Bowel Blockage and Diet
Surgical procedures involve removing the blockage or repairing or removing the damaged portion of the intestine. Doctors often diagnose children with a suspected ileus using an ultrasound scan. Ultrasound scans typically show a coiled area in the intestine when intussusception is present.
Gastric and small-intestine recovery is believed to occur first, followed by the return of colonic function. Uncomplicated POI is a self-limiting process.1,6 A delayed return to normal function is painful for the patient and costly for the health care system. Thus, the common manifestations of small-bowel ileus include nausea and vomiting, cramps, and bloating. Ileus needs to be distinguished from other causes of abdominal pain, distension, and nausea/vomiting.
Considerations for surgery
Without treatment, the ileus can perforate or tear the intestine. This causes bowel contents — which have high levels of bacteria — to leak into areas of your body cavity. This means no food material, gas, or liquids can get through.
Individuals can improve their outlook and reduce the risk of complications by understanding the symptoms. It is essential to seek prompt medical treatment as soon as symptoms appear. In some cases, a surgeon may need to remove a person’s entire intestine. They create an opening in the abdomen, called a stoma, allowing stool to pass from the intestine into a pouch that collects stool. If medication or dietary changes do not resolve the ileus, or if the blockage is severe, then a person may need surgery. Conditions such as Crohn’s disease and diverticulitis can cause a partial intestinal block.
Complications
Patients with a peritoneal tumor burden and the new onset of ileus should be evaluated at least with a CT of the abdomen to determine the cause of ileus and assess the extent of neoplastic disease. If pharmacotherapy brings no improvement in 2 to 3 days, endoscopic deflation and insertion of a decompressive tube in the right hemicolon is recommended . Drug-induced ileus—due to the consumption of opioids, neuroleptic drugs, etc. Single procedure—The malignant stenosis is resected together with the proximal dilated segment with attention to clean oncological margins, and a primary anastomosis is created without colostomy.
If you’re going to have surgery, the possibility of getting an ileus should be considered. Two of the most severe complications are necrosis and peritonitis. An ultrasound is more commonly used to identify an ileus in children.
If constipation nonetheless arises, further help is available in the form of a therapeutic algorithm in the German S2k guideline on chronic constipation in adults . Postoperative ileus is a frequent complication of surgery, particularly visceral surgery. It puts an additional financial burden on the U.S. health-care system amounting to some 1.5 billion dollars per year. The decision whether to operate is not always easy, even for experienced surgeons.
Bowel obstruction is a mechanical blockage of intestinal contents by a mass, adhesion, hernia, or some other physical blockage. These two diseases may present similarly, but treatment can be very different depending on the underlying pathology. Treating the infection, electrolyte abnormalities, decreasing opiate use, can all potentially decrease the durability of an ileus.
There's nothing physically blocking the passage of food in your intestines. Sometimes the entire digestive tract is affected, and sometimes ileus is localized in a particular bowel loop near the site of an injury or inflammation. Ileus is usually a temporary reaction of your body to trauma, such as surgery or infection. However, chemical factors, including medications, metabolic disturbances and electrolyte imbalances can also be at fault. The clinical manifestations of ileus and their degree of severity depend to a large extent on the site of the blockage.
Patients with POI may experience a painful and distended abdomen, vomiting, toxemia, and dehydration. Although the lumen is not occluded, peristalsis fails when the intestinal contents back up, resulting in watery diarrhea. Pain rarely has the classic colicky pattern present in mechanical obstruction.9 Bowel sounds are minimal or absent. Abdominal tenderness generally is present only when the cause of the ileus is inflammation. The cause of ileus appears to be multifactorial .1,6 POI may result from the use of postsurgical opioid pain relievers (e.g., morphine), which can slow or inhibit normal motility. Opioid analgesics relieve pain by blocking pain signals through stimulation of opioid receptors located on the surface of the nerves that transmit these signals.

Medications to promote peristalsis may help reboot your bowel function if it doesn’t recover soon enough on its own. You’ll avoid eating by mouth until your bowel function has returned.
Managing and Treating Ileus
List the types of functional ileus and know how they should be treated. There are, however, several risk factors that have been shown to increase the likelihood and endurance of an ileus. Causes for Severe Abdominal Pain & Swelling Learn More Since ileus is often caused by injury, surgery, or a medical condition, little can be done to prevent it, according to the University of Southern California. It is important to follow your physician's recommendations regarding diet once your ileus has resolved. Generally, no certain diet is ordered and you may be able to resume your normal diet. When your intestine stops making those wave-like movements for a while, it's called ileus.
