Hilar cholangiocarcinoma (CC) is a common malignant tumor with high malignancy and poor prognosis. Most patients have lost the opportunity to undergo radical surgery when diagnosed. Although palliative drainage or biliary stent placement is a preferable choice, the tumor cannot be controlled. This study aimed to develop a novel brachytherapy drainage tube for low-dose-rate brachytherapy with an effective drainage, thereby prolonging the survival time of patients.
A 54-year-old male patient had undergone choledochal stent implantation due to obstructive jaundice. He was admitted to the hospital because of the recurrence of jaundice. Preoperative imaging and pathological biopsy revealed hilar CC (Bismuth-Corlette type IIIa). First, the patient underwent percutaneous transhepatic cholangial drainage and the symptoms of jaundice gradually relieved. To further treat hilar CC and remove the biliary drainage tube as far as possible, the patient chose to use the novel brachytherapy drainage tube after a multi-disciplinary consultation. After 1 mo of brachytherapy, the re-examination revealed that the obstructive lesions disappeared, and the drainage tube was finally removed. During the following 10 mo of follow-up, the patient's hilar CC did not recur.
The novel brachytherapy drainage tube may be a new choice for patients with unresectable hilar CC.
Core Tip: This study aimed to develop a novel biliary drainage tube for low-dose-rate brachytherapy, which had a central cavity for drainage and bilateral cavities to fill 125I seeds. It was placed in a patient with unresectable hilar cholangiocarcinoma, and the obstruction was relieved 1 mo later. After 2 wk of observation, the biliary drainage tube was successfully removed, thereby improving the quality of life of the patient. No complications occurred, and obstructive jaundice did not recur during the follow-up. It was concluded that the novel brachytherapy drainage tube might be a novel choice for patients with unresectable hilar cholangiocarcinoma.
