Effect of oral erythromycin on gastric and small bowel transit time of capsule endoscopy

Figure 1 Changes in gastric transit time in patients undergoing repeated capsule endoscopy. Four patients had repeat capsule endoscopy examinations. Two patients (CSK and LMZ), as shown by the black lines, received only erythromycin on the second examination and there was a marked reduction in gastric transit time in the second examination after the use of oral erythromycin. The other patients (WT and MPH), as illustrated by the dotted lines, received erythromycin in both examinations and the gastric emptying time was less than 50 min in both examinations.
