Abstract
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.

Alajaimi J, Almansoor M, Almutawa A, Almusalam MM, Bakry H. Are Antibiotics the New Appendectomy? Cureus 2023; 15:e44506.

Abstract
Prior to the development of laparoscopic procedures, open appendectomy was the standard of care for the majority of appendicitis cases. Recently, studies have debated using antibiotics as a first-line treatment in uncomplicated appendicitis cases. The definition of uncomplicated appendicitis is not always clear-cut; however, with the large-scale accessibility of radiologic techniques, it is becoming increasingly easier to classify patient groups. As suggested by clinical and radiological patient data, this has raised the speculation of considering antibiotic therapy as the sole treatment modality in uncomplicated appendicitis cases. We aim to compare the options of surgery and antibiotics only in terms of efficacy, complications, and financial cost. A range of databases and search strategies were adopted, and various databases were used, including PubMed, ScienceDirect, Google Scholar, and JAMA. Collectively, 30 studies were reviewed, but only 18 were included. Efficacy rates were higher in the appendectomy group. Nevertheless, the antibiotics-only group maintained an efficacy rate greater than 70% at one-year follow-up. Risk factors that decreased the efficacy in medical management included the presence of appendicolith, neoplasm, appendiceal dilatation, peri-appendiceal fluid collection, higher mean temperature, CRP, and bilirubin. Complications were more frequent and significant in the surgery group. These included complications related to anaesthesia, surgical site infections, damage to nearby structures, and pulmonary embolism. Despite several years of follow-up and disease recurrences, higher financial costs were observed in surgically treated patients compared to the antibiotics-only group. Given the high success rates post-appendectomy for acute appendicitis over the decades, the efficacy of conservatively treated acute appendicitis raises a strong argument when choosing one of the two options. The efficacy remained consistently higher across the literature in the surgery group than in the antibiotics-only group. However, it is still arguable that antibiotics may be a preferable option given an efficacy rate of more than 70% at one year and overall higher complications associated with surgery. The argument of missing a neoplasm by avoiding surgery is valid. However, most are carcinoid neuroendocrine neoplasms with a low probability of metastasis (<5%) and are usually considered benign. Given the current practice focused on conservative and minimally invasive treatments and recently the COVID-19 pandemic, with its restrictions and lessons learnt, antibiotics may be the future standard for treating uncomplicated acute appendicitis. Lastly, we noticed higher efficacy rates in articles published recently than those published at least five to ten years earlier. Antibiotics-only therapy for uncomplicated appendicitis is cost-effective with fewer complications than surgery. However, appendectomies have higher efficacy. Thus, surgical treatment prevails as the standard of care. Future literature should yield larger sample sizes and explore the numbers of emergency appendectomies mandated following antibiotics-only therapy.

Abstract
BACKGROUND Appendicitis is the most common abdominal surgical emergency worldwide, and its burden has been changing. We report the level and trends of appendicitis prevalence, and incidence; and years lived with disability (YLD) in 204 countries and territories from 1990 to 2019, based on data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHODS The numbers and age-standardized prevalence, incidence, and YLD rates per 100,000 population of appendicitis were estimated across regions and countries by age, sex, and sociodemographic index (SDI). All the estimates were reported with 95% uncertainty intervals (UIs). RESULTS Globally, the age-standardized prevalence and incidence rates of appendicitis in 2019 were 8.7 (95% UI 6.9 to 11.0) and 229.9 (95% UI 180.9 to 291.0) per 100,000 population, with increases of 20.8% (95% UI 18.9 to 23.0%) and 20.5% (95% UI 18.7 to 22.8%) from 1990 to 2019, respectively. Additionally, the age-standardized YLDs rate was 2.7 (95% UI 1.8 to 3.9) in 2019, with an increase of 20.4% (95% UI 16.2 to 25.1%) from 1990 to 2019. In 2019, the age-standardized prevalence, incidence, and YLD rates peaked in the 15-to-19-year age groups in both male and female individuals. However, no statistically significant differences were observed between the male and female individuals in all groups. Ethiopia, India, and Nigeria showed the largest increases in the age-standardized prevalence rate between 1990 and 2019. Generally, positive associations were found between the age-standardized YLD rates and SDI at the regional and national levels. CONCLUSIONS Appendicitis remains a major public health challenge globally. Increasing awareness of appendicitis and its risk factors and the importance of early diagnosis and treatment is warranted to reduce its the burden.

Abstract
The frequent abdominal surgical emergency is acute appendicitis with a significantly less lifelong risk. One of the most common surgeries manifested is an appendectomy, but with recent advances, non-operative management has evolved using antibiotics. In adult patients with simple appendicitis, we identified the role of surgical and non-surgical therapy. One of the most common surgeries manifested is an appendectomy, but with recent advances, non-operative management has evolved using antibiotics. In adults suffering from mild appendicitis, we identified the role of surgical and non-surgical therapy. The analysis indicated that the Antibiotics versus Primary Appendectomy in Children (APAC) did not establish non-inferiority of antibiotics vs. appendectomy with a pre-specified small margin. In contrast to the majority of appendectomies that are carried out laparoscopically, the surgeries were almost usually open. Appendectomies, both laparoscopic and open, are not the same procedure. Antibiotic therapy is effective in about 60% of cases of simple appendicitis. A surgery-only strategy would reduce antibiotic exposure, a factor to consider in these days of antimicrobial stewardship. Therefore, studies are being conducted on whether to shift alone on antibiotics or with appendectomy to have better results with fewer complications. Future studies should focus on appendicitis features and long-term unfavorable consequences, including antibiotic resistance or Clostridium difficile colitis, most responsive to antibiotics by utilizing laparoscopic procedures as controls. Using it along with appendectomy may change the outcome showing a better prognosis.

Abstract
PURPOSE Interval appendectomy following nonoperative management of complicated appendicitis remains controversial. The aim of this study was to evaluate surgical pathology and clinical outcomes after pediatric interval appendectomy. METHODS Pathology results from children with complicated appendicitis who underwent interval appendectomy at a single children's hospital from 2010 to 2017 were reviewed. The primary outcome was pathology results. Secondary outcomes included complications and readmission following initial treatment and after interval appendectomy. RESULTS Among 149 patients (median age 11 years; range, 1-18), all had evidence of persistent inflammation on surgical pathology, 25 (17%) had an appendicolith, and no neoplasms were identified. Median duration of the initial admission was 8 days (range, 2-28) and 70% received a percutaneous drain prior to appendectomy. Interval appendectomy was performed at a median of 7.5 weeks (range, 2.9-29.1). Thirty-six (24%) returned to the hospital prior to their scheduled appendectomy and 6 (4%) required appendectomy earlier than planned. Nine patients (6%) experienced a complication following interval appendectomy, of which superficial surgical site infection was the most common (n = 4). CONCLUSION All children had evidence of ongoing inflammation on surgical pathology. While the clinical implications of persistent inflammation remain uncertain, these findings suggest that interval appendectomy is an appropriate treatment following medical management of complicated appendicitis in children. LEVEL OF EVIDENCE SECTION IV, Case series with no comparison groups.

Abstract
Background: Early and accurate identification or exclusion of acute appendicitis is the key to avoid the morbidity of delayed treatment for true appendicitis or unnecessary appendicectomy, respectively. We aim (i) to identify potential predictive factors for positive and negative appendicectomies; and (ii) to analyse the use of ultrasound scans (US) and computed tomography (CT) scans for acute appendicitis. Materials and Methods: All appendicectomies that took place at our hospital from the 1st of January 2013 to the 31st of December 2015 were retrospectively recorded. Test results of potential predictive factors of acute appendicitis were recorded. Statistical analysis was performed using Fisher exact test, logistic regression analysis, sensitivity, specificity, and positive and negative predictive values calculation. Results: 208 patients were included in this study. 184 patients had histologically proven acute appendicitis. The other 24 patients had either nonappendicitis pathology or normal appendix. Logistic regression analysis showed statistically significant associations between appendicitis and white cell count, neutrophil count, C-reactive protein, and bilirubin. Neutrophil count was the test with the highest sensitivity and negative predictive values, whereas bilirubin was the test with the highest specificity and positive predictive values (PPV). US and CT scans had high sensitivity and PPV for diagnosing appendicitis. Conclusions: No single test was sufficient to diagnose or exclude acute appendicitis by itself. Combining tests with high sensitivity (abnormal neutrophil count, and US and CT scans) and high specificity (raised bilirubin) may predict acute appendicitis more accurately.

Abstract
PURPOSE OF REVIEW The aim of this review is to summarize the recent literature investigating nonoperative management of uncomplicated and complicated appendicitis and highlight recent data establishing its safety and efficacy. RECENT FINDINGS Recent studies and clinical trials have demonstrated the efficacy of nonoperative treatment of both uncomplicated and complicated appendicitis, defined as perforated appendicitis with or without formed abscess or phlegmon. Nonoperative management of uncomplicated appendicitis has been reported to be effective in approximately 71-94% of cases. In complicated appendicitis, treatment with antibiotics alone or antibiotics with interval appendectomy has been shown to be a well tolerated and reasonable treatment alternative. SUMMARY Appendicitis is one of the most common surgical diagnoses in children. The standard of care for many years has been surgical appendectomy; however, it carries with it risks including bleeding, wound complications, injury to surrounding structures, and the potential need for reoperation. Nonoperative management of both uncomplicated and complicated appendicitis in children is well tolerated and efficacious in select populations.
