ROBOTIC VERSUS LAPAROSCOPIC ROUX-EN-Y-GASTRIC BYPASS: A RETROSPECTIVE STUDY IN A SINGLE CENTER.

BACKGROUND: Bariatric surgery is the best treatment option for patients with obesity. As a result of the advancement of technology, the robotic gastric bypass presents promising results, despite its still high costs. AIMS: The aim of this study was to compare patients submitted to a robotic versus a laparoscopic gastric bypass at a single center by a single surgeon. METHODS: This retrospective study collected data from the medical records of 221 patients (121 laparoscopic procedures versus 100 with daVinci platform). The variables analyzed were sex, age, body mass index, comorbidities, surgical time, length of stay, and complications. RESULTS: The mean surgical time for patients in the robotic group was shorter (102.41±39.44 min versus 113.86±39.03 min, p=0.018). The length of hospital stay in robotic patients was shorter (34.12±20.59 h versus 34.93±11.74 h, p=0.007). There were no serious complications. CONCLUSIONS: The group submitted to the robotic method had a shorter surgical time and a shorter hospital stay. No difference was found regarding strictures, bleeding, or leakage.

RESUMO RACIONAL: A cirurgia bariátrica é a melhor opção de tratamento para pacientes portadores de obesidade. Em decorrência do avanço da tecnologia, o bypass gástrico robótico apresenta resultados promissores, apesar de seus custos ainda elevados. OBJETIVOS: Comparar pacientes submetidos a bypass gástrico robótico versus laparoscópico em um único centro por um único cirurgião. MÉTODOS: Estudo retrospectivo com coleta de dados dos prontuários de 221 pacientes (121 procedimentos laparoscópicos vs 100 com plataforma daVinci). As variáveis analisadas foram sexo, idade, IMC, comorbidades, tempo cirúrgico, tempo de internação e complicações. RESULTADOS: O tempo cirúrgico médio dos pacientes do grupo robótico foi menor (102,41 ± 39,44 min. vs 113,86±39,03 min, p=0,018). O tempo de internação em pacientes robóticos foi menor (34,12±20,59 h vs 34,93±11,74 h, p=0,007). Não houve complicações graves. CONCLUSÕES: O grupo submetido ao método robótico apresentou menor tempo cirúrgico e menor tempo de internação. Nenhuma diferença foi encontrada na amostra em relação a estenoses, sangramento ou vazamento.
