Endostapler vs Endoloop closure of the appendiceal stump in laparoscopic appendectomy: Which has better outcomes?

BACKGROUND: In laparoscopic appendectomy (LA), closure of the appendiceal stump can be achieved using either an endostapler or endoloop. We compared outcome data from utilizing either technique. METHOD: Data was collected for all adult patients who underwent LA for appendicitis at a single institution over a 4-year period. Demographic data, complications, length of stay and hospital charges were compared between both groups. RESULTS: A total of 501 patients underwent LA in the 4-year period. There were no differences in age, gender or BMI. Additionally, there were no differences in procedure length, readmission rates, complication rates (including intra-abdominal abscess) or hospital charges. There was a slightly shorter length of stay in the endoloop closure group (1.22 days) vs endostapler (1.38 days), p = 0.002. CONCLUSION: Neither technique of appendiceal stump closure demonstrated a unique advantage. These findings may have relevance in low resource environments that may not have routine access to surgical staplers.

A comparison between the TEG 6s and TEG 5000 analyzers to assess coagulation in trauma patients.

BACKGROUND: Trauma-induced coagulopathy is a major driver of mortality following severe injury. Viscoelastic goal-directed resuscitation can reduce mortality after injury. The TEG 5000 system is widely used for viscoelastic testing. However, the TEG 6s system incorporates newer technology, with encouraging results in cardiovascular interventions. The purpose of this study was to validate the TEG 6s system for use in trauma patients. METHODS: Multicenter noninvasive observational study for method comparison conducted at 12 US Levels I and II trauma centers. Agreement between the TEG 6s and TEG 5000 systems was examined using citrated kaolin reaction time (CK.R), citrated functional fibrinogen maximum amplitude (CFF.MA), citrated kaolin percent clot lysis at 30 minutes (CK.LY30), citrated RapidTEG maximum amplitude (CRT.MA), and citrated kaolin maximum amplitude (CK.MA) parameters in adults meeting full or limited trauma team criteria. Blood was drawn ≤1 hour after admission. Assays were repeated in duplicate. Reliability (TEG 5000 vs. TEG 6s analyzers) and repeatability (interdevice comparison) was quantified. Linear regression was used to define the relationship between TEG 6s and TEG 5000 devices. RESULTS: A total of 475 patients were enrolled. The cohort was predominantly male (68.6%) with a median age of 49 years. Regression line slope estimates (ß) and linear correlation estimates (p) were as follows: CK.R (ß = 1.05, ρ = 0.9), CFF.MA (ß = 0.99, ρ = 0.95), CK.LY30 (ß = 1.01, ρ = 0.91), CRT.MA (TEG 6s) versus CK.MA (TEG 5000) (ß = 1.06, ρ = 0.86) as well as versus CRT.MA (TEG 5000) (ß = 0.93, ρ = 0.93), indicating strong reliability between the devices. Overall, within-device repeatability was better for TEG 6s versus TEG 5000, particularly for CFF.MA and CK.LY30. CONCLUSION: The TEG 6s device appears to be highly reliable for use in trauma patients, with close correlation to the TEG 5000 device and equivalent/improved within-device reliability. Given the potential advantages of using the TEG 6s device at the site of care, confirmation of agreement between the devices represents an important advance in diagnostic testing.

Management of traumatic subarachnoid hemorrhage by the trauma service: is repeat CT scanning and routine neurosurgical consultation necessary?

Subarachnoid hemorrhage (SAH) results frequently from traumatic brain injury (TBI). The standard management for these patients includes brief admission by the acute care surgery (trauma) service with neurological checks, neurosurgical consultation and repeat head CT within 24 hours to identify any progression or resolution. Recent studies have questioned the need for repeat CT imaging and specialty consultation in mild TBI. We reviewed patients with mild TBI specifically with isolated SAH to determine progression of the pathology and need for neurosurgical involvement. All patients with SAH secondary to mild TBI (Glasgow Coma Score (GCS) of 13-15) who presented over a 5-year period (January 2010 to December 2014) to a level I trauma center were identified from the trauma registry. Demographic data, initial CT findings, neurosurgical consultation, follow-up CT findings, Injury Severity Score (ISS), admission GCS and length of stay (LOS) were all obtained from the patient's charts. Patients with other traumatic brain lesions on the initial CT were excluded. There were 299 patients (male, 48.5%), mean age 60.9 and mean ISS 8. Average time between the first and second CT was 11.3 hours. In all, 267 (89.2%) patients had either no change or an improvement/resolution on follow-up CT scan. Only 26 patients (8.7%) had either worsening or new findings on CT. Eight patients did not have a second scan completed (2.6%). All patients had neurosurgical consultation. Patients with mild TBI with isolated SAH generally have low morbidity, short LOS and negligible mortality. Less than 10% of this population had worsening of their head injury on repeat CT scanning. Given the low acuity of these patients with SAH and tendency towards resolution without intervention, acute care surgeons can manage this specific group of patients with TBI without routine neurosurgical consultation. Repeat CT scanning continues to have utility as it may identify new lesions, deterioration or need for further management.

Laparoscopic cholecystectomy in the Acute Care Surgery model: risk factors for complications.

BACKGROUND: The Acute Care Surgery (ACS) model developed during the last decade fuses critical care, trauma, and emergency general surgery. ACS teams commonly perform laparoscopic cholecystectomy (LC) for acute biliary disease. This study reviewed LCs performed by an ACS service focusing on risk factors for complications in the emergent setting. METHODS: All patients who underwent LC on an ACS service during a 26-month period were identified. Demographic, perioperative, and complication data were collected and analyzed with Fisher's exact test, χ2 test, and Mann-Whitney U Test. RESULTS: During the study period, 547 patients (70.2% female, mean age 46.1±18.1, mean body mass index 32.4±7.8 kg/m2) had LC performed for various acute indications. Mean surgery time was 77.9±50.2 minutes, and 5.7% of cases were performed "after hours." Rate of conversion to open procedure was 6%. Complications seen included minor bile leaks (3.8%), infection (3.8%), retained gallstones (1.1%), organ injury (1.1%), major duct injury (0.9%), and postoperative bleeding (0.9%). Statistical analysis demonstrated significant relationships between conversion, length of surgery, age, gender, and intraoperative cholangiogram with various complications. No significant relationships were detected between complications and BMI, pregnancy, attending experience, and time of operation. DISCUSSION: Although several statistically significant relationships were identified between several risk factors and complications, these findings have limited clinical significance. Factors including attending years in practice and time of the operation were not associated with increased complications. ACS services are capable of performing a high volume of LCs for emergent indications with low complication and conversion rates.-Level of evidence:IV.

A comparison of prognosis calculators for geriatric trauma: A Prognostic Assessment of Life and Limitations After Trauma in the Elderly consortium study.

BACKGROUND: The nine-center Prognostic Assessment of Life and Limitations After Trauma in the Elderly consortium has validated the Geriatric Trauma Outcome Score (GTOS) as a prognosis calculator for injured elders. We compared GTOS' performance to that of the Trauma Injury Severity Score (TRISS) in a multicenter sample. METHODS: Three Prognostic Assessment of Life and Limitations After Trauma in the Elderly centers not submitting subjects to the GTOS validation study identified subjects aged 65 years to 102 years admitted from 2000 to 2013. GTOS was specified using the formula [GTOS = age + (Injury Severity Score [ISS] × 2.5) + 22 (if transfused packed red cells (PRC) at 24 hours)]. TRISS uses the Revised Trauma Score (RTS), dichotomizes age (<55 years = 0 and ≥55 years = 1), and was specified using the updated 1995 beta coefficients. TRISS Penetrating was specified as [TRISSP = -2.5355 + (0.9934 × RTS) + (-0.0651 × ISS) + (-1.1360 × Age)]. TRISS Blunt was specified as [TRISSB = -0.4499 + (0.8085 × RTS Total) + (-0.0835 × ISS) + (-1.7430 × Age)]. Each then became the sole predictor in a separate logistic regression model to estimate probability of mortality. Model performances were evaluated using misclassification rate, Brier score, and area under the curve. RESULTS: Demographics (mean + SD) of subjects with complete data (N = 10,894) were age, 78.3 years ± 8.1 years; ISS, 10.9 ± 8.4; RTS = 7.5 ± 1.1; mortality = 6.9%; blunt mechanism = 98.6%; 3.1 % of subjects received PRCs. The penetrating trauma subsample (n = 150) had a higher mortality rate of 20.0%. The misclassification rates for the models were GTOS, 0.065; TRISSB, 0.051; and TRISSP, 0.120. Brier scores were GTOS, 0.052; TRISSB, 0.041; and TRISSP, 0.084. The area under the curves were GTOS, 0.844; TRISSB, 0.889; and TRISSP, 0.897. CONCLUSION: GTOS and TRISS function similarly and accurately in predicting probability of death for injured elders. GTOS has the advantages of a single formula, fewer variables, and no reliance on data collected in the emergency room or by other observers. LEVEL OF EVIDENCE: Prognostic, level II.

Initial impact of the Affordable Care Act on an Ohio Level I trauma center.

BACKGROUND: Hospital financial pressures and inadequate reimbursement contribute to the closure of trauma centers. Uninsured patients contribute significantly to the burden of trauma center costs. The Affordable Care Act implemented changes in 2014 to provide health care coverage for all Americans. This study analyzes the impact of the recent health care changes on an Ohio Level I trauma center financials. METHODS: We conducted an analysis of trauma charges, reimbursement, and supplemental payments at an Ohio Level I trauma center. A 3-year trauma patient cohort (2012-2014) was selected and grouped by reimbursement source (Medicare, Medicaid, other government, commercial, and self-pay/charity). A total of 9,655 patients were reviewed. Data were collected with the Transition Systems Inc. accounting system and analyzed with IBM SPSS Statistics 22.0. RESULTS: For trauma cases, the percentage of self-pay/charity patients decreased during the 2012 to 2014 period (15.1%, 15%, to 6.4%, respectively), while the percentage of Medicaid decreased from 2012 to 2013 followed by a large increase in 2014 (15.4%, 13.9%, to 24.3%, respectively). The percentage of commercially insured patients decreased slightly from 2012 to 2014 (34.2%, 32.3%, to 30.7%, respectively). Uninsured charges decreased notably (approximately $22.5 million and $21 million for 2012-2013 to approximately $8.6 million in 2014). Medicaid charges decreased from 2012 to 2013, followed by a rebound in 2014 ($50.7 million in 2012 to $37.3 million in 2013 to $54.3 million in 2014). The percentage of total charges for self-pay/charity decreased (9.5%, 10.1%, to 4.1%). The percentage of total charges for Medicaid increased (21.4%, 18.0%, to 25.9%). Mean Medicaid reimbursement per patient decreased ($19,000, $14,000, to $13,000). Mean reimbursement per uninsured patient did not vary significantly among years. Total hospital supplemental payments (trauma and nontrauma combined) decreased ($47.6 million, $49 million, to $39.2 million). CONCLUSION: In the first year following the changes implemented by the Affordable Care Act, our hospital saw self-pay/charity charges decrease, Medicaid charges increase, and total hospital supplemental payments decrease. In addition, there was a small, yet noteworthy, downward trend in the number of commercially insured patients. Although more data collection and analysis are needed, this initial financial evaluation of a Level I trauma center following the Affordable Care Act provides insight into insurance trends.

Scheduling of advanced practice providers at Level 1 trauma centers.

BACKGROUND: Advanced practice providers (APPs) are essential to the provision of trauma care services, particularly in the wake of residency hour restrictions. Demand for these APPs fluctuates with cyclic patient arrivals; however, most trauma teams continue to staff APPs in a linear fashion. Failure to plan for variable arrivals may contribute to excessive patient wait times and emergency department overcrowding. This study used both qualitative and quantitative approaches to evaluate the impact of APP scheduling on patient wait time and to find schedules minimizing delays in reaching the needed care at the right time. METHODS: A retrospective observation of the availability of APPs and the flow of 2,249 trauma patients at a Level 1 trauma center, using both visual overlays and computer modeling, allowed us to evaluate the baseline condition, two what-if schedules, and two model-generated schedules minimizing patient time without any additional APP hours. RESULTS: A visual overlay of APP staffing on 2010 patient arrivals indicated substantial times of mismatch. Trauma managers considered adding an APP during weekday evenings that would have resulted in a 14.8% increase in APP hours and yielded a 27% reduction in patient wait times according to our model. An alternate schedule was developed and implemented in 2012 with a 10.5% increase in APP hours and yielding a 73% reduction in wait times. We also delineated two schedule options with 57% and 78% reductions in wait time and no increase in APP work hours. CONCLUSION: Evaluating alternate shift times and assignments using visual overlays and computer modeling can provide APP staffing solutions with up to 78% reduction in trauma patient wait time without additional APP labor. Knowing that care at the right time is crucial to arriving patients, making sure APP staffing is synchronized with arriving patients is something trauma center managers cannot ignore.

Successful placement of intracranial pressure monitors by trauma surgeons.

BACKGROUND: The Brain Trauma Foundation guidelines advocate for the use of intracranial pressure (ICP) monitoring following traumatic brain injury (TBI) in patients with a Glasgow Coma Scale (GCS) score of 8 or less and an abnormal computed tomographic scan finding. The absence of 24-hour in-house neurosurgery coverage can negatively impact timely monitor placement. We reviewed the safety profile of ICP monitor placement by trauma surgeons trained and credentialed in their insertion by neurosurgeons. METHODS: In 2005, the in-house trauma surgeons at a Level I trauma center were trained and credentialed in the placement of ICP parenchymal monitors by the neurosurgeons. We abstracted all TBI patients who had ICP monitors placed during a 6-year period. Demographic information, Injury Severity Score (ISS), outcome, and monitor placement by neurosurgery or trauma surgery were identified. Misplacement, hemorrhage, infections, malfunctions, and dislodgement were considered complications. Comparisons were performed by χ testing and Student's t tests. RESULTS: During the 6-year period, 410 ICP monitors were placed for TBI. The mean (SD) patient age was 40.9 (18.9) years, 73.7% were male, mean (SD) ISS was 28.3 (9.4), mean (SD) length of stay was 19 (16) days, and mortality was 36.1%. Motor vehicle collisions and falls were the most common mechanisms of injury (35.2% and 28.7%, respectively). The trauma surgeons placed 71.7 % of the ICP monitors and neurosurgeons for the remainder. The neurosurgeons placed most of their ICP monitors (71.8%) in the operating room during craniotomy. The overall complication rate was 2.4%. There was no significant difference in complications between the trauma surgeons and neurosurgeons (3% vs. 0.8%, p = 0.2951). CONCLUSION: After appropriate training, ICP monitors can be safely placed by trauma surgeons with minimal adverse effects. With current and expected specialty shortages, acute care surgeons can successfully adopt procedures such as ICP monitor placement with minimal complications.

Are flexion extension films necessary for cervical spine clearance in patients with neck pain after negative cervical CT scan?

BACKGROUND: There are variations in cervical spine (CS) clearance protocols in neurologically intact blunt trauma patients with negative radiological imaging but persistent neck pain. Current guidelines from the current Eastern Association for the Surgery of Trauma include options of maintaining the cervical collar or obtaining either magnetic resonance imaging (MRI) or flexion-extension films (FEF). We evaluated the utility of FEF in the current era of routine computerized tomography (CT) for imaging the CS in trauma. MATERIALS AND METHODS: All neurologically intact, awake, nonintoxicated patients who underwent FEF for persistent neck pain after negative CT scan of the CS at our level I trauma center over a 13-mo period were identified. Their charts were reviewed and demographic data obtained. RESULTS: There were 354 patients (58.5% male) with negative cervical CS CT scans who had FEF for residual neck pain. Incidental degenerative changes were seen in 37%--which did not affect their acute management. FEF were positive for possible ligamentous injury in 5 patients (1.4%). Two of these patients had negative magnetic resonance images and the other three had collars removed within 3 wk as the findings were ultimately determined to be degenerative. CONCLUSIONS: In the current era, where cervical CT has universally supplanted initial plain films, FEF appear to be of little value in the evaluation of persistent neck pain. Their use should be excluded from cervical spine clearance protocols in neurologically intact, awake patients.

Pilot evaluation of the short-term effect of driving simulation on novice adolescent drivers.

BACKGROUND: Despite widespread application in aviation and other fields, there has been limited use of computerized simulation in driver education. We prospectively studied a group of novice drivers subjected to comprehensive virtual driving simulation modules to identify the subsequent effects on their driving records. We hypothesized that participation in a simulation program would result in fewer offences and crashes. METHODS: Forty high school students who recently obtained their driver's license were randomized into driving simulator (DS) or control groups. The DS group went through 12 modules of driver education. Upon completion, driving records for all the individuals were collected at 6 months, 12 months, and 18 months, and comparisons were made. Statistical analysis was performed using χ², Fisher's exact tests, t tests, and Mann Whitney U-test where appropriate. RESULTS: Of the 20 subjects, 16 in the DS group completed all modules and were compared with 19 individuals in the control group. Sixty-nine percent in the DS group were male versus 89% in the control group. Mean age was similar in both groups. The average time to the first offense after completion in the DS group was 117 days versus 105 days in control group (p = 0.8). At 18 months, 18.8% in the DS group were involved in a driving incident compared with 47.4% in the control group (p = 0.1516). At 18 months, there were 4 incidents (0.25 incidents per person) in the DS group versus 17 incidents (0.89 incidents per person) in the control group. At 18 months, 6.2% in the DS were involved in accidents compared with 21.1% in the control group (p= 0.35). Speeding infractions occurred at 18 months in 12.5% in the DS group versus 26.3% in the control group (p = 0.4150). CONCLUSION: In this prospective pilot evaluation of computerized driving simulation, adolescents subjected to structured simulator training showed trends toward committing fewer offences and accidents. Larger studies examining the practical potential of driving simulation in novice drivers are needed. LEVEL OF EVIDENCE: Prognostic study, level III.

Complications arising from splenic artery embolization: a review of an 11-year experience.

BACKGROUND: Splenic artery embolization (SAE) is a staple adjunct in the management of blunt splenic trauma. We examined complications of SAE over an 11-year period. METHODS: Patients who underwent SAE were identified. Demographic data and the location of the SAE-proximal, distal, or combined-were noted. Major and minor complications were identified. RESULTS: Of 1,383 patients with blunt splenic trauma, 298 (21.5%) underwent operative management, and 1,085 (78.5%) underwent nonoperative management (NOM). SAE was performed in 8.1% of the NOM group. Major complications which occurred in 14% of patients, included splenic abscesses, infarction, cysts, and contrast-induced renal insufficiency. Three-fourths of patients with major complications underwent distal embolization. There were more complications in patients who underwent distal embolization (24% distal vs 6% proximal alone; P = .02). Minor complications, which occurred in 34% of patients, included left-sided pleural effusions, coil migration, and fever. CONCLUSIONS: SAE is a useful tool for managing splenic injuries. Major and minor complications can occur. Distal embolization is associated with more major complications.

The prevalence of incidental findings on abdominal computed tomography scans of trauma patients.

BACKGROUND: Abdominal computed tomography scanning (AbdCTS) is the standard of care in the evaluation of blunt trauma patients. The liberal use of AbdCTS coupled with advancing imaging technology often results in the detection of incidental findings. OBJECTIVES: We sought to characterize the incidence and prevalence of such findings, describe the lesions most frequently seen on AbdCTS performed on patients admitted to a Level I trauma center, and develop a plan for follow-up through our performance improvement process. METHODS: AbdCTS reports of all admissions to a Level I trauma center between January 2000 and December 2002 were reviewed. Incidental findings identified were classified into benign anatomic variants, benign pathologic lesions, and pathologic lesions requiring further work-up. RESULTS: A total of 3,113 patients were evaluated by AbdCTS during this time period. There were 1474 incidental findings in 1,103 patients. Seventy-five percent of patients with incidental lesions had no traumatic findings. Benign anatomic variants were present in 1.8%, benign pathologic findings in 27.5%, and pathologic findings requiring work-up in 6.1%. Congenital renal anomalies and duplicate inferior vena cava were the most common benign anatomical findings. Renal and hepatic cysts were the most frequent benign lesions and non-calcified pulmonary nodules and adrenal masses were the pathologic lesions most commonly seen. CONCLUSIONS: Incidental findings are seen in up to 35% of trauma AbdCTS. No concomitant traumatic injuries are present in up to 75% of these patients. Protocols for appropriate intervention or arrangements for follow-up care need to be incorporated into the care of the trauma patients.

The impact of splenic artery embolization on the management of splenic trauma: an 8-year review.

BACKGROUND: Splenic artery embolization (SAE) is an adjunct to nonoperative management (NOM) of splenic injuries. We reviewed our experience with SAE to identify its impact on splenic operations. METHODS: Patients admitted with splenic injuries over an 8-year period were identified and the initial method of management noted (simple observation, SAE, or splenic surgery). The first 4 years (period 1) during which SAE was introduced was compared with the latter 4 years (period 2) when it was used frequently. RESULTS: There were 304 patients in period 1 and 416 in period 2. NOM was initial management in 59.9% in period 1% and 60.1% in period 2 (P = 1.0) and failure rates were 5.3% versus 2.9%, respectively (P = .12). More SAE procedures were performed in period 2 -- 13.7% versus 4.9% (P < or = .001) -- and there was a reduction in the proportion of splenic operations -- 35.2% versus 26.2% (P <.01). CONCLUSIONS: SAE is associated with a reduction in splenic operations, although it did not alter the failure rate of NOM.

Is chest x-ray an adequate screening tool for the diagnosis of blunt thoracic aortic injury?

BACKGROUND: Blunt thoracic aortic injuries (BTAI) have a high mortality rate. For survivors, chest X-ray (CXR) findings are used to determine the need for further diagnostic testing with chest computerized tomography with angiography (CTA) or conventional angiography. We set to determine the adequacy of utilizing CXR alone as a screening tool for BTAI. METHODS: All patients diagnosed with BTAI at a level I trauma-center during a 7-year-period were identified. CXRs of these patients and those of a control group of blunt trauma patients with an injury severity score >15 were reviewed by four trauma surgeons blinded to the diagnosis. Based on each CXR viewed, the surgeons decided if they would have proceeded to chest CTA, angiography, or required no further studies to rule out BTAI. RESULTS: In the 7-year-period, 83 patients had BTAI. CXRs were available in 45 patients. The four surgeons viewed 96 CXRs including those of 51 controls. Based on the CXR appearance in patients with BTAI, the surgeons chose to proceed to chest CTA in 38 patients (84.4%), conventional aortography in two patients (4.4%), and no further testing in five patients (11.2%). A widened mediastinum (75%) and loss of the aorto-pulmonary window (40%) were the most frequent CXR abnormalities. Patients with BTAI were more likely to have an abnormal CXR-40 of 45 (88.8%) patients when compared with the controls-25 of 51 (49%)patients-p < 0.001. CONCLUSIONS: Although CXR is a sensitive screening modality, it failed to identify the possibility of BTAI in 11% of patients. The liberal use of chest CTA after high speed motor vehicle crashes is recommended to minimize the incidence of missed BTAI.

Management of acute appendicitis by an acute care surgery service: is operative intervention timely?

BACKGROUND: Trauma services are increasingly providing emergency surgery care by creating "acute care surgery" teams. We compared two periods at a Level I trauma center to determine if trauma service coverage would negatively impact timely management of acute appendicitis. STUDY DESIGN: All patients admitted through the emergency department of a Level I trauma center who underwent appendectomies between March 2005 and May 2006 (Trauma period) were identified. During this period, the trauma service covered most surgical emergencies. Comparison was made with the earlier 15-month period (Pretrauma). Emergency department to operating room (OR) time, procedure length, and negative appendectomy rates were obtained. RESULTS: In the Pretrauma period, 273 patients underwent appendectomy, compared with 279 in the Trauma period. Two-thirds (66%) of appendectomies in the Trauma period were performed by trauma surgeons. There was no difference in both periods with regard to mean emergency department to OR time (10.5 hours versus 9.9 hours; p = 0.4509), perforation rates (12% Pretrauma versus 7.5% Trauma; p = 0.1134), or negative appendectomy rates (17.9% Pretrauma versus 18.2% Trauma; p = 1.0). In the Trauma period, more appendectomies were completed laparoscopically (84.6% Trauma versus 66.6% Pretrauma; p < 0.0001), and mean OR time was shorter (57.4 minutes versus 67 minutes; p = 0.0006). CONCLUSIONS: In comparing two periods with and without the trauma service coverage of surgical emergencies, no difference was found in emergency department to OR time, perforation rates, or negative appendectomy rates in the management of acute appendicitis. There was a decrease in operative time and an increase in the proportion of laparoscopic appendectomies in the Trauma period. Trauma services can effectively incorporate emergency surgical coverage of procedures, such as appendectomies, without compromising timely intervention.

Laparoscopy in the contemporary management of acute appendicitis.

BACKGROUND: We sought to compare laparoscopic appendectomy (LA) with open appendectomy (OA) focusing on the negative appendectomy rate (NAR), emergency department (ED) to operating room (OR) time, procedure length, and histopathological correlation. METHODS: All appendectomies for appendicitis over a 6-year period at a single hospital were reviewed. Open and laparoscopic procedures were compared. RESULTS: There were 1,312 appendectomies (54.6% OA and 45.4% LA) Mean ED to OR time was as follows: LA 10.8 hours (standard deviation [SD] +/- 9.0) versus 9.8 hours (SD +/- 8.5) OA (P = .0333). Mean OR time was 61.2 minutes (SD +/- 29.1) LA versus 57.7 minutes (SD +/- 28) OA (P = .0293). NAR was 18.3%, LA 23.3% versus 14.0% OA (P < .0001). Postoperative correlation with histopathology was 86% for LA versus 92% OA (P = .0003). In the LA group, 9.9% with a "normal" appendix had appendicitis by histopathology. CONCLUSIONS: LA is associated with increased presentation to procedure time, operative time, and negative appendectomy rate. Removing a "normal" appendix during LA in the absence of alternate pathology is recommended.

Delayed closure of ventral abdominal hernias after severe trauma.

BACKGROUND: Primary closure after trauma celiotomies is not always accomplished. We reviewed our experience with delayed closure in trauma patients. METHODS: Prospective data were collected on patients who had damage-control celiotomy and were discharged with open abdomens. The time to closure, repair methods, and complication data also were compiled. RESULTS: In the 6-year period, 84 patients underwent damage-control celiotomy. Thirty-one patients died and 33 patients had early closure. Twenty patients had closure during a subsequent hospitalization (mean time to delayed closure, 193 days): 8 patients (40%) had component separation, 3 (15%) had component separation with mesh, 4 (20%) had mesh alone, and primary closure occurred in 5 (25%). Nine patients (45%) had complications such as wound and mesh infections, hernias, and fistulas. Repair before or after 6 months showed no statistically significant difference for the presence of complications or enterotomies (P = .64 and .5743, respectively). CONCLUSIONS: Open-abdomen reconstruction presents significant challenges. Closure within 6 months is possible; the presence of complications is not affected by early repair.
