Do You Know Anything About Endoscopic Ultrasound
Nov 07, 2022
Hyperendoscopy is to place a small ultrasonic probe in the front of the gastroscope, so that we can observe the abnormal conditions on the surface of the stomach through the gastroscope on the one hand, and the conditions around the stomach wall or the stomach wall can be observed by ultrasound, just like installing a fluoroscopic eye, through the stomach wall to see the conditions around the stomach.
So what do we see with the ultrasound gastroscope? First of all, you can see gastric submucosal bumps, you say, we do gastroscope found there is a similar to the polyps in the stomach, we don't know how deep it is, however, comes from which layer of the stomach, we can do it, just by ultrasonic gastroscopy if we by endoscopic ultrasonography found it comes from the first floor of the stomach, then we can make sure it is polyp, And we found similar to slide under gastroscope fibroids or apophysis lesions of stromal tumor, we found it comes from the stomach through endoscopic ultrasonography of the second or the fourth floor, can clear, with the popularity of gastroscope, early cancer found that more and more, we'd like to know it can be removed through gastroscope, that is more from ultrasonic gastroscopy, no more than the submucosal lesions, Can be safely removed by endoscope.
The role of large gastroscope is not limited to this. Through the examination of digestive tract cancer, it can accurately distinguish the depth of tumor invasion, the invasion of surrounding organs, and the lymph node metastasis, namely TNM staging, which is of great significance for the surgical resection of tumors.
Ultrasound gastroscope inspection as close to the wall of the stomach, for pancreas showed good after gastric wall, and conventional ultrasound in vitro because influenced by gastrointestinal gas, etc, the pancreas show is always unsatisfactory, 2-3 mm ultrasonic gastroscopy can even find the size of the lesions, for the CT, MRI and ultrasound are hard to do, in addition, endoscopic ultrasonography and fine needle biopsy can be performed, This can directly characterize the pathological tissue and clarify the nature of the lesion.
The distal common bile duct and ampulla have always been close to a blind area for in vitro ultrasound, but endoscopic ultrasound can easily perform this examination through the duodenum, providing a clear direction for ERCP or surgical treatment.
Patients with advanced tumors usually have poor quality of life due to tumor pain, etc., and we can improve the quality of life of patients through endoscopic ultrasound guided abdominal nerve plexus treatment.
Pseudocysts of the pancreas are traditionally operated on by surgery, which is highly traumatic and has a high chance of recurrence after surgery. However, endoscopic ultrasound, guided by the ultrasound probe, can perform puncture and drainage, which has small trauma, low cost, extremely low postoperative complications and rarely recurrence.
The use of endoscopic ultrasound is not limited to this, and more and more applications have been developed and are being developed.
