The advantages of using a circular stapler to anastomose the digestive tract are simple, labor-saving, safe, reliable, convenient and fast, and can effectively prevent the occurrence of anastomotic leakage, stenosis, bleeding and other complications. Thus, it has overcome the worries of esophagojejunostomy or abdominal esophagogastrostomy such as deep site, poor exposure, time-consuming and laborious, complicated and unreliable operation, and concerns of multiple esophagus resection, increased the anus preserving rate of lower rectal cancer, and improved the quality of life of patients. When opening the stapler, it should be checked that if the seamless staples fall off and all parts of the stapler are in the correct position.
After anastomosis using a circular surgical stapler, it is necessary to check whether the intestinal wall at both ends of the incision is a complete ring, and it is very important to pay attention to whether it is a full-thickness ring. If there is no mucosal layer at one end, anastomotic leakage may occur. The direction of the defect should be checked, and the seromuscular layer should be tightly sutured to prevent anastomotic leakage. Secondly, it is necessary to check whether the anastomosis is complete, and it is the key to check the back wall. If there is any leakage of the anastomosis, it is necessary to make a few stitches at the defect, and finally, conduct an inflation test until there is no leakage.
