Robotic Heller-Dor procedure for oesophageal achalasia: Fluorescence-guided intraoperative assessment of myotomy. A retrospective single-centre experience
INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY(2022)
摘要
Background The robotic Heller-Dor (RHD) procedure for oesophageal achalasia (EA) is safe and effective. We aim to evaluate the intraoperative use of fluorescence imaging, as an alternative means to intraoperative endoscopy, to assess myotomy at the end of the procedure. Methods Thirty-four patients affected with EA underwent RHD. The myotomy was assessed intraoperatively by endoscopy in group A (17 patients), and by fluorescence imaging in group B (17 patients). Perioperative and long-term results were compared. Results In group A, one mucosal tear was identified during intraoperative endoscopy. In group B, indocyanine green (ICG) helped identify residual muscle fibres in three cases. No perforation of the oesophageal mucosa occurred in group B. Conclusions Fluorescence-imaging improved the identification of residual muscle fibres and made it possible to verify the integrity of the mucosa without the use of intraoperative endoscopy. A significant reduction in operative times has been related to the use of this technique.
