BACKGROUND: The use of a protective stoma represents an important issue in colorectal surgery. Although evidence suggests that loop ileostomy may be superior, the optimal method for temporary decompression of colorectal anastomosis still remains controversial. Aim of this study was to make an evidence-based proposal for a tailored approach to the use of diverting colostomy or ileostomy.
METHODS: A retrospective analysis of all patients subjected to creation and closure of a diverting loop colostomy or loop ileostomy between May 2007 and November 2014 in our institution was performed. Early and late complications, mortality and morbidity, time between formation and closure of the stoma in respect to adjuvant chemotherapy and the length of hospital stay were assessed and compared between the two groups.
RESULTS: Outcomes of 167 patients (m=95; f=72) undergoing a loop colostomy (N.=130) or ileostomy (N.=37) were analyzed. The most frequent diagnosis was malignancy (64.1%), followed by abdominal emergency operations (18.6%) and complicated diverticular disease (17.4%). There was no mortality. Adjuvant chemotherapy (26.3%) resulted in delayed stoma reversal (P<0.001). Complications following construction of the stoma such as electrolyte disorder (P<0.001), renal insufficiency (P=0.048), and skin irritation (P=0.003) occurred significantly more often within the ileostomy group. Within the colostomy group, the rate of stoma prolapse (P=0.074) tended to be higher.
CONCLUSIONS: Both methods have advantages and disadvantages. Loop transverse colostomy could be the preferred technique for older patients to avoid electrolyte disorder and renal insufficiency. Further prospective trials with documentation of electrolyte metabolism and quality of life should follow.
