Abstract
Purpose
Defunctioning loop ileostomy has been reported to reduce symptomatic anastomotic leakage after rectal cancer surgery; however, stoma outlet obstruction (SOO) is a serious postileostomy complication. We, therefore, explored novel risk factors for SOO in defunctioning loop ileostomy after rectal cancer surgery.
Methods
This is a retrospective study that included 92 patients who underwent defunctioning loop ileostomy with rectal cancer surgery at our institution. Among them, 77 and 15 ileostomies were created at the right lower abdominal and umbilical sites, respectively. We defined the output volumeMAX as the maximum output volume the day before the onset of SOO or—for those without SOO—that was observed during hospitalization. Univariate and multivariate analyses were performed to evaluate risk factors for SOO.
Results
SOO was observed in 24 cases, and the median onset was 6 days postoperatively. The stoma output volume in the SOO group was consistently higher than that in the non-SOO group. In the multivariate analysis, the rectus abdominis thickness (p < 0.01) and output volumeMAX (p < 0.01) were independent risk factors for SOO.
Conclusion
A high-output stoma may predict SOO in patients with defunctioning loop ileostomy for rectal cancer. Considering that SOO occurs even at umbilical sites with no rectus abdominis, a high-output stoma may trigger SOO primarily.
