RESUMO Objetivo: relatar uma série de casos de cirurgia bariátrica robótica no tratamento da obesidade no Brasil. Métodos: foram avaliados pacientes submetidos à cirurgia bariátrica robótica no Instituto Garrido, e realizada comparação com grupo submetido à cirurgia laparoscópica convencional. Resultados: foram analisados 45 pacientes, com média de idade de 39,44 anos, sendo 34 do sexo feminino, com média de IMC inicial de 41,26Kg/m2. Dentre as cirurgias realizadas, 91,11% foram bypass gástrico em Y de Roux, enquanto 8,89% foram do tipo gastrectomia vertical. A média de tempo total de cirurgia foi de 158 (±56,54) minutos, com tempo médio de docking de 7,93 (±3,9) minutos e tempo de console 113,0 (±41,4) minutos. A média de dor apresentada na recuperação pós-anestésica foi de 2,61 (±3,30) pontos, em escala de 0 a 10, com quatro pacientes apresentando sinais leves de náusea, respondendo bem ao tratamento medicamentoso. Somente um paciente necessitou internação em UTI por um período de dois dias após a cirurgia, devido à cardiopatia prévia. Em dois casos ocorreram hérnia incisional em sítio de trocater, tratados cirurgicamente, sem posteriores complicações. Na comparação entre os grupos de cirurgia robótica versus laparoscópica, foram selecionados 45 pacientes para cada grupo. O tempo operatório foi significativamente mais longo na via robótica, sendo a maior parte das outras variáveis equivalentes, inclusive controle pós-operatório de comorbidades. Conclusão: a cirurgia bariátrica robótica é um procedimento seguro, com resultados comparáveis à cirurgia laparoscópica.

ABSTRACT Objective: to report a series of cases of robotic bariatric surgery in the treatment of obesity in Brazil. Methods: we evaluated patients undergoing robotic bariatric surgery at the Garrido Institute and compared them with a group submitted to conventional laparoscopic surgery. Results: we analyzed 45 patients, with a mean age of 39.44 years, of which 34 were female, with an initial mean BMI of 41.26kg/m2. Among the procedures performed, 91.11% were Roux-en-Y gastric bypass, while 8.89% were sleeve gastrectomy. The mean total surgery time was 158 (±56.54) minutes, with mean docking time of 7.93 (±3.9) minutes, and console time 113.0 (±41.4) minutes. The average pain presented in the post anesthetic recovery was 2.61 (±3.30) points on a scale of 0 to 10; four patients presented with mild signs of nausea, responding well to drug treatment. Only one patient needed ICU admission for a period of two days after surgery due to previous cardiopathy. In two cases, there was an incisional hernia at the trocar site, which were surgically treated without further complications. In the comparison between robotic versus laparoscopic surgery groups, 45 patients were selected for each group. Operative time was significantly longer in the robotic surgery group, with most other variables being equivalent, including postoperative control of comorbidities. Conclusion: robotic bariatric surgery is a safe procedure, with results comparable to laparoscopic surgery.

OBJECTIVE: To assess the postural control and flexibility of obese subjects before and both six and 12 months after bariatric surgery. To verify whether postural control is related to flexibility following weight reductions resulting from bariatric surgery. METHODS: The sample consisted of 16 subjects who had undergone bariatric surgery. All assessments were performed before and six and 12 months after bariatric surgery. Postural balance was assessed using an Accusuway¯ portable force platform, and flexibility was assessed using a standard chair sit and reach test (Wells’ chair). RESULTS: With the force platform, no differences were observed in the displacement area or velocity from the center of pressure in the mediolateral and anteroposterior directions. The displacement speed from the center of pressure was decreased at the six month after the surgery; however, unchanged from baseline at 12 months post-surgery. Flexibility increased over time according to the three measurements tested. CONCLUSIONS: Static postural balance did not change. The velocity of postural adjustment responses were increased at six months after surgery. Therefore, weight loss promotes increased flexibility. Yet, improvements in flexibility are not related to improvements in balance.
