摘要:

&NA;Problems associated with the nipple valve of the continent ileostomy continue to be a major obstacle, frequently necessitating reoperation, with ongoing incontinence persisting in some patients. We have constructed a continent ileostomy in a dog using a three‐loop reservoir, continence being maintained by placing a porcine aortic valve in the efferent loop of the reservoir, obviating the need for the nipple valve. A detailed description of the technique is given. Possibilities for its application to particular clinical problems are discussed.

摘要:

&NA;Preoperative levels of perchloric acid extractable plasma CEA were measured in 911 patients with complaints of the digestive system. A final diagnosis of benign disease was made for 579 patients; 332 patients were found to have cancer. Data for the preoperative CEA values were examined for clinical significance as an aide to diagnosis, preoperative disease staging, and prognosis.The results of our analysis support the conclusions of many investigators that the CEA assay is not a clinically useful diagnostic test, but it shows limited value in preoperative staging and a somewhat stronger correlation with prognosis.

摘要:

&NA;Four prognostic factors,i.e., site of the tumors, mode of presentation, duration of symptoms, and pathologic staging, were correlated to the results of surgical treatment,i.e., curative resectability, postoperative complications and mortality, and five‐year survival, in 161 patients operated upon for colorectal cancer.Only 31 (19 per cent) of the growths were right‐sided; 71 patients (44 per cent) had symptoms less than six months. Fifty‐four of them had a localized cancer; a radical procedure was performed in 114 (71 per cent), and postoperative complications occurred in 42 cases (26 per cent). The overall crude five‐year survival was 38 per cent (53 of the 140 followed‐up patients).The length of the clinical history did not correlate with the pathologic staging, which greatly influenced curability and survival.A statistically significant poorer prognosis was observed in patients with left‐sided tumors, with an emergency presentation and with a duration of symptoms shorter than six months.A better prognosis can be achieved by means of a presymptomatic diagnosis.

摘要:

&NA;A retrospective study was undertaken, evaluating 54 patients who underwent 57 Ripstein procedures at the Cleveland Clinic Foundation during the years 1963‐1978. The patients were evaluated for their preoperative characteristics as well as early and late postoperative results. Patients who experience procidentia are generally middle‐aged women who have had significant disorders of bowel function. Although the operative mortality was zero, and the majority of patients were satisfied with the results of their Ripstein procedure, there was significant operative morbidity (26 per cent). Twelve and one‐half per cent of patients had recurrent rectal prolapse, and 18 per cent of patients had significant long‐term obstructive symptoms. The Ripstein procedure still remains the treatment of choice for rectal prolapse.

摘要:

&NA;Plasma CEA levels were determined in 280 patients with histologically proven colorectal carcinoma: in 180 once or twice preoperatively and repeatedly postoperatively, and in 100 postoperatively only. Preoperative levels correlated directly with surgical‐pathologic state and inversely with the time of recurrence;i.e., groups of patients with more advanced stage showed higher proportion of elevated CEA levels, and patients with higher levels had recurrences earlier. Levels above 20 ng/ml were strongly suggestive of liver metastases or disseminated disease.Postoperative plasma CEA levels displayed three patterns of variation. 1) Levels fluctuating within normal range, below 3.2 ng/ml, strongly evidenced that surgery was effective, and 2) those fluctuating below 7.5 ng/ml indicated usually nonmalignant concomitant disease; in either group no more than 10 per cent of the patients had recurrences. 3) Levels rising persistently from a postoperative nadir indicated recurrence or, when the rise was dramatic, liver metastases or disseminated cancer in at least 97 per cent of the patients.
