The Acute Physiologic Score and Chronic Health Evaluation (APACHE) II and the Simplified Acute Physiologic Scale (SAPS) II are two of the more commonly employed predictors of outcome and performance in the intensive care unit setting. However, controversy persists about whether the scores generated by these systems have similar predictive value. This study compared the predicted mortalities derived from APACHE II and SAPS II and contrasted them to the actual mortality in a surgical intensive care unit (SICU). Data for 1665 patients admitted to the SICU between July 1994 and August 1997 were entered into an SICU computerized database. From recorded demographic, hemodynamic, and laboratory data, APACHE II and SAPS II scores were obtained with corresponding predicted mortalities. Patients were stratified by age into categories of less than and greater than 65 years old. Predicted mortalities by APACHE II and SAPS II were compared for each group. An additional analysis included a comparison of survivors and nonsurvivors. There was no significant difference in predicted mortality between APACHE II and SAPS II in any of the groups. Actual mortality was 30 of 486 (6.2%) in patients less than 65 years of age and 73 of 1179 (6.2%) in patients 65 years of age or greater. The APACHE II and SAPS II predicted mortalities (mean +/- SD) for patients less than 65 years of age were 10.5% +/- 10.6% and 10.9% +/- 13.3%, respectively (P > .05). The APACHE II and SAPS II predicted mortalities in patients 65 years of age or greater were 19.1% +/- 17.8% and 18.7% +/- 21.0%, respectively (P > .05). Similarly, when patients were stratified by survival status, no significant difference was present between groups. However, in individual patients, a difference between APACHE II and SAPS II scores was often present. We conclude that although disparities between APACHE II and SAPS II predicted mortalities in individual patients may be significant, APACHE II and SAPS II have similar predictive value in a large SICU patient population. However, both APACHE II and SAPS II systems overestimate mortality in SICU patients. Based on our results, we conclude that either system can be used to measure quality of care in the SICU; however, neither system can be reliably applied to a single patient.

Torsion of the gallbladder is an extremely rare cause of acute surgical abdomen. Although gallbladder torsion has been reported the diagnosis remains elusive and is often missed. A case of necrotizing gallbladder torsion is examined, and the literature is reviewed by the authors. History peak incidence and pathophysiology are discussed, and possible risk factors are identified. We conclude that torsion of the gallbladder is a condition that has minimal clinical findings.

BACKGROUND: Radiographic diagnosis of acute cholecystitis can be established using ultrasonography (US), cholecystoscintigraphy (HIDA), or both. Although both modalities have been effective in diagnosing acute cholecystitis (AC), physicians from the emergency department and admitting surgeons continue to request both tests in an attempt to increase the diagnostic accuracy of AC. This article reports the institutional experience of a large tertiary care health care facility, with respect to the sensitivity of US, HIDA, and combined US and HIDA. STUDY DESIGN: We conducted a retrospective review of 132 patients diagnosed with AC who underwent laparoscopic cholecystectomy during the same hospitalization. Patients were stratified into three groups: Group 1 (Gp1, n = 50) included patients who underwent US alone, group 2 (Gp2, n = 28) included patients who underwent HIDA scan alone, and group 3 (Gp3, n = 54) included patients who underwent both US and HIDA. RESULTS: The three groups did not differ with respect to age, liver chemistry, time to operation, and hospital length of stay. The sensitivity of US, HIDA, and combined US/HIDA as diagnostic modalities for acute cholecystitis was referenced to histopathologic confirmation. Sensitivity was 24 of 50 (48%), 24 of 28 (86%), and 49 of 54 (90%) for US, HIDA, and the combination of US/HIDA, respectively. CONCLUSIONS: HIDA scan is a more sensitive test than US in diagnosing patients with AC. Based on the results of this study, we recommend that HIDA scan should be used as the first diagnostic modality in patients with suspected acute cholecystitis; US should be used to confirm the presence of gallbladder stones rather than to diagnose AC.

Atheromatous disease of the aorta significantly increases morbidity and mortality during coronary revascularization. The surgical approach must be modified for patients in whom this condition is identified. In this report, we describe a technique that uses bilateral internal thoracic arteries as composite grafts with reverse saphenous veins. The operation is performed without cardiopulmonary bypass. We report the cases of 2 patients who underwent this procedure. Neither patient experienced signs or symptoms of atheromatous embolization, and there was no perioperative morbidity or mortality. Off-pump myocardial revascularization using bilateral internal thoracic arteries is an attractive surgical approach for patients who have atheromatous aortas or other conditions in which it is advantageous to avoid aortic manipulation, cannulation, cross-clamping, and cardiopulmonary bypass.

BACKGROUND: The role and timing of endoscopic retrograde cholangiopancreatography (ERCP) in patients with suspected choledocholethiasis remains a controversial subject. There have been few studies exploring the role of intraoperative ERCP. Therefore, we set out to perform a retrospective review of 29 patients who underwent combined laparoscopic cholecystectomy (LC) and intraoperative ERCP (LC/ERCP). Our objective was to assess the feasibility of a one-stage approach using intraoperative ERCP. METHODS: We identified 29 patients in whom LC/ERCP was attempted between January 1996 and November 1998 at a university-affiliated hospital with a large private faculty. Parameters reviewed included preoperative diagnosis, liver function tests (LFT), finding on transcystic cholangiogram (TCC), ERCP, stone retrieval, failure of ERCP, length of stay, morbidity, and mortality. RESULTS: Twenty-eight of 29 patients (97%) underwent successful combined LC/ERCP. Successful TCC followed by ERCP was performed in 21 of 26 patients (81%). Five TCC were technically unsuccessful; in these patients, ERCP was performed on the basis of preoperative criteria. In three patients, TCC was not attempted. Stones were successfully retrieved from 20 of 21 patients (95%) with abnormal finding on TCC, one of five patients (20%) with failed TCC, and two of three patients (67%) with ERCP but without TCC. Overall morbidity was 14%, comprising two patients with postoperative hyperamylasemia and two with cystic duct leaks. There were no deaths in the group. The mean time for the combined procedure was 173 min (range, 50-290). Mean length of hospitalization was 3.4 days, and mean postoperative stay was 2.2 days. CONCLUSIONS: LC/ERCP can be performed safely. The advantages of the combined procedures include one-stage treatment of cholelithiasis and choledocholithiasis, avoidance of unnecessary preoperative ERCP and their concomitant complications, and elimination of potential return to the operating room when postoperative ERCP is technically impossible.

Congenital anomalies of the aortic valve can be associated with other cardiac anomalies. In this report, we present a patient with an aortic valve anomaly associated with occlusion of left coronary ostia. In addition, we reviewed the literature and found 10 similar cases. Although compatible with life, this anomaly can lead to significant symptoms. Preoperative diagnosis as well as proper therapeutic planning should be tailored to correct valvular competence and restore coronary blood flow.

Aneurysm of reverse aortocoronary saphenous vein graft is a known complication of coronary artery bypass grafting. In this report we present a case of a 60-year-old man who presented 12 years after coronary artery bypass grafting with a giant graft aneurysm of the reverse aortocoronary saphenous vein graft to the right coronary artery, compressing the right atrium. Spiral computed tomography was used to identify the aneurysm measuring 7 x 6 x 7 cm. We also reviewed the English-language literature and found reports of 50 patients with similar aneurysms of which 30 (61%) were identified as true aneurysms and 17 (33%) were identified as pseudoaneurysms. Three patients could not be identified into either group. We reviewed the presenting symptoms, diagnostic tools, and treatment options for this rare entity. An understanding of the pathophysiology of reverse aortocoronary saphenous vein graft aneurysm is important to prevent the possibility of aneurysm rupture, embolization, myocardial infarction, or death.
