Abstract:
Objective:To investigate the clinical value of three-dimensional (3D) visualization technology in the precise drainage through endoscopic retrograde biliary drainage (ERBD) for hilar cholangiocarcinoma.Methods:Clinical data of 42 patients with highly suspected hilar cholangiocarcinoma who underwent ERBD in Qinghai University Affiliated Hospital from September 2019 to August 2022 were retrospectively collected. Twenty patients underwent 3D biliary tract reconstruction before surgery (the reconstruction group) and 22 others did not undergo 3D biliary tract reconstruction before surgery (the non-reconstruction group). The surgery time, X-ray exposure time, the technical success rate, the clinical success rate, incidence of postoperative complications, recent and short-term endoscopic retrograde cholangiopancreatography (ERCP) reintervention rate of the two groups were compared.Results:There was no significant difference in preoperative baseline data between the two groups ( P>0.05). ERBD was conducted successfully in all 42 patients. The operation time in the reconstruction group [35.00 (25.00, 57.50) min] was significantly shorter than that in the non-reconstruction group [60.00 (33.75, 60.00) min] with significant difference ( Z=-2.251, P=0.024). There was no significant difference in the X-ray exposure time between the two groups [10.00 (5.00, 12.00) min VS 10.55 (9.50, 17.50) min, Z=-1.552, P=0.121]. The technical success rates of both groups were 100.0%, and the clinical success rate of the reconstruction group was higher than that of the non-reconstruction group [70.0% (14/20) VS 31.8% (7/22)] with significant difference ( χ 2=6.109, P=0.013). There was no significant difference in the incidence of postoperative complications between the two groups [20.0% (4/20) VS 22.7% (5/22), χ 2=0.141, P=0.708]. All patients were followed up for 6 months after the procedure. The median survival time was 3.91 months in the reconstruction group and 2.78 months in the non-reconstruction group. There was no ERCP intervention in the reconstruction group within 2 weeks after the procedure, while 4 cases (18.2%) in the non-reconstruction group received 6 ERCP interventions due to cholangitis and postoperative pancreatitis. Within 2 weeks to 3 months, 2 patients (10.0%) in the reconstruction group received 4 ERCP interventions for cholangitis, and 2 patients (9.1%) in the non-reconstruction group received 3 ERCP interventions for cholangitis. There was no significant difference in recent ( χ 2=2.183, P=0.140) or short-term ( χ 2=0.000, P=1.000) ERCP reintervention rate between the reconstruction group and the non-reconstruction group. Conclusion:3D visualization biliary duct reconstruction technology can measure the volume of liver drainage for hilar cholangiocarcinoma, shorten the operation time and improve the clinical success rate through precise preoperative planning, which is worth of promotion.
