Abstract:Objective To explore the nursing process of endoscopic retrograde cholangiopancreatography (ERCP) drainage in patients with hilar cholangiocarcinoma (HCCA). Methods A retrospective summary of surgical nursing cooperation was made on the 10 HCCA patients undergoing IQQA? (intelligent/interactive qualitative and quantitative analysis) liver system-assisted ERCP in Nanjing Drum Tower Hospital from January 2017 to December 2018. Results IQQA?-liver assisted ERCP biliary drainage was successfully completed in 10 patients. The mean liver volume in the drainage area was (627.7±115.7) cm³. After drainage for 14 to 39 days, the average total bilirubin content decreased to (59.3±11.8) μmol/L, in accord with the requirements of subsequent radical resection of HCCA. There was no persistent biliary tract infection, liver abscess or other common biliary complications. Nursing cooperation focused on participating in preoperative discussion, thorough understanding of the operation and IQQA?-liver system in analyzing the anatomical sites and tumor space of patients with biliary obstruction, fully preparing surgical instruments and environment and preoperative nursing of the patients. During the operation, the disinfection and isolation system was strictly implemented, and superselecting the target bile duct was performed based on skillfully cooperating with doctors when Radifocus guide wire was used for intrahepatic bile duct superselective intubation with the guide sign of three-dimensional bile duct model analyzed by IQQA? -liver system. The detailed postoperative handover and observation are helpful to reduce the jaundice and create conditions for further surgical treatment.
