The discussion about laparoscopic appendectomy has increased since the introduction of this method. Randomized comparisons are still feasible, whereas this cannot be stated for other laparoscopic procedures (e.g., laparoscopic cholecystectomy). This randomized controlled trial included 170 patients. Open appendectomy was employed in 83 patients, and 87 were(More)
BACKGROUND It is not clear whether the laparoscopic approach does decrease the incidence of postoperative infectious complications after appendectomy. METHODS One hundred sixty-nine patients were randomized, 87 with laparoscopic (LA) and 82 with open appendectomy (OA). Patients in the OA group had a McBurney incision; LA was performed in the lithotomy(More)
GRUNDLAGEN: Gallengangssteine stellen ein häufiges diagnostisches und therapeutisches Problem im Rahmen der Cholelithiasis dar. Seit Einführung der endoskopischen retrograden Cholangio-Pankreatikographie (ERCP) und Papillotomie (EPT) hat sich das so genannte therapeutische Splitting vor allem nach Etablierung der laparoskopischen Cholezystektomie (LC) als(More)
Since minimally invasive surgery makes high demands on the skill, concentration and endurance of the surgeon, requisite training in this operating technique is of overriding importance. Basic training on pelvitrainers serves to enable the participant to become acquainted with the instruments and the video technique and to gain experience in handling the(More)
In the period November 1991 to October 1993 altogether 418 patients underwent laparoscopic cholecystectomy in our unit. Routine intraoperative cholangiography, a prerequisite for diagnosing choledocholithiasis, was successful in 99.3% of cases. 38 patients were found to have common bile duct calculi and their management and follow up are reported in this(More)
OBJECTIVES We sought to study adenoviral gene delivery using percutaneous selective pressure-regulated retroinfusion and to compare it directly with surgical and percutaneous intramyocardial delivery (PIMD) for the first time. BACKGROUND Intramyocardial delivery (IMD) has been recommended to be the preferred gene delivery strategy so far. However,(More)
The operation simulator with pulsatile organ perfusion ("POP trainer") simulates the blood supply of organs or organ complexes and was developed for the training in both minimally invasive and conventional surgery. With the redesigned new POP-trainer, even complex operations, such as colorectal and antireflux procedures can be practised. Due to perfect(More)
The rapid amplification of indications and areas of application of laparoscopic or thoracoscopic techniques leads to increasing problems and needs in surgical training. Pulsatile perfusion of organs (POP) and organ groups in laparoscopic training devices (pelvitrainers) aids in creating optimum conditions for the simulation of difficult intraoperative(More)
Common bile duct stones may present a health hazard for our patients. Nevertheless, since the implementation of laparoscopic cholecystectomy optimal diagnostic and therapeutic algorithm are not yet defined. Symptomatic calculi can be assumed on the basis of pathological laboratory values or diagnosed by means of ultrasound, Intraoperative Cholangiography(More)
AIMS Percutaneous stent-based ventricle-to-coronary vein bypass (venous VPASS) is a new approach to chronic venous arterialization as a treatment modality in an otherwise no option patient with coronary artery disease. In this study, the efficacy of venous VPASS was compared with catheter-based selective pressure-regulated retro-infusion of arterial blood(More)
