Comparative outcomes between palliative ileostomy and colostomy in patients with malignant large bowel obstruction
2019
Objectives: Palliative stoma creation should be considered in patients at high risk of colonic metallic stent failure. However, it is unclear whether ileostomy or colostomy is superior. This study compared short-term outcomes between palliative ileostomy and colostomy. Methods: We identified 82 patients with malignant large bowel obstruction, caused by various advanced cancers, between January 2005 and December 2016. We compared short-term outcomes between the ileostomy group (n = 33) and the colostomy group (n = 49). Results: For all 82 patients, clinical success was achieved. Three patients with ileostomy died within 30 days of ostomy formation. The ileostomy group had statistically significant differences in median operative time (113 vs. 129 minutes, p = 0.045) and blood loss (8 vs. 40 g, p = 0.037) in comparison with the colostomy group. No statistically significant differences were observed in the surgical complications (30.3 vs. 38.8%, p = 0.431), in the median period to oral intake (3 vs. 4 days, p = 0.335) and in the hospital stay after surgery (32 vs. 27 days, p = 0.509) between the two groups. Overall stoma-related complications occurred in 27 (32.9%) patients. Stoma-related complications occurred more frequently in the ileostomy group (16/33 vs. 11/49 patients, p = 0.014). High output stoma (6 patients) and irritation (5 patients) occurred more frequently in the ileostomy group. Conclusions: Palliative colostomy is superior to ileostomy due to fewer stoma-related complications. When ileostomy is required, aggressive interventions for high output stomas should be implemented.
