There is still a big difference between a capsule gastroscope and a regular gastroscope. Because this small capsule passes through the esophagus very fast, sometimes part of the esophagus can not be seen clearly. In addition, since the stomach cavity is relatively large, the capsule will pass through the cavity relatively fast, and it will miss some corners of the stomach or the bottom of the stomach. But it can be seen relatively complete and comprehensive through the small intestine, because the intestinal cavity of the small intestine is relatively small, the chance of missing the diagnosis will be relatively small, so the capsule gastroscope is mainly used to look at the small intestine. There is another kind of controlled capsule gastroscope, which can control the capsule in the body by remote control outside the body, so that every corner of the stomach cavity can be seen clearly. The normal stomach is mainly a tube inserted through the mouth or nostril, respectively, transoral gastroscopy and transnasal gastroscopy. It is a tube that is inserted into the stomach and then the stomach, as well as the duodenal bulb and the descending duodenum are looked at. This type of gastroscopy is relatively more laborious, but it looks at the stomach cavity and gives a more comprehensive view. It is also possible to take a biopsy for pathological examination if abnormalities are found. There is still a big difference between the cost of capsule gastroscopy and regular gastroscopy. The cost of a capsule gastroscopy is about$4000+ at a tertiary care hospital, while a regular gastroscopy can be done for$300+. So if you want to look at the esophagus, stomach, duodenum bulb, and duodenum descending, it is recommended to do a general gastroscopy, and if the purpose is to look at the small intestine, then you can consider a capsule gastroscopy.
