Large intestine obstruction, also known as colonic obstruction, is a serious medical condition where the large intestine (colon) is blocked. This blockage prevents the normal movement of digestive contents through the colon, leading to various uncomfortable and potentially dangerous symptoms. Understanding the causes, symptoms, treatments, and preventive measures is crucial for maintaining digestive health and seeking timely medical help when needed.
Anatomy of the Large Intestine
The large intestine is a vital part of the digestive system, responsible for absorbing water and salts from the food remnants and forming stool. It consists of several parts:
- Cecum: The beginning of the large intestine, connecting to the small intestine.
- Ascending Colon: Travels upward on the right side of the abdomen.
- Transverse Colon: Crosses the abdomen from right to left.
- Descending Colon: Travels downward on the left side.
- Sigmoid Colon: An S-shaped section leading to the rectum.
- Rectum: The final section, storing stool before elimination.
- Anus: The opening through which stool exits the body.
Understanding the layout of the large intestine helps in identifying where an obstruction may occur and how it affects digestion.
Large intestine obstruction is a blockage that prevents the normal passage of stool, gas, and digestive fluids through the colon. This blockage can be partial or complete and can occur at any point along the large intestine. When the intestine is blocked, waste materials back up, causing swelling, pain, and other symptoms. If not treated promptly, it can lead to serious complications like infection, perforation (a hole in the intestine), and even life-threatening conditions.
Types of Large Intestine Obstruction
Large intestine obstructions can be categorized based on their cause and location. The main types include:
- Mechanical Obstruction:
- Caused by a physical blockage.
- Examples: Tumors, strictures, or impacted stool.
- Pseudo-Obstruction (Ogilvie’s Syndrome):
- Mimics a blockage without a physical barrier.
- Caused by nerve or muscle problems in the intestine.
- Volvulus:
- Twisting of the intestine, cutting off blood supply.
- Common in the sigmoid colon and cecum.
- Intussusception:
- One part of the intestine slides into another, like a telescope.
- More common in children but can occur in adults.
- Diverticular Disease:
- Formation of small pouches (diverticula) that can block the intestine.
Understanding the type of obstruction helps in determining the appropriate treatment approach.
Causes of Large Intestine Obstruction
Large intestine obstruction can result from various factors. Here are 20 common causes:
- Colon Cancer: Tumors can grow and block the intestine.
- Diverticulitis: Inflammation or infection of diverticula causing swelling or scarring.
- Volvulus: Twisting of the colon causing blockage.
- Intussusception: One part of the intestine slides into another.
- Strictures: Narrowing of the intestine from scar tissue.
- Fecal Impaction: Hardened stool blocks the colon.
- Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease or ulcerative colitis causing inflammation and scarring.
- Hernias: Part of the intestine pushes through a weak spot in the abdominal muscles.
- Adhesions: Bands of scar tissue from previous surgeries.
- Foreign Bodies: Ingested objects that block the intestine.
- Ischemic Colitis: Reduced blood flow leading to tissue damage and blockage.
- Paralytic Ileus: Muscle paralysis preventing movement of intestinal contents.
- Colon Polyps: Growths that can become large enough to block the intestine.
- Radiation Therapy: Can cause scarring and narrowing of the intestine.
- Bezoars: Masses of indigestible material blocking the colon.
- Endometriosis: Tissue similar to the lining of the uterus growing in the colon.
- Colonic Diverticula: Pouches that can become inflamed or infected.
- Appendicitis: Swelling of the appendix can sometimes lead to obstruction.
- Pelvic Tumors: Growths pressing on the colon.
- Neurological Disorders: Affecting the nerves that control intestinal movement.
Recognizing these causes can aid in prevention and early detection of obstructions.
Symptoms of Large Intestine Obstruction
Symptoms vary depending on the severity and location of the blockage. Here are 20 common symptoms:
- Abdominal Pain: Cramping or sharp pain in the abdomen.
- Bloating: Feeling of fullness or swelling in the abdomen.
- Constipation: Inability to pass stool or gas.
- Nausea: Feeling sick to the stomach.
- Vomiting: Expelling stomach contents.
- Loss of Appetite: Reduced desire to eat.
- Inability to Pass Gas: Gas buildup due to blockage.
- Swelling of the Abdomen: Visible enlargement.
- Diarrhea: Sometimes watery stool occurs above the blockage.

Surgical Treatments
When non-pharmacological and medication treatments are insufficient, surgery may be necessary to remove the blockage or repair the intestine. Here are 10 common surgeries:
- Colectomy:
- Removal of a part or all of the colon.
- Can be partial or total depending on the obstruction’s location.
- Hartmann’s Procedure:

- The colon is reconnected in a later surgery.
- Colostomy:
- Diverts stool through an opening in the abdomen.
- Useful for obstructions not immediately repairable.
- Sigmoid Resection:
- Removes the sigmoid colon section.
- Often used for volvulus or cancer.
- Adhesiolysis:
- Removes scar tissue causing the blockage.
- Common after previous abdominal surgeries.
- Vagotomy:
- Cuts the vagus nerve to reduce stomach acid.
- Rarely used solely for obstruction.
- Percutaneous Endoscopic Colostomy (PEC):
- Creates a colostomy using an endoscopic approach.
- Minimally invasive alternative.
- Laparotomy:
- Open surgery to access the abdominal organs.
- Allows direct removal of the obstruction.
- Laparoscopic Surgery:
- Minimally invasive surgery using small incisions and a camera.
- Shorter recovery time compared to open surgery.
- Resection and Anastomosis:
- Removes the blocked section and reconnects the healthy ends.
- Restores normal bowel continuity.
Surgical decisions depend on the obstruction’s cause, location, severity, and the patient’s overall health. Early surgical intervention can prevent complications and improve outcomes.
