To evaluate whether surgical resection confers survival advantages in selected patients with resectable locally recurrent rectal cancer, data on 430 patients who underwent R0 resection for primary rectal cancer were prospectively collected over a 14-year period. Resection of recurrent disease was considered R0 when all cancer tissue was resected with microscopically tumor-free surgical margins. Microscopic evidence of disease at resection margins was considered an R1 resection. ⋯ Median survival rate was not reached at the 146-month follow-up in patients with R0 resection. Median survival rate was 16.6 months in patients with R1 resection. In conclusion, uninvolved microscopic margins produce long-term survivors after surgical resection for locally recurrent rectal cancer.

Following stoma construction, parastomal hernia is the most frequent complication. Many surgical techniques have been postulated for these patients, and prosthetic surgery represents the first-choice treatment. We report our personal experience with 8 cases of parastomal hernia in patients submitted to abdominal perineal resection according to Miles, for carcinoma of the lower rectum. ⋯ The mesh was placed in suprafascial position, after suturing the fascial tear. One case of wound infection occurred and, to date, none of the patients have presented with recurrence after a 3-year follow-up. In conclusion, the use of polypropylene mesh for parastomal hernia repair represents a safe and successful technique.
