RESUMEN
INTRODUCTION: Firearm injuries (FIs) are the leading cause of preventable morbidity and mortality in pediatric patients. In this study, we aim to define evolving trends and avenues for prevention. METHODS: Following institutional review board approval, medical records of patients presenting to our two State-Designated Level 1 Pediatric Trauma Centers for treatment of FIs from 2010 to 2019 were retrospectively reviewed. Data was analyzed with Chi-Squared and Student's t-test; P-value <0.05 was significant. RESULTS: 1037 FI encounters from 1005 unique patients aged 0-21 y were included. 70.4% (n = 730) were determined to be assaults, 26.1% (n = 271) unintentional, and 1.7% (n = 18) self-inflicted injuries. Overall mortality was 4.5% (n = 45). FI victims were most commonly African American (n = 836, 80.6%), male (n = 869, 83.8%), aged 13-17 (n = 753, 72.6%), and from single-parent families (n = 647, 62.4%). The incidence of FIs increased significantly over the last 5 y of the study (2010-2014, 6.8 FIs/month), compared to 2015-2019 (averaging 10.6 FIs/month, P < 0.0001). Concurrently, FI related fatality increased from an average of 2.6 deaths/year (2010-2014) to 6.4 deaths/year (2015-2019, P = 0.064). Results were subanalyzed for pediatric patients aged 0-14 y. For the entire cohort, 12.1% (n = 116) recidivists were identified. Geographic patterns of injury were identified, with 75% of all FIs clustered in a single urban region. CONCLUSIONS: Incidence of pediatric FIs is increasing in recent years, with high mortality rates. Violence and recidivism are geographically concentrated, offering an opportunity for targeted interventions.
RESUMEN
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.

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.

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.

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.

Retinoic acid receptor beta (RARB) variants are heavily linked to pathologies of neural crest cell migration. The purpose of this report is to present a 23-month-old male with the previously described R387C RARB gain-of-function variant whose gastrointestinal issues and long-term constipation lead to the discovery of colonic hypoganglionosis. This case further delineates the pattern of malformation associated with RARB variants. The findings are also consistent with the known etiology of aganglionic colon due to failed neural crest cell migration.

BACKGROUND: Short bowel syndrome (SBS) results from extensive bowel resection. Patients with SBS require total parenteral nutrition (TPN) for survival. Understanding mechanisms contributing to TPN-associated liver injury and gut atrophy are critical in developing SBS therapies. Existing SBS models using tethered animals have significant limitations and are unlike ambulatory human SBS patients. We hypothesized that we could induce SBS in piglets and develop an ambulatory TPN-SBS model. MATERIAL AND METHODS: Eighteen neonatal pigs received duodenal and jugular catheters. They were fitted with a jacket holding TPN and a miniaturized pump. Six piglets had 90% small bowel resection and catheter placement (SBS group). Non-SBS piglets were randomized into enteral nutrition (EN) or TPN. RESULTS: Bowel resection was successfully accomplished in SBS animals. Weight gain was similar in all groups. SBS animals had increased serum bilirubin compared to EN. Mean conjugated bilirubin ± SD was 0.045 ± 0.01 for EN, (P = 0.03 EN versus TPN and P = 0.03 SBS versus EN) and 1.09 ± 1.25 for TPN, (P = 0.62 TPN versus SBS). Gut density was reduced in the TPN group compared to EN and SBS groups. Mean gut density ± SD was 0.11 ± 0.04 for TPN (P = 0.0004 TPN versus SBS and P = 0.00007 TPN versus EN) and not statistically different for EN versus SBS (P = 0.32). CONCLUSIONS: We created a novel, ambulatory TPN-SBS model using piglets, mimicking long-term TPN delivery in human SBS patients. Our model demonstrated TPN-related conjugated hyperbilirubinemia and compensatory gut hypertrophy, as noted in humans with SBS. This model holds great potential for future research.

BACKGROUND: Radiation exposure is the reason for the decreased utilization of computed tomography (CT) in pediatric centers (PCs). We sought to compare the radiation dose exposure of CT imaging performed at outside hospitals (OH) versus PC in pediatric patients with acute appendicitis (AA). MATERIAL AND METHODS: A retrospective review of all patients managed at our PC for AA from January 2011 to March 2016 was performed. Patients who had CT imaging for AA at OH were compared to those who underwent CT for appendicitis at our PC. Radiation dosing was compared using the dose index (CTDI [mGY]) and dose length product (DLP [mGYcm]). Independent t-test samples were used to compare means for radiation dose. RESULTS: 379 patients met inclusion criteria. There were 59.4% (225) patients imaged at our PC and 40.6% (154) patients were transferred from an OH. When performed at OH, 6.5% of CTs were considered inadequate as they were done without intravenous contrast compared to 1.3% in our PC. Mean CTDI was 6.9 at our PC and 11.8 at OH (P < 0.0001). Mean DLP at PC was 296.2 versus 456.8 at OH (P < 0.0001). An excess radiation dose of 4.9 mGY and 160.5 mGYcm was noted when CT scan was performed at OH versus PC. CONCLUSIONS: Using DLP as a gauge of radiation exposure, CT imaging performed at OH has a 44% higher radiation rate relative to the exposure at PC. In cases of suspected AA at a facility without pediatric surgeons, early transfer to PC prior to imaging is advocated.

BACKGROUND: Little data exist regarding the recurrence of pancreatitis in pediatric patients with gallstone pancreatitis awaiting cholecystectomy. This study evaluates the recurrence rate of pancreatitis after acute gallstone pancreatitis based on the timing of cholecystectomy in pediatric patients. MATERIALS AND METHODS: A retrospective chart review of all patients admitted with gallstone pancreatitis from 2007 to 2015 was performed. Children were divided into the following five groups. Group 1 had surgery during the index admission. Group 2 had surgery within 2 wk of discharge. Group 3 had surgery between 2 and 6 wk postdischarge. Group 4 had surgery 6 wk after discharge, and group 5 patients had no surgery. The recurrence rates of pancreatitis were calculated for all groups. RESULTS: Forty-eight patients with gallstone pancreatitis were identified in this study. The 19 patients in group 1 had no recurrence of their pancreatitis. Of the remaining 29 patients, nine (31%) had recurrence of pancreatitis or required readmission for abdominal pain prior to their cholecystectomy. In group 2, two of the eight patients (25%) had recurrent pancreatitis. In group 3, three of eight patients (37.5%) developed recurrent pancreatitis. In group 4, three of five patients (60%), and in group 5, one of eight. No children in group 5 had demonstrable gallstones at presentation, only sludge in their gallbladder. CONCLUSIONS: Cholecystectomy during the index admission is associated with no recurrence or readmission for pancreatitis. Therefore, we recommend that cholecystectomy be performed after resolution of an episode of gallstone pancreatitis during index admission.

PURPOSE: The standard practice in pediatric patients diagnosed with intussusception has been reduction via enema and admission for a period of nil per os and observation. Little data exists to support this practice. The objective of this study was to examine whether post-reduction admission to hospital is required. METHODS: A retrospective chart review was performed on all patients aged 0-18 years old with intussusception over a span of 20 years. Study included children treated for intussusception on first encounter with enema and subsequently admitted for observation. Study excluded those readmitted for recurrence after 48 h, patients whose intussusception did not reduce on first try, those lost to follow-up, and those who went to the operating room. Early recurrence was defined as recurrence within 48 h post-reduction. RESULTS: Out of 171 patients admitted, only one experienced an early recurrence (0.6 %). Median length of stay for all patients was 2 days. Average cost incurred per day for intussusception admission was $404. CONCLUSION: Intussusception in a child that is successfully reduced via enema has a low recurrence rate and is usually followed by prompt resolution of symptoms. An abbreviated period of observation in the emergency department post-reduction may result in healthcare savings.

BACKGROUND: Small, single-institution studies have suggested risk factors for bowel ischemia/necrosis (I/N) in patients with computed tomography (CT) findings of pneumatosis (PN) and portal venous gas (PVG). Here, analysis has been expanded in a large, multicenter study. MATERIALS & METHODS: Logistic regression models and receiver operating characteristic curves were used to construct a scoring system for I/N in cases of PN/PVG. RESULTS: Of 265 patients with PN/PVG identified, 209 had adequate data. In unadjusted analyses the following variables were significantly associated with I/N: age, peritoneal signs, ascites, the presence of both PVG and PN, blood urea nitrogen (BUN), CO2, albumin, and a history of hypertension, myocardial infarction, or stroke. In contrast, the CT findings of mesenteric stranding, bowel-wall thickening, and type of PN were not associated with I/N. In adjusted analyses, three variables were significantly associated with I/N: age ≥60 y (odds ratio = 2.51, 95% confidence interval: 1.26-4.97), peritoneal signs (10.58, 4.23-26.4), and BUN >25 mg/dL (3.08, 1.54-6.17), whereas presence of both PN and PVG (versus only one) was associated with an increase (but not statistically significant increase) in odds (2.01, 0.94-4.36). Although several ad hoc models were used to maximize diagnostic ability, with maximal odds ratio = 174, the areas of receiver operating characteristic curves were all below 0.80, revealing suboptimal accuracy to diagnose I/N. CONCLUSIONS: Older age, peritoneal signs, and high BUN are associated with I/N, suggesting an ability to predict which patients need operation. CT findings traditionally suggestive of ischemic PN/PVG, however, do not diagnose I/N accurately enough to reliably identify patients needing operation.

We describe a case of congenital giant megaureter in a 16-year-old female. She presented with a 5-day history of abdominal distention, right flank pain and tenderness. Right pyelonephritis was suspected. Computerized tomography showed a large cystic abdominal mass with no appreciably functioning left kidney causing secondary compression of the contralateral right ureter. A left upper nephroureterectomy was performed, draining over 3.5 L of fluid. Our experience suggests that congenital giant megaureter should be considered in the differential for pediatric patients presenting with a cystic abdominal mass.

Purpose: Single-incision laparoscopic appendectomy (SILA) for the treatment of appendicitis has been documented. Typically, SILA requires the use of specialized ports, instruments, and materials. The SILA technique at our institution utilizes the same instrumentation as the conventional laparoscopic approach (CLA), thus obviating the need for these specialized products. This study aims to further demonstrate the noninferiority of our SILA technique for the treatment of uncomplicated appendicitis. Materials and Methods: This is a single-institution retrospective review of patients who underwent SILA from 2011 to 2020 to treat uncomplicated appendicitis. Outcomes including demographics, operative time, length of stay (LOS), and common postsurgical complications were evaluated. These SILA cases were matched with up to 3 CLA controls based on age, gender, and weight utilizing the Greedy match method. Patients with an operative diagnosis of perforated appendicitis were excluded. Results: A total of 137 patients underwent SILA at a single institution. A total of 128 patients were in the final cohort after excluding perforated appendicitis. Mean age was 11.9 years. Case-control matching was conducted with 349 controls included. Between cases and controls, SILA had shorter operative time (27.2 minutes versus 43.7 minutes, P < .001) with no difference in mean LOS (42.4 hours versus 42.4 hours, P = .88). There was no difference in complication rate (5.4% versus 8.5%, P = .06). There was no difference in readmission rate (0.8% versus 3.4%, P = .108). Conclusion: These data suggest that for appropriately selected patients, our SILA technique is noninferior to CLA with shortened operative time.

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.
RESUMEN
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.

BACKGROUND: The regulation of intestinal barrier permeability is important in the maintenance of normal intestinal physiology. Sphingosine-1-phosphate (S1P) has been shown to play a pivotal role in enhancing barrier function in several non-intestinal tissues. The current study determined whether S1P regulated function of the intestinal epithelial barrier by altering expression of E-cadherin, an important protein in adherens junctions. METHODS: Studies were performed upon cultured differentiated IECs (IEC-Cdx2L1 line) using standard techniques. RESULTS: S1P treatment significantly increased levels of E-cadherin protein and mRNA in intestinal epithelial cells (IECs) and also led to E-cadherin localizing strongly to the cell-cell border. S1P also improved the barrier function as indicated by a decrease in 14C-mannitol paracellular permeability and an increase in transepithelial electrical resistance (TEER) in vitro. CONCLUSIONS: These results indicate that S1P increases levels of E-cadherin, both in cellular amounts and at the cell-cell junctions, and leads to improved barrier integrity in cultured intestinal epithelial cells.

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.

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 nâ¯=â¯110 vs. laparotomy nâ¯=â¯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 48â¯h after intervention. Patients who were treated primarily with a drain were more premature (24.9 vs. 27.2â¯weeks, pâ¯<â¯0.001) and had lower median birth weight (710â¯g vs. 896â¯g, pâ¯<â¯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, pâ¯=â¯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.

OBJECTIVE: The regulation of apoptosis of intestinal mucosal cells is important in maintenance of normal intestinal physiology. SUMMARY: Sphingosine-1-phosphate (S1P) has been shown to play a critical role in cellular protection to otherwise lethal stimuli in several nonintestinal tissues. METHODS: The current study determines whether S1P protected normal intestinal epithelial cells (IECs) from apoptosis and whether Akt activation was the central pathway for this effect. RESULTS: S1P demonstrated significantly reduced levels of apoptosis induced by tumor necrosis factor-alpha (TNF-alpha)/cycloheximide (CHX). S1P induced increased levels of phosphorylated Akt and increased Akt activity, but did not affect total amounts of Akt. This activation of Akt was associated with decreased levels of both caspase-3 protein levels and of caspase-3 activity. Inactivation of Akt by treatment with the PI3K chemical inhibitor LY294002 or by overexpression of the dominant negative mutant of Akt (DNMAkt) prevented the protective effect of S1P on apoptosis. Additionally, silencing of the S1P-1 receptor by specific siRNA demonstrated a lesser decrease in apoptosis to S1P exposure. CONCLUSION: These results indicate that S1P protects intestinal epithelial cells from apoptosis via an Akt-dependent pathway.

BACKGROUND: No consensus exists regarding duration of antibiotic therapy for complicated appendicitis treated with interval appendectomy. We hypothesized that more than two weeks of antibiotic therapy does not decrease complication rates in asymptomatic patients. PATIENTS AND METHODS: A retrospective review of all patients with complicated appendicitis treated with interval appendectomy from 2010-2015 was performed. We divided the patients in two groups (group 1, ≤2 weeks of antibiotics; group 2: >2 weeks of antibiotics). Demographics, antibiotic agents, and complications were collected. Pearson χ analysis and Student t-test analysis was performed with significance of p < 0.05. RESULTS: Total of 158 patients met inclusion criteria (group 1 [47.4%] vs. group 2 [52.5%]). Mean length of stay was 7.5 days. Abscess on admission was 26% (n = 41). The groups were demographically similar. Total complication rate was 39.2% (abscess development, n = 19; re-admissions, n = 16; interval appendectomy <28 days, n = 13; unplanned emergency department visits, n = 7; fistula, n = 4, wound infection/dehiscence, n = 3; and conversion to open surgery, n = 4). All fistulas and conversions occurred in the less than two-week group. Mean course of antibiotics was 4.1 weeks. There was no significant difference in the complication rates based on duration or type of antibiotics (p = 1.0). CONCLUSION: Treatment with more than two weeks of antibiotic therapy for complicated appendicitis does not confer any clinical benefit prior to interval appendectomy. Complications were not reduced by a prolonged course of antibiotic therapy.
