A 34 year-old woman was referred to us for persistent dysphagia and retrosternal chest pain, aggravated by eating. Two years earlier, she underwent a laparoscopic sleeve gastrectomy for morbid obesity. Her operation was complicated by septic shock due to an esophagogastric fistula with subphrenic abscesses, and on postoperative day 20, she underwent a laparotomy, abscess debridement and drainage, splenectomy and application of cyanoacrylate-based glue, followed by endoscopic positioning of a self-expandable partially coated prosthesis. Three weeks afterwards, her prosthesis was replaced with a self-expandable fully coated prosthesis due to persistent leak. This prosthesis was finally removed after 7 weeks. One year after her operation, at gastroscopy, a 25mm submucosal nodule covered with an ulcerated mucosa was found in the proximal antrum. Biopsy was negative, and endoscopic ultrasonography was suggestive of GIST. She underwent an esophageal manometry, which was indicative of esophagogastric junction outflow obstruction. Her barium swallow test showed a delayed esophageal emptying due to the narrowing and twisting of the proximal part of the stomach. Her abdominal MRI was normal. An exploratory laparoscopy was indicated for adhesiolysis and removal of the antral lesion. Total duration of the operation was 3 hours. Her postoperative course was uneventful and she was discharged on postoperative day 6. Her postoperative swallow study showed the easy passage of the contrast agent with no leaks. The patient completely recovered from her symptoms, and remained asymptomatic after 30 months. Final histology of her lesion evidenced a foreign body granuloma.
