Background
Currently, the relationship between temporary stoma reversal and the severity of postoperative complications (POCs) after the index surgery based on the Clavien–Dindo classification has not yet been explored.
Methods
From July 2010 to June 2016, 380 patients undergoing sphincter-preserving surgery for rectal cancer with a temporary stoma in our hospital were included. Temporary stoma nonclosure rates, disease-free survival rates, and overall survival rates were estimated utilizing the Kaplan–Meier method.
Results
Of all the 380 patients, primary stomas were created in 335 patients and secondary stomas in 45 patients. After the index surgery, 36.6% (139/380) of patients developed at least one postoperative complication. In the first analysis, which included all the patients, 24.7% of temporary stomas remained unclosed. In the second analysis for 335 patients with a primary stoma, 23.3% were left with unclosed stomas. After the COX regression analysis, both major POCs and minor POCs were found to be independent risk factors for the permanent stoma, and there was an increasing tendency toward the risk of permanent stoma with the increase in POC severity.
Conclusion
POCs are independent predictors of permanent stoma after rectal cancer surgery. Even minor POCs may affect the outcome, while there is a clear direct relationship between POC severity and permanent stoma rates.
