Impact of insertion site on complications in central venous access devices.

PURPOSE: There is still debate over the safest route for the placement of long-term central venous access devices. The aim of this study was to review a large, single-institution experience to determine the impact of access location on peri-operative complications. METHODS: The records of patients undergoing subcutaneous port (SQP) and tunneled catheter insertion over a seven-year period were reviewed. Vein cannulated (subclavian (SCV) versus internal jugular (IJ) vein), and 30-day complications were assessed. Surgical complications included pneumothorax, hemothorax, infections, arrhythmia or malpositioning requiring intervention. RESULTS: A total of 1,309 patients were included (618 SQP, 691 tunneled catheters). The location for insertion was SCV (909, 69.4%) and IJ (400, 30.6%). There were 69 complications (5.2%) (41, 4.5% SCV, 28, 7.0% IJV) including: malpositioning/malfunctioning (SCV 13, 1.4% and IJV 14, 3.0%), pneumothorax (SCV 4, 0.4% and IJV 1, 0.3%), hemothorax (SCV 0 and IJV 1, 0.3%), arrhythmia (SCV 1, 0.1%, and IJV 0), and infection within 30 days of placement (SCV 20, 2.2% and IJ 11, 2.8%). The complication rates were not significantly different based on site (p = 0.080). CONCLUSION: There was no significant difference in complication rates when using the subclavian versus the internal jugular vein as the site for long-term central venous access. LEVEL OF EVIDENCE: III, retrospective comparative study.

Review of Perioperative Prophylactic Antibiotic Use during Laparoscopic Cholecystectomy and Subsequent Surgical Site Infection Development at a Single Children's Hospital.

OBJECTIVES: With the rise of antibiotic resistance, the use of prophylactic preoperative antibiotics (PPA) has been questioned in cases with low rates of surgical site infection (SSI). We report PPA usage and SSI rates after elective laparoscopic cholecystectomy at our institution. MATERIALS AND METHODS: A retrospective review of children younger than 18 years who underwent elective outpatient laparoscopic cholecystectomy between July 2010 and August 2020 was performed. Demographic, preoperative work-up, antibiotic use, intraoperative characteristics, and SSI data were collected via chart review. SSI was defined as clinical signs of infection that required antibiotics within 30 days of surgery. RESULTS: A total of 502 patients met the inclusion criteria; 50% were preoperatively diagnosed with symptomatic cholelithiasis, 47% with biliary dyskinesia, 2% with hyperkinetic gallbladder, and 1% with gallbladder polyp(s). The majority were female (78%) and Caucasian (80%). In total, 60% (n = 301) of patients received PPA, while 40% (n = 201) did not; 1.3% (n = 4) of those who received PPA developed SSI, compared with 5.5% (n = 11) of those who did not receive PPA (p = 0.01). Though PPA use was associated with a 77% reduction in the risk of SSI in multivariate analysis (p = 0.01), all SSIs were superficial. One child required readmission for intravenous antibiotics, while the remainder were treated with outpatient antibiotics. Gender, age, body mass index, ethnicity, and preoperative diagnosis did not influence the likelihood of receiving PPA. CONCLUSION: Given the relatively low morbidity of the superficial SSI, conservative use of PPA is advised to avoid contributing to antibiotic resistance.

A single institution experience with Laparoscopic Hernia repair in 791 children.

INTRODUCTION: There are many described technique to performing laparoscopic inguinal hernia repair in children. We describe our outcomes using a percutaneous internal ring suturing technique. METHODS: A retrospective review of patients under 18 years old who underwent repair between January 2014 - March 2019 was performed. A percutaneous internal ring suturing technique, involving hydro-dissection of the peritoneum, percutaneous suture passage, and cauterization of the peritoneum in the sac prior to high ligation, was used. p < 0.05 was considered significant during the analysis. RESULTS: 791 patients were included. The median age at operation was 1.9 years (IQR 0.37, 5.82). The median operative time for a unilateral repair was 21 min (IQR 16, 28), while the median time for a bilateral repair was 30.5 min (IQR 23, 41). In total, 3 patients required conversion to an open procedure (0.4%), 4 (0.6%) experienced post-operative bleeding, 9 (1.2%) developed a wound infection, and iatrogenic ascent of testis occurred in 10 (1.3%) patients. Twenty patients (2.5%) developed a recurrent hernia. All but two were re-repaired laparoscopically. CONCLUSIONS: The use of percutaneous internal ring suturing for laparoscopic repair of inguinal hernias in the pediatric population is safe and effective with a low rate of complications and recurrence.

Management of pancreatic pseudocysts in pediatric oncology patients.

BACKGROUND: Management of children with pancreatic pseudocysts has historically been adopted from the adult experience where pancreatic pseudocysts greater than 6 cm are unlikely to resolve without intervention. We reviewed the clinical course of pediatric oncology patients with pancreatic pseudocysts. METHODS: A retrospective review of patients treated over a 15-year period was performed. Variables evaluated included cancer type, medications administered, clinical and imaging characteristics of the pancreatic pseudocysts, treatment and outcome. RESULTS: A total of 132 patients with a median age of 13 (IQR, 9-17) years were identified with pancreatitis. Thirty-one (23.5%) patients developed a pancreatic pseudocyst, of which 84% were associated with PEG-asparaginase treatment. The median pseudocyst size was 7.6 (IQR, 4.4-9.9) cm with 59% being greater than 6 cm. Twenty-two (71%) patients with a pancreatic pseudocyst underwent successful conservative management, while only 9 (29%) required procedural intervention including six percutaneous drainage, one of whom recurred and required surgical cyst-enteric drainage. Two other patients had primary surgical cyst-enteric drainage and one patient underwent endoscopic retrograde cholangiopancreatography with stenting. The indication for intervention was worsening pain rather than pseudocyst imaging characteristics, size or serum amylase/lipase. CONCLUSION: Most medication-induced pancreatic pseudocysts in children being treated for cancer, regardless of pseudocyst size, can be managed non-operatively or with transgastric percutaneous drainage. The need for intervention can be safely dictated by patient symptoms. LEVEL OF EVIDENCE: III.

Cholecystitis and hemobilia.

Hemobilia, or hemorrhage into the biliary system, is an unusual cause of gastrointestinal bleeding most commonly seen in accidental or iatrogenic trauma. We present the rare case of a 43-year-old gentleman who presents with an intrahepatic pseudoaneurysm caused by cholecystitis. The management of the hemobilia was technically challenging requiring multiple interventional procedures. We review the pathophysiology and treatment strategies for this rare case of gastrointestinal hemorrhage.

Mediastinal Lymphadenopathy in Children With Histoplasmosis.

BACKGROUND: Mediastinal lymphadenopathy (ML) in children can arise from malignancy, infection, or rheumatic illness among others, and may be found incidentally on imaging or during workup for a variety of symptoms. Our aim was to describe the clinical presentation and natural history of histoplasmosis in children who present to a tertiary care center with ML in an endemic area of the country. METHODS: After institutional review board approval, a retrospective study of all children (aged < 21 y) presenting with proven (positive serologies) or suspected histoplasmosis (negative serologies, negative tuberculosis testing, and benign outcomes in follow-up) over a 5-y period was done. Seventy-four patients were tested; those with another diagnosis (n = 6) or without ML (n = 26) were excluded, for a total cohort of 44 patients. Demographics, clinical presentation, symptoms, laboratory data, treatment course, radiography studies, and inpatient and outpatient visits were examined. RESULTS: Of the 44 patients with ML, 27 had proven histoplasmosis, and 19 had suspected histoplasmosis. The median follow-up by imaging or clinical examination was 6.9 mo (0.3-73.2 mo). Sixteen patients received antifungal therapy with itraconazole, and 15 patients received at least one course of steroids, nearly all for respiratory symptoms; 11 patients (24%) received both. There was no difference in readmission rate (n = 5 versus 2, P = 0.7) or recurrence of symptoms (n = 2 versus 5, P = 0.4) between patients who received an antifungal and those that did not. Receiving steroid therapy was associated with airway narrowing and a higher readmission rate (n =6 versus 2 who were not treated with steroids, P = 0.04), but not with symptom recurrence. Nine lymph node or mass biopsies were performed; however, the pathology only confirmed nonspecific infection in three and was nondiagnostic in the remaining six patients. Twenty-seven patients had at least one confirmatory laboratory test positive for histoplasmosis. Thirty-nine of the 44 patients (84%) with a diagnosis of histoplasmosis (proven or suspected) were asymptomatic by 1-2 mo follow up, with the remainder having intermittent chest pain or reactive airway disease. CONCLUSIONS: ML because of proven or suspected histoplasmosis is usually a self-limiting disease that can be managed with treatment of the child's symptoms. Antifungals and steroids are of unclear benefit and may not alter the natural course of the disease. Biopsies are rarely diagnostic in the setting of ML, and invasive procedures should be avoided.

In-hospital Pediatric Endoscopic Retrograde Cholangiopancreatography Is Associated With Shorter Hospitalization for Children With Choledocholithiasis.

OBJECTIVES: Children with choledocholithiasis are frequently managed at tertiary children's hospitals that do not have available endoscopic retrograde cholangiopancreatography (ERCP) proceduralists. We hypothesized that patients treated at hospitals without ERCP proceduralists would have a longer hospital length of stay (LOS) than those with ERCP proceduralists. METHODS: Charts were reviewed for patients who underwent cholecystectomy and ERCP at 3 tertiary children's hospitals over 10 years. Trauma and complicated pancreatitis patients were excluded. Comparisons between patients requiring and not requiring transfer for ERCP were made using Wilcoxon rank-sum tests for continuous variables and Fisher's exact tests for categorical variables. RESULTS: One hundred and sixty-four children underwent ERCP for suspected choledocholithiasis: 79 (48%) in the transfer group and 85 (52%) in the no transfer group.Median LOS was longer for patients requiring transfer (7 vs 5 days, P < 0.0001). One-third (34%) of the transfer patients had magnetic resonance cholangiopancreatography compared to only 7% that did not require transfer (P < 0.0001). Among the 123 patients who underwent ERCP before cholecystectomy, 53% required (66/123) transfer and 47% (57/123) did not. Transfer group patients had longer median hospital LOS (P < 0.0001), more days between admission and ERCP (P < 0.0001), and more days between ERCP and surgery (P = 0.0004). CONCLUSIONS: Overall median LOS was significantly shorter for patients who underwent ERCP at the admitting facility. Patients who underwent ERCP before cholecystectomy at hospitals without available ERCP proceduralists incurred longer LOS. There is a need for more pediatric proceduralists appropriately trained to perform ERCP in children.

Why wait: early enteral feeding after pediatric gastrostomy tube placement.

PURPOSE: Early initiation of feedings after gastrostomy tube (GT) placement may reduce associated hospital costs, but many surgeons fear complications could result from earlier feeds. We hypothesized that, irrespective of placement method, starting feedings within the first 6h following GT placement would not result in a greater number of post-operative complications. METHODS: An IRB-approved retrospective review of all GTs placed between January 2012 and December 2014 at three academic institutions was undertaken. Data was stratified by placement method and whether the patient was initiated on feeds at less than 6h or after. Baseline demographics, operative variables, post-operative management and complications were analyzed. Descriptive statistics were used and P-values <0.05 were considered significant. RESULTS: One thousand and forty-eight patients met inclusion criteria. GTs were inserted endoscopically (48.9%), laparoscopically (44.9%), or via an open approach (6.2%). Demographics were similar in early and late fed groups. When controlling for method of placement, those patients who were fed within the first 6h after gastrostomy placement had shorter lengths of stay compared to those fed greater than 6h after placement (P<0.05). Total post-operative outcomes were equivalent between feeding groups for all methods of placement (laparoscopic (P=0.87), PEG (P=0.94), open (P=0.81)). CONCLUSIONS: Early initiation of feedings following GT placement was not associated with an increase in complications. Feeds initiated earlier may shorten hospital stays and decrease overall hospital costs. TYPE OF STUDY: Multi-institutional retrospective. LEVEL OF EVIDENCE: III.

A comparison between non-powder gun and powder-gun injuries in a young pediatric population.

INTRODUCTION: Non-powder guns (NPG) are viewed as toys for children by the general public. Literature on firearm injuries in the pediatric population is increasing, however there are still large gaps in the published literature regarding NPG. We intended to identify and compare the epidemiology, circumstances of injury and outcomes of children with NPG versus powder-gun injuries (GSW). PATIENTS AND METHODS: We performed a 6-year retrospective analysis of children 0-14 years old treated for NPG and GSW injuries at our level one pediatric trauma center. Mann-Whitney U test and Pearson's X2 were used to compare continuous and categorical variables, respectively. RESULTS: There were 43 NPG and 112 GSWs. Patients were predominantly male (36 children; 84%) NPG vs. 92 children; 82% GSW) with a median age in both groups of 11 years. Analysis of residential zip codes showed that 74% (32 children) NPG injuries and 85% (95 children) GSW lived in regions with higher poverty than the national level. Children with NPG injuries were more likely to be Caucasian (24 children; 56%) and to have suffered an unintentional injury (36 children; 84%), while children with GSW were African-American (80 children; 71%; p=0.0002) and victims of assault (50 children; 45%; p<0.0001). When compared with NPG, children with GSW had more severe injuries, longer hospital stays, and higher overall mortality. There were no significant differences in rate of emergent OR intervention and ED mortality between the two groups. CONCLUSION: Our results highlight two important findings. First, NPG injuries were accidental and thus preventable with improved legislation and public education. Second, health disparities related to gun violence among African-Americans are prevalent even in early childhood and prevention efforts should include this younger population.
