Endoscopic mucosal resection: an evolving therapeutic strategy for non-polypoid colorectal neoplasia
2004
Endoscopic management for laterally spreading tumours of the colorectum is a safe and effective treatment and may be an alternative to surgery in selected patients Colorectal cancer develops in approximately 5–6% of the adult population and is one of the leading causes of cancer death in Europe and the USA.1,2 Screening colonoscopy is the widely accepted gold standard for early diagnosis of colorectal cancer and should be offered to patients older than 50 years.3–5 However, colonoscopy is increasingly in competition with computed tomographic virtual endoscopy.6 Therefore, it is essential to understand whether total colonoscopy rather than virtual endoscopy enables the detection of all relev…
Mesencephalic ependymal cysts: treatment under pure endoscopic or endoscope–assisted keyhole conditions
2008
Object Primary intracranial ependymal cysts are extremely rare. Similar to congenital intraparenchymal cysts in the mesencephalon they usually occur with symptoms of an occlusive hydrocephalus or symptoms like Parinaud syndrome, dizziness, or gait disturbance. The objective of this study was to evaluate the surgical methods for the treatment of these cysts and the clinical outcome of the patients. Methods The authors present the clinical records of 8 patients who were treated in their department for symptomatic mesencephalic ependymal cysts in the past 10 years. The patient age ranged from 22 to 60 years with a mean age of 44 years. In 4 cases the authors performed a suboccipital infratent…
Usage of a semi-rigid intubation endoscope is not superior to a video laryngoscope. A prospective, randomised, controlled trial comparing the SensaSc…
2018
Abstract Introduction Numerous guidelines and techniques have been developed to manage difficult airways and to prevent problems in airway management. To achieve an optimal view of the glottis, various video laryngoscopes and video stylets have been developed and introduced in clinical anaesthesia. The aim of this study was to compare the time to place the tracheal tube (TT) with the McGrath™ Series 5 (McG; Medtronic Dublin, Ireland) and the semi-rigid intubation endoscope SensaScope™ (Sc; Acutronic Medical Systems AG, Hirzel, Switzerland) in elective surgery patients. Methods With the approval of the local ethics committee, patients were recruited for this prospective, randomised clinical …
Disposable chlorine dioxide wipes for high-level disinfection in the ENT department: A systematic review
2020
Abstract Background Nasopharyngoscope reprocessing methods should be effective, rapid and reproducible with moderate cost. Tristel Trio Wipes system (TTWS) is a manual reprocessing method based on chlorine dioxide that has lately emerged in ENT department. This review aims to collect evidence on this system. Methods The PubMed, Web of Science and Cochrane Library databases were searched for all the studies on TTWS or one of its components. Data were grouped according to the study type. Results Ten articles were included in the review. TTWS ensured high-level disinfection in laboratory and clinical setting. Although the limitations of the manual systems, TTWS proved to be faster than automat…
Endoscope-assisted microsurgery for cerebral aneurysms.
1999
A total of 66 patients with intracranial aneurysms were endoscopically assisted treated during a 3 years period. Among those were five individuals with giant aneurysms and 27 patients with aneurysms of the posterior circulation. The endoscope was used only for checking the anatomical structures surround the aneurysms in 16 cases. In 43 patients the aneurysm sac was also dissected under endoscopical con-trol. Even the clipping procedure was performed in seven cases exclusively under endoscopical obser-vation. Only one prematural rupture occurred intraoperatively during preparation of a basilar tip aneurysm. Postoperatively three individuals with aneurysms located in the posterior circulation…
Confocal Laser Endomicroscopy: Technical Advances and Clinical Applications
2010
Since its introduction in 2004, confocal laser endomicroscopy (CLE) has emerged as a valuable tool for gastrointestinal endoscopic imaging. Endomicroscopy enables the endoscopist to obtain real time in vivo histology during ongoing endoscopy thereby creating “optical biopsies.” To date, numerous studies have shown potential applications of endomicroscopy in the clinical setting, including in vivo diagnosis of esophageal squamous cell carcinoma, Barrett’s esophagus, celiac disease, and colonic polyps. Moreover, recent data suggest the potential application of endomicroscopy in the field of molecular imaging. Additionally, in recent months new applications and developments in the field of con…
Direct and oblique approaches to the craniovertebral junction: Nuances of microsurgical and endoscope-assisted techniques along with a review of the …
2017
Purpose: The aim of this review is to provide an update of the technical nuances of microsurgical and endoscopic-assisted approaches to the craniovertebral junction (transnasal, transoral, and transcervical), and to report on the available clinical results in order to identify the best strategy. Methods: A nonsystematic update of the reviews and reporting on the anatomical and clinical results of endoscopic-assisted and microsurgical approaches to the craniovertebral junction (CVJ) was performed. Results: Pure endonasal and cervical endoscopic approaches still have some disadvantages, including their steep learning curves and their deeper surgical fields. Endoscopically assisted transoral s…
Neuroendoscopic Technique for the Operative Treatment of Septated Syringomyelia
1992
The management of septated, chambered syringomyelia has until now been problematic because the usual operative methods cannot secure drainage of all chambers of the cavity.
Endoscope-assisted Craniotomy
1995
We describe a surgical technique to improve visualization of deep brain structures during craniotomy. The technique, developed in a cadaveric model, combines the use of an operating microscope and a solid-rod lens endoscope. Addition of the endoscope during craniotomy allows the operator to visualize structures that otherwise might not have been seen. An approach to the brain stem is demonstrated.
Magnification in apical surgerymusing the endoscope: a review
2011
Objective: A review is made to determine whether the use of the endoscope in endodontic surgery offers advantages in clinical practice, and whether it improves the clinical and radiographic outcomes of the procedure. Material and methods: The main search terms used were: endodontic surgery, apicoectomy, apical surgery, endoscope, and magnification devices . The authors searched the Medline database for articles published up to 1 September 2010. The review included experimental studies comparing endoscopic microstructural findings with the findings of the naked eye or other magnification devices, as well as prospective clinical trials comparing endodontic surgery with or without the use of a…
