Treatment of a completely obstructed colonic anastomotic stricture by using a prototype forward-array echoendoscope and facilitated by SpyGlass (with videos)

BackgroundColonic anastomotic strictures complicate colorectal resection in up to 7% of cases and are often managed with endoscopic dilation. Complete anastomotic obstructions are rare and have traditionally required surgical remediation.ObjectiveTo demonstrate a novel endoscopic approach to treat complete colonic anastomotic obstruction.DesignCase report.SettingTertiary-referral center.PatientA 40-year-old woman with a completely obstructed colonic anastomosis after sigmoidectomy for a fibrotic Crohn's stricture.InterventionsA prototype front-view and forward-array echoendoscope was used to recanalize the completely obstructed anastomotic stricture. Real-time EUS imaging guided puncture through the stenosis. Access into the proximal obstructed segment was confirmed by using SpyGlass fiberoptic probe visualization. Subsequent stricture dilation was performed by using wire-guided balloon dilators through the instrument channel of the prototype echoendoscope, and luminal continuity was reestablished.Main Outcome MeasurementsTechnique success and complications.ResultsThe completely obstructed anastomotic stricture was successfully recanalized and dilated by using a single, prototype, forward-array echoendoscope without complications.LimitationsSingle case report with a relatively short follow-up interval.ConclusionsEUS-guided puncture and dilation of completely obstructed anastomotic strictures is feasible when using a prototype forward-array echoendoscope. This novel technique appears to be an effective method to reestablish luminal continuity across completely obstructed strictures.
