Description of the disease (onset time, main symptoms, hospital visited, etc.): Stomach pain has continued intermittently for 3-4 years, recently the pain has increased and this year after March began diarrhea, about 4 times a day. So in May in the local city hospital to do gastroscopy enteroscopy to check the stomach to check the stomach white class and sinusitis with yellow tumor, colorectal multiple polyps, the 10th colon polyps endoscopic excision. The polyps at the junction of the rectum and b can be seen as irregular bridging polyps without treatment. 13 gastric argon knife treatment. After the operation, the stool was still thin, and capsule endoscopy was done again, and the jejunum was found to be scattered with spotted patchy congestion and erosion, the ileum was scattered with several diverticula, a polyp of about 0.3 cm in diameter was seen in the lower ileum, and a submucosal bulge of about 2.0 cm in diameter was seen in the lower ileum, with a smooth surface, and the rest was not abnormal. After capsule endoscopy, it could not be handled in the local hospital and observation was recommended. The postoperative stomach pain was relieved. The stool was still thin and the frequency did not decrease. Some medications were prescribed at discharge. Trimebutine maleate capsule, rabeprazole sodium enteric capsule, aluminum phosphate gel, cumecoxylate widening capsule, and loperamide hydrochloride capsule. Explanation of the disease, and treatment goals and measures: The disease, prognosis and hazards are as follows: 1. Multiple polyps in the digestive tract, especially colon polyps: if not ideally controlled, there is a possibility of malignant transformation. Among the polyp growth characteristics, size is the most critical risk predictor, with a diameter greater than 1 cm, the possibility of malignant transformation increases sharply. Most of the causes are genetic factors. Acquired modifiable factors include improving dietary structure, improving digestive function, eliminating small intestinal bacterial overgrowth, and improving biochemical and ecological environment of colonic mucosal surface for the purpose of reducing polyp generation and growth; 2. Symptoms and nutritional status: The main sources of symptoms are the digestive tract (including gastric and intestinal irritation) and nutritional deficiency brought by reduced digestive and absorption function. Treatment and prevention focus: 1. Prognosis for polyps and malignant changes: dietary adjustment, improvement of food digestion and absorption, intestinal biochemical and ecological environment adjustment; increase the frequency of endoscopic follow-up; 2. Pharmacological treatment for symptoms: including acid suppressants, mucosal protective drugs, digestive enzymes, probiotics and antibiotics in a reasonable combination and in the right amount at the right time. In conclusion, the condition is more complex, more difficult to treat and the prognosis is more difficult to improve. It is recommended to follow up the treatment in the local hospital according to the principles I know.
