Effectiveness of a new approach to minimally invasive surgery in palliative treatment of patients with distal malignant biliary obstruction

Figure 3 Kaplan-Meier cumulative survival curves for patients with distal malignant biliary obstruction who underwent various minimally invasive palliative procedures. Patients with internal-external biliary-jejunal drainage had a higher survival rate than the other groups (P < 0.05). DMBO: Distal malignant biliary obstruction; ERBS: Endoscopic retrograde biliary stenting; IEBJD: Internal-external biliary-jejunal drainage; IETBD: Internal-external transpapillary biliary drainage; PTBD: Percutaneous transhepatic biliary drainage.
