Background

Both obesity and life expectancy are increasing worldwide. The present study aimed to report the outcomes of bariatric surgery in patients≥65 years of age.

Methods

A retrospective review of prospectively collected data from patients aged ≥65 years who underwent LRYGP and LSG in our institute from 2006 to 2016. The data analyzed included age, preoperative and postoperative weight, body mass index, postoperative complications, and co-morbidities.

Results

A total of 47 patients≥65 years (66.5 ± 0.2 years) underwent bariatric surgery in our institute. Of these 47 patients, 21 patients (44.68%) had undergone LRYGP, 20 patients (42.55%) LSG, and six patients (12.76%) conversion of the gastric band (5 patients) and Maison (one patient) to LRYGP. The mean preoperative weight and body mass indexes were 109.06 ± 2.33kg and 40.93±0.74 kg/m2, respectively. The median length of follow-up was 12 months (range 1–48). The overall complication rate was 23.4%. No mortality occurred. For 21 patients, the mean percentage of excess weight loss and body mass index was 77.5± 6 % and 29.7±1 at 12 months. The resolution of diabetes mellitus, hypertension, and Obstructive sleep apnea syndrome was 70%, 57%, 75%, and 100 %, respectively.

Conclusions

Bariatric surgery in carefully screened patients ±65years can be performed safely and improve co-morbidities.
