Post-Fistulotomy Care and Sexual Practice Modifications

Introduction to Post-Fistulotomy Complications

• The American Society of Colon and Rectal Surgeons recommends that receptive anal intercourse should be avoided indefinitely after fistulotomy for a low transsphincteric fistula, as the mechanical trauma from penetration will likely cause wound dehiscence, recurrent abscess formation, and progressive sphincter damage that could lead to permanent fecal incontinence 1

Understanding the Risks of Receptive Anal Intercourse

• Receptive anal intercourse poses a significant risk of disrupting the healing surgical site, causing wound dehiscence and converting a successfully treated fistula back into an open wound, with a substantial risk of introducing infection into the healing wound 3
• The risk of progressive sphincter damage from repeated trauma could necessitate additional surgeries, each carrying a significant incontinence risk 4, 5

Postoperative Care and Rehabilitation

• Complete cessation of receptive anal intercourse is required for at least 12 months post-fistulotomy to allow for complete wound healing and scar maturation, with a graduated approach to resumption of sexual activity mandatory 3
• Prophylactic topical calcium channel blockers should be maintained before and after any activity to reduce sphincter hypertonicity 3

Specialist Referrals and Ongoing Care

• Immediate referral to a colorectal surgeon with sphincter preservation expertise is recommended for anorectal manometry and endoanal ultrasound to objectively assess sphincter function 3
