Abstract：Objective To investigate the recurrence feature of aircrew's peptic ulcer,and to provid scientific evidence for prevention and treatment of peptic ulcer. Methods Twenty-six cases of newly diagnosed peptic ulcer aircrew were divided into two groups according to the following six aspects:age, flight time, position of ulcer, air plane species, duty of flying, and helicobacter pylori(Hp) infection rate. The recurrence rates of peptic ulcer in these six aspects were compared respectively. Results Twenty-six cases of newly diagnosed peptic ulcer aircrew were followed-up for(26±3.5)months, 4 cases were high-quality heal (15.4%), 19 cases were mid-quality heal(73.1%), 3 cases were low-quality heal(11.5%). 6 cases recurred among 26 cases:1 case was gastric ulcer,3 cases were duodenal ulcer, 2 cases were complex ulcer. There was not statistically significant difference in age between the group of older than 30-year-old and the group of younger than 30-year-old(P>0.05). While there were statistically significant difference in the part of flight time, position of ulcer, air plane species,duty of flying, Hp infection(all P<0.05). The recurrence rate of peptic ulcer in the group of long-time flying was higher than that in the group of short-time flying;the recurrence rate of peptic ulcer in the group of battleplane was higher than that in the group of other types of aircraft;the recurrence rate of peptic ulcer in the group of pilot was higher than that in the group of other personnel;the recurrence rate of peptic ulcer in the group of duodenal ulcer was higher than that in the group of gastric ulcer;the recurrence rate of peptic ulcer in the group of Hp positive was higger than that in the group of Hp negtive. Conclusions The recurrences of peptic ulcer in aircrew are concerned with multiple factors. The major factors include:flying for a long time, pilots of battle plane, duodenal ulcer, helicobacter pylori(Hp) infextation, and so on. Reconstruction of psychological health and eradication of helicobacter pylori are important programs for the prevention and treatment of peptic-ulcer in the aircrew.
