RECENT REPORTS including those of double-blind studies concerning the efficacy of gastric freezing as treatment of patients with medically refractory duodenal ulcers are conflicting.

The report of Allcock and co-authors4 suggests that the numbers of chief and parietal cells are temporarily decreased after freezing while the reports of Owens,5 Nabseth,6 and Gilat7 and their respective co-workers
