Bowel Obstruction, Causes, Signs and Symptoms, Diagnosis and Treatment.

How do you tell if it's constipation or a blockage?

You know it's a blockage, not just constipation, if you have severe, cramping abdominal pain that comes in waves, significant bloating, vomiting, and an inability to pass gas or stool, requiring immediate medical help; whereas constipation involves infrequent, hard stools with less severe pain, often relieved by bowel movements, and the ability to pass gas. The key difference is the intensity and combination of symptoms, especially the inability to pass gas, signaling a more serious obstruction.
 

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.

What is the gold standard test for intestinal obstruction?

To confirm a diagnosis of intestinal obstruction, your doctor may recommend an abdominal X-ray. However, some intestinal obstructions can't be seen using standard X-rays.

What happens if a bowel obstruction is left untreated?

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 can be mistaken for a bowel blockage?

Clinicians should consider a foreign body or bezoar in the differential for unexplained intermittent bowel obstruction symptoms. Phytobezoars can occur from undigested plant or food material, and generally require endoscopic evaluation for diagnosis and potential treatment.
