anastomotic leak
Postoperative complication where surgical connection between bowel segments fails, leading to contamination and potential serious morbidity.
Full Definition
Anastomotic leak represents one of the most serious complications in gastrointestinal surgery, occurring when the surgically created connection between bowel segments breaks down, allowing intestinal contents to escape into the peritoneal cavity. This complication can range from small, contained leaks that heal with conservative management to major disruptions requiring emergency reoperation. Anastomotic leaks are associated with increased mortality, prolonged hospital stays, and long-term functional complications. Risk factors include poor tissue perfusion, tension at the anastomosis, patient comorbidities, and technical factors related to the surgical technique employed.
