ISFGS Creates FGS Guidelines Using the Delphi Consensus Model
The use of ICG and fluorescence imaging is growing exponentially. However, variation continues to exist in how ICG is dosed.
Guidelines on the use of Fluorescence Guided Surgery using a Delphi Model
ISFGS is leading the way in efforts to establish standards in the field of Fluorescence-Guided Surgery, and have chosen to use the Delphi method in order to establish guidelines for the field. Delphi studies are a means by which a group of experts can either come to consensus regarding certain …
Near-infrared Fluorescence Imaging for Sentinel Lymph Node Identification in Melanoma Surgery
Abstract Although less common than other types of skin cancers, melanoma is accountable for the majority of skin cancer-related deaths. The standard management for patients with clinically negative nodes includes a sentinel lymph node (SLN) biopsy, which is commonly performed using a combination of radioactive tracer (Tc-99) and a blue dye (isosulfan or patent blue).…

Fluorescence Incisionless Cholangiography
A live surgery video preseted by Dr. Fernando Dip, Dr. Jorge Falco, Dr. Raul Pecero, Dr. Fernanda Montesinos, Dr. Lucia Infante and Dr. Raul Rosenthal. Presented here is a case of a patient with symptomatic gallbladder stones who underwent a laparoscopic cholecystectomy with fluorescent cholangiography. 45 minutes before the procedure began, a dose of 0.05…
Nerve spectroscopy: understanding peripheral nerve autofluorescence through photodynamics
Methods: Samples from various human peripheral nerves were selected postoperatively. Nerve fibers were divided into three groups: Group A nerve fibers were washed with a physiologic solution; Group B nerve fibers were fixated with formaldehyde for 6 h first, and then washed with a physiologic solution; Group C nerve fibers were fixated with formaldehyde for six…
Nerve autofluorescence in near-ultraviolet light markedly enhances nerve visualization in vivo
Methods: We exposed sciatic nerves within the posterior thigh in five 250-300 gm Wistar rats, then observed them at four different NUV intensity levels: 20%, 35%, 50%, and 100%. Brightness of fluorescence was measured by fluorescence spectroscopy, quantified as a fluorescence score using Image-J software, and statistically compared between nerves, background, and both an artery and…
Widespread anorectal lymphovascular networks and tissue drainage: analyses from submucosal india ink injection and indocyanine green fluorescence imaging
Methods In this descriptive study, we performed microanatomical evaluations and intraoperative imaging analysis in a cadaver and patients with rectal cancer. Specimens with India ink injection were collected from a cadaver and six patients who underwent abdominoperineal resection. Intraoperative indocyanine green fluorescence imaging was performed on four patients who underwent surgery for lower rectal cancer.…
Does Near-infrared Fluorescent Cholangiography with Indocyanine Green Reduce Bile Duct Injuries and Conversions to Open Surgery During Laparoscopic or Robotic Cholecystectomy?
Methods A thorough PubMed search was conducted to identify randomized clinical trials and nonrandomized clinical trials with ≥100 patients. Because all near-infrared fluorescent cholangiography studies were published since 2013, only studies without near-infrared fluorescent cholangiography published since 2013 were included for comparison. Incidence estimates, weighted and unweighted for study size, were adjusted for acute versus…
Artificial Intelligence Indocyanine Green (ICG) Perfusion for Colorectal Cancer Intra-operative Tissue Classification
METHODS Intraoperative white-light and NIR-fluorescence multispectral videos of primary colorectal tumours in patients undergoing diagnostic and therapeutic intervention were used for both AI model training and testing. These contained mucosal tumours subsequently determined as being benign or malignant with their surrounding area of macroscopically normal tissue, as viewed in both white light and NIR after…
