The low mucosa and the submucosal muscle of the rectum were circumferentially resected,using the stapler, so as to make the rectocele of the rectal anterior wall disappeared and make the rectal anterior wall and the mucosa slightly tensed. Results showed that normal defecation was resumed with no notable complications, and that the general effective rate was 91.6%. It is concluded that the therapeutic efficacy of PPH in the treatment of the constipation caused by rectocele and relaxed rectal mucosa is good with less surgical trauma and complication.
