Abstract:
Background & Objectives: Obesity affects the health of people and imposes costs on them. Since there are two common treatment methods, Roux-en-Y gastric bypass (RYGB) surgery and laparoscopic sleeve gastrectomy (LSG), and there is not enough and aggregated evidence on the cost-effectiveness of these two treatment methods in patients in Iran, therefore, this study was conducted to review the studies on the cost-effectiveness of these treatment methods.
Methods: This is a systematic review study. All articles published in English, which reviewed the cost-effectiveness of these two surgical methods during 2000-2017, were collected from the SCOPUS, PUBMED, MEDLINE, and EMBASE databases. The quality of these articles was evaluated by two researchers based on Grade's guidelines.
Results: The amount of body mass index (BMI) and reduced weight percentage in both methods showed the same effectiveness in weight loss. In Iran, the direct cost of RYGB services was $2991 in the public sector and $4221 in the private sector. For the LSG method, this was $1952 in the public sector and $3,177 in the private sector. ICER for the LSG method compared with the RYGB was $720 and $716 in the private and public sectors, respectively.
Conclusion: Laparoscopic sleeve gastrectomy (LSG) is more effective than the RYGB because it has lower cost and the same effectiveness.
