Ultrasound was made for the diagnosis of small bowel obstruction. It loves when air filled things are turned into fluid filled things - its helps us see it better. When the bowel gets backed up and distends with digested cheeseburgers, ultrasound is there to save the day. As easy as this may seem, it has not been well studied. There are a few small studies that show it can be accurate compared to a CT, but without a large body of evidence - a lot of people are (quite reasonably) unwilling to put their faith in it. Well, we can't say this study is going to turn all that around, but its one more piece of the puzzle of figuring out how we can use POCUS for this diagnosis.
