Abstract
BACKGROUND Appendicitis is an extremely common disease with a variety of medical and surgical treatment approaches. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians and patients in decisions regarding the diagnosis and treatment of appendicitis. METHODS A systematic review was conducted from 2010 to 2022 to answer 8 key questions relating to the diagnosis of appendicitis, operative or nonoperative management, and specific technical and post-operative issues for appendectomy. The results of this systematic review were then presented to a panel of adult and pediatric surgeons. Evidence-based recommendations were formulated using the GRADE methodology by subject experts. RESULTS Conditional recommendations were made in favor of uncomplicated and complicated appendicitis being managed operatively, either delayed (>12h) or immediate operation (<12h), either suction and lavage or suction alone, no routine drain placement, treatment with short-term antibiotics postoperatively for complicated appendicitis, and complicated appendicitis previously treated nonoperatively undergoing interval appendectomy. A conditional recommendation signals that the benefits of adhering to a recommendation probably outweigh the harms although it does also indicate uncertainty. CONCLUSIONS These recommendations should provide guidance with regard to current controversies in appendicitis. The panel also highlighted future research opportunities where the evidence base can be strengthened.

Abstract
INTRODUCTION Appendiceal neoplasms (ANs) are rare, with an estimated incidence of around 1%: neuroendocrine tumours (NETs) and low-grade appendiceal mucinous neoplasms (LAMNs) comprise most cases. Most tumours are cured by appendectomy alone, although some require right hemicolectomy and intra-operative chemotherapy. The aim of the present study is to evaluate our institution's experience in terms of the prevalence of AN, their histological types, treatment and outcomes in adult patients undergoing emergency appendectomy. MATERIAL AND METHODS Single-centre retrospective cohort analysis of patients treated for acute appendicitis at a large academic medical centre. Patients with a diagnosis of acute appendicitis (AA) where further compared with patients with acute appendicitis and a histologically confirmed diagnosis of appendiceal neoplasm (AN). RESULTS A diagnosis of acute appendicitis was made in 1200 patients. Of these, 989 patients underwent emergency appendectomy. The overall incidence of appendiceal neoplasm was 9.3% (92 patients). AN rate increased with increasing age. Patients under the age of 30 had a 3.8% (14/367 patients) rate of occult neoplasm, whereas patients between 40 and 89 years and older had a 13.0% rate of neoplasm. No difference was found in clinical presentations and type of approach while we found a lower complicated appendicitis rate in the AN group. CONCLUSION ANs are less rare with respect to the literature; however, clinically, there are no specific signs of suspicious and simple appendicectomy appears to be curative in most cases. However, age plays an important role; older patients are at higher risk for AN. ANs still challenge the non-operative management concept introduced into the surgical literature.

Abstract
Recent studies have discussed the role of antibiotic treatment in the conservative management of acute appendicitis and whether antibiotics are a safe option to replace appendicectomy, which has been the gold standard treatment of acute appendicitis for many years. The bibliographic databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane, Embase, Medline, and PubMed comparing conservative versus surgical treatment of acute appendicitis were systematically searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Twenty-one studies consisting of systematic reviews and meta-analyses involving 44,699 participants were identified. At least 17,865 participants were treated with antibiotics. Our studies compare antibiotic versus appendicectomy among acute appendicitis patients ranging from 7 to 94 years of age. In most studies, patients received parenteral antibiotics for a total of one to three days, and oral antibiotics such as oral cephalosporin plus metronidazole, oral amoxicillin/clavulanate, oral fluoroquinolones plus Tinidazole upon hospital discharge for a total of 7 to 10 days. The total course of antibiotics for both parenteral and oral regimes ranged from 2 to 16 days, with 10 days being the commonest duration. The recurrence rate following initial antibiotic treatment at one-year follow-up ranged from 13% to 38%, while the mean duration of recurrence ranged from three to eight months. The majority of the patients with recurrence underwent appendicectomy, while some patients were either given a repeat or different course of antibiotics due to the possible presence of antibiotic resistance; however, only 2.4% of the patients were successfully treated upon completion of the second course of antibiotics. Most of the studies concluded that appendicectomy remains the gold standard treatment for uncomplicated acute appendicitis, given its higher efficacy and lower complication rates. Although antibiotic treatment cannot be routinely recommended, it can be considered an appropriate alternative in selected patients with uncomplicated appendicitis who wish to avoid surgery and also acknowledge the risk of recurrence and the potential need for subsequent surgery at the same time.

Abstract
INTRODUCTION Making healthcare decisions for children can be challenging for parents or guardians. We aimed to characterize the decision-making preferences and stress of parents or guardians who were offered both appendectomy or nonoperative management (NOM) for children with acute appendicitis. METHODS Criteria was developed for offering operative or NOM for patients. At the time of decision, parents or guardians completed a survey assessing their understanding of treatment options, stress and preferences in being given the choice. An outpatient follow-up survey was later administered to evaluate post-decision satisfaction. RESULTS A total of 45 respondents were included in the study. More than 95% endorsed understanding of the risks/benefits of the options and felt supported and satisfied with their decision. Half felt the process was more than minimally stressful, 77% felt the decision was easy to make, 89% liked being asked and 95% preferred to make the decision themselves with varying degrees of input from their physician. Of the 62% of parents or guardians who completed the follow-up survey, >90% were satisfied with their decision and one respondent regretted their choice. DISCUSSION When offered the choice between operative and NOM of acute appendicitis, half of parents or guardians felt greater than minimal stress. The majority endorsed adequate understanding of the options, felt it was an easy decision, and maintained the desire to be the primary decision maker for their child. Our study provides preliminary data on parental or guardian attitudes towards shared decision-making in the surgical setting. Follow-up studies should focus on identifying predictors for those who feel increased stress and difficulty with decision-making. LEVEL OF EVIDENCE III.

A Systematic Review Comparing Nonoperative Management to Appendectomy for Uncomplicated Appendicitis in Children. Cureus 2021; 13:e18901.

Abstract
More than a century after its introduction, appendectomy has remained the gold standard treatment for acute appendicitis. In adults with acute uncomplicated appendicitis, nonoperative management (NOM) has been shown to be a viable treatment option. To date, there has been relatively limited data on the nonoperative management of acute appendicitis in the pediatric population. The primary objective of this study was to systematically review the available literature in the pediatric population and compare the efficacy and recurrence between initial nonoperative treatment strategy and appendectomy in children with uncomplicated appendicitis. In July 2021, we conducted systematic searches of the PubMed and Google Scholar databases. We only included full-text comparative original studies published within the last decade, and we excluded articles that solely examined NOM without comparing it to appendectomy. Two writers worked independently on the data collection and analysis. It was found that NOM had a high initial success rate and a low rate of recurrent appendicitis. After months of follow-up, the vast majority of patients with uncomplicated acute appendicitis who received initial nonoperative treatment did not require surgical intervention. Furthermore, the rate of complication was comparable in both treatment groups, and NOM did not appear to be associated with an increased risk of complications. The most significant drawback stemmed from the fact that the included articles in this study had a wide range of study designs and inclusion criteria. According to current evidence, NOM is feasible and cost-effective. Antibiotic therapy can be given safely in a small subset of individuals with uncomplicated appendicitis. To optimize outcomes, physicians should evaluate the clinical presentation and the patient's desire when selecting those to be managed nonoperatively. Again, more research, preferably large randomized trials, is required to compare the long-term clinical efficacy of NOM with appendicectomy. Finally, additional research is required to establish the characteristics of patients who are the best candidates for nonoperative treatment.

Abstract
BACKGROUND The aim of this study is to investigate the outcomes of conservative management of non-complicated acute appendicitis (AA) using our unique institutional protocol, and to compare between these and the outcomes of operative management. METHODS Patients admitted to our institution between March 2016 and October 2019 with non-complicated AA were grouped according to their initial management: non-operative versus surgical. Our unique protocol for non-operative management includes: pain < 3 days; afebrile upon admission; non-gravid; WBC <15,000 (× 109/L); CRP < 5 mg/dl; appendix diameter < 1 cm; no appendicolith on imaging; no prior episode of AA; no history of Inflammatory Bowel Disease; no evidence of peritonitis on physical examination. The primary outcome measured was failure of non-surgical management during the index admission. Secondary outcomes included recurrence rate, readmissions, complications, length of antibiotic treatment and length of stay (LOS). RESULTS A total of 695 patients were included, 436 in the operative group and 259 in the non-surgical treatment group. The mean follow-up time was 1004.9 ± 205.7 days. Patients initially treated conservatively rarely required surgery during their index admission (6.9%). Recurrence rate was 19.1% after a mean follow up of 33.4 months. The overall failure rate of conservative management was documented in 20.8% of the patients. The complication rate was higher in those treated with upfront surgery (1.6% vs. 0.4%, p < 0.001). The overall LOS was not statistically different between the groups. CONCLUSIONS Our composite protocol for non-surgical management of non-complicated AA results in a low failure rate. A well calculated patient treatment allocation in non-complicated AA can advocate for wide-spread use of the conservative approach.

Abstract
BACKGROUNDS In cancer patients, the optimal appendicitis treatment has not been established. Therefore, we aimed to determine the ideal treatment option for appendicitis in cancer patients. METHODS This retrospective study included 185 cancer patients with acute appendicitis who were divided into the early surgical group (n = 152) involving surgery performed within 48 h following the appendicitis diagnosis or the conservative group (n = 33) involving intravenous antibiotics. We compared the appendicitis treatment efficacy between the groups. RESULTS In the early surgical group, the antibiotic duration [5.5 days (4.0-8.0) vs. 17.0 days (12.5-25.0), p < 0.001] and hospital stay length [7.0 days (5.0-11.75) vs. 10.0 days (8.0-32.0), p < 0.001] were significantly shorter. Regarding pathology, 16/171 (9.4%) patients who underwent surgery exhibited appendiceal tumours. During the 1-year follow-up period, one recurrence occurred in each group [1/152 (0.7%) vs. 1/33 (3.0%), p = 0.326]. The 1-year treatment success rate was higher in the early surgical group [99.3% (151/152) vs. 42.4% (14/33), p < 0.001]. CONCLUSION Early surgical treatment yielded a significantly higher success rate than conservative treatment for appendicitis in cancer patients. Surgery for appendicitis in cancer patients should be considered not only for treatment but also for pathologic confirmation.

Abstract
Background: Appendicitis is the most common operative emergency in children. As a result of accumulating evidence from randomized trials, observational studies, database work, and meta-analyses, the management of appendicitis in children has been shifting the past 15 years with many new debates emerging. In this article, we review our current management schemes. Methods: We reviewed the current and critical literature relevant to the rationale for our current management. Results: Clinical pathways appear to reduce variation and cost while improving the ability to diagnose and treat the disease. Minimally invasive approaches can be used to treat all forms of appendicitis. Conclusions: The future role of non-operative management deserves ongoing exploration. Refining diagnostic treatment algorithms and enhancing antibiotic stewardship are important moving forward.

Abstract
Appendicitis is a common condition in childhood and adolescence that frequently requires urgent surgical intervention. For almost two centuries appendicitis has been recognized as a medical problem with a surgical solution. Currently the appendix can be removed with a minimally invasive approach, low anesthetic and surgical risk, and swift hospital discharge. Despite these advances, surgery and anesthesia have associated risks including postoperative infection, bleeding, hernia and organ injury among others. In addition, surgery requires time off of school and work to recover and associated healthcare costs can be significant. In both adult and pediatric populations, quality data suggesting a nonoperative approach is suggesting a change to the traditional surgical paradigm. Adults studies have demonstrated both safety and efficacy in the nonoperative management of acute appendicitis. In selected children with uncomplicated appendicitis, initial nonoperative management has been shown to be safe with fewer complications, fewer disability days and less healthcare costs while avoiding the risks inherent to surgery. Ongoing randomized controlled clinical trials in both the United States and Europe seek to further demonstrate the safety of nonoperative management and assist physicians with educating patients about the risk profile of their treatment decision. In complicated appendicitis presenting with abscess or acute appendiceal phlegmon, an initial nonoperative strategy with or without abscess drainage followed by interval appendectomy is the current state of the art though the utility of interval appendectomy is questioned.

Abstract
BACKGROUND Although appendicectomy is still the classical and standard treatment for acute appendicitis, initial conservative antibiotic only treatment for simple uncomplicated cases has been proposed and tried as a feasible and effective approach. The objective of this study was to evaluate the efficacy and outcomes of antibiotics treatment for acute simple uncomplicated appendicitis. METHODS This is a prospective controlled nonrandomized study in which a total of 156 patients whose ages range from 16 to 54 years presenting with clinical diagnosis of acute uncomplicated appendicitis were assigned for conservative antibiotics treatment, which consists of ceftriaxone I gram twice daily and metronidazole infusions, 500 mg in 100 ml, 3 times daily for 48 to 72 hours to be converted on oral antibiotics after clinical improvement for 5 to 7 days. Patients who failed to initial conservative treatment and those who had recurring symptoms of appendicitis were presented for appendectomy. RESULTS Antibiotic treatment was successful and feasible in 138 (88.5%) patients. Progression of the signs and symptoms despite full medical treatment was observed in 11 (7%) patients during the same admission. Further 7 (4.5%) patients showed recurrence of the symptoms during follow-up period of 6-12 months after successful initial conservative treatment and also proceeded for appendicectomy. CONCLUSION Nonoperative antibiotic treatment of acute simple appendicitis is safe, feasible, and effective for properly selected cases, thus avoiding unnecessary surgery with its possible complications.

Abstract
Abstract
Introduction Acute appendicitis is the most common surgical disease of the abdomen in clinical practice, affecting mainly young adults. It has a wide variety of clinical presentations, due to the anatomical variation of the cecal appendix. Its presentation as acute scrotum and scrotal abscess is quite rare and atypical, occurring mainly in young male patients with patent processus vaginalis.
Case presentation An 18-years-old male patient attended the emergency unit complaining of diffuse abdominal pain, fever and hyporexia for four days followed by inflammatory signs in the scrotum. He was taken to the operation room after diagnosis of scrotal and abdominal sepsis. During scrotum exploration, pus was found inside the right hemiscrotum coming down from the groin and communicating with the abdominal cavity. The laparotomy found perforated appendicitis and peritonitis leading to the scrotal abscess. The abscess was drained, appendectomy was performed and the scrotal and abdominal cavity were washed with saline solution. Despite postoperative complications such as pneumonia and intra-abdominal abscess, the reported patient recovered and was discharged in the 44th postoperative day.
Conclusion Acute appendicitis can mimic acute scrotum and surgeons must have a high index of suspicion of this complication for diagnosing. This unusual clinical presentation may be challenging and can delay the diagnosis leading to perforated peritonitis.

Abstract
INTRODUCTION During the past decade, nonoperative management (NOM) for simple acute appendicitis (SAA) in children has been proven safe with noninferior complications rate. The aim of this study was to examine Alvarado score and pediatric appendicitis score (PAS) together with other factors in predicting failure of NOM in children presenting with SAA. MATERIALS AND METHODS Patients aged 5 to 18 years admitted to our department between 2017 and 2019 diagnosed with SAA were given a choice between surgical management and NOM. We divided the NOM patients into two groups: successful treatment and failed NOM, comparing their files for Alvarado score and PAS and other clinical and demographic factors, with a mean follow-up of 7 months. Failure was determined as need for appendectomy following conservative treatment due to any reason. RESULTS A total of 85 patients answered criteria and chose NOM. Overall failure rate was 32.9%. We found no difference in the mean Alvarado score and PAS as well as in each component of both scores between success and failed NOM groups. However, when using the risk classification of the scores, we found a significant correlation between high-risk Alvarado score and failed NOM. After adjusting for age, gender, duration of symptoms, diagnosis of tip appendicitis, and presence of appendicolith, the odds of failure were four times higher among high-risk Alvarado group. CONCLUSION Alvarado score of 7 or higher, older age, and diagnosis of an appendicolith on imaging are possible predictors for failure of NOM for SAA in children.

Abstract
BACKGROUND The impact of laparoscopic appendectomy (LA) on the incidence of intra-abdominal abscess (IAA) remains controversial. We aimed to identify risk factors for postappendectomy IAA and assess the impact of appendectomy approach in postoperative morbidity. METHODS A retrospective single-center study including consecutive patients who underwent appendectomy for acute appendicitis between 2015 and 2018 was performed. Demographic, clinical, intraoperative, and perioperative variables were collected. Univariate and multivariate analyses was performed to detect independent risk factors for IAA. Comparison of LA and open appendectomy was conducted, and propensity score model (PSM) was used to overcome differences between groups. Independent risk factors for IAA were identified by univariate and multivariate analyses in the PSM cohort. RESULTS A total of 532 appendectomies were included. The median age was 35 years. Three hundred two patients (56.7%) underwent LA. The most frequent operative finding was American Association for the Surgery of Trauma (AAST) grade 1 appendicitis in 303 patients (57%). Peritonitis was found in 109 patients (20.5%). Postoperative morbidity and mortality were 14.4% and 0%, respectively. Intra-abdominal abscess rate was 6.2%. An AAST grade of ≥2, a preoperative C-reactive protein level of >100 mg/dL, and diabetes mellitus were identified as independent risk factors for IAA in the multivariate analysis. Comparing LA and open appendectomy, there were no differences in IAA rates. After PSM, LA showed lower morbidity and shorter hospital stay. CONCLUSIONS Laparoscopic appendectomy is a safe approach and not related to a higher risk of IAA. Patients with an AAST grade of ≥2, a preoperative C-reactive protein level of >100, and diabetes mellitus have higher risk for postappendectomy IAA.

Abstract
Can Uncomplicated Adult Appendicitis Also Be Treated Conservatively? Abstract. For more than a century, appendectomy has been the first-line treatment for acute appendicitis. Despite modern imaging, it is not an easy disease to diagnose and is one of the most common emergency procedures worldwide. Conservative therapy for uncomplicated adult appendicitis is increasingly becoming the focus of discussion. Due to current data, a recommendation for conservative therapy of uncomplicated adult appendicitis can not be given. For the time being it should be reserved for a selected patient group.

Abstract
BACKGROUND In our institution, we avoid emergency nighttime appendectomies, instead performing the surgery during daylight hours the following day. We examined whether emergency or early appendectomies affect the outcome of patient morbidity. MATERIALS AND METHODS Medical records of children treated for appendicitis between 2010 and 2012 were retrospectively reviewed. Outcomes were compared between Group 1, defined as those patients who presented to the hospital during the day and underwent appendectomy on the same day and Group 2, defined as those patients who presented to the hospital at night and underwent appendectomy the next day. Incidences of perforation at surgery, operative time, complications and length of stay were analysed. Cases with perforation were also analysed to determine if the perforations could have been identified preoperatively. RESULTS A total of 74 patients met the study criteria, including 41 and 33 in Groups 1 and 2, respectively. There were no significant differences in the incidence of perforation at surgery, operative time, complications and length of stay. A total of nine cases of perforation were identified during surgery, and there were no significant differences in the pre-operative characteristics between perforated and non-perforated cases. CONCLUSIONS The results of this study indicate that early appendectomy is safe and did not increase patient morbidity. We, therefore, recommend performing appendectomies in the daytime.

Abstract
Appendicectomy has been accepted as the gold standard for the management of appendicitis over the years, but there has been an increasing evidence and trend toward the conservative approach to the management of appendicitis. The aim of this review is to search existing literature and to evaluate and compare the conservative and operative approaches to the management of appendicitis. An electronic search of published literature was conducted through Pubmed, Google Scholar, Embase, and Medline using a variety of search items to find relevant observational studies, randomized clinical trials, systematic reviews, and meta-analyses. Bibliographies of selected articles were also analyzed for publications of interest relevant to the scope of the topic. The articles that reported primary outcomes after the management of appendicitis, complications, economic implications, and duration of follow-up were reviewed in detail. The major primary outcomes show a high recurrence rate and failed treatment associated with the conservative management of appendicitis. The other outcomes obtained show that there is an increased incidence of complications associated with operative management. Economic implications and cost-effectiveness analysis show that conservative treatment may be preferred. The length of hospital stay was significantly higher in conservative approach to management; however, shorter time off activities was observed. In general, the conservative management of appendicitis is still regarded as safe, effective, and efficacious, and further research with well-constructed study design, and larger sample size is required.

Abstract
For decades, the mandatory treatment for acute uncomplicated appendicitis was urgent appendicectomy. This dogma has now been questioned by several randomized controlled trials, which demonstrated the safety of antibiotic treatment of uncomplicated appendicitis without increased morbidity and mortality. The efficacy of this conservative treatment, however, is inferior to surgery: Within the first year after antibiotic treatment of acute appendicitis, approximately 30% of patients require appendicectomy. Within 5 years the rate of appendicectomy increases to 40% and the life-long risk of appendicectomy after conservative treatment can be expected to be even higher. The advantages of conservative treatment of appendicitis are faster recovery and the lack of postoperative wound pain; however, all currently available trials compared conservative treatment almost exclusively with conventional appendicectomy, trials comparing laparoscopic appendicectomy to antibiotics are currently not available. As laparoscopic appendicectomy is a well-established and safe treatment ubiquitously available in Germany, conservative treatment in patients with uncomplicated appendicitis cannot generally be recommended. As antibiotic treatment is a less effective but equally safe procedure, it can be offered to selected patients only.

Abstract
Traditionally, children presenting with appendicitis are referred for urgent appendectomy. Recent improvements in the quality and availability of diagnostic imaging allow for better pre-operative characterization of appendicitis, including severity of inflammation; size of the appendix; and presence of extra-luminal inflammation, phlegmon, or abscess. These imaging advances, in conjunction with the availability of broad spectrum oral antibiotics, allow for the identification of a subset of patients with uncomplicated appendicitis that can be successfully treated with antibiotics alone. Recent studies demonstrated that antibiotics alone are a safe and efficacious treatment alternative for patents with uncomplicated appendicitis. The objective of this study is to perform a multi-institutional trial to examine the effectiveness of non-operative management of uncomplicated pediatric appendicitis across a group of large children's hospitals. A prospective patient choice design was chosen to compare non-operative management to surgery in order to assess effectiveness in a broad population representative of clinical practice in which non-operative management is offered as an alternative to surgery. The risks and benefits of each treatment are very different and a "successful" treatment depends on which risks and benefits are most important to each patient and his/her family. The patient-choice design allows for alignment of preferences with treatment. Patients meeting eligibility criteria are offered a choice of non-operative management or appendectomy. Primary outcomes include determining the success rate of non-operative management and comparing differences in disability days, and secondarily, complication rates, quality of life, and healthcare satisfaction, between patients choosing non-operative management and those choosing appendectomy.

Abstract
Importance Strategies to activate and engage patients and caregivers in shared decision making in the acute care setting may result in improved outcomes. Objective To determine whether a patient activation tool (PAT) can improve decision-making and patient-centered outcomes among pediatric patients and their caregivers who choose between surgery and nonoperative management for their child's appendicitis. Design, Setting, and Participants This single-blind, randomized clinical trial collected data from a single tertiary children's hospital from March 1, 2014, through April 30, 2016, with 1-year follow-up completed on May 1, 2017. Two hundred of 236 eligible children and adolescents aged 7 to 17 years with uncomplicated appendicitis enrolled with their caregivers. After receiving the randomized clinical intervention, caregivers chose surgery or nonoperative management. Data were analyzed from March 1, 2014, through May 1, 2017. Interventions Randomization to a scripted standardized surgical consultation that emphasized patient choice or a scripted standardized surgical consultation plus the PAT (a tablet-based tool that presents each treatment, encourages participation in medical decision making, and aims at alleviating decisional uncertainty). Main Outcomes and Measures Decisional self-efficacy immediately after treatment decision, health care satisfaction at discharge, and disability days for the child at 1-year follow-up. Results Among 200 participants (median age, 12 years [interquartile range (IQR), 9-15 years]; 120 [60.0%] male), 98 were randomized to the PAT and 102 to the standardized consultation groups. The percentages choosing nonoperative management were similar (standardized consultation group, 42 of 102 [41.2%]; PAT group, 31 of 98 [31.6%]; P = .19). Immediate decisional self-efficacy was similar in the standardized consultation and PAT groups (median score, 100 [IQR, 97.7-100] vs 100 [IQR, 95.5-100]; P = .03), which was not significant at the planned significance level of P = .02. Total scores on health care satisfaction at discharge were similar (median, 99 [IQR, 94.7-100] vs 98 [IQR, 91.7-100]; P = .27). Disability days at 1-year follow-up were also similar (median, 6 [IQR, 2-11] vs 5 [IQR, 2-15]; P = .67). No difference in the failure rate of nonoperative management at 1 year (13 of 38 [34.2%] vs 11 of 30 [36.7%]; P > .99) or in the rate of complicated appendicitis 30 days after discharge (7 of 68 [10.3%] vs 9 of 71 [12.7%]; P = .79) occurred. Conclusions and Relevance In this study, a technology-based PAT did not improve measures of decision making for pediatric patients and caregivers needing to make an urgent treatment decision between surgery and nonoperative management for appendicitis. However, the overall high scores in both groups suggest that pediatric patients and caregivers can process information in the acute care setting and effectively participate in an informed shared decision-making process around the need for surgery.

Abstract
BACKGROUND Meta-analyses and a recent guideline acknowledge that conservative management of uncomplicated appendicitis with antibiotics can be successful for patients who wish to avoid surgery. However, guidance as to specific management does not exist. METHODS PUBMED and EMBASE search of trials describing methods of conservative treatment was conducted according to Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. RESULTS Thirty-four studies involving 2,944 antibiotic-treated participants were identified. The greatest experience with conservative treatment is in persons 5 to 50 years of age. In most trials, imaging was used to confirm localized appendicitis without evidence of abscess, phlegmon, or tumor. Antibiotics regimens were generally consistent with intra-abdominal infection treatment guidelines and used for a total of 7 to 10 days. Approaches ranged from 3-day hospitalization on parenteral agents to same-day hospital or ED discharge of stable patients with outpatient oral antibiotics. Minimum time allowed before response was evaluated varied from 8 to 72 hours. Although pain was a common criterion for nonresponse and appendectomy, analgesic regimens were poorly described. Trials differed in use of other response indicators, that is, white blood cell count, C-reactive protein, and reimaging. Diet ranged from restriction for 48 hours to as tolerated. Initial response rates were generally greater than 90% and most participants improved by 24 to 48 hours, with no related severe sepsis or deaths. In most studies, appendectomy was recommended for recurrence; however, in several, patients had antibiotic retreatment with success. CONCLUSION While further investigation of conservative treatment is ongoing, patients considering this approach should be advised and managed according to study methods and related guidelines to promote informed shared decision-making and optimize their chance of similar outcomes as described in published trials. Future studies that address biases associated with enrollment and response evaluation, employ best-practice pain control and antibiotic selection, better define cancer risk, and explore longer time thresholds for response, minimized diet restriction and hospital stays, and antibiotic re-treatment will further our understanding of the potential effectiveness of conservative management.

Abstract
BackgroundThis study evaluates the validity of Alvarado Score in predicting disease severity and the development of postoperative complications in pediatric appendicitis.MethodsThis is a retrospective, bicentered study on pediatric patients with emergency appendicectomy performed from 2006 to 2016. The relationship of Alvarado Score (low: 1–4, medium: 5–6, high: 7–10) and operative findings/complications was analyzed.ResultsA total of 316 patients were included and the median age on admission was 10.8 years. The overall median score was 8.0. 13.3%, 20.2%, and 66.5% of patients had low, medium, and high risk scores, respectively. 36.1% of patients had complicated appendicitis and the median score was comparable with that of the uncomplicated cases (7.0 vs 7.4, p=0.21). More complicated cases were found in the medium-risk group (high vs medium vs low=29.7% vs 61.4% vs 31.0%, p=0.01). Rebound tenderness had the highest positive predictive value (65%) for complicated appendicitis. Postoperative complications were found in 16.5% of patients with a higher median score (7.87 vs 5.8, p=0.01).ConclusionAlvarado Score does not predict disease severity but postoperative complication. Patients with medium risk score should also be treated promptly for the risk of having complicated disease. Rebound tenderness may be a signal for complicated appendicitis and should be properly examined.

Abstract
Acute appendicitis has been considered by surgeons a progressive disease leading to perforation for more than 100 years. In the last decades the theories about this concept gained attention, especially in adults. However, appendectomy for acute appendicitis remains the most common urgent/emergent surgical procedure. At present, accumulating evidences are showing the changing in clinical practice towards the non-operative management of several cases of acute appendicitis either non-complicated or complicated. The present review aims to show the literature results regarding the non-operative management of acute appendicitis in non-complicated and in complicated cases.

Abstract
Colonoscopy is commonly performed for diagnostic and therapeutic purposes and has a relatively low morbidity rate. Nevertheless, it is necessary for operators to be aware of the rare complications of colonoscopy due to a large number of procedures performed in daily practice. Acute appendicitis is an unusually rare occurrence after colonoscopy, with no clear association being found between the colonoscopy and acute appendicitis. A rapid diagnosis of this complication is possible by widespread awareness in surgeons regarding this condition. Acute appendicitis cannot be reliably resulted in as the cause of acute abdominal pain due to relatively subtle signs, symptoms, and studies performed for bowel perforation. The diagnosis of postcolonoscopy appendicitis is difficult, and strategies for its treatment show significant variation. This report presents a patient having undergone urgent laparotomy within 12 h after colonoscopy on having signs and symptoms of acute appendicitis-induced peritonitis.

Abstract
Nonoperative management of acute appendicitis is becoming widespread, but recurrence and the potential for a complicated course are important concerns. An admission report-based institutional database was created to monitor appendicitis treatment outcomes. Complications and complexity of surgery were recorded based on manual chart review. A cohort of patients spanning one year was analyzed. Initial management was operative in 181 (82%) and nonoperative in 39 (18%) cases. There were no differences in demographics, BMI, or Alvarado score. One operative patient and 17 non-operative patients required additional treatment for recurrence/nonresolution (0.6% vs 44%, P < 0.00001). Twenty-eight (15%) operative patients and 17 (44%) nonoperative patients had complications ( P = 0.0003). Thirty-six (19.9%) operations in the operative group and 8 (53.3%) in the non-operative group were classified as complex ( P = 0.007). Hospital stay was longer in the nonoperative group (one vs two days, P = 0.005). Two incidental malignancies in the operative group and one in the nonoperative group were identified. These results are consistent with prior studies showing that recurrence/nonresolution is common after nonoperative management. For patients with recurrence/nonresolution, surgery may be more complex.

Abstract
PURPOSE To compare the outcome of initially nonoperative treatment with immediate appendectomy for simple appendicitis in children. METHODS Between September 2012 and June 2014 children aged 7-17 years with a radiologically confirmed simple appendicitis were invited to participate in a multicentre prospective cohort study in which they were treated with an initially nonoperative treatment strategy; nonparticipants underwent immediate appendectomy. In October 2015, their rates of complications and subsequent appendectomies, and health-related quality of life (HRQOL) were assessed. RESULTS In this period, 25 children were treated with an initially nonoperative treatment strategy and 19 with immediate appendectomy; median (range) follow-up was 25 (16-36) and 26 (17-34) months, respectively. The percentage [95%CI] of patients experiencing complications in the initially nonoperative group and the immediate appendectomy group was 12 [4-30]% and 11 [3-31]%, respectively. In total 6/25 children (24%) underwent an appendectomy; none of the 6 patients operated subsequently experienced any postappendectomy complications. Overall, HRQOL in the nonoperative treatment group was similar to that of healthy peers. CONCLUSIONS Outcome of initially nonoperative treatment for acute simple appendicitis in children is similar to the outcome in those who undergo immediate appendectomy. Initially nonoperative management seems to be able to avoid appendectomy in 3 out of 4 children. LEVEL OF EVIDENCE 2 (prospective comparative study). This research did not receive any specific grant from funding agencies in the public, commercial or not-for-profit sectors.

Abstract
UPDATE This Living FRISBEE (Living FRIendly Summary of the Body of Evidence using Epistemonikos) is an update of the summary published in January 2016. INTRODUCTION Appendicitis is a typical cause of acute abdominal pain and the most frequent cause of emergency abdominal surgery. In the last two decades, increasing evidence has been published about the use of antibiotics as an exclusive treatment for acute appendicitis. METHODS To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained through searches from multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. We extracted the data from the identified reviews, reanalyzed the data from the primary studies, performed a meta-analysis and prepared a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified 23 systematic reviews including 28 primary studies, of which eight were randomized trials. We concluded the exclusive use of antibiotics for the treatment of uncomplicated acute appendicitis could be less effective than appendectomy, but it might be associated with a lower rate of complications.

Abstract
BACKGROUND Some studies indicate that noncomplicated acute appendicitis might be treated exclusively with antibiotics instead of an appendectomy. This study was undertaken to assess outcomes in elderly veterans and to determine if operative intervention would lead to substantial complications such that a nonoperative strategy should be investigated. METHODS A retrospective, single-institution analysis was conducted of patients who underwent an appendectomy at the VA North Texas Health Care System over a period of 12 years (from July 2005 to June 2017). Patients who underwent an appendectomy for cancer, interval appendectomy, exploratory laparotomy for perforated appendicitis, or appendectomy as part of another major operation were excluded from the study. Patients were then grouped as elderly (≥60 years old) and young (<60 years old), and differences in outcome were assessed. Univariate and multivariate analyses were also performed to determine if age and comorbid conditions were independent predictors of complications in both cohorts. RESULTS Of patients who underwent an appendectomy for acute appendicitis (n = 257, male = 90.7%, age = 45.4 ± standard deviation 15.6 years, body mass index = 30.3 ± 6.3 kg/m2), 195 were young (38.7 ± 11.2 years old) and 62 elderly (66 ± 5 years old). More patients were male in the elderly cohort (98.4% vs 88%; P = .01). The incidence of gangrenous and perforated appendicitis was greater in elderly patients (11.3% and 14.4% vs 24 % and 40%, P < .01 each). Diabetes and hypertension, as well as a history of cardiac, pulmonary, and renal diseases, were more than 2-fold greater in older patients. Complications and 30-day readmission rates were similar in both groups (young vs elderly: 7.2% and 9% vs 9.7% and 11%, P > .5 each). Logistic regression analysis showed that age and American Society of Anesthesia level were not independent predictors of complications. A history of cardiac disease and open operation independently predicted complications regardless of age. Unexpected malignancy was 3% in the elderly and 1.5% in the young cohort (P = .6) CONCLUSION: Complicated appendicitis is more common in elderly patients. Appendectomy in elderly veteran patients has a low rate of complications similar to younger patients and the private sector. Operative intervention in this group of patients is not prohibitive. Further studies are needed to determine if nonoperative intervention is noninferior to an appendectomy in this high-risk patient population.

Abstract
The optimal treatment for appendiceal mass formed after appendiceal rupture due to acute appendicitis is surrounded with controversy. The treatment strategy ranges from open surgery (emergency or interval appendectomy), laparoscopic appendectomy, and image-guided drainage, to conservative treatment with or without antibiotics. Nonsurgical treatment (including conservative and drainage treatment), followed by interval appendectomy to prevent recurrence, is the traditional management of these patients. The need for interval appendectomy after a successful conservative or/and image-guided drainage treatment, has recently been questioned as the risk of recurrence is relatively small. Several authors consider that even in cases involving only ambulatory follow-up observation, without interval surgery after conservative management, the recurrence rate and risks of missing underlying pathologies were not high. This article evaluates the minimally invasive treatment modalities in the management of appendiceal mass, risk of undetected serious disease, and the need for interval appendectomy to prevent recurrence.

Abstract
Objective To investigate whether the clinician-performed ultrasonography based on the specific criteria for paediatric appendicitis could decrease the negative appendectomy rate without treatment failure. Methods The study was a retrospective review of paediatric patients with suspected appendicitis who presented at the emergency department of a teaching hospital over a period of 18 months. The clinicians performed the ultrasound and decided whether the patients with suspected appendicitis should be referred to surgery or managed conservatively. The determinative ultrasound criteria were the presence of periappendiceal fat infiltration and/or an obstructing appendicolith. Results The 166 paediatric patients with suspected appendicitis underwent ultrasonography performed by clinicians on weekdays; forty (24.1%) cases with an obstructing appendicolith and/or periappendiceal fat infiltration were treated surgically, and none had a pathologically negative appendectomy, which was significantly lower than the number in the computed tomography scan group (10.4%, 11/106) on weeknights or weekends. The remaining 126 (75.8%) patients without obstructing appendicolith or periappendiceal fat infiltration were treated conservatively, regardless of their appendiceal diameter, and no patients experienced a treatment failure. Conclusions The clinician-performed ultrasonography bases on the strict use of above specific ultrasound criteria to determine treatment strategies for suspected paediatric appendicitis can reduce the negative appendectomies without treatment failure.

Abstract
INTRODUCTION Several European studies suggest that some patients with appendicitis can be treated safely with antibiotics. A portion of patients eventually undergo appendectomy within a year, with 10%-15% failing to respond in the initial period and a similar additional proportion with suspected recurrent episodes requiring appendectomy. Nearly all patients with appendicitis in the USA are still treated with surgery. A rigorous comparative effectiveness trial in the USA that is sufficiently large and pragmatic to incorporate usual variations in care and measures the patient experience is needed to determine whether antibiotics are as good as appendectomy. OBJECTIVES The Comparing Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial for acute appendicitis aims to determine whether the antibiotic treatment strategy is non-inferior to appendectomy. METHODS/ANALYSIS CODA is a randomised, pragmatic non-inferiority trial that aims to recruit 1552 English-speaking and Spanish-speaking adults with imaging-confirmed appendicitis. Participants are randomised to appendectomy or 10 days of antibiotics (including an option for complete outpatient therapy). A total of 500 patients who decline randomisation but consent to follow-up will be included in a parallel observational cohort. The primary analytic outcome is quality of life (measured by the EuroQol five dimension index) at 4 weeks. Clinical adverse events, rate of eventual appendectomy, decisional regret, return to work/school, work productivity and healthcare utilisation will be compared. Planned exploratory analyses will identify subpopulations that may have a differential risk of eventual appendectomy in the antibiotic treatment arm. ETHICS AND DISSEMINATION This trial was approved by the University of Washington's Human Subjects Division. Results from this trial will be presented in international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT02800785.

Abstract
INTRODUCTION Appendectomy has long been the mainstay of intervention for acute appendicitis, aiming at preventing perforation, peritonitis, abscess formation and recurrence. With better understanding of the disease process, non-operative management (NOM) with antibiotics alone has been proved a feasible treatment for uncomplicated appendicitis. This article aimed at systematically reviewing the available literatures and discussing the question whether NOM should replace appendectomy as the standard first-line treatment for uncomplicated appendicitis. METHOD A search of the Embase, Pubmed and Cochrane Library was performed using the keywords 'acute appendicitis' and 'antibiotic therapy'. Meta-analysis with inverse variance model for continuous variable and Mantel Haenzel Model for dichotomous variable was performed to evaluate the one year treatment efficacy, morbidities rate, sick leave duration and length of hospital stay associated with emergency appendectomy and NOM. RESULTS Six randomized control trials were identified out of 1943 publications. NOM had a significant lower treatment efficacy rate at one year, 0.10 (95% CI 0.03-0.36, p < 0.01), when compared to appendectomy. The morbidities rate was comparable between the two interventions. The length of hospital stay was longer, with a mean difference of 1.08 days (95% CI 0.09-2.07, p = 0.03), and the sick leave duration was shorter, a mean difference of 3.37 days (95% CI -5.90 to -0.85 days, p < 0.01) for NOM. CONCLUSION The paradigm remains unchanged, that appendectomy is the gold standard of treatment for uncomplicated appendicitis, given its higher efficacy rate when compared to NOM.

Abstract
PURPOSE Appendectomy has remained the gold standard treatment of acute appendicitis for more than 100years. Nonoperative management (NOM) has been shown to be a valid treatment alternative for acute uncomplicated appendicitis in adults. A systematic review of available evidence comparing operative management (OM) and NOM in children with acute uncomplicated appendicitis was performed. METHODS Systematic searches of MedLine, Embase, and a clinical trial register (https://clinicaltrials.gov/) were performed in March 2016. Only articles that studied NOM for uncomplicated appendicitis in children were included. Data generation was performed independently by two authors, and quality was assessed using the rating schema by the Oxford Centre for Evidence-Based Medicine. RESULTS 15 articles were selected: four retrospective analyses, four prospective cohort studies, four prospective nonrandomized comparative trials and one randomized controlled trial (RCT). Initial success of the NOM groups (a cure within two weeks of intervention) ranged from 58 to 100%, with 0.1-31.8% recurrence at one year. CONCLUSION Although present literature is scarce, publications support the feasibility of further studies investigating NOM of acute uncomplicated appendicitis in children. Higher quality prospective RCTs with larger sample sizes and robust randomization methods, studying the noninferiority of NOM with antibiotics compared with OM are required to establish its utility. LEVEL OF EVIDENCE This manuscript is a systematic review and thus assigned the lowest evidence used from the manuscripts analyzed which is a Level IV.

Abstract
BACKGROUND To compare the risk of complications between initial nonoperative treatment and appendectomy of uncomplicated (simple) appendicitis in children. METHODS Systematic literature search. Eligible for inclusion were both and randomized controlled trials and cohort studies including children in which the outcome of nonoperative treatment of uncomplicated appendicitis was reported with a minimum follow-up period of one year. Two authors extracted data independently and assessed quality. Primary outcome parameter was the percentage of children experiencing complications. Secondary outcomes were early failures, recurrent appendicitis and appendectomies, for all indications and on request. RESULTS Five of the 2051 articles screened were eligible for inclusion, including 147 children (nonoperative treatment) and 173 children (appendectomy) with one year follow-up. Percentage of children experiencing complications ranged from 0 to 13% versus 0-17% for nonoperative and appendectomy, respectively. Nonoperative treatment avoided an appendectomy in 62-81% of the children after one year follow-up. CONCLUSION The evidence base for initial nonoperative treatment of acute uncomplicated appendicitis in children is by far insufficient. It suggests that the percentage of patients experiencing complications in the initial nonoperative treatment group is comparable to the appendectomy group, and it may avoid an appendectomy in the large majority of children after one year follow-up. TYPE OF STUDY Systematic review. LEVEL OF EVIDENCE 1.

Abstract
BACKGROUND An increasing amount of evidence supports antibiotic therapy for treating uncomplicated acute appendicitis. The objective of this study was to compare the costs of antibiotics alone versus appendicectomy in treating uncomplicated acute appendicitis within the randomized controlled APPAC (APPendicitis ACuta) trial. METHODS The APPAC multicentre, non-inferiority RCT was conducted on patients with CT-confirmed uncomplicated acute appendicitis. Patients were assigned randomly to appendicectomy or antibiotic treatment. All costs were recorded, whether generated by the initial visit and subsequent treatment or possible recurrent appendicitis during the 1-year follow-up. The cost estimates were based on cost levels for the year 2012. RESULTS Some 273 patients were assigned to the appendicectomy group and 257 to antibiotic treatment. Most patients randomized to antibiotic treatment did not require appendicectomy during the 1-year follow-up. In the operative group, overall societal costs (€5989·2, 95 per cent c.i. 5787·3 to 6191·1) were 1·6 times higher (€2244·8, 1940·5 to 2549·1) than those in the antibiotic group (€3744·4, 3514·6 to 3974·2). In both groups, productivity losses represented a slightly higher proportion of overall societal costs than all treatment costs together, with diagnostics and medicines having a minor role. Those in the operative group were prescribed significantly more sick leave than those in the antibiotic group (mean(s.d.) 17·0(8·3) (95 per cent c.i. 16·0 to 18·0) versus 9·2(6·9) (8·3 to 10·0) days respectively; P < 0·001). When the age and sex of the patient as well as the hospital were controlled for simultaneously, the operative treatment generated significantly more costs in all models. CONCLUSION Patients receiving antibiotic therapy for uncomplicated appendicitis incurred lower costs than those who had surgery.

Abstract
BACKGROUND Acute appendicitis is the most common abdominal surgical emergency in the United States, with a lifetime risk of 7%-8%. The treatment paradigm for complicated appendicitis has evolved over the past decade, and many cases now are managed by broad-spectrum antibiotics. We determined the role of non-operative and operative management in adult patients with uncomplicated appendicitis. METHODS Several meta-analyses have attempted to clarify the debate. Arguably the most influential is the Appendicitis Acuta (APPAC) Trial. RESULTS According to the non-inferiority analysis and a pre-specified non-inferiority margin of -24%, the APPAC did not demonstrate non-inferiority of antibiotics vs. appendectomy. Significantly, however, the operations were nearly always open, whereas the majority of appendectomies in the United States are done laparoscopically; and laparoscopic and open appendectomies are not equivalent operations. Treatment with antibiotics is efficacious more than 70% of the time. However, a switch to an antimicrobial-only approach may result in a greater probability of antimicrobial-associated collateral damage, both to the host patient and to antibiotic susceptibility patterns. A surgery-only approach would result in a reduction in antibiotic exposure, a consideration in these days of focus on antimicrobial stewardship. CONCLUSION Future studies should focus on isolating the characteristics of appendicitis most susceptible to antibiotics, using laparoscopic operations as controls and identifying long-term side effects such as antibiotic resistance or Clostridium difficile colitis.

Abstract
BACKGROUND Appendectomy is considered the gold standard treatment for acute appendicitis. Recently the need for surgery has been challenged in both adults and children. In children there is growing clinician, patient and parental interest in non-operative treatment of acute appendicitis with antibiotics as opposed to surgery. To date no multicentre randomised controlled trials that are appropriately powered to determine efficacy of non-operative treatment (antibiotics) for acute appendicitis in children compared with surgery (appendectomy) have been performed. METHODS Multicentre, international, randomised controlled trial with a non-inferiority design. Children (age 5-16 years) with a clinical and/or radiological diagnosis of acute uncomplicated appendicitis will be randomised (1:1 ratio) to receive either laparoscopic appendectomy or treatment with intravenous (minimum 12 hours) followed by oral antibiotics (total course 10 days). Allocation to groups will be stratified by gender, duration of symptoms (> or <48 hours) and centre. Children in both treatment groups will follow a standardised treatment pathway. Primary outcome is treatment failure defined as additional intervention related to appendicitis requiring general anaesthesia within 1 year of randomisation (including recurrent appendicitis) or negative appendectomy. Important secondary outcomes will be reported and a cost-effectiveness analysis will be performed. The primary outcome will be analysed on a non-inferiority basis using a 20% non-inferiority margin. Planned sample size is 978 children. DISCUSSION The APPY trial will be the first multicentre randomised trial comparing non-operative treatment with appendectomy for acute uncomplicated appendicitis in children. The results of this trial have the potential to revolutionise the treatment of this common gastrointestinal emergency. The randomised design will limit the effect of bias on outcomes seen in other studies. TRIAL REGISTRATION NUMBER clinicaltrials.gov: NCT02687464. Registered on Jan 13th 2016.

Abstract
IMPORTANCE Antibiotic therapy for acute uncomplicated appendicitis is effective in adult patients, but its application in pediatric patients remains controversial. OBJECTIVE To compare the safety and efficacy of antibiotic treatment vs appendectomy as the primary therapy for acute uncomplicated appendicitis in pediatric patients. DATA SOURCES The PubMed, MEDLINE, EMBASE, and Cochrane Library databases and the Cochrane Controlled Trials Register for randomized clinical trials were searched through April 17, 2016. The search was limited to studies published in English. Search terms included appendicitis, antibiotics, appendectomy, randomized controlled trial, controlled clinical trial, randomized, placebo, drug therapy, randomly, and trial. STUDY SELECTION Randomized clinical trials and prospective clinical controlled trials comparing antibiotic therapy with appendectomy for acute uncomplicated appendicitis in pediatric patients (aged 5-18 years) were included in the meta-analysis. The outcomes included at least 2 of the following terms: success rate of antibiotic treatment and appendectomy, complications, readmissions, length of stay, total cost, and disability days. DATA EXTRACTION AND SYNTHESIS Data were independently extracted by 2 reviewers. The quality of the included studies was examined in accordance with the Cochrane guidelines and the Newcastle-Ottawa criteria. Data were pooled using a logistic fixed-effects model, and the subgroup pooled risk ratio with or without appendicolith was estimated. MAIN OUTCOMES AND MEASURES The primary outcome was the success rate of treatment. The hypothesis was formulated before data collection. RESULTS A total of 527 articles were screened. In 5 unique studies, 404 unique patients with uncomplicated appendicitis (aged 5-15 years) were enrolled. Nonoperative treatment was successful in 152 of 168 patients (90.5%), with a Mantel-Haenszel fixed-effects risk ratio of 8.92 (95% CI, 2.67-29.79; heterogeneity, P = .99; I2 = 0%). Subgroup analysis showed that the risk for treatment failure in patients with appendicolith increased, with a Mantel-Haenszel fixed-effects risk ratio of 10.43 (95% CI, 1.46-74.26; heterogeneity, P = .91; I2 = 0%). CONCLUSIONS AND RELEVANCE This meta-analysis shows that antibiotics as the initial treatment for pediatric patients with uncomplicated appendicitis may be feasible and effective without increasing the risk for complications. However, the failure rate, mainly caused by the presence of appendicolith, is higher than for appendectomy. Surgery is preferably suggested for uncomplicated appendicitis with appendicolith.
