Disorders of calcium metabolism are not generally considered important either clinically or pathophysiologically in essential hypertension. Recent reports, though, suggest that increased parathyroid gland function may be one of the more common endocrine disturbances associated with hypertension. We measured serum parathyroid hormone (PTH) concentrations as(More)
PURPOSE The aim of this study was to delineate the results, mortality, and morbidity of partial lateral internal sphincterotomy for the treatment of chronic anal fissure. METHOD A retrospective review of 500 patients undergoing partial lateral internal sphincterotomy for chronic anal fissure between 1980 and 1990 was performed. Patients were identified by(More)
Injury to the ureters is a serious complication of colonic and rectal surgery. The experience of the authors with routine use of ureteral catheters to minimize this complication is reviewed. It was found that there are minimal complications associated with their use. Injuries to the ureters were not completely avoided. However, unrecognized injuries (except(More)
PURPOSE This study was designed to assess the results of a minimally invasive surgical procedure for the correction of complete rectal prolapse in a poor surgical risk group. METHODS Over a ten-year period, 40 patients underwent 41 Delorme operations when advanced age and/or poor overall health mitigated against an abdominal approach. Mean age was 82(More)
Diabetes mellitus places a significant burden on the U.S. healthcare system. Because of the potential to reduce diabetic complications and costs through intensive management, diabetes has become a primary target for disease management programs. We performed a retrospective analysis of short-term baseline and follow-up clinical, economic, and member and(More)
The purpose of this report is to estimate diabetes prevalence and annual health care costs for people with diabetes in 1992, compare average annual costs for diabetics and nondiabetics, and estimate the portion of total U.S. health care expenditures incurred by people with the disease. Data from the 1987 National Medical Expenditure Survey were used to(More)
One hundred twenty-six patients underwent 130 end colostomies, 44 for benign and 86 for malignant disease, and were followed for an average of 35 months. The left or sigmoid colon was used in 99 and the transverse colon in 31. Stomas were made electively in 98 patients and urgently in 32. Seventy-six stomas were brought out through the incision and 54 from(More)
Lateral internal sphincterotomy proved to be effective in 99 per cent of the 418 procedures in which it was performed. The complication rate of 5 per cent was an improvement over most of the rates reported in the medical literature and over our previous experience with posterior sphincterotomy and anoplasty. Anal wounds and fissures healed faster than with(More)
Sixty-eight patients with rectal cancer treated by electrocoagulation are reviewed. All were followed up for a minimum of 5 years. The survival rate in patients with small exophytic cancers is greater than 70 percent. However, the recurrence rate after electrocoagulation is 40 percent. Electrocoagulation offers an alternative for the primary treatment of(More)
PURPOSE Controversy exists over the appropriate preoperative evaluation of colorectal cancer patients. Most surgeons agree that basic laboratory studies are indicated. Computerized tomography of the abdomen and pelvis has been used in our practice to augment the preoperative evaluation of these patients. METHODS One hundred fifty-eight consecutive(More)
