Adjunctive choledochoduodenostomy to choledocholithotomy in the treatment of calculous biliary tract disease.

Between 1986 and 1991, 16 selected patients with calculous biliary tract disease (CBTD) underwent side-to-side choledochoduodenostomy (CDS) as an adjunct to either primary (10 patients) or secondary (six patients) choledocholithotomy. Patients selected for adjunctive CDS were those with common bile duct dilatation > or = 1.5 cm in size. All operations were elective procedures. The stoma of the CDS was about 3.0 cm in size, measured directly. There were no operative deaths. There were no early complications related to the CDS procedure itself, except for two (12.5%) wound infections. CDS significantly eliminates bile stasis which is indicated by a fall in both the serum levels of alkaline phosphatase (from 228 +/- 118 to 72 +/- 22 IU/L, p < 0.01) and total bilirubin (from 4.7 +/- 4.7 to 0.9 +/- 0.2 mg/dL, p < 0.01) postoperatively. Late complications (ascending cholangitis or sump syndrome) of CDS or recurrent symptoms of CBTD were not encountered during the average follow-up period of 21 +/- 18 months. From our clinical results, we suggest that adjunctive CDS to choledocholithotomy is a safe and effective procedure in the treatment of selected patients with CBTD.
