Application of sigmoid colon anatomy to laparoscopic surgery / 中华胃肠外科杂志

ABSTRACT

Laparoscopic sigmoidectomy for cancer is considered as a simple surgical approach, which is suitable for primary laparoscopic surgery. However, the success of laparoscopic sigmoidectomy is closely related to the anatomical characteristics of the sigmoid colon. The length, adhesion and morphology of the sigmoid colon vary greatly. The differences of the length, width, adhesion and morphology of the mesentery are large. The distribution of vessels is diversified. The high ligation or the low ligation is still controversial. The location of the sigmoid colon cancer is also not constant. These problems have great influence on the operation. Before operation, the tumor must be accurately located and the anatomical characteristics of the sigmoid colon must be fully evaluated. The operation can be carried out smoothly and the complications during and after the operation can be reduced.
