“…The present study reconfirms the observations of several investigators showing that distension interferes with intestinal hemodynamics [1,3,6,7,[13][14][15][16]. While most of the authors reported hemodynamic impairments only for intraluminal pressures higher than 25-30 mm Hg, the present re sults show that an increase in vascular resistance is still observed for in traluminal pressures of near 10 mm Hg.…”

“…In the case of the intestine, this factor of a mechanical nature, is dependent either on the pressure in the gut lumen (distension) or on the activity of the muscular coats of this organ (motility). Numerous authors showed either by in vivo or in vitro studies that distension of the gut lu men affects mesenteric hemodynamics by increasing the vascular resist ance to blood flow [1,3,5,7,[13][14][15][16]. As far as the hemodynamic effects of spontaneous changes in motor activity of the small bowel are con cerned the data available so far remain conflicting.…”

“…However, it contributes to the exploration can be painful for the patient, both during implementation and in the hours after, by causing bloating that lasts until most of the air has been removed. Other side effects of prolonged air insufflation, although rare, may be the explosion of the colon when making a therapeutic electrocautery (2), perforation (3), air embolism (4) or ischemia of fragment swelling from the obstruction of blood flow due to pressure on the vessels of the colonic wall (5). The CO 2 , due to a much greater water solubility than that of the gases that form the ambient air, presents a more rapid removal, after passing from the colon into the bloodstream, which is associated with less strain and abdominal pain during and after the colonoscopy (6-9) and less disturbance of parietal blood flow by its potencial vasodilative effect (10).…”

“…Acute ischemia may be divided into occlusive or non-occlusive causes [13]. Occlusive etiologies include intravascular mechanical obstruction (thrombotic or embolic) in the setting of acute mesenteric ischemia or classically as a complication of aortic surgical procedures.…”
