A patient with acute obscure gastrointestinal bleeding was found to have a large amount of food retention in the stomach after fasting for >12 hours. We tried to adjust the patient's body position to facilitate capsule endoscopic examination. The patient laid on the bed on his right side, which is the position required for a normal procedure, and then his hip was raised while his upper body was lowered gradually until the pylorus appeared at the center of the screen of the real-time monitor. It took 15 minutes of body position adjustment to make the pylorus appear at the center of the monitor and another 5 minutes for the capsule endoscope to enter the duodenum. The lesion was ultimately found at the terminal small intestine.
