Relapse after rectal cancer surgery means what it means and what can be treated

In the early stage of colorectal cancer**, the reason why postoperative chemotherapy is done is because there may be a certain amount of tumor cells in the lymphatic fluid and blood in the human body, so for the tumor cells that exist in the patient's blood and lymph after surgery**, further intravenous chemotherapy is required to further kill the tumor cells.

Surgery followed by chemotherapy for rectal cancer is mainly determined by the stage of the tumor.

For patients with T1-2N0M0 or contraindications to chemoradiotherapy, direct surgery is recommended, and preoperative neoadjuvant chemoradiotherapy is not recommended. For patients with T3 stage and/or positive lymph nodes, in order to improve the rate of surgical resection and anus-preserving and prolong the disease-free survival of patients, preoperative chemoradiotherapy should be performed according to the current diagnostic standards. For patients with T4 or locally advanced unresectable rectal cancer, neoadjuvant chemoradiotherapy is mandatory.

Generally speaking, rectal cancer is a very common malignant tumor of the digestive system. Generally speaking, unless the earliest rectal cancer is surgically resected, chemotherapy is not required, and other rectal cancers require six to eight cycles of chemotherapy after surgery to be effectively prevented**.

Because there may be a certain amount of tumor cells in the lymphatic fluid and blood in the human body, after surgery, several courses of systemic intravenous chemotherapy can be done according to the results of the examination.

Because the surgery is to remove our tumor tissue. It is impossible to completely remove every tumor cell, so it is necessary to do chemotherapy after surgery.

There are pros and cons to chemotherapy, patients with colorectal cancer stage 1, patients in the early stage, do not need to do chemotherapy at all, and do not need to do radiotherapy, this is an early stage patient. Stage 2 patients have a chemotherapy treatment. Stage 3 patients who undergo chemotherapy after surgery can (prevent) local ** and distant metastases as early as possible.

Complications after colorectal cancer surgery are divided into short-term complications and long-term complications, short-term complications may be directly related to surgery, such as surgical wound infection, intra-abdominal surgery local infection, and the impact of surgery on the whole body, postoperative such as pneumonia, urinary tract infection, including some cardiovascular and cerebrovascular complications, etc., which are short-term complications after colorectal cancer surgery; For a long time, whether it is colon cancer or rectal cancer, it is necessary to remove a fairly long section of intestine, so it may cause some disorders and some effects on gastrointestinal function, especially after rectal cancer, some patients may have increased bowel movements, frequent bowel movements, and laborious bowel movements, but these complications will gradually and slowly alleviate after about half a year to a year of recovery.

After colorectal cancer surgery, the main complications are:

1. Poor healing of anastomosis: advanced age, preoperative chemoradiotherapy, and malnutrition are high-risk factors;

2. Postoperative infection: such as abdominal infection, chest infection, urinary tract infection, deep venous catheter infection, etc.;

3. Hemorrhage: wound hemostasis, including electrosurgical hemostasis, ultrasonic coagulation, ligation hemostasis, etc., intraperitoneal bleeding occurs, and secondary surgery is required to stop bleeding;

4. Perioperative myocardial infarction, cerebral infarction, and venous thrombosis of the lower limbs: standardized ** and perioperative nursing, the incidence is very low.

Rectal cancer is more likely to occur after surgery:

1. Rectal cancer, especially after low rectal resection and anastomosis, often has changes in defecation function, such as increased stool frequency, incontinence, etc., this group of comprehensive group signs mainly uses some symptomatic drugs** or changes in part of the diet, taking traditional Chinese medicine, etc., most of them can be compensated in about 3 months.

2. Voiding dysfunction after rectal cancer surgery. i.e., bladderurinary retention.

The reason for this is that the parasympathetic nerve of the pelvic wall is damaged during pelvic dissection after rectal cancer**, which is neurogenic and manifests as detrusor muscle relaxation.

Bladder contraction and bladder distension are gone, and a catheter can be placed to compensate the bladder for compensatory training, and drugs can be used to control urinary tract infections.

3. Sexual dysfunction. Rectal cancer is resected about now.

of patients with sexual dysfunction.

The cause is injury to the inferior abdominal plexus during surgery.

i.e., the sympathetic plexus. Some patients recover within six months to a year. Take Chinese medicine**.

It helps a lot with restorative functioning.

Usually, patients with rectal cancer can perform sexual function after surgery with warm sitz baths or oral administration of sildenafil and other drugs**, and oral methylcobalamin can promote nerve recovery.

Suggestions: It is recommended that patients can do relatively light physical exercise for about two to three months after surgery to improve local blood circulation, and then be sure to abstain from sexual life in severe cases.

Rectal cancer patients can be treated with Chinese herbal medicine for a period of time after surgery to prevent metastasis.
