A 65-year-oldman presented to the emergency department with a foreign body in his rectum. He had inserted a Cuban cigar case into his anus approximately 9 hours before admission. The case had no sharp edges, and its cap was on. The patient’s abdomen was soft and not distended. Abdominal radiography showed a long, radiopaque, cylindrical foreign body in the rectum and sigmoid (●" Fig.1), with no signs of perforation. Proctosigmoidoscopy, performed without sedation, confirmed the presence of the object (●" Fig.2). Several attempts were made to remove it with a polypectomy snare, but the foreign body was very long and inflexible, so that it could not pass through the acute angle of the rectosigmoid junction. An esophageal overtube was then introduced up to the proximal edge of the cylindrical case, reducing the angle of the rectosigmoid junction so that the distal tip of the case could be disimpacted (●" Video 1). With its distal tip fixed by a polypectomy snare, the foreign body was moved to the distal rectum and finally removed with manual assistance (●" Fig.3). Afterward, the endoscope was removed, and no complication followed the procedure. The patient was asymptomatic at discharge. Retained rectal foreign bodies are not uncommon and often present a management dilemma [1,2]. Frequently, hospital admission is delayed until after several efforts have been made to remove the object at home [1]. Extraction can be difficult, and severe complications may occur [1]. Low-lying foreign bodies are usually palpable on digital rectal examination and can often be removed manually [3]. High-lying foreign bodies are located proximally to the rectosigmoid junction, and proctosigmoidoscopy is required for removal [3,4]. Surgery should be reserved for unstable patients, those with perforation, and those in whom transanal attempts at removal have failed [1]. To the best of our knowledge, no previous cases in which this technique was used have been described. The use of an overtube can straighten the colorectum, facilitating the removal of a rectal foreign body.
