The advancement of minimal invasive techniques pushed the age limit for patients qualified for bariatric surgery.

The aim of the study was to evaluate the safety and effectiveness of laparoscopic sleeve gastrectomy (LSG) in a cohort of patients aged 60 years or more, compared with a group of matched controls below 40 years old.

The medical records of 856 patients were analyzed. Patients aged 60 years or older were identified as cases. Those below 40 years were identified as the controls. Cases were closely matched (1:1) with the controls by body mass index (BMI) (± 1 kg/m2) and presence or absence of hypertension and diabetes mellitus.

A 34 matched pairs were included in the study. There was no significant difference in the median operation length. No conversion from laparoscopic to open surgery was needed. The hospital length of stay was significantly longer in the study group (4.5 ± 1.9 vs 3.9 ± 1.5 days, p = 0.047). The complication, 30-day reoperation, and 30-day reoperation rates were comparable in both groups. There were no 30-day readmissions nor 30-day mortality. ΔBMI after 12 months was significantly lower in the study group (13.56 ± 6.05 vs 10.3 ± 4.89, p = 0.008) as well as %EBMIL (50.71 ± 25.94 vs 64.20 ± 23.29, p = 0.015).

The study suggests that LSG is a safe method of bariatric treatment in patients aged above 60 years. Even though weight loss may be lesser than in younger patients, it can still be considered satisfactory.
