ABSTRACT
Objective To investigate the use of laparoscopic ultrasound to exclude cystic duct obstruction and its related risk factors in laparoscopic cholecystectomy.Methods The data of 28 patients who underwent laparoscopic cholecystectomy in our department for cystic duct obstruction from February 2008 to April 2010 were analyzed.Subtotal resection of gallbladder and exclusion of cysticduct were carried out when the gallbladder triangle anatomy was not clear.An abdominal drain was used.Results All the patients were cured and there was no bleeding,abdominal infection,or jaundice.On univariate analysis,risk factors for cystic duct obstruction were adhesions in Calot triangle,gallbladder atrophy,acute cholecystitis,cystic duct stone incarceration,gallbladder wall thickening and white bile.Adhesion in Calot triangle,acute cholecystitis and white bile were independent risk factors on multivariate analysis.Conclusion Excluding cystic duct obstruction by laparoscopic ultrasound for patients who underwent laparoscopic cholecystectomy for cystic duct obstruction is safe and effective.
