RESUMO
DESCRIPTION: The purpose of this American Gastroenterological Association (AGA) Institute Clinical Practice Update is to review the available published evidence and expert advice regarding the clinical management of patients with pregnancy-related gastrointestinal and liver disease. METHODS: This expert review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership and underwent internal peer review by the Clinical Practice Updates Committee and external peer review through the standard procedures of Gastroenterology. This article provides practical advice for the management of pregnant patients with gastrointestinal and liver disease based on the best available published evidence. The Best Practice Advice statements were drawn from a review of the published literature and from expert opinion. Because formal systematic reviews were not performed, these Best Practice Advice statements do not carry formal ratings regarding the quality of evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: To optimize gastrointestinal and liver disease before pregnancy, preconception and contraceptive care counseling by a multidisciplinary team should be encouraged for reproductive-aged persons who desire to become pregnant. BEST PRACTICE ADVICE 2: Procedures, medications, and other interventions to optimize maternal health should not be withheld solely because a patient is pregnant and should be individualized after an assessment of the risks and benefits. BEST PRACTICE ADVICE 3: Coordination of birth for a pregnant patient with complex inflammatory bowel disease, advanced cirrhosis, or a liver transplant should be managed by a multidisciplinary team, preferably in a tertiary care center. BEST PRACTICE ADVICE 4: Early treatment of nausea and vomiting of pregnancy may reduce progression to hyperemesis gravidarum. In addition to standard diet and lifestyle measures, stepwise treatment consists of symptom control with vitamin B6 and doxylamine, hydration, and adequate nutrition; ondansetron, metoclopramide, promethazine, and intravenous glucocorticoids may be required in moderate to severe cases. BEST PRACTICE ADVICE 5: Constipation in pregnant persons may result from hormonal, medication-related, and physiological changes. Treatment options include dietary fiber, lactulose, and polyethylene glycol-based laxatives. BEST PRACTICE ADVICE 6: Elective endoscopic procedures should be deferred until the postpartum period, whereas nonemergent but necessary procedures should ideally be performed in the second trimester. Pregnant patients with cirrhosis should undergo evaluation for, and treatment of, esophageal varices; upper endoscopy is suggested in the second trimester (if not performed within 1 year before conception) to guide consideration of nonselective ß-blocker therapy or endoscopic variceal ligation. BEST PRACTICE ADVICE 7: In patients with inflammatory bowel disease, clinical remission before conception, during pregnancy, and in the postpartum period is essential for improving outcomes of pregnancy. Biologic agents should be continued throughout pregnancy and the postpartum period; use of methotrexate, thalidomide, and ozanimod must be stopped at least 6 months before conception. BEST PRACTICE ADVICE 8: Endoscopic retrograde cholangiopancreatography during pregnancy may be performed for urgent indications, such as choledocholithiasis, cholangitis, and some cases of gallstone pancreatitis. Ideally, endoscopic retrograde cholangiopancreatography should be performed during the second trimester, but if deferring the procedure may be detrimental to the health of the patient and fetus, a multidisciplinary team should be convened to decide on the advisability of endoscopic retrograde cholangiopancreatography. BEST PRACTICE ADVICE 9: Cholecystectomy is safe during pregnancy; a laparoscopic approach is the standard of care regardless of trimester, but ideally in the second trimester. BEST PRACTICE ADVICE 10: The diagnosis of intrahepatic cholestasis of pregnancy is based on a serum bile acid level >10 µmol/L in the setting of pruritus, typically during the second or third trimester. Treatment should be offered with oral ursodeoxycholic acid in a total daily dose of 10-15 mg/kg. BEST PRACTICE ADVICE 11: Management of liver diseases unique to pregnancy, such as pre-eclampsia; hemolysis, elevated liver enzymes, and low platelets syndrome; and acute fatty liver of pregnancy requires planning for delivery and timely evaluation for possible liver transplantation. Daily aspirin prophylaxis for patients at risk for pre-eclampsia or hemolysis, elevated liver enzymes, and low platelets syndrome is advised beginning at week 12 of gestation. BEST PRACTICE ADVICE 12: In patients with chronic hepatitis B virus infection, serum hepatitis B virus DNA and liver biochemical test levels should be ordered. Patients not on treatment but with a serum hepatitis B virus DNA level >200,000 IU/mL during the third trimester of pregnancy should be considered for treatment with tenofovir disoproxil fumarate. BEST PRACTICE ADVICE 13: In patients on immunosuppressive therapy for chronic liver diseases or after liver transplantation, therapy should be continued at the lowest effective dose during pregnancy. Mycophenolate mofetil should not be administered during pregnancy.
RESUMO
BACKGROUND AND AIMS: Liquid nitrogen spray cryotherapy (SCT) is an alternative to radiofrequency ablation (RFA) for eradication of dysplastic Barrett's esophagus (BE). We aimed to assess the safety, efficacy, and durability of SCT in a multicenter U.S. registry. METHODS: This is a multicenter prospective registry of adults with BE treated with truFreeze Spray Cryotherapy (Steris, Mentor, Ohio, USA) (4 community and 11 academic sites, 2013-2022). Complete eradication of intestinal metaplasia (CEIM) and dysplasia (CED) were assessed in BE with dysplasia or intramucosal adenocarcinoma. Kaplan-Meier analysis of CEIM and CED was performed. Hazard ratios for CEIM stratified by baseline risk factors were calculated. RESULTS: Among 138 subjects with low-grade dysplasia (24%), high-grade dysplasia (49%), and intramucosal adenocarcinoma (27%), 34% received prior RFA therapy. Subjects received a median of 2 SCT sessions. Adverse events were uncommon, with 5.5% reporting strictures and 0.7% a perforation. Rates of CEIM and CED, respectively, were 66% and 84% after 2 years and 67% and 92% after 3 years. In RFA-naïve patients, CEIM was 77% and CED was 96% at 3 years. Increasing BE length (per centimeter: adjusted hazard ratio, 0.90; 95% confidence interval, 0.83-0.96) and prior treatment with RFA (adjusted hazard ratio, 0.39; 95% confidence interval, 0.22-0.69) were associated with a lower rate of CEIM. Recurrence occurred in 8.8% (n = 6) at a mean follow-up of 2.5 years after CEIM. CONCLUSION: In this largest reported prospective cohort, liquid nitrogen SCT was safe and effective for the treatment of dysplastic and neoplastic BE. Response was lower in those with prior failed RFA; in that cohort, approximately 50% attained CEIM at 3 years.

BACKGROUND & AIMS: Despite the significant advances made in the diagnosis and treatment of Barrett's esophagus (BE), there is still a need for standardized definitions, appropriate recognition of endoscopic landmarks, and consistent use of classification systems. Current controversies in basic definitions of BE and the relative lack of anatomic knowledge are significant barriers to uniform documentation. We aimed to provide consensus-driven recommendations for uniform reporting and global application. METHODS: The World Endoscopy Organization Barrett's Esophagus Committee appointed leaders to develop an evidence-based Delphi study. A working group of 6 members identified and formulated 23 statements, and 30 internationally recognized experts from 18 countries participated in 3 rounds of voting. We defined consensus as agreement by ≥80% of experts for each statement and used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tool to assess the quality of evidence and the strength of recommendations. RESULTS: After 3 rounds of voting, experts achieved consensus on 6 endoscopic landmarks (palisade vessels, gastroesophageal junction, squamocolumnar junction, lesion location, extraluminal compressions, and quadrant orientation), 13 definitions (BE, hiatus hernia, squamous islands, columnar islands, Barrett's endoscopic therapy, endoscopic resection, endoscopic ablation, systematic inspection, complete eradication of intestinal metaplasia, complete eradication of dysplasia, residual disease, recurrent disease, and failure of endoscopic therapy), and 4 classification systems (Prague, Los Angeles, Paris, and Barrett's International NBI Group). In round 1, 18 statements (78%) reached consensus, with 12 (67%) receiving strong agreement from more than half of the experts. In round 2, 4 of the remaining statements (80%) reached consensus, with 1 statement receiving strong agreement from 50% of the experts. In the third round, a consensus was reached on the remaining statement. CONCLUSIONS: We developed evidence-based, consensus-driven statements on endoscopic landmarks, definitions, and classifications of BE. These recommendations may facilitate global uniform reporting in BE.

INTRODUCTION: Given variability in parental leave policies in gastroenterology (GI) with little data on outcomes, the American College of Gastroenterology conducted a survey to assess policies and outcomes. METHODS: A survey was distributed to American College of Gastroenterology members with questions on demographics, fertility, pregnancy outcomes, and parental leave policies. RESULTS: There were 796 responses, with 52.5% female individuals. Many (57%) delayed parenting. High rates of infertility (21%) and pregnancy complications (68%) were observed. Satisfaction with parental leave policies in GI was low (35%). DISCUSSION: Our survey highlights the need for policies that support the well-being of our GI colleagues and families.

BACKGROUND AND AIMS: Endoscopic mucosal resection (EMR) with use of electrocautery (conventional EMR) has historically been used to remove large duodenal adenomas, however, use of electrocautery can predispose to adverse events including delayed bleeding and perforation. Cold snare EMR (cs-EMR) has been shown to be safe and effective for removal of colon polyps, but data regarding its use in the duodenum is limited. The aim of this study is to evaluate the efficacy and safety of cs-EMR for nonampullary duodenal adenomas ≥1 cm. METHODS: This was a multicenter retrospective study of patients with nonampullary duodenal adenomas ≥1 cm who underwent cs-EMR between October 2014 and May 2023. Patients who received any form of thermal therapy were excluded. Primary outcomes were technical success and rate of recurrent adenoma. Secondary outcomes were adverse events and predictors of recurrence. RESULTS: A total of 125 patients underwent resection of 127 nonampullary duodenal adenomas with cs-EMR. Follow up data was available in 89 cases (70.1%). The recurrent adenoma rate was 31.5% (n=28). Adverse events occurred in 3.9% (n=5) with four cases of immediate bleeding (3.1%) and one case of delayed bleeding (0.8%). There were no cases of perforation. The presence of high-grade dysplasia was found to be an independent predictor of recurrence (OR: 10.9 [95% CI: 1.1-102.1], p=0.036). CONCLUSION: This retrospective multicenter study demonstrates that cs-EMR for nonampullary duodenal adenomas is safe and technically feasible with an acceptable recurrence rate. Future prospective studies are needed to directly compare outcomes of cs-EMR with conventional and underwater EMR.
RESUMO
BACKGROUND AND AIMS: Endoscopy-related musculoskeletal injuries (ERI) are increasingly prevalent in adult endoscopists; however, there are no studies that have evaluated ERI and ergonomic practices among pediatric gastroenterologists and trainees. We aimed to examine the prevalence, nature, and impact of musculoskeletal injuries in pediatric endoscopic practice and assess attitudes towards ergonomic training needs. METHODS: Pediatric gastroenterologists and trainees were surveyed to collect information on endoscopist and practice characteristics, the prevalence, nature, and impacts of ERI, ergonomics strategies employed in practice, previous ergonomics training, and perceptions of ergonomics training (elicited using a 1 (strongly disagree) to 5 (strongly agree) Likert scale). Responses were analyzed using descriptive statistics, and bivariate analyses were conducted to explore correlates of ERI. RESULTS: Among 146 survey respondents, 50 (34.2%) were trainees and 96 (65.8%) were practicing endoscopists with a mean duration of endoscopic practice of 9.7 ± 9.4 years. Overall, 55.6% (n = 80/144) reported experiencing a musculoskeletal injury, with 34.7% (n = 50/144) reporting an injury attributable to endoscopy. Among those with ERI, the most common sites were the neck/upper back (44.0%), thumb (42.0%), hand/finger (38.0%), and lower back (36.0%). Women were more likely to experience ERI compared to men (43.4% vs. 23.4%; p = 0.013). Only 20.9% of participants had formal training in ergonomics. Respondents reported being motivated to implement practice changes to prevent ERI (4.41 ± 0.95) and perceived ergonomics training as important (4.37 ± 0.96). CONCLUSIONS: Pediatric endoscopists, and particularly women, experience significant ERI; however, formal endoscopy ergonomics training is rare. Improved ergonomics training is needed for both practicing pediatric gastroenterologists and trainees.

BACKGROUND: Recent advances in modern medicine have translated into increase in life expectancy in the USA and with that, a rise in the demand for invasive procedures in elderly patients. Endoscopic retrograde cholangiopancreatography (ERCP) is the procedure of choice for managing various benign and malignant pancreatobiliary conditions and can be associated with various adverse events. AIM: We performed a systematic review and meta-analysis to evaluate outcomes of ERCP in nonagenarians. METHODS: A comprehensive literature search was performed in Embase, MEDLINE, Web of Science, and Cochrane Review library until July 2020. Our primary outcomes were the rate of technical success and adverse events in nonagenarians. Secondary outcomes were comparison of technical success and adverse events compared with younger patients. RESULTS: The initial search revealed 4933 studies, of which 24 studies with 5521 patients met our inclusion criteria. Pooled technical success rate of ERCP in nonagenarians was 92%, and pooled adverse event rate was 7.8%. There was no significant difference in technical success rate and overall rate of adverse events comparing ERCP outcomes in nonagenarians with a relatively younger population. The risk of post-ERCP bleeding was significantly higher in nonagenarians compared to younger patients with OR = 1.986 [1.113-3.544], I2 = 0. ERCP-related mortality was also significantly higher in nonagenarians compared to younger patients with OR = 4.720 [1.368-16.289], I2 = 0. CONCLUSION: There was no significant difference in technical success rate and risk of adverse events related to ERCP in nonagenarians compared to younger patients. However, the risk of bleeding and procedure-related mortality was significantly higher.

INTRODUCTION: Endoscopy-related injury (ERI) is common in gastroenterologists (GI). The study aim was to assess the prevalence of self-reported ERI, patterns of injury, and endoscopist knowledge of preventative strategies in a nationally representative sample. METHODS: A 38-item electronic survey was sent to 15,868 American College of Gastroenterology physician members. The survey was completed by 1,698 members and was included in analyses. Descriptive, univariate, and multivariate analyses were conducted to evaluate the likelihood of ERI based on workload parameters and gender. RESULTS: ERI was reported by 75% of respondents. ERI was most common in the thumb (63.3%), neck (59%), hand/finger (56.5%), lower back (52.6%), shoulder (47%), and wrist (45%). There was no significant difference in the prevalence of ERI between men and women GI. However, women GI were significantly more likely to report upper extremity ERI while men were more likely to report lower-back pain-related ERI. Significant gender differences were noted in the reported mechanisms attributed to ERI. Most respondents did not discuss ergonomic strategies in their current practice (63%). ERI was less likely to be reported in GI who took breaks during endoscopy (P = 0.002). DISCUSSION: ERI is highly prevalent in GI physicians. Significant gender differences regarding specific sites affected by ERI and the contributing mechanisms were observed. Results strongly support institution of training in ergonomics for all GI as a strategy to prevent its impact on providers of endoscopy.

PURPOSE OF REVIEW: Hepatobiliary complications are common in Roux-en-Y gastric bypass (RYGB) patients. Despite development of multiple surgical and endoscopic access techniques over the years, ERCP using standard duodenoscope remains challenging in these patients due to the altered anatomy. RECENT FINDINGS: Limited success with enteroscope-assisted and laparoscope-assisted ERCP led to the evolution of the novel EUS-directed transgastric ERCP (EDGE) procedure, with variations of this technique termed as Gastric Access Temporary for Endoscopy (GATE), EUS-guided TransGastric ERCP (EUS-TG-ERCP), EUS-guided GastroGastrostomy-assisted ERCP (EUS-GG-ERCP), and EUS-directed transgastric intervention (EDGI). EDGE has high technical (100%) and clinical success rates (60-100%), lower adverse event rate (1.5-7.6%), and up to 20% access stent migration rate; without any significant weight changes. EDGE has significantly shorter procedure time (73vs184min), post-procedural hospital stays (0.8vs2.65 days) and is more cost effective compared to other modalities. EDGE technique addresses the challenges of RYGB anatomy as a minimally invasive, clinically successful, fully endoscopic, and cost-effective option. We present a literature review of the EDGE technique from its inception to current, in addition to reviewing other access techniques, their advantages, disadvantages and outcomes.

BACKGROUND: Biliary cannulation is readily achieved in > 85% of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). When standard cannulation techniques fail, salvage techniques utilized include the needle knife precut, double wire technique, and Goff septotomy. METHODS: Records of patients undergoing ERCP from 2005 to 2016 were retrospectively examined using a prospectively maintained endoscopy database. Patients requiring salvage techniques for biliary access were analyzed together with a control sample of 20 randomly selected index ERCPs per study year. Demographic and clinical variables including indications for ERCP, cannulation rates, and adverse events were collected. RESULTS: A total of 7984 patients underwent ERCP from 2005 to 2016. Biliary cannulation was successful in 94.9% of control index ERCPs, 87.2% of patients who underwent Goff septotomy (significantly higher than for all other salvage techniques, p ≤ 0.001), 74.5% of patients in the double wire group and 69.6% of patients in the needle knife precut group. Adverse event rates were similar in the Goff septotomy (4.1%) and index ERCP control sample (2.7%) groups. Adverse events were significantly higher in the needle knife group (27.2%) compared with all other groups. CONCLUSIONS: This study represents the largest study to date of Goff septotomy as a salvage biliary access technique. It confirms the efficacy of Goff septotomy and indicates a safety profile similar to standard cannulation techniques and superior to the widely employed needle knife precut sphincterotomy. Our safety and efficacy data suggest that Goff septotomy should be considered as the primary salvage approach for failed cannulation, with needle knife sphincterotomy restricted to Goff septotomy failures.

BACKGROUND: Endoscopic eradication therapy of dysplastic Barrett's esophagus (BE) and early esophageal neoplasia has emerged as an effective treatment option. Data for the role of spray cryotherapy (SCT) in this setting is relatively limited. OBJECTIVE: To evaluate the safety and long-term outcomes of SCT-based multimodal therapy in the management of dysplastic BE and early esophageal neoplasia. DESIGN: Single-center, retrospective, cohort study. SETTING: Academic, tertiary care center between August 2008 and February 2019. METHODS: A retrospective chart review was conducted of the prospectively maintained endoscopic cryotherapy database at our center. Fifty-seven patients were identified who underwent SCT treatment for dysplastic BE and esophageal or Gastro-esophageal (GE) junction adenocarcinoma during the study period. Primary outcome was complete eradication of intestinal metaplasia (CE-IM); secondary outcome was complete eradication of dysplasia (CE-D). RESULTS: A total of 171 SCT procedures were performed in 57 patients. The majority of patients were male (89.5%) with long-segment BE (93%; mean segment length 6.2 cm). Complete follow-up data was available for 56 of these 57 patients. 43.9% (25/57) of patients underwent radiofrequency ablation (RFA) during the course of treatment (e.g. after initiating SCT). 33.3% of patients (19/57) were RFA failures prior to SCT. Additionally, 68.4% (39/57) of patients underwent endoscopic resection (EMR) prior to SCT as part of our multimodal approach to treatment of BE dysplasia/neoplasia. Four patients (7%) are currently undergoing active ablation and/or EMR treatment. CE-IM was achieved in 75% (39/52) of patients, and CE-D in 98.1% (51/52). Mean duration of overall follow-up was 4.8 years, with mean CE-IM durability of 2.6 years. LIMITATIONS: Single-center only, retrospective study design. CONCLUSION: SCT-based multimodal endoscopic therapy can achieve very high CE-IM (75%) and CE-D (>98%) rates in a high-risk population with esophageal dysplasia and/or neoplasia.

Colonoscopy is the most commonly performed endoscopic procedure and overall is considered a low-risk procedure. However, adverse events (AEs) related to this routinely performed procedure for screening, diagnostic, or therapeutic purposes are an important clinical consideration. The purpose of this document from the American Society for Gastrointestinal Endoscopy's Standards of Practice Committee is to provide an update on estimates of AEs related to colonoscopy in an evidence-based fashion. A systematic review and meta-analysis of population-based studies was conducted for the 3 most common and important serious AEs (bleeding, perforation, and mortality). In addition, this document includes an updated systematic review and meta-analysis of serious AEs (bleeding and perforation) related to EMR and endoscopic submucosal dissection for large colon polyps. Finally, a narrative review of other colonoscopy-related serious AEs and those related to specific colonic interventions is included.

GOALS AND BACKGROUND: Two common endoscopic therapies for eradication of dysplastic Barrett's esophagus are radiofrequency ablation (RFA) and liquid nitrogen spray cryotherapy (LNC). There is no data comparing postprocedural pain. This study aimed to compare the incidence of postprocedural pain between the 2 ablation modalities. METHODS: This is a multicenter prospective study in which pain intensity scores and the presence of dysphagia were assessed immediately before and after treatment, 48 hours posttreatment and at 3 weeks posttreatment using validated instruments. RESULTS: Of 94 patients, 35 underwent LNC and 59 underwent RFA [36 with focal radiofrequency ablation (RFA-F) and 23 with circumferential radiofrequency ablation (RFA-C)]. Immediately posttreatment, patients in the LNC group reported an average Numeric Pain Scale score that was lower than in the RFA groups [LNC 0.41 vs. RFA-F 1.18 (P=0.026), LNC 0.41 vs. RFA-C 1.38 (P=0.010)]. These differences persisted at 48 hours posttreatment [LNC 0.76 vs. RFA-F 1.77 (P=0.013), LNC 0.76 vs. RFA-C 1.73 (P=0.018)]. The odds of pain after RFA were at least 5 times greater than after LNC [immediately posttreatment odds ratio, 5.26 (95% confidence interval, 1.85-14.29) and 48 h posttreatment odds ratio, 5.56 (95% confidence interval, 2.27-14.29)]. There was no difference in dysphagia after treatment in either group, at any time point (P=0.429). CONCLUSION: LNC was associated with less postprocedural pain when compared with RFA. These results help inform patients and physicians about the expected symptoms after ablative endotherapy.

INTRODUCTION: Pancreatic cancer is the fourth leading cause of cancer-related death in the USA. Early detection of pancreatic cancer may help improve patient survival. It has been hypothesized that acute idiopathic or chronic pancreatitis is associated with an increased risk of pancreatic cancer; however, these conditions may also represent an early manifestation of pancreatic cancer, rather than just being risk factors. Endoscopic ultrasound (EUS) is a sensitive diagnostic modality for the detection of small, early-stage pancreatic tumors. The aim of this study was to evaluate the diagnostic yield of EUS for pancreatic cancer in patients with acute idiopathic or chronic pancreatitis when cross-sectional imaging (CT and/or MRI) was negative for a mass lesion in the pancreas. METHODS: This study was an IRB-approved retrospective chart review conducted for the period of August 2005 to September 2018. Any patient presenting with acute idiopathic or chronic pancreatitis with a CT and/or MRI imaging negative for a pancreatic mass lesion that underwent an EUS during the study period was selected for inclusion. A retrospective review was performed to evaluate the outcomes of patients who had pancreatic cancer diagnosed from an EUS-FNA (fine needle aspiration) sample. Data were collected on patient demographics and clinical characteristics, inclusive of specific post-diagnosis treatment course. An "event rate" was calculated and is defined as the number of positive pancreatic cancer diagnoses on EUS-FNA from all patients presenting with acute idiopathic or chronic pancreatitis who underwent an EUS examination following a CT and/or MRI study negative for pancreatic mass lesion. RESULTS: A total of 565 patients met inclusion criteria, with 30 cases of confirmed pancreatic cancer diagnosed with EUS-FNA from this group. The event rate for EUS diagnosis of pancreatic cancer was 5.3%. The majority of patients (52.0%) diagnosed with cancer were stages I-II. CONCLUSIONS: Endoscopic ultrasound should be a routine part of the diagnostic algorithm when evaluating a patient with acute idiopathic or chronic pancreatitis of unclear etiology, particularly when cross-sectional imaging is negative for a mass lesion and clinical suspicion is high for neoplasia. Further prospective studies are needed to evaluate the role of EUS in this setting.

BACKGROUND & AIMS: Fluoroscopy during endoscopic retrograde cholangiopancreatography (ERCP) is increasingly performed by therapeutic endoscopists, many of whom have not received formal training in modulating fluoroscopy use to minimize radiation exposure. Exposure to ionizing radiation has significant health consequences for patients and endoscopists. We aimed to evaluate whether a 20-minute educational intervention for endoscopists would improve use of fluoroscopy and decrease ERCP-associated exposure to radiation for patients. METHODS: We collected data from 583 ERCPs, performed in California from June 2010 through November 2012; 331 were performed at baseline and 252 following endoscopist education. The educational intervention comprised a 20-minute video explaining best practices for fluoroscopy, coupled with implementation of a formal fluoroscopy time-out protocol before the ERCP was performed. Our primary outcome was the effect of the educational intervention on direct and surrogate markers of patient radiation exposure associated with ERCPs performed by high-volume endoscopists (HVEs) (200 or more ERCPs/year) vs low-volume endoscopists (LVEs) (fewer than 200 ERCPs/year). RESULTS: At baseline, total radiation dose and dose area product were significantly higher for LVEs, but there was no significant difference between HVEs and LVEs following education. Education was associated with significant reductions in median fluoroscopy time (48% reduction for HVEs vs 30% reduction for LVEs), total radiation dose (28% reduction for HVEs vs 52% for LVEs) and dose area product (35% reduction for HVEs vs 48% reduction for LVEs). All endoscopists significantly increased their use of low magnification and collimation following education. CONCLUSIONS: A 20-minute educational program with emphasis on ideal use of modifiable fluoroscopy machine settings results in an immediate and significant reduction in ERCP-associated patient radiation exposure for low-volume and high-volume endoscopists.

BACKGROUND & AIMS: It is not clear whether digital single-operator cholangioscopy (D-SOC) with electrohydraulic and laser lithotripsy is effective in removal of difficult biliary stones. We investigated the safety and efficacy of D-SOC with electrohydraulic and laser lithotripsy in an international, multicenter study of patients with difficult biliary stones. METHODS: We performed a retrospective analysis of 407 patients (60.4% female; mean age, 64.2 years) who underwent D-SOC for difficult biliary stones at 22 tertiary centers in the United States, United Kingdom, or Korea from February 2015 through December 2016; 306 patients underwent electrohydraulic lithotripsy and 101 (24.8%) underwent laser lithotripsy. Univariate and multivariable analyses were performed to identify factors associated with technical failure and the need for more than 1 D-SOC electrohydraulic or laser lithotripsy session to clear the bile duct. RESULTS: The mean procedure time was longer in the electrohydraulic lithotripsy group (73.9 minutes) than in the laser lithotripsy group (49.9 minutes; P < .001). Ducts were completely cleared (technical success) in 97.3% of patients (96.7% of patients with electrohydraulic lithotripsy vs 99% patients with laser lithotripsy; P = .31). Ducts were cleared in a single session in 77.4% of patients (74.5% by electrohydraulic lithotripsy and 86.1% by laser lithotripsy; P = .20). Electrohydraulic or laser lithotripsy failed in 11 patients (2.7%); 8 patients were treated by surgery. Adverse events occurred in 3.7% patients and the stone was incompletely removed from 6.6% of patients. On multivariable analysis, difficult anatomy or cannulation (duodenal diverticula or altered anatomy) correlated with technical failure (odds ratio, 5.18; 95% confidence interval, 1.26-21.2; P = .02). Procedure time increased odds of more than 1 session of D-SOC electrohydraulic or laser lithotripsy (odds ratio, 1.02; 95% confidence interval, 1.01-1.03; P < .001). CONCLUSIONS: In a multicenter, international, retrospective analysis, we found D-SOC with electrohydraulic or laser lithotripsy to be effective and safe in more than 95% of patients with difficult biliary stones. Fewer than 5% of patients require additional treatment with surgery and/or extracorporeal shockwave lithotripsy to clear the duct.

BACKGROUND AND AIMS: Dysphagia is a debilitating symptom in patients with inoperable esophageal cancer that contributes to poor quality of life and worsening nutritional status. The 2 most commonly used palliative modalities for dysphagia are radiation therapy and esophageal stent placement. However, radiation therapy is limited by adverse events (AEs) and total dose, and stent placement has a high rate of AEs, including reflux, migration, and chest pain. A relatively new modality of liquid nitrogen endoscopic spray cryotherapy has been described as salvage when other options have been exhausted and when patients are no longer receiving systemic therapy. We evaluated the safety and efficacy of cryotherapy as the primary modality for relieving dysphagia in inoperable esophageal cancer including patients receiving systemic cancer therapy. METHODS: This is a retrospective, multicenter, consecutive case series of 49 inoperable esophageal cancer patients undergoing palliative endoscopic cryotherapy at 4 specialized cancer centers from May 2014 to May 2016. The primary outcomes were change in dysphagia scores between pre- and postcryotherapy and AEs. Dysphagia was measured using a 5-point Likert scale: 0, no dysphagia; 1, dysphagia to solids; 2, dysphagia to semisolids; 3, dysphagia to liquids; 4, dysphagia to saliva. RESULTS: Thirty-nine men and 10 women with a mean age of 58 years underwent a total of 120 cryotherapy treatments. The mean dysphagia score improved significantly from 2.4 precryotherapy to 1.7 postcryotherapy (improvement of .7 points; P < .001). Minor AEs were seen in 6 of 120 (5.0%) cryotherapy treatments (1 intraprocedural and 5 postprocedural). In addition, 1 patient developed a severe intraprocedural AE of dilation-related perforation, whereas another patient developed a benign stricture requiring dilation. CONCLUSIONS: This preliminary retrospective study suggests that liquid nitrogen spray cryotherapy may be safe and effective for dysphagia palliation in inoperable esophageal cancer. Large prospective studies are needed to confirm these findings and identify patient and procedure characteristics associated with the greatest benefit.

BACKGROUND AND AIMS: Wide-area transepithelial sampling (WATS) with computer-assisted 3-dimensional analysis is a sampling technique that combines abrasive brushing of the Barrett's esophagus (BE) mucosa followed by neural network analysis to highlight abnormal-appearing cells. METHODS: We performed a randomized trial of referred BE patients undergoing surveillance at 16 medical centers. Subjects received either biopsy sampling followed by WATS or WATS followed by biopsy sampling. The primary outcome was rate of detection of high-grade dysplasia/esophageal adenocarcinoma (HGD/EAC) using WATS in conjunction with biopsy sampling compared with biopsy sampling alone using standard histopathologic criteria. Secondary aims included evaluating neoplasia detection rates based on the procedure order (WATS vs biopsy sampling first), of each procedure separately, and the additional time required for WATS. RESULTS: One hundred sixty patients (mean age, 63.4 years; 76% men; 95% white) completed the trial. The median circumferential and maximal BE extents were 1.0 cm (interquartile range: .0-5.0) and 4.0 cm (interquartile range, 2.0-8.0), respectively. The diagnostic yield for biopsy sampling alone was as follows: HGD/EAC, 7 (4.4%); low-grade dysplasia (LGD), 28 (17.5%); nondysplastic BE (NDBE), 106 (66.25%); and no BE, 19 (11.9%). The addition of WATS to biopsy sampling yielded an additional 23 cases of HGD/EAC (absolute increase, 14.4%; 95% confidence interval, 7.5%-21.2%). Among these 23 patients, 11 were classified by biopsy sampling as NDBE and 12 as LGD/indefinite for dysplasia (IND); 14 received biopsy sampling first and 9 WATS first (not significant) and most (n = 21; 91.7%) had a prior dysplasia history. WATS added an average of 4.5 minutes to the procedure. CONCLUSION: Results of this multicenter, prospective, randomized trial demonstrate that the use of WATS in a referral BE population increases the detection of HGD/EAC.
