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…
