Abstract
Our study included 40 patients underwent laparoscopic colon resection using icg dye before and after the anastomosis to assess bowel perfusion and decrease postoperative leakage
Anastomotic leakage occurred in 10 patients related to many risk factors such as low anastomotic level, smoking, and splenic flexure immobilization
But overall ICG-enhanced fluorescence imaging is a safe and effective tool to increase visualization during laparoscopic surgery. Icg dye can be used intraoperative to assess the anastomotic perfusion to reduce post operative anastomotic leakage
Intraoperative angiography with indocyanine green to evaluate docking perfusion in patients undergoing laparoscopic colorectal resection.
Research background:
Significant advances have been made in video imaging for minor surgery over the past few years: the use of high-definition (HD) as well as three-dimensional (3-D) systems has proven to improve surgeon performance and patient safety. Recently, the enhanced dye indocyanine green has been introduced into laparoscopic surgery to improve vision and provide detailed anatomical information during surgery.
Anastomotic leakage is the most feared postoperative complication in colorectal surgery with often devastating clinical outcomes for the patient and significant economic consequences for the health care provider.
Based on the ability of the indocyanine green dye to become fluorescent upon excitation with near-infrared light, upon intravenous injection, we obtain real-time angiography that can be used to evaluate intestinal perfusion before and after colorectal anastomosis.
The aim of the research:
The aim of this study is to evaluate the utility of intraoperative assessment of anastomotic perfusion using indocyanine green angiographic dye in patients undergoing left-sided colectomy or rectum for colorectal anastomosis.
A prospective clinical study was conducted on 40 patients admitted to the Endoscopy Unit at Minya University Hospital. The selected patients were divided into two groups:
1- Passive leakage group
2- Positive leakage set
A comparison was made between the two groups in terms of the level of fusion, receiving chemotherapy before the operation, and moving the splenic flexure, and we obtained results of leakage occurring in 10 cases as a result of several risk factors such as not moving the splenic flexure, smoking, or delivery at a level close to the anus.
