Upper gastrointestinal bleeding from duodenal vascular ectasia in a patient with cirrhosis.
(9/22)
We report a cirrhotic patient with duodenal vascular ectasia and spontaneous bleeding. The bleeding was successfully controlled with argon plasma coagulation. Duodenal vascular ectasia may be a cause of upper gastrointestinal bleeding in patients with cirrhosis, and argon plasma coagulation may be effective and safe to achieve hemostasis of this lesion.

Gastrointestinal angiodysplasia in chronic renal failure.
(10/22)
Gastrointestinal (GI) hemorrhage is a frequent and sometimes life-threatening complication of end-stage renal failure. Angiodysplasia (AD), vascular malformation, is the most common cause of recurrent lower-intestinal hemorrhage in patients with renal failure. We report four chronic hemodialysis patients with AD. All patients presented with severe anemia requiring transfusion. GI hemorrhage ceased spontaneously in three cases and after treatment with argon plasma coagulation in another. Diagnosis of AD is usually challenging, since its cause is still unknown, and its clinical presentation is variable. Lesions are multiple in 40-75% of cases, often located in the stomach and duodenum but can affect the colon and the jejunum. Diagnosis is improved by endoscopy which has a much higher sensitivity compared to angiography. Capsular endoscopy may reveal the hemorrhage site in the small intestine when regular endoscopy fails, and therapeutic intervention usually include argon plasma coagulation. (+info)
Heterotopic mesenteric ossification after gastrectomy for watermelon stomach.
(11/22)
Heterotopic mesenteric ossification is a rare disorder. Only a few cases have been reported in the literature, associated with previous abdominal surgery or trauma. We report a case of heterotopic mesenteric ossification leading to abdominal sepsis, after abdominal operation for recurrent gastric bleeding, due to gastric antral vascular ectasia (GAVE), otherwise called "watermelon stomach", another rare disorder.

Argon photocoagulation in the treatment of gastric antral vascular ectasia and radiation proctitis.
(12/22)
Gastric antral vascular ectasia (GAVE) and radiation proctitis are two vascular disorders of the gastrointestinal tract that typically present with recurrent gastrointestinal bleeding. Although the pathogenesis of either condition is not known, they are unlikely to be similar. GAVE appears to be related to autoimmune disorders or cirrhosis, while radiation proctitis is the result of pelvic irradiation, most commonly used for the treatment of pelvic malignancies. Medical therapies for both conditions are not typically effective, and surgical therapies are usually not required because endoscopic treatment, aimed at coagulation of the underlying vascular lesions, has evolved as the most effective therapy. There is limited evidence in the literature for the use of medical and surgical therapies, with most of the evidence coming from case reports involving small numbers of patients. In the present article, we review the evidence for the use of argon plasma photocoagulation (APC, the most commonly used endoscopic modality) in the treatment of GAVE and radiation proctitis. (+info)
Computed virtual chromoendoscopy - enhanced videocapsule endoscopy is of potential benefit in gastric antral vascular ectasia syndrome refractory to endoscopic treatment.
(15/22)
Gastric antral vascular ectasia (GAVE) syndrome represents a rare cause of gastrointestinal bleeding. More extensive small-bowel involvement must be excluded in those patients with GAVE syndrome in whom aggressive endoscopic treatment of antral lesions results in lack of control of digestive bleeding, and for this subset of patients videocapsule endoscopy examination should be considered. However, since the dim angioectatic lesions, even if located in the gastric antrum, might be difficult to accurately outline with standard endoscopy, virtual chromoendoscopy techniques have been employed to aid in their detection, and the presented case illustrates how Fujinon intelligent color-enhancement (FICE) technology implemented in videocapsule endoscopy clearly emphasizes the vascular morphology and delineation of antral angioectasias, allowing better targeted endoscopic treatment and improving patient outcome.
