“…This task becomes progressively more challenging at steeper needle insertion angles [3][4][5][6][7][8][9][10][11] . This problem is not new and has been the motivation behind a significant body of research in interventional radiology over the last two decades 4,5,[9][10][11][12][13][14][15][16][17][18][19] . Technologies to increase ultrasound visibility have been investigated, with echogenic needle designs proving to be one of the more successful areas of research 4,10,12,18,19 .…”

We assessed whether echogenic needles reduce tip location error, by comparing three echogenic designs (Pajunk Sonoplex, Lifetech, B. Braun Stimuplex D+) with a non-echogenic control (Pajunk Uniplex), using a novel assessment technique in unembalmed human cadavers. Multiple images were taken of each needle at shallow (15 to 25°), moderate (35 to 45°) and steep (55 to 65°) insertion angles. Twenty anaesthetists with varied experience in ultrasound-guided nerve blocks identified needle tip position and stated their confidence level in estimates. Actual tip position was determined at the time of image generation but concealed from the anaesthetists. Two-dimensional mapping of ‘tip-error’ involved measurement of the distance and orientation of each clinician's estimate of tip position in relation to the actual tip position. There were no significant differences in confidence or overall needle visibility at shallow insertion angles. At steeper angles, the Sonoplex showed significantly higher confidence and visibility scores. The remaining echogenic designs did not show any significant differences from the non-echogenic control. Objective measurements of tip error followed the same pattern as the subjective data, although were not universally significant. Two-dimensional mapping showed that as needle visibility deteriorated, so precise tip location was lost but the needle shaft/insertion path remained well-identified. As visibility deteriorated further, accuracy in this axis was also lost. When inaccurate, clinicians generally assessed the needle tip to be more superficial and inserted less far than it actually was. This has important implications for the safety of ultrasound-guided regional anaesthesia. Effective echogenic needle technology has the potential to address these concerns.

“…Reported methods include roughening the inner or outer surface of the needle with a sterile ampoule file or wire, 9 roughening the surface of an inserted stylet, coating the needle with Teflon (DuPont, Wilmington, DE) or polymer, 8 retracting the stylet a few millimeters from the tip, and fast in-and-out movement (jiggling) of the needle. 10 Roughening equipment used for regional block may promote nerve injury from the altered needle surface. Staccato movement of the needle may increase the risk of nerve impalement and puncture of vessels.…”

The results of our in-vitro study suggest a number of factors enhancing ultrasound visibility of regional block needles. The use of needles in the largest possible size inserted with a medium-size guide wire provides the best ultrasound visibility. Analysis of the approach angle favors needle insertion parallel to the transducer. The consideration of these factors may improve safety and success of ultrasound-guided regional blocks.

“…To avoid bleeding as a complication, color Doppler US can be used to identify the major vessels around the large abdominal organs and to plan the biopsy track away from them. 23 In this study, the CNB and FNAB procedures were performed under Doppler US guidance. A safe needle track was determined before starting the biopsy procedure.…”

In this study, it was aimed to contribute to the selection of the method to perform pancreatic lesion biopsies.Data of patients, who had undergone a percutaneous biopsy because of pancreatic masses in our institution in the period between January 2015 and November 2019, were evaluated retrospectively. The percutaneous biopsy method, the type of needle used in the procedure, and periprocedural complications were listed. Pathology and cytology reports in the archive were reviewed, and biopsy results were divided into 3 groups as benign, malignant, and inadequate. Of 308 patients included in the study, the diagnostic accuracy was verified in 124 patients through the assessment of surgical outcomes, results of biopsies from metastatic lesions, or follow-up findings. The verified results were classified as true-positives and true-negatives.Of a total of 308 patients included in the study, 23 underwent a fine-needle aspiration biopsy (FNAB) and 285 underwent a core needle biopsy (CNB). No statistical differences were observed in sample acquisition success and complications between the groups.Of the lesions with a confirmed pathological diagnosis, 67.74% were malignant and 32.26% were benign. The diagnosis was correct in 107 of 112 CNB patients (95.54%) and 9 of 12 FNAB patients (75.00%). When the success of the 2 methods was compared, it was found that outcomes of CNB were statistically more successful compared with those of FNAB.A transabdominal ultrasound-guided percutaneous CNB is a safe method with a high diagnostic yield to perform a biopsy of the pancreas.
