ObjectiveTo investigate the safety and feasibility of fluorescent guided laparoscopic central hepatic tumor resection via anterior transhepatic approach. MethodWe retrospectively analyzed the clinical data of three patients who underwent fluorescent guided laparoscopic central hepatic tumor resection via anterior transhepatic approach in Department of Hepatobiliary and Pancreas Minimally Invasive Surgery of Hunan Provincial People’s Hospital from April 2017 to April 2020.ResultsAll the three patients completed the operation pure laparoscopically. Pathology results showed one case of hepatocellular carcinoma and two cases of focal nodular hyperplasia, the tumor size range from 4–7 cm. The operation time was 240–320 min, and the blood loss was 150–500 mL. There was no intraoperative blood transfusion. The postoperative hospital stay was 10–30 days. Postoperative bile leakage occurred in one patient, which was cured by laparoscopic hepatectomy. Three patients were followed up for 8, 36, and 25 months, respectively, and all the patients survived and there was no tumor recurrence up to november 2020.ConclusionsLaparoscopic resection of central hepatic tumor is difficult and risky. Anterior transhepatic approach can maximize the preservation of liver parenchyma. In hepatobiliary and pancreatic centers with high volume of laparoscopic hepatectomy, this method is safe and feasible after strict patient selection, accurate preoperative evaluation, and fine intraoperative skills. Indocyanine green fluorescence navigation technology is helpful to accurately locate tumor during operation.
ObjectiveTo summarize the application status and progress of indocyanine green fluorescence imaging in laparoscopic anatomic liver resection , and to analyze its advantages, limitations, and prospects.MethodThe literatures about indocyanine green fluorescence imaging in laparoscopic anatomic liver resection were reviewed.ResultsIndocyanine green fluorescence imaging had been preliminarily used in the operation of liver tumors and had shown its unique value in the anatomical liver resection, providing a new way to reduce the recurrence of liver cancer, improve the therapeutic effect, and prolong the survival time of patients.ConclusionsThe clinical application of indocyanine green fluorescence imaging in anatomic liver resection is still at the stage of development and popularization. Although it has unique advantages and development potential, it needs to be further improved in the aspects of tissue penetration, specificity, and staining success rate.
Objective To investigate the value of indocyanine green fluorescence imaging in common bile duct reexploration. Methods The clinical data of 32 patients who underwent open common bile duct reexploration in the Affiliated Hospital of Southwest Medical University from January 2018 to December 2020 were collected retrospectively. All patients divided into the control group (conventional exploration group, 20 patients) and the fluorescence imaging group (using indocyanine green fluorescence imaging, 12 patients) according to the operational manner. The intraoperative and postoperative results of two groups were analyzed. Results The operative time [(165.2±6.9) min vs. (130.8±5.5) min], the time to find extrahepatic bile duct [(43.9±3.8) min vs. (23.1±4.1) min] and the amount of bleeding [(207.7±7.7) mL vs. (127.5±15.3) mL] in the control group were longer or more than those in the fluorescence imaging group (P<0.05). The incidence of postoperative infection in the control group [7 cases (35.0%) vs. 0 cases (0.0%)] and the length of hospital stay [(10.8±2.8) d vs. (7.1±1.3) d] were higher or longer than those in the fluorescence imaging group (P<0.05). There were no significant difference between the two groups in the incidence of postoperative bile fistula [6 cases (30.0%) vs. 2 cases (16.7%)] and the incidence of residual stones [3 cases (15.0%) vs. 3 cases (25.0%), P＞0.05]. Conclusion Indocyanine green fluorescence imaging appears to be a feasible, expeditious, useful, and effective imaging method while performing reexploration.
Objective To explore the accuracy and efficiency of indocyanine green fluorescence (ICGF) imaging in evaluating blood perfusion of parathyroid gland (PG) during total thyroidectomy. Methods Seventy patients who underwent total thyroidectomy and bilateral central lymph node dissection for papillary thyroid carcinoma (PTC) from March 2021 to December 2021 were enrolled and randomly divided into experimental group (ICGF imaging, n=35) and control group (normal treatment, n=35). Blood perfusion of PGs was evaluated by ICGF imaging and naked eye in each group respectively. The perfusion of PGs, incidence of hypoparathyroidism, and number of autotransplanted PGs were analyzed between the two groups. Results There was no difference between two groups in the incidence of transient hypoparathyroidism (P=0.339), and no one occurred permanent hypoparathyroidism. More PGs were autotransplanted in the experimental group compared to the control group (P＜0.001). At least one PG with good perfusion in the experimental group predicted an extremely high rate of normal parathyroid hormone levels of the patients postoperatively than the control group (P=0.003). Conclusion ICGF imaging can evaluate the blood perfusion of PGs accurately and guide their autotransplantation.
Objective To evaluate the effectiveness and safety of indocyanine green fluorescence method versus modified inflation-deflation method for thoracoscopic anatomic segmentectomy. Methods CNKI, Wanfang Database, China Biomedical Literature Database, Web of Science, Cochrane Library, EMbase, PubMed, Clinicaltrials.gov, were searched from 1 January 2000 to 1 May 2023, and controlled studies between indocyanine green fluorescence and modified inflation deflation method in thoracoscopic segmentectomy were collected. Meta-analysis was performed using Stata14MP and RevMan5.4. Results A total of 10 articles, including 1 156 patients, were identified. In thoracoscopic anatomic segmentectomy, indocyanine green fluorescence method had an advantage over modified inflation deflation method. The total incidence of postoperative complications decreased (OR=0.51, 95%CI 0.36 to 0.71, P<0.0001). The incidence of air leaks decreased (OR=0.50, 95%CI 0.31 to 0.80, P=0.004), the operation time shortened (MD=−25.81, 95%CI −29.78 to −21.84, P<0.00001), the length of postoperative hospital stays shortened (MD=−0.98, 95%CI −1.57 to −0.39, P=0.001), the rate of clear displaying for intersegmental boundary line increased (OR=5.79, 95%CI 2.76 to 12.15, P<0.00001). The difference was statistically significant. Conclusion Compared with modified inflation deflation method, indocyanine green fluorescence method can quickly and clearly display the intersegmental boundary line, reduce the difficulty of surgery, shorten the operation time, reduce the length of postoperative hospital stay, and provide reliably technical support for thoracoscopic anatomic segmentectomy. It is an effective and safe method, which is worthy of extensive application.
