Laparoscopic Ultrasound and Safe Navigation Around the Shrunken Gallbladder

A Navigation System for Augmenting Laparoscopic Ultrasound

Establishing image context is the major difficulty of performing laparoscopic ultrasound. The standard techniques used by transabdominal ultrasonographers to understand image orientation are difficult to apply with laparoscopic instruments. In this paper, we describe a navigation system that displays the position and orientation of laparoscopic ultrasound images to the operating surgeon in real...

Ultrasound imaging of the gallbladder

Reformed gallbladder after laparoscopic subtotal cholecystectomy: correlation of surgical findings with ultrasound and CT imaging†

Laparoscopic subtotal cholecystectomy is a technique that is becoming increasingly prevalent in modern surgery. It avoids the cystic duct and artery where acute or chronic cholecystitis prevents a safe laparoscopic dissection of these structures. There are numerous reports of symptomatic cystic duct remnants after subtotal cholecystectomy in the literature on post-cholecystectomy syndrome. We p...

Septate gallbladder in the laparoscopic era

The anatomy facing a surgeon during cholecystectomy is challenging as it involves complex relationship between the gallbladder, hepatic artery and extra-hepatic billiary tree. We report a case of septate gall bladder which was successfully treated with laparoscopic cholecystectomy. In this paper, we also discuss the embryology and characteristics of this rare anomaly. Lack of awareness, non-spe...

Laparoscopic Derotation and Cholecystectomy for Torsion Gallbladder

Torsion of the gallbladder is an unusual cause of gangrenous cholecystitis. Even with the advent of recent radiological imaging modalities, the preoperative diagnosis of this entity remains elusive. Herein, we present a case of gallbladder torsion in a 76-year-old lady who successfully underwent laparoscopic derotation and cholecystectomy.
