摘要:

&NA;During a period of 12 years, 52 patients without tumor recurrence were treated for chronic radiation injury to the small bowel. Eighteen patients also had concomitant large bowel injuries. Forty‐seven patients were treated surgically, 42 of whom presented with obstruction, necrosis, or perforation of the bowel and had emergency operations. Thirty‐eight patients underwent wide resection of the injured bowel, and six had bypass procedures. Anastomotic leakage occurred in 6 percent of the patients. The operative morbidity rate was 34 percent, and the mortality rate, 9 percent. Based on this experience, when surgery for small intestinal radiation injury is mandatory, the procedure should be a generous small bowel resection whenever possible, and probably should be performed only by experienced surgeons.

摘要:

&NA;A review of 282 patients with carcinoma of the rectum treated by local excision suggests that some patients are best managed and perhaps preferably managed by local means.In situcancer is treated adequately by local excision regardless of size or grade. Well‐differentiated lesions, particularly those less than 3 cm in diameter, probably are managed best by local excision. Moderately or poorly differentiated lesions, regardless of size, probably are managed best by radical techniques until more information is available to document results with local excision.

摘要:

&NA;A retrospective review of 1888 colorectal cancer patients demonstrated 37 metachronous cancers in 30 patients for a metachronous cancer rate of 1.6 percent. Evaluation of the index cancers consisted of the traditional single‐contrast barium enema and proctoscopic evaluation. Forty percent of the metachronous cancers appeared within two years of the index cancer. If the minimum length of the polyp‐cancer sequence is three to five years, then this represents a failure of a traditional preoperative evaluation. A more sensitive evaluation potentially could decrease the metachronous cancer rate. Colonoscopy, which has been found to be more accurate in detecting synchronous neoplasms, should be included in the evaluation of all patients with colorectal cancers.

摘要:

&NA;In 282 patients, 731 colon polyps (643 adenomas and 88 hyperplastic polyps) were extirpated endoscopically or biopsied and investigated histologically. Localization of the adenomas with various degrees of atypia and the hyperplastic polyps, as well as their size distribution, were determined. In 66 patients with adenoma polypectomy on the first examination, one or more control colonoscopies were carried out (in all, 107). The median period of follow‐up observation was 31 months. Thirty percent of the one‐year control colonoscopies after polypectomy revealed new adenomas. The statistical analyses showed that patients with singular adenomas, on initial investigation, develop significantly fewer adenomas in the further course than patients with multiple initial findings, especially in negative results in the one‐year control. The size of new adenomas found during the first 24 months after polypectomy does not exceed 10 mm. On the basis of these results and the literature data available so far, a follow‐up program is presented for discussion.

摘要:

&NA;This study was carried out on 30 patients with symptomatic internal hemorrhoids and 20 normal controls. The anal sphincter pressure was studied before and after surgery. A significantly high anal pressure was found in all patients with symptomatic internal hemorrhoids, when compared with normal controls, and there was no relation between this increase and the degree of hemorrhoids. One week following surgery, this high pressure was reduced significantly and was not affected by the type of operation. Thus, this increase in resting anal pressure is due to an overactivity of the internal hemorrhoids, which is secondary to the presence of the hemorrhoidal mass.

摘要:

&NA;Eleven occurrences of common peroneal palsies following pelvic surgery for malignant conditions are reported. The patients' clinical course and possible mechanisms of nerve injury were reviewed. It was concluded that the current belief that all peripheral neuropathies occurring under general anesthesia are preventable may not be applicable to patients with pelvic cancer who must undergo tedious, lengthy, meticulous, extirpative surgery in the dorsal lithotomy position. In patients with tumors that are seemingly isolated to the pelvis, amenable for surgical resection, the possible risk of a peripheral nerve injury is superseded if beneficial effects are obtained by controlling the local manifestations of the tumor.

摘要:

&NA;Nine patients with fulminating amebic colitis who were treated surgically from 1975 to 1982 are presented. Only those who had bowel resections with exteriorization of the cut ends survived. The pertinent literature is reviewed briefly.
