Subparietal hepaticojejunal access loop for the long-term management of intrahepatic stones

The subparietal hepaticojejunal biliary access loop is a recognized technique for the long-term management of primary intrahepatic stone disease. This paper assesses the results of this approach in a series of South African patients.

Between 1985 and 1997, 21 patients, of mean age 34 (range 24-66) years, underwent surgical extraction of intrahepatic stones and formation of an hepaticojejunal access loop. The access loop was subsequently used for further stone removal and stricture dilatation. Patients were followed prospectively (median 47 months) and details of the number and type of procedures performed, stone clearance rates, morbidity and subsequent outcome were recorded.

The distribution of intrahepatic stones was left lobe in 13 of 21 patients, right lobe in one and bilateral in seven. Six patients underwent additional left lobectomy at the initial operation because of associated atrophy of the left lobe. Following operation, stone removal and/or stricture dilatation was performed on 97 occasions (median 4 (range 0-24) procedures per patient). Complete stone clearance was achieved in 17 of 21 patients with partial clearance in the remaining four. There were no major complications and no deaths associated with the procedures.

The subparietal access loop permits long-term access to the intrahepatic ducts allowing removal of stones and dilatation of strictures with minimal patient discomfort and low morbidity.
