What operation is total colectomy

summary

Now there are many names of operations, and we also have many operations that we have heard of but don't know much about, such as total colectomy. Speaking of this operation, the process is divided into several parts, which are relatively complex. Now let's talk about what total colectomy is.

What operation is total colectomy

First: incision, generally take the left side of the median abdominal incision, in order to facilitate upward and downward extension, exploration: comprehensive exploration, observe whether other organs have lesions, whether there is adhesion in the abdominal cavity. Free colon: after exploration, open the abdominal wall with automatic abdominal retractor, wrap the small intestine with plastic bag or gauze pad, and push it to the lower left. First, the ascending colon was separated and pulled to the left to expose the right paracolonic sulcus.

Second: from the caecum, use scissors to cut the right side of the peritoneum, up to the liver flexure of the colon. The cecum was put out of the incision and the mesentery of the terminal ileum was cut off to free the cecum, appendix and terminal ileum. The loose connective tissue between the ascending colon and the posterior abdominal wall was continuously separated. Pay attention to the course of the right ureter. Do not separate it from the loose connective tissue to avoid accidental injury and ligation.

Third, turn up and lift up the greater omentum, separate it from right to left along the greater omentum fold above the colon, cut off and ligate the greater omentum, continue to separate it to the left to the splenic flexure, and cut off the spleen colon ligament. Do not use excessive force when separating the ligament, so as to avoid tearing the inferior pole of spleen and causing bleeding. The splenocolonic ligament should be cut as far away from the spleen as possible to leave room. The left peritoneum was cut down from the splenic flexure along the left paracolon sulcus to separate the sigmoid colon, and the descending colon was separated from the posterior abdominal wall. At the same time, the left ureter was protected.
