Local excision for more advanced rectal tumors
2008
Over the past 20 years, local excision (LE) of T1 rectal cancer was increasingly established and represents an oncologically established technique. In contrast, the situation for T2 tumors is less clear and has only been investigated in small patient collectives. LE for T2 tumors is thus discussed controversially.In addition to our own patients with T2 rectal cancer treated locally (n=40), we have analysed the local recurrence (LR) rates after LE alone (n=124), after immediate conventional radical reoperation (n=29), after adjuvant (chemo)-radiotherapy (n=294) and those after neoadjuvant chemoradiotherapy (nCRT) (n=269) using a PubMed search.LR rates of low-grade T2 tumors after R0 resectio…
Prophylactic chimera anterolateral thigh/vastus lateralis flap: preventing complications in high-risk head and neck reconstruction
2014
Purpose In high-risk head and neck cases treated with tumor resection and associated radical neck dissection, orocutaneous fistulas and wound breakdowns in the neck are relatively frequent and can have serious consequences, such as carotid blowout syndrome (CBS), the need for salvage reoperations, and prolonged recovery time. The authors present the application of a prophylactic chimeric anterolateral thigh (ALT) and vastus lateralis (VL) flap to prevent complications. Materials and Methods A retrospective review was performed of a historical group (96 patients) of patients with head and neck cancer treated with tumor resection, radical neck dissection, and microsurgical reconstruction of t…
Clinical analysis following lumbar interspinous devices implant: where we are and where we go
2014
Objectives:We present our experience with patients treated with interspinous devices who are affected by neurogenic intermittent claudication (NIC) or lumbar disc herniation (LDH) where the interspinous system has been inserted following microdiscectomy.Study design:Retrospective study.Methods:This study included patients (n=100) with NIC secondary to lumbar spinal stenosis (group 1), and patients (n=100) with LDH (group 2) in whom the interspinous device has been implanted following radicular decompression in a period spanning 6 years. The latter have been compared with a homogenous group of patients (n=100) where no interspinous system has been implanted following microdiscectomy (group 3…

Prevention of ventricular catheter obstruction and slit ventricle syndrome by the prophylactic use of the Integra antisiphon device in shunt therapy …
2010
Object This 25-year follow-up study was performed on 120 children with hypertensive hydrocephalus to evaluate the influence of the early prophylactic implantation of the Integra antisiphon device (ASD, Integra Neurosciences Ltd.) on the rate of proximal shunt obstructions and the frequency of symptomatic slit ventricle syndrome (SVS). The adaptability of the ASD to growth, proper positioning of the ASD as a necessity for its successful performance, and the 3 phases of SVS development are discussed. Method Since 1978, the ASD has consistently been implanted either at the time of primary shunt insertion (66 neonates, mean follow-up 11 years) or during revisions of preexisting shunts (54 chil…
[Myringoplasties. A retrospective analysis of our surgical outcomes].
2010
Objective: The aim of this study was to present myringoplasty case results in our department. Different factors were studied to confirm their prognostic value. Materials and methods: A total of 126 myringoplasties from 2006 until 2010 were reviewed, collecting patient-related details, descriptions of the anatomical defect and the most interesting surgical aspects. Results: Subtotal perforations (35.7%) were the most frequently observed. In 89.7% of the operations, the transcanal approach was preferred. The medial technique (underlay) to the tympanic membrane was the most performed (97.6%). Cartilage was the principal graft used (82.5%). Complete closure of the perforation was obtained in 71…
The Penile Plication Procedure: An Alternative Method for Straightening Penile Deviation
1991
AbstractThe number of reported cases of congenital and acquired penile deviation is evidently increasing. We describe our experience with the penile plication procedure, which we used to treat 40 patients with penile deviation. Postoperatively, all patients regained the ability for sexual intercourse, with potency remaining unimpaired. Of the patients 96% were completely satisfied with the result of the operation. Sustained complications have not been observed. To avoid major trauma the surgical intervention should not include removal of ellipsoids from the penile tunica albuginea as proposed by Nesbit. Since the penile plication method produces equally good results in terms of performance …
Urinary diversion in children and young adults using the Mainz Pouch I technique
1997
Objectives To determine the late complications and consequences for renal function, vitamin and acid-base metabolism after application of the Mainz Pouch I (MZP-I) technique in children and young adults. Patients and methods To November 1994, the MZP-I procedure was carried out in 463 patients at our institution, 91 of whom were children and adolescents (≤20 years old) using bladder augmentation in 21 and a continent cutaneous stoma in 70. A minimum follow-up of 1 year was possible in 87 patients or 163 renal units (RUs) with a mean of 5.5 years (range 1–10.5). Results At the last examination, 23 of 55 (42%) pre-operatively dilated RUs had improved, 131 of the 163 RUs (80%) were stable and …
Characterization of the effect of intracorneal ring segment in corneal ectasia after laser refractive surgery
2018
Purpose: To evaluate the visual, refractive, topographic, pachymetric, and biomechanical outcomes after intracorneal ring segment implantation in corneas with post-LASIK ectasia. Methods: Retrospective longitudinal study enrolling 26 eyes of 22 patients with post-LASIK ectasia and undergoing intracorneal ring segment implantation (KeraRing®, Mediphacos) using a 60-kHz femtosecond laser (IntraLase®, IntraLase Corp.) for corneal tunnelization. Visual, refractive, anterior, and posterior corneal topographic (Pentacam HR, Oculus), pachymetric, and corneal biomechanical changes (Ocular response Analyzer, Reichert) were evaluated during a 12-month follow-up. Vector analysis of astigmatic changes …
Decompression/Stabilization of the Metastatic Spine: Cotrel-Dubousset-Lnstrumentation in 50 Patients Jan
1993
50 patients with metastatic disease of the spine underwent dorsal decompression and stabilization with the Cotrel-Dubousset-Instrumentation from 1987 to 1991. Indications for surgical treatment were neurologic deficit, spinal instability, and/or pain resistant to medical or radiation treatment. No external orthotics were used postoperatively. Pain was relieved dramatically in 45 patients. Among 25 patients suffering from neurologic deficit preoperatively, 13 improved, 15 remained unchanged, whereas 2 developed an incomplete, transient paraplegia. 15 (7) patients were alive after 1 (2) years. Postoperative complications were frequent, but there were only 2 failures of the stabilization devic…
