A new ultimate anus-preserving operation for extremely low rectal cancer and for anal canal cancer
2003
To avoid permanent colostomy, we perform a new ultimate
anus preserving operation for extremely low rectal cancer or for
anal canal cancer. According to our pathologic study, two
different removal methods of anal canal were theoretically
considered. One is internal sphincter resection (ISR method),
and the other is both deep-superficial external sphincter and
internal sphincter resection (ESR method). Six patients received
ISR and ten patients ESR. No severe intraoperative complications
occurred and the postoperative course was uneventful. All
patients receiving ISR had excellent anal function without
soiling. Some patients receiving ESR sometimes complained of
night soiling but satisfied the anus preservation. The median
follow-up was 15 months, (range, 3–28 months). We had
recurrences in two female patients receiving ISR. One had
para-aortic and lateral lymph node recurrences without
anastomotic recurrence. She underwent lateral and para-aortic
lymphadenectomy, but died of lung metastasis, regardless of
intensive chemotherapy. Another had pelvic recurrence with
abdominal dissemination. She underwent abdominoperineal
resection and is alive with pelvic re-recurrence. ISR and ESR
are excellent procedures for anus preservation, but ISR needs a
strict indication.
