Peroral endoscopic myotomy of a suspected type III achalasia with a double scope control
A 59-year-old woman was referred to our unit for progressive dysphagia and chest pain associated with heartburn and chest fullness. A nutcracker esophagus was suspected at the HD manometry and the patient was scheduled for a peroral endoscopic myotomy (POEM). The procedure started with an esophagogastroduodenal series (EGDS), which showed abnormal contractions of the distal esophagus and increased resistance at the level of the esophagogastric junction (EGJ) with a high suspicion of type III achalasia. The tunnel was started 12cm above the EGJ in a 5 o’clock position. After submucosal injection, a mucosal incision was made with a new triangle-tip (TT) knife equipped with water jet facility. The access to the submucosa was gained and a submucosal longitudinal tunnel was created until the EGJ, dissecting the submucosal fibers with the TT knife. The myotomy was performed by completely dissecting the circular muscular layer muscle fibers using swift coagulation. To assess the extension of the myotomy just at the level of the EGJ, a “double scope control” was performed by inserting a pediatric scope, which confirmed the presence of the mother scope light in the esophagus. The submucosal tunnel and the myotomy were then extended together for 1 to 2cm. A second check with the pediatric scope showed the presence of the mother scope light in the correct position above the EGJ. The mucosal incision site was finally closed using multiple endoclips.

LIVE INTERACTIVE SURGERY: POEM for type 2 achalasia and incidental esophageal leiomyoma
POEM (peroral endoscopic myotomy) is an emerging procedure, which has evolved from the era of NOTES. The most cardinal indication for POEM is achalasia of the cardia. Other indications include diffuse esophageal spasm, jackhammer esophagus, and surgically failed cases.
The steps of POEM include the following: mucosotomy, submucous tunnelling, myotomy, closure of mucosotomy.
The myotomy is started 2 to 3cm distal to the mucosotomy and is continued to the end of the tunnel at 2 to 3cm distally to the gastroesophageal junction (GEJ). A partial myotomy is most commonly performed by means of careful dissection of circular fibers, hence avoiding longitudinal fibers to prevent entry into the mediastinum. The mucosotomy is then closed to prevent any leakage with the use of endoscopic clips or of an endoscopic suturing device. About the EndoFLIP™ (Endolumenal Functional Lumen Imaging Probe) Imaging System: this is a functional endoluminal imaging probe, which helps in the assessment of gastroesophageal junction distensibility and compliance after the procedure.
Complications of POEM:
Inadvertent mucosotomy is the most common complication.
Complications due to insufflation (pneumomediastinum, pneumoperitoneum) can be controlled by using carbon dioxide for insufflation. Esophageal leak is the most dreaded complication with rates ranging from 0 to 5.6%.
