Summary
This study presents a modified one-anastomosis gastric bypass (OAGB) for safe and effective bariatric surgery in patients with grade 1 and 2 obesity. The procedure ensures normal BMI and allows for full gastrointestinal examination post-surgery.
Area of Science:
- Bariatric Surgery
- Gastrointestinal Surgery
- Obesity Treatment
Background:
- Obesity grade 1 and 2 requires safe surgical options.
- Current bariatric procedures may pose risks of malabsorption or limit gastrointestinal examinations.
- Need for reversible surgical methods in bariatric surgery.
Purpose of the Study:
- To develop a safe and effective surgical method for obesity grade 1 and 2.
- To minimize risks of intestinal malabsorption.
- To ensure no limitations for postoperative gastrointestinal examination and maintain surgical reversibility.
Main Methods:
- Modification of one-anastomosis gastric bypass (OAGB).
- Formation of a gastric tube using a stomach catheter.
- Manual retrogastric retrocolic anastomosis in an "end-to-side" fashion.
Main Results:
- Successful surgery in 16 patients (15 female, 1 male) aged 23-48.
- Mean BMI reduced from 35.15 kg/m² to normal levels within 6 months.
- Excessive weight loss ranged from 81.8% to 125%.
- Postoperative esophagogastroduodenoscopy and retrograde duodenoscopy were successful in all examined patients.
Conclusions:
- Modified OAGB with a short limb is safe and effective for bariatric surgery.
- The procedure facilitates postoperative diagnostic and therapeutic endoscopic interventions.
- Recommended for obesity grade 1 and 2 pending further clinical trials and long-term data.
