CANCER OT THE OESOPHAGUS

Share it:



Descriptive Definition of Cancer of The Oesophagus
·         The oesophagusggt is a muscular tube about 22.5 cm long equipped with both circular and longitudinal muscle fibers. It conducts the ingested material into the stomach, wavelike contractions of its wall expressing its contents into the gastric reservoir
·         Cancer also known as carcinoma is a common term for neoplasm or tumours that are malignant
·         It is an abnormal growth of cells which tend to proliferate in an uncontrolled way and in some cases to metastasize (spread).
·         Its cause is not yet known

Predisposing Factors of Cancer of the Oesophagus

·         Predisposing factors are:
o   Chronic trauma due to frequent use of alcohol, tobacco, spicy foods, and poor oral hygiene


Signs And Symptoms Of Cancer Of The Oesophagus
Signs and symptoms
·         Intermittent and increasing difficult in swallowing first solid and later even liquids
·         Regurgitation of food and saliva
·         Haemorrhage may occur
·         Loss of weight and strength due to starvation

Later signs
·         Sub-sternal pain
·         Hiccough
·         Respiratory difficulty
·         Foul breath
Diagnosis is confirmed by:
·         Oesophagogram
·         Hystologic examination of esophageal washings and biopsy
·         Barium x-ray
·         Esophagoscopy
·         Bronchoscopy can be done to rule out involvement of the trachea and possibility of removal

Management and Nursing Care of a Patient with Cancer of the Oesophagus
Management and Nursing care
·         Surgical removal of the growth
·         The portion of the esophagus that contain the growth is removed followed by an esophagostrotomy
·         Radiation is done either after surgery or before surgery.
·         Gastrotomy a palliative procedure which is done if the growth is inoperable to permit the administration of food and fluids.


Preoperative nursing care
·         Administer high caloric and high protein diet in liquid or solid form
·         Encourage good oral hygiene as regurgitation leaves an unpleasant smell in the mouth
·         Acquaint the client with the equipment he will find after waking up from anaethetic such as chest drainage, nasogastric suction, parenteral fluids and sometimes a gastrostomy tube.
·         Provide the general preoperative care
Post operative nursing care
·         Give the general postoperative care and care as for any patient who has undergone chest operation
·         When patient starts taking oral feeds observe for regurgitation and dyspnea
·         Check vital signs especially temperature as it elevates if there is seepage of fluid through the operative site into the mediasternum.
·         Start with semisoft food, soft and then regular foods.
·         Observe for dyspnea if a part of stomach has been drawn into the chest.
·         Alleviate dyspnoea by frequent feedings of small amounts and by the patient remaining upright for 2 hours after eating.

Prognosis Incase of Cancer of the Oesophagus
Prognosis
·         It is good if detected and removed early and the continuity of the digestive system is easily maintained.
·         High mortality rate is because:
·         In older patients the incidence of pulmonary and cardiovascular disorder is high.
·         Before significant symptoms occur the tumour has already invaded surrounding structures.
·         The malignancy tends to spread to nearby lymph nodes, the heart and the lungs
45-80% of operated cases showed evidence of metastasis


Descriptive definition and predisposing factors of cancer of the stomach

The stomach is a distensible pouch situated between the oesophagus and the duodenum and it distends to become a large hollow receptacle capable of holding about 1500 ml. during a meal
It is a malignant growth of the gastric which affects mostly persons over 40 years and occasionally in younger people
Causes not yet known but heredity is a predisposing factor.

Signs and Symptoms of Cancer of the Stomach
Signs and symptoms
·         Early symptoms not easy to be recognized because most of the tumors start on the lesser curvature where they cause little disturbance to the gastric functions
Most early signs are:
·         Progressive loss of appetite
·         The appearance of, or change in gastrointestinal symptoms.
·         Appearance of blood in the stools
·         Vomiting or a feeling of fullness immediately following a meal if it causes obstruction in the cardiac orifice
·         If the growth is near the pylorus vomiting becomes a prominent symptom.
·         Vomiting of coffee ground vomitus, the blood that leaks slowly from the cancer.
·         Gastric juice does not reveal free hydrochloric acid
Later signs are:
·         Weight loss
·         Weakness
·         Anemia
·         Jaundice
·         Pain occurs very late in most cases when there is no opportunity of curing it.
·         Since metastasis frequently occurs before warning signs, dyspepsia of more than 4 weeks duration in any person over 40 years calls for complete examination of the gastrointestinal tract.
Management and Nursing Care of a Patient with Cancer of the Stomach
Management and Nursing care
·         The only successful treatment is removal of the tumour
·         The patient can be cured if the tumour is localized only in the stomach
·         If it has spread to other organs, effective palliation may be obtained by resection of the tumour.
Preoperative care
Similar to any abdominal surgery
·         Take blood for grouping and cross match
·         Correct the anaemia
·         Pre and post operative chest exercise to avoid pulmonary complications
·         Instruct the patient to stop smoking
·         Correct fluid and electrolyte balance
·         The stomach should be emptied at least 3 hours preoperatively
·         If there is  pyloric stenosis the stomach is emptied the night of the operation
·         If the pyloric stenosis is severe the stomach is aspirated for several days
·         Pass  a Nasogastric tube and leave it insitu

Nursing Care of a Patient following Surgery
Partial Resection
·         Place patient in a modified Fowlers position when awake for easy drainage of the stomach
·         Give analgesics as prescribed to allow for deep breathing and productive coughing preventing pulmonary complication
·         Report any excessive bleeding from the Nasogastric drainage.
·         Give nothing per oral
·         Clean the nostrils with an applicator moistened in water
·         Give mouth washes frequently
·         Apply cool water sponges to the mouth rather than ice which intensifies thirst
·         Give parenteral fluid to meet fluid and nutritional needs as well as compensating for the fluid lost in the drainage and vomitus
·         Keep an intake and output chart.
·         After removal of the Nasogastric tube
·         Restrict fluid per oral for several hours
·         Start with small amounts of fluids sparingly
·         Warm weak tea with sugar is preferred
·         Then bland food which should be added gradually till patient can take 6 small meals a day and drink 120 ml. of fluid between meals.
·         If the patient regurgitates he may be eating too fast or too much. If there is gastric retention reinstitutes Nasogastric suction.
·         Encourage the patient to get out of bed on the first postoperative day.
·         Increase ambulation daily
·         Dressing can be reinforced if necessary
·         Report any undue drainage saturation.

Total Resection
Care will be as for a patient postoperative abdominal surgical care and post operative chest surgical care.
Remove the Nasogastric tube as soon as there bowel sounds resume
Give clear fluids and small feeds after 2 or 3 days if the temperature is normal that is no anastomosis leakage.
Because normal digestion is disturbed the patient will need nutritional supplementation with vitamin and minerals.
Give iron and vitamin B12

Post Operative Complications and at Home Regimen
Post operative complication
·         Shock
·         Vomiting
·         Hemorrhage
·         Pulmonary complications
·         Dumping syndrome
·         Diarrhea
·         Vitamin B12  deficiency
At home Regimen
·         Advice patient to continue increasing the size of his meals and reduce the number until he can take three regular meals in about 6 months
·         Gradual return to his activities according to his ability may take about 3 months
·         Recommend adequate rest periods
·         Follow up visits where his questions may be answered should be given
·         Dietary consultation may be required
