Abstract
AIMS: To study the frequency with which unresectable disease was identified on pre-operative staging investigations in patients with oesophago-gastric carcinoma, and to audit whether a staging protocol had reduced the rate of exploratory surgery. METHODS: Ninety-eight patients with oesophageal carcinoma, 89 patients with adenocarcinoma of the gastro-oesophageal junction (GOJ) and 68 patients with gastric carcinoma were staged according to a protocol of computerised tomography, laparoscopy and endoscopic ultrasound. RESULTS: The frequency with which each investigation identified unresectable disease was as follows: (a) computerised tomography-oesophagus 12/67, GOJ 13/58, stomach 10/60; (b) laparoscopy-oesophagus 3/22, GOJ 5/45, stomach 8/23; and (c) endoscopic ultrasound-oesophagus 15/55, GOJ 3/30. By tumour location, rates of exploratory surgery were 1/18 for the oesophagus, 12/35 for the GOJ and 4/42 for the stomach. All of the staging failures in patients with GOJ carcinomas related to posterior tumour extension into the lesser sac. CONCLUSIONS: Staging investigations precluded resection in one-third of patients, the greatest yield being for laparoscopy in gastric carcinoma. In spite of this, 18% of patients undergoing surgical intervention underwent exploratory surgery alone, notably patients with GOJ carcinoma.
