摘要:

&NA;Despite many similarities to colorectal cancer in adults, the rare childhood form has some peculiarities. Childhood mortality is greater among Negroes than Caucasians, particularly in boys, reflecting the rising incidence of this tumor in the young Negro population. In addition, the percentage of childhood cases with precancerous diseases (polyposis, colitis) appears greater than in adults. Most striking is the high percentage of mucin‐producing tumors in young people with colorectal cancer. The mucoid tumors tend to occur after the age of 10 years, whereas younger children are more likely to develop non‐mucoid carcinoma in an adenomatous polyp.

摘要:

&NA;We have reviewed the experience of St. Mark's Hospital with double synchronous cancers of the large intestine. This occurs in 3.5 per cent of cancer resections, and in 75 per cent there are associated benign neoplasms. Patients with double or treble cancers fare much the same as those with single cancers, and the prognosis appears to be surprisingly favorable, even when the second growth is comparatively advanced. The second lesion, however, is usually not palpable at operation, and full clinical and radiologic investigation is therefore essential before any resection is undertaken for cancer of the colon or rectum.

摘要:

&NA;Results after operations for acute obstruction of the large intestine due to cancer were analyzed during a 10‐year period and compared with the results after operations for nonobstructive tumors during the same period. The following conclusions could be deduced: 1) Cancer is more often obstructive in the colon than in the rectum. Cancers of the splenic flexure are relatively more often obstructive than cancers in other parts of the colon. 2) Postoperative morbidity (and probably mortality) is higher and the five‐year survival shorter in patients with obstructive cancers of the large intestine than in those without obstruction. Obstructive Dukes' A tumors are very few. 3) The early morbidity and mortality after acute cecostomy are probably not higher than after acute transversostomy, if the cecostomy wound is left open. The cecostomy carries a risk of peritoneal contamination. 4) Cecostomy does not relieve obstruction in 5‐10 per cent of the patients, while transversotomy seems always to be effective. Emergency exploratory laparotomy for obstructive cancer of the large bowel instead of a blind cecostomy reduces the number of patients who need two operations by 10 per cent. 5) Hernias are frequent at the sites of previous spontaneously closed cecostomies. 6) Antibiotic bowel preparation seems not to be effective shortly after decompressive colostomy.

摘要:

&NA;The use of the Warren vaginal flap operation for repair of a traumatic deformity consisting of disruption of the perineal body, anterior segment of the external anal sphincter, and lower half of the rectovaginal septum is described. Modifications described in this article include use of the jackknife position to give better exposure and epinephrine infiltration to give a bloodless field. The incidences of infection and recurrence appear lower than with the layer technique.
