We recommend biological mesh reconstruction of the pelvic floor after extralevator abdominoperineal resection because this method can achieve a high healing rate with an acceptable risk of infection, a low hernia rate, and a shorter hospital stay without donor-site morbidity.

Salvage surgery of recurrent or persistent anal cancer following radiotherapy is often followed by perineal wound complications. We examined survival and perineal wound complications in anal cancer salvage surgery during a 10-year period with primary perineal reconstruction predominantly performed using vertical rectus abdominis myocutaneous (VRAM) flap. Between 1997 and 2006, 49 patients underwent anal cancer salvage surgery. Of these, 48 had primary reconstruction with VRAM. Overall survival was computed by the Kaplan-Meier method and mortality rate ratios (MRRs) by Cox regression. One patient (2%) died within 30 days postoperatively. Postoperative complications necessitated reoperation in eight (16%) patients. We found no major perineal wound infections. Major perineal wound breakdown occurred in the only patient in whom VRAM was not used. Five-year survival was 61% [95% confidence interval (CI) 43-75%]. Free resection margins (R0) were obtained in 78% of patients, with 5-year survival of 75% (95% CI 53-87%). Involved margins, microscopically only (R1) or macroscopically (R2), strongly predicted an adverse outcome [age-adjusted 2-year MRRs (95% CI) R1 vs. R0 = 4.1 (0.7-23.6), R2 vs. R0 = 10.9 (2.2-54.2)]. We conclude that anal cancer salvage surgery can yield long-time survival but obtaining free margins is critical. A low rate of perineal complications is achievable by primary perineal reconstruction using VRAM flap.

Combining the salvage operation with a VRAM flap facilitates primary healing after surgical treatment for persistent or locally recurrent anal cancer. A single-stage primary reconstructive procedure is feasible, with an acceptable complication rate and high level of patient satisfaction.

Knowledge about perforators and angiosomes has inspired new and innovative flap designs for reconstruction of defects throughout the body. The purpose of this article is to share our experience using color Doppler ultrasonography (CDU)-targeted perforator mapping and angiosome-based flap reconstruction throughout the body. The CDU was used to identify the largest and best-located perforator adjacent to the defect to target the reconstruction. The cutaneous or fasciocutaneous flaps were raised, mobilized, and designed according to the reconstructive needs as rotation, advancement, or turnover flaps. We performed 148 reconstructions in 130 patients. Eleven facial reconstructions, 118 reconstructions in the body, 7 in the upper limbs, and 12 in the lower limbs. The propeller flap was used in 135 of 148 (91%) cases followed by the turnover design in 10 (7%) and the V to Y flap in 3 (2%) cases. The flaps were raised on 1 perforator in 98 (67%), 2 perforators in 48 (33%), and 3 perforators in 2 (1%) flaps. The reconstructive goal was achieved in 143 of 148 reconstructions (97%). In 5 cases, surgical revision was needed. No flaps were totally lost indicating a patent pedicle in all cases. We had 10 (7%) cases of major complications and 22 (15%) minor complications. The CDU-targeted perforator mapping and angiosome-based flap reconstruction are simple to perform, and we recommended its use for freestyle perforator flap reconstruction. All perforators selected by CDU was identified during surgery and used for reconstruction. The safe boundaries of angiosomes remain to be established.

Gracilis transposition is a viable option as a treatment for complex perianal Crohn's disease. Efficacy was maintained in nearly 90% of patients in the medium to long term.
