Six hundred fifty-eight intestinal anastomoses in 429 operations for Crohn's disease were studied prospectively during an 8-year period to detect variables connected with perioperative morbidity. Postoperative complications occurred in 9.7% of the patients, 4% had to be reoperated on, and the overall mortality rate was 0.5%. In multivariate analysis by(More)
One carotid from each dog underwent a laser anastomosis and the other carotid an interrupted suture repair. One or eight weeks later (n greater than or equal to 4 dogs/time period); four rings (1 mm in length) containing the laser or suture anastomosis or the normal artery (two/dog) were removed. Using a photoelectric force transducer and lever system, the(More)
From 1989 to 1991, 126 tonsils were prospectively studied in cadavers, volunteers and patients by B-scan ultrasonography. The transducer was positioned just medial of the mandibular angle. The submandibular gland, M. digastricus, M. stylohyoideus and the tongue proved to be suitable landmarks. Normal and chronically inflamed tonsils both presented as oval(More)
During the last three years at the ENT Department of the University of Lübeck, patients with Ménière's disease have been fitted with an endaural catheter. A portable infusion pump with a fluid reservoir then supplied the ear being treated with a continuous gentamicin solution. On average, 3 ml of a 0.3% solution was given each day of treatment. In(More)
Today’s business environment is characterized by complex logistics networks which contain multiple actors participating in the provision of products and services. These (potentially) legally independent yet highly inter-dependent companies need to be coordinated in their actions to achieve a high supply chain performance. Thereby, peculiar challenges –(More)
A comparative study was undertaken to investigate the application of a specially adapted microsurgical Neodymium Yag Laser system with a wavelength of 1,319 μm and a CO2 laser system for laser assisted microvascular end-to-end anastomosis (LAMA) of the rat femoral artery. Conventionally sutured anastomoses served as controls. Postoperative investigations(More)
Two hundred and eight ultrasonographic fine-needle aspiration biopsies were performed in patients with head and neck masses and examined cytologically. The average minimum diameter of the masses was 1.5 cm. The smallest punctured lymph node located in the perivascular sheath had a diameter of 0.4 cm. In none of the patients were complications observed.(More)
