RESUMEN
OBJECTIVE: The purpose of this study is to investigate noninferiority of postoperative oral administration of antibiotics in complicated appendicitis. BACKGROUND: Recent investigations have used exclusively intravenous administration of antibiotics when comparing outcomes of postoperative antibacterial therapy in complicated appendicitis. We hypothesized that oral antibacterial treatment results in noninferior outcomes in terms of postoperative infectious complications as intravenous treatment. METHODS: In this pilot, open-label, prospective randomized trial, all consecutive adult patients with complicated appendicitis, including gangrenous appendicitis, perforated appendicitis, and appendicitis with periappendicular abscess between November 2020 and January 2023, were randomly allocated to 24-hour intravenous administration of antibiotics versus 24-hour oral administration of antibiotics after appendectomy. Primary outcomes included 30-day postoperative complications per Comprehensive Complication Index. The secondary outcome was hospital length of stay. Follow-up analysis at 30 days was conducted per intention to treat and per protocol. The study was registered at ClinicalTrials.gov (NCT04947748). RESULTS: A total of 104 patients were enrolled, with 51 and 53 cases allocated to the 24-hour intravenous and the 24-hour oral treatment group, respectively. Demographic profile and disease severity score for acute appendicitis were similar between the study groups. There were no significant differences between the study groups in terms of 30-day postoperative complications. Median Comprehensive Complication Index did not differ between the study groups. Hospital length of stay was similar in both groups. CONCLUSIONS: In the current pilot randomized controlled trial, the 24-hour oral antibiotic administration resulted in noninferior outcomes when compared with the 24-hour intravenous administration of antibiotics after laparoscopic appendectomy in complicated appendicitis.

OBJECTIVE: To compare costs for 2 days versus 5 days of postoperative antibiotics within the antibiotics after an aPPendectomy In Complex appendicitis trial.Background:Recent studies suggest that restrictive antibiotic use leads to a significant reduction in hospital stays without compromising patient safety. Its potential effect on societal costs remains underexplored. METHODS: This was a pragmatic, open-label, multicenter clinical trial powered for noninferiority. Patients with complex appendicitis (age ≥ 8 years) were randomly allocated to 2 days or 5 days of intravenous antibiotics after appendectomy. Patient inclusion lasted from June 2017 to June 2021 in 15 Dutch hospitals. The final follow-up was on September 1, 2021. The primary trial endpoint was a composite endpoint of infectious complications and mortality within 90 days. In the present study, the main outcome measures were overall societal costs (comprising direct health care costs and costs related to productivity loss) and cost-effectiveness. Direct health care costs were recorded based on data in the electronic patient files, complemented by a telephone follow-up at 90 days. In addition, data on loss of productivity were acquired through the validated Productivity Cost Questionnaire at 4 weeks after surgery. Cost estimates were based on prices for the year 2019. RESULTS: In total, 1005 patients were evaluated in the "intention-to-treat" analysis: 502 patients were allocated to the 2-day group and 503 to the 5-day group. The mean difference in overall societal costs was - 625 (95% CI: - 958 to - 278) to the advantage of the 2-day group. This difference was largely explained by reduced hospital stay. Productivity losses were similar between the study groups. Restricting postoperative antibiotics to 2 days was cost-effective, with estimated cost savings of 31,117 per additional infectious complication. CONCLUSIONS: Two days of postoperative antibiotics for complex appendicitis results in a statistically significant and relevant cost reduction, as compared with 5 days. Findings apply to laparoscopic appendectomy in a well-resourced health care setting.

OBJECTIVE: To evaluate the safety, efficacy, and cost-effectiveness of outpatient appendectomy in patients with uncomplicated acute appendicitis. BACKGROUND: Given that acute appendicitis is the most common cause of acute abdomen, the introduction of outpatient appendectomy protocols could significantly improve the effectiveness and sustainability of health care systems. METHODS: A total of 300 patients were enrolled from October 2018 to June 2021 in the PENDI-CSI randomized clinical trial: 149 were assigned to the outpatient surgery (OPS) group and 151 to the inpatient surgery (IPS) group, followed by 1 month postoperatively. All patients were aged older than 14 years and had uncomplicated acute appendicitis. Exclusion criteria were pregnancy, neoplasms, inflammatory bowel disease, and high anesthetic risk (ASA IV). The OPS group was discharged from the postanesthesia care unit while the IPS group was admitted. RESULTS: In total, 128 patients in the OPS group (85.9%) were discharged without admission. Predictors whether patients in the OPS group had to be admitted were aged over 31 years [relative risk (RR): 2.42 (1.04-5.65)], hypertension [RR: 6.21 (3.22-11.97)], anesthetic risk II-III [RR: 2.63 (1.17-5.94)], previous abdominal surgery [RR: 3.34 (1.55-7.20)], postoperative pain with visual analog scale >6 [RR: 4.28 (2.67-6.86)], and postoperative fear [RR: 2.2 (1.04-4.67)]. There were no differences in terms of complications, readmissions, and reinterventions, and the perceived quality was similar in both groups. The outpatient modality produced savings of 1 034.97 per patient ( P < 0.001). CONCLUSIONS: Outpatient appendectomy is safe and effective for uncomplicated acute appendicitis. Patient-perceived quality is similar to that of IPS, although it successfully reduces hospital costs compared with inpatient appendectomy.

OBJECTIVE: To assess whether delaying appendectomy until the following morning is non-inferior to immediate surgery in those with acute appendicitis presenting at night. BACKGROUND: Despite a lack of supporting evidence, those with acute appendicitis who present at night frequently have surgery delayed until the after morning. METHODS: The delay trial is a noninferiority randomized controlled trial conducted between 2018 and 22 at 2 tertiary care hospitals in Canada. Adults with imaging confirmed acute appendicitis who presented at night (8:00 pm -4:00 am ). Delaying surgery until after 6:00 am was compared with immediate surgery. The primary outcome was 30-day postoperative complications. An a prior noninferiority margin of 15% was deemed clinically relevant. RESULTS: One hundred twenty-seven of the planned 140 patients were enrolled in the Delayed Versus Early Laparoscopic Appendectomy (DELAY) trial (59 in the delayed group and 68 in the immediate group). The two groups were similar at baseline. The mean time between the decision to operate and surgery was longer in the delayed group (11.0 vs 4.4 hours, P < 0.0001). The primary outcome occurred in 6/59 (10.2%) of those in the delayed group versus 15/67 (22.4%) of those in the immediate group ( P = 0.07). The difference between groups met the a priori noninferiority criteria of +15% (risk difference -12.2%, 95% CI: -24.4% to +0.4%, test of noninferiority P < 0.0001). CONCLUSIONS: The DELAY study is the first trial to assess delaying appendectomy in those with acute appendicitis. We demonstrate the noninferiority of delaying surgery until the after morning.

BACKGROUND: Appendicectomy remains the standard treatment for appendicitis. No international consensus exists on the surgical urgency for acute uncomplicated appendicitis, and recommendations vary from surgery without delay to surgery within 24 h. Longer in-hospital delay has been thought to increase the risk of perforation and further morbidity. Therefore, we aimed to compare the rate of appendiceal perforation in patients undergoing appendicectomy scheduled to two different urgencies (<8 h vs <24 h). METHODS: In this pragmatic, open-label, multicentre, non-inferiority, parallel, randomised controlled trial in two hospitals in Finland and one in Norway, patients (aged ≥18 years) with presumed uncomplicated acute appendicitis were randomly assigned (1:1) to an appendicectomy scheduled within 8 h or within 24 h to determine whether longer in-hospital delay (time between randomisation and surgical incision) is not inferior to shorter delay. Patients were excluded in cases of pregnancy, suspicion of perforated appendicitis (C-reactive protein level of ≥100 mg/L, fever >38·5°C, signs of complicated appendicitis on imaging studies, or clinical generalised peritonitis), or other reasons requiring prompt surgery. The recruiters were on-duty surgeons who decided to proceed with the appendicectomy. The randomisation sequence was generated using block randomisation with randomly varying block sizes and stratified by hospital districts; neither physicians nor patients were masked to group assignment. The primary outcome was perforated appendicitis diagnosed during surgery analysed in all patients who received an appendicectomy by intention to treat. The absolute difference in rates of perforated appendicitis was compared between the groups. Complications and other safety outcomes were analysed in all patients who received an appendicectomy. A margin of 5 percentage points was used to establish non-inferiority. This trial was registered at ClinicalTrials.gov (NCT04378868) and is closed to accrual. FINDINGS: Between May 18, 2020, and Dec 31, 2022, 2095 patients were assessed for eligibility, of whom 1822 were randomly assigned to appendicectomy scheduled within 8 h (n=914) or 24 h (n=908). After randomisation, 19 (1%) of 1822 patients were excluded due to protocol violation. 1803 patients were included in the intention-to-treat analyses, 985 (55%) of whom were male and 818 (45%) female. Appendiceal perforation rate was similar between groups (77 [8%] of 907 patients assigned to the <8 h group and 81 [9%] of 896 patients assigned to the <24 h group; absolute risk difference 0·6% [95% CI -2·1 to 3·2], p=0·68; risk ratio 1·065, 95% CI 0·790 to 1·435). No significant difference was found between the complication rates within 30 days (66 [7%] of 907 patients in the <8 h group vs 56 [6%] of 896 patients in the <24 h group; difference -1·0% [-3·3 to 1·3]; p=0·39), and no deaths occurred during this follow-up period. INTERPRETATION: In patients with presumed uncomplicated acute appendicitis, scheduling appendicectomy within 24 h does not increase the risk of appendiceal perforation compared with scheduling appendicectomy within 8 h. The results can be used to allocate operating room resources, for example postponing night-time appendicectomy to daytime.

BACKGROUND: The appropriate duration of postoperative antibiotics for complex appendicitis is unclear. The increasing global threat of antimicrobial resistance warrants restrictive antibiotic use, which could also reduce side-effects, length of hospital stay, and costs. METHODS: In this pragmatic, open-label, non-inferiority trial in 15 hospitals in the Netherlands, patients with complex appendicitis (aged ≥8 years) were randomly assigned (1:1) to receive 2 days or 5 days of intravenous antibiotics after appendicectomy. Randomisation was stratified by centre, and treating physicians and patients were not masked to treatment allocation. The primary endpoint was a composite endpoint of infectious complications and mortality within 90 days. The main outcome was the absolute risk difference (95% CI) in the primary endpoint, adjusted for age and severity of appendicitis, with a non-inferiority margin of 7·5%. Outcome assessment was based on electronic patient records and a telephone consultation 90 days after appendicectomy. Efficacy was analysed in the intention-to-treat and per-protocol populations. Safety outcomes were analysed in the intention-to-treat population. This trial was registered with the Netherlands Trial Register, NL5946. FINDINGS: Between April 12, 2017, and June 3, 2021, 13 267 patients were screened and 1066 were randomly assigned, 533 to each group. 31 were excluded from intention-to-treat analysis of the 2-day group and 30 from the 5-day group owing to errors in recruitment or consent. Appendicectomy was done laparoscopically in 955 (95%) of 1005 patients. The telephone follow-up was completed in 664 (66%) of 1005 patients. The primary endpoint occurred in 51 (10%) of 502 patients analysed in the 2-day group and 41 (8%) of 503 patients analysed in the 5-day group (adjusted absolute risk difference 2·0%, 95% CI -1·6 to 5·6). Rates of complications and re-interventions were similar between trial groups. Fewer patients had adverse effects of antibiotics in the 2-day group (45 [9%] of 502 patients) than in the 5-day group (112 [22%] of 503 patients; odds ratio [OR] 0·344, 95% CI 0·237 to 0·498). Re-admission to hospital was more frequent in the 2-day group (58 [12%] of 502 patients) than in the 5-day group (29 [6%] of 503 patients; OR 2·135, 1·342 to 3·396). There were no treatment-related deaths. INTERPRETATION: 2 days of postoperative intravenous antibiotics for complex appendicitis is non-inferior to 5 days in terms of infectious complications and mortality within 90 days, based on a non-inferiority margin of 7·5%. These findings apply to laparoscopic appendicectomy conducted in a well resourced health-care setting. Adopting this strategy will reduce adverse effects of antibiotics and length of hospital stay.

BACKGROUND AND AIMS: The aim of this study was to investigate the safety and efficacy of appendicoscopy using a single-operator cholangioscope (SOC) for the management of acute obstructive appendicitis. METHODS: This study describes 110 cases of acute obstructive appendicitis managed with the use of appendicoscopy between January 2021 and June 2023. The success rate (technical + clinical), procedure time, time to abdominal pain relief according to a visual analog scale score, postoperative length of hospital stay, and adverse event rates were recorded and analyzed. RESULTS: The technical success rate of appendicoscopy was 96.4%, and the clinical success rate was 91.8%. The mean ± standard deviation procedure time was 20.9 ± 10 minutes. The abdominal pain score at 6 hours after the procedure was ≤3 (visual analog scale method) in 99.1% of patients. The average length of postoperative hospital stay was 3.5 ± 1.5 days. No adverse events occurred. CONCLUSIONS: Appendicoscopy seems to be a feasible and effective alternative therapy for the accurate diagnosis and treatment of acute obstructive appendicitis.

BACKGROUND: Observational studies of anesthetic neurotoxicity may be biased because children requiring anesthesia commonly have medical conditions associated with neurobehavioral problems. This study takes advantage of a natural experiment associated with appendicitis to determine whether anesthesia and surgery in childhood were specifically associated with subsequent neurobehavioral outcomes. METHODS: This study identified 134,388 healthy children with appendectomy and examined the incidence of subsequent externalizing or behavioral disorders (conduct, impulse control, oppositional defiant, attention-deficit hyperactivity disorder) or internalizing or mood or anxiety disorders (depression, anxiety, or bipolar disorder) when compared to 671,940 matched healthy controls as identified in Medicaid data between 2001 and 2018. For comparison, this study also examined 154,887 otherwise healthy children admitted to the hospital for pneumonia, cellulitis, and gastroenteritis, of which only 8% received anesthesia, and compared them to 774,435 matched healthy controls. In addition, this study examined the difference-in-differences between matched appendectomy patients and their controls and matched medical admission patients and their controls. RESULTS: Compared to controls, children with appendectomy were more likely to have subsequent behavioral disorders (hazard ratio, 1.04; 95% CI, 1.01 to 1.06; P = 0.0010) and mood or anxiety disorders (hazard ratio, 1.15; 95% CI, 1.13 to 1.17; P < 0.0001). Relative to controls, children with medical admissions were also more likely to have subsequent behavioral (hazard ratio, 1.20; 95% CI, 1.18 to 1.22; P < 0.0001) and mood or anxiety (hazard ratio, 1.25; 95% CI, 1.23 to 1.27; P < 0.0001) disorders. Comparing the difference between matched appendectomy patients and their matched controls to the difference between matched medical patients and their matched controls, medical patients had more subsequent neurobehavioral problems than appendectomy patients. CONCLUSIONS: Although there is an association between neurobehavioral diagnoses and appendectomy, this association is not specific to anesthesia exposure and is stronger in medical admissions. Medical admissions, generally without anesthesia exposure, displayed significantly higher rates of these disorders than appendectomy-exposed patients.

INTRODUCTION: Immediate complications of appendicitis are common, but the prevalence of long-term complications is uncertain. METHODS: We studied all publicly-insured children in the US with uncomplicated or complicated appendicitis in 2018-2019 using administrative claims. The main outcome was late hospital care defined as hospitalization or abdominal procedure within 180 d of an appendicitis discharge, excluding interval appendectomies. Time to late hospital care was evaluated using Cox regression. We evaluated health-care expenditures arising from appendicitis episodes. RESULTS: Among 95,942 children with appendicitis, 5727 (6.0%) had late hospital care, with 5062 requiring rehospitalization and 2012 (2.1%) surgery. The median time to late hospital care was 10 d (interquartile range 4-33). Age under 5 y (compared with >14 y, hazard ratio [HR] 1.88, 95% confidence interval [CI] 1.70-2.08), complex chronic conditions (HR 2.35, 95% CI 2.13-2.59), and complicated appendicitis (HR 2.81, 95% CI 2.67, 2.96) were each associated with time to late hospital care. Expenditures over 180 d were a median $6553 and $19,589 respectively in those requiring no late hospital care versus those requiring it (P < 0.001). CONCLUSIONS: Late hospital care is uncommon in pediatric appendicitis but is costly. Prevention efforts should be targeted to the youngest, most complex children, and those with complicated appendicitis at presentation.

INTRODUCTION: Markers of postoperative recovery in pediatric patients are difficult for parents to evaluate after hospital discharge, who use subjective proxies to assess recovery and the onset of complications. Consumer-grade wearable devices (e.g., Fitbit) generate objective recovery data in near real time and thus may provide an opportunity to remotely monitor postoperative patients and identify complications beyond the initial hospitalization. The aim of this study was to use daily step counts from a Fitbit to compare recovery in patients with complications to those without complications after undergoing appendectomy for complicated appendicitis. METHODS: Children ages 3-17 years old undergoing laparoscopic appendectomy for complicated appendicitis were recruited. Patients wore a Fitbit device for 21 d after operation. After collection, patient data were included in the analysis if minimum wear-time criteria were achieved. Postoperative complications were identified through chart review, and step count trajectories for patients recovering with and without complications were compared. Additionally, to account for the patients experiencing a complication on different postoperative days, median daily step count for pre- and post-complication were analyzed. RESULTS: Eighty-six patients with complicated appendicitis were enrolled in the study, and fourteen children developed a postoperative complication. Three patients were excluded because they did not meet the minimum wear time requirements. Complications were divided into abscesses (n = 7, 64%), surgical site infections (n = 2, 18%), and other, which included small bowel obstruction and Clostridioides difficile infection (n = 2, 18%). Patients presented with a complication on mean postoperative day 8, while deviation from the normative recovery trajectory was evident 4 d prior. When compared to children with normative recovery, the patients with surgical complications experienced a slower increase in step count postoperatively, but the recovery trajectory was specific to each complication type. When corrected for day of presentation with complication, step count remained low prior to the discovery of the complication and increased after treatment resembling the normative recovery trajectory. CONCLUSIONS: This study profiled variations from the normative recovery trajectory in patients with complication after appendectomy for complicated appendicitis, with distinct trajectory patterns by complication type. Our findings have potentially profound clinical implications for monitoring pediatric patients postoperatively, particularly in the outpatient setting, thus providing objective data for potentially earlier identification of complications after hospital discharge.

INTRODUCTION: Counseling patients and parents about the postoperative recovery expectations for physical activity after pediatric appendectomy varies significantly and is not specific to patients' demographic characteristics. Consumer wearable devices (CWD) can be used to objectively assess patients' normative postoperative recovery of physical activity. This study aimed to develop demographic-specific normative physical activity recovery trajectories using CWD in pediatric patients undergoing appendectomy. METHODS: Children ages 3-18 y old undergoing laparoscopic appendectomy for acute appendicitis were recruited. Patients wore a Fitbit device for 21 d postoperatively and daily step counts were measured. Patients with postoperative complications were excluded. Segmented regression models were fitted and time-to-plateau was estimated for patients with simple and complicated appendicitis separately for each age group, sex, race/ethnicity, and body mass index category. RESULTS: Among 147 eligible patients; 76 (51.7%) were female, 86 (58.5%) were in the younger group, and 79 (53.7%) had complicated appendicitis. Patients 3-11 y old demonstrated a faster trajectory to a physical activity plateau compared to those 12-18 in both simple (postoperative day [POD] 9 versus POD 17) and complicated appendicitis (POD 17 versus POD 21). Males and females had a similar postoperative recovery trajectory in simple and complicated appendicitis. There was no clear pattern differentiating trajectories based on race/ethnicity. Overweight/obese patients demonstrated a slower recovery trajectory in simple appendicitis. CONCLUSIONS: This study demonstrates that factors other than the disease itself, such as age, may affect recovery, suggesting the need for more tailored discharge instructions. CWDs can improve our understanding of recovery and allow for better data-driven counseling perioperatively.

INTRODUCTION: Postoperative (postop) management of pediatric perforated appendicitis varies significantly, and postop intra-abdominal abscesses (IAA) remain a significant issue. Between 2019 and 2020, our standardized protocol included routine postop labs after an appendectomy for perforated appendicitis. However, given the lack of predictive utility of these routine labs, we discontinued this practice in 2021. We hypothesize that discontinuing routine postop labs will not be associated with an increase in complication rates after an appendectomy for pediatric perforated appendicitis. METHODS: A single-institution, retrospective review of all pediatric appendectomies for perforated appendicitis from January 2019 to December 2021 was conducted at University Hospitals Rainbow Babies and Children's Hospital in Cleveland, Ohio. Data were collected on rate of complications (IAA development, re-admissions, bowel obstructions, superficial surgical site infections, intensive care unit transfers, Clostridium difficile infections, allergic reactions, and transfusions), postop imaging, postop interventions, and length of stay. Statistical analysis was completed using Fisher's exact test and Mann-Whitney U-test. RESULTS: A total of 109 patients (2019-2020 n = 61, 2021 n = 48) were included in the study. All 61 patients from 2019 to 2020 had postop labs compared to only eight patients in 2021. There was no statistically significant difference between the two groups in overall complication rates, but there was a decrease in IAAs reported in 2021 (P = 0.03). There were no statistically significant differences in other complications, postop imaging usage, or postop interventions. The median length of stay was 4.5 d in 2021 compared to 6.0 d in 2019-2020 (P = 0.009). CONCLUSIONS: Discontinuing routine postop labs is not associated with an increase in overall complications rates. Further studies are needed to determine whether routine postop labs can be safely removed in pediatric patients with perforated appendicitis, which would reduce patient discomfort and care costs.

INTRODUCTION: Pediatric surgical care is becoming increasingly regionalized, often resulting in limited access. Interfacility transfers pose a significant financial and emotional burden to when they are potentially avoidable. Of transferred patients, we sought to identify clinical factors associated with avoidable transfers in pediatric patients with suspected appendicitis. METHODS: We performed a single-center retrospective study at an academic tertiary referral children's hospital in an urban setting. We included children who underwent interfacility transfer to our center with a transfer diagnosis of appendicitis from July 1, 2021 to June 30, 2023. Encounters were designated as either an appropriate transfer (underwent appendectomy) or an avoidable transfer (did not undergo appendectomy). Encounters treated nonoperatively for complicated appendicitis were excluded. Bivariate analysis was performed using Mann-Whitney test and chi-square tests. RESULTS: A total of 444 patients were included: 71.2% were classified as appropriate transfers and 28.8% as avoidable transfers. Patients with avoidable transfer were younger compared to those in the appropriate transfer cohort (median age 9 y, interquartile range: 7-13 versus 11 y, interquartile range: 8-14; P < 0.001). Avoidable transfers less frequently presented with the typical symptoms of fever, migratory abdominal pain, anorexia, and nausea/emesis (P = 0.005). Avoidable transfers also reported shorter symptom duration (P = 0.040) with lower median white blood cell count (P < 0.001), neutrophil percentage (P < 0.001), and C-reactive protein levels (P < 0.003). Avoidable transfers more frequently underwent repeat imaging upon arrival (42.9% versus 12.7%, P < 0.001). CONCLUSIONS: These findings highlight the importance of clinical history in children with suspected appendicitis. Younger patients without typical symptoms of appendicitis, those with a shorter duration of symptoms, and lower serum inflammatory markers may benefit from close observation without transfer.

INTRODUCTION: Nonoperative management (NOM) of uncomplicated appendicitis (UA) has been increasingly utilized in recent years. The aim of this study was to describe nationwide trends of sociodemographic characteristics, outcomes, and costs of patients undergoing medical versus surgical management for UA. METHODS: The 2018-2019 National (Nationwide) Inpatient Sample was queried for adults (age ≥18 y) with UA; diagnosis, as well as laparoscopic and open appendectomy, were defined by the International Classification of Diseases, 10th Revision, Clinical Modification codes. We examined several characteristics, including cost of care and length of hospital stay. RESULTS: Among the 167,125 patients with UA, 137,644 (82.4%) underwent operative management and 29,481 (17.6%) underwent NOM. In bivariate analysis, we found that patients who had NOM were older (53 versus 43 y, P < 0.001) and more likely to have Medicare (33.6% versus 16.1%, P < 0.001), with higher prevalence of comorbidities such as diabetes (7.8% versus 5.5%, P < 0.001). The majority of NOM patients were treated at urban teaching hospitals (74.5% versus 66.3%, P < 0.001). They had longer LOS's (5.4 versus 2.3 d, P < 0.001) with higher inpatient costs ($15,584 versus $11,559, P < 0.001) than those who had an appendectomy. Through logistic regression we found that older patients had up to 4.03-times greater odds of undergoing NOM (95% CI: 3.22-5.05, P < 0.001). CONCLUSIONS: NOM of UA is more commonly utilized in patients with comorbidities, older age, and those treated in teaching hospitals. This may, however, come at the price of longer length of stay and higher costs. Further guidelines need to be developed to clearly delineate which patients could benefit from NOM.

BACKGROUND: Appendicitis in pancreatic transplant recipients can be challenging to diagnose and manage. Incidental appendicectomy (IA) during pancreas transplantation obviates the risk of appendicitis but potentially at the cost of increased operating time or early post-operative complications. This study reviewed the value of IA at a single center. METHODS: This was a retrospective study of patients who underwent a pancreas transplant in our unit from January 1st, 2012 to December 31st, 2020, with end of follow-up on May 21st, 2023; recipients were grouped by whether or not an IA was performed during pancreas transplantation. Donor, recipient, operative, and graft outcomes were compared between the two groups. Post-transplant complications related to appendiceal pathology (or IA) were recorded and classified. RESULTS: Two hundred forty-three patients underwent a pancreas transplant; 227 (93%) patients had an appendix in situ at transplantation, and of these 53 (23%) underwent an IA and 174 (77%) did not. There were no statistically significant differences in operative time (p = .06) or hospital stay (p = .50) between the two groups. In the IA cohort, there were no Clavien-Dindo Grade III-V complications relating to the appendicectomy. In those that did not undergo an IA, two patients (1%) subsequently required appendicectomy due to appendicitis. Comparison of pancreatic graft survival showed no statistically significant difference between the groups (p = .44). CONCLUSIONS: This study suggests that IA is effective at reducing risks of post-transplant appendiceal complications without significantly prolonging inpatient stay or impairing graft survival. These data support the consideration of undertaking an IA for all patients undergoing a pancreas transplant.

Acute appendicitis (AA) in pediatric patients with acute leukemia mandates prompt treatment. Diagnosis presents challenges, relying on clinical and radiological assessments, often leading to treatment delays that may disrupt leukemia management. Our study on 14 such cases underscores the pivotal role of swift intervention. While conservative AA treatment may pose no risk to healthy children, our findings mandate the performance of laparoscopic appendectomy within 24 hours of diagnosis. This strategy yielded successful surgical outcomes while ensuring uninterrupted leukemia care. Our experience contributes important insights to the limited understanding of navigating this complex clinical scenario.

INTRODUCTION: Conservative treatment of acute appendicitis is gaining popularity, and identifying patients with a higher risk of recurrence is becoming increasingly important. Previous studies have suggested that older age, male sex, diabetes, appendicolith and abscess formation may be contributing factors, however, results from the adult population are inconsistent. AIM: This study aims to identify predictive factors for recurrent appendicitis after conservative treatment. METHODS: This retrospective study included patients with conservatively treated acute appendicitis at Skåne University Hospital, Sweden during 2012-2019. Information on patient demographics at index admission and follow-up data were retrieved from medical charts and radiologic images. Uni -and multivariable logistic regression analysis were performed using Stata Statistical Software. RESULTS: In total, 379 patients with conservatively treated acute appendicitis were identified, of which 78 (20.6%) had recurrence. All patients were followed-up for a minimum of 41 months after the first diagnosis of acute appendicitis unless appendectomy after successful conservative treatment or death occurred during follow-up. The median time to recurrence was 6.5 (1-17.8) months. After multivariable logistic regression analysis, external appendix diameter >10 mm [OR 2.4 (CI 1.37-4.21), p = .002] and intra-abdominal abscess [OR 2.05 (CI 1.18-3.56), p = .011] on computed tomography were significant independent risk factors for recurrent appendicitis. Appendicolith was not associated with an increased risk of recurrence. CONCLUSION: This study suggests abscess formation and appendix distension of >10 mm to be potential risk factors for recurrent acute appendicitis after initial successful conservative treatment.

PURPOSE: Our study investigates ethnic disparities in pediatric appendicitis, focusing on the impact of Hispanic ethnicity on presentation, complications, and postoperative outcomes. METHODS: We conducted a retrospective analysis of pediatric patients undergoing appendectomy for acute appendicitis from 2015 to 2020 using the National Surgical Quality Improvement Program-Pediatric database. We compared 30-day postoperative complications, postoperative length of stay, and postoperative interventions between Hispanic and non-Hispanic White patients. RESULTS: 65,976 patients were included, of which 23,462 (35.56%) were Hispanic and 42,514 (64.44%) non-Hispanic White. Hispanic children were more likely to present to the hospital with complicated appendicitis (31.75% vs. 25.15%, P < 0.0001) and sepsis (25.22% vs. 19.02%, P < 0.0001) compared to non-Hispanic White. Hispanics had higher rates of serious complications (4.06% vs. 3.55%, P = 0.001) but not overall complications (5.37% vs. 5.09%, P = 0.12). However, after multivariate analysis, Hispanic ethnicity was not associated with an increased rate of serious postoperative complications (OR 0.93, CI 0.85-1.01, P = 0.088); it was associated with less overall complications (OR 0.88, CI 0.81-0.96, P = 0.003) but a longer postoperative length of stay (OR 1.09, CI 1.04-1.14, P < 0.0001). CONCLUSION: Hispanic children are more likely to present with complicated appendicitis, contributing to increased postoperative complications. Notably, upon adjustment for the impact of complicated appendicitis, our findings suggest potentially favorable outcomes for Hispanic ethnicity. This emphasizes the need to understand delays in presentation to improve outcomes in the Hispanic population.

BACKGROUND: Appendicitis is one of the most common acute surgical conditions globally. However, the association between nighttime appendectomy and patients' morbidity and mortality is unclear. This study aims to compare outcomes following nighttime versus daytime appendectomy. METHODS: The PubMed, Embase, Cochrane Library, and Web of Science databases up to March 26, 2024 (updated on July 1, 2024) were searched. The primary outcomes were postoperative complications and mortality. Secondary outcomes included intraoperative complications, reoperation, readmission, conversion to laparotomy, hospital stay and operation time. Mean difference (MD) or odds ratios (OR) and 95% confidence intervals were calculated. RESULTS: Fifteen studies totaling 33,596 patients were included. There were no differences between nighttime and daytime appendectomy for rates of overall postoperative complications (OR 0.93, 95% CI 0.87, 1.00, 14 studies), mortality (OR 1.70, 95% CI 0.37, 7.88, 7 studies), intraoperative complications (OR 0.88, 95% CI 0.08, 9.86; 2 studies), reoperation (OR 0.39, 95% CI 0.06, 2.55; 3 studies) and readmission (OR 0.86, 95% CI 0.65, 1.13; I2 = 0%, 5 studies). However, the conversion to laparotomy risks (OR 1.92, 95% CI 1.12, 3.29; 6 studies) among patients who underwent appendectomy during nighttime was significantly elevated compared to daytime. CONCLUSIONS: There was no increased risk or difference in postoperative mortality and complication rates associated with nighttime compared with daytime appendectomy. However, future studies should assess the reasons for higher conversion rates during the night.

PURPOSE: Surgery wait times after diagnosis of appendicitis are an important factor influencing the success of a patient's treatment. The proposed study will be a quantitative multicenter retrospective cohort design with the primary aim of assessing the difference between appendicectomy wait times between rural and urban hospitals in Western Australia and the effect of this on operative outcomes. Selected outcome measures will be examined by time from initial presentation at an emergency department to the patient being diagnosed and then time of diagnosis to surgery being performed. The secondary aim is to compare rates of negative appendicectomies between hospitals. METHODS: Appendicectomy patients will be identified from operating room register by medical student data collectors; then, each respective hospital's emergency room data collection will subsequently be accessed to complete case report forms based on demographics and clinical findings, pre-operative investigations, and management and follow-up. Case report forms with > 95% completeness will be accepted for pooled analysis. The expected duration of retrospective data collection will be 8 months. This study RGS6483 has received HREC approval by the Royal Perth Hospital HREC Ethics Committee, with a waiver of consent obtained and the HREC was notified of amendments to the protocol made on April 21, 2024. Dissemination of results. Data will be collected and stored online through a secure server running the Research Electronic Data Capture (REDCap) web application. No patient-identifiable data will be entered into the system. Results will subsequently be shared via scientific journal publication and presentation at relevant meetings.
