Description
Ko Oshita and co-authors identify conversion risks in keyhole liver surgery in a 2025 study. Minimally invasive liver removal is widely accepted now. Sometimes surgeons must switch to hand-assisted or open surgery mid-operation. No prospective work had mapped those risk factors.
Seven institutions enrolled patients with small solitary liver tumors. All began with the keyhole approach between 2020 and 2024. About eighty-six percent finished as planned. Twenty-seven patients needed conversion to another approach. A third or later liver operation strongly predicted conversion. Male sex also raised the odds significantly. Converted cases ran longer with more blood loss. Hospital stays stretched after conversion as well. A clamping maneuver was used less in those cases. The authors urge planning around repeat-surgery patients. Risk conversations before consent can use these numbers.
