The surgical argument
Why not POEM
•Invasive ?
•Not effective
•Side effects
•Cost
Efficacy of peroral endoscopic myotomy (POEM) in the treatment of
achalasia cardia: A systematic review and metaanalysis
Talukdar R, Inoue H, Reddy DN. Surgical Endoscopy 2014
Eckhart’s score
Post-operative pain
How POEM is different from LHM?
Can be done in Endoscopy room
Equipment required
•Standard upper GI scope
•Transparent tapered cap
•CO2 insufflator
•Triangular tip knife
•Electrical generator ERBE 300D
•Sub mucosal solution – NS+ 0.3%
indigo carmine
•Injection needles, hemoclips
Full control on extent of myotomy
• Only the circular muscle layer of the esophagus
is divided
• Length of myotomy can be extended in
esophagus
Preservation of Phreno-Oesophageal membrane
• The hiatus is not mobilized
• Vagus nerve is not mobilized
• An antireflux procedure is not performed
GERD after POEM
Subjective data (GERD symptom score)
• No GERD symptoms 68%
• Minimal (few times/month) 16%
• Moderate (few times/week) 13%
• Severe (daily) 3%
Stavropoulos et al , Ther Adv Gastroenterol 2013
GERD not as low as initially reported but similar to rate reported in high
quality studies post LHM+Dorfundoplication
