背景与目的 Mirizzi综合征（MS）是胆囊炎和慢性胆石症的罕见并发症。随着微创技术的发展，越来越多的I型MS采用腹腔镜胆囊切除术（LC）进行治疗，而术中胆道损伤仍是最严重的并发症，能否在术中准确辨别胆管是减少胆道损伤的关键。吲哚菁绿（ICG）荧光导航目前越来越广泛应用于肝胆外科腹腔镜手术的临床运用，该技术可以很好地显示肝脏门静脉流域，在肝脏解剖性切除中发挥重要作用。ICG在代谢过程中通过肝细胞摄取进入胆汁通过胆道排入十二指肠，能对整个胆道系统解剖结构进行导航示踪。因此，本研究旨在探讨ICG在LC治疗I型MS中胆道识别导航作用效果。方法 回顾性分析昆明医科大学第二附属医院2019年10月—2022年1月收治的67例行LC的I型MS患者临床资料。其中35例行ICG荧光导航下LC（荧光导航组），32例行常规LC（常规手术组）。比较两组患者的相关临床指标。结果 两组术前一般资料及实验室指标差异均无统计学意义（均P>0.05）。与常规手术组比较，荧光导航组平均手术时间（74.66 min vs. 93.03 min）、平均术中出血量（20.43 mL vs. 57.34 mL）、中转开腹率（0 vs. 12.5%）均明显降低（均P<0.05）；平均术后第1天引流量（25.43 mL vs. 36.63 mL）、平均拔管时间（1.29 d vs. 1.91 d）、平均术后住院时间（2.8 d vs. 3.66 d）、平均总住院费用（11 349.43元 vs. 12 907.41元）均明显减少（均P<0.05）。术后荧光导航组发生腹部切口感染2例，常规手术组发生胆管损伤2例，胆汁漏2例，腹部切口感染4例，荧光导航组术后总并发症发生率明显低于常规手术组（5.7% vs. 25.0%，P=0.039）。结论 ICG荧光导航可实时显示胆道系统、减少术中出血、缩短手术时间、降低中转开腹、减少并发症发生率、预防胆道损伤。
Background and Aims Mirizzi syndrome (MS) is a rare complication of cholecystitis and chronic cholelithiasis. With the development of minimally invasive techniques, laparoscopic cholecystectomy (LC) is increasingly being used for the treatment of type I MS, in which, the intraoperative biliary tract injury is still the most serious complication. At present, indocyanine green (ICG) fluorescent navigation technique is more and more widely being used in the clinical practice of laparoscopic hepatobiliary surgery. This technique can well display the drainage area of the hepatic portal vein and play an important role in anatomical liver resection. During metabolism, ICG is taken up by hepatocytes and excreted into bile and thereby delivered into the duodenum through the biliary tract, which can guide and trace the anatomical structure of the entire biliary tract system. Therefore, this study was performed to investigate the efficacy of ICG in identification and navigation of biliary tract during LC for type I MS.Methods The clinical data of 67 patients with type I MS undergoing LC in the Second Affiliated Hospital of Kunming Medical University from October 2019 to January 2022 were retrospectively analyzed. Of the patients, 35 cases underwent LC under the guidance of intraoperative fluorescence navigation using ICG (fluorescence navigation group), and 32 cases underwent conventional LC (conventional surgery group). The main clinical variables were compared between the two groups of patients.Results There were no significant differences in preoperative data and laboratory measurements between the two groups of patients (all P>0.05). In fluorescence navigation group compared with conventional surgery group, the mean operative time (74.66 min vs. 93.03 min), mean intraoperative blood loss (20.43 mL vs. 57.34 mL) and open conversion rate (0 vs. 12.5%) were significantly reduced; the average drainage volume on postoperative day 1 （25.43 mL vs. 36.63 mL）, average time to tube removal (1.29 d vs. 1.91 d), average length of postoperative hospital stay (2.8 d vs. 3.66 d) and average total hospitalization cost (11 349.43 yuan vs. 12 907.41 yuan) were significantly decreased (all P<0.05). After operation, abdominal wound infection occurred in 2 cases in fluorescence navigation group, while biliary tract injury occurred in 2 cases, bile leakage occurred in 2 cases, and abdominal wound infection occurred in 4 cases in conventional surgery group. The overall incidence rate of postoperative complications in fluorescence navigation group was significantly lower than that in conventional surgery group (5.7% vs. 25.0%, P=0.039).Conclusion ICG fluorescent navigation can display biliary tract system in real time, reduce intraoperative bleeding, operative time, conversion to open surgery and incidence of complications, and prevent biliary tract injury.
