RESUMEN
Esophageal neuroendocrine carcinomas (NECs) are a rare type of esophageal neoplasm that can initially present with vague signs and symptoms. Gastrointestinal manifestations, such as dysphagia and abdominal discomfort, are the most common symptoms of neuroendocrine neoplasms. Although there is a potential for distant metastases because of esophageal NEC, few cases of brain metastasis have been reported. We report a rare case of an esophageal NEC metastasizing to the brain region.
RESUMEN
BACKGROUND: Post-esophagectomy anastomotic strictures are difficult to treat. The impact of adding local steroid injection to endoscopic dilation for the treatment of post-esophagectomy anastomotic strictures is unclear. We conducted a systematic review and meta-analysis to assess the efficacy of performing steroid injection in addition to dilation. METHODS: A search was conducted in MEDLINE, Cochrane Library, EMBASE, and Web of Science from inception to January 2019.âRandomized controlled trials (RCTs) comparing the efficacy of endoscopic dilation plus either local steroid injection (steroid group) or saline injection (placebo group) were included in the analysis. RESULTS: Three RCTs were eligible for the final analysis: 72 patients (mean age 61.3 years, 74â% male) in the steroid group and 72 patients (mean age 59.6 years, 71â% male) in the placebo group.âThe mean number of dilations required to resolve the stricture was significantly lower in the steroid group compared with the placebo group, with a mean weighted difference of -1.62 (95â% confidence interval [CI] -2.73 to -0.50; Pâ=â0.004). After 6 months of follow-up, there was a trend toward more patients in the steroid group remaining dysphagia free compared with the placebo group, with a pooled odds ratio of 2.36 (95â%CI 0.94 to 5.91; Pâ=â0.07, I2 â=â24â%). CONCLUSION: This meta-analysis showed that the addition of local steroid injection at the time of dilation for benign anastomotic strictures led to a significant decrease in the number of procedures required to resolve the stricture and may well reduce dysphagia symptoms during follow-up.

BACKGROUND & AIMS: The best method for endoscopic resection of sessile serrated polyps (SSP) 10 mm or larger is unclear; studies report variable outcomes in comparison to conventional adenomas. We performed a systematic review and meta-analysis to assess the efficacy and safety of resection of SSPs 10 mm or larger in size. METHODS: We searched the PubMed/MEDLINE, Google Scholar, Embase, and Cochrane databases for studies reporting data on endoscopic resection of SSPs 10 mm or larger, through May 31st, 2019. The primary outcome was rate of residual SSP, which was the rate of residual SSP found at the polypectomy site during the first follow-up colonoscopy. Secondary outcomes were: technical success (rate of complete macroscopic resection), R0 resection rate (complete histological resection with absence of any polyp tissue at the lateral and deep margins after en-bloc resection), and adverse events (immediate or delayed bleeding and perforation). We performed IQR,group analyses for outcomes based on polyp size and resection techniques. Pooled proportion rates (%) or odds ratio with 95% CIs with heterogeneity (I2) and P < .05. RESULTS: A total of 14 studies met the inclusion criteria: 911 patients (50.2% male; mean age, 62.8 ± 4.9 years) who underwent resection of 1137 SSPs (574 SSPs ≥ 20 mm) with a median polyp size of 19.4 mm (interquartile range, 15.9-29.6 mm). Follow-up information was available for 832 SSPs with a median follow-up duration of 12 months (interquartile range, 6-22.5 months). Piecemeal resection was performed in 58.5% SSPs. The pooled residual SSP rate was 4.3% (95% CI, 2%-6.5%). There was a higher residual SSP rate for polyps ≥ 20 mm compared to 10-19 mm (5.9% vs 1.2%; odds ratio, 3.02; 95% CI, 1-9.2; P = .049). Cold endoscopic mucosal resection (EMR) had significantly lower rates of delayed bleeding (0 vs 2.3%; P = .03) and residual polyp rate (0.9% vs 5%; P=.01) compared to hot EMR, based on univariate analysis. In multi-variate analysis there was no difference in residual polyp rate. There was no significant difference in other outcomes based on the size or method of resection. CONCLUSIONS: In a systematic review and meta-analysis, we found that SSPs ≥ 10 mm can be safely resected with low residual polyp rates. Polyp size ≥ 20 mm is a significant factor for residual polyp. Compared to hot EMR, cold EMR is associated with a lower rate of delayed bleeding. Randomized controlled trials comparing hot and cold resection are needed to standardize techniques and optimize outcomes.

BACKGROUND: The over-the-scope clip (OTSC) has been increasingly utilized for the management of gastrointestinal (GI) bleeding. Limited efficacy data are currently available from large-scale studies. METHODS: An electronic database search was conducted for eligible articles using OTSCs for hemostasis in GI bleeding. The primary outcome was the rate of definitive hemostasis after primary hemostasis and without rebleeding at follow-up.âSecondary outcomes were: primary technical success, primary clinical success, rebleeding, and failure rates. Pooled rates were expressed as proportions of patients with events over total patients, 95â% confidence limits (CI) with heterogeneity, and P values ofâ<â0.05 for significance. RESULTS: A total of 21 studies (nâ=â851) were analyzed (62.2â% males), with a median patient age of 69.7 years. The definitive hemostasis rate was 87.8â% (95â%CI 83.7â%â-â92â%) after a median follow-up of 56 days. The OTSC was successfully deployed in 97.8â% of patients (95â%CI 96.7â%â-â98.9â%) and the primary clinical success rate was 96.6â% (95â%CI 95.1â%â-â98.2â%). Rebleeding was seen in 10.3â% of patients (95â%CI 6.5â%â-â14.1â%). The failure rate of OTSCs was 9â% (95â%CI 5.2â%â-â12.8â%) when used as first-line treatment and 26â% (95â%CI 16.1â%â-â36.0â%) when used as second-line treatment. CONCLUSION: This systematic review showed high rates of definitive hemostasis, technical success, and clinical success, along with low rebleeding rates when OTSCs were used for the treatment of GI bleeding. The lack of randomized controlled trials of OTSC vs. other therapies makes comparison with conventional treatment difficult.

BACKGROUND AND AIMS: The evidence for modification of conventional colonoscopy using either "distal attachments" (DAs; endocap, endocuff, and endoring) or "electronic chromoendoscopy" (EC; narrow-band imaging [NBI], iScan, blue-light imaging, autofluorescence imaging, and linked-color imaging) to improve the detection of serrated adenomas during colonoscopy has shown conflicting results. METHODS: A comprehensive literature search was performed using Medline, Google Scholar, Embase, and Cochrane Library based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs) comparing any DA or EC with high-definition white-light colonoscopy for detection of serrated adenomas (sessile serrated adenoma/polyp and traditional serrated adenoma) were included. The primary outcome was serrated adenoma detection rate (SADR) defined as the number of patients with at least 1 serrated adenoma of total patients in that group. The secondary outcome was the number of serrated adenomas per subject. Pooled rates were reported using risk ratio (RR) with 95% confidence interval. RESULTS: Seventeen studies with 13,631 patients (56% men; age range, 50-66 years) met the inclusion criteria. The use of DAs (RR, 1.21; P = .45) and EC (RR, 1.29; P = .09) during colonoscopy did not show a significant improvement in SADR. The SADR using EC was 6.9% (4 studies) and that with NBI alone was 3.7% (3 studies). CONCLUSIONS: The results indicate that, except for NBI, the use of DAs or EC during colonoscopy does not improve detection of serrated adenomas in the colon. More RCTs evaluating NBI are needed to explore the effect.

Introduction In recent years, cold snare polypectomy (CSP) has increasingly been used over hot snare polypectomy (HSP) for the removal of colorectal polyps (4â-â10âmm in size). However, the optimal technique (CSP vs. HSP), in terms of complete polyp resection and complications, is uncertain. Our aim was to compare incomplete resection rate (IRR) of polyps and complications using CSP vs. HSP. Methods Randomized controlled studies (RCTs) comparing CSP and HSP for removal of 4â-â10âmm colorectal polyps were considered. Studies were included in the analysis if they obtained biopsy specimens from the resection margin to confirm the absence of residual tissue and reported complications. IRR and complication rate were the outcome measures. Pooled rates were reported as Odds Ratios (OR) or risk difference with 95â% Confidence Interval (CI). Results In total, three RCTs were included in the final analysis. A total of 1051 patients with 1485 polyps were randomized to either HSP group (nâ=â741 polyps) or CSP group (nâ=â744 polyps). The overall IRR did not differ between the two groups (HSP vs. CSP: 2.4â% vs. 4.7â%; OR 0.51, 95â%CI 0.13â-â1.99, P â=â0.33, I 2 â=â73â%). The HSP group had a lower rate of overall complications compared to the CSP group (3.7â% vs. 6.6â%; OR 0.53, 95â% CI 0.3â-â0.94, P â=â0.03, I 2 â=â0 %). Polyp retrieval rates were not different between the two groups (99â% vs. 98.1â%). Conclusion Our results suggest that HSP and CSP techniques can be effectively used for the complete removal of 4â-â10âmm colorectal polyps; however, HSP has a lower incidence of overall complications.
RESUMEN
BACKGROUND: Although shorter lengths of Barrett's esophagus (BE) have been associated with a lower risk of neoplastic progression, precise estimates have varied, especially for non-dysplastic BE (NDBE) only. Therefore, current US guidelines do not provide specific recommendations on surveillance intervals based on BE length. We performed a systematic review and meta-analysis of the published literature to examine neoplastic progression rates of NDBE based on BE length. METHODS: PubMed, Cochrane, Google Scholar, and Embase were comprehensively searched. Studies reporting progression rates in patients with NDBE and >â1 year of follow-up were included. The number of patients progressing to esophageal adenocarcinoma (EAC) and high grade dysplasia (HGD)/EAC in individual studies and the mean follow-up were recorded to derive person-years of follow-up.âPooled rates of progression to EAC and HGD/EAC based on BE length (<â3âcm vs. ≥â3âcm) were calculated. RESULTS: Of the 486 initial studies identified, 10 met the inclusion/exclusion criteria. These included a total of 4097 NDBE patients; 1979 with short-segment BE (SSBE; 10â773 person-years of follow-up) and 2118 with long-segment BE (LSBE; 12â868 person-years). The annual rates of progression to EAC were significantly lower for SSBE compared with LSBE: 0.06â% (95â% confidence interval 0.01â%â-â0.10â%) vs. 0.31â% (0.21â%â-â0.40â%), respectively; odds ratio (OR) 0.25 (0.11â-â0.56); Pâ<â0.001, as were the rates for the combined endpoint (HGD/EAC): 0.24â% (0.09â%â-â0.32â%) vs. 0.76â% (0.43â%â-â0.89â%), respectively; OR 0.35 (0.21â-â0.58); Pâ<â0.001. There was no significant heterogeneity among studies. CONCLUSION: The results demonstrate significantly lower rates of neoplastic progression in NDBE patients with SSBE compared with LSBE. BE length can easily be used for risk stratification purposes for NDBE patients undergoing surveillance endoscopy and consideration should be given to tailoring surveillance intervals based on BE length in future US guidelines.

BACKGROUND AND AIMS: Hot snare polypectomy and EMR are the standard of care in resecting colorectal polyps ≥10 mm. To avoid the risk of electrocautery-induced damage, there is recent evidence about using cold snare polypectomy and cold EMR for such lesions. The aim of this pooled analysis is to report outcomes of cold snare resection for polyps ≥10 mm. METHODS: PubMed/Medline, Embase, Google Scholar, and Cochrane databases were searched up to July 2018 to identify studies that performed cold snare resection for colorectal polyps ≥10 mm. Primary outcomes were adverse events (bleeding, perforation, and postpolypectomy abdominal pain), and secondary outcomes were the rates of complete resection, overall residual polyp rates, and rates for adenomas versus sessile serrated polyps (SSPs). Subgroup analysis was performed focusing on lesion size, location, and resection technique. RESULTS: Eight studies were included in the final analysis that included 522 colorectal polyps with a mean polyp size of 17.5 mm (range, 10-60). The overall adverse event rate was 1.1% (95% confidence interval, CI, 0.2%-2.0%; I2 = 0%). Intra- and postprocedural bleeding rates were .7% (95% CI, 0%-1.4%) and .5% (95% CI, .1%-1.2%), respectively, with abdominal pain rate being .6% (95% CI, .1%-1.3%). Polyps ≥20 mm had a higher intraprocedural bleeding rate of 1.3% (95% CI, .7%-3.3%) and abdominal pain rate of 1.2% (95% CI, .7%-3.0%) but no delayed bleedings. No perforations were reported. The complete resection rate was 99.3% (95% CI, 98.6%-100%). Overall pooled residual rates of polyps of any histology, adenomas, and SSPs were 4.1% (95% CI, .2%-8.4%), 11.1% (95% CI, 4.1%-18.1%), and 1.0% (95% CI, .4%-2.4%), respectively, during a follow-up period ranging from 154 to 258 days. CONCLUSIONS: The results of this systematic review and pooled analysis were excellent with cold snare resection of colorectal polyps >10 mm in terms of postpolypectomy bleeding, complete resection, and residual polyp rates. Randomized controlled trials comparing cold snare resection with hot snare resections of polyps ≥10 mm are required for further investigation.

BACKGROUND AND AIMS: Right-sided lesions are often missed during standard colonoscopy (SC). A second forward-view examination or retroflexion in the right side of the colon have both been proposed as techniques to improve adenoma detection rate (ADR) in the right side of the colon. Comparative data on examining the right side of the colon with a second forward view or retroflexion is not known in a pooled analysis. We performed a systematic review of the literature to assess the yield of a second forward view compared with retroflexion examination for the detection of right-sided adenomas. METHODS: A systematic literature search was performed using the following databases: PubMed, Embase, Web of Science, and Cochrane. Only full-length published articles that provided information on adenoma detection and miss rates during either a second forward view or retroflexed view of the right side of the colon after the initial standard forward withdrawal (SC) were included. The following outcomes were assessed: comparison of adenoma miss rate (AMR) for second forward view versus retroflexion after SC, AMR of SC compared with second forward view, AMR of SC compared with retroflexion, and right-sided adenoma detection with second forward view and retroflexion. Pooled rates were reported as risk difference or odds ratios (OR) with 95% confidence intervals (CI) with a P value <.05 indicating statistical significance. Statistical analysis was performed with Review Manager v5.3. RESULTS: We identified 4 studies with 1882 patients who underwent a second forward view of the right side of the colon after an initial SC. The average age of the patients was 58.3 years. Data on right-sided ADR were available from all 4 studies for the second forward view; however, only 2 of the studies provided information on right-sided ADR with retroflexion. The pooled estimate of AMR of a single SC was 13.3% (95% CI, 6.6%-20%) compared with a second forward-view examination (n = 4), whereas it was 8.1% (3.7%-12.5%) compared with a retroflexion examination (n = 3). However, when the second forward view was compared with retroflexion in terms of AMR from an analysis of 3 eligible studies, there was no statistically significant difference (7.3% vs 6.3%; pooled OR, 1.2; 95% CI, 0.9-1.61; P = .21). Second forward view of the right side of the colon increased the right-sided ADR by 10% (n = 4; second forward view vs SC, 33.6% vs 26.7%) with a pooled risk difference of 0.09 (95% CI, 0.03-0.15; P < .01). Retroflexion increased the right-sided ADR by 6% (n = 3; retroflexion vs SC, 28.4% vs 22.7%) with a pooled risk difference of 0.06 (95% CI, 0.03-0.09; P < 01). CONCLUSION: After SC withdrawal, a second forward view and retroflexed view of the right side of the colon are both associated with improvement in ADR. One of these techniques should be considered during SC to increase ADR and to improve the quality of colonoscopy.

Background and Aims. We initiated peroral endoscopic myotomy (POEM) utilizing a two-person technique with combination of an advanced endoscopist and a thoracic surgeon with complementary skills. Our aim was to determine the feasibility and outcomes in initial 20 patients. Methods. In this observational study, main outcomes measured were therapeutic success in relieving symptoms (Eckardt score < 3), decrease in lower esophageal sphincter (LES) pressures, improvement in emptying on timed barium esophagogram (TBE), and complications. Results. POEM was successful in all 20 patients with a mean operative time of 140.1 + 32.9 minutes. Eckardt symptom scores decreased significantly at two-month follow-up (6.4 + 2.9 versus 0.25 + 0.45, p < 0.001). Both basal and residual LES pressures decreased significantly (28.2 + 14.1 mmHg versus 12.8 + 6.3 and 22.4 + 11.3 versus 6.3 + 3.4 mmHg, p = 0.025 and <0.001, resp.). Barium column height at 5 minutes on TBE reduced from 6.8 + 4.9 cm to 2.3 + 2.9 cm (p = 0.05). Two patients (10%) had mucosal perforations and one had delayed bleeding (5%). Conclusions. Two-person technique of POEM with combination of an advanced endoscopist and a thoracic surgeon is highly successful with low risk of complications.

BACKGROUND: Identification of colonoscopic features which increase colitis-associated neoplasia risk in patients with ulcerative colitis (UC) may allow patient risk stratification. Our objective was to investigate whether colonoscopic features correlate with the risk of developing colitis-associated neoplasia in patients with UC on surveillance. METHODS: In this retrospective case-control study, patients with UC who underwent surveillance colonoscopies from 1998 to 2011 were included. Patients with UC with neoplasia were compared with a matched control group of patients with UC without neoplasia in a 1:3 ratio. RESULTS: A total of 111 eligible patients with UC with colon neoplasia were compared with 356 patients with UC without colon neoplasia. On univariate analysis, colitis-associated neoplasia was associated with male gender (odds ratio [OR] = 2.58, 95% confidence interval [CI]: 1.71-3.89, P ≤ 0.001) and smoking history (OR = 1.62, 95% CI: 1.1-2.39, P = 0.045) but not with colonoscopic features, including tubular colon/shortened colon, scarring, segment of severe inflammation, inflammatory polyps, colonic stricture, or macroscopically normal appearance colonoscopy. In multivariate analysis, only male gender (OR = 2.68, 95% CI: 1.77-4.08, P ≤ 0.001) was found to be associated with an increased risk, whereas the use of 5-aminosalicylates was associated with a decreased risk for colitis-associated neoplasia (OR = 0.51, 95% CI: 0.31-0.84, P = 0.009). CONCLUSIONS: In patients with UC, colonoscopic features especially on standard-definition white-light colonoscopy did not appear to reliably predict the development of colitis-associated neoplasia. This will leave room for image-enhanced endoscopy technology and molecular markers for the early and accurate detection of colitis-associated neoplasia.

AIM: To assess and compare the esophageal function after peroral endoscopic myotomy (POEM) vs other conventional treatments in achalasia. METHODS: Chart review of all achalasia patients who underwent POEM, laparoscopic Heller myotomy (LHM) or pneumatic dilation (PD) at our institution between January 2012 and March 2015 was performed. Patient demographics, type of achalasia, prior treatments, pre- and post-treatment timed barium swallow (TBE) and high-resolution esophageal manometry (HREM) findings were compared between the three treatment groups. Patients who had both pre- and 2 mo post-treatment TBE or HREM were included in the final analysis. TBE parameters compared were barium column height, width and volume of barium remaining at 1 and 5 min. HREM parameters compared were basal lower esophageal sphincter (LES) pressures and LES-integrated relaxation pressures (IRP). Data are presented as mean ± SD, median [25(th), 75(th) percentiles] or frequency (percent). Analysis of variance, Kruskal-Wallis test, Pearsons χ(2) test and Fishers Exact tests were used for analysis. RESULTS: A total of 200 achalasia patients were included of which 36 underwent POEM, 22 underwent PD and 142 underwent LHM. POEM patients were older (55.4 ± 16.8 years vs 46.5 ± 15.7 years, P = 0.013) and had higher BMI than LHM (29.1 ± 5.9 kg/m(2) vs 26 ± 5.1 kg/m(2), P = 0.012). More number of patients in POEM and PD groups had undergone prior treatments compared to LHM group (72.2% vs 68.2% vs 44.3% respectively, P = 0.003). At 2 mo post-treatment, all TBE parameters including barium column height, width and volume remaining at 1 and 5 min improved significantly in all three treatment groups (P = 0.01 to P < 0.001) except the column height at 1 min in PD group (P = 0.11) . At 2 mo post-treatment, there was significant improvement in basal LES pressure and LES-IRP in both LHM (40.5 mmHg vs 14.5 mmHg and 24 mmHg vs 7.1 mmHg respectively, P < 0.001) and POEM groups (38.7 mmHg vs 11.4 mmHg and 23.6 mmHg vs 6.6 mmHg respectively, P < 0.001). However, when the efficacy of three treatments were compared to each other in terms of improvement in TBE or HREM parameters at 2 mo, there was no significant difference (P > 0.05). CONCLUSION: POEM, PD and LHM were all effective in improving esophageal function in achalasia at short-term. There was no difference in efficacy between the three treatments.

BACKGROUND: The association between primary sclerosing cholangitis (PSC) and underlying inflammatory bowel disease (IBD) is well established. There are scant data on the association between non-IBD immunological diseases (NID) and PSC outcomes. Our objective was to investigate the impact of NID on the clinical outcomes in patients with PSC. METHODS: We included 287 patients with PSC from 1985 to 2013 from our tertiary care data registry. Univariate and multivariate analyses were performed to assess the risk factors for liver transplantation. RESULTS: Of the 287 patients with PSC, 38 (13.2%) patients had at least 1 concomitant immunological disease other than IBD; 241 patients (84.0%) had concurrent IBD. The most frequent NIDs were autoimmune thyroiditis, autoimmune hepatitis, and rheumatoid arthritis. The median follow-up time did not differ significantly between PSC patients with and without NID (10.5 years versus 7.0 years, P = 0.04). We did not find significant difference in the median time from PSC diagnosis to liver transplantation between PSC patients with and without NID (5.2 versus 6.3 years, P = 0.74). In the subgroup analysis, there was no significant difference in the median time from PSC diagnosis to liver transplantation between the PSC-only group, PSC with IBD group, and PSC with NID group (5.4 versus 6.4 versus 5.2 years, P = 0.22). CONCLUSIONS: The association of NID in patients with PSC did not seem to affect the need for liver transplantation or transplantation-free survival. The findings suggest that the increased load of autoimmunity, including the presence of IBD or NID, has a minimum impact on the disease outcome of PSC.

BACKGROUND: The comparative outcomes of ulcerative colitis (UC) and Crohn's disease (CD) in patients with primary sclerosing cholangitis (PSC) are unclear; the aim of our study was to make an objective comparison. METHODS: A total of 273 patients with PSC and inflammatory bowel disease (223 with UC and 50 with CD) were included. Clinical and demographic variables were obtained. RESULTS: The PSC risk score was similar for both groups. The median follow-up period in patients with PSC-UC was 12 years (range 0-38) and that for PSC-CD was 14 years (range 1-36). The median number of disease flares per year was higher in PSC-UC patients than in the PSC-CD group [1vs.0 (ranges 0-20 and 0-9, respectively); P < 0.001]. More patients with UC developed colon neoplasia than CD (35.9% vs.18%; P = 0.009). On proportional hazards analysis for the risk of colectomy, UC patients had a 12% higher risk for colectomy [hazard ratio (HR) = 0.88; 95% confidence interval (CI) 0.51-1.51; P = 0.64]. Liver transplantation for PSC was associated with decreased risk (HR = 0.57; 95% CI 0.37-0.89; P = 0.013), while colon neoplasia increased the risk (HR = 3.83; 95% CI 2.63-5.58; P < 0.001) for colectomy. On proportional hazards analysis for the risk of colon neoplasia, UC patients had 56% higher risk of developing colon neoplasia than CD (HR = 0.44; 95% CI 0.16-1.25; P = 0.12). CONCLUSIONS: PSC patients with CD appear to be associated with a lower risk of colon neoplasia and colectomy than PSC patients with UC.
RESUMEN
BACKGROUND: ERCP is frequently used in patients with primary sclerosing cholangitis (PSC) for cancer surveillance and treatment of dominant strictures. OBJECTIVE: To evaluate the prevalence and risk factors for ERCP-related adverse events in patients with PSC. DESIGN: Retrospective analysis of ERCPs performed from 1998 to 2012. SETTING: Referral center. PATIENTS: A total of 294 consecutive patients with PSC who underwent a total of 657 ERCPs. INTERVENTIONS: ERCP. MAIN OUTCOME MEASUREMENTS: ERCP-related adverse events and predictive factors were determined by univariate and multivariate analyses. RESULTS: ERCP use in patients with PSC showed a significant increase during the second half of the study period (2006-2012) compared with the first half (1998-2005) (437 vs 220 procedures; P = .04). Primary cannulation was successful in 634 procedures (96.6%) or in 271 of 294 patients (92.2%). Access to the bile duct was achieved with a needle-knife in 19 procedures (2.9%), whereas ERCP was unsuccessful in 4 of 657 procedures (0.6%), and successful percutaneous drainage was performed. Post-ERCP pancreatitis (PEP) was diagnosed in 8 (1.2%), cholangitis in 16 (2.4%), and bleeding in 4 (0.7%) procedures. Overall, risk of any adverse event was 28 of 657 (4.3%) procedures. On multivariate analysis, performing biliary sphincterotomy (odds ratio [OR] 5.04; 95% confidence interval [CI], 2.01-12.60; P = .001) and passage of a guidewire into the pancreatic duct (OR 4.54; 95% CI, 1.44-14.30; P = .010) were independently associated with an increased risk of any adverse event. LIMITATIONS: Retrospective study. CONCLUSION: Cholangitis appears to be the most common adverse event despite intraprocedural antibiotic use. There was a low risk of adverse events in patients with PSC undergoing ERCP.
