Rectal prolapse
External prolapse, dominant prolapse
1.Grading standard
Ⅰ degree: when defecating or increasing abdominal pressure, the rectal mucosa prolapses out of the anus.
Ⅱ degree: when defecating or increasing abdominal pressure, the whole rectum prolapses out of the anus.
Degree III: When defecating or increasing abdominal pressure, the whole layer of the anal canal and rectum or part of the sigmoid colon prolapses out of the anus. The length of prolapse should be indicated when diagnosing various kinds of prolapse.
2.In rectal prolapse, the judgment of anal sphincter function
(1)Good function of anal sphincter: Self-controlled defecation, strong sphincter contraction and good anal closure.
(2) Poor function of anal sphincter: usually mucus overflows outside the anus, sometimes loose stool cannot be controlled, sphincter contraction is weak, and the anal opening is not closed tightly.
(3) No anal sphincter function: usually gas and dilute stool can not be controlled, sometimes dry stool can not be controlled, sphincter muscle atrophy, no contraction of the anus, the anus can not be closed.
3, rectal prolapse efficacy standards
(1) healed: Ⅰ degree prolapse symptoms disappear, rectal mucosa no longer prolapse out of the anus; Ⅱ, Ⅲ degree prolapse, rectal whole layer no longer prolapse out of the anus.
(2) Improved: symptoms basically disappear and prolapse is significantly reduced.
(3) invalid: no significant changes after treatment.
4, rectal prolapse postoperative reaction observation criteria
(1)Pain, fever and urination disorder are the same as the postoperative criteria for hemorrhoids.
(2) Cramping or persisting for several days.
5.Standards for judging the function of anal sphincter after rectal prolapse surgery
(1)Improvement of anal sphincter function: those without anal sphincter function before surgery become poor or good sphincter function, and those with poor sphincter function before surgery become good.
(2) Poor anal sphincter function: postoperative anal sphincter function is reduced compared with that before surgery, and those with good anal sphincter function before surgery become poor or no sphincter function.
6.Long-term efficacy criteria
No recurrence after 2 to 3 years of postoperative follow-up is considered as long-term cure.
