Abstract
Clinical appraisal of results of operations for chronic duodenal ulcer is beset with peculiar difficulties, such as variations in the selection of patients, problems in interpreting equivocal operative findings, differences in operative technics, and subjective values in appraisal of end results. A comparison of two types of operation in a personal series is presented, which avoids some of these variables; the series includes 100 patients who underwent vagotomy-posterior gastrojejunostomy and 100 patients who underwent vagotomy-hemigastrectomy.
