The diagnosis is mainly based on endoscopic pattern and, for uncertain cases, on histology. GAVE is characterized by a pathognomonic endoscopic pattern, mainly represented by red spots either organized in stripes radially departing from pylorus, defined as watermelon stomach, or arranged in a diffused-way, the so called honeycomb stomach. The histological pattern, although not pathognomonic, is characterized by four alterations:vascular ectasia of mucosal capillaries, focal thrombosis, spindle cell proliferation and fibrohyalinosis, which consist of homogeneous substance around the ectatic capillaries of the lamina propria. The main differential diagnosis is with Portal Hypertensive Gastropathy, that can frequently co-exists, since about 30% of patients with GAVE co-present a liver cirrhosis. Autoimmune disorders, mainly represented by Reynaud's phenomenon and sclerodactyly, are co-present in about 60% of patients with GAVE; other autoimmune and connective tissue disorders are occasionally reported such as Sjogren's syndrome, systemic lupus erythematosus, primary biliary cirrhosis and systemic sclerosis. In the remaining cases, GAVE syndrome has been described in patients with chronic renal failure, bone marrow transplantation and cardiac diseases. The pathogenesis of GAVE is still obscure and many hypotheses have been proposed such as mechanical stress, humoural and autoimmune factors and hemodynamic alterations. In the last two decades, many therapeutic options have been proposed including surgical, endoscopic and medical choices. Medical therapy has not clearly shown satisfactory results and surgery should only be considered for refractory severe cases, since this approach has significant mortality and morbidity risks, especially in the setting of portal hypertension and liver cirrhosis.

The treatment of GAVE relies on endoscopic approaches such as electrocoagulation(argon plasma coagulation, laser therapy, heater probe therapy, radiofrequency ablation), cryotherapy, and band ligation. In refractory cases, antrectomy may be considered. In the event of an associated cirrhosis and portal hypertension, it has been suggested that antrectomy could be an option, provided the mortality risk isn't considered too great. We report the case of a 67-year-old cirrhotic patient who presented with GAVE related GIB, unresponsive to multiple endoscopic treatments. The patient had a good liver function(model for end-stage disease 10). After a multidisciplinary meeting, a transjugular intrahepatic portosystemic shunt(TIPS) procedure was performed, in order to treat the cirrhosis associated ascites. The outcome was successful. An antrectomy was then performed, with no recurrence of GIB and no transfusion need during three months of follow up. In this case, the TIPS procedure achieved a complete ascites regression, allowing a safer surgical treatment of the GAVE-related GIB.展开更多

Her past history included autoimmune hepatitis. Esophagogastroduodenal endoscopy was performed to investigate the bleeding source and revealed multiple linear gastric vascular malformations in the antrum and cardia, compatible with Gastric antral vascular ectasia (GAVE). Endoscopic ablation was carried out with the tip of the hot biopsy forceps without opening at soft coagulation mode of 80W. The patient tolerated the procedure well and there were no complications associated with endoscopic therapies. After two sessions of endoscopic ablation her anemia improved to around 10 g/dL, an increase of 3.6 g/dL. Various endoscopic treatments have been described to manage GAVE. The most popular is argon plasma coagulation (APC), although APC is associated with over-distension induced by the argon plasma gas. To avoid over-distension and to reduce the abdominal discomfort/pain of this patient,we have used hot biopsy forceps instead of APC. Our case suggests that this procedure is effective, easy and convenient,as no special equipment or skill is necessary.展开更多

Blood tests revealed sudden drop of haemoglobin and an urgent gastroscopy revealed gastric antral vascular ectasia (GAVE) or “watermelon stomach”. GAVE is a rare but well recognised cause of acute bleeding in systemic scleroderma patients and should be kept as a differential diagnosis in the work up of anaemia in these patients.展开更多

Included patients had an endoscopic diagnosis of GAVE with associated upper gastrointestinal bleeding or iron deficiency anemia.RESULTS Seven out of 15 patients had classic watermelon description for GAVE, 1/15 with diffuse/honeycomb pattern and 6/15 with nodular GAVE per EGD description. Seven out of 15 patients required multimodal treatment. Four out of six of patients with endoscopically nodular GAVE required multimodal therapy. Overall, mean pre-and post-treatment hemoglobin(Hb) values were 8.2 ± 0.8 g/dL and 9.7 ± 1.6 g/dL, respectively(P ≤ 0.05). Mean number of packed red blood cells transfusions before and after treatment was 3.8 ± 4.3 and 1.2 ± 1.7(P ≤ 0.05), respectively.CONCLUSION Patients with nodular variant GAVE required multimodal approach more frequently than non-nodular variants. Patients responded well to multimodal therapy and saw decrease in transfusion rates and increase in Hb concentrations. Our findings suggest a multimodal approach may be beneficial in nodular variant GAVE.展开更多
