Abstract：Objective To explore the occurrence and related factors of ischemic necrosis of externally placed intestinal tube after modified Bacon operation,as well as the treatment measures.Methods The clinical data of 81 patients with low rectal cancer who were admitted to the First Affiliated Hospital of Zhengzhou University from November 2018 to March 2024 were retrospectively analyzed.Among the 81 patients,there were 8 cases with ischemic necrosis of externally placed intestinal tubes and 73 cases without ischemic necrosis of externally placed intestinal tubes.The occurrence and treatment measures of ischemic necrosis of externally placed intestinal tubes after modified Bacon operation were recorded,and the related factors affecting ischemic necrosis of externally placed intestinal tubes after modified Bacon operation were analyzed.Results Postoperative complications occurred in 20 cases(24.69％),including 8 cases of ischemic necrosis of externally placed intestinal tubes.Among the 8 cases of ischemic necrosis of externally placed intestinal tubes,3 cases had peritonitis after ischemic necrosis of externally placed intestinal tubes,and emergency sigmoidostomy was performed on them,and the other 5 cases had ischemic necrosis of externally placed intestinal tubes near the anal margin,without local and systemic symptoms,and conservative treatment was successful.Among the 20 case with postoperative complications,12 cases had anastomotic stenosis and underwent treatment of anal dilation.There were no cases of incision infection,anastomotic leakage and death within 30 days after operation.The patients'age,body mass index(BMI),sphincter tension status and mesorectal tension status were correlated with ischemic necrosis of externally placed intestinal tubes(P＜0.05).Conclusion Related factors for ischemic necrosis of externally placed intestinal tubes after modified Bacon operation include age,BMI,sphincter tension status and mesorectal tension status.The selection of patients,sufficient preoperative anal dilation,injection of botulinum toxin and regular postoperative observation are effective measures to prevent ischemic necrosis of externally placed intestinal tubes.
