Features of Endoscopy

15_30_01_01

“Endoscope” is a very fine tubular medical device with a built-in microcamera (please refer to the photo). It is inserted into the digestive system for monitoring the internal surface, as well as for diagnosis. It is also used for a procedure or a treatment by resecting the region with a resecting device attached at the distal end. Endoscope inserted from either mouth or nose into upper gastrointestinal tract including laryngopharynx, esophagus, stomach and duodenum, is commonly called “gastric camera,” while the one inserted from anus into lower gastrointestinal tract including small intestine, large intestine, colon and rectum is called “large intestinal endoscope (colonoscope).” Moreover, endoscope is used for obtaining images of organs outside of gastrointestinal tract, including bile duct and pancreas, for diagnoses and treatments. At the Division of Endoscopy, all the procedures performed by endoscopy are being provided.
Examination by endoscopy is not only useful for a case required to determine “whether it is a cancer or not,” but also for a case diagnosed so. It will help examine on how deep the tumor is located and how wide it is spreading, and will eventually help make optimal therapeutic plans.
What is being provided as treatments via endoscopy includes resections of polyps and early-staged cancers in gastrointestinal tract, and in the biliary and pancreatic field, bile excretion for biliary stricture, and gallstone removal, etc. The procedures won’t give patients physical impacts as heavily as surgeries, and at the same time, they can be done aiming at complete cures of cancers.

Features and Therapeutic Strategies of the Division at the SCC

The number of cases for diagnoses and treatments by endoscopy here is one of the biggest in Japan.

The Division of Endoscopy at the SCC has a good track record of cancer diagnoses and treatments by endoscopy. The number of endoscopic resections of gastric cancer here is always ranked among the top three in Japan, and the numbers of endoscopic resections in esophagus and large intestine, as well as the number of endoscopic procedures in the biliary and pancreatic field, are also ranked quite high. Based on ample experiences, we make diagnostic decisions and optimal therapeutic plans for safe and certain endoscopic treatments. That way, we keep on building up fine track record in this field of medicine.

We participate in clinical tests willingly, aiming at the further progress of medicine.

We are willing to participate in clinical tests for assuring diagnostic or therapeutic methods, even when they haven’t gained consensus in Japan yet. We are engaged in clinical tests in collaboration with other medical institutions nationwide, including a study conducted by JCOG (the Japan Clinical Oncology Group), as well as our own studies.

A Word from the Division Staff

Please do not hesitate to inquire the doctors and the nurses when you have any questions about examinations and treatments that you are scheduled to take.
