A comparison of quantitative versus qualitative indocyanine green imaging for anastomotic viability assessment: Impact on surgeons’ intraoperative decision-making confidence

Xuan Qiu, Victor A. Kashchenko, Anatoly A. Zavrazhnov, Timur S. Lankov et autres

Anastomotic leak (AL) remains a serious and feared complication. While indocyanine green (ICG) fluorescence angiography is widely adopted. However, its assessment is typically qualitative and subjective. Quantitative ICG (q-ICG) offers an objective alternative, yet its impact on the surgeon's decision-making confidence remains …
