Postmortem evaluation of four randomly selected automated biopsy devices for transthoracic lung biopsy

Abstract

Automated biopsy devices can obtain high quality lung specimens sufficient for definite histopathologic diagnosis. However, additional clinical studies on the use of automated biopsy devices for lung biopsy are mandatory.

Comparison of fully automated and semi-automated biopsy needles for lung biopsy under CT fluoroscopic guidance

“…Currently, the automated cutting needle in tissue-core biopsy is considered to be useful for obtaining specimens of lung nodules for histological evaluation [17]. There are numerous automated cutting needles, and comparisons of performance of various automated biopsy needles have been made [12,13,[18][19][20]. Hopper et al [12] evaluated 20 different automated biopsy needles for use in fresh autopsy cases and reported that performance of the semi-automated biopsy needles, including the Temno needle, was worse than that of the fully automated biopsy needles, including the Monopty needle.…”

Transthoracic Ultrasonography-Guided Core Needle Biopsy of Pleural-Based Lung Lesions: Prospective Randomized Comparison Between a Tru-Cut-Type Needle And a Modified Menghini-Type Needle

“…Some studies reported better performances of long-throw TCT needles in liver and kidney biopsies of pigs [35] and cadavers [16], whereas an in vivo comparison between TCT and MMT needle showed similar efficacy in liver biopsy [17]. A postmortem evaluation suggested a better performance of the TCT needle in transthoracic biopsy [15], whereas a study evaluating an automated MMT needle reported an overall accuracy of 90.9 %, but no comparison was done with the TCT needle [36]. To our knowledge, there are no in vivo studies comparing the diagnostic yield of the MMT and TCT needles in transthoracic biopsy.…”

“…Several factors can influence the diagnostic yield of transthoracic biopsy, such as needle size [11], length of the needle path [12], and lesion size [12 -14]. However, the yield of the different types of cutting needles used to perform core biopsy has scarcely been investigated, and mostly in cadavers [15,16]. The various kinds of cutting needles can be divided roughly into two types: the modified Tru-cut-type (TCT) needle, and the modified Menghini-type (MMT) needle.…”

A new core‐biopsy instrument with an end‐cut technique provides prostate biopsies with increased tissue yield

“…A side-notch of the inner needle is filled with tissue and an outer cannula is then immediately fired, and cuts a core biopsy from the tissue in the notch. The technique has been evaluated in several studies covering both the prostate and other organs [7][8][9][10][11]. However, there are two major disadvantages with the side-notch needle.…”

“…Second, the first few millimetres of the needle cuts without being filled with tissue. Several other biopsy instruments have been introduced using essentially the same technique [7][8][9]11,12]. Recently, a new instrument for core biopsies (BioPince, Amedic, Sollentuna, Sweden) has been developed.…”
