RESUMEN
Background: This meta-analysis was dedicated to evaluating the safety and effectiveness of indocyanine green (ICG) -mediated fluorescence molecular imaging (FMI) technology in liver tumors resection. Methods: A literature search of PubMed, Embase databases, Cochrane Library, and Web of Science was performed to identify all clinical controlled studies exploring the effects of fluorescence imaging on liver tumors resection. Quality assessment and data extraction of studies were conducted independently by 3 reviewers. Mean difference (MD) and odds ratio (OR) with 95% confidence interval (CI) were calculated using a fixed-effects or random-effects model. The meta-analysis was performed with RevMan 5.3 software. Results: 14 retrospective cohort studies (RCSs) involving a total of 1227 patients were finally included. The results showed that Fluorescence-assisted liver tumors resection could improve the R0 resection rate (OR = 2.63; 95% CI: 1.46~4.73, p = 0.001), reduce overall complications (OR = 0.66; 95% CI: 0.44~0.97, p = 0.04), biliary fistula (OR = 0.20; 95% CI: 0.05~0.77, p = 0.02), intraoperative blood loss (MD = -70.76, 95% CI: -106.11 to -35.41; p < 0.0001), and shortens hospital stay (MD = -1.41, 95% CI: -1.90 to -0.92; p < 0.00001). There were no significant differences in the incidences of operative time (MD = -8.68, 95% CI: -18.59 to -1.22; p = 0.09), complications of grade III or above (OR = 0.73; 95% CI: 0.43~1.25, p = 0.26), liver failure (OR = 0.86; 95% CI: 0.39~1.89, p = 0.71), and blood transfusion (OR = 0.66; 95% CI: 0.42~1.03, p = 0.07). Conclusion: Current evidence suggests that ICG-mediated FMI technology could enhance the clinical effectiveness of patients with liver tumors resection and is clinically worthy of promotion.

RESUMEN
Background: Cholelithiasis is a frequently occurring disease in clinic. Due to changes in people's living environments, dietary habits and the aging population, cholelithiasis incidence is increasing. Currently, laparoscopic cholecystectomy (LC) is the preferred treatment for gallbladder stones, but the surgical method for patients with choledocholithiasis is controversial. An endoscopic retrograde cholangiopancreatography (pERCP) is performed preoperatively, followed by LC as the general treatment method. However, pERCP still has some disadvantages, such as prolonged hospital stay, increased incidence of postoperative pancreatitis, and increased duration of anesthesia. Therefore, intraoperative endoscopic retrograde cholangiopancreatography (iERCP) is proposed. Objective: To compare the efficacy and safety of one-stage treatment and two-stage treatment for the management of patients with cholecystolithiasis and choledocholithiasis. Search strategy: PubMed, Embase, Web of Science, and Cochrane databases were searched through October 2022. The search terms include cholangiolithiasis/bile duct stones/calculi, endoscopic retrograde cholangiopancreatography/ERCP, endoscopic sphincterotomy/EST, laparoendoscopic rendezvous (LERV), and laparoscopic cholecystectomy/LC. Selection criteria: For the treatment of patients with cholecystolithiasis and choledocholithiasis in adults, randomized controlled trials (RCTs) comparing LC with iERCP vs. pERCP followed by LC were conducted. Data collection and analysis: Data extraction and quality assessment were performed by two reviewers. We used Revman version 5.3 to analyze the collected data. The trials were grouped according to the evaluation results such as the overall mortality rate, overall morbidity rate, clearance rate of choledocholithiasis, incidence of pancreatitis, the length of hospitalization, and the length of operation. Results: 9 RCTs (950 participants) were included in this meta-analyses. The overall morbidity rate in LC + iERCP group is lower than that in LC + pERCP group (RR: 0.57, 95% CI = 0.41-0.79, p = 0.0008). The clearance rate of choledocholithiasis in LC + iERCP group was almost the same as that in LC + pERCP group (RR: 1.03, 95% CI = 0.98-1.08, p = 0.28). The incidence of pancreatitis in LC + iERCP group is lower than that in LC + pERCP group (RR: 0.29, 95% CI = 0.13-0.67, p = 0.004). The length of operation of the LC + iERCP group seems to be similar to that of the LC + pERCP group (MD: 16.63 95% CI = -5.98-39.24, p = 0.15). LC + iERCP group has a shorter length of hospitalization than that in LC + pERCP group (MD: -2.68 95% CI = -3.39--1.96, p < 0.00001). LC + iERCP group has lower postoperative second ERCP rate than that in LC + pERCP group (RR: 0.13, 95% CI = 0.03-0.57, p = 0.006). Conclusion: Our study suggest that LC + iERCP may be a better option than LC + pERCP in the management of patients with both cholecystolithiasis and choledocholithiasis. This procedure can reduce the overall incidence of postoperative complications, especially the occurrence of postoperative pancreatitis. It could shorten the length of hospital stay, reduce postoperative second ERCP rate.
