Resumo

Background: Bezoars are accumulations of foreign material and indigestible organic substances in the gastrointestinal tract. There are different classifications for bezoars based on its primary composition. The trichobezoars are concretions composed of hair or hair-like fibers and are often associated with trichophagia in humans. The obstruction by a trichobezoar occurring in the stomach, with its tail extending to or beyond the ileocecal valve or jejunum is rare in humans. This condition is called Rapunzel Syndrome. Obstruction by trichobezoar has been reported few times in cats and dogs. This paper aims to describe an uncommon clinical presentation of a young dog with partial obstruction of the small intestine by a trichobezoar. Case: A 2-year-old, 5.5 kg, intact male poodle was referred due to kyphosis and a history of pain in the thoracolumbar region for approximately 10 months. Physical examination revealed that the dog walked without any difficulty or ataxia, but had pain on palpation of the lumbar vertebral column. Thoracolumbar spine radiographies failed to show any sign of disease. Conservative therapy for intervertebral disk disease did not shown any improvement. In addition, the dog showed signs of pain on abdominal palpation and 18-month history of hyporexia, apathy and dark colored diarrhea. Abdominal ultrasonography detected a 5-cm intraluminal intestinal structure at the ileo-jejunal junction, forming an acoustic shadow, with focal thickening of the intestinal wall. Exploratory celiotomy followed by jejunal enterotomy revealed a trichobezoar consisting of undigested hair and textile fibers partially obstructing that segment. The intestinal wall in that region formed a sacculation, so a 5 cm jejunal resection with end-to-end anastomosis was performed. Histopathology of this segment did not show any neoplastic formation. After 20 days of surgical procedure, no clinical […](AU)
