Abstract

Final del formulario

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 = 0.03). 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.

Resumen

La dehiscencia anastomótica, temida en cirugía colorrectal, motiva la búsqueda de estrategias eficaces para mitigar su riesgo. El presente metaanálisis incluye todos los ensayos aleatorizados publicados que investigan y comparan el impacto de la angiografía con verde de indocianina (ICG) en esta complicación. Con cuatro estudios y 1.109 pacientes, el grupo con angiografía intraoperatoria ICG mostró una significativa reducción en la tasa de dehiscencia anastomótica en comparación con el grupo sin angiografía (7,3% vs 11,5%; OR:0,6; IC95%:0,4-0,9; p = 0,03). Estas diferencias sólo se mantuvieron en el subgrupo de cirugía rectal, sin prolongación del tiempo quirúrgico, ni aumento en morbimortalidad. No hubo diferencias en el grupo de cirugía de colon izquierdo. La evidencia proporcionada por este metaanálisis respaldaría la efectividad de la angiografía ICG para reducir la incidencia de fuga anastomótica en cirugía colorrectal, abogando por su integración en la práctica quirúrgica rutinaria.
