Rectal cancer anastomotic leakage symptoms?

summary

Anastomotic leakage is the most common and serious complication of rectal cancer? Let's talk about it.

Rectal cancer anastomotic leakage symptoms?

The conditions of patients themselves include old age, physical weakness, malnutrition, hypoproteinemia, etc. if the patient's physical indicators are poor, and the body tissue repair ability is poor, it is not conducive to the recovery of patients after surgery. Especially when the preoperative plasma albumin is lower than 25g / L, the incidence of anastomotic leakage is very high.

About 19% of patients with rectal cancer complicated with intestinal obstruction have anastomotic leakage, which leads to intestinal stenosis and obstruction in varying degrees. Due to various reasons of malnutrition, severe damage of intestinal wall and edema before operation, the proximal intestinal tube can be significantly expanded, and the caliber of the intestinal tube at both ends of the anastomosis is asymmetric, which can not guarantee the exact anastomosis; At the same time, the incidence of postoperative intestinal infection in patients with intestinal obstruction is higher, which increases the possibility of anastomotic leakage.

Generally speaking, the distance between the tumor and the anus is close, that is, the location of the tumor is low and the operation is difficult; If there are some problems during the operation, such as unskilled operation of stapler, incomplete closure of rectal stump, and too thick adipose tissue in the anastomosis, these may lead to anastomotic leakage.

matters needing attention

① No matter what kind of anastomosis is used in the operation, we must ensure that the anastomosis is reliable and satisfactory; ② To ensure a good blood supply to the gastric wall and esophageal stump near the anastomotic site, that is, to protect the main blood supply vessels of the stomach and esophagus that should be preserved; ③ To reduce the tension at the anastomotic site, that is, to fully free the stomach, colon, small intestine and other organs, so as to ensure that there is no obvious tension at the anastomotic site; ④ Try to reduce the rubbing of gastric wall tissue;
