	abstract = {We examined epidemiological aspects of Ascaris-induced intestinal obstruction (AI-IO) through analysis of published reports on the subject. In 9 studies of >=100 patients admitted to hospital due to ascariasis, intestinal obstruction was the single most common complication and accounted for 38{\textendash}87{\textperiodcentered}5\% of all complications (weighted mean 72\%). The proportion of intestinal obstruction caused by ascariasis was identified in 14 studies from 7 countries with varying degrees of endemic ascariasis. Using relevant data on the duration of the study, the number of beds in the reporting hospital, and the number of hospital beds/1000 population in the area, the number of cases of AI-IO/year/1000 population was estimated from 11 studies. Both the proportion of AI-IO (range 0{\textendash}0{\textperiodcentered}71) and the number of cases of AI-IO/year/1000 population (range 0{\textendash}0{\textperiodcentered}25) were significantly related, in a non-linear manner, to the local prevalence of ascariasis (range 0{\textperiodcentered}01{\textendash}0{\textperiodcentered}92). In 12 studies of >=30 patients with AI-IO, the case fatality rates ranged from 0 to 8{\textperiodcentered}6\% (weighted mean 5{\textperiodcentered}7\%). The mean age of patients with AI-IO was <=5 years in 6 of 7 studies in which age was specified.},
