Abstract
The effect of hyperinsulinemia on short-term outcomes after laparoscopic sleeve gastrectomy (LSG) in patients with obesity combined with insulin resistance is unclear. This was a retrospective analysis of patients who underwent LSG at our center between January 1, 2020, and December 31, 2021. Patients were divided into hyperinsulinemia (HINS) and nonhyperinsulinemia (NHINS) groups based on fasting insulin levels. The primary endpoint was weight change. Metabolic disease outcomes, postoperative complications, and quality of life score changes were secondary endpoints. A total of 92 patients were included in this study, with 59 in the HINS group and 33 in the NHINS group. At 6 months postoperatively, the median (P25, P75) %EWL was 76.01 (64.40, 86.99)% in the HINS group and 92.02 (86.78, 100.88)% in the NHINS group (P<0.001). The mean %TWL (SD) was 23.26 (7.14)% in the HINS group and 26.80 (6.55)% in the NHINS group (P=0.021). The remission of dyslipidemia and hypertension in the NHINS group and the HINS group were not significantly different (P>0.05 for all). The differences in QOL between groups were not statistically significant (P=0.788). In terms of postoperative complications, there was no statistically significant difference between the groups (P>0.05 for all). HINS negatively influences weight change in patients with obesity and insulin resistance, and the NHINS group had better postoperative weight loss. In terms of hypertension, dyslipidemia, and postoperative complications, there was no significant effect of HINS.
