An iodine-125 seed strand combined with a metal stent versus a metal stent alone for obstructive jaundice caused by pancreatic ductal adenocarcinoma

PurposeThe purpose of this study was to assess the efficacy of an iodine-125 (¹²⁵I) seed strand combined with a metal stent compared with a metal stent for treatment of obstructive jaundice caused by pancreatic ductal adenocarcinoma (PDAC).Methods and MaterialsA retrospective analysis was carried out of patients who were referred to Shanghai Zhongshan Hospital of Fudan University with a diagnosis of PDAC between January 1, 2010 and January 31, 2019. A total of 110 consecutive patients with obstructive jaundice caused by PDAC were divided into the iodine-125 seed strand combined with a metal stent group (Group A = 48) and the metal stent group (Group B = 62). The primary outcome was stent obstruction–free survival time, and secondary outcomes were overall survival and complications.ResultsThe median stent obstruction–free survival time was 133.0 (95% confidence interval (CI): 166.093–149.907) days, and the median overall survival was 212.0 (95% CI: 187.183–236.817) days in all patients. Median stent obstruction–free survival time was 175 days (95% CI 103.165–246.835 days) in Group A versus 120 days (95% CI 87.475–152.525 days) in Group B (p = 0.035). A lower Eastern Cooperative Oncology Group (ECOG) score (p = 0. 000) and iodine-125 seed strand combined with metal stent implantation (p = 0.008) were associated with a longer stent obstruction–free survival time. Obstruction length (p = 0.083), ECOG score (p = 0.000), and iodine-125 seeds (p = 0.037) might have potential impact on stent obstruction–free survival time and were included for multivariable analysis using the Cox proportional hazards model. Stent restenosis was observed in 18.8% (9/48) of patients in Group A and 54.8% (34/62) in Group B, respectively. There was no significant difference in median survival between Group A and Group B (p = 0.409). The median survival in Group A was 209 days (95% CI 150.750–267.250) and 202 days (95% CI 190.624–233.376) in Group B. The median survival of patients with a lower ECOG score was better than that of patients with a higher ECOG score (267 days vs 132 days, p = 0.000). The Grade 3 or 4 complications occurred in 4 (8.3%) of the 48 patients in Group A (one case of hemobilia, one case of liver abscess, two cases of choleperitonitis) and in 5 (8.1%) of the 62 patients in Group B (one case of hemobilia, two cases of liver abscess, two cases of choleperitonitis) (p = 0.972).ConclusionsImplantation of an iodine-125 seed strand combined with a metal stent provides longer obstruction-free survival time compared with a metal stent in patients with obstructive jaundice caused by PDAC. It seems reasonable to choose an iodine-125 seed strand combined with a metal stent as a treatment for these patients.

Metallic stents in malignant biliary obstruction

Purpose Retrospective analysis of our results with metallic stent placement for malignant biliary strictures. We sought to determine parameters that influence stent patency. Methods A total of 95 Wallstents were implanted in 65 patients (38 men, 27 women; mean age, 65.1 years) with malignant biliary obstruction. Serum bilirubin levels were assessed in 48 patients; the mean value prior to intervention was 15.0 mg/dl. Results In 12 patients (21%) complications occurred as a result of percutaneous transhepatic drainage. Stent implantation was complicated in 13 patients, but was possible in all patients. A significant decrease in bilirubin level was seen in 83.3% of patients following stent implantation. Approximately 30% of patients developed recurrent jaundice after a mean 97.1 days. In 9 patients (15%) the recurrent jaundice was caused by stent occlusion due to tumor growth. The mean follow-up was 141.8 days, the mean survival 118.7 days. Patients with cholangiocarcinomas and gallbladder carcinomas had the best results. Worse results were seen in patients with pancreatic tumors and with lymph node metastases of colon and gastric cancers. Conclusions The main predictive factors for occlusion rate and survival are the type of primary tumor, tumor stage, the decrease in bilirubin level, and the general condition of the patient.

Magnetic resonance cholangiography: comparison of two- and three-dimensional sequences for assessment of malignant biliary obstruction

The purpose was to retrospectively compare two-dimensional (2D) magnetic resonance cholangiography (MRC) including breath-hold single-shot rapid acquisition with relaxation enhancement (RARE) and multislice half-Fourier RARE versus navigator-triggered 3D-RARE MRC in the evaluation of biliary malignancy. MRC findings were evaluated in 31 patients with malignant biliary obstruction, including biliary malignancy, gallbladder carcinoma, and ampullary cancer. Two observers independently reviewed the images to assess the overall image quality, artifacts, ductal conspicuity, extent of disease, diagnostic confidence of tumor extent, and origin of tumor. The results were compared with surgical and histopathologic findings. Studies obtained with 3D-MRC were of significantly higher technical quality than those obtained with 2D-MRC. However, the accuracy between two sequences for classification of tumor showed no statistical significance. There was no significant difference between the Az values of 2D- and 3D-MRC for overall tumor extent in bilateral second order branch, intrapancreatic common bile duct (CBD) involvement (Az = 0.889, 0.881 for 2D and Az = 0.903, 0.864 for 3D). Nor was there a significant difference between two sequences in the assessment of the origin of tumor. Although 3D-MRC has superior image quality over 2D-MRC, 3D-MRC showed no statistically significant difference in accuracy compared with 2D-MRC for evaluating the extent of disease in malignant biliary obstructions.

Management of malignant biliary obstruction: Technical and clinical results using an expanded polytetrafluoroethylene fluorinated ethylene propylene (ePTFE/FEP)-covered metallic stent after 6-year experience

To evaluate the efficacy and safety of an expanded polytetrafluoroethylene-fluorinated ethylene-propylene (ePTFE/FEP)-covered metallic stent in the management of malignant biliary obstruction. Eighty consecutive patients with malignant common bile duct strictures were treated by placement of 83 covered metallic stents. The stent-graft consists of an inner ePTFE/FEP lining and an outer supporting structure of nitinol wire. Clinical evaluation, assessment of serum bilirubin and liver enzyme levels were analyzed before biliary drainage, before stent-graft placement and during the follow-up period at 1, 3, 6, 9 and 12 months. Technical success was obtained in all cases. After a mean follow-up of 6.9±4.63 months, the 30-day mortality rate was 14.2%. Survival rates were 40% and 20.2% at 6 and 12 months, respectively. Stent-graft patency rates were 95.5%, 92.6% and 85.7% at 3, 6 and 12 months, respectively. Complications occurred in five patients (6.4%); among these, acute cholecystitis was observed in three patients (3.8%). A stent-graft occlusion rate of 9% was observed. The percentage of patients undergoing lifetime palliation (91%) and the midterm patency rate suggest that placement of this ePTFE/FEP-covered stent-graft is safe and highly effective in achieving biliary drainage in patients with malignant strictures of the common bile duct.
