To ensure adequate length, it has been proposed that the superior mesenteric artery be divided and the right colon marginal vascular arcade be preserved. This study was designed to evaluate the influence of mesenteric lengthening techniques on the need for a stoma and on early outcomes after restorative proctocolectomy. METHODS: Records of patients who had a restorative proctocolectomy between January 1998 and October 2003 were reviewed. Patient and disease characteristics, operative techniques and findings, the need for a stoma, and postoperative complications were recorded. RESULTS: In one patient a restorative proctocolectomy was not possible. The remaining 220 patients were divided into two groups: Group A (inflammatory bowel disease; n = 123) and Group B (noninflammatory bowel disease; n = 97). Sixty-nine patients (31.4 percent) had major comorbidities. A length- ening technique was performed in 120 patients (54.5 percent) by dividing the ileocecal artery (n = 37) or the superior mesenteric artery (n = 88); 5 patients had only the marginal vascular arcade preserved. An ileostomy was not required in 116 patients (52.7 percent). In multivariate analysis, in Group B the only surgical variable influencing the need for an ileostomy was preservation of the marginal vascular arcade (50 vs. 14.7 percent; P < 0.0005). Complications occurred in 41 patients (18.6 percent), more frequently for those in Group A and for patients receiving steroids (23.6 vs. 12.4 percent, P = 0.012; 10.4 vs. 6.8 percent, P = 0.0172). CONCLUSIONS: The use of mesentery lengthening techniques allows a restorative proctocolectomy to be performed in almost all patients without increasing morbidity and may reduce the number of covering stomas. Because division of the ileocecal and/or superior mesenteric arteries may be required, preservation of the marginal vascular arcade is essential whenever possible.展开更多

METHODS: The medical records of 28 pediatric and 57 adult patients with ulcerative colitis who underwent total proctocolectomy and ileal J-pouch-anal anastomosis were reviewed. The relationship between the preoperative dose of glucocorticoids and major steroid-related complications, as well as the surgery variables, was evaluated. RESULTS: Significantly higher incidences of growth retardation, osteoporosis, glaucoma, and cataracts were noted in pediatric patients than in adult patients. In pediatric patients, major steroid-related complications occurred at a significantly lower preoperative total dosage of glucocorticoids/body weight (mg/kg) or preoperative total dosage of glucocorticoids/body surface area (mg/m2) than in adult patients. A similar surgical procedure was performed in both pediatric and adult patients. The presence of major steroid-related complications can lower a patient’s long-term quality of life. CONCLUSIONS: Evidence-based guidelines for the recommended dose of glucocorticoids according to body weight or body surface area are needed. To allow patients to feel well and maintain a good quality of life, early introduction of alternative treatments, including surgery, should be considered.展开更多
