DOCUMENT INFO
Description: In the chronic form, symptoms are recurrent and intermittent episodes of upper abdominal discomfort, which is sometimes accelerated by meals, and nausea and vomiting, but they are mild and transient. Mechanical factors include adhesions, a long mesentery, a long afferent loop, dilated atonic stomach, retrograde peristalsis, vomiting, pregnancy, labor, and other causes of increased abdominal pressure. Probably, the most commonly accepted explanation of intussusception is peristalsis, retro- or antegrade, which, after initial invagination, continues to push the intussuscepting jejunum through the gastric stoma.3 After a Billroth II anastomosis, there is an alteration of the jejunal motor pattern with a high incidence of nonpropagating contractions distinct from propulsive motor pattern occurring in the intact jejunum.
