[Simultaneous laparoscopic treatment for common bile duct stones associated with acute cholecystitis. Results of a prospective study].
Laparoscopy for the management of acute cholecystitis has gained wide acceptance. Although it is well known that acute cholecystitis may be complicated by common bile duct stones in up to 15% of cases, to date there are no published studies addressing the management of common bile duct stones detected during laparoscopy for acute cholecystitis. We postulated that, when found, common bile duct stones associated with acute cholecystitis could be effectively and safety managed during the same laparoscopic procedure. We report on a five-year prospective study (2001-2005) involving 313 unselected patients who presented with a clinical diagnosis of acute cholecystitis (confirmed by specimen examination) and without any contraindication to laparoscopy. At surgery, transcystic cholangiograms were obtained in 289 (92%); the other 24 were excluded from the study. With an established diagnosis of common bile duct stones, attempts were made to clear the common bile duct by transcystic basket retrieval, ERCP or choledochotomy. Prevalence of common bile duct stones in acute cholecystitis, success of laparoscopic common duct clearance, conversion rate, operative time, morbidity, and postoperative hospital stay were the main outcome measures. Common bile duct stones were found in 63 pts (21.7%) presenting with acute cholecystitis. At laparoscopy, 12 patients (19%) required conversion to open surgery, 3 of these being due to failure to achieve common bile duct clearance. Common bile duct stones were cleared entirely laparoscopically in 51 patients (81%) by means of transcystic stone retrieval (38 pts, 75%), ERCP (12 pts, 23%) or choledocotomy (1 pt, 2%). At intention to treat analysis, patients undergoing cholecystectomy plus common bile duct clearance compared to those undergoing cholecystectomy alone, spent significantly more time in the operating theatre (mean 192 min vs 118 min, p < 0.001), needed open conversion more frequently (19% vs 6.1%, p = 0.0045), and had a higher overall morbidity rate (17.4% vs 4.4%, p = 0.015). The simultaneous procedure also adversely affected the postoperative hospital stay (mean 4.8 vs 3.4 days, p = 0.0164). Mortality was nil in both groups. The prevalence of common bile duct stones in patients presenting with acute cholecystitis should not be neglected. When common bile duct stones are found, clearance may be obtained laparoscopically in a substantial number of cases without any need for open surgery. The simultaneous laparoscopic approach for acute cholecystitis and common bile duct stones remains, however, a highly skilled and technically demanding procedure. Although a moderate incidence of drawbacks is observed, the results should be interpreted from the point of view of an all-in-one procedure that allows the patients to be cured without needing any further sequential interventions.
