Background Postoperative death following large bowel surgery is relati
vely infrequent and no large study has analysed the cause of all death
s comprehensively and critically. Methods In-hospital deaths following
large bowel surgery in South-East Scotland were reviewed by independe
nt assessors. The audit was confidential but not anonymous. Independen
t assessors' reports were returned to consultants. Results The audit d
ocumented 187 deaths. The independent assessors noted an adverse event
in 78 patients (42 per cent), Twenty-six deaths (14 per cent) occurre
d following an anastomotic leak. A further 43 deaths (23 per cent) occ
urred because surgery was delayed (17) or there was undue delay in mak
ing the initial diagnosis (12) or recognizing a developing complicatio
n (14), Consultants operated on only half the patients classed as Amer
ican Society of Anesthesiologists grade IV or V, or undergoing a secon
d or subsequent operation. Conclusion Half the patients dying in this
study had identifiable deficiencies in their management. There is a cl
ear need for greater consultant input with critically ill patients.
