It is unclear whether a distinction needs to be made. An observational study was undertaken to evaluate the predissection hepatocystic region (pre\u2010HCR) and the postdissection hepatocystic region (post\u2010HCR). Also, the dissection\u2010related changes to the contents of the pre\u2010HCR (\u201cproper HCT\u201d) were evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective review of a prospectively maintained database was done. The operative videos of patients who underwent fluorescence\u2010guided surgery from December 2021 to February 2022 were reviewed. Patients with gallstone disease without complications (GSD) were included in the study. Exclusion criteria were acute cholecystitis, choledocholithiasis, biliary pancreatitis, biliary fistulas, and gallbladder wall thickening of \u22653\u2009mm on ultrasonography.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirteen patients underwent LC for GSD using standard dissection methods. The boundaries of the pre\u2010HCR were identified before dissection in all patients. The dissection resulted in a quadrangular space lateral to the \u201cproper HCT\u201d in all. The post\u2010HCR contained the undissected \u201cproper\u2010HCT\u201d and the quadrangular space in all. The post\u2010HCR area was 4.4 times that of the pre\u2010HCR (3.2\u201313.1). The peritoneum over the \u201cproper HCT\u201d was unbreached in all patients, and the target structures were delineated outside of it. A critical view of safety (CVS) was demonstrated outside of the \u201cproper HCT\u201d in all patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>During near\u2010infrared fluorescence\u2010guided LC for GSD, there is no fat clearance in the \u201cHCT.\u201d The hepatocystic region before and at the conclusion were distinctly different.
