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 evaluate the value of real-time indocyanine green fluorescence imaging navigation (ICG-FIN) in laparoscopic rectal cancer surgery. MethodsThe patients who adopted ICG-FIN during laparoscopic rectal cancer surgery in the Department of Anorectal Surgery of Xuzhou Central Hospital from April 2022 to June 2023 according to the inclusion and exclusion criteria (ICG-FIN group) were collected, meanwhile matching (1∶1) of patients who did not adopt ICG-FIN during laparoscopic surgery from January 2021 to May 2022 (control group). The general data, surgical conditions, intraoperative and postoperative outcomes between the two groups were compared. ResultsThere were 62 patients in the ICG-FIN group and 62 patients in the control group. There were no statistical differences in the gender, age, body mass index, comorbidities, and so on between the two groups (P>0.05). The tumor localization, lymph node tracing, fluorescence imaging of the intended resection of intestinal tract and anastomotic site were observed in the ICG-FIN group. Seven patients (11.3%) had changed in the intended resection of intestinal anastomotic line during surgery, while there were no changes of the surgical plan in the control group. There were no statistical differences (P>0.05) in terms of surgical method, operative time, intraoperative bleeding, proportion of ileostomy, time of the first postoperative exhaust, postoperative hospital stay, and incidence of short-term complications between the two groups. Compared with the control group, the incidence of anastomotic leakage was lower (P=0.012), and the number of lymph nodes cleaned was more (P=0.016) in the ICG-FIN group. However, there was no statistical difference in the number of positive lymph nodes detected between the two groups (P=0.343). ConclusionsAccording to the results of this study, ICG-FIN is a reliable and effective method during laparoscopic rectal cancer surgery, which can accurately localize tumor, trace and guide lymph node dissection. Real-time evaluation of intestinal blood flow perfusion is of great practical value in reducing anastomotic leakage.
