title: Eus combined with ESD or EMR for the diagnosis and treatment of protruding gastrointestinal lesions.
abstract: OBJECTIVE
  To investigate the use of endoscopic ultrasound combined with endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) for the diagnosis and treatment of protruding gastrointestinal lesions.
  
  
  METHODS
  Endoscopic and clinicopathological data were available for 158 patients with protruding gastrointestinal lesions who underwent endoscopic ultrasound. We selected for ESD or EMR treatment 138 patients with gastrointestinal protruding lesions that did not reach the muscular layer of the mucosa according to their endoscopic ultrasound findings. We compared the consistency of the diagnoses made with normal gastrocoloscopy, endoscopic ultrasound, and pathology after the ESD or EMR treatment, and evaluated the therapeutic effects of ESD or EMR on protruding gastrointestinal lesions. We also performed follow-ups with gastrocoloscopy and endoscopic ultrasound one, three, and six months after surgery.
  
  
  RESULTS
  Of 158 patients who underwent endoscopic ultrasound, 138 were treated with ESD or EMR. Postoperative oozing of blood occurred in 12 patients and hemorrhage in four patients, and the complication rate was 2.9% (4/138). There were no serious complications. The pathological diagnoses were consistent their endoscopic ultrasound diagnoses, so the accuracy of endoscopic ultrasound was 97.8% (135/138).
  
  
  CONCLUSIONS
  Endoscopic ultrasound combined with ESD or EMR can improve the diagnosis of protruding gastrointestinal lesions.
