Background: A jejunal gastrointestinal stromal tumor (GIST) is a rare neoplasm of the gastrointestinal (GI) tract. Massive bleeding due to a jejunal GIST is a diagnostic and therapeutic challenge. It may be a life-threatening GIST complication that requires urgent intervention. Acute GI bleeding, which requires urgent surgical intervention, is a very rare clinical manifestation of GIST. A jejunal GIST with massive hemorrhage with coronavirus disease 2019 in a male patient in older age with many comorbidities has been not reported in the worldwide literature. Methods: In this case report, we present an 80-year-old man who was admitted to surgery due to abdominal pain, melena, and hematochezia for several hours. An upper endoscopy and colonoscopy were inconclusive. A multidetector contrast-enhanced computed tomography (CT) of the abdominal and pelvic cavity showed concentric irregular thickening in the distal jejunum. The histopathological finding showed a GIST measuring 6 cm with a mitotic index 2/50 high power fields. The patient’s hemodynamic condition deteriorated despite initial conservative treatment including a blood transfusion. Therefore, patient underwent the emergency surgery 24 hours after admission: partial jejunal resection with the tumor followed by primary end-to-end anastomosis. Results: The mass was removed completely. There were no surgical complications in the postoperative course. On the first postoperative day, a severe acute respiratory syndrome coronavirus 2 polymerase chain reaction test was performed due to a persistent dry cough, which yielded a positive result. After 14 days, the patient died due to pneumonia and circulatory failure. Conclusions: This case indicates that jejunal GIST can present as massive lower gastrointestinal bleeding and urgent surgery can successfully stop bleeding and save the patient’s life. The CT scan was the most effective investigation to find the source of GI bleeding in this case. Therefore, we suggest performing CT in patients with acute massive lower gastrointestinal bleeding when the source of bleeding is not visible on endoscopy, and urgent surgical jejunal resection to stop life-threatening bleeding caused by a jejunal GIST.

Background: The COVID-19-pandemic poses challenges to the medical system and especially to endoscopic staff and patients. National, European and International societies provided recommendations on how to safely perform endoscopic procedures during the current pandemic. Until now, the effect of the current pandemic on tertiary endoscopy centers has not been reported. Objective: The aim of this was to analyze the influence of the early SARS-CoV2-pandemic on endoscopic care and work flow in 2 European tertiary endoscopy units. Methods: Data from 2 tertiary endoscopy units (Katowice and Munich) were retrospectively collected during the early pandemic and compared to an equivalent pre-pandemic period. Data include procedures, complications, benchmarks, and influence on endoscopy training. Results: During the early pandemic, we noted a highly significant decrease (49.1%) in the overall number of all endoscopies with a significant increase in therapeutic procedures. Besides, there were no significant differences in the number of urgent endoscopic retrograde cholangiopancreatography or interventional endoscopic ultrasound procedures. The exceptional situation reduced endoscopic procedures performed by trainees significantly. Conclusions: The SARS-CoV2-pandemic halved the endoscopy service of 2 tertiary centers while maintaining an urgent therapeutic service. Recommended personal safety measures in endoscopy proved to be efficient and safe in preventing SARS-CoV2 infection of staff or spreading. Unnecessarily, the SARS-CoV2 pandemic prevented routine endoscopy training.

Pancreatic pseudocysts (PPCs) are frequent complications of acute and chronic pancreatitis, characterized by encapsulated collections of pancreatic fluid. Historically managed by open surgical approaches, treatment paradigms have significantly evolved with advancements in imaging and minimally invasive techniques. This review outlines the historical progression and current standards in PPC management, covering conservative, surgical, laparoscopic, and endoscopic interventions. Conservative management remains a valid first-line option for asymptomatic, stable pseudocysts, particularly in the absence of complications. Surgical techniques, once the mainstay, such as marsupialization and internal drainage procedures (cystogastrostomy, cystojejunostomy, and cystoduodenostomy), now serve as alternatives when less invasive methods fail. Laparoscopic approaches offer reduced morbidity and faster recovery, especially for complex or inaccessible PPCs. However, endoscopic drainage, particularly endoscopic ultrasound-guided transmural drainage using plastic or metal stents—especially lumen-apposing metal stents (LAMSs)—has become the preferred modality due to its efficacy, safety profile, and cost effectiveness. Emerging technologies, including robotic-assisted surgery and hybrid techniques, promise further refinement in PPC management. This review synthesizes current evidence and expert guidelines, providing a comprehensive overview of evolving strategies and future directions in the treatment of PPCs.

To investigate serum omentin and vaspin levels in cirrhotic patients; and to assess the relationship of these levels with hemostatic parameters, metabolic abnormalities, cirrhosis severity and etiology. Fifty-one cirrhotic patients (17 with portal vein thrombosis) were analyzed. Serum omentin and vaspin levels were measured with commercially available direct enzyme-linked immunosorbent assays (ELISAs). To assess platelet activity, the following tests were performed using a MULTIPLATE^®PLATELET FUNCTION ANALYZER: (1) an ADP-induced platelet activation test; (2) a cyclooxygenase dependent aggregation test (ASPI test); (3) a von Willebrand factor and glycoprotein Ib-dependent aggregation (using ristocetin) test (RISTO test); and (4) a test for thrombin receptor-activating peptide-6 induced activation of the thrombin receptor, which is sensitive to IIb/IIIa receptor antagonists. Omentin, but not vaspin, serum concentrations were significantly decreased in patients with portal vein thrombosis (PVT) (P = 0.01). Prothrombin levels were significantly increased in patients with PVT (P = 0.01). The thrombin receptor activating peptide (TRAP) test results were significantly lower in the PVT group (P = 0.03). No significant differences in adipokines serum levels were found regarding the etiology or severity of liver cirrhosis assessed according to the Child-Pugh or Model of End-Stage Liver Disease (MELD) scores. There was a significant increase in the TRAP (P = 0.03), ASPI (P = 0.001) and RISTO high-test (P = 0.02) results in patients with lower MELD scores. Serum omentin and vaspin levels were significantly down-regulated in patients without insulin resistance (P = 0.03, P = 0.02, respectively). A positive relationship between omentin and vaspin levels were found both when all of the patients were analyzed (r = 0.41, P = 0.01) and among those with PVT (r = 0.94, P < 0.001). Serum omentin levels are increased in patients without PVT. Cirrhosis origin and grade do not affect omentin and vaspin levels. The analyzed adipokines do not influence platelet activity.

Introduction: Gastric antral vascular ectasia (GAVE) is a rare vasculopathy that associates several diseases, most commonly liver cirrhosis. It usually presents as an occult gastrointestinal bleeding leading to profound iron deficiency anemia. We hypothesized that GAVE is local mucosal pathology dependent on genetic mechanisms, and the purpose of the study was to characterize miRNAs expression in gastric tissue of patients with cirrhosis and GAVE. Materials and methods: Thirteen patients with GAVE and cirrhosis and 35 healthy subjects were recruited. Microarray analysis and comparative microRNA study was done by quantitative polymerase chain reaction (qPCR). The microarray scores were grouped with use of the hierarchical clusterization analysis and miRNA target prediction was done with TargetScan 6.2 algorithm and Gene Ontology analysis (DIANA-miRPath). Results: Concentration of miR-3677 in GAVE-affected mucosa was higher by 72% in comparison with GAVE-free mucosa of patients with cirrhosis (33.7 vs. 35.6 PCR cycles; p < .001) and by 45% in comparison with normal mucosa (33.7 vs. 34.9 PCR cycles; p < .05). According to Gene Ontology analysis miR-3677 was related to angiopoietin-like protein 4 (ANGPTL4) gene. Conclusion: GAVE in liver cirrhosis is associated with increased expression of miR-3667 that may be linked with ANGPTL4 gene.
