Three cases of cricopharyngeal achalasia are being presented. The preoperative diagnosis was established by a contrast swallow. Cricopharyngeal myotomy was performed in all patients. One child died in the postoperative period because of respiratory failure secondary to aspiration pneumonitis, whereas in the other two, symptoms were relieved, and they remain asymptomatic on follow-up.

The A to Z of Peroral Endoscopic Myotomy.
J Clin Gastroenterol

Peroral endoscopic myotomy (POEM) is a novel technique within the field of third space endoscopy. The overarching principal is creation of a mucosal incision, careful dissection of the submucosal space using an electrosurgical knife to reach the muscularis (ie, tunneling), performing a controlled myotomy, and finally, closure of the mucosal incision. POEM was first developed for the management of achalasia, and now a decade of evidence shows the procedure is safe, effective, and highly reproducible.

To establish a novel laryngopharyngeal reflux model in Bama minipigs excluding concurrent gastroesophageal reflux through endoscopic cricopharyngeal myotomy. Twelve 8-month-old male Bama minipigs were randomly assigned to three groups: Group 1 underwent cricopharyngeal myotomy alone, Group 2 underwent combined cricopharyngeal and lower esophageal sphincter myotomy, and Group 3 served as the control group. Following a one-week acclimatization period, the respective surgical procedures were performed.

Article Synopsis
- The study focused on patients with Zenker's diverticulum who were treated using cricopharyngeal myotomy with flexible endoscopic septal division.
- A total of 15 patients underwent this procedure, with a reported clinical success rate of 80%, although 20% experienced a return of symptoms.
- The findings suggest that despite new techniques in endoscopy, traditional cricopharyngeal myotomy is still an effective treatment for this condition.

Objective: Zenker diverticulum is a mucosal herniation at the pharyngoesophageal junction. Although open surgical myotomy is the conventional treatment, robust evidence on third-space flexible endoscopic myotomy is lacking. We assessed safety, effectiveness, and patient-reported outcomes of per-oral endoscopic myotomy (Z-POEM) in the largest reported single-center experience with this technique.
