Current status of laparoscopic therapy of cholecystolithiasis and common bile duct stones.

BACKGROUND

Laparoscopic cholecystectomy (LC) is the standard operation for gallstone disease. The aim of this review was to scrutinize the advantages and benefits of this minimal invasive technique compared to the conventional operation according to the available literature. Regarding the evidence-based medicine criteria, the current status of laparoscopy in the treatment of cholecystolithiasis, cholecystitis and common bile duct stones has been worked out.

METHODS

A Medline, PubMed, Cochrane search.

RESULTS

Ten randomized controlled trials (RCTs) are available comparing laparoscopic versus open cholecystectomy. The superiority of LC in less postoperative pain, shorter recovery and hospital stay is stated. Operation time was longer in the first years of LC. 3 RCTs deal with acute cholecystitis: one paper could not find any significant advantage of LC over conventional cholecystectomy, the other two found benefits in recovery, hospital stay and postoperative pain. The range of conversion is between 5 and 7% in elective cases and increases up to 27% for acute cholecystitis. With a rate of more than 90% in Europe, the standard procedure for common bile duct stones is 'therapeutic splitting' with endoscopy and retrograde cholangiopancreatography preoperatively followed by LC. Laparoscopic bile duct clearance is effective and safe in experienced hands, however, the only proven benefit is a slightly shorter hospital stay.

CONCLUSION

The laparoscopic approach is preferred in elective cholecystectomy and acute cholecystitis. The minimal invasive technique has proven to be effective, gentle and safe. The main benefits are evident within the first postoperative days.
