Background: The aims of this study were to evaluate the prevalence of invas
ive cancer in patients with high-grade dysplasia in Barrett's oesophagus an
d to verify whether a second endoscopy with multiple biopsies could improve
the accuracy of preoperative diagnosis. In addition, the mortality, morbid
ity and survival rates in patients with high-grade dysplasia having oesopha
geal resection were recorded.
Methods: Fifteen patients were observed from 1982 to 1998; the first seven
patients were offered primary oesophageal resection after diagnosis. The ot
her eight patients underwent a second endoscopy with a median of 12 biopsie
s examined. All later underwent oesophageal resection.
Results: Invasive adenocarcinoma was found in five patients, with a minimal
difference between the first and second periods (two of seven versus three
of eight). There were no perioperative deaths. Early morbidity was observe
d in eight patients and late morbidity in four. The actuarial survival rate
was 79 per cent at 5 years. The Karnofsky status was unchanged from preope
rative values in 13 of 15 patients after a median follow-up of 46 months.
Conclusion: These patients with high-grade dysplasia had a 33 per cent prob
ability of harbouring invasive oesophageal carcinoma but even a second endo
scopy failed to identify patients with invasive tumour. Oesophagectomy was
performed with no deaths and remains a rational treatment in patients fit f
or surgery.
