Small Bowel Obstruction
Small bowel obstruction (SBO) is a significant and potentially life-threatening condition that requires prompt diagnosis and treatment. It occurs when the small intestine is partially or completely blocked, preventing the normal passage of digestive contents. Let us explore the symptoms, causes, diagnostic methods, and treatments for small bowel obstruction, providing a comprehensive understanding of this gastrointestinal issue.
What Is Small Bowel Obstruction?
Small bowel obstruction refers to a blockage in the small intestine that impedes the normal flow of digestive contents. This condition can lead to severe complications, including tissue death and infection, if not treated promptly.

Get A Second OpinionSymptoms of Small Bowel Obstruction
Recognizing the symptoms of small bowel obstruction is crucial for early diagnosis and treatment. Common symptoms include:
- Abdominal Pain: Often crampy and intermittent, located around the belly button or lower abdomen.
- Vomiting: This can include bile or even fecal matter in severe cases.
- Abdominal Distension: A visible swelling of the abdomen due to trapped gas and fluids.
- Constipation: An inability to pass gas or stool, indicating a complete blockage.
- Diarrhea: In cases of partial obstruction, diarrhea may occur.
- Fever: A sign of infection or complications such as peritonitis.
These symptoms can vary in intensity and onset, making it essential to seek medical attention if you suspect a bowel obstruction.
Causes of Small Bowel Obstruction
Various factors can lead to small bowel obstruction, including:
Adhesions
Post-surgical adhesions are the most common cause of SBO. These are bands of scar tissue that form after abdominal surgery, leading to a narrowing or blockage of the intestine.
Hernias
Hernias occur when a part of the intestine protrudes through a weak spot in the abdominal muscles, potentially causing a blockage.
Tumors
Both benign and malignant tumors can obstruct the small intestine.
Inflammatory Bowel Diseases
Conditions such as Crohn's disease can cause inflammation and strictures, leading to obstruction.
Foreign Bodies
Ingested objects, gallstones, and other foreign bodies can cause blockages.
Diagnosis of Small Bowel Obstruction
Accurate diagnosis is essential for effective treatment. Medical professionals use several methods to diagnose small bowel obstruction:
Physical Examination
A thorough physical examination, including checking for abdominal distension and tenderness, is the first step.
Imaging Studies
- X-rays: Abdominal X-rays can reveal air-fluid levels and distended loops of bowel.
- CT Scans: Computed tomography (CT) scans provide detailed images of the bowel and can help identify the location and cause of the obstruction.
- Ultrasound: Useful in certain cases, especially for children and pregnant women.
Laboratory Tests
Blood tests can help assess the severity of the obstruction and identify any complications, such as infection or electrolyte imbalances.
Treatment for Small Bowel Obstruction
The treatment approach depends on the severity and cause of the obstruction.
Non-Surgical Management
In some cases, non-surgical methods can relieve the obstruction:
- Nasogastric Tube: A tube inserted through the nose into the stomach to remove gas and fluids, relieving pressure.
- Intravenous Fluids: To prevent dehydration and correct electrolyte imbalances.
- Medications: Pain relievers, anti-nausea medications, and drugs to stimulate bowel movements.
Surgical Treatment
Surgery may be necessary for complete obstructions or when non-surgical treatments fail:
- Laparoscopy: A minimally invasive procedure using small incisions and a camera to remove the blockage.
- Laparotomy: A more extensive surgery involving a larger incision to access the intestine and remove the obstruction.
Postoperative Care
Post-surgery, patients require careful monitoring and follow-up care to ensure proper healing and prevent recurrence.
Managing Intestinal Blockages
Preventive measures and lifestyle modifications can help manage and reduce the risk of intestinal blockages:
Dietary Changes
A diet rich in fiber can promote healthy bowel movements and prevent constipation, reducing the risk of obstructions.
Regular Exercise
Physical activity stimulates digestion and prevents the formation of adhesions and hernias.
Medical Follow-ups
Regular check-ups with a healthcare provider can help monitor and manage conditions that predispose individuals to SBO, such a

If left untreated, small bowel obstruction can lead to severe complications:
Tissue Death
A prolonged blockage can restrict blood flow to the intestine, causing tissue death and potentially leading to perforation and peritonitis.
Infection
Bacterial overgrowth and stagnation of intestinal contents can result in infections, including sepsis.
Recurrence
Even after successful treatment, there is a risk of recurrence, especially if the underlying cause is not addressed.
Small Bowel Obstruction ICD 10
The International Classification of Diseases, Tenth Revision (ICD-10) provides specific codes for small bowel obstruction, aiding in accurate diagnosis and treatment documentation. The relevant codes include:
- K56.0: Paralytic ileus
- K56.1: Intussusception
- K56.2: Volvulus
- K56.5: Intestinal adhesions bands with obstruction (postoperative)
- K56.6: Other and unspecified intestinal obstruction
Frequently Asked Questions
1. What are the symptoms of small bowel obstruction?
Symptoms include severe abdominal pain, vomiting, bloating, and constipation, often accompanied by an inability to pass gas.
2. What causes small bowel obstruction?
Caused by adhesions, hernias, tumors, or inflammatory conditions like Crohn’s disease that block the passage of contents through the intestines.
3. How is small bowel obstruction diagnosed?
Diagnosed through physical examination, imaging tests like X-rays or CT scans, and sometimes a barium swallow test to assess the blockage.
4. How is small bowel obstruction treated?
Treatment includes surgery to remove the blockage, medications to relieve symptoms, and sometimes non-surgical options like bowel rest.
5. How can intestinal blockages be managed long-term?
Managing involves addressing the underlying cause, adhering to dietary restrictions, and regular follow-ups with a doctor to monitor intestinal health.
