    Impact of Cap-assisted Colonoscopy on Detection of Proximal Colon Adenomas: Systematic Review and Meta-analysis
    Proximal colon adenomas can be missed during routine colonoscopy. Use of a cap or hood on tip of the colonoscope has shown to improve overall adenoma detection with variable rates. However, it has not been systematically evaluated for detection of proximal colon or right-sided adenomas where the cap may have maximum impact on adenoma detection rate (ADR). Our aim was to perform a systematic review and meta-analysis to evaluate the impact of cap colonoscopy (CC) on right-sided adenoma detection rates (r-ADR) compared with standard colonoscopy (SC).

    Computer-aided detection of early Barrett’s neoplasia using volumetric laser endomicroscopy
    Volumetric laser endomicroscopy (VLE) is an advanced imaging system that provides a near-microscopic resolution scan of the esophageal wall layers up to 3 mm deep. VLE has the potential to improve detection of early neoplasia in Barrett’s esophagus (BE). However, interpretation of VLE images is complex due to the large amount of data that needs to be interpreted in real-time. The aim of this study was to investigate the feasibility of a computer algorithm to identify early BE neoplasia on ex vivo VLE images.

    EUS-guided portal vein interventions
    The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methods are used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported adverse events of a given technology. Both are supplemented by accessing the “related articles” feature of PubMed and by scrutinizing pertinent references cited by the identified studies.

    Thermo-sensitive isopentane aerification for mucosal lift during endoscopic resection in animal models (with video)
    Mucosal lift is critical for successful endoscopic treatment. Normal saline solution (NS) is widely used as the submucosal filler, but its short persistency restricts clinical endoscopic submucosal dissection (ESD) procedure. In this study, thermo-sensitive isopentane was introduced for submucosal injection. With a 27.8°C boiling point, liquid isopentane could be easily applied, whereas gasification inflation could provide great support for submucosal lifting at body temperature. The feasibility and efficiency of isopentane were evaluated in this study.

    Etomidate Versus Propofol Sedation For Complex Upper Endoscopic Procedures: A Prospective Double-Blinded Randomized Controlled Trial
    Although a growing body of evidence demonstrates that propofol-induced deep sedation can be effective and performed safely, cardiopulmonary adverse events have been frequently observed. Etomidate is a new emerging drug that provides hemodynamic and respiratory stability, even in high-risk patient groups. The objective of this study was to compare safety and efficacy profiles of etomidate and propofol for endoscopic sedation.

    Asia–Pacific Consensus Guidelines for Endoscopic Management of Benign Biliary Strictures
    Benign biliary strictures (BBSs) are commonly caused by surgical injury, chronic pancreatitis, and inflammatory cholangiopathies. Although advanced imaging tests and tissue acquisition methods have been developed for evaluation of indeterminate biliary strictures, differentiation of BBSs from biliary malignancies remains a challenge to clinicians. The majority of BBSs have good response to nonsurgical treatment and surgical intervention mainly serves as a rescue when nonsurgical approaches fail.

    Clinical outcomes after endoscopic submucosal dissection for colorectal neoplasia: a systematic review and meta-analysis
    Endoscopic submucosal dissection (ESD) is an endoscopic resection technique for lesions suspicious of superficial malignancy. It is performed using an ESD knife on its own (standard technique) or by the sequential use of a knife and a snare (hybrid technique). The experience with these techniques is different in Asian and non-Asian countries. We performed a systematic review and meta-analysis of available evidences on colorectal ESD.

    Safety and Efficacy of Cap-Assisted Endoscopic Mucosal Resection for Sporadic Nonampullary Duodenal Adenomas
    Eradication of sporadic non-ampullary duodenal adenomas (SNADAs) is essential due to their high rate of malignant transformation. Endoscopic mucosal resection (EMR) techniques are the alternative to the traditional surgical treatments of SNADAs. There are very limited data on the safety and efficacy of cap-assisted EMR (C-EMR) in the treatment of SNADA.

    The diagnostic performance of JNET classification for differentiation among noninvasive, superficially invasive, and deeply invasive colorectal neoplasia
    The Japan NBI Expert Team (JNET) classification is the first universal narrow-band imaging (NBI) magnifying endoscopic classification of colorectal tumors. Considering each type in this classification, the diagnostic ability of Type 2B is the weakest. Generally, clinical behavior is thought to be different in each gross type of colorectal tumor. We evaluated the differences in the diagnostic performance of JNET classification for each gross type (polypoid and superficial) and examined whether the diagnostic performance of Type 2B could improve by subtyping.

    Unexpected finding after gastroduodenal artery embolization
    An 87-year-old woman with melena and anemia was admitted to the hospital and underwent urgent GI endoscopy. During the procedure, a large clot adhering to the posterior wall of the duodenal bulb was identified. Its removal with a retrieval net revealed an underlying visible vessel with active oozing (A). After an ineffective attempt to obtain endoscopic hemostasis with epinephrine injection, argon plasma coagulation, and clips, interventional radiology was performed. Selective arteriography of the celiac trunk revealed no extravasation, so blind embolization of the gastroduodenal artery with 3 platinum coils (SPIRALES.018″, coil ∅ 3 mm, coil length 5 cm; Balt Extrusion, Montmorency, France) was carried out (B, continous arrow: coil; dashed arrow: clip).

    Technical aspects of endoscopic sleeve gastroplasty
    Of the currently available endoscopic bariatric options in the United States, endoscopic sleeve gastroplasty (ESG) appears to be the most effective and durable. However, it is highly operator dependent. In ESG, the volume of the stomach is reduced by approximately 70% through the creation of a small-diameter sleeve along the lesser curvature of the stomach by use of an endoscopic suturing device (OverStitch, Apollo Endosurgery, Austin, Tex). We present a case that demonstrates important technical aspects of the ESG procedure.

    Endoscopic recovery of multiple migrated plastic stents during EUS-guided transmural drainage of pancreatic fluid collections
    EUS-guided transmural drainage of pancreatic fluid collections is widely used, and multiple stents and nasocystic drainage are necessary for effective drainage in cases of pancreatic necrosis. Stent migration into the necrotic cyst is a possible adverse event of such procedures. Retrieval of migrated stents by the direct insertion of an endoscope into the cyst can be considered, but there is a high incidence of severe adverse events. We describe a case of multiple plastic stent migration into a pancreatic necrotic cyst, in which the stents were successfully recovered by use of a minimally invasive endoscopic technique.

    Medical, endoscopic, and surgical management of ileal pouch strictures (with video)
    The construction of ileal pouch-anal anastomosis (IPAA) is the procedure of choice for patients with ulcerative colitis or familial adenomatous polyposis, who require colectomy. Furthermore, IPAA has the advantage of preserving the natural route of defecation unlike the Brooke’s ileostomy or continent ileostomies. On the other hand, the natural history of patients with the ileal pouch can be complicated by various surgical-procedure–associated mechanical adverse events as well as inflammatory and functional disorders.

    Prevalence of hypokalemia before and after bowel preparation for colonoscopy in high-risk patients
    Bowel preparation for colonoscopy should not cause significant shifts in systemic electrolyte concentrations. We recently encountered 2 cases of severe postcolonoscopy hypokalemia with fatal consequences, prompting us to conduct a study to explore the magnitude of and risk factors for hypokalemia associated with bowel preparation. We paid specific attention to higher-risk subgroups, in particular, diuretic users, hospitalized patients, and patients estimated at to be high risk by the gastroenterologist.

    A preliminary study of single operator cholangioscopy for diagnosing pancreatic cystic lesions
    Advances in imaging technology have improved the annual detection rate of pancreatic cystic lesions, but the preoperative diagnosis of pancreatic cystic lesions remains unclear. Thus, the usefulness of single operator cholangioscopy (SOC) as a diagnostic imaging tool for pancreatic cystic lesions is worth investigating. We performed an intracystic visual examination of pancreatic cystic lesions using SOC to determine the diagnostic value of SOC for pancreatic cystic lesions.

    Urgent colonoscopy in patients with lower GI bleeding: a systematic review and meta-analysis
    Lower GI bleeding (LGIB) is a common cause of morbidity and mortality. Colonoscopy is indicated in all hospitalized patients with LGIB, yet the time frame for performing colonoscopy remains unclear. Prior studies of outcomes in urgent versus elective colonoscopy have yielded conflicting results and were often underpowered. Our study objective was to compare several outcomes between urgent and elective colonoscopy in patients hospitalized for LGIB.

    Indomethacin and diclofenac in the prevention of post-ERCP pancreatitis: a systematic review and meta-analysis of prospective controlled trials
    Diclofenac and indomethacin are the most studied drugs for preventing post-ERCP pancreatitis (PEP). However, there are no prospective, randomized multicenter trials with a sufficient number of patients for correct evaluation of their efficacy. Our aim was to evaluate all prospective trials published in full text that studied the efficacy of diclofenac or indomethacin and were controlled with placebo or non-treatment for the prevention of PEP in adult patients undergoing ERCP.

    Feasibility of laser marking in Barrett’s esophagus with volumetric laser endomicroscopy: first-in-man pilot study
    Volumetric laser endomicroscopy (VLE) provides a circumferential scan of the esophageal wall layers and has potential to improve detection of neoplasia in Barrett’s esophagus (BE). The novel VLE laser marking system enables direct in vivo marking of suspicious areas as identified on VLE. These laser marked areas can subsequently be targeted for biopsies. The aim was to evaluate the visibility and positional accuracy of laser marks (LMs) in different esophageal tissue types on white light endoscopy (WLE) and VLE.

    Complex early Barrett’s neoplasia at 3 Western centers: European Barrett’s Endoscopic Submucosal Dissection Trial (E-BEST)
    Endoscopic submucosal dissection (ESD) is an effective technique to resect early Barrett’s neoplasia and has advantages over conventional EMR in that it enables en-bloc resection and accurate histopathologic analysis of cancer resection margins. However, its long learning curve and higher adverse event rate have tempered its uptake in the West. We aimed to analyze the safety and efficacy of ESD when used to resect complex Barrett’s neoplasia. The primary endpoint was the en-bloc and R0 resection rate.

    Exploring endoscopic therapy for the treatment of Crohn’s disease–related fistula and abscess
    Fistula and abscess represent penetrating disease phenotypes of Crohn’s disease (CD) and can develop in patients with or without prior history of CD-related surgery. While CD fistula and abscess have been traditionally treated with medical and surgical therapy, the role of endoscopic therapy in this particular phenotype of CD is expanding recently, thanks to advanced endoscopic techniques and a better understanding of pathogenesis and natural history of the disease and principle of treatment. The success of endoscopic treatment for inflammatory bowel disease depends on comprehension and appreciation of principles, then techniques, followed by instrument and device.

    Oral administration of conditioned medium obtained from mesenchymal stem cell culture prevents subsequent stricture formation after esophageal submucosal dissection in pigs
    Endoscopic submucosal dissection (ESD) for esophageal cancer often causes postoperative stricture when more than three fourths of the circumference of the esophagus is dissected. Mesenchymal stem cells are a valuable cell source in regenerative medicine, and conditioned medium (CM) obtained from mesenchymal stem cells reportedly inhibits inflammation. In this study we evaluated whether CM could prevent esophageal stricture after ESD.

    Providing data for serrated polyp detection rate benchmarks: an analysis of the New Hampshire Colonoscopy Registry
    Similar to achieving adenoma detection rate (ADR) benchmarks to prevent colorectal cancer (CRC), achieving adequate serrated polyp detection rates (SDRs) may be essential to the prevention of CRC associated with the serrated pathway. Previous studies have been based on data from high-volume endoscopists at single academic centers. Based on a hypothesis that ADR is correlated with SDR, we stratified a large, diverse group of endoscopists (n = 77 practicing at 28 centers) into high performers and low performers, based on ADR, to provide data for corresponding target SDR benchmarks.

    Detectability of colorectal neoplastic lesions using a novel endoscopic system with blue laser imaging: a multicenter randomized controlled trial
    Most studies have not reported an improvement in the detection of adenomas with the use of image-enhanced colonoscopy methods, possibly because of the darkness of the images. To overcome this limitation, a new-generation endoscopic system has been developed. This system has 2 blue-laser imaging (BLI) observation modes. The BLI observation was set to BLI-bright mode to detect lesions. We aimed to evaluate the efficacy of BLI in detecting lesions.

    Molecular imaging of mucosal α4β7 integrin expression with the fluorescent anti-adhesion antibody vedolizumab in Crohn’s disease
    Molecular imaging is based on the use of fluorescent probes with specificity toward defined molecular targets and their visualization by endoscopic devices such as confocal laser endomicroscopy (CLE). Herein, we describe successful molecular imaging of the α4β7 integrin through CLE in Crohn’s disease (CD). Five patients with CD refractory to anti-tumor necrosis factor (TNF) therapy and with active mucosal inflammation, as shown by high-definition endoscopy, were studied (A). Before induction therapy with the anti-α4β7 antibody vedolizumab (VDZ), molecular imaging of α4β7 with fluorescein isothiocyanate (FITC)–labeled VDZ allowed specific identification of α4β7 expressing mucosal cells with clear discrimination against FITC-IgG1 isotype control in 2 patients with CD responding to subsequent VDZ therapy (B).

    Comparison of FNA and fine-needle biopsy for EUS-guided sampling of suspected GI stromal tumors
    Subepithelial lesions are found in about 1% of all EGD procedures, and GI stromal tumors are a type of subepithelial lesion commonly encountered. Although the majority of subepithelial lesions are benign, GI stromal tumors have malignant potential, making a definitive diagnosis important. Currently, the criterion standard for the diagnosis of GI stromal tumors is EUS-directed FNA (EUS-FNA). The definitive diagnosis of GI stromal tumors relies on immunohistochemical staining, which depends on enough tissue being submitted to the pathologist.

    How robust is our peer-review system? A review of emerging models
    Peer review is an enduring institution for ensuring quality and integrity of research. Every year dedicated editors and reviewers carefully sift through thousands of manuscripts and videos from behind the scenes. This scholarly cycle of sorting, correcting, purging, and publishing is almost routine and was taken for granted, until something unthinkable happened that alarmed the scientific world. A submitting author systematically recommended names of potential reviewers to scientific journals and then hacked into their electronic editorial systems to provide fictitious e-mail addresses, enabling him to create favorable reviews that led to his manuscripts being accepted and published.

    Comparison of carbon dioxide and air insufflation during consecutive EGD and colonoscopy in moderate-sedation patients: a prospective, double-blind, randomized controlled trial
    Endoscopy is performed with air insufflation and is usually associated with abdominal pain. It is well recognized that carbon dioxide (CO2) is absorbed more quickly into the body than air; however, to date, few studies have investigated the use of CO2 insufflation during consecutive EGD and colonoscopy (CEC). Thus, this study evaluated the efficacy of CO2 insufflation compared with air insufflation in CEC.

    Role of EUS in patients with suspected Barrett’s esophagus with high-grade dysplasia or early esophageal adenocarcinoma: impact on endoscopic therapy
    Endoscopic therapy is the standard treatment for high-grade dysplasia and some cases of T1a esophageal adenocarcinoma (EAC), but it is not appropriate for deeply invasive disease. Data on the value of EUS for patient selection for endoscopic or surgical resection are conflicting. We investigated the outcome of esophageal EUS for the staging and treatment selection of patients with treatment-naive, premalignant Barrett’s esophagus (BE) and suspected superficial EAC.

    Cumbersome removal of a lumen-apposing metal stent in a case of refractory pancreatic pseudocyst
    A 32-year-old man with previous severe pancreatitis received a diagnosis of pancreatic pseudocyst and was treated by 3 different methods of drainage. There was no communication between the pseudocyst and the pancreatic duct. The pseudocyst was first discovered 3 years previously (A) and was treated by percutaneous drainage. One year later, in August 2014, the patient presented with abdominal pain and distension again, and EUS showed a huge pseudocyst (15 cm × 15 cm) in the body of the pancreas. We placed a biliary metal stent under the guidance of EUS and removed it 4 months later, but the pseudocyst recurred afterward.

    Predictive overbooking and active recruitment increases uptake of endoscopy appointments among African American patients
    Use of GI endoscopy is historically lower in nonwhite ethnic and racial groups compared with whites. These disparities are multifactorial but likely contribute to differences in GI clinical outcomes. We sought to improve endoscopy uptake overall and in minorities by predictive overbooking and active recruitment in a hospital-based GI clinic.

    Sleeve gastrectomy leak: endoscopic management through a customized long bariatric stent
    A 28-year-old woman, body mass index 35 kg/m2, underwent laparoscopic sleeve gastrectomy, without drain placement. Twelve days later, she experienced abdominal pain with radiation to her left shoulder, fever, and leukocytosis. The patient was admitted with a clinical diagnosis of gastric leak. Endoscopy showed a leak orifice below the gastroesophageal junction (GEJ), allowing passage to a perigastric cavity, with a small amount of purulent fluid and debris (Figs. 1A and B). This cavity was endoscopically washed with saline solution until the return of fluid was clear.

    The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee’s recently published Status Evaluation Report entitled “Automated endoscope reprocessors” (Gastrointest Endosc 2016;84:885-92) listed the automated endoscope reprocessors (AERs) that have been U.S. Food and Drug Administration (FDA)-cleared for use in Table 2.1 This table inadvertently failed to include the Custom Ultrasonics (Ivyland, PA) System 83 Plus, which is FDA-cleared for reprocessing flexible endoscopes other than duodenoscopes.

    Classifications for optical diagnosis of colorectal lesions: not 2B with JNET
    Optical diagnosis of colorectal lesions with image-enhanced endoscopy is becoming progressively established in Western colonoscopy practice. It is the cornerstone of 2 management strategies for diminutive colorectal polyps proposed by the American Society for Gastrointestinal Endoscopy (ASGE): “resect and discard,” in which diminutive adenomas are identified, resected, and discarded without pathologic confirmation; and “diagnose and leave,” in which hyperplastic polyps identified in the rectosigmoid colon are left without resection.

    Duodenal adenomas in sporadic and familial adenomatous polyposis patients: Birds of a feather?
    Familial adenomatous polyposis (FAP) is an autosomal dominantly inherited condition caused by mutation in the APC gene and is characterized by hundreds to thousands of adenomatous colorectal polyps.1 Affected persons have a lifetime risk for colorectal cancer of up to 100% without colectomy. Colonoscopy is recommended as early as age 10 years with yearly surveillance procedures. Most patients undergo colectomy because of the significant polyp burden.

    Third-space endoscopy: stretching the limits
    Gastrointestinal endoscopy was invented and traditionally practiced over the past 60-odd years for visualization of the gut lumen. Since its invention, the fear most dreaded by GI endoscopists has been inadvertent injury of the gut wall, leading to a full-thickness perforation. If it occurs, this adverse event has given sleepless nights to even the most experienced endoscopists. GI endoscopy has, however, metamorphosed rapidly over the past few decades from a purely diagnostic procedure into a powerful therapeutic tool.

    Addressing disparities in the African-American community: one size does not fit all!
    Over the past several years, attention has finally been paid to issues of health inequities in the United States. A refocusing, in light of current disparities seen in the health of minorities, has been particularly germane regarding GI malignancies in the African-American community. Reductions in colorectal cancer (CRC) have been strikingly much slower among African Americans, who continue to have the highest rate of mortality and lowest survival when compared with all other racial groups.1 Much of the dramatic lowering of CRC incidence and mortality in the general population can be attributed to successful CRC screening, particularly colonoscopy.

    Can we preserve sphincter of Oddi function by avoiding sphincterotomy? Do we want to?
    Durable endoscopic treatment of choledocholithiasis requires the extraction of gallstones through the sphincter of Oddi muscle complex. With or without stone fragmentation, this maneuver requires adequate expansion of the ampullary and biliary components of the sphincter of Oddi through sphincterotomy, balloon orifice dilation, or both. In the approach to a patient with choledocholithiasis, the prevailing concern is to remove the stones completely and with as little risk and need for reintervention as possible.

    Endoscopic papillectomy for adenoma: To inject or not to inject? That is no longer the question
    In our world of procedures, many endoscopists, including myself, hold beliefs and opinions, often based on personal experience, that are not necessarily substantiated by evidence or even a logical approach to a particular disease state or endoscopic challenge. This is not surprising because, despite our scientific best intentions, there can never be observational or randomized studies on every subtle variation in endoscopic technique or every accessory. Hence the teachings of staunch advocates for a particular type of knife for endoscopic submucosal dissection, a particular modality for hemostasis, a particular method of cannulation at ERCP, a particular guidewire for access or stent insertion, use of particular stents in certain situations, and so on.

    The hunger games: lessons from the past to shape the future
    It is now evident that bariatric and metabolic surgical interventions offer more efficacious and durable weight loss than nonsurgical approaches.1 This efficacy is mediated by multiple anatomic manipulations to the stomach and small intestines resulting in physiologic alterations in gut neuroendocrine signaling, GI motility, autonomic nervous system signaling, bile acid production and absorption, and alterations in gut microbiota leading to a decrease in body weight and adiposity with improvement in the metabolic and mechanical consequences of obesity.

    Early adverse events of per-oral endoscopic myotomy: the risk factors
    We have read with great interest the article by Werner et al,1 in which they suggested a classification of adverse events (AEs) for per-oral endoscopic myotomy (POEM) and found that the incidence is low, especially for severe AEs. They also noticed that rates of AEs were not significantly different among age, sex distribution, pretreatment, myotomy length, and other factors, using univariate analysis. However, univariate analysis alone is not powerful enough to explore the risk factors, and it would be better if multivariate analysis or Cox proportional hazard model was used for risk factors of AEs, especially severe AEs, so that endoscopists who are performing or going to perform POEM could pay attention to these factors and try to reduce or prevent these AEs.

    Benign esophageal strictures: rule of 3 in esophageal dilation does not need to be a rule
    We read with great interest the article in Gastrointestinal Endoscopy by Grooteman et al1 on the nonadherence to the rule of 3 not increasing the risk of adverse events in esophageal dilation. The rule of 3, theoretically applicable to bougienage alone, was intended to preclude overaggressive dilation. Major adverse events occurred in 1% of 2216 dilation sessions (bougie or balloon dilations), with 0.5% perforations. Nonadherence to the rule of 3 occurred in 13% of bougie dilations. However, dilation to more than 3 mm in 1 session was not associated with more adverse events.

    Esophageal self-dilations as a treatment for refractory benign esophageal strictures
    It was with great interest that we read the study by Repici et al1 on refractory benign esophageal strictures (RBES) and the accompanying editorial by Dr Siersema.2 This study should be commended for reporting a long-term follow-up in RBES treated with endoscopic dilation, self-expandable metallic stents, biodegradable stents, and steroid injections. The study was also comprehensive in analyzing the treatment effect on strictures that differ in location, length, and cause. Ultimately, the study found only a 31.4% rate of clinical resolution for patients with RBES; patients treated with endoprostheses had even a lower rate of successful outcome.

    Filling the gap: safety of per-oral endoscopic myotomy attested by evidence
    Seven years after its initial application, per-oral endoscopic myotomy (POEM) can hardly still be described as an experimental procedure for the treatment of achalasia. As of July 31, 2016, a PubMed search on POEM returned 275 publications, a rather extraordinary figure for a procedure developed for a rare disease.

    Zipper clip closure of colonoscopic perforations
    This author read with great interest the article by Kantsevoy et al1 on endoscopic management of colonic perforations: closure by clips versus suturing. In this retrospective study, primary closure of a colonic perforation was performed with endoscopic through-the-scope (TTS) clips in 5 patients and sutured with an endoscopic suturing device in 16 patients. All 5 patients after EMR with cecal perforation (mean size, 3.4 ± 2.1 mm; range 3-5 mm) after clip closure had worsening of abdominal pain and required laparoscopy (4 patients) or rescue colonoscopy with endoscopic suturing closure (1 patient).
