TRAF is a safe technique for managing complicated anorectal and rectovaginal fistulas, including patients with Crohn's disease. Long-term follow-up is essential to accurately report recurrence rates.

Patients with a history of colonic diverticular bleed are prone to recur shortly thereafter. Certain risk factors including increased age, documented diverticulitis, history of peripheral vascular disease, and chronic renal failure may predispose to recurrence.

Strictureplasty is a safe and effective procedure for Crohn's disease in selected patients. Reoperative rates are comparable with resective surgery, and most recurrences occur at new sites.

The occurrence of small-bowel cancer in Crohn's disease (CD) is a rare event. The risk seems to be greatest in patients with long-standing disease. Strictureplasty has proved to be a valuable alternative in the management of Crohn's strictures of the small-bowel. Critics and proponents of strictureplasty for selected patients with small-bowel Crohn's disease have voiced their concerns about cancer risk in the strictured or strictureplasty site. To date, there has been no clear or detailed report of such an occurrence. The authors report the first case of small-bowel adenocarcinoma arising at the site of a previous strictureplasty. In this patient, biopsies of the strictures at the original operation confirmed CD and excluded both cancer and dysplasia. Malignancy occurred seven years later at a strictureplasty site. The main clinical sign associated with the adenocarcinoma was severe, persistent anemia. The authors conclude that the risk of adenocarcinoma developing at the site of a previous strictureplasty for CD, although small, is real.

Successful treatment of fistula from a pelvic pouch can be achieved in more than 60 percent of patients. However, multiple procedures may be needed for a successful outcome. Ultimately, 32 percent had their pouches excised.

Squamous colorectal cancer can be detected in any part of the colon, generally presents at a later stage, and is associated with a poor prognosis. Surgery is the mainstay of treatment. Various adjuvant chemoradiation treatments appear not to influence the outcome. Further cases need to be analyzed in order to find more effective treatment regimens.

In patients where abdominal repair of rectal prolapse is judged to be unwise, a Delorme procedure offers short-term control of the prolapse with low risk of complications and with reasonable function. In addition, patients that recur after a Delorme procedure can undergo another similar transanal procedure without compromising the vascular supply of the rectum.
