Clinical Endoscopy最新文献

Upper gastrointestinal endoscopy is commonly performed worldwide and is the gold standard for most upper gastrointestinal tract diseases, particularly cancer. This review will use gastric cancer as an example to tackle how providers can improve the quality of endoscopy being delivered to reduce the missing rate, which may reach up to 10% of cases. In brief, endoscopists must consider pre-, intra-, and post-procedural attitudes to achieve this purpose. "Preparing or planning endoscopy," cancer as a possible diagnosis in all procedures should be thought. Fasting of patients and the use of mucosal cleaning solutions help ensure mucosal cleansing, while planned sedation increases comfort. During endoscopy, taking time for complete inspection and photodocumentation to assure completeness. Importantly, training and knowledge of cancer (superficial) endoscopic features, particularly using advanced imaging technologies, are of paramount importance, as they are regular post-endoscopy audits of practice that positively impact quality. Finally, human-machine interaction through artificial intelligence has been shown to improve photodocumentation, detection, and auditing, and it may well assure a more homogenous service, particularly among low-performing deliverers.

Colonoscopy is the primary tool for colorectal cancer screening. High-quality colonoscopy is crucial for the detection of precancerous adenomas; however, the adenoma detection rate varies depending on the skill and experience of the endoscopist. Computer-aided quality assessment (CAQ) uses artificial intelligence (AI) technology to evaluate the quality of colonoscopy examinations. It plays an important role in reducing variations in examination quality and obtaining high-quality colonoscopic images. In this review, we focus specifically on the speedometer, effective withdrawal time, fold examination quality, bowel preparation quality assessment, and cecal intubation with CAQ systems and discuss the role and effectiveness of these systems. CAQ systems are expected to contribute to increase in adenoma detection rates, improvement in endoscopist skills, and standardization of examination quality. However, challenges such as variability in AI performance across different clinical settings and potential overreliance on automated prompts remain key limitations.

Background: Screening colonoscopies often do not include terminal ileum assessment. In this study, we examined how often endoscopists assessed the terminal ileum during screening colonoscopy, how it influenced the procedure time and patient comfort, and whether it revealed pathological findings.

Methods: We retrospectively analyzed the screening colonoscopy examinations performed in our department between 2017 and 2021. We retrieved the procedure duration (minutes), patient age and sex, pain scale, and screening colonoscopy results.

Results: A total of 2,449 screening colonoscopy examinations were performed between 2017 and 2021. The patients were classified into one of two groups: the cecum reached or the terminal ileum intubated. These two groups did not significantly differ in sex or reported pain score, while the patients were significantly younger (55.2±6.5 vs. 56.2±6 years, p=0.015) and the colonoscopy duration was longer (22.8±9.8 vs. 18±10.5 min, p<0.001) in the terminal ileum group. Pathological conditions (nonspecific inflammatory lesions) in the small intestine were reported in 5/297 patients.

Conclusions: Small intestine intubation was associated with a significantly longer colonoscopy duration and revealed pathological conditions of no apparent clinical significance.

Chronic pancreatitis (CP), a progressive inflammatory disease that results in irreversible pancreatic damage, is often complicated by ductal strictures and debilitating pain. Fully covered self-expandable metal stents (FCSEMS) have emerged as significant innovations in the endoscopic management of refractory pancreatic duct strictures. This review synthesizes recent evidence highlighting the benefits and limitations of FCSEMS, such as superior patency, reduced need for reinterventions, and effective symptom relief compared to traditional plastic stents, alongside risks, such as stent migration and de novo strictures. A comparison with plastic stents and an algorithm for pancreatic duct stricture management are provided. Regional variations in clinical guidelines from the United States, Europe, Japan, and Korea reflect diverse approaches to integrating FCSEMS into practice. Emerging innovations in stent technology are promising for improving CP management outcomes.

Background: Propofol is the most effective sedative for colonoscopy; however, opioids do have several adverse effects that need to be discussed. The objective of this study was to compare the ease of colonoscopy during propofol-based sedation with and without fentanyl, while closely monitoring ventilatory data and the safety of the procedure.

Methods: This prospective single-center trial randomized 50 patients who underwent minor colonoscopies. The propofol group received sedation exclusively via propofol, whereas the propofol+fentanyl group was premedicated with 1 µg/kg fentanyl. Patients were monitored using a bioimpedance ventilatory monitor, and both the patients and endoscopists were questioned regarding their level of satisfaction.

Results: The endoscopists reported a higher level of ease with the colonoscopy procedure (mean on a 5-point scale, 1.2 vs. 1.72; p=0.028) and the overall patient satisfaction score was higher (1.15 vs. 1.28, p=0.026) in the propofol+fentanyl group. No significant differences were observed in the ventilatory parameters between the groups. No major adverse events were reported in any of the groups.

Conclusions: The inclusion of fentanyl leads to enhanced levels of satisfaction for both the endoscopist and the patient, without any impact on ventilation and safety. The use of bioimpedance monitoring of ventilation during colonoscopy is a suitable approach that may enhance the safety of procedural sedation.
