RESUMO
BACKGROUND AND STUDY AIMS: Invagination, which can occur in any part of the intestine, usually affects children and is the second most common cause of intestinal obstruction after pyloric stenosis. The cause of these intussusceptions in children is usually unknown and they typically occur within the ileocolic region. Management of pediatric patients with the condition often consists of surgical intervention. However, this retrospective study from the University Hospital of the University of São Paulo, Brazil, reports a series of cases of intussusception in children in whom a colonoscopy was used to reverse the intussusception. PATIENTS AND METHODS: From April 2010 to January 2015, 30 pediatric patients underwent a colonoscopy as an noninvasive method for treatment of children's intestinal intussusception. RESULTS: Overall, treatment with colonoscopy was successful in reversing invagination in 66.7â% of the patients. However, 33.3â% of patients required surgery to resolve the intussusception. CONCLUSION: Noninvasive colonoscopy is a potential treatment for intussusception in children.
RESUMO
The gastrointestinal (GI) tract has been increasingly affected by tuberculosis, especially in immunocompromised patients. Although strict rectal involvement is rare, the GI site mostly affected is the ileocecal region. Thus, tuberculosis should always be considered in the differential diagnosis of perianal and rectal lesions, and more so in patients infected by the HIV virus. The authors report the case of a 32-year-old man presenting a long-term history of fever, night sweats, weight loss, bloody diarrhea, fecal incontinence, tenesmus, and rectal pain. HIV serology was positive. The patient underwent anoscopy and biopsy, which disclosed the diagnosis of rectal tuberculosis. Thus the patient was referred to an outpatient clinic to follow the standard treatment.
RESUMO
Objetivou-se desenvolver com metodologia experimental, um modelo cirúrgico preocupado com a complexidade da técnica, aplicabilidade e tempo de duraçäao, utilizando retalho do músculo esternocefálico para reconstruçäo parcial do esôfago cervical, estudando ainda a integraçäo do retalho através da cicatrizaçäo e circulaçäo. Utilizamos 30 cäes machos com peso médio de 14,37Kg. Após a observaçäo pós-operatória, os aniamis foram divididos aleatoriamente em dois grupos de quinze cäes para avaliaçäo da circulaçäo e cicatrizaçäo da reparaçäo esofágica. A grande maioria dos cäes (80 por cento) ganhou peso, näo apresentando dificuldade de deglutiçäo, episódios de regurgitaçäo, e endoscopicamente nenhum dos animais demonstrou presença de fístulas e estenoses. A injeçäo com neoprene látex permitiu verificar pequenos ramos arteriais provenientes do retalho muscular e que supriam a regiäo da reconstruçäo. Os achados histológicos demonstraram quadro de atividade inflamatória crônica, em fase remissiva, na maioria dos cäes analisados, caracterizando portanto integraçäo do retalho com o órgäo.
