What are the complications of colon cancer surgery

summary

A friend of mine has colon cancer, and his normal life has been greatly affected. And now he has been in hospital. When he went to see him, the doctor said that he should have the operation as soon as possible, but there may be some complications after the operation. Next, I'll talk about the complications of colon cancer surgery.

What are the complications of colon cancer surgery

First, anastomotic leakage is caused by mesenteric hematoma caused by operation, which affects anastomotic blood supply; or anastomotic tension is too high, and suture foreign body stimulation affects healing; or in case of perforation or obstruction, inflammatory edema of intestinal wall is obvious, resulting in anastomotic stoma and adjacent abscess. Attention should be paid to reduce the injury during the operation. The anastomotic tension should not be too large. Strict aseptic operation can reduce the incidence of anastomotic leakage.

Second, anastomotic stenosis is often caused by improper ileal resection slope and poor suture technique; it can also be caused by adhesion and distortion near the anastomosis, leading to partial or complete obstruction. When cutting the ileum, the inclined plane should be increased to increase the diameter of the ileum. When anastomosing the inner layer of the anterior wall, attention should be paid to avoid suturing to the contralateral mucosa. After the anastomosis, the thumb and index finger were used to check the anastomotic stoma outside the intestinal canal. If a few sutures were continuous with the contralateral side, the fingers could be used to separate the anastomotic stoma. If the anastomotic stoma was too small, the anastomotic stoma should be re anastomosed.

Third: ureteral injury, if the tumor is too large, adhesion around the retroperitoneum, so that the anatomical relationship is not clear, or the operator is negligent, in the separation of the outer edge of the colon and its mesentery, the ureter can be damaged, punctured or cut off by mistake, separation should be gentle and careful, can first find the ureter, to protect. However, it should not be dissociated too much to protect the ureter. Excessive dissociation can affect blood circulation and form ureteral fistula after operation.

matters needing attention

Colon cancer surgery will bring many complications to patients, such as the destruction of the ureter. Because sometimes the operation will remove the tissue cells around the colon by mistake, the most important thing is that there will be some adverse reactions in the duodenum and digestive tract.
