Inflammatory colon polyps are not very severe, and it is very rare for inflammatory polyps to become cancerous. However, if the inflammatory polyps are relatively large, it is necessary to undergo endoscopic treatment to remove them. After removal, pathological and tissue examinations are also needed to further confirm whether the polyps are indeed inflammatory and to rule out tumorous polyps, such as adenomatous polyps, among others. Additionally, about six months after the polyp removal surgery, a follow-up colonoscopy should be conducted to check for the recurrence of polyps. The primary causes of inflammatory colon polyps could be diseases such as ulcerative colitis or Crohn's disease.

What are the symptoms of colitis?

Colitis is relatively common in clinical settings, especially in the gastroenterology outpatient department, and it generally occurs in middle-aged and elderly patients. The disease typically begins with abdominal pain, diarrhea, or abnormal stools. The abdominal pain is characterized by episodic pain in the lower left or right abdomen, without persistent episodes and generally does not occur after the patient falls asleep at night. The diet is usually not related. Diarrhea manifests as watery stools or stools with a soft texture, without bloody stools. Abnormal stools are characterized by constipation, for instance, if the patient has not had a bowel movement for several days, with dry, sheep-dung-like stools that are difficult to expel. Typically, after a thorough colonoscopy, no colon tumors or polyps are found, but signs of congested and edematous colonic mucosa suggest a diagnosis of colitis. Generally, the condition isn't severe, and treatment primarily involves symptomatic management.

Risk of cancerous transformation in ulcerative colitis

The likelihood of cancerous transformation in ulcerative colitis is not very high. Generally, patients with ulcerative colitis who have had the disease for more than a decade and have not undergone treatment might be at risk of malignancy. Active treatment and regular gastroscopic checks can prevent the development of cancer. Therapeutically, options include using mesalazine for anti-inflammatory treatment, as well as using Bacillus cereus or Bifidobacterium triplex to regulate the intestinal flora. Additionally, if a patient with ulcerative colitis experiences chills, fever, and severe purulent bloody stools, it may be necessary to consider treatment with steroids and immunosuppressants. (Please use medication under the guidance of a physician.)

Symptoms of mild colitis

Chronic colitis is characterized by symptoms such as abdominal pain, diarrhea, and sometimes mucus in the stool resembling nasal discharge. These symptoms do not vary between mild or moderate to severe cases, as both mild and severe chronic colitis exhibit similar symptoms, making it impossible to distinguish between the severity from the symptoms alone. It is only possible to determine whether chronic colitis is mild or severe during a colonoscopy by observing the degree of mucosal hyperemia, edema, and erosion. Therefore, to differentiate whether chronic colitis is mild or severe, a definitive diagnosis must be made through a colonoscopy examination.

Can colitis cause back pain?

Colitis is commonly seen in clinical settings and generally does not cause back pain. The typical symptoms include abdominal discomfort and abnormal stools. It may manifest as discomfort in the left side of the abdomen, such as bloating and abdominal pain. Abnormal stools can be reflected by an increased frequency of defecation, generally more than two to three times. The character of the stool may change; for instance, a patient who previously suffered from constipation may now experience watery diarrhea or have stools that are relatively loose, but generally, there is no accompanying bloody stool, commonly referred to as stool with blood. Symptoms can also include a decrease in appetite, nausea, and vomiting. Common causes of back pain are generally considered to result from the urinary system or spinal pathology, such as ureteral stones, kidney stones, or herniated lumbar discs, etc. It is recommended for patients to undergo further examinations to clarify these conditions.

Can colitis be detected by an ultrasound?

Colitis cannot be definitively diagnosed with an ultrasound, as ultrasound is primarily used for diagnosing solid organs such as the liver, gallbladder, spleen, kidneys, and pancreas. For hollow organs, the diagnosis is obscured by gas and food inside the intestines, making ultrasound less effective. For patients suspected of having colitis, the best examination is a colonoscopy. A colonoscopy can clearly show the extent and severity of the inflammation. CT scans also hold diagnostic value as they can reveal thickening and edema of the colonic wall. CT scans are less painful compared to colonoscopies, which can be somewhat painful.
