Summary

To compare the efficacy of a novel partially covered (PC) versus uncovered (UC) pyloro-duodenal stents (DS) in unresectable malignant gastric outlet obstruction. We hypothesize that the use of PCDS could reduce the re-intervention rates when compared to UCDS.

Conditions

  • Unresectable Malignant Gastric Outlet Obstruction

Interventions

OTHER

Partially covered pyloro-duodenal stent

The PCDS (Niti-S COMVITM - Flare, Taewoong, Gyeonggi-do, South Korea) used in the current study is a partially covered metallic pyloro-duodenal stent. It consists of two portions (Figure 1). The stent is 2cm in diameter and the proximal 2cm of the stent is uncovered and flared. This is designed to provide anchorage of the stent to surrounding tissue and reduce the risk of migration. The remaining of the stent is covered, where a polytetrafluoroethylene (PTFE) membrane is held between two nitinol mesh to prevent the risk of tumour ingrowth into the stent. The stents come in lengths of 6, 8, 10 \& 12cm.

OTHER

Uncovered pyloro-duodenal stents

The UCDS (Niti-S pyloric-duodenal D stent, Taewoong, Gyeonggi-do, South Korea) used in the current study is an uncovered stent made of nitinol wire, with a diameter of 20mm and length of 6,8,10,12cm. This stent is an unfixed-cell braided stent with low axial force, high flexibility and good conformability.
