[The significance of omentum-plasty for early detection of local recurrence following abdomino-perineal rectum amputation in cancer].

In a prospective study activated in October 1986 feasibility of omentoplasty after abdomino-perineal resection for cancer and implications of this procedure on early diagnosis of local recurrence were assessed. In 22 of 32 patients abdomino-perineal resection was completed by obliteration of the pelvi-perineal deadspace with pedicled omentum. CT-scans 6 months and 1 year postoperatively were analyzed in relation to diagnosis or exclusion of local recurrence. In 6 patients (27%) local recurrence was diagnosed in CT-scan and confirmed clinically (no false positive result). In 11 patients (50%) local recurrence could be excluded with high probability. In 5 patients (23%) uncertainty remained about exclusion of local recurrence.
