This comprehensive text offers an authoritative, practice-oriented guide to the full spectrum of complications associated with metabolic and bariatric surgery, positioning these challenges within the broader framework of obesity as a chronic disease. Beginning with foundational considerations—quality improvement initiatives, preoperative assessment, and the development of technical expertise—the book builds a critical baseline for understanding both patient selection and risk mitigation. Detailed chapters on radiologic and endoscopic evaluation equip clinicians with essential diagnostic tools, while an emphasis on systems such as MBSAQIP underscores the importance of data-driven performance and patient safety in modern bariatric practice.

The core of the text provides an in-depth exploration of procedure-specific complications across the most commonly performed bariatric operations, paired with clear, evidence-based strategies for management. From nutritional, hepatic, renal, and endocrine consequences to psychological and reflux-related concerns, the book addresses the multidisciplinary realities of patient care. A dedicated section on revisional and endoluminal interventions offers technical guidance for managing complex or failed primary procedures, complemented by discussions of emerging therapies and evolving surgical approaches. Concluding with additional clinical considerations—including hernias, pregnancy, acute emergencies, and the integration of pharmacologic therapies—this book serves as a definitive resource for surgeons and care teams navigating the increasingly complex landscape of bariatric and revisional surgery.
