Because Crohn's disease of the small bowel is often diffuse, strictureplasty has been advocated as an alternative or adjunct to resection(s) of strictured segments. We reviewed 116 patients with obstructive Crohn's disease undergoing 452 primary strictureplasties (Heineke-Mikulicz, 405; Finney, 47). The median age was 34 years (range, 13-72 years); the male-to-female ratio 1.4:1; and the median follow-up was three years (range, six months to seven years). Seventy-six patients (66 percent) had at least one previous small bowel resection. Perforative disease was present in 18 patients (15 percent), and synchronous resections were performed in 71 patients (61 percent). The median number of strictureplasties was three (range, 1-15). There was no mortality. Septic complications (intra-abdominal abscess/fistula) occurred in seven patients (6 percent), and reoperation for sepsis was needed in two patients. Relief of obstructive symptoms was achieved in 99 percent of the patients. After surgery, the median weight gain was 4 kg, and two-thirds of the patients were weaned off steroids. Symptomatic recurrence occurred in 28 patients (24 percent), and 17 patients (15 percent) needed reoperation. Rates of restricture and new stricture/perforative disease were 2.8 percent and 24 percent, respectively.
