Insights
A new surgical technique combining endorectal mucosectomy and double-stapled anastomosis offers a safe and effective option for pediatric restorative proctocolectomy, showing promising functional outcomes.
Area of Science:
- Pediatric surgery
- Gastrointestinal surgery
- Surgical innovation
Background:
- Restorative proctocolectomy in children typically involves hand-sewn ileo-anal anastomosis, which can be technically challenging.
- A novel technique was developed to address difficulties associated with hand-sewn anastomoses.
Purpose of the Study:
- To evaluate a new surgical technique for pediatric restorative proctocolectomy.
- To assess the feasibility and early outcomes of combining endorectal mucosectomy with a double-stapled ileo-anal anastomosis.
Main Methods:
- The technique involves creating an ileal J-pouch and performing an endorectal mucosectomy.
- A double-stapled anastomosis is achieved by eversion of the rectal mucosal tube and transanal stapler deployment.
- A loop ileostomy is constructed post-operatively.
Main Results:
- Thirteen pediatric patients (mean age 12.3 years) underwent the procedure without major complications.
- Average operative time was 280+/-70 minutes.
- At 9 months follow-up, mean 24-hour stool frequency was 6.8, with 1.0 at night.
Conclusions:
- Endorectal mucosectomy with double-stapled anastomosis is a novel approach for pediatric restorative proctocolectomy.
- Early experience indicates a low complication rate and excellent functional results with this technique.
Background:
In children, restorative proctocolectomy is usually accomplished by a rectal mucosectomy followed by a hand-sewn ileo-anal anastomosis+/-ileal pouch. In certain patients, a hand-sewn anastomosis can be technically difficult. This led us to develop a new technique that combines endorectal mucosectomy with a double-stapled ileo-anal anastomosis.
Methods:
After colectomy, an ileal J-pouch is constructed. The head of the circular stapler is placed in the apex of the pouch and secured. An endorectal mucosectomy is completed from the abdomen to approximately 1.5 cm above the dentate line. The rectal mucosal/submucosal tube is everted onto the perineum. A transverse stapler is positioned 1.5 cm above the dentate line on the perineum and fired. The circular stapler is inserted transanally and the trocar advanced through the transverse staple line until the head and anvil are mated and then fired. A loop ileostomy is constructed.
Results:
Thirteen patients, with a mean age of 12.3 years, have undergone endorectal mucosectomy with a double-stapled anastomosis without major complication. The operative time averaged 280+/-70 minutes. The mean 24-hour stool frequency, with 9 months' follow-up, was 6.8+/-3.2, of which 1+/-0.7 were at night.
Conclusions:
The combination of endorectal mucosectomy with a double-stapled anastomosis is a new approach for patients requiring restorative proctocolectomy. In our early experience, this technique was completed with a low complication rate and excellent functional results.
