Advantages of ICG-guided laparoscopic resection in complicated diverticulitis: a narrative literature review

More than 10% of cases of acute diverticulitis may require surgical intervention. Despite the high morbidity and mortality rates, Hartmann's operation has been considered the “gold standard” in the treatment of complicated diverticulosis with peritonitis for many years. Contemporary treatment recommendations define laparoscopy as the method of choice for Hinchey stages II and III, allowing for laparoscopic resection with primary anastomosis, as well as laparoscopy with drainage. The inflammatory syndrome causes disruption of microcirculation and affects the trophicity of the intestinal wall, ultimately leading to the compromise of the anastomosis. The use of indocyanine green (ICG) angiography allows for the assessment of circulation and the prevention of severe complications. The use of ICG for visualization of the ureters also reduces the risk of iatrogenic lesions.
