RESUMEN
High-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders, yet it can be poorly tolerated and technically challenging. Epiphrenic diverticula (ED) are located in the distal esophagus and are associated with underlying motility disorders. ED patients (2008-2022) were retrospectively compared to achalasia patients (2008-2022) and all other patients (2021-2022) who underwent HRM at a single center. Complete success was defined as at least 7 interpretable swallows including measurements throughout the esophagus into the stomach. HRM studies involving children, previously treated achalasia, and sedation or endoscopic-assistance were excluded. 20 ED patients (mean age 66; 60% female) were compared to 76 achalasia patients and 199 controls. HRM was completely successful in 70.0% of ED patients, 85.5% of achalasia (p = 0.106 vs ED), and 91.0% of controls (p = 0.004 vs ED). Most failures in the ED and achalasia groups were due to inability to traverse the esophagogastric junction (EGJ), while patient intolerance was the main reason in controls. Half of the ED group had motility disorders (25% achalasia, 15% hypercontractile esophagus, 10% absent contractility). Large diverticulum size was inversely associated with technical success compared to small diverticulum size (40% vs 100%, p = 0.013), while the presence of a motility disorder did not significantly affect success (60% vs 88.9%, p = 0.303). In conclusion, ED is a predictor of unsuccessful HRM. This appears to be mainly related to an inability to traverse the EGJ due to the size of the diverticulum. Consideration should be given to alternative means of evaluating motility, such as endoscopy-assisted HRM, given the high likelihood of failure with traditional HRM.

Esophageal high-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders. As this is performed without sedation, it may be poorly tolerated by patients. Additionally, advancing the catheter tip until the stomach may also be difficult, especially if there is a disease affecting the esophagus or esophagogastric junction which may lead to coiling of the catheter. Currently, there are no guidelines as to who can perform HRM. An expert opinion has recommended minimum numbers of cases for the operator to perform in order to obtain and maintain competency. Several studies have reported on the rates of flawed HRM studies with approximately 20% being imperfect, including about 3% with critical flaws. The presence of a large hiatal hernia and achalasia have been identified as predictors of technical failure. Studies with minor flaws are usually still interpretable and clinically useful. Reports have also described several techniques for sedation-assisted placement of the HRM catheter, and this appears to be a promising alternative in cases of failed HRM, especially as sedation does not appear to significantly affect HRM measurements. An algorithm on how to proceed after a technically imperfect HRM study is proposed. Further research in this field is warranted including confirmation of the recommended competency numbers, assessing for quality measures in performing HRM such as technical success rate, identifying additional predictors of technical failure, standardization of the terminology, and qualifying the benefit of sedation-assisted HRM.

BACKGROUND: Ethnic differences in achalasia presentations have scarcely been described. The association between achalasia and immunologic HLA haplotypes suggests that there may be a genetic predisposition. We aimed to evaluate differences in demographic, clinical, endoscopic, and manometric findings between two distinct ethnic groups with achalasia-Israeli Arabs (IA) and Israeli Jews (IJ). METHODS: A retrospective study was performed at two medical centers. High-resolution manometry (HRM) reports were reviewed for newly-diagnosed achalasia patients. Demographic data, clinical presentations, endoscopy reports, and HRM metrics including the integrated relaxation pressure (IRP) were all reviewed. RESULTS: Overall, 94 achalasia patients were included (53.2% male; mean age 54.5 ± 18.0). 43 patients were IA (45.7%). Body mass index (BMI) was similar in both groups. Compared to IJ, the IA patients had more esophageal dysphagia (100% vs. 88.2%; P = 0.022), chest pain (46.5% vs. 25.5%; P = 0.033), and a tortuous esophagus on endoscopy (23.3% vs. 3.9%; p = 0.005). IA patients were also diagnosed at a younger age than IJ patients (50.9 ± 17.5 vs. 57.5 ± 18.0; p = 0.039). Furthermore, IRP values were higher among IA patients than IJ patients (32.2 ± 13.8 vs. 23.3 ± 8.4; p < 0.001). A regression model analysis found that ethnicity significantly predicted IRP (ß = - 10, p < .001). CONCLUSION: Ethnicity appears to affect achalasia clinical presentation and HRM findings. IA achalasia patients are diagnosed at a younger age, present with more severe esophageal symptoms, and have a higher IRP compared to IJ patients. Additional studies of diverse, multiethnic populations, especially with genetic evaluations, are required to further assess the role of ethnicity in achalasia.

OBJECTIVES: Esophageal motility disorders (EMDs) are a known risk factor for esophageal candidiasis (EC), but this relation has not been described particularly well. We sought to evaluate the predictors of underlying EMDs in patients presenting with EC. METHODS: Cases of EC at a single medical center between 2010 and 2021 were identified retrospectively based on the International Classification of Diseases, Ninth Revision code. Demographic, clinical, endoscopic, and manometric data were reviewed. The diagnosis of EC was based on typical endoscopic appearance. RESULTS: In total, 130 EC patients were identified (mean age 69.5 ± 14.6; 66.2% male). Of these, 12 (9.2%) had an underlying EMD (11 cases of achalasia; 1 case of esophagogastric junction outflow obstruction). Five (41.7%) of these patients had previously been diagnosed as having an EMD, whereas 7 were newly diagnosed only after their presentation with EC. No significant differences were noted between those with or without EMDs in terms of demographics, medical comorbidities, or medication use. Patients with an EMD, however, were more likely to complain of dysphagia (91.7% vs 30.5%, P < 0.001), and on endoscopy, they were more likely to have residual food in the esophagus, residual fluid in the esophagus, a dilated esophagus, and resistance to traversing the esophagogastric junction (all P < 0.001). Sixty-one (46.9%) patients with EC died during follow-up (mean 58 months). CONCLUSIONS: EMDs are present in approximately 10% of patients presenting with EC, with half being diagnosed only after presenting with EC. Similar to non-EC patients, patients with EC with dysphagia and the typical endoscopic findings of achalasia are more likely to have an EMD and warrant prompt manometric evaluation.

Past studies have reported differences between pediatric and adult celiac disease patients. We aimed to compare factors associated with adherence to a gluten-free diet between these groups. An anonymous online questionnaire was sent via the Israeli Celiac Association and social networks to celiac patients. The Biagi questionnaire was used to assess dietary adherence. A total of 445 subjects participated. Mean age was 25.7 ± 17.5 years and 71.9% were female. Subjects were divided into six groups according to age at diagnosis: younger than 6 years (134 patients, 30.7%), 6-12 (79 patients, 18.1%), 12-18 (41 patients, 9.4%), 18-30 (81 patients, 18.5%), 30-45 (79 patients, 18.1%), and 45 years and above (23 patients, 5.3%). There were several significant differences between childhood- and adulthood-diagnosed patients. Pediatric patients were less likely to be noncompliant with a gluten-free diet (3.7% vs. 9.4%, p < .001). They were also more frequently followed by a gastroenterologist ( p < .001), a dietitian ( p < .001), and participated in a celiac support group ( p = .002). In logistic regression analyses, longer duration of disease was associated with poor compliance. In conclusion, pediatric-diagnosed celiac patients are more adherent to a gluten-free diet than those diagnosed in adulthood, with better social support and nutritional follow-up possibly contributing.

Background and Objectives: The ever-expanding entry of biosimilar drugs into the Israeli market requires doctors to decide whether to prescribe these medications. We aimed to assess the prevalence of biosimilar use and Israeli gastroenterologists' knowledge, experience, and perception of biosimilar treatment. Materials and Methods: A cross-sectional survey was conducted among Israeli Gastroenterology Association (IGA) members between March and May 2022 using a structured 20-item questionnaire. Results: The questionnaire was completed by 108 gastroenterologists. Sixty-two percent prescribed biosimilars to their patients in the past year. Most of the patients (81%) were biologically naïve and only 19% were switched to a biosimilar. Most gastroenterologists (75%) answered that the effectiveness is the same. The rates of resistance to switching were 19%, 36%, and 70% for patients in remission for over two years, pregnant women, and difficulty reaching remission, respectively. In cases seeing a lack of response after switching, most physicians chose to change the mechanism of action, with only a small percentage returning to the brand-name drug. Conclusions: Most Israeli gastroenterologists are not concerned about biosimilars' safety and efficacy. Despite this, most physicians will prefer the brand-name drug, especially regarding adalimumab. The populations in which physicians most oppose switching are those who have had difficulty achieving remission and pregnant women.

BACKGROUND: One of the main causes of iron deficiency anemia (IDA) is chronic gastrointestinal blood loss. The use of video capsule endoscopy (VCE) after negative bidirectional endoscopy in patients with IDA is controversial. OBJECTIVES: To evaluate the effect of VCE in the management and long-term outcomes of IDA patients. METHODS: A retrospective case-control study was performed on all patients with IDA undergoing VCE over a 5-year period. We compared those with positive findings on VCE to those with normal findings. All participants previously underwent a negative bidirectional endoscopy. RESULTS: We performed 199 VCE examinations; median follow-up time was 4 years (IQR 2-5). Positive findings were identified in 66 patients (diagnostic yield 33.2%). Double balloon enteroscopy or push enteroscopy was performed in eight patients (18.6%); only one was therapeutic. The main therapy in both groups was iron supplementation. There were no significant differences in iron treatment before and after VCE in each group and between groups. Anemia improved in both groups. There was no difference in the level of hemoglobin change between the groups during each year of follow-up compared to the baseline level prior to VCE. Anemia resolved in 15 patients (35%) in the positive VCE group and in 19 (45%) in the negative VCE group (P = 0.33). CONCLUSIONS: Positive findings on VCE led to subsequent endoscopic interventions only in a small percentage of patients with IDA. Anemia improved and resolved equally whether or not there were VCE findings. The main intervention that appears to help IDA is iron supplementation.

AIM: Data on cardiovascular outcomes in elderly using proton pump inhibitors (PPI) are scant. We aimed to test the association between PPI use and the occurrence of first-time ischemic stroke (FTIS) among elderly. METHODS: The electronic database of a centrally located district branch of a large health maintenance organization in Israel was retrospectively screened (2002-2016) for community-dwelling individuals (≥65-95 years) for demographics and co-morbidities. Follow-up was until FTIS, death or end of study. Findings were analyzed by PPI use and occurrence of FTIS. RESULTS: 29,639 subjects (without history of stroke and use of antiplatelet aggregation drugs) mean age of 82.2 ± 5.5 years (range: 65-95 years, 38% male) were analyzed: 8,600 (29%) used PPIs. Mean follow up was 10.58 years (SD ± 5.44). Similar total and annual occurrence rates of FTIS were depicted in PPI users and non-users (20.9% vs. 21% and 2% vs. 2.1%, respectively). On a Cox regression analysis, upon adjustment for age, gender and cardiovascular disease related risk factors, PPI use was significantly associated with lower rates of FTIS (HR 0.73, 95% C.I. 0.69-0.77, p < 0.001). The risk for FTIS was significantly lower in subjects using PPI at any dose and for any time period compared to non-users (HR 0.9, 95% C.I. 0.85-0.96 for 7-48 yearly prescriptions and HR 0.51, 95% C.I. 0.46-0.55 for ≥49 yearly prescriptions). CONCLUSIONS: PPI use was associated with lower rates of FTIS in community-dwelling elders. Prospective large-scale studies are needed to fully elucidate the effect of PPI in this aging population.

Anorectal manometry may be performed by a nurse or physician, yet little has been written about what training is needed. Additionally, many gastroenterology nurses receive little exposure to motility studies such as anorectal manometry, limiting their ability to learn these procedures. We therefore sought to evaluate whether a short didactic course on anorectal manometry would increase nurses' knowledge about the procedure and stimulate their interest in becoming trained to perform it. To accomplish this, gastroenterology nurses attended a series of three lectures on anorectal manometry. A 15-question quiz was given as a pre-test and again as a post-test after completing the course. Thirteen nurses participated (11 female, mean age 46). None had experience performing anorectal manometry. Due to the course, test scores increased from a mean of 8.4 (55.9%) correct to 13.3 (88.7%) (p < .001), with improvements noted in 12 of 13 participants (92.3%). All of the nurses felt that the course increased their knowledge of anorectal manometry and reported that they would recommend it to other nurses. Most (61.5%) also expressed an interest in becoming trained to perform anorectal manometry. In conclusion, a short didactic course has been shown to increase nurses' knowledge and interest in performing anorectal manometry.

ABSTRACT: This article discusses the "bidirectional" relationship between inflammatory bowel disease (IBD) and physical activity. Intestinal symptoms and extraintestinal manifestations of IBD negatively impact a patient's ability to participate in sports. IBD also impacts athletic performance via its effects on muscle mass, muscle function, bone density, and fatigue. Surveys of IBD patients consistently show that IBD interferes with athletic participation. While IBD negatively affects physical activity, there is growing evidence that physical activity can be beneficial for IBD patients. Prospective studies have revealed that structured physical activities may positively influence inflammatory markers, disease activity, muscle strength, bone density, fatigue, stress, anxiety, and quality of life. This suggests that physical activity may be a simple and safe adjuvant therapy for IBD patients. Future studies assessing the optimal activity regimen are warranted. Finally, a cohort of professional athletes with IBD are described for the first time - football players in the National Football League.

OBJECTIVES: Small bowel involvement in Crohn disease (CD) is clinically important for diagnosis and treatment. Single and double-balloon enteroscopy have already become important diagnostic tools in such cases. The on-demand NaviAid AB device enables deep advancement into the small bowel, using an anterograde or retrograde approach. In adults, this procedure is feasible, safe, and rapid. This work aimed to assess the safety and feasibility of NaviAid AB enteroscopy in pediatric patients. METHODS: Single-center, prospective study using the through-the-scope balloon-assisted-enteroscopy (TTS-BAE) NaviAid AB device for the evaluation of the small bowel in children with suspected or known inflammatory bowel disease (IBD). The system consists of a single-use balloon catheter inserted through the instrument channel of a standard colonoscope. It consists of an inflation/deflation system (NaviAid SPARK), which is inflated to anchoring pressure. The repetitive push-pull technique enables the advancement of the colonoscope along the small intestine. RESULTS: Fifty analyzed endoscopic procedures (30 retrograde, 20 anterograde) were performed in 34 children (52.9% boys, mean age 13.7 years). Average maximal depth of insertion (MDI), advancement depth using the NaviAid AB and average total procedure time were 138âcm (range 100-190âcm), 81âcm (range 40-120âcm), and 12.8âminutes (range 7.3-19.0âminutes), respectively, for the anterograde approach and 143âcm (range 100-170âcm), 64âcm (range 20-95âcm), and 21.9âminutes (range 13.9-32.0âminutes), respectively, for the retrograde approach. No serious or device-related adverse events were reported. CONCLUSIONS: NaviAid AB enteroscopy in children is safe, feasible, and enables assessment of the small intestine in a short period of time.

BACKGROUND AND AIMS: Colorectal cancer (CRC) is largely preventable with routine screening and surveillance colonoscopy; however, interval cancers arising from precancerous lesions missed by standard colonoscopy still occur. An increased adenoma detection rate (ADR) has been found to be inversely associated with interval cancers. The G-EYE device includes a reusable balloon integrated at the distal tip of a standard colonoscope, which flattens haustral folds, centralizes the colonoscope's optics, and reduces bowel slippage. The insufflated balloon also aims to enhance visualization of the colon during withdrawal, thereby increasing the ADR. METHODS: In this randomized, controlled, international, multicenter study (11 centers), patients (aged ≥50 years) referred to colonoscopy for screening, surveillance, or changes in bowel habits were randomized to undergo either balloon-assisted colonoscopy by using an insufflated balloon during withdrawal or standard high-definition colonoscopy. The primary endpoint was the ADR. RESULTS: One thousand patients were enrolled between May 2014 and September 2016 to undergo colonoscopy by experienced endoscopists; 803 were finally analyzed (standard colonoscopy n = 396; balloon-assisted colonoscopy n = 407). Baseline parameters were similar in both groups. Balloon-assisted colonoscopy provided a 48.0% ADR compared with 37.5% in the standard colonoscopy group (28% increase; P = .0027). Additionally, balloon-assisted colonoscopy provided for a significant increase in detection of advanced (P = .0033) flat adenomas (P < .0001) and sessile serrated adenomas/polyps (P = .0026). CONCLUSION: Balloon-assisted colonoscopy yielded a higher ADR and increased the detection of advanced, flat, and sessile serrated adenomas/polyps when compared with standard colonoscopy. Improved detection by the G-EYE device could impact the quality of CRC screening by reducing miss rates and consequently reducing interval cancer incidence. (Clinical trial registration number: NCT01917513.).

INTRODUCTION: Treatment of Helicobacter pylori (Hp) infection remains a challenge for both primary care physicians and gastroenterologists. Over the past years, resistance of Hp to antibiotics has increased in Israel and abroad. Macrolide resistance remains the single most important factor responsible for failure to eradicate the organism. Effective treatment for the eradication of Hp must consider local resistance patterns. For this reason, representatives with clinical and research experience in the field of Hp convened under the auspices of the Israel Gastroenterology Association (IGA) to review the medical literature regarding the diagnosis and treatment of Hp, with particular emphasis on studies emanating from our region, and to develop local guidelines. The IGA does not recommend the use of clarithromycin-based triple therapy for the first-line treatment of Hp infection. Options for the first-line treatment of Hp infection include concomitant therapy, bismuth-based quadruple therapy and sequential therapy. Additional recommendations highlight the need to treat Hp whenever it is diagnosed, given its oncogenic potential, while adhering to the outlined indications for testing. The IGA calls for prospective studies to assess the comparative efficacy of different treatment protocols in Israel.

Biological inflammatory bowel disease (IBD) medications, once limited to intravenous (IV) administration, can now be administered both via IV and subcutaneously (SC). This study investigates patient preferences, willingness to switch from IV to SC, and associated factors. A questionnaire covering demographics, disease-related inquiries, quality of life, and IBD medication preferences was distributed via email, the Israeli Crohn's Disease and Ulcerative Colitis Foundation, infusion centers, and clinics. From 454 IBD patients (median age: 42 years; 55.7% female), responses revealed a preference for SC every 8 weeks, which is comparable to daily oral dosing. Both options were significantly favored over IV every 8 weeks and SC every 2 weeks, with no statistically significant differences between the latter two. However, among patients who were experienced with both SC and IV administration, a clear preference for SC administration every 2 weeks over IV every 8 weeks surfaced. Among IV-treated patients, 54.5% resisted switching to SC. Key reasons for this included medical staff presence (57.7%), a fear of needles (46.4%), belief in infusion efficacy (37.1%), and longer intervals between infusions (36.1%). Findings suggest that transitioning from IV to SC treatment is challenging due to patient resistance, which is influenced by specific factors. Identifying and addressing these obstacles is crucial for optimizing IBD management.
RESUMEN
BACKGROUND: Studies on the effect of computer-aided detection (CAD) in a daily clinical screening and surveillance colonoscopy population practice are scarce. The aim of this study was to evaluate a novel CAD system in a screening and surveillance colonoscopy population. METHODS: This multicentre, randomised, controlled trial was done in ten hospitals in Europe, the USA, and Israel by 31 endoscopists. Patients referred for non-immunochemical faecal occult blood test (iFOBT) screening or surveillance colonoscopy were included. Patients were randomomly assigned to CAD-assisted colonoscopy or conventional colonoscopy; a subset was further randomly assigned to undergo tandem colonoscopy: CAD followed by conventional colonoscopy or conventional colonoscopy followed by CAD. Primary objectives included adenoma per colonoscopy (APC) and adenoma per extraction (APE). Secondary objectives included adenoma miss rate (AMR) in the tandem colonoscopies. The study was registered at ClinicalTrials.gov, NCT04640792. FINDINGS: A total of 916 patients were included in the modified intention-to-treat analysis: 449 in the CAD group and 467 in the conventional colonoscopy group. APC was higher with CAD compared with conventional colonoscopy (0·70 vs 0·51, p=0·015; 314 adenomas per 449 colonoscopies vs 238 adenomas per 467 colonoscopies; poisson effect ratio 1·372 [95% CI 1·068-1·769]), while showing non-inferiority of APE compared with conventional colonoscopy (0·59 vs 0·66; p<0·001 for non-inferiority; 314 of 536 extractions vs 238 of 360 extractions). AMR in the 127 (61 with CAD first, 66 with conventional colonoscopy first) patients completing tandem colonoscopy was 19% (11 of 59 detected during the second pass) in the CAD first group and 36% (16 of 45 detected during the second pass) in the conventional colonoscopy first group (p=0·024). INTERPRETATION: CAD increased adenoma detection in non-iFOBT screening and surveillance colonoscopies and reduced adenoma miss rates compared with conventional colonoscopy, without an increase in the resection of non-adenomatous lesions.

Background/Aims: Clinical rates of fecal incontinence (FI) are known to vary based on race and ethnicity. It is unclear if anorectal manometry (ARM) findings in patients with FI differ based on ethnicity. Methods: High-resolution ARM studies performed between 2014-2021 due to FI at 2 hospitals with multiethnic populations were retrospectively reviewed. Results: Four hundred and seventy-nine subjects were included--87 (18.2%) Arab Israelis, 76 (15.9%) immigrants from the former Soviet Union, and 316 (66.0%) Jewish Israelis. Median age was 67 years old (76.0% women: 90.4% were parous). The Arab Israeli group had higher rates of smoking, diabetes, and obesity. Over 95% of ARM's were abnormal per the London classification including 23% with "combined anal hypotension and hypocontractility," 36% with "anal normotension with anal hypocontractility," 67% with "dyssynergia," and 65% with either "rectal hyposensation" or "borderline rectal hyposensation." On univariate analyses, significant differences between the ethnic groups were noted in the rates of "anal hypotension with normal contractility," "combined anal hypotension with anal hypocontractility," and "dyssynergia." In multivariate logistic regression analyses controlling for age, gender, parity, smoking, diabetes, and obesity, the Arab Israeli group remained several times more likely to have "combined anal hypotension and hypocontractibility" compared to the other groups. Conclusions: Ethnicity impacts ARM findings in patients with FI. The reason for this is unclear and future studies on ethnically diverse populations evaluating the clinical relevance of these findings are warranted.
