Esophagus and GERD Flashcards
Odynophagia
pain on swallowing
Dysphagia
symptom resulting from failure to move food from mouth to stomach
Normal Swallowing
Transfer –> liquids/solids move from mouth to esophagus
Transport –> liquids/solids move length of esophagus
Emptying –> liquids/solids delivered to stomach
Contributing factors to dysphagia?
- Inadequate preparation of swallowing –> saliva/mastication, neuromuscular disorder
- Abnormal muscle strength/function –> neuromuscular disorder
- Esophageal passageway narrowing –> mechanical obstruction
Oropharyngeal dysphagia
difficulty initiating swallowing Goals of therapy - protect airway - maintain nutrition - relieve dysphagia Therapies - speech/swallowing therapy - esophageal dilation - surgical myotomy - NPO with nutrition support
Esophageal dysphagia
food stops/sticks after swallowing initiated
Anatomic causes of dysphagia
Benign –> peptic strictures, rings/webs, caustic
Cancer –> primary esophageal, extrinsic compression
Neuromuscular causes of dysphagia
Primary esophageal disease
- Achalasia
- Chagas’
Achalasia
loss of inhibitory innervation to LES
- non-relaxing LES, esophageal aperistalsis
- bird’s-beak narrowing, dilated esophagus
Treatment of achalasia
- Nifidepine
- Botulinum toxin
- Balloon dilation
- Esophageal myotomy
Heartburn
Classic symptom of GERD
- substernal burning w/ or w/o regurgitation
- post-prandial
- aggravated by change in position
- prompt relief with antacids
Therapy of GERD
LIFESTYLE MODIFICATIONS
- elevate head
- no food 3 hrs before bed
- modify diet –> decrease fat, volume, and acid
Barrett’s Esophagus
columnar epithelium replaces squamous epithelium in distal esophagus (distal 1/3)
- occurs as a result of long-standing GERD in 10-15% patients
- major cancer risk for esophageal adenocarcinoma
Peptic Esophageal Stricture
10% of patients who have reflux esophagitis
- ulceration stimulates fibrosis –> associated with NSAIDs
Solids Dysphagia
Intermittent –> lower esophageal ring
Progressive –> peptic stricture or cancer
