Summary
Rectal invagination surgery may not fully restore rectal emptying, potentially due to autonomic denervation. Defecography shows persistent difficulties post-operation.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Diagnostic Imaging
Background:
- Rectal invagination is a recognized cause of obstructed defecation.
- Defecography is a key imaging modality for evaluating rectal function.
Purpose of the Study:
- To review defecography findings in patients with rectal invagination.
- To assess the impact of rectopexy on anorectal angles, pelvic floor function, and rectal emptying.
Main Methods:
- Retrospective review of defecography in 15 patients diagnosed with rectal invagination.
- Comparison of pre- and post-operative imaging in 8 patients.
- Analysis of anorectal angles, pelvic floor elevation, rectocele presence, and rectal emptying capacity.
Main Results:
- Most patients had intra-rectal or intra-anal invagination.
- Post-rectopexy, anorectal angles and pelvic floor elevation showed no significant changes.
- Rectal emptying capacity was reduced in all but one patient post-operatively, suggesting possible autonomic denervation.
Conclusions:
- Rectopexy for rectal invagination may not resolve defecation difficulties.
- Impaired rectal emptying post-surgery warrants further investigation into potential autonomic denervation.
