Establishing a laparoscopic bariatric program in a safety net hospital.

BACKGROUND: Most laparoscopic bariatric programs are situated in a community- or university-based hospital. The authors have recently initiated a program at a safety net hospital. This investigation hypothesizes that a laparoscopic bariatric program can be established at a safety net hospital with good clinical and financial results. METHODS: A laparoscopic bariatric program was initiated December 2002 at a safety net hospital. The program included a dedicated operative suite, an operative team, a bariatric unit, and a clinical pathway. The data for all the patients who underwent laparoscopic gastric bypasses up to June 2003 were analyzed. The patients were analyzed by type of insurance: government-sponsored insurance (G) or commercial insurance (C). RESULTS: There were 104 patients during this period. Their mean age was 40 years (range, 18-63 years), and their mean body mass index was 48 (range, 38-62). The median length of hospital stay was 2 days (mean, 3.9 days). Hypertension and diabetes were resolved for more than 80% of the patients. The average percentage of excess body weight loss was 73% after 1 year. There were no significant clinical differences between payor groups. The payor mix was 31% G and 69% C. The mean collection rates for hospital charges were 10% for G versus 53% for C (p < 0.0001). CONCLUSIONS: A laparoscopic bariatric program can be established in a safety net hospital with good clinical results. Findings showed that 1-year weight loss and comorbidity improvement/resolution compares favorably with those of other programs. Despite the overall poor payor mix of many safety net hospitals, a bariatric program can be established and can attract a high rate of commercially insured patients.

Free fluid on abdominal computed tomography without solid organ injury after blunt abdominal injury does not mandate celiotomy.

BACKGROUND: Mandatory celiotomy has been proposed for all patients with unexplained free fluid on abdominal computed tomography (CT) scanning after blunt abdominal injury. This recommendation has been based upon retrospective data and concerns over the potential morbidity from the late diagnosis of blunt intestinal injury. This study examined the rate of intestinal injury in patients with free fluid on abdominal CT after blunt abdominal trauma. METHODS: This study was a multicenter prospective series of all patients with blunt abdominal trauma admitted to four level I trauma centers over 22 months. Data were collected concurrently at the time of patient enrollment and included demographics, injury severity score, findings on CT scan, and presence or absence of blunt intestinal injury. This database was specifically queried for those patients who had free fluid without solid organ injury. RESULTS: In all, 2,299 patients were evaluated. Free fluid was present in 265. Of these, 90 patients had isolated free fluid with only 7 having a blunt intestinal injury. Conversely, 91% of patients with free fluid did not. All patients with free fluid were observed for a mean of 8 days (95% confidence interval 6.1 to 10.4, range 1 to 131). There were no missed injuries. CONCLUSIONS: Free fluid on abdominal CT scan does not mandate celiotomy. Serial observation with the possible use of other adjunctive tests is recommended.

Does optimal timing for spine fracture fixation exist?

OBJECTIVE: To evaluate the effect of timing of spine fracture fixation on outcome in multiply injured patients. SUMMARY BACKGROUND DATA: There is little consensus regarding the optimal timing of spine fracture fixation after blunt trauma. Potential advantages of early fixation include earlier patient mobilization and fewer septic complications; disadvantages include compounded complications from associated injuries and inconvenience of surgical scheduling. METHODS: Patients with spine fractures from blunt trauma admitted to an urban level 1 trauma center during a 42-month period who required surgical spine fracture fixation were identified from the registry. Patients were analyzed according to timing of fixation, level of spine injury, and impact of associated injuries (measured by injury severity score). Early fixation was defined as within 3 days of injury, and late fixation was after 3 days. Outcomes analyzed were intensive care unit and hospital stay, ventilator days, pneumonia, survival, and hospital charges. RESULTS: Two hundred ninety-one patients had spine fracture fixation, 142 (49%) early and 149 (51%) late. Patients were clinically similar relative to age, admission blood pressure, injury severity score, and chest abbreviated injury scale score. The intensive care unit stay was shorter for patients with early fixation. The incidence of pneumonia was lower for patients with early fixation. Charges were lower for patients with early fixation. Patients were stratified by level of spine injury. There were 163 cervical (83 early, 80 late), 79 thoracic (30 early, 49 late), and 49 lumbar fractures (29 early, 20 late). There were no differences in injury severity between early and late groups for each fracture site. The most striking differences occurred in the thoracic fracture group. Early fixation was associated with a lower incidence of pneumonia, a shorter intensive care unit stay, fewer ventilator days, and lower charges. High-risk patients had lower pneumonia rates and less hospital resource utilization with early fixation. CONCLUSIONS: Early spine fracture fixation is safely performed in multiply injured patients. Early fixation is preferred in patients with thoracic spine fractures because it allows earlier mobilization and reduces the incidence of pneumonia. Although delaying fixation in the less severely injured may be convenient for scheduling, it increases hospital resource utilization and patient complications.

Failures of splenic nonoperative management: is the glass half empty or half full?

BACKGROUND: Published contraindications to nonoperative management (NOM) of blunt splenic injury (BSI) include age > or = 55, Glasgow Coma Scale score < or = 13, admission blood pressure < 100 mm Hg, major (grades 3-5) injuries, and large amounts of hemoperitoneum. Recently reported NOM rates approximate 60%, with failure rates of 10% to 15%. This study evaluated our failures of NOM for BSI relative to these clinical factors. METHODS: All patients with BSI at a Level I trauma center over a 46-month period ending September 1999 were reviewed. Failures of NOM included patients initially selected for NOM who subsequently required splenectomy/splenorrhaphy. RESULTS: Five hundred fifty-eight had BSI. Twenty-three percent (128) underwent emergent laparotomy for hemodynamic instability and 77% (430) were observed. The NOM failure rate was only 8%. Univariate analysis identified moderate to large hemoperitoneum (p < 0.03), grades 3 to 5 (p < 0.004), and age > or = 55 (p < 0.0006) as being significantly associated with failure. Multivariate analysis identified age > or = 55 and grades 3 to 5 injuries as independent predictors of failure. The highest failure rates (30-40%) occurred in patients age > or = 55 with major injury for moderate to large hemoperitoneum. Mortality rates for successful NOM were 12%, and 9% for failed NOM. CONCLUSION: Inclusion of all high-risk patients increased the NOM rate while maintaining a low failure rate. Although age > or = 55 and major BSI were independently associated with failure of NOM, approximately 80% of these high-risk patients were successfully managed nonoperatively. There was no increased mortality associated with failure. Although these factors may indeed predict failure, they do not necessarily contraindicate NOM.

ARDS after pulmonary contusion: accurate measurement of contusion volume identifies high-risk patients.

BACKGROUND: The pathophysiology of pulmonary contusion (PC) is poorly understood, and only minimal advances have been made in management of this entity over the past 20 years. Improvement in understanding of PC has been hindered by the fact that there has been no accurate way to quantitate the amount of pulmonary injury. With this project, we examine a method of accurately measuring degree of PC by quantifying contusion volume relative to pulmonary function and outcome. METHODS: Patients with PC from isolated chest trauma who had admission chest computed tomographic scan were identified from the registry of a Level I trauma center over a 1.5-year period. Subsequently, prospective data on all patients admitted to the intensive care unit with PC during a 5-month period were collected and added to the retrospective database. Using computer-generated three-dimensional reconstruction from admission chest computed tomographic scan, contusion volume was measured and expressed as a percentage of total lung volume. Admission pulmonary function variables (Pao2/FiO2, static compliance), injury descriptors (chest Abbreviated Injury Score, Injury Severity Score, injury distribution), and indicators of degree of shock (admission systolic blood pressure, admission base deficit) were documented. Outcomes included maximum positive end-expiratory pressure, ventilator days, pneumonia, and acute respiratory distress syndrome (ARDS). RESULTS: Forty-nine patients with PC (35 bilateral) were identified. The average severity of contusion was 18% (range, 5-55%). Patients were classified using contusion volume as severe PC (> or =20%, n = 17) and moderate PC (< 20%, n = 32). Injury Severity Score was similar in the severe and moderate groups (23.3 vs. 26.5, p = 0.33), as were admission Glasgow Coma Scale score (12 vs. 13, p = 0.30), admission blood pressure (131 vs. 129 mm Hg, p = 0.90), and admission Pao2/Fio2 (197 vs. 255, p = 0.14). However, there was a much higher rate of ARDS in the severe group as compared with the moderate group (82% vs. 22%, p < 0.001). There was a trend toward higher pneumonia rate in the severe group, with 50% of patients in the severe group developing pneumonia as compared with 28% in the moderate group (p = 0.20). CONCLUSION: Extent of contusion volumes measured using three-dimensional reconstruction allows identification of patients at high risk of pulmonary dysfunction as characterized by development of ARDS. This method of measurement may provide a useful tool for the further study of PC as well as for the identification of patients at high risk of complications at whom future advances in therapy may be directed.

Macrophage cyclooxygenase expression, immunosuppression, and cardiopulmonary dysfunction after blunt chest trauma.

BACKGROUND: Two series of experiments were performed in swine who received severe blunt chest trauma. The goals were to determine the time course of constitutive and inducible cyclooxygenase (COX) isozyme expression in pulmonary macrophages (Mphis), and to determine whether COX expression and cardiopulmonary dysfunction were altered when neutrophils (PMNs) were pharmacologically depleted with cyclophosphamide (CYC). METHODS: In series 1 (n = 17), anesthetized, mechanically ventilated swine were subjected to right chest trauma via captive bolt gun, hemorrhage, and a 60-minute shock period. In series 2 (n = 41), CYC (50 mg/kg intravenously) was administered 4 days before trauma, and the shock period was shortened to 30 minutes. In both series, hemodynamic support and supplemental oxygen were provided for an additional 60 to 90 minutes after shock. Mphis were isolated from serial bilateral bronchoalveolar lavages (BALs) and COX protein expression was measured with Western blots. RESULTS: In series 1, death occurred in 11 of 17. In survivors, Mphi COX-1 peaked at > 100 times baseline in both right BAL and left BAL by 60 minutes (before resuscitation). Changes in Mphi COX-2 were minimal. In series 2, before trauma, CYC (n = 16) reduced circulating and BAL PMNs by > 90% relative to control (n = 25, both p < 0.05) with no complicating side effects. After trauma, death occurred in 11 of 25 controls versus 9 of 16 with CYC. In survivors, PaO2/FIO2 was < 250 and PaCO2 was 25% higher on constant minute ventilation, indicating mismatched ventilation/perfusion; both changes were reduced with CYC (p < 0.05). In controls, bilateral histologic damage included edema, alveolar hemorrhage, and interstitial infiltrates. These changes were reduced by one third with CYC (p = 0.08). Trauma-induced changes in BAL protein, BAL elastase, or Mphi COX expression were not lessened by CYC. CONCLUSION: After unilateral chest trauma, Mphi COX-1, not COX-2, is induced bilaterally and before fluid resuscitation; CYC prevented PMN infiltration and attenuated structural and functional changes after resuscitation, which suggests that PMNs have a role in the pathogenic mechanism of secondary lung injury; Mphi COX expression and other injury markers were not altered by CYC; and since Mphis continued to express proinflammatory COX protein even after pretreatment with a powerful nonspecific immunosuppressant, and since there is residual alveolar capillary damage even in the absence of PMNs, it is logical to conclude that no single cell type or mediator is a practical therapeutic target and that novel resuscitation strategies must address multiple elements in the inflammatory cascade.

Blunt cerebrovascular injuries: diagnosis and treatment.

BACKGROUND: Blunt cerebrovascular injuries (BCVIs), once thought to be rare, have been recognized with increasing frequency in recent years. An incidence of 0.33% for carotid artery injury (CAI) was noted from our institution, with 24% stroke-related mortality. Vertebral artery injury (VAI) has been thought both rare and of questionable significance. Incidence, associated injury patterns, and outcomes were examined during a period of aggressive screening (four-vessel angiography). METHODS: Patients with BCVI were identified from the registry of a Level I trauma center over a 5-year period (1995-1999). RESULTS: One hundred thirty-nine BCVIs were identified in 96 patients: 75 were CAIs (14 bilateral), 64 were VAIs (14 bilateral), and 15 patients had both CAI and VAI. The incidence of CAI was 0.5% of all blunt trauma admissions, significantly higher than our earlier experience (p < 0.0002), whereas that for VAI was 0.4%. Thirty-four percent of CAIs were diagnosed because of ischemic changes and 38% because of injury pattern (neck, Horner syndrome, basilar skull fracture); only 12% of VAIs were diagnosed because of posterior circulation ischemia, with 64% because of injury pattern (cervical spine, soft tissue, facial fracture). Stroke-related mortality for CAI was 13%, and that for VAI was 4%. Forty-three of the 75 CAIs were treated (anticoagulation/antiplatelet) before development of ischemia. Thirty-nine of the 50 VAI patients were treated before development of ischemia. Stroke rate for CAI was 31% (hemiplegia/hemiparesis) and for VAI was 14% (brain stem dysfunction). Stroke rate for treated vessels (heparin, antiplatelet therapy) with CAI was 6.8% compared with 64% in untreated vessels (p < 0.001). Treated patients with VAI had a stroke rate of 2.6%, whereas untreated patients developed stroke 54% of the time. CONCLUSION: Increased awareness and aggressive screening have resulted in significantly increased incidence of diagnosis of CAI, with associated lower stroke-related mortality. VAIs have been noted with similar incidence, and though the stroke rate is lower with VAI, stroke outcomes are generally catastrophic. Anticoagulation therapy is effective for both varieties of BCVI.

Noninvasive cardiac output by partial CO2 rebreathing after severe chest trauma.

BACKGROUND: In multiple trauma patients, early continuous cardiac output (CCO) monitoring is frequently desired but is difficult to routinely employ in most emergency departments because it requires invasive procedures. Recently, a noninvasive cardiac output (NICO) technique based on the Fick principle and partial CO2 rebreathing has shown promise under a variety of conditions. Since this method has not been tested after lung damage, we evaluated its utility in a clinically relevant model. METHODS: Anesthetized, ventilated swine (n = 11, 35-45 kg) received a unilateral blunt trauma via a captive bolt gun followed by a 25% hemorrhage. After 60 min of shock, crystalloid resuscitation was given as needed to maintain heart rate < 100 beats/min and mean arterial pressure > 70 mm Hg. Standard CCO by thermodilution (Baxter Vigilance, Irvine, CA) was compared with NICO (Novametrix Medical Systems Inc., Wallingford, CT) for 8 hr. RESULTS: The severity of the injury is reflected by seven deaths (average survival time = 4.25 hr). Trauma increased dead space ventilation (19%), airway resistance (30%), and lactate (3.2 mmol/L), and decreased dynamic compliance (48%) and Pao2/Fio2 (54%). In these extreme conditions, the time course and magnitude of change of CCO and NICO were superimposed. Bland-Altman analysis reveal a bias and precision of 0.01 +/- 0.69 liters/min. The linear relationship between individual CCO and NICO values was significant (p < 0.0001) and was described by the equation NICO = (0.74 +/- 0.1)CCO + (0.65 +/- 0.16 liters/min) but the correlation coefficient (r2 = 0.541) was relatively low. The cause for the low correlation could not be attributed to increased pulmonary shunt, venous desaturation, anemia, hypercapnia, increased dead space ventilation, or hyperlactacidemia. CONCLUSION: NICO correlated with thermodilution CCO, but underestimated this standard by 26% in extreme laboratory conditions of trauma-induced cardiopulmonary dysfunction; 95% of the NICO values fall within 1.38 liters/min of CCO; and with further improvements, NICO may be useful in multiple trauma patients requiring emergency intubation during initial assessment and workup.

Minimal aortic injury: a lesion associated with advancing diagnostic techniques.

BACKGROUND: With the increasing use of high-resolution diagnostic techniques, minimal aortic injuries (MAI) are being recognized more frequently. Recently, we have used nonoperative therapy as definitive treatment for patients with MAI. The current study examines our institutional experience with these patients from July 1994 to June 2000. METHODS: All patients suspected of blunt aortic injury (BAI) by screening helical CT (HCT) underwent confirmatory aortography with or without intravascular ultrasound (IVUS). MAI was defined as a small (<1 cm) intimal flap with minimal to no periaortic hematoma. RESULTS: Of the 15,000 patients evaluated by screening HCT, 198 (1.3%) were suspected of having BAI. BAI was confirmed in 87 (44%), and 9 (10%) of these had MAI. The initial aortogram was considered normal in five of the MAI patients. The correct diagnosis was made by IVUS (four patients), and video angiography (one patient). One MAI patient had surgery, and two (22%) died of causes not related to the aortic injury. Follow-up studies were done on the six MAI patients that were discharged. In two, the flap had completely resolved, and in one it remained stable. The remaining three patients formed small pseudoaneurysms. CONCLUSION: Ten percent of BAI diagnosed with high resolution techniques have MAI. These intimal injuries heal spontaneously and hence may be managed nonoperatively. However, the long-term natural history of these injuries is not known, and hence caution should be exercised in using this form of treatment.

Combination therapy that targets secondary pulmonary changes after abdominal trauma.

After abdominal trauma, the lung is susceptible to secondary injury caused by acute neutrophil (PMN) sequestration and alveolar capillary membrane disruption. Adenosine is an endogenous anti-inflammatory metabolite that decreases PMN activation. AICAR ([5-amino-1-[beta-D-ribofuranosyl]imidazole-4-carboxamide]riboside) is the prototype of a novel class of anti-inflammatory drugs that increase endogenous adenosine. After trauma, AICAR administration has been shown to decrease secondary lung injury in models of hemorrhagic shock with delayed lipopolysaccharide challenge and pulmonary contusion. However, early suppression of PMN activation could worsen outcomes after penetrating abdominal trauma. We hypothesized that, after penetrating abdominal trauma, the ideal resuscitation strategy would involve early, short-lived suppression of PMN activation to minimize secondary lung injury, followed by later enhancement of PMN chemotaxis and phagocytosis [using granulocyte colony-stimulating factor (G-CSF)] to lessen late septic complications. G-CSF has not been shown to potentiate PMN mediated pulmonary reperfusion injury. Swine were subjected to cecal ligation/incision and hemorrhagic shock (trauma), followed by resuscitation with shed blood, crystalloid, and either G-CSF, a combination of G-CSF and AICAR, or 0.9% normal saline. At 72 h, bronchoalveolar lavage (BAL) leukocyte counts and protein concentration were determined, and lung tissue analysed for myeloperoxidase (MPO, a measure of PMN infiltration) and microscopic pathology. Analysis of BALs revealed a significant increase protein concentrations and in white blood cell and PMN infiltration (P< 0.05) following trauma. These acute changes were not exacerbated by G-CSF, but were reversed by combined AICAR + G-CSF, which implicates a physiologic role for adenosine. This suggests that combination therapy may have beneficial effects on the lung after trauma.

Identification of early predictors for post-traumatic pneumonia.

We demonstrated that the standard clinical criteria of fever, leukocytosis, purulent sputum, and infiltrate on chest radiograph are nonspecific for the diagnosis of post-traumatic pneumonia, and only approximately 50 per cent of patients with these conditions have pneumonia. Quantitative cultures of bronchoalveolar lavage effluent will differentiate pneumonia (requiring antibiotic therapy) from systemic inflammatory response syndrome (not requiring antibiotics). Early identification of patients at risk for pneumonia can target populations for clinical research. Because risk factors for pneumonia when diagnosed by quantitative cultures have not been defined we reviewed our recent experience to identify variables predictive of pneumonia. Patients over a 22-month period who survived > 48 hours were identified from the trauma registry. Pneumonia was defined as growth of > or = 10(5) organisms per milliliter in the bronchoalveolar lavage effluent. Risk factors evaluated included injury severity and severity of shock. There were 7503 patients (75% with blunt and 25% with penetrating injuries). The incidence of pneumonia was 6 per cent (7% of patients with blunt and 2% of patients with penetrating injuries). Logistic regression analysis identified age; Glasgow Coma Scale score; Injury Severity Score; transfusion requirements during resuscitation; spinal cord injury; chest injury severity; and emergent femur fixation, craniotomy, and laparotomy as being independent predictors of pneumonia. We conclude that multiple risk factors, which are all able to be determined early after injury, are predictive of post-traumatic pneumonia. Prompt identification of this high-risk group of patients allows prognostic considerations relative to patient management schemes and targets populations for prophylactic measures or immunomodulation.

Blunt renal artery injury: incidence, diagnosis, and management.

Renal artery injury is a rare complication of blunt abdominal trauma. Increasing use of CT scans to evaluate blunt abdominal trauma identifies more blunt renal artery injuries (BRAIs) that may have otherwise been missed. We identified patients with BRAI to examine the incidence and to evaluate the current diagnosis and management strategies. Patients admitted from 1986 to 2000 at a regional Level I trauma center sustaining BRAI were evaluated. Patients undergoing revascularization or nonoperative management were followed for renovascular hypertension. Twenty-eight patients with BRAI were identified out of 36,938 blunt trauma admissions between 1986 and 2000 (incidence 0.08%). Most renal artery injuries were diagnosed by CT scans (93%) with seven confirmatory angiograms. Nine patients had nephrectomy (one bilateral), and three patients with unilateral injuries were revascularized. Sixteen were managed nonoperatively including one patient who had endovascular stent placement. Three patients died from shock and sepsis. Follow-up for all patients ranged from one month to 8 years. Two patients developed hypertension: one who was revascularized (33%) and one was managed nonoperatively (6%). The frequency of diagnosis of BRAI is increasing because of the increased use of CT. Nonoperative management of unilateral injuries can be successful with a 6 per cent risk for developing renovascular hypertension. The role of endovascular stenting is promising, and further study is necessary.

Stress ulceration requiring definitive surgery after severe trauma.

Despite antiulcer prophylaxis 19 severely injured patients at our institution developed stress ulceration (SU) between 1989 and 1999 requiring surgery for perforation (n = 4) or bleeding (n = 15). A herald bleed (HB) 10.7 +/- 1.2 days after admission, 7.2 +/- 1.2 days before definitive operative therapy, and requiring 7.1 +/- 0.9 units of blood occurred in 93 per cent of patients operated on for bleeding. Bleeding preceded perforation in one patient. Central nervous system damage was part of the injury pattern in 68 per cent of the patients including spinal cord (42%), severe head injury (16%), or both (10%). Forty-two per cent had acalculous cholecystitis found at surgery. Eight patients had vagotomy and antrectomy (VA), and 11 patients had vagotomy and pyloroplasty (VP). VA required more time than VP (255 +/- 41 vs 158 +/- 13 minutes; P = 0.02). One patient (12.5%) rebled after VA versus two (18%) after VP; one patient in each group required reoperation. There was no difference in mortality, length of stay, or intensive care unit stay. A herald bleed preceded recurrent hemorrhage of SU by one week. Spinal cord or head injury increase the risk of SU. More than 40 per cent of patients with SU had acalculous cholecystitis found at operation. VA provides no benefit on rebleeding or reoperation over VP, so anatomical considerations and not rebleed rates should determine the surgical procedure.

Intermittent and continuous ceftazidime infusion for critically ill trauma patients.

BACKGROUND: The adequacy of intermittent and continuous infusion ceftazidime for the treatment of nosocomial pneumonia in critically ill trauma patients was assessed by analyzing ceftazidime pharmacokinetics in relation to the minimum inhibitory concentration (MIC) and treatment outcome. METHODS: Serial blood samples were obtained during ceftazidime therapy in 31 trauma patients. Ceftazidime pharmacokinetics were compared with that of previously studied healthy volunteers. Ceftazidime pharmacokinetics were analyzed according to the time above the MIC and treatment outcome. RESULTS: Critically ill trauma patients had a significantly increased volume of distribution and clearance (0.32 +/- 0.14 L/kg and 2.35 +/- 0.89 mL. min(-1). kg(-1), respectively) compared with healthy volunteers (0.21 +/- 0.03 and 1.58 +/- 0.23 mL. min(-1). kg(-1)). The time above the MIC was >/=92% of the dosing interval for all patients and treatment outcomes were similar between the two treatment groups. CONCLUSIONS: Ceftazidime pharmacokinetics are significantly altered in critically ill trauma patients. Both intermittent and continuous ceftazidime regimens were equally effective for the treatment of nosocomial pneumonia caused by less virulent bacteria.

Gastric outlet obstruction resulting from peptic ulcer disease requiring surgical intervention is infrequently associated with Helicobacter pylori infection.

BACKGROUND: Gastric outlet obstruction (GOO) secondary to peptic ulcer disease requiring therapeutic intervention remains a common problem. The incidence of Helicobacter pylori infection in this cohort has not been well defined. Pneumatic dilatation (PD) has been proposed as first-line therapy before surgical intervention. If H pylori infection in patients with GOO is infrequent, PD may not offer permanent control without the need for longterm antacid therapy. STUDY DESIGN: The purpose of this study was to examine the incidence of H pylori infection and surgical outcomes in patients undergoing resection for GOO. The records of all patients having resection (vagotomy and antrectomy) for benign disease from 1993 to 1998 for GOO at the University of Tennessee affiliated hospitals were reviewed retrospectively. Smoking history, NSAID use, weight loss, previous ulcer treatment, previous treatment for H pylori, and previous attempts at PD were among the factors examined. H pylori infection was documented by Steiner stain from either preoperative biopsy or, in most patients, final surgical specimens. Surgical complications and patient satisfaction were ascertained from inpatient records, postoperative clinical notes, and, where possible, followup telephone surveys. RESULTS: Twenty-four patients underwent surgical resection during the study period. There were 16 men and 8 women, with a mean age of 61 years (range 40 to 87 years). Weight loss was documented in 58% and averaged 27 lb. Five of 24 patients had previous attempts at PD, 3 of whom were H pylori negative. All five had further weight loss after these failed attempts. Of the 24 patients reviewed, only 8 (33%) were H pylori positive. There were no procedure-related deaths. Longterm clinical followup was possible in 16 of 24 patients, and all but one demonstrated dramatic clinical improvement by Visick score. CONCLUSIONS: We conclude the following: 1) In this cohort, H pylori infection was present in a minority; 2) previous attempts at PD were unsuccessful, which may be related to the H pylori-negative status of the patients; 3) mortality related to the operation was zero; and 4) patient satisfaction was positive by the Visick scale. Patients with H pylori-negative GOO resulting from peptic ulcer disease should be strongly considered for an early, definitive, acid-reducing surgical procedure.

Blunt hepatic injury: a paradigm shift from operative to nonoperative management in the 1990s.

OBJECTIVE: To analyze the outcome of hemodynamically stable patients with blunt hepatic injury managed nonoperatively, and to examine the impact of this approach on the outcome of all patients with blunt hepatic injury. SUMMARY BACKGROUND DATA: Until recently, operative management has been the standard for liver injury. A prospective trial from the authors' institution had shown that nonoperative management could safely be applied to hemodynamically stable patients with blunt hepatic injury. The present study reviewed the authors' institutional experience with blunt hepatic trauma since that trial and compared the results with prior institutional experience. METHODS: Six hundred sixty-one patients with blunt hepatic trauma during the 5-year period ending December 1998 were reviewed (NONOP2). The outcomes were compared with two previous studies from this institution: operative 1985 to 1990 (OP) and nonoperative 1993 to 1994 (NONOP1). RESULTS: All 168 OP patients were managed operatively. Twenty-four (18%) of 136 NONOP1 patients and 101 (15%) of the 661 NONOP2 patients required immediate exploration for hemodynamic instability. Forty-two (7%) patients failed nonoperative management; 20 were liver-related. Liver-related failures of nonoperative management were associated with higher-grade injuries and with larger amounts of hemoperitoneum on computed tomography scanning. Twenty-four-hour transfusions, abdominal infections, and hospital length of stay were all significantly lower in the NONOP1 and NONOP2 groups versus the OP cohort. The liver-related death rate was constant at 4% in the three cohorts over the three time periods. CONCLUSIONS: Although urgent surgery continues to be the standard for hemodynamically compromised patients with blunt hepatic trauma, there has been a paradigm shift in the management of hemodynamically stable patients. Approximately 85% of all patients with blunt hepatic trauma are stable. In this group, nonoperative management significantly improves outcomes over operative management in terms of decreased abdominal infections, decreased transfusions, and decreased lengths of hospital stay.
