There are no other acceptable alternatives for gallstone removal besides surgery, shock wave fragmentation, or chemical dissolution.
Patients with symptomatic cholelithiasis can be treated with certain medications called oral bile acid litholysis or oral dissolution therapy. This technique is especially effective for dissolving small cholesterol-composed gallstones. Current research indicates that the success rate for oral dissolution treatment is 70–80% with floating stones (those predominantly composed of cholesterol). Approximately 10–20% of patients who receive medication-induced litholysis can have a recurrence within the first two or three years after treatment completion.
Extracorporeal shock wave lithotripsy is a treatment in which shock waves are generated in water by lithotripters (devices that produce the waves). There are several types of lithotripters available for gallbladder removal. One specific lithotripter involves the use of piezoelectric crystals, which allow the shock waves to be accurately focused on a small area to disrupt a stone. This procedure does not generally require analgesia (or anesthesia). Damage to the gallbladder and associated structures (such as the cystic duct) must be present for stone removal after the shock waves break up the stone. Typically, repeated shock wave treatments are necessary to completely remove gallstones. The success rate of the fragmentation of the gallstone and urinary clearance is inversely proportional to stone size and number: patients with a small solitary stone have the best outcome, with high rates of stone clearance (95% are cleared within 12–18 months), while patients with multiple stones are at risk for poor clearance rates. Complications of shock wave lithotripsy include inflammation of the pancreas (pancreatitis) and acute cholecystitis.
A method called contact dissolution of gallstone removal involves direct entry (via a percutaneous transhepatic catheter) of a chemical solvent (such as methyl tertiary-butyl ether, MTBE). MTBE is rapidly removed unchanged from the body via the respiratory system (exhaled air). Side effects in persons receiving contact dissolution therapy include foul-smelling breath, dyspnea (difficulty breathing), vomiting, and drowsiness. Treatment with MTBE can be successful in treating cholesterol gallstones regardless of the number and size of stones. Studies indicate that the success rate for dissolution is well over 95% in persons who receive direct chemical infusions that can last five to 12 hours.
