S. Bremmer et al., PERITONEOCELE AND ENTEROCELE - FORMATION AND TRANSFORMATION DURING RECTAL EVACUATION AS STUDIED BY MEANS OF DEFAECO-PERITONEOGRAPHY, Acta radiologica, 39(2), 1998, pp. 167-175
Purpose. To study, by means of defaeco-peritoneography, the formation
and transformation of the peritoneocele, with and without an enterocel
e, during rectal evacuation. Material and Methods. Forty-six patients
with a peritoneocele at defaeco-peritoneography were selected for the
study, and examined at three different stages: 1) at the start with a
contrast-filled rectum; 2) at maximum straining; and 3) at rest after
rectal evacuation. Results: Fourteen patients had a peritoneocele at t
he start. These peritoneoceles were largest at maximum straining and w
ere all still present at rest after rectal evacuation. In 32 patients
defaeco-peritoneography was regarded as normal at the start. At maximu
m straining these patients developed a peritoneocele and 20 of these w
ere still present after rectal evacuation. No enterocele was seen at t
he start. At maximum straining 21 patients developed an enterocele and
15 of these were still present after rectal evacuation. Liquid in var
ying amounts was found in the peritoneoceles. Conclusion: The present
study demonstrated that peritoneoceles were present at different stage
s of the defaeco-peritoneographic investigations. Peritoneoceles were
most frequent and largest at maximum straining. An enterocele was pres
ent in half of the peritoneoceles at maximum straining, but never at t
he start. Liquid was often present in the peritoneoceles.
