RESUMEN
Hundreds of scientific documents have reported on the application of indocyanine green (ICG) in hepatobiliary surgery in the past 13 years, but few bibliometric studies have been conducted. This study aimed to identify the situations of authors, countries/regions, institutions, journals, and hot topics in this field. The overall status and prospects of the current research in this field can be elucidated by bibliometric analysis. Publications from 2008 to 2021 were retrieved from the Web of Science (WoS) Core Collection. The search terms included "liver," "hepatic," "gallbladder," "bile duct," "surgery," "hepatectomy," "ICG," "indocyanine green," and related synonyms. The full records of the search results were exported in text, and the cooperation network and hot topics were evaluated and visualized using CiteSpace software. The number of publications increased between 2008 and 2021. A total of 1527 publications were included in the results, and the frequency of citations was 30,742. The largest proportion of the publications emanated from Japan, and the majority of the papers were published by Kokudo. Tian Jie contributed the largest number of papers in China. Research was relatively concentrated among one country/region. The latest hotspots, "preservation" and "resistance", frequently occurred. Cooperation between authors, countries, and institutions needs to be strengthened for high-quality research. Recent studies have focused on hepatectomy, bile duct resection, liver transplantation, and tumors in this field. Future research may focus on other aspects, such as liver preservation and resistance.
RESUMEN
OBJECTIVE: Here, we aimed to compare early hepatectomy (EH) with delayed hepatectomy (DH) as a treatment for spontaneously ruptured hepatocellular carcinoma (HCC). METHODS: Several databases were systematically searched for eligible studies that compared DH with EH for spontaneously ruptured HCC treatment. Studies that met the inclusion criteria were reviewed systematically, and the reported data were aggregated statistically, using the RevMan v5.3 software. RESULTS: Seven studies were included, with a total of 385 patients, comprising of 224 EH cases and 161 DH cases. Compared with the EH group, incidence of intraoperative bleeding [mean difference (MD), 353.93; 95% CI, 230.04-447.83; P < 0.00001], volume of intraoperative blood transfusion (MD, 420.61; 95% CI, 354.40-486.81, P < 0.00001), and 30-day mortality rate (OR, 14.94; 95% CI, 1.76-126.66; P = 0.01) were significantly lower in the DH group. Furthermore, the 1-, 2-, and 3-year survival rates were significantly higher in the DH group [1-yearï¼hazard ratio (HR), 1.76; 95% CI, 1.06-2.94; P = 0.03; 2-yearï¼HR, 1.52; 95% CI, 1.02-2.25; P = 0.04; 3-year: HR, 1.53; 95% CI, 1.06-2.21; P = 0.02]. There was no difference between the groups in the 5-year survival rate (HR, 1.40; 95% CI, 0.92-2.11; P = 0.11). CONCLUSION: For resectable spontaneously ruptured HCC, DH could reduce intraoperative bleeding, intraoperative blood transfusion volume, and 30-day mortality rate and increase the 1-, 2-, and 3-year survival rates, endowing the patients with greater short- and long-term benefits during and following the surgery.
