Outcomes in modified transoral resection of diverticula for Zenker’s diverticulum

Endoscopic management of Zenker’s diverticulum: stapling vs. Z-POEM

“…Similar results are described by the most of authors (8)(9)(10)(11)(12)(13)15,25). The only two prospective studies present in literature showed good clinical results in 77.68% and 76% respectively (6,7).…”

“…Two studies out of 20 were prospective (6,7), 11 were retrospective (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18), 6 case reports (19)(20)(21)(22)(23)(24) and 1 clinical review (25).…”

“…Of the retrospective studies, 6 were comparative studies between ESD and other treatment techniques, such as the flexible endoscopic treatment (9), CO 2 laser (11)(12)(13), open surgery (12,14,15) or a new technique called MTORD (transoral resection of diverticulum) (15). About Z-POEM we reviewed 6 case reports, 1 retrospective study and 2 comparative retrospective studies where the Z-POEM's outcomes were compared to the classic endoscopic septotomy (17,18).…”

Transoral Laser-Assisted Diverticulectomy: Swallow Study Results after Complete Endoscopic Pouch Excision for Zenker’s Diverticulum

“…Traditionally, the open transcervical approach to a Zenker's diverticulum has the advantage of complete diverticulum excision (diverticulectomy) in comparison to historic transoral techniques that focus on the division of the cricopharyngeus muscle and common wall between the cervical esophagus and the diverticulum (diverticulotomy). 12,13 Transcervical approaches have been shown to have longer operative time, hospital stay, and external scar, however this approach has reduced recurrent dysphagia and revision rates in comparison to transoral endoscopic approaches. 13,14 Endoscopic excision of the diverticula after cricopharyngeal myotomy, as previously described by Mortenson and Junlapan, 8,13 combine the advantages of endoscopic approaches while attempting to decrease the residual pouch size.…”

Both techniques combine endoscopic cricopharyngeal myotomy followed by medial retraction of the pouch and excision using either cold instrumentation (Mortenson) or CO2 laser (Junlapan).…”
