longbiopsie

Longbiopsie is a term used in some medical literature to describe a biopsy approach in which a relatively long tissue specimen is obtained. The term is not standardized and its exact meaning varies by author and language. In many uses, longbiopsie denotes procedures that prioritize tissue length in addition to diameter, such as using longer core biopsy needles to harvest extended cores, or performing consecutive adjacent biopsies along a lesion to create a longer composite specimen. It can also refer to open or incisional techniques designed to yield a longer piece of tissue.

Applications and rationale: Longer specimens can improve architectural assessment, allow evaluation of tumor margins, and reduce sampling error in heterogeneous lesions. It may be considered when small samples fail to provide sufficient histological context or when immunohistochemical or molecular studies require more material.

Limitations and risks: Longer samples can increase procedural complexity, bleeding risk, and patient discomfort. The approach may not be feasible in anatomically constrained areas, and sampling along a tract raises theoretical risk of tumor seeding, although this is uncommon. The diagnostic yield depends on lesion heterogeneity and the skill of the operator.

Status and terminology: Because longbiopsie is not widely standardized, its usage is inconsistent across languages and specialties. In many contexts, clinicians may simply refer to the technique as a long core biopsy or as an open/incisional biopsy with extended tissue retrieval.
