Abstract Background and study aims A 70-year-old-man underwent an esophagectomy and posterior mediastinal reconstruction for esophageal cancer that was curatively resected. Although the patient was allowed to eat after surgery, he repeatedly vomited after drinking water or eating meals and required continuous hospitalization. An upper gastrointestinal series and endoscopic examination revealed an obstruction due to the flexure of the gastric conduit, which was repeatedly treated with endoscopic balloon dilation. Endoscopic balloon dilation was completely ineffective, however, because the obstruction was not due to a small lumen diameter, but rather to severe flexure. We hypothesized that the power of contraction provided by ulcer scar formation after mucosal resection could straighten the flexure, and thus removed a piece of the mucosa 8 cm in diameter on the oral side of the flexure by endoscopic submucosal dissection (ESD) 4 months after the esophagectomy. Endoscopic examination on post-ESD Day 10 revealed that the gastric conduit flexure was straightened due to ulcer scarring, and obstruction at the flexure opened over time. Meals were restarted and the patient could eat without vomiting. He was discharged from the hospital 5 weeks after ESD. This is the first case report of obstruction due to flexure of the gastric conduit after esophagectomy that was successfully treated with mucosectomy using ESD. Mucosectomy using ESD may be an effective treatment option for obstruction due to flexure of the gastric conduit after esophagectomy.

ABSTRACT We investigated the efficacy and safety of radial incision and cutting as a novel dilation method for strictures just before endoscopic submucosal dissection in patients with metachronous esophageal cancer localized on the distal side of strictures and determined the optimal dilation method. Consecutive patients who underwent endoscopic submucosal dissection for superficial esophageal squamous cell carcinomas localized on the distal side of severe strictures were investigated retrospectively and assigned to a radial incision and cutting (19 patients; 23 lesions) or an endoscopic balloon dilation (20 patients; 20 lesions) group. We evaluated the passage success rates of cap-wearing endoscopes with diameters ≥8.9 mm, the procedural success, en bloc resection, complete resection, major adverse event rates, and total procedure times. Compared to the endoscopic balloon dilation group, the passage success rate of a conventional endoscope with a transparent cap (87% vs. 50%) and procedural success rate (96% vs. 63%) were significantly higher in the radial incision and cutting group. The mean procedure time of ‘dilation and ESD’ was significantly shorter in the radial incision and cutting group than in the endoscopic balloon dilation group. Neither group experienced any serious adverse events. Radial incision and cutting followed by endoscopic submucosal dissection was effective and safe in patients with superficial esophageal squamous cell carcinomas localized on the distal side of severe benign esophageal strictures. Endoscopic submucosal dissection using a cap-wearing endoscope was possible with radial incision and cutting, and the procedure time was shorter than that for endoscopic balloon dilation.
