Impacto de la angiografía con verde de indocianina en la tasa de dehiscencia anastomótica en cirugía colorrectal. Revisión sistemática y metaanálisis de estudios aleatorizados

Anastomotic dehiscence, a feared complication in colorectal surgery, motivates the search for effective strategies to mitigate its risk. This meta-analysis encompasses all published randomized trials investigating and comparing the impact of indocyanine green (ICG) angiography on this complication. With four studies and 1,109 patients, the intraoperative ICG angiography group demonstrated a significant reduction in the overall rate of anastomotic dehiscence compared to the non-angiography group (7.3% vs. 11.5%; OR: 0.6; 95% CI: 0.4-0.9; P = .03). These differences were maintained in rectal surgery subgroup, with no prolongation of surgical time or increase in morbidity and mortality. There were no differences in the left colon surgery group. The evidence provided by this meta-analysis would support the effectiveness of ICG angiography in reducing the incidence of anastomotic leakage in colorectal surgery, advocating for its integration into routine surgical practice.
