Which biopsy method should be avoided during laparoscopy?

• A. Electrocautery
• B. Peritoneal washings
• C. FNA
• D. Core needle

Answer: (D)

During laparoscopy, avoid methods that create a tract for tumor cells to spread and implant on port sites. A core needle biopsy uses a relatively large needle that passes through the abdominal wall into the lesion, disrupting tissue and the tumor capsule. This creates a route for shedding cells and seeding the peritoneum or port sites, which can worsen tumor spread and complicate staging. Safer options such as peritoneal washings and smaller, targeted sampling with minimal disruption reduce this risk and are preferred when tissue is needed. Thermal methods like electrocautery can cause tissue artifact and are not ideal for reliable histology, whereas the key concern with the core needle is the potential for dissemination along the needle tract.
