Intussusception, which is the prolapse of one section of intestine into another, is a common cause of small-bowel obstruction in pediatric patients. Bezoars are concretions of ingested foreign material. Trichobezoars, which are bezoars made of hair, occur in the context of trichotillomania, the compulsive pulling of hair, and trichophagia, the eating of hair. If gastric trichobezoars grow to sufficient size, an intestinal extension can serve as a lead point for intussusception to occur. Rarely, hair passes completely through the stomach and forms a trichobezoar within the small bowel. This obstruction can also create lead points and cause intussusception. This is one of the few reported cases of intussusception due to a primary intestinal bezoar.
We present the case of an 8-year-old boy with an unknown history of trichophagia and a preliminary diagnosis of appendicitis. Upon imaging, a bowel obstruction related to a small-bowel intussusception was discovered to be the probable cause. A diagnostic laparoscopy revealed an ileo-ileal intussusception caused by an ileal bezoar. Conversion to exploratory laparotomy assisted in removing the causative bezoar. The patient recovered without postoperative complications.
We report a case of an isolated intestinal trichobezoar causing intussusception in a boy. While intussusception secondary to a trichobezoar most commonly occurs due to ‘Rapunzel syndrome,’ this case shows that it is possible for an intestinal trichobezoar to form without the presence of ‘Rapunzel syndrome.’ This unique cause of intussusception presented as a small-bowel obstruction, requiring evacuation of the bezoar.
