However, rigid oesophagoscopy
is necessary when there are severe problems in cases of sharp and penetrative objects.
, eleven patients (78.57%) had their foreign body extracted, whereas, spontaneous propulsion happened in three patients only (21.43%).
This retrospective study was conducted at the Aga Khan University Hospital (AKUH), Karachi, and comprised medical charts of patients who had undergone oesophagoscopy
for removal of foreign body (fish and chicken bone) from 1990 to 2015.
One patient developed abscess 4 days after Oesophagoscopy
was performed for foreign body removal.
Under anaesthetic, oesophagoscopy
revealed the origin of the protruding tissue mass to be at the cricopharyngeus, establishing the diagnosis of a prolapsed Zenker's diverticulum that was repaired via a left lateral cervical incision.
Tumour length can be assessed with oesophagoscopy
(Figure 4), barium swallow study, computed tomography, endoscopic ultrasonography and histopathological examination of resected specimen.
Some went on--unnecessarily--to computed tomography (CT) scans, upper oesophagoscopy
(in a colleague complaining of dysphagia), lung function testing, bronchoscopy, tissue biopsy (of pleura, lymph node and lung), magnetic resonance imaging scans and CT angiograms, and ran into complications following invasive tests.
Direct laryngoscopy, bronchoscopy and oesophagoscopy
were performed before operating if injuries to the respiratory or food passages were suspected.
Other investigations or diagnostic procedures undertaken in the private sector included upper oesophagoscopy
(in a participant complaining of dysphagia), lung function testing, bronchoscopy, tissue biopsy (of pleura, lymph node and lung), magnetic resonance imaging (MRI) scans and CAT angiograms.
