Role of Endoscopy in the Diagnosis, Grading, and Treatment of Portal Hypertensive Gastropathy and Gastric Antral Vascular Ectasia.

Portal hypertensive gastropathy (PHG) and gastric antral vascular ectasia (GAVE) are 2 distinct gastric vascular abnormalities that may present with acute or chronic blood loss. PHG requires the presence of portal hypertension and is typically associated with chronic liver disease, whereas there is controversy about the association of GAVE with chronic liver disease and/or portal hypertension. Distinguishing between GAVE and PHG is crucial because their treatment strategies differ. This review highlights characteristic endoscopic appearances and the clinical features of PHG and GAVE, which, in turn, aid in their appropriate management.

Resolution of gastric antral vascular ectasia following cessation of imatinib.

A female patient in her 80s presented with chronic iron-deficiency anaemia secondary to gastric antral vascular ectasia (GAVE), despite repeated endoscopic treatment. Her medical history was notable for chronic myeloid leukaemia, for which she took imatinib. Due to a possible association between imatinib and GAVE described in a small number of case reports, cessation of imatinib was trialled. This led to a significant improvement in the patient's anaemia and resolution of GAVE on repeat endoscopy. GAVE is an uncommon cause of gastrointestinal bleeding, the aetiology of which is uncertain. This report describes an approach to the differential diagnosis of chronic iron-deficiency anaemia and an overview of GAVE syndrome. It illustrates the benefit of broadening the differential when the diagnosis is uncertain and the utility of case reports in informing the differential diagnosis.

Upper gastrointestinal bleeding from gastric antral vascular ectasia following cocaine use: case presentation and review of literature.

Gastric antral vascular ectasia (GAVE), also known as "Watermelon stomach", is a rare cause of upper gastrointestinal bleeding (UGIB). It is characterized by an endoscopic appearance of flat red blood vessels traveling from the pylorus to the antrum. Patients often present with chronic blood loss resulting in iron deficiency anemia, or, less commonly, with acute gastropathy resulting in massive hemorrhage. The etiology of GAVE is unknown but the disorder has been more commonly observed in patients with cirrhosis, especially with portal hypertension, as well as in those with systemic sclerosis and other connective tissue disease. There is no definitive cure for GAVE, but the condition can be managed with a variety of endoscopic techniques, including heater probes, bipolar probes, plasma coagulators, laser therapy, and radiofrequency ablation. In rare cases, patients also require blood transfusions. Here we present an interesting case of upper GI bleeding resulting in symptomatic anemia in a 69-year-old female patient with GAVE following cocaine use. The patient was initially admitted for fatigue and shortness of breath and required multiple units of pRBCs. She was also found to have a urine drug screen positive for cocaine. Following stabilization, she underwent endoscopy which revealed the characteristic "watermelon stomach" appearance consistent with GAVE syndrome. The patient was discharged on an oral proton-pump inhibitor with instructions to follow-up outpatient with Gastroenterology. This case is presented as an example of a risk factor for acute exacerbation of a rare cause of UGIB. This patient presentation also represents an example of the importance of strict follow-up for those with risk factors for exacerbation of chronic GI conditions.

Ectasia vascular antral gastrica (GAVE) / Gastric antral vascular ectasia (GAVE)

La ectasia vascular antral gástrica (GAVE) ha sido reconocida como una de las causas importantes de hemorragia gastrointestinal oculta y oscura. El diagnóstico generalmente se realiza en función de los rasgos endoscópicos característicos, incluida la fila longitudinal de rayas planas y rojizas que irradian desde el píloro hacia el antro que se asemejan a las rayas de una sandía (Watermelon). Estas apariencias, pueden ser fácilmente malinterpretadas como una gastritis de moderada a severa. El diagnóstico del síndrome GAVE en pacientes con enfermedad renal o hepática suele ser problemático porque hay causas más frecuentes de hemorragia gastrointestinal en estas enfermedades como, por ejemplo, malformaciones vasculares, enfermedad ulcerosa péptica, várices esofágicas o gástricas y úlceras colónicas y rectales que eclipsan al síndrome GAVE. Creemos que el tratamiento quirúrgico es una modalidad cuando los diferentes métodos, no pudieron tratar de solucionar esta patología del GAVE. Probablemente en nuestro medio necesitamos más sospecha clínica de esta patología, como así mismo mayor experiencia en los tratamientos endoscópicos de tipo terapéuticos. Ante la falla de estos métodos, la cirugía , ya sea laparoscópica o convencional siguen teniendo lugar en la resolución de estos pacientes con patología poco común.

Gastric antral vascular ectasia (Gave) has been recognized as one of the important causes of hidden and dark gastrointestinal hemorrhage. The diagnosis is generally performed based on the characteristic endoscopic features, including the longitudinal row of flat and reddish stripes that radiate from the pylorus to the antrum that resemble the stripes of a watermelon (watermelon). These appearances can be easily misunderstood as moderate to severe gastritis. The diagnosis of the Gave syndrome in patients with renal or hepatic disease is usually problematic because there are more frequent causes of gastrointestinal bleeding in these diseases such as vascular malformations, peptic ulcerative disease, esophageal or gastric veins and colonic and rectal ulcers that eclipsan al Gave syndrome. We believe that surgical treatment is a modality when the different methods could not try to solve this pathology of the Gave. Probably in our environment we need more clinical suspicion of this pathology, as well as more experience in therapeutic endoscopic treatments. Given the failure of these methods, surgery, whether laparoscopic or conventional continue to take place in the resolution of these patients with unusual pathology.

Successful treatment of refractory Gastric Antral Vascular Ectasia (GAVE) in a cirrhotic patient with transcatheter arterial embolisation in a tertiary care facility in Pakistan: A case report.

Gastric antral vascular ectasia (GAVE) is a rare but important cause of upper gastrointestinal bleeding that may present with refractory anaemia or overt gastrointestinal bleeding requiring multiple admissions and resuscitation. Although endoscopic therapies are considered first line treatment for the management of refractory gastric antral vascular ectasia, angiographic embolisation of the culprit vessel(s) may emerge as an effective and safe treatment modality in the near future. Here, we present the case of a middle-aged gentleman with refractory gastric antral vascular ectasia, who was not responding to repeated sessions of Argon Plasma Coagulation (APC) and was successfully treated with trans-catheter arterial embolisation of gastro-duodenal artery.

Endoscopic treatment of gastric antral vascular ectasia in real-life settings: Argon plasma coagulation or endoscopic band ligation?

OBJECTIVE: The efficacy of argon plasma coagulation (APC) on gastric antral vascular ectasia (GAVE) may be impaired over time and depends greatly on the application settings. Endoscopic band ligation (EBL) may be an alternative, but study on its efficacy is limited. This study aimed to evaluate and compare the clinical efficacy of APC and EBL in treating GAVE. METHODS: Changes in the need for blood transfusion, number of treatment sessions and hospitalizations were retrospectively assessed in 63 transfusion-dependent patients with GAVE (mean age: 67.1 y, 54.0% female) treated with either APC or EBL (45 and 18 patients, respectively) in four tertiary endoscopic centers. RESULTS: Both methods substantially increased hemoglobin levels and decreased patients' need for a transfusion (22.0 ± 4.0 g/L and -5.62 ± 2.30 units of packed red blood cells [RBC] with APC, and 27.4 ± 6.1 g/L and -4.79 ± 2.46 units of packed RBC with EBL), without a significant statistical difference between the methods. However, fewer EBL sessions were required both for the cessation of need for a transfusion compared with those for the resolution of GAVE lesions (0.90 ± 0.10 vs 1.69 ± 0.31, P = 0.028). CONCLUSIONS: Both APC and EBL are effective in GAVE treatment. EBL may be superior in terms of number of treatment sessions, but not in its influence on hemoglobin level and need for transfusion. Further prospective studies with large, homogeneous sample size and standardized APC settings are needed.

Portal Hypertension and Chronic Kidney Disease Significantly Increase the Risk of Early Unplanned Readmissions in GAVE- Related Admissions.

BACKGROUND AND AIMS: Gastric antral vascular ectasia (GAVE) is an uncommon cause of non-variceal upper gastrointestinal bleeding that is characterized by dilation of blood vessels in the antrum of the stomach. Various co-morbidities are associated with the development of GAVE, but the impact of co-morbidities on unplanned GAVE readmissions is unclear. The aim of this study was to assess the national incidence, 30-day mortality rate, and 30-day readmissions related to GAVE. Secondary outcomes were evaluation of predictors of early readmission, hospital length of stay (LOS) and total hospitalization charges. METHODS: Using the 2016 National Readmission Database, we analyzed discharges for GAVE. ICD-10 CM codes were utilized to identify associated comorbidities and inpatient procedures during the index admission. 30-day readmissions were identified for GAVE. Secondary measures of outcomes including LOS and hospitalization charges were also calculated. Risk factors for early readmission were also evaluated using multivariate analysis to adjust for confounders. RESULTS: A total of 18,375 index admissions for GAVE were identified. 20.49% (n=3,720) of the discharged patients were readmitted within 30 days. 30-day mortality of GAVE-related admissions was 1.82% (n=335). Early readmissions accounted for 20,157 hospital days along with $189 million in hospitalization costs. Multivariate analysis revealed that the presence of portal hypertension (OR 1.63; 95% CI 1.37-1.93; p=0.0001) and chronic kidney disease (CKD) (OR 1.62, 95% CI 1.44-1.82; p<0.0001) significantly increased the odds of early readmission. CONCLUSIONS: Our analysis demonstrates that the overall 30-day mortality rate of GAVE-related admissions is relatively low, but the 30-day readmission rate is significantly high. Patients with comorbid CKD and portal hypertension have a significantly higher risk of readmission. Further studies are required to determine if therapeutic interventions such as argon plasma coagulation or radiofrequency ablation during the index admission may prevent readmissions in these specific subgroups.

Gastric antral vascular ectasia in systemic sclerosis: Where do we stand?

Gastric antral vascular ectasia (GAVE) continues to be a challenge in both diagnosis and treatment. GAVE has a diverse group of associations and presumed causes, including cirrhosis, chronic renal failure and autoimmune connective tissue diseases. However, in most occasions, the management plan of GAVE itself is the same whatever the underlying disease by using Argon plasma coagulation (APC). Herein, we will discuss three cases of systemic sclerosis-associated GAVE presenting with either acute or chronic gastrointestinal bleeding showing variable responses to APC. Anemia and telangiectasia may be the first striking presentation of systemic sclerosis (SSc). Renal artery stenosis, aortic stenosis, widespread cutaneous and mucosal telangiectasia and hypertension seem to be associated with poor prognosis and should prompt rapid intervention and careful follow-up. Moreover, the hunt for molecular underpinnings of the broad array of vascular lesions in SSc has to include von Willebrand factor and endoglin. Eventually, we will review the recent alternatives that can be effective in SSc-GAVE, such as band ligation, hematopoietic stem cells transplantation and immunotherapy.

Thulium laser in interventional endoscopy: animal and human studies.

Background and study aims The thulium laser system (TLS) is an emerging surgical tool. The 2-µm wavelength provides a confined coagulation depth (0.2 - 0.4 mm) to reduce the potential for inadvertent injuries. For the first time ever, we assessed TLS feasibility for endoscopic hemostasis ex vivo in pigs. In addition, we performed the first in vivo hemostatic treatments in humans. Patients and methods Tissue damage induced by TLS using different settings and optical fibers was compared to that from argon plasma coagulation (APC) in established ex vivo animal models. Three consecutive patients with complex nonvariceal upper gastrointestinal bleedings were treated and followed up. Results No deep submucosal injury was observed in animal models. The TLS showed a progressive penetration depth with increased power outputs and tissue exposures but very limited vertical tissue injury (0.1 - 2.0 mm) and lateral spreading damage (0.1 - 0.3 mm and 0.2 - 0.7 mm using the 365-µm and 550-µm fibers, respectively). In vivo, endoscopic hemostasis with TLS was always successful without complications. Conclusions The TLS has proven to be very precise and easy to use. This novel technique appears to be a promising tool for advanced interventional endoscopy.

Imatinib-induced Gastrointestinal Vascular Ectasia in a Patient with Advanced GIST: Case Report and Literature Review.

BACKGROUND: Imatinib is generally well tolerated in the treatment of advanced gastrointestinal stromal tumors (GIST). Gastrointestinal vascular ectasia (GIVE) and gastric antral vascular ectasia (GAVE), while rare, are significant under-reported complications of imatinib therapy. CASE REPORT: We present one patient with GIVE complicating imatinib therapy with a literature review of this rare side-effect. RESULTS: A 68-year-old woman was diagnosed with advanced GIST, wild-type CKIT. After 3 months of treatment with imatinib, she had partial response. However, she was diagnosed with GAVE and, later, also with GIVE. During her 3-year imatinib treatment, she suffered from severe anemia and required blood transfusions. Conservative treatments were not helpful and the ectatic lesions resolved only with cessation of imatinib. CONCLUSION: This confirms a causal relationship between GIVE and imatinib. GIVE and GAVE should be considered possible causes of anemia and upper gastrointestinal bleeding in patients receiving imatinib therapy.

Gastrointestinal Issues in Liver Disease.

Gastrointestinal (GI) complications of cirrhosis are frequent in patients who require intensive care support and are often the primary indication for intensive care unit (ICU) admission. Perhaps the most worrisome GI complication for the intensivist is variceal hemorrhage. Bleeding from esophageal or gastric varices represents a life-threatening event for cirrhotic patients and provides management challenges for the ICU team. Nonvariceal GI bleeding, impaired GI motility, and malnutrition also provide significant challenges for the intensivist. This article reviews GI issues that present in critically ill cirrhotic patients and their management in the acute setting.

Alternativas terapéuticas para el manejo de la ectasia vascular gástrica antral (GAVE) / Alternatives for the treatment of gastric antral vascular ectasia (GAVE)

Gastric antral vascular ectasia is an unusual cause of upper gastrointestinal bleeding. The most frequent clinical presentation is iron deficiency anemia in a female patient older than 60 years. A third of patients have liver cirrhosis or a connective tissue disease, especially those related to Raynaud’s syndrome and scleroderma. The severity of this condition is variable, in some cases iron supplements are enough, while in other transfusion requirements are permanent. Currently the therapies most frequently reported in literature are argon plasma coagulation, radiofrequency ablation and endoscopic band ligation of antral mucosa. This article aims to review the available evidence for the management of this condition.

La ectasia vascular gástrica antral es una causa infrecuente de hemorragia digestiva alta cuya forma de presentación más habitual es la anemia ferropriva en una mujer mayor de 60 años. Un tercio de los pacientes tiene antecedente de cirrosis hepática o enfermedades del tejido conectivo relacionadas al síndrome de Raynaud o esclerodermia. El compromiso es de intensidad variable, sin embargo, en casos graves los pacientes pueden requerir transfusiones en forma permanente. En la actualidad las terapias más frecuentemente reportadas en la literatura son la termocoagulación con argón plasma, la ablación con radiofrecuencia y la ligadura de mucosa antral con bandas elásticas. El objetivo principal de este artículo es revisar la evidencia disponible para el manejo de esta condición.
