Management of Gastroschisis: Timing of Delivery, Antibiotic Usage, and Closure Considerations (A Systematic Review From the American Pediatric Surgical Association Outcomes & Evidence Based Practice Committee).

BACKGROUND: No consensus exists for the initial management of infants with gastroschisis. METHODS: The American Pediatric Surgical Association (APSA) Outcomes and Evidenced-based Practice Committee (OEBPC) developed three a priori questions about gastroschisis for a qualitative systematic review. We reviewed English-language publications between January 1, 1970, and December 31, 2019. This project describes the findings of a systematic review of the three questions regarding: 1) optimal delivery timing, 2) antibiotic use, and 3) closure considerations. RESULTS: 1339 articles were screened for eligibility; 92 manuscripts were selected and reviewed. The included studies had a Level of Evidence that ranged from 2 to 4 and recommendation Grades B-D. Twenty-eight addressed optimal timing of delivery, 5 pertained to antibiotic use, and 59 discussed closure considerations (Figure 1). Delivery after 37 weeks post-conceptual age is considered optimal. Prophylactic antibiotics covering skin flora are adequate to reduce infection risk until definitive closure. Studies support primary fascial repair, without staged silo reduction, when abdominal domain and hemodynamics permit. A sutureless repair is safe, effective, and does not delay feeding or extend length of stay. Sedation and intubation are not routinely required for a sutureless closure. CONCLUSIONS: Despite the large number of studies addressing the above-mentioned facets of gastroschisis management, the data quality is poor. A wide variation in gastroschisis management was documented, indicating a need for high quality RCTs to provide an evidence-based approach when caring for these infants. TYPE OF STUDY: Qualitative systematic review of Level 1-4 studies.

Surgical Management of Ulcerative Colitis in Children and Adolescents: A Systematic Review from the APSA Outcomes and Evidence-Based Practice Committee.

INTRODUCTION: The incidence of ulcerative colitis (UC) is increasing. Roughly 20% of all patients with UC are diagnosed in childhood, and children typically present with more severe disease. Approximately 40% will undergo total colectomy within ten years of diagnosis. The objective of this study is to assess the available evidence regarding the surgical management of pediatric UC as determined by the consensus agreement of the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee (APSA OEBP). METHODS: Through an iterative process, the membership of the APSA OEBP developed five a priori questions focused on surgical decision-making for children with UC. Questions focused on surgical timing, reconstruction, use of minimally invasive techniques, need for diversion, and risks to fertility and sexual function. A systematic review was conducted, and articles were selected for review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Risk of Bias was assessed using Methodological Index for Non-Randomized Studies (MINORS) criteria. The Oxford Levels of Evidence and Grades of Recommendation were utilized. RESULTS: A total of 69 studies were included for analysis. Most manuscripts contain level 3 or 4 evidence from single-center retrospective reports, leading to a grade D recommendation. MINORS assessment revealed a high risk of bias in most studies. J-pouch reconstruction may result in fewer daily stools than straight ileoanal anastomosis. There are no differences in complications based on the type of reconstruction. The timing of surgery should be individualized to patients and does not affect complications. Immunosuppressants do not appear to increase surgical site infection rates. Laparoscopic approaches result in longer operative times but shorter lengths of stay and fewer small bowel obstructions. Overall, complications are not different using an open or minimally invasive approach. CONCLUSIONS: There is currently low-level evidence related to certain aspects of surgical management for UC, including timing, reconstruction type, use of minimally invasive techniques, need for diversion, and risks to fertility and sexual function. Multicenter, prospective studies are recommended to better answer these questions and ensure the best evidence-based care for our patients. LEVEL OF EVIDENCE: Level of evidence III. STUDY TYPE: Systematic review.

A Rare Case of Colonic Triplication with Associated Imperforate Anus in a Newborn Male.

We present a case of a newborn male with imperforate anus who was found to have colonic triplication with a high rectovesical fistula. The case is presented with a focus on surgical strategies for the management of this rare malformation.

Predictors of length of stay for simple gastroschisis: analysis of ACS NSQIP-P database.

PURPOSE: We aimed to assess predictors of length of stay for simple gastroschisis utilizing the NSQIP-Pediatric Database. METHODS: The NSQIP-P Participant Use Data File was queried to identify patients with simple gastroschisis. We defined short length of stay (LOS) as patients discharged home ≤ 30 days from birth. We compared patients with short LOS versus prolonged LOS > 30 days. Predictors and outcomes were evaluated. RESULTS: There were 888 patients with simple gastroschisis identified. Half of patients had LOS ≤ 30 days. Patients with LOS ≤ 30 were younger at repair (median age 1 day vs. 3 days, p = 0.0001), had higher birth weight (median 2.5 kg vs. 2.4 kg, p = 0.0001), and were less premature (37 week vs. 36 weeks, p = 0.0001). However, only gestational age and weight at birth were significant predictors of LOS on multivariate analysis (p = 0.0001). Prolonged LOS patients had more instances of ventilation, oxygen supplementation, sepsis (n = 2/446 or 0.4% vs. n = 9/442 or 2%, p = 0.003), bleeding/transfusion (n = 7/446 or 1.6% vs. n = 43/442 or 9.7%, p = 0.0001), line infections (n = 1/446 or 0.2% vs. n = 12/442, p = 0.001), and reoperations (n = 9/446 or 2% vs. n = 26/442 or 5.9%, p = 0.003). CONCLUSION: Prematurity and birth weight are significant predictors of length of stay in simple gastroschisis patients. Prenatal counseling should continue to be one of the main factors to improve the outcomes for patients with gastroschisis. Type of study Retrospective cohort study. Level of evidence Level IV.

Pneumomediastinum: A Rare Presentation of Inflicted Injuries in Infants.

Reports of incidental pneumomediastinum in infants secondary to inflicted trauma are limited. A retrospective review of infants with pneumomediastinum and history of inflicted trauma was performed. A comprehensive literature review was performed. Three infants presented with pneumomediastinum associated with inflicted trauma. Mean age was 4.6 weeks. All patients underwent diagnostic studies, as well as a standardized evaluation for nonaccidental trauma. All patients with pneumomediastinum were resolved at follow-up. Review of the literature identified other cases with similar presentations with related oropharyngeal injuries. Spontaneous pneumomediastinum in previously healthy infants may be associated with inflicted injuries. Clinicians should be aware of the possibility of an oropharyngeal perforation related to this presentation.

To Button or Not to Button? Primary Gastrostomy Tubes Offer No Significant Advantage Over Buttons.

Purpose: Outcomes between primary gastrostomy tubes and buttons (G-tube and G-button) have not been established in pediatric patients. We hypothesized that primary G-tube have decreased complications when compared to G-button. Methods: A retrospective review of surgically placed gastrostomy devices from 2010 to 2017 was performed. Data collected included demographics, outcomes and 90-day complications. We divided the patients into primary G-tube and primary G-button. Results: Of 265 patients, 142 (53.6%) were male. Median age and weight at the time of surgery were 7 months (interquartile range [IQR], 2-44 months) and 6.70 kg (IQR, 3.98-14.15 kg), respectively. Among the groups, G-tube had 80 patients (30.2%) while G-button 185 patients (69.8%). There were 153 patients with at least one overall complication within 90 days postoperative. There was no significant difference in overall complications between groups (G-tube 63.8% vs. G-button 55.7%, p=0.192). More importantly, there were no significant differences in major complications among the groups, G-tube vs. G-button (5% vs. 4%; p=0.455). Conclusion: Primary G-tube offers no significant advantage in overall, minor or major complications when compared to primary G-button.

Protocolized management of pediatric complicated appendicitis leads to improved outcomes.

PURPOSE: We aimed to evaluate a complicated appendicitis clinical practice guideline at our institution. METHODS: Records were compared before and after protocol implementation. We standardized an ED consult pathway, antibiotic use and need for early appendectomy (EA) versus interval appendectomy (IA). We evaluated demographics, clinical characteristics, and outcomes. Subgroup analysis was performed to compare patients with small abscess treated with IA pre-protocol versus similar patients treated by EA post-protocol. RESULTS: In total 246 patients were reviewed (Pre-protocol = 152, Post-protocol = 94). Pre-protocol early appendectomy rate was 51% versus 82% on post-protocol patients. There were no differences in demographics. Post-protocol the use of preoperative imaging significantly decreased (Pre 92% vs. 56%, p = 0.0001), as well as the use of discharge antibiotics (Pre 93% vs. Post 27%, p = 0.0001) with no change in abscess rate. Overall, post-protocol patients had fewer total CT scans performed (Pre 40% vs. Post 28%, p = 0.03) and decreased total length of stay (Pre 7.7 vs. Post 6.5 days, p = 0.049). On subgroup analysis, post-protocol EA with no or small abscess had lower median number of admissions, decreased total LOS (Pre IA 9 days vs. Post EA 5 days, p = 0.00001) and fewer complications (Pre IA 42% vs. EA 22%, p = 0.022). CONCLUSION: The establishment of a standardized pediatric complicated appendicitis protocol may lead to improved outcomes and resource utilization. Patients presenting with no or small abscess may be the least likely to benefit from interval appendectomy. LEVEL OF EVIDENCE: Level III.

Management of the undescended testis in children: An American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee Systematic Review.

PURPOSE: Management of undescended testes (UDT) has evolved over the last decade. While urologic societies in the United States and Europe have established some guidelines for care, management by North American pediatric surgeons remains variable. The aim of this systematic review is to evaluate the published evidence regarding the treatment of (UDT) in children. METHODS: A comprehensive search strategy and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Five principal questions were asked regarding imaging standards, medical treatment, surgical technique, timing of operation, and outcomes. A literature search was performed from 2005 to 2020. RESULTS: A total of 825 articles were identified in the initial search, and 260 were included in the final review. CONCLUSIONS: Pre-operative imaging and hormonal therapy are generally not recommended except in specific circumstances. Testicular growth and potential for fertility improves when orchiopexy is performed before one year of age. For a palpable testis, a single incision approach is preferred over a two-incision orchiopexy. Laparoscopic orchiopexy is associated with a slightly lower testicular atrophy rate but a higher rate of long-term testicular retraction. One and two-stage Fowler-Stephens orchiopexy have similar rates of testicular atrophy and retraction. There is a higher relative risk of testicular cancer in UDT which may be lessened by pre-pubertal orchiopexy.

Index Admission Cholecystectomy and Recurrence of Pediatric Gallstone Pancreatitis: Multicenter Cohort Analysis.

BACKGROUND: We aim to evaluate recurrence rates of gallstone pancreatitis in children undergoing early vs interval cholecystectomy. STUDY DESIGN: A multicenter, retrospective review of pediatric patients admitted with gallstone pancreatitis from 2010 through 2017 was performed. Children were evaluated based on timing of cholecystectomy. Early cholecystectomy was defined as surgery during the index admission, whereas the delayed group was defined as no surgery or surgery after discharge. Outcomes, recurrence rates, and complications were evaluated. RESULTS: Of 246 patients from 6 centers with gallstone pancreatitis, 178 (72%) were female, with mean age 13.5 ± 3.2 years and a mean body mass index of 28.9 ± 15.2. Most (90%) patients were admitted with mild pancreatitis (Atlanta Classification). Early cholecystectomy was performed in 167 (68%) patients with no difference in early cholecystectomy rates across institutions. Delayed group patients weighed less (61 kg vs. 72 kg, p = 0.003) and were younger (12 vs. 14 years, p = 0.001) than those who underwent early cholecystectomy. However, there were no differences in clinical, radiological, or laboratory characteristics between groups. There were 4 (2%) episodes of postoperative recurrent pancreatitis in the early group compared with 22% in the delayed group. More importantly, when cholecystectomy was delayed more than 6 weeks from index discharge, recurrence approached 60%. There were no biliary complications in any group. CONCLUSIONS: Cholecystectomy during the index admission for children with gallstone pancreatitis reduces recurrent pancreatitis. Recurrence proportionally increases with time when patients are treated with a delayed approach.

Pediatric Peritoneal Dialysis Catheter Placement: An Anonymous Survey of APSA Members.

BACKGROUND: Although literature is sparse, there are guidelines regarding optimal placement technique for peritoneal dialysis (PD) catheters in the pediatric population. Through this study, we sought to identify commonly used techniques among pediatric surgeons and identify areas for future work. MATERIALS AND METHODS: A 16-question anonymous survey was emailed to American Pediatric Surgery Association members in September 2018 regarding routine practices for PD catheter placement. Descriptive statistics and Fisher's exact test were used for analysis. RESULTS: In all, there were 221 respondents, 6.8% of whom did not place PD catheters in their practice. Of the remaining 206, the majority have been in practice >15 y. PD catheter placement during fellowship training varied widely, with 6.5% reporting no fellowship experience to 6% reporting >25 placed during fellowship. Almost half (48%) reported placing catheters via laparoscopic approach (versus open or combined approach). Most (62%) respondents reported an annual practice volume of 1-5 catheters, with only 11% placing >10 per year. Exit-site sutures were placed "always" by 33% of participants and "never" by 49% of participants. There was no association between years in practice or fellowship experience and exit-site suture placement. However, there was a trend for "never" placement (72%) with more recent graduates. Omentectomy was performed by 91% of respondents, whereas 8.3% reported never performing omentectomy/omentopexy. Similarly, there was no association between practice and fellowship experience and omentectomy. In the setting of abdominal stoma, 96% reported placing the exit site on the opposite side of the abdomen. Fibrin glue was used along the tunnel by 21% of participants, ranging from "always" to "sometimes", whereas 79% "never" used it. CONCLUSIONS: Fellowship, posttraining experience, and techniques in PD catheter placement vary widely among American Pediatric Surgery Association member respondents. Despite guidelines, practices differ among providers without an association between the number of cases performed in fellowship and postfellowship volume.

Screening Laboratory Testing in Asymptomatic Minor Pediatric Blunt Trauma Leads to Unnecessary Needle Sticks.

OBJECTIVE: Screening blood work after minor injuries is common in pediatric trauma. The risk of missed injuries versus diagnostic necessity in an asymptomatic patient remains an ongoing debate. We evaluated the clinical utility of screening blood work in carefully selected asymptomatic children after minor trauma. METHODS: Patients seen at a level 1 pediatric center with "minor trauma" for blunt trauma between 2010 and 2015 were retrospectively reviewed. Exclusion criteria were age <4 of >18 years, a Glasgow Coma Scale score of <15, penetrating trauma, nonaccidental trauma, hemodynamic instability, abdominal findings (pain, distension, bruising, tenderness), hematuria, pelvic/femur fracture, multiple fractures, and operative intervention. Data abstraction included demographics, blood work, interventions, and disposition. RESULT: A total of 1308 patients were treated during the study period. Four hundred thirty-three (33%) met inclusion criteria. Mean ± SD age was 12.7 ± 4 years (range, 4-18 years), and 59% were male. Seventy-eight percent were discharged home from the emergency department. All patients had blood work. Twenty-eight percent had at least one abnormal laboratory value. The most common abnormal blood work was leukocytosis (16%). Thirty percent had an intervention, and none prompted by abnormal blood work. One patient had an intra-abdominal finding (psoas hematoma). CONCLUSION: When appropriately selected, screening laboratory testing in asymptomatic minor pediatric blunt trauma patients leads to unnecessary needle sticks without significant advantage.

To operate or not to operate? Assessing NSQIP surgical outcomes in trisomy 18 patients.

BACKGROUND: Trisomy 18 is associated with a wide range of potentially fatal congenital conditions. Historically, clinical attitudes on treatment have been ambiguous, with palliative care as the standard of care. The aim of our study was to provide a descriptive analysis of surgical outcomes in patients with trisomy 18. STUDY DESIGN: We identified patients with trisomy 18 aged 0-18 years using the NSQIP-Pediatric database from 2012 to 2017 and analyzed demographics, surgery types, and perioperative characteristics of patients with trisomy 18 patients undergoing surgical intervention. Additionally, a case-match analysis was performed to assess surgical outcome differences. RESULTS: A total of 310 patients with trisomy 18 were identified. Thirty-one percent were >5 years of age and 73% were female. The most common surgical types were general surgery procedures (57.4%), followed by orthopedics (18.1%) and ENT (10.3%). Operations performed increased from 8% (2012) to 26% (2017), and only 23% of patients had previous cardiac surgery. Majority of patients had no prior history of malignancy (95%) and 5% had a tracheostomy placed. Discharge to home was achieved in 74% of patients, with a median total hospital length of stay of 5 days (IQR 17). Furthermore, 90% survived over 30 days from the operation. Thirty-two patients had readmissions and the most common reasons were dehydration, gastrostomy infection or malfunction. Surgical site infections occurred in <3% of patients. No differences in complications, length of stay, reoperations, and readmissions were identified by case-match analysis. CONCLUSION: In this data set, patients with trisomy 18 undergoing noncardiac surgical procedures experience excellent surgical outcomes with minimal morbidity and low mortality. Most patients more than a year of age will experience similar outcomes to patients without trisomy 18. TYPE OF STUDY: Treatment study (retrospective comparative study) LEVEL OF EVIDENCE: Level III.

Open Gastrostomy Tube Placement is Associated With Higher Complications in Infants: A National Surgical Quality Improvement Program Database Analysis.

BACKGROUND: The purpose of this study was to compare outcomes between open versus laparoscopic gastrostomies in children aged ≤1 y. METHODS: The American College of Surgeons' National Surgical Quality Improvement Program Pediatric database was reviewed between 2012 and 2017. Chi-square analysis was performed on children aged ≤1 y to compare complication rates between open and laparoscopic procedures. RESULTS: A total of 7940 patients were aged ≤1 y. Of which, 20% underwent open gastrostomy (OGT), and 80% received laparoscopic gastrostomy (LGT). There were no differences in sex or race. However, OGT patients were younger (119 d versus 134 d; P = 0.0001), smaller at birth (1.84 kg versus 1.85 kg; P = 0.03), and were smaller at operation (4.6 kg versus 5 kg; P = 0.0001). Also, patients were more likely to be inpatient at the time of surgery and had more congenital malformations. Complications (OGT 6% versus LGT 4%; P = 0.001) and mortality were significantly higher in the open group (OGT 2.3% versus LGT 0.6%; P = 0.001). However, matched control analysis demonstrated OGT patients have more complications. CONCLUSIONS: OGT patients are smaller and with more significant comorbidities in this data set. In fact, even after matched control analysis, these patients experience more complications.

Impaired Gut-Systemic Signaling Drives Total Parenteral Nutrition-Associated Injury.

BACKGROUND: Total parenteral nutrition (TPN) provides all nutritional needs intravenously. Although lifesaving, enthusiasm is significantly tempered due to side effects of liver and gut injury, as well as lack of mechanistic understanding into drivers of TPN injury. We hypothesized that the state of luminal nutritional deprivation with TPN drives alterations in gut-systemic signaling, contributing to injury, and tested this hypothesis using our ambulatory TPN model. METHODS: A total of 16 one-week-old piglets were allocated randomly to TPN (n = 8) or enteral nutrition (EN, n = 8) for 3 weeks. Liver, gut, and serum were analyzed. All tests were two-sided, with a significance level of 0.05. RESULTS: TPN resulted in significant hyperbilirubinemia and cholestatic liver injury, p = 0.034. Hepatic inflammation (cluster of differentiation 3 (CD3) immunohistochemistry) was higher with TPN (p = 0.021). No significant differences in alanine aminotransferase (ALT) or bile ductular proliferation were noted. TPN resulted in reduction of muscularis mucosa thickness and marked gut atrophy. Median and interquartile range for gut mass was 0.46 (0.30-0.58) g/cm in EN, and 0.19 (0.11-0.29) g/cm in TPN (p = 0.024). Key gut-systemic signaling regulators, liver farnesoid X receptor (FXR; p = 0.021), liver constitutive androstane receptor (CAR; p = 0.014), gut FXR (p = 0.028), G-coupled bile acid receptor (TGR5) (p = 0.003), epidermal growth factor (EGF; p = 0.016), organic anion transporter (OAT; p = 0.028), Mitogen-activated protein kinases-1 (MAPK1) (p = 0.037), and sodium uptake transporter sodium glucose-linked transporter (SGLT-1; p = 0.010) were significantly downregulated in TPN animals, whereas liver cholesterol 7 alpha-hydroxylase (CyP7A1) was substantially higher with TPN (p = 0.011). CONCLUSION: We report significant alterations in key hepatobiliary receptors driving gut-systemic signaling in a TPN piglet model. This presents a major advancement to our understanding of TPN-associated injury and suggests opportunities for strategic targeting of the gut-systemic axis, specifically, FXR, TGR5, and EGF in developing ameliorative strategies.

Development and validation of an ambulatory piglet model for short bowel syndrome with ileo-colonic anastomosis.

IMPACT STATEMENT: Short bowel syndrome is associated with significant comorbidities and mortality. This study is important as unlike current systems, it provides a validated piglet model which mirrors anatomical, histological, and serological characteristics observed in human SBS. This model can be used to advance knowledge into mechanistic pathways and therapeutic modalities to improve outcomes for SBS patients. This study is novel in that in addition to significant reduction in the remnant bowel and noted liver disease, we also developed a method to emulate ileocecal valve resection and described gut adaptive responses which has important clinical implications in humans.

Multicenter retrospective comparison of spontaneous intestinal perforation outcomes between primary peritoneal drain and primary laparotomy.

PURPOSE: The purpose of our study was to compare outcomes of infants with spontaneous intestinal perforation (SIP) treated with primary peritoneal drain versus primary laparotomy. METHODS: We performed a multi-institution retrospective review of infants with diagnosis of SIP from 2012 to 2016. Clinical characteristics and outcomes were compared between infants treated with primary peritoneal drain vs infants treated with laparotomy. RESULTS: We identified 171 patients treated for SIP (drain n = 110 vs. laparotomy n = 61). There were no differences in maternal or prenatal characteristics. There were no clinically significant differences in vital signs, white blood cell or platelet measures, up to 48 h after intervention. Patients who were treated primarily with a drain were more premature (24.9 vs. 27.2 weeks, p < 0.001) and had lower median birth weight (710 g vs. 896 g, p < 0.001). No significant differences were found in complications, time to full feeds, length of stay (LOS) or mortality between the groups. Primary laparotomy group had more procedures (median number 1 vs. 2, p = 0.002). There were 32 (29%) primary drain failures whereby a laparotomy was ultimately needed. CONCLUSIONS: SIP treated with primary drain is successful in the majority of patients with no significant differences in outcomes when compared to laparotomy with stoma. THE LEVEL OF EVIDENCE: III.

Perioperative Antibiotics Are Independent Predictors for Major Complications in Pediatric Patients Undergoing Gastrostomy Placement.

Introduction: Although rare, major complications after gastrostomy tube placement are a significant source of morbidity in children. The purpose of this study was to identify predictors of major complications in pediatric patients undergoing gastrostomy placement. Materials and Methods: Retrospective review of surgically placed gastrostomy tubes from 2010 to 2017 was performed. Data collected included demographics, outcomes, and major complications. We divided the patients into no complications (Group 1) and major complications (Group 2). Excluded were minor complications and percutaneous endoscopic gastrostomy procedures. Results: Of 123 patients, 51.5% were males and 52% infants. Group 1 had 112 patients (91%), whereas Group 2 had 11 patients (9%). Of Group 2 patients, 3 required prolonged nil per os/total parenteral nutrition and 8 surgical reinterventions. Laparoscopy in 110 patients (89%), open surgery in 10 patients (8%), and 3 conversions to open. There were no significant differences in demographics or preoperative characteristics (albumin and comorbidities). We identified surgical approach (open: 6.3% versus 27.3%, P = .014), operative time (58 versus 85 minutes, P = .04), and use of preoperative antibiotics (63% versus 92%, P = .004) as predictors of outcomes. However, on multivariate analysis lack of preoperative antibiotics (adjusted odds ratio [aOR], 14.82 [confidence interval: 2.60-84.34], P = .002), and open procedure (aOR, 6.14 [1.01-37.24], P = .049) were independent predictors of major complications. Conclusion: Most patients with major complications after gastrostomy tube placement require surgical reintervention. Lack of preoperative antibiotics and open procedures are independent predictive factors for major complication in patients undergoing gastrostomy tube placement.

Laparoscopic Peritoneal Dialysis Catheter Placement with Chest Wall Exit Site for Neonate with Stoma.

Neonates requiring peritoneal dialysis (PD) catheters have been shown to have complication rates up to 70%. The presence of a concurrent stoma significantly increases the risk of peritonitis, exit-site infection, and catheter failure. As such, multiple techniques have been proposed to reduce these risks, including a chest wall exit site. In this case, the patient was born with bilateral hypoplastic kidneys and an anorectal malformation, requiring a colostomy soon after birth. At 4 weeks of life, he required placement of a PD catheter for dialysis. Given the high risk of infection, a laparoscopic-assisted PD catheter placement with a chest wall exit remote from the colostomy was performed. This report describes the operative technique including omentectomy, placement of a percutaneous stitch between the catheter cuffs, and fibrin glue injection around the catheter. The patient had no catheter-related infections. Laparoscopic-assisted PD catheter placement with chest wall exit site is a safe alternative in patients with any type of abdominal stoma.

Abscess and symptoms duration upon presentation should guide decision algorithms for early versus interval appendectomy in children.

BACKGROUND: To compare outcomes for complicated appendicitis treated with early versus interval appendectomy and to identify which patients would likely benefit from early appendectomy. METHODS: A retrospective review of complicated appendicitis was performed from 2010 to 2015. Patients were divided into early (EA) versus interval appendectomy (IA) groups. We compared demographics, complications and outcomes. Pearson's Chi square analysis and Student's T test analysis were performed. RESULTS: We identified 316 patients (EA group 53% vs. IA group 47%). Interval appendectomy group had longer symptom duration [IA 3.8 vs. EA 2.3 days (p = 0.0001)], increased leukocytosis [IA 18.7 vs. EA 17.2 (p = 0.008)], more initial abscesses [IA 35% vs. EA 13% (p = 0.0001)], more complications [IA 30% vs. EA 19%, (p = 0.013) and prolonged total length of stay [(LOS), p = 0.009]. Subgroup analysis of all patients revealed 80% of patients presented with ≤3 cm abscess and duration of symptoms (DOS) ≤5 days. Interval appendectomy patients with DOS ≤5 days and or ≤3 cm abscess on admission had no differences in clinical presentation. However, these patients had prolonged total LOS (IA 7.7 vs. EA 6.3 days, p = 0.01) and increased complications (IA 29% vs. EA 19%, p = 0.04). CONCLUSION: The majority of patients with complicated appendicitis in children present with small abscess (≤3 cm) and short symptom duration (≤5 days). This subset of patients might benefit from early appendectomy due to decreased LOS, resource utilization and reduced complications.
