BEST BIPARTITION World Consensus Meeting
The "First World Consensus on Transit Bipartition Surgery" is a groundbreaking initiative in the field of bariatric and metabolic surgery, aimed at establishing a unified understanding and set of guidelines for the practice of intestinal bipartition surgery. This consensus is the result of collaborative efforts by leading surgeons, researchers, and healthcare professionals from across the globe who recognize the growing importance of this surgical procedure in the treatment of obesity and related metabolic disorders.

Introduction

Transit Bipartition (TB) was the first ever Metabolic and Bariatric Surgery (MBS) procedure designed to avoid mechanical restriction and malabsorption, primarily aiming at metabolic events. This relatively innovative approach brought the concept of purely metabolic surgery. It involves the strategic division and rerouting of the intestines to achieve significant weight loss and improve metabolic health. This procedure is a particularly beneficial alternative for patients with severe obesity and type 2 diabetes mellitus.

Goals of the Consensus
The main goals of the "First World Consensus on Transit Bipartition" are:
1. Standardization of Procedures: To outline specific surgical techniques and best practices, ensuring consistency and high success rates across different centers and regions.
2. Patient Selection Criteria: To define the ideal patient profile for intestinal bipartition surgery, ensuring that the procedure is performed in patients who will benefit most from the intervention.
3. Postoperative Care Guidelines: To provide recommendations for managing patients after surgery, including nutritional support, monitoring for complications, and follow-up care.
4. Long-Term Outcomes: To establish parameters for evaluating the long-term success and safety of the procedure, including weight loss sustainability and resolution of metabolic disorders.
5. Complications and Risks: To highlight potential complications and risks associated with the surgery and propose strategies for their prevention and management.

Key Areas of Focus in the Consensus:
1. Surgical Techniques: Detailed discussion of the various approaches to Transit Bipartitions, including its variations (one or two anastomoses, in the antrum or in the duodenum, isolated TB), the types of anastomoses, robotic vs. laparoscopic vs. open surgery, and variations in surgical design.
2. Mechanisms of Action: The physiological changes that occur following TB, such as altered sites of nutrient absorption, changes in gut hormones like GLP-1, PYY, FGF-19 and ghrelin, and their role in weight loss and metabolic improvement.
3. Outcomes and Effectiveness: A review of the short-term and long-term outcomes of patients undergoing TB, including weight loss percentages, improvement in comorbidities, and overall patient quality of life.
4. Multidisciplinary Approach: The importance of a multidisciplinary team approach, including surgeons, endocrinologists, dietitians, psychologists, and other healthcare professionals, in optimizing patient outcomes.

The First World Consensus on Transit Bipartition represents a significant step forward in the development of MBS, offering new opportunities for patients suffering from severe obesity and metabolic diseases. By establishing clear guidelines and fostering global collaboration, this consensus aims to improve patient outcomes, increase the safety and effectiveness of the procedure, and expand the understanding of its long-term benefits and risks. As research and practice in this field continue to evolve, the consensus document will likely be updated to incorporate new evidence and insights.
