PURPOSE: To compare the effectiveness, adverse events (AEs), stent patency, and patient survival with suprapapillary and transpapillary uncovered self-expandable metallic stent placement for perihilar cholangiocarcinoma.
MATERIALS AND METHODS: A single-center retrospective study of 54 patients with inoperable perihilar cholangiocarcinoma who underwent percutaneous transhepatic biliary stent placement between January 1, 2019, and August 31, 2021, was conducted. According to stent location, the patients were classified into 2 groups: suprapapillary (S) and transpapillary (T). Demographic data, Bismuth-Corlette classification, type and location of the stent, laboratory data, postprocedural AEs, procedural success, stent occlusion, reintervention rate, and mortality were compared between the groups.
RESULTS: Stent placement was suprapapillary in 13 (24.1%) patients and transpapillary in 41 (75.9%) patients. Mean age was higher in Group T (78 vs 70.5 years; P = .046). Stent occlusion rates were similar in the 2 groups (Group S, 23.8%; Group T, 19.5%), as were AE rates, the most common being cholangitis (Group S, 23.1%; Group T, 24.4%). There were no significant differences in revision rate (Group S, 7.7%; Group T, 12.2%) and 30-day mortality rate (Group S, 15.4%; Group T, 19.5%). Ninety-day mortality rate was statistically significantly higher in Group T (46.3% vs 15.4%; P = .046). Preprocedural bilirubin level was higher in Group T, as were postprocedural leukocyte and C-reactive protein (CRP) levels.
CONCLUSIONS: Suprapapillary and transpapillary stent placement procedures were similar in terms of procedural success, occlusion rate, revision rate, postprocedural AEs, and 30-day mortality. Ninety-day mortality rate and postprocedural leukocyte and CRP levels were higher in Group T, although these patients were also older and had higher preprocedural bilirubin levels.
