Intussusception caused SBO in five patients, and one patient had an internal herniation, while three patients had unremarkable findings. Eight patients were evaluated for intermittent pain with five unremarkable laparoscopies, while 18 patients had intussusceptions as incidental findings. Intussusception length on CT as measured by radiologists O.E. and D.L. predicted acute bowel obstruction (<jats:italic>p<\/jats:italic>\u2009=\u2009.014 and <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). A 100\u00a0mm threshold predicted bowel obstruction with a sensitivity of 80% and 100% and a specificity of 93% and 86% by radiologists O.E. and D.L., respectively.
