Background-The management of major colonic bleeding is problematic. A
proportion of patients require emergency surgery which is associated w
ith high morbidity and mortality. Percutaneous embolotherapy, previous
ly considered a high risk procedure in the colon, may provide an alter
native treatment in this group of patients. Aims-To assess the safety
and efficacy of embolotherapy in the treatment of life threatening col
onic haemorrhage. Patients and methods-Thirty eight patients with fres
h haemorrhage per rectum were referred for surgery because of failed c
onservative treatment. All underwent angiography; in 14 a bleeding sit
e or vascular abnormality was detected. A coaxial catheter was directe
d to the most distal bleeding artery and this was embolised with plati
num coils. Results-Detection of a bleeding site correlated with haemod
ynamic stability at the time of angiography (r=1 for a systolic blood
pressure less than 100 mm Hg). Bleeding sites or vascular abnormalitie
s were detected and embolised in 14 patients (37%). In 12/14 there was
immediate and sustained haemodynamic improvement; two continued to bl
eed and required emergency hemicolectomy (14%). Three developed ischae
mic complications (21.4%); these were managed conservatively and requi
red no intervention. The 30 day mortality was 7.1% in the embolotherap
y group and 10.5% in the overall group of 38 patients. Conclusion-Colo
nic embolotherapy for life threatening haemorrhage is an effective, re
latively safe procedure with a low incidence of major complications. I
ts use depends on the identification of a focal bleeding point or vasc
ular abnormality, which in turn depends on the haemodynamic stability
of the patient at the time of angiography.
