Advancing Health Care in Regional Hub City: Introduction of Laparoscopic Sleeve Gastrectomy as Bariatric and Metabolic Surgery with Promising Results

Background: Numerous studies have demonstrated that bariatric and metabolic surgery (BMS) is a safe and effective option for obese patients. In Japan, national health insurance has covered laparoscopic sleeve gastrectomy (LSG) since 2014, increasing the number of procedures performed. This study analyzed 31 patients who underwent LSG at Okayama University Hospital, a regional core medical institution, between 2017 and 2024, focusing on safety and efficacy. Results: The findings revealed no severe complications and indicated significant weight loss and improvements in various metabolic diseases. However, challenges such as weight regain and interruptions in patient follow-up were identified. The remission rates for type 2 diabetes, hypertension, and dyslipidemia were 25%, 28.6%, and 56.3%, respectively. The study also noted potential pitfalls in surgical techniques, highlighting the importance of experienced medical teams. Conclusion: Although the weight loss rate in this study was slightly lower than the national average, the results remained promising. A multidisciplinary approach, encompassing thorough preoperative evaluations and consistent postoperative follow-up, was essential for success. BMS is highly effective and stands out as one of the key treatments for obesity. The study concludes that our facility has successfully introduced safe and effective BMS in the regional hub hospital by adhering to established guidelines.
