Early diagnosis and management of delayed bleeding in the submucosal tunnel after peroral endoscopic myotomy for achalasia (with video)

Accuracy of a scoring system for the differential diagnosis of common gastric subepithelial tumors based on endoscopic ultrasonography

“…Endoscopic resection is preferred over surgical resection in the differential diagnosis and treatment for gastric SET because it is less invasive. Several studies [24][25][26][27][28][29] have reported that endoscopic treatment is an effective, feasible and safe method to remove gastric SET.…”

Per-oral endoscopic myotomy white paper summary

“…These bleeding episodes were managed conservatively with hospital observation and/or transfusions and, occasionally, in Asian centers, with endoscopic re-exploration of the tunnel and endoscopic hemostasis or tamponade with Blakemore-type balloons. 18,52 Other very rare and unusual adverse events have been anecdotally presented and may be center dependent and of little general significance, for example, acute mucosal sloughing, food impaction, and intractable nausea. Late adverse events.…”

Optical coherence tomography (OCT) prior to peroral endoscopic myotomy (POEM) reduces procedural time and bleeding: a multicenter international collaborative study

“…Although POEM is generally well tolerated with minimal complications as described by Inoue's initial set of 17 patients [4], there are some reports of bleeding. Li et al [12] published a report of delayed bleeding in 3/428 POEM patients (0.7 %), all of which were conservatively managed. Delayed bleeding is thought to occur at the cut muscular edges due to abundance of blood vessels and collateral circulation at the layers of the esophagus [13].…”
