Ileus is a medical condition characterized by the obstruction of the intestines. It occurs when there is a lack of movement in the muscles of the intestines, leading to a buildup of contents and gas. This can result in symptoms such as abdominal pain, bloating, vomiting, and constipation. • Ileus can be caused by various factors, including: • 1. **Surgery**: After abdominal surgery, the intestines may temporarily stop working properly. • 2. **Infections**: Certain infections, such as peritonitis or gastroenteritis, can lead to ileus. • 3. **Medications**: Some drugs, especially opioids used for pain relief, can slow down bowel motility. • 4. **Electrolyte imbalances**: Abnormal levels of potassium, calcium, or other electrolytes can affect intestinal function. • 5. **Trauma**: Injuries to the abdomen or pelvis can result in ileus. • 6. **Hernias**: A hernia can cause a blockage in the intestines. • 7. **Tumors**: Benign or malignant growths can obstruct the intestines. • 8. **Other medical conditions**: Conditions like Crohn's disease, diverticulitis, or volvulus can lead to ileus. • Ileus can be categorized into different types based on its underlying cause or location. Some common types include: • 1. **Postoperative Ileus**: Occurs after abdominal surgery due to handling of the intestines during the procedure. • 2. **Paralytic Ileus**: Results from a lack of intestinal muscle movement, often due to factors like surgery, infection, or medications. • 3. **Mechanical Ileus**: Caused by a physical obstruction in the intestine, such as a tumor, hernia, or adhesions (bands of scar tissue). • 4. **Functional Ileus**: Not caused by a physical obstruction but by a disturbance in the normal propulsive movements of the intestines. This can be due to electrolyte imbalances, medications, or other medical conditions. • 5. **Neonatal Ileus**: A condition seen in newborns, often associated with conditions like cystic fibrosis or Hirschsprung's disease, where there's a lack of nerve cells in parts of the intestine. • Ileus can present with a variety of signs and symptoms, which may include: • 1. **Abdominal Pain**: Often described as cramping or a constant dull ache. • 2. **Abdominal Distension**: Swelling or bloating of the abdomen due to the buildup of gas and fluids. • 3. **Vomiting**: Nausea and vomiting may occur as the intestine becomes distended. • 4. **Constipation**: Difficulty passing stool or a complete absence of bowel movements. • 5. **Lack of Bowel Sounds**: On auscultation, there may be reduced or absent bowel sounds due to decreased intestinal activity. • 6. **Nausea**: A feeling of queasiness or the urge to vomit. • 7. **Loss of Appetite**: A decreased desire to eat or drink. • 8. **Tenderness**: The abdomen may be tender to touch in certain areas. • Diagnosing ileus typically involves a combination of clinical evaluation and diagnostic tests. Here are some common diagnostic approaches: • 1.Medical History and Physical Examination • 2.Abdominal X-ray: This imaging test can help visualize any blockages or air-fluid levels in the intestines, which can be indicative of ileus. • 3.CT Scan • 4.Blood Tests • 5.Barium Enema or Upper GI Series • 6.Colonoscopy or Endoscopy • Surgical techniques for ileus aim to address the underlying cause of the obstruction or dysfunction in the intestines. Here are some common surgical approaches and techniques used: • 1.Laparotomy: This is a traditional open surgery where a large incision is made in the abdomen to access and address the intestines directly. • 2.Laparoscopic Surgery: Also known as minimally invasive surgery, this technique involves making several small incisions through which specialized instruments and a camera are inserted. The surgeon views the inside of the abdomen on a monitor and performs the necessary interventions, which may include removing adhesions, resecting a segment of the intestine, or performing anastomosis. • 3.Adhesiolysis: In cases where adhesions are causing the obstruction, the surgeon carefully separates or removes the scar tissue to free up the intestines and restore normal function. • 4.Bowel Resection and Anastomosis: If a portion of the intestine is damaged or necrotic, it may be surgically removed (resected). The healthy ends of the intestine are then rejoined (anastomosed) to restore continuity and function. • 5.Stoma Creation: In situations where the intestine cannot be reconnected or when a temporary diversion is needed, a stoma (an opening) may be created on the abdominal wall. Types of stomas include colostomy (connecting the colon to the abdominal wall) or ileostomy (connecting the ileum). • 6.Bowel Decompression: In cases of severe distension, a surgical procedure may be performed to insert a tube into the intestine to relieve pressure and remove gas or fluids. • 7.Lysis of Volvulus: If ileus is caused by a volvulus (twisting of the intestine), the surgeon may perform a procedure to untwist the affected segment and secure it to prevent recurrence. • #surgicalexcellence • #surgeryday • #subscribe
