Nonostante i recenti avanzamenti nelle tecniche chirurgiche, la complicanza più frequente in chirurgia colorettale rimane la deiscenza anastomotica. La patogenesi della deiscenza anastomotica rimane ancora poco chiara. Numerosi studi hanno trovato una correlazione tra una scarsa ossigenazione tissutale secondaria ad una inadeguata perfusione e la deiscenza anastomotica. Per un chirurgo non è semplice quantificare intraoperatoriamente la perfusione prima e durante il confezionamento dell’anastomosi. Il verde indocianina appare essere una nuova tecnologia nella prevenzione della deiscenza anastomotica in chirurgia colorettale. Attualmente, questa tecnologia è stata proposta nel determinare l’anatomia, la perfusione tissutale ed il drenaggio linfatico. In chirurgia colorettale, la fluorescenza al verde indocianina può aiutare il chirurgo nel valutare la perfusione dell’anastomosi ed evitare il rischio di deiscenza anastomotica. La recente introduzione della chirurgia robotica presenta ulteriori vantaggi rispetto alla chirurgia laparoscopica: un telecamera 3D controllata dal chirurgo, sette gradi di libertà degli strumenti, meccanismi anti-tremore. In questo studio analizziamo l’uso della fluorescenza al verde indocianina nella chirurgia robotica colo-rettale nella prevenzione del rischio di deiscenza anastomotica.

Abstract
Despite recent advances in surgical techniques, the most common complication in colorectal surgery remains anastomotic leakage (AL). Pathogenesis of AL is still unclear. Several studies have found correlation between poor local tissue oxygenation secondary to inadequate perfusion and AL. For a surgeon is not simple to quantify intraoperatively perfusion of bowel before and during anastomosis. Indocyanine Green (ICG) appears to be a new technology on preventing AL in colorectal surgery. Actually, this technology has been proposed to assess anatomy, perfusion of tissue and lymphatic drainage. In colorectal surgery, ICG fluorescence imaging can aid surgeon in detecting anastomotic perfusion and avoid risk of AL. Recent introduction of robotic surgery presents additional advantages over laparoscopic surgery: 3D camera controlled by surgeon, seven degrees of freedom of instruments, tremor-filtering mechanism. In this study we investigated the use of indocyanine green-enhanced fluorescence in robotic colorectal surgery to prevent risk of AL.File | Dimensione | Formato | |
