Background/Aims: The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The effcacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the effcacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the effcacy between EAC and CAC in trainees. Methods: This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups. Results: The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group. Conclusions Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees.

We treated dry eyes and eyestrains successfully with electrothermo-acupuncture and Kampo medicine. The case was a 41-year-old woman who was treated with a few eye drops. She came to our hospital to receive Kampo medicine because her photophobia and eye pain got worse. After taking shimbuto, her complaint got better with improving physical fatigue. Electrothermo-acupuncture was effective for photophobia and eye pain promptly and remarkably. After we added kihito to her, she did not need to use eye drops with improving bloody urine and sleeplessness. Photophobia and eye-ache are thought to be related to the trigeminal nerve system. In this case, we consider that the point of application of electrothermo-acupuncture is the trigeminal nerve system. At the same time, “rikan” and “hikyo” might be involved in this case with the general malaise of eye.
