Efficacy and Follow-up of Segmental or Subtotal Colectomy in Patients With Colitis-Associated Neoplasia.

The historical approach to neoplasia in the setting of chronic colitis was to perform a total proctocolectomy. Recent consensus and society guidelines ^1-3 suggest that when dysplastic lesions can be removed endoscopically, continued surveillance is appropriate. This is based on improvements in optical technologies and the low risk of metachronous colorectal carcinoma in these patients. ^4-6 We hypothesized that if a lesion was completely removed surgically and followed up endoscopically, metachronous colorectal carcinoma would be a rare occurrence. Thus, segmental resection may be offered as a definitive surgery in patients with chronic colitis and localized colorectal neoplasia in whom endoscopic resection is not feasible. Retention of the distal colon/rectum is expected to result in an overall improved quality of life compared with permanent ileostomy or an ileoanal J-pouch. Here, we report our experience and follow-up evaluation of segmental resections for preoperative neoplasia in patients with Crohn's disease (CD) or ulcerative colitis (UC).
