Abstract
INTRODUCTION: True left-sided gallbladder (LSG) is a rare finding that may present with symptoms similar to those of a normally positioned gallbladder. Moreover, it may be missed by preoperative imaging studies such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), or endoscopic ultrasound. True left-sided gallbladder is a surgical challenge and surgical technique may need to be modified for the completion of laparoscopic cholecystectomy.
PRESENTATION OF CASE: In this case report, we present a case of true left-sided gallbladder that produced right-sided abdominal symptoms. Ultrasound of the abdomen failed to show the left-sided position of the gallbladder. MRI showed the gallbladder located to the left of the ligamentum teres underneath segment III of the liver. Intraoperatively, the gallbladder was grasped and retracted to the right under the falciform ligament and it was removed using classical right-sided ports with no modification to the technique. No complications were encountered intraoperatively or postoperatively.
DISCUSSION: True LSG is a rare anomaly that may present with right-sided symptoms like normally positioned gallbladder. It may be missed in preoperative imaging studies and can be discovered only intraoperatively. Modification of laparoscopic ports, change in patient's position and/or surgeon's position, or conversion to open cholecystectomy may be needed for safe removal of the gallbladder.
CONCLUSION: Classical technique of laparoscopic cholecystectomy is feasible for left-sided gallbladder. However, if the anatomy is not clear, modifications of the surgical technique may be necessary for the safe dissection of the gallbladder.
