Effect of short-term indomethacin treatment on the clinical course of acute obstructive cholecystitis.

In acute obstructive cholecystitis the increased intraluminal pressure in the gallbladder is reduced by nonsteroid anti-inflammatory drugs which effectively relieve biliary pain. To investigate if such drugs influence the clinical course, a double-blind study was performed in which indomethacin (suppositories 75 mg b.d.) was tested against placebo in 34 patients with acute obstructive cholecystitis. During the 3-day treatment period both the indomethacin and the placebo group improved significantly as regards pyrexia, pain, abdominal tenderness and leukocytosis. The indomethacin group showed significantly greater improvement than the placebo group in temperature, pain and white blood cell count on day 1, and significantly greater reduction of abdominal tenderness on day 2. The serum bilirubin fell significantly during the 3-day period in the indomethacin, but not the placebo group. The hospital stay in cases without early surgery was significantly shorter in the indomethacin group (5.4 vs. 8.5 days). Because of its favourable effect on the clinical course of acute cholecystitis, rectally administered indomethacin is useful for patients awaiting operation or scheduled for later elective surgery.
