The Hidden Tail: Rapunzel Syndrome Complicated by Gangrenous Small Bowel Obstruction — A Case Report
This case report describes a 19-year-old female with Rapunzel syndrome who developed gangrenous small bowel obstruction due to a trichobezoar, highlighting the critical need for early surgical intervention and long-term psychiatric management in young females with trichophagia presenting with intestinal obstruction.

Imagine your digestive system as a long, winding highway designed to move food from your mouth to your exit. Usually, this highway is smooth and clear. But in this case report, a 19-year-old woman's highway got blocked by something very unusual: a massive, tangled ball of her own hair.
Here is the story of what happened, explained simply:
The "Rapunzel" Problem
You might know the fairy tale of Rapunzel, the princess with incredibly long hair. In the medical world, "Rapunzel Syndrome" is a rare condition named after her. It happens when someone with a psychological habit of pulling out their own hair (trichotillomania) and eating it (trichophagia) swallows so much hair that it gets stuck in their stomach.
Think of the stomach as a washing machine. Most food gets broken down and washed away. But hair is like a super-strong, waterproof rope; the stomach acid can't dissolve it, and the stomach's churning motion can't break it apart. Instead, the hair gets matted together with mucus and food, forming a giant, solid knot called a trichobezoar.
In this specific case, the knot didn't just stay in the stomach. It grew so long that it reached out of the stomach and snaked all the way down into the small intestine, looking like Rapunzel's long hair trailing behind her.
The Emergency
The young woman arrived at the hospital in pain. For 10 days, her belly had been hurting, and for the last few days, she couldn't keep food down or pass any gas or stool. She was also very pale and weak because the hair ball was blocking her body from absorbing nutrients.
When the doctors examined her, they found her belly was swollen and tender. They knew something was blocking her intestines. Because she was in such bad shape (her heart was racing, and she had signs of infection), they didn't wait for more tests. They took her straight to surgery.
The Surgery: Finding the "Tail"
Inside, the surgeons found exactly what they feared. There was a hair mass about 26 centimeters long (roughly the length of a ruler) and 3 centimeters wide. It was jammed tight in her small intestine, acting like a cork in a bottle.
Because the blockage had been there for so long, the pressure had cut off the blood supply to a section of her intestine. This caused that part of the bowel to turn gangrenous (essentially, the tissue started dying). It was like a garden hose that had been kinked so tightly for too long that the water stopped flowing and the hose itself began to rot.
The surgeons had to cut open the intestine, remove the giant hair ball, and remove the dead section of the bowel to save her life.
The Aftermath and the Real Cause
After the surgery, the woman recovered quickly. But the doctors knew the physical blockage was only half the problem. When they spoke with her and her mother, they discovered the root cause: she had been pulling out and eating her hair for a long time, a habit she had kept secret.
She also had patches of missing hair on her scalp, which is a common sign of this behavior. The doctors explained that while the surgery fixed the immediate danger, the real work was just beginning. She needed help from a psychiatrist to stop the habit of eating hair, or else the "hair knot" would just grow back.
The Takeaway
This paper tells us that if a young woman comes to the hospital with a blocked intestine, unexplained anemia (low blood), and a history of hair-pulling, doctors should think of Rapunzel Syndrome.
- The Lesson: Hair doesn't digest. If you eat it, it builds up like a snowball rolling down a hill, getting bigger and more dangerous.
- The Solution: In severe cases like this one, where the intestine is dying, surgery is the only way to save the patient.
- The Future: To prevent this from happening again, the patient must get psychiatric help to stop the behavior that caused the blockage in the first place.
The patient herself said after the surgery that she didn't realize her habit could cause such a serious problem, but she was grateful for the help and understood she needed to keep seeing her counselor.
