title: Laparoscopic diagnosis of gallbladder agenesis.
abstract: In this article, we report two cases of gallbladder agenesis that were incorrectly diagnosed as cholelithiasis on preoperative sonography. In the first case, the diagnosis was made by laparoscopic surgery and confirmed by postoperative CT scan. The second case was confirmed by laparoscopic abdominal examination and by laparoscopic sonography. Both patients had undergone preoperative IV cholangiography. Preoperative cholangiography and laparoscopic exploration completed by laparoscopic sonography should be considered adequate modalities for the diagnosis of gallbladder agenesis, without the need for laparotomy and thorough postoperative workup.
