METHODS: One hundred and sixty outpatients referred for diagnostic EGD were randomly allocated to 3 groups: conventional (C)-EGD (9.8 mm in diameter), transnasal (TN)-EGD and transoral (TO)-EGD (5.9 mm in diameter). Pre-EGD anxiety was measured using a 100-mm visual analogue scale (VAS). After EGD, patients and endoscopists completed a questionnaire on the pain, nausea, choking, overall discomfort, and quality of the examination either using VAS or answering some questions. The duration of EGD was timed. Blood oxygen saturation (SaO2) and heart rate (HR) were monitored during EGD. RESULTS: Twenty-one patients refused to participate in the study. The 3 groups were well-matched for age, gender, experience with EGD, and anxiety. EGD was completed in 91.1% (41/45), 97.5% (40/41), and 96.2% (51/53) of cases in TN-EGD, TO-EGD, and C-EGD groups, respectively. TN-EGD lasted longer (3.11 ± 1.60 min) than TO-EGD (2.25 ± 1.45 min) and C-EGD (2.49 ± 1.64 rain) (P 〈 0.05). The overall tolerance was higher (P 〈 0.05) and the overall discomfort was lower (P 〈 0.05) in TN-EGD group than in C-EGD group. EGD was tolerated "better than expected" in 73.2% of patients in TN-EGD group and 55% and 39.2% of patients in TO-EGD and C-EGD groups, respectively (P 〈 0.05). Endoscopy was tolerated "worst than expected" in 4.9% of patients in TN-EGD group and 17.5% and 23.5% of patients in TO- EGD and C-EGD groups, respectively (P 〈 0.05). TN-EGD caused mild epistaxis in one case, The ability to insuffiate air, wash the lens, and suction of the thin endoscope were lower than those of conventional instrument (P 〈 0,001), All biopsies performed were adequate for histological assessment. CONCLUSION: Diagnostic TN-EGD is better tolerated than C-EGD, Narrow-diameter endoscope has a level of diagnostic accuracy comparable to that of conventional gastroscope, even though some technical characteristics of these instruments should be improved, Transnasal EGD with narrow-diameter endoscope should be proposed to all patients undergoing diagnostic EGD.展开更多

METHODS: In 37 post-surgical patients, a stepwise approach was performed to reach normal papilla or enteral anastomoses of the biliary tract/pancreas. When conventional endoscopy failed, DBE-based ERCP was performed and standard parameters for DBE, ERCP and interventions were recorded. RESULTS: Push-enteroscopy (overall, 16 procedures) reached enteral anastomoses only in six out of 37 post-surgical patients (16.2%). DBE achieved a high rate of luminal access to the biliary tract in 23 of the remaining 31 patients (74.1%) and to the pancreatic duct (three patients). Among all DBE-based ERCPs (86 procedures), 21/23 patients (91.3%) were successfully treated. Interventions included ostium incision or papillotomy in 6/23 (26%) and 7/23 patients (30.4%), respectively. Biliary endoprosthesis insertion and regular exchange was achieved in 17/23 (73.9%) and 7/23 patients (30.4%), respectively. Furthermore, bile duct stone extraction as well as ostium and papillary dilation were performed in 5/23 (21.7%) and 3/23 patients (13.0%), respectively. Complications during DBE-based procedures were bleeding (1.1%), perforation (2.3%) and pancreatitis (2.3%), and minor complications occurred in up to 19.1%. CONCLUSION: The appropriate use of DBE yields a high rate of luminal access to papilla or enteral anastomoses in more than two-thirds of post-surgical patients, allowing important successful endoscopic therapeutic interventions.展开更多

For many years, technological challenges have made performing these procedures difficult. The "mother-baby" system and other various miniscopes have been developed, but routine use has been hampered due to complex setup, scope fragility and the time consuming, technically demanding nature of the procedure. Recently, the SpyGlass peroral cholangiopancreatoscopy system has shown early success at providing diagnostic information and therapeutic options. The clinical utility of intraductal endoscopy is broad. It allows better differentiation between benign and malignant processes by allowing direct visualization and targeted sampling of tissue. Therapeutic interventions, such as electrohydraulic lithotripsy (EHL), laser lithotripsy, photodynamic therapy, and argon plasma coagulation (APC), may also be performed as part of intraductal endoscopy. Intraductal endoscopy significantly increases the diagnostic and therapeutic yield of standard endoscopic retrograde cholangiography (ERCP), and as technology progresses, it is likely that its utilization will only increase. In this review of intraductal endoscopy, we describe in detail the various endoscopic platforms and their diagnostic and clinical applications.展开更多

During the first and last 3-mo eras(era 1 and 3), no HFNO was available, whereas it was an option during the second 3-mo era(era 2). The primary outcome was the percent utilization of GA vs deep sedation in each period. Secondary outcomes included oxygen saturation nadir during sedation between periods, as well as procedure duration, and anesthesia-only time between periods and for GA vs sedation cases respectively.RESULTS During the study period 238 ERCP or EUS cases were identified for analysis. Statistical testing was employed and a P < 0.050 was significant unless the Bonferroni correction for multiple comparisons was used. General anesthesia use was significantly lower in era 2 compared to era 1 with the same trend between era 2 and 3(P = 0.012 and 0.045 respectively). The oxygen saturation nadir during sedation was significantly higher in era 2 compared to era 3(P < 0.001) but not between eras 1 and 2(P = 0.028) or 1 and 3(P = 0.069). The procedure time within each era was significantly longer under GA compared to deep sedation(P ≤ 0.007) as was the anesthesia-only time(P ≤ 0.001).CONCLUSION High-flow nasal oxygen availability was associated with decreased GA utilization and improved oxygenation for ERCP and EUS during sedation.展开更多

METHODS:A strict literature search of studies comparing the yield of CE and EGD in patients diagnosed or suspected as having esophageal varices was conducted by both computer search and manual search.Data were extracted to estimate the pooled diagnostic sensitivity and specificity. RESULTS:There were seven studies appropriate for meta-analysis in our study,involving 446 patients. The pooled sensitivity and specificity of CE for detecting esophageal varices were 85.8%and 80.5%, respectively.In subgroup analysis,the pooled sensitivity and specificity were 82.7%and 54.8%in screened patients,and 87.3%and 84.7%in the screened/ patients under surveillance,respectively. CONCLUSION:CE appears to have acceptable sensitivity and specificity in detecting esophageal varices.However,data are insufficient to determine the accurate diagnostic value of CE in the screen/ surveillance of patients alone.展开更多
