Introduction:
Several procedures have been described for the excision of perirectal tumours. Among them are the Kraske and York Mason operations, and the transanal approach, which may cause anal incontinence and rectal bleeding. A novel technique, i.e. the perianal intersphincteric excision (PIE), is reported here with the aim of minimising such postoperative complications, as it avoids both stretching the sphincters and endorectal wounding.
Case Report:
The procedure has been carried out successfully in two patients: a woman with a low-grade rectal leiomyosarcoma and a man with a perirectal schwannoma. No postoperative complications were observed, and no recurrence was detected after 36 and 8 months respectively.
Conclusion:
In conclusion, PIE seems to be a safe and effective procedure for the management of perirectal masses.
