K91: Postprocedural disorders of digestive system, not elsewhere classified

Postprocedural disorders of the digestive system are medical conditions that happen as a result or complication of a surgical procedure involving any part of the digestive tract, which includes the esophagus, stomach, small intestine, large intestine, and rectum. This group of disorders can occur if the body responds abnormally to surgical interventions, potentially leading to complications like infection, inflammation, bleeding, obstruction, or functional disorders. Symptoms can vary widely and may include abdominal pain, nausea, vomiting, alterations in bowel movements, and difficulty swallowing. The progression of these disorders depends on multiple factors such as the type of procedure performed, individual health status, and the timeliness and effectiveness of management or intervention after the surgical procedure. They typically do not spread from person to person, as they are not infectious or contagious in nature, but are often a result of the body's reaction to a surgical event within the digestive system.
