Abdominal surgery in patients undergoing chronic hemodialysis.

The reports on surgical techniques that specifically focus on the management and outcome of patients on chronic hemodialysis (CHD) who undergo major intra-abdominal procedures--particularly of an emergency nature--are few. It is hoped that by analysis of our experience the nature of the problem can be further clarified and guidelines for clinical care can be formulated. Thirty-two cases which encompass a 7-year period (1978 to 1985), were reviewed. Seventeen patients underwent elective surgery and fifteen underwent emergency intervention. There was a wide range of cases that were similar to those most generally seen in an acute-care teaching hospital. The morbidity and mortality rates in elective surgery patients were 12% and 6%, respectively, while in the emergency cases, these rates were 62% and 47%. Patients with diabetes had the highest morbidity and mortality. These results were analyzed, and we conclude that CHD patients at risk with a surgically correctable condition should be considered for elective intervention, even if they are currently free of symptoms. This may be particularly true for CHD patients with diabetes.

The prognostic and therapeutic value of frozen section determinations in the surgical treatment of squamous carcinoma of the head and neck.

The records of 216 patients with squamous cell carcinoma of the oral cavity, oropharynx, and hypopharynx treated by surgery alone were reviewed. Frozen section control at the time of the surgical procedure was used to evaluate the margins of the excision. Findings at frozen section were correlated with local control and survival. The inability of the surgeon to obtain clear margins by frozen section for whatever reason resulted in a very high incidence of local recurrence and death. The fact that the patient's tumor could be removed with free margins at the time of surgery did not guarantee long-term success, although the frozen section technic did prove to be reliable and an effective tool for evaluating the patient's prognosis and the efficacy of the surgical procedure.

Cost-effective diagnostic test sequencing.

Proper diagnostic test selection and logical sequencing can minimize cost without compromising care. This study analyzes the logic for sequencing tests either in series (one after another) or in parallel (simultaneously). A model is created using 2 diagnostic tests for 2 diseases. Tests are assumed to have perfect performance characteristics. Factors involved in cost-effective test sequencing include cost of each test, test performance characteristics, per diem hospital charge, and the clinician's prior probability of the suspected diagnosis based on history, physical examination, and previous laboratory data. At a given point of clinical suspicion, cost-effective sequencing strategy should shift. In general, a cheap test can effectively be used in parallel even at low diagnostic probabilities; an expensive test should, in general, be used in series only when there is a high prior probability of diagnosis. High per diem hospitalization costs--such as for a patient in the intensive care unit--favor in parallel testing. Clinical acumen and suspicion of diagnosis (prior probability) primarily direct cost-effective diagnostic test sequencing. Decision analysis of diagnostic test sequencing represents a technique for making cost-effective decisions for sequencing and, thereby, minimizing costs while achieving optimal patient care.
