Colon cancer surgery is done through conventional open or laparoscopic.
Conventional laparotomy firstly gives anesthesia to the patient, and after successful anesthesia, the patient’s abdomen is sterilized by using iodine povidone, and sterile towel is spread, and then an abdominal incision is made to open up the abdominal cavity, and the patient is firstly examined whether there is ascites, and then the size of the colorectal cancer foci, the depth and area of infiltration, and the metastatic situation of lymph nodes are observed.
Subsequently, the colon part where the lesion was located was dissected, ligated and dissected at its root, and at the same time, the lymph nodes at the root of the inferior mesenteric vessels were cleared, the mesentery of the colon was dissected, and the colon was resected from the tumor part.
Next, the head of the anastomosis was placed in the upper mesentery, and the anastomosis was extended from the anus to articulate with the upper mesentery to anastomose the upper mesentery with the lower mesentery. Finally, the mesentery was sutured, rinsed with distilled water, and the drainage tube was placed to close the patient’s abdominal cavity and suture the abdominal incision to end the surgery.
Laparoscopic surgery has the same surgical procedure as conventional open surgery, only the location of incision and the size of incision are different, and during the surgical procedure, conventional open surgery is performed through naked eyes, while laparoscopic surgery relies on laparoscope.
How exactly a patient can undergo colon cancer surgery needs to be decided according to the patient’s specific situation under the advice of the doctor.
