What is a contraindication for endoscopic foreign body removal?

The identification of sharp or irregular objects as a contraindication for endoscopic foreign body removal is based on the increased risk of injury to the gastrointestinal tract. When the foreign body has sharp edges or an irregular shape, there is a higher likelihood that it can cause lacerations or perforations during retrieval. This can lead to serious complications such as bleeding, infection, or abdominal perforation, which could necessitate surgical intervention. Therefore, careful consideration is essential when assessing the risks associated with attempting endoscopic removal of such objects.

Other options, while they may present particular challenges or considerations during an endoscopic procedure, do not directly serve as absolute contraindications. For instance, foreign bodies in the esophagus are typically an indication for endoscopic removal, and patients with a history of allergies, unless specific to the materials in use during the procedure, are generally not excluded from undergoing this intervention. The presence of small bowel obstruction requires a different management approach, but it does not categorically contraindicate endoscopic retrieval of a foreign body, especially if it is located proximally and can be safely addressed.
