Zusammenfassung: | To compare the survival prognosis of percutaneous transhepatic biliary stenting (PTBS) in the treatment of malignant obstructive jaundice (MOJ) at different horizontal sites.
A total of 120 patients with MOJ who underwent biliary stenting were retrospectively included and analyzed and divided into the high-position group (36 patients), middle-position group (43 patients), and low-position group (41 patients) according to biliary obstruction plane by biliary anatomy. Kaplan-Meier curves were used to test for differences in the overall survival (OS), risk assessment of death and potential risk factors for 1-year survival were analyzed using multifactorial Cox regression.
The median survival of the high-, middle-, low-position groups were 16, 8.6, and 5.6 months, with a statistically significant difference (P = 0.017). The 1-year survival rate was 67.6%, 41.9%, and 41.5% in the high-, middle-, low-position groups (P < 0.05), and the 1-year risk of death was 2.35 and 2.93 times higher in the medium- and low-position groups, respectively. The incidences of the main complications were 25%, 48.8%, and 65.9% in the high-, middle-, and low-position groups, respectively, (P = 0.002). While the differences in median stent patency were not statistically significant (P > 0.05) in the groups, alanine transaminase, aspartate transaminase, and total bilirubin levels decreased gradually in each group at 1 month and 3 months after interventional therapy (P < 0.001), while there was no significant difference in the decrease between the groups.
Different levels of biliary obstruction in patients with MOJ affect survival, especially at 1 year, where high obstruction treated with PTBS has a low incidence of complications and a low risk of death. |
