Percutaneous extraction of retained gallstones via the T-tube track-British experience of 131 cases.

Twenty-six hospitals replied to a questionnaire asking for experience in the technique for percutaneous extraction of retained gallstones via the T-tube track. One hundred and thirty-one patients were treated. The overall success rate (complete clearance of residual stones) was 70% and a marked improvement in success rates with increasing operator experience has been demonstrated. The complication rate remains acceptably low during the learning phase. There was no mortality. There were 12 complications (9.2%): pancreatitis (one case), fever (seven cases) and track perforation (four cases). One patient required surgery for complication (track perforation). Variations in technique and management are described.
