Abstract:
Objective:To investigate the effect of laparoscopic sleeve gastrectomy (LSG) on weight loss in patients with different degrees of obesity.Methods:A retrospective analysis was performed on 152 patients with obesity who underwent LSG in Affiliated Huaian No.1 People′s Hospital of Nanjing Medical University from March 2019 to May 2022, including 119 females (78.3%) and 33 males (21.7%), with a mean age of (30.9±7.9) years (ranging from 18 to 58 years). The body mass index (BMI) was 30.0-34.9 kg/m 2, 35.0-39.9 kg/m 2 and ≥40.0 kg/m 2 in Ⅰ, Ⅱ and Ⅲ objesity groups respectively ( n=38, 57, 57). The body measurements, biochemical indexes, percentage of excess weight loss (%EWL) and percentage of total weight loss (%TWL) were collected and analyzed before and after surgery at 1, 3, 6, 12 months. Statistical analysis was conducted using SPSS 22.0 software. Results:LSG was successfully implemented in 152 patients. Body weight, BMI, waist circumference, hip circumference, waist-to-hip ratio, liver function, blood glucose and lipid parameters all decreased at each time point of postoperative follow-up, while uric acid increased at 1 month and decreased at 3, 6 and 12 months after surgery and then gradually decreased. At 12 months after surgery, the body weight was (75.9±17.0) kg ( t=15.14, P<0.001), BMI (26.2±3.7) kg/m 2 ( t=14.44, P<0.001), waist circumference (89.0±10.7) cm ( t=9.20, P<0.001), hip circumference 100.6±7.6 cm ( t=12.67, P<0.001), alanine aminotransferase (18.2±16.6) μ/L ( t=2.83, P=0.018), aspartate aminotransferase (15.2±14.2) μ/L ( t=2.84, P=0.018), fasting plasma glucose (4.6±0.5) mmol/L ( t=2.01, P=0.026), triglyceride 1.1±0.5 mmol/L ( t=3.71, P=0.005) and uric acid 340.2±102.7 μmol/L ( t=4.46, P=0.001), all were lower than those before surgery with statistical significance. At 6 months after surgery, the %EWL in Ⅰ, Ⅱ and Ⅲ obesity groups was (92.7±35.5) %, (86.1±16.0) % and (67.5±14.0) % respectively, with statistical significance among the 3 groups ( F=5.38, P=0.010). The %TWL was (20.5±7.4) %, (28.5±5.2) % and (28.9±6.1) % in the three groups respectively, and the overall difference was statistically significant ( F=3.50, P=0.043). At 1 year after surgery, there was no significant difference in %EWL and %TWL among the 3 groups. Conclusions:LSG was effective in treating simple obesity, with improvements of body weight, waist circumference, hip circumference, liver function, blood glucose and lipid and uric acid. In the first 6 months after surgery, %EWL in patients with class Ⅰ obesity was higher than that in patients with class Ⅲ obesity, achieving relatively better weight loss. However patients with class Ⅲ obesity also experienced significant weight loss until 1 year after surgery.
