[Reconstruction of large tissue loss of the anus and perineum with bilateral inferior gluteal and right gracilis myocutaneous flaps].

The authors present a case of locally advanced anal squamous cell carcinoma which, due to infiltration of deep structures, caused anal incontinence, serious pain, exulceration, and bleeding. Neoadjuvant radiotherapy made the tumour operable and abdominoperineal extirpation was performed. The large tissue loss of the anal and perineal region was covered by bilateral gluteus maximus myocutaneous flaps, and the loss of the pelvic musculature and the remaining pelvic skin loss were replaced by a right gracilis myocutaneous flap. The patient was discharged on the 36th postoperative day. There was no flap necrosis noted and an incomplete lesion of the proximal urethra healed after direct suturing. The patient was allowed to lye on the flap in the second postoperative month and sitting on the third month. Unfortunately, an inoperable infiltrative lymph node metastasis occurred in the right inguinal region after six months, and the patient died 10 months after the surgery. We believe that in cases of large, ulcerating anal tumours, when direct closure would be impossible due to massive tissue loss after resection, quality of life can be significantly improved by resection and closure with myocutaneous flaps.
