Utility of fluorescence-guided surgery in the laparoscopic approach of peritoneal carcinomatosis: two cases in our center

We present two patients with a diagnosis of peritoneal carcinomatosis (PC) originating from colorectal cancer (CRC) who were administered intravenous indocyanine green (ICG) preoperatively:

• 1

  A 75-year-old man with an implant in the left parietal peritoneum (Fig. 1a,b)

  
  

  Fig. 1.

  A) Small liver nodule; B) implant in the parietal peritoneum at the left iliac fossa; C) peritoneal nodule in the small intestine; D) fluorescence in small a intestine nodule.
• 2

  A 67-year-old man with a hyperfluorescent nodule in the proximal jejunum (Fig. 1c,d)

Indocyanine green fluorescence-guided surgery appears to be a useful tool in visualizing small lesions. In our cases, it was useful to confirm peritoneal nodules, to assess adequate resection margins, and to rule out a benign lesion.
