Screening pre-bariatric surgery patients for esophageal disease with esophageal capsule endoscopy

Figure 1 Comparison of esophageal capsule endoscopy vs esophagogastroduodenoscopy. Image of a hiatal hernia on esophageal capsule endoscopy (ECE, panel A) vs esophagogastroduodenoscopy (EGD, panel B). ECE was able to correctly abnormal findings in the esophagus such as hiatal hernias when compared to EGD.

Figure 2 Inter-observer agreement between esophageal and gastric findings and results of esophageal findings on capsule vs esophagogastroduodenoscopy. A: There was a trend toward agreement among esophageal capsule endoscopy and esophagogastroduodenoscopy findings in the esophagus vs stomach (35/40 findings in agreement in the esophagus vs 30/40 findings in agreement in the stomach); B: There was no significant difference between esophageal capsule endoscopy and esophagogastroduodenoscopy (EGD) (P = 0.64) for combined esophageal and gastroesophageal junction findings on 2-tailed Fischer exact test (P = 0.66).
