- The aim of this study was to evaluate the axial and radial distribution of histological markers including hyperplasia of the basal cell layer, elongation of the papillae and dilatation of the intercellular spaces of the squamous epithelium in patients with nonerosive reflux disease compared to controls and to relate this to the macroscopic topography in erosive reflux disease. Two different study populations were included in this report. Endoscopic esophageal biopsies were taken from 21 healthy control subjects and 21 nonerosive reflux disease patients before and after 4 weeks of esomeprazole therapy. Endoscopic still images from 50 erosive reflux disease patients were reviewed for the radial orientation of LA grade A and/or B esophagitis (Los Angeles criteria for grading of reflux esophagitis). The 3 o'clock position of the squamocolumnar junction showed significantly thicker basal cell layer (P=0.011) and more intercellular space dilatation (P=0.01) in nonerosive reflux disease patients compared to the 9 o'clock position. Only a significant difference in dilatation of the intercellular spaces (P=0.018) between nonerosive reflux disease patients and controls were observed in the 3 o'clock region at the squamocolumnar junction, whereas 1-2 cm orally, all three histological criteria differed significantly (P

- BACKGROUND AND STUDY AIMS: This study tested the diagnostic value of high-resolution endoscopy for the recognition of subtle diagnostic esophageal mucosal changes in nonerosive reflux disease. PATIENTS AND METHODS: Ten control subjects and eleven patients with nonerosive reflux disease confirmed by a validated questionnaire, standard endoscopy, and 24-hour pH-metry participated in the study. Still images were collected by high-resolution endoscopes from the distal esophagus in a standardized manner, incorporating iodine staining. Assessments were repeated in the patients with reflux disease after 4 weeks of esomeprazole therapy. Interobserver variability in the recognition of the proposed criteria was initially evaluated by 27 endoscopists using an Internet-based process. After optimisation of image quality the evaluation was repeated face-to-face with six expert endoscopists. RESULTS: No criterion was identified in either assessment that was sufficiently sensitive and specific to patients with reflux disease to be clinically useful. The kappa value, used to assess interobserver variation, was acceptably high only for invisibility of palisade vessels (0.59). Triangular indentations, apical mucosal breaks, and pinpoint blood vessels at the squamocolumnar junction were identified more frequently in the patients with reflux disease ( P < 0.05). These changes and the invisibility of the palisade vessels were significantly less prevalent in reflux patients after therapy ( P < 0.01). CONCLUSIONS: Though some distal esophageal mucosal appearances observed with the high-resolution endoscope appeared to be related to nonerosive esophageal mucosal injury, none of these changes proved to be sufficiently sensitive and specific to justify their use as a diagnostic criterion for nonerosive reflux disease.

- OBJECTIVE: To assess the value of arterial duplex ultrasound, which assesses the location and severity of arterial disease, in determining whether invasive vascular intervention is required.METHOD: A total of 166 consecutive diabetic patients presenting at a multidisciplinary foot clinic with severe peripheral vascular disease, with or without a foot ulcer, were included in this prospective study. The choice of vascular intervention was based on the results of a duplex ultrasound examination. Subjects were followed up for two years, and their clinical management, vascular assessments and interventions given, and patient outcomes were recorded in a specially designed protocol.RESULTS: Based on findings of the duplex ultrasound, it was recommended that 55 patients (33%) should undergo angioplasty (percutaneous transluminal angioplasty [PTA] and/or subintimal recanalisation), 64 patients (39%) diagnostic angiography and 47 patients (28%) medical treatment only, thereby avoiding unnecessary angiography and its potential complications. Diagnostic angiography was recommended when the duplex ultrasound results were inconclusive. Fifty-two of the 55 patients recommended angiography with simultaneous angioplasty had an angiography; of these, 42 (81%) then had an angioplasty. Fifty-seven of the 64 patients with inconclusive results had an angiography. Of these, 23 (40%) subsequently had angioplasty, only 10 (18%) had reconstructive surgery and 24 (42%) had a diagnostic angiography only.CONCLUSION: Arterial duplex ultrasound may assist evaluations of the need for and type of invasive vascular intervention in patients with an ischaemic diabetic foot. It can thus help avoid diagnostic angiographies that do not result in vascular intervention. However, such decision-making remains at the discretion of the vascular surgeon and radiologist.
