Background: Laparoscopic Nissen fundoplication (LNF) provides long-term improvement in the typical symptoms of gastroesophageal reflux disease. Few studies have prospectively addressed LNF in the community hospital or the effect of LNF on specific atypical symptoms, other related gastrointestinal symptoms, and weight change., Methods: Data were collected prospectively on consecutive patients having LNF. Three typical, 6 atypical, and 3 other gastrointestinal symptoms were studied., Results: Short-term data on 91 patients and long-term data on 84 patients were studied. Overall long-term improvement was 98%. Regarding typical symptoms, the greatest improvement occurred in heartburn and regurgitation. Regarding atypical symptoms, the greatest improvement occurred in cough and sore throat, but chest pain, hoarseness, and throat clearing also showed significant durable improvement. Bloating, nausea, and diarrhea showed no significant change from preoperative to postoperative surveys. Mild weight loss was common., Conclusion: LNF can be safely performed in a community hospital with results equal to those of university hospitals. Improvement in typical symptoms was greater than improvement in atypical symptoms, but results for both were significant and durable. Nonspecific gastrointestinal symptoms, such as nausea, bloating, and diarrhea, may be unrelated to Nissen fundoplication.

Background: Carotid body tumors (CBT) are rare, infrequently malignant vascular neoplasms that are near the carotid bifurcation. Surgical excision is the treatment of choice, but individual surgeons or an institution cannot accumulate sufficient expertise to evaluate their outcomes with confidence. Our purpose was to report outcomes of surgical procedures for CBT from a nationwide dataset., Study Design: Data were retrieved from the Nationwide Inpatient Sample from nonfederal hospital discharge abstracts. Data were queried for ICD-9-CM code 39.8, operations on the carotid body and vascular bodies, and code 38.2, carotid endarterectomy. Outcomes analyzed were length of stay, charges, and in-hospital mortality., Results: An estmated 4,601 operations were identified, 3,746 for CBT surgical procedures only, and in 855 a carotid endarterectomy was also performed. Overall morbidity was 3.3%. Mortality with CBT alone was 2.0% but was 8.8% if carotid endarterectomy was also performed. CBT surgical procedures are most commonly performed in western states where higher elevations are found. Women constituted 59% of the population; mortality for women was higher than for men (12.4% versus 7.9%). Mortality in urban teaching hospitals was 2.1% and in nonteaching hospitals 4.9%., Conclusions: CBT surgical procedures are rare but are performed across a broad age spectrum. Mortality rate is low for patients having CBT alone but rises when CE is added. Women are more commonly affected and fare less well. Addition of CE to CBT surgical procedures and the resulting poor outcomes have not been previously described. Consideration should be given to referral of CBT patients to hospitals where mortality rates are low.

Background: Ductal cancer in situ (DCIS) is an increasingly frequent diagnosis in breast cancer, and management continues to challenge surgeons and oncologists. The purpose of our study was to examine local and national rates of breast conservation surgery and breast reconstruction surgery and to explore patient and surgeon factors associated with the procedures., Methods: Review of the 1,342 patients in our institutional breast cancer database yielded 211 patients with DCIS. The sample of 211 patients was compared with a national (Nationwide Inpatient Sample [NIS]) database. Patient and surgeon factors associated with the use of breast conservative surgery (BCS) and breast reconstruction (BR) postmastectomy were identified., Results: At our institution, the use of BCS steadily increased over ten years. Younger women with nonpalpable tumors, nonprivate insurance, and younger surgeons were more likely to have BCS. In 28 patients, breast reconstruction was performed: younger Caucasian women with private insurance and younger surgeons were more likely to undergo reconstruction. NIS data revealed that BCS was performed in 20% but that BCS did not increase over the 12-year period., Conclusions: There was a steady increase in the use of BCS for DCIS at our institution, but a consistent, and much lower, use nationally. To increase breast conservation and reconstruction for DCIS, educational efforts should especially be directed toward elderly women and elderly surgeons.

African-American (AA) women have a higher mortality from breast cancer than Caucasians (C). This may be attributed to stage of disease at presentation, but specific prognostic factors are not well identified. We sought to identify prognostic factors in our database of early-stage (stage I and II) breast cancer from 1990 to 1999. There were 153 tumors in 150 AA women and 773 tumors in 760 C women. Prognostic factors are listed according to race with relative risk (RR) and 95 per cent confidence intervals. AA women presented significantly more often than C women under the age of 50 years (RR = 1.8) with palpable disease (RR = 1.3), higher-grade tumors (RR = 1.5), more estrogen receptor-negative disease (RR = 1.7), more progesterone receptor-negative disease (RR = 1.4), higher proliferation indices (RR = 1.9), and more lymph node-positive disease (RR = 1.6). Many of these adverse prognostic features persisted in "good" prognostic groups, i.e., those women over the age of 50 years with tumors <20 mm and having node-negative disease. We conclude that prognostic factors are related to race with AA women presenting at an earlier age and more often with palpable disease. More importantly AA women presented significantly more often with higher-grade tumors, hormone receptor-negative tumors, higher proliferation indices, and node-positive disease. These findings may explain a higher breast cancer mortality in AA women.

Background: Recent publications suggest an inverse relationship between mortality rates in the Whipple procedure for periampullary cancer and hospital volume/teaching status., Methods: The Nationwide Inpatient Sample database from 1988 to 1995, containing 24926 patients undergoing pancreatectomy for periampullary cancer, was used., Results: The mean number of procedures per hospital per year was 1.5, and the overall mortality was 14%. The volume of procedures per year increased from the rural to the urban nonteaching hospitals to the urban teaching hospitals (.6, 1.1, and 2.7, respectively), with a steady decrease in mortality among the three hospital types (18%, 15%, and 11%). A multiple logistic regression model with mortality odds ratios (ORs) showed that male sex (OR, 1.3), increasing age (OR, 1.6 to 6.7 in decades from 50 to > or=80 vs. <50 years), emergency admission (OR, 1.5), and hospital volume (less than one vs. one or more cases per year; OR, 1.5) were significantly predictive for increased in-hospital mortality., Conclusions: In-hospital mortality in the low-volume hospital setting is prohibitive, and review of each institution's mortality rates must occur before these procedures are performed in those institutions. In addition, patients over the age of 60 years, male patients, and those with an urgent admission are at a significant risk of in-hospital death, and consideration should be given toward transfer to an experienced institution.

Background: Indications for laparoscopic appendectomy (LA) remain controversial and poorly defined. We sought to identify indications for LA through a comparison of LA and open appendectomies (OA)., Methods: We reviewed demographics, coexisting medical conditions, radiology and pathology data, hospital course, and complications from charts on all LA patients and a comparison group of OA done from 1991 to 1998., Results: The following were significantly associated with LA: female sex, higher mean body mass index (BMI), coexisting medical problems, private insurance, and daytime surgery. The OA group was significantly more likely to have: a radiology report suggesting the diagnosis of acute appendicitis, perforation of the appendix, intensive care unit admission, and complications in their hospital course. Forty-one percent of the LA patients did not have appendicitis, compared with 20% of the OA patients., Conclusions: Daytime surgery, women, private insurance, coexisting medical problems, prior abdominal surgery, higher BMI, and less severe disease appear to be used by surgeons as indicators for LA. The threshold for surgical exploration appears to be lower for LA.

Background: 3% of the population is morbidly obese and experience many associated medical problems. Surgical procedures have been shown to achieve sustained weight loss not attainable by other measures, lessening the co-morbidities. However, most general surgeons have been reluctant to expand their practice to include bariatric surgery. The current study demonstrates the benefits of including bariatric surgery in a general surgeon's practice in a community hospital., Methods: Hospital charts of patients undergoing a gastric bypass procedure between 1997 and 2000 were reviewed. Demographic data, co-morbid conditions, intra-operative times, and post-operative weight loss were recorded. Follow-up data was obtained using a mailed survey based on the BAROS survey., Results: 168 patients underwent a Roux-en-Y gastric bypass procedure. Follow-up was obtained for 86 patients. Average pre-operative weight was 141 kg (BMI = 50). There was an average loss of 55% of excess weight by the second post-operative year. Operative times decreased as the number of the procedures performed by the surgeon increased. Over half of the patients surveyed reported improvements for each of the co-morbid conditions that were assessed (i.e., diabetes, back pain, etc.). Five categories of quality of life were assessed, and over 66% of patients reported improvements in all areas. In 44% of the patients, payment was obtained from private insurance and 56% from Medicare or Medicaid. There were no deaths., Conclusion: Adding bariatric surgery to a general surgeon's practice in the community setting can be beneficial to patients, intellectually stimulating and emotionally rewarding for the surgeon, and economically feasible for the institution.

Large, randomized prospective clinical trials have not addressed the safety of reoperation for recurrent carotid disease. Our purpose was to determine whether outcomes for carotid endarterectomy for recurrent disease were different from those for primary or contralateral carotid endarterectomy. We reviewed all carotid endarterectomies done in our regional medical center hospital from 1979 through 1997. We analyzed 1656 primary procedures, 377 contralateral carotid procedures, and 63 reoperations. Operation for recurrent disease was done in 3 per cent of those having primary operations. Patients in the three groups did not differ significantly with regard to age, race, or sex. Seventy per cent of patients were symptomatic with transient ischemic attacks, amaurosis, and reversible ischemic neurological deficit being most prominent. There were no deaths and three strokes in the reoperation group for a combined stroke and death rate of 4.8 per cent. This was not significantly different from that of 3.2 per cent for the stroke and death rate for the primary group and 3.5 per cent for the contralateral group. Carotid endarterectomy is a safe treatment for recurrent carotid artery disease.

Although the incidence of carotid atheromatous disease is presumably equal between the right and left carotid arteries, right and left carotid endarterectomies (CEs) may not be performed with equal frequency on the two sides. This study sought to examine whether right and left CEs are performed with equal frequency and whether there are any differences in outcome between these groups. Detailed chart review was performed on all CEs performed from 1979 through 1998 at our institution, and those lacking side data were excluded. Data were collected on the side of the procedure, demographics, comorbid conditions, details of the procedure, hospital stay, and major complications. The surgeons performing CE were surveyed about their practice of considering side factors. CE was performed on the left in 1190 (52%) of 2305 procedures; 1115 (48%) of the procedures were right CEs. This difference is statistically significant (P = 0.014). No significant differences in demographics, comorbidity, presence of symptoms before surgery, length of stay, or postoperative morbidity or mortality between the left and right groups were found. A majority of the surgeons surveyed indicated they do consider the relationship of side of the carotid disease to the patient's dominant side. The significant difference in the performance of left CE more often than right has not been previously reported. This may reflect willingness by surgeons to intervene more frequently in carotid disease on the side supplying the dominant hemisphere. A prospective CE outcome study that identifies the side of CE and the patient's dominant side is needed for further exploration of this issue.

Objective: To determine whether the rates of death and complications of carotid endarterectomy (CE) were different in the octogenarian population than in patients younger than age 80., Summary Background Data: The utility of CE depends on the ability of the surgeon and hospital to attain low rates of death and complications, including all subgroups of the patient population. In the past 30 years, the number of people age 85 and older has increased 274%., Methods: Detailed chart review was carried out on all CE procedures done from 1979 through 1998. Descriptive demographic data, risk factors, surgical details, length of stay, deaths, and complications were recorded., Results: A total of 2,398 CEs were performed in 1,970 patients; 2,180 procedures were performed in 1,783 patients younger than 80, and 218 CEs were performed in 187 patients age 80 and older. Sixty-five percent of the octogenarians and 67% of patients younger than age 80 had neurologic symptoms. Among asymptomatic patients, 89% had stenosis of 75% or more. There were 62 strokes in the 2,180 procedures in the younger group, for a stroke rate of 2.8%, and 7 strokes in the 218 procedures in the older group, for a stroke rate of 3.2%. The death rates were 0.9% for the octogenarians and 1.4% for the younger group., Conclusions: Carotid endarterectomy can be safely performed in a community hospital in patients age 80 and older. Outcomes in octogenarians were not significantly different than those of younger patients and were within the range required for CE to be considered beneficial in the prevention of stroke.

Background: We assessed whether the increase in performance of laparoscopic cholecystectomy has affected patients aged 80 and older and if outcomes of a laparoscopic approach in this population would show improvement over those for open surgery., Methods: We analyzed an 11-state discharge database obtained from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project. Release 1 contains a 20% sample of United States hospitals for the period 1988 to 1992. Diagnosis-related group (DRG) codes 197 and 198 were searched, and demographics, type of surgery, and outcome measures were analyzed., Results: In 5 years, 350,451 patients underwent cholecystectomy with the DRG codes listed. Of those, 18,500 patients were aged 80 to 105. The total number of cholecystectomies increased each year. Performance of laparoscopic cholecystectomy rose rapidly and that of open cholecystectomy decreased. Overall mortality with laparoscopic cholecystectomy was 1.8%, was lower than that of open cholecystectomy, was lower in women, and decreased with time., Conclusions: Patients aged 80 and older have participated in the increased performance of cholecystectomy and the switch to laparoscopic cholecystectomy. This has a low mortality, low length of stay, and higher proportion of patients being discharged to home compared with patients having open cholecystectomy.

Background: This study examined trends in breast conservation surgery (BCS) at our hospital and factors associated with BCS., Methods: We retrospectively reviewed breast cancer surgeries in patients eligible for BCS (size <4 cm, N0, N1) from 1990 through 1996 (n = 634). We calculated the yearly prevalence of BCS and used multiple logistic regression (MLR) to determine tumor, patient, and surgeon factors associated with BCS., Results: BCS increased from 17% in 1990 to 41% in 1996. Women with T1a and T1b tumors were 3.8 and 2.0 times, respectively, as likely to have BCS compared with those who had T2 tumors. Other factors associated with BCS included nonpalpable tumors, age <50, Medicare, Medicaid, or self-pay patients, and women whose surgeons graduated since 1961, with odds ratios of 1.8, 1.9, 2.4, and 2.3, respectively., Conclusion: Women with small, nonpalpable tumors, age <50, without private insurance, operated on by younger surgeons were more likely to receive BCS.

Performance of laparoscopic cholecystectomy (LC) is increasing, and patients age 80 and over comprise an increasingly larger proportion of the LC population. This study documents that the increase is accompanied by safe outcome in this patient population. However, the evidence also suggests that cholelithiasis appears to have been a neglected condition in this age group. The prevalence of nonelective procedures, the conversion rate to an open operation, more intraoperative complications, and the percentage having evidence of common bile duct stone passage all support this assertion. With the technology of LC, we are now appropriately addressing the problem with a treatment that allows less surgical trauma to the patient and shorter recovery time. Same-day LC surgery for the octogenarian appears to be very safe and would justify a decision to perform earlier LC in these patients. Surgery done before the appearance of comorbid conditions that increase the surgical and anesthetic risks may result in improved outcomes for the elderly at lower cost. Even when necessary in the already hospitalized patient, LC can be accomplished with morbidity and mortality comparable to those of elective abdominal procedures in younger populations.

Background: The purpose of this paper was to determine whether Medicare reimbursement for hip fracture reaches cost in geriatric patients., Methods: We conducted a retrospective review using the hospital trauma registry. Demographics, operations, length of stay, clinical outcome, discharge disposition, hospital charges, and hospital costs were reviewed and compared with diagnosis-related group (DRG) reimbursement., Results: The study included 153 Medicare patients. Mortality was 3.9%, 71% were discharged to a nursing home or rehabilitation unit, and 25% went directly home. DRG reimbursement constituted 58% of charges. Compared with costs, the DRG amount represented a mean loss of nearly $1,000 per patient., Conclusions: DRG reimbursement undercompensates the community hospital trauma center for treating a common malady among the geriatric population. A population shift toward the elderly, decreasing Medicare remuneration, and the advance of managed care will make correct identification and control of costs extremely important for the hospital caring for hip fractures in the geriatric population.

Background: For more than 40 years carotid endarterectomy (CE) has been used in the treatment of extracranial carotid disease for the prevention of stroke. Recent prospective clinical trials have confirmed the benefit of CE for both symptomatic and asymptomatic patients. Our purpose was to examine statewide trends in the numbers of CE over a 6-year time period and to evaluate outcomes., Methods: Using data from the North Carolina Medical Database Commission (NCMDC) all CE procedures from 1988 to 1993 were identified. Numbers of CE were compared with the population and hospital admissions. Variables of length of stay, hospital charges, discharge disposition, and occurrence of stroke and death were analyzed., Results: A total of 11,973 CE were performed in 6 years. Compared by admissions, population, and the proportion of elderly, the number of CE increased yearly. The stroke rate was 1.7% and the death rate 1.2% for an overall in-hospital stroke plus mortality rate of only 2.7%., Conclusions: From a diverse group of hospitals and a large number of surgeons and patients, this hospital-based study documents the acceptance and safety of CE in the treatment of extracranial carotid disease.

Objective: Clinical pathways now highlight both observation and operation as acceptable initial therapeutic options for the management of patients with splenic injury. The purpose of this study was to evaluate treatment trends for splenic injury in all North Carolina trauma centers over a 6-year period., Methods: Splenic injuries in adults over a 6-year period (January 1988-December 1993) were identified in the North Carolina Trauma Registry using ICD-9-CM codes. Patients were divided into four groups by method of management: 1) no spleen operation, 2) splenectomy, 3) definitive splenorrhaphy, and 4) splenorrhaphy failure followed by splenectomy. The authors examined age, mechanism of injury, admitting blood pressure, and severity of injury by trauma score and injury severity score., Summary Background Data: Comparisons were made between adult (17-64 years of age) and geriatric (older than 65 years of age) patients and between patients with blunt and penetrating injury. Resource utilization (length of stay, hospital charges) and outcome (mortality) were compared., Results: One thousand two hundred fifty-five patients were identified with splenic injury. Rate of splenic preservation increased over time and was achieved in more than 50% of patients through nonoperative management (40%) and splenorrhaphy (12%). Splenorrhaphy was not used commonly in either blunt or penetrating injury. Overall mortality was 13%. Geriatric patients had a higher mortality and resource utilization regardless of their mechanism of injury or method of management., Conclusions: Nonoperative management represents the prevailing method of splenic preservation in both the adult and geriatric population in North Carolina trauma center hospitals. Satisfactory outcomes and economic advantages accompany nonoperative management in this adult population.

Recognition of the important role of the spleen within the immune system has prompted surgeons to regularly consider splenic preservation. We studied our experience at a Level II trauma center to determine whether this trend is reflected in our management. We reviewed 81 adult blunt trauma patients with splenic injury admitted between January 1988 and December 1993. We examined age, race, and clinical data including mechanism of injury, trauma and injury severity scores, organ injury scale (OIS) grade, admitting blood pressure, operations, length of stay, hospital charges, and outcome. Thirty-nine patients underwent immediate splenectomy. Nonoperative treatment was successful in 31 of 37 patients (83.7%). Mean OIS grade (American Association for the Surgery of Trauma) was significantly different between patients treated nonoperatively (1.6 +/- 0.9) and patients treated with immediate splenectomy (3.9 +/- 1.1), (P = <0.001). American Association for the Surgery of Trauma OIS grade correlated well between CT classification and classification at operation (r = 0.7, P = 0.0001) but did not predict success in nonoperative management. Hemodynamic stability, injury severity, and abdominal CT scan findings determine choice of therapy. Splenorrhaphy is frequently discussed but infrequently performed. Splenectomy remains the most commonly performed operation for splenic injury in adults with blunt splenic trauma. Nonoperative management is the most common method of splenic salvage at the Level II community hospital trauma center.

Background: To assess the use and usefulness of fine-needle aspiration cytologic biopsy (FNAB) of the thyroid in our hospital., Methods: All cytology slides and charts of patients who had FNAB of the thyroid done in our hospital in 1993 were reviewed. Charts of all patients having thyroid surgery in our hospital in 1993 were reviewed to determine the pathological diagnosis and whether FNAB had been performed preoperatively. Finally, we reviewed all consecutive thyroid surgery cases for an 8-year period, and we calculated the yearly percentage of malignancy., Results: Fifty-five FNAB were done in 53 patients. In 21 patients the FNAB gave indication for thyroid surgery, yet surgery was done in only 12 (57.1%). Forty-two patients had surgery for a thyroid nodule, but only 20 patients (47.6%) had a preoperative FNAB. There were 3 malignancies among the 20; 2 were correctly predicted by FNAB. The FNAB was correct in 18 of 20. In all, 378 thyroid operations were done from 1987 to 1994. The yearly proportion of thyroid malignancy ranged from 11% to 29%, but showed no change corresponding with increasing diagnostic sophistication., Conclusions: Fine-needle aspiration cytologic biopsy in the workup of patients with thyroid masses is strikingly underutilized in our institution. While accurate in 90% of cases where used, FNAB appears to play a minor role in the surgeon's decision regarding surgery. As a result of these findings, we developed a grading system for better communication of the FNAB report and a clinical guideline to improve the evaluation of patients with thyroid masses.

Background: Clinical studies have shown equivalent survival rates between breast-conserving surgery (BCS) and mastectomy in early breast cancer; however, rates for BCS remain low. The purpose of this study was to determine (a) the prevalence of BCS in a regional medical center, (b) clinicopathologic factors associated with BCS, and (c) patient perceptions of the treatment decision-making process., Methods: We retrospectively reviewed 251 consecutive breast cancer cases during January 1990-December 1991; 77 patients were ineligible for BCS because of unfavorable pathology. We then interviewed 118 of the 160 women available for interview., Results: BCS was performed in 31 of the eligible patients (18%). Multivariate analysis revealed that tumor size < 10 mm (p = 0.03) was the only significant predictive variable for BCS. Patient interviews revealed that 93% said their surgeon was the primary source of information regarding treatment options. Among 69% of the women whose surgeons reportedly recommended a particular option, 89% recommended mastectomy with 93% compliance, and 11% recommended BCS with 89% compliance. The BCS group more often obtained a second opinion (p = 0.04) and 60% said they made the decision themselves compared with only 37% of the mastectomy group (p = 0.05)., Conclusion: Limiting BCS to women whose tumor size is < 10 mm is too restrictive; this excludes a large number of women who are clinically eligible for BCS. The surgical decision-making process for early-stage breast cancer is very much surgeon-driven, with a high degree of patient compliance.

Objective: This study sought to determine if violence against women is accurately documented in the trauma registry, and if poor documentation in the medical record is associated with incorrect coding in the registry., Design: Retrospective cohort study., Materials and Methods: We identified women aged 15 to 49 in the trauma registry of a regional medical center who had unintentional and intentional injuries over three years, and retrospectively reviewed their medical records to verify registry coding., Measurements and Main Results: Of the 41 assault victims in the registry, 32 were verified by the medical record. Of the 87 unintentional injuries, only 28 were verified; 21 were assault victims according to the medical record, and for the remaining 38, the medical record was too vague to determine intentionality. Thus, the sensitivity of the trauma registry in documenting violence against women was only 57%. Injuries correctly coded in the registry had the details well documented in the medical record, whereas injuries incorrectly coded had poor documentation in the medical record., Conclusions: Violence against women often goes undocumented in hospital data systems.

The purpose of this study was to examine the financial impact of assault-related penetrating trauma. We specifically reviewed hospital charges and reimbursement data. Two hundred eleven patients were identified from our Trauma Registry in a 4-year period: 108 with firearm injuries and 103 with injuries related to cutting or piercing instruments. Assault-related penetrating injuries generated more than $2,000,000 in hospital charges. Sixty-seven percent of this amount was incurred by patients who had no source of third-party payment. Reimbursement covered only 30% of charges. There were no differences in demographics, procedures, or in insurance status, mean charges, and unpaid balances between patients directly admitted and those transferred from other hospitals. Financial losses incurred by community hospitals from the care of penetrating injuries are substantial, and must be borne by cost shifting or other strategies. No evidence of "dumping" was found among this group of patients. The specter of injury caused by intentional violence extends beyond urban trauma centers, and has a serious negative financial impact on community trauma centers.

The administration of oral contrast (OC) is widely recommended for computed tomography (CT) of the abdomen in patients with blunt trauma. The purpose of this study was to determine whether routine abdominal CT scans performed without OC were associated with diagnostic error in patients with blunt trauma. Four hundred ninety-two patients were identified from our Trauma Registry who had CT scans for the evaluation of blunt abdominal trauma between January 1988 and December 1991. Seventy-six percent (372) of the CT scans were interpreted as negative, and 24% (120) were considered positive. OC was used in 8 (1.6%) of 492 patients. Only 1 of 372 patients whose initial non-OC--enhanced scan was negative subsequently required surgery. There were 5 bowel injuries among the 42 patients who underwent an abdominal operation; in none would the use of OC have ensured the preoperative diagnosis. We found that the omission of OC did not represent a disadvantage to patients with blunt trauma undergoing a routine abdominal CT scan. Potential time delays and the hazards associated with the use of OC were minimized.

Objective: The purpose of this paper is to compare the hospital resources used by elderly, adult, and pediatric patients treated in hospitals reporting to the North Carolina Trauma Registry (NCTR)., Design: We analyzed data on all patients entered into the NCTR from 1 January 1988 to 31 December 1990., Setting: The NCTR is a statewide registry of all trauma patients admitted for at least 24 hours or dead on arrival at the eight Level I and II trauma center hospitals in North Carolina., Patients: The total number of patients included in the study was 21,214; elderly adults included those age 65 and older (n = 2808), adults included those 15 to 64 years old (n = 15,776), and pediatric patients included those 0 to 14 years old (n = 2630)., Main Outcome Measures: We examined hospital resources using three measures: overall length of hospital stay in days, intensive care unit (ICU) length of stay in days for those admitted to the ICU, and total hospital charges billed during the hospitalization., Results: Controlling for injury severity, we found that elderly adults had longer mean hospital and ICU lengths of stay and higher mean hospital charges than adults or children. Whereas only 22% of injuries to elderly adults were transportation-related, transportation injuries generated 38% of their hospital charges. Sixty-eight percent of their injuries were caused by falls, generating total hospital charges of $17.6 million, an average of 15 days in hospital stay and 9 days in ICU stay., Conclusion: A 10% reduction in both transportation injuries and falls among the elderly could save $3.5 million in this population over 3 years.

Interventricular septal defect following nonpenetrating trauma is a rare event. In a review of 207,548 autopsies, only 30 (0.01%) cases of traumatic ventricular septal defects were noted, and only 5 (0.002%) were isolated. We report an isolated interventricular septal defect following nonpenetrating trauma.

We compared the first year's experience in performing laparoscopic cholecystectomy in a university hospital and a community hospital to determine the impact of postgraduate surgical training on outcome. Laparoscopic cholecystectomy was attempted on 446 patients. The conversion rate to open cholecystectomy was 8.3% and did not differ between institutions. Surgical house staff performed 43% of the cases at the university hospital compared with 8% at the community hospital. The greater use of laser and cholangiograms resulted in significantly longer mean operative time at the university hospital (141 +/- 26 min) than at the community hospital (114 +/- 52 min). The overall complication rate did not differ significantly (p = 0.15). Complications included common duct injury (three cases), bile leak (five cases), bleeding or hematoma (six cases), epigastric artery hematoma (one case), and death (one case). Operative inexperience during this first year may be a major determinant for the complication rates at both hospitals. It is too early to determine the impact of graduate surgical education on complications. Intense education and supervised instruction is requisite to minimizing the morbidity associated with laparoscopic cholecystectomy regardless of whether it is performed at a university or community hospital.

A 51-year-old woman with known dextrocardia presented with left-sided abdominal pain and symptoms consistent with biliary colic and cholelithiasis. Abdominal ultrasound confirmed the diagnosis of gallstones, as well as situs inversus with the liver and gallbladder on the left side and the spleen on the right. Laparoscopic cholecystectomy was performed without incident. The procedure was uncomplicated except for being the mirror image of that done with the gallbladder in the normal location. Cholelithiasis occurring with situs inversus is rare and may present a diagnostic problem. The extrahepatic anatomy of the biliary and venous system is the mirror image of the right sided liver. Historic and genetic aspects of situs inversus, as well as current theories regarding its etiology are presented. Situs inversus totalis does not appear to be a contraindication to laparoscopic treatment of cholelithiasis.

To determine differences in outcome between unilateral and staged bilateral carotid endarterectomies, we reviewed 850 carotid endarterectomies done by 14 surgeons in a community hospital. Results of 528 unilateral procedures were compared with those of 161 bilateral procedures. Data were abstracted from records for an 11-year period. Twelve of the patients in the unilateral group had nonfatal strokes, and 14 died within 30 days of surgery (stroke + death rate, 4.9%). There were no nonfatal strokes among patients in the bilateral group, and nine died (stroke + death rate, 5.6%). Seven of 14 deaths in the unilateral group and six of nine deaths in the bilateral group were due to neurologic events. In the bilateral group, death was associated with postoperative hypertension and a short intersurgical interval. The stroke + death rate was not significantly different between unilateral and bilateral procedures and compared favorably with North American Symptomatic Carotid Endarterectomy Trial guidelines and other published reports. Staged bilateral carotid endarterectomy can be safely performed in a community hospital.

Thoracic Electrical Bioimpedance (TEB) is a method for measuring cardiac performance which is noninvasive, continuous, has minimal technical requirements, and no patient risk. We used a commercially available TEB device to measure cardiac output in patients with thermodilution catheters in place. We compared the cardiac output measurements for the two modalities. We also compared the average hospital cost for initial cardiac assessment using the two techniques. The mean difference between the two cardiac output measurements was small (0.23 +/- 0.56) and not affected by the magnitude of the cardiac output readings. There was a strong correlation between COTD and COTEB (r = 0.91) and the regression slope was 0.91 with a Y intercept of 0.76. Cost analysis demonstrated that the use of TEB was approximately $600 less than thermodilution. Thoracic electrical bioimpedance measurement of cardiac output may offer a valuable alternative to the invasive measurement of the thermodilution catheter.

An impacted gallstone in the cystic duct with subsequent inflammation and edema resulting in extrinsic compression of the common bile or common hepatic duct with obstructive jaundice is known as Mirizzi's syndrome. An uncommon complication of cholelithiasis, Mirizzi's syndrome should be included in the differential diagnosis of any patient who has extrahepatic biliary obstruction. We present a case of a patient who underwent open rather than coelioscopic cholecystectomy based upon the preoperative diagnosis of Mirizzi's syndrome. A multidisciplinary approach to such patients facilitates the decision between open and endoscopic cholecystectomy. Mirizzi's syndrome may represent a contraindication to endoscopic cholecystectomy.

Sepsis after splenectomy is a lifelong risk, and patients who have had splenectomy should be educated about this risk. This study examines patient knowledge after splenectomy. We reviewed hospital records of 118 patients who had splenectomies performed between 1982 and 1988 at New Hanover Memorial Hospital. Twenty-four patients have died since their surgery; one death was suspected to be due to postsplenectomy sepsis. Of the 89 patients alive and eligible for follow-up, we were able to query 63. Only 16% were aware of any health precautions. After prompting, patient awareness improved to 40%. We also surveyed 11 of the 14 surgeons who performed the splenectomies. They indicated that they always discuss with their patients the immunologic consequences of spleen removal and the increased risks of infection, although they do not always recommend pneumococcal vaccine. We conclude that splenectomy patients have a low level of knowledge about postsplenectomy infection risks and precautions. We developed an educational pamphlet to aid the surgeon in patient education.

We compared the prevalence of stroke and death in 133 patients aged 75 and older in whom 170 carotid endarterectomies were performed with that in 501 patients less than age 75 in whom 640 carotid endarterectomies were performed. There were three strokes (2%) in patients aged 75 and older and nine strokes (1%) in younger patients (p = 0.7). There were 8 deaths (5%) in patients aged 75 and older and 14 deaths (2%) in younger patients (p = 0.1). After controlling for the possible confounding effects of diabetes, prior stroke, history of angina, prior carotid artery disease, previous vascular surgery, history of myocardial infarction, preoperative hypertension requiring medication, and female gender, a logistic regression model showed that patients aged 75 and older were no more likely to have a stroke or death than patients under age 75. We conclude that age alone is not a contraindication to the safe performance of carotid endarterectomy in the community hospital.

While controversy continues over the exact pathophysiology of and optimal therapy for phlegmasia cerulea dolens, increasing evidence favors the role of elevated interstitial pressure in the generation of extremity ischemia. We report the use of intramuscular pressure measurements in the assessment of a patient suffering massive venous occlusion of one leg. Significant elevations in pressure were found in association with symptomatic ischemia. Successful thrombectomy restored blood flow, relieved symptoms, and produced an immediate decrease in intramuscular pressure. In this disorder, measurement of compartment pressures can be useful in assessing the severity of venous insufficiency and in monitoring the response to therapy.

We report a survivor of Campylobacter fetus septicemia from an infected abdominal aortic aneurysm who was successfully treated with an anatomic graft reconstruction and antibiotics. According to a survey of the English-language medical literature this was the fourth such patient successfully treated. C. fetus sepsis associated with an abdominal aortic aneurysm was first reported in 1971. The first patient to survive reconstruction of an aortic tube graft aneurysm infected with C. fetus was reported in 1983. Because the natural history of an aneurysm infected by C. fetus appears to be rapid progression to rupture, patients should be operated on promptly. All patients reported in the literature who were operated on before rupture survived. Survival was independent of the type of reconstruction. When the aneurysm ruptured all patients died. Whereas extraanatomic bypass is generally considered the procedure of choice for an infected abdominal aneurysm, the aneurysms of our patient and three other patients cited in the literature were reconstructed with anatomically placed prosthetic grafts. In the absence of other contraindications such as a grossly evident purulent infection, an abdominal aortic aneurysm infected by C. fetus may represent a subset of infected aneurysms that can be treated successfully with an anatomically placed prosthetic graft and antibiotics.

A cooperative clinical trial was conducted among 5 transplant centers in the western United States to determine the value of magnesium sulfate in intracellular electrolyte flush solutions for hypothermic, human kidney storage. Kidneys from alternate donors were flushed with either magnesium-free Euro-Collins' solution or magnesium-containing Collins' 2 solution. Donor and recipient ages, and mean preservation times were not significantly different between the 2 groups. There was a significantly lower dialysis requirement during the first week in the magnesium-containing Collins 2 group (33 per cent) versus the Euro-Collins group (54 per cent). Function rates and serum creatinine nadirs at 1 month were not significantly different. The beneficial effect of magnesium sulfate was more evident when preservation times exceeded 24 hours.

We have reported a gonococcal infection in a surgical incision made ten months before the onset of urethral discharge. Gonococcal wound infections may arise from direct contamination or possibly by blood-borne dissemination. Principles guiding therapy are similar to those for wound infections from other organisms, with attention to adequate drainage, removal of foreign body, appropriate antibiotics, and elimination of contributing sources of infection.

We herein report on a patient who was subjected to bilateral nephrectomy in the course of treating unilateral renal cell carcinoma. The patient has survived for 3 1/2 years free of tumor and has had normal renal function after a 4 antigen match cadaver kidney allograft.

More than 50% of patients with chronic renal failure will be suppressed in their cell-mediated immune response to 2,4-dinitrochlorobenzene (DNCB). This applies in renal failure attributable to juvenile onset diabetes as well as other types of end stage renal disease. Significantly better kidney survival of both living related and cadaver grafts is seen in diabetic patients who are non-responsive to DNCB. Twelve-month kidney survival for DNCB-negative patients receiving living related allografts is 71% compared with 25% for DNCB-positive patients. Twelve-month kidney survival in cadaver recipients is 39% in DNCB-negative compared with 9% for DNCB-positive patients. Successful second grafts were done in DNCB-negative diabetic patients, however, all second grafts in DNCB-positive patients failed in less than 3 months. DNCB skin test reactivity as a measure of cell-mediated response is a valuable predictor of immunological outcome of transplantation in patients whose renal disease results from juvenile onset diabetes. Patient survival in DNCB nonresponders is nearly twice that of DNCB responders. Differences in outcome following transplantation could not be accounted for by HLA disparity, transfusion history, or other variables known to effect transplant outcome. Kidney and patient survival in DNCB-positive diabetic patients receiving either cadaver or living related allografts is sufficiently low as to identify them as a subpopulation of renal failure patients who should be treated by dialysis, or selected for special protocols which might provide immunological manipulation prior to transplantation to improve their treatment outcome.
