Introduction
The Mini Gastric Bypass (MGB) is a bariatric procedure that has become popular in recent years due to its efficacy and safety in the treatment of obesity and related diseases (Rutledge & Kular, 2019). This article aims to review the surgical technique, advantages, potential complications, and long-term outcomes.
Mini Gastric Bypass Procedure (MGB)
MGB is a laparoscopic procedure that combines a gastric restriction and a biliopancreatic diversion (Musella et al., 2017). The technique involves the creation of a small tubular gastric pouch along the lesser curvature of the stomach using surgical staplers (Rutledge & Kular, 2019). An anastomosis is then performed between the gastric pouch and the small intestine at a distance of 150 to 200 centimeters from the ligament of Treitz (Musella et al., 2017). This design allows for rapid weight loss by limiting food intake and reducing nutrient absorption.
Advantages
MGB has several advantages compared to other bariatric procedures. First, it is a single-anastomosis procedure, which simplifies the surgical technique and decreases surgery time (Musella et al., 2017). In addition, perioperative morbidity and mortality are low, and the long-term complication rate is also lower compared to other bariatric procedures (Rutledge & Kular, 2019).
Another advantage of MGB is its effectiveness in weight loss and resolution of obesity-related comorbidities, such as type 2 diabetes, hypertension, and dyslipidemia (Noun et al., 2012). Studies have shown that MGB is superior to Roux-en-Y gastric bypass (RYGB) in terms of weight loss and metabolic control (Lee et al., 2012). In addition, MGB is a potentially reversible and adjustable procedure, allowing for greater flexibility in postoperative management (Rutledge & Kular, 2019).
Complications
Despite its advantages, MGB is not without potential complications. Early complications may include bleeding, anastomotic leakage, infection, and pulmonary thromboembolism (Musella et al., 2017). Late complications include anastomotic stricture, marginal ulcers, malabsorption syndrome, nutritional deficiencies, and alliasic cholecystitis (Noun et al., 2012). Importantly, most of these complications can be prevented or managed with proper follow-up and multidisciplinary patient management (Musella et al., 2017).
Long-Term Results
Long-term studies have demonstrated that MGB is an effective and durable procedure for weight loss and management of obesity-related comorbidities (Rutledge & Kular, 2019). Average weight loss in patients undergoing MGB ranges from 75% to 85% of excess weight, with a long-term success rate of approximately 70% (Noun et al., 2012). In addition, resolution of comorbidities such as type 2 diabetes, hypertension, and dyslipidemia is significantly higher compared to other bariatric procedures (Lee et al., 2012).
However, it is critical that patients undergoing MGB follow a program of follow-up and adherence to nutritional and lifestyle guidelines to maintain long-term results (Rutledge & Kular, 2019). This includes taking vitamin and mineral supplements, engaging in regular physical activity, and regular medical and nutritional follow-up.
Conclusion
The Mini Gastric Bypass is an effective and safe bariatric procedure in the treatment of obesity and related diseases. Its simplified surgical technique, rapid weight loss, resolution of comorbidities and low complication rate make it an attractive option for patients and surgeons. However, adequate follow-up and multidisciplinary management is essential to prevent and treat possible complications and ensure long-term results.
