Abstract

Objectives

To compare ipsilateral decubitus and prone patient positioning for performing computed tomography guided adrenal biopsy using the requirements for out-of-plane approach (OOP) and the needle insertion time (NIT) as a surrogate for procedure complexity.

Methods

The study included 106 adrenal biopsies performed in 104 patients with lesions measuring ≤4 cm that were divided into two groups: Ipsilateral decubitus (Group I) and prone (Group II) positions. The frequency of use of an OOP biopsy path and the NIT were recorded as well as diagnostic yield, adverse events and transgression of organs to approach the target lesion.

Results

Groups I and II comprised 54 and 50 patients, respectively. The use of the OOP approach was significantly less frequent (P < 0.01) in Group I (n = 4) compared to Group II (n = 38). NIT was statistically shorter (P < 0.01) in Group I (9 min and 43 s) compared to Group II (19 min and 7 s). There were fewer organs traversed in Group I versus Group II. Diagnostic yield and post-biopsy complications were equal in both groups.

Conclusion

Ipsilateral adrenal biopsy approach is a less complex, equally reliable and safe compared to the prone approach based on the less frequent use of the OOP approach and the shorter NIT.

Key Points

Ipsilateral adrenal biopsy decubitus positioning provides a direct, non-transpulmonary path for sampling

Ipsilateral decubitus positioning reduces the need for potentially dangerous out-of-plane approaches (OOP)

Ipsilateral decubitus and prone positioning are equally reliable and safe techniques
