Arch Surg. 1964;89(1):208-214. doi:10.1001/archsurg.1964.01320010210023

Gastric freezing for control of the duodenal ulcer diathesis has been evaluated for 15 months at the Hennepin County General Hospital.* Our continuing clinical study aims to determine the possible prolonged effectiveness of this therapy. This report deals with 173 patients who have undergone a single gastric freeze, and 49 of the same patients who have been treated a second time. The duration of symptoms in these subjects has been from two months (one patient) to 47 years, and the average time has been ten years. All patients were referred by private physicians and had a documented duodenal ulcer prior to admission to our hospital.

Procedure  The gastric freezing procedure used in this series is the standard 50-minute gastric freeze using the Swenko hypothermia machine and the pioneer D-2 rubber balloon, with an average inflow temperature of −18 C (−0.4 F) and an average return temperature of −11 C (12.2
