Do orogastric tubes improve transesophageal echocardiographic imaging during cardiac surgery : a randomized trial?
While this study was underpowered to detect small changes in image quality, the use of an OG tube for routine cases did not improve the overall quality of the related images acquired during TEE examination.
Based on the results of this retrospective study, no evidence indicates that oncologic control is compromised for patients treated with LRN in comparison with ORN.
