Rapunzel syndrome is an extremely rare intestinal condition in humans resulting from ingesting hair (

trichobezoar. Since 1968, there have been fewer than 40 documented cases in the literature.[4]
This syndrome occurs when the trichobezoar (hairball) reaches past the small intestine, and sometimes even into the colon producing a long tail-like extension of hair (NCBI, 2016).

Signs and symptoms

The use of the term Rapunzel syndrome first appeared in the literature in 1968.[5]

Characteristics of the syndrome include:[citation needed]

  • The body of a
    colon
  • Small or large bowel obstruction
  • Occurring in psychiatric patients
  • Trichotillomania
  • Abdominal pain
  • Nausea & vomiting
  • Gut perforation
  • Vitamin B12 deficiency
  • Acute pancreatic necrosis

Cause

Rapunzel syndrome is caused by the ingestion of hair. Rapunzel syndrome is characterized by a compulsive disorder of pulling one's own hair and ingesting it. There are several psychiatric disorders that are associated with Rapunzel syndrome, such as trichotillomania, trichophagia, and pica. Trichotillomania is the compulsion to pull out one's own hair; if an individual consumes it after ripping it out as well, it is known as trichophagia. Pica comes from the Latin word for "magpie" and involves the craving of non-food items such as cloth, wool, hair, or even small metallic objects.[citation needed]

Diagnosis

Trichobezoar can be preoperatively diagnosed. However, the diagnosis of the Rapunzel syndrome has to consider several aspects such as the patient's history with disorders like trichophagia and trichotillomania.[6][7] This syndrome does not appear in the DSM V, and will therefore not be given as such, but will have been diagnosed as severe trichotillomania.[8] The syndrome itself is used to describe the manifestation of a trichobezoar which has extended far into the small intestine. It describes the trichobezoar, not the mental health disorder which precipitated it.[7]

The diagnosis of the syndrome is also done by endoscopy. A CT scan is recommended to determine the size and the extension of the trichobezoar.[5] Upper GI endoscopy is known as the gold standard for the diagnosis of a trichobezoar, however the endoscopy alone might not necessarily detect the co-existing Rapunzel syndrome.

Treatment

Because the

impulse control disorders, especially trichotillomania.[9] Long-term follow up as well as psychiatric consultation is also recommended to prevent the event from repeating.[citation needed

Outcomes

The expected outlook after surgical intervention is very promising. The success rate of removal of the mass is above 90% and the complication rate is only near 10%. Recurrence is highly uncommon but can occur if the patient does not follow up on psychological treatment or counseling.[citation needed]

Epidemiology

Rapunzel syndrome is extremely rare, with less than 64 cases reported since 1968. It is mainly seen in emotionally or mentally disturbed young or adolescent females. The first known case dates back to a 16-year-old boy in 1779; this was eventually published by Vaughan et al. in 1968. Of the cases reported, the typical age range affected from this syndrome is between 4 and 19 years of age. There is no specific region that is subject to developing this condition, however of the cases reported all of the women came from countries where women traditionally had long hair. Women are more subject to this disorder because women often have longer hair than men. There is only one reported male case of Rapunzel syndrome, but he was eating his sister's hair and not his own.[citation needed]

Research

Although this condition is extremely rare, researchers have mentioned that it is absolutely critical that prevention methods are taken after surgery. The most common reason for recurrence in patients is lack of follow-up care and incompletion of psychological treatment. Researchers have concluded that 92.5% of all cases reported were treated by laparotomy with a 99% success rate (NCBI,2016). There have been few reports of successful treatment through laparoscopic surgery, however this has only been reported to be done in pediatric patients.[citation needed]
