Simple endoscopic decompression of cubital tunnel syndrome with the Agee system: anatomic study and first clinical results.
2010
BACKGROUND Simple decompression in ulnar nerve compression syndromes offers options for endoscopic applications. OBJECTIVE The authors present their initial experience with the Agee device. PATIENTS AND METHODS The monoportal endoscopic technique (Agee system) was evaluated on 10 cadaveric arms. Subsequently, 32 arms of 29 patients were operated on between January 2006 and March 2009. All patients presented with typical clinical signs and neurophysiologic studies. Long-term follow-up examinations were obtained in 27 of 32 arms. RESULTS In the cadaver study, the ulnar nerve was always correctly identified. No nerve damage occurred, and sufficient decompression of the ulnar nerve was always a…
Prospective Evaluation of Positron Emission Tomography in the Preoperative Staging of Esophageal Carcinoma
2004
Hypothesis Positron emission tomography (PET) is a useful tool in the selection of patients with esophageal cancer who may not benefit from esophageal resection. Design Case series. Setting Tertiary care hospital. Patients Eighty-one patients with newly diagnosed esophageal cancer who underwent PET and computer tomography (CT) of the chest and abdomen (and of the neck in 45 patients) within 45 days were included. Main Outcome Measures We calculated the sensitivity and specificity in detecting metastatic sites on the basis of 31 histologically verified lesions. In addition to results obtained on CT, the information provided by PET was evaluated with a view to the choice of management strateg…
Preoperative endoscopic pyloric balloon dilatation decreases the rate of delayed gastric emptying after Ivor–Lewis esophagectomy
2018
Delayed gastric emptying (DGE) after Ivor-Lewis esophagectomy occurs postoperatively in up to 50% of the patients. This pyloric dysfunction can lead to severe secondary complications postoperatively such as early aspiration, pneumonia or may even have an impact on anastomotic healing and therefore leakage. Early detection of DGE is essential to prevent further complications. The common treatment postoperatively is endoscopic pyloric balloon dilatation (EPBD) after symptoms already occurred. In our work, we analyzed patients who received a preoperative EPBD during the routine restaging endoscopy and compared those patients to a control group to analyze if preoperative EPBD may prevent postop…
Is Routine Preoperative Upper Endoscopy in Gastric Banding Patients Really Necessary?
2006
Background: Preoperative evaluation for bariatric surgery is complex. Our investigation focused on the necessity for upper gastrointestinal (GI) endoscopy as a routine procedure before performing gastric banding. Methods: A consecutive series of 145 patients underwent laparoscopic adjustable gastric banding (LAGB). Gastroscopy was performed routinely before LAGB. All patients were interviewed before gastroscopy regarding gastroesophageal symptoms. Gastroscopic findings and the results of the interview were blinded and set in comparison. Furthermore, we analyzed whether upper GI symptoms, BMI, age or gender were predictive parameters for pathological findings on gastroscopy. Small hiatal her…
Non‐invasive haemoglobin measurement as an index test to detect pre‐operative anaemia in elective surgery patients – a prospective study
2020
Non-invasive haemoglobin measurement using absolute values lacks the precision to be the sole basis for the treatment of pre-operative anaemia. However, it can possibly serve as a screening test, indexing 'anaemia' with high sensitivity when values remain under prespecified cut-off values. Based on previous data, non-invasive haemoglobin cut-off values (146 g.l-1 for women and 152 g.l-1 for men) detect true anaemia with 99% sensitivity. An index test with these prespecified cut-off values was verified by prospective measurement of non-invasive and invasive haemoglobin pre-operatively in elective surgical patients. In 809 patients, this showed an estimated sensitivity (95%CI) of 98.9% (94.1-…
Value of contrast-enhanced MR angiography and helical CT angiography in chronic thromboembolic pulmonary hypertension.
2003
The aim of this study was to evaluate the diagnostic value of contrast-enhanced MR angiography (ce MRA) and helical CT angiography (CTA) of the pulmonary arteries in the preoperative workup of patients with chronic thromboembolic pulmonary hypertension (CTEPH). The ce MRA and CTA studies of 32 patients were included in this retrospective evaluation. Image quality was scored by two independent blinded observers. Data sets were assessed for number of patent segmental, subsegmental arteries, and number of vascular segments with thrombotic wall thickening, intraluminal webs, and abnormal proximal to distal tapering. Image quality for MRA/CTA was scored excellent in 16 of 16, good in 11 of 14, m…
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…
Mono-stereo-autostereo: the evolution of 3-dimensional neurosurgical planning.
2012
BACKGROUND: In the past decade, surgery planning has changed significantly. The main reason is the improvements in computer graphical rendering power and display technology, which turned the plain graphics of the mid-1990s into interactive stereoscopic objects. OBJECTIVE: To report our experiences with 2 virtual reality systems used for planning neurosurgical operations. METHODS: A series of 208 operations were planned with the Dextroscope (Bracco AMT, Singapore) requiring the use of liquid crystal display shutter glasses. The participating neurosurgeons answered a questionnaire after the planning procedure and postoperatively. In a second prospective series of 33 patients, we used an autos…
Assessing preoperative anxiety using a questionnaire and clinical rating
2013
Background Preoperative anxiety and need for information can be detected during preoperative consultation via structured and standardised screening by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaire. Objective To identify the prevalence of preoperative anxiety and need for information, with regard to influencing factors such as age, sex, previous operation and grade of surgery, and to examine the level of agreement between patients' self-rating and physicians' ratings. Design Prospective observational study. Setting Department of Anaesthesiology, University Medical Centre of the Johannes Gutenberg University Mainz, Germany. Patients Two hundred seventeen patie…
Anxiety and subjective quality of life preoperatively and 4 months after reduction mammaplasty.
2005
Abstract Objective The aim of this study was to evaluate the development of anxiety, psychological distress, and subjective quality of life on the basis of the criteria of satisfaction and expectations in a group of women who had undergone reduction mammaplasty for cosmetic reasons. Method The population consisted of 20 women who had requested breast reduction treatment [mean age, 34.70 (±10.94)] for cosmetic reasons. After being informed of the purpose of the study and after giving their written consent, the subjects took part in a psychological examination conducted at two different times (T1, initial medical consultation; T2, 4 months after surgery). At each of these stages, the psycholo…
