BACKGROUND:  Endoscopic resection of ampullary adenomas is a safe and effective alternative to surgical resection. A subgroup of patients have large laterally spreading lesions of the papilla Vateri (LSL-P), which are frequently managed surgically. Data on endoscopic resection of LSL-P are limited and long-term outcomes are unknown. The aim of this study was to compare the outcomes of endoscopic resection of LSL-P with those of standard ampullary adenomas. METHODS:  A retrospective analysis of a prospectively collected and maintained database was conducted...

BACKGROUND:  Sessile serrated polyps (SSPs) are important precursors of colorectal carcinoma and interval cancer. Large SSPs (≥ 20 mm) outside the definition of serrated polyposis syndrome (SPS) have not been studied in comparison with SPS. We aimed to describe the characteristics of patients with large SSPs in this context. METHODS:  Patients with at least one SSP (≥ 20 mm) were eligible. Data from three consecutive colonoscopies were used to compare clinical and endoscopic characteristics in three patient groups: SPS, a solitary large SSP, and patients with at least two SSPs without fulfilling the criteria for SPS (oligo-SSP)...

Three adaptive hypotheses have been forwarded to explain the distinctive Neanderthal face: (i) an improved ability to accommodate high anterior bite forces, (ii) more effective conditioning of cold and/or dry air and, (iii) adaptation to facilitate greater ventilatory demands. We test these hypotheses using three-dimensional models of Neanderthals, modern humans, and a close outgroup ( Homo heidelbergensis ), applying finite-element analysis (FEA) and computational fluid dynamics (CFD). This is the most comprehensive application of either approach applied to date and the first to include both...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) affects > 3 million people in the UK. Acute exacerbations of COPD (AECOPD) are the second most common reason for emergency hospital admission in the UK. Pulmonary rehabilitation is usual care for stable COPD but there is little evidence for early pulmonary rehabilitation (EPR) following AECOPD, either in hospital or immediately post discharge. OBJECTIVE: To assess the feasibility of recruiting patients, collecting data and delivering EPR to patients with AECOPD to evaluate EPR compared with usual care...

BACKGROUND: The SMSA (size, morphology, site, access) polyp scoring system is a method of stratifying the difficulty of polypectomy through assessment of four domains. The aim of this study was to evaluate the ability of SMSA to predict critical outcomes of endoscopic mucosal resection (EMR). METHODS: We retrospectively applied SMSA to a prospectively collected multicenter database of large colonic laterally spreading lesions (LSLs) ≥ 20 mm referred for EMR...

BACKGROUND: Clinical outcomes in acute coronary syndrome patients treated with P2Y12 inhibitors who require urgent coronary artery bypass grafting (CABG) have not been well studied. METHODS: We examined clinical outcomes in acute coronary syndrome patients in relation to the timing of CABG following P2Y12 inhibitor discontinuation (<72 h, 72 h to five days, >5 days). The primary ischemic outcome was a composite of death, reinfarction, need for revascularization, or stroke...

Despite documented benefits, many Total Joint Replacement (TJR) patients find it difficult to access rehabilitation following discharge from hospital. One solution to improve access for TJR patients is telerehabilitation. This study aimed to assess the feasibility of introducing a telerehabilitation program for TJR patients. TJR patients at QEII Jubilee Hospital were invited to complete a questionnaire regarding their access, feelings towards and preferences in using technology. Seventy-five patients were recruited...

BACKGROUND AND STUDY AIMS : Large series suggest endoscopic mucosal resection is safe and effective for the removal of large (≥ 10 mm) sessile serrated polyps (SSPs), but it exposes the patient to the risks of electrocautery, including delayed bleeding. We examined the feasibility and safety of piecemeal cold snare polypectomy (pCSP) for the resection of large SSPs. METHODS:  Sequential large SSPs (10 - 35 mm) without endoscopic evidence of dysplasia referred over 12 months to a tertiary endoscopy center were considered for pCSP...

BACKGROUND: An abdominal aortic aneurysm (AAA) is a focal dilation of the abdominal aorta and is associated with a risk of fatal rupture. Experimental studies suggest that myo-inositol may exert beneficial effects on AAAs through favourable changes to biological pathways implicated in AAA pathology. The aim of the Inositol in the MAnaGemENt of abdominal aortic aneurysm (IMAGEN) trial is to assess if myo-inositol will reduce AAA growth. METHODS/DESIGN: IMAGEN is a multi-centre, prospective, parallel-group, randomised, double-blind, placebo-controlled trial...

BACKGROUND: Women with impalpable or poorly palpable breast cancer require radiologically guided localisation prior to breast conserving surgery. Radioguided Occult Lesion Localisation using Iodine-125 Seed (ROLLIS) is an emerging alternative to conventional Hookwire Localisation (HWL). We compared ROLLIS with conventional HWL with respect to patient reported stress and discomfort related to the localisation procedure. PATIENTS AND METHODS: From September 2013 to January 2016, women who were eligible for breast conserving surgery with impalpable or poorly palpable histologically confirmed invasive or in-situ carcinoma were recruited to the multi-centre ROLLIS randomised controlled trial and underwent either ROLLIS or HWL...

BACKGROUND AND AIMS:  Non-lifting large laterally spreading colorectal lesions (LSLs) are challenging to resect endoscopically and often necessitate surgery. A safe, simple technique to treat non-lifting LSLs endoscopically with robust long-term outcomes has not been described. METHODS:  In this single-center prospective observational study of consecutive patients referred for endoscopic mucosal resection (EMR) of LSLs ≥ 20 mm, LSLs not completely resectable by snare because of non-lifting underwent standardized completion of resection with cold-forceps avulsion and adjuvant snare-tip soft coagulation (CAST)...

OBJECTIVE: To compare the cost-effectiveness of endoscopic submucosal dissection (ESD) and wide-field endoscopic mucosal resection (WF-EMR) for removing large sessile and laterally spreading colorectal lesions (LSLs) >20 mm. DESIGN: An incremental cost-effectiveness analysis using a decision tree model was performed over an 18-month time horizon. The following strategies were compared: WF-EMR, universal ESD (U-ESD) and selective ESD (S-ESD) for lesions highly suspicious for containing submucosal invasive cancer (SMIC), with WF-EMR used for the remainder...

Endoscopic submucosal dissection (ESD) was first conceptually described almost 30 years ago in Japan and is now widely practiced throughout East Asia. ESD expands the boundaries of endoscopic resection (ER) by allowing en bloc resection of large early neoplastic lesions within the gastrointestinal tract (GIT). This offers advantages over other ER techniques by facilitating definitive histological staging and curative treatment of early cancer in selected cases. Indeed the experience of ESD in Eastern countries is significant, and excellent outcomes from high volume centres are reported...

REVIEW

Duodenal adenomas are the most common type of polyp arising from the duodenum. These adenomas can occur within and outside of genetic syndromes, and are broadly classified as non-ampullary or ampullary depending on their location. All adenomas have malignant potential and are therefore appropriately treated by endoscopic resection. However, the unique anatomical properties of the duodenum, namely its relatively thin and vascular walls, narrow luminal diameter and relationship to the ampulla and its associated pancreatic and biliary drainage, pose an increased degree of complexity for any endoscopic interventions in this area...

Post-polymerization modification of the donor-acceptor polymer, poly(9,9-dioctylfluorene-alt-benzothiadiazole), PF8-BT, by electrophilic C-H borylation is a simple method to introduce controllable quantities of near-infrared (near-IR) emitting chromophore units into the backbone of a conjugated polymer. The highly stable borylated unit possesses a significantly lower LUMO energy than the pristine polymer resulting in a reduction in the band gap of the polymer by up to 0.63 eV and a red shift in emission of more than 150 nm...

BACKGROUND AND AIMS: Dysplasia within sessile serrated polyps (SSPs) is difficult to detect and may be mistaken for an adenoma, risking incomplete resection of the background serrated tissue, and is strongly implicated in interval cancer after colonoscopy. The use of endoscopic imaging to detect dysplasia within SSPs has not been systematically studied. METHODS: Consecutively detected SSPs ≥8 mm in size were evaluated by using a standardized imaging protocol at a tertiary-care endoscopy center over 3 years...
