Rendezvous endoscopy using a transillumination fashion as a feasible and safe alternative to endoscopic ultrasound‐guided recanalization in case of complete anastomotic stricture

Self-expandable metal stent (SEMS) are widely utilized as a bridge to surgical intervention and for palliative treatment of malignant bowel obstructions. The risk of complications associated with SEMS is low in well-selected patients. Stent erosion is a rare but serious adverse event that is associated with high morbidity and mortality. Here, we report the case of a 74-year-old patient with a colonic obstruction secondary to a pelvic mass that was treated with SEMS and radiotherapy, who developed a partial thickness stent erosion and recurrent hematochezia 6 years after placement. Endoscopic retrieval was not technically feasible. During attempted surgical resection, massive hemorrhage occurred from a colonic-arterial fistula to the left external iliac artery resulting in death. While SEMS remain an effective, minimally invasive approach for the management of bowel obstructions, prolonged in-situ lifetime may confer an increased risk of serious adverse events including erosion and fistula formation.
