It has been 4 months since 72-year-old Uncle Su had blood in his stool. “Nine out of ten people have hemorrhoids”, thought Su, “It’s okay, it must be hemorrhoids.” So Su did not go to the hospital for treatment. During a conversation with his son, Mr. Su learned about this situation and dragged him to the gastrointestinal surgery, and the examination result was like a bolt from the blue, “colon cancer with liver metastasis”. As a result of neglecting the early manifestations of colorectal cancer and delaying the treatment, Su Lao Han now has cancer and liver metastasis, which is a late-stage tumor, and in earlier years, doctors would be helpless and the patient would be sentenced to “death”. After fully grasping Su’s condition, we initially decided to adopt the most advanced comprehensive treatment plan. The gastrointestinal surgery department, together with the ultrasound department, firstly performed ultrasound microwave interventional thermotherapy on Mr. Su, and the treatment effect was very satisfactory, and the metastatic liver tumor disappeared. According to the new progress, the experts then decided to perform laparoscopic radical rectal cancer surgery on Su Lao-bai, which was very successful. After the careful treatment and care by the medical staff, Su Lao-bai recovered well, and all indicators returned to normal, and he was discharged from the hospital soon. At present, with the increasing intake of high-protein, high-fat and low-fiber food, coupled with the decrease of exercise, the incidence of colorectal cancer is increasing, and due to the lack of attention to early symptoms, some patients are found to have liver metastasis or lung metastasis when they visit the doctor. Therefore, attention should be paid to the early detection and early diagnosis of gastrointestinal malignant tumors, and even at the advanced stage, we still should not give up lightly. At present, due to the combination of ultrasound intervention and various technologies of minimally invasive surgery, colorectal cancer patients can get the best treatment effect and patients can achieve tumor-free survival and are expected to be clinically cured.
