Preoperative preparation for laparoscopic rectal cancer surgery

Laparoscopic rectal cancer surgery can relieve patients' pain, improve their quality of life, and meet their functional rehabilitation needs. Like conventional surgery, laparoscopic rectal cancer surgery also requires adequate preoperative preparation to improve the success rate of the operation.

Physical condition

Before the operation, the patient's physical condition should be fully understood, and the heart, lung, liver and coagulation functions should be checked to see whether the patient can withstand prolonged surgical anesthesia and trauma. Especially for patients with other comorbidities such as hypertension and diabetes, strict diagnosis and treatment should be carried out to keep their physiological indicators basically normal before and during the operation.

Preoperative examination

Since laparoscopic surgery weakens the ability to touch lesions with hands, patients should undergo detailed barium enema examination, colonoscopy, abdominal CT or MIR examination before surgery. This will not only help doctors understand and determine the location and nature of the lesion and detect whether there is metastasis to the liver and abdominal cavity, but also conduct comprehensive preoperative staging, which is important for formulating surgical plans and achieving ideal therapeutic effects.

Bowel preparation

Bowel preparation before laparoscopy is also very important, because if the rectal contents are not clean, it is easy to contaminate the abdominal cavity. The specific bowel preparation is as follows: the patient eats liquid food 3 days before the operation, and starts taking intestinal antibiotics, such as neomycin or erythromycin, or a combination of both; oral laxatives 3 times in the morning, noon and evening 1 day before the operation; cleansing enema on the night before the operation and in the morning before the operation.
