Currently, the most common treatments for a Zenker's diverticulum include conservative management, open surgical diverticulectomy (OSD) with CP myotomy, and stapler-assisted endoscopic diverticulectomy (SAED) with CP myotomy that was first reported by Collard et al.
The gold standard treatment is myotomy; other therapeutic options include balloon dilatation or botulinum toxin injection.
Surgical management is based on disrupting LES by myotomy. The technique was initially described in 1913 by Ernst Heller (4).

Open surgery was done in the form of diverticulectomy and cricopharyngeal muscle myotomy through a lateral cervical approach.
Crural fibers and vagus nerve were identified before commencement of myotomy.
Robotically assisted Heller myotomy is emerging as a safe alternative to the laparoscopic approach.
With the ability to advance the boundaries of minimally invasive surgery and laparo-endoscopic single site surgery in procedures such as Choleystectomy (gallbladder removal), Hysterectomy (removal of uterus), Nephrectomy (kidney resection), Heller Myotomy (procedure for Achalasia) and more, the laparoscope features:
The laparoscopic Heller myotomy involves cutting the LES muscle, making it incompetent and allowing food boluses to pass through the LES.
A reduction in LOS pressure can be achieved by disrupting the LOS muscle fibres by generating a radial force from within the oesophageal lumen (by pneumatic dilation), by cutting the muscle fibres (as in myotomy) or by poisoning them with botulinum toxin (BTox).
