RESUMEN
BACKGROUND & AIMS: Potassium-competitive acid blockers have documented efficacy for erosive esophagitis. We performed a randomized trial in United States subjects diagnosed with non-erosive reflux disease of vonoprazan vs placebo for 4 weeks, followed by a 20-week active-treatment extension. METHODS: Adult subjects with heartburn ≥4 days/week during screening without erosive esophagitis on endoscopy were randomized to placebo, vonoprazan 10 mg, or vonoprazan 20 mg. After 4 weeks, subjects on placebo were re-randomized to vonoprazan 10 mg or 20 mg, and those already on vonoprazan continued at the same dose for 20 weeks. Electronic diaries were completed twice daily. The primary endpoint was percentage of days without daytime or nighttime heartburn (24-hour heartburn-free days). RESULTS: Among 772 randomized subjects, the percentage of 24-hour heartburn-free days was 27.7% for placebo vs 44.8% for vonoprazan 10 mg (least squares mean difference, 17.1%; P < .0001) and 44.4% for vonoprazan 20 mg (least squares mean difference, 16.7%; P < .0001). Differences in percentage of subjects with a 24-hour heartburn-free day for vonoprazan 10 mg vs placebo and vonoprazan 20 mg vs placebo were 8.3% and 11.6% on day 1 and 18.1% and 23.2% on day 2. The mean/median percentages of 24-hour heartburn-free days over the extension period were similar across the 4 study arms: 61%-63%/76%-79%. CONCLUSIONS: Vonoprazan reduced heartburn symptoms in subjects diagnosed with non-erosive reflux disease, with the benefit appearing to begin as early as the first day of therapy. Treatment effect persisted after the initial 4-week placebo-controlled period throughout the 20-week extension period. The 2 vonoprazan doses (10 mg and 20 mg) were similar in efficacy.

RESUMEN
BACKGROUND: Wireless pH monitoring allows for a definitive GERD diagnosis, which is essential for optimal medical or surgical management of the patient. However, there is no guideline recommendation on whether prolonged pH testing (72 or 96 h) provides additional benefit when compared to the standard 48-h testing. We aimed to assess whether prolonged pH monitoring diagnoses more patients with GERD, as well as compare the DeMeester score to acid exposure time as diagnostic criteria for GERD. METHODS: This was a retrospective analysis of consecutive adult patients who underwent wireless esophageal pH monitoring between August 2018 and July 2021. The primary outcome was the additional diagnoses of GERD (predominant acid exposure pattern) in patients who underwent 48-h versus 96-h pH monitoring. Secondary outcomes included comparison of the DeMeester score to acid exposure time and internal agreement between the first and second 48-h blocks of a prolonged 96-h pH study. RESULTS: When comparing 48-h versus 96-h pH testing, the prolonged monitoring group was more likely to have a predominant reflux pattern and thus be diagnosed with definitive GERD by elevated DeMeester score (58.8% vs. 40.8%, p = 0.003) or acid exposure time > 6% (44.7% vs. 32.4%, p = 0.039). For patients who underwent prolonged testing, the results of monitoring beyond 48 h led to a clinically meaningful change in study interpretation in 24.8% of patients. The study data from Days 3 to 4 yielded only a 56.6% agreement with the first 2 days. CONCLUSIONS: In patients undergoing extended pH monitoring, almost half were found to have an abnormal pH study after a normal study on Day 1. An additional 25% of patients had a change in study interpretation by extending the study beyond 48 h. Our findings suggest only 48 h of pH monitoring will miss a diagnosis of GERD in a clinically important number of patients.

INTRODUCTION: High-resolution manometry (HRM) and functional lumen imaging probe (FLIP) are primary and/or complementary diagnostic tools for the evaluation of esophageal motility. We aimed to assess the interrater agreement and accuracy of HRM and FLIP interpretations. METHODS: Esophageal motility specialists from multiple institutions completed the interpretation of 40 consecutive HRM and 40 FLIP studies. Interrater agreement was assessed using intraclass correlation coefficient (ICC) for continuous variables and Fleiss' κ statistics for nominal variables. Accuracies of rater interpretation were assessed using the consensus of 3 experienced raters as the reference standard. RESULTS: Fifteen raters completed the HRM and FLIP studies. An excellent interrater agreement was seen in supine median integral relaxation pressure (ICC 0.96, 95% confidence interval 0.95-0.98), and a good agreement was seen with the assessment of esophagogastric junction (EGJ) outflow, peristalsis, and assignment of a Chicago Classification version 4.0 diagnosis using HRM (κ = 0.71, 0.75, and 0.70, respectively). An excellent interrater agreement for EGJ distensibility index and maximum diameter (0.91 [0.90-0.94], 0.92 [0.89-0.95]) was seen, and a moderate-to-good agreement was seen in the assignment of EGJ opening classification, contractile response pattern, and motility classification (κ = 0.68, 0.56, and 0.59, respectively) on FLIP. Rater accuracy for Chicago Classification version 4.0 diagnosis on HRM was 82% (95% confidence interval 78%-84%) and for motility diagnosis on FLIP Panometry was 78% (95% confidence interval 72%-81%). DISCUSSION: Our study demonstrates high levels of interrater agreement and accuracy in the interpretation of HRM and FLIP metrics and moderate-to-high levels for motility classification in FLIP, supporting the use of these approaches for primary or complementary evaluation of esophageal motility disorders.

BACKGROUND: Vonoprazan is a new acid-suppressing drug that received FDA approval in 2022. It reversibly inhibits gastric acid secretion by competing with the potassium ions on the luminal surface of the parietal cells (potassium-competitive acid blockers or P-CABs). Vonoprazan has been on the market for a short time and there are many clinical trials to support its clinical application. However, medical experience and comprehensive clinical data is still limited, especially on how and if, gastric histology is altered due to therapy. METHODS: A 12-week experiment trial with 30 Wistar rats was to assess the presence of gastrointestinal morphologic abnormalities upon administration of omeprazole and vonoprazan. At six weeks of age, rats were randomly assigned to one of 5 groups: (1) saline as negative control group, (2) oral omeprazole (40 mg/kg), as positive control group, (3) oral omeprazole (40 mg/kg) for 4 weeks, proceeded by 8 weeks off omeprazole, (4) oral vonoprazan (4 mg/kg), as positive control group, and (5) oral vonoprazan (4 mg/kg) for 4 weeks, proceeded by 8 weeks off vonoprazan. RESULTS: We identified non-inflammatory alterations characterized by parietal (oxyntic) cell loss and chief (zymogen) cell hyperplasia and replacement by pancreatic acinar cell metaplasia (PACM). No significant abnormalities were identified in any other tissues in the hepatobiliary and gastrointestinal tracts. CONCLUSION: PACM has been reported in gastric mucosa, at the esophagogastric junction, at the distal esophagus, and in Barrett esophagus. However, the pathogenesis of this entity is still unclear. Whereas some authors have suggested that PACM is an acquired process others have raised the possibility of PACM being congenital in nature. Our results suggest that the duration of vonoprazan administration at a dose of 4 mg/kg plays an important role in the development of PACM.

Gastroesophageal reflux disease (GERD) continues to be among the most common diseases seen by gastroenterologists, surgeons, and primary care physicians. Our understanding of the varied presentations of GERD, enhancements in diagnostic testing, and approach to patient management have evolved. During this time, scrutiny of proton pump inhibitors (PPIs) has increased considerably. Although PPIs remain the medical treatment of choice for GERD, multiple publications have raised questions about adverse events, raising doubts about the safety of long-term use and increasing concern about overprescribing of PPIs. New data regarding the potential for surgical and endoscopic interventions have emerged. In this new document, we provide updated, evidence-based recommendations and practical guidance for the evaluation and management of GERD, including pharmacologic, lifestyle, surgical, and endoscopic management. The Grading of Recommendations, Assessment, Development, and Evaluation system was used to evaluate the evidence and the strength of recommendations. Key concepts and suggestions that as of this writing do not have sufficient evidence to grade are also provided.

OBJECTIVE: We aimed to quantify the contribution of pneumoperitoneum on compliance of the esophagogastric junction (EGJ) during anti-reflux surgery. BACKGROUND: Compliance of the EGJ is reduced with anti-reflux surgery. EndoFLIP® planimetry can be used to assess dynamic changes of EGJ compliance intraoperatively. It is unclear how pneumoperitoneum impacts intraoperative measurements by EndoFLIP® and the implications thereof on validity of the results. Therefore, determining variability in EndoFLIP® measurements based on pneumoperitoneum is warranted to establish guidelines to interpret clinical outcomes. METHODS: Primary anti-reflux surgery was performed on 39 consecutive patients with pathologic reflux. Intraoperative EGJ measurements including distensibility index (DI), cross-sectional area (CSA), and intrabag pressure were collected using EndoFLIP® at 0, 10, and 15 mmHg of intraperitoneal pressure. Data were acquired pre-procedure, post-hiatal hernia repair, and post-LES augmentation with fundoplications. RESULTS: Patients underwent Nissen (13.2%), Toupet (68.4%), LINX (10.5%), or Hill-fundoplications (7.9%). There was no difference between 0 and 10 mmHg of pneumoperitoneum in CSA, pressure, or DI measurements pre-procedure; however, there was a difference between 0 and 15 mmHg in pressure (p = 0.016) and DI (p = 0.023) measurements. After LES augmentation, 10 mmHg intraperitoneal pressure reduced DI, though the absolute difference is small (2.0 vs. 1.5 mm2/mmHg, p = 0.002). CONCLUSION: Pneumoperitoneum affected EGJ distensibility at 15 mmHg, but not 10 mmHg, of insufflation prior to anti-reflux procedures. After anti-reflux surgery, there was a significant variance between 0 and 10 mmHg of pneumoperitoneum in pressure and distensibility. The change in pressure appears linear and needs to be considered if procedural modifications are performed based on intraoperative findings and when evaluating clinical outcomes.

BACKGROUND: Anti-reflux surgery (ARS) has known long-term complications, including dysphagia, bloat, and flatulence, among others. The factors affecting the development of post-operative dysphagia are poorly understood. We investigated the correlation of intra-operative esophagogastric junction (EGJ) characteristics and procedure type with post-operative dysphagia following ARS. METHODS: Robotic ARS was performed on 197 consecutive patients with pathologic reflux utilizing EndoFLIP™ technology. Intraoperative EGJ measurements including distensibility index (DI), cross-sectional area (CSA), and high-pressure zone (HPZ) length were collected. Dysphagia was assessed pre-operatively and at 3 months post-operatively. RESULTS: The median pre-operative DI for all procedures was 2.6 (IQR 1.6-4.5) mm2/mmHg. There was no difference in post-operative DI between procedures [Hill: 0.9 (IQR 0.7-1.1) mm2/mmHg, Nissen: 1.0 (IQR 0.7-1.4) mm2/mmHg, Toupet: 1.2 (IQR 0.8-1.5) mm2/mmHg, Linx: 1.0 (IQR 0.7-1.2) mm2/mmHg, p = 0.24], whereas post-operative HPZ length differed by augmentation type [Hill: 3 (IQR 2.8-3) cm, Nissen: 3.5 (IQR 3-3.5) cm, Toupet: 3 (IQR 2.5-3.5) cm, Linx: 2.5 (IQR 2.5-3) cm, p = 0.032]. Eighty-nine patients (45.2%) had pre-operative dysphagia. Thirty-two patients (27.6%) reported any dysphagia at their 3-month post-operative visit and 12 (10.3%) developed new or worsening post-operative dysphagia [Hill: 2/18 (11.1%), Nissen: 2/35 (5.7%), Toupet: 4/54 (7.4%), Linx: 4/9 (44.4%), p = 0.006]. The median pre-operative and post-operative DI of patients who developed new or worsening dysphagia was 2.0 (IQR 0.9-3.8) mm2/mmHg and 1.2 (IQR 1.0-1.8) mm2/mmHg, respectively, and that of those who did not was 2.5 (IQR 1.6-4.0) mm2/mmHg and 1.0 (IQR 0.7-1.4) mm2/mmHg (p = 0.21 and 0.16, respectively). CONCLUSIONS: Post-operative DI was similar between procedures, and there was no correlation with new or worsening post-operative dysphagia. Linx placement was associated with higher rates of new or worsening post-operative dysphagia despite a shorter post-procedure HPZ length and similar post-operative DI when compared to other methods of LES augmentation.

BACKGROUND: Hiatal hernia re-approximation during index anti-reflux surgery (ARS) contributes approximately 80% of overall change in distensibility index (DI) and, potentially, compliance of the gastroesophageal (GEJ), while sphincter augmentation contributes approximately 20%. Whether this is seen in re-operative ARS is unclear. We quantify the physiologic parameters of the GEJ at each step of robotic re-operative ARS and compare these to index ARS. METHODS: Robotic ARS with hiatal hernia repair was performed on 195 consecutive patients with pathologic reflux utilizing EndoFLIP™, of which 26 previously had ARS. Intra-operative GEJ measurements, including cross-sectional area (CSA), pressure, DI, and high-pressure zone (HPZ) length were collected pre-repair, post-diaphragmatic re-approximation, post-mesh placement, and post-lower-esophageal sphincter (LES) augmentation. RESULTS: Both cohorts were similar by sex and BMI and underwent similar procedures. The re-operative cohort was older (60.6 ± 15.3 vs. 52.7 ± 16.2 years, p = 0.03), had more frequent pre-operative dysphagia (69.2% vs. 42.6%, p = 0.01) and esophageal dysmotility on barium swallow (75.0% vs. 35.0%, p < 0.001) but lower rates of hiatal hernia on endoscopy (30.8% vs. 68.7%, p < 0.001) compared to index procedures. Among the re-operative cohort, the CSA decreased by 34 (IQR - 80, - 15) mm2 and DI 1.1 (IQR - 2.4, - 0.6) mm2/mmHg (both p < 0.001). Pressure increased by 11.2 (IQR 4.7, 14.9) mmHg and HPZ by 1.5 (1,2) cm (both p < 0.001). These changes were similar to those seen in index ARS. Diaphragmatic re-approximation contributed to a greater percentage of overall change to the GEJ than did the augmentation procedure, with 72% of the change in DI occurring during hiatal closure, similar to that seen during index ARS. CONCLUSIONS: During re-operative ARS, dynamic intra-operative monitoring can quantify the effects of each operative step on GEJ physiologic parameters. Diaphragmatic re-approximation appears to have a greater effect on GEJ physiology than does LES-sphincter augmentation during both index and re-operative ARS.

INTRODUCTION: Functional luminal imaging probe (FLIP) panometry can evaluate esophageal motility in response to sustained esophageal distension at the time of sedated endoscopy. This study aimed to describe a classification of esophageal motility using FLIP panometry and evaluate it against high-resolution manometry (HRM) and Chicago Classification v4.0 (CCv4.0). METHODS: Five hundred thirty-nine adult patients who completed FLIP and HRM with a conclusive CCv4.0 diagnosis were included in the primary analysis. Thirty-five asymptomatic volunteers ("controls") and 148 patients with an inconclusive CCv4.0 diagnosis or systemic sclerosis were also described. Esophagogastric junction (EGJ) opening and the contractile response (CR) to distension (i.e., secondary peristalsis) were evaluated with a 16-cm FLIP during sedated endoscopy and analyzed using a customized software program. HRM was classified according to CCv4.0. RESULTS: In the primary analysis, 156 patients (29%) had normal motility on FLIP panometry, defined by normal EGJ opening and a normal or borderline CR; 95% of these patients had normal motility or ineffective esophageal motility on HRM. Two hundred two patients (37%) had obstruction with weak CR, defined as reduced EGJ opening and absent CR or impaired/disordered CR, on FLIP panometry; 92% of these patients had a disorder of EGJ outflow per CCv4.0. DISCUSSION: Classifying esophageal motility in response to sustained distension with FLIP panometry parallels the swallow-associated motility evaluation provided with HRM and CCv4.0. Thus, FLIP panometry serves as a well-tolerated method that can complement, or in some cases be an alternative to HRM, for evaluating esophageal motility disorders.

OBJECTIVE: To quantify the contribution of key steps in antireflux surgery on compliance of the EGJ. BACKGROUND: The lower esophageal sphincter and crural diaphragm constitute the intrinsic and extrinsic sphincters of the EGJ, respectively. Interventions to treat reflux attempt to restore the integrity of the EGJ. However, there are limited data on the relative contribution of critical steps during antireflux procedures to the functional integrity of the EGJ. METHODS: Primary antireflux surgery was performed on 100 consecutive patients with pathologic reflux. Intraoperative EGJ measurements including distensibility index (DI), cross-sectional area (CSA), and HPZ length were collected using EndoFLIP. Data was acquired pre-repair, post-diaphragmatic re-approximation with sub-diaphragmatic EGJ relocation, and post-sphincter augmentation. RESULTS: Patients underwent Nissen (45%), Toupet (44%), or LINX (11%). After diaphragmatic re-approximation, DI decreased by a median 0.77âmm2/mm Hg [95%-confidence interval (CI): -0.99, -0.58; P < 0.0001], CSA decreased 16.0 mm2 (95%-CI: -20.0, -8.0; P < 0.0001), whereas HPZ length increased 0.5âcm (95%-CI: 0.5, 1.0; P < 0.0001). After sphincter augmentation, DI decreased 0.14âmm2/mm Hg (95%-CI: -0.30, -0.04; P = 0.0005) and CSA decreased 5.0 mm2 (95%-CI: -10.0, 1.0; P = 0.0.0015), whereas HPZ length increased 0.5âcm (95%-CI: 0.50, 0.54; P < 0.0001). Diaphragmatic re-approximation had a higher percent contribution to distensibility (79% vs 21%), CSA (82% vs 18%), and HPZ (60% vs 40%) than sphincter augmentation. CONCLUSION: Dynamic intraoperative monitoring demonstrates that diaphragmatic re-approximation and sub-diaphragmatic relocation has a greater effect on EGJ compliance than sphincter augmentation. As such, antireflux procedures should address both for optimal improvement of EGJ physiology.

INTRODUCTION: There is marked variability in colonoscopy quality, limiting its effectiveness in colorectal cancer prevention. Multiple indicators have been established as markers for colonoscopy quality; however, there are conflicting data on the effects of quality reporting programs on endoscopist performance. In this study, we investigate the impact of a multicenter quarterly report card initiative on colonoscopy quality metric performance. METHODS: Data were collected from 194 endoscopists at 10 participating sites throughout New York City using a Qualified Clinical Data Registry from January 2013 to December 2014. Adenoma detection rate (ADR), cecal intubation rate, withdrawal time, bowel preparation quality and appropriate interval recommendations were tracked. Report cards were distributed to each site on a quarterly basis and technical assistance was provided as needed. Performance trends were analyzed using the Cochran-Armitage trend and analysis of variance tests. RESULTS: 37,258 screening colonoscopies were performed during the study period. There was a positive performance trend for ADR over time from the first quarter of 2013 to the last quarter of 2014 (15.6-25.7%; p < 0.001). There were also increases in cecal intubation rates (78.2-92.6%; p < 0.001), bowel preparation adequacy rates (77.5-92.8%; p < 0.001), and adherence to appropriate screening intervals (28.0-55.0%; p < 0.001). There was no clinically significant change in mean withdrawal time. CONCLUSIONS: The implementation of a quarterly report card initiative resulted in statistically significant improvements in adenoma detection, cecal intubation, bowel preparation adequacy rates, and appropriate recommended screening intervals.

PURPOSE OF REVIEW: The specialty of gastroenterology has evolved such that there are now multiple areas of "superspecialty" within the field. Interest in "esophagology" has expanded as options for medical therapy, advanced optics, motility testing and reflux monitoring, and minimally invasive and endoscopic therapeutics have grown. For a multitude of reasons, academic and private practices alike are looking to expand in this growing superspecialty. RECENT FINDINGS: Several articles offer criteria for competency in manometry. This article discusses in detail multiple options for developing skills in diagnosis and treatment of esophageal disease with "tips for the budding esophagologist."

BACKGROUND: Current guidelines recommend starting colorectal cancer (CRC) surveillance 8-10 years after inflammatory bowel disease (IBD) onset. Recent studies report that the incidence of CRC within 8-10 years of IBD onset (i.e., early CRC) ranges from 12 to 42%. AIMS: To describe the current prevalence of early CRC in a tertiary care center IBD cohort with CRC and to identify associated risk factors. METHODS: We performed a single-center observational study of IBD patients diagnosed with CRC from 2005 to 2015. We compared characteristics of patients with early CRC (diagnosis of CRC within 8 years of initial IBD onset) to those with CRC diagnosed later in their IBD course. RESULTS: Ninety-three patients met inclusion criteria. Eleven (11.8%) patients developed CRC within 8 years of initial IBD onset. On multivariable logistic regression, age greater than 28 at IBD onset (adjusted OR 12.0; 95% CI 2.30, 62.75) and tobacco use (adjusted OR 8.52; 95% CI 1.38, 52.82) were significant predictors of early CRC. A validation cohort confirmed calibration and discrimination of the model. CONCLUSIONS: One out of every eight IBD patients with CRC developed their malignancy prior to the currently recommended timeframe for the initiation of surveillance colonoscopy. IBD onset at 28 years or older and tobacco use were identified as predictors of early CRC. Early CRC should be considered in discussions of cancer surveillance in this population. Prospective cohort studies are necessary to further analyze the impact of early CRC in IBD.

BACKGROUND & AIMS: Endoscopic ultrasound with fine-needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the gastrointestinal tract. Fine-needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB. METHODS: This is a multicenter, prospective randomized clinical trial from 6 large tertiary care centers. Patients referred for tissue sampling of solid lesions were randomized to either FNA or FNB of the target lesion. Demographics, size, location, number of needle passes, and final diagnosis were recorded. RESULTS: After enrollment, 135 patients were randomized to FNA (49.3%), and 139 patients were randomized to FNB (50.7%).The following lesions were sampled: mass (n = 210, 76.6%), lymph nodes (n = 46, 16.8%), and submucosal tumors (n = 18, 6.6%). Final diagnosis was malignancy (n = 192, 70.1%), reactive lymphadenopathy (n = 30, 11.0%), and spindle cell tumors (n = 24, 8.8%). FNA had a diagnostic yield of 91.1% compared with 88.5% for FNB (P = .48). There was no difference between FNA and FNB when stratified by the presence of on-site cytopathology or by type of lesion sampled. A median of 1 needle pass was needed to obtain a diagnostic sample for both needles. CONCLUSIONS: FNA and FNB obtained a similar diagnostic yield with a comparable number of needle passes. On the basis of these results, there is no significant difference in the performance of FNA compared with FNB in the cytologic diagnosis of solid lesions adjacent to the gastrointestinal tract.

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.

BACKGROUND: Treatment for achalasia has traditionally been Heller myotomy (HM). Despite its excellent efficacy rate, a number of patients remain symptomatic post-procedure. Limited data exist as to the best management for recurrence of symptoms post-HM. We present an international, multicenter experience evaluating the efficacy and safety of post-HM peroral endoscopic myotomy (POEM). METHODS: Patients who underwent POEM post-HM from 13 centers from January 2012 to January 2017 were included as part of a prospective registry. Technical success was defined as successful completion of the myotomy. Clinical success was defined as an Eckardt score of ≤3 on 12-month follow up. Adverse events (AE) including anesthesia-related, operative, and postoperative complications were recorded. RESULTS: Fifty-one patients were included in the study (mean age 54.2, 47% male). Technical success was achieved in 100% of patients. Clinical success on long-term follow up was achieved in 48 patients (94%), with a mean change in Eckardt score of 6.25. Seven patients (13%) had AE: six experienced periprocedural mucosal defect treated endoscopically and two patients developed mediastinitis treated conservatively. CONCLUSION: For patients with persistent symptoms after HM, POEM is a safe salvation technique with good short-term efficacy. As a result of the challenge associated with repeat HM, POEM might become the preferred technique in this patient population. Further studies with longer follow up are needed.

BACKGROUND: Although screening for colorectal cancer (CRC) is a widely accepted concept nationally and screening rates are increasing, there are differences in screening rates between states and within states. METHODS: In an effort to increase screening rates and ensure equal access with respect to race/ethnicity, the New York City Department of Health and Mental Hygiene formed a coalition of stakeholders in 2003, with its primary focus on colonoscopy, to develop and implement strategies across the city to achieve this goal. RESULTS: From a screening colonoscopy rate of only 42% in 2003, these concerted efforts contributed to achieving a screening rate of 62% by 2007 and a screening rate of almost 70% in 2014 with the elimination of racial and ethnic disparities. CONCLUSIONS: This article provides details of how this program was successfully conceived, implemented, and sustained in the large urban population of New York City. The authors hope that by sharing the many elements involved and the lessons learned, they may help other communities to adapt these experiences to their own environments so that CRC screening rates can be maximized.

BACKGROUND & AIMS: Colon capsule endoscopy (CCE) is a noninvasive technique used to explore the colon without sedation or air insufflation. A second-generation capsule was recently developed to improve accuracy of detection, and clinical use has expanded globally. We performed a systematic review and meta-analysis to assess the accuracy of CCE in detecting colorectal polyps. METHODS: We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and other databases from 1966 through 2015 for studies that compared accuracy of colonoscopy with histologic evaluation with CCE. The risk of bias within each study was ascertained according to Quality Assessment of Diagnostic Accuracy in Systematic Reviews recommendations. Per-patient accuracy values were calculated for polyps, overall and for first-generation (CCE-1) and second-generation (CCE-2) capsules. We analyzed data by using forest plots, the I2 statistic to calculate heterogeneity, and meta-regression analyses. RESULTS: Fourteen studies provided data from 2420 patients (1128 for CCE-1 and 1292 for CCE-2). CCE-2 and CCE-1 detected polyps >6 mm with 86% sensitivity (95% confidence interval [CI], 82%-89%) and 58% sensitivity (95% CI, 44%-70%), respectively, and 88.1% specificity (95% CI, 74.2%-95.0%) and 85.7% specificity (95% CI, 80.2%-90.0%), respectively. CCE-2 and CCE-1 detected polyps >10 mm with 87% sensitivity (95% CI, 81%-91%) and 54% sensitivity (95% CI, 29%-77%), respectively, and 95.3% specificity (95% CI, 91.5%-97.5%) and 97.4% specificity (95% CI, 96.0%-98.3%), respectively. CCE-2 identified all 11 invasive cancers detected by colonoscopy. CONCLUSIONS: The sensitivity in detection of polyps >6 mm and >10 mm increased substantially between development of first-generation and second-generation colon capsules. High specificity values for detection of polyps by CCE-2 seem to be achievable with a 10-mm cutoff and in a screening setting.
