Local flap reconstruction of the perineum and anal canal is an excellent method of managing large perineal defects. Benefits of V-Y flaps compared with other methods such as vertical rectus abdominis myocutaneous include reduced donor-site morbidity and increased ease of harvest and inset. This is a case report of bilateral gluteal V-Y fasciocutaneous reconstruction of perineal defect, in a post-irradiated anorectal carcinoma patient, with excellent outcome.

A 56-year-old female with a past history of treated carcinoma breast was evaluated for bleeding per rectum. Sigmoidoscopy showed an ulceroproliferative growth just above the anal verge, and biopsy showed moderately differentiated adenocarcinoma. Serum carcinoembryonic antigen was 6.3 ng/ml. Contrast-enhanced computed tomography abdomen showed locally advanced growth in the rectum, close to the anal verge, with enlarged perirectal lymphnodes. Metastatic work-up was negative. The patient received neoadjuvant chemoradiotherapy. Post-neoadjuvant therapy magnetic resonance imaging showed anorectal thickening infiltrating the mesorectal fascia and levator ani. In addition, there was a perianal fistula, coursing through the right levator ani and opening into the gluteal cleft. There was a focal loss of a fat plane with the posterior vaginal wall. On examination, her performance status was PS-1. Abdominal examination was normal. The growth was palpable through the posterior vaginal wall, and the vaginal mucosa appeared free. On rectal examination, the growth was felt at 1 cm from the anal verge, with the external fistula opening at 9'o clock position.
Extra levator abdomino perineal excision with bilateral gluteal V-Y advancement fasciocutaneous flap reconstruction was done. Initially, rectosigmoid mobilisation was done through lower midline laparotomy, and a proximal bowel cut was made. The end stoma was fashioned in the left iliac region and the omentum was packed into the pelvis. In prone jack-knife position, perineal dissection was done, removing the bilateral levator muscles at origins, coccyx and adherent posterior vaginal wall. The vaginal defect was closed primarily. The perineal defect was reconstructed with a bilateral gluteal V-Y advancement fasciocutaneous flap. The medial 2-cm wide portions of the flaps were de-epithelialised and filled into the pelvic cavity. Post-operatively, the patient convalesced well [Figure 1], [Figure 2], [Figure 3], [Figure 4], [Figure 5], [Figure 6], [Figure 7].

| Discussion|| |
Extensive perineal defect following abdominoperineal resection (APR) is traditionally managed via a primary closure strategy. Reported complications related to primary perineal closure after APR include seroma, abscess formation and wound dehiscence; these complications are prevalent in 30%–66% of patients. Local flap reconstruction of the perineum and anal canal is an excellent method of managing large perineal defects. Although several techniques such as musculocutaneous flaps and free tissue transfers have been described, they are much complicated. The benefits of V-Y flaps compared with other methods such as vertical rectus abdominis myocutaneous include reduced donor-site morbidity and increased ease of harvest and inset. In small institutional series, V-Y flap closures were associated with higher primary healing rates, even in the setting of neoadjuvant radiotherapy. Arnold et al. reported outcomes from V-Y fasciocutaneous flaps based on the inferior gluteal artery perforators to reconstruct the perineal defect after APR in 18 patients. The median hospital length of stay was 12 days, and the reported rate of minor wound complications (including abscesses and drainage) occurred at 39% and major complications (including flap dehiscence) occurred in 11% of patients. The perineal complication rate (including abscess, dehiscence and delayed healing) is 17%. Additional advantages of the V-Y flaps include the additional bulk created by the bilateral flaps; symmetric scarring; ability to recreate the vertical gluteal cleft and also, not associated with weakness or problems with balance, sitting or walking. This is a report of one such bilateral gluteal V-Y fasciocutaneous reconstruction of perineal defect, after extensive perineal resection, in a post-irradiated patient, with very good outcome.
