BACKGROUND: Little is known about the effect of passing time on risk of resection among @entity1 with @entity1744 . We sought to provide a benchmark of the relationship of time from symptom onset to surgical treatment on the need for resection in @entity1 with @entity1744 . STUDY DESIGN: We performed an observational study of @entity1 with surgically treated @entity1744 at an inner-city urban tertiary referral center and a municipal hospital. @entity1 were sampled randomly retrospectively (n=60), and prospectively (n=81), for a final sample of 141. Detailed clinical and time data were abstracted from medical records including out-of-hospital examinations. Risk of resection was calculated using actuarial life table methods. Linear regression was used to determine factors affecting time to treatment. RESULTS: All @entity1 were treated surgically for obstruction; 45% underwent resection. Resected @entity1 had longer (11 days versus 8 days; p=0.01) and more complicated (31% versus 14% in ICU; p=0.01) hospital stays. The risk of resection was 4% among @entity1 with 24 hours of unresponsive symptoms; it increased to 10% to 14% through 96 hours, then dropped slightly but did not disappear. @entity1 treated first with a tube had longer times between first examination and operation, system-time (40.6 hours versus 10.2 hours; p=0.0007), but this was not associated with an increased resection risk. System-times were shorter among @entity1 seen first in the emergency department (median: 25.7 hours versus 59.7 hours; p=0.0001). CONCLUSIONS: Physicians should be cautious in postponing surgery beyond 24 hours in @entity1 with unresponsive symptoms from @entity3885 . The risk of resection rises dramatically, remains elevated through 96 hours of unresolved symptoms, then declines but does not disappear.
