A Propensity Score Cohort Study on the Long-Term Safety and Efficacy of Sleeve Gastrectomy in Patients Older Than Age 60

Abstract EN

Background.

Bariatric surgery (BS) in older obese subjects (>60 years of age) has risen in the past decade and will continue to rise in the coming years due to ageing of the population.

Aim.

To evaluate the short- (12 months) and long-term (60 months) results of laparoscopic sleeve gastroscopy (LSG) in patients older than age 60.

Methods.

We performed a retrospective review of patients prospectively included in a database from January 2007 to December 2013.

All patients >60 [older group (OG)] who had undergone LSG were included.

The control group (CG) included patients aged 50 to 59 years who had undergone LSG during the same period.

Results.

116 (8.4 % of total surgery) and 145 patients were included in the OG and CG, respectively.

BS in patients >60 years increased from 2.4% in 2003 to 14% in the last 2 years of the study.

After inverse probability of treatment weighting (IPTW) analysis, all absolute standardized differences were <0.15.

A 60-month follow-up was attained in 90% of patients in the OG and 74% in the CG.

There were no significant differences in postoperative complications between the two groups.

At 12 and 60 months after LSG, both groups achieved a similar body mass index.

There was no statistical difference in the percentage of resolution of type 2 diabetes, hypertension, dyslipidemia, and SAHS between the two groups.

In both groups, all the nutritional parameters evaluated remained within the normal range throughout the study.

Conclusions.

LSG provides acceptable outcomes and is safe in older adults indicating that age should not be a limitation to perform BS in this population.
