J Pediatr Surg 2024; 59:1477-1485. [PMID: 38565474 DOI: 10.1016/j.jpedsurg.2024.03.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 02/09/2024] [Accepted: 03/09/2024] [Indexed: 04/04/2024]
Abstract
OBJECTIVE Complicated appendicitis is associated with a higher risk of postoperative complications, including adhesive bowel obstruction. The aim of this meta-analysis is to investigate the difference in rates of postoperative bowel obstruction in paediatric patients with complicated versus simple appendicitis and whether this is influenced by the surgical approach. METHODS A systematic literature search following PRISMA guidelines was conducted using MEDLINE, Embase and Cochrane Library for studies that analysed incidence of adhesive bowel obstruction in paediatric patients after appendicectomy. Studies from 1998 to 2022 were included in analysis. The study protocol was registered on PROSPERO (ID CRD42022309769). RESULTS Pooled analysis of 6 studies with low risk of bias and adequate follow up periods, considering 58,962 cases of appendicectomy, revealed complex appendicitis was associated with a near two-fold increase in incidence of SBO (pooled odds ratio 2.02 (95% CI 1.35-2.69)). Interestingly, a similar pooled analysis of 10 studies, considering 62,433 cases of appendicectomy, revealed no significant difference between open and laparoscopic management of complex appendicitis (pooled odds ratio 0.93 (95% CI 0.24 to 1.62)). CONCLUSION Complex appendicitis is associated with a two-fold increase in the rates of adhesive bowel obstruction. Whilst there are cosmetic advantages of a laparoscopic approach, surgical expertise should be favoured in decision making relating to surgical approach (laparoscopic versus open) as the evidence for a laparoscopic approach reducing risks of adhesive bowel obstruction is not convincing.

Abstract
BACKGROUND Despite widespread initiatives to reduce ionizing radiation for appendicitis diagnosis, computed tomography (CT) scanning postoperatively remains common. The Pediatric Surgery Quality Collaborative (PSQC) aimed to identify differences between children's hospitals with high and low postoperative CT usage for complicated appendicitis. METHODS Using National Surgery Quality Improvement Program Pediatric data from PSQC children's hospitals, we compared postoperative CT imaging for complicated appendicitis (April 2020-March 2021). Key stakeholders from 11 hospitals (5 low CT utilization, 6 high CT utilization) participated in semi-structured interviews regarding postoperative imaging. Qualitative analysis of transcripts was performed deductively and inductively based on the Theoretical Domains Framework (TDF). RESULTS Five of twelve TDF domains were most prominent in influencing CT use: skills, beliefs about capabilities, intentions/goals, memory and decision processes, and environment. Children's hospitals with lower rates of postoperative CT use tended to: trust and educate the ultrasound technicians; believe US strengths outweigh weaknesses; image no sooner than 7 days postoperatively; have access to sufficient quality improvement resources; maintain trusting relationships between specialties; and prioritize radiation stewardship. CONCLUSION Hospitals at extremes of postoperative CT use for complicated appendicitis reveal strategies for improvement, which include imaging protocol development and adherence, quality improvement resource availability, interdisciplinary collaboration, and promoting radiation stewardship.

Abstract
BACKGROUND Appendectomy remains a common pediatric surgical procedure with an estimated 80,000 operations performed each year. While prior work has reported the existence of racial disparities in postoperative outcomes, we sought to characterize potential income-based inequalities using a national cohort. METHODS All non-elective pediatric (<18 years) hospitalizations for appendectomy were tabulated in the 2016-2020 National Inpatient Sample. Only those in the highest (HI) and lowest income (LI) quartiles were considered for analysis. Multivariable regression models were developed to assess the independent association of income and postoperative major adverse events (MAE). RESULTS Of an estimated 87,830 patients, 36,845 (42.0%) were HI and 50,985 (58.0%) were LI. On average, LI patients were younger (11 [7-14] vs 12 [8-15] years, P < .001), more frequently insured by Medicaid (70.7 vs 27.3%, P < .05), and more commonly of Hispanic ethnicity (50.8 vs 23.4%, P < .001). Following risk adjustment, the LI cohort was associated with greater odds of MAE (adjusted odds ratio [AOR] 1.30 95% confidence interval [CI] 1.06-1.64). Specifically, low-income status was linked with increased odds of infectious (AOR 1.65, 95% CI 1.12-2.42) and respiratory (AOR 1.67, 95% CI 1.06-2.62) complications. Further, LI was associated with a $1670 decrement in costs ([2220-$1120]) and a +.32-day increase in duration of stay (95% CI [.21-.44]). CONCLUSION Pediatric patients of the lowest income quartile faced increased risk of major adverse events following appendectomy compared to those of highest income. Novel risk stratification methods and standardized care pathways are needed to ameliorate socioeconomic disparities in postoperative outcomes.

Can magnetic resonance imaging replace computed tomography scans in the evaluation of pediatric post-appendectomy abscess? Surgery 2023; 174:703-708. [PMID: 37365084 DOI: 10.1016/j.surg.2023.05.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/03/2023] [Accepted: 05/24/2023] [Indexed: 06/28/2023]
Abstract
BACKGROUND Computed tomography scans have been used when cross-axial imaging is required to evaluate pediatric post-appendectomy abscesses. To reduce a source of radiation exposure, our institution converted to using contrast-enhanced magnetic resonance imaging to replace computed tomography scans in this clinical context. Our aim is to evaluate the performance of magnetic resonance imaging compared to computed tomography scans and associated clinical outcomes in this patient population. METHODS A contrast-enhanced comprehensive magnetic resonance imaging protocol was implemented to evaluate a post-appendectomy abscess in 2018. A retrospective chart review was performed from 2015 to 2022 for pediatric patients (<18 years old) with prior appendectomy and subsequent cross-sectional imaging to evaluate for an intraabdominal abscess. Patient characteristics and clinical parameters between the 2 modalities were abstracted and compared using standard univariate statistics. RESULTS There were a total of 72 post-appendectomy patients who received cross-axial imaging, which included 43 computed tomography scans and 29 magnetic resonance imaging during the study interval. Patient demographics were comparable between cohorts and rates of perforated appendicitis at the index operation (computed tomography: 79.1% vs magnetic resonance imaging: 86.2%). Missed abscess rate, abscess size, management technique, drainage culture results, readmission, and reoperation were similar between imaging modalities. Median request to scan time was longer for magnetic resonance imaging than computed tomography (191.5 vs 108 minutes, P = .04). The median duration of a comprehensive magnetic resonance imaging scan was 32 minutes (interquartile range 28-50.5 minutes). CONCLUSION Contrast-enhanced magnetic resonance imaging provides an alternative cross-sectional imaging modality to computed tomography scans to evaluate pediatric post-appendectomy abscesses.

Abstract
INTRODUCTION Imaging-confirmed uncomplicated acute appendicitis can be effectively and safely treated with antibiotics in most adults and children. Symptomatic treatment may have similar efficacy and safety. METHODS AND ANALYSIS The APPSYPP trial is a randomized national multicenter feasibility superiority pilot study comparing appendectomy with symptomatic treatment in children with imaging-confirmed uncomplicated acute appendicitis. INCLUSION CRITERIA 1) age ≥ 7 and < 16 years, 2) imaging-confirmed uncomplicated acute appendicitis and 3) CRP ≤ 65 mg/l. Patients are randomized to receive emergency laparoscopic appendectomy or symptomatic treatment. To ensure patient safety, symptomatically treated patients are hospitalized for at least 24 h receiving standard practice intravenous fluids and analgesics according to standard clinical practice. Primary outcome is 30-day treatment success defined by the absence of any treatment failure criteria. In appendectomy, treatment failure is defined as normal appendiceal histopathology or any postintervention complication requiring general anesthesia. In symptomatic treatment, treatment failure is defined as 1) inability for hospital discharge without appendectomy within 48 h after randomization with a finding of histopathologically inflamed appendix, 2) appendectomy during the initial hospital stay due to clinical progression of appendicitis with complicated acute appendicitis both histopathologically and surgically, 3) appendectomy with a histopathological finding of acute appendicitis after hospital discharge, or 4) any complication of appendicitis requiring general anesthesia. Detailed predefined secondary outcomes will be analyzed. ETHICS AND DISSEMINATION Study was approved by Ethics Committee of Helsinki University Hospital (ID:HUS/1993/2021), conducted in compliance with the declaration of Helsinki with results disseminated in peer-reviewed scientific journals. TRIAL REGISTRATION ClinicalTrials.gov (NCT05289713). STRENGTHS AND LIMITATIONS OF THIS STUDY

Abstract
Appendicitis remains a common disease entity in pediatric patients that has historically been treated surgically with appendectomy as the standard of care. The coronavirus disease 2019 (COVID-19) pandemic introduced widespread challenges impacting the management and treatment of various disease processes, including pediatric appendicitis. Many studies demonstrated a decreased incidence in pediatric appendicitis cases, which may be attributable to fears of contracting the COVID-19 virus and restrictions imposed with stay-at-home orders. Many studies have noted both an increase in nonoperative management of pediatric appendicitis and a rise in patients presenting with complicated appendicitis. Additionally, the development of multisystem inflammatory syndrome in children that may present with symptoms mimicking appendicitis has created a diagnostic dilemma for pediatric care providers. Understanding the natural history of pediatric appendicitis during the COVID-19 pandemic and additional diagnostic and treatment difficulties are essential to ensure accurate care of pediatric patients that present with abdominal pain concerning for appendicitis.

Abstract
IMPORTANCE The factors associated with the failure of nonoperative management of appendicitis and the differences in patient-reported outcomes between successful and unsuccessful nonoperative management remain unknown. OBJECTIVES To investigate factors associated with the failure of nonoperative management of appendicitis and compare patient-reported outcomes between patients whose treatment succeeded and those whose treatment failed. DESIGN, SETTING, AND PARTICIPANTS This study was a planned subgroup secondary analysis conducted in 10 children's hospitals that included 370 children aged 7 to 17 years with uncomplicated appendicitis enrolled in a prospective, nonrandomized clinical trial between May 1, 2015, and October 31, 2018, with 1-year follow-up comparing nonoperative management with antibiotics vs surgery for uncomplicated appendicitis. Statistical analysis was performed from November 1, 2019, to February 12, 2022. INTERVENTIONS Nonoperative management with antibiotics vs surgery. MAIN OUTCOMES AND MEASURES Failure of nonoperative management and patient-reported outcomes. The relative risk (RR) of failure based on sociodemographic and clinical characteristics was calculated. Patient-reported outcomes were compared based on the success or failure of nonoperative management. RESULTS Of 370 patients (34.6% of 1068 total patients; 229 boys [61.9%]; median age, 12.3 years [IQR, 10.0-14.6 years]) enrolled in the nonoperative group, treatment failure occurred for 125 patients (33.8%) at 1 year, with 53 patients (14.3%) undergoing appendectomy during initial hospitalization and 72 patients (19.5%) experiencing delayed treatment failure after hospital discharge. Higher patient-reported pain at presentation was associated with increased risk of in-hospital treatment failure (RR, 2.1 [95% CI, 1.0-4.4]) but not delayed treatment failure (RR, 1.3 [95% CI, 0.7-2.3]) or overall treatment failure at 1 year (RR, 1.5 [95% CI, 1.0-2.2]). Pain duration greater than 24 hours was associated with decreased risk of delayed treatment failure (RR, 0.3 [95% CI, 0.1-1.0]) but not in-hospital treatment failure (RR, 1.2 [95% CI, 0.5-2.7]) or treatment failure at 1 year (RR, 0.7 [95% CI, 0.4-1.2]). There was no increased risk of treatment failure associated with age, white blood cell count, sex, race, ethnicity, primary language, insurance status, transfer status, symptoms at presentation, or imaging results. Health care satisfaction at 30 days and patient-reported, health-related quality of life at 30 days and 1 year were not different. Satisfaction with the decision was higher with successful nonoperative management at 30 days (28.0 vs 27.0; difference, 1.0 [95% CI, 0.01-2.0]) and 1 year (28.1 vs 27.0; difference, 1.1 [95% CI, 0.2-2.0]). CONCLUSIONS AND RELEVANCE This analysis suggests that a higher pain level at presentation was associated with a higher risk of initial failure of nonoperative management and that a longer duration of pain was associated with lower risk of delayed treatment failure. Although satisfaction was high in both groups, satisfaction with the treatment decision was higher among patients with successful nonoperative management at 1 year.

Abstract
Introduction An American College of Surgeons (ACS) Level-I (L-I) pediatric trauma center demonstrated successful laparoscopy without conversion to laparotomy in ∼65% of trauma cases. Prior reports have demonstrated differences in outcomes based on ACS level of trauma center. We sought to compare laparoscopy use for blunt abdominal trauma at L-I compared to Level-II (L-II) centers. Methods The Pediatric Trauma Quality Improvement Program was queried (2014-2016) for patients ≤16 years old who underwent any abdominal surgery. Bivariate analyses comparing patients undergoing abdominal surgery at ACS L-I and L-II centers were performed. Results 970 patients underwent abdominal surgery with 14% using laparoscopy. Level-I centers had an increased rate of laparoscopy (15.6% vs 9.7%, P = .019 ); however they had a lower mean Injury Severity Score (16.2 vs 18.5, P = .002) compared to L-II centers. Level-I and L-II centers had similar length of stay ventilator days, and SSIs (all P > .05). Conclusion While use of laparoscopy for pediatric trauma remains low, there was increased use at L-I compared to L-II centers with no difference in LOS or SSIs. Future studies are needed to elucidate which pediatric trauma patients benefit from laparoscopic surgery.

[PMID: 33549307 DOI: 10.1016/j.jpedsurg.2021.01.032] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 01/14/2021] [Accepted: 01/18/2021] [Indexed: 01/09/2023]
Abstract
INTRODUCTION Inguinal hernia repairs (IHR) are commonly performed by pediatric surgeons in the United States. The operative approach depends on surgeon preference with no definitive prospective studies comparing laparoscopic inguinal hernia repair (LIHR) versus traditional inguinal hernia repair (TIHR). We aim to assess current practice, hypothesizing that laparoscopy is increasingly used for pediatric IHR. MATERIAL & METHODS The Children's Hospital Association (CHA) Pediatric Health Information System was queried for IHRs performed between 01/01/2009 and 12/31/2018. Demographics, procedure type, hernia laterality, and cost were obtained. Patients were grouped by procedure type (laparoscopic/traditional). RESULTS 125,249 IHRs were performed at 32 CHA hospitals during the ten-year study period. 115,782 (92.4%) were TIHR and 9467 (7.6%) LIHR. Use of laparoscopy increased 5-fold from 3% to 15% over the study period. When comparing laparoscopic to traditional IHR groups, there were more females (28.3% vs 12.6%), African-Americans (19.7% vs 14.4%), government-insured (50% vs 45.2%), younger patients (4.2 vs 4.4 years), bilateral IHRs (11.4% vs 7.9%), and higher adjusted total hospital cost ($3,791 vs $2995) in the laparoscopic group (p<0.0001, all comparisons). CONCLUSIONS Laparoscopy for pediatric IHR is increasing at CHA hospitals where nearly 1 in 6 children currently undergoes a laparoscopic repair. The long-term outcomes with laparoscopic repair are worthy of future study.

Abstract
Background: Laparoscopic surgery has become the standard of care for many surgical treatments. The diffusion of laparoscopy has been investigated for adult patient populations but is still unknown for pediatric populations. This study sought to describe national trends in diffusion of laparoscopic surgery for common pediatric conditions and identify disparities in use of laparoscopic surgery. Study Design: A retrospective analysis of serial cross-sectional data was performed using the Healthcare Cost and Utilization Project's Kids' Inpatient Database from 1997 to 2016. Pediatric patients (ages ≤18) undergoing appendectomy, cholecystectomy, fundoplication, or inguinal hernia repair were identified. The diffusion of laparoscopy for each procedure was measured using the proportion of laparoscopic surgeries over years. Results: National trends demonstrate increases in the use of laparoscopy for children over the past two decades from 13.4% to 88.7% for appendectomy, from 82.6% to 94.9% for cholecystectomy, from 7.4% to 77.4% for fundoplication, and from 1.5% to 23.5% for repair of inguinal hernia (P < .001). Disparities in diffusion of laparoscopy were found from various pediatric populations, and the disparities varied by specific procedures and years. In particular, the proportion of laparoscopic appendectomy in 1997 was 11.3% at urban teaching hospitals and was 13.9% at rural hospitals (P = .01), while the proportions in 2016 increased to 90.8% at urban teaching hospitals versus 71.3% at rural hospitals (P < .001). Conclusions: Laparoscopy has become the standard surgical care for common pediatric surgical conditions. Widening disparities in use of laparoscopic surgery for pediatric populations appear between urban teaching hospitals and rural hospitals.

Abstract
INTRODUCTION Children with appendicitis often present with complicated disease. The aim of this study was to describe the clinical management of pediatric appendicitis, and to report how disease severity and operative modality are associated with short- and long-term risks of adverse outcome. MATERIALS AND METHODS A nationwide retrospective cohort study of all Swedish children (<18 years) diagnosed with appendicitis, 2001 to 2014 (n = 38,939). Primary and secondary outcomes were length of stay, surgical site infections, readmissions, 30-day mortality, and long-term risk of surgery for small bowel obstruction (SBO). Implications of complicated disease and operative modality were assessed with adjustment for age, gender, and trends over time. RESULTS Complicated appendicitis was associated with longer hospital stay (4 vs. 2 days, p < 0.001), increased risk of surgical site infection (5.9 vs. 2.3%, adjusted odds ratio [aOR]: 2.64 [95% confidence interval, CI: 2.18-3.18], p < 0.001), readmission (5.5 vs. 1.2, aOR: 4.74 [95% CI: 4.08-5.53], p < 0.001), as well as long-term risk of surgery for SBO (0.7 vs. 0.2%, adjusted hazard ratio [aHR]: 3.89 [95% CI: 2.61-5.78], p < 0.001). Intended laparoscopic approach was associated with reduced risk of surgical site infections (2.3 vs. 3.1%, aOR: 0.74 [95% CI: 0.62-0.89], p = 0.001), but no overall reduction in risk for SBO; however, successful laparoscopic appendectomy was associated with less SBO during follow-up compared with open appendectomy (aHR: 0.27 [95% CI: 0.11-0.63], p = 0.002). CONCLUSION Children treated for complicated appendicitis are at risk of substantial short- and long-term morbidities. Fewer surgical site infections were seen after intended laparoscopic appendectomy, compared with open appendectomy, also when converted procedures were accounted for.

Abstract
Introduction Appendicitis continues to be one of the most common surgical conditions in the pediatric population. We set out to determine demographic and practice variations among children admitted with appendicitis and highlight the racial/ethnic and healthcare access role in relation to the rate of complicated appendicitis using the 2012 Kids' Inpatient Database (KID). Methodology. A retrospective cross-sectional database study was performed using the 2012 KID. All children (age 1 months to 20 years) with appendicitis were identified using the ICD-9 diagnosis codes. Children with a diagnosis of appendicitis were compared with all other discharges. Among children with appendicitis, demographic and practice variations and the rate of complicated appendicitis were evaluated. Univariate and multivariate analyses were done to analyze the data. Sample weighing was done to present national estimates. Results In 2012, a total of 89, 935 out of 2.7 million pediatric hospital discharges (3.3%) had a diagnosis of appendicitis. The incidence of appendicitis was higher in males (4.7%), 6–15-year age group (7.43%), Hispanics (5.2%), and in the Western region (5.2%) and was lower in infants (0.02%) and African American children (1.2%) (p < 0.0001). The proportion of children with peritonitis or abscess was higher in children's hospitals (48.2% vs. 29.0%; OR 2.3, 95% CI: 2.2–2.4). The risk of complicated appendicitis was inversely related to age, while racial and ethnic minority status, bottom quartile of the income group, and government insurance increased the risk. Laparoscopic appendectomy was performed more frequently at children's hospitals (84.8% vs. 74.3%; p < 0.0001). Conclusions Appendicitis is more common in Hispanics, males, older children, and in the Western region. Complicated appendicitis is more common in younger children, minority groups, low-income group, and children with government insurance. Children's hospitals manage more children with complicated appendicitis and are more likely to perform laparoscopic appendectomy.

Abstract
BACKGROUND We investigated the efficacy of broad-spectrum antibiotics for prevention of postoperative intra-abdominal abscess in pediatric acute appendicitis with our 3 risk factors:-WBC > 16.5 (× 103/µl), CRP > 3.1 (mg/dl) and appendix maximum short diameter on diagnostic imaging > 11.4 mm. METHODS Four hundred twenty-two patients were reviewed. Patients with 0-1 risk factors were assessed as low-risk and those with 2-3 were high-risk. In the low-risk group, Group A (n = 66) patients received broad-spectrum antibiotics and Group B patients (n = 265) received narrow-spectrum monotherapy. In the high-risk group, Group C patients (n = 63) received broad-spectrum antibiotics and Group D patients (n = 28), narrow-spectrum antibiotics. The outcomes were the incidence of postoperative abscess and the total duration of intravenous (IV) antibiotics. RESULTS The incidence of intra-abdominal abscess was 6.06% in Group A versus 1.89% in Group B (p = 0.08), and 19.05% in Group C versus 3.57% in Group D (p = 0.06). Total IV antibiotic duration (days) were 6.12 ± 2.87 in Group A versus 3.83 ± 0.69 in Group B (p < 0.01), and 7.84 ± 4.57 in Group C versus 4.00 ± 0.82 in Group D (p < 0.01). CONCLUSION Broad-spectrum antibiotics did not prevent postoperative intra-abdominal abscess in either low or high-risk groups.

Abstract
OBJECTIVE To assess and compare the post-operative outcomes of open and laparoscopic appendicectomy in children. DESIGN Record linkage analysis of administrative hospital (Admitted Patient Data Collection) and emergency department (Emergency Department Data Collection) data.Participants, setting: Children under 16 years of age who underwent an appendicectomy in a public or private hospital in New South Wales between January 2002 and December 2013. MAIN OUTCOME MEASURES Association between type of appendicectomy and post-operative complications within 28 days of discharge, adjusted for patient characteristics and type of hospital. RESULTS Of 23 961 children who underwent appendicectomy, 19 336 (81%) had uncomplicated appendicitis and 4625 (19%) had appendicitis complicated by abscess, perforation, or peritonitis. The proportion of laparoscopic appendicectomies increased from 11.8% in 2002 to 85.8% in 2013. In cases of uncomplicated appendicitis, laparoscopic appendicectomy was associated with more post-operative complications (mostly symptomatic re-admissions or emergency department presentations) than open appendicectomy (7.4% v 5.8%), but with a reduced risk of post-operative intestinal obstruction (adjusted odds ratio [aOR], 0.59; 95% CI, 0.36-0.97). For cases of complicated appendicitis, the risk of wound infections was lower for laparoscopic appendicectomy (aOR, 0.67; 95% CI, 0.50-0.90), but not the risks of intestinal obstruction (aOR, 0.97; 95% CI, 0.62-1.52) or intra-abdominal abscess (aOR, 1.06; 95% CI, 0.72-1.55). CONCLUSION Post-appendicectomy outcomes were similar for most age groups and hospital types. Children with uncomplicated appendicitis have lower risk of post-operative bowel obstruction after laparoscopic appendicectomy than after open appendicectomy, but may be discharged before their post-operative symptoms have adequately resolved.

Abstract
There is a lack of information about evaluation of pediatric minimal access surgery complications; the Clavien-Dindo classification was never used for a large series of laparoscopic and thoracoscopic pediatric procedures. With a prospective Morbidity and Mortality database, all the minimal access surgical procedures carried out between 2012 and 2016 were included in this study. Statistical analyses were used to valuate modification of surgical techniques in to 2 periods (period 1: January 2012 to February 2014; period 2: February 2014 to February 2016). A total of 1374 minimal access procedures were performed on 1371 patients. The overall complication rate was 2.9%. No differences, in terms of complications, were observed between elective and emergency procedures (P=0.3). There was a significant difference between the complication rate of thoracoscopic surgery (P=0.027). These results provide the relevance of adequate recording system and standardized classification for analyses and reduction of complications for pediatric minimal access procedures.

Abstract
OBJECTIVES To determine the proportion of true-positive blood culture results in children presenting to the ED with suspected appendicitis. To describe the current practice of obtaining blood cultures in children with suspected appendicitis. METHODS We performed a 2-year retrospective health record review of all children aged 2 through 17 years investigated for suspected appendicitis at a tertiary Pediatric Emergency Department. Subjects were identified by searching (a) institutional records for ICD-10-CA coding, (b) diagnostic imaging records of ultrasounds for appendicitis, and (c) surgical database records for nonincidental appendectomies. Abstracted demographic and clinical data were matched to regional laboratory services data to describe the performance and result of blood cultures. RESULTS Overall, 1315 children investigated for appendicitis were reviewed. Seven hundred fifty (57.0%) were girls, the average age was 11.7 years (SD, 4.0). Blood cultures were obtained in 288 (21.9%) of 1315 patients. Of the 11 (3.8%) cultures that were positive, only 1 (0.35%) was a true positive. Young age, high triage acuity, and presence of fever were associated with the acquisition of cultures (P < 0.001 for all). The proportion of children undergoing appendectomy and the negative appendectomy rate was similar between those with and without blood culture (P = 0.10 and P = 0.96, respectively). CONCLUSIONS True-positive blood cultures are very rare in children presenting to the ED with suspected appendicitis. Given the potential for false-positive cultures and the social/economic implications of initial testing/retesting of false positives, the use of routine blood cultures for children with suspected appendicitis is not supported.

Abstract
BACKGROUND Laparoscopic appendectomy is the predominant method of treatment of acute appendicitis. There is insufficient evidence on the most effective management of the appendix stump. The aim of this study was to investigate the relative effectiveness and provide a treatment ranking of different options for securing the appendix stump. METHODS Electronic databases were searched to identify randomized controlled trials comparing ligation methods of the appendix. The primary outcomes were organ/space infection and superficial operative site infection. We performed a network meta-analysis and estimated the pairwise relative treatment effects of the competing interventions using the odds ratio and its 95% confidence interval. We obtained a hierarchy of the competing interventions using rankograms and the surface under the cumulative ranking curve. RESULTS Forty-three randomized controlled trials were eligible and provided data for >5,000 patients. Suture ligation seemed to be the most effective treatment strategy, in terms of both organ/space infection and superficial operative site infection. Statistical significance was reached for the comparisons of clip versus endoloop (odds ratio 0.56, 95% confidence interval, 0.32-0.96) for organ/space infection; and suture versus clip (odds ratio 0.20, 95% confidence interval 0.08-0.55) and clip versus endoloop (odds ratio 2.22, 95% confidence interval 1.56-3.13) for superficial operative site infection. The network was informed primarily by indirect treatment comparisons. CONCLUSION The use of suture ligation of the appendix in laparoscopic appendectomy seems to be superior to other methods for the composite parameters of organ/space and superficial operative site infection.

Abstract
BACKGROUND Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). OBJECTIVE To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms. MATERIALS AND METHODS In this retrospective, institutional review board-approved study, all patients underwent a clinically indicated non-contrast 1.5- or 3-Tesla abdomen/pelvis MRI consisting of single-shot fast spin echo, inversion recovery and DWI sequences. All MRI studies were reviewed by two blinded pediatric radiologists to identify the presence of a drainable fluid collection. Each fluid collection was further characterized as accessible or not accessible for percutaneous or transrectal drainage. Imaging findings were compared to clinical outcome. RESULTS Seven of the 15 patients had a clinically significant fluid collection, and 5 of these patients were treated with percutaneous drain placement or exploratory laparotomy. The other patients had a phlegmon or a clinically insignificant fluid collection and were discharged home within 48 h. CONCLUSION Rapid non-contrast MRI utilizing fluid-sensitive and DWI sequences can be used to identify drainable fluid collections in post-appendectomy patients. This protocol can be used to triage patients between conservative management vs. abscess drainage without oral/intravenous contrast or exposure to ionizing radiation.

Abstract
Background and Objectives: Transumbilical laparoscopic-assisted appendectomy (TULAA) carries a high risk for surgical site infection. We investigated the effect of a bio-occlusive umbilical vacuum dressing on wound infection rates after TULAA for patients with acute appendicitis and compared to it with a conventional 3-port appendectomy with a nonvacuum dressing. Methods: This study was a retrospective chart review of 1377 patients (2–20 years) undergoing laparoscopic appendectomy for acute appendicitis in 2 tertiary care referral centers from January 2007 through December 2012. Twenty-two different operative technique/dressing variations were documented. The 6 technique/dressing groups with >50 patients were assessed, including a total of 1283 patients. Results: The surgical site infection rate of the 220 patients treated with TULAA and application of an umbilical vacuum dressing with dry gauze is 1.8% (95% CI, 0.0–10.3%). This compares to an infection rate of 4.1% (95% CI, 1.3–10.5%) in 97 patients with dry dressing without vacuum. In the 395 patients who received an umbilical vacuum dressing with gauze and bacitracin, the surgical site infection rate was found to be 4.3% (95% CI, 2.7–6.8%). Conclusions: Application of an umbilical negative-pressure dressing with dry gauze lowers the rate of umbilical site infections in patients undergoing transumbilical laparoscopic-assisted appendectomy for acute appendicitis.

Abstract
Appendicitis is a common cause of abdominal pain in children. The diagnosis and treatment of the disease have undergone major changes in the past two decades, primarily as a result of the application of an evidence-based approach. Data from several randomized controlled trials, large database studies, and meta-analyses have fundamentally affected patient care. The best diagnostic approach is a standardized clinical pathway with a scoring system and selective imaging. Non-operative management of simple appendicitis is a reasonable option in selected cases, with the caveat that data in children remain limited. A minimally invasive (laparoscopic) appendectomy is the current standard in US and European children's hospitals. This article reviews the current 'state of the art' in the evaluation and management of pediatric appendicitis.

Abstract
Appendicitis is one of the most common surgical pathologies in children. It can present with right lower quadrant pain. Scoring systems in combination with selective imaging and surgical examination will diagnose most children with appendicitis. Clinical pathways should be used. Most surgical interventions for appendicitis are now almost exclusively laparoscopic, with trials demonstrating better outcomes for children who undergo index hospitalization appendectomies when perforated. Nonoperative management has a role in the treatment of both uncomplicated and complicated appendicitis. This article discusses the workup and management, modes of treatment, and continued areas of controversy in pediatric appendicitis.

Abstract
Appendectomy has been the standard of care for appendicitis since the late 1800s, and remains one of the most common operations performed in children. The advent of data-driven medicine has led to questions about every aspect of the operation-whether appendectomy is even necessary, when it should be performed (timing), how the procedure is done (laparoscopic variants versus open and irrigation versus no irrigation), length of hospital stay, and antibiotic duration. The goal of this analysis is to review the current status of, and available data regarding, the surgical management of appendicitis in children.

Wound classification in pediatric surgical procedures: Measured and found wanting. J Pediatr Surg 2016; 51:1014-6. [PMID: 26996591 DOI: 10.1016/j.jpedsurg.2016.02.070] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Accepted: 02/26/2016] [Indexed: 11/22/2022]
Abstract
PURPOSE Surgical wound classification has emerged as a measure of surgical quality of care, but scant data exist in the era of minimally invasive procedures, especially in children. The aim of this study is to examine the surgical site infection (SSI) rate by wound classification during common pediatric surgical procedures. METHODS A retrospective analysis of the 2013 Pediatric-National Surgical Quality Improvement Program (Peds-NSQIP) dataset was conducted. Patients undergoing pyloromyotomy, cholecystectomy, ostomy reversal, and appendectomy were included. Wound classification, SSI rate, reoperation, and readmission were analyzed. RESULTS A total of 10,424 records were included. Pyloromyotomy, a clean case, had a 0.7% SSI rate, while ostomy reversal, a clean contaminated case, had an SSI in 6.9% of cases. Appendectomy for nonperforated acute appendicitis and laparoscopic cholecystectomy for cholecystitis, both contaminated cases, had SSI rates of 2.1% and <1%, respectively. Appendectomy for perforated appendicitis, a dirty procedure, had a 9.1% SSI rate, below the expected >40% for dirty cases. Reoperations and readmission rates ranged from <1% to 9% and increased with case complexity. CONCLUSION Current wound classifications systems do not reflect surgical risk in children and remain questionable tools for benchmarking surgical care in children. Role of readmissions and reoperations as quality of care indices needs further investigation.

Abstract
OBJECTIVES The objective was to characterize the variations in practice in the diagnosis and management of children admitted to hospitals from Canadian pediatric emergency departments (EDs) with suspected appendicitis, specifically the timing of surgical intervention, ED investigations, and management strategies. METHODS Twelve sites participated in this retrospective health record review. Children aged 3 to 17 years admitted to the hospital with suspected appendicitis were eligible. Site-specific demographics, investigations, and interventions performed were recorded and compared. Factors associated with after-hours surgery were determined using generalized estimating equations logistic regression. RESULTS Of the 619 children meeting eligibility criteria, surgical intervention was performed in 547 (88%). After-hours surgery occurred in 76 of the 547 children, with significant variation across sites (13.9%, 95% confidence interval = 7.1% to 21.6%, p < 0.001). The overall perforation rate was 17.4% (95 of 547), and the negative appendectomy rate was 6.8% (37 of 547), varying across sites (p = 0.004 and p = 0.036, respectively). Use of inflammatory markers (p < 0.001), blood cultures (p < 0.001), ultrasound (p = 0.001), and computed tomography (p = 0.001) also varied by site. ED administration of narcotic analgesia and antibiotics varied across sites (p < 0.001 and p = 0.001, respectively), as did the type of surgical approach (p < 0.001). After-hours triage had a significant inverse association with after-hours surgery (p = 0.014). CONCLUSIONS Across Canadian pediatric EDs, there exists significant variation in the diagnosis and management of children with suspected appendicitis. These results indicate that the best diagnostic and management strategies remain unclear and support the need for future prospective, multicenter studies to identify strategies associated with optimal patient outcomes.

Abstract
Multiple electronic and administrative databases are available for the study of pediatric infectious diseases. In this review, we identify research questions well suited to investigations using these databases and highlight their advantages, including their relatively low cost, efficiency, and ability to detect rare outcomes. We discuss important limitations, including those inherent in observational study designs and the potential for misclassification of exposures and outcomes, and identify strategies for addressing these limitations. We provide examples of commonly used databases and discuss methodologic considerations in undertaking studies using large databases. Last, we propose a checklist for use in planning or evaluating studies of pediatric infectious diseases that employ electronic databases, and we outline additional practical considerations regarding the cost of and how to access commonly used databases.

Abstract
BACKGROUND Although cosmetic superiority is widely stated as an advantage of single-incision laparoscopy, there are limited studies looking at cosmetic outcome. We sought to determine patients' cosmetic satisfaction after undergoing appendectomy by the single-incision laparoscopic appendectomy (SILA), multiport laparoscopic appendectomy (LA), or open appendectomy (OA) procedure. PATIENTS AND METHODS Five hundred eighty pediatric patients who underwent appendectomy at a single institution between February 2010 and July 2011 were identified and asked to complete the Patient Scar Assessment Scale (PSAS), a validated evaluation tool for linear scars. In addition, patients were asked the "Ultimate Question" (UQ), which correlates with a patient's overall satisfaction. Linear regression models were used to examine differences between surgical approaches with statistical significance set at P<.05. Covariates for all models included patient demographics, length of stay, and surgeon. RESULTS In total, 212 surveys were returned (SILA, 122; LA, 41; OA, 49) for a response rate of 37%. Regression models demonstrated significantly higher mean total PSAS scores for patients who underwent SILA and laparoscopic appendectomy (LA) appendectomy procedures compared with the open procedure (SILA, 8.70; LA, 8.86; OA, 8.01; β=-0.21, P<.05). Patients who experienced the SILA and LA procedures reported significantly higher mean UQ scores compared with OA (SILA, 9.79; LA, 9.75; OA, 9.39; β=-0.22, P<.05). SILA patients reported a 10 on the UQ significantly more often (91.1%) compared with either LA (81%) or OA (75.5%) (P<.05). CONCLUSIONS SILA or LA appendectomy was associated with significantly increased cosmetic satisfaction by patients and their families when compared with OA. This is the first study to show that pediatric patients value attempts to minimize scarring with laparoscopic surgery. Further studies are needed to determine if specific patient factors influence satisfaction with scars.

Abstract
PURPOSE Although a national guideline has been implemented, the optimal approach for appendectomy in children remains subject of debate in the Netherlands. Opponents of laparoscopy raise their concerns regarding its use in complex appendicitis as it is reported to be associated with an increased incidence of intra-abdominal abscesses. The aim of this study was to evaluate the outcome of surgical approaches in both simple and complex appendicitis in paediatric patients. METHODS A 10-year retrospective cohort study was performed (2001-2010) in paediatric patients treated for suspected acute appendicitis. Patients were divided into either simple or complex appendicitis and into different age groups. Primary outcome parameters were complication rate (intra-abdominal abscess (IAA), superficial surgical site infection (SSI) and readmission) and hospital stay. RESULTS In total, 878 patients have been treated (median age 12, range 0-17 years). Two-thirds of the patients younger than 6 years had complex appendicitis, compared to one quarter in the group aged 13-18. In the complex appendicitis group, LA was associated with more IAA and early readmissions. In the simple appendicitis group, the complication rate was comparable between the two approaches. Significantly more IAAs were seen after LA in the youngest age group. CONCLUSION This study demonstrates the unfavourable outcome of LA in the youngest age group and in patients with complex appendicitis. Therefore, we advise to treat these patients with an open approach.

Abstract
BACKGROUND The advent of laparoscopic surgery has facilitated the management of acute appendicitis in the adult population. In the paediatric population (<12 years), management varies according to institution and/or consultant expertise. The aim of this study was to analyse consultant preference for laparoscopic versus open appendicectomy in the management of acute appendicitis in children under 12 years presenting to general hospitals. METHODS A 15-point questionnaire was distributed to 81 consultant surgeons identified from the specialist register of the Irish Medical Council and practicing as general surgeons outside of specialist paediatric centres. RESULTS A response rate of 83 % (67/81) was obtained. Of the 67 surgeons surveyed, 11 (16 %) had formal paediatric training. Sixty percent (40/67) of surgeons expressed a preference for the open technique. The median frequency of on-call rota was >1 in 5 (32/67) and only 3 % (2/67) claimed that the on-call commitment influenced decision-making regarding surgical approach. The average minimum age (9.3 years, range 1-14) and average minimum weight (25 kg, range 12-70) at which the operating surgeon would perform a laparoscopic appendicectomy were also recorded. Thirty percent (20/67) of consultant general surgeons had immediate access to specialist paediatric laparoscopic equipment. DISCUSSION This study has shown wide variability amongst consultant general surgeons when considering open versus laparoscopic appendicectomy in children under 12 years. Restricted access to specialist paediatric laparoscopic equipment, combined with declining exposure to paediatric surgical training, may continue to limit the numbers of paediatric laparoscopic appendicectomies performed in the general setting.

Abstract
Introduction Despite the increase in use of laparoscopic appendectomy (LA) in recent years, until now no nationwide survey on this issue has been performed in Poland. Aim To determine current surgical practice patterns among Polish pediatric surgeons in the treatment of appendicitis in children. Material and methods The nationwide survey was conducted in the form of an internet questionnaire asking for information concerning treatment of children suspected of having acute appendicitis in the years 2007–2011. Twenty-seven major pediatric surgical departments in Poland were invited to participate in the study. Results The overall survey response rate was 70.37%. Laparoscopic appendectomy was offered in all departments except one. Laparoscopy was used in 33% of cases and was the standard procedure in 4 departments. In 1 center 100% of appendectomies were performed laparoscopically. The 3-port technique was used in all departments. Five centers offered transumbilical laparoscopic extracorporeal appendectomy and 2 centers single-port appendectomy. In LA the mesoappendix was mostly divided using bipolar or monopolar coagulation and the appendix was ligated using endoloops or was clipped. The mean hospitalization time was 3.31 days after laparoscopy and 5.47 days after open appendectomy. Conclusions Despite an apparent consensus on some aspects of pediatric appendicitis among Polish pediatric surgeons, significant inconsistency exists in the operative approach. The low rate of LA suggests that LA still remains far from being a standard. Personal experience and preference have a major influence on the choice of operative approach. It is recommended that national guidelines be set up, which could standardize the care for children and training of pediatric surgery residents.

BACKGROUND The aim of this meta-analysis was to determine the effect of laparoscopic appendectomy (LA) compared to open appendectomy (OA) on short-term and long-term post-operative bowel obstruction. METHODS Medline, Embase, trial registries, conference proceedings and reference lists were searched. Subset analysis was performed for paediatric patients, patients who presented with perforated appendicitis and studies with long-term follow-up and surveillance for bowel obstruction and with surgery for bowel obstruction. RESULTS Overall, 29 studies comprising 159,729 patients (60,875 LA versus 98,854 OA) were included. LA was associated with a significant reduction in the incidence of post-operative bowel obstruction in the general population (pooled odds ratio (POR) = 0.43 [95 %C.I. 0.3-0.63]). Subset analysis demonstrated that LA significantly reduced the incidence of post-operative bowel obstruction in paediatric patients (POR = 0.48 [95 %C.I. 0.3-0.78]) and patients with perforated appendicitis (POR = 0.44 [95 %C.I. 0.26-0.74]). Furthermore, LA was associated with a significantly reduced incidence of long-term bowel obstruction (POR = 0.33 [95 %C.I. 0.19-0.56]) and bowel obstruction requiring surgery (POR = 0.31 [95 %C.I. 0.2-0.48]). DISCUSSIONS This present meta-analysis provides evidence to clearly demonstrate the benefits of a laparoscopic approach to appendectomy as reflected by a reduction in short- and long-term adhesive bowel obstruction. Important future areas for assessment include the influence of surgical approach on long-term quality of life following appendectomy.

Abstract
AIM: To introduce a new strategy during complicated open appendectomy - converting open operation to laparoscopy.
METHODS: We retrospectively reviewed databases at two institutions between October 2010 and January 2013, identifying 826 patients who had undergone complicated appendectomy for histologically confirmed acute or chronic appendicitis. They included 214 complicated appendectomies: 155 lengthened-incision open appendectomies (LIA group) and 59 open appendectomies with conversion to laparoscopy (OACL group).
RESULTS: A total of 214 patients with complicated appendectomies were included in the study, including 155 cases of LIA and 59 cases of OACL. No major complication leading to death occurred in the study. Patient characteristics of the two groups were similar. Several parameters showed a significant difference between the two groups. For the OACL vs LIA groups they were, respectively: incision length (3.8 ± 1.4 cm vs 6.2 ± 3.5 cm, P < 0.05); time to flatus recovery (2.3 ± 0.6 d vs 4.2 ± 0.8 d, P < 0.05), drainage rate (61.0% vs 80.0%, P < 0.05); pain level (3.6 ± 1.8 vs 7.2 ± 2.4, P < 0.05); hospital stay (5.1 ± 2.7 d vs 8.7 ± 3.2 d, P < 0.05); complication rate (8.5% vs 14.7%, P < 0.05). Other factors showed no significant differences.
CONCLUSION: Lengthened-incision open appendectomy increases the incidence of complications and prolongs the hospital stay. Conversion of open to laparoscopic appendectomy is feasible and efficient in complicated cases. It decreases the rate of incisional and abdominal infections, allows faster return of bowel movements, and shortens the hospital stay.

Abstract
Abstract
Background
Laparoscopic appendicectomy has been proposed as the standard for surgical treatment of acute appendicitis, based on controversial evidence. This study compared outcomes after open and laparoscopic appendicectomy in a national, population-based cohort.
Methods
All patients who underwent open or intended laparoscopic appendicectomy in Sweden between 1992 and 2008 were identified from the Swedish National Patient Register. The outcomes were analysed according to intention to treat with multivariable adjustment for confounding factors and survival analytical techniques where appropriate.
Results
A total of 169 896 patients underwent open (136 754) or intended laparoscopic (33 142) appendicectomy. The rate of intended laparoscopic appendicectomy increased from 3·8 per cent (425 of 11 175) in 1992 to 32·9 per cent (3066 of 9329) in 2008. Laparoscopy was used most frequently in middle-aged patients, women and patients with no co-morbidity. The rate of conversion from laparoscopy to open appendicectomy decreased from 75·3 per cent (320 of 425) in 1992 to 19·7 per cent (603 of 3066) in 2008. Conversion was more frequent in women and those with perforated appendicitis, and the rate increased with age and increasing co-morbidity. After adjustment for co-variables, compared with open appendicectomy, laparoscopy was associated with a shorter length of hospital stay (by 0·06 days), a lower frequency of negative appendicectomy (adjusted odds ratio (OR) 0·59; P < 0·001), wound infection (adjusted OR 0·54; P = 0·004) and wound rupture (adjusted OR 0·44; P = 0·010), but higher rates of intestinal injury (adjusted OR 1·32; P = 0·042), readmission (adjusted OR 1·10; P < 0·001), postoperative abdominal abscess (adjusted OR 1·58; P < 0·001) and urinary infection (adjusted OR 1·39; P = 0·020). Laparoscopy had a lower risk of postoperative small bowel obstruction during the first 2 years after surgery, but not thereafter.
Conclusion
The outcomes of laparoscopic and open appendicectomy showed a complex and contrasting pattern and small differences of limited clinical importance. The choice of surgical method therefore depends on the local situation, the surgeon's experience and the patient's preference.

Abstract
AIMS The aim of this study was to evaluate the potential role of laparoscopic appendicectomy in reducing morbidity and length of stay in children compared to open procedures in a UK District General Hospital setting. METHODS A three-year retrospective review of children ≤ 15 years with histologically confirmed appendicitis who underwent laparoscopic (LA) and/or open (OA) appendicectomy was performed. Choice of operation was based on individual surgeon's preference and on patient's body size. Data collected included rate of histologically complicated appendicitis, post-operative length of stay (LOS), and collective and differential morbidity rates, i.e., wound infection, intra-abdominal collection, and ileus. Chi-square and Mann-Whitney tests were used for statistical analysis. P<0.05 was regarded as significant. RESULTS Eighty children (70% male) were identified at median age 11 (3-15) years. They could be divided into complicated (n=18, 22%) and simple appendicitis (n=62, 78%). Appendicectomy was performed in all as an OPEN (n=53, 66%) or LAPAROSCOPIC (n=27, 34%) procedure. Both groups were comparable in gender distribution (P=0.11) and rate of complicated appendicitis (30% vs. 19%, respectively; P=0.27). Median age was significantly lower in the OPEN group [10 (3-15) vs. 12 (7-15) years; P<0.004]. Laparoscopic appendicectomy had a significantly lower rate of collective morbidity (3.8% vs. 25.9%; P<0.003), including lower rate of intra-abdominal collection (1.9% vs. 14.8%; P<0.01). Median LOS was not significantly different (1 day vs. 2 days; P=0.14). CONCLUSION Laparoscopic appendicectomy in children in a UK District General Hospital is safe and was associated with significantly less post-operative morbidity than the open technique.

Patient and parental scar assessment after single incision versus standard 3-port laparoscopic appendectomy: long-term follow-up from a prospective randomized trial. J Pediatr Surg 2014; 49:120-2; discussion 122. [PMID: 24439594 DOI: 10.1016/j.jpedsurg.2013.09.041] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2013] [Accepted: 09/30/2013] [Indexed: 11/23/2022]
Abstract
BACKGROUND Single site laparoscopy for appendectomy is a technique with several case series suggesting a cosmetic advantage, but without prospective comparative data. We conducted a prospective, randomized trial comparing single site laparoscopic appendectomy to the standard 3-port approach, including scar assessment at early and long-term follow-up. METHODS Enrolled patients over 12years old and parents of patients less than 12years old were asked to complete the validated Patient Scar Assessment Questionnaire (PSAQ) at early follow-up around 6weeks and by phone after 18months. The PSAQ consists of 4 scored subscales: Appearance, Consciousness, Appearance Satisfaction, and Symptom Satisfaction. Each subscale has a set of questions with a 4-point categorical response (1=most favorable, 4=least favorable). The sum of the scores quantifies each subscale. RESULTS Early questionnaires were obtained from 98 3-port and 100 single-site patients with the single-site approach producing superior overall scar assessment (P=0.003). By telephone follow-up, questionnaires were completed by 49 3-port and 56 single-site patients at a median of 25 (18-32) months. In this longer-term follow-up, overall scar assessment was not significantly different between groups (P=0.06). CONCLUSION Patients or parents express superior scar assessment with the single site approach at early follow-up, but this difference disappears in the long-term.

Abstract
BACKGROUND A primary determinant of value in treating appendicitis is inpatient cost. The purpose of this study was to identify hospital-level factors that drive costs associated with the treatment of appendicitis. METHODS Cost-to-charge ratios from the 2009 Kids' Inpatient Database gave average all-payer costs by hospital for uncomplicated appendicitis (without peritonitis, ICD-9-CM 540.9) and complicated appendicitis (generalized peritonitis, 540.0; peritoneal abscess, 540.1). The 10% of hospitals with the lowest costs were defined as low cost; the remaining 90% were defined non-low cost. Bivariate and multivariate analyses compared hospital characteristics between the two groups. RESULTS Threshold cost dividing low cost from non-low cost for uncomplicated appendicitis was $4626; for complicated appendicitis, it was $6,026. For both conditions teaching status, lower percentage of pediatric discharges, and fewer registered nurses (RN) per 1000 adjusted patient-days predicted a hospital to be low cost. A cost benefit for medium and large hospitals and higher inpatient volume was found only for uncomplicated appendicitis. Regional effects were noted. CONCLUSIONS The findings show the high-cost structure of hospitals that care for high volumes of children, emphasizing the need to constrain cost. There is some benefit of economies of scale, and careful attention to the numbers of nursing personnel.
