Percutaneous fetal cystoscopy and endoscopic fulguration of posterior urethral valves
Published in American Journal of Obstetrics and Gynecology
Percutaneous fetal cystoscopy was performed in a male fetus with ultrasonographic evidence of lower urinary tract obstruction at 19 weeks of gestation. The diagnosis of posterior urethral valves was confirmed. Percutaneous endoscopic fulguration of the valves was successfully performed at 22 weeks of gestation, and urethral patency was established....
Minimally invasive saphenous vein harvesting: endothelial integrity and early clinical results 1 1 This article has been...
Published in The Annals of Thoracic Surgery
Background. Endoscopic harvesting of vein grafts may reduce wound complications but the effect on the venous endothelium is unknown. Endothelium-derived vasoactive substances may be important in vein graft disease prevention. We investigated the impact of endoscopic harvesting on the release of these factors and proceeded to evaluate the clinical a...
Minimally invasive needlescopic cholecystectomy
Published in Surgery Today
We utilized a mini-sized grasper and retractor measuring 2.5 mm in diameter and a new mini-sized laparoscope measuring 3 mm in diameter to perform a laparoscopic cholecystectomy. A 10/12-mm trocar was inserted as the first trocar for the laparoscope and specimen extraction. Under a direct laparoscopic view, the mini-sized grasper and retractor were...
Minimal invasive Mitralklappenchirurgie
Published in Acta chirurgica Austriaca
Grundlagen: Ziel der Studie war die Durchführung videoassistierter minimal invasiver Eingriffe an der Mitralklappe mit dem Port-Access-System über eine rechtslaterale Minithorakotomie. Alternative Operationsverfahren werden diskutiert. Methodik: Das Port-Access-System ermöglicht über einen in die Aorta ascendens vorgeschobenen Katheter ein endolumi...
Basic knowledge of a microwave tissue coagulator and its clinical applications
Published in Journal of Hepato-Biliary-Pancreatic Surgery
A microwave tissue coagulator originally developed to control hemorrhage during hepatic resection has recently found widespread use in the field of minimally invasive surgery. This surgical tool is based on the principle that by radiating a 2450-MHz (12-cm wavelength) microwave from a monopolar antenna within tissue, the heat generated will be limi...
Minimally Invasive Surgery Induces Endotoxin-Tolerance in the Absence of Detectable Endotoxemia
Published in Journal of Clinical Immunology
Lipopolysaccharide (LPS) tolerance is characterized by an impaired proinflammatory cytokine production upon restimulation of mononuclear cells with LPS. LPS is considered the primary activator for this phenomenon. In response to major injury and extensive abdominal surgery, an immune reaction comparable to LPS tolerance has been described. Therefor...
Comparison of thoracoscopic and laparoscopic heller myotomy for achalasia
Published in Journal of Gastrointestinal Surgery
For more than three decades experts have debated the relative merits of thoracoscopic Heller myotomy (no antireflux procedure) vs. laparoscopic Heller myotomy plus Dor fundoplication for treatment of achalasia. The aim of this study was to compare the results of these two methods with respect to (1) relief of dysphagia, (2) incidence of postoperati...
Initial experience with MIDCAB grafting using the gastroepiploic artery
Published in The Annals of Thoracic Surgery
Background. Minimally invasive direct coronary artery bypass grafting with the gastroepiploic artery can be used in primary operations and reoperations to revascularize the inferior or anterior surface of the heart. Methods. Patients who had symptomatic coronary artery disease limited to a single coronary distribution were selected. Coronary target...
