Worldwide, peroral endoscopic myotomy (POEM) has achieved remarkable initial outcomes in the treatment of achalasia. In China, POEM has developed very quickly since the first case was performed in our center in August 2010. With ex-perience, we have successfully performed POEM for special cases (such as pediatric patients, patients with sigmoid-type esophagus, and patients with recurrent sympto...

Recent scholarship has developed an increasing interest in the materiality of ancient manuscripts. Opisthographs, manuscripts that contain writing on both sides, are special this regard. This short study focuses two papyrus opisthographs, originating from different collections: Oxyrhynchus Papyri and Dead Sea Scrolls. These each bear compositions front side (the recto) back verso). The Greek Pa...

Despite its apparent popularity in fifteenth-century Ireland—as attested by its presence in eight manuscripts—Stair Fortibrais, the Irish adaptation of the twelfth-century chanson de geste Fierabras has received very little scholarly attention. This fact proves especially unfortunate since the text possesses particular relevance for two important trends in recent scholarship, one concerning Cel...

Arabic manuscripts (almost a third of McGill's Arabic holdings) comprising copies of 62 different works. The manuscripts collected by Osler were acquired mainly from a professional colleague in Hamadhan in western Iran; others were obtained later and originated in the collections of two well-known Islamists: the Russian scholar V. Ivanow, and the German physician and Arab medical historian Max ...

BACKGROUND/AIM Several uncontrolled studies comparing peroral endoscopic myotomy (POEM) and Heller myotomy have demonstrated equivalent short-term efficacy and safety. However, no data exists rergarding the cost of POEM and how it compares to that of robotic Heller myotomy (RHM). The primary aim of this study was to compare the inpatient charges incurred in patients who underwent POEM or RHM fo...

BACKGROUND AND STUDY AIMS With the success of peroral endoscopic myotomy (POEM) in treatment of achalasia, its successful application to other spastic esophageal motility disorders such as Jackhammer esophagus has been noted. The question of whether the lower esophageal sphincter (LES) should be included in the myotomy for Jackhammer esophagus is a topic of current debate. Here, we report our e...

Background and study aims Per-oral endoscopic myotomy (POEM) has emerged as an efficacious treatment modality for the management of achalasia cardia (AC) and non-achalasia spastic esophageal motility disorders. Initial results are encouraging. We analyzed the safety and efficacy of POEM in a large cohort of patients with AC. Patients and methods The data from patients who underwent POEM (from J...

Peroral endoscopic myotomy (POEM) has been established as an optional treatment for achalasia. POEM is an endoluminal procedure that involves dissection of esophageal muscle fibers followed by submucosal tunneling. Inoue first attempted to use POEM for the treatment of achalasia in humans. Expanded indications of POEM include classic indications such as type I, type II, type III achalasia, fail...
