Abstract

Background Bowel ultrasonography (BUS) is emerging as a promising noninvasive tool for assessing disease activity in inflammatory bowel disease (IBD) patients. We evaluated the diagnostic accuracy of BUS in IBD patients against the gold standard diagnostic method, standard colonoscopy. Methods Major databases were searched from inception to May 2023 for studies on BUS diagnostic accuracy in IBD. Outcomes of interest were pooled sensitivity, specificity, positive (PPV), and negative (NPV) predictive values. Endoscopic confirmation served as ground truth. Standard meta-analysis methods with a random-effects model and I2 statistics were applied. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Results Twenty studies (1094 patients) were included in the final analysis. The majority (75%) of studies considered bowel wall thickness >3 mm as abnormal. Endoscopic evaluation was performed between days 3 and 180. The pooled diagnostic accuracy of BUS in IBD was 66% (95% confidence interval [CI] 58-72%; I2=78%), sensitivity was 88.6% (95%CI 85-91%; I2=77%), and specificity 86% (95%CI 81-90%; I2=95%). PPV and NPV were 94% (95%CI 93-96%; I2=25%) and 74% (95%CI 66-80%; I2=95%), respectively. On subgroup analysis, small-intestine contrastenhanced ultrasonography (SICUS) demonstrated high sensitivity (97%, 95%CI 91-99%; I2=83%), whereas BUS exhibited high specificity (94%, 95%CI 92-96%; I2=0%) and NPV (76%, 95%CI 68-83%; I2=80.9%). Meta-regression revealed a significant relation between side-to-side anastomosis and BUS specificity (P=0.02) and NPV (P=0.004). Conclusion The high diagnostic accuracy of BUS in detecting bowel wall inflammation suggests utilizing regular BUS as the primary modality, with subsequent consideration of SICUS if clinically warranted.

Abstract

Background and Aims: Several methods with variable efficacy have been proposed for difficult biliary cannulation in ERCP. We assessed the comparative efficacy of different strategies for difficult biliary cannulation through a network meta-analysis combining direct and indirect treatment comparisons. Methods: We identified 17 randomized controlled trials (2015 patients) that compared the efficacy of different adjunctive methods for difficult biliary cannulation (needle-knife techniques, pancreatic guidewire-assisted technique, pancreatic-assisted technique, and transpancreatic sphincterotomy) either with each other or with persistence with the standard cannulation techniques. The success rate of biliary cannulation and the incidence of post-ERCP pancreatitis (PEP) were the outcomes of interest. We performed pairwise and network meta-analysis for all treatments and used Grading of Recommendations Assessment, Development and Evaluation criteria to appraise quality of evidence. Results: Low-quality evidence supported the use of transpancreatic sphincterotomy over persistence with standard cannulation techniques (risk ratio [RR], 1.29; 95% confidence interval [CI], 1.05-1.59) and over any other adjunctive intervention (RR, 1.21 [95% CI, 1.01-1.44] vs pancreatic guidewire-assisted technique, RR, 1.19 [95% CI, 1.01-1.43] vs early needle-knife techniques, RR, 1.47 [95% CI, 1.03-2.10] vs pancreatic stent-assisted technique) for increasing the success rate of biliary cannulation. No other significant results were observed in any other comparisons. Based on the network model, transpancreatic sphincterotomy (P-score, .97) followed by early needle-knife techniques (P-score, .62) were ranked highest in terms of increasing the success rate of biliary cannulation. Early needle-knife techniques outperformed persistence with standard cannulation techniques in terms of decreasing PEP rate (RR, .61; 95% CI, .37-1.00), whereas both early needle-knife techniques and transpancreatic sphincterotomy led to lower PEP rates as compared with pancreatic guidewire-assisted technique (RR, .49 [95% CI, .23-.99] and .53 [95% CI, .30-.92], respectively). Conclusions: Transpancreatic sphincterotomy increases the success rate of biliary cannulation as compared with persistence with the standard cannulation techniques. Early needle-knife techniques and transpancreatic sphincterotomy are superior to other interventions in decreasing PEP rates and should be considered in patients with difficult cannulation.
