“…Its flexibility makes the system difficult to pass through the stenosis. There is a report [ 21 ] that revealed the usefulness of stent placement using an overtube for malignant gastroduodenal obstructions. Our idea involves the same method of preventing flexure in the greater curvature as in that study.…”

This is a retrospective study to evaluate the prevention of complications of metallic stent placement in patients with unresectable advanced esophageal cancer. A total of 87 patients were treated with 4 types of metal stents in the esophagus over a period of 18 years. Stent placement was technically successful. The most common prior treatment was chemoradiotherapy. There were no significant differences in the rate of patients with no complications among the prior treatments. Approximately, 30% of patients had the most common chest pain in complications. Stent placement within one month after the completion of chemoradiotherapy should be avoided for the prevention of the chest pain. There was no significant difference in the rate of patients with no complications by lesion location. The rate of no complications was higher for the Niti-S stent than the Gianturco Z-stent or Ultraflex stent. Of note, no complications were noted for the Niti-S ultrathin stent at all. Among cases of stent-related death, the most common type of complication was respiratory disorder caused by the stent that seems to be thick and hard. Therefore, the stent with thin and flexible characteristics like the Niti-S ultrathin stent will solve the various problems of esophageal stent placement.

“…If the proximal end of the tailored stent did not completely fit into the residual antral wall, the recycling thread of the stent was pulled up by endoscopy, or an ERCP balloon catheter was used to push the stent forward in order to adjust the location of the stent. The whole procedure was performed under fluoroscopic guidance ( Figure 2(a) ) [ 19 , 20 ]. The standard uncovered stents were implanted by a through-the-scope method [ 6 , 21 ].…”

The aim of our study is to compare the efficacy and safety of “outlet-shape” tailored stents with standard stents for the management of distal gastric cancer causing gastric outlet obstructions (GOOs) with varying gastric cavity shapes and sizes. To determine the shape and size of the GOOs, stomach opacifications were performed using contrast media before stenting. Two basic shapes of the residual cavity of the proximal GOO were observed: cup shaped or approximately cup shaped and funnel shaped or approximately funnel shaped. Other shapes were not found. In the GOO tailored group, the size and shape of the proximal ends of the tailored stent were suited for the residual cavity of the proximal GOO. The tailored stents included large cup-shaped stents and large funnel-shaped stents. GOO tailored covered stents led to less restenosis and reintervention rates compared to standard uncovered stents but with the same survival.

Peroral placement of a self-expandable covered metallic stent using an overtube for malignant gastroduodenal obstructions

Abstract: The placement of a large diameter, self-expandable, covered esophageal stent using an overtube appears to be effective for the palliative treatment of malignant gastric outlet obstruction.
