Systematic strategies for preventing and treating esophagogastric variceal rebleeding (EVRB) are currently inadequate. This systematic review aimed to update this critical gap by searching contemporary studies from major guideline websites, databases, and professional associations focused on EVRB prevention in cirrhosis patients. Key findings highlight evaluation methods, risk management, preventive measures, health education, and follow-up strategies. Notably, a hepatic venous pressure gradient exceeding 18 mmHg is identified as a reliable predictor of gastroesophageal varices (GOV) rebleeding. Effective management of primary diseases is crucial, with methods including antiviral and anti-fibrotic therapies, alcohol avoidance, vaccination, and careful medication management. The combination of nonselective β-blockers (NSBBs) and endoscopic variceal ligation (EVL) is established as the gold standard for secondary EVRB prevention. For patients experiencing recurrent bleeding despite NSBBs and EVL, transjugular intrahepatic portosystemic shunt (TIPS) therapy is recommended. Surgical options, such as surgical shunt and devascularization, are advised for those unsuitable for endoscopic therapy or TIPS, particularly in Child-Pugh A and B patients unresponsive to treatment. Additionally, traditional Chinese medicine options, such as Fufang Biejia Ruangan Tablets, Fuzheng Huayu Capsules, and Anluo Huaxian Pills, have shown promise in improving hepatic fibrosis and GOV in cirrhotic patients. This review offers a comprehensive overview of current prevention and treatment strategies for EVRB, providing valuable insights for clinicians and healthcare professionals.

OBJECTIVES: To assess the efficacy and safety of pharmacological interventions for preventing upper gastrointestinal (GI) bleeding in people admitted to intensive care units (ICUs). DESIGN AND SETTING: Systematic review and frequentist network meta-analysis using standard methodological procedures as recommended by Cochrane for screening of records, data extraction and analysis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the certainty of evidence. PARTICIPANTS: Randomised controlled trials involving patients admitted to ICUs for longer than 24 hours were included. SEARCH METHODS: The Cochrane Gut Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and Latin American and Caribbean Health Science Information database (LILACS) databases were searched from August 2017 to March 2022. The search in MEDLINE was updated in April 2023. We also searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). MAIN OUTCOME MEASURES: The primary outcome was the prevention of clinically important upper GI bleeding. RESULTS: We included 123 studies with 46 996 participants. Cimetidine (relative risk (RR) 0.56, 95% CI 0.40 to 0.77, moderate certainty), ranitidine (RR 0.54, 95% CI 0.38 to 0.76, moderate certainty), antacids (RR 0.48, 95% CI 0.33 to 0.68, moderate certainty), sucralfate (RR 0.54, 95% CI 0.39 to 0.75, moderate certainty) and a combination of ranitidine and antacids (RR 0.13, 95% CI 0.03 to 0.62, moderate certainty) are likely effective in preventing upper GI bleeding.The effect of any intervention on the prevention of nosocomial pneumonia, all-cause mortality in the ICU or the hospital, duration of the stay in the ICU, duration of intubation and (serious) adverse events remains unclear. CONCLUSIONS: Several interventions seem effective in preventing clinically important upper GI bleeding while there is limited evidence for other outcomes. Patient-relevant benefits and harms need to be assessed under consideration of the patients' underlying conditions.

OBJECTIVES: To determine whether selected single nucleotide polymorphisms (SNPs) of genes encoding proteins responsible for the activation, transport, or metabolism of dabigatran and apixaban might be associated with a risk of gastrointestinal bleeding in a cohort of adult patients treated with these drugs. No previous study has focused specifically on the association with gastrointestinal bleeding. MATERIALS AND METHODS: Ninety-one patients treated with dabigatran or apixaban were genotyped for selected polymorphisms. The following polymorphisms were studied: ABCB1 gene rs1045642, rs4148738, rs1128503 and rs2032582; CES1 gene rs2244613, rs8192935 and rs2244614; and SULT1A1 gene rs9282861 and SULT1A2 gene rs1136703. Two groups divided by particular drugs and genotypes were compared in terms of the presence (bleeding group) or absence (nonbleeding group) of gastrointestinal bleeding. The genotype distribution was expressed via dominant and recessive models. RESULTS: In patients treated either with dabigatran or with apixaban, no evidence was found to support the association of gastrointestinal bleeding with any genotype for any of the studied SNPs. CONCLUSION: In both dabigatran- and apixaban-treated patients, no associations between the selected polymorphisms and gastrointestinal bleeding risk were found, however the results should be interpreted with caution because of the small cohort size.

BACKGROUND: Glomus tumors (GTs) are mesenchymal neoplasms that are typically benign. Gastric GTs are uncommon and occur mainly in the upper gastrointestinal tract. Malignant gastric GTs are extremely rare, constituting less than 1% of gastric tumors. Because their features are similar to those of other tumors found in the same gastrointestinal region, such as stromal tumors, leiomyomas, lymphomas, and lipomas, the diagnosis is challenging. CASE PRESENTATION: A 52-year-old male patient presented with fatigue and melena. The initial endoscopic examination did not locate any source of bleeding. Six months later, pan-gastroscopy, performed due to progressive microcytic anemia, revealed a 40 × 30 mm polypoid lesion with deep ulcerations; histopathological analysis confirmed that it was a gastric GT with expression of alpha-actin and cadherin 17 and a Ki-67 index of 20%. The patient delayed surgical therapy until his symptoms worsened. Laparoscopic sleeve resection revealed a 65 × 45 × 25 mm tumor, and secondary immunohistochemical analysis revealed extensive spread into the mucosa and subserosa. Focally, the tumor bulged into some large veins. Genetic examination with RNA isolation further supported the histopathological diagnosis of gastric GT with uncertain malignant potential. CONCLUSIONS: This case underscores the diagnostic challenges posed by gastric GTs because they are rare and their clinical features are similar to those of other gastric tumors. Thorough histopathological and molecular analysis is essential for an accurate diagnosis. Surgical intervention remains the primary therapeutic approach. This case also emphasizes the need for long-term follow-up due to the potential for recurrence and malignancy.

Chronic radiation proctitis, although relatively rare, can be the source of severe comorbidity in patients who had undergone prior radiotherapy for pelvic malignancy. Although current treatments for radiation proctitis include argon plasma coagulation, heater probe, bipolar neodymium/yttrium aluminum garnet (Nd: YAG) lasers, these interventions are often burdened by the frequent occurrence of rectal ulcerations and stenosis. Since radiofrequency ablation (RFA) is frequently used to ablate esophageal malignancy and pre-malignancy, we report the efficacy of RFA using through the scope system in two patients with rectal bleeding due to radiation proctitis. In both cases, the procedure was well-tolerated with hemostasis achieved after 1 or 2 sessions of RFA. Mucosal re-epithelialization was observed in areas of previous bleeding with no stenosis or ulceration observed at follow-up.

Meckel's diverticulum (MD) is one of the most common malformations of the gastrointestinal tract. Most cases are asymptomatic; clinical symptoms occur only in about 4% of patients, presenting as gastrointestinal bleeding, intestinal obstruction, inflammation, or perforation. Bleeding is most frequently observed in children under 2 years of age. Older patients tend to experience inflammatory complications. Here, we present the case report of a 17-year-old male patient with life-threatening acute gastrointestinal bleeding due to MD. Based on this case report, we performed a retrospective study of a small group of patients admitted to the Department of Pediatric Surgery and Traumatology, Third Faculty of Medicine, Charles University and Thomayer University Hospital in Prague (KDCHT FTN) between January 2012 and March 2023 with the primary or secondary diagnosis of MD.

Upper gastrointestinal bleeding (UGIB) in COVID-19 presents challenges in patient management. Existing studies lack comprehensive review due to varied designs, samples, and demographics. A meta-analysis can provide valuable insights into the incidence, features, and outcomes of UGIB in COVID-19. A comprehensive literature search was carried out using several databases. We considered all appropriate observational studies from all over the world. Mantel-Haenszel odds ratios and associated 95% confidence intervals (CIs) were produced to report the overall effect size using random effect models. Besides, Random effects models were used to calculate the overall pooled prevalence. Funnel plots, Egger regression tests, and Begg-Mazumdar's rank correlation test were used to appraise publication bias. Data from 21 articles consisting of 26,933 COVID-19 patients were considered. The pooled estimate of UGIB prevalence in patients admitted with COVID-19 across studies was 2.10% (95% CI, 1.23-3.13). Similarly, the overall pooled estimate for severity, mortality, and rebleeding in COVID-19 patients with UGIB was 55% (95% CI, 37.01-72.68), 29% (95% CI, 19.26-40.20) and 12.7% (95% CI, 7.88-18.42) respectively. Further, UGIB in COVID-19 patients was associated with increased odds of severity (OR = 3.52, 95% CI 1.80-6.88, P = 0.001) and mortality (OR = 2.16, 95% CI 1.33-3.51, P = 0.002) compared with patients without UGIB. No significant publication bias was evident in the meta-analysis. The results of our study indicate that UGIB in individuals with COVID-19 is linked to negative outcomes such as severe illness, higher mortality rates, and an increased risk of re-bleeding. These findings highlight the significance of identifying UGIB as a significant complication in COVID-19 cases and emphasise the importance of timely clinical assessment and proper treatment.

Hemobilia is a rare condition defined as bleeding in the biliary tract. The clinical presentation is variable. The typical manifestation consists of jaundice, upper gastrointestinal bleeding, and right upper quadrant abdominal pain. This set of symptoms is known as "Quincke's triad." It is present in only 22%-35% of cases. Post-traumatic hemobilia is an extraordinarily rare condition occurring in only 6% of the patients with hemobilia. In general, it occurs in less than 0.2% of patients with liver trauma. A delay in the development of bleeding after liver trauma is frequent. Early diagnosis is essential because massive bleeding into the biliary tract is a potentially life-threatening condition. We present a case of a patient with massive hemobilia developed 12 days after blunt abdominal trauma. Computed tomography angiography showed two pseudoaneurysms in hepatic segments V and VIII with contrast medium extravasation. We successfully performed digital subtraction angiography with selective transcatheter arterial embolization of the leaking segment VIII pseudoaneurysm. Embolization of the pseudoaneurysm in segment V was technically impracticable. Our article provides a review of the published literature focussing on the prevalence, diagnostics, and treatment of post-traumatic hemobilia.

Variceal bleeding belongs to the one of the complications of portal hypertension and is a life-threatening condition. A transjugular intrahepatic portosystemic shunt (TIPS) is indicated in case of failure of the pharmacological and endoscopic therapy, even if it is associated with complications. Stent migration to the heart, is a rare event which may cause perforation of the right cardiac chambers or damage to the tricuspid valve. However, it may not be a problem in some cases. There are two approaches to extraction - percutaneous or surgical. Leaving the stent in situ is possible, especially in polymorbid patients. Choosing an optimal approach often requires interdisciplinary cooperation.
