Can gastric endoscopy with biopsy detect gastric nodules?

Generally, gastric nodules can be detected through endoscopic biopsy. The detailed analysis is as follows:

Endoscopic biopsy involves inserting an endoscope into the stomach to directly observe the condition of the gastric mucosa and, when necessary, taking a small tissue sample for pathological analysis. During the procedure, the physician first conducts a comprehensive examination of the gastric mucosa using the endoscope to identify any potential abnormal areas. When a gastric nodule is detected, the physician makes a preliminary assessment based on characteristics such as its morphology, size, and location, and determines whether further biopsy is necessary.

If a biopsy is required, the physician uses biopsy forceps to collect a small piece of tissue from the nodule. This tissue sample is then sent to the pathology department for processing, including slicing and staining, after which the cellular morphology and tissue structure are examined under a microscope to determine the nature of the nodule. Through endoscopic biopsy, physicians can confirm whether a gastric nodule is benign or malignant, and assess whether there is a risk of malignant transformation.

Although endoscopic biopsy is a highly accurate diagnostic method, not all gastric nodules require biopsy. Additionally, prior to undergoing endoscopic biopsy, patients should fully understand the risks and precautions associated with the procedure and adequately prepare and cooperate under the guidance of a physician.
