ABSTRACT Purpose: Simultaneous pancreas-kidney transplantation (SPKT) brings several benefits for insulin-dependent type-1 diabetic patients associated with end-stage renal disease (ESRD). However, data on psychological outcomes for the waiting list and the transplanted patients are still lacking. Methods: Using the psychological Beck inventories of anxiety (BAI) and depression (BDI), 39 patients on the waiting list were compared to 88 post-transplanted patients who had undergone SPKT. Results: Significant differences were found regarding depression (p = 0.003) but not anxiety (p = 0.161), being the pretransplant patients more vulnerable to psychological disorders. Remarkable differences were observed relative to the feeling of punishment (p < 0.001) and suicidal thoughts (p = 0.008) between the groups. It was observed that patients who waited a longer period for the transplant showed more post-transplant anxiety symptoms due to the long treatment burden (p = 0.002). Conclusions: These results demonstrated the positive impact of SPKT on psychological aspects related to depression when comparing the groups. The high number of stressors in the pretransplant stage impacts more severely the psychosocial condition of the patient.

Objective: Parkinson’s disease (PD) is often accompanied by stigma, which could contribute to a worse prognosis. The objective of this study is to identify the variables associated with stigma in PD patients who are candidates for deep brain stimulation (DBS). Methods: We investigated sociodemographic and clinical variables associated with stigma in a sample of 54 PD patients indicated for DBS. The independent variables were motor symptoms assessed by the Movement Disorder Society‐sponsored revision of the Unified Parkinson Disease Rating Scale (MDS-UPDRS III), depressive symptoms measured by the Hospital Anxiety and Depression Scale, age, disease duration and the presence of a general medical condition. The Mobility, Activities of daily living and Emotional well-being domains of the 39-item Parkinson’s Disease Questionnaire (PDQ-39) were also investigated as independent variables, and the Stigma domain of the PDQ-39 scale was considered the outcome variable. Results: After multiple linear regression analysis, activities of daily living remained associated with the Stigma domain (B = 0.42 [95%CI 0.003-0.83], p = 0.048). The full model accounted for 15% of the variance in the Stigma domain (p = 0.03). Conclusions: Although causal assumptions are not appropriate for cross-sectional studies, the results suggest that ADL difficulties could contribute to greater stigma in PD patients with refractory motor symptoms who are candidates for DBS.

Abstract Purpose: The benefits of laparoscopic approaches to treat colorectal cancer (CRC) and colorectal liver metastases (CRLM) separately are well established. However, there is no consensus about the optimal timing to approach the primary tumor and CRLM, whether simultaneously or staged. The objective of this review with practical reports is to discuss technical aspects required for patient selection to perform simultaneous laparoscopic approaches for CRC and CRLM. Methods: Literature review of oncological factors associated with patient selection for surgical treatment of CRLM and the use of laparoscopy in those cases, and report of technical aspects for simultaneous CRC and CRLM approaches. Results: Simultaneous laparoscopic resection has been successful in many series of selected patients, although it seems to be safer to perform minor and major liver resection with non-extended colorectal resections, and to avoid two high-risk procedures at the same time. Conclusions: Simultaneous CRC and CRLM resections seem to be safe when patients are carefully selected, also considering the risk of recurrence concerning oncologic outcomes. The pre-planning of simultaneous resection is mandatory to plan trocar positioning, procedure sequencing, and patient position.

RESUMO Racional: Carcinoma incidental da vesícula biliar é definido como uma neoplasia descoberta por exame histológico após colecistectomia videolaparoscópica. É potencialmente uma doença curável. Entretanto algumas questões relacionadas ao seu manuseio permanecem controversas e uma estratégia definida está associada com melhor prognóstico. Objetivo: Desenvolver o primeiro consenso baseado em evidências para o manuseio de pacientes com carcinoma incidental da vesícula biliar no Brasil. Métodos: Dezesseis questões foram selecionadas e para responder as questões e 36 membros das sociedades brasileiras e internacionais foram incluídos. As recomendações foram baseadas em evidências da literatura atual. Um relatório final foi enviado para os membros do painel para avaliação de concordância. Resultados: Avaliação intraoperatória da peça cirúrgica, uso de bolsas para retirar a peça cirúrgica e exame histopatológico de rotina, foram recomendados. Avaliação pré-operatória completa é necessária e deve ser realizada assim que o estadiamento final esteja disponível. Avaliação da margem do ducto cístico e biópsia de rotina do linfonodo 16b1 são recomendadas. Quimioterapia deve ser considerada e quimioradioterapia indicada se a margem cirúrgica microscópica seja positiva. Os portais devem ser ressecados excepcionalmente. O estadiamento laparoscópico antes da operação é recomendado, mas o tratamento radical por abordagem minimamente invasiva deve ser realizado apenas em centros especializados em cirurgia hepatopancreatobiliar minimamente invasiva. A extensão da ressecção hepática é aceitável até que seja alcançada a ressecção R0. A linfadenectomia padrão é indicada para tumores iguais ou superiores a T2, mas a ressecção da via biliar não é recomendada de rotina. Conclusões: Recomendações seguras foram preparadas para carcinoma incidental da vesícula biliar, destacando os mais frequentes tópicos do trabalho diário do cirurgião do aparelho digestivo e hepatopancreatobiliar.

ABSTRACT Background: Incidental gallbladder cancer is defined as a cancer discovered by histological examination after cholecystectomy. It is a potentially curable disease. However, some questions related to their management remain controversial and a defined strategy is associated with better prognosis. Aim: To develop the first evidence-based consensus for management of patients with incidental gallbladder cancer in Brazil. Methods: Sixteen questions were selected, and 36 Brazilian and International members were included to the answer them. The statements were based on current evident literature. The final report was sent to the members of the panel for agreement assessment. Results: Intraoperative evaluation of the specimen, use of retrieval bags and routine histopathology is recommended. Complete preoperative evaluation is necessary and the reoperation should be performed once final staging is available. Evaluation of the cystic duct margin and routine 16b1 lymph node biopsy is recommended. Chemotherapy should be considered and chemoradiation therapy if microscopically positive surgical margins. Port site should be resected exceptionally. Staging laparoscopy before reoperation is recommended, but minimally invasive radical approach only in specialized minimally invasive hepatopancreatobiliary centers. The extent of liver resection is acceptable if R0 resection is achieved. Standard lymph node dissection is required for T2 tumors and above, but common bile duct resection is not recommended routinely. Conclusions: It was possible to prepare safe recommendations as guidance for incidental gallbladder carcinoma, addressing the most frequent topics of everyday work of digestive and general surgeons.

Abstract Purpose: To compare four types of mesh regarding visceral adhesions, inflammatory response and incorporation. Methods: Sixty Wistar rats were divided into four groups, with different meshes implanted intraperitoneally: polytetrafluoroethylene (ePTFE group); polypropylene with polydioxanone and oxidized cellulose (PCD); polypropylene (PM) and polypropylene with silicone (PMS). The variables analyzed were: area covered by adhesions, incorporation of the mesh and inflammatory reaction (evaluated histologically and by COX2 immunochemistry). Results: The PMS group had the lowest adhesion area (63.1%) and grade 1 adhesions. The ePTFE and PM groups presented almost the total area of their surface covered by adherences (99.8% and 97.7% respectively) The group ePTFE had the highest percentage of area without incorporation (42%; p <0.001) with no difference between the other meshes. The PMS group had the best incorporation rate. And the histological analysis revealed that the inflammation scores were significantly different. Conclusions: The PM mesh had higher density of adherences, larger area of adherences, adherences to organs and percentage of incorporation. ePTFE had the higher area of adherences and lower incorporation. The PMS mesh performed best in the inflammation score, had a higher incorporation and lower area of adherences, and it was considered the best type of mesh.

RESUMO Racional: Litíase intra-hepática primária é definida quando os cálculos são formados dentro do fígado, podendo estar associada à dilatação local e estenosa da via biliar. A ressecção hepática é considerada o procedimento ideal. Objetivo: Avaliar os resultados da ressecção hepática no tratamento da litíase intra-hepática não oriental. Métodos: Cinquenta e um pacientes com hepatolitíase benigna não oriental sintomática foram submetidos à ressecção hepática em seis instituições no Brazil. Os dados demográficos, sintomas clínicos, classificação, diagnóstico, tratamento e evolução pós-operatória foram analisados. Resultados: Dos 51 pacientes havia 28 homens (54,9%), e a idade média era de 49,3 anos. História de colangite foi observada em 15 pacientes (29,4%). Os tipos de litíase observados foram tipo I em 39 (76,5%) e tipo IIb em 12 (23,5%), com o tipo adicional Ea em seis pacientes (11,8%). Os testes de função hepática estavam normais em 42 (82,4%) e atrofia segmentar foi observada em 12 (23,5%). O tratamento incluiu setorectomia lateral esquerda em 24 (47,1%), hepatectomia esquerda em 14 (27,5%) e hepatectomia direita em oito pacientes (15,7%). A hepaticojejunostomia esteve associada ao procedimento inicial em quatro (7,8%). Hepatectomia por videolaparoscopia foi realizada em oito (15,7%). Complicações pós-operatórias foram observadas em 20 pacientes (39,2%) e não houve mortalidade. Conclusão: Ressecção hepática na hepatolitíase é o procedimento ideal, pois remove os cálculos, a estenose, o parênquima atrofiado e minimiza os riscos para colangiocarcinoma.

ABSTRACT Background: Primary intrahepatic lithiasis is defined when the stones are formed in the liver and associated with local dilatation and biliary stricture. Liver resection is the ideal procedure. Aim: To evaluate the results of liver resection in the treatment of non-oriental intrahepatic lithiasis. Methods: Fifty-one patients with symptomatic benign non-oriental hepatolithiasis underwent surgical resection in six institutions in Brazil. Demography data, clinical symptoms, classification, diagnosis, management and postoperative course were analyzed. Results: Of the 51 patients, 28 were male (54.9%), with a mean age of 49.3 years. History of cholangitis was observed in 15 (29.4%). The types of intrahepatic lithiasis were type I in 39 (76.5%) and type IIb in 12 (23.5%), with additional type Ea in six (11.8%). Liver function test were normal in 42 patients (82.4%). Segmental atrophy was observed in 12 (23.5%). Treatments included left lateral sectionectomy in 24 (47.1%), left hepatectomy in 14 (27.5%) and right hepatectomy in eight (15.7%), with associated hepaticojejunostomy in four (7.8%). Laparoscopic liver resection was performed in eight (15.7%). Postoperative complications were observed in 20 (39.2%) with no mortality. Conclusion: Liver resection in patients with hepatolithiasis is the ideal procedure as it removes stones, stricture, atrophic parenchyma, and minimizes the risk of cholangiocarcinoma.

RESUMO Objetivo: avaliar o impacto financeiro das complicações pós-operatórias no transplante simultâneo pâncreas-rim durante a internação hospitalar. Métodos: estudo retrospectivo dos dados da internação hospitalar dos pacientes submetidos consecutivamente ao transplante simultâneo pâncreas-rim no período de janeiro de 2008 a dezembro de 2014 no Hospital do Rim/Fundação Oswaldo Ramos. As principais variáveis estudadas foram a reoperação, pancreatectomia do enxerto, óbito, complicações pós-operatórias (cirúrgicas, infecciosas, clínicas e imunológicas) e os dados financeiros da internação para o transplante. Resultados: a amostra foi composta de 179 pacientes transplantados. As características dos doadores e receptores foram semelhantes nos pacientes com e sem complicações. Na análise dos dados, 58,7% dos pacientes apresentaram alguma complicação pós-operatória, 21,8% necessitaram de reoperação, 12,3%, de pancreatectomia do enxerto e 8,4% evoluíram para o óbito. A necessidade de reoperação ou pancreatectomia do enxerto aumentou o custo da internação em 53,3% e 78,57%, respectivamente. A presença de complicação pós-operatória aumentou significativamente o custo. Entretanto, a presença de óbito, hérnia interna, infarto agudo do miocárdio, acidente vascular cerebral e disfunção do enxerto pancreático não apresentaram significância estatística no custo, cuja média foi de US$ 18,516.02. Conclusão: complicações pós-operatórias, reoperação e pancreatectomia do enxerto aumentaram significativamente o custo médio da internação hospitalar do SPK, assim como as complicações cirúrgicas, infecciosas, clínicas e imunológicas. No entanto, o óbito durante a internação, a hérnia interna, o infarto agudo do miocárdio, o acidente vascular cerebral e a disfunção do enxerto pancreático não interferiram estatisticamente neste custo.

ABSTRACT Objective: considering simultaneous pancreas-kidney transplantation cases, to evaluate the financial impact of postoperative complications on hospitalization cost. Methods: a retrospective study of hospitalization data from patients consecutively submitted to simultaneous pancreas-kidney transplantation (SPKT), from January 2008 to December 2014, at Kidney Hospital/Oswaldo Ramos Foundation (Sao Paulo, Brazil). The main studied variables were reoperation, graft pancreatectomy, death, postoperative complications (surgical, infectious, clinical, and immunological ones), and hospitalization financial data for transplantation. Results: the sample was composed of 179 transplanted patients. The characteristics of donors and recipients were similar in patients with and without complications. In data analysis, 58.7% of the patients presented some postoperative complication, 21.8% required reoperation, 12.3% demanded graft pancreatectomy, and 8.4% died. The need for reoperation or graft pancreatectomy increased hospitalization cost by 53.3% and 78.57%, respectively. The presence of postoperative complications significantly increased hospitalization cost. However, the presence of death, internal hernia, acute myocardial infarction, stroke, and pancreatic graft dysfunction did not present statistical significance in hospitalization cost (in average US$ 18,516.02). Conclusion: considering patients who underwent SPKT, postoperative complications, reoperation, and graft pancreatectomy, as well as surgical, infectious, clinical, and immunological complications, significantly increased the mean cost of hospitalization. However, death, internal hernia, acute myocardial infarction, stroke, and pancreatic graft dysfunction did not statistically interfere in hospitalization cost.

Abstract Purpose: To analyze the use of this sponge in pediatric patients undergoing split-liver transplantation. Methods: Retrospective study, including 35 pediatric patients undergoing split-liver transplantation, divided into two groups according to the use of the sponge: 18 patients in Group A (no sponge) and 17 in Group B (with sponge). Results: The characteristics of recipients and donors were similar. We observed greater number of reoperation due to bleeding in the wound area in Group A (10 patients - 55.5%) than in Group B (3 patients - 17.6%); p = 0.035. The median volume of red blood cells transfused in Group A was significantly higher (73.4 ± 102.38 mL/kg) than that in Group B (35.1 ± 41.67 mL/kg); p = 0.048. Regarding bile leak there was no statistical difference. Conclusion: The use of the human fibrinogen and thrombin sponge, required lower volume of red blood cell transfusion and presented lower reoperation rates due to bleeding in the wound area.

Abstract Purpose: To evaluate the effects of mesenchymal stem cells on liver regeneration in rats following a 70% hepatectomy. Methods: Forty rats were subjected to 70% hepatectomy and then ~106 mesenchymal stem cells (test group), or saline solution (control group), were infused into their livers via the portal vein. Each treatment group was divided into early and late subgroups (euthanized 3 d and 5 d following the operation, respectively). Group comparisons of Albumin, aminotransaminases (AST, ALT), and Alcaline Phosphatase (AP) levels, proliferative index (ki-67+ straining), and mitotic cell counts were conducted. Results: No significant differences in liver regeneration rate, number of mitoses, proliferative index, or serum levels of albumin, AST, or AP were observed. ALT levels were higher in the test group than in the control group (p<.05). Conclusions: Mesenchymal stem-cell therapy did not improve liver regeneration rate 3 d or 5 d after 70% hepatectomy in rats. Likewise, the therapy appeared not to affect liver function, proliferative index, or number of mitoses significantly.

RESUMO Racional: Estratégia cirúrgica para aumentar o número de transplantes hepáticos na população pediátrica é a transecção hepática ex-situ (redução ou split). No entanto, ela está associada com complicações, tais como hemorragia e fístulas. A esponja de fibrinogênio e trombina humana é útil para melhorar a hemostasia nas operações hepáticas. Objetivo: Comparar transplantes hepáticos pediátricos com transecção hepática ex-situ (redução ou split) com ou sem a esponja de fibrinogênio e trombina humana. Métodos: Foi realizada análise prospectiva de 21 pacientes submetidos ao transplante de fígado com transecção hepática ex-situ com a aplicação da esponja de fibrinogênio e trombina humana na área cruenta (grupo A) e análise retrospectiva de 59 pacientes sem a esponja (grupo B). Resultados: As características dos receptores e doadores eram semelhantes. Observou-se menor número de reoperações devido à hemorragia na área da cruenta no grupo A (14,2%) em comparação com o grupo B (41,7%, p=0,029). Não houve diferença em relação à fístula biliar (grupo A: 17,6%, grupo B: 5,1%, p=0,14). Conclusão: Houve menor número de reoperações por sangramento da área cruenta do enxerto hepático quando a esponja de fibrinogênio e trombina humana foi utilizada.

ABSTRACT Background: Surgical strategy to increase the number of liver transplants in the pediatric population is the ex-situ liver transection (reduction or split). However, it is associated with complications such as hemorrhage and leaks. The human fibrinogen and thrombin sponge is useful for improving hemostasis in liver surgery. Aim: Compare pediatric liver transplants with ex-situ liver transection (reduction or split) with or without the human fibrinogen and thrombin sponge. Methods: Was performed a prospective analysis of 21 patients submitted to liver transplantation with ex-situ liver transection with the application of the human fibrinogen and thrombin sponge in the wound area (group A) and retrospective analysis of 59 patients without the sponge (group B). Results: The characteristics of recipients and donors were similar. There were fewer reoperations due to bleeding in the wound area in group A (14.2%) compared to group B (41.7%, p=0.029). There was no difference in relation to the biliary leak (group A: 17.6%, group B: 5.1%, p=0.14). Conclusion: There was a lower number of reoperations due to bleeding of the wound area of the hepatic graft when the human fibrinogen and thrombin sponge were used.

RESUMO Neste último módulo do consenso, abordou-se alguns temas controversos. O primeiro tópico discutido foi o manejo da doença após progressão na primeira linha de quimioterapia, com foco em se ainda haveria indicação cirúrgica neste cenário. A seguir, o painel debruçou-se sobre as situações de ressecção da doença hepática na presença de doença extra-hepática, assim como, qual a melhor sequência de tratamento. O tratamento de conversão para doença inicialmente irressecável também foi abordado neste módulo, incluindo as importantes definições de quando se pode esperar que a doença se torne ressecável e quais esquemas terapêuticos seriam mais efetivos à luz dos conhecimentos atuais sobre a biologia tumoral e taxas de resposta objetiva. Por último, o tratamento da doença não passível de ressecção foi discutida, focando-se nos melhores esquemas a serem empregados e seu sequenciamento, bem como o papel da quimioembolização no manejo destes pacientes.

ABSTRACT In the last module of this consensus, controversial topics were discussed. Management of the disease after progression during first line chemotherapy was the first discussion. Next, the benefits of liver resection in the presence of extra-hepatic disease were debated, as soon as, the best sequence of treatment. Conversion chemotherapy in the presence of unresectable liver disease was also discussed in this module. Lastly, the approach to the unresectable disease was also discussed, focusing in the best chemotherapy regimens and hole of chemo-embolization.

RESUMO Racional: A neoplasia sólida pseudopapilar é tumor raro de pâncreas de tratamento cirúrgico. No entanto, sua causa ainda gera discussões. Objetivo: Analisar os dados clínicos, do diagnóstico e do tratamento da dessa neoplasia. Métodos: Estudo retrospectivo com dados médicos de pacientes tratados entre janeiro de 1997 a julho de 2015. Resultados: Foram identificados 17 casos. A maioria era de mulheres (94,11%) e a média de idade foi de 32,88 anos. A principal queixa era massa abdominal (47,05%). A localização mais frequente era no corpo/cauda do pâncreas (72,22%) e a operação mais realizada foi a pancreatectomia corpocaudal com esplenectomia (64,70%). Nenhum caso apresentou metástase no momento do diagnóstico. Operação conservadora de parênquima pancreático foi realizada em apenas três casos. A taxa de complicações no pós-operatório foi de 35,29% e a principal complicação foi fístula pancreática (29,41%). Nenhum paciente realizou adjuvância no seguimento. Conclusões: A mais comum apresentação clínica da neoplasia sólida pseudopapilar é de massa abdominal. Ela é de tratamento cirúrgico e pancreatectomia corpocaudal com esplenectomia é o procedimento mais realizado para seu tratamento.

ABSTRACT Background: The solid pseudopapillary neoplasm is a rare tumor of the pancreas. However, it´s etiology still maintain discussions. Aim: To analyze it´s clinical data, diagnosis and treatment. Methods: A retrospective study of medical records of all patients treated from January 1997 until July 2015. Results: Were identified 17 cases. Most patients were women (94.11%) and the average age was 32.88 years. The main complaint was abdominal mass (47.05%). The most frequent location was in the body/tail of the pancreas (72.22%) and the most frequently performed surgery was distal pancreatectomy with splenectomy (64.70%). No patient had metastases at diagnosis. Conservative surgery for pancreatic parenchyma was performed in only three cases. The rate of complications in the postoperative period was 35.29% and the main complication was pancreatic fistula (29.41%). No patient underwent adjuvant treatment.

PURPOSE : To evaluate and compare clinical and inflammatory responses to the surgical trauma caused by cholecystectomy via several access approaches: single-port umbilical incision (SILS), transvaginal natural orifice transluminal endoscopic surgery (NOTES), laparoscopy, and Laparotomy. METHODS : Twenty-eight female pigs were equally divided into four groups and submitted to cholecystectomy by single-port umbilical incision, transvaginal NOTES, laparoscopy, or Laparotomy. An additional five animals served as controls (sham group). Animals were monitored perioperatively regarding anesthesia and surgical procedure times, as well as for the presence of complications. Postoperatively, they were evaluated regarding time to ambulation and feeding, and the presence of clinical events. Procalcitonin, C-reactive protein (CRP), and AQUI feron-gamma (IFN-γ) measurements were performed before surgery and immediately, two days, and seven days after surgery. Animals were sacrificed and necropsied at seven days after surgery. RESULTS : All procedures were successfully performed as proposed in each group. Only minor complications, such as gallbladder perforation and bleeding from the liver bed, were observed during surgery in all groups. The vaginal NOTES group showed higher anesthesia and surgical procedure times compared to the other groups (p<0.001). No other between-group differences in perioperative or postoperative times, clinical evolution, or serum inflammatory markers were observed. Only adhesions were found on necropsy, with no differences between groups. CONCLUSION: The single-port umbilical and transvaginal NOTES access approaches were feasible and safe compared to laparoscopic and laparotomy for cholecystectomy.

PURPOSE:To evaluate the protective effects of chilling the bile ducts with cold (5°C) 5% glucose solution (GS) during radiofrequency (RF) administration.METHODS:Twenty male pigs (3 mos. old; 25-30 kg) were subjected to RF delivery with chilling (experimental group, N=10) or without chilling (control group, N=10). Half of the animals in each group were euthanized immediately after the operation, and half were euthanized one week later. The following histological variables in relation to the bile ducts were evaluated by a pathologist (blind examiner): degenerative changes to the epithelium; epithelial necrosis; ulceration, regenerative changes of the epithelium; polymorphonuclear neutrophil infiltration; and thermal effects.RESULTS: The experimental group (88 bile ducts examined) showed reduced thermal damage relative to the control group (86 bile ducts examined) as demonstrated by significant differences in the following histopathological parameters: epithelial detachment of biliary epithelium (84.1% vs. 59.3%; p<0.006); elongation/palisade arrangement of nuclei (65.1% vs. 87.5%; p<0.001); pseudo-goblet cells (32.9% vs. 56.8%; p<0.001).CONCLUSION: Infusion of 5% glucose solution (5°C) has a protective effect on bile ducts subjected to heat (95-110°C, 12 min) from radiofrequency thermal ablation device.

RACIONAL: A utilização da videolaparoscopia para o tratamento das neoplasia gástricas sofreu certa resistência entre os cirurgiões ao redor do mundo, ganhando força na década passada. Porém, sua segurança oncológica e viabilidade técnica continuam controversas. OBJETIVO: Demonstrar os resultados do ponto de vista clínico e anatomopatológico na avaliação comparativa entre o tratamento cirúrgico videolaparoscópico e laparotômico da gastrectomia total com linfadenectomia a D2, ressecção R0. MÉTODOS: Estudo retrospectivo dos dados dos prontuários dos pacientes submetidos à gastrectomia total com lindadenectomia a D2, em uma única instituição. Dos 111 prontuários, 64 (57,7%) foram submetidos à gastrectomia laparotômica e 47 (42,3%) à gastrectomia totalmente vídeolaparoscópica. Foram avaliadas variáveis relacionadas ao ato cirúrgico, a evolução pós-operatória e a achados anatomopatológicos. RESULTADOS: A técnica videolaparoscópica demonstrou tempo cirúrgico menor e período para re-introdução alimentar oral e enteral mais precoce que a operação laparotômica. Quanto ao número de linfonodos dissecados, houve diferença significante a favor da laparotômica (p=0,014); porém, a média de linfonodos dissecados em ambos os grupos ultrapassou os 25 preconizados pela JAGC. Não foi encontrada diferença significante entre os grupos estudados no que diz respeito à idade, gênero, ASA, tipo de operação, necessidade de hemotransfusão, estadiamento, classificação de Bormann, grau de diferenciação, comprometimento de margens, complicações e óbito. CONCLUSÕES: A gastrectomia total com linfadenectomia a D2 realizada por videolaparoscopia apresenta os mesmos benefícios conhecidos da cirurgia laparotômica e com as vantagens já estabelecidas da cirurgia minimamente invasiva. Ela apresentou menor tempo cirúrgico, menor tempo para a re-introdução das dietas oral e enteral e tempo de alta menor em relação à laparotômica, sem aumentar as complicações pós-operatórias.

BACKGROUND: The use of laparoscopy for the treatment of gastric cancer suffered some resistance among surgeons around the world, gaining strength in the past decade. However, its oncological safety and technical feasibility remain controversial. AIM: To describe the results from the clinical and anatomopathological point of view in the comparative evaluation between the surgical videolaparoscopic and laparotomic treatments of total gastrectomy with linphadenectomy at D2, resection R0. METHOD: Retrospective analyses and comparison data from patients submitted to total gastrectomy with D2 linphadenectomy at a sole institution. The data of 111 patients showed that 64 (57,7%) have been submitted to laparotomic gastrectomy and 47 (42,3%) to gastrectomy entirely performed through videolaparoscopy. All variables related to the surgery, post-operative follow-up and anatomopathologic findings have been evaluated. RESULTS: Among the studied variables, videolaparoscopy has shown a shorter surgical time and a more premature period for the introduction of oral and enteral nourishment than the open surgery. As to the amount of dissected limph nodes, there has been a significant difference towards laparotomy with p=0,014, but the average dissected limph nodes in both groups exceed 25 nodes as recommended by the JAGC. Was not found a significant difference between the studied groups as to age, ASA, type of surgery, need for blood transfusion, stage of the disease, Bormann classification, degree of differentiation, damage of the margins, further complications and death. CONCLUSION: The total gastrectomy with D2 lymphadenectomy performed by laparoscopy presented the same benefits known of laparotomy and with the advantages already established of minimally invasive surgery. It was done with less surgical time, less time for re-introduction of the oral and enteral diets and lower hospitalization time compared to laparotomy, without increasing postoperative complications.
