REVIEW
Arman Sheybani, Ron C Gaba, R Peter Lokken, Senta M Berggruen, Winnie A Mar
PURPOSE OF REVIEW: This paper reviews diagnostic imaging techniques used to characterize liver masses and the imaging characteristics of the most common liver masses. RECENT FINDINGS: The role of recently adopted ultrasound and magnetic resonance imaging contrast agents will be emphasized. Contrast-enhanced ultrasound is an inexpensive exam which can confirm benignity of certain liver masses without ionizing radiation. Magnetic resonance imaging using hepatocyte-specific gadolinium-based contrast agents can help confirm or narrow the differential diagnosis of liver masses...

PURPOSE OF REVIEW: Locally advanced esophageal cancer is frequently treated preoperatively with chemotherapy and radiation. The degree of response to this preoperative therapy varies in different patients, and a complete pathological response (pCR) has important implications in the management and prognosis of these patients. This is a review of the different modalities currently available to detect pCR and the clinical context of their use. RECENT FINDINGS: While research is still ongoing, no single technique has emerged as the modality of choice to reliably predict pCR in all patients...

REVIEW
Meera Shah, Ryan T Hurt, Manpreet S Mundi
PURPOSE OF REVIEW: The worldwide prevalence of obesity is increasing. Obesity is strongly associated with many chronic health conditions that have been shown to improve with weight loss. However, counseling patients on weight loss can be challenging. Identifying specific aspects of weight management may personalize the conversation about weight loss and better address the individual patient's health goals and perceived barriers to change. RECENT FINDINGS: Physical and behavioral phenotypes are being identified to better tailor treatment recommendations, given lack of efficacy of currently available interventions...

REVIEW
Yeong Yeh Lee, Chandramouli Annamalai, Satish S C Rao
PURPOSE OF REVIEW: Post-infectious irritable bowel syndrome (PI-IBS) is characterized by persistent abdominal pain and diarrhea, typically following an episode of infectious gastroenteritis. The mechanisms that underlie IBS-D remain elusive, but PI-IBS provides a mechanistic model of this disorder. This review provides an up-to-date appraisal of the pathophysiology, clinical features, and management approaches for PI-IBS. RECENT FINDINGS: Disordered immune reactions and release of cytokines with resultant gut inflammation and dysfunction appear to be key features of PI-IBS...

REVIEW
Carolyn Newberry, Lindsay McKnight, Menaka Sarav, Octavia Pickett-Blakely
PURPOSE OF REVIEW: The gluten-free diet (GFD) has become one of the most popular diets in modern history. Claims of improved health and increased energy fuel this popularity, though there is little evidence to substantiate these claims. The present review focuses on outlining known gluten-related disorders (GRD), discussing the GFD in the general population, exploring nutritional considerations, and providing advice for physicians in managing these patients. RECENT FINDINGS: Currently, about a quarter of the population reports keeping a GFD despite GRDs affecting less than half of these individuals...

REVIEW
Eamonn M M Quigley
PURPOSE OF REVIEW: The goal of this review is to review the current status of prokinetics and to place it in historical context. Impaired motility and thus propulsion have long been thought to play important roles in the pathogenesis of a number of gastrointestinal disorders including gastroesophageal reflux disease (GERD), gastroparesis, chronic idiopathic pseudo-obstruction, and constipation. Historically, disordered motility was also thought to contribute to a number of functional gastrointestinal disorders such as functional dyspepsia (FD) and irritable bowel syndrome (IBS)...

REVIEW
C Prakash Gyawali
PURPOSE OF REVIEW: Proton pump inhibitor (PPI) use in gastroesophageal reflux disease (GERD) has been redefined, in light of recent advances highlighting GERD phenotypes that respond to PPIs, and fresh revelations of potential risks of long-term PPI therapy. RECENT FINDINGS: Erosive esophagitis predicts excellent response to PPI therapy, but non-erosive reflux disease (NERD) with abnormal reflux parameters on ambulatory reflux monitoring also demonstrates a similar response...

REVIEW
Nekisa Zakeri, Emmanuel A Tsochatzis
PURPOSE OF REVIEW: Previous perceptions of cirrhosis as a hypocoagulable state have resulted in empirical blood product transfusions prior to invasive procedures. We evaluate procedure-related bleeding risks in patients with cirrhosis, assess the utility of conventional and newer global coagulation tests, and explore evidence surrounding prophylactic transfusion strategies. RECENT FINDINGS: Recent literature supports the concept of a rebalanced, albeit fragile, haemostasis equilibrium in cirrhosis, with a potential hypercoagulable tendency in stable patients...

REVIEW
Jose Ignacio Vargas, Marco Arrese, Vijay H Shah, Juan Pablo Arab
PURPOSE OF REVIEW: The purpose of this study is to analyze the current evidence regarding the use of statins in patients with chronic liver disease and cirrhosis. RECENT FINDINGS: Chronic liver disease (CLD), cirrhosis, and its complications, including hepatocellular carcinoma (HCC), are significant public health problems. The use of statins in patients with CLD has been a matter of concern, and physicians are often reluctant to its prescription in these patients...

REVIEW
John Brooling, Rolando Leal
PURPOSE OF REVIEW: Secondary sclerosing cholangitis is an emerging entity. Yet, because of the low incidence and varying etiologies of this disease, the literature is not robust. There are mainly case reports and small studies evaluating the disease. Our aim in this review is to bring the reader up to date with recent literature on secondary sclerosing cholangitis including the disease presentation, course, prognosis, and treatment options. RECENT FINDINGS: Numerous case reports have been published the last 5 years on secondary sclerosing cholangitis...

REVIEW
Brendon O'Connell, Nazar Hafiz, Seth Crockett
PURPOSE OF REVIEW: In this manuscript, we review current surveillance guidelines for serrated polyps (SPs) and discuss how recent studies inform the selection of appropriate surveillance intervals for patients with SPs. RECENT FINDINGS: Large and/or proximal SPs, particularly sessile serrated polyps (SSPs), are associated with increased risk of both synchronous and metachronous neoplasia, including advanced adenomas and colorectal cancer (CRC). Persons harboring multiple SSPs or dysplastic SSPs are at the highest risk...

REVIEW
Walaa F Abdelmoaty, Lee L Swanstrom
PURPOSE OF REVIEW: We aim to review the endoscopic evaluation of post-fundoplication anatomy and its role in assessment of fundoplication outcomes and in pre-operative planning for reoperation in failed procedures. RECENT FINDINGS: There is no universally accepted system for evaluating post-fundoplication anatomy endoscopically. However, multiple reports described the usefulness of post-operative endoscopy as a quality control measure and in the evaluation of complex cases such as repeat procedures and paraesophageal hernias (PEH)...

REVIEW
William J Ravich
PURPOSE OF REVIEW: This paper presents the author's approach to esophageal dilation. It offers a tailored approach to the application of dilation to specific types of esophageal stenotic lesions. RECENT FINDINGS: In patients with inflammatory stricture, recent studies confirm the importance of treating the underlying inflammatory condition in order to decrease the rate of recurrence. The paper reviews some of the novel techniques that have been suggested for the treatment of refractory benign esophageal strictures, including incisional therapy, stenting, or the injection steroids or antifibrotic agents...

REVIEW
Christopher D Radziwon, Jeffrey M Lackner
PURPOSE OF REVIEW: While dietary and medical treatments are beneficial for specific GI symptoms for some IBS patients, they have an unsatisfactory track record for the full range of GI symptoms for more severe patients. A number of psychological interventions have been developed over the past two decades to help patients' self-manage symptoms. This review discusses the last 5 years of research on psychological treatments, with a focus on cognitive behavioral therapy (CBT) and hypnosis...

REVIEW
Han-Mo Chiu, Wen-Feng Hsu, Li-Chun Chang, Ming-Hsiang Wu
PURPOSE OF REVIEW: Colorectal cancer (CRC) is increasing in Asia, especially in regions with higher levels of economic development. Several Asian countries have launched population CRC screening programs to combat this devastating disease because previous studies have demonstrated that either fecal occult blood test or lower gastrointestinal endoscopy can effectively reduce CRC mortality. RECENT FINDINGS: Screening includes engaging the population, testing, administering a confirmation examination, and treating screening-detected neoplasms; thus, monitoring the whole process using measurable indicators over time is of utmost importance...

PURPOSE OF REVIEW: The discovery of Helicobacter pylori and other organisms colonizing the stomach and the intestines has shed some light on the importance of microbiome in maintaining overall health and developing pathological conditions when alterations in biodiversity are present. The gastric acidity plays a crucial role in filtering out bacteria and preventing development of enteric infections. In this article, we discuss the physiology of gastric acid secretion and bacterial contribution to the composition of gastric and intestinal barriers and review the current literature on the role of proton pump inhibitors (PPIs) in the microbial biodiversity of the gastrointestinal tract...

REVIEW
Sameer K Berry, Corey A Siegel, Gil Y Melmed
PURPOSE OF REVIEW: This article serves as an overview of several quality improvement initiatives in inflammatory bowel disease (IBD). RECENT FINDINGS: IBD is associated with significant variation in care, suggesting poor quality of care. There have been several efforts to improve the quality of care for patients with IBD. Quality improvement (QI) initiatives in IBD are intended to be patient-centric, improve outcomes for individuals and populations, and reduce costs-all consistent with "the triple aim" put forth by the Institute for Healthcare Improvement (IHI)...

REVIEW
Hamish Philpott, Rami Sweis
PURPOSE OF REVIEW: This review aims to discuss the putative relationship between hiatus hernia and dysphagia. RECENT FINDINGS: Proposed mechanisms of dysphagia in patients with hiatus hernia are usually difficult to identify, but recent advances in technology (high-resolution manometry with or without concomitant impedance, ambulatory pH with impedance, videofluoroscopy, and the endoluminal functional lumen imaging probe (EndoFLIP)) and methodology (inclusion of swallows of various consistencies and volumes or shifting position during the manometry protocol) can help induce symptoms and identify the underlying disorder...
