This fit and well woman in her 40s presented to A+E with a foreign body throat sensation and dysphagia after swallowing her analgesic tablets in the middle of the night. She was reviewed by the ear, nose and throat team and at that stage she was tolerating fluids, had no airway difficulties and could mobilise her neck. Chest and lateral neck X-rays were normal and flexible nasendoscopy revealed no abnormalities of the larynx. A hypopharyngeal/oesophageal abrasion sustained as she swallowed the tablets was the presumed diagnosis and she was discharged with advice to return in 48 hours if no improvement. She was admitted 3 days later with ongoing symptoms and treated with steroids and analgesics for 48 hours until she clinically improved for discharge. An outpatient barium swallow was requested and performed 5 days later. She remained as inpatient for 48 hours after the swallow test for symptom control and for the test results. It was reported as a normal study with ‘Buildup of contrast in the oesophagus adjacent to T1 and T2 which likely represents barium accumulating between mucosal folds’ (figure 1). She was again discharged but given the persistent symptoms she was referred for outpatient oesophagogastroduodenoscopy (OGD). Five days later, an OGD revealed she had swallowed her tramadol tablets whole in the original foil packet which was lodged in the upper oesophagus (figure 2). She underwent rigid oesophagoscopy and removal of foreign body uneventfully (17 days after ingestion of her tablets!) and she was discharged after a period of observation.
Foreign body in the oesophagus carries a significant risk of morbidity and mortality; due to oesophageal perforation, fistulisation, mediastinitis/sepsis and airway obstruction.1 A detailed history of what has been ingested and when is required to help grade the urgency of investigation and removal, as some objects may be sharp or corrosive, and so on, so carry higher risk of perforation and its sequelae. This case teaches us not to rely on barium swallow to rule out foreign body oesophagus; and the need for more sensitive investigations like CT scan or oesophagoscopy. A study published in peer-reviewed Acta Radiologica found the sensitivity of barium swallows to be 87.5% for detection of upper oesophageal foreign bodies, with fish bone being the main foreign body not detected.2 A larger study published in the Annals of Otology, Rhinology & Laryngology found that CT scan has 100% sensitivity for ingested foreign body, and they are also more useful at diagnosing complications such as perforation.3 CT scan may also be a safer option than OGD, particularly pertinent in elderly patients with multiple comorbidities. Where clinical suspicion of foreign body oesophagus is high oesophagoscopy or CT scan would be preferred ahead of barium swallow, however, in this case a foreign body was thought to be highly unlikely as the patient could relay a full history and the foreign body in question should have been a dissolvable tablet. In retrospect viewing of the barium swallow we can see the tramadol packet, however everyone was surprised when it was discovered at OGD!
I had no idea I swallowed this! It was a very frightening 3 weeks and I couldn’t believe when I saw the picture! Thank you for all your help.
Higher sensitivity of CT scan and oesophagoscopy compared with barium swallow for suspected oesophageal food bolus.
Early oesophagoscopy and removal of impacted food bolus/foreign body to avoid oesophageal perforation and sequelae.
Caution with patients who cannot provide reliable history as to what was ingested and when.
