Abstract
Background and aim: Complete gastrointestinal strictures are a technically demanding problem. In this setting, an anterograde technique is associated with a high risk of complications and a combined anterograde-retrograde technique requires a prior ostomy. Our aim was to assess the outcome of a first case series for the management of complete gastrointestinal strictures using endoscopic ultrasound (EUS)-guided puncture as a novel endoscopic approach. Patients and methods: This retrospective case-series describes four cases that were referred for treatment of complete benign gastrointestinal strictures, three upper and one lower. Recanalization was attempted with EUS-guided puncture using a 22G or 19G needle and contrast filling was visualized by fluoroscopy. Afterwards, a cystotome and/or a dilator balloon were used under endoscopic and fluoroscopic guidance. A fully covered metal stent was placed in two cases, keeping the strictures open in order to prevent another stricture. Feasibility, adverse events, efficacy and the number of dilations required after recanalization were evaluated. Results: Technical and clinical success was achieved in three of the four cases (75%). A first dilation was performed using a dilator balloon in all successful cases and fully covered metal stents were used in two cases. These patients underwent a consecutive number of balloon dilatations (range 1-4) and all three were able to eat a soft diet. No adverse events were related to the EUS-guided approach. In the failed case with a long stricture (> 3 cm), an endoscopic rendezvous technique was attempted which caused a pneumothorax requiring a chest tube placement. Conclusion: EUS-guided recanalization, as a first approach in the treatment of complete digestive stricture, is a feasible and promising procedure that can help to avoid major surgery.
