“…The clinical outcomes of POEM have been reported in a recent large multi-centre study: the initial 96% success rate at 6 months decreased to 91% at 2 years of follow-up, a similar success rate of the present study (18). Another large multicenter study from Europe reported an initial success rate of 97% at 3 months that decreased to 87% at 1-year follow-up (19).…”

Peroral endoscopic myotomy using FlushKnife BT: a single-center series

et al. 2017

Background and study aims Peroral endoscopic myotomy (POEM) is an evolving new treatment strategy for achalasia. Although several kinds of electrosurgical knives have been used in performing POEM, the best device has yet to be determined. The FlushKnife BT is a waterjet-emitting short needle-knife with a small ball tip (BT) that offers the potential to perform all aspects of POEM with a single device. In this study, we evaluated the safety and efficiency of the FlushKnife BT for POEM. Patients and methods A total of 54 consecutive patients with achalasia and other spastic esophageal motility disorders, such as jackhammer esophagus or distal esophageal spasm, who underwent POEM between January 2016 and August 2016, were included in this retrospective study. Results The median operation time was 73.0 minutes (range 39 – 184 minutes). All procedures were completed using only the FlushKnife BT without changing to any other electrosurgical instrument. The median number of additional submucosal injections with an injection needle was 0 (range 0 – 1). Endoscopic vessel sealing was performed a mean of 3 times (range 0 – 7). The median number of bleeding episodes requiring treatment with hemostatic forceps was 0 (range 0 – 5). There were no significant adverse events. Seven of 52 patients (13.5 %) reported symptoms of gastroesophageal reflux disease such as heartburn or acid reflux at 3 month follow-up. Conclusions The FlushKnife BT enabled POEM to be performed with very few device exchanges, either for re-injection or to control intraoperative bleeding. In this uncontrolled case series, the ability of the FlushKnife BT to perform nearly all aspects of the POEM procedure seems to make it particularly well suited to this procedure.

“…International consensus guidelines are currently being developed for the management of achalasia and should provide an evidence basis to inform such discussions. Further new interventions in the management of achalasia not examined in this study include peroral endoscopic myotomy (POEM), a promising new method for performing endoluminal myotomy. POEM is a technically demanding procedure and requires a high level of endoscopic skill with careful patient selection, again suggesting the need for multidisciplinary team discussion of patients with oesophageal achalasia.…”
