RACIONAL: O envelhecimento da população é realidade sentida na vivência diária, levando à necessidade associada de prover cuidados médicos eletivos e de emergência a um número cada vez maior de idosos. OBJETIVO: Avaliar os aspectos clínicos, terapêuticos e evolutivos de pacientes idosos com obstrução intestinal atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP. MÉTODOS: Análise retrospectiva de pacientes internados no período de janeiro de 2002 a dezembro de 2006. Foram estudados 50 pacientes, 24 homens e 26 mulheres, com idade média de 74,7 ± 7,4 anos, analisando-se a diferenciação entre obstrução funcional e orgânica; a freqüência das causas obstrutivas; a mortalidade; a incidência dos sinais e sintomas; e correlação laboratorial. RESULTADOS: O quadro obstrutivo intestinal teve as seguintes causas: brida (38%), câncer de colon (24%), hérnias (12%), impactacão fecal (12%), carcinomatose (10%) e volvo da sigmóide (4%). A mortalidade foi de 18% associada à complicações infecciosas em todos os pacientes. CONCLUSÕES: a) A distinção entre a obstrução intestinal funcional e orgânica oferece dificuldade no idoso; b) o câncer do colon constitui-se em importante causa de obstrução intestinal com quadro obstrutivo já na primeira manifestação clínica desse tumor; c) bridas e hérnias são igualmente importantes na etiologia da obstrução intestinal; d) os sinais clínicos obstrutivos são poucos evidentes no idoso e a leucometria é mais fidedigna para este diagnóstico. BACKGROUND: Population aging is a reality that is experienced daily, leading to an associated need for providing elective and emergency medical care to an increasing number of elderly individuals. AIM: To evaluate clinical, therapeutic and developmental aspects of patients with intestinal obstruction assisted at the University Hospital of the Botucatu School of Medicine - UNESP. METHODS: Retrospective analysis of patients hospitalized from January 2002 to December 2006. A group of fifty patients comprising 24 males and 26 females at a mean age of 74.7 ± 7.4 years were studied. RESULTS: The main causes for intestinal obstruction were: adhesion (38%), colon cancer (24%), hernia (12%), fecal impaction (12%), carcinomatosis (10%) and sigmoid volvulus (4%). Mortality was of 18%, being associated with infection complications in all patients. CONCLUSIONS: a) The distinction between functional and organic intestinal obstruction in elderly individuals is difficult; b) Colon cancer is an important cause of intestinal obstruction, since obstructive conditions may be the first clinical manifestation of such tumors; c) Adhesion and hernia are equally important in the etiology of bowel obstruction, the former so being in terms of incidence and the latter in relation to the possibility of developing bowel strangling; d) The clinical signs of obstruction are not evident in elderly individuals and leukocyte count can be more reliable for this diagnosis.

RACIONAL: O carcinoma basalóide escamoso ocorre com maior freqüência no trato aerodigestivo superior e raramente acomete o esôfago. OBJETIVO: Apresentar os aspectos clínico-patológicos e os atributos imunoistoquímicos de um paciente com carcinoma basalóide escamoso do esôfago. RELATO DO CASO: Dos 134 pacientes com câncer do esôfago atendidos no Hospital Universitário de Botucatu-Unesp, São Paulo, de 1990 a 1999, somente um paciente (0,74%) apresentou carcinoma basalóide escamoso do esôfago. Tratava-se de paciente masculino, 41 anos, branco, lavrador com disfagia, regurgitação e emagrecimento há três meses. Referia tabagismo e etilismo há muitos anos. O esofagograma e o exame endoscópico revelaram lesão vegetante no terço distal do esôfago. A biópsia demonstrou neoplasia intraepitelial de alto grau associada a blocos de células basalóides que infiltravam o cório da mucosa, caracterizando o carcinoma basalóide escamoso. Os marcadores imunoistoquímicos foram positivos para o antígeno carcinoembriônico e para citoceratinas de alto peso molecular. A tomografia computadorizada revelou múltiplas metástases nos pulmões, fígado, e nódulos linfáticos regionais, documentando a fase avançada de evolução da doença. O tratamento consistiu apenas na realização de gastrostomia. O paciente apresentou queda acentuada do estado geral e evoluiu para óbito com quadro de melena quatro meses após o diagnóstico. CONCLUSÃO: O carcinoma basalóide escamoso é uma forma rara e agressiva de câncer do esôfago e o prognóstico depende do estadiamento da lesão e das condições clínicas do paciente no momento do diagnóstico. BACKGROUND: Basaloid squamous carcinoma is more frequently found in the upper aerodigestive tract, being rarely found in the esophagus. AIM: To present the pathological and clinical aspects, as well as immunhistochemical attributes of a basaloid squamous carcinoma of the esophagus patient. CASE REPORT: Of a total of 134 esophagus cancer patients in the Hospital Universitário de Botucatu-Unesp, in São Paulo, from 1990 through 1999, only one patient (0,74%), presented the basaloid squamous carcinoma of the esophagus. This patient, a 41 year-old Caucasian male farmer, presented dysfagia, regurgitation and weight loss for the last three months, being a smoker and alcoholic for many years. Endoscopy and esophagram revealed a vegetative lesion in the distal region of the esophagus. Biopsy showed a high-grade intra-epithelial neoplasm associated with basaloid cells infiltrating the corian mucosa, characteristic of the squamous basaloid carcinoma. Immunohistochemical markers were positive for carcinoembrionary antigen and high molecular weight citokeratins. Computerized tomography revealed multiple metastasis in the lungs, liver and regional lymphatic nodules, all evidence of an advanced evolution of the disease. Treatment consisted of gastrostomy. The patient presented an accentuated fall pertaining it's general state and died with a state of melena four months after diagnosis. CONCLUSION: The basaloid squamous carcinoma is a rare and aggressive form of esophagus cancer and the prognosis depends in the state at which the lesion is and in the clinical conditions of the patient at the time of diagnosis.

O tratamento dessa moléstia pode ser tanto conservador como reparador da lesão. Objetivo: Avaliar qual das intervenções leva a menor mortalidade. Método: Foi realizada uma revisão sistemática de estudos que contemplassem os dois tipos de tratamento em pacientes com perfuração esofágica não neoplásica e estudassem o desfecho mortalidade. Foram pesquisadas as principais bases de dados sem restrição de idiomas usando os termos “perfuração esofágica” AND “tratamento cirúrgico” AND “tratamento conservador”. Foi realizada metanálise com o programa Review Manager 5.4.1 utilizando-se efeito randômico. Foi planejada também a análise de subgrupos: perfuração cervical versus torácica, tempo de perfuração maior e menor que 24h, perfuração iatrogênica versus não iatrogênica e sutura versus esofagectomia na intervenção reparadora. A qualidade da evidência e força da recomendação foram avaliadas pelo sistema GRADE. Resultados: foram selecionados 40 estudos com 1673 participantes. Todos os estudos são série de casos que por sua natureza apresentam risco crítico de viés pelos potenciais confundidores associados à perfuração e também ao paciente. O desfecho mortalidade foi avaliado pelos 40 estudos. Não houve diferença no risco de morte entre os dois tipos de tratamento (RR= 1,15; IC 95% 0,88 a 1,52; I2= 0%). Em 11 estudos foi possível separar a mortalidade segundo a etiologia. Na etiologia iatrogênica, 201 participantes, não houve diferença na mortalidade entre as intervenções (RR 1,36, IC 95% 0,64 a 2,91, I2= 4%). Na etiologia não iatrogênica, 165 pacientes, não houve diferença na mortalidade entre as intervenções (RR 0,92, IC 95% 0,43 a 1,95, I2= 0%). Não houve diferença na mortalidade quando comparada a etiologia iatrogênica com a não iatrogênica (RR 0,68, IC 95% 0,42 a 1,10, I2= 8%). A comparação da mortalidade da perfuração cervical com a torácica, só foi possível em oito estudos, 306 participantes, e não houve diferença na mortalidade entre os grupos (RR 0,69, IC 95% 0,27 a 1,76, I2= 24%). A mortalidade segundo a intervenção cirúrgica foi possível em 21 estudos, 504 participantes. Não houve diferença no risco de morte entre sutura e esofagectomia (RR 0,62; IC 95% 0,32 a 1,20; I2= 24%). Não foi possível combinar os estudos quanto ao tempo de internação em enfermaria e UTI. A qualidade da evidência pelo sistema GRADE foi considerada muito baixa e a força da recomendação avaliada pelos oito itens que a regem mostra que os dois tratamentos podem ser recomendados. Conclusão: conclui-se que tanto o tratamento conservador como o tratamento cirúrgico pode ser recomendado. Não foi possível mostrar diferenças entre os subgrupos e nem do tempo de internação entre os dois tratamentos. SUMMARY Introduction: Esophageal perforation is a very serious event and requires immediate intervention so that it is not fatal. The treatment of this disease can be both conservative and repairing the lesion. Objective: To assess which of the interventions leads to the lowest mortality. Method: A systematic review of studies was performed that contemplated both types of treatment in patients with non-neoplastic esophageal perforation and studied the mortality outcome. The main databases without language restrictions were searched using the terms “esophageal perforation” AND “surgical treatment” AND “conservative treatment”. Meta-analysis was performed with the Review Manager 5.4.1 program using random effect. The analysis of subgroups was also planned: cervical versus thoracic perforation, perforation time longer and shorter than 24h, iatrogenic versus non-iatrogenic perforation, and suture versus esophagectomy in the reparative intervention. The quality of evidence and strength of recommendation were assessed using the GRADE system. Results: 40 studies were selected with 1673 participants. All studies are case series that, by their nature, present a critical risk of bias due to potential confounders associated with perforation and also with the patient. The mortality outcome was evaluated by the 40 studies. There was no difference in the risk of death between the two types of treatment (RR= 1.15; 95% CI 0.88 to 1.52; I2= 0%). In 11 studies it was possible to separate mortality according to etiology. In the iatrogenic etiology, 201 participants, there was no difference in mortality between interventions (RR 1.36, 95% CI 0.64 to 2.91, I2= 4%). In the non-iatrogenic etiology, 165 patients, there was no difference in mortality between interventions (RR 0.92, 95% CI 0.43 to 1.95, I2= 0%). There was no difference in mortality when comparing iatrogenic and non-iatrogenic etiologies (RR 0.68, 95% CI 0.42 to 1.10, I2= 8%). Comparison of mortality from cervical perforation with thoracic perforation was only possible in eight studies, 306 participants, and there was no difference in mortality between the groups (RR 0.69, 95% CI 0.27 to 1.76, I2= 24 %). Mortality according to surgical intervention was possible in 21 studies, 504 participants. There was no difference in the risk of death between suture and esophagectomy (RR 0.62; 95% CI 0.32 to 1.20; I2= 24%). It was not possible to combine the studies regarding the length of stay in the ward and the ICU. The quality of evidence by the GRADE system was considered very low and the strength of the recommendation evaluated by the eight items that govern it shows that both treatments can be recommended. Conclusion: it is concluded that both conservative treatment and surgical treatment can be recommended. It was not possible to show differences between the subgroups or the length of stay between the two treatments.

No. of bitstreams: 1 oliveira_gc_me_bot.pdf: 1986545 bytes, checksum: 30251ce489fc004d4e0446c3d2fba4ce (MD5) Previous issue date: 2022-05-25 Objetivos: Avaliar os eventuais benefícios do pré-condicionamento isquêmico (PCI) na cirurgia hepática e no transplante hepático, por meio de revisão sistemática da literatura com metanálise, e avaliar a sua aplicabilidade na prática clínica. Métodos: Foram realizadas buscas de artigos relacionados ao tema nas línguas Portuguesa, Inglesa e Espanhola, indexados ao MEDLINE (Literatura Internacional em Ciências e Saúde) via PubMED, LILACS (Literatura Latino Americana e do Caribe em Ciências da Saúde), SCOPUS, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), SciELO, WEB OF SCIENCE, e PubMED, e fontes adicionais de ensaios publicados e não publicados. Resultados: As buscas forneceram um total de 2077 artigos, dos quais foram selecionados 17 relacionados à Cirurgia Hepática, e 13 ao transplante hepático, que totalizaram 1052 pacientes submetidos a ressecções hepáticas e 660 pacientes submetidos a transplante hepático. A aplicação do PCI não altera o tempo cirúrgico das ressecções hepáticas e dos transplantes hepáticos. Os pacientes do grupo PCI submetidos a hepatectomias apresentaram menor sangramento (Diferença Média de -49.97 ml, IC 95%, -86.32 a -13.6, I²: 64%) e o número de pacientes que necessitaram de transfusão sanguínea também foi menor nesse grupo (RR 0.71, IC 95%, 0.53 a 0.96; I²=0%). Ainda em relação à cirurgia hepática o PCI reduziu o risco de ascite no pós-operatório (RR 0.40, IC 95%, 0.17 a 0.93; I²=0%). Já em relação à aplicação do PCI no transplante hepático, o grupo submetido ao PCI apresentou menor risco de trombose da artéria hepática no pós-operatório (RR 0.22, IC 95%, 005 a 1.0; I²=0%) e menor pico nas dosagens pós-operatórias de AST (DM – 228.22, IC 95%, -414.24 - 42.20; i² 70%) e ALT (DM -213.80, IC 95%, -379.29 a -48.31; I²=48%). Os demais desfechos não sofreram alterações estatisticamente significativas ou tiveram suas metanálises consideradas como impróprias devido à heterogeneidade elevada. Conclusão: O PCI é aplicável na prática clínica tanto para pacientes submetidos a ressecções hepáticas, quanto para pacientes submetidos a transplantes hepáticos, com algum efeito benéfico. Porém, não encontramos evidências suficientes para estimular sua utilização como rotina. Objective: Assess the possible benefits of ischemic preconditioning (IPC) in liver surgery and liver transplantation, through a systematic review of the literature with meta-analysis, and to evaluate its applicability in clinical practice. Methods: Searches were carried out for articles related to the topic in Portuguese, English and Spanish, indexed to MEDLINE (Medical Literature Analysis and Retrievel System Online) via PUBMED, LILACS (Latin American and Caribbean Literature Health Sciences), SCOPUS, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), SciELO, WEB OF SCIENCE, PubMED, and additional sources of published and unpublished trials. Results: The searches yielded a total of 1753 articles, of which 17 related to Liver Surgery and 12 to liver transplantation were selected, totaling 1052 patients undergoing liver resections and 535 patients undergoing liver transplantation. The application of IPC does not change the surgical time of liver resections and liver transplants. Patients in the IPC group undergoing hepatectomies had less bleeding (Mean Difference -49.97 ml, 95% CI, -86.32 to -13.6, I²: 64%) and the number of patients requiring blood transfusion was also lower in this group (RR 0.71, 95% CI, 0.53 to 0.96; I²=0%). Still in relation to liver surgery, IPC reduced the risk of ascites in the postoperative period (RR 0.40, 95% CI, 0.17 to 0.93; I²=0%). Regarding the application of IPC in liver transplantation, the group undergoing IPC had a lower risk of postoperative hepatic artery thrombosis (RR 0.22, 95% CI, 005 to 1.0; I²=0%) and a lower peak in the postoperative dosages of AST (MD – 228.22, 95% CI, -414.24 - 42.20; i² 70%) and ALT (MD -213.80, IC 95%, -379.29 a -48.31; I²=48%). The other outcomes did not undergo statistically significant changes or have had their meta-analysis considered inadequate due to high heterogeneity. Conclusion: IPC is applicable in clinical practice both for patients undergoing liver resections and for patients undergoing liver transplantation, with some beneficial effect. However, we did not find sufficient evidence to encourage its routine use.

Orientador: Luiz Roberto Lopes Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: O tratamento do Tumor Estromal do Trato Gastrointestinal (GIST) tem se aprimorado muito na última década como resultado das pesquisas biomoleculares e o uso adjuvante dos inibidores das tirosinas quinases. Entretanto, nos hospitais públicos brasileiros nem sempre são disponíveis tais ferramentas. Objetivo: Avaliar o perfil dos pacientes portadores de GIST em hospital público oncológico - Hospital Amaral Carvalho (HAC)- Jaú-SP. Métodos: Análise retrospectiva de todos os casos de GIST tratados no HAC no período de 2001 a 2013. Resultados: Foram analisados 69 pacientes, com média de idade de 59 anos e com discreto predomínio no sexo feminino (51%). A principal forma de apresentação clínica foi dor abdominal associada com achado de exame de imagem. O aparecimento de uma segunda neoplasia nos pacientes estudados portadores de GIST ocorreu em 26,1% dos casos. A positividade do CD117 foi de 97,1%. A localização mais frequente foi o estômago em 55% dos casos. A ressecção R0 foi possível em 81,1% dos casos e a taxa de recidiva foi de 23,2%, sendo fígado e peritôneo os sítios principais acometidos. A sobrevida global na amostra toda foi de 74% em 5 anos. A taxa de sobrevida livre de doença foi de 69%. A utilização do imatinibe ficou restrita aos pacientes com doença residual (ressecção R2, R1 ou metastáticos), irressecáveis ou com recidiva. Conclusão: Na análise desta série de pacientes portadores de GIST, quanto aos dados de diagnóstico, tratamento cirúrgico associado ou não ao uso do imatinibe, taxas de complicações, recidivas e sobrevida, são semelhantes aos dados encontrados na literatura, apesar de não dispormos de todos os métodos de estudo molecular do tumor e de terapêutica adjuvante para os casos considerados de alto risco. No entanto, a estratificação clínica e biomolecular otimiza a modalidade de tratamento ao paciente. Deste modo, políticas de incentivo para disponibilizar tal método e tratamento são necessárias Abstract: There is an improvement on GIST treatment in the last decade due to bimolecular reseach and adjvant therapy with tyrosine kinases inhibitors. However, both modalities of treatment rarely are available in brazilian public hospital. Objective: We aim to evaluate patients carriers GIST in a public oncologic hospital - Amaral Carvalho Hospital (ACH) - Jau-SP. Methods: A retrospective study was made concerning patients with GIST diagnosis treated in the ACH between 2001 and 2013. Results: Sixty nine patients with GIST diagnosis were included, mean age 59 years and slight predominance in females (51%). The main symptom was abdominal pain associated with incidental finding imaging. The appearance of a second tumor in the patients studied with GIST occurred in 26.1 %. CD117 positivity was 97.1 %. The most frequent location was at the stomach in 55% of cases. R0 resection was possible in 81.1 % of cases and recurrence rate was 23.2 %, with liver and peritoneum being the main sites affected. Five years overall survival in the whole sample was 74%. Free survival rate of disease was 69%. Imatinib treatment was limited to patients with residual disease (unresectable disease, R2 and R1 resection), metastatic disease or recurrence. The use of adjuvant treatment was not possible as the risk stratification due to current legislation in the Health System. Conclusion: The analysis of this series of patients with GIST, as the diagnostic data, surgical treatment with or without the use of imatinib, rates of complications, recurrence and survival, are similar to data found in literature, although we do not have all the molecular tumor study methods and adjuvant therapy for cases considered high risk. However, clinical or biomolecular stratification optimizes the mode of treatment to the patient. Thus, incentive programs to provide such a method and adjuvant therapy are needed Mestrado Fisiopatologia Cirúrgica Mestre em Ciências

- Abstract
Context: Correction of voluminous hernias and large abdominal wall defects is a big challenge in surgical practice due to technical difficulties and the high incidence of respiratory and cardiovascular complications., Objectives: To present the authors experience with inducing progressive pneumoperitoneum preoperative to surgical treatment of voluminous hernias of the abdominal wall., Methods: Retrospective study of six patients who presented voluminous hernias of the abdominal wall and were operated after installation of a pneumoperitoneum. The procedure was performed by placing a catheter in the abdominal cavity at the level of the left hypochondrium with ambient air insufflation for 10 to 15 days., Results: Four of the six patients were female and two male. Ages ranged from 42 to 62 years. Hernia duration varied from 5 to 40 years. Four patients had incisional, one umbilical, and one inguinal hernias. Mean pneumoperitoneum time was 11.6 days. There were no complications related to pneumoperitoneum installation and maintenance. All hernias were corrected without technical difficulties. The Lichtenstein technique was used to correct the inguinal hernia, peritoneal aponeurotic transposition for one of the incisional hernias, with the rest corrected using polypropylene mesh. One death and one wall infection were observed post operatively. No recurrences were reported until now, in 4 to 36 months of follow-up., Conclusion: Preoperative progressive pneumoperitoneum is a safe and easy executed procedure, which simplifies surgery and reduces post-operative respiratory and cardiovascular complications. It is indicated for patients with hernias that have lost the right of domain in the abdominal cavity.
