Hello everyone! Today, I want to share a truly astonishing and unfortunate case. A previously healthy 9-year-old girl was rushed to the emergency room with severe abdominal pain and vomiting. It turned out the cause was a rather unfamiliar condition called 'Rapunzel Syndrome.' Like the fairy tale princess Rapunzel, a massive hairball had formed inside the child's stomach. This led to mechanical pancreatitis and biliary duct dilation, conditions extremely rare in children. It's hard to even imagine how much pain she must have endured. Today, through this shocking case, we will delve into what 'Rapunzel Syndrome' is, why it causes such severe complications, and how it should be managed.

Rapunzel Syndrome: A Fairy Tale Becoming Reality?

The name 'Rapunzel Syndrome' itself is intriguing, isn't it? The condition is derived from the fairy tale 'Rapunzel,' where the princess let down her long hair from a tower window. Medically, a mass of hair accumulated in the stomach is called a 'trichobezoar.' When this mass grows large enough to pass through the pylorus, the narrow opening of the stomach, and extends tens of centimeters into the small intestine, it is termed 'Rapunzel Syndrome.' First described in the medical literature in 1968, it is exceptionally rare in children. A case like this 9-year-old girl's is one of only about 100 reported worldwide, highlighting how truly shocking this event is.

Hair Forming a Giant Mass in the Stomach? The Cause is 'Pica'

So, how did the child ingest so much hair? The 9-year-old protagonist in this case was found to have a habit of secretly swallowing her hair, leading to the formation of a large 'trichobezoar' in her stomach. The persistent ingestion of non-nutritive substances like hair, soil, paper, or soap for over a month is known as 'pica.' Pica is a type of eating disorder. Why didn't the parents notice the child's hair-swallowing habit? Often, pica is accompanied by 'trichotillomania' (hair-pulling), which can leave noticeable circular hair loss on the scalp. However, in this young patient's case, it's presumed she plucked only a few strands of hair from various parts of her scalp or habitually picked up and swallowed loose hairs from the floor, clothes, or toys. This made it difficult to detect any outward signs. Since hair is not digestible by human enzymes, ingested hair accumulates in the body. It can take months to years for a mass to fill the stomach, and initially, there may be no symptoms. However, as the mass moves into the small intestine and presses on surrounding organs, it eventually causes severe abdominal pain.

Life-Threatening Complications Caused by the Hair Mass: Mechanical Pancreatitis and Biliary Dilation

Upon arrival at the emergency room, this patient presented with extremely high serum lipase levels (1035 IU/L), consistent with acute pancreatitis. While abdominal ultrasound showed no gallstones, it did reveal dilated intrahepatic and extrahepatic bile ducts, a condition known as 'biliary duct dilation.' This occurred because the hair mass had passed through the pylorus into the small intestine, extending about 40 cm. It caused 'intussusception' (telescoping of the intestine) and exerted significant pressure on the duodenum and other structures. This pressure obstructed the pancreatic duct, preventing the proper flow of pancreatic enzymes. Consequently, the enzymes began to digest the pancreas itself, leading to mechanical pancreatitis and biliary dilation. Pancreatitis is a dangerous condition where digestive enzymes within the pancreas cause inflammation by digesting the pancreatic tissue. In this case, the development of 'mechanical pancreatitis' due to a physical obstruction makes it even rarer.

Complete Recovery After Surgery, but Caution Regarding Recurrence is Necessary

Fortunately, the research team successfully removed the massive hairball from the patient's stomach through an incision in the stomach and small intestine. After the surgery, the child's abdominal pain subsided, her serum lipase levels returned to normal, and she was discharged in stable condition. However, it's crucial to understand that while surgical removal effectively addresses the acute symptoms, it does not resolve the underlying causes of 'pica' or 'trichotillomania.' Without addressing these behavioral issues, there is a high risk of recurrence. These behavioral disorders are often closely linked to psychological factors or psychiatric conditions. Therefore, continuous psychological therapy and behavioral modification are essential after surgery to address the root causes. In essence, **comprehensive, multidisciplinary treatment** is absolutely necessary.

This case demonstrates how seemingly minor habits in children can lead to severe consequences that we might easily overlook. If a child exhibits behaviors like hair-pulling or swallowing, complains of digestive issues without a clear cause, or if a mass is palpable in the abdomen, it's important to consider rare conditions like Rapunzel Syndrome and consult a specialist immediately. With early detection and appropriate treatment, children can regain their healthy lives.
