In an unselected series of 207 consecutive patients with Crohn's disease diagnosed between 1958 and 1974, 170 underwent a resection of all the macroscopically involved bowel ('radically' resected). Two patients died during the first postoperative month. The crude recurrence rate for the surviving 168 patients was 49%. The cumulative recurrence rate, calculated by the actuarial method, was 53% at 15 years. Age, sex, length of preoperative disease history, localization of the lesions in the bowel, and primary surgical procedures performed had no influence on the recurrence rate. However, the histopathological appearance of the resection margins seemed to influence the prognosis, since the presence of ulcers and/or granulomas was correlated with a significantly increased recurrence rate.

During a 5-year period, all the children born in Malmö, Sweden, were examined for congenital dislocation of the hip (CDH) and for inguinal hernia. Girls with CDH had a hernia five times more frequently than other girls, and boys with CDH three times more frequently. The children with CDH sustained their hernia abnormally early in life. We suggest that relaxin, which stimulates collagenase, could alter the connective tissue and be of importance for the development of both CDH and the hernia.

Crohn's disease confined to the appendix is a rare entity, less than 50 cases having been reported. The present study reports on another 12 cases representing 6 per cent of all 194 patients operated upon for Crohn's disease in a total, unselected series. The indications for surgery were appendicitis in eight patients, appendiceal abscess in two, suspected pyosalpinx in one, and an ovarian cyst in one. The appendices were in all cases strikingly enlarged. Giant-cell granulomas, without microabscesses were detected in all but one patient. Two patients had early septic postoperative complications. Fistulization from the cecum did not occur. The median observation time after operation was 13.8 years. Since none of the patients had further manifestations of the disease, it is concluded that patients with Crohn's disease confined to the appendix have a favorable prognosis.

In an analysis of a consecutive series of 133 patients with a diagnosis of Crohn's disease established preoperatively and in which early surgical intervention was the prevailing policy, the median time between diagnosis and operation was short. For patients with predominantly small-bowel disease it was 4 months and for patients with predominantly colonic involvement 8 months. The frequencies of preoperative and early postoperative complications were low compared with those in other reports. Local complications, such as intra-abdominal fistulae and abscesses, were preoperatively seen in only 4% of the patients. Arthritis, iritis, or erythema nodosum was not seen in patients with predominantly small-bowel disease. The early postoperative death rate was 1.5%, the late mortality rate related to Crohn's disease 2.3%. In conclusion, early resectional surgery seems to be justified as one form of treatment for Crohn's disease in that it diminishes the rate of serious complications. The risk of recurrence is, however, not influenced by early surgical intervention.
