Summary
Internal rectal intussusception involves rectal infolding during defecation, causing pressure and pain. Defecography is key for diagnosis, with conservative management recommended for most patients.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Diagnostic Imaging
Background:
- Internal intussusception of the rectum is characterized by rectal infolding during defecation.
- Common symptoms include rectal pressure, pain, constipation, and straining.
Purpose of the Study:
- To describe the presentation, diagnosis, and management of internal rectal intussusception.
Main Methods:
- Defecography (videofluoroscopy during defecation) is the primary diagnostic tool.
- Findings are graded from I-IV based on rectal mobility, infolding, and sphincter relaxation.
Main Results:
- Defecography allows for grading of internal rectal intussusception severity.
- The underlying cause remains unknown, impacting optimal therapeutic strategies.
Conclusions:
- Internal rectal intussusception diagnosis relies on defecography.
- Conservative management is advised for most cases, with optimal therapy still undetermined.
