Potential of colonoscopy as a treatment for intussusception in children.

Background And Study Aims:  Invagination, which can occur in any part of the intestine, usually affects children and is the second most common cause of intestinal obstruction after pyloric stenosis. The cause of these intussusceptions in children is usually unknown and they typically occur within the ileocolic region. Management of pediatric patients with the condition often consists of surgical intervention.

Primary aortoesophageal fistula: a rare cause of acute upper gastrointestinal bleeding.

Acute upper gastrointestinal bleeding is a potentially life-threatening emergency, especially in the elderly. This condition accounts for approximately 1% of all emergency room admissions. Among the causes of such bleeding is aortoesophageal fistula, a dreaded but apparently rare condition, first recognized in 1818.

[Endoscopic treatment of colon vascular ectasia during bleeding with injection of adrenaline solution at 1:10,000 and monopolar electrocoagulation: an alternative approach. Case report].

Gastrointestinal bleeding accounts for 2% of all adult hospital admissions each year. Vascular ectasia is one of the most frequently reported cause of lower gastrointestinal bleeding. In almost 80% of patients with bleeding vascular ectasia will stop spontaneously, but will often recur.

Endoscopic papillotomy under ultra-sonographic control.

A new endoscopic method for performing endoscopic sphincterotomy is described. Only after correct positioning of the papillotomy device has been ascertained can papillotomy be carried out. We have used ultra-sonographic examination to confirm the correct placement of the papillotomy device.
