ABSTRACT

Abstract Purpose: To evaluate the outcome of transhiatal esophagectomy without thoracotomy and with preservation of the vagal trunks for the treatment of advanced megaesophagus. Methods: Between March 2006 and September 2017, it was performed 136 transhiatal esophagectomies without thoracotomy by laparoscopy, with preservation of the vagus nerves. All patients were evaluated pre and postoperatively for respiratory and nutritional aspects Post operatively, some surgical aspects were evaluated like radiology and endoscopy of the digestive tract. Results: Follow-up for 7 months to 12 years by clinical, radiologic, endoscopic and pH monitoring revealed satisfactory and encouraging outcomes of the procedure. Conclusion: The laparoscopic transhiatal esophagectomy is a feasible and safe technique with good postoperative outcomes.

ABSTRACT

Abstract Purpose: To compare pulmonary and nutritional parameters before and after inspiratory muscle training (IMT) and enteral feeding support in patients with esophageal disease undergoing preoperative outpatient follow-up. Methods: Thirty patients with a mean age of 55.83 years, 16 men and 14 women, were included. Pulmonary assessment consisted of the measurement of MIP, MEP, and spirometry. Anthropometric measurements and laboratory tests were performed for nutritional assessment. After preoperative evaluation, inspiratory muscle training and enteral nutrition support were started. A p<0.05 was considered statistically significant. Results: After an outpatient follow-up period of 4 weeks, a significant increase in MIP (-62.20 ± 25.78 to -81.53 ± 23.09), MEP (73.4 ± 31.95 to 90.33 ± 28.39), and FVC (94.86 ± 16.77 to 98.56 ± 17.44) was observed. Regarding the anthropometric variables, a significant increase was also observed in BMI (20.18 ± 5.04 to 20.40 ± 4.69), arm circumference (23.38 ± 3.28 to 25.08 ± 4.55), arm muscle circumference (21.48 ± 3.00 to 22.07 ± 3.36), and triceps skinfold thickness (5.62 ± 2.68 to 8.33 ± 6.59). Conclusion: Pulmonary and nutritional preparation can improve respiratory muscle strength, FVC and anthropometric parameters. However, further studies are needed to confirm the effectiveness of this preoperative preparation.

ABSTRACT

ABSTRACT Background: Cholelithiasis is one of the diseases with greater surgical indication. Currently, laparoscopic cholecystectomy is the gold standard in the treatment of cholelithiasis. Aim: To analyze the culture of bile from patients with cholelithiasis, mainly in the occurrence of brown and mixed stones. Methods: Was carried out a prospective study with 246 cases with biliary lithiasis who underwent elective laparoscopic cholecystectomy. Bile culture was performed in all. During anesthetic induction the patients received a single dose of intravenous cefazolin 1 g. At the end of the surgery, the gallbladder was punctured, its contents extracted and immediately placed in a sterile 20 ml propylene flask and promptly sent to bacterioscopy with Maconkey and blood agars. Incubation at 37° C for 24 h was carried out. A protocol was elaborated to include the main factors potentially related to cholelithiasis and the possible presence of associated bacterial infection. Results: Of the 246 patients, 201 had negative bile culture and 45 positive. Of the 45 patients with bacteriobilia, 34 had growth of a single type of bacterium in bile culture and 11 more than one. Conclusions: It was observed a relationship between bacteriobilia and age, suggesting that age is a risk factor for bacteriobilia. The use of antibiotic prophylaxis in the elderly is therefore recommended.


RESUMO Racional: A colecistolitíase é uma das doenças que têm maior indicação cirúrgica. Atualmente a colecistectomia laparoscópica é o padrão-ouro no seu tratamento. Objetivo: Analisar a cultura da bile de pacientes portadores de colecistolitíase, principalmente na ocorrência de cálculos com pigmentos marrons e mistos. Métodos: Foi realizado estudo prospectivo de 246 casos de pacientes portadores de litíase biliar, submetidos à colecistectomia laparoscópica eletiva, sendo realizada cultura da bile. Durante a indução anestésica os pacientes receberam dose única de cefazolina 1 g, intravenosa. No final da operação foi puncionada a vesícula biliar, extraído seu conteúdo e imediata colocação em frasco estéril de propileno de 20 ml e prontamente encaminhado para bacterioscopia com semeadura do material coletado em ágar sangue e de Maconkey com posterior incubação em estufa de cultura a 37° C durante 24 h. Foi elaborado um protocolo capaz de englobar os principais fatores potencialmente relacionados à colecistolitíase e a possível presença de infecção bacteriana associada. Resultados: Dos 246 participantes, 201 tiveram cultura de bile negativa e 45 positiva. Dos 45 pacientes com bacteriobilia, 34 tiveram crescimento de um único tipo de bactéria e 11 mais de uma. Conclusões: Foi observada relação entre bacteriobilia e a idade, sugerindo que a idade é fator de risco para bacteriobilia. Recomenda-se assim o emprego de antibioticoprofilaxia nos idosos.

ABSTRACT

Abstract Introduction: Diabetes Mellitus (DM) is a multifactorial metabolic disorder. As considered a public health problem needing additional treatment options. Objective: This prospective study aimed at evaluating pulmonary function through spirometry, before and after metabolic surgery without gastric resection in type 2 DM patients. Methods: Sample was composed by 17 type 2 DM females. They were analyzed in pre (24 hours before surgical procedure), immediate post-operative period POST1 (24 hours after surgical procedure) and in the late postoperative period POST2 (two years after surgical procedure). Besides statistical analysis, it was evaluated the following spirometric parameters: forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and the FEV1 / FVC ratio (%). Results: Spirometric parameters showed a value increase when compared PRE and POS2 values, except for FVC and FEV1, which was not statistically significant. Conclusion: Type 2 DM women submitted to metabolic surgery without gastric resection showed spirometric value increased after two-year surgical procedure, when compared to preoperative period values. It is important additional studies about pulmonary function, diabetic patients and metabolic surgery without gastric resection.


Resumo Introdução: O Diabetes Mellitus (DM) é uma desordem metabólica multifatorial. Considerado um problema de saúde pública necessita de opções de tratamento adicionais. Objetivo: Este estudo prospectivo avaliou a função pulmonar, através da espirometria, antes e após a cirurgia metabólica sem ressecção gástrica em pacientes com diabetes mellitus tipo 2. Métodos: A amostra foi composta por 17 mulheres com diabetes mellitus tipo 2. Elas foram avaliadas no PRE (24 horas antes da cirurgia), pós-operatório imediato POST1 (24 horas após a cirurgia) e no pós-operatório tardio POST2 (dois anos após a cirurgia). Além da análise estatística, foram avaliados os seguintes parâmetros expirométricos: capacidade vital forçada (CVF), volume expiratório forçado no primeiro segundo (VEF1) e relação VEF1/CVF (%). Resultados: os parâmetros expirométricos aumentaram quando comparados aos valores PRE e POS2, exceto para CVF e VEF1, os quais não foram estatisticamente significativos. Conclusão: Mulheres diabéticas tipo 2 que realizaram cirurgia metabólica sem ressecção gástrica aumentaram o valor expirométrico após dois anos do procedimento cirúrgico, quando comparadas aos valores no pré-operatório. Estudos adicionais são importantes sobre a função pulmonar, diabetes e cirurgia metabólica sem ressecção gástrica.

ABSTRACT

Abstract Purpose: To evaluate respiratory muscle strength (PImax and PEmax) before and 24 and 48 h after conventional and single-port laparoscopic cholecystectomy. Methods: Forty women with symptomatic cholelithiasis (18 to 70 years) participated in the study. The patients were divided into two groups: 21 patients undergoing conventional laparoscopic cholecystectomy and 19 patients undergoing single-port laparoscopic cholecystectomy. Differences were considered to be significant when p<0.05. Results: The results showed a greater decline in PImax after 24 h in the group submitted to conventional laparoscopic cholecystectomy, with a significant difference between groups (p=0.0308). Conclusion: Recovery of the parameters studied was more satisfactory and respiratory muscle strength was less compromised in the group submitted to single-port laparoscopic cholecystectomy.

ABSTRACT

ABSTRACT BACKGROUND Morbid obesity is a multifactorial disease that is increasingly treated by surgery. OBJECTIVE To evaluate gastric histopathological changes in obese, and to compare with patients who underwent gastrojejunal bypass and the jejunal mucosa after the surgery. METHODS This is an observational study performed at a tertiary public hospital, evaluating endoscopic biopsies from 36 preoperative patients and 35 postoperative. RESULTS In the preoperative group, 80.6% had chronic gastritis, which was active in 38.9% (77.1% and 20.1%, respectively, in the postoperative). The postoperative group had a significant reduction in Helicobacter pylori infection (P=0.0001). A longer length of the gastric stump and a time since surgery of more than two years were associated with Helicobacter pylori infection. The jejunal mucosa was normal in 91.4% and showed slight nonspecific chronic inflammation in 8.6%. CONCLUSION There was a reduction in the incidence of Helicobacter pylori infection in the postoperative group. A longer length of the gastric stump and longer time elapsed since surgery were associated with Helicobacter pylori infection. The jejunal mucosa was considered normal in an absolute majority of patients.

ABSTRACT

O melanoma maligno corresponde a 5% de todas as neoplasias da pele. Apresenta elevada agressividade local e tendência à disseminação através de metástases. O aparelho digestivo não é sítio secundário comum de melanoma, e o estômago é raramente comprometido. Relatamos caso de paciente do sexo masculino, 64 anos, com quadro de astenia progressiva, anemia, episódio de síncope e história de exérese de melanoma maligno nível IV de Clark em asa nasal há 6 anos, com esvaziamento de cadeia linfonodal cervical ipsilateral. Durante a investigação, foi encontrada massa gástrica, sendo submetido à gastrectomia total com reconstrução em Y de Roux, com melhora substancial dos sintomas. O exame anatomopatológico da massa gástrica confirma o resultado de metástase de melanoma maligno pela biópsia endoscópica pré-operatória. O paciente segue em acompanhamento ambulatorial sem manifestações de novas metástases até o momento. (AU)


Malignant melanoma accounts for 5% of all skin cancers. It has high local aggressiveness and tendency to spread through metastases. The digestive tract is not common secondary site of melanoma, and the stomach is rarely compromised. We report the case of a male patient, 64, with progressive asthenia, anemia, syncope and previously excision of malignant melanoma Clark level IV in nasal wing for 6 years with ipsilateral cervical lymph node emptying. During the investigation we found gastric mass and underwent total gastrectomy and Roux-en-Y with substantial improvement in symptoms. The anatomopathological examination of the gastric mass confirms the result of malignant melanoma metastasis by the preoperative endoscopic biopsy. The patient is in outpatient treatment without signs of new metastases so far. (AU)

ABSTRACT

ABSTRACT Background: Surgical treatment of GERD by Nissen fundoplication is effective and safe, providing good results in the control of the disease. However, some authors have questioned the efficacy of this procedure and few studies on the long-term outcomes are available in the literature, especially in Brazil. Aim: To evaluate patients operated for gastro-esophageal reflux disease, for at least 10 years, by Nissen fundoplication. Methods: Thirty-two patients were interviewed and underwent upper digestive endoscopy, esophageal manometry, 24 h pH monitoring and barium esophagogram, before and after Nissen fundoplication. Results: Most patients were asymptomatic, satisfied with the result of surgery (87.5%) 10 years after operation, due to better symptom control compared with preoperative and, would do it again (84.38%). However, 62.5% were in use of some type of anti-reflux drugs. The manometry revealed lower esophageal sphincter with a mean pressure of 11.7 cm H2O and an average length of 2.85 cm. The average DeMeester index in pH monitoring was 11.47. The endoscopy revealed that most patients had a normal result (58.06%) or mild esophagitis (35.48%). Barium swallow revealed mild esophageal dilatation in 25,80% and hiatal hernia in 12.9% of cases. Conclusion: After at least a decade, most patients were satisfied with the operation, asymptomatic or had milder symptoms of GERD, being better and with easier control, compared to the preoperative period. Nevertheless, a considerable percentage still employed anti-reflux medications.


RESUMO Racional: O tratamento cirúrgico para DRGE empregando a fundoplicatura à Nissen é eficaz e seguro, oferecendo bons resultados no controle da doença. Entretanto, alguns autores têm questionado quanto a sua eficácia, e poucos estudos com avaliação tardia destes doentes são encontrados na literatura, sobretudo no Brasil. Objetivo: Avaliar pacientes operados por doença do refluxo gastroesofágico há pelo menos 10 anos, pela técnica de Nissen. Métodos: Trinta e dois pacientes foram entrevistados e submetidos à endoscopia digestiva alta, manometria esofágica, pHmetria prolongada de 24h e esofagograma baritado, antes e após a fundoplicatura à Nissen. Resultados: A maioria estava assintomático 10 anos após a operação e satisfeitos com o resultado dela (87,5%) e a fariam novamente (84,38%), devido melhor controle sintomático com medicação, em comparação com o período pré-operatório. Entretanto, 62,5% empregavam algum tipo de medicação anti-refluxo. Quanto aos exames, a manometria revelou extensão média de 2,85 cm de esfíncter esofágico inferior, com pressão média de 11,7 cm de H2O. O índice médio de DeMeester na pHmetria foi de 11,47. Na endoscopia a maior parte dos pacientes apresentou exame normal (58,06%), ou esofagite leve (35,48%). O esofagograma revelou discreta dilatação esofágica em 25,80% e hérnia hiatal em 12,9% dos casos. Conclusão: Após no mínimo uma década, a maioria dos doentes estava satisfeita com a operação, assintomática ou apresentava sintomatologia mais branda da DRGE que era de melhor e mais fácil controle, comparado ao período pré-operatório. Porcentagem não desprezível ainda empregava medicações para refluxo.

ABSTRACT

Background: Immunological and inflammatory mechanisms play a key role in the development and progression of type 2 diabetes mellitus. Aim: To raise the hypothesis that alterations in immunological parameters occur after duodenojejunal bypass surgery combined with ileal interposition without gastrectomy, and influences the insulin metabolism of betacells. Methods: Seventeen patients with type 2 diabetes mellitus under clinical management were submitted to surgery and blood samples were collected before and six months after surgery for evaluation of the serum profile of proinflammatory (IFN-γ, TNF-α, IL-17A) and anti-inflammatory cytokines (IL-4, IL-10). In addition, anthropometric measures, glucose levels and insulin use were evaluated in each patient. Results: No changes in the expression pattern of proinflammatory cytokines were observed before and after surgery. In contrast, there was a significant decrease in IL-10 expression, which coincided with a reduction in the daily insulin dose, glycemic index, and BMI of the patients. Early presentation of food to the ileum may have induced the production of incretins such as GLP-1 and PYY which, together with glycemic control, contributed to weight loss, diabetes remission and the consequent good surgical prognosis of these patients. In addition, the control of metabolic syndrome was responsible for the reduction of IL-10 expression in these patients. Conclusion: These findings suggest the presence of low-grade inflammation in these patients during the postoperative period, certainly as a result of adequate glycemic control and absence of obesity, contributing to a good outcome of surgery.


Racional: Mecanismos imunológicos e inflamatórios desempenham papel-chave no desenvolvimento e progressão do diabete melito tipo 2. Objetivo: Levantar a hipótese de que alterações nos parâmetros imunológicos ocorrem após operação duodenojejunal combinada com interposição ileal sem gastrectomia, e influenciam o metabolismo da insulina das células beta. Métodos: Dezessete pacientes com diabete melito tipo 2 sob manejo clínico foram submetidos à cirurgia e amostras de sangue foram coletadas antes e seis meses após para avaliação do perfil de sorológico de citocinas pró-inflamatórias (IFN-γ, TNF-α, IL-17A) e anti-inflamatórias(IL-4, IL-10). Além disso, parâmetros antropométricos, glicemia e uso de insulina foram avaliados em cada paciente. Resultados: Não ocorreram alterações no padrão de expressão de citocinas pró-inflamatórias observadas antes e depois da operação. Em contraste, houve diminuição significativa na expressão de IL-10, que coincide com redução da dose diária de insulina, com o controle glicêmico e redução do IMC dos pacientes. Apresentação precoce de alimentos para o íleo pode ter induzido a produção das incretinas tais como GLP-1 e PYY, que, juntamente com o controle da glicemia, contribuíram para a perda de peso, remissão do diabete e o bom prognóstico consequente cirúrgico. Além disso, o controle de síndrome metabólica foi responsável pela redução da expressão de IL-10 nestes doentes. Conclusão: Baixo grau de inflamação estava presente nesses pacientes no pós-operatório, certamente pelo adequado controle glicêmico e ausência de obesidade, o que contribuiu para bom resultado cirúrgico.

ABSTRACT

BACKGROUND: Incretins are hormones produced by the intestine and can stimulate the secretion of insulin, helping to diminish the post-prandial glycemia. The administration of an emulsion of palm oil can help in the maintenance of the weight, and can increase circulating incretins levels. Glutamine increases the concentration of incretins in diabetic people. Both can help in metabolic syndrome. AIM: To analyze the effects of ingestion of palm oil and glutamine in glycemia and in incretins in patients with diabetes submitted to surgical duodenojejunal exclusion with ileal interposition without gastrectomy. METHODS: Eleven diabetic type 2 patients were included and were operated. They were called to laboratory follow-up without eating anything between eight and 12 hours. They had there blood collected after the stimulus of the palm oil and glutamine taken in different days. For the hormonal doses were used ELISA kits. RESULTS: The glycemia showed a meaningful fall between the fast and two hours after the stimulus of the palm oil (p=0,018). With the glutamine the GLP-1 showed an increase between the fast and one hour (p=0,32), the PYY showed an important increase between the fast and one hour after the stimulus (p=0,06), the glycemia showed a meaningful fall after two hours of the administration of the stimulus (p=0,03). CONCLUSION: Palm oil and glutamine can influence intestinal peptides and glucose .


RACIONAL: A administração de óleo de palma auxilia na manutenção do peso e aumenta níveis de incretinas circulantes. A glutamina aumenta a concentração de incretinas em indivíduos diabéticos. Assim, eles podem influenciar no tratamento da síndrome metabólica. OBJETIVO: Analisar os efeitos da ingestão de óleo de palma e glutamina na glicemia e incretinas em pacientes diabéticos que foram submetidos à operação de exclusão duodenojejunal com interposição ileal sem gastrectomia. MÉTODOS: Participaram 11 pacientes, portadores de diabete melito tipo 2, que foram operados com exclusão duodenojejunal com interposição ileal sem gastrectomia. Foram convocados para comparecer ao laboratório em jejum de oito a 12 horas e submetidos ao procedimento de coleta de sangue após os estímulos de óleo de palma e glutamina via oral em dias distintos. Para as dosagens hormonais foram utilizados kits de ELISA. RESULTADOS: A glicemia apresentou queda significativa entre o jejum e duas horas após o estímulo de óleo de palma (p=0,018). Com a glutamina, o GLP-1 apresentou aumento entre o jejum e uma hora (p=0,32); o PYY apresentou aumento entre o jejum e uma hora após o estímulo (p=0,06); a glicemia apresentou queda significativa após duas horas da administração do estímulo (p=0,03). CONCLUSÃO: O óleo de palma e a glutamina podem influenciar os peptídeos intestinais e na glicemia .

ABSTRACT

PURPOSE: To investigate clinical, laboratory and ultrasonographic parameters in patients with and without preoperative criteria for intraoperative cholangiography (IOC) during laparoscopic cholecystectomy in order to define predictive factors of choledocolithiasis. METHODS: As a criterion for inclusion in the study the patients should present chronic calculous cholecystitis in the presence or absence of any recent clinical, laboratory of ultrasonographic finding suggesting choledocolithiasis, who were therefore submitted to cholangiography during surgery. RESULTS: A total of 243 laparoscopic cholecystectomies with IOC were performed on patients with chronic calculous cholecystitis with or without a preoperative formal indication for contrast examination. Choledocolithiasis was detected in 33 (13.58%) of the 243 patients studied. The incidence of previously unsuspected choledocolithiasis was only one case (1.0%) among 100 patients without an indication for this exam. However, 32 (22.37%) cases of choledocolithiasis were observed among the 143 patients with a preoperative indication for IOC. CONCLUSION: The use of selective cholangiography is safe for the diagnosis of choledocolithiasis. Only 22.37% of the cholangiography results were positive in cases of suspected choledocolithiasis.

ABSTRACT

OBJETIVO: Comparar as alterações anatômicas decorrentes de um quadro de icterícia obstrutiva experimental induzida em suínos nos períodos pré e pós-operatório por meio de exame ultrassonográfico.MATERIAIS E MÉTODOS: Seis suínos da raça Landrace, com 36 dias de idade, foram submetidos a obstrução biliar completa mediante ligadura do ducto colédoco por cirurgia videolaparoscópica.RESULTADOS: Não ocorreram dificuldades na execução dos procedimentos obstrutivos e a recuperação cirúrgica foi eficiente. Decorridos sete dias, os animais apresentaram icterícia, bilirrubinúria e acolia fecal. O exame ultrassonográfico comparativo permitiu visualizar hepatomegalia, colecistomegalia e aumento no calibre do ducto colédoco em todos os animais, assim como alterações decorrentes da colestase. A avaliação morfométrica revelou aumento significativo nos diâmetros da vesícula biliar e do lobo hepático lateral esquerdo.CONCLUSÃO: Os suínos representam um modelo experimental adequado de icterícia obstrutiva, e o exame ultrassonográfico demonstrou-se sensível e relevante no diagnóstico das alterações decorrentes de obstrução biliar extra-hepática nesses animais.


OBJECTIVE: To compare, by means of ultrasonography, pre- and postoperative anatomical changes arising from experimentally induced obstructive jaundice in porcine models.MATERIALS AND METHODS: Six 36-day-old Landrace pigs underwent laparoscopically induced complete biliary obstruction by common bile duct ligation.RESULTS: No difficulty was faced during the procedures and the surgical recovery was uneventful. After seven days, the animals showed jaundice, bilirubinuria and acholic stools. Comparative ultrasonography allowed visualization of hepatomegaly, cholecystomegaly and increased caliber of the common bile duct in all the animals, as well as changes resulting from cholestasis. The morphometric analysis revealed a significant increase in diameter of the gallbladders and left lateral liver lobes.CONCLUSION: Pigs represent appropriate experimental models for investigation of obstructive jaundice, and ultrasonography has shown to be sensitive, playing a relevant role in the diagnosis of extrahepatic biliary obstruction in such animals.

ABSTRACT

PURPOSE: Evaluate anatomical and functional changes of the esophageal stump and gastric fundus of patients with advanced megaesophagus, submitted to laparoscopic subtotal esophagectomy. METHODS: Twenty patients with advanced megaesophagus, previously submitted to a videolaparoscopic subtotal esophagectomy , were evaluated. Were conducted: radiological evaluation of the stump esophagus with transposed stomach, electromanometric, endoscopic examination and histopathology of the esophageal stump and gastric fundus, without making gastric tube or pyloroplasty. RESULTS: It was observed that the average height and pressure of the anastomosis, in the electromanometric evaluation, were 23.45cm (±1.84cm) and 7.55mmHg (±5.65mmHg). In patients with megaesophagus III, the pressure of the anastomosis was 10.91mmHg (±6.33mmHg), and pressure from the UES, 31.89mmHg (±14.64mm Hg), were significantly higher than those in grade IV. The pathological evaluation detected mild esophagitis in 35% of patients, moderate in 20% and acanthosis glicogenica in 45%. The examination of the gastric fundus showed that 50% of patients were infected with Helicobacter pylori. Chronic gastritis occurred in 95% of the patients. CONCLUSIONS: The laparoscopic esophagectomy shown to be effective in the treatment of advanced achalasia. The cervical level anastomosis protects the esophageal stump from the aggression resulted from gastric reflux after the esophagectomy.


OBJETIVO: Avaliar as alterações anatômicas e funcionais do coto esofágico e fundo gástrico de pacientes com megaesôfago avançado, submetidos à esofagectomia subtotal laparoscópica. MÉTODOS: Vinte pacientes com megaesôfago avançado, previamente submetidos à esofagectomia subtotal videolaparoscópica, foram avaliados. Foram realizados: avaliação radiológica do coto esofágico com o estômago transposto, eletromanometria endoscopia e exame histopatológico do coto esofágico e fundo gástrico,sem fazer tubo gástrico ou piloroplastia. RESULTADOS: Observou-se que a altura média e pressão da anastomose, na avaliação eletromanométrica, foram: 23,45cm (± 1,84cm) e 7,55mmHg (± 5,65mmHg), Em pacientes com megaesôfago III, a pressão da anastomose foi de 10,91mmHg (± 6,33mmHg), e a pressão do ESE, 31,89mmHg (±14,64mmHg) foram significativamente mais elevados do que aqueles em grau IV. A avaliação patológica detectou esofagite leve em 35% dos pacientes, moderada em 20% e acantose glicogênica em 45%. O exame do fundo gástrico mostrou que 50% dos pacientes foram infectados com Helicobacter pylori. Gastrite crônica ocorreu em 95% dos pacientes. CONCLUSÕES: A esofagectomia laparoscópica mostrou-se eficaz no tratamento de acalasia avançada. A anastomose em nível cervical tem um papel protetor para o coto esofágico ao evitar a agressão resultante de refluxo gástrico após a esofagectomia.

ABSTRACT

PURPOSE: To induce a total extra-hepatic obstructive jaundice in swines, by ligation of the common bile duct by laparoscopic surgery. METHODS: Eight swines of the Landrace race, 36-day-old, originated from the same matrix, distributed in two groups. Group A: was used titanium metal clip to the common bile duct ligation in three animals; group B: were ligated with 2-0 cotton thread in five animals. RESULTS: The ligation of the biliary ducts was performed successfully in all animals, with easy identification of the common bile duct by laparoscopy. There weren't difficulties in the procedures, mainly due to the increased surgical field provided by the excellent quality of light and image of the appliance. The clinical signs of jaundice were evident in the animals in seven days. In group A, two animals showed bile duct perforation near the clip, probably due to ischemic necrosis, progressing to peritonitis and death. In group B, five animals showed obstructive jaundice without any amendment. CONCLUSION: Under the conditions of this study, we therefore recommend the use of unabsorbed wires to experimental biliary obstruction, in order to avoid complications, such as ischemia and necrosis, followed by perforation of the wall of the bile ducts.


OBJETIVO: Induzir um quadro de icterícia obstrutiva extrahepática total em suínos, através da ligadura no ducto colédoco por meio de cirurgia videolaparoscópica. MÉTODOS: Oito suínos da raça Landrace, com 36 dias de idade, originários da mesma matriz, foram distribuídos em dois grupos. Grupo A: utilizou-se clipe metálico de titânio para ligadura do ducto colédoco em três animais; grupo B: foi feita a ligadura com fio de algodão 2-0 em cinco animais. RESULTADOS: A ligadura da via biliar principal foi realizada com sucesso em todos os animais, com fácil identificação do colédoco por videolaparoscopia. Não houve dificuldades nos procedimentos, principalmente devido ao aumento do campo cirúrgico proporcionado pela qualidade de luz e imagem do aparelho. Os sinais clínicos indicativos de icterícia foram evidentes nos animais em sete dias. No grupo A, dois animais apresentaram perfuração coledociana junto ao clipe por provável isquemia e necrose, evoluindo com coleperitônio e óbito. No grupo B, os cinco animais apresentaram quadro de icterícia obstrutiva sem qualquer alteração. CONCLUSÃO: Nas condições desse estudo, recomenda-se a utilização de fios inabsorvíveis para obstrução experimental das vias biliares, a fim de evitar complicações, como isquemia e necrose, seguida de perfuração da parede das vias biliares.

ABSTRACT

OBJETIVO: A colecistectomia laparoscópica é o tratamento de escolha para pacientes com colecistopatia calculosa, embora o manejo da coledocolitíase associada ainda permaneça assunto controverso. O presente estudo baseou-se na análise prospectiva de pacientes submetidos à colecistectomia eletiva com colangiografia peroperatória, pretendendo assim avaliar a positividade do exame contrastado das vias biliares em pacientes com colelitíase sem indicação para colangiografia. MÉTODOS: Foram incluídos, no estudo, 100 pacientes cujos parâmetros clínicos, laboratoriais e de imagem feitos até no máximo 10 dias antes da colecistectomia não apresentaram qualquer alteração no pré-operatório e, portanto, considerados pacientes insuspeitáveis para coledocolitíase. As colangiografias foram analisadas e examinadas pela equipe cirúrgica, pelo radiologista e pelos autores deste estudo. Os laudos foram comparados e correlacionados com achados clínicos e laboratoriais prévios dos pacientes. RESULTADOS: A incidência de coledocolitíase insuspeitável no pré-operatório foi de apenas um único caso entre 100 pacientes sem indicação para o exame (1% de positividade). CONCLUSÃO: Com base neste material, pode-se concluir que o emprego da colangiografia seletiva é segura e deve ser empregada no tratamento da colecistite calculosa.


OBJECTIVE: To evaluate the positivity of cholangiography in patients without formal indication of this exam undergoing elective cholecystectomy. METHODS: We included, in the study, 100 patients whose clinical, laboratory and imaging not older than 10 days before the operation showed no change and therefore kept us unsuspicious of choledocholithiasis. The cholangiographies were analyzed and examined by the surgical team, the radiologist and the authors. The reports were compared and correlated with patients' previous clinical and laboratory findings. RESULTS: The incidence of preoperatively unsuspected choledocholithiasis was only one case (1%). CONCLUSION: The use of selective cholangiography is safe and should be used in the treatment of calculous cholecystitis.

ABSTRACT

Objetivo: Utilizamos esta pesquisa para estudar e demonstrar que a esofagectomia subtotal através do acesso laparoscópico e transmediastinal para o preparo do estômago, dissecção do esôfago, abdominal e torácico, e cervicotomia esquerda para retirada da peça e anastomose esôfago-gástrica é facultativa e segura no tratamento do megaesôfago avançado. Métodos: Foram realizadas 60 esofagectomias transhiatais por laparoscopia de setembro de 1996 até dezembro de 2006 (10 casos com preservação dos nervos vagos). A idade média dos pacientes foi 56,4 anos (18 – 76) e antes da operação foram submetidos àsorologia para T. cruzi, esofagograma, endoscopia digestiva de alta resolução, eletromanometria, ultrassom de vesícula biliar e pHmetria de 24 horas, avaliação nutricional, fisioterapia respiratória e suporte nutricional através de sonda nasoenteral. As indicações para o tratamento cirúrgico foram: megaesôfago avançado, diagnosticado radiologicamente e manometricamente,recidiva de megaesôfago após operação envolvendo a junção esôfago-gástrica e associação com disfagia acentuada e/ouneoplasia. O acompanhamento foi de 6 a 118 meses. Resultados: Não houve mortalidade, o tempo médio das operações foi de 160 minutos (110 – 325) e houve melhora de todos os parâmetros avaliados. Doze dos 60 pacientes (20%) apresentaram complicações. Ocorreram oito casos de hemopneumotórax (13,34%), três casos de estase gástrica (5%), quatro casos de fístula cervical (6,67%) com resolução clínica e nove casos de disfonia (15%). Conclusão: Os resultados observados na esofagectomia transhiatal laparoscópica foram satisfatórios. Demonstraram que a técnica é segura e traz excelentes resultados pós-operatórios.


Objectives: We studied and demonstrated that the technique of subtotal esophagectomy, through laparoscopic and transmediastinalaccess, in order to prepare the stomach, to dissect the abdominal and thoracic esophagus, and to perform a left cervicotomy for esophageal removal and to proceed with an esophagogastric anastomosis is a good choice and it is a safe method for advanced megaesophagus treatment. Methods: Sixty transhiatal esophagectomies by laparoscopy were performed between September 1996 and December 2006, with preservation of the vagus nerve in the last ten cases. The mean age of the patients was 56.4 yearsold (18-76) and they were submitted to preoperative blood tests for T. Cruzi, esophagography, high-resolution digestive endoscopy,electromanometry, biliary ultrasound, and 24-hour ph-metry. Also a nutritional evaluation, respiratory physiotherapy and enteral nutritional support, using a nasoenteral tube were done. The indications for this surgery were radiologically and functionally advanced megaesophagus, recurrence of megaesophagus after surgery involving the esophageal junction and association of severe dysplasia and/or neoplasia. The follow-up period was from six to 118 months. Results: There was no mortality, the mean surgery time was 160 minutes (110 to 325), and improvement was noted in all evaluated parameters. Twelve of 60 (20%) patients presented with complications; eight cases had hemopneumothorax (13.33%); three cases had gastric stasis (5%); four cases had cervicalfistulae (6.67%), and resolution was achieved with non operative treatment; nine cases had dysphonia (15%). Conclusion: The results observed in laparoscopic transhiatal esophagectomy were encouraging. They demonstrated that this is a practical and safe technique with excellent postoperative results.

ABSTRACT

A ruptura é uma complicação rara dos aneurismas de artéria poplítea. Relatamos o caso de um paciente de 75 anos com dor intensa e edema no membro inferior direito, que era incapaz de deambular. A investigação diagnóstica através de exame físico, ultra-som, tomografia computadorizada e arteriografia revelaram a presença de um aneurisma de artéria poplítea roto. Foi realizada a revascularização. O paciente não apresentou intercorrências e evoluiu com recuperação total da função de seu membro.
