AUSTIN, TX – Level-of-care ultrasound (POCUS) isn’t usually used for imaging the pancreas, however maybe that ought to change, in accordance with a presentation given April 7 at UltraCon.
In her discuss, Alice Lee, MD, from Stanford College in California highlighted findings on how POCUS generally is a dependable software for pancreatic imaging, whether or not carried out by skilled or novice sonographers.
“One of many large implications of pancreatic POCUS is the best way that we put imaging within the palms of a supplier who’s actually managing the affected person, whether or not it’s the gastroenterologist or the first care doctor,” Lee mentioned.

POCUS has gained traction and recognition within the twenty first century for its comfort, versatility, and cost-effectiveness, nevertheless it isn’t extensively used for imaging of the pancreas.
“Within the U.S., we’ve form of pooh-poohed this concept of ultrasound for the pancreas with the bile gasoline, weight problems, and it being a retroperitoneal organ,” Lee mentioned. “However we’ve discovered by colleagues in different components of the world that there are areas the place … some international locations in Asia do use ultrasound for primary first-line imaging for the whole lot, together with the pancreas. There are research that present that in doing that, they [physicians] are capable of catch pancreatic most cancers earlier.”
Lee steered that operator dependency and limitations of present ultrasound expertise might contribute to the shortage of utilization within the U.S.
In a pilot research, Lee and colleagues examined the feasibility of POCUS in pancreatic imaging. They included information from 40 sufferers with a mean age of 61.3 years inside Stanford Hospital’s benign pancreas clinic and endoscopy unit.
Two physicians operated the POCUS exams. One was a radiologist with greater than 5 years of ultrasound expertise who was blinded to scientific information. The opposite was a gastroenterologist with 4 hours of ultrasound coaching who was not blinded to the scientific information. Each physicians carried out unbiased bedside POCUS exams and documented visibility and examination size. The researchers in contrast the findings to latest CT, MRI, and/or endoscopic ultrasound exams.
The crew reported that the physicians obtained full or partial photographs in most exams, though the radiologist confirmed superior efficiency. The physicians struggled with imaging the tail space of the pancreas.

|---|---|---|---|---|
| Radiologist | Gastroenterologist | |||
| Pancreatic space | Full or partial photographs | None | Full or partial photographs | None |
| Head | 38 | 2 | 34 | 6 |
| Physique | 40 | 0 | 32 | 8 |
| Tail | 27 | 13 | 15 | 25 |
Moreover, they’d comparable examination instances, together with 4 minutes for the radiologist and 5 minutes for the gastroenterologist.
In contrast with different imaging modalities, POCUS as carried out by the radiologist decided regular pancreatic findings in all instances. Moreover, it precisely visualized 75% of cysts and much 1 cm or bigger and 75% of dilated pancreatic ducts as discovered on CT, MRI, and/or endoscopic ultrasound.
Nonetheless, POCUS struggled with discovering smaller cysts and much, parenchymal atrophy, hyperechoic stranding, and lobularity.
Lee mentioned that with these findings in thoughts and regardless of the rudimentary nature of the exams, the way forward for pancreatic POCUS is promising.
A method that clinics in Asia make use of to assist enhance visualization is having sufferers drink room-temperature or heat distilled water to create extra distinction between the pancreas and abdomen, in accordance with Lee. She added that distinction enhancement and quantitative ultrasound tissue characterization might additionally enhance visibility by POCUS.
“We additionally suppose there are promising implications for instructing given Doctor B’s (gastroenterologist) outcomes,” she mentioned. “Doctor B did an honest job regardless of solely 4 hours of remedy.”
Lee mentioned that the following steps embrace exploring how liquid ingestion, distinction enhancement, and quantitative ultrasound characterization can additional visualize pancreatic findings.
