Background: One-day low-residue diet (LRD) is recommended before colonoscopy, but only three single-center trials compared the 1-day versus 3-day LRD. The aim of this multicenter study was to compare the impact of a 3-day versus 1-day LRD on its ability to adequately and successfully prepare the bowel of outpatients that require a colonoscopy. The outpatients' tolerance and adherence to the LRD were also considered. Methods: Consecutive outpatients were randomized to 1-day versus 3-day LRD at three open-access endoscopy units. The primary endpoint consisted of the proportion of patients with a satisfactory degree of bowel cleanliness (Score 2–3 on the Boston Bowel Preparation Scale [BBPS] in each segment). Secondary endpoints were patients' tolerance and adherence to the prescribed diet evaluated by a standardized questionnaire. Results: 289 patients were included in the study (1-day LRD arm = 143, 3-day LRD arm = 146). BBPS ≥2 was not significantly different in the two dietary regimens in any of the three colonic segments (71% vs. 72%, p = 0.9). The percentage of patients with incomplete preparation was similar in the two arms (9% vs. 9%; p = 1.0). No significant differences were found among colonoscopy findings in terms of abnormalities (81% vs. 84%, p = 0.8). Both groups scored similarly in overall tolerance to LRD (48% vs. 49%, p = 1.0) and also in whether they would have adopted a different dietary regimen (p = 0.3). Conclusion: Our multicenter randomized study confirmed that optimal bowel cleansing is reached through a 1-day LRD. [ABSTRACT FROM AUTHOR]

Introduction: Advances in endoscopy and open-access systems led to an increase in endoscopic procedures. However, overuse of endoscopy has been consistently reported. This study aims to assess the appropriateness of esophagogastroduodenoscopy (EGD) and colonoscopy referral in the private and public setting. Patients and Methods: We conducted a prospective, multicenter study at 2 public and 5 private endoscopy units. Patients scheduled for elective EGD or colonoscopy were enrolled. Clinical data and endoscopy findings were recorded. Appropriateness of endoscopy was defined according to the American Society for Gastrointestinal Endoscopy guidelines (for EGD) and the European Panel on Appropriateness of Gastrointestinal Endoscopy II (for colonoscopy). Results: Regarding EGD: 215 patients enrolled (43.7% were males) with a mean age of 61.0 ± 15.1 years; 54.0% (n = 116) were in public hospitals. Referral by a gastroenterologist was made for 34.9% (n = 75). Appropriate indications were made for 62.3% (n = 134): 42.4% in private versus 79.3% in public endoscopy units (odds ratio [OR] 5.20; 95% confidence interval [CI] 2.85–9.49; p < 0.01). Rate of appropriate EGD was 74.7% for gastroenterologist referral and 56.1% for other specialties (OR 2.31; 95% CI 1.24–4.28; p < 0.01). Diagnostic yield for relevant findings was 47.9%. No association between indication appropriateness, gastroenterologist referral, and relevant endoscopic findings was found. Regarding colonoscopy: 287 patients enrolled (49.1% were males) with a mean age of 60.4 ± 14.4 years; 48.1% (n = 138) were in public hospitals. Referral by a gastroenterologist was made for 20.6% (n = 59). Appropriate indications were made for 70.0% (n = 201): 53.0% in private vs. 88.4% in public endoscopy units (OR 6.75; 95% CI 3.66–12.47; p < 0.01). Diagnostic yield was 57.1%. Relevant endoscopic diagnosis was associated with indication: 63.2% in the appropriate vs. 43.0% in the nonappropriate indication group (p < 0.05). Discussion: A significant percentage of endoscopies, mainly in the private setting, were performed without an appropriate indication. This influenced the diagnostic yield. The use of adequate criteria is fundamental for the rational use of an open-access system.

Background: Open-access oesophagogastroduodenoscopy (OAO) is defined as the performance of oesophagogastroduodenoscopy (OGD) requested by referring physicians without a prior specialist consultation. With the increasing demand for specialist appointments, the use of OAO has helped to reduce healthcare utilization by decreasing prior clinic visits. This also allows endoscopies to be scheduled and performed earlier. This study aims to evaluate our experience in providing OAO services to patients with non-alarming dyspepsia symptoms under the age of 60., Methods: The records of patients scheduled for OAO from January 2019 to December 2022 at Singapore General Hospital (SGH) Department of Gastroenterology were analyzed., Results: Five hundred sixty-nine patients were scheduled for OAO, and 436 patients underwent the procedure. The mean age of patients was 45.7 (SD=10.9) years old. Thirty-six percent were males, and there were 80.8% Chinese, 5.3% Malay, 8.6% Indian, and 5.3% others. The median waiting time for endoscopy was 23 days (IQR 16-36), and no major adverse events were reported. Over half of the endoscopies were unremarkable (n=231, 53%). There were 25 (5.7%) patients with major findings; three had upper gastrointestinal adenocarcinoma (one oesophageal and two gastric), one had oesophageal varices, and 21 had peptic ulcer disease (10 gastric and 11 duodenal ulcers). A rapid urease test was conducted on 409 patients, and 55 (13.4%) were positive., Conclusion: OAO is a safe and effective strategy for providing timely diagnostic OGD to normal-risk patients at our center. Primary care physicians are encouraged to refer non-alarming dyspepsia symptoms patients under 60 years for OAO over the conventional route., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Tan et al.)

Background and Aims: Open-access scheduling is highly utilized for facilitating generally low-risk endoscopies. Preprocedural screening addresses sedation requirements; however, procedural safety may be compromised if screening is inaccurate. We sought to determine the reliability of our open-access scheduling system for appropriate use of conscious sedation., Methods: We prospectively and consecutively enrolled outpatient procedures booked at an academic center by open-access using screening after in-office gastroenterology (GI) consultation. We collected the cases inappropriately booked for conscious sedation and compared the characteristics for significant differences., Results: A total of 8063 outpatients were scheduled for procedures with conscious sedation, and 5959 were booked with open-access. Only 78 patients (0.97%, 78/8063) were identified as subsequently needing anesthesiologist-assisted sedation; 44 (56.4%, 44/78) were booked through open-access, of which chronic opioid (47.7%, 21/44) or benzodiazepine use (34.1%, 15/44) were the most common reasons for needing anesthesiologist-assisted sedation. Patients on chronic benzodiazepines required more midazolam than those not on chronic benzodiazepines (P = .03) of those patients who underwent conscious sedation. Similarly, patients with chronic opioid use required more fentanyl than those without chronic opioid use (P = .04). Advanced liver disease and alcohol use were common reasons for patients being booked after in-office consultation and were significantly higher than those booked with open-access (both P < .01)., Conclusions: We observed that the majority of patients can be triaged for conscious sedation using a multi-tiered screening process. Importantly, few patients (<1.0%) were inappropriately booked for conscious sedation. The most common reasons for considering anesthesiologist-assisted sedation were chronic opioid, benzodiazepine and/or alcohol use and advanced liver disease. This suggests that these entities could be included in screening processes for open-access scheduling., (© The Author(s) 2016.

Endoscopy constitutes a wide range of procedures with many indications. Esophagogastroduodenoscopy, colonoscopy, endoscopic retrograde cholangiopancreatography, endoscopic ultrasonography, and enteroscopy comprise the most commonly performed procedures. These examinations all carry risk to the patient, and incumbent in this is some legal risk with regard to how the procedure is conducted, decisions made based on the intraprocedure findings, and the postprocedure results, in addition to events that occur following the procedure. This article provides an overview of consent and complications of endoscopy., (Copyright © 2015 Elsevier Inc. All rights reserved.)

The current practice of open-access endoscopy allows primary care and other non-gastroenterology physicians to directly refer patients for routine gastrointestinal endoscopic procedures. Open-access endoscopy is considered to be more cost-effective and time efficient than the traditional practice of referring patients for preprocedural consultation with a gastrointestinal endoscopist. Several studies have evaluated the performance of endoscopic procedures in an open-access environment and the utility of structured referral mechanisms to ensure safe and appropriately indicated procedures. This review focuses on 4 common preprocedural issues in gastrointestinal endoscopy encountered by primary care physicians: management of anticoagulation and antiplatelet therapy, indication for prophylactic antibiotic drug therapy, need for anesthesia-assisted sedation, and management of poor bowel preparation. We summarize the current guidelines that address these 4 common preprocedural issues to facilitate safe and clinically appropriate procedures in open-access endoscopy., (Copyright © 2013 Mayo Foundation for Medical Education and Research.
