Rebleeding was more frequent in patients who did not receive further interventions Lancet ; In fact, other authors have manage this limitation the same way as us, in fields in which size is much more relevant, as polyps size estimation Although a significant number of patients with no bleeding episodes have small bowel lesions, no studies have correlated the size and number of intestinal angiodysplasia with the angiodixplasia of a given patient.

Thalidomide is a drug with a potent anti angiogenic effect which inhibits VEGF and reduces its level significantly 1.

Failing this, angiography and emolization with particles is another microinvasive treatment option, which avoids the need for surgery and bowel resection. None of the patients required transfusions during the study period. Then, in selected cases, with small isolated lesions, clinical follow-up with or without additional medial therapies might be the best choice.

We carried out a prospective study of a series of multitransfused patients with gastrointestinal bleeding and severe ferropenic anaemia who did not respond to endoscopic argon plasma coagulation treatment or somatostatin analogue therapy. Histologically, it resembles telangiectasia and development is related to age and strain on the bowel wall. Any controversial finding was extensively discussed. Discussion Thalidomide shows anti-inflammatory, immunomodulatory and anti-angiogenic properties and inhibits VEGF production, which is considered a key factor for the formation of the vascular endothelium in the initial stages of angiogenesis.

Increased expression of angiogenic factors, like basic fibroblast growth factor bFGF and vascular endothelial growth factor VEGFis also believed to play a role in the pathogenesis of colonic angiodysplasia.

Eficacia de la talidomida en la hemorragia digestiva por angiodisplasias. Mortality was significantly higher in patients with large angiodysplasia 25 vs. Capsule endoscopy versus standard test in influencing management of obscure digestive bleeding: Intewtinal analogues for bleeding gastrointestinal angiodysplasias: So far, few reports have been published of clinical cases showing the efficacy of thalidomide in intedtinal treatment of gastrointestinal bleeding due to angiodysplasias 1,2 or severe proctitis following radiotherapy 3.

Long-acting octreotide is effective in controlling rebleeding angiodysplasia of the gastrointestinal tract. Information about blood tests, recurrent gastrointestinal bleeding, additional diagnostic or therapeutic procedures, red cells transfusions before CE, and subjective health perception were collected.

J Cardiovasc Transl Res. Some case reports have described the positive influence of octeotride or hormonal therapy 15but our patients did not receive any of those therapies.

SUMMARY Gastrointestinal angiodysplasia intestina, a very common cause of digestive hemorrhage among elderly patients with chronic renal insufficiency.

Angiodysplasia

These terms have varying pathophysiologies, with a common anigodisplasia of GI bleeding. Brant WE, Helms C. Our series show a lower rebleeding rate than previous works for those patients 9. Material and methods We carried out a prospective study of a series of multitransfused patients with gastrointestinal bleeding and severe ferropenic anaemia who did not respond to endoscopic argon plasma coagulation treatment or somatostatin analogue therapy.

Gastrointestinal bleeding and chronic ferropenic anaemia resulting angiodisplasai vascular lesions intestinwl the digestive tract sometimes pose a difficult therapeutic challenge due to the location and multiplicity of such lesions.

In contrast, ours has shown a much lower rebleeding rate, possibly related to the therapeutic procedures performed in cases with a greater clinical impact lower hemoglobin levels, higher transfusion requirements. Individuals with large angiodysplasia had higher transfusion requirements, a higher proportion of therapeutic procedure performed after CE, lower hemoglobin concentration, and a lower rebleeding rate.

We also studied angiodysplasia lesion numbers in each patient.

Aliment Pharmacol Ther ; Angiodysplasia in the upper GI tract occurs most often in the stomach and duodenum. In cases with negative endoscopic findings and high clinical suspicion, selective angiography of the mesenteric arteries is sometimes necessary, but this allows for interventions at time of the procedure.

Diseases of the digestive system primarily K20—K93— These findings support that patients with large angiodysplasia would benefit from further therapeutic interventions. In severe cases or cases not responsive to either endoscopic or medical treatment, surgery may be necessary to arrest the bleeding.

Sharma R, Gorbien Inhestinal The decision between push enteroscopy and double balloon enteroscopy was made depending on the location of the lesions, reserving push enteroscopy for those placed in the distal duodenum, and double balloon enteroscopy for the rest, with an upper, lower or both accesses.

Introduction Wireless capsule endoscopy WCE has shown a good diagnostic yield for obscure gastrointestinal bleeding, better than push enteroscopy 1barium follow through 2 and computed tomography 3.
