IMAGING TO GUIDE CHOLECYSTECTOMIES

Discover the clinical benefits of active imaging with intraoperative ultrasound for laparoscopic cholecystectomy procedures. Using bkActiv and the Advanced Laparoscopic Transducer, surgeons can visualize anatomy and monitor progress as many times as needed during the procedure.

Watch this video to see how it works.

THE VALUE OF iUS IN CHOLECYSTECTOMIES

iUS is beneficial for cholecystectomies due to its safety, quick and repeatable imaging capabilities and ability to detect choledocholithiasis and enable visualization of biliary tract anatomy.

SAFETY

SAFETY

iUS has minimal safety risks as it is non-irradiating and does not required cannulation .1-3

QUICK, REPEATABLE IMAGING

QUICK, REPEATABLE IMAGING

iUS can be used dynamically throughout dissection adding minimal time to a cholecystectomy procedure. iUS can also repeated, helping to assess common bile duct integrity at the end of the procedure.1-5

CHOLEDOCHOLITHIASIS DETECTION

CHOLEDOCHOLITHIASIS DETECTION

iUS helps differentiate between sludge, stone, polyps, cysts, and tumors when determining if there is a presence of gallstones in the common bile duct.5.6

BILIARY TRACT VISUALIZATION

BILIARY TRACT VISUALIZATION

iUS uses color flow doppler to help differentiate between vessels and ducts and is overall effective at imaging difficult cases such as inflammation or fibrosis .1.4 - 6

When helping to detect choledocholithiasis, iUS resulted in a 90-96% sensitivity rate and 100% specificity rate.7

iUS is highly effective in visualizing biliary anatomy, which can be abnormal in as high as 40% of patient cases.8

Gallbladder Adenocarcinoma with Gallstones and Sludge

Bile Duct – Metastatic Tumor With Color Doppler

iUS is comparable to intraoperative cholangiography for imaging cholecystectomies.9

IMAGES FROM A CASE

CASE STUDY

This case study walks through the steps of using intraoperative ultrasound in a laparoscopic cholecystectomy procedure performed by Mr. Somaiah Aroori, MB BS, MS (Surg), FRCS (Gen Surg), a consultant hepatobiliary and renal transplant surgeon at Derriford Hospital and University Hospital Plymouth in the UK. Throughout the procedure, bkActiv provided real-time information that cannot otherwise be obtained from preoperative imaging.

ADVANCED LAPAROSCOPIC TRANSDUCER I13C3f Provides high-resolution imaging for clear visualization of anatomy, with 4-way flexible tip allowing good organ contact and access to difficult-to-reach areas, a laser feature ideal for visualizing needle trajectory, and specially designed needle guidance channels.
