Louisiana State University Medical School investigators have joined p from other institutions in a searching three-year study to evaluate the effectiveness and safety of the procedure of treating peptic-ulcers by freezing the stomach lining. ^ The study includes both cal experience and tests with animals. Dr. -G. Gordon 1 .y, clliii- c^p^fesoF^'ln^iiie at LSU, and^Dr^Mohammed Aiik, associate profes^F^oTTsni^sy, met here recently with representatives from the medical schools of Vanderbilt, Chicago and Duke universities and the Scott™1' ' iinic of Temple, . » to consider preliminary reports -on tixe investigation which was started last. October, Dr. McHardy'First' Dr. McHardy was .the first physician to use the .freezing | technique in New Orleans. ■ - The method was developed about three years ago by a group of doctors at the University of Minnesota headed by Di\ Owen H. Wangensteen. A patient swallows a stomach-shaped plastic balloon and tube. After the balloon is inflated, alcoholis circulated through the tube at a temperature of minus 18 degrees-.Centigrade, which is near zero on the Fahrenheit scale. Hie chilling is continued for 50 minutes, until the stomach wall presumably is frozen solid. In. most patients the freezing halts the secretion of digestive acids by the stomach. It is these acids which destroy the stomach lining and cause the pain and sometimes result in the hemorrhage associated with ulcers. Many patients have been able to eat hearty meals two hours after freezing, and have had no recurrence of the ulcer symptoms, Most'Effective The technique has been most effective on duodenal ulcers. It is not recommended for gastric ulcers. Physicians do not understand the exact cause, of ulcers.. They know only that in ulcer patients, the stomach secretes more than the normal amount of adds. They suspect that some persons are born with a tendency to develop ■ulcers. ' "The -: atment of ulcers has been through diet and medication intended to inhibit, and- counteract the secretion of juices in the stomach. But in severe cases where there has been blockage, perforation or hemorrhage, surgery .has 'been a last resort. Portions of the stomach are removed, or the vagus nerve, which controls secretions, is divided j; Aim of Study The aim of the study in which the LSU doctors are participating is to determine whether the freezing method is in fact a revolutionary development which will provide relief and' possibly a cure without, creating any other hazard to the patient. . ■ At. the., meeting here, Drs. McHardy and Atik and their colleagues made up. a' composite report covering the use of freezing, oh 82 patients. They found that 88 per cent of the patients showed improvement after the treatment. . The complications included hemorrhage in seven patients and development of new gastric ulcers in four. One patient died several days after the treatment, but the death was. believed-caused by a heart attack,and not related to 'the freezing. "The .improvements were dramatic enough to justify the use | of freezing/* Dr« McHardy re-" nnrtpci "We think the irnnaedi- or- tne ate results are comparable to 1 .perior to what Is achieved with other medical and surgical means./' Urges, Caution But Dr. McHardy emphasized a word of caution. "We do not believe the procedure should be in untrained hands/ he said, ''The individual using it should have had the benefit of work with animals and in the laboratory' before making application clinically, : "Unfortunately, a lot of- the equipment is in un hands/' - ■• ■ - He warned that the procedure should not be attempted on an out-patient basis. "We,feel that it requires hospitalization of the patient, preferably for at least 72 hours/' he added. Training Needed "The team performing the procedure Should be trained properly, not only in introducing the balloon and tube and handling the machinery, but also in controlling the patients' temperature and in handling any emergency which might be created by the rapid and significant change in the body physiology/' He said freezing "is not a procedure for the management of the routine, uncomplicated duodenal nicer. It should be reserved for the refractory case that is established by X-ray and is free of -the; complications of obstruction,: hemorrhage or reo "-' "It b _*e reserved for- patients who are candidates for -surgery/' Dr. McHardy said most of the-work with the technique has , been done/ by surgeons and gas-tor-enterologists, "It should be a team effort/* he cautioned. Involves Risk He said there is a hazard in inept introduction of the bal= loons and generally the procedure "involves as much risk as , surgery/1 '" " Dr. Atik has been studying the temperature attained in the stomach lining with the aid of an implanted thermometer. He' has discovered that the freezing of the stomach wall in animals is patchy. One section of the wall may be frozen solidly, while another section will be at a temperature the equivalent of as much as 45 degrees Fahrenheit, well above freezing. The LSU scientists will continue working with animals under a grant from the National Institute of Health. Dr. McHardy said, one of tfa@ purposes of the three-year stu-dy is to determine- whether there is any damage "to other organs of the body. And -the .. l also are seeking to leam whether the freezing has a physiological effect, or is beneficial only because of a psychological impact on the patient,
