In more than 1,000 radiological and endoscopic examinations of the smooth muscle hollow organs of the upper intestinal tract, crysalline glucagon (0.2 to 0.5 mg., average dose 1 u/kg. body weight given at a single intravenous injection) resulted in a significant relaxation and reduction of peristalsis. This effect was less marked in the colon and recto-sigmoid. In five patients with colonic diverticulosis it had no effect. In 150 patients it was found that the onset of hypotonia after injection of glucagon increases from proximal to distal, the duration of maximal reduction in peristalsis decreasing distally. Glucagon is indicated for reducing the tone of smooth muscle hollow organs in order to judge their elasticity and to distinguish between functional and organic causes of a stenosis or increased size of folds. The rapid onset of peristaltic inhibition makes various diagnostic and therapeutic endoscopic procedures simpler or even possible. Compared with the usual atropin-like antispasmodics, glucagon has the advantage of being free from side effects apart from transient hyperglycaemia. Diabetes mellitus requiring insulin is a (relative) contra-indication to the use of glucagon.

A method for tubeless, double-contrast examination of the small bowel is described. Oral contrast medium and capsules which effervesce in the small bowel resulted in double-contrast demonstration of the small bowel in 90 out of 130 patients. Transit through the small bowel was reduced to an average of 78 minutes, due to increased peristalsis resulting from distension by the intralumental gas. For comparison, average transit time in a control group of 83 patients was found to be 126 minutes. The differential diagnosis of stenosing processes and additional information concerning space-occupying lesions was furthered by small bowel hypotonia induced by the intravenous injection of 15 to 45 mg. propantheline bromide (Probanthine) or 1 to 2 mg. glucagon. The method has the following advantages: 1. Improved demonstration of detailed mucosal pattern, 2. Reduced examination time and 3. Simultaneous visualisation of the entire small bowel.

The results of the double examination of the stomach in a series of 102 patients were compared with the findings at endoscopy. Nasogastric intubation was used to introduce the air into the stomach. Hypotonia was achieved mainly with glucagon. The radiologic error rate was 10 per cent, consisting of 7 per cent false negative and 3 per cent false positive findings. The diagnostic advantages of the double contrast technique over those of the conventional barium examination are discussed.

Immediate and satisfactory gastrointestinal hypotonia was induced in 48 patients with 5--10 mg of intravenous Pro-Banthine during radiographic examination; side-effects were minimal. If given intravenously in small doses, Pro-Banthine is a satisfactory alternative when glucagon is contraindicated or not available.

Hypotonic cholangiography was performed with intravenous glucagon in 12 patients who demonstrated complete nonspecific obstruction of the distal common bile duct during postoperative T-tube or transhepatic cholanglography. In 8 cases (67%), a diagnostic result was obtained. Abolition of smooth-muscle spasm at the choledochal sphincter by glucagon-induced hypotonia appears to be a useful adjunct to roentgenography of the bile ducts.

Different operations were performed on 15 patients with the Glucagon decreased tonus of the stomach and intestine. The drug was injected in doses 0.2, 0.3 and 0.5 mg. The resulting hypotonia of the stomach and duodenum facilitated performing the operations. No complications were noted.

Whereas intolerance reactions against contrast media are a well-known hazard during radiologic procedures, intolerance reactions to other preparations used in radiology are rare. Glucagon, frequently used to induce gastrointestinal hypotonia, is said to have almost no side-effects. A case of anaphylactic reaction during double-contrast upper gastrointestinal examination is reported. Pseudoallergic reaction to propylparaben, a preservative agent in glucagon, is suspected. IgE-antibodies to glucagon could not be detected by RAST.

On the basis of the experience with examination of 35 patients glucagon is recommended by the authors for radiopaque examinations of the gastrointestinal tract and bile ducts under conditions of hypotonia. It increases the diagnostic modality of the roentgenological examination.

Heterotopic gastric mucosa in the duodenal bulb is sometimes seen as elevated lesions. Radiological and endoscopic findings in 22 patients are reported, and the characteristic appearance on each study is described. Glucagon-induced hypotonia of the duodenal bulb facilitates the diagnosis.

We report the case of 52-year-old woman, who ingested 3.6 g of diltiazem, 16 g of potassium chloride and 6.5 g of magnesium, in a suicide attempt 4 hours before admission. She developed cardiorespiratory failure, with severe hypotonia and acute renal failure, in ECG third degree atrioventricular block was stated. The highest potassium concentration was 8.0 mmol/l, magnesium 2.15 mmol/l. As a result of multiple pharmacologic intervention, including intravenous fluids, calcium, glucagon, dopamine, dobutamine, norepinephrine, transvenous pacing and peritoneal dialysis (haemodynamic instability makes haemodialysis noneffective) the haemodynamic stabilization of cardiovascular system and normalization of potassium and magnesium concentration were achieved. The diltiazem concentration was measured using liquid chromatography, the result was 0.89 microgram/ml. She was discharged in a good clinical condition on day 26th.
