RESUMO
BACKGROUND: Gastrointestinal angiodysplasia (GIAD) is a rare diagnosis among the general population. We aimed to identify risk factors for GIADs and to determine the frequency rate in the general population. METHODS: A population-based retrospective study was performed including patients diagnosed with upper (stomach/duodenum) or lower (small bowel/colon) GIADs based on diagnostic codes from a large health maintenance organization. Control groups were matched for age and gender. Additional data including demographics, comorbidities, malignancies, and medications were collected. RESULTS: 991 upper GIADs and 3336 lower GIADs were included, compared to 7217 and 32,802 controls. The overall prevalence of GIAD was 0.092 %. 88 % of the upper and 85 % of the lower GIADs were diagnosed at ages ≥60, peaking at a prevalence of 0.37 % for ages 71-80. The most significant risk factors for GIADs included liver cirrhosis (OR 4.0 for lower GIAD and OR 7.0 for upper GIAD, p < 0.001), hypertension (OR 2.3 for lower GIAD and OR 2.8 for upper GIAD, p < 0.001) and aortic stenosis (OR 2.8 for lower GIAD and OR 2.0 for upper GIAD, p < 0.001). Other significant risk factors included ischemic heart disease, chronic renal failure, female gender, and chronic obstructive pulmonary disease. Interestingly, both upper and lower GIADs were found to be significantly less frequent in patients with malignancy. CONCLUSION: Identification of the clinical conditions and demographic factors associated with GIAD may improve our understanding of the etiology and the optimal treatment modalities for this rare condition.
RESUMO
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.

BACKGROUND AND AIMS: Prior studies have identified predictors of inadequate preparation with limited success. We aimed to build a model that could predict the likelihood of inadequate preparation by also including factors related to the patient's reaction to drinking the laxative preparation. METHODS: Demographic, clinical, and preparation-related data were prospectively collected on patients undergoing colonoscopy. An inadequate preparation was defined as a Boston Bowel Preparation Scale < 6. Statistical analyses were performed to identify predictors of inadequate preparation and create a predictive model. RESULTS: 324 patients were included (age 67 +/- 14 years, 52% male). 77 (23.7%) had inadequate preparations. Diabetes (p < 0.001), cerebrovascular accident (CVA) (p < 0.001), incomplete prep consumption (p = 0.007), high school level education and above (p < 0.001), use of Bisacodyl (p = 0.005), >10 bowel movements (p = 0.02), and use of Sodium Picosulfate or low-volume polyethylene glycol (PEG) solution (2L) compared to PEG 3L (p < 0.001) were significant variables. In a multivariate analysis, prior CVA increased the risk for inadequate preparation (OR = 4.8, CI 1.6-14.5), whereas high school level education and above (OR = 0.4, CI 0.2-0.8), consumption of Bisacodyl (OR = 0.4, CI 0.2-0.8), >10 bowel movements (OR = 0.5, CI 0.3-0.9), and use of Sodium Picosulfate (OR = 0.5, CI 0.3-0.9) decreased the risk for inadequate prep. Using these, a predictive model for patients likely to have an inadequate colon preparation was created with an area under the curve of 0.74 (35% sensitivity, 90% specificity at a cutoff point of 39%). CONCLUSION: Given the low sensitivity, this predictive model does not appear ready for clinical use. However, due to its high specificity, it may be helpful in high-risk, sicker populations by preventing inadequately prepped procedures.
RESUMO
BACKGROUND: Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions and these may lead to increased intraluminal colonic pressure. AIM: To assess whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis. METHODS: We analyzed data from a study of patients undergoing colonoscopy for different indications from 2020 through 2021. Patients completed a structured questionnaire concerning previous abdominal surgeries, dietary and lifestyle exposures including smoking, alcohol use and co-morbidities. RESULTS: Three hundred and fifty-nine patients were included in the study. The mean age was 67.6 and 46% were females. Diabetes mellitus, hypertension, ischemic heart disease, chronic obstructive pulmonary disease, chronic renal failure, and body mass index were similar in the diverticulosis and control groups. The overall prevalence of colonic diverticulosis was 25% (91/359) and 48% of the patients had previous abdominal surgery. As expected, the prevalence of diverticulosis increased with age. There was no difference in the rate of previous abdominal surgery between patients with or without diverticulosis (49% vs 47%, P = 0.78). In regards to specific surgeries, inguinal hernia repair was significantly associated with diverticulosis (52% vs 20%, P = 0.001), but not diverticulitis. In contrast, appendectomy was not associated with diverticulosis (6% vs 14%, P = 0.048). CONCLUSION: These findings suggest that post-operative abdominal adhesions inducing high colonic intraluminal pressures do not appear to be the mechanism for diverticula formation. Rather, inguinal hernia and diverticulosis may share similar connective tissue pathologies with no causative relationship between them.
RESUMO
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.

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.
RESUMO
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: Achalasia is characterized by aperistalsis with poor relaxation of the lower esophageal sphincter (LES). We aimed to systematically assess whether LES metrics on high-resolution manometry (HRM) correlate with the symptomatic or endoscopic presentation of patients with achalasia. METHODS: A retrospective study was performed at two tertiary medical centers. All cases of newly diagnosed, untreated achalasia were reviewed for demographics, symptoms, and endoscopic findings. These were correlated with HRM metrics, including LES basal pressure (LESP), integrated relaxation pressure (IRP), percent LES relaxation, and esophagogastric junction (EGJ) morphology. RESULTS: 108 achalasia patients were included; 56 (51.9%) were men, with a mean overall age of 55.6 ± 17.9 years old. Achalasia subtypes included 23.1% with Type I, 65.7% Type II, and 11.1% Type III. Mean LESP was 40.9 ± 13.7 mmHg, IRP 26.8 ± 11.5 mmHg, with 36% ± 20% LES relaxation. On univariate analyses, a higher IRP was associated with age < 50 (p = 0.028), female sex (p = 0.030), Arab ethnicity (p < 0.001), weight loss (p = 0.016), a tortuous esophagus (p = 0.036), and resistance at the EGJ (p = 0.033). However, on multivariate regression analyses, only ethnicity remained significantly associated with IRP. No unique variables were associated with either LESP or percent LES relaxation. Achalasia subtype and Eckardt score were not associated with any LES metrics. Non-Type 1 EGJ morphology was associated with a lower LESP. CONCLUSIONS: LES metrics on HRM do not appear to correlate with the clinical or endoscopic presentation of patients with untreated achalasia.
RESUMO
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.

Background: Patients with absent contractility (AC) often suffer from either reflux or dysphagia. It remains unclear what factors determine which phenotype patients present with. We sought to evaluate if high-resolution manometry metrics, especially integrated relaxation pressure (IRP), could explain this. Methods: Cases of AC from three medical centers were reviewed for demographic, clinical, and manometric data. Cases with an IRP between 10−15 mmHg or subsequent diagnosis of achalasia were excluded. Results: 69 subjects were included (mean age 56.1; 71% female). A total of 41 (59.4%) were reflux-predominant. The reflux-predominant group was younger (51.1 vs. 63.5, p = 0.002) and had lower median LES basal pressures (7.5 vs. 12.5 mmHg, p = 0.014) and IRP values (1.5 vs. 5.6 mmHg, p < 0.001) compared to the dysphagia group. When divided into tertiles, the trend in symptoms between LES basal pressure tertiles was not significant. However, the trend for IRP was significant (p < 0.001). For example, in the lowest IRP tertile, 91.3% of subjects were reflux-predominant compared to only 26.1% in the highest tertile, while the dysphagia-predominant group increased from 8.7% to 73.9%. In a regression model controlling for age and using IRP tertile 1 as the reference, having an IRP in tertile 2 increased the likelihood of having dysphagia-predominant disease by 7, while being in tertile 3 increased the likelihood by 22. Conclusions: IRP helps distinguish between the reflux-predominant and dysphagia-predominant phenotypes of AC. This may have therapeutic clinical consequences as procedures such as fundoplication to tighten the LES may benefit patients with reflux and a low IRP, while procedures like peroral endoscopic myotomy (POEM) to disrupt the LES may benefit patients with dysphagia and a relatively high IRP.
RESUMO
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.

(1) Background: Absent contractility (AC) is an esophageal motility disorder defined as a normal integrated relaxation pressure with 100% failed peristalsis. We sought to clarify the natural history of this disorder and its relationship with rheumatologic diseases, such as systemic sclerosis (scleroderma). (2) Methods: We retrospectively identified patients with AC based on high-resolution manometry findings at three referral institutions and then matched them with controls with esophageal complaints who had normal manometries. (3) Results: Seventy-four patients with AC were included (mean age 56 years; 69% female). Sixteen patients (21.6%) had a rheumatologic disease. Compared to controls, patients with AC were significantly more likely to present with heartburn, dysphagia, vomiting, and weight loss. During follow-up, they were also more likely to be seen by a gastroenterologist, be diagnosed with gastroesophageal reflux disease, take a proton pump inhibitor, and undergo repeat upper endoscopies. No AC patients developed a new rheumatologic disease during follow-up. No significant differences were noted in the clinical presentation or course of AC patients with rheumatologic disease compared to those without. (4) Conclusions: Patients with AC have more esophageal symptoms and require more intense gastrointestinal follow-up than controls. Only a minority of patients with AC have underlying rheumatologic disease. Those without rheumatologic disease at baseline did not subsequently develop one, suggesting that a rheumatologic evaluation is likely unnecessary. The clinical course of AC in patients with rheumatologic disease and those without appears to be similar.
RESUMO
BACKGROUND: Direct-acting antiviral (DAA) regimens and telemedicine services are both options for treating hepatitis C virus (HCV) within the prison setting. We aimed to compare factors associated with HCV treatment success over the past decade in Israeli prisons, specifically the influence of DAAs and telemedicine. METHODS: We retrospectively reviewed the medical records of inmates with HCV infection in Israeli prisons from 2010 through 2020. Demographic, clinical, and laboratory data were recorded, including treatment regimens and success rates. RESULTS: A total of 273 inmates were treated; mean age 45 ± 9.36 years; 98.2% males; 63.9% with a history of drug abuse. Advanced fibrosis was documented in 42.9%. The most common genotypes were 1 (46%) followed by 3 (40.7%). Interferon-based regimens were given to 68 inmates between 2010 and 2017. DAA agents were introduced in 2016, with pan-genotype regimens being exclusively used since 2019. Telemedicine services were used in 140 patients (51.3%), starting in February 2019. The sustained viral response (SVR) rate with interferon-based therapy was 78.8% and 98.8% with DAA treatment, giving an overall SVR of 93.2%. This difference between regimens proved to be the only statistically significant predictor of treatment success. The number of prisoners being treated with DAAs increased exponentially after telemedicine was introduced. Comparable SVR rates were achieved with either in-person or telemedicine consultation. CONCLUSION: Screening of this high-risk population and using telemedicine for treatment may be an effective strategy for the elimination of HCV from the prison population.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic raised concerns among inflammatory bowel disease (IBD) patients fearing an increased risk of infection and poor outcomes. We aimed to evaluate the incidence of COVID-19 among IBD patients; its influence on disease severity and outcome; its relationship to medication use and how the pandemic affected IBD management. METHODS: An anonymous questionnaire was posted online to members of the Israel Crohn's Disease and Ulcerative Colitis Foundation (November 2020-January 2021). The questionnaire addressed the course of IBD disease and COVID-19 infection over the past year. RESULTS: Total 2152 IBD patients completed the questionnaire. Of which 104 (4.8%) had been infected with COVID-19, significantly lower than the 'expected' infected cases among the Israeli population (P = 0.033). The median age of participants was 39 years; 60.5% were female. Most patients (75.6%) had no comorbidities other than IBD. No correlation was found between IBD type or disease severity and COVID-19 infection. Most IBD patients reported mild COVID-19 disease, regardless of the type of IBD medications. Multivariable logistic regression analysis revealed that younger age, elevated BMI and diabetes were independent risk factors for COVID-19 infection. IBD treatment methods including 5-aminosalicylic acid, smoking and hypertension were protective factors. In total 25.2% of COVID-19 patients discontinued their IBD treatment, compared to 8.5% of non-COVID-19-infected patients. IBD flares were significantly higher in those who discontinued treatment (P < 0.001). CONCLUSIONS: IBD patients do not have an increased risk for COVID-19, regardless of IBD activity or treatment. Patients should be encouraged to continue effective IBD therapy, including biologics and steroids, to minimize active IBD.

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.

OBJECTIVE: Different infectious agents have been presumed to be candidates acting as an etiologic factor or trigger of Crohn's disease (CD). Group A Streptococcus (GAS) is a common human infection agent that can also trigger post-infectious immune-mediated conditions. The current study aimed to examine whether the immunogenic activity induced by GAS may trigger new-onset of CD. METHODS: Data for antistreptolysin O (ASO) level, throat culture for GAS, and history of streptococcal infection were collected from 91 patients with CD that were divided into three groups including; new-onset CD, CD in remission and active CD. The data were compared with the control group. RESULTS: All participants had negative results of throat culture for GAS and had no history of documented streptococcal infection in the past year. Our results indicate that new-onset CD, but not CD in remission or active CD, is associated with significantly increased positive ASO compared to controls. Half of the patients in the new-onset CD group were ASO positive, which was significantly higher compared to the control group in a univariant (OR: 4.00; 95% CI 1.27-12.58; P=0.02) and multivariant analysis (OR: 4.41; 95% CI 1.35-14.37; P=0.014). CONCLUSION: Our study is the first to focus on ASO levels in patients with CD and to demonstrate a significant association between ASO and new-onset of CD. Large prospective randomized controlled studies are needed to confirm the validity of this data and to further clarify the clinical significance of our findings.
