Summary
Stapled hemorrhoidectomy is a popular procedure, but anal dilator insertion can be difficult in some patients. This study introduces a modified circular anal dilator to ease insertion in individuals with challenging anatomy.
Area of Science:
- Colorectal Surgery
- Surgical Devices
- Anatomy
Background:
- Stapled hemorrhoidectomy is increasingly utilized globally for hemorrhoidal treatment.
- A common challenge during the procedure is the insertion of the circular anal dilator.
- Difficulties arise due to patient anatomy, specifically protuberant buttocks and narrow interischial distances.
Purpose of the Study:
- To describe a modified circular anal dilator.
- To facilitate easier insertion of the anal dilator in patients with specific anatomical variations.
Main Methods:
- Modification of a standard circular anal dilator.
- Clinical application of the modified device in patients with challenging anatomy.
Main Results:
- The modified device allows for easier introduction compared to the standard dilator.
- Improved patient tolerance and procedural efficiency are anticipated.
Conclusions:
- A modified circular anal dilator can overcome insertion difficulties in patients with protuberant buttocks and narrow interischial distances.
- This modification enhances the applicability of stapled hemorrhoidectomy in diverse patient populations.
