A Case of Rapunzel Syndrome

Trichobezoar is a concretion of chewing and swallowing hair or any other indigestible materials that accumulate in the gastrointestinal tract. Rapunzel syndrome refers to a rare condition when a gastric trichobezoar extends into the small bowel. We describe the case of a 16-year-old female who presented with chronic abdominal pain, loss of appetite and weight loss. Based on her past medical history, trichophagia has already been revealed at preschool age. Imaging tests indicated a large fi lling of the stomach. Upper gastrointestinal endoscopy showed a large trichobezoar in the stomach with prolonga on through the pylorus. The patient underwent exploratory laparotomy and the trichobezoar was removed. Upper gastrointestinal endoscopy is the preferred modality for diagnosis and in most cases the treatment is surgical.

Introduction
Bezoars are intraluminal accumulations of indigestible material. They have been classifi ed into phytobezoars (comprised of vegetable and fruit residue), lactobezoars (comprised of milk residue), pharmacobezoars (comprised of pills and capsules) and trichobezoars (an accumula on of hair), according to their dominant composition [1]. Trichobezoars are common in patients with mental retardation, psychiatric disorders or personality disorders such as trichophagia and trichotillomania.
Rapunzel syndrome is a rare condition when a gastric trichobezoar extends into the small bowel increasing the risk of complications such as obstruction, perforation and peritonis [2]. The syndrome is named a er the heroine of a German fairy tale written by the Grimm Brothers and fi rst published in 1812. The fairy tale is about a young princess with a long golden hair imprisoned by a witch in a tall tower with neither stairs nor a door [1]. One day, a prince rode through the forest and heard Rapunzel singing from the tower. After a while, they fell in love with each other, the princess lowered her long hair to the ground from her window, so the prince could climb up and rescue her. According to these symptoms and examination results we expected to fi nd a large bezoar during the gastroscopy but we could not expect that it extended through the pylorus. Because of the large size it was certain that surgical intervention was needed. So the actual outcome of the treating plan was similar to our expected outcome. Since then the patient has been under gastroenterological control.

Discussion
We have described a rare cause of chronic abdominal pain among children by introducing the case of a 16-year-old female who had a history of trichophagia. The diagnosis was based on the patient's medical history, physical examination, imaging tests and upper gastrointestinal endoscopy. The bezoar was removed by exploratory laparotomy. Rapunzel syndrome is a rare condition in paediatric population. During the differential diagnosis of chronic abdominal pain, we have to think about Rapunzel syndrome if there is a history of trichotillomania or trichophagia.
Trichobezoar is a concretion of chewing and swallowing hair that accumulates in the stomach and fails to pass through the intestines. If it extends into the small intestine, it is referred to as Rapunzel syndrome. The syndrome was fi rst described by Vaughan, et al. in 1968 [3,4].
It is a very rare entity in paediatric population, most commonly affecting women under the age of 30, mainly associated with psychiatric conditions [5].
Symptoms could include abdominal pain, loss of appetite, nausea/vomiting, and weight loss. Patients can be asymptomatic until the bezoar reaches the point of obstruction. The following complications may occur: gastric ulceration, acute pancreatitis, gastric perforation, obstructive jaundice, complete intestinal obstruction, severe peritonitis [6,7].
Small bezoars can be extracted via endoscopy using various disintegrating techniques, but in most cases a surgical management is needed because of the large size [8,9]. Rou tine endoscopy, ultrasonography can be used for detection of recurrence.
