OBJECTIVE: To assess the long-term efficacy of antireflux surgery on Barrett's esophagus (BE) using BRAVO wireless pH monitoring. BACKGROUND: BE is associated with chronic gastroesophageal reflux and esophageal cancer. Till date, studies have failed to demonstrate that preventing gastroesophageal reflux with antireflux surgery halts the progression of BE, often because of difficulties in objectively proving an effective antireflux barrier. METHODS: Since 1991, all patients undergoing antireflux surgery across 2 hospital sites have been followed in a prospective database...

Anaplastic thyroid cancer (ATC) is an aggressive uncommon malignancy with limited treatment. Traditional antineoplastic chemotherapy has not been successful in the management of metastatic ATC. As a result, the focus has shifted to the development of novel therapies for this disease. The availability of economical comprehensive genomic profiling (CGP) platforms with rapid turn-around to identify molecular aberrations in tumors that are potential therapeutic targets has increasingly changed the face of cancer therapy...

Esophageal adenocarcinoma is rapidly increasing in incidence in many Western societies, requires demanding treatment and is associated with a poor prognosis, therefore preventive measures are highly warranted. To assess the opportunities for prevention, we reviewed the available literature and identified seven main potentially preventive targets. Preventive effects were found based on medium level observational evidence following treatment of gastroesophageal reflux disease (both using medication and surgery) and tobacco smoking cessation, which should be clinically recommended among exposed patients...

OBJECTIVE: To compare the effect of anti-reflux surgery (ARS) versus proton pump inhibitor therapy on lower oesophageal sphincter (LOS) function and oesophageal acid exposure in patients with chronic gastro-oesophageal reflux disease (GORD) over a decade of follow-up. MATERIAL AND METHODS: In this randomised, prospective, multicentre study we compared LOS pressure profiles, as well as oesophageal exposure to acid, at baseline and at 1 and 10 years after randomisation to either open ARS (n = 137) or long-term treatment with omeprazole (OME) 20-60 mg daily (n = 108)...

Endoscopic therapy of early Barrett's neoplasia is nowadays the treatment of choice and recommended over surgery in most current guidelines. Recent data suggest radiofrequency ablation of low-grade intraepithelial neoplasia when confirmed by an expert pathologist. Endoscopic therapy of high-grade intraepithelial neoplasia and mucosal Barrett's adenocarcinoma consists of two steps: first endoscopic resection of all visible lesions, and second ablation of the remaining flat Barrett's mucosa to reduce the rate of recurrences and metachronous neoplasia...

OBJECTIVE: We examined whether surgically induced membrane defects elevate connexin 43 (Cx43) expression in the wound edge of the amniotic membrane (AM) and drives structural changes in collagen that affects healing after fetoscopic surgery. METHOD: Cell morphology and collagen microstructure was investigated by scanning electron microscopy and second harmonic generation in fetal membranes taken from women who underwent fetal surgery. Immunofluoresence and real-time quantitative polymerase chain reaction was used to examine Cx43 expression in control and wound edge AM...

INTRODUCTION: Barrett's esophagus (BE) is recognized as a premalignant lesion for esophageal adenocarcinoma. BE appears as a consequence of gastroesophageal reflux disease (GERD), which is increased among obese population. Laparoscopic Roux-en-Y gastric bypass (LRYGB) is the best treatment option for obesity combined with GERD. However, data on evolution of BE after LRYGB are scarce. METHODS AND PROCEDURES: Patients were studied with esophagogastroduodenoscopy (EGD) and gastric biopsy preoperatively...

The endoscopic management of Barrett's esophagus (BE) has changed with the emergence of novel endoscopic technologies and new data informing the care of dysplastic BE and early adenocarcinoma. These changes include an expanded use of endoscopic ablative therapy as well new recommendations for surveillance intervals. For most patients with BE and high-grade dysplasia (HGD), endoscopic ablative therapy is the preferred treatment strategy. Ablation has consistently been shown to be effective, with less morbidity compared with surgery...

BACKGROUND: Oesophageal cancer following bariatric surgery adds significant complexity to an already challenging disease. There is limited data on the diagnosis, presentation and management in these complex cases. METHODS: A retrospective cohort study on prospectively collected data over 10 years was conducted. The oesophago-gastric cancer database was searched for patients with prior bariatric surgery. Data were retrieved on bariatric and cancer management. RESULTS: We identified nine patients with oesophageal or gastro-oesophageal junction adenocarcinoma after bariatric surgery...

BACKGROUND: Recent studies suggest that chronic inflammation-associated cancer is relevant to microbiome. Esophageal adenocarcinoma arises from an inflammatory condition called Barrett's esophagus, which is caused by gastroesophageal reflux. We hypothesized that esophageal microbiome plays a role in carcinogenesis of esophageal adenocarcinoma. AIM: We investigated whether alteration of microbiome using antibiotics affects the development of esophageal adenocarcinoma in a rat model...

BACKGROUND: The Orthopedic In-Training Examination is an annual standardized examination with multiple-choice questions focused on application of orthopedic surgery core knowledge and principles. The outcome of this test can be used to both predict how residents are progressing in their orthopedic knowledge as well as assess their likelihood to pass the Orthopedic Board Examinations, that is the American Boards of Orthopedic Surgery Part 1, following completion of residency. Preparation for the examination can be difficult, as residents commonly have limited study time to review the vast amounts of available published literature...

PURPOSE: Preoperative oesophago-gastro-duodenoscopy (p-OGD) is often routinely employed in patients undergoing bariatric surgery. The value of p-OGD is still unclear; however, since all bariatric procedures modify stomach anatomy differently with exclusion of the remnant in a majority of cases, the question arises whether there is a rational for including it routinely in the preoperative pathway. MATERIAL AND METHODS: To assess the current status of p-OGD in the UK, a survey was sent to the British Obesity & Metabolic Surgery Society members, regarding preoperative evaluation of patients, focusing on the role of p-OGD...

PURPOSE: To evaluate the accuracy of the optical coherence tomography-based (OCT formula) and Barrett True K (True K) intraocular lens (IOL) calculation formulas in eyes with previous radial keratotomy (RK). METHODS: In 95 eyes of 65 patients, using the actual refraction following cataract surgery as target refraction, the predicted IOL power for each method was calculated. The IOL prediction error (PE) was obtained by subtracting the predicted IOL power from the implanted IOL power...

The primary purpose of the facelift is to restore the shape, volume, and contours of the youthful face. Facelift surgery has evolved over the years into multiple techniques to accomplish the same results. This article discusses the common controversies in facelift surgery and evaluates the best available evidence to guide surgical decision-making. In regard to the salient question of whether there is a "best" technique, the literature suggests that the options are generally equal in efficacy. This highlights the need for high-quality research with standardized preoperative assessment and evaluation of postoperative results to better assess outcomes...

Exciting new developments-pharmacologic, endoscopic, and surgical-have arisen for the treatment of many esophageal diseases. Refractory gastroesophageal reflux disease presents a therapeutic challenge, and several new options have been proposed to overcome an insufficient effectiveness of proton pump inhibitors. In patients with distal esophageal spasm, drugs and endoscopic treatments are the current mainstays of the therapeutic approach. Treatment with proton pump inhibitors (or antireflux surgery) should be considered in patients with Barrett's esophagus, since a recent meta-analysis demonstrated a 71% reduction in risk of neoplastic progression...

Recent-years technological innovation has achieved two important objectives: 1) to develop advanced diagnostic tools able to determine with a fair degree of accuracy the nature of a lesion by means of the simple endoscopic observation; 2) to improve the therapeutic approach to lesions, by extending the least-invasive endoscopic treatment also to lesions that in the past were referred to surgery. Advanced diagnostic methodologies have been achieved thanks to the introduction of high definition endoscopes and virtual chromo-endoscopy...

In the last few decades, endoscopic treatment of early neoplastic lesions in the esophagus has established itself as a valid and less invasive alternative to surgical resection. Endoscopic resection (ER) is the cornerstone of endoscopic therapy. Next to the curative potential of ER, by removing neoplastic lesions, ER may also serve as a diagnostic tool. The relatively large tissue specimens obtained with ER enable accurate histological staging of a lesion, allowing for optimal decision-making for further patient management...

As an increase in gastroesophageal reflux disease (GERD) has been reported in Japan, and public interest in GERD has been increasing, the Japanese Society of Gastroenterology published the Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009. Six years have passed since its publication, and there have been a large number of reports in Japan concerning the epidemiology, pathophysiology, treatment, and Barrett's esophagus during this period. By incorporating the contents of these reports, the guidelines were completely revised, and a new edition was published in October 2015...
