Botulinum toxin to avoid component separation in midline large hernias.
2020
Abstract Background The goal of our study was to compare results in patients with large midline incisional hernia using modified anterior component separation versus preoperative botulinum toxin and following Rives repair, with a focus on surgical site occurrences, possibility of fascial closure, duration of hospital stay, and hernia recurrence rate. Methods From to March 2016 to June 2019, a prospective comparative study was performed in 80 consecutive patients with large midline incisional hernias and hernia transverse diameters between 11 and 17 cm under elective hernia repair at our tertiary center. Two groups were analyzed prospectively: 40 patients with preoperative botulinum toxin ad…
Water Jet Dissection in Neurosurgery: An Update After 208 Procedures With Special Reference to Surgical Technique and Complications
2010
Background Water jet dissection represents a promising technique for precise brain tissue dissection with preservation of blood vessels. In the past, the water jet dissector has been used for various pathologies. A detailed report of the surgical technique is lacking. Objective The authors present their results after 208 procedures with a special focus on surgical technique, intraoperative suitability, advantages, and disadvantages. Methods Between March 1997 and April 2009, 208 patients with various intracranial neurosurgical pathologies were operated on with the water jet dissector. Handling of the device and its usefulness and extent of application were assessed. The pressures encountere…
Iris-fixated toric phakic intraocular lens: Three-year follow-up
2006
Purpose To evaluate the 3-year safety, efficacy, predictability, and stability of iris-fixated toric phakic intraocular lens (pIOL) implantation for the correction of myopia or hyperopia with astigmatism. Setting Department of Ophthalmology, Johannes Gutenberg University, Mainz, and Department of Ophthalmology, University Clinic, Bochum, Germany. Methods A prospective clinical trial of 40 eyes of 23 patients with high ametropia and astigmatism was conducted. Best spectacle-corrected visual acuity (BSCVA), uncorrected visual acuity, refraction, astigmatism, intraocular pressure, slitlamp biomicroscopy, and indirect ophthalmoscopy were measured preoperatively and postoperatively. Results Of t…
Measurement of Cortical Microcirculation During Intracranial Aneurysm Surgery by Combined Laser-Doppler Flowmetry and Photospectrometry
2011
Accidental vessel occlusion is one major risk of intracranial aneurysm surgery potentially causing cerebral ischemia. The intraoperative assessment of cerebral ischemia remains a technological challenge.As a novel approach, cortical tissue integrity was monitored using simultaneous measurements of regional capillary-venous cerebral blood flow (rvCBF), oxygen saturation (Srvo2), and hemoglobin amount (rvHb) during aneurysm surgery.Fifteen patients scheduled for aneurysm surgery of the anterior and posterior circulation were included. A fiber optic probe was placed on the cortex associated with the distal branch of the aneurysmatic vessel. Blinded measurements by combined laser-Doppler flowme…
Long-term manometric study of anal sphincter function after hemorrhoidectomy
2006
BACKGROUND AND AIM: Data on maximum resting pressure (MRP) and maximum squeeze pressure (MSP) changes after hemorrhoidectomy are not univocal and follow-up of patients undergoing surgery is mostly short-lived. The aim of this study was to prospectively examine during 1-year follow-up the long-term manometric results of MRP, MSP, and ultra slow wave activity (USWA) within a set of patients undergoing Milligan-Morgan hemorrhoidectomy as compared to healthy controls. MATERIALS AND METHODS: Twenty patients with hemorrhoids of third and fourth degree were enrolled and anorectal manometry was performed preoperatively, on the 5th day, and after 1, 6, and 12 months after surgery. RESULTS: On the 5t…
Manometric Evaluation of Internal Anal Sphincter after Fissurectomy and Anoplasty for Chronic Anal Fissure: A Prospective Study
2012
Chronic anal fissure (CAF) is a common painful clinical disease and its pathogenesis remains poorly understood. After failure of pharmacological therapy, that is the first-line treatment, surgical sphincterotomy remains the treatment of choice although it is followed by a high rate of anal incontinence resulting from the sphincter damage; therefore, the research of a sphincter-saving surgical option has become an important goal. The aim of this study was to evaluate the manometric modifications and the incidence of anal incontinence after fissurectomy and anoplasty with advancement skin flap in patients affected by CAF with hypertonia of the internal anal sphincter (IAS). Fifteen patients …
Oncologic Long-term Outcome of Elective Nephron-sparing Surgery Versus Radical Nephrectomy in Patients With Renal Cell Carcinoma Stage pT1b or Greate…
2011
Objectives To analyze the oncologic outcome and overall survival (OS) for patients with renal cell carcinoma (RCC) >4 cm undergoing radical nephrectomy (RN) or elective nephron-sparing surgery (NSS) in a matched-pair cohort. Methods From 1988 to 2007, we identified 829 patients in our clinic treated with either RN (n = 641) or open NSS (n = 188) for renal masses >4 cm. After matching the cohort for age, time of surgery, grade, TNM stage, tumor size, and sex and excluding patients with metastases, benign lesions with an imperative indication, and those with missing records, 173 remained for oncologic analysis. OS, cancer-specific survival, and progression-free survival were estimated using t…
Acute Aortic Dissection Type A : Age-related Management and Outcomes Reported in the German Registry for Acute Aortic Dissection Type A (GERAADA) of …
2013
To determine the association between age and clinical presentation, management and surgical outcomes in a large contemporary, prospective cohort of patients with acute aortic dissection type A (AADA).AADA is one of the most life-threatening cardiovascular diseases, and delayed surgery or overly conservative management can result in sudden death.The perioperative and intraoperative conditions of 2137 patients prospectively reported to the multicenter German Registry for Acute Aortic Dissection Type A were analyzed.Of all patients with AADA, 640 (30%) were 70 years or older and 160 patients (7%) were younger than 40 years. The probability of aortic dissection extension to the supra-aortic ves…
Magnetic Resonance Imaging Surveillance for Vestibular Schwannoma After Microsurgical Resection Using a Retrosigmoid Transmeatal Approach.
2020
BACKGROUND Vestibular schwannoma (VS) is a benign, usually slow-growing tumor. The drawback of radical microsurgical VS resection is the increased likelihood of neurologic injury, forcing surgeons to leave a tumor remnant in some cases. We evaluated the prognostic value of magnetic resonance imaging (MRI) enhancement patterns to determine the risk of tumor regrowth. METHODS This clinical study included 30 patients (20 women and 10 men) with VS who underwent surgery via a retrosigmoid transmeatal approach. The extent of resection was assessed by MRI 6 months after surgery. Two subtypes of intracanalicular linear enhancement were defined: linear enhancement of the walls of the internal audito…
Emergency toe-to-hand transfer for post-traumatic finger reconstruction: A multicenter case series
2019
Abstract Background The aim of this paper was to evaluate the outcomes of a homogenous series of emergency with a toe-to-hand transfer reconstructions with a different timing: immediate (same surgical step with the debridement), primary (in the first 24 h), early (24–72 h after the debridement) or delayed (72 h-7 days). Materials and methods Between 2001 and 2011, 31 patients received an immediate reconstruction with a toe-to-hand transfer. Data on indications, timing, type of surgery, complications and outcomes (sensory and motor recovery, patient satisfaction) were extrapolated and recorded. Results Most of the procedures in our series (71%) were performed in the first 24 h. Survival rate…
