Pediatric Trauma System Evaluation before and after Level II Verification.

ACS-verified trauma centers show higher survival and improved mortality rates in states with ACS-verified Level I pediatric trauma centers. However, few significant changes are appreciated in the first two years after verification. Minimal research exists examining verification of ACS Level II pediatric trauma centers. We analyzed ACS Level II pediatric trauma verification at our institution. In 2014, Sanford Medical Center Fargo became the only Level II pediatric trauma center in North Dakota, as well as the only center between Spokane and Minneapolis. A retrospective review of the institution's pre-existing trauma database one year pre- and postverification was performed. Patients aged <18 years were included in the study (P < 0.05). Patient number increased by 23 per cent, from 167 to 205 patients. A statistically significant increase occured in the three to six year old age group (P = 0.0002); motorized recreational vehicle (P = 0.028), violent (P = 0.009), and other (P = 0.0374) mechanism of injury categories; ambulance (P = 0.0124), fixed wing (P = 0.0028), and personal-owned vehicle (P = 0.0112) modes of transportation. Decreased public injuries (P = 0.0071) and advanced life support ambulance transportation (P = 0.0397). The study showed a nonstatistically significant increase in mean Injury Severity Score (from 6.3 to 7) and Native American trauma (from 14 to 20 per cent). Whereas prolonged ACS Level I pediatric trauma center verification was found to benefit patients, minimal data exist on ACS Level II verification. Our findings are consistent with current Level I ACS pediatric trauma center data. Future benefits will require continued analysis because our Level II pediatric trauma center continues to mature and affect our rural and large Native American community.

Interdisciplinary collisions: bringing healthcare professionals together.

Since the publication of its reports, Health professions education: A bridge to quality (2003) and To err is human: Building a safer health system (2000), the Institute of Medicine has continued to emphasize interprofessional education (IPE), founded on quality improvement and informatics, as a better way to prepare healthcare professionals for practice. As this trend continues, healthcare education will need to implement administrative and educational processes that encourage different professions to collaborate and share resources. With greater numbers of students enrolled in health professional programs, combined with ethical imperatives for learning and reduced access to quality clinical experiences, medical and nursing education increasingly rely on simulation education to implement interdisciplinary patient safety initiatives. In this article, the authors describe one approach, based on the Core Competencies for Interprofessional Collaborative Practice released by the Interprofessional Education Collaborative (2011), toward providing IPE to an audience of diverse healthcare professionals in academia and clinical practice. This approach combines professional standards with the authors' practical experience serving on a key operations committee, comprising members from a school of medicine, a school of nursing, and a large healthcare system, to design and implement a new state-of-the-art simulation center and its IPE-centered curriculum.

Learning together: Using simulations to develop nursing and medical student collaboration.

Collaborative interdisciplinary learning is a core educational requirement cited by the Institute of Medicine Health Professions Education Report (2003). This descriptive study supports the Nursing Education Simulation Framework for designing simulations used as an interdisciplinary teaching strategy in health professions curricula. The purpose of this study was to investigate the use of the framework for the collaborative medical and nursing management of a surgical patient with complications. Simulation design features, student satisfaction, and self-confidence were measured. Results indicate both medical and nursing student groups'perceptions of the design features of the collaborative simulation were positive. Feedback and guided reflection were identified by both student groups as important simulation design features. Data analyzed from the Collaboration Scale suggest that designing simulations that place medical and nursing students together is beneficial for both the medical students and the nursing students.

Steroids and poor nutrition are associated with infectious wound complications in children undergoing first stage procedures for ulcerative colitis.

BACKGROUND: Risk factors for postoperative infections have not been evaluated in pediatric patients with ulcerative colitis (UC). This review was undertaken to evaluate the effects of immunosuppressive therapy and other preoperative factors on infectious wound complications in children undergoing first stage surgical therapy for UC. METHODS: A 10-year retrospective review of children under 18 years of age receiving first stage surgical therapy for UC at a major children's hospital was performed. Preoperative clinical and treatment variables were identified and correlated with postoperative wound complications. RESULTS: A total of 51 children were identified: 19 underwent colectomy with ileo-anal-pouch anastomosis and 32 underwent total abdominal colectomy with Hartmann's pouch. A total of 20 infectious complications were identified in 18 patients. Preoperative steroid use was associated with a greater postoperative wound infection rate. Preoperative hemoglobin less than 10 g/dL (P < .05) and albumin less than 3 g/dL (P = 0.1) were associated with greater rates of postoperative infection. Preoperative body mass index and other immunosuppressive agents did not influence postoperative infectious morbidity. CONCLUSIONS: The majority of pediatric patients who require operative intervention for UC are debilitated from their disease and medication use. Children with normal serum albumin and hemoglobin who are not on steroid therapy have a low risk of postoperative infectious complications.

Embryology, sternal clefts, ectopia cordis, and Cantrell's pentalogy.

Sternal clefts, ectopia cordis, and Cantrell's pentalogy continue to be very rare congenital anomalies in pediatric surgery. Unfortunately, these conditions present as neonatal emergencies and demand early surgical intervention. This article reviews the embryological development of the chest wall, specific sternal defect anomalies, along with available methods of treatment.

An evaluation of medication errors-the pediatric surgical service experience.

BACKGROUND: Medication errors in pediatric patients are well recognized. The need for weight-adjusted dosing and changes in pharmacokinetic parameters make this patient population susceptible. Surgical literature discussing this topic is limited. The purpose of this study was to review the medication errors (variances) on surgical services at a major children's teaching hospital. METHODS: Medication variances occurring from January 2004 to June 2006 were reviewed. Data included service, physician, medication, type of variance, severity, explanation of variance, and time of occurrence. RESULTS: There were 757 patients affected hospital-wide by a medication variance (n = 1340) for which 180 patients were on a surgical service (n = 308 variances). Residents accounted for 82% of all variances. Medication variances occurred most frequently on the general (36%) and neurosurgery services (20.5%). Seventy-one percent of the variances were classified as potential to cause harm but were corrected before reaching the patient. Five percent of variances reached the patient and caused temporary harm. Incorrect dose accounted for 72% of variances, followed by incorrect dosage form or omission in 5%, and missed allergies in 4%. Antibiotics were implicated in 31% of variances. Most errors occurred during daytime work hours. CONCLUSION: Our data show that most of prescribing medication variances never reached the patient and were recognized by pharmacy or nursing. There is a continued need to enhance local education (resident) using a service-specific clinical pharmacist to focus on appropriate dosing especially in regard to antibiotics. Computerized physician order entry when implemented will help to minimize some of these errors. However, in the interim, a service-specific medication dosing card is being implemented. Quarterly service-specific data will be incorporated into the resident/fellow clinical conferences to minimize future variance occurrences.

Laparoscopic splenic procedures in children: experience in 231 children.

OBJECTIVES: The purpose of this report is to evaluate the efficacy of and complications observed after laparoscopic splenic procedures in children. METHODS: Review of a prospective database at a single institution (1995-2006) identified 231 children (129 boys; 102 girls; average age 7.69 years) undergoing laparoscopic splenic procedures. RESULTS: Two hundred twenty-three children underwent laparoscopic splenectomy (211 total; 12 partial) by the lateral approach. Indication for splenectomy was hereditary spherocytosis (111), immune thrombocytopenic purpura (36), sickle cell disease (SCD) (51), and other (25). Four (2%) required conversion to an open procedure. Eight additional laparoscopic splenic procedures were performed: splenic cystectomy for epithelial (4) or traumatic (2) cyst, and splenopexy for wandering spleen (2). Average length of stay was 1.5 days. Complications (11% overall, 22% in SCD patients) included ileus (5), bleeding (4), acute chest syndrome (5), pneumonia (2), portal vein thrombosis (1), priapism (1), hemolytic uremic syndrome (1), diaphragm perforation (2), colonic injury (1), missed accessory spleen (1), trocar site hernia (1), subsequent total splenectomy after an initial partial (1), and recurrent cyst (1). Subsequent operations were open in 3 (colon repair, hernia, and missed accessory spleen) and laparoscopic in 2 (completion splenectomy, and cyst excision). There were no deaths, wound infections, or instances of pancreatitis. CONCLUSIONS: Laparoscopic splenic procedures are safe and effective in children and are associated with low morbidity, higher complication rate in SCD, low conversion rate, zero mortality, and short length of stay. Laparoscopic splenectomy has become the procedure of choice for most children requiring a splenic procedure.

Minimal access thoracic surgery in the pediatric population.

Thoracoscopy was initially described for use in children to obtain pulmonary biopsy samples in the immunocompromised patient. With refinements in technique, development of better instrumentation, and advances in pediatric anesthesia, there are now many diagnostic and therapeutic indications for the use of thoracoscopy in children. One of the most common indications includes pleural debridement for empyema. Many centers consider this the optimal approach for biopsy of mediastinal lesions and excision of bronchogenic or duplication cysts. The technique is useful for pleural disorders, such as spontaneous pneumothorax and chylothorax. Thoracoscopy has been used to achieve exposure for spinal diskectomy in children with thoracic scoliosis, and newer techniques are being developed in performing anatomic lobectomies, repair of esophageal atesias, and closure of diaphragmatic hernias. The role of the robot in pediatric thoracoscopy is still in the early stages of definition.

Incidence of persistent left superior vena cava in esophageal atresia.

PURPOSE: Esophageal atresia is known to be associated with a variety of additional congenital anomalies in multiple organ systems. Emphasis on cardiovascular anomalies has been focused on aortic arch and intrinsic cardiac malformations. Persistent left superior vena cava (PLSVC) is the most common venous thoracic anomaly in the general population and creates a problem when central venous access is required. This review was undertaken to define the incidence of PLSVC in infants with esophageal atresia and to determine if any subgroup of associated anomalies poses additional risk. METHODS: A retrospective, institutional review board-approved review of all children treated for esophageal atresia from 1993 to 2002 at Riley Hospital for Children was undertaken. Of 118 children, 89 had sufficient data for inclusion. Charts were reviewed for gestational age, weight, type of atresia, echocardiogram, and associated anomalies. Statistical analysis was performed using the Fisher's Exact test. RESULTS: Of 89 children, 8 (9.9%; confidence interval, 4%-17%) had PLSVC compared with the reported incidence of 0.3% in the general population. Presence of additional organ system anomalies did not significantly increase relative risk for PLSVC. CONCLUSION: The incidence of PLSVC is significantly increased in children with esophageal atresia when compared with the general population. This increased incidence of PLSVC is not influenced by the presence of cardiac or other associated anomalies. This finding should be kept in mind when central venous access is required in this patient population.

The whole truth: comparative analysis of diaphragmatic hernia repair using 4-ply vs 8-ply small intestinal submucosa in a growing animal model.

BACKGROUND: Diaphragmatic reconstruction remains a challenging problem. There is limited information concerning the use of small intestinal submucosa (SIS) in congenital diaphragmatic hernia repair. A canine model was used to evaluate the use of a SIS patch in diaphragmatic reconstruction. METHODS: Eleven beagle puppies (1.6-4.2 kg, 8 weeks old) underwent left subcostal laparotomy, central left hemidiaphragm excision (2 x 7 cm, 50% loss), and reconstruction with a 4-ply group I (n = 5) or 8-ply group II (n = 6) SIS patch. Chest radiographs were taken at time of operation and 3 and 6 months postoperatively. Animals were killed at 6 months. Adhesion formation (both pleural and abdominal), gross visual evaluation of the patch, and histology were compared. RESULTS: In group I (4-ply), 1 animal died at 3 months from patch deterioration accompanied by stomach herniation that resulted in respiratory failure. In the 4 remaining animals, chest radiographs showed no evidence of herniation or eventration. On physical examination, there was no evidence of chest wall deformity. During gross surgical examination, the 4-ply patches showed thinning, multiple defects, and liver herniation in 3 animals. In 1 pup, the patch was thickened, intact, well incorporated at the repair site, and adherent to the liver and spleen. In group II (8-ply), 1 animal died of cardiopulmonary failure in the early postoperative period. In the other 5 animals, chest radiographs showed evidence of eventration in 1. On gross examination the patch adhered to the liver in all 5 surviving animals. In 4, the patches were thickened, viable, but had some shrinkage. One patch pulled away from the native diaphragm laterally; however, no visceral herniation was present. In the 1 animal with eventration, there was no evidence of a patch. Adhesion scores (AS) were graded and determined by the sum of extent (0-4), type (0-4), and tenacity (0-3). Average abdominal AS in group I was 5.6 +/- 0.8 vs 10.2 +/- 0.2 (P = .079) for group II. Average lung AS was 0.6 +/- 0.6 in group I vs 3.8 +/- 1.1 (P = .0476) for group II. Histological examination showed group II patches had greater collagen deposition with central calcification and mild inflammation within the residual graft, whereas group I patches were much thinner and were composed of granulation tissue without evidence of residual graft. CONCLUSIONS: These data indicate that 8-ply SIS repair of diaphragmatic defects was superior (80%; 4/5 to 4-ply, 20%; 1/5, success). Organ adherence appears to be necessary for neovascularization of the SIS composite. Eight-ply grafts appear to be more durable and persist for a longer period, which may improve neovascularization. Long-term follow-up to evaluate remodeling characteristics of the patch material is required.

Surgical considerations in cystic fibrosis: a 32-year evaluation of outcomes.

BACKGROUND: Information concerning long-term operative outcomes in patients with cystic fibrosis (CF) is relatively sparse in the operative literature. METHODS: A retrospective review of CF patients with operative conditions was performed (1972-2004) at a tertiary children's hospital to analyze outcomes including long-term morbidity and survival. RESULTS: A total of 226 patients with CF presented with an operative diagnosis (113 men, 113 women). A total of 422 operations were performed in 213 patients (94%). The mean age at operation was 4.1 +/- 6.2 years (range, 1 d to 26 y) and 109 were neonates. Fifteen of 42 (36%) babies with simple meconium ileus (MI) were treated nonoperatively with hypertonic enemas, 27 of 42 and all 45 patients with complicated MI required operation, including 15 with jejunoileal atresia (17%). Seventeen of 27 (63%) patients with meconium ileus equivalent had MI as neonates; 7 of 27 (26%) required operation. Eight of 9 (89%) with fibrosing colonopathy required operation. Organ transplantation was required in 21 patients. Follow-up evaluation was possible in 204 of 213 (96%) patients. The duration of follow-up evaluation was 14.9 +/- 8.5 years (range, 2 mo to 35 y). Operative morbidity was 11% at 1 year, 2% at 2 to 4 years, 1% at 5 to 10 years, and less than 1% at more than 10 years. There were 24 deaths (11%); 22 followed CF-related pulmonary complications and included 8 of 16 (50%) children with pneumothorax. CONCLUSIONS: Long-term survival in CF patients has improved significantly (89%), with many surviving into the fourth decade. MI may predispose to late complications including meconium ileus equivalent and fibrosing colonopathy. Pneumothorax in CF patients is an ominous predictor of mortality. Children with CF are living longer and are good candidates for operation, but require long-term follow-up evaluation because of ongoing exocrine dysfunction.

Long-term outcomes in total colonic aganglionosis: a 32-year experience.

BACKGROUND/METHODS: A 32-year retrospective review from 1972 to 2004 analyzed complications and long-term outcomes in children with total colonic aganglionosis (TCA) as they relate to the procedure performed. RESULTS: Thirty-six patients (27 boys, 9 girls) had TCA. The level of aganglionosis was distal ileum (26), mid-small bowel (8), midjejunum (1), and entire bowel (1). Enterostomy was performed in 35 of 36. Eight developed short bowel syndrome. Twenty-nine (81%) had a pull-through at 15 +/- 6 months (modified Duhamel 20, Martin long Duhamel 4, and Soave 5). Six had a Kimura patch. Postoperative complications (including enterocolitis) were more common after long Duhamel and Soave procedures. Seven (19%; 2 with Down's syndrome) died (3 early, 4 late) from pulmonary emboli (1), sepsis (1), fluid overload (1), viral illness (1), liver failure (1), arrhythmia (1), and total bowel aganglionosis (1). Mean follow-up was 11 +/- 9 years (range, 6 months-29 years). Twenty-four (83%) of 29 patients exhibited growth by weight of 25% or more, 21 (91%) of 23 older than toddler age had 4 to 6 bowel movements per day, and 17 (81%) of 21 were continent. In 5 of 6, the Kimura patch provided functional benefit with proximal disease. CONCLUSION: Long-term survival was 81%. The highest morbidity occurred with long Duhamel or Soave procedures. The modified Duhamel is our procedure of choice in TCA. Bowel transplantation is an option for TCA with unadapted short bowel syndrome.

Supraumbilical pyloromyotomy: a unique indication for antimicrobial prophylaxis.

BACKGROUND: The umbilical fold incision for infantile hypertrophic pyloric stenosis provides a convenient exposure and cosmetically appealing scar. This study investigates the possible difference in infection rates between traditional and supraumbilical approaches for pyloromyotomy. METHODS: All patients who underwent pyloromyotomy for infantile hypertrophic pyloric stenosis at a tertiary pediatric hospital were reviewed. Baseline wound infection rate was determined through review of patients with right upper quadrant incisions (group 1). A nonrandomized comparison was performed between patients with a supraumbilical approach (group 2) and those undergoing supraumbilical incisions after prophylactic antibiotic administration (group 3). RESULTS: Complete records were reviewed on 384 patients over a 6-year period. Demographics and preoperative factors were similar among groups. The rate of infection in group 1 (n = 258) was 2.3%. With introduction of the supraumbilical approach, there was a statistically significant increase in wound infection rate to 7.0% (chi 2 ; group 1 vs group 2, P < .05). The use of prophylactic antibiotics with a supraumbilical approach reduced this rate of infection back to 2.3% (chi 2 ; group 1 vs group 3, P < 1.0 and group 2 [n = 85] vs group 3 [n = 42], P < .3). CONCLUSIONS: The risk of wound infection by classic pyloromyotomy of 2.3% is significantly increased with an open supraumbilical approach. The use of prophylactic antibiotics reduces this risk of wound infection.

Predictors of successful outcome after cholecystectomy for biliary dyskinesia.

PURPOSE: Laparoscopic cholecystectomy is accepted therapy for children with ill-defined abdominal pain and impaired gallbladder emptying (biliary dyskinesia). Follow-up shows poor clinical response in many of these patients. The purpose of this report is to identify clinical and radiographic predictors of successful outcome after cholecystectomy for biliary dyskinesia. METHODS: The authors retrospectively reviewed records of 51 children after laparoscopic cholecystectomy for biliary dyskinesia (1990 to 2003). Clinical symptoms, radiographic findings, and pathology were evaluated. Subjective clinical improvement is stratified using an established patient satisfaction score. Logistic regression analysis determines statistically independent predictors of successful outcome. RESULTS: Thirty-eight of 51 (75%) patients were available for follow-up. Twenty-seven of 38 (71%) patients reported complete resolution of symptoms. Nausea was the only symptom predictive of successful outcome by univariate analysis (odds ratio, 5.00). A cholecystokinin-stimulated, gallbladder ejection fraction less than 15% also predicts successful outcome (odds ratio, 8.00). Children with an ejection fraction greater than 15% did not have predictable resolution of symptoms. When present with pain and nausea, gallbladder emptying less than 15% has a positive predictive value of 93% and a negative predictive value of 81%. CONCLUSIONS: Together, nausea, pain, and decreased gallbladder emptying (<15%) most reliably predict which children will benefit from cholecystectomy for biliary dyskinesia.

Duodenal atresia and stenosis: long-term follow-up over 30 years.

BACKGROUND: Duodenal atresia and stenosis is a frequent cause of congenital, intestinal obstruction. Current operative techniques and contemporary neonatal critical care result in a 5% morbidity and mortality rate, with late complications not uncommon, but unknown to short-term follow-up. METHODS: A retrospective review of patients with duodenal anomalies was performed from 1972 to 2001 at a tertiary, children's hospital to identify late morbidity and mortality. RESULTS: Duodenal atresia or stenosis was identified in 169 patients. Twenty children required additional abdominal operations after their initial repair with average follow-up of 6 years (range, 1 month to 18 years) including fundoplication (13), operation for complicated peptic ulcer disease (4), and adhesiolysis (4). Sixteen children underwent revision of their initial repair: tapering duodenoplasty or duodenal plication (7), conversion of duodenojejunostomy to duodenoduodenostomy (3), redo duodenojejunostomy (3), redo duodenoduodenostomy (2), and conversion of gastrojejunostomy to duodenoduodenostomy (1). There were 10 late deaths (range, 3 months to 14 years) attributable to complex cardiac malformations (5), central nervous system bleeding (1), pneumonia (1), anastomotic leak (1), and multisystem organ failure (2). CONCLUSIONS: Late complications occur in 12% of patients with congenital duodenal anomalies, and the associated late mortality rate is 6%, which is low but not negligible. Follow-up of these patients into adulthood is recommended to identify and address these late occurrences.

Long-term results of treatment of Hirschsprung's disease.

Many children with Hirschsprung's disease (HD) have a good outcome following surgical treatment, but long-term follow-up studies have identified a number of concerns. Analysis of long-term function in children after surgical management is difficult. The most commonly encountered problems include constipation, incontinence, enterocolitis and the overall impact of the disease on lifestyle (quality of life). Other complications are less frequent. Each of these problems will be discussed.

Do you know your students' basic clinical skills exposure?

BACKGROUND: Undergraduate medical education in the United States is changing. Many medical schools have developed a set of basic clinical skills (BCS) that all students are required to have mastered; however, very few have acquired objective information regarding specific student experiences. The purpose of this study was to determine the BCS encounters for junior medical students at a large midwestern university utilizing a handheld personal digital assistant (PDA). METHODS: A core curriculum of BCS was proposed and involved 52 procedures/skills. An electronic BCS database was developed utilizing HanDBase software and then placed on a PDA (Palm) and distributed to 25 third-year medical students randomly as they entered their clinical year. Students logged their skill encounters for 9 months and then electronically transferred the database by e-mail. RESULTS: Students participated in 1,115 procedural/skill encounters (range 17 to 90; median 41; average 44.6). Of the 52 core BCS, all students performed 10. Fewer than 50% of students had any exposure to very common skills. Thirty-four percent of skill encounters occurred at a county hospital, 19% at a clinic, 10% at a university hospital, 10% at a private hospital, 7% at a VA hospital, 4% at a children's hospital, and 16% at miscellaneous locations. CONCLUSIONS: The PDA devices were simple and convenient to use, while allowing for easy transfer and tabulation of database information by electronic mail. Significant gaps in BCS exposure were noted across the curriculum. Mentor sign-off on the PDA permitted early feedback opportunities. We can now begin to reward educators for skills mentoring and perform formal assessment of BCS within specific clerkships to enhance future educational objectives.

Intravenous catheter training system: computer-based education versus traditional learning methods.

BACKGROUND: Virtual reality simulators allow trainees to practice techniques without consequences, reduce potential risk associated with training, minimize animal use, and help to develop standards and optimize procedures. Current intravenous (IV) catheter placement training methods utilize plastic arms, however, the lack of variability can diminish the educational stimulus for the student. This study compares the effectiveness of an interactive, multimedia, virtual reality computer IV catheter simulator with a traditional laboratory experience of teaching IV venipuncture skills to both nursing and medical students. METHODS: A randomized, pretest-posttest experimental design was employed. A total of 163 participants, 70 baccalaureate nursing students and 93 third-year medical students beginning their fundamental skills training were recruited. The students ranged in age from 20 to 55 years (mean 25). Fifty-eight percent were female and 68% percent perceived themselves as having average computer skills (25% declaring excellence). The methods of IV catheter education compared included a traditional method of instruction involving a scripted self-study module which involved a 10-minute videotape, instructor demonstration, and hands-on-experience using plastic mannequin arms. The second method involved an interactive multimedia, commercially made computer catheter simulator program utilizing virtual reality (CathSim). RESULTS: The pretest scores were similar between the computer and the traditional laboratory group. There was a significant improvement in cognitive gains, student satisfaction, and documentation of the procedure with the traditional laboratory group compared with the computer catheter simulator group. Both groups were similar in their ability to demonstrate the skill correctly. CONCLUSIONS; This evaluation and assessment was an initial effort to assess new teaching methodologies related to intravenous catheter placement and their effects on student learning outcomes and behaviors. Technology alone is not a solution for stand alone IV catheter placement education. A traditional learning method was preferred by students. The combination of these two methods of education may further enhance the trainee's satisfaction and skill acquisition level.

Surgical management of duodenal injuries in children.

BACKGROUND: The goal of this study was to review current injury characteristics, severity, intervention, and outcome of duodenal injuries from a single, pediatric trauma facility. METHODS: A retrospective review was performed of duodenal injuries in children less than 16 years of age from 1990 to 2000. RESULTS: Twelve children had duodenal injuries as a result of blunt abdominal trauma. Six injuries were the result of motor vehicle crashes. Nonaccidental trauma (2) and contact injury (4) provided the remaining cases. Diagnosis was achieved by abdominal computed tomography. Severity of duodenal injury included grade I (1), II (8), and III (3). Seven patients had associated visceral or neurologic injuries. Average Injury Severity Score was 18. Duodenal repair was required in 9 of the 10 patients explored. Treatment included observation (3); primary repair, alone, (2) or with proximal decompression (4); and pyloric exclusion with gastrojejunostomy (3). Exclusion techniques had fewer complications (0% vs 57%) and fewer hospital days (19 vs 23). CONCLUSIONS: Blunt abdominal trauma remains the most prevalent mechanism for pediatric duodenal injuries. Patients undergoing pyloric exclusion for severe duodenal trauma had a lesser morbidity and a shorter hospital stay in this small series. Pyloric exclusion remains an alternative for the treatment of severe duodenal injuries in selected children.

Laparoscopic splenectomy has become the gold standard in children.

Splenectomy is frequently required in children with various hematologic disorders. The reported advantages of laparoscopic splenectomy (LS) include less pain, shorter hospital stay, and improved cosmesis. This report evaluates the outcome of children undergoing LS at a single children's facility. One hundred twelve children underwent LS by the lateral approach between August 1995 and February 2001. Indications for LS were hereditary spherocytosis in 58, idiopathic thrombocytopenic purpura in 21, sickle cell disease in 19, and other conditions in 14. LS alone was completed in 89 children and LS and cholecystectomy (LSC) in 20. Three required conversion to open splenectomy. Accessory spleens were identified in 19. Complications included ileus (four), acute chest syndrome (four), bleeding (two), pneumonia (one), and diaphragm perforation (one). There was no mortality. An accessory spleen was missed in one child with recurrent anemia. Average operative time for LS was 106 minutes and for LSC 135 minutes. Operative time for LS decreased with experience but the difference was not significant. Average length of stay was 1.51 days (range 1-11) and was longer in sickle cell disease (2.47 days) versus hereditary spherocytosis (1.29 days) and idiopathic thrombocytopenic purpura (1.16 days). We conclude that LS is safe and effective in children with hematologic disorders and is associated with minimal morbidity, zero mortality, and a short length of stay.
