Description

Purpose : Predictor of bowel resection were examined in patients with incarcerated obturator hernias.<BR>Materials and Methods : Fifty patients who underwent emergent surgery for incarcerated obturator hernias from June 1999 to May 2016 were classified into two groups (did and did not require bowel resection), and predictors of bowel resection were retrospectively evaluated. Patient background characteristics, clinical signs, and preoperative examination findings were investigated.<BR>Results : Twenty-two patients required bowel resection. Nausea and/or vomiting, serum CRP values, interval between symptom onset and surgery, and postoperative length of stay were significantly different between the two groups. The interval between symptom onset and surgery was identified as an independent predictor of bowel resection (P<0.0001) on multivariate analysis. Moreover, on ROC curve analysis, the cut-off period for requiring surgical resection was <2 days (sensitivity, 95.5% ; specificity, 67.9% ; area under the curve, 0.825).<BR>Conclusion : The interval between symptom onset and surgery is a good predictor of the need for intestinal resection and a reference for selecting the appropriate procedure for incarcerated obturator hernias.
