# ============ 1. INTRODUCTION ============
h1("1. INTRODUCTION")
p("Foreign body (FB) impaction in the oesophagus is a common otolaryngological and gastrointestinal emergency "
  "encountered across all age groups, but especially in young children and in elderly, edentulous, or "
  "psychiatrically ill adults. The oesophagus, being a muscular conduit with three natural anatomical "
  "narrowings, is the most frequent site at which swallowed objects become arrested. Objects range from "
  "coins and button batteries in toddlers to food boluses, fish bones, and chicken/meat bones in older "
  "children and adults. Although many foreign bodies pass spontaneously once they reach the stomach, those "
  "that lodge within the oesophagus, particularly sharp or bony objects such as chicken bone, pose a genuine "
  "risk of mucosal injury, perforation, mediastinitis, and life-threatening vascular fistulation if not removed "
  "promptly. Early recognition, appropriate imaging, and timely endoscopic retrieval are the cornerstones of "
  "safe management, and skilled nursing care is essential in the pre-procedural stabilisation, peri-operative "
  "monitoring, and post-procedural recovery of the patient. This presentation uses the real hospital record of "
  "a 12-year-old female admitted to the ENT ward with a chicken-bone foreign body in the oesophagus as the "
  "clinical anchor for a comprehensive review of the condition and of the nursing role in its management.")

p("The patient was apparently well until one day prior to admission, when, while eating chicken curry at "
  "home, she suddenly felt something get lodged in her throat while swallowing a piece of meat. This was "
  "immediately followed by a bout of coughing/gagging, throat pain, and an inability to comfortably continue "
  "eating. The family tried home remedies including swallowing extra rice and water in an attempt to push the "
  "object down, without relief. Over the next 24 hours she continued to have a persistent foreign-body "
  "sensation localised to the lower throat/retrosternal area, worsening odynophagia, and mild drooling of "
  "saliva. There was no noisy or laboured breathing, no cyanosis, no haematemesis, no fever, and no vomiting. "
