摘要:

&NA;From 1949 to 1977, 39 patients with localized malignant retrorectal tumors were treated at Memorial Sloan‐Kettering Cancer Center. Chordomas were the most frequent histologic type (38 per cent of patients) followed by neurogenic tumors (15 per cent) chondrosarcomas, hemangiopericytomas, and embryonal adenocarcinomas (8 per cent each). Treatment consisted of surgical excision in 28 patients (18 of whom received adjuvant radiotherapy and/or chemotherapy). Ten patients were treated nonsurgically, receiving radiation and/or chemotherapy alone.Large tumors were most successfully managed by a combined surgical approach consisting of exploratory celiotomy, rectal mobilization, and bilateral hypogastric artery (with middle sacral artery and vein) ligation, followed by transsacral tumor excision with incontinuity sacrectomy.For all treated patients, survival at 5, 10, 15 and 20 years was 69 per cent, 50 per cent, 37 per cent and 20 per cent, respectively. Long‐term disease‐free survival (17 to 25 years post treatment) was noted in six patients

摘要:

&NA;Appendices removed from 100 healthy Nigerian Igbo women during elective cesarean operation and examined microscopically as three random cross sections showed that lesions categorized as luminal pus, luminal fibrosis, mucosal ulceration, muscular inflammation, crypt abscess and crypt necrosis were present in numerous sections. As elsewhere, these asymptomatic patients might have had clinical acute appendicitis in the puerperium. To explain the possible outcome in the rest of such patients, The crypt of Lieberkühn was advanced as a researchworthy histopathologic unit. Thus, in the natural history of the disease, both crypt abscess and crypt necrosis are contrastable bipolar lesions. In all probability, worldwide research on these intriguing lesions will reveal crucial clues to one or more facets of the pathogenesis of appendicitis.

摘要:

&NA;Sigmoid volvulus is often a surgical emergency. The diagnosis is usually reached on the basis of both clinical and radiolotic assessment. A review of the radiologic findings in 20 patients diagnosed as having sigmoid volvulus is presented. Typical radiographic features are illustrated. Reasons for their absence in certain cases are discussed.

摘要:

&NA;Between 1970 and 1980, 12 patients were admitted 16 times to San Bernardino County Medical Center for sigmoid volvulus. The seven men and five women averaged 68.5 years old. Sixty‐seven per cent recounted histories of neuropsychiatric disorders. Fifty per cent had been institutionalized. Forty‐two per cent had endured previous episodes of sigmoid volvulus. Fourteen of 24 nonoperative attempts at reduction were successful but were followed by nine recurrences. Ten of 12 patients eventually underwent surgery. Eight procedures were electively scheduled following spontaneous or nonoperative reductions. Two emergency procedures for gangrenous colons were required. Both of these patients died. Mortality following elective surgery was 25 per cent. Twenty‐nine major complications followed the ten procedures. All ten patients underwent sigmoid resections. Follow‐up disclosed only two living patients. Only five had survived one year following initial hospitalization and only two for two years. The high mortality of this and other American series was attributed to the frail nature of the elderly, debilitated, institutionalized patients with neuropsychiatric and multiple medical disorders, who develop sigmoid volvulus in the United States.

摘要:

&NA;Four hundred seventeen asymptomatic patients with an average age of 52 years underwent screening flexible fiberoptic sigmoidoscopy. Seventy‐three polyps were detected in 52 patients with a 17.5 per cent detection rate. Half were above 25 cm and one‐third were greater than 1.0 cm in size.Biannual follow‐up of these patients is planned to determine the efficacy of this screening procedure combined with removal of all polyps in preventing the development of colorectal cancer.

摘要:

&NA;A report of the history and management of colonic cancer in two brothers with Cancer Family Syndrome is presented. An analysis is made of the prevalence of colonic and endometrial cancer in this family. The risk to the progeny of affected and unaffected individuals is discussed, and recommendations for screening for early signs of cancer are offered.

摘要:

&NA;A patient is described in whom a segment of colon used to construct an artificial vagina was therefore removed from intestinal continuity and was affected by typical idiopathic ulcerative colitis. The onset of disease was simulatneous in this loop of colon and in the rectum. There was no evidence of local infection. An increased ratio of IgE‐plasma cells was found in both the mucosa of the grafted colon and that of the rectum, but anticolonic antibodies were not detected in the serum. After removal of the loop of colon used for colpopoiesis, the patient continued to suffer from distal proctocolitis for almost a year, but has since then maintained a stable remission without treatment. The etiology of ulcerative colitis is discussed, and attention is drawn to the unusual psychologic aspects of this case.
