CHOLEDOCHOLITHIASIS-Correlation of Preoperative with Operative and Postoperative Data to Enhance Diagnostic Insight.

One hundred cases of common bile duct explorations were reviewed in an attempt to obtain information that might give insight into the diagnosis and definitive treatment of choledocholithiasis. Fifty of the hundred patients had common duct stones. Correlations were made between the incidence of choledocholithiasis as proved at operation, and the following factors: Kind and number of choledochal exploratory criteria used, the clinical diagnosis of common duct stones, and the pathologic features of gallbladders removed. The incidence of stones was statistically related to aging. The most frequent choledochal exploratory criteria were common duct dilatation or thickening (63 cases) and history of jaundice (50 cases). The most reliable single criterion in "diagnosing" common duct stones was palpable common or hepatic duct stones, the diagnosis having been correct in 15 of 17 such cases. The most reliable combination of criteria was a history of jaundice, plus palpable stones, with correct diagnosis in all such cases. The clinical diagnosis of choledocholithiasis was correct in only 17 per cent of cases. The correlation of the incidence of common duct stones with the degree of gallbladder disease-that is, acute or chronic-did not provide information that might be helpful in diagnosing choledocholithiasis. The incidence of proven retained common duct stones was 3 per cent, the non-fatal postoperative complication rate was 21 per cent and operative mortality was 1 per cent.
