Abstract
PURPOSE Emergency surgery (ES) for complicated appendicitis (CA) is associated with high morbidity. Interval appendectomy (IA) decreases this rate; however, nonoperative management (NOM) is not always successful. Some patients require unplanned ES due to NOM failure (IA failure: IA-F). This study aimed to verify the benefits of IA and to evaluate the risk factors for NOM failure. METHODS Patients diagnosed with CA who underwent surgery between January 2012 and December 2021 were included in this study. We compared the surgical outcomes of the ES group with those of the IA success (IA-S) and IA-F groups. We also analyzed 14 factors that predicted NOM failure. RESULTS Among 302 patients, the rate of severe complications (Clavien-Dindo grade ≥ III) was significantly higher in the ES group (N = 165) than in the IA-S group (N = 102). The rates were equal between the ES (N = 165) and IA-F (N = 35) groups. NOM was successful in 110 patients and failed in 27. Lack of abscesses, comorbidities, high WBC count, and free air were independent risk factors for NOM failure. CONCLUSIONS Considering the benefits of IA and the non-inferior surgical outcomes of IA-F compared to ES, IA is a good therapeutic strategy for CA. However, in patients exhibiting four independent risk factors for NOM failure, careful monitoring of unplanned ES is necessary.

Abstract
Appendicitis is one of the most common abdominal emergencies. Evidence is controversial in determining if the in-hospital time delay to surgery can worsen the clinical presentation of appendicitis. This study aimed to clarify if in-hospital surgical delay significantly affected the proportion of complicated appendicitis in a large prospective cohort of patients treated with appendectomy for acute appendicitis. Patients were grouped into low, medium, and high preoperative risk for acute appendicitis based on the Alvarado scoring system. Appendicitis was defined as complicated in cases of perforation, abscess, or diffuse peritonitis. The primary outcome was correlation of in-hospital delay with the proportion of complicated appendicitis. The study includes 804 patients: 278 (30.4%) had complicated appendicitis and median time delay to surgery in low-, medium-, and high-risk group was 23.15 h (13.51-31.48), 18.47 h (10.44-29.42), and 13.04 (8.13-24.10) h, respectively. In-hospital delay was not associated with the severity of appendicitis or with the presence of postoperative complications. It appears reasonably safe to delay appendicectomy for acute appendicitis up to 24 h from hospital admission. Duration of symptoms was a predictor of complicated appendicitis and morbidity. Timing for appendicectomy in acute appendicitis should be calculated from symptoms onset rather than hospital presentation.

Abstract
RATIONALE AND OBJECTIVES This study aimed to develop and validate a deep learning and radiomics combined model for differentiating complicated from uncomplicated acute appendicitis (AA). MATERIALS AND METHODS This retrospective multicenter study included 1165 adult AA patients (training cohort, 700 patients; validation cohort, 465 patients) with available abdominal pelvic computed tomography (CT) images. The reference standard for complicated/uncomplicated AA was the surgery and pathology records. We developed our combined model with CatBoost based on the selected clinical characteristics, CT visual features, deep learning features, and radiomics features. We externally validated our combined model and compared its performance with that of the conventional combined model, the deep learning radiomics (DLR) model, and the radiologist's visual diagnosis using receiver operating characteristic (ROC) curve analysis. RESULTS In the training cohort, the area under the ROC curve (AUC) of our combined model in distinguishing complicated from uncomplicated AA was 0.816 (95% confidence interval [CI]: 0.785-0.844). In the validation cohort, our combined model showed robust performance across the data from three centers, with AUCs of 0.836 (95% CI: 0.785-0.879), 0.793 (95% CI: 0.695-0.872), and 0.723 (95% CI: 0.632-0.802). In the total validation cohort, our combined model (AUC = 0.799) performed better than the conventional combined model, DLR model, and radiologist's visual diagnosis (AUC = 0.723, 0.755, and 0.679, respectively; all P < 0.05). Decision curve analysis showed that our combined model provided greater net benefit in predicting complicated AA than the other three models. CONCLUSION Our combined model allows the accurate differentiation of complicated and uncomplicated AA.

Abstract
BACKGROUND Despite widespread initiatives to reduce ionizing radiation for appendicitis diagnosis, computed tomography (CT) scanning postoperatively remains common. The Pediatric Surgery Quality Collaborative (PSQC) aimed to identify differences between children's hospitals with high and low postoperative CT usage for complicated appendicitis. METHODS Using National Surgery Quality Improvement Program Pediatric data from PSQC children's hospitals, we compared postoperative CT imaging for complicated appendicitis (April 2020-March 2021). Key stakeholders from 11 hospitals (5 low CT utilization, 6 high CT utilization) participated in semi-structured interviews regarding postoperative imaging. Qualitative analysis of transcripts was performed deductively and inductively based on the Theoretical Domains Framework (TDF). RESULTS Five of twelve TDF domains were most prominent in influencing CT use: skills, beliefs about capabilities, intentions/goals, memory and decision processes, and environment. Children's hospitals with lower rates of postoperative CT use tended to: trust and educate the ultrasound technicians; believe US strengths outweigh weaknesses; image no sooner than 7 days postoperatively; have access to sufficient quality improvement resources; maintain trusting relationships between specialties; and prioritize radiation stewardship. CONCLUSION Hospitals at extremes of postoperative CT use for complicated appendicitis reveal strategies for improvement, which include imaging protocol development and adherence, quality improvement resource availability, interdisciplinary collaboration, and promoting radiation stewardship.

Abstract
BACKGROUND /Purpose: Acute appendicitis (AA) stands as the most prevalent cause of acute abdominal pain among children. The potential for morbidity escalates significantly when uncomplicated appendicitis (UA) progresses to complicated appendicitis (CA), which can encompass gangrenous, necrotic, or perforated appendicitis. Consequently, establishing an early and accurate diagnosis of AA, and effectively differentiating CA from UA, becomes paramount. This study explores the diagnostic utility of various blood biomarkers for distinguishing CA from UA in pediatric patients. METHODS We conducted a retrospective review of medical records pertaining to pediatric patients who underwent surgery for AA. Patients were categorized as either having UA or CA based on histopathological examination of the appendix. The data collected and analyzed included demographic information, white blood cell (WBC) count, neutrophil proportion, lymphocyte proportion, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP) levels upon admission. RESULTS Among the 192 pediatric patients who underwent surgery for AA, 150 were diagnosed with UA, while 42 were diagnosed with CA. The CA group exhibited significantly higher neutrophil proportions, NLRs, PLRs, and CRP levels, alongside lower lymphocyte proportions (all p < 0.01) compared to the UA group. Receiver operating characteristic (ROC) curve analysis disclosed that CRP exhibited the highest specificity, sensitivity, and positive and negative predictive values for predicting CA. CONCLUSION CRP emerges as a valuable biomarker for differentiating complicated appendicitis from uncomplicated appendicitis.

Abstract
PURPOSE Transumbilical laparoscopic-assisted surgery (TULS) mixed benefits of laparoscopic and open surgeries. Transumbilical laparoscopic-assisted appendectomy (TULAA) is a well-known procedure, accepted and currently used by pediatric surgeons for treatment of uncomplicated appendicitis (UA). There is no current agreement in its use for the complicated appendiceal infections (CA). We reported our results using TULAA for both UA and CA. METHODS We retrospectively collected TULAA performed between April 2017 and April 2022. Appendicitis were classified in UA and CA. We analyzed conversion rate, operative time, length of stay, surgical site infections (SSIs) rate, postoperative intra-abdominal abscess and costs. RESULTS Over 5 years, 316 children underwent TULAA. Conversion rate was 3%. Mean age at surgery was 9.36 years (IQR 2-16). Forty-nine appendicitis were CA. Operative time and hospital stay was higher in CA than in UA group (38.33 vs. 60.73 min, p < 0.00001; 4 vs. 7 days, p < 0.00001). SSIs rate showed no statistically significant difference between two groups. Incidence of postoperative intra-abdominal collections was 11% in CA and 1% in UA. TULAA's cost was 192.07 €. CONCLUSION In our series, TULAA seems to be safe, feasible and cost-effective for both uncomplicated and complicated appendicitis, with no disadvantage in terms of outcomes compared to what is reported in literature for CLS.

Abstract
Acute appendicitis is a common surgical emergency. Complicated appendicitis usually warrants perioperative antibiotic treatment in order to prevent infectious complications. Whether routine microbiological testing benefits the individual patient is a topic of debate. The goal of our study was to assess perioperative antibiotic prescriptions as well as the benefit of microbiological testing during the appendectomy as a predictor for bacteria encountered in infectious complications. This is a retrospective analysis of 1218 consecutive patients that underwent appendectomy at a tertiary referral center between 2014 and 2021. The patient charts were systematically analyzed regarding intraoperative outcome, microbiologic results, and postoperative infectious complications. 1218 patients were included in this study of which 768 were uncomplicated appendicitis (UA) and 450 were complicated appendicitis (CA). Microbiological testing was performed in 39.2% of UA cases (33.6% of which grew bacteria) compared to 74.9% of CA cases (78.6% positive cultures). The strongest individual predictors for SSI were gangrenous and perforated appendicitis. A total of 58 surgical-site infections developed, of which 49 were intra-abdominal fluid collections or abscesses. Thirty-two patients had revision surgery or CT-guided drainage for SSI. In the cases where microbiological testing was done both during the appendectomy and the SSI, 13/18 showed different bacteria on culture testing. The infectious outcome was favorable in 98.3%. While microbiological testing offers insights into resistance patterns, it is of little benefit for the individual patient, given the low predictive value for bacteria found during SSI. Achieving source control combined with empiric antibiotic coverage leads to favorable outcomes independent of culture results.

OBJECTIVES To validate the Atema and APSI scoring systems in the diagnosis of complicated vs uncomplicated appendicitis. To compare these scoring systems with computed tomography (CT) imaging alone to establish which method provides most accurate prediction of complicated vs uncomplicated appendicitis. METHODS This was a retrospective review of a sample of 160 patients that underwent appendicectomy and CT imaging for suspected appendicitis between 2018 and 2021 in a tertiary university teaching hospital. Each scoring system was applied to all patients and results analysed and compared with the effectiveness of CT imaging, RESULTS: 32.5% (n = 52) were found to have complicated appendicitis and 67.5% (n = 108) uncomplicated appendicitis. Application of the Atema score to our cohort of patients resulted in a sensitivity 76.9% [CI (64.2, 87.5), specificity 58.7% [CI (48.9, 68.1)], PPV 47.1% [CI (40.5, 53.8) and NPV 84.2% [CI (76.0, 89.9)]. By comparison, the APSI yielded a sensitivity 50.9% [CI (36.6, 65.4)], specificity 76.1% [CI (67.0, 87.8)], PPV 50% [CI (39.2, 60.6)] and NPV 76% [CI (71.1, 81.7)]. Radiology prediction of complicated vs uncomplicated appendicitis with CT imaging showed sensitivity 46% [CI (32.2, 60.5)], specificity 79%; [CI (69.8, 86)], PPV 51% [CI (39.6, 62.5)] and NPV 75% [CI (69.8, 79.9)]. CONCLUSION By comparing the APSI and Atema et al. scoring systems with CT reporting in our hospital, it appears that the Atema may confer some benefit in stratifying patient risk of complicated versus uncomplicated appendicitis. Further larger scale prospective studies are required.

Abstract
Background It is controversial which treatment method is superior in plastron appendicitis and the research is still going on. The aim of this study is to compare treatment methods for plastron appendicitis in the adult population with our experience. Materials and Methods The data of 92 patients who were diagnosed with plastron appendicitis in university hospital between 2015 and 2021 were analyzed retrospectively. Data were taken from the hospital database. The patients were divided into three groups: those treated with primary surgery, with interval appendectomy and only with conservative method. Results Interval appendectomy resulted in a lower rate of conversion to open surgery compared to primary surgery, shorter operative time, and lower complication rates. Surgical procedures were found to be superior in detecting neoplasms compared to conservative treatment. After conservative treatment, one of three patients was retreated with the diagnosis of acute appendicitis. Conclusion In plastron appendicitis, routine interval appendectomy can be performed due to its advantages over other treatments such as the frequency of attacks after conservative treatment, the risk of the tumor being overlooked in conservative treatment, and the high rate of complications and conversion to open surgery in the primary surgery group.

Abstract
OBJECTIVE To investigate the risk factors and the value of clinical prediction model for complicated appendicitis (CA) during pregnancy. METHODS Prospective analysis of pregnant patients who underwent appendectomy at a single tertiary care center between February 2020 and February 2023 and who ultimately had pathologically confirmed acute appendicitis (AA). According to intraoperative conditions and postoperative pathology, they were divided into the CA group and the uncomplicated appendicitis (UA) group. The two groups of patients were then compared in terms of demographic characteristics, disease features, ancillary tests and predictive models of acute appendicitis. RESULTS A total of 90 patients with AA in pregnancy were included, 21 of whom had CA in pregnancy and 69 had UA in pregnancy. Multivariate regression analysis showed that gestational week, neutrophil ratio and C-reactive protein (CRP) were independent risk factors for CA during pregnancy. Relative to the first trimester, the third trimesters had an increased risk of complicated appendicitis (OR = 12.48, 95% CI: 1.56-99.57, P = 0.017). Neutrophil ratio ≥85.30% (OR = 24.54, 95% CI: 2.59-232.72, P = 0.005) and CRP ≥34.26 mg/L (OR = 7.86, 95% CI: 2.18-28.38, P = 0.002) had a significantly increased risk of CA. The AIR and AAS score models were statistically different between the two groups, but with a lower sensitivity of 52.38% and 42.86%, respectively. CONCLUSION The third trimesters, neutrophil ratio ≥85.30% and CRP ≥34.26 mg/L may be key predictors of CA in pregnancy. The current scoring model is inadequate to identify complex appendicitis in pregnancy and further research is needed.

Abstract
INTRODUCTION Bacteria play an important role not only in pathogenesis of appendicitis but also in the postoperative course of patients. However, the usefulness of an intraoperative swab during appendectomy is controversial. The primary aim of this study was to investigate the impact of intraoperative swab during appendectomy on the postoperative outcome in patients with uncomplicated and complicated appendicitis. METHODS A retrospective analysis was conducted on a consecutive series of 1570 adult patients who underwent appendectomy for acute appendicitis at the University Hospital Erlangen between 2010 and 2020. Data regarding the intraoperative swab were collected and analyzed for the entire cohort as well as for patients with uncomplicated and complicated appendicitis. RESULTS An intraoperative swab was taken in 29% of the cohort. The bacterial isolation rate in the obtained intraoperative swabs was 51%, with a significantly higher rate observed in patients with complicated appendicitis compared to those with uncomplicated appendicitis (79% vs. 35%, p < 0.001). The presence of a positive swab was significantly associated with worse postoperative outcomes, including higher morbidity, increased need for re-surgery, and longer hospital stay, when compared to patients without a swab or with a negative swab. A positive swab was an independent risk factor for postoperative morbidity (OR 9.9 (95% CI 1.2-81.9), p = 0.034) and the need for adjustment of postoperative antibiotic therapy (OR 8.8 (95% CI 1.1-72.5), p = 0.043). However, a positive swab resulted in postoperative antibiotic therapy adjustment in only 8% of the patients with bacterial isolation in the swab. CONCLUSION The analysis of swab samples obtained during appendectomy for acute appendicitis can help identify patients at a higher risk of a worse postoperative outcome. However, the frequency of antibiotic regime changes based on the swab analysis is low.

Abstract
BACKGROUND Appendicitis is one of the most common pediatric surgical procedures in the United States. However, wide variation remains in antibiotic prescribing and pain management across and within institutions. We aimed to minimize variation in antibiotic usage and decrease opioid prescribing at discharge for children with complicated appendicitis by implementation of a quality improvement (QI) initiative. METHODS On December 1st, 2021, a QI initiative standardizing postoperative care for complicated appendicitis was implemented across a tertiary pediatric healthcare system with two main surgical centers. QI initiative focused on antibiotic and pain management. An extensive literature search was performed and a total of 20 articles matching our patient population were critically appraised to determine the best evidence-based interventions to implement. Antibiotic regimen included: IV or PO ceftriaxone/metronidazole immediately post-operatively and transition to PO amoxicillin-clavulanic acid for completion of 7-day total course at discharge. Discharge pain control regimen included acetaminophen, ibuprofen, as needed gabapentin, and no opioid prescription. Guideline compliance were closely monitored for the first six months following implementation. RESULTS In the first 6-months post-implementation, compliance with use of ceftriaxone/metronidazole as initial post-operative antibiotics was 75.6 %. Transition to PO amoxicillin-clavulanic acid prior to discharge increased from 13.7 % pre-implementation to 73.7 % 6-months post-implementation (p < 0.001). Compliance with a 7-day course of antibiotics within the first 6-months post-implementation was 60 % across both sites. After QI intervention, overall opioid prescribing remained at 0 % at one surgical site and decreased from 17.6 % to 0 % at the second surgical site over the study timeframe (p < 0.001). CONCLUSION Antibiotic use can be standardized and opioid prescribing minimized in children with complicated appendicitis using QI principles. Continued monitoring of the complicated appendicitis guideline is needed to assess for further progress in the standardization of post-operative care. STUDY TYPE Quality improvement. LEVEL OF EVIDENCE Level III.

Abstract
Appendicitis in infants is a life-threatening condition that is seldom studied. Our purpose was to conduct a comprehensive evaluation of appendicitis in this age group. This was a multicenter retrospective study. Patients aged under one year with surgically confirmed appendicitis during January, 2010 to May, 2022 were identified from four institutional databases. The patients were grouped as neonates or older infants based on their age at the onset of symptoms associated with acute appendicitis. The study encompassed 98 infants, with median age of 66.5 (IQR, 13.8-176.0) days. Neonates were more likely to exhibit abdominal distension (64.9%) and fever (56.8%), while older infants more frequently presented with fever (88.5%) and vomiting (49.2%). Most patients (76.5%) were misdiagnosed during their initial clinical encounter, with a -rate was 3.1% (3 deaths), with neonates exhibiting a rate of 5.4%, and older infants 1.6%. Compared to older infants, neonates showed a higher incidence of appendiceal perforation (OR, 2.9; 95%CI, 1.1-8.1), mechanical ventilation (OR, 9.5; 95%CI, 3.1-29.2), and ICU admission (OR, 16.1; 95%CI, 5.6-45.7). However, there were no significant differences in mortality rates, 30-day readmission rates, and surgical complications between the two groups. CONCLUSION Although most infants with appendicitis were misdiagnosed during the first clinical encounter, the observed mortality rates were considerably lower than previously reported. While neonates and infants over 28 days displayed differing clinical presentations and disease severity, their outcomes were similar. WHAT IS KNOWN • Appendicitis in infants is a critical yet underemphasized health concern, often misdiagnosed at initial clinical encounters due to its atypical presentation and non-specific symptoms. • The mortality rates in the neonates with appendicitis was 23% during the past decades. WHAT IS NEW • The neonates and older infants displayed differing clinical presentations and disease severity. The treatment outcomes were similar. • The mortality rate for infantile appendicitis (3.1%) was significantly lower than historically reported.

Abstract
BACKGROUND Early and accurate preoperative diagnosis of complicated appendicitis mandates the identification of new markers. The aim of this study is to determine whether preoperative serum sodium levels are useful for predicting the severity of acute appendicitis. METHODS We retrospectively analyzed 475 patients who underwent emergency appendectomies between January 2018 and February 2023 in a general hospital in Brazil. The patients were divided into 2 groups: complicated (n = 254) and uncomplicated (n = 221). Hyponatremia was defined as serum sodium levels < 136 mEq/L. The primary outcome was to evaluate if hyponatremia is associated with complicated appendicitis. RESULTS The patients had a median age of 22 years, and the median serum sodium level was 137 mEq/L in patients with complicated appendicitis and 139 mEq/L in uncomplicated appendicitis (P < 0.001). The analysis of the receiver operating characteristic curve used as the best cutoff value of serum sodium of 136 mEq/L with a sensitivity of 45.7%, specificity of 86.4%, positive predictive value of 79.5%, and negative predictive value of 58.1% for the diagnosis of complicated AA. Of the 254 patients with complicated appendicitis, 84 (33.1%) had serum sodium levels below 136 mEq/L, while only 12 (5.4%) patients with uncomplicated appendicitis had values below this cutoff. Patients with hyponatremia were 5 times more likely to develop complicated appendicitis. (odds ratio: 5.35; 95% confidence interval: 3.39-8.45) CONCLUSIONS: Preoperative serum sodium levels are a useful tool for predicting the severity of acute appendicitis. Due to its low cost and wide availability, it has become an extremely relevant marker.

Abstract
BACKGROUND Acute appendicitis (AA) is one of the most common surgical emergencies worldwide. It's classified into simple or complicated disease. Due to the high prevalence of the disease, AA has been studied as a marker to assess the quality of care afforded to minority groups. The purpose of this study was to compare AA outcomes in foreign workers (FW) to the general population in northern Israel. METHODS This is a retrospective cohort study. We identified all patients aged 18-50 who were admitted to our institution between January 1st, 2013 and October 31st, 2018, with the diagnosis of acute appendicitis. The study group included all FW and the control group included citizens of Israel. Study patients were matched based on age, sex, and co-morbidities. We compared time to presentation, admission parameters and disease outcomes. Our study outcomes were disease severity and length of hospital stay. RESULTS We identified 20 FW and 97 matched local patients. FW presented with significantly higher heart rate, temperature, and white blood cell count (WBC). Duration of symptoms was comparable between the two groups. The rates of complicated disease were significantly higher among FW (45 vs 17.5%, p < 0.0001). Length of hospitalization was significantly longer in the FW group (4.8 vs. 3.9 days, p = 0.01). The odds ratio of FWs for having a complicated disease was OR = 3.85 [95% CI: 1.38, 10.72], p = 0.01. Multivariate analysis identified FW and duration of symptoms as significantly contributing to a complicated disease outcome. CONCLUSIONS Although duration of symptoms was comparable to the local population, FW in northern Israel are at increased risk for a complicated disease which resulted in longer hospital stay. Further studies may enlighten the reason for this disparity.

Abstract
PURPOSE Appendicitis is among the most common acute conditions treated by general surgery. While uncomplicated appendicitis (UA) can be treated delayed or even non-operatively, complicated appendicitis (CA) is a serious condition with possible long-term morbidity that should be managed with urgent appendectomy. Distinguishing both conditions is usually done with computed tomography. The goal of this study was to develop a model to reliably predict CA with widespread available clinical and laboratory parameters and without the use of sectional imaging. METHODS Data from 1132 consecutive patients treated for appendicitis between 2014 and 2021 at a tertiary care hospital were used for analyses. Based on year of treatment, the data was divided into training (n = 696) and validation (n = 436) samples. Using the development sample, candidate predictors for CA-patient age, gender, body mass index (BMI), American Society of Anesthesiologist (ASA) score, duration of symptoms, white blood count (WBC), total bilirubin and C-reactive protein (CRP) on admission and free fluid on ultrasound-were first investigated using univariate logistic regression models and then included in a multivariate model. The final development model was tested on the validation sample. RESULTS In the univariate analysis age, BMI, ASA score, symptom duration, WBC, bilirubin, CRP, and free fluid each were statistically significant predictors of CA (each p < 0.001) while gender was not (p = 0.199). In the multivariate analysis BMI and bilirubin were not predictive and therefore not included in the final development model which was built from 696 patients. The final development model was significant (x2 = 304.075, p < 0.001) with a sensitivity of 61.7% and a specificity of 92.1%. The positive predictive value (PPV) was 80.4% with a negative predictive value (NPV) of 82.0%. The receiver operator characteristic of the final model had an area under the curve of 0.861 (95% confidence interval 0.830-0.891, p < 0.001. We simplified this model to create the NoCtApp score. Patients with a point value of ≤ 2 had a NPV 95.8% for correctly ruling out CA. CONCLUSIONS Correctly identifying CA is helpful for optimizing patient treatment when they are diagnosed with appendicitis. Our logistic regression model can aid in correctly distinguishing UA and CA even without utilizing computed tomography.

Abstract
Objective To develop a logistic regression model that combines clinical and radiological parameters for prediction of complicated appendicitis. Methods 248 patients with histologically proven uncomplicated (n = 214) and complicated (n = 34) acute appendicitis were analyzed retrospectively. All patients had undergone a presurgical abdominal and/or pelvic computed tomography (CT) scan, assessed by two radiologists. A model using univariate and multivariate logistic regression analyses was developed, and the strength of association between independent predictors and complicated acute appendicitis was evaluated by adjusted odds radio. Clinical parameters were gender, age, anorexia, vomiting, duration of symptoms, right lower abdominal quadrant (RLQ) tenderness, rebound tenderness, body temperature, white blood cell (WBC) count, and neutrophil ratio. Radiological parameters were appendix diameter, appendicolith, caecal wall thickening, mesenteric lymphadenopathy, extraluminal air, abscess, fat stranding, and periappendicular fluid. Results Four features (body temperature>37.2 °C, vomiting, appendicolith, and periappendiceal fluid) were included in the logistic regression model, and yielded an area under the curve (AUC) of 0.87 (95% confidence interval (CI), 0.80-0.93), sensitive of 88%, and specificity of 74%. Conclusion The logistic regression model makes an accurate and simple prediction of complicated appendicitis possible.

Abstract
BACKGROUND Complicated appendicitis during pregnancy directly affects the clinical prognosis of both mother and fetus. However, accurate identification of complicated appendicitis in pregnancy is fraught with various challenges. The purpose of this study was to identify the risk factors and to develop a useful nomogram to predict complicated appendicitis during pregnancy. METHODS This retrospective study involved pregnant women who underwent appendectomy at the Maternal and Child Health Hospital of Hubei Provincial from May 2016 to May 2022 and who ultimately had histopathological confirmed acute appendicitis. Univariate and multivariate logistic regression were applied to analyze clinical parameters and imaging features as a way to identify risk factors. Then, nomogram and scoring systems predicting complicated appendicitis in pregnancy were constructed and evaluated. Finally, the potential non-linear association between risk factors and complicated appendicitis was analyzed using restricted cubic splines. RESULTS Three indicators were finally identified for the construction of the nomogram: gestational weeks, C-reactive protein (CRP), and neutrophil percentage (NEUT%). To improve the clinical utility, the gestational weeks were divided into three periods (first trimesters, second trimesters, and third trimesters), while the optimal cut-offs for CRP level and NEUT% were found to be 34.82 mg/L and 85.35%, respectively. Multivariate regression analysis showed that third trimesters (P = 0.013, OR = 16.81), CRP level ≥ 34.82 mg/L (P = 0.007, OR = 6.24) and NEUT% ≥85.35% (P = 0.011, OR = 18.05) were independent risk factors for complicated appendicitis. The area under the ROC curve (AUC) of the nomogram predicting complicated appendicitis in pregnancy was 0.872 (95% CI: 0.803-0.942). In addition, the model was shown to have excellent predictive performance by plotting calibration plots, Decision Curve Analysis (DCA), and clinical impact curves. When the optimal cut-off point of the scoring system was set at 12, the corresponding AUC, sensitivity, specificity, Positive Likelihood Ratio (PLR), Negative Likelihood Ratio (NLR), Positive Predictive Value (PPV), and Negative Predictive Value (NPV) values were AUC: 0.869(95% CI: 0.799-0.939),100%, 58.60%, 2.41, 0, 42%, and 100%, respectively. The restricted cubic splines revealed a linear relationship between these predictors and complicated appendicitis during pregnancy. CONCLUSIONS The nomogram utilizes a minimum number of variables to develop an optimal predictive model. Using this model, the risk of developing complicated appendicitis in individual patients can be determined so that reasonable treatment choices can be made.

Abstract
PURPOSE The treatment strategies for acute appendicitis differ depending on the facility, and various studies have investigated the usefulness of conservative treatment with antibiotics, laparoscopic surgery, and interval appendectomy (IA). However, although laparoscopic surgery is widely used, the clinical strategy for acute appendicitis, especially complicated cases, remains controversial. We assessed a laparoscopic surgery-based treatment strategy for all patients diagnosed with appendicitis, including those with complicated appendicitis (CA). METHODS We retrospectively analysed patients with acute appendicitis treated in our institution between January 2013 and December 2021. Patients were classified into uncomplicated appendicitis (UA) and CA groups based on computed tomography (CT) findings on the first visit, and the treatment course was subsequently compared. RESULTS Of 305 participants, 218 were diagnosed with UA and 87 with CA, with surgery performed in 159 cases. Laparoscopic surgery was attempted in 153 cases and had a completion rate of 94.8% (145/153). All open laparotomy transition cases (n = 8) were emergency CA surgery cases. No significant differences were found in the incidence of postoperative complications in successful emergency laparoscopic surgeries. In univariate and multivariate analyses for the conversion to open laparotomy in CA, only the number of days from onset to surgery ≥ 6 days was an independent risk factor (odds ratio: 11.80; P < 0.01). CONCLUSION Laparoscopic surgery is preferred in all appendicitis cases, including CA. Since laparoscopic surgery is difficult for CA when several days from the onset have passed, it is necessary that surgeons make an early decision on whether to operate.

Abstract
INTRODUCTION Complicated appendicitis (CA) is often indicated for emergency surgery; however, preoperative predictors of pathological CA (pCA) remain unclear. Furthermore, characteristics of CA that can be treated conservatively have not yet been established. METHODS 305 consecutive patients diagnosed with acute appendicitis were reviewed. The patients were divided into two groups: an emergency surgery and a conservative treatment group. The emergency surgery group was pathologically classified as having uncomplicated appendicitis (pUA) and pCA, and the preoperative predictors of pCA were retrospectively assessed. Based on the preoperative pCA predictors, a predictive nomogram whether conservative treatment would be successful or not was created. The predictors were applied to the conservative treatment group, and the outcomes were investigated. RESULTS In the multiple logistic regression analysis of the factors contributing to pCA, C-reactive protein ≥3.5 mg/dL, ascites, appendiceal wall defect, and periappendiceal fluid collection were independent risk factors. Over 90% of cases without any of the above four preoperative pCA predictors were pUA. The accuracy of the nomogram was 0.938. CONCLUSION Our preoperative predictors and nomogram are useful to aid in distinguishing pCA and pUA and to predict whether or not conservative treatment will be successful. Some CA can be treated with conservative treatment.

Abstract
Background Acute appendicitis is one of the most common surgical emergencies worldwide. Preoperative assessment of the risk of complicated appendicitis may aid in treatment planning. We sought to investigate the association between pre-appendectomy hyponatremia and diagnosis of complicated appendicitis. Methods The TriNetX platform, a federated health research network that aggregates de-identified electronic health record data of over 90 million patients across the United States, was queried for patients who underwent appendectomy starting January 2019 and who had at least one sodium value from the preoperative period. The study population was stratified into three age groups: pediatric (age < 18), adult (age 18-64), and older adult (age ≥ 65). These groups were subdivided into patients with preoperative hyponatremia (<135 mmol/L) and normonatremia (135-145 mmol/L). Results Among the 61,245 patients who met inclusion criteria, 17,546 were included for analysis following propensity score matching. The odds of complicated appendicitis were highest in pediatric patients (age < 18) with pre-appendectomy hyponatremia (odds ratio [OR] = 2.91, 95 % CI [2.53, 3.35]). Patients age 18-64 and aged ≥ 65 with preoperative hyponatremia also demonstrated increased odds of a complicated appendicitis diagnosis, but to a lesser extent (OR = 2.11, 95 % CI [1.92, 2.32] (OR = 1.49, 95 % CI [1.25, 1.77], respectively). Conclusions In a large analysis of matched patients with acute appendicitis, we found an association between immediate preoperative hyponatremia and complicated appendicitis. Future studies are indicated to further evaluate the role of hyponatremia as a potential diagnostic marker for complicated appendicitis in all age groups. Key message This study suggests a role of hyponatremia as one of multiple variables to incorporate into future clinical decision tools for complicated acute appendicitis.

Abstract
Children undergoing appendicectomy for complicated appendicitis are at an increased risk of post-operative morbidity. Placement of an intra-peritoneal drain to prevent post-operative complications is controversial. We aimed to assess the efficacy of prophylactic drain placement to prevent complications in children with complicated appendicitis. A systematic review was performed in accordance with PRISMA guidelines. Cochrane, MEDLINE and Web of Science databases were searched from inception to November 2022 for studies directly comparing drain placement to no drain placement in children ≤ 18 years of age undergoing operative treatment of complicated appendicitis. A total of 5108 children with complicated appendicitis were included from 16 studies; 2231 (44%) received a drain. Placement of a drain associated with a significantly increased risk of intra-peritoneal abscess formation (odds ratio [OR] 1.61, 95% confidence interval [CI] 1.16-2.24, p = 0.004) but there was no significant difference in wound infection rate (OR 1.46, 95% CI 0.74-2.88, p = 0.28). Length of stay was significantly longer in the drain group (mean difference 2.02 days, 95% CI 1.14-2.90, p < 0.001). Although the quality and certainty of the available evidence is low, prophylactic drain placement does not prevent intra-peritoneal abscess following appendicectomy in children with complicated appendicitis.

Abstract
Preoperative prediction of complicated appendicitis is challenging, and many clinical tools are developed to predict complicated appendicitis. This study evaluated whether a supervised learning method can recognize complicated appendicitis in emergency department (ED). Consecutive patients with acute appendicitis presenting to the ED were enrolled and included into training and testing datasets at a ratio of 70:30. The multilayer perceptron artificial neural network (ANN) models were trained to perform binary outcome classification between uncomplicated and complicated acute appendicitis. Measures of sensitivity, specificity, positive and negative likelihood ratio (LR + and LR-), and a c statistic of a receiver of operating characteristic curve were used to evaluate an ANN model. The simplest ANN model by Bröker et al. including the C-reactive protein (CRP) and symptom duration as variables achieved a c statistic value of 0.894. The ANN models developed by Avanesov et al. including symptom duration, appendiceal diameter, periappendiceal fluid, extraluminal air, and abscess as variables attained a high diagnostic performance (a c statistic value of 0.949) and good efficiency (sensitivity of 78.6%, specificity of 94.5%, LR + of 14.29, LR- of 0.23 in the testing dataset); and our own model by H.A. Lin et al. including the CRP level, neutrophil-to-lymphocyte ratio, fat-stranding sign, appendicolith, and ascites exhibited high accuracy (c statistic of 0.950) and outstanding efficiency (sensitivity of 85.7%, specificity of 91.7%, LR + of 10.36, LR- of 0.16 in the testing dataset). The ANN models developed by Avanesov et al. and H.A. Lin et al. developed model exhibited a high diagnostic performance.

Abstract
BACKGROUND Despite acute appendicitis is one of the most common surgical emergencies, its aetiology remains incompletely understood. AIM This study aimed to assess the rate at which faecoliths were present in acute appendicitis treated with appendicectomy and whether their presence was associated with complicated appendicitis. METHODS All adult patients who underwent appendicectomy for acute appendicitis in a 2 years period (January 2018 and December 2019) at a single institution were retrospectively reviewed. The presence of a faecolith was identified by at least one of three methods: pre-operative CT scan, intraoperative identification, or histopathology report. Patients were grouped according to the presence or absence of a faecolith and demographics, type of appendicitis and surgical outcomes analysed. Complicated appendicitis was defined as appendicitis with perforation, gangrene and/or periappendicular abscess formation. RESULTS A total of 1035 appendicectomies were performed with acute appendicitis confirmed in 860 (83%), of which 314 (37%) were classified as complicated appendicitis. Three hundred thirty-nine (35%) of the appendicitis cases had faecoliths (complicated 165/314 cases; 53%; uncomplicated 128/546; 23%, p < 0.001). The presence of a faecolith was associated with higher complications and a subsequent longer post-operative stay. CONCLUSION The rigorous methodology of this study has demonstrated a higher rate of faecolith presence in acute appendicitis than previously documented. It reinforces the association of faecoliths with a complicated disease course and the importance in prioritising emergency surgery and postoperative monitoring for complications.

BACKGROUND Patients with complicated appendicitis are more at risk for the occurrence of postoperative intra-abdominal abscesses than patients with uncomplicated appendicitis. Studies comparing laparoscopic and open appendectomy showed limitations and contradictory findings on the incidence of intra-abdominal abscesses after appendicitis, as most of these studies analysed both uncomplicated and complicated appendicitis as one group. The aim of the present study is to investigate the incidence of intra-abdominal abscesses after laparoscopic versus open appendectomy for complicated appendicitis. METHODS A retrospective cohort study was performed over the period January 2009 till May 2020. All patients who had an intra-operative diagnosis of complicated appendicitis (e.g. perforation, necrosis) were included. The outcome measure was the occurrence of intra-abdominal abscesses with a postoperative follow-up of 30 days. Multivariate logistic regression analysis was performed including adjustments for significant confounders. RESULTS A total of 900 patients had undergone appendectomy for complicated appendicitis. The majority was operated laparoscopically (78%, n = 705). The incidence of postoperative intra-abdominal abscess was 12.3% in both laparoscopic and open appendectomy groups. On univariable analysis, the postoperative rates of intra-abdominal abscesses between laparoscopic and open appendectomy were not significantly different (odds ratio 1.11, 95% CI [0.67-1.84], p = 0.681). CONCLUSION The present study provides evidence that, in current daily practice, intra-abdominal abscess formation remains a common postoperative complication for complicated appendicitis. Nonetheless, no significant difference was found with regard to intra-abdominal abscess formation when comparing laparoscopy with open surgery.

Abstract
BACKGROUND Acute appendicitis is classified into simple (SA) and complicated (CA). Ultrasound scans (USS) can be useful in clinically equivocal cases, by visualising primary and secondary signs. This study explores the utility of sonographic signs to diagnose and differentiate appendicitis in children. METHODS Single-centre retrospective cohort study over a 2-year period. Consecutive USS for suspected appendicitis were included; sonographic signs were extracted from standardised institutional worksheets. USS results were compared with pre-defined intraoperative criteria for SA and CA, confirmed with histological analysis. Data are reported as median [interquartile range], percentages (number), area under the curve (AUC), conventional diagnostic formulae and adjusted odds ratios following multiple logistic regression (p < 0.05 considered significant). RESULTS A total of 934 USS were included, with median age 10.7 [8.0-13.4] years, majority were female (54%). One quarter (n = 226) had SA, 12% (n = 113) had CA, 61% (n = 571) had no appendectomy and 3% (n = 24) had negative appendicectomy. Appendix visualisation rate on USS was 61% (n = 569), with 62% (n = 580) having a conclusive report. Sonographic signs suggesting appendicitis included an appendiceal diameter > 7 mm (AUC 0.92, [95% CI: 0.90-0.94]), an appendicolith (p = 0.003), hyperaemia (p = 0.001), non-compressibility (p = 0.029) and no luminal gas (p = 0.004). Secondary sonographic signs included probe tenderness (p < 0.001) and peri-appendiceal echogenic fat (p < 0.001). Sonographic signs suggesting CA over SA comprised a diameter > 10.1 mm (AUC 0.63, [95% CI: 0.57-0.69]), an appendicolith (p = 0.003) and peri-appendiceal fluid (p = 0.004). CONCLUSION Presence of specific sonographic signs can aid diagnosis and differentiation of simple and complicated appendicitis in children.

Abstract
BACKGROUND After surgery for complicated appendicitis (CA), common practice is to treat all patients with a standardised long-course of intravenous antibiotics (IVAB) to reduce the risk of postoperative surgical infections (PSI). The aim of the current study was to evaluate the safety and efficacy of a short-course IVAB after CA in selected patients. METHODS The Department's prospectively collected database identified CA patients treated between2015 and 2019. Baseline and treatment characteristics and postoperative outcomes were analysed. The cut-off between short- and long-course IVAB was 2 days. Outcomes of interest were PSI and 30-day unplanned readmission. RESULTS In total, 226 patients had CA: Ninety-nine CA (43.8%) received short-course IVAB and 127 (56.2%) received long-course. PSI occurred in 6% and 10% of the short-course and long-course patients, respectively (p = 0.34). Length of IVAB after a PSI was comparable to that of patients without PSI (median 3 and 2 days of IVAB respectively; p = 0.28). 30-day unplanned readmission rates were 7% and 6%, respectively (p = 0.99). Length of IVAB for readmitted patients was similar to those who were not readmitted (median 3 days of IVAB in both; p = 0.91). Multivariable analysis showed that the intraoperative findings of the appendix (p = 0.04) was a prognostic predictor for PSI. ASA score (p = 0.02) and surgical approach (p = 0.05) were prognostic predictors for 30-day unplanned readmission. CONCLUSIONS This study shows that when patients respond well, a short-course IVAB can safely be applied after CA without increasing risk of PSI or 30-day unplanned readmission.

Abstract
OBJECTIVE To investigate the effect of laparoscopic purse-string sutures in adult complicated appendicitis treatment. METHODS The data of 568 adult cases of complicated appendicitis treated by laparoscopic appendectomy at the Hefei Second People's Hospital, Anhui Province, China, from September 2018 to September 2021 were analysed retrospectively. The patients were divided into two groups: 295 cases in the laparoscopic purse-string suture treatment group (observation group) and 273 cases in the simple Hem-o-lok® clamp treatment group (control group). The baseline data collected included age, gender, preoperative body temperature, leukocyte count and percentage of neutrophils and the surgery time. The postoperative data collected included antibiotic treatment duration, drainage tube placement time and the incidence of complications. RESULTS There were no significant differences in the baseline data of the two groups, including age, gender, preoperative body temperature, leukocyte count and neutrophil percentage (all P > 0.05). Compared with the control group, the postoperative hospital length of stay, duration of antibiotic treatment, the recovery time of peripheral white blood cell and neutrophil counts and the incidence of postoperative complications in the observation group were significantly decreased (P < 0.05). CONCLUSION Purse-string sutures can effectively reduce the incidence of postoperative complications after a laparoscopic appendectomy for adult acute complicated appendicitis. There was faster postoperative recovery when patients' appendiceal stumps were treated with laparoscopic purse-string sutures.

Abstract
Mounting evidence suggests that acute appendicitis (AA) is not one but two diseases: complicated appendicitis, which is associated with necrosis leading to perforation or periappendicular abscess, and uncomplicated appendicitis, which does not necessarily result in perforation. Even though AA is the most frequent cause of surgery from abdominal pain, little is known about the origins and etiopathogenesis of this disease, much less regarding the different disease types. In this study, we investigated the microbiome (inter-domain amplicon and metagenome sequencing) of samples from the appendix, rectum and peritoneum of 60 children and adolescents with AA to assess the composition and potential function of bacteria, archaea and fungi. The analysis of the appendix microbial community revealed a shift depending on the severity of the AA. This shift was reflected by two major community state types that represented the complicated and uncomplicated cases. We could demonstrate that complicated, but not uncomplicated, appendicitis is associated with a significant local expansion of oral, bacterial pathogens in the appendix, most strongly influenced by necrotizing Fusobacterium spp., Porphyromonas and Parvimonas. Uncomplicated appendicitis, however, was characterized by gut-associated microbiomes. Our findings support the hypothesis that two disease types exist in AA, which cannot be distinguished beyond doubt using standard clinical characterization methods or by analysis of the patient's rectal microbiome. An advanced microbiome diagnosis, however, could improve non-surgical treatment of uncomplicated AA.

Abstract
OBJECTIVES This narrative review aims to collate the data in the existing literature on appendicoliths, by reviewing the available information on appendicoliths that have been previously reported in 24 publications, and providing the information in one article. KEY FINDINGS Appendicoliths are frequent culprits in causing luminal obstruction of the appendix, leading to appendicitis. They are calcified masses formed as a result of the aggregation of faecal particulates and inorganic salts within the lumen of the appendix. The presence of appendicoliths in an inflamed appendix influences the patient's treatment, as surgery is usually done to avoid appendix perforation and abscess formation, and also to prevent a future recurrence of the disease. Appendicoliths are mostly imaged using CT, Ultrasound, and plain X-rays; however, CT is the most frequently used modality, particularly in the imaging of complications caused by 'retained' appendicoliths. 'Retained' appendicoliths and their consequential abscesses have been reported in the sub-hepatic and intrahepatic regions, pelvic and tubo-ovarian regions, gluteal region, subcutaneous layer, subphrenic region, and through the diaphragm into the chest cavity. CONCLUSION This review provides useful information on the imaging appearances and complications caused by the presence of appendicoliths in an inflamed appendix, and it also provides information on the clinical implications of 'dropped' appendicoliths during appendectomy. IMPLICATIONS FOR PRACTICE Based on the findings of this review, it is recommended that the appropriate imaging modality (ultrasound and/or CT) should be considered when imaging appendicoliths and its complications. It is also suggested that retained appendicolith be considered a differential diagnosis when imaging patients with a history of appendectomy due to complicated appendicitis/perforation.

Abstract
BACKGROUND Acute appendicitis in children refers to the acute inflammation of the appendix, which accounts for 20% ∼ 30% of cases of acute abdomen in pediatric surgery. OBJECTIVE This study aimed to establish a decision tree model of complicated appendicitis in children using appendiceal ultrasound combined with an inflammatory index and evaluated its clinical efficacy in pediatric patients. METHODS A total of 395 children admitted to the Emergency Department of the Shanghai Children's Hospital from January 2018 to December 2021 and diagnosed with appendicitis by postoperative pathology were retrospectively analyzed. According to the postoperative pathology, the children were divided into a complicated and non-complicated appendicitis group, respectively. Routine laboratory inflammatory indicators, including white blood cell count, N(%), neutrophil (Neu) count, Neu/lymphocyte ratio (NLR), C-reactive protein (CRP), and procalcitonin were collected from the two groups. Collecting data on ultrasound examination of the appendix includes whether the appendix diameter is thickened, whether the echogenicity of the mesenteric rim surrounding the appendix is enhanced, whether there is rich blood supply in the appendix, and whether there are fecaliths in the appendix lumen. The risk factors for complicated appendicitis were screened out by univariate and multivariate logistic regression analyses, the binary logistic regression prediction and decision tree models were established, respectively, and the receiver operating characteristic (ROC) curve was used to verify the accuracy of the two prediction models. RESULTS Binary logistic regression analysis showed that CRP, NLR, the presence of an appendicolith, and peripheral retina echo enhancement were independent risk factors for complicated appendicitis in children (P< 0.05). The decision tree model had an overall accuracy of 79%, an area under the ROC curve (AUC) of 0.809 (95% confidence interval [CI] 0.780-0.865), and sensitivity and specificity of 71.3% and 77.7%, respectively. The logistic regression model had an overall accuracy of 74.9%, an AUC value of 0.823 (95% CI, 0.765-0.853), a sensitivity value of 80.3%, and a specificity of 71.8%. CONCLUSION This predictive model, based on ultrasound of the appendix combined with inflammatory markers, provides a useful method to assist pediatric emergency physicians in diagnosing childhood appendicitis. The decision tree model reflected the interaction of various indexes, and the model was simple, intuitive, and effective.

Abstract
Background The COVID-19 pandemic period suggests that the rate of complications may have increased in patients requiring surgical treatment due to the fact that they could not come to the hospital at the onset of the symptom. This study aims to evaluate the difference in the frequency of complicated appendicitis and postoperative complications in the COVID-19 pandemic.Patients included those who underwent appendectomy in 1 year before the COVID-19 pandemic and in the first year of the pandemic. The patients were categorized into two groups: pre-pandemic and pandemic periods. Clinical and histopathology results were compared between the pre-pandemic and pandemic periods. Results A total of 407 patients were included in the study, 207 of whom were included during the pre-pandemic and 200 of whom during the pandemic period. The mean time to hospital admission after the onset of symptoms was 1.3 ± 0.9 days, pre-pandemic, and 1.4 ± 0.8 days during the pandemic group. In the pre-pandemic group, 0.4% intrabdominal abscess developed and 37.5% complicated appendicitis was detected. In the pandemic group, it was found that there were 1% abscess, 0.5% wound infection, 0.5% brid ileus, and 31.9% complicated appendicitis. The pre-pandemic group length of hospitalization was 2.4 ± 0.8 days, and the pandemic was 2.1 ± 0.9 days There was no difference between pre-pandemic and pandemic groups in terms of age, gender, white blood cell count, duration of symptoms, postoperative complications and frequency of complicated appendicitis, and duration of hospitalization. Conclusions In the first year of the COVID-19 pandemic, we found that the rate of complicated appendicitis and postoperative complications were not different from pre-pandemic.

Abstract
BACKGROUND Acute appendicitis often presents with vague abdominal pain, which fosters diagnostic challenges to clinicians regarding early detection and proper intervention. This is even more problematic with individuals with severe psychiatric disorders who have reduced sensitivity to pain due to long-term or excessive medication use or disturbed bodily sensation perceptions. This study aimed to determine whether psychiatric disorder, psychotropic prescription, and treatment compliance increase the risks of complicated acute appendicitis. METHODS The diagnosis records of acute appendicitis from four university hospitals in Korea were investigated from 2002 to 2020. A total of 47,500 acute appendicitis-affected participants were divided into groups with complicated and uncomplicated appendicitis to determine whether any of the groups had more cases of psychiatric disorder diagnoses. Further, the ratio of complicated compared to uncomplicated appendicitis in the mentally ill group was calculated regarding psychotropic dose, prescription duration, and treatment compliance. RESULTS After adjusting for age and sex, presence of psychotic disorder (odds ratio [OR]: 1.951; 95% confidence interval [CI]: 1.218-3.125), and bipolar disorder (OR: 2.323; 95% CI: 1.194-4.520) was associated with a higher risk of having complicated appendicitis compared with absence of psychiatric disorders. Patients who are taking high-daily-dose antipsychotics, regardless of prescription duration, show high complicated appendicitis risks; High-dose antipsychotics for < 1 year (OR: 1.896, 95% CI: 1.077-3.338), high-dose antipsychotics for 1-5 years (OR: 1.930, 95% CI: 1.144-3.256). Poor psychiatric outpatient compliance was associated with a high risk of complicated appendicitis (OR: 1.664, 95% CI: 1.014-2.732). CONCLUSIONS This study revealed a close relationship in the possibility of complicated appendicitis in patients with severe psychiatric disorders, including psychotic and bipolar disorders. The effect on complicated appendicitis was more remarkable by the psychiatric disease entity itself than by psychotropic prescription patterns. Good treatment compliance and regular visit may reduce the morbidity of complicated appendicitis in patients with psychiatric disorders.

Abstract
BACKGROUND Interval appendectomy or non-operative management is commonly performed for complicated appendicitis in adult patients. However, these treatments are still controversial because the incidence rate of appendiceal tumors recognized after interval appendectomy is reportedly higher than that after emergency appendectomy. Thus, this study aimed to compare the appendiceal tumor rates between uncomplicated and complicated appendicitis. METHODS This study was a retrospective review of patients with appendicitis who underwent surgical removal at a single institution over 7.5 years. The primary objective was the comparison of the incidence rate of appendiceal tumors using propensity score matching, and the secondary objective was the same comparison among older patients, defined as patients aged ≥ 60 years. RESULTS A total of 1277 patients were included. Of these patients, 297 (23.3%) were preoperatively diagnosed with complicated appendicitis. Moreover, 22 (1.7%) patients, including 14 cases of complicated appendicitis and 8 cases of uncomplicated appendicitis, were diagnosed with appendiceal tumors based on pathological examination. No significant difference was found in the incidence rate of appendiceal tumors between the two groups after matching for patients' background, including age, sex, and history of appendicitis by propensity score matching (P = 0.073). However, among patients aged ≥ 60 years, the incidence of appendiceal tumors was significantly higher in complicated than in uncomplicated appendicitis (P = 0.006). CONCLUSIONS Although the overall risk of appendiceal tumors did not differ between complicated and uncomplicated appendicitis when analyzed by the propensity score matching, in older patients aged ≥ 60 years, the risk increased among those with complicated appendicitis. Therefore, although the incidence is low, complicated appendicitis, particularly, among older patients, should be examined carefully and be performed IA when unusual findings exist.

Abstract
PURPOSE This was a pilot randomised, prospective study, which aimed to determine and compare the post-operative complications of paediatric patients undergoing laparoscopic appendectomy (LA) for complicated appendicitis, with and without a peritoneal drain. METHODS Patients younger than 13 years, undergoing LA for complicated appendicitis at the Dr George Mukhari Academic Hospital (DGMAH), over a 15-month period during 2019-2020 were enrolled. Randomisation was achieved by a blocked randomisation plan. Patients were randomised in a 1:1 ratio into the "drain" (D) and "no drain" (ND) groups. RESULTS Thirty-four patients were included in this study; seventeen in each group. The complication rate was 26%. Intra-abdominal collection accounted for 89% of the complications. The complication rate in the "D" group was 18% and 35% in the "ND" group, with no statistically significant difference. Complication rates were higher (38%) in patients with generalised pus when compared to localised pus (7%), although not statistically significant. The mean theatre time, hospital stay, and duration of antibiotic use did not differ significantly between the groups. CONCLUSION From our study, the post-operative peritoneal drain did not make any statistically significant difference in patient outcome. The amount of intra-abdominal contamination is more likely to contribute in the development of complications. TRIAL REGISTRATION NUMBER SMUREC/M/15/2019: PG.

Abstract
PURPOSE To systematically summarize all relevant data and to define the current evidence on the utility of Pentraxin-3 (PTX3) as a biomarker for acute appendicitis (AA) in children. METHODS This review was conducted in accordance with the PRISMA guidelines. PubMed, Embase, Scopus, and Web of Science databases were systematically searched for studies comparing the levels of PTX3 in patients with AA vs healthy controls or non-specific abdominal pain (NSAP). Mean differences were calculated for all outcomes and the inverse variance method was used for weighted mean difference. The methodological quality of the included studies was assessed using the Downs and Black scale. RESULTS Five comparative studies were included. Significantly elevated levels of PTX3 in cases with AA vs healthy controls (WMD: 9.56, 95% CI 7.24-11.88, p < 0.00001), and patients with AA vs NSAP (WMD: 8.05, 95% CI 6.81-9.29, p < 0.00001) were demonstrated. Similarly, in separate meta-analyses, the levels of PTX3 were significantly elevated in children with AA vs healthy controls (WMD: 11.18, 95% CI 10.03-12.34, p < 0.00001), and children with AA vs NSAP (WMD: 8.35, 95% CI 6.88-9.82, p < 0.00001). CONCLUSIONS PTX3-levels are elevated in AA, but differentiation between perforated and non-perforated appendicitis demands other methods.

Abstract
Purpose An increase in the incidence of pediatric complicated appendicitis (CA) during the COVID-19 pandemic has been reported in many countries. We investigated how the pandemic has affected Japan. Methods We retrospectively reviewed children of ≤ 15 years old treated for acute appendicitis across 5 medical centers during the pandemic period (January to October in 2020), with the pre-pandemic period (January to October in 2017 to 2019) evaluated as a historical control. The incidence of CA and disease characteristics were then compared between the periods. Results The total number of patients was 55 in 2020 and 192 in 2017–2019. In all centers, the incidence of acute pediatric CA in the pandemic period significantly increased compared to the pre-pandemic period (18.2% vs. 32.7%, p = 0.02). On limiting our evaluation to the 3 institutions with reductions in patient numbers, the incidence of CA increased (16.3% vs. 37.9%, p = 0.01), and the duration of pre-operative symptoms was prolonged (1.3% vs. 1.7 days, p = 0.03). There were no significant differences in the age, sex, white blood cell count, C-reactive protein, or body temperature. No cases were diagnosed with SARS-CoV-2. Conclusions The incidence of acute pediatric CA increased during the pandemic period. This may be related to an extended duration of symptoms due to individuals fearing contracting COVID-19 while visiting a hospital.

Abstract
BACKGROUND Antibiotic choice for complicated appendicitis should be based on both microbiological effectiveness as well as ease of administration and cost especially in lower resourced settings. Data is limited on comparative morbidity outcomes for antibiotics with similar microbiological spectrum of activity. Incidence and morbidity of surgical site infection after appendectomy for complicated appendicitis was assessed after protocol change from triple antibiotic (ampicillin, gentamycin, and metronidazole) regimen to single agent (amoxycillin/clavulanic acid). METHODS Surgical site infection (SSI) rate, relook surgery rate and length of hospital stay were retrospectively compared in patients treated for acute appendicitis preceding (2014, 2015; "triple-therapy, TT") and following (2017, 2018; "single agent, SA") antibiotic protocol change. RESULTS The rate of complicated appendicitis was similar between groups; 72.6% in TT and 66% in SA (p = 0.239). Significantly, SSI occurred in 22.7% of the SA group compared to 13.3% in TT group (OR 1.920, 95% CI 1.000-3.689, p = 0.048). Use of laparoscopy increased from 31% in TT to 89% in SA, but with subgroup analysis this was not associated with increased SSI (17.3% in open and 20.6% in laparoscopic; OR 0.841, 95% CI 0.409-1.728, p = 0.637). Relook rate (OR 1.444, 95% CI 0.595-3.507, p = 0.093) length of hospital stay (U = 6859, z = -1.163, p = 0.245), and ICU admission (U = 7683, z = 0.634 p = 0.522) were equivocal. Neither group had mortalities. CONCLUSIONS Despite increased SSI with SA, overall morbidity relating to ICU admission, relook rate and length of hospital stay was similar in both groups. More prospective research is required to confirm equivalent overall morbidity and that single agent therapy is more cost-effective with acceptable clinical outcomes.

Abstract
PURPOSE The pre-interventional differentiation between complicated and uncomplicated appendicitis is decisive for treatment. In the context of conservative therapy, the definitive diagnosis of uncomplicated appendicitis is mandatory. This study investigates the ability of clinical scoring systems and imaging to differentiate between the two entities. METHODS This is a retrospective analysis of two cohorts from two tertiary referral centers in Switzerland and Germany. All consecutive patients underwent appendectomy between January 2008 and April 2013 (in the first cohort) or between January 2017 and June 2019 (the second cohort). Exclusion criteria did not apply as all patients found by the database search and received an appendectomy were included. Diagnostic testing and calculation of a receiver operating curve were performed to identify a cutoff for clinical scores that resulted in a minimum sensitivity of 90% to detect complicated appendicitis. The cutoff was combined with additional diagnostic imaging criteria to see if diagnostic properties could be improved. RESULTS Nine hundred fifty-six patients were included in the analysis. Two hundred twenty patients (23%) had complicated appendicitis, and 736 patients (77%) had uncomplicated appendicitis or no inflammation. The complicated appendicitis cohort had a mean Alvarado score of 7.03 and a mean AIR of 5.21. This compared to a mean Alvarado of 6.53 and a mean AIR of 4.07 for the uncomplicated appendicitis cohort. The highest Alvarado score with a sensitivity of > 90% to detect complicated appendicitis was ≧ 5 (sensitivity = 95%, specificity 8.99%). The highest AIR score with a sensitivity of > 90% to detect complicated appendicitis was ≧ 3 (sensitivity 91.82%, specificity 18.53). The analysis showed that additional CT information did not improve the sensitivity of the proposed cut-offs. CONCLUSION AIR and Alvarado scores showed limited capability to distinguish between complicated and uncomplicated appendicitis even with additional imaging in this retrospective cohort. As conservative management of appendicitis needs to exclude patients with complicated disease reliably, appendectomy seems until now to remain the safest option to prevent undertreatment of this mostly benign disease.

Abstract
INTRODUCTION Complicated appendicitis is a common cause of morbidity in children. Studies have analyzed the risk factors in the surgical treatment of this pathology, including obesity and disease severity, but not operative time (OT). We hypothesize that OT is independently associated with increased morbidity for children with complicated appendicitis. METHODS Data were extracted from the 2018 and 2019 National Surgical Quality Improvement Program-Pediatrics data sets. Patients aged 2-18 y who underwent laparoscopic appendectomy for complicated appendicitis were identified. Patient demographics, disease severity, and operative details were evaluated. Surgical site infections (SSIs), hospital length of stay (LOS), ≤30-d readmissions and reoperations, interventional radiologic drain (IR-drain) placement, pneumonia, and death were analyzed. Logistic and linear regression analyses were performed. RESULTS A total of 8168 patients were analyzed, with a mean age of 9.96 ± 3.9 y and a mean weight of 41.2 ± 21.2 kg. The mean OT was 55.8 ± 24.9 min, with a mean LOS of 5.15 ± 3.37 d. For every 1-min increase in OT, there was an independently associated increase in the likelihood of any SSI (odds ratio [OR] = 1.01; 95% confidence interval [CI] 1.008-1.013), superficial SSI (OR = 1.01; 95% CI 1.004-1.020), organ-space SSI (OR = 1.01; 95% CI 1.008-1.013), IR-drain placement (OR = 1.01; 95% CI 1.008-1.013), and readmission (OR = 1.004; 95% CI 1.000-1.007). CONCLUSIONS Prolonged OT is independently associated with greater likelihood of any SSI, superficial SSI, organ-space SSI, IR-drain placement, readmission and reoperation within 30 d, and longer hospital LOS. There is a need to determine modifiable factors that prolong OT to aid in the optimization of routine operations to reduce patient morbidity.

Abstract
BACKGROUND Laparoscopic appendectomy (LA) is the preferred approach in uncomplicated appendicitis. However, in patients with complicated appendicitis (CA), the best approach is still unclear though laparoscopy is being increasingly preferred over open appendicectomy (OA) nowadays. AIM To comprehensively review the current literature and compare the associations of LA and OA concerning various postoperative outcomes in order to determine the best approach for children with CA. METHODS The PRISMA guidelines were adhered to and an electronic database search was extensively performed. Data analysis, including subgroup analysis of randomized-control trials, was performed using RevMan 5.3. Methodological and statistical heterogeneity, as well as publication bias of the included studies, were assessed. RESULTS Four randomized controlled trials (266 LA versus 354 OA) and thirty-six case-controlled trials (2580 LA versus 3043 OA) were included in the analysis. Compared to OA, LA has a shorter length of stay, a lower rate of surgical site infection as well as a significantly lower overall complication rate. The rates of intraabdominal abscess formation, post-operative fever, pneumonia and ileus are similar in the two groups. So are the rates of readmissions and reoperations. LA was also shown to have a shorter time taken to oral intake and a lesser requirement of analgesics as well as intravenous antibiotics. Operative time for OA was found to be significantly shorter than that for LA. CONCLUSION This meta-analysis objectively demonstrates that laparoscopy has a better overall complication profile compared to OA and should be the procedure of choice in children with complicated appendicitis.

Abstract
INTRODUCTION Multiple factors signifying higher social vulnerability, including lower socioeconomic status and minority race, have been associated with presentation with complicated appendicitis (CA). In this study, we compared the Social Vulnerability Index (SVI) of our population by appendicitis severity (uncomplicated appendicitis [UA] versus CA). We hypothesized that SVI would be similar between patients with UA and CA presenting to our institution, a safety-net hospital in a state with high healthcare insurance coverage. METHODS We included all patients at our hospital aged 18 y and older who underwent appendectomy for acute appendicitis between 2012 and 2016. SVI values were determined based on the 2010 census data using ArcMap software. We used nonparametric univariate statistics to compare the SVI of patients with CA versus UA and multivariable regression to model the likelihood of operative CA. RESULTS A total of 997 patients met inclusion criteria, of which 177 had CA. The median composite SVI score for patients with CA was lower than for patients with UA (80% versus 83%, P = 0.004). UA was associated with higher socioeconomic (83% versus 80%, P = 0.007), household/disability (68% versus 55%, P = 0.037), and minority/language SVI scores (91% versus 89%, P = 0.037). On multivariable analysis controlling for age, sex, ethnicity, insurance status, relevant comorbidities, and chronicity of symptoms, there was an inverse association between SVI and the likelihood of CA (odds ratio 0.59, 95% confidence interval 0.4-0.87, P = 0.008). CONCLUSIONS In the setting of high healthcare insurance and a medical center experienced in caring for vulnerable populations, patients presenting with UA have a higher composite SVI, and thus greater social vulnerability, than patients presenting with CA.

Abstract
Purpose Appendectomy for acute appendicitis is one of the most common operative procedures worldwide in both children and adults. In particular, complicated (perforated) cases show high variability in individual outcomes. Here, we developed and validated a machine learning prediction model for postoperative outcome of perforated appendicitis. Methods Retrospective analyses of patients with clinically and histologically verified perforated appendicitis over 10 years were performed. Demographic and surgical baseline characteristics were used as competing predictors of single-patient outcomes along multiple dimensions via a random forest classifier with stratified subsampling. To assess whether complications could be predicted in new, individual cases, the ensuing models were evaluated using a replicated 10-fold cross-validation. Results A total of 163 patients were included in the study. Sixty-four patients underwent laparoscopic surgery, whereas ninety-nine patients got a primary open procedure. Interval from admission to appendectomy was 9 ± 12 h and duration of the surgery was 74 ± 38 min. Forty-three patients needed intensive care treatment. Overall mortality was 0.6 % and morbidity rate was 15%. Severe complications as assessed by Clavien-Dindo > 3 were predictable in new cases with an accuracy of 68%. Need for ICU stay (> 24 h) could be predicted with an accuracy of 88%, whereas prolonged hospitalization (greater than 7–15 days) was predicted by the model with an accuracy of 76%. Conclusion We demonstrate that complications following surgery, and in particular, health care system-related outcomes like intensive care treatment and extended hospitalization, may be well predicted at the individual level from demographic and surgical baseline characteristics through machine learning approaches.

Abstract
BACKGROUND Radiologic imaging can accurately diagnose acute appendicitis, but little is known about its discriminatory capacity between complicated and uncomplicated appendicitis. OBJECTIVE This study aims to investigate the accuracy of imaging in discriminating complicated from uncomplicated appendicitis. METHODS Data was used from the prospective, nationwide, observational SNAPSHOT appendicitis database, including patients with suspected acute appendicitis who were planned for an appendectomy. Usage of ultrasound (US), CT, MRI or a combination was recorded. Radiological reports were used to group for complicated or uncomplicated appendicitis. The reference standard was based on operative and pathological findings. Primary outcomes were sensitivity and specificity in discriminating complicated from uncomplicated appendicitis. Secondary outcomes were diagnostic accuracy results per imaging modality and for the subgroups age, BMI, and sex. RESULTS Preoperative imaging was performed in 1964 patients. In 1434 patients (73%), only US was used; in 109 (6%) patients, only CT was used; and 421 (21%) patients underwent US followed by CT or MRI. Overall, imaging workup as practiced, following the national guideline, had a poor sensitivity for complicated appendicitis of only 35%, although specificity was as high as 93%. For US, accuracy for complicated appendicitis was higher in children than in adults; sensitivity 41.2% vs. 26.4% and specificity 94.6% vs. 93.4%, respectively, p = 0.003. For relevant subgroups such as age, sex and BMI, no other differences in the discriminatory performance were found. CONCLUSION A diagnostic workup with stepwise imaging, using a conditional CT or MRI strategy, poorly discriminates between complicated and uncomplicated appendicitis in daily practice.

Abstract
Background This study examined whether drain placement or not is associated with the postoperative outcomes of pediatric patients following trans-umbilical single-port laparoscopic appendectomy (TUSPLA) for complicated appendicitis. Methods
The medical records of pediatric patients undergoing TUSPLA for acute complicated appendicitis from January 2012 to September 2018 in Kaohsiung Chang Gung Memorial Hospital were reviewed retrospectively. They were classified according to whether they received passive drainage with a Penrose drain (Penrose group) (19), active drainage with a Jackson-Pratt drain with a vacuum bulb (JP group) (16), or no drain (non-drain group) (86). The postoperative outcomes of the three groups were compared. Results Postoperative visual analog scale pain score was significantly higher in the non-drain group than in either the JP group or Penrose group. Patients in the Penrose group had a significantly longer postoperative hospital stay than those in the non-drain group and a higher rate of intra-abdominal abscess, while patients in the JP group had a significantly shorter postoperative hospital stay; moreover, no patient in JP group developed a postoperative intra-abdominal abscess. Conclusions Compared to passive drainage with a Penrose drain or no drain, active drainage with a JP drain shorter the postoperative hospital stay and decreased the risk of postoperative intra-abdominal abscess.

Abstract
PURPOSE No reliably specific marker for complicated appendicitis has been identified. The ratio of serum C-reactive protein (CRP) to albumin (ALB) (CRP/ALB ratio) is a new inflammation-based prognostic score that is associated with the severity of inflammation. The aim of this study was to evaluate the predictive value of CRP/ALB ratio for the diagnosis of complicated appendicitis in children. METHODS A retrospective study of 296 children with acute appendicitis was conducted with assessments of demographic data, clinical symptoms, pre-operative laboratory results, abdominal ultrasound examinations and clinical outcomes. According to the postoperative pathological results, patients were divided into a simple appendicitis group (169 patients) and a complicated appendicitis group (127 patients). SPSS version 22.0 was used to analyse the data. RESULTS Of the 296 patients, CRP/ALB ratio was higher in complicated appendicitis than in simple appendicitis (P < 0.05). Logistic regression analysis showed that higher levels of white blood cell count (WBC), CRP, CRP/ALB ratio, and increased incidence in submucosal layer loss and appendicolith were independent risk factors for complicated appendicitis in children. Receiver operating characteristic curve analysis showed that the area under the curve of the CRP/ALB ratio (0.883) was larger than that of WBC (0.702), CRP (0.802), ALB (0.835), submucosal layer loss (0.633) and appendicolith (0.673). A CRP/ALB ratio ≥ 1.39 was found to be a significant marker in the prediction of complicated appendicitis, with 86.61% sensitivity and 84.62% specificity. Patients with a CRP/ALB ratio ≥ 1.39 had a 31.263 times higher chance of having complicated appendicitis (95% CI: 16.449-59.418) than those with a CRP/ALB ratio < 1.39. CONCLUSION The admission CRP/ALB ratio was significantly higher in children with complicated appendicitis. The CRP/ALB ratio is a novel but promising haematological marker that aids in the differentiation of acute complicated and simple appendicitis.

Abstract
PURPOSE Acute appendicitis (AA) is amongst the most common causes of acute abdominal pain. In spite of progress based on risk stratifications, "negative" appendectomies are performed in up to 30% of patients whilst the appendix perforates in others. Preoperative classification of AA based on imaging is therefore recommended. The aim was to classify AA based on imaging (ultrasound/US, computed tomography/CT), surgical pathology, and/or histopathology in order to differentiate between complicated and uncomplicated AA. A new classification of acute appendicitis (CAA) shall be illustrated by typical US and CT images and be employed in a diagnostic and therapeutic algorithm. METHODS Medline, Embase, and the Cochrane Library were searched. Any study after 1970, which investigated clinical scores, pathology, US, CT, magnetic resonance imaging, and treatment of AA, was included. Typical images were taken from the author's image database. RESULTS Five main types of AA are defined, normal appendix (type 0), nonvisualised appendix (type X), uncomplicated AA (type 1), complicated AA without perforation (type 2), and complicated AA with perforation (type 3). The imaging modality is indicated by an additional letter, e.g., type p3b for free perforation on pathology. Standardised reporting of the appendix evaluation by US and CT is presented, as well as algorithms for AA management. Imaging features indicating imminent perforation, as well as likely recurrence, were both classified as complicated AA. CONCLUSION Imaging is mandatory in suspected AA. The CAA clearly separates uncomplicated from complicated forms of AA allowing nonoperative management in selected patients with uncomplicated forms of AA.
