Common Gastrointestinal
Symptoms in Palliative Patients
• Oral discomfort
• Dysphagia
• Nausea and vomiting
• Hiccups
Objectives
• To acquire knowledge of current evidence in
managing GI symptoms
• To recognize oral discomfort and hiccups as
treatable symptoms
• To apply principles of management of GI symptoms
to clinical practice
Causes of Oral discomfort:
Definitions
• Xerostomia: Dryness of the mouth resulting from
diminished or arrested salivary secretion
• Dysgeusia: An impairment or dysfunction of the
sensation of taste
• Stomatitis: The inflammation of the mucous lining
of any structures of the mouth, which may involve
the cheeks, tongue, gums, lips, and roof or floor of
the mouth
• Mucositis: inflammation of a mucous membrane
The Free Dictionary By Farlex
Causes of Oral discomfort
• Oral pain: angular stomatitis, dental caries, poorly
fitting dentures, XRT or chemo induced stomatitis or
mucositis, candidiasis, burning mouth syndrome
• Xerostomia: related to cancer (head and neck),
dehydration, radiation, drug therapy
(anticholinergic, psychotropic, opioid,
cardiovascular)
• Dysgeusia: sinusitis or other infection, xerostomia,
medications (antidepressants, HIV meds,
chemotherapy), vitamin or mineral deficiency (zinc)
Denture stomatitis
• Definition: oral candidiasis that can occur
in healthy adults wearing dentures
• May present as bleeding, swelling,
burning sensation, xerostomia, or
cacogeusia
• 35-50% of people wearing complete
dentures
Altarawneh et al, “Clinical and Histoligic Findings of Denture Stomatitis as Related
to Intraoral Colonization Patterns of Candida albicans, Salivary Flow, and Dry
Mouth,”J Prosthodont, 2012
Management of Oral
Discomfort
Xerostomia treatment options
• Salivary substitute or oral gel every 1-2 hours or sugarfree
gum
• Malic acid 1% spray
• Oral care: encourage family members to keep patient’s
mouth moist (oral swabs to bedside)
• Increase liquid PO intake; try frozen juices, popsicles, ice
chips, Resveratrol
• Pilocarpine 5 to 10 mg three times daily (watch for
respiratory secretions or diarrhea)

Induced by Antihypertensive Drugs,” Med Oral Patol Oral Cir Bucal 2012
Furness S et al, “Interventions for Management of Dry Mouth: Topical Therapies,”
Cochrane Database Syst Rev 2011
ALTENS
• Acupuncture-like Transcutaneous Electric Nerve Stimulation
• 47 patients with cancer of the head and neck who were 3 to24
months from completing radiotherapy (mean age 60 years)
with xerostomia
• Patients received twice weekly ALTENS sessions over 12 weeks
• Six month Xerostomia-Related Quality of Life Scale
(XeQOLS) scores showed 86% of patients received a positive
treatment response
• Now entering Phase 3 studies

Combination mouthwash preparations with:
•
•
•
•
•
•
Diphenhydramine
Lidocaine
Loperamide

Receiving Treatment,” Cochrane Database of Syst Rev, October, 2010
Laser Therapy in Mucositis
• 16 children (mean age 9.4 years) with
chemotherapy-induced mucositis
• All children treated with GaAIAs diode laser with
830 nm wavelength, repeated every 48 hours until
healing of lesion occurred
• On average 2.5 treatments in a period of 1 week
were sufficient to heal the lesion; pain relief noted
immediately after each treatment

Dysphagia
• Definition: Difficulty in swallowing or inability to
swallow
The Free Dictionary by Farlex
Dysphagia
• Oropharyngeal dysphagia
• Obstructing esophageal lesions
• Esophageal dysmotility (neuromuscular,
autoimmune)
• Cognitive impairment
Oropharyngeal Dysphagia
• Upright positioning in bed, sitting at a table for
meals
• Changing consistency of food (soft, pureed,
thickened liquids)
• Careful hand feeding by caregivers
• Videofluoroscopy and Speech therapy consultation
Deane K et al, “Dysphagia occurs frequently in Parkinson's disease although patients
themselves may be unaware of swallowing difficulties. Speech and language therapists
in conjunction with nurses and dietitians use techniques that aim to improve swallowing,”
Cochrane Database of Syst Rev, Jan 2001.
Esophageal obstruction
• Surgical resection or laser ablation
• Placement of esophageal stent (SEMS)
• Placement of gastrostomy tube
• Help family cope with anxiety about patient’s poor
PO intake
• Clarify goals of care
• Consider artificial nutrition and hydration
Larssen L et al, “Long-term outcome of palliative treatment with self-expanding metal
stents for malignant obstructions of the GI tract,” Scand J Gastroenterol, Oct 2012
Artificial Nutrition and
Hydration (ANH)
•
Feeding tubes: nasogastric or percutaneous endoscopic
gastrostomy tube
• First PEG in 1980
• Research studies indicate
events with PEG
•
Total parenteral nutrition
• Rarely beneficial for cancer patients due to metabolic derangements,
cachexia syndrome
• Benefit for post-surgical oncology patients expected to recover bowel
function
• Adverse effects: infections, liver failure, thrombosis
•
IV hydration or subcutaneous hypodermoclysis

Nausea and Vomiting
Definitions
• Nausea: A feeling of sickness in the stomach
characterized by an urge to vomit
• Vomit (v): To eject part or all of the contents
through the mouth, usually in a series of
involuntary, spasmic movements
The Free Dictionary by Farlex
Nausea and Vomiting
Diagnostic Work up
• Blood chemistries: calcium, sodium, BUN, creatinine,
bilirubin
• Drug levels (theophylline, digoxin, anti-epileptic drugs)
• Neuroradiologic imaging to evaluate for sources of
increased intracranial pressure or brainstem causes or
vertigo and nausea
• Abdominal imaging
• HIDA scan
Nausea from GI tract
•

compression…………………

consult
Pullens B and van Bentham PP, “Intratympanic gentamycin for Meniere’s disease or
syndrome,” Cochrane Database of Syst Rev 2011
Nausea due to bowel
obstruction
• Therapeutic goal to manage symptoms in terminal patients
(pain, cramps, nausea, emesis)
• Dexamethasone (may relieve malignant bowel obstruction)
• Transdermal scopolamine (slows gut, causes dry mouth,
urinary retention, confusion)
• Glycopyrrolate (slows gut, causes dry mouth, urinary
retention, confusion)
• Hyoscyamine (slows gut, causes dry mouth, urinary retention,
confusion)
• Octreotide (expensive, reduces gut secretions)
Hiccups
• Definition: involuntary, intermittent, spasmodic
contraction of the diaphragm and intercostal
muscles. Muscle contraction results in a sudden
inspiration and ends with abrupt closure of the
glottis, thereby generating the characteristic ‘hic’
sound. Hiccups often occur with a frequency of 4 to
60 per minute, remaining relatively constant in a
given individual.
Lembo A, “Overview of hiccups”, Up to Date 2011
Hiccups
• Hiccup bout: lasts up to 48 hours
• Persistent hiccups: continues after 48 hours up to 1
month
• Intractable hiccups: continue longer than 1 month
Pathophysiology of hiccups
•
Neural pathways of the
hiccup reflex arc:
• Afferent limb of phrenic and
vagus nerves and sympathetic
chain
• Central mediator
• Efferent limb of phrenic nerve,
nerve connections to glottis and
inspiratory intercostal muscles
•
Thought to involve the
medulla oblongata, reticular
formation of the brainstem,
nuclei of phrenic nerve, and
hypothalamus
