Core Tip
Core Tip: We demonstrated an effective, reproducible technique for repeat Pringle maneuver in challenging minimally invasive repeat liver resection (MISRLR). We retrospectively evaluated 72 patients who underwent MISRLR and examined the impact of a modified Pringle taping technique guided by the caudate lobe of the liver as an anatomical landmark. A marked improvement in success rate of Pringle taping from 33.0% to 91.4% occurred following this modification with low morbidity and no mortality. Thus, the proposed method may enhance both safety and reproducibility in MISRLR, particularly for patients with a history of open liver resection.
