RESUMO
Background: Endoscopic retrograde cholangiopancreatography (ERCP) is an essential endoscopic therapeutic modality for biliary and pancreatic diseases. Needle-knife fistulotomy (NKF) and papillotomy (NKP) are the two most commonly used rescue techniques for patients with difficult biliary cannulation. However, there remains a need for comparative studies on these approaches to inform clinical decision-making. This meta-analysis aimed to evaluate the efficacy and safety of NKF compared to NKP as a rescue technique in difficult biliary cannulation after failed conventional ERCP. Methods: We searched PubMed, Scopus, Embase, and Web of Science databases through November 2023 to include all studies that directly compared the outcomes of NKF with NKP in difficult biliary cannulation. Single-arm studies were excluded. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) for dichotomous data related to clinical events were calculated using the Mantel-Haenszel method within a random-effect model. The primary outcome was the biliary cannulation success rate. Results: Four studies with 823 patients (n = 376 NKF vs. n = 447 NKP) were included in our analysis. There was no significant difference between the two groups in biliary cannulation success rate (91.7% vs. 86.9%, respectively; OR = 1.54, 95% CI: 0.21 - 2.49, P = 0.14; I2 = 0%). However, the overall rate of adverse events was significantly lower in the NKF group than in the NKP group (OR = 0.46, 95% CI: 0.25 - 0.84, P = 0.01). Pancreatitis (OR = 0.23, 95% CI: 0.05 - 1.11, P = 0.07) and bleeding (OR = 1.43, 95% CI: 0.59 - 3.46, P = 0.42) were similar between the two groups. No significant differences in cholangitis, cholecystitis, perforation, or mortality were observed. Conclusions: Our meta-analysis indicates comparable success rates in comparing NKF and NKP techniques for difficult biliary cannulation after failed conventional ERCP cannulation. Notably, the NKF technique significantly reduces overall adverse events compared to NKP, suggesting that NKF may be preferable due to its favorable safety profile. Additional randomized controlled trials (RCTs) are warranted to evaluate the interval benefit of an NKF technique.
RESUMO
Background/Objectives: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) has emerged as an alternative option for biliary drainage in cases of failed endoscopic retrograde cholangiopancreatography (ERCP). Limited data exist on the safety and efficacy of EUS-HGS. In this comprehensive meta-analysis, we aim to study the safety and efficacy of EUS-HGS in cases of failed conventional ERCP. Methods: Embase, PubMed, and Web of Science databases were searched to include all studies that evaluated the efficacy and safety of EUS-HGS. Using the random effect model, the pooled weight-adjusted event rate estimate for clinical outcomes in each group were calculated with 95% confidence intervals (CIs). The primary outcomes were technical and clinical success rates. Secondary outcomes included overall adverse events (AEs), rates of recurrent biliary obstruction (RBO), and rates or re-intervention. Results: Our analysis included 70 studies, with a total of 3527 patients. The pooled technical and clinical success rates for EUS-HGS were 98.1% ([95% CI, 97.5-98.7]; I2 = 40%) and 98.1% ([95% CI, 97.5-98.7]; I2 = 40%), respectively. The pooled incidence rate of AEs with EUS-HGS was 14.9% (95% CI, 12.7-17.1), with bile leakage being the most common (2.4% [95% CI, 1.7-3.2]). The pooled incidence of RBO was 15.8% [95% CI, 12.2-19.4], with a high success rate for re-intervention (97.5% [95% CI, 94.7-100]). Conclusions: Our analysis showed high technical and clinical success rates of EUS-HGS, making it a feasible and effective alternative to ERCP. The ongoing development of dedicated devices and techniques is expected to make EUS-HGS more accessible and safer for patients in need of biliary drainage.
RESUMO
BACKGROUND AND AIMS: Biliary drainage is vital in managing malignant biliary obstruction (MBO). Suprapapillary stenting has emerged as a viable alternative to transpapillary stenting and is performed using inside plastic (iPS) or metal stents (iMS). This meta-analysis aims to evaluate the outcomes of suprapapillary stent placement for MBO. METHODS: The Embase, PubMed, and Web of Science databases were systematically searched to include all studies published before September 31, 2023, that reported on the outcomes of suprapapillary stents placed for MBO. Using the random-effect model, the pooled, weight-adjusted event rate estimate for the clinical outcomes was calculated with 95% confidence intervals (CIs). RESULTS: Twenty-eight studies were included, with a total of 1401 patients. The pooled clinical success rate was 98.9%. A subgroup analysis yielded non-significant differences between the iPS and iMS groups (99.3% vs. 98.6%, respectively; P = 0.44). The pooled incidence rate of adverse events (AE) with suprapapillary stents was 9.5%. In a subgroup analysis, the incidence of AEs with iPS was 10.7% compared to 9% in the iMS group without a statistical difference (P = 0.32). The most common adverse event was cholangitis (2.2%), followed by pancreatitis (1.1%), cholecystitis (0.5%), and bleeding (0.12%). CONCLUSION: When technically feasible, suprapapillary stenting for MBO is a viable endoscopic option with a high clinical success rate and acceptable adverse event rates. Both iPS and iMS exhibit similar efficacy.

BACKGROUND AND AIM: Luminal strictures, common in inflammatory bowel disease (IBD), especially Crohn's disease (CD), are typically treated with endoscopic balloon dilatation (EBD). The newer endoscopic stricturotomy (ESt) approach shows promise, but data is limited. This systematic review and meta-analysis assess the effectiveness and safety of ESt in IBD-related strictures. METHODS: A comprehensive literature search was conducted until November 2023 for studies assessing ESt efficacy and safety in IBD. Primary outcomes were clinical and technical success, with secondary endpoints covering adverse events, subsequent stricture surgery, additional endoscopic treatments (ESt or EBD), medication escalation, disease-related emergency department visits, and hospitalization post-ESt. Technical success was defined as passing the scope through the stricture, and clinical success was defined as symptom improvement. Single-arm meta-analysis (CMA version 3) calculated the event rate per patient with a 95% confidence interval (CI). Heterogeneity was evaluated using I2. RESULTS: Nine studies were included, involving 640 ESt procedures on 287 IBD patients (169 CD, 118 ulcerative colitis). Of these, 53.3% were men, with a mean age of 43.3 ± 14.3 years and a mean stricture length of 1.68 ± 0.84 cm. The technical success rate was 96.4% (95% CI 92.5-98.3, p-value < 0.0001), and the clinical success rate was 62% (95% CI 52.2-70.9, p-value = 0.017, I2 = 34.670). The bleeding rate was 10.5% per patient, and the perforation rate was 3.5%. After an average follow-up of 0.95 ± 1.1 years, 16.4% required surgery for strictures post-ESt, while 44.2% needed additional endoscopic treatment. The medication escalation rate after ESt was 14.7%. The disease-related emergency department visit rate was 14.7%, and the disease-related hospitalization rate post-procedure was 21.3%. CONCLUSION: Our analysis shows that ESt is safe and effective for managing IBD-related strictures, making it a valuable addition to the armamentarium of endoscopists. Formal training efforts should focus on ensuring its widespread adoption.
RESUMO
Background: Delirium is prevalent in elderly patients, linked to elevated mortality rates, heightened healthcare resource use, and caregiver burden. Inflammatory bowel disease (IBD) poses various delirium risk factors, yet the impact on geriatric IBD patient outcomes remains unexplored. Methods: Using 2016-2019 National Inpatient Sample data, we identified ≥65-year-old patients admitted for IBD (Crohn's, ulcerative colitis) management stratified by delirium presence as a secondary diagnosis. The study aimed to assess delirium's impact on geriatric IBD patient outcomes. Results: Among 67,534 elderly IBD admissions, 0.7% (470) developed delirium. The delirium group had a 4.8-fold increase in in-hospital mortality risk (odds ratio 4.80, P < 0.001, 95% confidence interval [CI] 1.94-11.8). IBD patients with delirium experienced prolonged length of stay (adjusted mean difference 5.15 days, 95% CI 3.24-7.06, P < 0.001) and increased care costs (adjusted mean difference $48,328, 95% CI $26,485-$70,171, P < 0.001) compared to those without delirium. Conclusion: Elderly IBD patients with delirium face higher mortality risk, prolonged hospitalization, and increased healthcare costs. Clinicians should recognize delirium's detrimental effects in this vulnerable group and adhere to preventive protocols for improved care.
RESUMO
INTRODUCTION: Esophageal Stents are used to maintain esophageal lumen patency in esophageal strictures caused by intrinsic and/or extrinsic malignancies and the occlusion of concomitant esophageal fistulas. While data on the efficacy and safety of esophageal stents exist, comprehensive evaluation of adverse events is limited. The aim of this study is to investigate the reported adverse events and device failures associated with esophageal self-expandable metal stents (SEMS) using the FDA's Manufacturer and User Facility Device Experience (MAUDE) database. METHODS: Post-marketing surveillance data for the esophageal SEMSs were analyzed using the FDA's MAUDE database from January 2014 to December 10, 2023. The outcomes of interest were patient-related adverse events and device failures. Statistical analysis was performed using Microsoft Excel 2010 and SPSS. Pooled numbers and percentages were calculated for each adverse event. Continuous variables underwent analysis using a two-tailed student t test, and significance was set to p ≤ 0.05. RESULTS: During the study period, 548 MAUDE reports revealed 873 device failures and 186 patient-related adverse events. The most common device issues were stent activation, positioning, or separation problems (4 n = 403; 46.2%), followed by device detachment or migration (n = 109, 12.5%), and material problems (n = 93, 10.7%). Patient complications included dysphagia/odynophagia (10%), perforation, pain, and bleeding (each 7.6%). The most common device failures in over-the-wire (OTW) stents and through-the-scope (TTS) stents were activation, positioning, or separation problems (TTS: n = 183, 52.6% vs OTW: n = 220, 41.9%). Compared to OTW stents, TTS stents had higher migration and breakage (13.5% vs. 11.8%, p = 0.24), and (9.2% vs. 6.7%, p = 0.08) respectively, while OTW stents had more challenges with stent advancement or removal (5.1% vs. 0.3%, p < 0.001 and 4.6% vs 3.4%, p = 0.19, respectively) and material problems (14.7% vs. 4.6%, p < 0.001). Activation, positioning, and separation problems were the most frequent device failures in fully covered (FC) and partially covered (PC) stents (FC: n = 62, 32.8%, PC: n = 168, 43.5%). FC stents had higher migration rates (20.6% vs 9.8%, p < 0.001), while PC stents exhibited more material problems (17.4% vs. 5.8%, p < 0.001) and difficulties with advancing the stents (6.7% vs. 0%, p < 0.001). CONCLUSION: Our examination showed a prevalence of reported device complications associated with stent activation, positioning, and separation problems. Dysphagia or odynophagia emerged as the most frequently reported patient complication. Furthermore, our analysis, provides insights into TTS vs. OTW and FC vs. PC esophageal SEMSs, enabling endoscopists and manufacturers to better understand adverse events and potentially optimize device design for future iterations.

RESUMO
CRC accounts for approximately a tenth of all cancer cases and deaths in the US. Due to large differences in demographics among the different states, we aim to determine trends in the CRC epidemiology and across different states, age groups, and genders. CRC rates, age-adjusted to the standard US population, were obtained from the GBD 2019 database. Time trends were estimated as annual percentage change (APC). A pairwise comparison was conducted between age- and gender-specific trends using the tests of parallelism and coincidence. Age-specific trends were also assessed in two age subgroups: younger adults aged 15-49 years and older adults aged 50-74 years. We also analyzed the prevalence, incidence, mortality, and DALYs in the US between 1990 and 2019. A total of 5.53 million patients were diagnosed with CRC in the US between 1990 and 2019. Overall, CRC incidence rates have significantly increased in younger adults (11.1 per 100,000 persons) and decreased in older adults (136.8 per 100,000 persons) (AAPC = 1.2 vs. -0.6; AAPC difference = 1.8, p < 0.001). Age-specific trends were neither identical (p < 0.001) nor parallel (p < 0.001), suggesting that CRC incidence rates are different and increasing at a greater rate in younger adults compared to older adults. However, for both men and women (49.4 and 35.2 per 100,000 persons), incidence rates have decreased over the past three decades at the same rate (AAPC = -0.5 vs. -0.5; AAPC difference = 0, p = 0.1). Geographically, the southern states had the highest mortality rates with Mississippi having the highest rate of 20.1 cases per 100,000 population in 2019. Massachusetts, New York, and the District of Colombia had the greatest decreases in mortality over the study period (-42.1%, -41.4%, and -40.9%). Decreased mortality was found in all states except Mississippi, where the mortality of CRC increased over the study period (+1.5%). This research provides crucial insights for policymakers to tailor resource allocation, emphasizing the dynamic nature of CRC burden across states and age groups, ultimately informing targeted strategies for prevention and intervention.
RESUMO
Various career paths exist for gastroenterology (GI) fellowship graduates across the country. These include further training, clinical or nonclinical job opportunities. Clinical career paths for those seeking jobs include academic positions or nonacademic positions (nonacademic hospital employed and private practice jobs). Data regarding career placement trends are limited. This study aims to explore temporal trends in career selection among new GI graduates. This is an observational cohort study. A list of GI fellowship programs was obtained from the FREIDA American Medical Association database. Programs with sufficient information on past graduate or alumni career placement after fellowship between 2017 and 2022 were included. Baseline characteristics and relevant information were collected. A Chi-square test was performed to assess the relationship between the categorical variables. A total of 203 GI fellowship programs were reviewed, among which only 21% (43/203) reported sufficient graduate career information. Across the 43 programs, 636 graduates were included. Thirty-three percent (210/636) of graduates were female. Forty-eight percent (308/636) of the graduates pursued nonacademic positions (nonacademic hospital employed and private practice jobs), 34% (216/636) into academic positions, and 17% (112/636) elected to do additional fellowship training. Both males and females were more likely to be employed in private practice (X2â =â 12.8, dfâ =â 2, Pâ =â .002). Navigating through the decision-making process of selecting the first job after fellowship can be challenging. Our study reveals higher preference for nonacademic roles among graduates, consistent over 5 years, suggesting need to explore obstacles for academic positions or further training.

OBJECTIVES: Colorectal canceris the third most common cancer worldwide, and kidney transplant patients have up to a 2.5-fold increased risk of colorectal cancer compared with the general population. Presently, colorectal cancer screening recommendations in kidney transplant candidates are the same as for the general population. We explored the literature on the prevalence of colonic polyps in patients with renal failure undergoing screening colonoscopy as part of kidney transplant evaluation. MATERIALS AND METHODS: We conducted a systematic review in PubMed, Embase, and Cochrane databases from inception through June 2023 to identify studies that explored the prevalence of colonic polyps in patients with chronic kidney disease undergoing a screening colonoscopy as part of their pretransplant evaluation. RESULTS: Of 937 patients, 371 had ≥1 polyp on their screening colonoscopy (39.6%; 95% CI, 29.3%-50.3%), 243 patients had ≥1 adenoma (25.9%; 95% CI, 14.3%- 39.6%), and 75 had ≥1 high-risk adenoma (8.7%; 95% CI, 6.9%-10.7%). Pooled analysis of the 2 studies comparing patients with end-stage renal disease versus matched control groups indicated higher pooled prevalence of adenomas in the end-stage renal disease group (33.4%) versus the control group (23.9%). CONCLUSIONS: Our results suggest an average or increased prevalence of polyps and adenomatous polyps in patients with chronic kidney disease undergoing colonoscopy during evaluation for kidney transplant. The pooled analysis of the studies comparing the end-stage renal disease population versus a matched control group indicates higher prevalence of adenomatous polyps in patients with end-stage renal disease. Multiple studies have shown that screening colonoscopy in this patient group is safe and does not delay kidney transplant evaluation or waitlistrates; hence, screening colonoscopy should be routinely considered.
