Endoscopic transluminal drainage and necrosectomy by using a novel, through-the-scope, fully covered, large-bore esophageal metal stent: preliminary experience in 10 patients (original) (raw)

Gastrointestinal endoscopy

Interventions for necrotizing pancreatitis have undergone a recent paradigm shift toward minimally invasive techniques, including endoscopic transluminal necrosectomy (ETN). The optimal stent for endoscopic transmural drainage remains unsettled. To evaluate a novel large-bore, fully covered metal through-the-scope (TTS) esophageal stent for cystenterostomy in large walled-off necrosis (WON). Retrospective case series. Single tertiary care academic center. Ten patients with large (>10 cm) WON collections who underwent endoscopic transmural drainage and ETN. Initial cystenterostomy was performed by using EUS, and in the same session, a TTS (18 × 60 mm), fully covered esophageal stent was placed to create a wide-bore fistula into the cavity. In 1 or more later sessions, the stent was removed, and ETN was performed as needed. Technical and clinical success rates and adverse events. The TTS stent was successfully deployed at the initial cystogastrostomy in all 10 patients. All patient...
