PURPOSE: Enterocele is defined as a herniation of the peritoneal sac betwee
n the vagina and the rectum. This hernial sac contains either sigmoid colon
or small bowel. It is well known that enteroceles are associated with symp
toms of pelvic discomfort. It is unclear whether enteroceles contribute to
evacuation difficulties. Controversies also exist regarding their treatment
of choice. The aim of the present prospective study was to evaluate the im
pact of obliteration of the pelvic inlet on evacuation difficulties and on
symptoms of pelvic discomfort. METHODS: From October 1994 to August 1996 20
females (median age, 53; range, 41-73 years) with symptomatic enterocele d
iagnosed on evacuation proctography underwent obliteration of the pelvic in
let with a nonabsorbable Mersilene(R) mesh. All patients presented with pel
vic discomfort, characterized by feelings of prolapse (n = 20), pelvic pres
sure (n = 16), lower abdominal pain (n = 13), and false urge to defecate (n
= 15). Symptoms of obstructed defecation were noted in 15 patients. Six mo
nths after repair, evacuation proctography with opacification of the small
bowel and the vagina was repeated. RESULTS: The median duration of follow-u
p was 25 (range, 10-34) months. A persistent or recurrent enterocele was ob
served in none of the patients. All symptoms of pelvic discomfort disappear
ed except feelings of a false urge to defecate, which persisted in 27 perce
nt of cases. Symptoms of obstructed defecation persisted in all patients wi
th evacuation difficulties. CONCLUSIONS: In patients with pelvic discomfort
enterocele should be considered as a possible causative factor. It is unli
kely that this abnormality contributes to the problem of obstructed defecat
ion. In patients with a symptomatic enterocele, obliteration of the pelvic
inlet with a Mersilene(R) mesh is an adequate treatment.
