Prevalence of mid-gastrointestinal bleeding in patients with acute overt gastrointestinal bleeding: multi-center experience with 1,044 consecutive patients
ABSTRACT Video capsule endoscopy (VCE) and double-balloon enteroscopy (DBE) enable the detection of small intestinal lesions.
To examine causes of acute overt gastrointestinal (GI) bleeding and the prevalence of mid-GI bleeding, defined as small intestinal bleeding from the ampulla of Vater to the terminal ileum, in a multi-center experience in Japan in the VCE/DBE era.
Data were collected retrospectively from consecutive patients with acute overt GI bleeding in ten participating hospitals. All patients were examined by esophagogastroduodenoscopy and/or colonoscopy. When the source of bleeding was not identified after these procedures, patients suspected to have mid-GI bleeding were referred to our hospital and VCE/DBE was performed to determine the source of bleeding.
Of the 1044 patients with acute overt GI bleeding, 524 (50.2%) patients were diagnosed with upper GI bleeding, 442 (42.3%) with lower GI bleeding, and 13 (1.2%) with mid-GI bleeding. Gastric ulcer was the most common cause of bleeding (20.4%). Among cases of mid-GI bleeding, ulcers were found in 4 (30.8%) patients, erosions in 3 (23.1%), angiodysplasia in 3 (23.1%), submucosal tumor in 2 (15.4%), and hemangioma in one (7.7%). Seven lesions were located in the jejunum, 5 in the ileum, and one in both the jejunum and ileum. Analysis of age-related cause showed that the prevalence of mid-GI bleeding among younger patients under 40 years of age was higher (5%) than in other age groups (1-2%).
mid-GI bleeding is rare among Japanese patients with acute overt GI bleeding.

ABSTRACT: Lower gastrointestinal bleeding (LGIB) is defined as measurable bleeding from a source distal to the ligament of Treitz. LGIB is a broad term used to encompass the spectrum of symptoms ranging from minimal bleeding noticed on bathroom tissues associated with hemorrhoids to massive bleeding encountered with diverticular hemorrhage. Etiologies range from the rare small-bowel tumors to the frequently identified diverticular sources. To complicate matters further, the bleeding may be intermittent, leading to a challenging diagnostic and management dilemma.Der Internist 07/1991; 32(6):W49-55.

ABSTRACT: Bleeding lesions in the small bowel are a much more significant challenge in terms of detection and treatment than those of the stomach or the large bowel, and require extensive gastrointestinal evaluation before a diagnosis can be made. The authors report the case of an 81-year-old female patient who underwent small bowel segmental resection by single incisional laparoscopic approach for distal jejunalhemangioma, which caused severe anemia. An abdominal computed tomography scan demonstrated a highly enhancing polypoid tumor in the distal ileum. During the single incisional laparoscopic exploration using a 2 cm sized skin incision, jejuno-jejunal intussusceptions and a jejunal tumor were noted. Single incisional laparoscopy was performed to assist the jejunal segmental resection. Pathologic reports confirmed the lesion to be a jejunalhemangioma. The authors report an unusual case of jejunalhemangioma caused by intussusception and gastrointestinal hemorrhage, which was treated by single incisional laparoscopic surgery.05/2011; 80(5):362-6.

ABSTRACT: Objective Gastrointestinal stromal tumors (GISTs) are the most frequently occurring mesenchymal tumors of the GI tract. Double-balloon enteroscopy (DBE) and capsule endoscopy (CE) promise the detection and accurate diagnosis of small bowel diseases in patients with obscure GI bleeding (OGIB). The aim of the present study was to analyze the clinical characteristics of small bowel GISTs and the usefulness of DBE, CE and computed tomography (CT). Methods Among 705 cases with OGIB examined between December 2003 and January 2011, 12 (1.7%) cases of small bowel GIST were identified. We analyzed endoscopic appearance, tumor-size and location, detection rate by DBE, CE and CT and clinical course in each of these cases. Results Of the 12 patients with GIST, eight were men. The mean patient age was 53.6 years. The presenting symptoms in most patients included tarry stools and/or anemia. Six patients required blood transfusions. The detection rates of DBE, CE and CT were 92%, 60% and 67%, respectively. All cases, except for one incomplete study, were identified using DBE; however, one case was not diagnosed as a tumor because of the presence of extramural growth. A pathological diagnosis of GIST was obtained using biopsies during DBE in three (45%) of seven cases. Lower detection rates were found in cases with intramural and extramural growth, larger tumors (≥35 mm) detected by CE and intraluminal growth and smaller tumors (<35 mm) detected by CT. Conclusion DBE or a combination of CE and CT are thus considered to be useful for detecting small bowel GISTs.Internal Medicine 01/2012; 51(19):2675-82.
