TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Perineal pressure ulcers are a common and devastating complication for paralyzed or chronically bedridden patients. Controversy exists on the benefit of fecal diversion for the treatment and prevention of these ulcers. This study compared outcomes in bed-bound patients with pressure ulcers who electively underwent fecal diversion with those who did not.', 'A retrospective review was performed on all disabled patients who underwent surgery for medically intractable pressure ulcer from 1993 to 2001. Charts were divided into the colostomy group or noncolostomy group. Recurrence rates, healing times, morbidity and mortality, and number of reoperations were calculated for each group. Additionally, stoma patients were interviewed for quality of life assessment.', 'Sixty-seven patients were treated during the study period (colostomy, n = 41; noncolostomy, n = 26). The majority of colostomies were performed laparoscopically, with a 9.7 percent incidence of postoperative complications. The ulcer recurrence rate was lower in the treated colostomy group (43 percent) compared with the noncolostomy group (69 percent; P < 0.05). In addition, noncolostomy patients had longer healing times (7 vs. 3 months; P < 0.05), and this group required more ulcer operations than the stoma patients did. Quality of life and bowel care were much improved by the colostomy.'] Does elective stoma construction improve outcomes in medically intractable pressure ulcers?
