Abstract:
OBJECTIVETo evaluate anorectal dynamics, function and efficacy of ultralow rectal carcinoma patients undergone intersphincteric resection(ISR).
METHODSFrom January 2004 to August 2007, 30 patients with ultralow rectal carcinoma(2.5-4.0 cm distance from anal edge) underwent ISR. All the patients received anorectal manometry before and after operation. The postoperative anal function was evaluated by Williams continence standard and the treatment outcome was followed up.
RESULTSAfter ISR operation, anal resting pressure, maximum squeeze pressure and maximum tolerance volume of the rectum decreased significantly (all P<0.01) and restored gradually, but not to normal. The rectal anal inhibitory reflex disappeared in 27 patients(90.0%) and was not improved. According to Williams continence standard, 86.7%, 93.3% and 96.7% of patients obtained acceptable anal function in 3, 6, and 12 months after operation respectively. During follow-up of 12 to 44 months, all the patients were still alive and no patient developed pelvis or local recurrence, distant metastasis and anastomotic leakage. Fecal eczema of anus occurred in 10 patients, colonic mucosa prolapse in 2 patients and stenosis of anal canal in one patient.
CONCLUSIONISR for ultralow rectal carcinoma can not only attain radical treatment outcome, but also preserve anal sphincter.
