CRT-723 Is the Sporadic Thoracic Aortic Aneurysm the Result of an Inflammatory Process?
2014
Sporadic thoracic aortic aneurysm (S-TAA) is potentially devastating with severe morbidity and mortality. The histopathologic underlying abnormality of both ascending aortic aneurysm and dissection is medial degeneration, a pathological entity initially described as no inflammatory lesions of smooth
Technical advances in radical retropubic prostatectomy techniques for avoiding complications. Part I: apical dissection
2003
Radical retropubic prostatectomy is currently the most widely used surgical treatment for localized prostate cancer. This once cumbersome procedure has developed technically over the last 20 years, reducing dramatically the associated complications and morbidity, e.g. blood loss, incontinence and impotence. Currently the operation is safe and is the best choice for eradicating localized disease, with little loss in quality of life. However, differences in reported outcomes indicate that there is still a need for standardization and continued efforts for surgical excellence. This review focuses on the crucial steps of the procedure, in two parts: the first covers apical dissection and the se…
Pulsed radiofrequency energy device (PEAK plasmablade™) and CustomBone® Cranioplasty: an appealing surgical rendez-vous
2019
Background: CustomBone® prosthesis is a widely recognized effective and successful technique for the reconstruction of cranial bone defects. Prior the cranioplasty implant, meticulous dissection wi...
Endoscope-assisted keyhole surgery for aneurysms of the anterior circulation and the basilar apex
2000
In the treatment of cerebral aneurysms, preoperative surgical planning and intraoperative strategies for microsurgical approaches are important issues. Within the context of minimally invasive neurosurgery, so-called keyhole approaches, especially those with intraoperative endoscopic assistance, have gained increasing interest, but their application for cerebral aneurysm surgery is a matter of ongoing controversy. The main aspects of keyhole microsurgery, with and without endoscopic assistance, for cerebral aneurysms are explained. To present the keyhole concept, which is based on the preoperative analysis and intraoperative use of pre-existing anatomic windows, this article concentrates on…
Chimioradiothérapie des cancers de l’œsophage : quelles aires ganglionnaires faut-il irradier ?
2014
Esophageal cancer has a high likelihood of distant lymphatic spread even at an early stage. Radiotherapy plays a major role in the management of localized or locally-advanced esophageal cancer with a regional or distant lymph node involvement. Radiotherapy can sterilize micrometastatic nodes and cancer cells in transit in the peri-esophageal fat that are not removed by surgery. After preoperative chemoradiotherapy followed by monobloc esophagectomy including lymph node dissection above and below the diaphragm, the locoregional failure rate was around 3% in the Chemoradiotherapy for Esophageal Cancer followed by Surgery Study Group (CROSS) trial. This is significantly lower than that observe…
Art und Prognose des lokoregionären Rezidivs beim Rektumkarzinom: Eine Nachsorgestudie
2008
The recurrence rate after 438 curative operations for rectal carcinoma was 44.1% (193 cases). It was independent of age and sex, but correlated closely with tumour stage. Tumours in an early stage recurred rarely and late. The success of a second operation was influenced by the type of local-regional recurrence. Only three of 34 presacral recurrences were again treated surgically with cure as the aim, compared with seven of 17 anastomosis recurrences, five of eight perineal recurrences, four of six recurrences after local dissection, and all colostomy recurrences, vaginal recurrences and metachronic second tumours. The further course demonstrated that about three quarters of patients who ha…
Die Tonsillotomie mit der bipolaren Koagulationsschere
2008
BACKGROUND: Nowadays, tonsillotomy is an accepted operating procedure for the diagnosis of tonsillar hyperplasia in small children. Up to now many different techniques such as laser, radiofrequency, coblation or micro-debrider have been used. In this study, for the first time bipolar coagulation scissors were utilized. METHODS: Up to December 2006, a total of 91 children with benign tonsillar hyperplasia were tonsillotomized by bipolar coagulation scissors. Of these 91 children, 38 (average age 74 months) were recruited for this study. Pre-operative and post-operative complaints were documented and the success of the operation was evaluated by the parents. RESULTS: In more than 90 % of the …
The “Jacobsen Flap” for the Treatment of Stage III–IV Dupuytren’s Disease at Little Finger: Our Review of 123 Cases
2011
For selective fasciectomy in patients with Dupuytren’s disease at Tubiana Stage I–II, midline longitudinal incisions with serial Z-plasties, Bruner zigzag incisions, and V-Y plasties over the palm and most severely affected fingers are accepted methods. Advantages of these approaches are good intraoperative visualization of the fibrous tissue, rapid dissection, minor tissue trauma, and usually the possibility of a tension-free wound closure (Brenner and Rayan 2003). In cases of Dupuytren’s disease at Stage III and IV, with severe digital flexion, inelastic overlying skin, and expected skin shortage after contracture release, these incisions may sometimes be useful, but in our experience, qu…
Phosphodiesterase10A: abundance and circadian regulation in the retina and photoreceptor of the rat.
2011
Phosphodiesterase10A (PDE10A) is a dual specific cyclic nucleotide phosphodiesterase that is specifically enriched in striatum and which has gained attention as a therapeutic target for psychiatric disorders. The present study shows that PDE10A is also highly expressed in retinal neurons including photoreceptors. The levels of PDE10A transcript and protein display daily rhythms which could be seen in preparations of the whole retina. Corresponding changes in PDE10A mRNA were seen in photoreceptors isolated using laser microdissection. This suggests that the expressional control of the photoreceptor Pde10a gene contributes to the observed cyclicity in the amount of retinal PDE10A. The daily …
Indocyanine Green-Enhanced Colorectal Surgery—between Being Superfluous and Being a Game-Changer
2020
Nowadays, surgical innovations incorporate new technological conquests and must be validated by evidence-based medicine. The use of augmented reality-assisted indocyanine green (ICG) fluorescence has generated a myriad of intraoperative applications such as demonstration of key anatomical landmarks, sentinel lymph nodes, and real-time assessment of local blood flow. This paper presents a systematic review of the clinical evidence regarding the applications of ICG near-infrared (NIR) fluorescence in colorectal surgery. After we removed duplicate publications and screened for eligibility, a total of 36 articles were evaluated: 23 on perfusion assessment, 10 on lymph node mapping, and 3 on int…
