MANRIQUE, María Nelly; FRISANCHO, Oscar; RIVAS WONG, Luz  y  PALOMINO, Américo. Jejunal GIST with obscure gastrointestinal bleeding. Rev. gastroenterol. Perú [online]. 2011, vol.31, n.3, pp.289-296. ISSN 1022-5129.

We report the case of a woman of 84 years with a history of cardiac arrhythmia and hemorrhoids. She had multiple hospitalizations and transfusions for symptomatic iron deficiency anemia, endoscopic studies showed only small diverticula and colon polyps. He was later hospitalized with bloody stools red wines, upper endoscopy and colonoscopy showed gastritis, small colonic ulcers, colonic polyp and multiple diverticula. Readmitted with bleeding of obscure origin, on that occasion showed gastritis, antral erosions, small ulcers, colon polyps and colon ulcers in the process of healing, capsule endoscopy showed angiodysplasia in jejunum, anterograde enteroscopy detected some erythematous lesions in proximal jejunum without evidence of bleeding. Again hospitalized for melena and abdominal pain, upper endoscopy revealed gastric and duodenal angiodysplasia were treated. The last entry indicated a time of two years disease, the current episode with wine-red colored stools, Hb: 8.4 g, for which he received two units of PG. Endoscopy showed gastric angiodysplasia, which was treated with thermocoagulation (argon plasma). In the entrance examination showed no signs of hypovolaemic decompensation. Approached as a problem of obscure gastrointestinal bleeding were repeated several endoscopic examinations without results. She re-bled being hospitalized, capsule endoscopy was performed showing acute bleeding in the jejunum, complemented by new anterograde enteroscopy that showed ulcerated lesions of the jejunum, the area was marked with indian ink. Exploratory laparotomy was indicated. In the surgical intervention it was in edge antimesentérico of yeyuno, a round tumor (6x6 cm) of extraluminal growth, which compromised the wall without sticking to other structure, Resection of the tumor and jejuno-jejunal anastomosis was realized. The histological study with immunohistochemistry showed an Intestinal Stromal Tumor (GIST), intermediate risk, histological pattern fusiform, with scarce mitosis; the lesion was dependent on the muscularis propria of the small intestine. In conclusion, this case involves a woman with a jejunal GIST whose clinical presentation was hemorrhage of unknown origin which was a diagnostic problem and thanks to the advent of new endoscopic procedures (enteroscopy and capsule endoscopy) could locate the place of injury and subsequent surgery.
