Background/Aims: Propofol sedation for elderly patients during time-consuming endoscopic procedures is controversial. Therefore, we investigated the safety of using propofol in elderly patients during upper gastrointestinal therapeutic endoscopy. Methods: The medical records of 160 patients who underwent therapeutic endoscopic procedures under gastroenterologist- guided propofol sedation at a single institution were retrospectively reviewed. The subjects were divided into two groups: a younger group, patients <75 years old; and an elderly group, patients ≥75 years old. The two groups were compared with respect to the therapeutic regimen, circulatory dynamics, and presence/absence of discontinuation of propofol treatment. Results: Although the number of patients with liver dysfunction was higher in the elderly group, there were no other significant differences in the baseline characteristics, including the American Society of Anesthesiologists classification, between the elderly and younger groups. The average maintenance rate of continuous propofol infusion was lower in the elderly patients. No statistically significant differences were found in the occurrence of adverse events between the elderly and younger groups. None of the patients returned to a resedated state after the initial recovery from sedation. Conclusions: Gastroenterologist-guided propofol sedation in elderly patients can be safely achieved in the same manner as that in younger patients, even for timeconsuming upper gastrointestinal therapeutic endoscopic procedures.

Bowel habits affect the quality of life (QOL) of patients with functional gastrointestinal disorders. This study evaluated the effects of reduced form coenzyme Q 10 (ubiquinol) intake on defecation frequency and stool form in patients with daily abdominal symptoms. This was a single-center, prospective, double-blind, randomized control study. Forty-one patients who had the daily symptom of constipation or diarrhea were randomly assigned at a 1:1 ratio to receive either ubiquinol (150 mg/day) or placebo for 12 weeks. Patients completed a daily diary to collect information regarding their numbers of defecations and stool forms according to the Bristol Stool Form (BSF) Scale for 7 days at baseline and 12 weeks. QOL was assessed using the 36-item short-form (SF-36) at baseline and 12 weeks. Twenty-one patients were assigned to the ubiquinol group, and 20 were assigned to the placebo group. At 12 weeks, the mean defecation frequency, compared to baseline, significantly decreased in the ubiquinol group (−0.1 times/day, P = .034) and increased in the placebo group (+0.3 times/day, P = .004). There was no significant change in the 12-week BSF Scale score of the ubiquinol group (+0.2, P = .123), whereas that of the placebo group was increased (+0.5, P < .001). The 12-week general health perception SF-36 score was significantly increased in the ubiquinol group (+3.5, P = .045), whereas there was no significant difference in that score in the placebo group (+1.2, P = .178). In conclusion, taking ubiquinol for 12 weeks decreased defecation frequencies and increased the QOL score, suggesting that ubiquinol may change the bowel habits and improve QOL in patients with abdominal distress.

Diagnostic Ability of High-definition Imaging Using Ultraslim Endoscopes in Early Gastric Cancer
Sugita, Tomomi,Suzuki, Sho,Ichijima, Ryoji,Ogura, Kanako,Kusano, Chika,Ikehara, Hisatomo,Gotoda, Takuji,Moriyama, Mitsuhiko The Korean Gastric Cancer Association 2021 Journal of gastric cancer Vol.21 No.3
Purpose: It is unclear whether high-definition (HD) imaging improves visibility and diagnostic ability in early gastric cancer (EGC) compared with standard-definition (SD) imaging. We aimed to compare the diagnostic performance and visibility scores of HD and SD ultraslim endoscopes in EGC. Materials and Methods: We used HD and SD ultraslim endoscopes to obtain 60 images with similar compositions of gastric environments. Of the 60 images, 30 showed EGC (15 images for each modality) and 30 showed no EGC (15 images for each modality). Seventeen endoscopists evaluated the presence and location of the lesions in each image. Diagnostic ability was compared between modalities. The color difference between a lesion and the surrounding mucosa (ΔE) was measured and compared between the modalities. Results: The ability of HD to detect EGC was significantly higher than that of SD (accuracy: 80.8% vs. 71.6%, P=0.017; sensitivity: 94.9% vs. 76.5%, P<0.001; positive predictive value, 76.2% vs. 55.3%, P<0.001; and negative predictive value (NPV), 94.1% vs. 73.5%, P<0.001). The ability of HD to determine the horizontal extent of EGC was significantly higher than that of SD (accuracy: 71.0% vs. 57.8%, P=0.004; sensitivity: 75.3% vs. 49.0%, P<0.001; NPV, 72.9% vs. 55.9%, P<0.001; and area under the curve: 0.891 vs. 0.631, P=0.038). The mean ΔE was significantly higher for HD than for SD (10.3 vs. 5.9, P=0.011). Conclusions: The HD ultraslim endoscope showed a higher diagnostic performance in EGC than the SD endoscope because it provided good color contrast.
