[Long-term results of ileo-rectal anastomosis in familial polyposis]
Insights
Familial adenomatous polyposis (FAP) patients undergoing subtotal colectomy with ileorectoanastomosis had high mortality and rectal stump cancer rates. Colectomy with ileoanal anastomosis and an ileal reservoir is recommended for better outcomes.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Genetics
Context:
- Familial adenomatous polyposis (FAP) is an inherited condition predisposing individuals to colorectal cancer.
- A 36-year retrospective study analyzed 93 FAP patients treated at Charles University Prague.
- Follow-up data from 91 patients informed surgical outcome analysis.
Purpose:
- To evaluate the long-term outcomes of surgical management for familial adenomatous polyposis (FAP).
- To assess the incidence of mortality and secondary malignancies after subtotal colectomy with ileorectoanastomosis.
- To determine the optimal surgical approach for FAP patients.
Summary:
- Subtotal colectomy with ileorectoanastomosis in 55 FAP patients resulted in a 38.5% mortality rate.
- Malignant tumors were detected in the rectal stump of 16.4% of patients within 16 years post-operation.
- Colectomy with ileoanal anastomosis and an ileal reservoir is proposed as a superior alternative.
Impact:
- Findings highlight significant risks associated with ileorectoanastomosis in FAP management.
- The study advocates for a shift towards more conservative ileoanal procedures with reservoirs.
- This research informs surgical decision-making and improves long-term FAP patient care and survival rates.
Abstract:
The authors present their experience with 93 patients operated at the First Surgical Clinic of the General Faculty Hospital and First Medical Faculty, Charles University Prague on account of familial adenomatous polyposis (FAP) assembled during 36 year starting in 1962. They analyze 91 patients followed up in collaboration with the First Medical Clinic of the General Faculty Hospital and First Medical Clinic Charles University Prague. Seventy-two of the patients were operated and in 55 of them an ileorectoanastomosis was made following subtotal colectomy. Two important findings were made. From the group of 91 patients incl. primary patients who suffered already from advanced malignant disease of the large bowel a total of 38.5% died. In the rectal stump after ileorectoanastomosis on average within 16 years after operation in 16.4% of the patients a malignant tumour was found. This leads to the belief that patients should be recommended colectomy with ileoanoanastomosis with an ileal reservoir. This operation was performed during the last five years in nine patients with this condition, using a one-stage or two-stage procedure with temporary ileostomy.
