Abstract: | PURPOSE: Total anorectal reconstruction with a double dynamic graciloplasty was performed after abdominoperineal reconstruction
(APR) for low rectal cancer. In four patients an additional pouch was constructed to improve neorectal motility and capacity.
The aim of this study was to evaluate the results in the first 20 patients and to report on the preliminary results of patients
with an additional pouch. METHODS: Twenty patients with a mean age of 52 (range, 25–71) years and a rectal tumor at a mean
of 3 (range, 0–5) cm from the anal verge were treated. In 14 patients the Miles resection, colon pull-through, and construction
of a neosphincter were performed in one session. Six patients had the double graciloplasty at an average of 4.1 (range, 1.1–8.8)
years after APR. In four patients a pouch was constructed with an isolated segment of distal ileum. RESULTS: After a mean
follow-up of 24 (range, 1–60) months after APR, none of the patients developed local recurrence, whereas four patients developed
distant metastasis. Fifteen of 20 patients were available for evaluation, and 5 patients were still in training. Of these
15 patients, 8 patients were continent (53 percent), 2 patients were incontinent, and in 5 patients the perineal stoma was
converted to an abdominal stoma. Failures were attributable to necrosis of the colon stump (n=2) and incontinence (n=3). At
26 weeks mean resting pressure was 44 (standard deviation (SD), 28) mmHg, and mean pressure during stimulation was 90 (SD,
46) mmHg at a mean of 35 (SD, 1.2) volts at 52 weeks. Mean defecation frequency was three times per day (range, 1–5). Of the
eight patients who were continent, six used daily enemas. Mean time to postpone defecation was 11 (range, 0–30) minutes. CONCLUSION:
In experienced hands, the double dynamic graciloplasty is an oncologically safe procedure that can have an acceptable functional
outcome in a well-selected group of patients. However, to improve the outcome, further modifications will be necessary. So
far, the addition of a pouch has not resulted in improved outcome.
