RESUMEN
BACKGROUND & AIMS: Next-generation sequencing (NGS) of pancreatic cyst fluid is a useful adjunct in the assessment of patients with pancreatic cyst. However, previous studies have been retrospective or single institutional experiences. The aim of this study was to prospectively evaluate NGS on a multi-institutional cohort of patients with pancreatic cyst in real time. METHODS: The performance of a 22-gene NGS panel (PancreaSeq) was first retrospectively confirmed and then within a 2-year timeframe, PancreaSeq testing was prospectively used to evaluate endoscopic ultrasound-guided fine-needle aspiration pancreatic cyst fluid from 31 institutions. PancreaSeq results were correlated with endoscopic ultrasound findings, ancillary studies, current pancreatic cyst guidelines, follow-up, and expanded testing (Oncomine) of postoperative specimens. RESULTS: Among 1933 PCs prospectively tested, 1887 (98%) specimens from 1832 patients were satisfactory for PancreaSeq testing. Follow-up was available for 1216 (66%) patients (median, 23 months). Based on 251 (21%) patients with surgical pathology, mitogen-activated protein kinase/GNAS mutations had 90% sensitivity and 100% specificity for a mucinous cyst (positive predictive value [PPV], 100%; negative predictive value [NPV], 77%). On exclusion of low-level variants, the combination of mitogen-activated protein kinase/GNAS and TP53/SMAD4/CTNNB1/mammalian target of rapamycin alterations had 88% sensitivity and 98% specificity for advanced neoplasia (PPV, 97%; NPV, 93%). Inclusion of cytopathologic evaluation to PancreaSeq testing improved the sensitivity to 93% and maintained a high specificity of 95% (PPV, 92%; NPV, 95%). In comparison, other modalities and current pancreatic cyst guidelines, such as the American Gastroenterology Association and International Association of Pancreatology/Fukuoka guidelines, show inferior diagnostic performance. The sensitivities and specificities of VHL and MEN1/loss of heterozygosity alterations were 71% and 100% for serous cystadenomas (PPV, 100%; NPV, 98%), and 68% and 98% for pancreatic neuroendocrine tumors (PPV, 85%; NPV, 95%), respectively. On follow-up, serous cystadenomas with TP53/TERT mutations exhibited interval growth, whereas pancreatic neuroendocrine tumors with loss of heterozygosity of ≥3 genes tended to have distant metastasis. None of the 965 patients who did not undergo surgery developed malignancy. Postoperative Oncomine testing identified mucinous cysts with BRAF fusions and ERBB2 amplification, and advanced neoplasia with CDKN2A alterations. CONCLUSIONS: PancreaSeq was not only sensitive and specific for various pancreatic cyst types and advanced neoplasia arising from mucinous cysts, but also reveals the diversity of genomic alterations seen in pancreatic cysts and their clinical significance.

BACKGROUND AND AIMS: Video capsule endoscopy (VCE) is valuable for assessing conditions like gastrointestinal bleeding, anemia, and inflammatory bowel disease. Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are prescribed for diabetes and weight loss, with their pharmacologic effects including delaying gastric emptying. This study investigates the impact of GLP-1 RA usage on VCE outcomes in patients with diabetes. METHODS: This retrospective cohort study involves patients with diabetes undergoing VCE while on GLP-1 RA, matched 1:1 ratio with controls based on demographics and diabetes related factors, who are not on GLP-RA. The primary outcome is gastric transit time in VCE studies, with secondary outcome being incomplete small bowel evaluation and the small bowel transit time. RESULTS: In the 68 GLP-1 RA patient cohort, five (7%) experienced VCE failure to pass through the stomach, while all controls passed successfully (p=0.06). GLP-1 RA patients had longer gastric transit time (99.3 ± 134.2 minutes) compared to controls (25.3 ± 31.6 minutes, p <0.001). Multivariate analysis revealed GLP-1 RA usage was associated with increased gastric transit time by 74.5 minutes (CI: 33.8-115.2, p <0.001) compared to controls, after adjusting on relevant factors. Sixteen GLP-1 RA patients (23.5%) experienced incomplete passage of the VCE through the small intestine, a significantly higher rate compared to three patients in the control group (4.4%) (p<0.01). CONCLUSIONS: GLP-1 RA usage is associated with prolonged gastric transit time and a higher rate of incomplete small bowel evaluation during VCE. Future studies may be crucial for evaluating strategies to mitigate these effects.
RESUMEN
BACKGROUND: Double balloon enteroscopy remains a resource and time-intensive procedure that is not available in many endoscopy units. AIMS: We aimed to identify variables impacting the speed and completion of double balloon enteroscopy. METHODS: We retrospectively reviewed 550 patients. Using a mean time and distance for both the antegrade and retrograde approach, we determined the procedure speed and assessed factors that influenced it. In addition, we assessed the factors that contributed to a complete double balloon enteroscopy. RESULTS: A total of 386 antegrade and 164 retrograde double balloon enteroscopies were performed. Greater than 10 AVMs requiring treatment was a negative predictor (AOR 0.25, CI 0.11-0.51, p < 0.001), whereas age greater than 60 years (AOR 2.66, CI 1.18-6.65, p = 0.025) was a positive predictor of a fast antegrade enteroscopy. For retrograde, prior abdominal surgery was the only factor that trended to significance (AOR 0.38, CI 0.14-0.99, p = 0.052). A total of 120 combined procedures were performed. Female gender (AOR 2.62, CI 1.16-6.24, p = 0.02), history of prior abdominal surgery (AOR 0.31, CI 0.13-0.70, p = 0.006) and Boston bowel pre-preparation score of greater than 6 (AOR 4.50, CI 1.59-14.30, p = 0.006) were the only significant predictors of a complete procedure. CONCLUSION: By applying double balloon enteroscopy speed, a novel method of measuring procedure efficiency, we were able to more reliably identify the factors that will negatively impact the speed and success of the procedure.

PURPOSE OF REVIEW: Several recent studies have corroborated a strong association between diet and gastric cancer risk; investigators have also identified dietary factors that protect against gastric cancer. This review summarizes the literature on this topic and guides future research directions. RECENT FINDINGS: High-salt intake disrupts the gastric mucosal defense barrier, promoting Helicobacter pylori colonization and penetration of other carcinogenic compounds. Processed foods, processed meats, red meat, alcohol, foods with high dietary fat, and dietary cholesterol increase the risk of gastric carcinogenesis. On the other hand, increased consumption of fruits, vegetables, whole grains, nuts, and a low-salt diet may offer a protective effect. SUMMARY: Despite decreases in gastric cancer incidence because of increased identification and treatment of H. pylori , gastric cancer remains one of the most common cancers worldwide with a high mortality rate. This disturbing statistic highlights the importance of reducing and eliminating other risk factors for gastric cancer. There is a strong body of evidence that alcohol, processed foods, high salt intake, high fat intake, and foods with animal products (meats, eggs, and dairy) increase the risk of gastric cancer. A diet that is high in whole grains, fruits, vegetables, nuts and is low in salt may reduce the risk of gastric cancer.

Postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) is the most common complication of endoscopic retrograde cholangiopancreatography pancreatitis (ERCP). No randomized controlled trial (RCT) has compared the efficacy of the American Society of Gastrointestinal Endoscopy and European Society of Gastrointestinal Endoscopy recommended interventions for PEP prevention. We assessed the effectiveness of these interventions using network meta-analysis. PubMed, EMBASE, and Cochrane databases were searched to identify RCTs investigating guideline-recommended interventions and their combinations [rectal nonsteroidal anti-inflammatory drugs (NSAIDs): indomethacin or diclofenac, pancreatic stent (PS), aggressive hydration (AH), sublingual nitrate) for PEP prevention. We performed direct and Bayesian network meta-analysis, and the surface under the cumulative ranking curve to rank interventions. Subgroup network meta-analysis for high-risk populations was also performed. We identified a total of 38 RCTs with 10 different interventions. Each intervention was protective against PEP on direct and network meta-analysis compared with controls. Except AH+diclofenac and NSAIDs+ sublingual nitrate, AH+indomethacin was associated with a significant reduction in risk of PEP compared with PS [odds ratio (OR), 0.09; credible interval (CrI), 0.003-0.71], indomethcin+PS (OR, 0.09; CrI, 0.003-0.85), diclofenac (OR, 0.09; CrI, 0.003-0.65), AH (OR, 0.09; CrI, 0.003-0.65), sublingual nitrate (OR, 0.07; CrI, 0.002-0.63), and indomethacin (OR, 0.06; CrI, 0.002-0.43). AH with either rectal NSAIDs or sublingual nitrate had similar efficacy. AH+indomethacin was the best intervention for preventing PEP with 95.3% probability of being ranked first. For high-risk patients, although the efficacy of PS and indomethacin were comparable, PS had an 80.8% probability of being ranked first. AH+indomethacin seems the best intervention for preventing PEP. For high-risk patients, PS seems the most effective strategy. The potential of combination of interventions need to be explored further.

BACKGROUND: Several professional society guidelines suggest holding antiplatelet agents before high-risk procedures. However, there is lack of high-grade evidence to support the recommendation as most of the studies have been single center with small sample sizes. We aimed to perform the first systematic review and meta-analysis comparing dual antiplatelet therapy (DAPT) versus aspirin alone in terms of postendoscopic retrograde cholangiopancreatography (ERCP) bleeding. METHODS: Three independent reviewers performed a comprehensive review of all original articles published from inception to May 2020, evaluating the post-ERCP bleeding rate in setting of DAPT. Primary outcomes were the overall post-ERCP bleeding rate with the use of dual antiplatelet therapy; comparison of post-ERCP bleeding rate in patients with DAPT versus aspirin alone. Secondary outcomes were comparison of immediate and delayed post-ERCP bleeding outcomes in the 2 cohorts. RESULTS: Six studies were included after a thorough search was concluded using the key words. The pooled analysis of studies revealed an overall post-ERCP bleeding rate of 5.7% (95% confidence interval: 3-10.6) on sustained DAPT. Post-ERCP bleeding in DAPT Cohort was not significantly higher as compared with aspirin only Cohort (odds ratio: 1.14, 95% confidence interval: 0.46-2.81). The immediate bleeding and delayed bleeding rates cannot be generalized due to low number of studies. CONCLUSIONS: The first systematic review and meta-analysis showed that post-ERCP bleeding rates are not significantly higher in DAPT cohort as compared with aspirin alone. Therefore, the risk of bleeding is less likely related to the antiplatelet agents and more likely related to the procedure itself.

Luminal strictures can occur as part of many different gastrointestinal (GI) disorders anywhere along the GI tract and affect all age groups. The end goal of managing any stricture is to re-establish an adequate and durable luminal patency that is sufficient to resolve the presenting clinical symptoms. Treatment options can be generally categorized into medical, endoscopic, and surgical. However, within each of these categories, multiple different options are available. Therefore, choosing the best treatment modality is often challenging and depends on multiple factors including the type, location, and complexity of the stricture, as well as the preference of the treating physician. In this article, we will review the most current literature regarding foregut strictures, particularly esophageal and gastric, beyond dilation.

BACKGROUND: Sclerosing mesenteritis is a rare condition characterized by chronic inflammation and fibrotic changes of the mesentery. AIMS: To determine the long-term management and outcomes of patients with sclerosing mesenteritis. METHODS: Patients with biopsy-proven sclerosing mesenteritis at the Mayo Clinic between January 2006 and December 2016 were identified. Clinical data were collected retrospectively. RESULTS: One hundred and three patients were identified, median age 68.0 years (range 35.0-85.3). Most patients were symptomatic (87.4%) at presentation. Patients received no treatment (52.4%), medical therapy (42.7%) or surgery (4.9%) on initial diagnosis. The most common initial regimens were prednisone plus tamoxifen (41.9%), prednisone alone (23.3%), and prednisone plus colchicine (11.6%) with 55.6%, 57.2%, and 60% of patients improving, respectively, p = 0.85 for a difference in response rates. At least half of the patients responded to prednisone plus tamoxifen, prednisone plus colchicine, or prednisone alone at 6.0, 7.2, and 8.4 months, respectively. At a median follow-up of 45.6 months (95% CI 24.1-69.7), 65.4% of patients were receiving medical therapy. Of those receiving tamoxifen-based, steroid-based, or steroid-sparing regimens, 100%, 87.5%, and 77.8% had improved by their last follow-up appointment respectively, p = 0.15. CONCLUSION: Prednisone plus colchicine has a similar efficacy to prednisone plus tamoxifen for the initial and long-term treatment of sclerosing mesenteritis. The majority of patients were initiated on medical therapy over the long term with most reporting symptomatic improvement within a year. Death from SM was rare.

BACKGROUND: The diagnosis of isolated small bowel Crohn's disease (CD) can be challenging. Symptoms are non-specific and both imaging and capsule endoscopy (CE) may be misleading as several diseases may mimic CD. Double balloon enteroscopy (DBE) allows a more extensive endoscopic and histologic evaluation of the small bowel. Our aim was to describe the diagnostic utility and impact of DBE on management of patients with known CD and in patients with suspected/rule-out CD. METHODS: Retrospective review of our institution's DBE database from February 2009 to May 2013. Adult patients referred for DBE for further evaluation of known or suspected CD (due to symptoms, abnormal imaging and/or CE) were included. Patient demographics, clinical characteristics, imaging and CE results, prior DBE, indication for DBE, DBE findings, DBE adverse events, pathology findings, final diagnosis, treatment prior and post DBE and follow-up DBE were abstracted from the electronic medical record. RESULTS: A total of 108 patients were included, 61 (56%) females, mean age 52 years (range 20-83). Indications for DBE included: disease activity assessment/therapeutic in 10 patients with established diagnosis of CD and for diagnostic purposes in 98 patients with suspected CD (31 patients due to abnormal imaging, 29 due to abnormal CE and 26 due to both abnormal imaging and CE). Upper, lower, bidirectional upper and lower, and stomal DBE were performed in 21, 24, 62 and 1 patients, respectively. DBE revealed active disease in 8/10 patients with known CD with one patient undergoing dilation of a stricture. Changes in management were recommended for all patients with active disease - start thiopurine (2), optimize thiopurine dose (1), start biologics (3) change biologics (1), systemic steroids (1) and budesonide (1). The patient who underwent stricture dilation ultimately required surgery. A definitive diagnosis of CD (both endoscopic and histologic) was reached in only 39/98 (40%) patients who were referred for suspected CD. Changes in management were recommended in 32/39 (82%) patients. Interestingly, 24/98 patients had been diagnosed with CD at outside institutions and were recommended to initiate therapy for CD. Of these, CD was confirmed in only 15/24 (63%) patients. Adverse events included perforation in 1 patient (1%) who required surgical management and mouth swelling/abrasion in 3 patients (3%). Follow-up DBE to re-assess disease activity was performed in 10/49 (20%) patients with definitive diagnosis of CD, average time between procedures 4.5 years (range 0.7-11.6). One patient with CD was diagnosed with lymphoma 2.4 years after initial DBE. Changes in management were recommended in 6 patients: de-escalation of therapy (3, two underwent surgery), start thiopurine and/or biologic (2) and switch biologics (1). No complications were seen at follow-up DBE. CONCLUSION: DBE is a useful technique to confirm a diagnosis in patients who have suspected CD and can help establish a diagnosis of several diseases that may mimic CD on CT scan or CE. Additionally, DBE in patients with established diagnosis of small bowel CD is an effective tool to assess disease activity and guide therapy. Serious complications are infrequent.
RESUMEN
INTRODUCTION: EUS-PD (EUS guided pancreatic duct drainage) is classified into two types: EUS-guided rendezvous techniques and EUS-guided PD stenting. Prior studies showed significant variation in terms of technical success, clinical success and adverse events. METHODS: Three independent reviewers performed a comprehensive review of all original articles published from inception to June 2020, describing pancreatic duct drainage utilizing EUS. Primary outcomes were technical success, clinical success of EUS-PDD and safety of EUS-PD in terms of adverse events. All meta-analysis and meta-regression tests were 2-tailed. Finally, probability of publication bias was assessed using funnel plots and with Egger's test. RESULTS: A total of sixteen studies (503 patients) described the use of EUS-PD for pancreatic duct decompression yielded a pooled technical success rate was 81.4% (95% CI 72-88.1, I 2 = 74). Meta-regression revealed that proportion of altered anatomy and method of dilation of tract explain the variance. Overall pooled clinical success rate was 84.6% (95% CI 75.4-90.8, I 2 = 50.18). Meta-regression analysis revealed that the type of pancreatic duct decompression, proportion of altered anatomy and follow up time explained the variance. Overall pooled adverse event rate was 21.3% (95% CI 16.8-26.7, I 2 = 36.6). The most common post procedure adverse event was post procedure pain. Overall pooled adverse event rate of post EUS-PD pancreatitis was 5% (95% CI 3.2-7.8, I 2 = 0). CONCLUSION: The systematic review, meta-analysis and meta-regression provides answer to the questions of the overall technical success, clinical success and the adverse event rate of EUS-PD by summarizing the available literature.

BACKGROUND AND AIMS: EMR and endoscopic submucosal dissection (ESD) are treatment modalities for Barrett's esophagus involving high-grade dysplasia or early cancer. Injectional corticosteroid therapy decreases the risk of procedure-related esophageal stricture (ES) formation. Our aim was to assess the efficacy of topical budesonide on the rate of ES formation after EMR or ESD. METHODS: Patients included prospectively from 3 tertiary endoscopy centers received 3 mg budesonide orally twice a day for 8 weeks after esophageal EMR or ESD of 50% or more of the esophageal circumference between January 1, 2014 and June 30, 2018. These patients were matched (1:3 ratio) retrospectively with a consecutive patient cohort who underwent EMR or ESD of 50% or more of the esophageal circumference without concomitant corticosteroid therapy. The primary endpoint was the presence of ES at the 12-week follow-up. RESULTS: Twenty-five patients (budesonide) were matched with 75 patients (no budesonide). Most underwent EMR for Barrett's esophagus with biopsy-proven high-grade dysplasia or suspected T1a cancer. Although most baseline characteristics did not differ significantly, patients in the budesonide cohort tended to have a higher proportion of circumferential EMR. The proportion of patients with ES was not significantly lower in the budesonide cohort (16% vs 28%). On logistic regression analysis, budesonide remained associated with a lower incidence of ES (P = .023); however, when controlling for baseline characteristics with a propensity score weighted logistic regression model, there was no significant effect on ES formation (P = .176). CONCLUSIONS: Topical budesonide might be associated with a reduction of ES after EMR or ESD; however, further studies are needed to verify our results.

BACKGROUND: High quality bowel preparation prior to colonoscopy can be difficult to achieve in the inpatient setting. Hospitalized patients are at risk for extended hospital stays and low diagnostic yield due to inadequate bowel preparation. The Pure-Vu System is a novel device intended to fit over existing colonoscopes to improve intra-colonoscopy bowel preparation. The objective of the REDUCE study was to conduct the first inpatient study to evaluate optimization of bowel preparation quality following overnight preparation when using the Pure-Vu System during colonoscopy. METHODS: This multicenter, prospective feasibility study enrolled hospitalized subjects undergoing colonoscopy. Subjects recorded the clarity of their last bowel movement using a 5-point scale prior to colonoscopy. After one night of preparation, all enrolled subjects underwent colonoscopy utilizing the Pure-Vu System. The primary endpoint was improvement of colon cleanliness from baseline to post-cleansing with the Pure-Vu System as assessed by the improvement in Boston Bowel Preparation Scale (BBPS). An exploratory analysis was conducted to assess whether the clarity of the last bowel movement could predict inadequate bowel preparation. RESULTS: Ninety-four subjects were included. BBPS analyses showed significant improvements in bowel preparation quality across all evaluable colon segments after cleansing with Pure-Vu, including left colon (1.74 vs 2.89; p < 0.0001), transverse colon (1.74 vs 2.91; p < 0.0001), and the right colon (1.41 vs 2.88; p < 0.0001). Prior to Pure-Vu, adequate cleansing (BBPS scores of ≥ 2) were reported in 60%, 62%, and 47% for the left colon, transverse colon, and right colon segments, respectively. After intra-colonoscopy cleansing with the Pure-Vu System, adequate colon preparation was reported in 100%, 99%, and 97% of the left colon, transverse colon, and right colon segments, respectively. Subjects with lower bowel movement clarity scores were more likely to have inadequate bowel preparation prior to cleansing with Pure-Vu. CONCLUSIONS: In this feasibility study, the Pure-Vu System appears to be effective in significantly improving bowel preparation quality in hospitalized subjects undergoing colonoscopy. Clarity of last bowel movement may be useful indicator in predicting poor bowel preparation. Larger studies powered to evaluate clinical outcomes, hospital costs, and blinded BBPS assessments are required to evaluate the significance of these findings.

BACKGROUND: Lymphocytic esophagitis is a rare esophageal condition. Our knowledge of potential risk factors and treatment outcomes of lymphocytic esophagitis is limited. AIM: To investigate potential risk factors associated with the development of lymphocytic esophagitis and compare clinical characteristics and treatment outcomes of patients diagnosed with lymphocytic esophagitis to patients diagnosed with eosinophilic esophagitis. METHODS: This is a multicenter retrospective study. Lymphocytic esophagitis patients were identified based on pathology results between 1997 and 2019. Control groups consisted of patients with normal esophageal biopsies and patients diagnosed with eosinophilic esophagitis. Thirteen potential risk factors for lymphocytic esophagitis were analyzed using univariate and multivariate models including IBD, achalasia, hyperlipidemia, hypothyroidism, celiac sprue, CVID, H. pylori, thymoma, aspirin, opioids, ACE-I, metformin, and statin use. Comparative statistics were performed. RESULTS: Ninety-four adult patients with lymphocytic esophagitis, 344 with eosinophilic esophagitis, and 5202 control patients with normal esophageal biopsies were analyzed. Age older than 60 [adjusted odd ratio (AOR) 1.03, 95% CI 1.02-1.05, p = 0.001], aspirin use (2.7, 95% CI 1.4-4.9, p = 0.001), statin use (2.2, 95% CI 1.2-4.2, p = 0.01), or a diagnosis of achalasia (2.4, 95% 1.08-5.67, p = 0.03) were associated with lymphocytic esophagitis. Compared to eosinophilic esophagitis, lymphocytic esophagitis patients were more likely to respond to medical treatment (95% CI 2.54-12.8, p = 0.0001). CONCLUSIONS: Our data suggests that lymphocytic esophagitis is more likely to be found in older female patients and is significantly associated with achalasia, statin, and aspirin use. Compared to eosinophilic esophagitis, lymphocytic esophagitis is more likely to respond to treatment with medical therapy.

BACKGROUND: Periprocedural intravenous hydration is suggested to decrease the risk of post-ERCP pancreatitis (PEP). However, quality of evidence supporting this suggestion remains poor. Here we hypothesized that aggressive hydration(AH) could be an effective preventive measure. METHODS: Pubmed, EMBASE, CINAHL, Google Scholar, Clinical Trials. gov, Clinical Key, International Standard Randomized Trial Number registry as well as secondary sources were searched through January 2019 to identify randomized controlled studies comparing AH to standard hydration (SH) for prevention of PEP. Pooled odds ratio (OR) and 95% confidence intervals (CIs) were calculated using the random-effects model. RevMan 5.3 was used for analysis. RESULTS: A total of 9 RCTs, with 2094 patients, were included in the meta-analysis. AH reduced incidence of PEP by 56% compared to SH (ORâ¯=â¯0.44, CI:0.28-0.69; pâ¯=â¯0.0004). The incidence of post-ERCP hyperamylasemia also decreased with AH compared to SH (ORâ¯=â¯0.51; pâ¯=â¯0.001). Length of stay decreased by 1 day with AH (Mean Difference (MD): -0.89â¯d; pâ¯=â¯0.00002). There was no significant difference in adverse events related to fluid overload between two groups (OR:1.29; pâ¯=â¯0.81) and post-ERCP abdominal pain (OR:0.35; pâ¯=â¯0.17). Numbers of patient to be treated with AH to prevent one episode of PEP was 17. Final results of the meta-analysis were not affected by alternative effect measures or statistical models of heterogeneity. CONCLUSION: Aggressive hydration is associated with a significantly lower incidence of PEP and it appears to be an effective and safe strategy for the prevention of Post ERCP pancreatitis.

BACKGROUND AND AIMS: Incision of the cricopharyngeal (CP) muscle with flexible endoscopy is an important approach for Zenker diverticulum (ZD) repair with symptomatic resolution in approximately 90% of cases, but recurrence has been reported in up to 20%. We report our experience with a new endoscopic myectomy of the CP muscle and compare the outcome with conventional myotomy of ZD. METHODS: Our retrospective study included all patients with ZD who underwent endoscopic repair between August 1, 2014 and July 31, 2017. Conventional CP myotomy was defined as a vertical cut through the CP muscle. CP myectomy was defined as parallel excisions followed by snare resection at the CP resection base. Measurement of ZD size was based on barium esophagram and endoscopic estimation. Outcomes included ZD recurrence, improvement of dysphagia, and procedure adverse events. RESULTS: Sixty-four patients underwent endoscopic repair for ZD, 44 with CP myotomy and 20 with CP myectomy. Mean (standard deviation) size of ZD was 3.3 cm (1.0) and 3.8 cm (1.2) in the myotomy and myectomy cohorts, respectively (P = .11), and median procedure time was 50 and 56 minutes, respectively (P = .73). In the CP myotomy cohort, 10 patients (22.7%) had recurrence of ZD at a median of 19.1 months, whereas no recurrence was documented in the CP myectomy cohort (P = .02). This trend was also shown in multivariate analysis but was not statistically significant (P = .07). There was no statistical difference in improvement of dysphagia and adverse events. CONCLUSIONS: CP myectomy is a new endoscopic technique for ZD repair. In our experience, it was safe and well tolerated, with a high initial success rate and less ZD recurrence when compared with myotomy.

BACKGROUND: Proximal esophageal stents are poorly tolerated and have a high risk of complications. We report our experience using fully covered, biliary, self-expandable metal stents (B-SEMS) and narrow-diameter, esophageal, self-expandable metal stents (NDE-SEMS) for this group of patients. METHODS: 24 patients underwent placement of B-SEMS or NDE-SEMS for proximal esophageal lesions between 1 January 2011 and 31 July 2016. The outcomes included improvement of dysphagia, healing of fistulas, and adverse events. RESULTS: 10 patients received B-SEMS and 14 had NDE-SEMS.âMedian follow-up time was 11.5 months (range 0.5â-â62 months). In both cohorts, stents were left in place for a mean of 6 weeks. The dysphagia score decreased in 7 (70â%) and 10 (71.4â%) patients, and fistulas resolved in 3/5 (60.0â%) and 5/8 (62.5â%) patients with B-SEMS and NDE-SEMS, respectively. Stent migration occurred in three patients (30.0â%) with B-SEMS and five patients (35.7â%) with NDE-SEMS. CONCLUSIONS: Both stents were well tolerated and resulted in overall improvement of dysphagia in 70.8â% of patients. B-SEMS appeared to be more favorable for cervical esophageal lesions with narrower diameters, while NDE-SEMS may be better for more distal lesions.

OBJECTIVES: To assess national trends of AP (acute pancreatitis) admissions, outcomes, prevalence of AKI (acute kidney injury) in AP, and impact of AKI on inpatient mortality. METHODS: We queried the Nationwide Inpatient Sample database from 2003 to 2012 to identify AP admissions using ICD-9-CM codes. After excluding patients with missing information on age, gender, and inpatient mortality, we used ICD-9-CM codes to identify complications of AP, specifically AKI. We examined trends with survey-weighted multivariable regressions and analyzed predictors of AKI and inpatient mortality by multivariate logistic regression. Additionally, both AKI and non-AKI groups were propensity-matched and regressed against mortality. RESULTS: A total of 3,466,493 patients (1.13% of all discharges) were hospitalized with AP, of which 7.9% had AKI. AP admissions increased (1.02%â1.26%) with rise in concomitant AKI cases (4.1%â11.7%) from year 2003-2012. Mortality rate decreased (1.8%â1.1%) in the AP patients with a substantial decline noted in AKI subgroup (17.4%â6.4%) during study period. Length of stay (LOS) and cost of hospitalization decreased (6.1â5.2 days and $13,654 to $10,895, respectively) in AKI subgroup. Complications such as AKI (OR: 6.08, pâ¯<â¯0.001), septic shock (OR: 46.52, pâ¯<â¯0.001), and acute respiratory failure (OR: 22.72, pâ¯<â¯0.001) were associated with higher mortality. AKI, after propensity matching, was linked to 3-fold increased mortality (propensity-matched OR: 3.20, Pâ¯<â¯0.001). CONCLUSION: Mortality, LOS, and cost of hospitalization in AP has decreased during the study period, although hospitalization and AKI prevalence has increased. AKI is independently associated with higher mortality.

BACKGROUND: Sporadic nonampullary duodenal neoplasms (SNADN) can have malignant potential for which endoscopic and surgical resections are offered. We report combined gastroenterologic and surgical experience for treatment of SNADN, including endoscopic mucosal resection (EMR) and pancreas-preserving partial duodenectomy (PPPD). METHODS: We retrospectively reviewed 121 consecutive patients, who underwent 30 PPPDs and 91 EMRs for mucosal and submucosal SNADN. Decision to undergo EMR or surgical resection was based on expert endoscopist and surgeon discretion including multidisciplinary tumor board review. Main outcomes were recurrence rate of neoplasia and adverse events requiring hospital admission or prolonged care. EMRs were performed with submucosal lifting followed by snare resection. PPPD included total duodenectomy, supra-ampullary PPPD for neoplasms proximal to the ampulla, and infra-ampullary PPPD for lesions distal to the ampulla. Follow-up data were available for 65% of EMR and 73% of surgical patients. RESULTS: Surgically resected neoplasia was larger with more advanced neoplasia and submucosal lesions. En bloc resection was achieved in all surgical resections and in 53% of EMRs. Post-EMR, mucosal and submucosal neoplasia recurred in 32 and 0%, respectively, including five neoplasms (26%) after an initial negative esophagogastroduodenoscopy. All recurrences were treated endoscopically. Complications occurred in 14 endoscopically and eight surgically treated patients, none requiring surgical intervention. CONCLUSIONS: Post-EMR patients had higher recurrence of mucosal neoplasia, whereas submucosal neoplasms, mainly carcinoid, did not recur. Polyp size and positive resection margin were not associated with neoplasia recurrence. Patients with SNADN could benefit from a multidisciplinary approach to stratify the optimal treatment based on local expertise.
