Background/Aims: Both endoscopic nasobiliary drainage (ENBD) and a plastic stent placement have some limitations in biliary decompression of elderly patients with acute cholangitis of severe type (ACST) due to choledocholithiasis. Dual stent placement may improve bile drainage without obvious discomfort. Here, we evaluated its advantages in the biliary decompression of elderly patients with ACST. Materials and Methods: A total of 257 elderly patients (≥65 years) with ACST had undergone urgent endoscopic decompression by nasobiliary catheter (ENBD group), single plastic stent (single-stent group), or dual plastic stents (dual-stent group). The data of the three groups was compared retrospectively. Results: The demographic data of the patients in the three groups were comparable. After endoscopic decompression, the serum total bilirubin and γ-glutamyl transferase levels in the dual-stent group were decreased faster than that in the single-stent group (P < .05). The abdominal pain in the dual-stent group was dramatically slighter than that in the ENBD group (P < .05). Compared with two other groups, the acute physiology and chronic health evaluation II scores were decreased dramatically quicker (P < .05) and the length of intensive care unit stay was significantly shorter (P < .05) in the dual-stent group. In the second endoscopic retrograde cholangiopancreatography, the rate of complete stone clearance in the dual-stent group was significantly higher than that in the ENBD group (P < .05). Conclusions: Dual-stent placement might be a better choice for elderly patients with ACST due to choledocholithiasis in comparison with ENBD or a single-stent placement.
