Why Should Biopsy Be Performed For Endoscopy?

At present, in the field of digestion, endoscopy is ubiquitous and has become an indispensable means for the diagnosis and treatment of digestive tract diseases. Despite the vigorous development of therapeutic endoscopy in recent years, according to the investigation, the main purpose of endoscopy is still the diagnosis of gastrointestinal diseases.

Endoscopy is mainly used to find gastrointestinal mucosal erosion, ulcers, masses, stenosis or vascular lesions. Qualitative diagnosis, such as inflammatory, tumor or malignant lesions, requires endoscopic biopsy. Endoscopic biopsy refers to the observation of mucosal abnormalities under gastroscopy or colonoscopy, but the lesion nature cannot be determined. The mucosal tissue is biopsied by forceps and sent to the pathology department, where the pathologist observes the morphological characteristics of cells under the microscope for final diagnosis.

It is often asked if there is an alternative to the "painful" gastroscopy and colonoscopy, but there is none. Because under endoscopy, you can look directly at the lesions, just like the flashlight looking for lesions on the gastric mucosa or intestinal mucosa, you can see or not see the lesions intuitively. Most importantly, if a problem is suspected, the tissue can be directly extracted by forceps for further examination, and can also be directly treated, which cannot be replaced by other examinations such as B-ultrasound and CT.

Endoscopic examination is more and more popular, but also for other imaging examination irreplaceable advantage, microscopically small mucosal lesions can be directly observed, of course that require a doctor's great knowledge of experience, carefully and identify disease see tiny lesions, accurately grasping organization, pathological biopsy qualitative diagnosis, the patient has a vital role.

Endoscopic biopsy plays an important role in the diagnosis, differential diagnosis and prognosis assessment of clinical diseases.

For the type of inflammatory disease or the discovery of early tumors, the degree of inflammation, activity, and even the cause of inflammation can be assessed. Such as gastric helicobacter pylori infection or duodenal fecal strongylodes infection. For neoplastic diseases, it can determine the benign and malignant tumor, as well as the degree of differentiation, and guide the determination of surgery and chemotherapy.

In addition, biopsy of small lesions may find very early precancerous lesions, which plays an important role in timely treatment to prevent cancer progression.

In order to improve the diagnostic level of gastrointestinal diseases through endoscopy, endoscopists are not only required to have skilled endoscopic techniques, but also to master endoscopic biopsy techniques, be familiar with clinical knowledge related to mucosal lesions, and be able to comprehensively analyze lesions. Endoscopy should not only pursue the length of endoscopic operation time, but also pursue a low rate of missed diagnosis and a high rate of confirmed discovery.
