Both groups were similar regarding gender, age, AC, BMI and number of patients, which offered greater credibility to the study. Surgical time was similar as well. Certainly, the increasing technical and technological evolution of video-surgery enabled procedures as agile as that of traditional laparotomy.A major limitation of most studies on the subject is the morbimortality approach, but not the efficacy of laparoscopy versus open-label procedures. There is no information assessment on other important results metrics, as return to normal activity or workThe present study evidenced the superiority of the laparoscopic access over the laparotomy in terms of length of hospital stay and time away from work activities.The laparoscopic Roux-en-Y, due to its minimally invasive nature, reduced postoperative hospitalization time by more than 30%. The Roux-en-Y laparotomy presented higher morbidity in the patients of our study, causing higher rates of complications, such as the occurrence of incisional hernia (17.5% in G1 vs 0% in G2), vomiting (25% in G1 vs 10% in G2), and superficial subcutaneous infection (17.5% in G1 vs 2.5% in G2).Reoch et al.On the other hand, incisional hernias may occur later at the trocar sites after laparoscopic bypass in obese patients. Rossi et al. analyzed 123 patients with BMI >35 kg/mSeveral studies indicated superiority of the laparoscopic route in relation to the open access regarding complications and length of hospital staySome other studies confirmed the cost-effectiveness of bariatric surgeryA possible limitation of this study would be the different proportion of comorbidities presented in both groups. In G1 there was a higher percentage of dyslipidemia. In G2, there was a higher prevalence of gastroesophageal reflux disease, osteoarthropathy, and stress urinary incontinence. The other diseases had similar prevalence between the groups.
