Why Do We Need Biopsy Pathology For Endoscopy?

At present, endoscopic examination is ubiquitous in the field of digestion, and has become an indispensable means for the diagnosis and treatment of digestive tract diseases. Although the development of therapeutic endoscopy has been booming in recent years, according to investigations, the main purpose of endoscopic examination is still the diagnosis of gastrointestinal diseases.

Endoscopic examination is mainly used to find erosion, ulcer, mass, stenosis or vascular lesions of gastrointestinal mucosa. Qualitative diagnosis, such as inflammatory, tumor or malignant lesions, needs to be confirmed by endoscopic biopsy. Endoscopic biopsy refers to the observation of mucosal abnormalities under gastroscopy or colonoscopy, but the nature of the lesion cannot be determined. Through biopsy clamp, the mucosal tissue is sent to the pathology department, and the pathologist can observe the morphological characteristics of the cells under the microscope to make the final diagnosis.

It is often asked if there is an alternative to "painful" gastroscopy and colonoscopy, and there is not yet one. Because under endoscopy, the lesions can be directly seen, just like the flashlight searching for lesions on the gastric mucosa or intestinal mucosa, and the lesions can be seen or not seen directly. Most importantly, if a problem is suspected, the tissue can be directly clipped for further examination, in addition to direct treatment, which cannot be replaced by other tests 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 evaluation of clinical diseases.

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

In addition, biopsy of small lesions may detect very early precancerous lesions, which plays a crucial role in preventing cancer progression through timely treatment.

In order to improve the diagnostic level of gastrointestinal diseases through endoscopy, endoscopists are required not only to have skilled insertion skills, but also to master endoscopic biopsy technology, be familiar with the clinical knowledge related to mucosal lesions and the ability 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 diagnosis and discovery.

Only in this way can the advantages of early detection and correct diagnosis of lesions by endoscopy be highlighted.
