Curative effects of bipolar electrocoagulation for gastric antral vascular ectasia (with video) / 中华消化内镜杂志

To evaluate the efficacy and feasibility of bipolar electrocoagulation in the treatment of gastric antral vascular ectasia(GAVE). Six patients with GAVE who underwent gastroscopy and bipolar electrocoagulation between January 2018 and December 2019 in the Affiliated Hospital of Medical School of Ningbo University were included in the study.The operation and clinical response were observed. All the 6 patients underwent bipolar electrocoagulation successfully. The mean operation time was 32 min (range 25-45 min). Mean number of sessions required for eradication of GAVE was 1.17. No severe complications related to endoscopic treatment occurred. There was no recurrence of GAVE at a mean time of 10.8 months (range 2-25 months) of follow-up. Stabilization of hemoglobin levels and decrease in blood transfusion requirements along with endoscopically complete or near-complete eradication of GAVE were observed in all patients during the follow-up.Bipolar electrocoagulation in the treatment of GAVE is effective, safe, and simple.

Endoscopic Features of Upper Gastrointestinal Tract in Patients with Systemic Sclerosis Compared to the Healthy Control

OBJECTIVE: To characterize the endoscopic features of upper gastrointestinal tract in patients with systemic sclerosis (SSc) compared with those in the healthy controls. METHODS: Data on esophagogastroduodenoscopy (EGD) in 180 patients with SSc (SSc group) were compared with that from the 181 age- and sex-matched healthy control who underwent EGD for routine check-up (control group). Clinical data of participants at the time of EGD (defined as baseline) were collected from electric medical record. Endoscopic findings were evaluated by two experts with blinded to their clinical features. Primary outcome of the study was prevalence of each endoscopic lesion between the two groups. RESULTS: The mean±standard deviation age and disease duration in the SSc group at baseline were 55.3±11.8 and 2.9±3.7 years, respectively. Compared to the control group, SSc group more frequently showed reflux esophagitis (32.8% vs. 9.4%, p < 0.001). In contrast, prevalence of atrophic gastritis was significantly lower in the SSc group (8.3% vs. 29.3%, p < 0.001). This result was consistent in the multivariable analysis where patients' age and concomitant proton pump inhibitor use were adjusted. There was no case of gastric antral vascular ectasia (GAVE) in both groups. However, 29 (16.1%) patients in SSc group showed a clinically significant anemia (hemoglobin < 10 mg/dL), with none of the endoscopic features showed significant associations with the outcome. CONCLUSION: Patients with SSc showed significantly lower prevalence of atrophic gastritis. There was no case of GAVE, which suggests that clinical phenotype of the SSc could be different according to the ethnicity or geographic region.

Elevated Gastric Antrum Erosions in Portal Hypertension Patients: Peptic Disease or Mucosal Congestion? / 대한소화기학회지

BACKGROUND/AIMS: Portal hypertension (PH) is a syndrome characterized by chronic increase in the pressure gradient between the portal vein and inferior vena cava. Previous studies have suggested an increased frequency of antral elevated erosive gastritis in patients with PH, as well as an etiologic association; however, there has not been any histological evidence of this hypothesis to date. Our aim was to evaluate the histological features found in elevated antral erosions in patients with portal hypertension. METHODS: Sixty-nine patients were included; 28 with and 41 without PH. All patients underwent endoscopy, and areas with elevated antral erosion were biopsied. RESULTS: In the PH group, 24 patients had inflammatory infiltration with or without edema and vascular congestion, and 4 patients had no inflammation. In the group without PH, all patients showed inflammatory infiltration of variable intensity. There was no statistical significance between the two groups in the presence of Helicobacter pylori. There as a histological similarity between the two groups, if PH patients without inflammation were excluded; however, more edema and vascular congestion were observed in the PH group (p=0.002). CONCLUSIONS: The findings show that elevated antral erosions in patients with PH have more evident edema and vascular congestion in addition to lymphocytic infiltration.

Erythropoietin resistance in end-stage renal disease patient with gastric antral vascular ectasia / Resistência à eritropoetina em paciente com IRC e ectasia vascular gástrica

Abstract We observed a case of recombinant human erythropoietin resistance caused by Gastric Antral Vascular Ectasia in a 40-year-old female with ESRD on hemodialysis. Some associated factors such as autoimmune disease, hemolysis, heart and liver disease were discarded on physical examination and complementary tests. The diagnosis is based on the clinical history and endoscopic appearance of watermelon stomach. The histologic findings are fibromuscular proliferation and capillary ectasia with microvascular thrombosis of the lamina propria. However, these histologic findings are not necessary to confirm the diagnosis. Gastric Antral Vascular Ectasia is a serious condition and should be considered in ESRD patients on hemodialysis with anemia and resistance to recombinant human erythropoietin because GAVE is potentially curable with specific endoscopic treatment method or through surgical procedure.

Resumo Observou-se um caso de resistência à eritropoetina recombinante humana causada por Ectasia Vascular Antral Gástrica em uma mulher de 40 anos de idade, com doença renal terminal em hemodiálise. Alguns fatores associados, tais como a doença autoimune, hemólise, doenças cardíacas e hepáticas foram descartados no exame físico e exames complementares. O diagnóstico é baseado na história clínica e aspecto endoscópico de estômago em melancia. Os achados histológicos são proliferação fibromuscular e ectasia capilar com trombose microvascular da lâmina própria. No entanto, esses achados histológicos não são necessários para confirmar o diagnóstico. Ectasia Vascular Antral Gástrica é uma condição séria e deve ser considerada em pacientes com insuficiência renal terminal em hemodiálise com anemia refratária e resistência à eritropoetina humana recombinante porque é potencialmente curável com o método de tratamento endoscópico específico ou através de procedimento cirúrgico.

Thalidomide induced xerosis: an unwanted reaction.

A 59-year-old male exhibited anemia for evaluation. Endoscopy was diagnostic of gastric antral vascular ectasia. He was given a trial of thalidomide after informing about the adverse effects. After starting thalidomide at 100 mg/day, his hemoglobin (Hb) improved. Post 1 month of therapy his Hb normalized, but he developed xerosis. He was given symptomatic treatment, but did not improve. Thalidomide was suspected to cause xerosis, it was discontinued for a month and post-discontinuation of drug he is symptom free for past 8 months. This paper reports a rare case of thalidomide induced xerosis with dermatological and neurological involvement.

Management of portal hypertensive gastropathy and other bleeding

A major cause of cirrhosis related morbidity and mortality is the development of variceal bleeding, a direct consequence of portal hypertension. Less common causes of gastrointestinal bleeding are peptic ulcers, malignancy, angiodysplasia, etc. Upper gastrointestinal bleeding has been classified according to the presence of a variceal or non-variceal bleeding. Although non-variceal gastrointestinal bleeding is not common in cirrhotic patients, gastroduodenal ulcers may develop as often as non-cirrhotic patients. Ulcers in cirrhotic patients may be more severe and less frequently associated with chronic intake of non-steroidal anti-inflammatory drugs, and may require more frequently endoscopic treatment. Portal hypertensive gastropathy (PHG) refers to changes in the mucosa of the stomach in patients with portal hypertension. Patients with portal hypertension may experience bleeding from the stomach, and pharmacologic or radiologic interventional procedure may be useful in preventing re-bleeding from PHG. Gastric antral vascular ectasia (GAVE) seems to be different disease entity from PHG, and endoscopic ablation can be the first-line treatment.

Ligadura endoscópica, una nueva opción terapéutica para la ectasia vascular antral: presentación de dos casos clínicos / Endoscopic band ligation, for gastric antral vascular ectasia: Report of two cases

Gastric antral vascular ectasia is an uncommon cause of chronic anemia, occasionally associated with cirrhosis. The most accepted therapy is argon plasma coagulation (APC), however there are refractory cases. We report two females with cirrhosis, aged 60 and 72 years, in whom management with APC was insufficient and in whom the need for hospital admissions and transfusions were reduced using the technique of endoscopic band ligation.

Gastric antral vascular ectasia with aortic stenosis: Heydes syndrome.

Gastric antral vascular ectasia (GAVE) is a well-recognized albeit rare cause of gastro-intestinal (GI) bleeding. It classically presents in an elderly female as iron-deficiency anemia due to chronic blood loss. The association of GI blood loss with aortic stenosis (AS) has been popularized as Heydes syndrome (HS). We report a case of an elderly woman presenting as iron-deficiency anemia subsequently diagnosed with HS.

Portal Hypertensive Gastropathy and Gastric Antral Vascular Ectasia / 대한소화기학회지

Portal hypertensive gastropathy (PHG) is a term used to define the endoscopic findings of gastric mucosa with a characteristic mosaic-like pattern with or without red spots, and a common finding in patients with portal hypertension. These endoscopic findings correspond to dilated mucosal capillaries without inflammation. The pathogenesis of PHG in not well known, but portal hypertension and some humoral factors seem to be crucial factors for its development. Pharmacological (e.g. propranolol), or interventional radiological (such as transjugular intrahepatic portosystemic shunt) procedures may be useful in preventing re-bleeding from PHG. The classic features of gastric antral vascular ectasia (GAVE) syndrome include red, often haemorrhagic lesions predominantly located in the gastric antrum which can result in significant blood loss. Although the pathogenesis of GAVE is not clearly defined, it seems to be a separate disease entity from PHG, because GAVE generally does not respond to a reduction of portal pressures. Endoscopic ablation (such as argon plasma coagulation) is the first-line treatment of choice. This review will focus on the incidence, clinical importance, etiology, pathophysiology, and treatment of PHG and GAVE syndrome in the setting of portal hypertension.

Two Cases of Rectal Vascular Ectasia in Patients with Liver Cirrhosis and Who Were Treated by Argon Plasma Coagulation / 대한소화기내시경학회지

The term "vascular ectasia" is defined to include angiodysplasia, gastric antral vascular ectasia (GAVE) and telangiectasis, and these are the leading causes of acute or chronic gastrointestinal bleeding. We describe here the first 2 Korean cases of GAVE with rectal vascular ectasia in patients with liver cirrhosis. A 70-year-old woman was admitted to the hospital with hematochezia. The finding on endoscopy showed diffuse nonconfluent spots with oozing bleeding on the antrum and several vascular spots with oozing bleeding on the rectum. The lesions were successfully treated by argon plasma coagulation (APC). We report on another case of rectal vascular ectasia in a patient with liver cirrhosis. A 77-year-old man was admitted to the hospital with hematochezia. The findings on colonoscopy showed diffuse vascular spots with oozing bleeding on the rectum. The lesions were successfully treated by APC. These two patients have had no bleeding since their treatment, and they are currently being evaluated by follow-up studies at the outpatient department.

Watermelon stomach: clinical aspects and treatment with argon plasma coagulation / Ectasia vascular do antro gástrico ("watermelon stomach"): aspectos clínicos e tratamento com coagulação com plasma de argônio

BACKGROUND: Gastric antral vascular ectasia is a disorder whose pathogenetic mechanism is unknown. The endoscopic treatment with argon plasma coagulation has been considered one of the best endoscopic therapeutic options. AIM: To analyze the endoscopic and clinical features of gastric antral vascular ectasia and its response to the argon plasma coagulation treatment. PATIENTS AND METHODS: Eighteen patients were studied and classified into two groups: group 1 - whose endoscopic aspect was striped (watermelon) or of the diffuse confluent type; group 2 - diffuse spotty nonconfluent endoscopic aspect. RESULTS: Group 1 with eight patients, all having autoimmune antibodies, but one, whose antibodies were not searched for. Three were cirrhotic and three had hypothyroidism. All had gastric mucosa atrophy. In group 2, with 10 patients, all had non-immune liver disease, with platelet levels below 90.000. Ten patients were submitted to argon plasma coagulation treatment, with 2 to 36 months of follow-up. Lesions recurred in all patients who remained in the follow-up program and one did not respond to treatment for acute bleeding control. CONCLUSION: There seem to be two distinct groups of patients with gastric antral vascular ectasia: one related to immunologic disorders and other to non-immune chronic liver disease and low platelets. The endoscopic treatment using argon plasma coagulation had a high recurrence in the long-term evaluation.

RACIONAL: "Watermelon stomach" ou ectasia vascular do antro gástrico é uma doença de etiopatogenia desconhecida. O tratamento endoscópico através da coagulação com plasma de argônio é considerado uma das melhores opções terapêuticas. OBJETIVO: Analisar os aspectos clínicos e endoscópicos da ectasia vascular do antro gástrico e a resposta ao tratamento com coagulação com plasma de argônio. PACIENTES E MÉTODOS: Dezoito pacientes foram estudados e classificados em dois grupos: grupo I - oito pacientes que exibiam ectasia vascular do antro gástrico de aspecto difuso confluente ou estriado. Grupo II - 10 pacientes que apresentavam aspecto difuso pontilhado não-confluente. RESULTADOS: Todos os pacientes do grupo I apresentavam auto-anticorpos, exceto um paciente no qual não foi pesquisado. Três eram cirróticos, três tinham hipotireoidismo e todos apresentavam gastrite atrófica. No grupo II, todos tinham doença hepática não-autoimune, com plaquetas menores que 90.000. Dez pacientes foram submetidos a tratamento com coagulação com plasma de argônio, com 2 a 36 meses de seguimento. A ectasia vascular do antro gástrico recorreu em todos os pacientes que continuaram em acompanhamento e um paciente não respondeu ao tratamento para controle de sangramento agudo. CONCLUSÃO: Observou-se a existência de dois grupos distintos de pacientes com ectasia vascular do antro gástrico: um grupo associado a distúrbios imunológicos e outro com doença hepática não auto-imune e plaquetopenia. O tratamento com coagulação com plasma de argônio apresentou alta recurrência das ectasias vasculares.

Tratamento endoscópico de lesões sangrantes do trato gastrointestinal por meio de eletrocoagulação com argônio / Endoscopic treatment of bleeding lesions of the gastrointestinal tract by argon plasma coagulation

Introdução e objetivos: A eletrocoagulação com argônio (APC) é um método térmico de não-contato que pode ser utilizado como alternativa ao laser em endoscopia. Um amplo espectro de indicações têm sido propostas para tratamento através de APC, desde a introdução do uso em endoscopia, em 1991. O objetivo deste estudo é avaliar a eficácia do uso do APC na hemostasia endoscópica de lesões sangrantes do esôfago, estômago, duodeno, cólon e reto. Metodologia: Um total de 22 pacientes consecutivos (14M/8F, média de idade 66,7 anos) foram submetidos ao tratamento com APC entre 1998 e fevereiro de 2002. As causas de sangramento incluíam retite actínica (12 pacientes), ectasia vascular do antro gástrico (GAVE) ­ watermelon stomach (6 pacientes), angiodisplasias de esôfago, estômago e cólon (2 pacientes), gastrite actínica (1 paciente) e síndrome de Osler-Weber-Rendu (1 paciente). Resultados: Um total de 49 sessões foram realizadas (média de 2,2 sessões por paciente). Sucesso no tratamento endoscópico foi obtido em 18 pacientes (85,8%). Complicações foram observadas em 3 pacientes: 2 apresentaram dor local após as sessões de APC e um paciente desenvolveu estenose retal tratada com sucesso em uma sessão de dilatação endoscópica. Não houve mortalidade relacionada ao método. Conclusões: APC é um método seguro, efetivo, de relativo baixo custo e boa aceitação pelos pacientes para o tratamento de lesões sangrantes do trato gastrointestinal. Deve, portanto, ser considerado método de primeira escolha no tratamento dessas afecções (AU)

Background and aims: Argon plasma coagulation (APC) is an innovative non-touch electrocoagulation technique. A broad spectrum of indications has been proposed for APC since its introduction into endoscopy in 1991. The aim of this study is to evaluate the efficacy of utilizing APC in the endoscopic hemostasis of bleeding lesions of the esophagus, stomach, duodenun, colon and rectum. Methodology: A total of 22 consecutive patients (14M/ 8 F, mean age 66.7 years) underwent APC treatment between 1998 and february 2002. Causes of bleeding included radiation colitis (12 patients), gastric antral vascular ectasia ­ watermelon stomach (6 patients), esophagus,stomach and colon angiodysplasia (2 patients), radiation gastritis (1 patient) and Osler-Weber-Rendu Syndrome (1 patient). Results: A total of 49 sessions were performed (mean 2.2 sessions / patient). Succesful endoscopic APC treatment was achieved in 18 patients (85,8%). Complications were observed in 2 patients that referred local pain after therapy and 1 patient that developed a rectal stenosis succesfully reversed in one session of endoscopic dilation. No mortality related to APC was observed. Conclusions: APC is a safe, effective, and relative low-cost hemostatic modality for bleeding vascular lesions of the gastrointestinal tract. Therefore, APC should be considered as a first-line therapy for these conditions (AU)

A case of gastric antral vascular ectasia treated with argon plasma coagulation / 대한내과학회지

Gastric antral vascular ectasia (GAVE) is a rare but important cause of chronic gastrointestinal bleeding. Endoscopically, it has characteristic thickened red vascular folds radiating from the pylorus to the antrum. Diagnosis is made primarily by endoscopy. Histologic examination of the endoscopic mucosal biopsies may confirm the endoscopic diagnosis. Many treatment modalities of the gastric antral vascular ectasia exist. One of them, the argon plasma coagulation (APC) is an excellent therapeutic tool. Inactive argon gas is converted to ionized form by means of electrical energy. Ionized argon plasma conducts high frequency electrical energy to tissues and leads coagulation necrosis of tissues. We experienced a case of gastric antral vascular ectasia presenting melena for about one month in a 72-year-old man treated endoscopically in four sessions with argon plasma coagulation.

A Case of Watermelon Stomach Treated by Hemigastrectomy / 대한소화기내시경학회지

Gastric antral vascular ectasia (watermelon stomach) is a rare cause of chronic gastrointestinal bleeding, characterized endoscopically by a distinctive appearance of prominent red vascular folds traversing the gastric antrum and radiating to the pyloric sphincter; this appearance has been likened to the dark stripes on the surface of a watermelon. The etiology is unknown, and the usual presentations are iron-deficiency anemia and melena due to chronic gastric blood loss. Diagnosis is made by the characteristic endoscopic appearance and histologic findings. The treatment of choice is not known yet; surgical resection is curative method, but results from endoscopic treatment with heat probes or lasers are promising. We experienced a case of gastric antral vascular ectasia presenting with epigastric pain and melena in a 34-year-old female. The patient was treated with hemigastrectomy and Billroth II anastomosis.

A Case of Watermelon Stomach ( Gastric Antral Vascular Ectasia ) / 대한소화기내시경학회지

Watermelon stomach or gastric antral vascular ectasia is a rare disorder causing gastric blood loss and iron deficicncy anemia. Endoscopically, it has characteristic thickened red vascular folds radiating from the pylorus to the antrum. This condition is often mis- diagnosed as antral hemorrhagic gastritis. Diagnosis is made primarily by endoscopy. Histologic examination of the endoscopic mucosal biopsies may confirm the endoscopic diagnosis. Treatment for watermelon stomach includes steroids, estrogen-progesterone combinations, somatostatin antagonists, tranexamic acid, heater probe, and laser therapy. Herein we report a case of watermelon stomach presenting with general weakness and persistent iron deficiency anemia for about 2 years in a 70-year-old woman.
