Submucosal Surgery: Pyloromyotomy and Tumor Enucleation

  • Eran Shlomovitz
  • Oscar M. Crespin


Spurred by advances in endoscopic imaging, instrumentation, and energy devices, therapeutic endoscopic techniques such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have gained popularity and mainstream acceptance. Experience gained with these procedures in combination with the interest in natural orifice transluminal endoscopic surgery (NOTES) led to the development of the peroral endoscopic myotomy (POEM) procedure. The POEM procedure for the treatment of achalasia and other spastic esophageal disorder has quickly become the most successful and widely adopted NOTES procedure. The worldwide acceptance of POEM stimulated endoscopists to expand the techniques of operating in the submucosal space. In this chapter we aim to describe the techniques of endoscopic submucosal tumor enucleation, peroral pyloromyotomy (POP), as well as future trends in the field.
