There has been a great advancement in the field of advanced diagnostic endoscopy and therapeutic endoscopy. However, endoscopic education for the beginners has been widely abandoned. As a result, a great proportion of endoscopic examinations are performed by suboptimally educated endoscopists. The volume of endoscopic examination is huge in Korea, so the quality control of the endoscopists is a great impact on the quality of the whole healthcase system.

At Samsung Medical Center, we have developed a basic endoscopic education course. The 3-month full-time introductory endoscopy training course is composed of following components. Most of the education materials are available on-line at http://endotoday.com/endotoday/endoscopy_training_2018.html.

  1. Endoscopy box simulator training (4 hours for upper endoscopy and 4 hours for lower endoscopy)
  2. Staff lectures (12 hours)
  3. Endoscopic findings description exercise (70 cases)
  4. Textbook reading (12 hours)
  5. Topic presentation (8 hours)
  6. Endoscopy-related conferences (3 hours per week)
  7. E-mail learning (daily on-line learning (http://endotoday.com), usually 20 minutes per day)
  8. Observation at endoscopy unit (15 hours per week for 3 months)

The philosophy underlying our basic training course is that the knowledge is more important than the technique. You should have enough knowledge and desciption skills before starting technical training. It usually requires extensive training for 3 months before starting the first endoscopic examinations for the real patients.

Most of the education resources are available on-line, but the most import and unique component of our basic training course is the box simulator training with professors and the description exercise checked by the most experienced endoscopy teachers. I hope the model developed by our endoscopy unit is useful for the endoscopy beginners.

The catheter used in our preliminary study had four sensors arrayed circumferentially at each of two levels. In our main study, the pH catheter had eight sensors (white arrows) arrayed circumferentially at the same level as the catheter. This catheter had a blue line on channel 1 located at the 6 o¡¯clock position, and the eight sensors were arranged counterclockwise from that position

Distribution of the direction of s-BEA in (a) SSBE, (b) LSBE, and (c) all cases of Barrett¡¯s esophagus.

A s-BEA case located at the 0-3 o¡¯clock position in the lower esophagus. MTD-A and MTD-NA were detected by sensor 4 in the 0-3 o¡¯clock position, and therefore this case was coincidental with acid and non-acid reflux.

A s-BEA case located at the 9-10 o¡¯clock position in BE. MTD-A was detected by sensors 5-7 in the 9-0 o¡¯clock position, and MTD-NA was detected by sensors 6-8 in the 8-10 o¡¯clock position. Therefore this case was coincidental with both acid and non-acid reflux.
