Managing Bariatric Surgical Emergencies: Evidence-Based Approaches for General Surgical Practice

Abstract

With the rising prevalence of obesity and the increasing utilization of bariatric surgery, general surgeons are increasingly encountering patients presenting with acute postoperative complications. While bariatric procedures are generally safe and effective, they carry a unique profile of surgical and metabolic emergencies due to altered anatomy, nutritional vulnerability, and technical complexity. Given that many patients present to non-bariatric centers, it is essential for general surgeons to be equipped to recognize and manage these emergencies. This narrative review aims to provide a comprehensive, procedure-specific guide for general surgeons on the diagnosis and management of bariatric surgical emergencies. It emphasizes timely recognition, key diagnostic principles, and tailored operative and nonoperative strategies, while also highlighting system-level challenges and disparities affecting outcomes. We reviewed the clinical presentation, pathophysiology, and evidence-based management of major categories of bariatric emergencies, including anastomotic leaks, internal hernias, bowel obstruction, bleeding, marginal ulcers, band-related complications, thrombotic events, and nutritional crises. We also examined the distinct challenges posed by revisional surgery. Consideration was given to disparities in access to care, delayed diagnosis, and the role of structured referral systems and enhanced recovery pathways. General surgeons play a critical frontline role in the management of bariatric emergencies. Familiarity with altered anatomy, procedure-specific risks, and atypical presentations is essential. Early imaging, prompt intervention, and multidisciplinary collaboration can significantly improve outcomes. In parallel, addressing systemic barriers and improving access to specialized care are necessary to ensure equitable and high-quality care for the growing population of bariatric surgery patients.
