Abstract:
Objective:To compare the efficacy and safety of a new type of plastic biliary stent modified based on the pigtail nasobiliary duct and the common plastic biliary stent for hilar cholangiocarcinoma.Methods:Data of a total of 38 patients with obstructive jaundice caused by hilar cholangiocarcinoma who received endoscopic retrograde cholangiopancreatography (ERCP) palliative treatment at the Endoscopy Center, General Hospital of Northern Theater Command from June 2018 to December 2020 were collected, including 20 cases using the new type of plastic biliary stent (the new stent group), and 18 cases using the common plastic stent (the common stent group). Patients were followed up to May 30, 2021. The procedure time, hospital stay, postoperative biliary infection incidence, the bilirubin decrease, and the patency time of the stents in the two groups were compared.Results:The procedure time was 19.85±1.07 minutes in the new stent group and 22.00±3.38 minutes in the common stent group, respectively, showing no significant difference between them ( t=1.26, P=0.607). The lengths of hospital stay of the two groups were 11.45±2.39 days and 11.33±3.51 days, respectively, showing no significant difference between them ( t=-0.52, P=0.938). The median margins of total bilirubin reduction in the two groups were 122.85 μmol/L and 96.25 μmol/L, respectively, with significant difference ( Z=-2.03, P=0.042). The incidence of long-term cholangitis of the new stent group was significantly lower than that of the common stent group [10.0% (2/20) VS 44.4% (8/18), P=0.027]. The patency time of the new stent group was significantly longer than that of the common stent group (109.45±32.67 days VS 82.11±20.95 days) with significant difference ( t=2.23, P=0.032). Conclusion:In the palliative treatment of hilar bile duct obstruction, the new plastic bile duct stent modified based on pigtail type can reduce the incidence of long-term cholangitis and prolong the patency of bile duct stent compared with the common stent group.
