Abstract:

BACKGROUND: Effective artificial anal sphincter reconstruction can improve the survival and quality of life of patients with anal incontinence.
OBJECTIVE: To evaluate the effect of autologous muscle transplantation on the reconstruction of artificial anal sphincter.
METHODS: The anatomical basis of autologous gluteus maximus and gracilis transplantation for artificial anal sphincter reconstruction was analyzed, and the patients received artificial anal sphincter reconstruction with autologous gluteus maximus and gracilis transplantation were follow-up observed. The effect of autologous gluteus maximus and gracilis transplantation on artificial anal sphincter reconstruction was identified through evaluating the recovery of bowel control of artificial anus and the incidence of complications.
RESULTS AND CONCLUSION: Both gluteus maximus and gracilis had the rich blood supply, and the arteries used to provide nutrition to the muscles had the corresponding veins and nerves accompanied. The patients received artificial anal sphincter reconstruction with autologous gluteus maximus and gracilis transplantation were follow-up observed and showed that the patients were mostly suffered colorectal cancer or anal cancer. After artificial anal sphincter reconstruction with autologous muscle transplantation, all the patients obtained good bowel control and defecation function with less anal stenosis, perianal infection or other complications, and no rejection was observed.
