| 1 | Effect of music on patients undergoing outpatient colonoscopy显示文摘AIM: To evaluate the effect of relaxing music during colonoscopy under low-dose conscious sedation, on patient satisfaction, scope insertion time and procedure duration, medication doses, and the perceived adequacy of sedation and scope insertion difficulty on the part of the endoscopist. METHODS: One hundred and sixty-seven consecutive adult outpatients presenting for routine colonoscopy under low-dose conscious sedation were randomized to undergo their procedures either with music played during the procedure or no music played. RESULTS: There were no statistical differences between the two groups in terms of meperidine dose, midazolam dose, time to reach the cecum, total procedure time, endoscopist assessment of scope insertion difficulty, endoscopist assessment of adequacy of sedation, or the pain experience of the patients during their procedure. The music group did report significantly better overall procedure satisfaction as compared to the non music group on two of our three different scales. CONCLUSION: While music does not result in shortened procedure times, lower doses of sedative medications or perceived patient pain, the patients who have music playing during their procedures report modestly greater satisfaction with their procedures. | Matthew L Bechtold Rodney A Perez Srinivas R Puli John B Marshall | 2006 | World Journal of Gastroenterology2006，12，45： | 8 |
| 2 | Bravo (wireless) ambulatory esophageal pH monitoring: How do day 1 and day 2 results compare?显示文摘AIM: To investigate if differences exist for patients’ gastroesophageal reflux as measured by the Bravo ambulatory esophageal pH system between d 1 and d 2. METHODS: A retrospective study of 27 consecutive adult patients who underwent Bravo esophageal pH monitoring was performed. Patients underwent EGD under Ⅳ conscious sedation prior to Bravo placement. Acid reflux variables and symptom scores for d 1 were compared to d 2. RESULTS: The mean doses of fentanyl and midazolam were 90.4 μg and 7.2 mg, respectively. D 1 results were significantly more elevated than d 2 with respect to total time pH < 4, upright position reflux, and mean number of long refluxes. No statistical difference was noted between the two days for supine position reflux, number of refluxes, duration of longest reflux, episodes of heartburn, and symptom score. CONCLUSION: Patients undergoing Bravo esophageal pH monitoring in association with EGD and moderate conscious sedation experience significantly more acid reflux on d 1 compared to d 2. The Ⅳ sedation may be responsible for the increased reflux on d 1. Performed this way, 48-h Bravo results may not be entirely representative of the patients’ true GE reflux profile. | Matthew L Bechtold Jason-Scott L Holly Klaus Thaler John B Marshall | 2007 | World Journal of Gastroenterology2007，13，30： | 4 |
| 3 | Endoscopic ultrasound-guided fiducial marker placement in pancreatic cancer:A systematic review and meta-analysis显示文摘BACKGROUND Pancreatic cancer(PC)mortality remains high despite advances in therapy.Combination chemoradiotherapy offers modest survival benefit over monotherapy with either.Fiducial markers serve as needed landmarks for imageguided radiotherapy(IGRT).Traditionally,these markers were placed surgically or percutaneously with limitations of each.Endoscopic ultrasound-guided placement overcomes these limitations.AIM To evaluate the safety,efficacy,and feasibility of endoscopic ultrasound(EUS)-guided fiducial placement for PC undergoing IGRT.METHODS Articles were searched in MEDLINE,PubMed,and Ovid journals.Pooling was conducted by fixed and random effects models.Heterogeneity was assessed using Cochran’s Q test based upon inverse variance weights.RESULTS Initial search identified 1024 reference articles for EUS-guided fiducial placement in PC.Of these,261 relevant articles were reviewed.Data was extracted from 11 studies(n=820)meeting inclusion criteria.Pooled proportion of successful placement was 96.27%(95%CI:95.35-97.81)with fiducial migration rates low at 4.33%(95%CI:2.45-6.71).Adverse event rates remained low,with overall pooled proportion of 4.85%(95%CI:3.04-7.03).CONCLUSION EUS-guided placement of fiducial markers for IGRT of PC is safe,feasible,and efficacious.The ability to target deep structures under direct visualization while remaining minimally invasive are added benefits.Moreover,the ability to perform fine needle aspiration or celiac plexus neurolysis add value and increase patient-care efficiency.Whether EUS-guided fiducial placement improves outcomes in IGRT or offers any mortality benefits over traditional placement remains unknown and future studies are needed. | Jaymon B Patel Vakya Revanur David G Forcione Matthew L Bechtold Srinivas R Puli | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，8： | 2 |
