Have you recently undergone surgery, particularly an abdominal procedure? Or are you suffering from persistent, unexplained abdominal pain or a recurring pulling sensation in your abdomen? Sometimes, the cause might be something you wouldn't typically suspect: internal organs sticking together. In medical terms, we call this condition adhesions. While the name may sound unfamiliar, it is a common post-surgical occurrence. Let’s break down everything you need to know about adhesions in simple, clear terms.
What exactly are Adhesions?
Simply put, adhesions are internal bands of scar tissue that form inside your body. Think of what happens when your skin is cut; as the wound heals, a scar forms. Similarly, inside your body, adhesions are bands of scar tissue that bridge the gap between two organs or tissues that are not normally connected. These can manifest as thin, film-like sheets resembling cellophane or as thick, cord-like bands.
The primary cause of adhesions is your body’s natural healing process. When your tissues are damaged—whether by surgery, infection, injury (trauma), or radiation therapy—your body initiates a repair response. During this healing, if a damaged organ comes into contact with another surface, your body's healing cells may struggle to distinguish between them. As a result, they create scar tissue that binds the two surfaces together, forming an adhesion.
Where do Adhesions most commonly form?
While adhesions can form almost anywhere in the body, there are specific, common locations:
| Location | Impact and Description |
|---|---|
| Abdominal Adhesions | This is the most common type. More than 90% of people who undergo abdominal or pelvic surgery may develop these. They can cause intestines to stick, fold, or twist. The most serious risk is a bowel obstruction, where the movement of food through the intestines is partially or completely blocked. |
| Pelvic Adhesions | These can form between a woman’s uterus, ovaries, and fallopian tubes, often due to conditions like Pelvic Inflammatory Disease (PID) or Endometriosis. Adhesions in the fallopian tubes can increase the risk of infertility and ectopic pregnancy, and are also a common cause of chronic pelvic pain. |
| Pleural Adhesions | Following pneumonia, tuberculosis, or chest surgery, scar tissue may form between the membranes covering the lungs, which can cause pain during deep breathing. |
| Heart Adhesions | If adhesions form between the membranes surrounding the heart (pericardial sac), they can impede cardiac function. Infections like rheumatic fever can also cause adhesions on heart valves, reducing the heart's overall efficiency. |
What are the symptoms of Adhesions?
Crucially, most adhesions cause no symptoms at all. They may remain inside your body for years without you ever knowing they exist. Symptoms typically only arise if the adhesions begin to interfere with the normal function of an organ.
Possible symptoms include:
- If you have intestinal adhesions, you might feel a pulling or aching sensation in your abdomen during exercise or movement.
- In women, adhesions near the pelvic region can cause pain during intercourse.
- Adhesions near the lungs may cause sharp pain or difficulty when taking a deep breath.
- Adhesions involving the heart may result in chest pain.
Bowel Obstruction – This is an Emergency!
The most severe complication of abdominal adhesions is a bowel obstruction. This is a medical emergency where the intestine is blocked, preventing the passage of food. Recognizing these signs is vital:
- Sudden, severe, cramping abdominal pain that lasts for several minutes, often worsening after eating.
- Vomiting accompanying the pain; you may feel temporary relief after vomiting.
- Abdominal bloating and swelling.
- Loud, high-pitched stomach noises.
- If symptoms progress, the pain may become constant, normal bowel sounds may cease, and you may experience a complete inability to pass gas or stool, often accompanied by a fever.
If you experience these symptoms, especially if you have had prior abdominal surgery, do not ignore them. This could be a bowel obstruction. Seek medical attention immediately at your nearest Emergency Department (ER).
How are Adhesions diagnosed?
Adhesions are notoriously difficult to see on standard imaging tests like X-rays or CT scans. While these tests can reveal a bowel obstruction, they cannot definitively pinpoint an adhesion as the cause.
The only way to definitively diagnose an adhesion is through a procedure such as a Laparoscopy. During this procedure, a surgeon makes a small incision and inserts a camera to examine the abdominal cavity. If adhesions are found, the surgeon can often remove them during the same procedure.
What are the treatments?
If adhesions are asymptomatic, no treatment is necessary. However, if they cause significant symptoms, treatment is required. The primary method is surgical removal, known as Adhesiolysis.
There are two main surgical approaches:
| Surgical Method | Description |
|---|---|
| Laparoscopy | Known as "keyhole surgery," this method involves a few small incisions to insert a camera and instruments to precisely cut and remove the adhesions. |
| Laparotomy | This is "open surgery." A larger incision is made in the abdomen, allowing the surgeon to visualize the area directly to remove the adhesions. |
A paradox of this treatment is that the surgery itself may cause new adhesions to form, as the body’s healing response is triggered again by the surgical intervention.
Can Adhesions be prevented?
While they cannot always be fully prevented, surgeons take several precautions during operations to minimize the risk:
- Minimizing the time taken for the surgery.
- Handling tissues with extreme gentleness and care.
- Keeping tissues moist throughout the procedure.
- Using specialized starch-free and latex-free gloves.
- In some cases, placing specialized anti-adhesion barriers (film-like sheets) between organs.
If you are preparing for surgery, feel free to discuss these preventative measures with your surgeon.
Key Takeaways
- Adhesions are internal bands of scar tissue that form, most commonly following surgery.
- Most adhesions are harmless, but some can lead to pain, infertility, or severe complications like bowel obstructions.
- If you have a history of surgery and experience severe abdominal pain, vomiting, and bloating, treat it as a medical emergency and seek care immediately.
- Diagnosis is typically confirmed during surgical visualization.
- Even after surgical removal, there is a risk of adhesions returning.
- Always consult your doctor if you experience any unusual symptoms after a surgical procedure.
