A trichobezoar is a rare condition, mostly seen in teenage girls with abnormal psychiatric behavior of eating hairs and nails (trichophagia). Trichobezoar may rarely present with nonspecific abdominal symptoms without obvious trichotillomania and trichophagia. Trichobezoar can be complicated with potentially serious conditions such as gastric outlet obstruction, gastric bleeding, intussusceptions, and perforation peritonitis. Conventional laparotomy is method of choice for the removal of trichobezoar. We describe a rare case of giant trichobezoar treated by laparoscopic-assisted gastrostomy and removal of bezoar. We also reviewed the literature on the current status of endoscopic treatment of trichobezoar.

| Introduction|| |
A trichobezoar is a rare condition consisting of a hair ball in the proximal gastrointestinal tract. It is mostly seen in teenage girls with abnormal psychiatric behavior of eating hairs and nails (trichophagia). Trichotillomania, a psychiatric disorder characterized by the compulsory and persistent pulling out of one's hair, leads to noticeable hair loss. The trichobezoar is mostly confined within the gastric lumen. Rapunzel syndrome is a rare form of trichobezoar with a long tail which may extend up to the jejunum or beyond. The prevalence rate varies from 0.06% to 4%. We describe a rare case of giant trichobezoar treated by laparoscopic-assisted removal of bezoar. We also reviewed the literature on the current status of endoscopic treatment of trichobezoar.
| Case Report|| |
A 13-year-old girl presented with pain abdomen, anorexia, infrequent vomiting, weight loss, and constipation for 2 years. There was no history of abdominal distension or fever. History of prior abdominal surgery and other chronic illness was absent. Multiple soft nontender nodules were palpable in epigastrium and left hypogastrium. Abdominal computed tomography (CT)-scan showed an inhomogeneous mass with scattered calcification in stomach extending up to duodenal lumen. Endoscopy showed a large hair ball (trichobezoar) almost completely occupied the stomach [Figure 1]. Hair ball extending from gastroesophageal junction and entered into duodenum [Figure 1]a, [Figure 1]b and [Figure 1]c. Distal extent of hair ball could not be visualized because endoscope was not negotiable through pylorus due to blocked pyloric opening [Figure 1]c. Diagnosis of trichobezoar was confirmed. The patient denied eating hairs, though her hair density was sparse. In view of large size of bezoar, endoscopic removal was not tried. Laparoscopic-assisted gastrostomy and removal of trichobezoar (size 26 cm × 8 cm) [Figure 2] were successfully performed. The patient was discharged in a healthy condition. The patient was referred to psychiatrist for counseling.

| Discussion|| |
The patient with trichobezoar remains asymptomatic for many years. Large-sized trichobezoar usually presents with symptoms of gastrointestinal obstruction. The most common presenting clinical symptoms and signs are abdominal pain, vomiting, constipation, and weight loss. Bezoar can be complicated with gastric ulceration, gastric bleeding, intussusceptions, perforation peritonitis, obstructive jaundice, acute pancreatitis, gastric emphysema, protein-losing enteropathy, iron deficiency, and megaloblastic anemia.,
History of associated psychiatric disorders and patchy alopecia provide useful clues for the diagnosis of trichobezoar. However, the patient may conceal history of pulling out (trichotillomania) and eating their own hair (trichophagia). History of trichophagia is absent in nearly half of the patients of trichobezoar. History of trichophagia was concealed by our patient. The investigation of choice in the diagnosis of trichobezoar is endoscopy. Endoscopic diagnosis of trichobezoar is sometimes very surprising, especially in the absence of trichotillomania and trichophagia. Abdominal ultrasound and CT scan may show inhomogeneous mass or filling defect in gastric lumen with or without calcification.
The treatment may include medical, conventional laparotomy, laparoscopy, and endoscopic methods. Psychiatric consultation is essential to prevent relapses. Medical treatments such as intragastric installation of enzyme, sodium bicarbonate, and coca cola have been tried without any consistent success. Conventional laparotomy is method of choice for the removal of trichobezoar., Surgical removal is performed by gastrostomy or enterotomy. Laparoscopy techniques have been described for removal of small- to moderate-sized bezoars., Laparoscopic removal of large bezoars is difficult. Other problems of laparoscopy include longer operation time, the risk of migration of bezoars toward ileum, and the risk of spilling contaminated hair fragments into the abdominal cavity.,
Recently, endoscopic removal of trichobezoars of smaller size has been described in a few case reports.,,,,, Endoscopic removal is based on the use of intragastric chemical substances (sodium bicarbonate) to dissolve the material, mechanical fragmentation, and removal of bezoars with repeated endoscopy. The details of the endoscopic techniques are summarized in [Table 1]. Endoscopic technique has very low success rate (5%). The following factors are responsible for the poor result of endoscopic removal of trichobezoars: (a) endoscopic removal is a tedious procedure, (b) carries risk of complications such as pressure ulceration, esophagitis, and even esophageal perforation due to repeated introduction of the endoscope, and (c) hair ball can migrate distally and obstruct intestine.
In conclusion, trichobezoar is a rare and potentially serious disease. Trichobezoar may present with nonspecific abdominal symptoms without obvious trichotillomania and trichophagia. A young female presenting with unexplained abdominal symptoms should be evaluated for trichobezoar.
