Temporary transverse colostomy vs loop ileostomy in diversion: A case-matched study

Hypothesis: For temporary fecal diversion, transverse colostomy (TC) has superior safety, but loop ileostomy (LI) has superior management qualities. Methods: Of patients with TC or LI seen between 1988 and 1997, 63 patients were matched for diagnosis, operative procedure, and date of surgery. The 2 groups were then compared for hospital/postoperative mortality and morbidity and stoma complications. Results: Mortality rates were 6.3% for the TC group and 1.6% for the LI group (P=.25) Morbidity rates for stoma creation and for stoma closure were 47.6% and 10% (P=.19), respectively, for the TC group, and 36.5% and 6.3% (P>.99), respectively, for the LI group. Most morbidity events were minor, and neither procedure-related nor other medical complications showed a significant difference between the groups. However, patients with a TC were significantly more likely to experience skin trouble around the stoma (TC vs LI, 15.9% vs 3.2%) and leakage around the stoma (TC vs LI, 12.7% vs 1.6%). Conclusions: Regarding safety, TC and LI should be considered equivalent options for temporary fecal diversion. We recommend further study comparing the 2 procedures with regard to patient perception and quality of life.
