| Summary: | Mechanical, intracorporeal and extracorporeal lithotripsy were
used in the treatment of common bile duct lithiasis in a series of 80 patients in
whom initial extraction attempts with the Dormia basket and balloon catheter
failed. Mechanical lithotripsy was performed in 74 cases and was successful in 38
(51.3%). Among the 36 patients with failure of mechanical lithotripsy, five had
an initial attempt at stone dissolution w1th methyl terr-butyl ether (MTBE)
infused through a nasobiliary stent. This was successful in four cases; the stones
did not disappear completely - however, they were smaller and easier to extract.
Of the remaining 32 patients who failed mechanical lithotripsy, two underwent
success[, l surgical stone extraction with no further attempts at nonoperative
treatment and 30 underwent complementary shock wave lithotripsy. Extracorporeal
lithotripsy was used in 19 of these patients. The intracorporeal lithotripsy
group of21 patients comprised 11 with failed mechanical lithotripsy, six in whom
no ocher treatment was attempted and four in whom extracorporeal lithotripsy
had failed. Extracorporeal lithotripsy was successful in 15 cases (79%) and
intracorporeal lithotripsy in 19 (90%). There were four treatment failures, with
one patient death due to cholangitis and respiratory failure. In summary,
mechanical lithotripsy is an effective and safe treatment modality but has a high
failure rate. Extracorporeal lithotripsy is useful and should he attempted where
available, but is not always successful. Intracorporeal lithotripsy is very efficient
but requires either the transpapillary route, which is technically difficult, or the
transhepatic route which carries associated complications. |
