Colectomy commonly used clinically includes right colectomy and left colectomy. According to the location, nature and size of local colonic lesions found during the operation, partial colonectomy or subtotal colonectomy is selected.

1. Patients often have anemia and hypoproteinemia, and should be improved as much as possible before surgery. Give a nutrient-rich and low-slag diet, use fluids the day before surgery, and transfusion or plasma if necessary.

2. Pay attention to check heart, lung, liver, kidney and other important organ functions, coagulation mechanism and distant metastasis.

3. Prepare the intestines for 3 to 5 days, including:

If you have constipation, you can start using laxatives.

3From 3 days before the operation, use mannitol or enemas once a night, and clean enema the night before the operation.

Oral antibiotics such as sulfa drugs and metronidazole 3 to 5 days before the operation (in addition to oral sulfa drugs, 2 g of neomycin, once every 6 hours, 24 hours before the operation).

Kanamycin has no obvious irritation to the gastrointestinal tract and is less likely to cause diarrhea, which is better than neomycin. Oral administration was started 72 hours before the operation, 1 g per hour, 4 times a day, and then once every 6 hours, 1 g each time before the operation.

For those who are old, frail, and use antibiotics before and after surgery, they can simultaneously take nystatin 3 times a day, 1 million U each time to inhibit the growth of mold. Oral enteral antibiotics should be given at the same time as vitamin K.

4. For patients with left colon cancer and acute obstruction, the risk of one-stage resection is high. Generally, the right transverse colon fistula should be performed first, and after 2 to 3 weeks of decompression and preparation, radical surgery is performed; Lateral colon cancer is feasible for one-stage surgery, but if the condition is severe and the obstruction is severe, the cecum or colostomy should be performed first.

5. For patients undergoing left colectomy, an indwelling catheter should be placed before the operation.

6. Place a gastrointestinal decompression tube on the morning of the operation.

7. Patients with surgical removal of part of the colon will drink more coffee after surgery, and bowel movements will return to normal more quickly, and they can eat solid food and ventilate as soon as possible.
