Q. 1

H type tracheo-esophageal fistula occur in

 A

<1%

 B

5%

 C

8%

 D

12%

Ans. B

Explanation:

The H type fistula occurs in 8% of cases.

  1. Type A
  • Oesophageal atresia without TOF (8%)
  • Both segments communicate with trachea.

       2. Type B

  • Oesophageal atresia with proximal TOF (1%)
  • Blind proximal segment of oesophagus connects with trachea by fistula.
  • Distal end is blind

       3. Type C

  • Oesophageal atresia with distal TOF (84%)
  • Distal segment of oesophagus is connected with trachea by fistula.

       4. Type D-

  • Oesophageal atresia with proximal & distal TOF.
  • Both ends are blind & no communication (3%)

       5. Type E-

  • TOF without oesophageal atresia (4%)
  • H- type

Q. 2

Malignant tracheo-esophageal fistula best treated with

 A

Radiotherapy

 B

Chemotherapy

 C

Stenting

 D

Surgical correction

Ans. D

Explanation:

Ans. is ‘d’ i.e. Surgical correction 

  • Malignant tracheo-esophageal fistula is an uncurable condition. The best that can be done for these patients to offer them palliative therapy. Stenting, tube or Surgical bypass can be used to relieve the patient. Radiotherapy is not used as an initial therapy for patients of carcinoma with tracheobronchial involvement as it may create a fistula or worsen the existing one. Chemotherapy has no role in palliative treatment.
  • Surgical bypass is the best treatment for malignant tracheo-esophageal fistula.

CSDT writes :

–   “Patients with malignant tracheoesophageal fistulas cannot be cured, but palliation is a realistic goal. Aspiration of saliva and swallowed liquids produce incessant coughing, and dysphagia is usually pronounced. The best treatment is probably substernal gastric bypass with a cervical esophagogastric anastomosis. Both ends of the thoracic esophagus are closed. The fistula is usually large enough to accommodate the small amount of esophageal secretion. Celestin tubes are of little value.”
