[PMID: 39138774 DOI: 10.1245/s10434-024-16040-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2024] [Accepted: 08/01/2024] [Indexed: 08/15/2024]
Abstract
BACKGROUND The regions of the liver with cholestasis caused by biliary tumors or thrombosis can be distinctly identified using indocyanine green (ICG) fluorescence imaging.1 The authors' team reported the application of bile-duct obstructed area imaging (BOAI) to assist open hepatectomy for intrahepatic cholangiocarcinoma (ICC) combined with intrahepatic bile duct obstruction previously.2 This video is the first report of real-time BOAI-guided three-dimensional (3D) laparoscopic hepatectomy using a 3D-4K fluorescence imaging system. METHODS A 65-year-old man was admitted to the authors' institution with clonorchiasis. Preoperative computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) showed an obstruction and diffuse dilation of the right hepatic duct. A 15-min retention of ICG (ICG R15) was performed 5 days before the operation, with a 3.3% result. Preoperative planning involved performing laparoscopic right hemi-hepatectomy with regional lymph node dissection assisted by visualization technology.3 During the procedure, significant fluorescence accumulation in the right liver was shown by fluorescence imaging. With the guidance of real-time BOAI (Fig. 1), the regions of biliary obstruction were precisely resected, and the middle hepatic vein (MHV) was passively and adequately exposed on the cutting plane. Fig. 1 Administration steps for real-time bile duct-obstructed area imaging. A ICG is injected intravenously 3-5 days before operation at a dose of 0.5 mg/kg. B ICG is accumulated in the whole liver within a few minutes after injection. C ICG is selectively absorbed by the liver and excreted into the intestines, whereby it is retained in areas of biliary obstruction RESULTS: The histopathologic diagnosis indicated high-grade intraepithelial neoplasia of the right bile duct tumor without lymph node metastases and clonorchiasis. The duration of the operation was 300 min, with an intraoperative blood loss of 50 ml. No postoperative complications occurred, and the patient was discharged after 7 days. CONCLUSION Laparoscopic right hemi-hepatectomy for the bile-duct obstructed area with the guidance of real-time BOAI is feasible and effective.

Indocyanine green fluorescence imaging to localize insulinoma and provide three-dimensional demarcation for laparoscopic enucleation: a retrospective single-arm cohort study. Int J Surg 2023; 109:821-828. [PMID: 37026828 PMCID: PMC10389620 DOI: 10.1097/js9.0000000000000319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Accepted: 02/20/2023] [Indexed: 04/08/2023]
Abstract
BACKGROUND Indocyanine green (ICG) fluorescence imaging is a new technology that can improve the real-time location of tumor edges and small nodules during surgery. However, no study has investigated its application in laparoscopic insulinoma enucleation. This study aimed to evaluate the feasibility and accuracy of this method for intraoperative localization of insulinomas and margin assessment during laparoscopic insulinoma enucleation. MATERIALS AND METHODS Eight patients who underwent laparoscopic insulinoma enucleation from October 2016 to June 2022 were enrolled. Two methods of ICG administration, ICG dynamic perfusion and three-dimensional (3D) demarcation staining, were utilized in the laparoscopic insulinoma enucleation. Tumor-to-background ratio (TBR) and histopathologic analysis were used to evaluate the feasibility and accuracy of these novel navigation methods in laparoscopic insulinoma enucleation. RESULTS All eight enrolled patients underwent both ICG dynamic perfusion and 3D demarcation staining. ICG dynamic perfusion images were available for six of them, among which five tumors could be recognized by TBR (largest TBR in each case 4.42±2.76), while the other could be distinguished by the disordered blood vessels in the tumor area. Seven out of eight specimens had successful 3D demarcation staining (TBR 7.62±2.62). All wound bed margins had negative frozen sections and final histopathologic diagnoses. CONCLUSIONS ICG dynamic perfusion may be helpful in observing the abnormal vascular perfusion of tumors, providing similar functionality to intraoperative real-time angiography. ICG injection under the tumor pseudocapsule may be a useful method for acquiring real-time, 3D demarcation for the resection of insulinoma.

[PMID: 35230491 PMCID: PMC9206608 DOI: 10.1007/s00259-022-05730-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Accepted: 02/13/2022] [Indexed: 02/06/2023]
Abstract
Purpose China has the largest cancer population globally. Surgery is the main choice for most solid cancer patients. Intraoperative fluorescence molecular imaging (FMI) has shown its great potential in assisting surgeons in achieving precise resection. We summarized the typical applications of intraoperative FMI and several new trends to promote the development of precision surgery. Methods The academic database and NIH clinical trial platform were systematically evaluated. We focused on the clinical application of intraoperative FMI in China. Special emphasis was placed on a series of typical studies with new technologies or high-level evidence. The emerging strategy of combining FMI with other modalities was also discussed. Results The clinical applications of clinically approved indocyanine green (ICG), methylene blue (MB), or fluorescein are on the rise in different surgical departments. Intraoperative FMI has achieved precise lesion detection, sentinel lymph node mapping, and lymphangiography for many cancers. Nerve imaging is also exploring to reduce iatrogenic injuries. Through different administration routes, these fluorescent imaging agents provided encouraging results in surgical navigation. Meanwhile, designing new cancer-specific fluorescent tracers is expected to be a promising trend to further improve the surgical outcome. Conclusions Intraoperative FMI is in a rapid development in China. In-depth understanding of cancer-related molecular mechanisms is necessary to achieve precision surgery. Molecular-targeted fluorescent agents and multi-modal imaging techniques might play crucial roles in the era of precision surgery.
