Objective: To identify the risk factors associated with non-closure of defunctioning stoma in patients with rectal cancer.
Material And Methods: A retrospective analysis included patients who underwent surgical treatment at the Ryzhikh National Medical Research Centre of Coloproctology for the period from March 2017 to August 2019. Inclusion criterion was anterior or low anterior resection followed by anastomosis and preventive stoma. Univariate and multivariate analysis enrolled 28 factors for identifying the risk factors of non-closure of defunctioning stoma.
Results: There were 246 patients with rectal cancer. Intraoperative fluorescence angiography was applied in 145 cases to assess blood supply within the anastomosis and reduce the risk of anastomotic leakage. According to multivariate analysis, only two factors had significant influence on non-closure of preventive stoma - any grade of anastomotic leakage (OR 6.5; 95% CI 2.2-18.8, =0.001) and rectal cancer stage IV (OR 7.2; 95% CI 1.9-27.6, =0.004).
Conclusion: According to our data, permanent stoma is observed in 15% of patients.

Purpose: Defunctioning ileostomies are often performed during rectal cancer surgery. However, stomas are sometimes associated with complications, while 20-30% of them are never reversed. Additionally, ileostomy closure can have associated morbidity, with rates as high as 45%, with the respective literature evidence being scarce and conflicting.

Background: Our clinical experience led us to raise questions about the validity of the reported risk factors and patient characteristics associated with permanent stomas after sphincter-preserving resection for rectal cancer.
Objective: The present retrospective study aimed to identify and compare our center's incidence and risk factors for a permanent ostomy after low anterior resection (LAR) with a diverting stoma for locally advanced mid and low rectal cancer with those in published reports.
Patients: A total of 239 patients underwent a sphincter-preserving procedure (LAR) for rectal cancer between 2000 and 2018, and 236 of them (age range 33-83 years, 100 males (42%)) were included in the analysis.
Objective: To identify the risk factors associated with non-closure of defunctioning stoma in patients with rectal cancer.
Material And Methods: A retrospective analysis included patients who underwent surgical treatment at the Ryzhikh National Medical Research Centre of Coloproctology for the period from March 2017 to August 2019. Inclusion criterion was anterior or low anterior resection followed by anastomosis and preventive stoma.
Aim: Delay to closure of ileostomy following anterior resection for rectal cancer may impair postoperative bowel function and quality of life. We analysed time to ileostomy closure across the UK and investigated factors delaying closure.
Methods: For the retrospective cohort we assessed time to closure and incidence of non-closure for patients who underwent anterior resection with defunctioning ileostomy during 2015.

Purpose: A substantial part (21-35%) of defunctioning stomas created during resection for colorectal cancer will never be reversed. Known risk factors for non-closure are age, peri- or postoperative complications, comorbidity, and tumor stage. However, studies performed to identify these risk factors mostly focus on rectal cancer and include both preoperative and postoperative factors.
