What is the 3 6 9 rule for bowel obstruction?

The 3-6-9 rule is a mnemonic for identifying bowel dilation on imaging (X-ray/CT) in suspected intestinal obstruction, stating normal bowel diameters are typically <3 cm for the small bowel, <6 cm for the colon, and <9 cm for the cecum, with values exceeding these suggesting obstruction or ileus. A related rule notes high rupture risk at >6cm (small bowel) and >9cm (colon), with the cecum >12cm being critical. This rule helps radiologists spot dilated loops and differentiate obstruction from paralytic ileus, often seeing more colon gas in ileus and more small bowel gas in obstruction, plus late signs like no rectal air.
