In this work, the authors support the therapeutic validity of gastric-duodenal resection in urgency surgery. This study has been made on 479 cases observed during the last 21 years (1957-78). In 58 of them we have made a sinking of ulcer, in 421 patients we have made, immediatly, a gastric-duodenal resection with B II technique. On the base of the good obtained results, the authors conclude that the contro-indications to this operation (age, general conditions of patient, old pierce, etc.) that were accepted by the most surgeons up to few years ago, must considered of secondary importance.
