Summary
S-plasty effectively treated various anal conditions in ten patients, yielding satisfactory anatomic and functional outcomes. This surgical technique is recommended for reconstructing extensive anal canal defects with full-thickness skin flaps.
Area of Science:
- Colorectal Surgery
- Dermatologic Surgery
- Surgical Oncology
Background:
- Anal canal reconstruction presents challenges due to limited tissue and functional demands.
- Various conditions like giant condyloma acuminata and verrucous carcinoma require extensive tissue removal, necessitating complex reconstructive methods.
Purpose of the Study:
- To evaluate the efficacy and safety of S-plasty for reconstructing the anal canal after extensive tissue excision.
- To assess both the anatomical and functional outcomes of S-plasty in a cohort of patients with diverse anal pathologies.
Main Methods:
- A retrospective review of ten patients who underwent S-plasty between 1979 and 1990.
- S-plasty involved the use of bilateral rotating full-thickness skin flaps for reconstruction of the anal canal.
Main Results:
- All ten patients achieved satisfactory anatomical and functional results following S-plasty.
- No serious complications were reported in the study cohort.
- Indications included giant condyloma acuminata (6 patients), Bowen's disease, verrucous carcinoma, stricture, and ectropion.
Conclusions:
- S-plasty is a preferred and effective method for reconstructing extensive circular denuded anal canals.
- The technique requires careful flap design with adequate blood supply and meticulous hemostasis for optimal results.
