Predictors of recurrent bile duct stone after clearance by endoscopic retrograde cholangiopancreatography: A case-control study.

BACKGROUND: Recurrent common bile duct (CBD) stone is a long-term sequalae among patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with CBD stone extraction. Data regarding risk factors for recurrent CBD stone are scarce. We aimed to identify predictors of recurrent CBD stone. METHODS: We performed a retrospective case-controlled study from January 2010 to December 2019. Inclusion criteria included patients who had recurrent CBD stone at least 6 months after the index ERCP, in which complete stone extraction was performed and normal cholangiogram was obtained. Overall, 457 patients were included. Forty-two patients (9.2%) had recurrent CBD stone, and 415 patients (90.8%) did not have recurrent CBD stone. RESULTS: In univariate analysis, male sex [odds ratio (OR) = 0.49, P = 0.033] was a protective factor, while endoscopic stone extraction by basket vs. balloon (OR = 2.55, P = 0.005), older age (OR = 1.03, P = 0.003), number of CBD stones (OR = 1.99, P = 0.037), size of CBD stone (OR = 4.06, P = 0.003) and mechanical lithotripsy (OR = 9.22, P = 0.004) were risk factors for recurrent CBD stone. In multivariate logistic regression analysis, mechanical lithotripsy [OR = 9.73, 95% confidence interval (CI): 1.69-55.89, P = 0.010], basket clearance vs. combined basket and balloon (OR = 18.25, 95% CI: 1.05-318.35, P = 0.046) and older age (OR = 1.02, 95% CI: 1.00-1.05, P = 0.023) were risk factors, and male sex (OR = 0.39, 95% CI: 0.19-0.81, P = 0.012) was a protective factor. CONCLUSIONS: We identified modifiable and non-modifiable risk factors for recurrent CBD stone. Taking into consideration those factors might aid in minimizing the CBD stone recurrence risk.

Scheduled percutaneous endoscopic gastrostomy tube replacement did not reduce PEG-related complications.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) tube insertion is used for enteral nutrition. Each manufacturer has its own instructions for planned tube replacement. Accordingly, caregivers have adopted the policy of elective change at a fixed period of time (3-6 months). AIM: The current study aimed to assess whether retained PEG for more than 6 months was associated with a higher rate of PEG-related complications. METHODS: A retrospective single-center study included all patients who underwent PEG insertion were included in the study. RESULTS: Overall, 303 patients were included, 48 patients (16.2%) had PEG tube replacement. Peristomal PEG tube leak was the commonest complication, occurring in 20 patients (41.7%), followed by dislodgement in 18 patients (37.5%) and obstruction in 10 patients (20.8%). Among the patients with a leak, it occurred within and beyond 6 months from PEG insertion in 40 and 60% of patients, respectively (OR 0.68, 95% CI 0.21-2.18, p = .57). Similarly, 50% of patients had PEG tube obstruction within 6 months and 50% had it beyond 6 months from insertion (OR 1.46, 95% CI 0.34-6.26, p = .72). Moreover, there was no difference in PEG dislodgement after PEG insertion within or beyond 6 months (nine patients, 50% vs. nine patients, 50%), respectively, (OR 1.37, 95% CI 0.42-4.47, p = .76). CONCLUSION: Retained PEG tubes for more than 6-months were not associated with more PEG-tube-related complications.

The Yield of String Sign in Differentiating Mucinous from Non-Mucinous Pancreatic Cysts: A Retrospective Cross-Sectional Study.

Background and Objectives: The diagnosis of pancreatic cysts is mostly based on a combination of morphological appearance and fluid analysis of amylase and carcinoembryonic antigen (CEA). We aimed to assess the capability of the string sign in differentiating mucinous from non-mucinous pancreatic cysts. Materials and Methods: All patients who were referred for endoscopic ultrasound (EUS) for pancreatic cysts assessment from 2015 to 2020 were retrospectively analyzed. Results: Our cohort consisted of 112 patients. Of them, 92 patients (82.1%) had mucinous cystic neoplasms (group A) and 20 patients (17.9%) had non-mucinous cystic neoplasms (group B). The average age in groups A and B was 71.3 and 60.4 years, respectively. String sign was positive in 47 patients (51.1%) and negative in 21 patients (22.8%) in group A, while in group B, string sign was negative in 19 patients (95%). String sign showed significant correlation with the diagnosis of mucinous cystic neoplasms (OR 64.2, 95% CI 8.1-508.6, p = 0.0001). Cytology confirmed mucinous cystic neoplasms that included 32 patients; the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of string sign for mucinous cystic neoplasms were high, reaching 93.8%, 85.7%, 96.8%, and 75%, respectively, with an excellent accuracy rate of 92.3%. Conclusions: The string sign is highly accurate for predicting pancreatic mucinous cystic neoplasms, and should be used as an important aid for improving diagnostic accuracy.

Same day endoscopic retrograde cholangio-pancreatography immediately after endoscopic ultrasound for choledocholithiasis is feasible, safe and cost-effective.

BACKGROUND: Patients with suspected choledocholithiasis should undergo further confirmatory imaging test by endoscopic ultrasound (EUS) or magnetic resonance cholangiopancreatography (MRCP) before performing definite extraction by endoscopic retrograde cholangiopancreatography (ERCP). Usually, those procedures are performed at a separate session. AIM: The aim of our study is to report the safety, efficacy and cost-effectiveness of same day EUS and ERCP. METHODS: A retrospective study including all patients who underwent EUS and ERCP for choledocholithiasis from 1st January 2020 through 1st January 2021. Patients were categorized into same day EUS and ERCP (group A) and separate day procedures (group B). Univariate descriptive analysis was done to compare between the groups and cost-effectiveness analysis was based on the length of hospitalization. RESULTS: Sixty-one patients (57.5%) underwent same day EUS and ERCP (group A), as compared to 45 patients (42.5%) who had separate sessions (group B). The average ages in groups A and B were 66.1 ± 20.7 years and 65.8 ± 19.3 years, respectively (p = .47). There was no difference in the mean doses of midazolam, propofol and fentanyl in EUS and ERCP examinations in both groups. Notably, group A had a significantly lower hospitalization length as compared to group B (7.4 ± 2.9 vs. 9.7 ± 3.9 days, p = .0003). Consequently, same day EUS and ERCP was associated with a significant cost saving as compared to group B (7680.9$ ± 3071.4$vs 10089.4$±4053.4$, p = .0003), respectively. There was no serious anesthesia related adverse events. CONCLUSION: Same day EUS and ERCP for choledocholithiasis was safe and cost-effective with significant lower hospitalization length.

Nonattendance to gastroenterologist follow-up after discharge is associated with a thirty-days re-admission in patients with inflammatory bowel disease: a multicenter study.

BACKGROUND: Inflammatory bowel disease (IBD) is a set of chronic inflammatory diseases associated with significant morbidity and high hospitalization rate. IBD patients are particularly prone to rehospitalization resulting in high medical cost and morbidity. The aim of this study was to assess laboratory and clinical predictors of readmission in patients who were hospitalized with IBD flare. METHODS: A multicenter, retrospective, cross-sectional analysis included IBD patients who were admitted with disease exacerbation from January 1, 2019 to January 1, 2020 in three Israeli university hospitals (Nazareth Hospital, Galilee Medical Center and Hadassah Medical Organization). RESULTS: Overall, a total of 176 hospitalizations for IBD flares were included. Seventeen patients were readmitted within 30 days after discharge (group A), as compared to 159 patients who were not (group B). The average age was 35.3±19.2 years in group A vs. 38.6±16 years in group B. Eight (47.1%) and 9 (52.9%) patients had Crohn's disease (CD) and ulcerative colitis (UC) in group A as compared to 102 (64.2%) and 57 (35.9%) in group B, respectively. On univariate analysis, only the attendance to gastroenterology clinic follow-up after discharge from hospitalization due to IBD flare was significantly protective factor to with 30-days readmission (OR=0.37, 95% CI: 0.13-1, P=0.05). There were no associations with the other assessed clinical and laboratory parameters and importantly IBD type (OR=1.99, 95% CI: 0.74-5.34, P=0.17). Notably, there was no effect of the day of discharge white blood counts, albumin and C reactive protein (CRP) values on readmission rates (odds ratio [OR]=1.07, 95% CI: 0.96-1.20, P=0.19, OR=0.86, 95% CI: 0.39-1.91, P=0.71 and OR=0.99, 95% CI: 0.97-1.01, P=0.59), respectively. CONCLUSIONS: Attendance to out-patient gastroenterologist follow-up is the only significant protective parameter to 30-days readmission in patients with IBD. This finding highlights the vital need of adequate gastroenterological follow-up of these patients after hospital discharge. Further studies are warranted to precisely define timing and role of outpatient follow-up in reducing IBD readmissions.

Pancreatic and hepatobiliary manifestations of nonalcoholic fatty pancreatic disease: a referral multi-center experience.

BACKGROUND: Nonalcoholic fatty pancreatic disease (NAFPD) is an increasingly recognized disease with accumulating evidence of associated co-morbidities. However, data linked with other pancreatic and hepatobiliary disorders are still being studied. AIMS: To investigate the association of pancreato-hepato-biliary disorders with NAFPD. METHODS: At two Israeli medical centers, a total of 569 patients were analyzed who underwent endoscopic ultrasound for hepatobiliary indications. They were divided into groups depending on the presence or absence of NAFPD. RESULTS: Seventy-eight patients (13.7%) had NAFPD (NAFPD group) vs. 491 patients (86.3%) without (non-NAFPD group). NAFPD was significantly associated with obesity [odds ratio (OR) 4.98, 95% confidence interval (CI) 3.02-8.24, P < 0.0001], hypertension (OR 2.55, 95% CI 1.57-4.15, P = 0.0002), active smoking (OR 2.02, 95% CI 1.04-3.93, P = 0.03), and hyperlipidemia (OR 2.86, 95% CI 1.58-5.18, P = 0.0005). On multivariate regression analysis: fatty liver (OR 5.49, 95% CI 2.88-10.49, P < 0.0001), main duct intraductal papillary mucinous neoplasm (M-IPMN) (OR 2.69, 95% CI 1.05-6.9, P = 0.04), and gallstones (OR 1.93, 95% CI 1.1-3.38, P = 0.02) were the most endoscopically and ultrasonographically detected diseases that significantly correlated with NAFPD. CONCLUSION: NAFPD was associated with several diseases, most importantly the premalignant M-IPMN. Further investigation for these coexisting diseases should be considered.

The interplay between gastrointestinal and cardiovascular diseases: a narrative review focusing on the clinical perspective.

Both cardiovascular and gastrointestinal disorders represent considerable health burden on community clinics and hospitals with overwhelming economic cost. An overlap in the occurrence of these disorders is encountered in daily practice. Both affect each other in bidirectional manner through several mechanisms including altered hemodynamics, systemic inflammation, bacterial overgrowth and interactions and adverse effects of medications. In addition, to the known overlap in the symptoms occurrence of upper gastrointestinal tract diseases and cardiovascular diseases (CVDs). Awareness of this interplay and its clinical manifestations optimizes patient management, and could prevent catastrophic consequences and even save lives. In this review, we highlighted the clinical aspects of this bidirectional association between gastrointestinal and CVDs aiming to shed light on this topic and improve patients' care.

Pancreatobiliary manifestations of nonalcoholic fatty liver disease: a retrospective case-control multicenter study.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) has become a major cause of chronic liver disease. Several extrahepatic manifestations have been reported in relation to NAFLD. However, data regarding pancreatobiliary manifestation are scarce. AIM: We aimed to explore the association of pancreatobiliary manifestation with NAFLD. METHODS: A retrospective multicenter study that included all patients who underwent an endoscopic ultrasound performed for hepatobiliary indications and for whom the endosonographer reported on the presence or absence of fatty liver. The endoscopic ultrasound reports were reviewed and all pathological findings were reported. RESULTS: Overall, 545 patients were included in the study, among them, 278 patients had fatty liver (group A) as compared to 267 who did not have (group B). The average age in group A was 64.5 ± 13.5 years vs. 61.2 ± 14.7 years in group B. Male sex constituted 49.6 and 58% in groups A and B, respectively. On multivariate analysis, fatty pancreas [odds ratio (OR) 4.02; P = 0.001], serous cystadenoma (SCA) (OR 5.1; P = 0.0009), mucinous cystadenoma (MCA) (OR 9.7; P = 0.005), side-branch intraductal papillary mucinous neoplasm (IPMN) (OR 2.76; P < 0.0001), mixed-type IPMN (OR 16.4; P = 0.0004), pancreatic neuroendocrine tumor (NET) (OR 8.76; P < 0.0001), gallbladder stones (OR 1.9; P = 0.02) and hilar lymphadenopathy (OR 6.8; P < 0.0001) were significantly higher among patients with NAFLD. After adjustment for fatty pancreas, the association remained significant for SCA (OR 3; P = 0.01), MCA (OR 4.6; P = 0.03), side-branch IPMN (OR 1.7; P = 0.02), mixed-type IPMN (OR 5.5; P = 0.01) and pancreatic NET (OR 4.5; P = 0.001). CONCLUSION: Pancreatobiliary manifestations are common among patients with NAFLD. Assessment of these coexistent manifestations should be considered in the setting of patients with NAFLD.

A validated score predicting common bile duct stone in patients hospitalized with acute calculus cholecystitis: a multi-center retrospective study.

BACKGROUND: Concomitant common bile duct (CBD) stone in the setting of acute calculous cholecystitis (ACC) should be suspected once abnormal liver indices are noticed. AIM: We aimed to identify predictors of CBD stone in patients hospitalized with ACC. METHODS: We performed a retrospective multi-center, case-controlled, study from 1st of January 2016 until the 31th of December 2018. Inclusion criteria included patients with an established diagnosis of ACC based on clinical, laboratory and radiological criteria and who had an endoscopic ultrasound (EUS) for suspected CBD stone. One-hundred and twelve patients were included, of these fifty-three patients (47.3%) were diagnosed with CBD stone by EUS. RESULTS: In univariate analysis, Age (OR 1.038, P = 0.001), total bilirubin (mg/dl) (OR 1.429, P = 0.02) and CBD width (mm) by US (OR 1.314, P = 0.01) were statistically significant in predicting CBD stone and remained significant in multivariate regression analysis. We developed a diagnostic score that included these three parameters, with assignment of weights for each variable according to the coefficient estimate. A low cut-off score of 0 was associated with sensitivity of 100% for CBD stone, whereas a high cut-off score of 3 was associated with sensitivity of 10% and specificity of 96.6% with a positive predictive value of 67% (ROC of 0.7558). We validated this score with an independent cohort (ROC of 0.7416) with a sensitivity of 46.6%, a specificity of 91.5% and a PPV of 87.1%. CONCLUSION: We recommend incorporating this score as an aid for stratifying patients with ACC into low or high probability for concomitant CBD stone.

Predictors of in-hospital mortality among patients with clostridium difficile infection: a multicenter study.

BACKGROUND: Clostridium difficile infection (CDI)-associated mortality is a major global health concern. Several clinical and laboratory parameters have been linked to poor prognosis in patients with CDI. In the current study, we aimed to assess the rate of in-hospital mortality among Israeli CDI patients and to look for clinical and laboratory parameters associated to death. METHODS: We performed a multicenter retrospective study enrolling all patients above 18-years old who were hospitalized for CDI or with diagnosis made during hospitalization in two regional, teaching hospitals in the north of Israel (Galilee Medical Center, Nahariya and the Nazareth Hospital, Nazareth, Israel), from January 1, 2015 until January 1, 2020. All files of eligible patients were reviewed for demographic (age, gender), medical history and laboratory tests. RESULTS: Overall, we included in the study 180 patients, among them 56 died in hospital due to CDI (group A) while 124 survived (group B). The average age in groups A and B was 77.02±13 vs. 71.5±19.1, respectively. On univariate analysis, several clinical and laboratory parameters were associated with in-hospital mortality, including: advanced age, renal failure, antibiotics treatment while on treatment for CDI, need for mechanical ventilation, level of hemoglobin, white blood cells (WBC) and neutrophils count, neutrophil/lymphocyte ratio, serum level of albumin, creatinine and C reactive protein. On multivariate logistic regression analysis, only 4 parameters showed statistically significant association with in-hospital mortality, including age (odds ratio [OR]: 6.97, 95%confidence interval [CI]: 4.94-8.72, P=0.003), renal failure (OR: 3.72, 95% CI: 1.22-11.24, P=0.02), WBC count (OR: 1.09, 95% CI: 1.02-1.16, P=0.008), and lower albumin level (OR: 47.62, 95% CI: 10.31-200, P<0.0001). CONCLUSIONS: In this retrospective, multicenter study, age, serum albumin level, leucocytes count, and renal failure were the main predictors of in-hospital mortality in patients with CDI. Thus, antibiotic use should be weighed carefully in elderly comorbid patients, at increased risk of mortality from CDI .Prospective multicenter randomized studies investigating the effect of albumin infusion on in-hospital death of CDI patients are needed, thus enabling us to direct monitoring and treatment accordingly.

A state-of-the-art comprehensive review summarizing the emerging data on endoscopic ultrasound-guided liver diseases management.

Liver diseases are among the most common diseases worldwide accounting for substantial morbidity and mortality. Most liver diseases necessitate radiological evaluation or accurate diagnosis and recently for management as well. In the last decade, the application of therapeutic endoscopic ultrasound (EUS) procedure has been increasingly utilized for the management of various liver diseases. In this comprehensive narrative review article, we provide systematic overview on EUS-guided therapeutic interventions in various liver diseases summarizing most updated data regarding technical success, outcomes and safety profiles. Overall, 35 articles have reported on the use of EUS in the treatment of liver diseases with excellent technical success, favorable radiological response and high safety profiles for EUS-guided treatment of solid and cystic liver lesion and for EUS-guided angiotherapy for gastric varices, except for EUS-guided cyanoacrylate glue injection which was associated with life-threatening fatal systemic embolization adverse events. This suggests that EUS-guided intervention is a new promising therapeutic intervention for the treatment of various liver diseases with durable effect and a limited potential for adverse events.

Oral manifestations of inflammatory bowel disease: the neglected piece of the puzzle.

Inflammatory bowel disease (IBD) is a chronic relapsing remitting autoimmune disease including Crohn's disease and ulcerative colitis. IBD is associated with various extra-intestinal manifestations including oral manifestation. To date, only limited studies addressing the characteristics of the oral manifestations are available. The aim of the present review is to report the oral manifestations and their characteristics in IBD. A Medline/PubMed and Embase databases search were conducted and all relevant studies were extracted and analyzed. Overall, the oral manifestations in IBD were mostly associated with Crohn's disease rather than Ulcerative colitis where their prevalence ranged from 8 to 50%. Specific lesions for Crohn's disease include mucosal tags, cobblestoning and deep linear ulcerations with vertical fissures, while for ulcerative colitis, pyostomatisis vegetans was more disease specific. Notably, most of the oral manifestations were unrelated to disease activity, however more data are needed to accurately assess this correlation. Oral manifestations among IBD patients are not uncommon as Crohn's disease account for most of them. More data are warranted to precisely characterize their prevalence and association to intestinal activity.

Proton Pump Inhibitor Use May Increase the Risk of Diverticulitis but Not It's Severity among Patients with Colonic Diverticulosis: A Multicenter Study.

Colonic diverticular disease, especially diverticulitis constitutes a major cause of hospitalization and an economic burden in developed countries. Proton pump inhibitors (PPIs) are among the commonest drugs used to treat several diseases affecting the upper gastrointestinal tract. A few studies have reported that the use of Proton Pump Inhibitors PPIs caused dysbiosis. In this study, we searched for a relationship between PPI use and the onset and severity of diverticulitis in patients with colonic diverticulosis. In a retrospective study, patients who were hospitalized for documented diverticulitis were enrolled as cases and compared with a control group of patients with uncomplicated diverticulosis. Overall, 613 patients who had a diagnosis of diverticulosis were included in the study, 217 of whom had diverticulitis. After multivariate analysis, the non-modifiable risk factors associated with diverticulitis included: age (p < 0.0001), hypertension (p < 0.0001), chronic renal failure (p = 0.007), diabetes mellitus (p < 0.0001), and left colon location (p = 0.02). However, among the modifiable factors, only PPI use (p < 0.0001) showed a significant association. Advanced disease severity (according to Hinchey classification of diverticulitis stages II-IV) was associated with aspirin use (p = 0.0004) and pan-colonic location (p = 0.02). PPI use was the only modifiable factor significantly associated with diverticulitis, but not with its severity, among patients with diverticulosis. This observation should be confirmed in future multicenter prospective studies.

Long-Term Safety of Endoscopic Biliary Stents for Cholangitis Complicating Choledocholithiasis: A Multi-Center Study.

BACKGROUND: Treatment of cholangitis complicating choledocholithiasis includes biliary sphincterotomy and stone extraction. In certain cases of elderly comorbid patients with high risk for definitive endoscopic treatment, biliary stenting is the only measure for relieving biliary obstruction. AIM: We aimed to report the safety of retained biliary stone. METHODS: a multi-center, retrospective case-control study conducted at two Israeli medical centers from January 2013 to December 2018 including all patients 18 years of age or older who underwent ERCP and biliary stent insertion for the treatment of acute cholangitis due to choledocholithiasis. RESULTS: Three-hundred and eight patients were identified. Eighty-three patients had retained long-term biliary stents of more than 6 months (group A) from insertion compared to 225 patients whose biliary stents were removed within a 6-month period (group B). The mean follow-up in group A was 66.1± 16.3 vs. 11.1 ± 2.7 weeks in group B. Overall complications during the follow-up were similar between groups A and B (6% vs. 4.9%, OR 1.24, Chi square 0.69). Similarly, the rate of each complication alone was not different when comparing group A to group B (3.6%, 1.2% and 1.2% vs. 2.7%, 0.44% and 1.8%) for cholangitis, stent related pancreatitis and biliary colic, respectively (Chi square 0.85). Even after 12 months, the rates of overall complications and each complication alone were not higher compared to less than 12 months (Chi square 0.72 and 0.8, respectively). CONCLUSION: endoscopic biliary stenting for cholangitis complicating choledocholithiasis is safe for the long-term period without increase in stent related complications.

A Comprehensive Narrative Review on the Evolving Role of Endoscopic Ultrasound in Focal Solid Liver Lesions Diagnosis and Management.

The implications of endoscopic ultrasound (EUS) have expanded considerably in recent years to cover more fields in invasive gastroenterology practice, as both an investigative and therapeutic modality. The utility of EUS in the diagnosis and management of focal liver lesions has gained a special attractiveness recently. The EUS probe proximity to the liver and its excellent spatial resolution enables real-time images coupled with several enhancement techniques, such as contrast-enhanced (CE) EUS. Aside from its notable capability to execute targeted biopsies and therapeutic interventions, EUS has developed into a hopeful therapeutic tool for the management of solid liver lesions. Herein, we provide a comprehensive state-of-the-art review on the efficacy and safety of EUS in the diagnosis and management of focal solid liver lesions. Medline/PubMed and Embase database searches were conducted by two separate authors (T.K. and W.S.), all relevant studies were assessed, and relevant data was extracted and fully reported. EUS-guided diagnosis of focal liver lesions by sonographic morphologic appearance and cytological and histopathological finding of biopsies obtained via fine needle aspiration/biopsy have been shown to significantly improve the diagnosis of solid liver lesions compared with traditional imaging tools. Similarly, EUS-guided treatment has been shown to consistently have excellent technical success, high efficacy, and minor adverse events. The evolving valuable evidences of EUS utility might satisfy the unmet need of optimizing management of focal solid liver lesions.

Unawareness of thromboprophylaxis is associated with low venous thromboembolism occurrence in hospitalized patients with acute inflammatory bowel disease flare.

BACKGROUND: Inflammatory bowel disease (IBD) is a set of chronic inflammatory diseases associated with significant morbidity. Generally, IBD patients have twice the risk of venous thromboembolism (VTE) compared to healthy controls. VTE can occur both, during hospital stay or after discharge. We aimed to assess the incidence among IBD patients who were hospitalized for disease exacerbation. METHODS: In a retrospective cross-sectional analysis all IBD patients who were admitted with disease exacerbation at Galilee Medical Center and Hadassah Medical Organization were included in the study. Excluding criteria was IBD with already known hypercoagulable state. RESULTS: One-hundred and sixteen patients with 176 admissions due to IBD flare were included in the study. The average age was 38.3±16.3 years. Sixty-six admissions (37.5%) occurred in patients with ulcerative colitis exacerbation and 110 in patients with Crohn's disease exacerbation (62.5%). Thirty-nine patients (22.1%) were smokers. Fifty-four patients (30.7%) and 68 patients (38.6%) were on previous (within 3 months) biological and steroid treatment, respectively. Twelve patients (6.8%) were on prophylactic subcutaneous anticoagulation (enoxaparin) throughout their hospital stay and only 3 patient (1.7%) developed in-hospital clinical VTE episode. The mean hospitalization length was 6.8±7.9 days and among patients who developed VTE episode, the length of stay was significantly higher as compared to patients without VTE episodes (36.7 vs. 6.3 days, P<0.0001). Notably, in-hospital IBD related-surgical procedure was the only risk factor for the development of VTE (Odds Ratio: 36.2; P=0.01). CONCLUSIONS: In-hospital VTE is rare among IBD patients admitted with exacerbation. Further studies are warranted to assess risk factors for in-hospital VTE development and to assess further the role of prophylactic anticoagulation among IBD patients with bloody diarrhea.

The Utility of Endoscopic Ultrasound Fine Needle Aspiration in Pancreatic Cystic Lesions Diagnosis.

The yield of biochemical analysis of pancreatic cysts fluid obtained via fine needle aspiration (FNA) is limited. We aimed to assess whether biochemical cyst analysis correlates with the endoscopic ultra-sonographic (EUS) diagnosis. A retrospective study including patients who underwent EUS-FNA was performed. Agreement level between EUS diagnosis and biochemical analysis was reported. One-hundred-and-eleven patients were included. For cyst CEA level, 42.4% of patients with endoscopic diagnosis of pancreatic mucinous cystic neoplasm (intraductal papillary mucinous neoplasm (IPMN) and mucinous cystic neoplasms (MCN)) had CEA level >192 ng/mL vs. 15.8% of patients who had another endoscopic diagnosis (chi square = 0.03) with poor agreement level (Kappa = 0.130). For the serous cystadenoma (SCA), the levels of amylase and CEA were defined as <250 unit/L and <5 ng/mL, respectively. Eight patients (57.1%) had amylase of <250 unit/L, while 42.9% had >250 unit/L (chi square = 0.007). The agreement level between EUS diagnosis of SCA and amylase level was poor (Kappa = 0.231). For cyst CEA level, 71.4% had CEA level <5 ng/mL vs. 28.6% who had CEA >5 ng/mL (chi square < 0.001) with fair agreement level (Kappa = 0.495). EUS-FNA for pancreatic cystic lesions poorly correlated with the EUS diagnosis. FNA should be considered in the setting of EUS worrisome findings.

A State-of-the-Art Review on the Evolving Utility of Endoscopic Ultrasound in Liver Diseases Diagnosis.

Liver diseases are amongst the most common diseases worldwide and manifest as a parenchymatic and/or biliary injury due to several causes as well as focal liver lesions, ranging from benign to malignant ones. The diagnosis of liver diseases is based mainly on biochemical and advanced imaging studies and, when required, on liver biopsy. Endoscopic ultrasound (EUS), which combines endoscopy and ultrasonography, is one of the main examination techniques used in gastroenterology as it is applied to evaluate abnormalities in the lumen of the upper and lower gastrointestinal tract and to define pancreatic and hepato-biliary features, often in chronic patients. Given its high spatial resolution and its proximity to the liver, EUS is gaining popularity in the diagnostic work up of liver diseases. This is a comprehensive overview of the current literature on the diagnostic indications for EUS use in patients with liver diseases. We performed a MEDLINE\PubMed and Embase search, and all articles that were relevant, after reviewing abstracts, were assessed and the full text was analyzed to extract data regarding technical success, diagnostic yield, bioptic characteristics, and complications rate. EUS-guided imaging and biopsy techniques in liver diseases have shown consistent favorable promising results among the reports through the literature, with an excellent diagnostic yield and safety profile, especially in the context of focal lesions and portal hypertension. The application of EUS in the diagnosis of liver diseases is a promising technique and should be considered as a first-line therapeutic option in selected cases.

Bedside score predicting retained common bile duct stone in acute biliary pancreatitis.

BACKGROUND: Retained common bile duct (CBD) stone after an acute episode of biliary pancreatitis is of paramount importance since stone extraction is mandatory. AIM: To generate a simple non-invasive score to predict the presence of CBD stone in patients with biliary pancreatitis. METHODS: We performed a retrospective study including patients with a diagnosis of biliary pancreatitis. One hundred and fifty-four patients were included. Thirty-three patients (21.5%) were diagnosed with CBD stone by endoscopic ultrasound (US). RESULTS: In univariate analysis, age (OR: 1.048, P = 0.0004), aspartate transaminase (OR: 1.002, P = 0.0015), alkaline phosphatase (OR: 1.005, P = 0.0005), gamma-glutamyl transferase (OR: 1.003, P = 0.0002) and CBD width by US (OR: 1.187, P = 0.0445) were associated with CBD stone. In multivariate analysis, three parameters were identified to predict CBD stone; age (OR: 1.062, P = 0.0005), gamma-glutamyl transferase level (OR: 1.003, P = 0.0003) and dilated CBD (OR: 3.685, P = 0.027), with area under the curve of 0.8433. We developed a diagnostic score that included the three significant parameters on multivariate analysis, with assignment of weights for each variable according to the co-efficient estimate. A score that ranges from 51.28 to 73.7 has a very high specificity (90%-100%) for CBD stones, while a low score that ranges from 9.16 to 41.04 has a high sensitivity (82%-100%). By performing internal validation, the negative predictive value of the low score group was 93%. CONCLUSION: We recommend incorporating this score as an aid for stratifying patients with acute biliary pancreatitis into low or high probability for the presence of CBD stone.

Predictors of endoscopic intervention in upper gastrointestinal bleeding patients hospitalized for another illness: a multi-center retrospective study.

BACKGROUND: To characterize variables that may predict the need for endoscopic intervention in inpatients admitted for several causes who during the hospitalization developed acute non-variceal upper gastrointestinal bleeding (NVUGIB). METHODS: A retrospective analysis of inpatients who underwent upper gastro-intestinal endoscopy for acute NVUGIB while hospitalized for other causes from 1 January 2016 to 1 December 2017, was performed. In the primary outcome analysis, patients (N.=14) who underwent endoscopic intervention (group A) were compared to those (N.=87) who did not need for endoscopic intervention (group B). Secondary outcome analysis included patients who had significant endoscopic findings compared to those who did not have them. RESULTS: Multivariate regression analysis showed that in the primary outcome analysis, two parameters were significant: the number of packed red blood cells (PRBC) units transfused (odds ratio [OR]: 1.5, P=0.01) and Rockall Score (RS) (OR: 1.4, P=0.06) with receiver operator characteristic (ROC) curve of 0.7844. In the secondary outcome analysis, only the use of proton pump inhibitor drugs at admission was associated with protective effect for the development of significant endoscopic findings (odds ratio [OR]: 0.42, P=0.05) with ROC curve of 0.7342. CONCLUSIONS: In hospitalized patients, in case of de novo NVUGIB, the number of PRBC units transfused and RS are predictive of significant endoscopic findings.
