Tricobezoar gástrico
Melo, Valdinaldo Arago de;Cardoso, Eduardo Góis;Melo, Gustavo Barreto de;
Revista do Colégio Brasileiro de Cirurgi?es , 2002, DOI: 10.1590/S0100-69912002000300010
Abstract: bezoar is a foreign body in the digestive tract originated from ingestion of varied substances, mainly vegetal hair or coats, staple fibers among others. we present a case of a 16-year-old female with trichotillomania history of approximately 5 months, diagnosed through clinical evidence of traumatic alopecia made by her dermatologist. though asymptomatic the presence of tricobezoar was suspected and confirmed through digestive seriography and high digestive endoscopy. the patient was operated on for gastrotomy and removal of bezoar, with good postoperative follow-up, except for surgical wound infection.

Acta Cirurgica Brasileira , 2003,
Abstract: OBJETIVO: Avaliar os efeitos do omeprazol e do pantoprazol sobre a regenera o hepática após hepatectomia parcial. MéTODOS: Cinqüenta e oito ratos Wistar machos foram divididos em 4 grupos: Grupo SHAM, Grupo HP, Grupo PANTO e Grupo OMEP. Eles foram submetidos a hepatectomia parcial de 67% (Grupos HP, PANTO e OMEP) ou laparotomia (Grupo SHAM). Os fígados foram removidos 32 e 56 horas após a opera o. Depois, os animais foram sacrificados. Em todos os grupos, as substancias (solu o salina, omeprazol e pantoprazol) foram aplicadas diariamente a partir do momento em que foram operados até o sacrifício. RESULTADOS: O índice de mitose no Grupo SHAM n o foi significativo. Trinta e duas horas após a hepatectomia, a contagem de mitoses foi de 1,2 ± 1,09 para o Grupo HP, 1,2 ± 1,6 para o Grupo OMEP e 2,6 ± 3,2 para o Grupo PANTO. Na análise após 56 horas, os valores foram 1,6 ± 0,89 para o HP, 2 ± 1,8 para o OMEP e 2,6 ± 0,54 para o PANTO. Esses resultados n o foram estatisticamente significativos. CONCLUS O: O omeprazol e o pantoprazol, agentes inibidores da bomba de prótons (H+, K+-ATPase), n o interferem na regenera o hepática 32 e 56 horas após hepatectomia parcial a 67% em ratos.

Revista do Hospital das Clínicas , 2003,
Abstract: Falciform ligament abscess is rare. We report a case of a 65-year-old man who presented with right upper quadrant abdominal pain, postprandial fullness, and fever. Computed tomography disclosed a cylindrical mass in the anterior abdomen that aroused suspicion of a hepatic abscess. At laparoscopic surgery, an abscess of the falciform ligament was found and drained. Two months later, the patient developed recurrence of the abscess secondary to acute calculous cholecystitis. Abscess drainage and cholecystectomy were performed. The presence of right uppper quadrant abdominal pain, epigastric tenderness, fever, leukocytosis, and a mass in the anterior abdomen should arouse suspicion of falciform ligament abscess. Its treatment consists of abscess drainage.

Abstract: OBJETIVO: Estudar os efeitos da anastomose porto-cava sobre a morfologia e bioquímica do fígado de c es. MéTODOS: Vinte animais foram divididos em 2 grupos: o Grupo I foi submetido à hepatectomia parcial de 28,7% e o Grupo II, à hepatectomia parcial associada à deriva o porto-cava. Os parametros analisados foram: peso corpóreo, colesterol e triglicérides plasmáticos, lipídios e glicogênio hepáticos e índice ponderal de regenera o hepática. Os dados foram analisados no pré-operatório e no 30° dia do pós-operatório. RESULTADOS: No Grupo I, apenas os lipídios hepáticos estavam significativamente elevados 30 dias após a cirurgia. No Grupo II, o colesterol plasmático e o glicogênio hepático apresentaram redu o no pós-operatório, enquanto os lipídios hepáticos estavam significativamente elevados. Comparando-se os 2 grupos, houve diferen a estatisticamente significativa nos valores do colesterol plasmático, do glicogênio e do índice de regenera ohepática. CONCLUS O: A anastomose porto-cava causa prejuízos morfológicos e bioquímicos significativos ao fígado, além de redu o significativa do peso corpóreo.

Abstract: OBJETIVO: Definir e classificar as varia es anat micas da jun o dos ductos cístico e hepático comum em fetos, analisando a freqüência, trajeto e rela o entre eles. MéTODOS: Dissecaram-se 33 fetos , no período de setembro de 1999 a julho de 2000, utilizando-se fotografias para registrar as jun es cístico-hepáticas. As uni es foram classificadas como alta, média e baixa e, quanto ao curso, paralelo ou angular. Constatado o tipo de uni o, aferiu-se o comprimento dos ductos. RESULTADOS: Visualizou-se a jun o cístico-hepática em 93,9% dos fetos, sendo encontrada a inser o média em 45,2% delas, a inser o alta em 29% e a inser o baixa em 25,8%. Quanto ao curso ductal, a uni o aguda foi observada em 71% dos fetos, enquanto a paralela, em 29%. Quanto ao comprimento ductal, o ducto cístico variou de 4 - 6 mm, o ducto hepático comum de 9 - 13 mm, e o ducto colédoco de 5 - 10 mm. CONCLUS O: Dentre as varia es anat micas, a inser o média foi a prevalente, seguida do curso angular, com comprimentos dos ductos cístico e hepático comum variando entre 6mm e 7 mm, respectivamente. Foi demonstrada uma freqüência significativa de inser o baixa cístico-hepático comum.
