They secrete peptides and neuroamines that may cause carcinoid syndrome. However, many are clinically silent until late presentation with major effects. Initial treatment aims to control carcinoid syndrome with somatostatin analogs. Even if there is metastatic spread, surgical resection of the primitive tumor should be discussed in cases of retractile mesenteritis, small bowel ischemia or subocclusive syndrome in order to avoid any acute complication, in particular at the beginning of somatostatin analog treatment. The choice of treatment depends on the symptoms, general health of the patient, tumor burden, degree of uptake of radionuclide, histological features of the tumor, and tumor growth. Management strategies include surgery for cure (which is rarely achieved) or for cytoreduction, radiological interventions (transarterial embolization or radiofrequency ablation), and chemotherapy (interferon and somatostatin analogs). New biological agent and radionuclide targeted therapies are under investigation. Diffuse and non-evolving lesions should also be simplymonitored. Finally, it has to be emphasized that it is of the utmost importance to enroll these patients with a rare disease in prospective clinical trials assessing new therapeutic strategies.展开更多

METHODS: Sixty six patients underwent laparoscopic total colectomy for inflammatory bowel disease (IBD) (13) and other diseases (53). Data on demographics, pre and post-operative outcomes were collected prospectively.RESULTS: Mean operative time was 4.5 h. Conversion rate was 13.6%. Total colectomy performed for IBD was associated with a signifi cantly higher anastomotic leak rate (23.1% vs 1.9%, P < 0.05). On univariate analysis, hand sewn anastomosis and treatment with more than 20 mg of prednisolone for at least 3 mo was associated with a higher anastomotic leak rate (P < 0.05). No signifi cant difference was found in return of gut function and overall morbidity between disease groups. CONCLUSION: Laparoscopic total colectomy is feasible and outcomes are equivalent whatever the indica- tion, except for anastomotic leak rate which is higher for patients with IBD.展开更多
