Objective: To investigate the diagnostic value of capsule endoscopy in recumbent position and upright position for esophageal lesions in the elderly.
Methods: Clinical data of 180 elderly patients undergoing magnetic control capsule endoscopy (MCCE) in the digestive endoscopy center of our hospital were retrospectively analyzed. Statistical analysis was made on time for MCCE to pass through esophagus, dentate line visibility, esophageal lesion detection rate and safety under capsule endoscopy in recumbent position and upright position. Comparison was made on the diagnostic value and safety of capsule endoscopy in the two positions for esophageal lesions.
Results: The time for MCCE to pass through the esophagus was significantly higher in the recumbent position group than in the upright position group (87.1±6.62 seconds vs. 16.15±4.66, P<0.005). The dentate line detection rate was significantly higher in the recumbent position group than in the upright position group (62.2% vs 33.3%, P<0.001). The positive lesion detection rate was superior in the recumbent position group compared with the upright position group (37% vs 12%, P = 0.001). All examinees had no capsule retention.
Conclusion: The recumbent position group has higher detection rate of esophageal lesions than the upright position group. The result can be extended to capsule endoscopy of general population, which is beneficial to improve the detection rate of esophageal lesions.
