CONSIDERABLE controversy has arisen over the physiologic and morphologic effects of gastric "freezing."1 The basic issue has not been settled whether or not actual freezing of the stomach wall occurs or is desirable. The purpose of the present study was to measure gastric wall temperatures during gastric "freezing" and to determine the relationship, if any, to morphologic changes.

Materials and Methods 

Equipment.  —Throughout the experiments an OEM model x-90 * gastric hypothermia machine with a flow rate of 1,500 ml per minute over the range of temperatures was used employing 95% ethyl alcohol as the coolant. A latex rubber balloon with a stomach-like configuration and a pleat along the area corresponding to the greater curvature aspect of the fundus was utilized.† A multifenestrated "nozzle" was affixed to the distal tip of the inflow tubing to produce a spray effect upon the fluid entering the balloon under pressure.

Procedure.  —Twenty-five fasting
