BACKGROUNDLeakage from esophageal and gastric perforation carries a high morbidity and often requires surgical intervention. In spite of the promising early results from esophageal stenting, migration of the stent continues to plague the physician, and occurs twenty to sixty percent of the time. A new technique to prevent migration of the stent is described.
METHODSTen patients presenting with leakage from the foregut underwent stent fixation with a novel technique in a single institution from January 2008 to January 2011.
RESULTSFive patients who previously presented with stent migration and required re-positioning of the stent successfully had stent fixation with the temporary bridle technique. An additional five patients who were at high risk for stent migration had the new technique used and experienced successful anchor of the stent.
CONCLUSIONSThis novel technique of stent anchoring to prevent migration is both safe and effective when treating patients with benign leaks and fistulas of the foregut. Until non-migrating stents can be developed, such techniques will be required to prevent additional complications.
migrated Polyflex into the stomach
migrated Wallflex into distal jejunum
bridled & re-positionedWallflex w contrast
bridled Wallflex
TECHNIQUE:
Endoscopic stent placement
Endoscopic rat tooth forcep delivery of umbilical tape into center of stent & released
Pass rat tooth through proximal uncovered metal Weave of the stent and grasp umbilical tapeDeliver other end of umbilical tape out of mouth
Re-position both ends of tape through nares with ET suction Catheter and tie to prevent distal migration
Polyflex is removed and new Wallflex is placed
Bridle holding stent
Bridle is removed after 4 dayswhich is enough time for tissueingrowth to occur and preventmigration…
Non-FDA-approved removal is performed within 30 days if for leak
