Weight loss and adherence to postoperative follow-up after vertical gastrectomy for obesity treatment

Purpose: To analyze the effectiveness of vertical gastrectomy in the treatment of obese patients, adherence to clinical follow-up and the influence of factors such as gender and age. Methods: This is a retrospective, observational and descriptive study, conducted with patients undergoing vertical gastrectomy, operated at Hospital Sao Domingos, between January 2016 and July 2018. Results: Most patients undergoing vertical gastrectomy were female (n = 193, 72.28%) and had a mean age of 37.11 +/- 8.96 years old. The loss of follow-up was 56.18%. Among adherent patients (n = 117; 43.82%), most patients were female (n = 89; 76.07%) and had a mean age of 37.92 +/- 9.85 years old. The mean body mass index (BMI) of the adherents in the preoperative was 37.85 +/- 3.72 kg/m(2). Both BMI and excess weight (EW) showed a statistically significant difference between pre- and postoperative period. Percentage of excess weight loss (% EWL) was satisfactory for 96.6% of adherent patients. Older patients had a statistically significant lower % EWL compared to the other groups. Conclusion: Vertical gastrectomy was effective in the treatment of obese patients, with significant weight loss.

Automated summary

The effectiveness of vertical gastrectomy in treating obese patients was analyzed in a retrospective observational study, showing significant weight loss and satisfactory excess weight loss percentage for adherent patients. Factors such as gender and age also influenced the outcomes, with older patients showing lower excess weight loss percentage compared to other groups.
