The evidence for the value of noxytiolin (Noxyflex) in peritonitis is contradictory. In a controlled trial of the effect of noxytiolin in pertonitis in rabbits we have found a significant increase in mortality in the trial group compared with a control group, but no significant difference when a dose equivalent to the recommended human dose is used. The postoperative course is adversely affected in the animals receiving noxytiolin.
A comparison is made of the immediate and long term mortality of colectomy and ileostomy between 73 patients who had Crohn's colitis and 442 who had ulcerative colitis. The immediate mortality in Crohn's disease is 4%. In ulcerative colitis it is 10%, chiefly because of the higher proportion of emergency operations. The late mortality in both groups is 10%, chiefly as a result of recurrence of Crohn's disease or the sequellae of colonic malignancy present at the time of colectomy for ulcerative colitis. A further comparison is made between the postoperative course of the 64 surviving patients with Crohn's disease and a comparable sample of 65 patients who had an ileostomy for ulcerative colitis in the same era. There was a similar incidence of postoperative septic complications in the two groups (35%). The readmission rate was twice as high in the Crohn's disease patients. Ileostomy reconstruction for mechanical complication was needed in 21 patients with Crohn's disease compared with 6 with ulcerative colitis. Further ileal resection was required for recurrent disease on another 25 occasions in the patients with Crohn's disease but never in those with ulcerative colitis. Long therm review graded the clinical status as excellent or good in 70% of those with Crohn's disease compared with 95% with ulcerative colitis.

Nineteen New Zealand White Rabbits were inoculated intramurally into the intestine with a 100- or 0.2-mu filtrate of homogenate of fresh ileum or colon from each of 6 patients with histologically confirmed Crohn's disease and compared with 22 animals injected with homogenates of normal ileum or colon from each of 5 patients; 4 sham controls were also included. The animals receiving Crohn's homogenates put on less weight than the controls; mucosal ulceration, ileal thickening, and abscess formation were seen in 8 animals and granulomatous changes evolved in 9. No significant macroscopic abnormalities or granulomatous changes were present in any of the 22 control inoculated rabbits. Successful first passage was achieved from 6 of 11 rabbits. The results of these experiments therefore confirm and extend those of our earlier reports and demonstrate that the transmissible agent or agents responsible must approximate to the size of a virus or be capable of being deformed to pass through a 0.2-mu filter.
This paper reports the indications for, and results of, excision of the large intestine with ileostomy in 73 patients with Crohn's colitis who have been followed for a mean of nine years since resection. Sixty-four of them are still alive and all but two of the survivors are now in good health.However, 23 (33%) have developed recurrent Crohn's disease since resection. This is higher than that reported in many other series and may be due to differences in the length of follow up, the site and extent of colonic disease, the age of the patient at the time of excision with ileostomy, and differences in the pathological interpretation of the diagnosis of Crohn's disease. The high recurrence rate in this series lends caution to the view that the prognosis after excisional surgery and ileostomy for Crohn's colitis is as good as after the same operation for ulcerative colitis and should influence the decision when the alternative of medical or surgical management are being considered for patients with Crohn's colitis.
