Whether a patient can eat sea cucumber after surgery for gastric cancer depends on whether the patient has fully recovered from the gastrointestinal function and the patient’s own physical condition: a. If a patient undergoes minimally invasive laparoscopic surgery for distal gastric cancer, the surgery is relatively less traumatic, the patient recovers faster after surgery, and there is no more accumulated blood and fluid in the abdominal cavity. Patients who eat sea cucumber in daily life without skin itching, redness and swelling and other allergic phenomena can eat sea cucumber in small amount, which is rich in animal protein and is conducive to faster recovery of patient’s condition. Second, if the patient undergoes total gastrectomy under open surgery due to gastric malignant tumor, the surgery is more traumatic, and the patient has more inflammatory exudate in the abdominal cavity after the surgery, and the intestinal tube is obviously dilated, without restoring ventilation and laxity, the patient’s consumption of sea cucumber will increase the burden of gastrointestinal function, which is not conducive to the recovery of the patient’s condition.
