic syndrome, fatty liver, and cardiovascular conditions. Recent studies highlight the significant role of gut microbiota in obesity. Research indicates notable changes in the composition and diversity of gut microbiota in individuals diagnosed with obesity. The gut microbiota participate in energy metabolism, lipid synthesis, and regulation of inflammation and therefore play a key role in the pathogenesis of obesity. Therapeutic approaches based on the use of probiotics, prebiotics, Akkermansia muciniphila, and fecal microbiota transplantation have shown promise in animal studies as useful strategies against obesity and metabolic syndrome. However, further research is warranted to conclusively establish the specific strains, dosages, and mechanisms underlying the effectiveness of these novel strategies against obesity in humans.

Objectives: Gastrointestinal cytomegalovirus (CMV) disease is a major contributor to mortality in immunocompromised patients. Few studies have discussed upper gastrointestinal CMV (UGICMV) disease in immunocompetent patients. We compared the clinical outcomes of UGI-CMV between immunocompromised and immunocompetent patients.Methods: This retrospective study included patients with UGI-CMV disease from five tertiary hospitals across Korea (2010– 2022). Patients’ clinical data and outcomes were recorded.Results: UGI-CMV was diagnosed in 54 patients; 27 (50.0%) had esophageal, 24 (44.4%) had gastric, and 3 patients (5.6%) had duodenal involvement. Patients’ median age was 64 years (interquartile range 53–75 years), and the most common comorbidities included hypertension (57.4%) and diabetes (38.9%). The predominant symptom was abdominal pain (46.3%), and the most common endoscopic finding was ulcers (70.4%). Antiviral treatment was administered to 31 patients, and 23 patients underwent observation without treatment. We investigated 32 immunocompromised (59.3%) and 22 immunocompetent (40.7%) patients and observed no intergroup differences in comorbidities and in laboratory and endoscopic findings. Immunocompromised patients had longer length of hospitalization (median 46.2 days vs. 20.0 days, p=0.001). However, treatment outcomes, including the need for intensive care unit admission and mortality did not significantly differ. The overall mortality rate was 13.0%; one patient from the immunocompromised group died of UGI-CMV disease. The treatment success rate was higher in immunocompromised patients who received antiviral therapy (p=0.011).Conclusions: UGI-CMV disease is not uncommon in immunocompetent patients, although symptoms are milder than those in immunocompromised patients. Our findings emphasize the importance of clinical vigilance for accurate diagnosis of CMV infection, particularly in susceptible symptomatic patients and highlight the need for active antiviral treatment for management of immunocompromised patients.

Percutaneous endoscopic gastrostomy (PEG) is the modality of choice for long-term enteral feeding in patients in whom oral intake is challenging. Compared with parenteral nutrition, gastrostomy feeding is the preferred choice for sustained nutritional support. Delivery of nutrients directly to the gastrointestinal tract and enhanced cellular immunity associated with this approach are clinically beneficial to patients. Endoscopic gastrostomy is favored for its high clinical success rates and economic advantages and is associated with minor discrepancies with regard to morbidity, mortality, and tube function compared with surgical gastrostomy. PEG procedures can be broadly classified into the pull- and push-types. Although PEG is a comparatively safe procedure, high risk of bleeding is a well-known complication of PEG placement, which necessitates prophylactic antibiotic therapy and careful periprocedural management in patients who receive antiplatelet and anticoagulant agents. Tube dislodgement, peristomal leakage, or infection following PEG placement may require tube replacement or removal. In this review, we investigated the concerns associated with early vs. delayed feeding in concordance with current guidelines. We also describe the indications for PEG tube insertion, post-procedural care strategies, and management of complications.
