Jamshidi needle

Many investigators have reported in the literature on their wide experience concerning outpatient liver biopsy. (22, 35, 36, 43, 49, 70, 76, 88, 106, 167, 174) E. Richter et al. (1972), K. Teubner (1975) and H. Thaler (> 4,000 complication-free outpatient biopsies ) have also reported on this subject. Additional statements have been made by R. Decking (1991) (30), the latter following recommendations issued by the Patient Care Committee (W H. Jacobs et af, 1989). More recent results obtained by A. Giger et al. (1993) (50) and S. Vivas et al. (1998) further advocate this method. The Jamshidi needle also proved to be low in risk. 

Both classical and modified types of biopsy needles are available suction needles (e. g. Menghini, Klatskin, and Jamshidi) and cutting needles (e. g. Vim-Silverman and Tru-cut) as well as spring-loaded needles. (12, 26, 86, 123, 129, 158, 162)... 

A closer look at the publications, however, often reveals that some contraindications and problem situations (e. g. ascites, amyloid degeneration, liver tumours, leukaemia, obstructive jaundice) were not heeded. Likewise, inadequacies in applying the various methods may be responsible for complications. Biopsy needles with a larger diameter of >1.6 mm (e.g. Vim-Silverman, Jamshidi) were also found to involve greater risks.
