Abstract
Background
Biliopancreatic diversion with duodenal switch (BPD-DS) is one of the most effective surgical approaches for the treatment of severe obesity.
Objective
The objective of this study is to compare perioperative complications and long-term results of open BPD-DS in elderly versus younger patients.
Methods
All patients aged 60 years and above who underwent a primary open BPD-DS in our center were selected (n = 105). Patients were matched 1:1 for sex, BMI, the presence of type 2 diabetes (T2DM), and year of surgery with a group of younger patients (aged ≤55 years).
Results
The mean age of the patients was 62.3 ± 2.0 vs. 40.4 ± 7.0 years (p ≤ 0.0001). Initial BMI and prevalence of T2DM were similar in both groups, at 50.9 kg/m2 and 57 %, respectively. Mean operative time (178.6 ± 46.7 vs. 162.5 ± 39.9 min, p = 0.01), hospital stay (10.2 ± 8.3 vs. 6.3 ± 1.5 days, p = 0.0001), and blood loss (593 ± 484 vs. 474 ± 241 ml, p = 0.05) were significantly higher in elderly patients. No difference in 30-day mortality rate was observed (0.9 % in each group). There was no significant difference in major complication rate (16.2 vs. 8.6 %, p = 0.09). At a mean follow-up of 7.1 ± 4.1 years, excess weight loss (67.6 ± 19.2 vs. 72.7 ± 20.7 %, p = 0.06) and BMI (32.2 ± 5.7 vs. 30.8 ± 6.6 kg/m2, p = 0.15) were not significantly different. No significant difference was observed between the two groups for the resolution of T2DM (p = 0.53) and obstructive sleep apnea (p = 0.44).
Conclusions
Open BPD-DS is associated with similar long-term benefits in elderly and younger patients, in terms of weight loss and resolution or improvement of obesity-related comorbidities. Perioperative complications might be more frequent in the elderly population, but this was not associated with increased mortality.
