RESUMEN
Objective: To investigate the effects of modified endoscopic retrograde appendicitis therapy (mERAT) on the treatment of children with different severities of acute appendicitis. Methods: This study was a case-control study. A total of 586 children with acute appendicitis, who were admitted to the Pediatric Department of Second Affiliated Hospital of Air Force Medical University between January 2019 and November 2023, were selected as the research subjects. According to the severity of the disease, the patients were divided into simple appendicitis group, suppurative appendicitis group and perforated appendicitis group. The baseline data, hospitalization treatment and costs, outcomes, and recurrence in each group were analyzed, and the difference in the effectiveness of mERAT between the groups were compared by Kruskal-Wallis H test and χ2 test. Results: Among 586 children, there were 338 males and 248 females. The age at onset was 7.0 (4.6, 9.4) years. There were 475 cases of simple appendicitis, 78 cases of suppurative appendicitis, and 33 cases of perforated appendicitis. There were no significant differences in age and gender among the three groups (F=0.59, χ2=3.31, both P>0.05). However, there were statistically significant differences in body temperature, white blood cell counts, neutrophil percentage, lymphocyte percentage, nausea or vomiting, right lower abdominal pain, umbilical pain, right lower abdominal tenderness, and right lower abdominal rebound pain (H=7.56, 161.52, 169.11, and 169.61, χ2=12.05, 13.82, 12.05, 7.74, 20.35, and 94.61, all P<0.05). Also, the treatment time, postoperative hospital stay, total hospital stay, and cost showed statistically significant differences (H=4.70, 33.66, 34.99, 30.37, all P<0.05). There was no significant difference in the initial treatment success rate (98.1% (466/475) vs. 98.7% (77/78) vs. 90.9% (30/33), P=0.057). During the 30 (23, 36) months of follow-up, the recurrence rate was 7.9% (35/433) in the simple appendicitis group, 20.8% (15/72) in the suppurative appendicitis group, and 30.0% (9/30) in the perforated appendicitis group, with a statistically significant difference (χ2=23.56, P<0.001). Among the children with recurrent appendicitis, 15 cases still chose mERAT, of them 11 cases (31.2%) had simple appendicitis, 2 cases (2/15) had suppurative appendicitis, and 2 cases (2/9) had perforated appendicitis.The latest time to recurrence in the 3 groups was 32, 35 and 10 months, respectively. Conclusion: Treatment with mERAT has a good effect in pediatric simple appendicitis, but has a higher recurrence rate despite a better initial treatment success rate in suppurative appendicitis and perforated appendicitis.

OBJECTIVE: Acute appendicitis is a wide spectrum disease, from simple inflammation to evident intestinal perforation. The correct interpretation of the degree of inflammation is crucial to guarantee appropriate treatment and adherence to protocols and guidelines. In order to investigate this concordance, the authors compared the definition of appendicitis and the predicted treatment among all surgeons affiliated to a single Pediatric Surgery School (consisting of 8 different centers). DESIGN: Twenty-two short recordings of intra-operative manipulation of appendices were shown to 56 surgeons, blindly to clinical information. Four items were collected and analyzed: classification of appendicitis, type and length of predicted antibiotic therapy, day of re-alimentation. Data were analyzed to identify the concordance kappa coefficient, stratified according to expertise of the responding surgeon. RESULTS: The 1232 evaluations obtained in all valued items low overall concordance. Subgroup analysis identified a good agreement between younger surgeons only in the choice of antibiotic (k 0.47). However, if the centers were divided between University and non-University Hospitals, a strong agreement was found in the former both for classification (k 0.45 vs 0.32) and type of antibiotic (k 0.42 vs 0.24). CONCLUSIONS: The overall concordance between surgeons in different centers in the diagnostic classification and predicted treatment of appendicitis is quite low. University Hospital have a highest concordance in both items at all levels of expertise; it might be postulated that teaching to younger surgeon increase the comparison between experts and finally the concordance and adherence to protocols within the center.

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.

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.

BACKGROUND: Nonoperative management of uncomplicated appendicitis is currently being promoted as treatment option, albeit 0.7-2.5% of appendectomies performed due to suspected acute appendicitis show histologically malignant findings. The purpose of this study was to investigate the incidence of neoplasm and malignancy of the appendix in patients presenting with suspected acute appendicitis in real world setting. METHODS: This is a retrospective single-centre investigation of 457 patients undergoing appendectomy between the years 2017-2020. The patients' demographics, symptoms and diagnosis, intraoperative findings, and histopathological results were analysed. RESULTS: In 3.7% (n = 17) histological analysis revealed neoplasms or malignancies. Median age was 48 years (20-90 years), without sex predominance. Leukocytes (11.3 ± 3.7 G/l) and C-reactive protein (54.2 ± 69.0 mg/l) were elevated. Histological analysis revealed low-grade mucinous appendiceal neoplasia (n = 3), sessile serrated adenoma of the appendix (n = 3), neuroendocrine tumours (n = 7), appendiceal adenocarcinoma of intestinal type (n = 3), and goblet cell carcinoma (n = 1). Additional treatment varied between no treatment or follow-up due to early tumour stage (n = 4), follow-up care (n = 3), additional surgical treatment (n = 8), or best supportive care (n = 2). CONCLUSIONS: Preoperative diagnosis of appendiceal tumours is difficult. Nonoperative management of patients with acute, uncomplicated appendicitis potentially prevents the correct diagnosis of malignant appendiceal pathologies. Therefore, close follow-up or surgical removal of the appendix is mandatory.

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.

Artificial intelligence is transforming healthcare. Artificial intelligence can improve patient care by analyzing large amounts of data to help make more informed decisions regarding treatments and enhance medical research through analyzing and interpreting data from clinical trials and research projects to identify subtle but meaningful trends beyond ordinary perception. Artificial intelligence refers to the simulation of human intelligence in computers, where systems of artificial intelligence can perform tasks that require human-like intelligence like speech recognition, visual perception, pattern-recognition, decision-making, and language processing. Artificial intelligence has several subdivisions, including machine learning, natural language processing, computer vision, and robotics. By automating specific routine tasks, artificial intelligence can improve healthcare efficiency. By leveraging machine learning algorithms, the systems of artificial intelligence can offer new opportunities for enhancing both the efficiency and effectiveness of surgical procedures, particularly regarding training of minimally invasive surgery. As artificial intelligence continues to advance, it is likely to play an increasingly significant role in the field of surgical learning. Physicians have assisted to a spreading role of artificial intelligence in the last decade. This involved different medical specialties such as ophthalmology, cardiology, urology, but also abdominal surgery. In addition to improvements in diagnosis, ascertainment of efficacy of treatment and autonomous actions, artificial intelligence has the potential to improve surgeons' ability to better decide if acute surgery is indicated or not. The role of artificial intelligence in the emergency departments has also been investigated. We considered one of the most common condition the emergency surgeons have to face, acute appendicitis, to assess the state of the art of artificial intelligence in this frequent acute disease. The role of artificial intelligence in diagnosis and treatment of acute appendicitis will be discussed in this narrative review.

BACKGROUND: The consequences of failed nonoperative management of appendicitis in older patients have not been described. METHODS: We used the 2004-2017 National Inpatient Sample to identify acute appendicitis patients managed nonoperatively (<65 years old: 32,469; ≥65 years old: 11,265). Outcomes included morbidity, length of stay (LOS), inpatient costs, and discharge to skilled facilities. Differences were estimated using propensity scores. RESULTS: For patients <65, nonoperative failure was associated with increased morbidity (7 â% [95 â% CI 6.9 â%-8.1 â%]), LOS (3 day [95 â% CI 3-4]), costs ($9015 [95 â% CI $8216- $9446]), and discharges to skilled facilities (1 â% [95 â% CI 0.9 â%-1.6 â%]) compared to successful nonoperative treatment. Patients ≥65 had differences in morbidity (14 â% [95 â% CI 13.6 â%-16.2 â%]), LOS (6 days [95 â% CI 5-6]), costs ($15,964 [95 â% CI $15,181- $17,708]), and discharges to skilled facilities (12 â% [95 â% CI: 10.0 â%-13.3]) compared to nonoperative success. CONCLUSIONS: Nonoperative management of appendicitis should be approached cautiously for older adults.

BACKGROUND: The purpose of this study was to (1) compare post-treatment outcomes of operative and nonoperative management of acute appendicitis in multi-morbid patients and (2) evaluate the generalizability of prior clinical trials by determining whether outcomes differ in multi-morbid patients compared to the young and healthy patients who resemble prior clinical trial participants. METHODS: We conducted a retrospective cohort study using the National Inpatient Sample from 2004 to 2017. We included 368,537 patients with acute, uncomplicated appendicitis who were classified as having 0 or 2+ comorbidities. We compared inpatient morbidity, mortality, length of stay, and costs using propensity scores. Unmeasured confounding was addressed with probabilistic sensitivity analysis. RESULTS: Overall, 5% of patients without comorbidities were treated nonoperatively versus 20% of multi-morbid patients. Compared to surgery, nonoperative management was associated with a 3.5% decrease in complications (95% confidence interval 3%-4%) for multi-morbid patients, but there was no significant difference for patients without comorbidity. However, nonoperative management was associated with a 1.5% increase in mortality for multimorbid patients (95% confidence interval 1.3%-1.7%). Costs and length of stay were lower for all patients treated with surgery. Probabilistic sensitivity analysis showed that results were robust to the effects of unmeasured confounding. CONCLUSION: Our results raise concerns about the generalizability of clinical trials that compared nonoperative and operative management of appendicitis because (1) those trials enrolled mostly young and healthy patients, and (2) results in multi-morbid patients differ from outcomes in younger and healthier patients.

BACKGROUND: Non-operative management (NOM) of simple appendicitis is becoming an increasingly researched treatment option. This systematic review aims to describe the short and long-term failure rates of NOM and the complication rate of appendicectomy in children with simple appendicitis. METHODS: The systematic review was registered a priori (CRD42022322149). Study inclusion criteria are: participants aged ≤ 18 years of age; groups undergoing both NOM and appendicectomy for simple appendicitis; outcomes including one or more of: NOM failure rate at 30 days or 1 year and beyond; study design: RCT or case control study. Four databases were searched and 3 reviewers determined study eligibility and data extraction. Risk of bias was assessed and meta-analysis was performed using Stata. RESULTS: The database search identified 2731 articles, 14 studies met the inclusion criteria; 4 RCTs and 10 case controlled studies. All studies had moderate-serious risk of bias. There were no deaths in either group in any study. Meta-analysis demonstrated a 30 day failure rate of 20 % (95 % CI 11-29 %) and 11 studies reported failure rate at 1 year or beyond at 32 % (95 % CI 25-38 %). Rates of significant complications of appendicectomy was 1 % (95 % CI 0-1 %). CONCLUSIONS: Non-operative management of simple appendicitis in children is safe, with moderate early success. The failure rate increases over time, resulting in eventual appendicectomy in a third of the children diagnosed with appendicitis. These data will enable clinicians to have an informed discussion with children and their parents about their treatment options for simple appendicitis. LEVEL OF EVIDENCE: II.

OBJECTIVE: Appendiceal neoplasms (ANs) are rare tumors that are often discovered incidentally during histopathological examinations. The increasing incidence of ANs is a critical issue in the non-operative management of acute appendicitis. This study aimed to document the temporal trends over a 12-year period by analyzing the clinical presentation, imaging findings, and histopathological features of ANs. SUBJECTS AND METHODS: Health records of patients who underwent appendectomy from 2011 to 2022 were examined. Demographic and clinical data, laboratory results, imaging findings, and histopathological features were documented. The characteristics of both ANs and non-neoplastic cases were evaluated. RESULTS: A total of 22,304 cases were identified, of which 330 (1.5%) were diagnosed with ANs. The odds ratio for ANs increased with age, with the highest odds ratio observed in patients aged 70 or older. Receiver Operating Characteristic analysis showed that age and appendiceal diameter were significant predictors of ANs. An optimal age cut-off point of 28.5 years was determined, yielding a sensitivity of 72% and a specificity of 64%. For appendiceal diameter, the optimal cut-off was found to be 9.5 mm, exhibiting a sensitivity of 77% and a specificity of 56%. CONCLUSION: Although the incidence of ANs remains relatively low, a steady increase has been observed over the past decade. The increasing rate of ANs raises concerns regarding non-surgical management options. The results of this study highlight the importance of considering ANs as a potential diagnosis in older patients and in patients with an appendix diameter greater than 9.5 mm. These findings may have implications for treatment and management.

Background: The pilephlebitis is the septic thrombophlebitis of the portal venous system ranging from asymptomatic to severe complications. Diagnosed based on imaging tests, and their treatment is based on antibiotics and anticoagulant therapy. Clinic case: 24 years male, appendectomy 12 days before. Readmission for 3 days with fever, jaundice and choluria; hyperbilirrubinemia. Intravenous contrast CT is performed, showed thrombus in portal, splenic and mesenteric vein system. Diagnosis of pylephlebitis is established, initiating managed with antibiotics and anticoagulant, with favorable clinical outcome. The pylephlebitis has an estimated incidence of 2.7 cases per year, with an unspecified clinical picture ranging from asymptomatic to severe cases with septic shock and hepatic failure. There may be accompanying fever and abdominal pain in more than 80% of the cases and presenting in some cases with leukocytosis and hyperbilirrubinemia. Intravenous contrast CT is the gold standard. The treatment is based on 4 points: Septic focus control, antibiotics, early anticoagulant and resolution of complications. Conclusions: The pylephlebitis should be taken into consideration as a possible secondary complication of intraabdominal infections. A timely diagnosis with a imaging tests and apply treatment reduce their morbidity and mortality.
Introducción: la pileflebitis es la tromboflebitis séptica del sistema venoso portal, que puede variar desde un cuadro asintomático hasta complicaciones severas. Su diagnóstico requiere estudios de imagen y su tratamiento se basa en la antibioticoterapia y anticoagulación. Caso clínico: paciente hombre de 24 años de edad, posoperado de apendicetomía 12 días previos. Reingresa por fiebre de tres días, ictericia y coluria, hiperbilirrubinemia. Se realiza tomografía con contraste intravenoso, evidenciando trombo en sistema portoesplemesaraico. Se establece diagnóstico de pileflebitis, iniciando manejo con antibióticos y anticoagulación, con evolución clínica favorable. La pileflebitis tiene una incidencia estimada de 2.7 casos por año, con un cuadro clínico inespecífico, que va desde un estado asintomático a casos graves con choque séptico y falla hepática. Puede haber dolor abdominal y fiebre en más del 80% de los casos, presentando en algunos casos leucocitosis e hiperbilirrubinemia. La tomografía con contraste intravenoso es el estudio de elección. El tratamiento se basa en cuatro puntos: control del foco séptico, antibióticos, anticoagulación precoz y resolución de las complicaciones. Conclusiones: se debe tener en cuenta a la pileflebitis como una posible complicación secundaria en casos de infecciones intraabdominales, estableciendo un diagnóstico oportuno con estudio de imagen y otorgar tratamiento temprano para reducir su morbimortalidad.

BACKGROUND: Routinely obtaining intraoperative cultures for abdominal infections is not a currently recommended evidence-based practice. Yet, cultures are frequently sent from these infections when they are managed by image-guided percutaneous drains. OBJECTIVE: This study aimed to determine the utility of cultures from percutaneously drained intra-abdominal abscesses. DESIGN: Retrospective medical record review. SETTING: Single university-affiliated institution. PATIENTS: Inpatients with an intra-abdominal abscess secondary to diverticulitis or appendicitis between 2013 and 2021 managed with image-guided percutaneous drain, excluding those with active chemotherapy, HIV, or solid organ transplant, were included in the study. MAIN OUTCOME MEASURES: Frequency culture data from percutaneous drains changed antimicrobial therapy. RESULTS: There were 221 patients who met the inclusion criteria. Of these, 56% were admitted for diverticulitis and 44% for appendicitis. Patients were 54% female and had a median age of 62 years (range, 18-93), and 14% were active smokers. The median length of hospitalization was 8 days (range, 1-78) and the median antibiotics course was 8 days (range, 1-22). Culture data from percutaneous drains altered antimicrobial therapy in 8% of patients (16/211). A culture was obtained from 95% of drains, with 78% of cultures with growth. Cultures grew multiple bacteria in 66% and mixed variety without speciation in 13%. The most common pathogen was the Bacteroides family at 33% of all bacteria. The most common empiric antibiotic regimens were ceftriaxone used in 33% of patients and metronidazole used in 40% of patients. Female sex ( p = 0.027) and presence of bacteria with any antibiotic resistance ( p < 0.01) were associated with higher likelihood of cultures influencing antimicrobial therapy. LIMITATIONS: Retrospective and single institution's microbiome. CONCLUSIONS: Microbiology data from image-guided percutaneous drains of abdominal abscesses altered antimicrobial therapy in 8% of patients, which is lower than reported in previously published literature on cultures obtained surgically. Given this low rate, similar to the recommendation regarding cultures obtained intraoperatively, routinely culturing material from drains placed in abdominal abscesses is not recommended.

LOS CULTIVOS DE ABSCESOS INTRA ABDOMINALES DRENADOS PERCUTNEAMENTE CAMBIAN EL TRATAMIENTO UNA REVISIN RETROSPECTIVA: ANTECEDENTES:La obtención rutinaria de cultivos intra-operatorios para infecciones abdominales no es una práctica basada en evidencia actualmente recomendada. Sin embargo, con frecuencia se envían cultivos de estas infecciones cuando se manejan con drenajes percutáneos guiados por imágenes.OBJETIVO:Determinar la utilidad de los cultivos de abscesos intra-abdominales drenados percutáneamente.DISEÑO:Revisión retrospectiva de gráficos.ESCENARIO:Institución única afiliada a la universidad.PACIENTES:Pacientes hospitalizados con absceso intra-abdominal secundario a diverticulitis o apendicitis entre 2013 y 2021 manejados con drenaje percutáneo guiado por imagen, excluyendo aquellos con quimioterapia activa, VIH o trasplante de órgano sólido.PRINCIPALES MEDIDAS DE RESULTADO:Los datos de cultivo de frecuencia de los drenajes percutáneos cambiaron la terapia antimicrobiana.RESULTADOS:Hubo 221 pacientes que cumplieron con los criterios de inclusión. De estos, el 56% ingresaron por diverticulitis y el 44% por apendicitis. El 54% de los pacientes eran mujeres, tenían una edad media de 62 años (18-93) y el 14% eran fumadores activos. La duración de hospitalización media fue de 8 días (rango, 1-78) y la mediana del curso de antibióticos fue de 8 días (rango, 1-22). Los datos de cultivo de drenajes percutáneos alteraron la terapia antimicrobiana en el 7% (16/221) de los pacientes. Se obtuvo cultivo del 95% de los drenajes, con un 79% de cultivos con crecimiento. Los cultivos produjeron múltiples bacterias en el 63% y variedad mixta sin especiación en el 13%. El patógeno más común fue la familia Bacteroides con un 33% de todas las bacterias. El régimen de antibiótico empírico más común fue ceftriaxona y metronidazol, utilizados en el 33% y el 40% de los pacientes, respectivamente. El sexo femenino ( p = 0,027) y la presencia de bacterias con alguna resistencia a los antibióticos ( p < 0,01) se asociaron con una mayor probabilidad de que los cultivos influyeran en la terapia antimicrobiana.LIMITACIONES:Microbioma retrospectivo y de una sola institución.CONCLUSIONES:Los datos microbiológicos de los drenajes percutáneos guiados por imágenes de los abscesos abdominales alteraron la terapia antimicrobiana en el 7% de los pacientes, que es inferior a la literatura publicada previamente sobre cultivos obtenidos quirúrgicamente. Dada esta baja tasa, similar a la recomendación sobre cultivos obtenidos intraoperatoriamente, no se recomienda el cultivo rutinario de material de drenajes colocados en abscesos abdominales.

BACKGROUND: Ultrasound is an accurate tool for diagnosing acute appendicitis. Conservative treatment for uncomplicated acute appendicitis is feasible and safe in children. However, no sonographic follow-up results from children with nonoperatively managed acute appendicitis have been reported. OBJECTIVE: To describe the sonographic appearance of the appendix at follow-up ultrasound and to attempt to identify signs predictive of recurrent acute appendicitis. MATERIALS AND METHODS: Children diagnosed with uncomplicated acute appendicitis and treated conservatively in our hospital from 2014 to 2019, and who presented for follow-up ultrasound at 3, 6 and 9 months, were included in our study. Clinical, laboratory and ultrasound data were recorded. RESULTS: By the end of follow-up, 29 (14.2%) of 204 children in the cohort had developed recurrent acute appendicitis and 175 had recovered uneventfully. On follow-up ultrasound, appendiceal diameter measured > 6 mm in 56/204 (27.5%) cases at 3 months and in 9/26 (34.5%) at 6 months. After 3 months, 102/204 (50%) children had normal appendiceal diameter on ultrasound. Appendiceal diameter > 6 mm was associated with intraluminal fluid or sludge in the appendiceal lumen at 3- and 6-month follow-up (P < 0.001, P = 0.002, respectively). Comparing cases with and without recurrence, at 3-month follow-up, appendiceal diameter > 6 mm was found in 17/29 (58.6%) cases vs. 39/175 (22.3%), respectively (P < 0.001). Appendiceal diameter returned to normal in 12/19 (63.2%) cases in the nonrecurrent acute appendicitis group compared with 2/7 (28.6%) in the recurrent acute appendicitis group (P = 0.05) at the 6-month follow-up. Intraluminal fluid or sludge was detected more frequently in the recurrent acute appendicitis versus the nonrecurrent acute appendicitis group at 3- (P < 0.001) and 6-month (P = 0.001) follow-up. CONCLUSION: Progressive normalization of appendiceal diameter was noted on follow-up ultrasound. The prevalence of both appendiceal diameter > 6 mm and intraluminal fluid or sludge were found to be increased in children who later developed recurrent acute appendicitis. Ultrasound appears to be a useful tool for follow-up in children with conservatively treated uncomplicated acute appendicitis and possibly might help predict recurrence.

Importance: The factors associated with the failure of nonoperative management of appendicitis and the differences in patient-reported outcomes between successful and unsuccessful nonoperative management remain unknown. Objectives: To investigate factors associated with the failure of nonoperative management of appendicitis and compare patient-reported outcomes between patients whose treatment succeeded and those whose treatment failed. Design, Setting, and Participants: This study was a planned subgroup secondary analysis conducted in 10 children's hospitals that included 370 children aged 7 to 17 years with uncomplicated appendicitis enrolled in a prospective, nonrandomized clinical trial between May 1, 2015, and October 31, 2018, with 1-year follow-up comparing nonoperative management with antibiotics vs surgery for uncomplicated appendicitis. Statistical analysis was performed from November 1, 2019, to February 12, 2022. Interventions: Nonoperative management with antibiotics vs surgery. Main Outcomes and Measures: Failure of nonoperative management and patient-reported outcomes. The relative risk (RR) of failure based on sociodemographic and clinical characteristics was calculated. Patient-reported outcomes were compared based on the success or failure of nonoperative management. Results: Of 370 patients (34.6% of 1068 total patients; 229 boys [61.9%]; median age, 12.3 years [IQR, 10.0-14.6 years]) enrolled in the nonoperative group, treatment failure occurred for 125 patients (33.8%) at 1 year, with 53 patients (14.3%) undergoing appendectomy during initial hospitalization and 72 patients (19.5%) experiencing delayed treatment failure after hospital discharge. Higher patient-reported pain at presentation was associated with increased risk of in-hospital treatment failure (RR, 2.1 [95% CI, 1.0-4.4]) but not delayed treatment failure (RR, 1.3 [95% CI, 0.7-2.3]) or overall treatment failure at 1 year (RR, 1.5 [95% CI, 1.0-2.2]). Pain duration greater than 24 hours was associated with decreased risk of delayed treatment failure (RR, 0.3 [95% CI, 0.1-1.0]) but not in-hospital treatment failure (RR, 1.2 [95% CI, 0.5-2.7]) or treatment failure at 1 year (RR, 0.7 [95% CI, 0.4-1.2]). There was no increased risk of treatment failure associated with age, white blood cell count, sex, race, ethnicity, primary language, insurance status, transfer status, symptoms at presentation, or imaging results. Health care satisfaction at 30 days and patient-reported, health-related quality of life at 30 days and 1 year were not different. Satisfaction with the decision was higher with successful nonoperative management at 30 days (28.0 vs 27.0; difference, 1.0 [95% CI, 0.01-2.0]) and 1 year (28.1 vs 27.0; difference, 1.1 [95% CI, 0.2-2.0]). Conclusions and Relevance: This analysis suggests that a higher pain level at presentation was associated with a higher risk of initial failure of nonoperative management and that a longer duration of pain was associated with lower risk of delayed treatment failure. Although satisfaction was high in both groups, satisfaction with the treatment decision was higher among patients with successful nonoperative management at 1 year.
