  • Title: Surgery for neoplastic changes in ulcerative colitis--can limited resection be justified? Outcome for patients who underwent limited surgery.

    Abstract:
    BACKGROUND: Patients with ulcerative colitis (UC) are at an increased risk of developing colorectal cancer (CRC). The aim of this study was to investigate the outcome for the patients who underwent limited resection of the colon and/or rectum instead of panproctocolectomy (PPC), with special attention to those with neoplastic changes. METHODS: Since 1977, all known patients with UC from our catchment area have been included in our surveillance programme. A total of 210 patients with UC have been followed up with regular colonoscopies and biopsies. Indications for surgery were severe therapy-resistant disease (TRD), high-grade dysplasia (HGD), CRC or repeated findings of low-grade dysplasia (LGD). Patient compliance was excellent. RESULTS: Fifty-one patients were operated on. In 29 of these patients, PPC was performed initially. At the end-point of the study, additionally seven patients had been radically operated on and three more patients planned to undergo such an operation. Accordingly, 22 patients had their first operation performed as a resection of either a part of or the whole colon or rectum. In this group, there were four patients diagnosed with CRC and three with dysplasia-associated lesion or mass (DALM). One of them died 6 months after surgery because of disseminated CRC, whereas the other patients were alive at the end-point of the study. One of these seven patients with CRC or DALM had at end-point been radically operated on and two patients were awaiting such a procedure (in two patients because of LGD and in one patient because of TRD). Six of the patients who had a colorectal resection performed on the indication of TRD were radically operated later on, five of them because of relapsed TRD and one patient because of LGD in the remaining rectal mucosa. Twenty-one patients gained a mean of 9.4 years with presumably better bowel function, from undergoing a limited resection instead of PPC. None of the patients who underwent a colonic and/or rectal resection died because of CRC or metachronous cancer in their remaining colon or rectum. CONCLUSION: The results of this study indicate that a limited resection of the colon and/or rectum in patients with UC, which requires surgical intervention increases the time with presumably better bowel function and may therefore be an alternative to PPC without increased risk of dying from CRC. This is dependent on the flexibility of the medical service and patient compliance.
