This comprehensive and practical guide specifically addresses both the common and rare surgical complications that may arise following gastric resection for cancer. As one of the more complex and invasive procedures in gastrointestinal surgery, gastric resection is associated with a high risk of major morbidities, which can sometimes lead to severe or even fatal outcomes. The book provides detailed insights into the diagnosis and management of postoperative complications, outlining when to adopt conservative approaches, as well as when to utilize minimally invasive or more invasive procedures. Each chapter is organized around specific complications, discussing their severity and offering practical advice on how to prevent and treat these adverse events based on the latest scientific literature. This guide is an essential resource not only for surgeons performing gastric resections but also for clinicians involved in the care of gastric cancer patients.
