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…
Gegenüberstellung der Wertigkeit von Angioskopie, Angiographie und Sonographie zur Erfassung pathologischer Gefäßwandprozesse
1994
AIMS The ability of angioscopy, angiography and sonography to evaluate arteriosclerotic vascular lesions were compared to determine if angioscopy is a valuable addition in the diagnostic armamentarium. METHODS An in-vitro study was selected to enable microscopic assessment of the arteries. Angiography was followed by sonography and endoscopy and finally the vessels were evaluated macro- and microscopically. RESULTS The configuration of the vascular stenosis (plaque-shape, semicircular-eccentric, circular-concentric) was more reliably defined with angioscopy as compared to angiography and sonography. Intense calcification of plaque was detected sonographically with a high sensitivity (90%) u…

Results of endoscopic retroperitoneal adrenalectomy
1996
Background: From March 1994 to August 1995 we performed extraperitoneal endoscopic adrenalectomy in 18 patients with adrenal gland tumors. Methods: Two of these patients underwent bilateral adrenalectomy. For the extraperitoneal approach a pneumoret-roperitoneum was established and three 10-mm trocars were inserted in the area of the conventional flank incision. Adrenalectomy was performed via these ports. Endoscopic retroperitoneal adrenalectomy was successful in 15 patients; three patients required a conventional operation via an extraperitoneal lumbar approach because of inadequate exposure of the adrenal gland. In patients with endoscopic retroperitoneal adrenalectomy median operative t…
Advanced Endoscopic Imaging Methods
2021
Endoscopic imaging is the mainstay of gastrointestinal endoscopy and has experienced remarkable improvements in recent decades. Further endoscopic innovations stemming from major technological advances such as artificial intelligence and deep learning are at advanced stages of development and will be increasingly deployed in routine clinical practice. These will improve the detection and enable real-time optical diagnosis of pathologies in the gastrointestinal tract. Furthermore, the utilization of endoscopic robots may result in higher diagnostic yield and greater patient comfort. This chapter covers the most recent developments around computer-assisted diagnosis, hypoxia and three-dimensi…
Colonoscopy, Tumors, and Inflammatory Bowel Disease - New Diagnostic Methods
2006
Accurate detection of premalignant lesions and early cancers in the colon is essential for curative endoscopic or surgical therapy, since the prognosis for the affected patients is closely related to the size and stage of the neoplastic lesion. Total colonoscopy is the accepted gold standard for screening and surveillance of colorectal cancer. This review summarizes recently published diagnostic developments and key findings in the areas of colonoscopy, colonic tumors, and inflammatory bowel diseases. Relevant findings have been reported for chromo-endoscopy in the diagnosis of colitis-associated neoplasia, as well as flat and depressed adenomas. Real-time Doppler capabilities have now been…
Endoscopic Management for Patients with Serrated Polyposis Syndrome is Feasible and Effective:
2014
Background and Study Aims: Serrated polyposis syndrome is a rare condition in which multiple serrated lesions develop all over the colon, which is thought to be associated with an increased risk for the development of cancer. The aim of this study was to investigate the feasibility of endoscopic treatment and standardised surveillance in patients with this increasingly recognised syndrome. Methods: From September 2010 to November 2013, consecutive patients were included in a prospective study. All patients underwent chromoendoscopy at first presentation and during surveillance. Follow-up examinations were carried out at 3 month intervals until complete clearance was achieved. Afterwards, pa…

Effects of a low-power He-Ne laser on the healing of experimental colon anastomoses: our experience
1992
Despite technical advances, the incidence of anastomotic leaks in elective colorectal surgery remains around 14%. Recent studies suggest that the use of low-energy lasers may enhance wound healing in different tissues in a selective, nondestructive manner. Based on these findings we have attempted to provide experimental background on the effects of a He-Ne laser during the early stages of healing in 155 colonic anastomoses performed on rats. The irradiation (external or endoscopical) ofthe anastomoses by repeated doses below 4 J/cm 2 suggest (1) the laser-induced enhancement of anastomotic healing can be obtained in both healthy colons or in situations in which anastomotic breakdown is mor…
