“…Only four patients still have successfully functioning ileorectal anastomoses and four patients have died from the effects of the disease. Acute toxic dilatation of the colon has been recognized as a complication of ulcerative colitis for many years (Lumb, Protheroe, and Ramsay, 1955;Roth, Valdes-Dapena, Stein, and Bockus, 1959; Morson and Dawson, 1972) but its occurrence in Crohn's colitis has not been described until recently. We know of only 11 cases of acute toxic dilatation of the colon in Crohn's colitis with reasonably full clinical and pathological details (Schachter, Goldstein, and Kirsner, 1967;McGovern and Goulston, 1968;Javett and Brooke, 1970;Leoutsakos and Pedridis, 1970;Papp and Pollard, 1970;Clark, 1972), and of 18 others without full descriptions (Farmer, Hawk, and Turnbull, 1968;Fielding and Truelove, 1972;Brooke, 1972).…”
