Obstruction of gastric outflow is a serious and frequent complication of peptic ulceration. In the September Archives of Surgery,1 Kozoll and Meyer report approximately 900 patients treated for obstruction at Cook County Hospital in the past 20 years. This number is 10.5% of the patients with verified peptic ulcer seen there in the same interval, an incidence of obstruction which confirms the findings of other investigators. Moody and coworkers,2 for example, reported that over 25% of their 242 patients with duodenal ulcers experienced pyloric obstruction.
Kozoll and Meyer analyze data derived from the history, physical examination, and laboratory test results of their patients and compare the figures with those from similar analysis of patients with peptic ulceration complicated by perforation and by hemorrhage. In patients with obstruction the duration of symptoms is much longer. Epigastric pain is the most common symptom. Emesis is also very common and, as
