Can rectum cancer protect anus

summary

Listen to the next door said, his uncle had rectal cancer earlier, plan to do anal surgery. His uncle asked the doctor, and the doctor said yes. But to do so, we must have certain conditions and principles. Let's talk about whether rectal cancer can protect anus and his principles.

Can rectum cancer protect anus

First, to ensure the radical cure of the tumor. Sphincter preserving surgery can not affect the long-term survival rate and increase the local recurrence rate. In order to improve the urination and sexual function of patients and improve the quality of life after anus preserving surgery, we should pay special attention to preserving pelvic autonomic nerve. If there is no residual cancer in the distal end of the bowel, a certain length of normal bowel above and below the primary tumor should be removed to ensure that the pathological examination of the distal cutting edge is negative.

Second, the function of anal defecation and control was good, and the quality of life was improved. It is necessary to have sound sphincter function and complete sensory reflex function, otherwise even if the anus is preserved, the purpose of improving the quality of life will be lost. After anus preserving radical resection for low rectal cancer, nearly 30% ~ 60% of the patients have defecation dysfunction in varying degrees. The closer the anastomotic stoma is to the anal margin, the higher the incidence and the more serious the degree. The symptoms are diarrhea, frequent defecation, fecal incontinence and other discomfort. These symptoms are related to the "new rectal capacity" function. In order to improve the defecation function after ultra-low rectal anastomosis, it is necessary to add colonic pouch or colonoplasty at the same time, but the pouch has advantages in the short term, but the long-term effect is not obvious.

Thirdly, we should strictly grasp the individualized principle of sphincter preserving surgery and choose different ways of sphincter preserving surgery. Dixon operation is the first choice if the residual rectum is larger than 2cm above levator ani muscle after rectectomy; if the residual rectum is smaller than 2cm, double stapler is used for trial anastomosis, with high success rate; Parks operation or modified bacon operation can be used if the residual rectum is too short and low anastomosis is difficult.

matters needing attention

Patients with rectal cancer should not only have rest after surgery. And in the aspect of diet, we should eat food that is beneficial to our body and can supplement energy. The family members should take care of the patients. If any symptoms occur after the operation, you should immediately seek medical examination.
