Intestinal blockages can show symptoms rapidly, often within a few hours for a small bowel obstruction, or gradually over several days/weeks for large bowel blockages. Severe pain, vomiting (sometimes green bile), bloating, and inability to pass gas are immediate warning signs that require emergency medical attention.

How quickly does an intestinal blockage occur?

A bowel obstruction can begin suddenly or may progress gradually over several weeks or days. 2 Before a complete bowel obstruction develops, you may experience some warning signs caused by a partial bowel obstruction. Symptoms that often precede a partial or complete bowel obstruction include: Decreased appetite.

What is the 3 6 9 rule for intestinal 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.

What mimics a bowel obstruction?

Intestinal pseudo-obstruction occurs when nerve or muscle problems slow or stop the movement of food, fluid, air, and waste through the intestines.

Would a CT scan show an impacted bowel?
