What is ileus and what causes it?
What is mechanical ileus? Mechanical ileus is an ileus in which the bowel becomes impassable due to an external obstruction (eg strangulation) or if an obstruction occurs in the intestinal lumen. There are two forms of mechanical ileus.
What are the symptoms of mechanical ileus?
Mechanical ileus is that due to adhesions, ischemia, tumor, or stone and requires prompt decompression of the bowel to prevent perforation. Symptoms. The principal symptoms of ileus are abdominal pain and distention, constipation, and vomiting in which the vomitus may contain fecal material.
What is the difference between an ileus and an intestinal obstruction?
Unlike an ileus, a mechanical intestinal obstruction results from the physical blockage of the intestines. It is often a complete obstruction and is typically the result of conditions that cause sliding ( intussusception) or twisting ( volvulus) of the intestines onto itself, ultimately cutting off blood vessels and causing tissue death.
What is the difference between mechanical LEUS and low ileus?
Pain in the mechanical leus is convulsive, occurs at short intervals in the high ilus, whereas in the low ileus in the left colon it occurs very rarely. The patient feels a flow through the intestine.
What causes a mechanical ileus?
Mechanical ileus Possible causes include: External compression (adhesions, hernia) Changes in the bowel wall (tumor, inflammation/infection) Blockage of the lumen (coprostasis, intussusception).

Is an ileus the same as bowel obstruction?
Ileus and intestinal obstruction have similarities. However, ileus results from muscle or nerve problems that stop peristalsis, while an obstruction is a physical blockage in the digestive tract. However, a type of ileus known as paralytic ileus can cause a physical block due to a food buildup in the intestines.

What is an ileus?
An ileus is the temporary slowing of digestive tract mobility which can lead to a buildup and blockage in the digestive tract. The smooth muscle of the digestive tract moves in a series of waves called peristalsis, pushing the contents of food or drink from the esophagus through the large intestine. Disruptions in peristalsis can occur anywhere throughout the digestive tract and can range from acute to chronic. Severe acute peristaltic disruptions, also known as paralytic ileus, can lead to a functional intestinal obstruction in which the muscles fail to contract and can cause a buildup of gas and other liquid or solid contents. Chronic severe peristaltic disruptions are known as a pseudo-obstruction and result from chronic neuromuscular problems. Pseudo-obstructions can lead to persistent life-threatening functional intestinal obstructions.
What is paralytic ileus?
Paralytic ileus is a severe form of ileus that occurs when peristalsis has been significantly reduced or stopped, leading to a buildup of stomach contents in part of the intestine. Risk factors for paralytic ileus include abdominal surgery and infection or inflammation of various parts of the digestive tract, such as the stomach or intestines (e.g. gastroenteritis ), pouches in the intestines (e.g. diverticulitis ), or the pancreas (e.g. pancreatitis ).
What is meconium ileus?
Meconium ileus is a severe form of ileus that occurs in infants and may be a sign of cystic fibrosis, which is a genetic condition affecting the lungs and digestive systems . Meconium refers to a dark green stool passed within the first 24 hours of life by a newborn. It can become abnormally thick and sticky, especially in those with cystic fibrosis. The thick meconium can then cling to the intestinal wall, impeding its movement through the digestive tract, and eventually causing meconium to build up and block the last part of the small intestine.
What is gallstone ileus?
More accurately referred to as a mechanical intestinal obstruction , gallstone ileus occurs due to the physical blockage of the small intestine by a gallstone. Large gallstones can enter the small intestine through an opening that forms between the gallbladder and intestinal wall, known as a cholecystoduodenal fistula. Gallstone ileus is a rare complication of cholelithiasis (the formation of gallstones) and those at higher risk include older adults with comorbid conditions like diabetes, chronic lung disease, or heart failure.
How do you diagnose an ileus?
Diagnosis begins with an assessment of the individual’s medical history. The severity of signs and symptoms often depends on the presence of intestinal obstruction and may include abdominal pain, bloating, loss of appetite, feeling of fullness, nausea, vomiting, and inability to pass gas or stool. During an abdominal assessment, healthcare providers may hear reduced bowel sounds.
How do you treat an ileus?
Treatment for an ileus focuses on bowel rest by limiting oral intake and discontinuing medications that may be causing the ileus. In cases where oral fluids are not tolerated, rehydration with IV fluids may be necessary . If severe nausea and vomiting is present, nasogastric tube decompression can be performed by inserting a tube from the nose to the stomach, in order to relieve pressure caused by bloating and buildup of stomach contents.
What are the most important facts to know about ileus?
With paralytic ileus, peristalsis is significantly reduced or stopped, leading to a functional intestinal obstruction and consequent buildup of stomach contents in part of the intestine. Another type of ileus is meconium ileus, commonly seen in newborns with cystic fibrosis, in which thick, sticky stool (meconium) sticks to the intestinal wall and becomes trapped in the small intestine. Gallstone ileus (more accurately known as a mechanical intestinal obstruction) refers to a large gallstone creating a blockage in a portion of the small intestine. Abdominal or pelvic surgery are the most common causes of an ileus. Other factors that can slow digestive tract mobility include certain medications, inflammation, infection, pain, and metabolic abnormalities. Signs and symptoms of an ileus can include abdominal pain, bloating, loss of appetite, and the inability to pass gas or stool. Diagnosis focuses on a review of medical history and a physical assessment. Imaging tests such as an abdominal X-ray, CT scan, MRI, ultrasound imaging, or barium enema may also be used to diagnose the ileus. Treatment typically involves bowel rest, rehydration, and discontinuing offending medications.

What happens when you eat solid food?
If people continue to eat solid food, it can lead to a backlog of food particles, which may cause full or partial obstruction of the intestines. An ileus most commonly occurs after abdominal or pelvic surgery.
Why is a CT scan more accurate than an X-ray?
A CT scan provides more detail than standard X-ray images. These scans are more likely to highlight an ileus because they show the intestines from different angles. Sometimes, a person swallows a special dye that creates a clearer image.

How to treat ileus?
Treatment options for an ileus include waiting for the ileus to resolve, making dietary changes, or adjusting medication use. Sometimes, surgery is necessary. The treatment will depend on the severity of the ileus and its underlying cause.
Why is ileus common after surgery?
An ileus is common after surgery because people are often prescribed medication that can slow intestinal movement. This is a type of paralytic ileus. In this instance, the intestine isn’t blocked. Rather, it isn’t moving properly. The result is little or no movement of digested food through your intestines.
What causes a traffic jam in the intestines?

How long does ileus last after surgery?
Due to the delayed refeeding syndrome seen after an ileus, postoperative ileus has a large economic impact in the United States alone.[3] An ileus usually manifests itself from the third to the fifth day after surgery and usually lasts 2 to 3 days with the small bowel being the quickest to return to function (0 to 24 hours), followed by the stomach (24 to 48 hours), and lastly the colon (48 to 72 hours). [2][4][5] A prolonged ileus is diagnosed if the ileus exceeds 2 to 3 days with the continued absence of obstruction signs. [6]
What is ileus in medicine?
Ileus refers to the intolerance of oral intake due to inhibition of the gastrointestinal propulsion without signs of mechanical obstruction. The diagnosis is often associated with surgery, medications, trauma, peritonitis, or severe illness. Mechanical obstruction has to be ruled out, and the diagnosis of ileus is dependent on radiographic evidence, usually on a CT scan or small bowel series. This activity reviews the evaluation and management of an Ileus and highlights the role of the interprofessional team in improving care for patients with this condition.
What is the mainstay of ileus management?
The mainstay management of ileus is prevention, followed by appropriate diagnosis, and conservative/expectant management. At times this can be difficult and often requires all aspects of the healthcare system to participate in its prevention. Encouraging ambulation, multimodal pain regimens, ERAS protocols, and monitoring oral intake all are difficult for any person/team to monitor.

[1][2] 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.
What is the treatment for ileus?
Once diagnosed, treatment is supportive (IV fluids, NG decompression) with the management of precipitating factors (opiates, sepsis). Postoperative ileus is common, but steps can be taken to help prevent it, especially in an outpatient/elective setting (ERAS protocols, ambulation, laparoscopy).
How to treat ileus?
Historically these treatments were thought to lower complications and improve outcomes, but a recent review of the evidence shows otherwise.[15] Chewing gum has been studied and seems to be a cheap, well-tolerated way to potentially help with ileus as it stimulates the cephalocaudal reflex, which promotes peristalsis and inhibits inflammation. [19][20] Unfortunately, these are the only options we currently have as pharmacologic agents have been ineffective. Many have been studied in the past with inconsistent outcomes, including erythromycin, sympathetic inhibitors (guanethidine), parasympathetic stimulators (neostigmine), hormonal agents (cholecystokinin, motilin).
What is the responsibility of a surgical provider to prevent ileus?
Prevention of ileus is the responsibility of both the patient and healthcare providers, including, nurses, pharmacologists, and physical/occupational therapists. Encouraging ambulation, enhanced recovery after surgery (ERAS) protocols, and educating the patient on their importance and benefits should improve patient understanding and compliance.

Why does my bowel blockage?
Blockage may be caused by something blocking the inside of the tube or something that stops the intestine from working well . Most small bowel blockages are due to scar tissue.
What happens when your bowel is blocked?
When the bowel is blocked, food and liquid cannot pass through. Over time, food, liquid, and gas build up and cause pressure and pain. Some obstructions, when left untreated, can cut off the flow of blood to the intestine. This can lead to death of the intestine tissue and serious illness. Mechanical Bowel Obstruction.
