The emergency doctor from the ultrasound room recognized Zheng Ren, since most of his patients were from the emergency department.
He laughed. "Chief Zheng, are you planning to do the B-scan yourself?"
"I know a little," Zheng Ren retrieved the probe from him and moved it around the patient's abdomen to search for the location he wanted, looking closely at the image on the monitor.
There was obstruction at the far end of the bile duct. Zheng Ren switched between two different positions, lateral and anteroposterior, to confirm that the obstructions were not made of dense calculi but rather decomposing, fermented food debris.
The obstruction point matched complications from side-to-side choledochoduodenostomy and disproved the differential diagnoses of Roux-en-Y choledochojejunostomy and choledochoduodenal fistula.
It was apparent that dilation of the bile duct was the leading cause of the patient's obstructive jaundice.
