Use real-time near-infrared fluorescence during Heller's cardiomyotomy for achalasia cardia.

Laparoscopic Heller's cardiomyotomy is the surgical procedure of choice in the management of oesophageal achalasia. It is critical to confirm the completeness of the myotomy and mucosal integrity at the conclusion of the procedure. This is conventionally achieved by intraoperative endoscopy and dynamic air leak test. Other modalities that can be used to confirm the myotomy and the integrity of the mucosa at the myotomy site are oesophageal manometry and a methylene blue dye study, respectively. Indocyanine green (ICG) has been in clinical use for more than six decades. The real-time integration of ICG fluorescence with laparoscopy is a relatively new breakthrough. Here, we present a novel method of using real-time near-infrared ICG fluorescence for confirming the completeness of the myotomy and mucosal integrity at the myotomy site post laparoscopic Heller's myotomy. This is the first report on the use of ICG in laparoscopic Heller's cardiomyotomy that we are aware of.
