Singapore experience in obesity surgery

Area of Science:

• Bariatric Surgery
• Obesity Management
• Surgical Outcomes

Background:

• Limited data exists on bariatric surgery outcomes in Asian populations due to lower obesity prevalence.
• Western bariatric surgery data is well-documented, but Asian-specific information is scarce.

Purpose of the Study:

• To analyze the outcomes of bariatric surgery in a series of Asian patients.
• To evaluate the safety and efficacy of gastric stapling and banding in a Singaporean cohort.

Main Methods:

• Analysis of a personal series of 40 patients undergoing gastric stapling and banding in Singapore from 1987 to 2003.
• Comparison of outcomes between open bariatric surgery (1987-1997) and adjustable gastric banding (1999-2003).

Main Results:

• Open bariatric surgery (n=26) resulted in significant BMI reduction and %EWL (Excess Weight Loss) over 8 years.
• Adjustable gastric banding (n=14) also showed substantial weight loss, with improved outcomes after adopting a new surgical technique.
• One case of band slippage and gastric prolapse occurred, which was resolved by modifying the surgical approach.

Conclusions:

• Bariatric surgery, including gastric stapling and banding, demonstrates safety and low operative morbidity in morbidly obese Asian patients.
• The pattern and magnitude of weight loss in this Singaporean cohort are similar to Western experiences.
• Surgical technique modifications can mitigate complications like band slippage.
