Effect of surgical experience on the results of resection for oesophageal carcinoma.

From 1957 to 1976 oesophageal resection for carcinoma was performed in 1119 patients reported to the West Midlands Cancer Registry. The operations were performed on 581 patients by 127 surgeons who averaged three or less resections per annum (the 'occasional' group). These were compared with 538 patients (the 'frequent' group) whose resections were performed by four surgeons who averaged six or more resections per annum. Operative mortality was 39.4 per cent in the 'occasional' group and 21.6 per cent in the 'frequent' group (P less than 0.001). The age adjusted 5-year survival was 11.1 and 15.2 per cent respectively (P less than 0.05) but when the operative deaths were excluded there was no significant difference. We suggest that oesophageal resection for carcinoma should be performed only where there is an acceptably low operative mortality rate.
