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 São Domingos,
between January 2016 and July 2018.
Results
Most patients undergoing vertical gastrectomy were female (n = 193, 72.28%)
and had a mean age of37.11 ± 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.
Conclusions
Vertical gastrectomy was effective in the treatment of obese patients, with
significant weight loss.
