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.

The yield, effectiveness and safety of gastroscopy in management of early postbariatric upper gastrointestinal pain

BACKGROUND

Upper gastrointestinal (GI) symptoms are prevalent among patients after -bariatric surgeries. Gastroscopy is an important procedure to investigate symptoms. Our primary aim was to evaluate the yield, effectiveness and safety of gastroscopy procedure obtained in a 3-months period after bariatric operation for exploring upper GI symptoms origin.

METHODS

Single center, retrospective study at the EMMS Nazareth Hospital from 2010 to 2018. All patients who underwent gastric-bypass (either Roux-en-Y[R-en-Y] or Mini-gastric bypass [MGB]) and who experienced early upper GI symptoms were included in the study.

RESULTS

A total of 428 were included in the study. Among them, 154 patients (36%) underwent R-en-Y surgery and 274 (64%) underwent MGB. Baseline characteristics were similar in the two groups. The mean age in the R-en-Y group was 42.3±10.8 vs. 42.8±11.2 in the MGB group. Thirty-nine patients underwent gastroscopy, more in the R-en-Y group compared to MGB group (11.6% vs. 7.6%, P<0.005). In the MGB group, more patients had normal surgical anatomy (23.1%) vs. 12.8% in the R-en-Y group, and the prevalence of erosive esophagitis was 14.2% in the MBG group vs. 5.5% in the R-en-Y group, P<0.005. On the other hand, marginal ulcer was more frequent after R-en-Y than MGB surgery (16.6% vs. 9.5%, P<0.005). No procedural related complication was observed in both groups.

CONCLUSIONS

Upper GI symptoms in the early postbariatric surgery period are common with most endoscopic examination revealing normal postsurgical anatomy. In this setting, gastroscopy is safe, without procedural related complications.

Benign Hepatic Tumors: From Incidental Imaging Finding to Clinical Management

Benign hepatic tumors (BHTs) are commonly detected as incidental finding mainly due to the frequent utilization of imaging modalities, including ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). Rigorous clinical evaluation, with a particular focus on chronic liver disease (CLD) or risk factors for CLD, medication history, physical examination for signs of CLD, blood tests, and a review of past liver radiology constitute the initial steps in the evaluation of a new liver lesion. Further, contrast-enhanced imaging using US, CT and MRI, can be used depending on the clinical scenario and their availability. The contrast-enhanced MRI provides detailed tissue assessment while avoiding exposure to radiations, although it is scarcely available and expensive. While the liver tissue-specific protocols ensure precise diagnosis, a biopsy is recommended in selected or doubtful cases. Further, most BHTs, such as hemangiomas, are harmless and do not require special management or follow-up, the hepatic adenomas and large or atypical cases of focal nodular hyperplasia are clinically relevant and require management/follow-up. In such cases, it is favorable to have a multidisciplinary team approach, which includes hepatologist, radiologist, hepatobiliary surgeon, and pathologist. This review aims to elaborate the current understanding of BHTs, and provide a practical guidance for primary care and practitioners of family and internal medicine for the disease evaluation and management.

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.

The Role of Pre-Operative Neutrophil-to-Lymphocyte Ratio in Predicting Post Bariatric Surgery Related Complications

BACKGROUND

Bariatric surgery has become the most common and effective therapeutic option for obesity. However, it is associated with morbidity and complications. Identification of predictors for surgical complications is an unmet need.

OBJECTIVES

To determine a simple non-invasive parameter that predicts early postoperative complications following bariatric surgery.

METHODS

In this retrospective study of all patients who underwent elective bariatric surgery at Nazareth Hospital EMMS during a 4-year period (2015-2018). We collected clinical and laboratory parameters and determined predictors of complications.

RESULTS

A total of 345 patients underwent bariatric surgery during the study period. Of the patients, 51 experienced early post-bariatric surgery complications as compared to 294 patients who had no complications. Univariate analysis revealed that neutrophil-to-lymphocyte ratio (NLR) (odds ratio [OR] 1.912, P < 0.0001) and platelet to lymphocyte ratio (OR 1.015, P < 0.0001) were associated with post-bariatric surgery complications. In a multivariate logistic regression analysis, only NLR remained a significant predictor (OR 1.751, 95% confidence interval 1.264-2.425, P = 0.0008) with a receiver operating characteristic curve for NLR of 0.8404.

CONCLUSIONS

We found that the NLR predicts post bariatric surgery early complications. Further prospective studies are needed to validate our findings.

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.

A case of allergy to Silybum marianum (milk thistle) and Eragrostis tef (teff)

Background

This paper presents a peculiar first case of an allergy to Silybum marianum (milk thistle) and Eragrostis tef (teff). Both teff and milk thistle have been presented in the literature (both domestic and foreign) in a positive light, the former as a new part of gluten-free diet, and the latter as a treatment for a number of conditions, particularly those of the liver.

Case presentation

A 29-year-old male presented at our clinic due to an episode of itching and burning in his mouth, swollen tongue, and difficulty swallowing following ingestion of teff flakes. He also reported sneezing, runny nose, watering and burning eyes, and wheezing following inhalation exposure to ground milk thistle. The patient’s occupation is associated with exposure to these allergens. The patient underwent comprehensive allergy diagnostic assessments (including skin-prick testing, serum specific IgE levels, Faber test, spirometry, and acoustic rhinometry) and gastroenterological assessments. The diagnosis was established on skin tests with native allergens (milk thistle 16/35, teff flour 22/60, negative control 0/0, histamine 3/5) provided by the patient. There are no commercially available (standardized) tests for milk thistle or teff either in Poland or anywhere else in the world.

Conclusions

Milk thistle is available in the form of dry, finely-ground preparations (which are used as additives to bread, soups, and yoghurts) and extracts (which are used as ingredients in over-the-counter herbal remedies). Teff is a gluten-free cereal whose grains are rich in methionine, calcium, iron, folic acid, and antioxidants. This case report presents milk thistle and teff as potentially new allergens. A literature review revealed no similar allergy cases in Poland or elsewhere in the world.

Pre-endoscopic tachycardia predicts increased sedation dose and lower adenoma detection rate in patients undergoing endoscopic procedures: a case control study

BACKGROUND

Tachycardia prior to endoscopic procedures is commonly encountered which reflect patient anxiety status. Despite this frequent occurrence, it is unclear if in a patient with tachycardia sedation dose should be modified. The aim of our study was to assess the effect of pre-endoscopic tachycardia on sedation dose.

METHODS

A retrospective analysis of all patients who underwent upper endoscopy and colonoscopy at EMMS Nazareth hospital were performed. We excluded patients with diseases and medications affecting the heart rate.

RESULTS

A total of 2855 patients were included in the study. Two-hundred and thirty-seven patients had tachycardia before endoscopy (8.3%, group A) as compared to 2618 (group B) patients who had heart rate ≤100 beats per minute. The mean dosage of propofol in group A was significantly higher (62.6±33.2 mg vs. 57.4±29.9 mg) than in group B (P=0.01). There was no difference in the cecal intubation rate among the two groups (P=0.9). Notably, the adenoma detection rate was significantly lower among group A patients as compared to group B (13.6% vs. 22.8%, P=0.02) patients. There were no sedation related complications.

CONCLUSIONS

Tachycardia prior to endoscopic procedures was associated with higher sedative dosage and lower adenoma detection rate, however no major complications were recorded. These data should be taken into consideration to optimize procedure quality.

Can microscopic ileitis in patients with clinically suspected inflammatory bowel disease predict the future?

BACKGROUND

The implication of microscopic ileitis finding in patients referred for ileocolonoscopy for clinically suspected inflammatory bowel disease (IBD) is not well defined, and its correlation with clinical outcome has not been fully studied. The current study aims to determine the prognostic yield of biopsies in this setting, and to evaluate the correlation of microscopic ileitis with long-term clinical outcome.

METHODS

We reviewed endoscopic reports of patients referred to our department for ileocolonoscopy in the years 2010-2016, as part of a diagnostic work-up for suspected IBD. Patients whose ileocolonoscopies proved normal were included, provided that terminal ileum biopsies had been performed. Accordingly, patients were divided into groups classified as normal (normal or reactive changes) and microscopic ileitis (inflammation or ileitis of any severity). Both groups were followed prospectively to determine clinical outcome.

RESULTS

A total of 439 patients met the inclusion criteria. Sixty-four (14.6%) showed inflammation on biopsy and were included in the microscopic ileitis group. Age range and gender figures did not differ significantly between the groups. Overall follow-up period was 6.1 ± 2.3 years. Patients in the microscopic ileitis group were significantly associated with Crohn's diagnosis during the follow-up period compared with the normal group (19% vs 2%, OR = 11.98, 95%CI = 4.48-32.01; p < 0.01). Patients with granuloma or moderate-severe ileitis on biopsy were significantly associated with Crohn's development (100% vs 11%; P < 0.01) compared with mild or nonspecific inflammation.

CONCLUSION

The discovery of microscopic ileitis in clinically suspected IBD is associated with increased risk of future diagnosis of Crohn's disease.

Eosinophilic Esophagitis in Adults: A Concise Overview of an Evolving Disease

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease that encompasses esophageal symptoms along with eosinophilic infiltration of the esophageal epithelium. EoE is an evolving disease that has been a subject of interest to many researchers since the first studies recognized this condition as a new and distinct clinicopathological entity 25 years ago. Clinical presentation in adult patients may include dysphagia, food impaction, vomiting, and reflux symptoms. The diagnosis of EoE is based on the combination of clinical history suggestive of esophageal dysfunction, endoscopic features indicative of the disease, and histology revealing eosinophilic infiltration of the esophageal epithelium that persists after a trial of proton pump inhibitor therapy along with the exclusion of other disorders that may be associated with esophageal tissue eosinophilia. The interplay between EoE and gastroesophageal reflux disease (GERD) is complex, and differentiating these two conditions continues to be difficult and challenging in clinical practice. The mainstay treatment includes dietary modification, topical steroids, and/or endoscopic dilation. The primary care physician (PCP) plays an important role in improving patient care and quality of life by ensuring early referral and participating in management and follow-up. This article provides an overview of the current knowledge base regarding the disease including epidemiology, genetics, pathogenesis, common clinical presentations, the interplay between EoE and GERD, diagnostic approaches, and therapeutic options available to the PCP.

Chronic Constipation in the Elderly Patient: Updates in Evaluation and Management

Chronic constipation (CC) is a common disorder in the elderly population globally and is associated with comorbidities and negative implications on the quality of life. Constipation prevalence varies in different studies, primarily owing to the nonuniformity of the diagnostic criteria. However, 15%-30% of individuals aged >60 years are diagnosed with CC. Primary care physicians are the main healthcare providers that manage constipation in elderly patients in parallel with increased population aging and increased prevalence of constipation. Physical inactivity, polypharmacy, chronic medical conditions, rectal hyposensitivity, and defecatory disorders all play a role in the pathogenesis of CC in elderly patients. Detailed anamnesis, particularly history related to chronic medication use, with digital rectal examination may assist in identifying constipation causes. Additionally, blood tests and colonoscopy may identify organic causes of CC. Physiologic tests (i.e., anorectal manometry, colonic transit time with radiopaque markers, and defecography) can evaluate the physiologic function of the colon, rectum, and anus. However, generally, there are several causes of constipation in older patients, and an individualized approach is recommended. Treatment of chronic idiopathic constipation is empiric, based on the stepwise approach. Lifestyle advice, adjustment of chronic medications, and prescription of laxatives are the first steps of management. Several laxatives are available, and the treatment is evolving in the last decade. Biofeedback is an effective therapy especially for defecatory disorders. This review aimed to summarize the most updated knowledge for primary care physicians in the approach and management of CC in elderly patients.

Thyroid Dysfunction is Prevalent in Autoimmune Hepatitis: A Case Control Study

BACKGROUND

Autoimmune hepatitis (AIH) may be associated with other autoimmune diseases. Autoantibodies are common in AIH suggesting their potential role in the pathogenesis of the disease. Among these autoantibodies, thyroid autoantibodies have been reported in patients with chronic hepatitis, with greater prevalence in patients with chronic hepatitis C infection.

OBJECTIVES

To assess the prevalence of thyroid dysfunction among patients with AIH.

METHODS

In this case-control, retrospective study, we examined patients diagnosed with AIH according to both the original and revised international AIH group scoring systems. Patients with other hepatic pathologies were excluded AIH was evaluated as an independent risk factor for thyroid disease by a logistic regression model. Univariate and multivariate regression analyses were conducted using hypothyroidism and hyperthyroidism as the dependent variables.

RESULTS

Our cohort comprised 163 patients diagnosed with AIH and 1104 healthy age- and gender-matched controls. Hypothyroidism was more prevalent among those with AIH compared to controls (17.7% vs. 5%, respectively, 95% confidence interval [95%CI] 1.68-2.48, P <  0.001). Hyperthyroidism was more prevalent in AIH patients compared to controls (odds ratio 3.2% and 1.2%, respectively, 95%CI 1.68-2.47, P <  0.001). Using a multivariate logistic analysis, we found an independent association between AIH and hypothyroidism but not with hyperthyroidism.

CONCLUSIONS

Thyroid dysfunction is more prevalent in patients with AIH. Whether thyroid dysfunction is the cause or a risk factor for AIH, or vice versa, is still unclear. Screening for thyroid dysfunction is warranted after AIH is diagnosed.

The association between non-alcoholic fatty liver disease and valvular heart disease

BACKGROUND

Non-alcoholic fatty liver (NAFLD) disease has become the commonest cause of end-stage liver disease. Patients with NAFLD have an increased risk of associated extrahepatic conditions, including structural and functional cardiovascular disease. Still, it is unknown if there is an association between NAFLD and valvular heart disease (VHD). The aim of this paper was to determine the association between NAFLD and VHD.

METHODS

We performed a single center retrospective study in EMMS Nazareth Hospital from April 2010 to April 2018. All patients who were diagnosed with NAFLD and who had an echocardiography performed within one year were included. Subjects age and sex-matched, who had echocardiography performed in the same period were included in the control group.

RESULTS

The mean age of the NAFLD group was 41.5±11.7 vs. 42.8±10.8 years of the control group (P=0.2). The prevalence of aortic stenosis, aortic insufficiency, mitral stenosis and mitral insufficiency were significantly higher in NAFLD patients compared to the control group (1.2% vs. 0.22%, 1.32% vs. 0.32%, 0.66% vs. 0.27%, and 1.87% vs. 0.41%, respectively; P<0.001). In the multivariate logistic regression analysis, NAFLD was found to be independent risk factor for VHD (OR 2.39, 95% CI 2.17-2.78, P<0.001).

CONCLUSIONS

VHD was significantly seen more frequently in NAFLD patients compared to controls. Prospective studies are needed to validate our findings and to elucidate the pathogenesis of VHD in patients with NAFLD.

Eosinophilic esophagitis: pitfalls and controversies in diagnosis and management

Formerly considered a rare disorder, eosinophilic esophagitis (EoE) has emerged as a leading cause of feeding problems in children and an increasingly recognized cause of dysphagia and food impaction in adults. Our understanding of EoE and its complex interplay with gastro-esophageal reflux disease (GERD) has evolved over the past decade and culminated in the introduction of proton pump inhibitor (PPI) responsive EoE as a distinct entity which has added to this complexity. It is now clear that this entity is on the same spectrum as the original EoE, and that PPIs should be considered as part of treatment protocol and should not be recommended as a diagnostic tool. As such, removing the PPI trial from the diagnostic algorithm has been encouraged recently. Recent guidelines and reviews thoroughly address various aspects in EoE pathogenesis and diagnostic workup as well as management endpoints, treatment options and novel therapies. However, despite the recent extensive study and the advances in our knowledge of this disease, unmet needs and pitfalls in diagnostic workup and management of these patients are still to be clarified and will be under focus in this review.

Non-alcoholic fatty liver disease: a survey of involvement of primary care physicians

BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are neglected in most patients' electrical medical report by their family physicians (FP). We have assessed whether family physicians have the proper knowledge of NAFLD and accurate training to diagnose and treat NAFLD/NASH in overweight and obese patients.

METHODS

We conducted an anonymous survey questionnaire. Family Physicians who participated completed 4 years of residency and have passed the final examination. Our survey contained questions to measure the physician's attitudes, source of knowledge and recommendation regarding NAFLD/NASH treatment and attitudes toward patients with NAFLD/NASH. Categorical variables were extracted and analyzed using SPSS.

RESULTS

A total of 310 of 422 FPs were included in the study with a compliance rate of 73%. Our data suggests that 167 of the 310 FPs (55%) refer their patients to a specialist for consultations if they exhibited fatty liver disease. Yet, 284 of 310 send their patients to consolations if exhibiting elevated liver enzyme. Our data significantly suggests that 241 of 310 (78%) reported that they have limited efficacy in treating NAFLD/NASH and consider themselves not properly prepared, by medical schools, to treat NASH/NAFLD patients; as well as patients with obesity and metabolic syndrome without fatty liver.

CONCLUSIONS

FPs are more likely to neglect proper treatment for NAFLD/NASH due to lack of proper knowledge and are more likely neglect referring patients to specialist. Patients with significant obesity and obesity related conditions are more likely to have proactive treatment plans by their FPs.

A Validated Score Assessing the Risk of an Intra-Abdominal Abscess in Patients with Crohn's Disease Presenting at the Emergency Department

BACKGROUND AND AIMS

A majority of acutely ill Crohn's disease [CD] patients who present to Emergency Department [ED] will undergo an abdominal CT to rule out disease complications. We aimed to generate a simple non-invasive scoring model to predict the presence of an intra-abdominal abscess in CD patients in the ED.

METHODS

We performed a retrospective case-control study at four Israeli hospitals from January 1, 2010 to May 30, 2018. Inclusion criteria included patients with an established diagnosis of CD that had cross-sectional abdominal imaging performed. A total of 322 patients were included, and 81 [25%] were diagnosed with an intra-abdominal abscess.

RESULTS

In univariate analysis, ileo-colonic location (odds ratio [OR] 1.88, p = 0.0148), perianal CD [OR 7.01, p = 0.0004], fever [OR 1.88, p = 0.0247], neutrophil-to-lymphocyte ratio [OR 1.12, p < 0.0001], and C-reactive protein [OR 1.10, p < 0.0001] were significantly associated with abscess formation, whereas current use of corticosteroids was negatively associated with abscess formation [OR 0.46, 95% CI, 0.2-0.88, p = 0.0192]. We developed a diagnostic score that included five parameters that were significant on multivariate regression analysis, with assignment of weights for each variable according to the coefficient estimate. A low cut-off score of ≤7 was associated with a negative predictive value [NPV] of 93% for abscess formation, whereas a high cut-off score of >9 was associated with a positive predictive value of 65%. We validated this score with an independent cohort [area under the curve of 0.881 and NPV of 98.5%].

CONCLUSION

We recommend incorporating this score as an aid for stratifying acutely ill CD patients in the ED with low or high probability of the presence of an intra-abdominal abscess.

IgG4 Related Autoimmune Pancreatitis: An Overview and the Emerging Role of Serum Eotaxin as a Potential Treatment Target

Autoimmune pancreatitis (AIP) is a rare disease that has been classified into two subtypes. Type 1 is believed to be mediated by immunoglobulin G4 (IgG4) and type 2 is related to granulocytic epithelial lesions, but the pathogenetic mechanisms in both are still unknown. The patho-mechanism of AIP type 1 is suggested to be secondary to autoimmunity or allergy due to the increased serum IgG4 and immunoglobulin E levels, abundant infiltration of IgG4, plasmacytes and lymphocytes in the pancreas, and fibrosis. Both types of AIP respond to steroid treatment. The relapse rate after remission is high and reaches 30-50% within 6-12 months in AIP type 1; however, in AIP type 2 relapse is rare. The maintenance therapy and therapeutic strategy for relapsing patients with type 1 is managed with low dose steroids, however there are no consensus guidelines. In this review we discuss the current understanding of AIP, highlighting the emerging potential role of eotaxin in pathogenesis, classification, and management of the disease.

Robotic correction of iatrogenic ureteral stricture: preliminary experience from a tertiary referral centre

Objective: Iatrogenic stenosis is a relatively common complication and it could happen after urological procedures in the entire course of the ureter. The aim of this study is to report the surgical outcomes of 36 consecutive patients (period April 2013-November 2018) submitted to robot-assisted correction of benign stricture with previous urological surgery in a tertiary referral center.Methods: Elective criteria were to have had a benign ureteral stricture development after at least one urological procedure. Patients were classified as failures in the event of post-operative ultrasound demonstrating persistent hydronephrosis with or without symptoms or persistent symptoms with renal scan evidence of obstruction or redo procedures.Results: Eighteen patients (50%) were treated for calculosis, seven (19.4%) patients were submitted to double J ureteral stenting and previous pyeloplasty was performed in 11 (30.5%) patients. Overall median operative time was 160 min (IQR = 120-180). Five (13.8%) complications with three (8.3%) surgical post-operative complications occurred. Length of stay was 6 (IQR = 5-7) days. At last follow-up, ranging between 7-60 months, the overall success rate was 86.1% (31/36): three of them (8.3%) were submitted to retrograde holmium laser endopyelotomy, while two (5.5%) underwent a redo robot-assisted correction.Conclusions: Robot-assisted correction procedures can be done safely with good perioperative outcomes and a high post-operative success rate in a tertiary referral center. Further randomized clinical trials are mandatory to confirm the safety of this procedure.

Predictors and colonoscopy outcomes of inadequate bowel cleansing: a 10-year experience in 28,725 patients

Background:

Inadequate bowel preparation is still the main obstacle to a complete colonoscopy in many patients and necessitates many repeated procedures. We aimed to identify risk factors associated with inadequate bowel preparation and to better characterize these patients.

Methods:

This was a retrospective study that reviewed electronic reports of colonoscopy procedures over a 10-year period. Patients were divided into 2 groups: adequate vs. non-adequate bowel preparation. A multivariate analysis was performed to identify variables associated with inadequate bowel preparation, including age, sex, setting (inpatient/outpatient), preparation regimen and procedures’ indications. We examined the effect of inadequate preparation on colonoscopy quality indicators.

Results:

Of the 28,725 patients included in the study, 6,702 (23.3%) had inadequate bowel preparation. In the multivariate analysis, advanced age (odds ratio [OR] 1.015, 95% confidence interval [CI] 1.013-1.017; P<0.01), male sex (OR 1.353, 95%CI 1.286-1.423; P<0.01) and a minority population (OR 1.635, 95%CI 1.531-1.746; P<0.01) were significantly associated with inadequate bowel preparation. The inpatient setting was among the most prominent factors associated with inadequate bowel preparation (OR 2.018, 95%CI 1.884-2.163; P<0.01). Adequate bowel preparation was associated with a higher polyp detection rate (26.8% vs. 23.6%; OR 1.22, 95%CI 1.109-1.347; P<0.01) and colorectal cancer (2.8% vs. 2.4%; OR 1.402, 95%CI 1.146-1.716; P<0.01), and higher frequencies of cecal (96.4% vs. 73.5%; OR 2.243, 95%CI 2.095-2.403; P<0.01) and terminal ileum intubation (8.1% vs. 5.4%; OR 1.243, 95%CI 1.088-1.434; P<0.01).

Conclusion:

We outlined various factors associated with inadequate bowel preparation and confirmed its adverse effect on colonoscopy quality indicators.

Practical clinical approach to the evaluation of hepatobiliary disorders in inflammatory bowel disease

Hepatobiliary disorders are frequent extraintestinal manifestations in inflammatory bowel disease (IBD) and may appear at any time point during the natural course of the disease. Conceptually, these manifestations can be categorised as: (1) disorders that have an association with IBD; (2) diseases directly and structurally related to intestinal inflammation; (3) diseases related to the adverse effects of IBD treatment; and (4) disorders stemming from the metabolic derangements caused by IBD. The clinical presentations of these disorders range from a mild transient elevation of liver enzymes to liver failure and death. Given this wide differential diagnosis and spectrum of severity, it is understandable that the evaluation of patients with IBD with a hepatobiliary abnormality is often challenging. In this review, we present a concise summary of the common hepatic manifestations seen in patients with IBD and focus on the relevant practical issues encountered by gastroenterologists caring for patients with IBD. A practical clinical approach to the evaluation of liver enzyme abnormalities in patients with IBD is provided based on the predominant enzyme elevation pattern (hepatocellular vs cholestatic), before presenting a working scheme for the prevention of hepatitis B virus (HBV) reactivation in patients with IBD receiving immunosuppressive medications. Finally, we specify several laboratory alterations seen in patients with IBD that can potentially interfere with the interpretation of liver function tests, before defining the specific circumstances when a referral for a hepatological consultation is required for further assessment.

Clinical utility of fecal calprotectin: potential applications beyond inflammatory bowel disease for the primary care physician

Fecal calprotectin (FC) is an inflammatory marker released mainly from gastrointestinal granulocytes measured in stool samples. FC is noninvasive, economical, simple, and acceptable for patients. Levels of FC have proven reliable for intestinal inflammation, with good clinical sensitivity, and are useful in screening and monitoring inflammatory bowel disease (IBD), as well as in the differential diagnosis between IBD and irritable bowel syndrome (IBS). Given its advantages, FC represents an attractive biomarker that could be utilized in various gastrointestinal (GI) diseases apart from IBD, and is currently being studied extensively by many research groups with significant amounts of data emerging. In this current review we aim to provide an outline of the utility of FC in distinguishing between IBS and IBD, as well as an up-to-date summary of the available clinical experience concerning FC in various common conditions of the GI tract commonly encountered by gastroenterology practitioners, such as IBS, microscopic colitis, acute gastroenteritis, Clostridium difficile infection, colorectal cancer, diverticular disease, coeliac disease, and other GI conditions.

Endoscopic and Histological Findings among Israeli Populations Infected with Helicobacter pylori: Does Ethnicity Matter?

BACKGROUND

The prevalence of Helicobacter pylori varies geographically by age, race, and socioeconomic status (SES). However, the impact of ethnicity on endoscopic outcomes in infected individuals is not well known.

OBJECTIVES

To assess the impact of ethnicity among Israelis with biopsy-proven H. pylori infection.

METHODS

A retrospective study, including patients who underwent gastroscopy and were diagnosed histologically with H. pylori infection, was conducted. Information on demographics, SES, medications, and co-morbidities were extracted from medical records. Univariate (Student's t-test, chi-square test) and multivariate (multinomial and logistic) regression analysis were conducted to examine the predictors of the clinical outcome.

RESULTS

The study included 100 Israeli Jews and 100 Israeli Arabs diagnosed with biopsy-proven H. pylori infection. At univariate analysis, the number of households was higher among Arabs (P < 0.001), whose family income and parental education were lower than among Jews (P < 0.001 for both variables). The response to amoxicillin and clarithromycin differed between the two groups, being higher among Jews (P < 0.001).In clinical outcomes (gastritis severity, gastric and duodenal ulcer, intestinal metaplasia, atrophic gastritis, and MALT), no statistically significant differences could be detected between Jews and Arabs. Concerning intestinal metaplasia, lack of consumption of nonsteroidal anti-inflammatory drugs resulted a statistically significant protective factor (odds ratio 0.128, 95% confidence interval 0.024-0.685, P = 0.016).

CONCLUSIONS

Although in the literature ethnicity seems to be a risk factor for H. pylori colonization, no statistical significance was detected in various endoscopic and histological findings related to H. Pylori infection between Israeli Arabs and Jews.

Bloating and Abdominal Distension: Clinical Approach and Management

Functional abdominal bloating and distension (FABD) are common gastrointestinal complaints, encountered on a daily basis by gastroenterologists and healthcare providers. Functional abdominal bloating is a subjective sensation that is commonly associated with an objective abdominal distension. FABD may be diagnosed as a single entity (the sole or cardinal complaint) or may overlap with other functional gastrointestinal disorders such as functional constipation, irritable bowel syndrome, and functional dyspepsia. The pathophysiology of FABD is not completely understood. Proposed underlying mechanisms include visceral hypersensitivity, behavioral induced abnormal abdominal wall-phrenic reflexes, the effect of poorly absorbed fermentable carbohydrates, and microbiome alterations. Management includes behavioral therapy, dietary interventions, microbiome modulation, and medical therapy. This review presents the current knowledge on the pathophysiology, evaluation, and management of FABD.

The impact of colonoscopy indication on polyp detection rate

Background

Adenoma/polyp detection rates are considered to be among the most important quality indicators of colonoscopy and are key measures of a quality procedure. However, they are designed for use in the screening setting and are not amenable to other colonoscopy indications. Little is known about their significance in other colonoscopy indications. We aimed to evaluate the impact of the various indications on polyp detection rate (PDR).

Methods

This was a retrospective, single-center study. Electronic reports of index colonoscopy procedures with adequate bowel preparation over a 10-year period were reviewed. Patients were divided into 7 groups based on the study indication. PDR was determined for each group and was compared to that of a control group, the screening indication group. Adjustment was made for potential confounders such as age, sex, and procedural setting.

Results

A total of 13,054 patients were considered suitable for the study. PDR was greatest in the positive fecal occult blood test group, with a value of 33.1% (P<0.01). Overall, the remaining groups showed similar PDRs compared with screening (22.1% vs. 20.4%; P=0.15). This trend persisted in a multivariate analysis, which showed the odds ratio in the positive fecal occult blood test group to be significantly higher, with a value of 1.955 (1.759-2.172, P<0.001) compared with the screening group.

Conclusion

PDR was highest for the positive fecal occult blood test indication, but was not affected significantly by most indications. Further randomized studies are warranted to confirm these findings and help calculate recommended thresholds for "overall" PDR.

Estimation of Gastric Volume Before Anesthesia in Term-Pregnant Women Undergoing Elective Cesarean Section, Compared With Non-pregnant or First-Trimester Women Undergoing Minor Gynecological Surgical Procedures

Background:

Traditionally, intubation of pregnant women has been performed using a rapid sequence induction. This is due to the classical concept that women with more than 18 weeks of pregnancy (mid-second trimester) are always considered to have an increased risk of aspiration due to a number of factors, regardless of the fasting duration. Rapid sequence induction is associated with a higher rate of adverse events.

Aims:

Our study aimed to illuminate the hypothesis that there is no difference in gastric volume between term-pregnant women and non-pregnant or first-trimester pregnant women who were undergoing minor gynecological surgical procedures. Accordingly, we measured gastric volume and content before anesthesia in term-pregnant women undergoing elective cesarean section, and to compare it with non-pregnant or first-trimester pregnant women who were undergoing minor gynecological surgical procedures.

Methods:

In this single-center prospective study, the gastric volume and content were assessed by abdominal ultrasound (AUS) just prior to the scheduled procedure. AUS was performed in the sagittal or para-sagittal plain in the upright position and the stomach content was estimated according to the antral circumferential area. Group 1 consisted of 50 term-pregnant women scheduled for cesarean section. Group 2 consisted of 45 non-pregnant or first-trimester pregnant women who were scheduled for minor gynecologic procedure.

Results:

Despite significant longer fasting time prior to the interventional procedure in the non-pregnant or first-trimester women group, there was no significant difference in gastric volume between term-pregnant and first-trimester pregnant women (3.2 ± 0.97 cm² vs 3.2 ± 0.79 cm²; P = .97). Gastric volume was small in the two groups.

Conclusion:

Fasting gastric volume before cesarean section in term-pregnant women is small and is not different than in non-pregnant or first-trimester women undergoing minor gynecologic procedures. Ultrasound estimation of gastric volume is a reliable and easy-to-perform technique which might help in decision-making regarding the airway management prior to induction of anesthesia in pregnant women.

Propofol sedation in colonoscopy: from satisfied patients to improved quality indicators

Background

Propofol-mediated sedation is safe and clearly associated with increased patient satisfaction. However, whether it results in a favorable effect on colonoscopy outcomes and performance compared to standard sedation with benzodiazepines/opiates remains unclear.

Objectives

To determine the effect of propofol-mediated sedation on colonoscopy-quality measures compared to traditional sedation.

Methods

A large cohort of 44,794 patients who had undergone sedated colonoscopies were included. Colonoscopy-quality indicators were examined in benzodiazepine/opiate-sedated patients and compared with a propofol-mediated sedation group. Adjustment for potential confounders, such as age, sex, quality of bowel preparation, procedural setting, and indication was performed.

Results

Patients who received propofol-mediated sedation were more likely, and in a dose-dependent manner, to have an enhanced polyp-detection rate (22.8% vs 20.9%, P<0.001), cecal intubation rate (90.4% vs 87.3%, P<0.001), and terminal ileum-intubation rate (6.4% vs 1.6%, P<0.001). On multivariate analysis, these findings were maintained, as propofol-mediated sedation use was significantly associated with improved colonoscopy indicators.

Conclusion

Propofol-mediated sedation during colonoscopy is associated with better examination performance and improved outcomes. Further prospective or randomized trials to support these findings are warranted.

Achalasia: Insights into Diagnostic and Therapeutic Advances for an Ancient Disease

Achalasia is a chronic idiopathic disease characterized by the absence of esophageal body peristalsis and by defective lower esophageal sphincter (LES) relaxation. The incidence rate ranges from 1.07 to up to 2.8 new cases per year per 100,000 population. Presenting symptoms include dysphagia, regurgitation, vomiting, and weight loss. The diagnosis of achalasia has undergone a revolution in the last decade due to the advent of high-resolution manometry (HRM) and the consequent development of the Chicago Classification. Recent progress has allowed achalasia to be more precisely diagnosed and to be categorized into three subtypes, based on the prevalent manometric features of the esophageal peristalsis. Treatment options are pharmacotherapy, endoscopic management (Botox injection or pneumatic dilation), and surgery, e.g. laparoscopic Heller myotomy (LHM). More recently, a new endoscopic technique, per oral endoscopic myotomy (POEM), has developed as a less invasive approach alternative to the traditional LHM. Since the first POEM procedure was performed in 2008, increasing evidence is accumulating regarding its efficacy and safety profiles. Currently, POEM is being introduced as a reasonable therapeutic option, though randomized controlled trails are still lacking. The current review sheds light onto the diagnosis and management of achalasia, with special focus on the recent advances of HRM and POEM.

Modular megaprosthesis as definite treatment of femur osteomyelitis

Chronic osteomyelitis represents a challenging to treat clinical entity. A case of a whole femur chronic osteomyelitis, definitely treated with total femur resection and a positioning of a modular megaprosthesis in 2 stages is presented. An 81-year-old female, with hip hemiarthroplasty and internal fixation plate of the distal femur presented with signs and symptoms of femur osteomyelitis. Based on the clinical, radiologic and laboratory findings, the diagnosis of chronic femur osteomyelitis was established. Multiple bone cultures from different femur sites revealed the same methicillin resistant S. aureus. The patient was subjected to a two stage femur reconstruction operation. At the first stage, radical debridement, total femur resection and the application of a custom made vancomycin loaded spacer was performed. After a total of 6 weeks i.v. and 3 months oral proper causative antimicrobial treatment a modular megaprosthesis was applied. The patient was definitely treated from total femur chronic osteomyelitis and has returned to her daily activities. Chronic osteomyelitis demands a multidisciplinary approach, including the right causative long-term antimicrobial treatment, as well as the proper surgical treatment, aiming for eradication of infection and best possible postoperative limb function.

The interplay between abdominal aortic aneurysm, metabolic syndrome and fatty liver disease: a retrospective case-control study

BACKGROUND

Abdominal aortic aneurysm (AAA) and fatty liver disease are both associated with the metabolic syndrome (MS); the aim of this study was to investigate whether patients with AAA are also at a higher risk for fatty liver disease.

METHODS

A case-control retrospective study. Patients diagnosed with AAA were compared with age- and sex-matched controls regarding the prevalence of fatty liver disease. Extracted data include anthropometric parameters, clinical and laboratory data, and liver imaging.

RESULTS

995 patients were enrolled in the final analysis, 495 patients with AAA and 500 age- and sex-matched controls. The prevalence of fatty liver disease among AAA subjects was 48.9% compared with 21.2% among the controls (P<0.005). After adjusting for age, smoking, body mass index, and MS components, the logistic regression analysis indicates that AAA (men: OR 1.29, 95% CI 1.17, 1.49, P=0.001; women: OR 1.23, 95% CI 1.06, 1.43, P=0.002), obesity (men: OR 1.32, 95% CI 1.17, 1.59, P<0.001; women: OR 1.32, 95% CI 1.07, 1.52, P=0.012), hypertension (men: OR 1.23, 95% CI 1.13, 1.46, P=0.001; women: OR 1.13, 95% CI 1.00, 1.33, P=0.045), MS (men: OR 1.31, 95% CI 1.19, 1.53, P=0.001; women: OR 1.28, 95% CI 1.16, 1.42, P=0.002) were associated with non-alcoholic fatty liver disease/non-alcoholic steatohepatitis (NAFLD/NASH). The prevalence of liver cirrhosis was 1.23%; subjects with obesity, diabetes, hypertension, and AAA had increased risk for cirrhosis (OR 1.89, 95% CI 1.18, 3.22, P=0.014; OR 1.27, 95% CI 1.09, 2.72, P=0.0027; OR 2.08, 95% CI 1.29, 3.42, P=0.004; OR 1.73, 95% CI 1.08, 2.87, P=0.027, respectively).

CONCLUSION

AAA patients are at increased risk for NAFLD/NASH, may predict advance liver disease and liver cirrhosis.

Melanosis Coli: A Helpful Contrast Effect or a Harmful Pigmentation?

Background

Melanosis coli, a brown discoloration of colonic mucosa, is considered as a benign condition mainly observed in patients under chronic anthranoid laxatives. Recent data link this condition with an increased adenoma detection rate. Moreover, its tumorigenic potential and possible association with the development of colorectal cancer remains uncertain. We conducted this study to compare the polyp detection rate and colorectal cancer diagnosis in patients with melanosis against matched control group without melanosis.

Patients and methods

A retrospective single-center study. Patients diagnosed with melanosis coli on colonoscopy over a 15-year period were included. Each melanosis coli patient was matched with three controls by age, gender, setting (inpatient/outpatient), and procedure's indication. Polyp detection rate and diagnosis of colorectal cancer were recorded and compared between the groups before and after adjustment for bowel preparation.

Results

A cohort of 718 patients with melanosis and 2154 controls were included. The polyp detection rates were 33.4% and 21.8% of melanosis and control groups, respectively (P < .001). Melanosis coli, however, was associated with less diagnosis of colorectal cancer than controls (0.3% vs 3.9%; P < .001). In multivariate analysis, melanosis diagnosis on endoscopy was significantly associated with higher polyp detection rate (odds ratio [OR] = 1.986, 95% confidence interval [CI]: 1.626-2.425; P value < .01).

Conclusions

Melanosis coli is not associated with increased diagnosis of colorectal cancer. It is associated, however, with enhanced polyp detection likely due to chromo-endoscopy-like effect.

[PRIMARY BILIARY CHOLANGITIS: THERAPEUTIC APPROACH IN THE MODERN ERA]

Primary biliary cholangitis (PBC) is a progressive, autoimmune cholestatic liver disease, predominantly affecting middle-aged women. Hallmark features include a persistent elevation of cholestatic liver enzymes, presence of anti-mitochondrial antibodies and characteristic histologic findings. PBC has a varied course of progression, ranging from mild uncomplicated disease to aggressive disease leading to cirrhosis and resulting in the need for liver transplantation. More than a half of the patients are asymptomatic, but the clinical phenotype varies, and symptoms may be debilitating and have a major impact on quality of life. The goals of PBC management are slowing disease progression, amelioration of associated symptoms and addressing complications of chronic liver disease. The introduction of ursodeoxycholic acid (UDCA) therapy and its universal use as the first-line therapy for PBC has favorably impacted long term prognosis and drastically changed the natural history and disease-related mortality. However, a substantial subpopulation of patients exhibits an incomplete response to UDCA, associated with a sustained disease progression and a poor outcome. Recently, obeticholic acid (OCA) was officially approved as an add-on treatment in patients not responding or intolerant to UDCA. Although evidence for biochemical improvement by OCA is compelling, long-term clinical impact is still under ongoing research. Novel treatment concepts and potential therapeutic options are under investigation. The current review addresses treatment aspects of PBC, while shedding light on the latest updates in patients' management and follow-up.

Associations between sleep duration and sleep debt with insulin sensitivity and insulin secretion in the EGIR-RISC Study

AIM

Extremes in sleep duration play an important role in the development of type 2 diabetes. We examined the associations between sleep duration and sleep debt with estimates of insulin sensitivity and insulin secretion.

METHODS

Data were derived from the European multi-centre EGIR-RISC study. Sleep duration and sleep debt were derived from a sleep questionnaire asking about sleeping time during the week and during the weekend. Insulin sensitivity and insulin secretion were estimated from a 2-hour Oral Glucose Tolerance Test, with samples every 30 minutes. Associations between sleep duration and sleep debt with insulin sensitivity and insulin secretion, were analysed by multiple linear regression models corrected for possible confounders.

RESULTS

Sleep data were available in 1002 participants, 46% men, mean age 48 ± 8 years, who had an average sleep duration of 7 ± 1 hours [range 3-14] and an average sleep debt (absolute difference hours sleep weekend days minus weekdays) of 1 ± 1 hour [range 0-8]. With regard to insulin sensitivity, we observed an inverted U-shaped association between sleep duration and the Stumvoll MCR in (mL/kg/min), with a corrected β (95% CI) of 2.05 (0.8; 3.3) and for the quadratic term -0.2 (-0.3; -0.1). Similarly, a U-shaped association between sleep duration and log HOMA-IR in (µU/mL), with a corrected βs of -0.83 (-1.4; -0.24) and 0.06 (0.02; 0.10) for the quadratic term. Confounders showed an attenuating effect on the associations, while BMI mediated 60 to 91% of the association between sleep duration and insulin sensitivity. No significant associations were observed between sleep duration with insulin secretion or between sleep debt with either insulin sensitivity or insulin secretion.

CONCLUSIONS

Short and long sleep duration are associated with a lower insulin sensitivity, suggesting that sleep plays an important role in insulin resistance and may provide the link with development of type 2 diabetes.

[ACHALASIA: UPDATES ON DIAGNOSIS AND MANAGEMENT FROM THE LAST DECADE]

Achalasia is a rare idiopathic disease, associated with significant morbidity and negative impact on life quality. The disorder is characterized by impairments in the esophageal motility and loss of the lower esophageal sphincter (LES) relaxation. Achalasia symptoms include dysphagia, regurgitations, chest pain, vomiting and weight loss. Diagnosis of achalasia is based on an appropriate clinical presentation and typical findings on complementary tests. These tests include endoscopy showing a dilated esophageal lumen containing fluid or food, High-resolution manometry (HRM) shows evidence of obstruction at the gastro-esophageal junction and motility failure, and barium swallow shows esophageal dilation and distal narrowing. The recent advent of HRM has permitted more precise diagnosis of achalasia and three subtype designations, based on the pattern of esophageal motility disorders, as per the Chicago Classification. Treatment options include: drugs, endoscopic by means of Botox injection or balloon dilation, and the traditional surgery, laparoscopic Heller myotomy (LHM). The new advent in treatment is the novel per-oral endoscopic myotomy (POEM), a less invasive therapy, approaching the traditional LHM. Since the first POEM procedure performed in 2008, massive amounts of evidence are accumulating regarding the high efficacy and safety profiles of POEM, introducing it as an excellent first line treatment. The current review discusses the diagnosis and management of achalasia, with special highlights on the recent progress of HRM and POEM.

Telomere Length, Aggregates, and Capture in Cirrhosis

BACKGROUND

Shortened telomeres were found in patients with cirrhosis, probably reflecting chronic liver injury, continuous regeneration, and destruction of hepatic nodules.

OBJECTIVES

To test whether telomere shortening is a general marker of cirrhosis, independent of disease etiology.

METHODS

We evaluated telomere length in patients with cryptogenic cirrhosis (largely a late sequela of steatohepatitis) compared to patients with cirrhosis caused by chronic hepatitis B and C (HBV/HCV). We also evaluated telomere aggregates, a sensitive parameter of telomere dysfunction and genetic instability. We analyzed peripheral lymphocytes from 25 patients with cryptogenic cirrhosis, 15 patients with cirrhosis due to chronic viral hepatitis, and 20 age-matched controls. Telomere length was analyzed using quantitative fluorescence in situ hybridization. Aggregate size was divided into three fusion groups of 2-5, 6-10, and 11-15 telomeres, relative to the size of a single telomere.

RESULTS

Shorter telomere length was found in patients with cirrhosis from all three etiologies (mean 121.3 ± 24.1) compared to controls (mean 63.5 ± 23.5). In contrast, there was significantly more fusion of > 5 telomeres only in the HBV/HCV cirrhosis group compared to healthy controls (P = 0.023), but not in the cryptogenic cirrhosis group.

CONCLUSIONS

While shortened telomeres in peripheral lymphocytes are a general marker of liver cirrhosis, telomere aggregates may signify a more sensitive genetic instability parameter for the diverse, etiology-based malignant potential of cirrhosis. This finding is in agreement with the well-known higher tendency toward developing hepatocellular carcinoma with cirrhosis caused by chronic hepatitis relative to steatohepatitis.

Inadequate identification of fatty liver disease, obesity, and metabolic syndrome by family physicians

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) is an emerging condition and is constituted as a vital public health epidemic globally. This study evaluated the process of identification and documentation of NAFLD and metabolic syndrome in correlation with those diagnosed with obesity.

METHODS

Participants included 352 patients older than 18 years who were diagnosed with fatty liver disease. We performed a cross-sectional study between August 2016 and September 2017. Categorical variables were extracted and analyzed using SPSS. The body mass index (BMI) was determined by the study staff and compared with the data retrieved from the family physician's database.

RESULTS

Patients who presented documented BMI in their past medical history showed to be significantly higher than those without documentation of BMI (29+4.4 vs 25.7+4.6 kg/m², P<0.01). For instance, 54% of patients with NAFLD were documented in the electronic medical record (EMR) by the family physician, with higher documentation rate among males than females. Moreover, 72% qualified for documentation of metabolic syndrome, but only 5% were documented in their EMR. Patients with significant obesity and obesity-related conditions were more likely to have documentation in their EMR.

DISCUSSION

Further analyses supported the conclusion that family physicians inadequately identify BMI in the EMR for overweight, obesity, metabolic syndrome, and fatty liver disease. Additional efforts are necessary to improve knowledge of proper identification of NAFLD and metabolic syndrome.
