A total of 704 patients with symptomatic prolapsed haemorrhoids were o
perated on over a 24-month period. Overall, 500 underwent elective hae
morrhoidectomy for symptomatic prolapsed haemorrhoids and 204 emergenc
y haemorrhoidectomy for acutely prolapsed, thrombosed or gangrenous ha
emorrhoids. The mean age was 43 (range 16-80) years in patients underg
oing elective surgery and 42 (range 20-86) years in those receiving em
ergency procedures. After elective surgery 27 patients (5.4 per cent)
had an episode of secondary haemorrhage; ten (2.0 per cent) required b
lood transfusion and six (1.2 per cent) needed surgical haemostasis. A
fter emergency surgery, ten patients (4.9 per cent) developed secondar
y haemorrhage; four (2.0 per cent) required blood transfusion and two
(1.0 per cent) surgical haemostasis. Twelve patients (5.9 per cent) de
veloped anal stenosis after an emergency procedure compared with 15 (3
.0 per cent) after elective operation. None of the patients in either
group developed portal pyaemia. After elective surgery 26 patients (5.
2 per cent) developed a degree of incontinence (eight to flatus, 15 to
liquids, three to solids) as did nine patients (4.4 per cent) after e
mergency procedures (three to flatus, five to liquids, one to solids).
Recurrent haemorrhoids were found in 38 patients (7.6 per cent) after
elective surgery and in 14 (6.9 per cent) after an emergency procedur
