Introduction: Bariatric surgery exhibits promising outcomes for weight-loss and
obesity-related comorbidities. This study was conducted to contribute to local
data since differences in body composition and metabolism may affect
applicability of international studies on Asians.
Methodology: A before-and-after study was conducted at Asian Hospital and
Medical Center (AHMC). Data of patients who underwent Sleeve Gastrectomy
(SG) or Laparoscopic Adjustable Gastric Banding (LAGB) between January 1,
2006 to December 31, 2020 were collected through a review of records. The
primary outcomes were changes in weight, glucose, cholesterol, and blood
pressure post-operatively.
Results: Fifty-five patients aged 21-68 years old were included; 60% underwent
SG and 40% underwent LAGB. Mean baseline weight was 125.29(±30.66)kg and
mean BMI was 44.04(±8.73)kg/m2. Most patients (98%) were classified as obese
class II*. Both procedures showed decrease in weight and BMI at 1-month, 6-
months, and 1-year post-op. A significantly higher percentage of weight loss was
noted after SG compared to LAGB (49.11% & 17.91% respectively, 1-year postop).
There was a significant decrease in HbA1c among SG patients (6.49±1.05%
to 5.76±0.79%). Changes in FBS, and cholesterol parameters were not
significantly different pre- and post-op. Both groups showed significant decreases
in SBP (124.21±9.02mmHg to 120.52±7.05mmHg for SG; 130.29±17.39mmHg
to 117.86±11.88mmHg for LAGB), while only LAGB showed a decrease in DBP
(82.86±12.04mmHg to 74.86±7.36mmHg).
Conclusion: Both procedures showed weight loss; greater in SG. SG is associated
with adequate glycemic control as evidenced by lower HbA1c, and both showed
effective blood pressure control. Our data demonstrates that these procedures are
