title: [Clinical characteristics of impacted bile duct stone in the elderly].
abstract: Acute cholangitis due to impacted bile duct stone is sometimes fatal and require prompt bile duct decompression. Particularly, AOSC (acute obstructive suppurative cholangitis) is the most serious form of bacterial cholangitis and its prognosis is usually very poor when treated conservatively. We have been treated impacted bile duct stones by decompressing the duct endoscopically. Here, we report the characteristics of our elderly patients with impacted bile duct stones who received urgent decompression treatment mainly by endoscopic techniques. In the endoscopical treatment group, the number of patients with AOSC was 5 out of 46 AC (acute cholangitis) patients (11%) under 69 years old, 14 out of 52 (27%) from 70 to 79 years old, and 12 out of 28 (43%) over 80 years old. Obviously, the severity of acute cholangitis (ratio of AOSC to AC) was higher in the elderly. This tendency was similar to the patients who received urgent transhepatic decompression treatment, although they were small in number. In all the patients treated, 7 were classified into the most serious AOSC category with Reynolds' sign, and notably 6 out of 7 were over 70 years old. More strikingly, 5 of 7 patients were over 80, and their mortality rate was indeed high. Thus, in the elderly, bacterial cholangitis by impacted bile stones was a very serious condition. Especially, the outcome of AOSC over 80 years old with Reynolds' sign was very poor, in spite of emergency endoscopic treatment.
