BACKGROUND: Covered metallic or plastic stent placement has become an important treatment for postoperative esophageal leakage; however, fluoroscopic guidance is also required. Here we present a novel stent insertion technique with a newly designed proximal-releasing, self-expanding metallic stent (PR-SEMS) and transnasal endoscope that can enable stent insertion without fluoroscopy as a new method to prevent stent migration.

OBJECTIVE: To describe our experience with 7 patients who underwent PR-SEMS insertion with the direct-vision technique and our use of the transnasal endoscope without fluoroscopy.

DESIGN: Prospective outcome study.

SETTING: A tertiary-care referral university hospital.

PATIENTS: This study involved all patients at our center who experienced postoperative esophageal leakage after esophagectomy, primary closure, or total gastrectomy.

INTERVENTION: PR-SEMS insertion with the direct vision technique and use of transnasal endoscopy without fluoroscopy.

MAIN OUTCOME MEASUREMENTS: Success rate of stent insertion, healing rate of postoperative esophageal leaks, and stent migration rate.

RESULTS: All stents were placed at the expected location without complications. One patient had massive hematemesis and underwent surgery. The bleeding focus was the splenic artery, which was damaged during gastrectomy. A significant marginal ulcer occurred in one patient, and the stent was immediately retrieved with an endoscope. After stent removal, 4 postoperative leakages were completely healed, and 2 lesions were not occluded. The 2 remaining minimal lesions became completely occluded with conservative management after stent removal. Stent migration did not occur.

LIMITATIONS: A small number of patients. Further prospective, randomized, controlled trials are needed.

CONCLUSION: PR-SEMS insertion under transnasal endoscopic guidance is a feasible, safe, and effective treatment for postoperative esophageal leakage, and it can be performed as a bedside procedure. Our anchoring method is effective for the prevention of migration from nonobstructed lesions.
