Feasibility Study of Single-Port Laparoscopic Techniques for Pancreatic Exploration, Ultrasound, and Biopsy in Dogs

Blog Article

This study aimed to evaluate the feasibility of single-port laparoscopic pancreatic exploration, laparoscopic ultrasonography, and pancreatic biopsy in dogs.Six clinically healthy Beagles (median age: 13 months; range: 12–30 months; median weight: 8.81 kg; Interface Card range: 7.82–10.64 kg) with normal findings upon physical examination and no history of systemic disease underwent a single-port laparoscopic procedure via a paramedian incision.

In all cases, pancreatic exploration was performed visually through laparoscopy but was limited to the right lobe and body of the pancreas due to anatomical constraints; the left lobe remained inaccessible.The median exploration time was 239 s for the right lobe and 370 s for the pancreatic body.After exploration, a laparoscopic ultrasound was performed on the parenchyma of the explored regions, successfully identifying major anatomical structures, including the cranial Bike Parts - Derailleurs - Front pancreaticoduodenal artery, vein, and major duodenal papilla.The median laparoscopic ultrasound evaluation time was 838 s (range: 729–878 s).A pancreatic biopsy was performed on the distal portion of the right lobe, yielding tissue samples of approximately 10 × 10 mm in size.

No intra- or postoperative complications were observed.However, this study was conducted in healthy dogs; further validation is necessary to confirm its diagnostic utility.These findings demonstrate the feasibility of single-port laparoscopic exploration and laparoscopic ultrasonography-guided anatomical assessment.
