Abstracts. Surgery. Failures after resection for gastric and duodenal ulcers. Prof. N. Haberer (Zntrbl. F. Chir. 1930, No. 2), having extensive experience in gastric resections (2310 cases), analyzes the failures that may occur. First of all, the author gives incorrect indications for resection, such as ulcerative gastritis, cholecystitis and diseases of other organs, mistaken for a stomach ulcer. Failures can occur with the correct indications for resection, i.e., callous, perforated ulcers, when insufficient resection is performed, although the author is against large, extensive resections. For a satisfactory outcome, it recommends resecting the antrum and pylorus. The author attaches great importance to the dietary sequential treatment and regimen in the sense of hard work, if they are not followed, there can be failures.
