Hypotonic Duodenography

Double contrast examination of the small bowel

“…A thick tube of the type recommended by Bilbao [5] is stiff and easier to manoeuvre in the stomach than a smaller and softer one. The contrast medium flows more rapidly through a tube with wide bore and large side holes.…”

“…Different techniques can be employed for duodenal intubation. We have followed the same principles as Bilbao [5]. Thus the tube is passed t'ia one nostril, which is easier to manoeuvre than via the mouth.…”

“…Colon enema was not given because it may cause reflux of fecal material to the ileum. The intubation was performed according to Bilbao [5], with the modification that we used a disposable polyethylene tube, 125 cm in length with a radiopaque tip and an outer diameter of 4.66 mm. A 145-cm Teflon-coated guide wire of stainless steel was used in order to place the tip of the tube at the level of Treitz's ligament or as far distal as possible in the duodenum.…”

Diagnostic difficulties with duodenal malignancies revisited: A new strategy

“…Selective hypotonic duodenography was first described in 1967 by Bilbao et al [17], and later by Eaton et al [18]. A modification of this original method is proposed using a Maglinte balloon enteroclysis catheter (Cook Europe, Denmark).…”

Complications of Gastrointestinal Intubation

“…The principal application of this technique is in intestinal decompression in patients with obstructive symptoms or paralytic ileus (3,4). Flexible tubes are also placed into the gastrointestinal tract for various other diagnostic or therapeutic purposes, including alimentation with liquefied food (5)(6)(7), hypotonic duodenography, enteroclysis, gastrointestinal secretory tests, and mucosal biopsy (8)(9)(10)(11)(12)(13).…”
