What does "sigmoid colon tubular adenoma" mean?

Generally, sigmoid colon tubular adenoma is a relatively common type of tumor among gastrointestinal polyps. If physical discomfort occurs, it is recommended to seek medical attention promptly and receive treatment under the guidance of a qualified physician. The specific analysis is as follows:

Sigmoid colon tubular adenoma is a benign tumor occurring on the mucosa of the sigmoid colon and represents one type of colorectal polyp. It primarily arises from abnormal proliferation of intestinal epithelial cells and originates in the colonic mucosal epithelium, usually growing in a polypoid form. This type of adenoma tends to grow slowly and is mostly benign; however, if left untreated, it carries a certain risk of malignant transformation. Therefore, close monitoring is necessary to prevent malignant progression.

In the early stages of the disease, sigmoid colon tubular adenoma often presents no obvious symptoms. As the adenoma gradually enlarges, patients may experience abdominal discomfort, changes in bowel habits, increased or decreased frequency of defecation, and rectal bleeding.

Small, pedunculated adenomas can be removed via endoscopic techniques such as snare polypectomy or electrocautery. Larger, sessile, or adenomas with suspected malignant potential may require surgical resection of a portion of the intestinal segment. Patients should maintain healthy lifestyle habits and undergo regular routine stool tests, fecal occult blood testing, and necessary colonoscopies to facilitate timely detection and management of health issues.
