Abstract: Objective To study the prevention and treatment of complications of colostomy with carcinoma of large intestine.Methods 82 colostomies with carcinoma of large intestine were reviewed.The incidence and method of treatment of peristomal dermatitis,stomal necrosis,stomal hemorrhage,disassociation of skin and mucosa,infection,stomal retraction,stomal stenosis and prolapse of the stomal were analyzed.Results All stomal complications occurred in 24 patients(29.27%).The occurrence rates of partial necrosis,retraction and stenosis were higher in emergency operations than those in seleclive operations(χ²=8.2,P＜0.05).The complications of colostomy were mainly due to technical factors and could be prevented.The GOL(quality of life)of the patients with colostomy complications was depressed(t=3.325,P＜0.05).There were no death patients with the complications of colostomy in this group.Conclusions Sufficient preoperative intestinal preparation,rational chosing operative modality,location of colostomy and operative instruments properly selected,careful operative performation and postoperative treatment are the key points to avoid the complication and improve the life quality of the patients with carcinoma of large intestine.
