The incidence of operations for peptic ulcer increased in Singapore during the period 1951 to 1980 (males from 12.1 to 40.0 per 100,000 per year; females from 1.1 to 13.2 per 100,000 per year). This increase is due to an increase in surgery for both perforated and non-perforated ulcers. While an increase in elective ulcer surgery may be due to a number of factors, the increase in surgery for perforated ulcers suggests that peptic ulcers have increased in frequency over this period. The incidence of peptic ulcer surgery amongst the Chinese was higher than that amongst the Malays and the Indians. For males, however, this difference between the Chinese and the Malays became less marked over the thirty years. In contrast, the difference between the Chinese and the Indians remained constant.
1951年至1980年期间，新加坡消化性溃疡手术的发病率有所上升（男性从每年每10万人中的12.1例增至40.0例；女性从每年每10万人中的1.1例增至13.2例）。这种增长是由于穿孔性溃疡和非穿孔性溃疡手术的增加。虽然择期溃疡手术的增加可能是由于多种因素，但穿孔性溃疡手术的增加表明在此期间消化性溃疡的发病率有所上升。华人中消化性溃疡手术的发病率高于马来人和印度人。然而，对于男性来说，华人与马来人之间的这种差异在三十年里变得不那么明显了。相比之下，华人与印度人之间的差异保持不变。
