Summary
Ileal graft rectal mucosal replacement preserves fecal continence for patients with ulcerative colitis or familial polyposis, avoiding risks of disease recurrence or cancer.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Surgical Innovation
Background:
- Rectal preservation in ulcerative colitis (UC) and familial polyposis (FP) risks disease recurrence or malignancy.
- Current treatments may compromise fecal continence.
Purpose of the Study:
- To evaluate the efficacy of rectal mucosal replacement with an ileal graft.
- To assess the preservation of fecal continence and oncologic safety.
Main Methods:
- Total colectomy with rectal mucosal-submucosal removal and ileal graft reconstruction.
- Construction of a rectal reservoir for intestinal continuity restoration.
- Follow-up of 29 patients (12 FP, 17 UC) for up to 7 years.
Main Results:
- 23 out of 25 patients with restored intestinal continuity achieved satisfactory results.
- Fecal continence was preserved in all evaluated patients.
- Patients averaged six stools per 24-hour period.
Conclusions:
- Ileal graft rectal mucosal replacement is a viable technique for UC and FP.
- This procedure effectively conserves fecal continence.
- It mitigates the risks associated with recurrent disease or malignant transformation.
