Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion.[2][5] Either the small bowel or large bowel may be affected.[1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas.[1] Mechanical obstruction is the cause of about 5 to 15% of cases of severe abdominal pain of sudden onset requiring admission to hospital.[1][2]

Causes of bowel obstruction include adhesions, hernias, volvulus, endometriosis, inflammatory bowel disease, appendicitis, tumors, diverticulitis, ischemic bowel, tuberculosis and intussusception.[1][2] Small bowel obstructions are most often due to adhesions and hernias while large bowel obstructions are most often due to tumors and volvulus.[1][2] The diagnosis may be made on plain X-rays; however, CT scan is more accurate.[1] Ultrasound or MRI may help in the diagnosis of children or pregnant women.[1]

The condition may be treated conservatively or with surgery.[2] Typically intravenous fluids are given, a nasogastric (NG) tube is placed through the nose into the stomach to decompress the intestines, and pain medications are given.[2] Antibiotics are often given.[2] In small bowel obstruction about 25% require surgery.[6] Complications may include sepsis, bowel ischemia and bowel perforation.[1]

About 3.2 million cases of bowel obstruction occurred in 2015 which resulted in 264,000 deaths.[3][7] Both sexes are equally affected and the condition can occur at any age.[6] Bowel obstruction has been documented throughout history, with cases detailed in the Ebers Papyrus of 1550 BC and by Hippocrates.[8]
