The movement of the stomach after gastrectomy was studied by cine-fluoroscopic and photo-optical technique in patients undergoing pylorus preserving gastrectomy (pyloric canal being preserved approximately 1.5 cm in 8 cases; group A) or antrum Preserving gastrectomy (pyloric antrum being preserved 3-5 cm in 16 cases; group B).<BR>All patients were operated on in our clinic for a benign lesion located near the angle of the stomach.<BR>Results:<BR>1) In the early postoperative period, the oral gastric remnants showed remarkable dilatation in group A. The dilatation was also observed in group B, but less prominent.<BR>2) For the recovery from the gastric dilatation and reappearance of gastric motility, it took much more time in group A than in group B.<BR>3) Co-ordinated movements across the anastomotic site were recognzied about one month after operation in group B and about two months in group A.<BR>4) Antiperistalsis at the preserved antrum during an early postoperative period was observed in 2 of 16 cases in group B. The antiperistalsis in the two cases turned into normo-peristalsis in about two months.<BR>5) From the results obtained, the preserved antrum showed an excellent func-tional drainage effect and plays an important role for the transportation of the gastric content.<BR>6) In conclusion, antrum preserving gastrectomy results in a good postoperative gastric motility and is an excellent operative method for the benign lesions located near the angle of the stomach.
