Selective endoscopic contrastography (S.E.C.): an original association of radiology and endoscopy of the small and large intestine.

A more complete diagnostic information can be obtained by "carrying" the contrast medium through the fibercoloscope to those sites of the bowel where neither radiology alone nor endoscopy alone succeed in solving the diagnostic problem. The indications for a selective perendoscopic contrast study during coloscopy are few, but well defined and certainly not negligible:--demonstration and assessment of stenoses (unclarified by radiology and endoscopy);--accurate evaluation of the last ileal loop;--diagnostic study of ileo-colic surgical anastomoses;--fistulous tracts. Seventy-six patients were examined, without complications. The method proved useful in 42% of cases, conclusive in 33%, useless or inconclusive in 17%, unsuccessful in 8% (technical difficulties). On this basis, selective endoscopic contrastography is considered of use whenever its specific indications apply.

Fasting and after meals serum gastrin levels were determined in healthy subjects and patients with different gastroenterological diseases (duodenal and gastric ulcer, hiatal hernia with gastroesophageal reflux, Billroth II gastric resection, atrophic gastritis, Zollinger-Ellison, Ménétrier, chronic calcifying pancreatitis, gastric carcinoma and lymphoma). The results pointed to the usefulness of evaluating both fasting levels and "gastrin curve" after meals as an expression of the rapidity of response of hormone-secreting gastric cells. Calculation of the I.G.O. (Integrated Gastrin Output) must also be carried out to provide a parameter from which the overall ability of G cells to secrete in response to feeding can be assessed.
