Outcomes of bariatric surgery in patients >70 years old

Abstract

Background: The aim of the present study was to report the outcomes of bariatric surgery in patients >70 years of age at a community hospital in the United States.

Methods: A retrospective review was performed of prospectively collected data from patients aged >70 years who had undergone bariatric surgery at a single institution from 2002 to 2008. The data analyzed included age, preoperative and postoperative weight and body mass index, postoperative complications, and co-morbidities.

Results: Of 42 patients aged >70 years who underwent bariatric surgery, 22 patients (52.4%) had undergone laparoscopic gastric banding, 12 patients (28.6%) laparoscopic sleeve gastrectomy, and 8 patients (19%) laparoscopic Roux-en-Y gastric bypass. The mean preoperative weight and body mass index was 127.4 ± 25.5 kg and 46.8 ± 9.3 kg/m(2), respectively. The mean postoperative weight and body mass index was 100.2 ± 17 kg and 35.5 ± 5.4 kg/m(2), respectively. The median length of follow-up was 12 months (range 1-66). The mean percentage of excess weight loss was 47.7% at 12 months, with 73.1% follow-up data. Complications included wound infections in 4 patients (9.5%), band removal in 3 patients (7.1%), anastomotic leak in 1 patient (2.3%), and megaesophagus in 1 patient (2.3%). No mortality occurred. The postoperative use of medications for hypertension, hyperlipidemia, diabetes mellitus, and degenerative joint disease were reduced by 56%, 54%, 53%, 66%, and 50%, respectively.

Conclusion: Bariatric surgery in carefully screened patients aged >70 years can be performed safely and can achieve modest improvement in co-morbidities.
