ABSTRACT

Objective:

To compare the effect of age on clinical outcome of laparoscopic sleeve gastrectomy (LSG) in the obese patients.

Methods:

A total of 113 patients who underwent LSG due to obesity and metabolic disorders between 2013 and 2018 at Fudan University Pudong Hospital, and completed the scheduled follow-up (1, 3, 6, and 12 months after surgery) were included for the retrospective analysis. The patients were divided into three groups based upon pre-operative age, including 15 to 30 year-old group ( n=58), 31 to 45 year-old group ( n=32), and 45 to 65 year-old group ( n=23). The body weight related parameters, glycemic and metabolic related parameters, lipid panel as well as arterial blood pressure were compared at pre-operative baseline, 1, 3, 6, and 12 months after surgery. The quantitative data were analyzed by repeated measurement ANOVA, and the P value was corrected by Bonferroni method. And the categorical variables were analyzed by chi square test.

Results:

The preoperative baseline data showed that with the increase of age, the preoperative body mass index gradually decreased, which were (40.1±5.9) kg/m 2, (37.1±6.6) kg/m 2 and (35.3±7.4) kg/m 2 in 16 to 30, 31 to 45 and 46 to 65 year-old groups, respectively. Otherwise, other metabolic related parameters were comparable. At 12 months after LSG, there was no significant difference in the amount of weight loss among the groups, but the percentage of total weight loss (% TWL) and the percentage of total BMI loss (%TBMIL) decreased significantly with age increasing. The %TBMIL in 16 to 30, 31 to 45 and 46 to 65 year-old groups were 32.3±7.5%, 28.4±8.4% ( P<005 compared with 16 to 30 year-old group) and 25.7±8.2% (compared with 16 to 30 year-old group P<0.001), respectively. In the patients with preoperative HbA1c>7%, HbA1c reduction in the three groups at 12 months after operation were 3.20% (compared with 46-65 year-old group P<0.001), 2.64% (compared with 46-65 year-old group P<0.05) and 1.34%, respectively. The proportions of patients with HbA1c < 6.5% were 95.8%, 88.9% and 50.0%, respectively. LDL, triglyceride and arterial blood pressure in all groups decreased and HDL increased rapidly within 3 months after operation, but there was no significant difference among the three groups.

Conclusions:

The improvement of blood glucose metabolism and the remission rate of type 2 diabetes mellitus (T2DM) in the patients with older age were worse than those in the younger patients, and the T2DM in the younger patients tends to obtain better clinical remission after LSG; in terms of weight loss, with the increase of age, %TWL and %TBMIL also showed a decreasing trend; however, the improvement of blood lipid and blood pressure after LSG was not affected by the factor of age. This study implies that patients who meet the indications of metabolic and bariatric surgery should be suggested to receive surgical treatment early in order to achieve better clinical outcomes.
