Design outcomes

Primary

Measure	Time frame
Validation of the Wassmer 8-item score for detecting bowel ischemia requiring surgical intervention in patients with acute adhesive small bowel obstruction, with treatment decision (operative vs. conservative) guided by the score. Each patient evaluated through eight item score which includes the following (age 70 years and older ,first attack of small bowel obstruction,absence of bowel movement for 3 days and more ,abdominal guard or rigidity,CT transition zone ,CT lack of bowel wall enhancement ,CT amount of IPFF 500 and more ml patients scored 4 and more explored immediately and others scored less than 4 underwent conservative management	—
