Summary and ConclusionsThere were ten additional patients in whom ulcerative colitis was complicated by cancer of the colon. A total of 33 patients with carcinoma of the colon among approximately 1,200 patients with ulcerative colitis have been identified. Seven of the ten are dead. The average age when cancer appeared was 44 years and malignancy was diagnosed after an average duration of ulcerative colitis of 17 years. The distribution of carcinoma was more diffuse throughout the colon in ulcerative colitis than that in the case ofordinarycancer of the large bowel. The neoplasia frequently was multifocal, presented variable histopathologic characteristics, and involved new sites in the colon after removal of the initial tumor. Involvement of lymph nodes was present in most cases, but it did not exclude the possibility of prolonged periods of survival.

摘要:

ConclusionsThere can be no doubt that carcinoma of the colon may cause distention of the appendix, but how often such distention actually leads to acute appendicitis is not clear.The chance of overlooking an occult carcinoma of the colon is not sufficiently great to warrant discontinuing the use of a McBurney type incision in the elderly patient with acute appendicitis.

摘要:

Summary and ConclusionsIn this excellent presentation, a report is made of the well‐established role ofT. cruziin the etiology of acquired megacolon in South America. The chief difference from the distal aganglionosis of Hirschsprung's disease is that, in acquired megacolon of Chagas' disease, there are degenerative changes and quantitative reduction in the intramural ganglia of the entire intestinal tract. To stimuli, there is a hypersensitive response of the denervated muscle layer which becomes hypertrophic and lacking in propulsive efficiency owing to its in‐coordinate contractions (aperistalsis). The result is fecal stasis, dilatation and finally hypoxic atony. Clinical and radiologic features, surgical management, complications and clinical results are presented with clarity.Brief remarks are made concerning removal of various segments of the colon, surgical management of total megacolon and problems relating to acute volvulus of the sigmoid flexure.There were no operative deaths in a series of 100 cases. The actual aim of treatment is correction or palliation of obstipation and although results proved to be good in about 70 per cent of traced patients, the chances of recurrence cannot be predicted because neuronal destruction in the remainder of the intestine is irreversible and the surgeon cannot determine its extent.
