Abstract
Introduction: With over 580,000 procedures carried out globally each year, bariatric surgery has emerged as one of the most successful long-term therapies for obesity, a global health issue that affects over 650 million adults worldwide. In addition to its morbidities, bariatric surgery, a proven treatment for morbid and other forms of obesity, has a number of early and late postoperative problems. Objective: This study aimed to assess the use of interventional radiology in the minimally invasive therapeutic management of problems, in addition to its uses in bariatric treatment. Methods: PubMed, Scopus, and Web of Science databases were utilized for conducting a narrative review. Peer-reviewed articles published in English between 2010 and 2025 have been studied primarily for techniques guided by IR for the treatment of problems post-bariatric surgery. Results: Interventional radiology helps immensely for the treatment of various common post-operative problems such as gastrointestinal leaks, strictures, abscesses, and bleeding. Various image-guided techniques such as percutaneous drainage, angiogram and embolization, balloon dilatation, and stenting have been proven to be successful and have reduced morbidity rates and lower hospital stay time for the patient as compared to certain individuals undergoing surgery. Conclusion: Interventional radiology is already a key component of modern postoperative therapy, with efficient, minimally invasive approaches to a variety of problems after bariatric surgery. A further step toward better patient outcomes would be the more extensive integration of interventions, standardized care pathways, and prospective study based on outcomes.
