Currently, hemorrhage remains the most common postoperative complication in patients with colon polyps, with an incidence of approximately 1.5%. The main reasons for postoperative hemorrhage are: the patient's own condition, the nature of the polyp and the operation. The number of patients treated for colon polyps has increased, postoperative care is confusing, medical resources are wasted, and the time span for postoperative diet recovery is large. However, studies on the effect of postoperative dietary recovery timing on postoperative polyp bleeding are rare.
