GAVE (Gastric Antral Vascular Ectasia), also known as “Watermelon Stomach”, is a condition in which the blood vessels in the lining of the stomach become fragile and become prone to rupture and bleeding. The stomach lining exhibits the characteristic stripes of a watermelon when viewed by endoscopy.
Is GAVE treatable?
Endoscopic therapy, particularly treatment with Argon Plasma Coagulation, has shown to be as effective and also safer than surgery, and should be considered the first-line treatment for patients with GAVE-related bleeding.
How common is gastric antral vascular ectasia?
Gastric antral vascular ectasia (GAVE) syndrome, also known as watermelon stomach, is a rare but significant cause of severe acute or chronic gastrointestinal blood loss in the elderly.
What is APC treatment for GAVE?
APC is a modality of non-contact electrocoagulation that applies high-frequency energy into tissue to cause thermal effects, which can be used for hemostasis. APC has been used successfully to treat GAVE with an effective transient response, but primary failure rates of therapy of up to 14% have been reported.

Is APC treatment painful?
Of the 152 patients, 26 (17%) reported pain sensation during or after APC. The median pain sensation reported by the patients on the standardized scale was 3.7.
Is APC a surgery?
This new technique offers a wide variety of advantages. The limited penetration depth makes APC surgery a safe procedure; damage to neighbouring tissue can be avoided. The APC technique is a useful and comparable inexpensive method to achieve devitalisation of tissues and easy to handle hemostasis.
What is APC treatment for AVM?
Argon plasma coagulation (APC) is an electrocoagulation technique commonly used for treatment of gastrointestinal bleeding secondary to arteriovenous malformations (AVMs). Although this modality is generally safe, a rare complication reported is perforation.
How long is APC procedure?
APC typically takes less than fifteen minutes and you go home on the same day. APC is a minimally invasive endoscopic procedure, so it doesn’t require any incisions (cuts) on the outside of your body.
Why is APC done?
Interpretation: APC is a safe and effective modality for treatment of early gastric cancer with intramucosal invasion untreatable by surgical resection or EMR. However, further observations are necessary to determine the long term prognosis of patients undergoing this treatment.
How effective is APC?
APC session intervals range from every 4 to every 8 weeks. A mean of 1.7 to 3.7 treatment sessions is necessary for control of bleeding. APC improves rectal bleeding in 80% to 90% of cases, as well as symptoms of tenesmus, diarrhea, and urgency in 60% to 75% of cases.
What are the side effects of argon plasma coagulation?
The major complications reported are mucus discharge, rectal pain, and rectal ulcerations, which are most likely self-limiting and rarely require intervention[24]. Severe complications, including fistulation and stricture formation, were reported to affect approximately 3% of patients in several studies[22].
What is a colonoscopy with APC?
Argon plasma coagulation (APC), sometimes referred to as argon photocoagulation, is a medical procedure that uses argon gas during a colonoscopy or an upper endoscopy to control bleeding from certain lesions in the gastrointestinal tract.
Can APC cause ulcers?
Superficial ulceration occurs following APC, which typically heals within 2-3 wk. Despite theoretical safety advantages due to reduced depth of penetration, all of the complications that have been reported with other thermal hemostasis techniques may occur.
What cancers are associated with the APC gene?
Adenomatous polyposis coli (APC) is a gene that suppresses tumor growth. If the APC gene is defective, it makes the gene unstable and more susceptible to additional changes that may lead to colon and rectal cancers.
What does APC positive mean?
Your testing shows that you have a pathogenic mutation (a disease-causing change in the gene, like a spelling mistake) or a variant that is likely pathogenic in the APC gene. Both of these results should be considered positive.
How common is APC mutation?
APC is altered in 5.26% of desmoplastic/nodular medulloblastoma patients [3].
Is APC a tumor marker?
The APC protein acts as a tumor suppressor, which means that it keeps cells from growing and dividing too fast or in an uncontrolled way. It helps control how often a cell divides, how it attaches to other cells within a tissue, and whether a cell moves within or away from a tissue.
What is the rarest genetic mutation?
Summary. KAT6A syndrome is an extremely rare genetic neurodevelopmental disorder in which there is a variation (mutation) in the KAT6A gene. Variations in the KAT6A gene can potentially cause a wide variety of signs and symptoms; how the disorder affects one child can be very different from how it affects another.
Can an APC diagnose?
Diagnosis/testing.
The diagnosis of an APC-associated polyposis condition is established by identification of a heterozygous germline pathogenic variant in APC.
Is APC gene inherited?
Overview. Familial adenomatous polyposis (FAP) is a rare, inherited condition caused by a defect in the adenomatous polyposis coli (APC) gene. Most people inherit the gene from a parent. But for 25 to 30 percent of people, the genetic mutation occurs spontaneously.
