About This Patent
Patent No. 557908 protects the BEST (Bio-Enhanced Sphincter-saving Treatment) Device — a novel surgical instrument invented by Dr. Ashwin Porwal specifically designed to treat complex and recurrent anal fistulas while completely preserving anal sphincter function.
Complex anal fistulas — including intersphincteric, transsphincteric, suprasphincteric, and horseshoe types — pose a significant surgical challenge because conventional treatments like lay-open fistulotomy carry an unacceptable risk of faecal incontinence by cutting through the sphincter muscles.
The BEST Device enables the surgeon to deliver targeted energy precisely within the fistula tract, ablating the tract lining and promoting fibrotic closure from within — without any division of sphincter muscle. This approach, combined with Dr. Porwal's DLPL (Distal Laser Proximal Ligation) technique, has achieved high primary healing rates in complex fistulas with zero reported cases of faecal incontinence.
The device has been used in hundreds of complex fistula cases at Healing Hands Clinic including cases involving bilateral supralevator abscesses and anoscrotal fistulas.
