摘要:

&NA;One hundred twenty patients with primary retrorectal tumors (79 congenital, 14 neurogenic, 13 osseous, and 14 miscellaneous) had their initial treatment at the Mayo Clinic from 1960 to 1979. The mean age was 43 years (100 patients were adults). Female predominance was associated with congenital cysts (15:1) and male predominance with chordomas (5:1). Forty‐three percent of the patients had malignant lesions. No dermoid cysts were found in this series. Diagnosis was made by digital examination or sacral radiographs in all patients. Computed tomography scan was the most important diagnostic method; the rate of positive findings was 100 percent in 20 patients. Approach to the tumor was posterior in 79 of 102 patients in whom resection was possible. Ten of 66 patients with benign tumors had recurrence. The five‐year survival rate for patients with chordomas was 75 percent and for patients with other malignant lesions was 17 percent. Because preoperative biopsy can cause tumor spread, abscess, fecal fistula, or meningitis, it should not be performed if tumors are potentially resectable. Whenever possible, total resection should be done.

摘要:

&NA;Published guidelines from the Center for Disease Control (CDC) “strongly recommended” gas sterilization or 30 minutes of high‐level disinfection with either 2 percent glutaradehyde or 6 percent hydrogen peroxide following each flexible endoscope cleansing for proper care. The guidelines were proposed on the basis of previous CDC studies performed on glutaraldehyde disinfection of respiratory equipment. A prospective study was performed culturing flexible endoscopes following cannulation of the lower gastroinstestinal tract and cleansing. A uniform endoscope cleansing method without gas sterilization or high‐level disinfection was used between patients. Thirty aerobic and 30 anaerobic RODAC bacterial culturings revealed no obligate anaerobic organism growth and only sparse, aerobic, environmental and cutaneous organism growth. These were no instances of documented or suspected postendoscopy infectious complications. Our results indicate that high‐level disinfection and gas sterilization of flexible endoscopes are not necessary to prevent bacterial disease transmission from patient to patient.

摘要:

&NA;The records of all patients with familial polyposis coli and ulcerative colitis operated at The Mount Sinai Hospital were reviewed to determine the proportion of patients with cancer at the time of colon resection. Sixty‐nine patients with familial polyposis coli undergoing operation between 1947 and 1983 were identified and 25 (36 percent) were found to have cancer. In the group with ulcerative colitis, 548 patients had surgical treatment between 1957 and 1983 and 65 (12 percent) had colonic cancer. There was a significant decrease in the proportion of patients with familial polyposis coli having cancer at the time of colon resection from 50 percent before 1968 to 20 percent since 1978. This change in cancer incidence was found to correlate with a decrease in the mean age at operation from 40 to 25 years. In the group with ulcerative colitis, the mean age at operation has remained essentially unchanged at 36 years. The proportion of patients with ulcerative colitis having cancer at the time of colon resection has remained constant throughout this study. Progression to carcinoma is still a significant concern in both familial polyposis coli and ulcerative colitis. Although removal of the colon and rectum prevents cancer development, patient selection and timing of the operation remain a difficult problem.

摘要:

&NA;The records of 102 patients with levator syndromes were reviewed. All had failed trials of conservative management prior to treatments with electrogalvanic stimulation. The symptoms of 12 patients were subsequently found not to be due to levator syndrome. Of 90 patients with correct diagnoses, 77 percent were relieved or improved after courses of electrogalvanic stimulation, a valuable adjunct to the management of this frustrating condition.
