Sumario:BACKGROUND: Given the risks associated with urgent colectomy for large bowel obstruction, preoperative colonic stenting has been utilized for decompression and optimization prior to surgery. This study examined national trends in the use of colonic stenting as a bridge to resection for malignant large bowel obstruction and evaluated outcomes relative to immediate colectomy. METHODS: Adults undergoing colonic stenting or colectomy for malignant, left/sigmoid large bowel obstruction were identified in the 2010–2016 Nationwide Readmissions Database. Patients were classified as immediate resection (IR) or delayed resection (DR) if undergoing colonic stenting prior to colectomy. Generalized linear models were used to evaluate the impact of resection strategy on ostomy creation, in-hospital mortality, and complications. RESULTS: Among 9,706 patients, 9.7% underwent colonic stenting, which increased from 7.7 to 16.4% from 2010 to 2016 (p < 0.001). Compared to IR, the DR group was younger (63.9 vs 65.9 years, p = 0.04), had fewer comorbidities (Elixhauser Index 3.5 vs 3.9, p = 0.001), and was more commonly managed at high-volume centers (89.4% vs 68.1%, p < 0.001). Laparoscopic resections were more frequent among the DR group (33.1% vs 13.0%, p < 0.001), while ostomy rates were significantly lower (21.5% vs 53.0%, p < 0.001). After risk adjustment, colonic stenting was associated with reduced odds of ostomy creation (0.34, 95% confidence interval 0.24–0.46), but similar odds of mortality and complications. CONCLUSION: Colonic stenting is increasingly utilized for malignant, left-sided bowel obstructions, and associated with lower ostomy rates but comparable clinical outcomes. These findings suggest the relative safety of colonic stenting for malignant large bowel obstruction when clinically appropriate.
