RESUMO

We documented a 23 kg bezoar that filled >60% of the rumen of an adult oryx (Oryx gazella gazella) harvested in New Mexico, US. The nidus of the bezoar was comprised of nylon cords and parachute cloth, constituents of parachutes. Although slightly thin, the oryx was otherwise healthy at harvest.

RESUMO

Trichobezoars are an unusual pathology that appears generally in young adolescents associated with psychiatric disorders. The clinical presentation is very varied. The diagnosis is suspected by the clinical records of teen agers with trichophagia and trichotillomania and the digestive disorders are confirmed by the results of the endoscopy, the same as with images toward the therapeutic management. Undowbtly the treatment is surgical, and continuation with the psychiatric treatment is essential to avoid a recidival of the disease. Bezoar is a concretion formed in the alimentary tract, and according to the substances forming the ball, we find trichobezoar (foodball). The Rapunzel syndrome is an unusual complication of individual bezoar. When the trichobezoar located in the stomach extends through the pylorus into the small intestine and the right colon, is known as Rapunzel syndrome, that is an extremely rare gastric condition in humans. It is a rare form of trichobezoar, occurring in psychiatric patients with the trichobezoar (hairball) located in the stomach. The syndrome is named after the long haired girl Rapunzel in the fairy tale of the brothers Grimm. Most bezoars in teen agers are trichobezoars from swallowed hair. A 28-year-old patient is presented, with abdominal pain and vomiting, on the general physical examination the patient revealed a severe weight loss. Later on, through a gastrostomy, appeared the trichobezoar, being removed with good postsurgical resullts

RESUMO

Tricobezoares são corpos estranhos gástricos compostos por cabelos dos próprios pacientes. São mais comuns em crianças, principalmente do sexo feminino. Cursam freqüentemente com sintomas gastrintestinais como dor abdominal, náuseas, vômitos, anorexia, perda de peso e plenitude pós-prandial. Massa epigástrica, alopécia e antecedentes de tricofagia podem estarpresentes. O tratamento de eleição é o cirúrgico, acompanhado de tratamento psiquiátrico. Este trabalho tem como objetivo relatar três casos de pacientes com tricobezoar gástrico e realizar uma revisão da literatura. Todos os casos deste estudo eram de crianças dosexo feminino. Dois pacientes cursaram com quadro de suboclusão intestinal, apresentando dor abdominal evômitos. Em um caso havia dor abdominal não acompanhada por vômitos. Todos apresentaram antecedentes de tricofagia, bem como massa epigástrica palpável. Um com áreas de alopécia. O principal examede imagem empregado foi a seriografiaesofagogastroduodenal. Todos foram submetidos a tratamento cirúrgico mediante gastrotomia e encaminhados para serviço de psicologia, com boaevolução clínica.

Trichobezoars are concretions of ingested hair that most often lodge in the stomach. They are commonlyseen in young girls with psychiatric disorders. Upper gastrointestinal symptoms usually are progressive andmay include abdominal pain, nausea and vomiting, early satiety, weight loss, bloating, diarrhea or constipation. Ahistory of tricophagia is common. Physical examination may include the presence of nontender palpable massand bald spot. Gastric trichobezoars require removal through an anterior gastrotomy. Postoperatively, psychiatric intervention is often appropriate. The purpose of this study was to describe three cases of patients with gastric trichobezoar and make a review of literature. All patients studied were yo ung girls. Two patients presented abdominal pain and vomiting. In one case there was abdominal pain without vomiting. All cases presented tricophagia and palpable mass. One had bald spot. Barium contrast study was the most beneficial in the diagnosis. In our cases, bezoars were removed easily via single gastrotomy. Postoperatively they were evaluated by psychology. The remainder of their hospital course wasunremarkable.

RESUMO

BACKGROUND: There is little information available concerning trichobezoars in the non-human primate literature. METHODS: We evaluated 118 cases of trichobezoar in baboons over a 29-year period at the Southwest National Primate Research Center. RESULTS: The anatomic locations affected in decreasing order were the stomach, small intestine, cecum, esophagus and colon. The most common clinical history was weight loss. The most frequent associated pathology included gastrointestinal inflammation and ulceration, emaciation, peritonitis, intussusception, pneumonia, and aspiration. Trichobezoars were the cause of death in nine baboons and the reason for euthanasia in 12. Females were 2.14 times more likely than males to be affected. The greater the percentage of group housing time, the more likely the baboon is to develop trichobezoars. CONCLUSIONS: The baboon may present a useful model to evaluate the etiology, genetic predisposition, physiopathology, neurobiology, and treatment response of trichobezoars.

RESUMO

Los tricobezoar son recolecciones de material ingerido (pelos, fibras) que se acumulasn en estómago e intestino. Se originan de la tricotilomanía más tricofagia, cuando el tricobezoar se acumula en duodeno recibe el nombre de Sídrome de Rapunzel, más frecuente en el sexo femenino. Adolescente de 15 años, quien presentó dolor abdominal de aparición insidiosa acompañada de naúseas y vómitos incontables que se irradian a hipocondrio y fosa iliaca izquierda, su evolución fue torpida presentando signos de irritación peritoneal. Se realiza laparatomía exploradora hallándose tumor de contenido de pelo a nivel del Ángulo de Treitz, y cámara gástrica. Siendo egresada y referida al servicio de psiquiatría infanto-juvenil.

RESUMO

Context: Trichobezoars (TB) are bezoars formed by ingested hair. TB are more common among girls and young women. The findings include a hard, mobile and painless abdominal mass in the epigastrium, anorexia, nausea and vomiting, weight loss and reports of thichophagia. Image abdominal studies can confirm the diagnosis. The treatment is based on the complete TB remotion.Case report: M.O.M., 16 years old, female, single, student, born and living in São Paulo. She reported anorexia, abdominal discomfort, halitosis and mild colicky abdominal pain associated with a lump three years ago. On examination: huge, non-tender, mobile, painful, palpable mass in the upper abdomen (13cm) without inflammatory sign. Plain films of abdomen: diffuse radiopaque mass in upper abdomen without gastric bubble. Abdominal ultrasound and computadorized tomography show enlarged stomach filled by heterogeneous material. Endoscopy demonstrates the stomach completely filled with black hair. Once the diagnosis was made, surgical treatment was indicated.

RESUMO

The Rapunzel syndrome is a rare form of gastric trichobezoar crossing the pylorus and extending throughout the bowel. The case of a 22-year-old Peruvian woman is reported. This is the thirteenth patient with Rapunzel syndrome reported in the literature. The epidemiology, clinical manifestations, diagnosis and treatment are briefly reviewed.

RESUMO

Introducción: los tricobezoares son concreciones formadas de pelo que se ubican usualmente en estómago o intestino delgado produciendo oclusión de su luz. Esta rara enfermedad se observa en niños y mujeres jóvenes, su origen es un desorden obsesivo compulsivo. Los pacientes manifiestan dolor epigástrico, pérdida de peso, masa palpable móvil, y trastornos de comportamiento. Por lo general, niegan la ingesta de cabellos, en la primera entrevista. El diagnóstico se realiza mediante endoscopía, radiografía seriada esófago-gastro-duodenal y TAC. El tratamiento es quirúrgico, salvo en los bezoares pequeños que se pueden intentar resolver mediante endoscopía. Objetivos: análisis de 2 casos de pacientes con diagnóstico de tricobezoar. Lugar de aplicación: Servicio de Cirugía General del Hospital San Bernardo de la Ciudad de Salta. Material y método: dos casos de pacientes portadoras de tricobezoar tratadas en nuestro Hospital. Resultados: se presentan las dificultades diagnósticas y la resolución quirúrgica de ambos casos. Conclusiones: es una rara enfermedad que hay que sospecharla en pacientes jóvenes, por lo general de sexo femenino, con dolor abdominal, oclusión intestinal y trastornos del comportamiento. El diagnóstico se realiza mediante endoscopía y radiografía contrastada de abdomen. Su tratamiento, salvo en raras oportunidades, es quirúrgico
