Impact of 3D-planimetry on Optimized Therapeutic Assessment in Complex Benign Esophageal Stenosis

Impact of 3D-planimetry on Optimized Therapeutic Assessment in Complex Benign Esophageal Stenosis; a Prospective Multi-center Study

Esophageal stenosis has a high impact on patients quality of live and food intake affecting personal nutrition status and general health.

For benign strictures of the esophagus, endoscopic dilatation therapy is recommended by actual guidelines.

Since the extent of dilatation is currently directed by endoscopic view and fluoroscopic imaging, patients are exposed to radiation and the determination of the appropriate extent of dilatation is difficult.

Therefore, the aim of this study is to compare the effect of 3D-planimetric measurement with current fluoroscopic monitoring on the success of endoscopic esophageal dilatation therapy in patients with benign esophageal stenosis.

Inclusion Criteria:

• symptomatic benign esophageal stenosis
• medical indication for endoscopic therapy
• written consent after detailed information

Exclusion Criteria:

• non-benign esophageal stenosis
• missing written consent
• trans-oral endoscopic access is not possible
• medical contraindication for endoscopic dilatation therapy
• age <18 years
