摘要:

In a retrospective study to correlate preoperative ultrasonic findings with operative findings in 80 patients with symptoms of biliary tract disease, ultrasound was 75% accurate in predicting the presence or absence of gallstones. Of all positive ultrasonic studies, 95% correlated with gallbladder disease of some kind. The diseased gallbladder without stones may still produce ultrasonic abnormalities, allowing detection of inflammatory changes. Ultrasound is indicated in acute conditions of the abdomen, in patients with jaundice or allergy to contrast agents, and as an adjunct to other diagnostic modalities.

摘要:

To determine the value of preoperative blood typing and crossmatching, we reviewed the transfusion needs of 100 consecutive patients who had elective cholecystectomy in a city-county teaching hospital. One hundred forty-eight units of blood were typed and crossmatched for 76 patients (1.48 units/patient). Blood was typed and screened for seven patients. Six units were transfused into four patients (two patients postoperatively). None required intraoperative transfusion for hemorrhage or shock. Total blood use was 4%, with a mean of 0.06 units per patient. Substituting the type and screen for a type and crossmatch would have saved approximately $2,108 and 16.6 technician hours in this group and, if applied nationally, $9 million and 72,000 technician hours each year. In addition to sizeable savings, more efficient blood use would result from use of the type and screen in elective cholecystectomy, with no increase in patient risk.

摘要:

To study the efficacy of several commonly used peritoneal lavage solutions in the treatment of experimental fecal peritonitis, lethal peritonitis was created in 100 rats by placing a gelatin capsule containing 0.1 ml of human stool and barium sulfate within the abdominal cavity. At reoperation up to eight hours after implantation, the rats had initial lavage with 30 ml/kg of sterile normal saline, followed by 15 ml/kg of one of four treatment regimens, all colored alike. These were 10% povidone-iodine (PVP-I), 1% PVP-I, 0.1% kanamycin, and sterile normal saline. A fifth group did not receive a second lavage. All survivors were sacrificed on the ninth day, at which time the study was unblinded. Twelve hours postoperatively there was a significantly greater mortality in the group irrigated with 10% PVP-I (83%) compared to all other groups (0–6%). At nine days, only the kanamycin group had survivors (29%); this was significantly better than any other group.

摘要:

Jejunoileal diverticulosis, an uncommon bowel disorder afflicting the elderly, may be asymptomatic, cause nonspecific upper gastrointestinal symptoms, or lead to panmalabsorption. Perforation, hemorrhage, and obstruction are life-threatening acute complications. Ten patients with Jejunoileal diverticulosis diagnosed during the past nine years at the Medical College of Virginia are reported and include examples of each of the three major acute complications. Adequate preoperative assessment and preparation combined with timely resection offer the best chance for a favorable outcome.

摘要:

In evaluating results of carotid phonoangiography (CPA) and Oculoplethysmography (OPG) in 53 patients who had carotid arteriography, we found the accuracy of CPA to be 61% and the accuracy of OPG, 60.4%. Until future investigation clarifies significant differences in the reported results of CPA and OPG, these tests cannot be recommended for reliable, noninvasive evaluation of extracranial carotid occlusive disease.

摘要:

At Ochsner Medical Institutions from 1970 to 1979, 96 patients who had previously had myocardial revascularization later had a total of 136 noncardiac operations. There were no postoperative myocardial infarctions and only one noncardiac death. Transitory postoperative arrhythmias occurred in 3.6% of patients. It appears that myocardial revascularization protects the cardiac patient from myocardial infarction and cardiac-related deaths during and after noncardiac operations. Patients with cardiac disease scheduled for elective surgery should have exercise testing or coronary cineangiography or both to evaluate the severity and significance of the coronary disease. If significant coronary lesions are demonstrated that are amenable to a bypass procedure, the operative risk will be lessened by prior myocardial revascularization.
