title: [Difficulties in diagnosis and surgical treatment of the angiodysplasia of the gastrointestinal tract].
abstract: BACKGROUND
  Angiodysplasia (AD) of the gastrointestinal (GI) tract is a rare cause of surgical GI bleeding. It frequently poses difficult problems in diagnosis and treatment. The purpose of this study is to find answers to these problems for a better management of the AD patients.
  
  
  METHODS
  From 1982 to 2006 a total of 75 patients suffering of AD of the GI tract were operated in our center. They represent about 3.6% of total patients operated for GI bleeding in the same period. The age of the patients was between 9 and 81 years old, with two peaks: one between 21 and 40 years old and the other between 51 and 70 years old. The localisation of the lesions was: righ colon +/- ileum 31 patients (41.33%), stomach 13 patients (17.33%), jejunum 6 patients (8%), descendent colon +/- sigmoid 5 patients (6.66%), rectum 4 patients (5.33%), pan-colonic 4 patients (5.33%), sigmoid colon 2 patients (2.66%), cecum + transverse colon 2 patients (2.66%), ileum 2 patients (2.66%), sigmoid colon + jejunum 1 patient (1.33%), cecum + sigmoid colon 1 patient (1.33%), cecum +/- sigmoid colon + jejunum 1 patient (1.33%), jejunum + ileum 1 patient (1.33%), pan-colonic + rectum 1 patient (1.33%). According to Moore classifications 29 patients were type 1 (38%) and 45 patients were type 2 (60%). In one patient AD was associated with Crohn disease (type 4 Fowler).
  
  
  RESULTS
  The main symptom in AD was repetitive GI bleeding, of various amplitude, often obscure in origin, the patients having many hospital entries. The medical examination that give us the best help was selective angiography which was positive in 34 of 40 patients (85%). Upper and lower endoscopy were give to 50 surgical patients, being diagnostic in 32 (64%). Histopathologic examinations confirm the diagnosis of AD in all cases, without using injection techniques. All patients were operated for symptomatic AD. Other 11 patients non included in this study were find to have angiodysplastic lesions on operatory specimens for other diseases. The main indications for operative in AD were: continuing digestive hemorrhage of growing amplitude with detected source (54 patients = 72%), inefficient endoscopic and angiographic hemostasis (8 patients = 10.66%) and patients with massive bleeding without any preoperative evaluation (13 patients = 17%). Intraoperative exploration produced little information because of the mucosal and submucosal localisation of the lesions. Operative panendoscopy was the most rewarding investigation. Various types of resections were practiced depending on the site(s) known or presumed of the lesions. Perioperative morbidity was 23% (21 patients), rebleeding being in 4 patients (5.33%). Perioperative mortality was 12% (9 patients) a consequence of advanced age, comorbid conditions and frequent extreme emergency of the operations.
  
  
  CONCLUSIONS
  Although rare as a cause of surgical digestive bleeding, AD poses often difficult problems of diagnosis and treatment. In patients with GI bleeding, without evident cause, multiple investigated, especially elderly but not always, we must think of an AD.
