“…However one can argue that this method with magnets is also used to perform nonsurgical gut anastomoses [11,12] and there is the risk of inducing ischemia and necrosis in the gullet wall. Apart from the fact that mucosal tissue enclosed between the two magnets does not contain vessels, it is necessary to specify that the attractive force between our magnets was 0.16 N/cm 2 of material, a value markedly lower than that previously used for performing gut anastomoses [11], which was 0.52 N/cm 2 of material.…”

The present research demonstrates that it is possible to create at the LES level a dynamic closure of a value considered sufficient to prevent GER, by implanting in the esophageal submucosa of anatomical specimens a magnetic device by means of a special endoluminal probe. Once effectiveness and tolerability of magnets covered by a biocompatible sheath have been demonstrated in vivo, this device could become a simple and effective nonsurgical solution to GER.

“…In 1991, Swain and Mills reported on gastrojejunostomy performed using flexible forward-view endoscopy using a special compression button [13]. Since then, several investigators reported on gastrojejunostomy using flexible forward-view endoscopy in mainly animal studies and a few clinical studies using flared-type metal stents, magnets or natural orifice transluminal endoscopic surgery [14][15][16][17][18][19][20]. In 2002, Fritscher-Ravens et al reported on EUS-guided gastrojejunostomy in pigs using a special compression button [21,22].…”

Surgical intervention and, more recently, endoscopic intervention have been performed for the treatment of malignant gastric outlet obstruction. Recently, endoscopic ultrasonography (EUS)-guided gastrojejunostomy using special devices has been established. In line with this, we have developed a novel EUS-guided double-balloonoccluded gastrojejunostomy (EBOG) using a lumenapposing biflanged metal stent. Herein, we describe the technique and outcome of EBOG.

“…Im Anschluss kann in einem zweiten Schritt eine weiterreichende bariatrische Operation zur Ergänzung der Malabsorption bei nicht ausreichendem Gewichtsverlust angeschlossen werden. In ersten tierexperimentellen Untersuchungen wurden neue endoskopische Methoden zur Erstellung von gastrointestinalen Anastomosen beschrieben [21,22]. In einer aktuellen Arbeit wird eine Methode beschrieben, bei der durch den Einsatz von Magneten und einem speziellen Stentsystem bei Patienten mit Magenausgangsstenose eine gastrointestinale Anastomose endoskopisch erzeugt wurde [23].…”
