Outcome in patients with colorectal cancer managed by surgical trainees

Background: The surgeon is an important variable that influences outcome following colorectal cancer surgery. Operative training of suitable quality and quantity is essential if intersurgeon variation is to be reduced. The aim of this study was to examine the outcome of colorectal cancer surgery when a high proportion of the operations were performed by trainee surgeons. Methods: A prospective 7-year (1989-1996) audit of 306 consecutive colorectal cancers referred to a single general surgeon with a colorectal interest was carried out. The outcome (anastomotic leakage, 30-day mortality rate, local recurrence and cancer-related survival) of operations performed by the consultant was compared with that of his trainees. Results: Some 245 (92.5 per cent) of 265 patients undergoing laparotomy had a resection. Seventy (28.6 per cent) and 67 (27.3 per cent) of operations were performed by supervised and independent trainees respectively. There was no difference between the consultant, supervised and independent trainees for 30-day mortality rate (6.5, 6 and 4 per cent respectively), clinical anastomotic leakage rate (9, 2 and 5 per cent) and local recurrence rate (2, 3 and 7 per cent). There was no difference between the three groups for adjusted 5-year disease-related survival rates. Conclusion: Properly supervised trainees can resect a high proportion of colorectal cancers without compromising immediate outcome or long-term survival.
