4. TUMOURS
4.1 LEIOMYOMA
This is the most
common benign tumour of the
oesophagus. They
occur in equal frequency in males and females between the
ages of
20-50 years. The majority of these intramural tumour occur
in
the middle and lower thirds of the oesophagus.
They present with
dysphagia small (<5 cm="" span="" style="mso-spacerun: yes;">
symptoms.
Obstruction and regurgitation occurs in large tumours.
TREATMENT
The tumour is excised through a thoracotomy (left for
lower third
and right for
middly third). The
longitudinal fibres of
oesophagus
split and the tumours dissected
out -
leaving the
submucosa intact.
The longitudinal fibres are stiched.
4.2 HEMANIGIOMAS
These
constitute 2-3% of all benign
tumours and may
remain
symptomless. They
may sometimes cause successive hematemesis.
Laser therapy
through the endoscope provide effective
means of
treatment.
