This symptom after gastric cancer surgery is considered to be caused by too short postoperative time and incision not recovered, and string gas is caused by weakened digestive function and poor gastric power after surgery.
Gastric cancer surgery is not a small operation, and more tissues are removed during the operation, so it is normal to have painful symptoms in the abdomen in the short term after the operation, which will improve or disappear as the operation time is extended. The patient’s pain can be ruled out by gastrointestinal ultrasound and abdominal CT (computed tomography) scan.
Gastric cancer surgery may remove most of the gastric tissue, resulting in smaller stomach volume and reduced gastric digestive capacity, and therefore the sensation of gas cascading. In addition, crosstalk can also be caused by postoperative complications, such as gastroparesis, which is caused by damage to the vagus nerve during surgery, but this complication is usually not long-lasting and can be recovered within a month after surgery.
