4.Gastric Emptying: Radiological Findings.-After acid-fundic selective vagotomy without gastric drainage radiographic examination 5 months after surgery (Table X ) showed complete emptying of the stomach within 4 hours in 92 per cent of the patients, within 6 hours in 5.3 per cent, and after 6 hours in 2'7 per cent. These results were far better than those after total selective vagotomy without gastric drainage.
CONCLUSIONSThe clinical and secretory results in the present series support the following conclusions :-I. Acid-fundic selective vagotomy achieves a complete denervation of the parietal cell mass and reduces basal and stimulated acid gastric secretion to the same extent as total selective (or truncal) vagotomy.2. Acid-fundic selective vagotomy, preserving the vagal branches of the antrum, does not affect gastric emptying and makes gastric drainage unnecessary.The clinical results, although after only a short follow-up, suggest that the procedure can be considered as the treatment of choice in most patients with an uncomplicated duodenal ulcer (76 per cent in our series). The gastric drainage procedure is required only in cases of stenosiog duodenal ulcer with delayed gastric emptying. Pyloropiasty is also mandatory in the treatment of bleeding ulcer and of perforated ulcer (if the suture is stenosing).Acknowledgements.-We are indebted to our anaesthetists, Dr. R. Aloi and Dr. A.
