Flatulence after surgery for stage 2a sigmoid colon cancer may be due to intestinal flatulence, intestinal adhesion, tumor recurrence or metastasis.
1. Intestinal flatulence: after receiving surgical treatment for sigmoid colon cancer, the intestinal function of patients will be reduced in the first few days after the completion of surgery, resulting in the appearance of intestinal flatulence, which may trigger abdominal distension and pain.
2. Intestinal adhesion: after being discharged from the hospital, the patient develops distension and pain, which may be caused by intestinal adhesion, abnormal adhesion occurring between intestines and intestinal tubes, between intestinal tubes and peritoneum, and between intestinal tubes and intra-abdominal organs, which results in incomplete intestinal obstruction, and the development of distension and pain.
3. Tumor recurrence or metastasis: if patients have bloody stools in addition to abdominal distension and pain, they need to go to hospital for relevant examination, which may be tumor recurrence or metastasis.
There may be other reasons for postoperative distention and pain of sigmoid colon cancer patients, so it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy.
