Gastrointestinal polyps are benign lesions of the gastrointestinal tract, but they have a certain tendency to become malignant, which is why they should be removed in time after they are found. The malignancy is mainly related to the pathological type and size of the polyps.
Many people think that gastrointestinal polyp disease is completely cured after gastroenteroscopic polypectomy, but patients should not take it lightly. This is because gastrointestinal polyps are prone to recurrence and should be checked regularly under the guidance of a doctor.
Gastrointestinal polyps are benign lesions of the gastrointestinal tract, but they have a certain tendency to become malignant, which is why they should be removed in time after they are found. The malignancy is mainly related to the pathological type and size of the polyps. Adenoma is the most common gastrointestinal polyp and one of the most common precancerous lesions in the digestive tract, which takes about 5-20 years to develop.
Gastrointestinal polyps can be detected by endoscopy (e.g. gastroscopy, colonoscopy) and can be removed at the same time of detection, which is currently the preferred method of treatment for gastrointestinal polyps. However, after removal, we should not take it lightly and still need to follow up regularly, because there is still a possibility of recurrence after removal of gastrointestinal polyps.
It is known that the redetection rate of polyps after treatment is 13%-86%. Newly detected polyps are divided into recurrent polyps with residual polyp re-growth in addition to some new polyps and missed polyps in the large intestine. Another study showed that for colorectal cancer of adenomatous origin, regular colonoscopic follow-up after polypectomy reduced the incidence of colorectal cancer by 88% in total. In order to maintain a polyp-free intestine and prevent the occurrence of gastrointestinal cancer, it is necessary to establish a cost-effective follow-up gastroscopy schedule.
The frequency of review varies according to the high and low risk of polyps.
High-risk group refers to those with one of the following conditions: multiple adenomas, adenomas >2 cm in diameter, broad-based villous or mixed adenomas, adenomas with severe atypical hyperplasia or carcinoma in situ, or adenocarcinoma with invasive carcinoma.
The low-risk group refers to patients who develop a single, tipped (or broad-based but <2 cm tubular adenoma) adenoma with mild or moderate atypical hyperplasia. For patients in the high-risk group, gastroscopic review is recommended 6 months after resection and reexamination at one-year intervals if two consecutive reviews are negative. For patients in the low-risk group, gastroscopy is recommended 1 year after resection, and if two consecutive reviews are negative, it can be done every 3 years. Post-operative care of colon polypectomy: 1.After surgery, according to the patient’s polyp site, size, number, intraoperative conditions, etc., fasting for 24-72 hours, intravenous nutritional support treatment, after lifting the fasting into a liquid or semi-liquid diet, avoid stimulating food, keep the large soft and fluent, 1 week no alcohol, if the color of the stool is found to be black, the patient should follow medical advice to fast and notify the doctor. 2, bed rest within 3 days of surgery, after that, appropriate exercise can be performed, light physical activity within 2 weeks, avoid heavy physical labor for 1 month to prevent delayed intestinal bleeding due to strenuous activity. 3, pay attention to observe any postoperative bleeding, perforation and other complications, notify the doctor of any abnormalities, observe the color, nature and amount of stool, if there is a drop in blood pressure, increased heart rate and bloody stool suggesting intestinal bleeding, inform the doctor immediately to take measures.
