Outline the rationale for percutaneous liver biopsy followed by laser photocoagulation as an alternative to transjugular liver biopsy in patients with coagulopathy and demonstrate the efficacy and safety of the procedure.

1. Define coagulopathy. 2. Discuss benefits and drawbacks of transjugular and percutaneous liver biopsy. 3. Review laser photocoagulation and its uses. 4. Outline the rationale for percutaneous liver biopsy followed by laser photocoagulation in patients with coagulopathy. 5. Describe the photocoagulation technique. 6. Present cases of percutaneous liver biopsy followed by laser photocoagulation.

Transjugular liver biopsy is used in patients with coagulopathy, as bleeding is reduced by egress into the hepatic veins. Transjugular liver biopsy, however, provides less diagnostic specimens. While percutaneous liver biopsy provides more diagnostic specimens, studies have shown a risk of hemorrhage. Laser photocoagulation has been used in the treatment of peptic ulcers and telangiectasias, opening the door to its use as an adjunct for other interventions. This exhibit aims to outline the rationale for percutaneous liver biopsy followed by laser photocoagulation as an alternative to transjugular liver biopsy in patients with coagulopathy and demonstrate its feasibility, efficacy, and safety.
