Aims. To investigate the effect of biliary stent placement without endoscopic sphincterotomy (EST) on common bile duct stones (CBDS) disappearance and the contribution of preserving the duodenal papilla function to reduce recurrence of CBDS.Methods. Sixty-six patients admitted for acute obstructive cholangitis due to CBDS who underwent biliary stent placement without EST for 2 years from March 2011 were evaluated retrospectively. The second endoscopic retrograde cholangiopancreatography (ERCP) was performed for treatment of CBDS 3 to 4 months after the first ERCP. We estimated the rate of stone disappearance at the time of second ERCP.Results. CBDS disappearance was observed in 32 (48.5%) of 66 patients. The diameter of the bile ducts and the diameter of CBDS in patients with CBDS disappearance were significantly smaller than in those with CBDS requiring extraction (p=0.007andp<0.001, resp.). Stone disappearance was evident when the diameter of bile ducts and that of CBDS were <10 and 7 mm, respectively (p=0.002).Conclusions. Short-term stent placement without EST eliminates CBDS while preserving duodenal papilla function and may be suitable for treating CBDS in patients with nondilated bile ducts and small CBDS.

PURPOSE: To evaluate the effects of biliary stenting in rats through analysis of collagen and elastin deposition in the bile ducts. METHODS: Twenty male rats underwent midline laparotomy, duodenotomy and transampullary stenting of the common bile duct with a 22Fr plastic stent. Animals were randomized in 4 groups, with 5 components in each: (I) control, (II) biliary stenting for 7 days, (III) biliary stenting for 14 days, and (IV) biliary stenting for 30 days. Sections of the common bile duct were stained using Hematoxylin Eosin; Sirius Red to quantitate the amount of collagen present; and Weigert's Resorcin-fuchsin to quantitate the amount of elastin present. RESULTS: The percentage of area stained for collagen was 13.4; 21.5; 29.5 and 32.8, for groups I to IV, respectively. The percentage of area stained for elastin fibers was 7.0; 5.2; 4.0 and 2.9, for groups I to IV, respectively. Collagen/Elastin ratio was 2.4; 5.1; 11.0 and 14.4 for groups I to IV, respectively. CONCLUSIONS: The biliary stenting leads to collagen and elastin deposition in the bile ducts; and collagen deposition and collagen/elastin ratio are proportional to the period of stenting.
