[PMID: 39070943 PMCID: PMC11278374 DOI: 10.1515/med-2024-1002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 06/20/2024] [Accepted: 06/22/2024] [Indexed: 07/30/2024] Open
Abstract
Introduction Acute appendicitis (AA) is the predominant condition responsible for acute abdominal pain across all age demographics. The purpose of this research is to determine if the hemoglobin, albumin, lymphocyte, and platelet (HALP) and modified HALP (m-HALP) scores differ between complicated and uncomplicated appendicitis in patients diagnosed with AA who have applied to the emergency department (ED). Additionally, this study aims to investigate whether HALP and m-HALP scores are superior to other biomarkers. Materials and methods The retrospective analysis included adult patients, aged eighteen or older, who were diagnosed with AA, and sought treatment at the ED of a tertiary hospital. Patients were divided into two groups: complicated appendicitis (CA) and uncomplicated appendicitis (UCA). The cut-off in diagnostic value measurements was determined using the receiver operating characteristic analysis. Results A total of 436 patients (CA: 126, UCA: 310) were included. Neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-albumin ratio, systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and pan-immune inflammation value (PIV) were found to have acceptable diagnostic power in CA detection (area under the curve [AUC]: 0.735-0.783). In detecting UCA, HALP and m-HALP were of fair diagnostic power (AUC: 0.64, 0.68, respectively). Conclusions In this study, we found that although PIV, SIRI, SII, and NLR had acceptable diagnostic values in distinguishing CA and UCA, HALP and m-HALP had fair diagnostic values.

[PMID: 38928671 PMCID: PMC11203331 DOI: 10.3390/diagnostics14121256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 06/03/2024] [Accepted: 06/11/2024] [Indexed: 06/28/2024] Open
Abstract
BACKGROUND Acute appendicitis is a common abdominal emergency observed in emergency departments (ED). Distinguishing between uncomplicated and complicated appendicitis is important in determining a treatment strategy. Serum soluble vascular cell adhesion molecule-1 (VCAM-1) is an inflammatory biomarker. We aimed to determine the role of VCAM-1 in predicting complicated appendicitis in children. METHODS Pediatric patients with suspected appendicitis admitted to the ED were enrolled in this prospective study. Pre-surgical serum VCAM-1 was tested in children with acute appendicitis within 72 h of symptoms (from day 1 to day 3). Serum VCAM-1 levels were further analyzed and compared between patients with and without complicated appendicitis. RESULTS Among the 226 pediatric appendicitis patients, 70 had uncomplicated appendicitis, 138 had complicated appendicitis, and 18 had normal appendices. The mean serum VCAM-1 levels in patients with perforated appendicitis were higher than in those with simple appendicitis (p < 0.001). On day 1 to day 3, the mean VCAM-1 levels in patients with complicated appendicitis were all significantly higher than in those with uncomplicated appendicitis (all p < 0.001). CONCLUSION Serum VCAM-1 levels may be helpful in differentiating uncomplicated and complicated appendicitis in children and could predict appendiceal perforation.

Abstract
The identification of pediatric appendicitis is challenging due to the lack of specific markers thereby several factors are included in the diagnostic process such as abdominal pain, ultrasonography and altered laboratory parameters (C reactive protein, absolute neutrophil cell number and white blood cell number). The glycosylation pattern of serum N-glycome was analyzed in this study of 38 controls and 40 patients with pediatric appendicitis. The glycans were released by enzymatic deglycosylation followed by fluorescent labeling and solid-phase extraction. The prepared samples were analyzed by hydrophilic interaction liquid chromatography with fluorescence and mass-spectrometric detection. The generated data were analyzed by multiple statistical tests involving the most important laboratory parameters as well. Significant differences associated with the examined patient groups were revealed suggesting the potential use of glycosylation analysis supporting the detection of pediatric appendicitis.

Abstract
Importance When considering nonoperative treatment in a patient with acute appendicitis, it is crucial to accurately rule out complicated appendicitis. The Atema score, also referred to as the Scoring System of Appendicitis Severity (SAS), has been designed to differentiate between uncomplicated and complicated appendicitis but has not been prospectively externally validated. Objective To externally validate the SAS and, in case of failure, to develop an improved SAS (2.0) for estimating the probability of complicated appendicitis. Design, Setting, and Participants This prospective study included adult patients who underwent operations for suspected acute appendicitis at 11 hospitals in the Netherlands between January 2020 and August 2021. Main Outcomes and Measures Appendicitis severity was predicted according to the SAS in 795 patients and its sensitivity and negative predictive value (NPV) for complicated appendicitis were calculated. Since the predefined targets of 95% for both were not met, the SAS 2.0 was developed using the same cohort. This clinical prediction model was developed with multivariable regression using clinical, biochemical, and imaging findings. The SAS 2.0 was externally validated in a temporal validation cohort consisting of 565 patients. Results In total, 1360 patients were included, 463 of whom (34.5%) had complicated appendicitis. Validation of the SAS resulted in a sensitivity of 83.6% (95% CI, 78.8-87.6) and an NPV of 85.0% (95% CI, 80.6-88.8), meaning that the predefined targets were not achieved. Therefore, the SAS 2.0 was developed, internally validated (C statistic, 0.87; 95% CI, 0.84-0.89), and subsequently externally validated (C statistic, 0.86; 95% CI, 0.82-0.89). The SAS 2.0 was designed to calculate a patient's individual probability of having complicated appendicitis along with a 95% CI. Conclusions and Relevance In this study, external validation of the SAS fell short in accurately distinguishing complicated from uncomplicated appendicitis. The newly developed and externally validated SAS 2.0 was able to assess an individual patient's probability of having complicated appendicitis with high accuracy in patients with acute appendicitis. Use of this patient-specific risk assessment tool can be helpful when considering and discussing nonoperative treatment of acute appendicitis with patients.

Abstract
Introduction Acute appendicitis (AA) represents the most frequent surgical emergency. Perforation was long considered the ultimate outcome of AA, prompting appendectomy; which remains the standard treatment. New data have clarified the role of the appendix, justifying conservative treatment. This narrative review aims to summarize the evidence regarding the non-operative treatment (NOT) of AA in adults. Methods The literature search was performed via the PubMed Medline database. Our criteria-based selection resulted in a total of 48 articles for review. Results Recent trials and meta-analyses have assessed NOT, which support primary antibiotic treatment of uncomplicated AA. Although it has a significant recurrence and failure rate, NOT does not appear to increase the risk of appendicular perforation. Moreover, NOT compared with appendectomy, seems to be associated with less morbidity, lower cost of care and preserved quality of life. Conclusion First-line NOT seems to be a reasonable approach for the treatment of uncomplicated CT-confirmed AA. Careful patient screening would definitely enhance the success rate.

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

Abstract
PURPOSE To determine the accuracy of final judgements of doctors at the emergency department (ED) and radiologists to differentiate between complicated and uncomplicated acute appendicitis, because these have different treatment options. METHODS This prospective, multicenter study included adult patients with imaging-confirmed acute appendicitis, operated with intention to appendectomy. Both doctors at ED and radiologists assessed appendicitis severity as a final judgement of "uncomplicated" or "complicated" appendicitis. Doctors at ED integrated clinical, laboratory, and imaging findings. Radiologists relied solely on imaging findings. Outcomes were accuracy of these judgements for diagnosis of complicated appendicitis compared to the reference standard by an adjudication committee. RESULTS After imaging, 1070 patients with confirmed acute appendicitis were included. Doctors at ED accurately labelled 656 of 701 (93.6%) patients with true uncomplicated appendicitis as uncomplicated, and 163 of 369 (44.2%) patients with true complicated appendicitis were labelled as complicated. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) for complicated appendicitis were 44.2%, 93.6%, and 78.4% and 76.1%, respectively. Comparable accuracy was found for the radiologist's assessment in 941 patients, with true positive rates of 92.2% (581 of 630 patients) for uncomplicated appendicitis and 46.6% (145 of 311 patients) for complicated appendicitis. CONCLUSION More than half of all patients with true complicated appendicitis is incorrectly classified as uncomplicated appendicitis according to the judgements of doctors at ED, integrating clinical, laboratory, and imaging results, and of radiologists assessing diagnostic imaging. These judgements are thereby not sufficiently reliable in ruling out complicated appendicitis.

Abstract
BACKGROUND Appendectomy remains a common pediatric surgical procedure with an estimated 80,000 operations performed each year. While prior work has reported the existence of racial disparities in postoperative outcomes, we sought to characterize potential income-based inequalities using a national cohort. METHODS All non-elective pediatric (<18 years) hospitalizations for appendectomy were tabulated in the 2016-2020 National Inpatient Sample. Only those in the highest (HI) and lowest income (LI) quartiles were considered for analysis. Multivariable regression models were developed to assess the independent association of income and postoperative major adverse events (MAE). RESULTS Of an estimated 87,830 patients, 36,845 (42.0%) were HI and 50,985 (58.0%) were LI. On average, LI patients were younger (11 [7-14] vs 12 [8-15] years, P < .001), more frequently insured by Medicaid (70.7 vs 27.3%, P < .05), and more commonly of Hispanic ethnicity (50.8 vs 23.4%, P < .001). Following risk adjustment, the LI cohort was associated with greater odds of MAE (adjusted odds ratio [AOR] 1.30 95% confidence interval [CI] 1.06-1.64). Specifically, low-income status was linked with increased odds of infectious (AOR 1.65, 95% CI 1.12-2.42) and respiratory (AOR 1.67, 95% CI 1.06-2.62) complications. Further, LI was associated with a $1670 decrement in costs ([2220-$1120]) and a +.32-day increase in duration of stay (95% CI [.21-.44]). CONCLUSION Pediatric patients of the lowest income quartile faced increased risk of major adverse events following appendectomy compared to those of highest income. Novel risk stratification methods and standardized care pathways are needed to ameliorate socioeconomic disparities in postoperative outcomes.

Abstract
BACKGROUND Regional inflammation-induced local vasodilation may exist in cases of appendicitis. In this study, the diameters of the ileocolic artery (ICA) and ileocolic vein (ICV) were measured using contrast-enhanced abdominal computed tomography (CT) scans in acute appendicitis cases. The study aimed to measure the diagnostic value of these measurements in the diagnosis of acute appendicitis. MATERIAL AND METHODS A total of 508 patients, including those with a diagnosis of acute appendicitis and a control group without appendicitis, were systematically evaluated. In all cases, the appendix was analyzed simultaneously on axial and coronal CT sections, and all measurement procedures were conducted with an electronic ruler after the actual images were magnified. Measurements of the ICA and ICV diameters were taken from the proximal 2-cm segments of the superior mesenteric artery and superior mesenteric vein in the axial plane. Demographic information, sex distribution, and ICA and ICV diameters were collected. RESULTS Of the 508 patients, 53.74% were men, and 46.26% were women. ICA and ICV diameters were significantly increased in the appendicitis group (P<0.001). Binomial logistic regression confirmed the independent predictive value of ICA and ICV diameters. Receiver operating characteristic curve analysis determined optimal cut-off values for distinguishing between the non-appendicitis and appendicitis groups (ICA: 2.475 mm, ICV: 3.885 mm) with high sensitivity and specificity. CONCLUSIONS ICA and ICV diameter measurements, in conjunction with major radiological findings, can enhance diagnostic accuracy in acute appendicitis cases. The use of ICA and ICV diameter measurements in diagnosing acute appendicitis offers a novel perspective in clinical practice.

Abstract
To investigate the radiomics models for the differentiation of simple and non-simple acute appendicitis. This study retrospectively included 334 appendectomy cases (76 simple and 258 non-simple cases) for acute appendicitis. These cases were divided into training (n = 106) and test cohorts (n = 228). A radiomics model was developed using the radiomic features of the appendix area on CT images as the input variables. A CT model was developed using the clinical and CT features as the input variables. A combined model was developed by combining the radiomics model and clinical information. These models were tested, and their performance was evaluated by receiver operating characteristic curves and decision curve analysis (DCA). The variables independently associated with non-simple appendicitis in the combined model were body temperature, age, percentage of neutrophils and Rad-score. The AUC of the combined model was significantly higher than that of the CT model (P = 0.041). The AUC of the radiomics model was also higher than that of the CT model but did not reach a level of statistical significance (P = 0.053). DCA showed that all three models had a higher net benefit (NB) than the default strategies, and the combined model presented the highest NB. A nomogram of the combined model was developed as the graphical representation of the final model. It is feasible to use the combined information of clinical and CT radiomics models for the differentiation of simple and non-simple acute appendicitis.

Validation of scoring systems for the prediction of complicated appendicitis in adults using clinical and computed tomographic findings. Insights Imaging 2023; 14:191. [PMID: 37973644 PMCID: PMC10654319 DOI: 10.1186/s13244-023-01540-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 10/15/2023] [Indexed: 11/19/2023] Open
Abstract
OBJECTIVES The study aimed to evaluate scoring systems for predicting complicated appendicitis in adults diagnosed with acute appendicitis on computed tomography. METHODS Three hundred twenty-five consecutive adult patients (mean age 51.9 ± 19.6 years, 212 women) diagnosed with acute appendicitis on computed tomography were retrospectively included. Clinical and imaging findings were compared between patients with and without complicated appendicitis, and independent associations were identified. As C-reactive protein was not available for most patients, 5 out of 8 scoring systems were modified. They, and a newly proposed system, were compared via area under the receiver operating characteristics (ROC) curve (AUC), Additionally, the latter was internally validated. Pairwise comparison was performed, and diagnostic performance of these scoring systems was obtained. RESULTS One hundred twenty-seven patients (36.8%) had complicated appendicitis. Significant independent associations were found between complicated appendicitis and duration of symptoms > 12 h, appendicolith, periappendiceal fat stranding, periappendiceal fluid, and extraluminal air (p values < 0.001 to 0.037; AUCs of 0.824-0.829). AUCs of 9 scoring systems ranged from 0.692 to 0.831. Of these, modified Atema, Kim HY, and proposed scores had similarly high and non-significantly different AUCs (0.793-0.831) on pairwise comparison. Their sensitivities, specificities, and accuracies were 73.0-90.6%, 48.5-70.6%, and 64.3-72.3%, respectively. Internal validity test demonstrated high AUCs (0.826-0.844) with one of the proposed scores using odds ratio having 100% sensitivity and 100% negative predictive value. CONCLUSIONS Few scoring systems, including proposed ones, had high AUCs, sensitivity, and reasonable specificities, which could potentially aid in safely selecting adult patients with acute appendicitis for nonoperative management. CRITICAL RELEVANCE STATEMENT The study suggests few scoring systems for predicting complicated appendicitis with high AUCs and reasonable sensitivities, potentially aiding in selecting patients for nonoperative management. KEY POINTS • The study evaluated existing and proposed new scoring systems to predict complicated appendicitis in adults with acute appendicitis on computed tomography. • Several factors were found to be significantly associated with complicated appendicitis, including duration of symptoms, appendicolith, periappendiceal fat stranding, periappendiceal fluid, and extraluminal air. • The modified Atema, Kim HY, and newly proposed scoring systems performed well, potentially aiding in nonoperative management selection.

Abstract
INTRODUCTION Appendicolithiasis is a risk factor for perforated acute appendicitis. There is limited inpatient data on predictors of progression in appendicolithiasis-associated non-perforated acute appendicitis. METHODS We identified adults presenting with appendicolithiasis-associated non-perforated acute appendicitis (on computed tomography) who underwent appendectomy. Logistic regression was used to investigate predictors of in-hospital perforation (on histopathology). RESULTS 296 patients with appendicolithiasis-associated non-perforated acute appendicitis were identified; 48 (16.2%) had perforation on histopathology. Mean (standard deviation [SD]) age was 39 (14.9) years. The mean (SD) length of stay (LOS) was 1.5 (1.8) days. LOS was significantly longer with perforated (mean [SD]: 3.0 [3.1] days) vs. non-perforated (mean [SD]: 1.2 [1.2] days) appendicitis (p < 0.001). On multivariate analysis, in-hospital perforation was associated with age > 65 years (OR 5.4, 95% CI: 1.4- 22.2; p = 0.015), BMI > 30 kg/m2 (OR 3.5, 95% CI: 1.3-8.9; p = 0.011), hyponatremia (OR 3.6, 95% CI: 1.3-9.8; p = 0.012). There was no significant association with age 25-65 years, gender, race, steroids, time-to- surgery, neutrophil percentage, or leukocyte count. CONCLUSION Geriatric age, obesity, and hyponatremia are associated with progression to perforation in appendicolithiasis-associated non-perforated acute appendicitis.

Usefulness of serum sodium levels as a novel marker for predicting acute appendicitis severity: a retrospective cohort study. BMC Surg 2023; 23:312. [PMID: 37838701 PMCID: PMC10576296 DOI: 10.1186/s12893-023-02224-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Accepted: 10/07/2023] [Indexed: 10/16/2023] Open
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 is one of the most common surgical causes of acute abdominal pain in adults and children in the emergency department. It is treated by appendectomy by either an open or laparoscopic approach. Although laparoscopic appendectomy has been used for the last 35 years, there are still indications for an open approach in some cases. OBJECTIVES The aim of this study was to explore the awareness of the general population in Saudi Arabia of appendectomy according to the surgical approach. METHODS A cross-sectional survey using a questionnaire constructed by an expert based on Google Forms (Google, Mountain View, CA) was used from February to March 2022. Variables were demographical data, general knowledge, history of appendectomy, its surgical approach, and postoperative complications, if any. RESULTS The study included 162 participants. The awareness level of acute appendicitis was high (72.2%). History of appendectomy was almost 30% and was significantly more common in males than females (p = 0.045). The rate of postoperative complications showed a significant difference between open (4.3%) vs. laparoscopic approaches (8%) (p = 0.001). CONCLUSION Young, educated Saudis are aware of the importance of surgical intervention for acute appendicitis. However, further hospital-based studies are recommended concerning the role of the surgical approach and its various impacts on postoperative complications.

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
INTRODUCTION Same-day discharge (SDD) after laparoscopic appendectomy for acute nonperforated appendicitis is safe, without an increased rate of postoperative complications, emergency department visits, or readmissions. We aimed to evaluate caregiver satisfaction with this protocol. METHODS Patients discharged on the day of laparoscopic appendectomy for nonperforated acute appendicitis were identified between January 2022 and August 2022. Surveys to evaluate satisfaction with the protocol were distributed to the caregivers via email or text message 96 h after discharge. Telephone surveys were conducted if there were no responses to the initial online survey. The surveys assessed comfort with SDD, postoperative pain control adequacy, postoperative provider contact, and overall satisfaction. The protocol focused on avoidance of narcotics in the postoperative period and immediate return to a regular diet. RESULTS A total of 255 cases of nonperforated acute appendicitis underwent SDD. The survey response rate was 50.6% (n = 129). Most respondents were Caucasian (69.0%, n = 89) and male (51.9%, n = 67) with a median age of 12.0 y (IQR 8.9,14.7). The median postoperative length of hospital stay was 3.8 h (interquartile range [IQR] 3.2,4.8). The overall satisfaction rate was 91.5%, with 118 caregivers feeling satisfied with SDD. Most caregivers felt comfortable with the SDD protocol (89.9%, n = 116), with 22.5% (n = 29) calling a medical provider postoperatively. Approximately nine out of 10 caregivers reported that pain was adequately controlled (91.5%, n = 118). In contrast, those that were dissatisfied reported issues with pain control and anxiety with SDD after a surgical procedure. CONCLUSIONS Caregiver satisfaction and comfort with same-day discharge following laparoscopic appendectomy is high with appropriate anticipatory guidance and preoperative education.

Abstract
PURPOSE To investigate the relationship of IgE-mediated allergy and complicated appendicitis (CA) and overall prognosis. METHODS We retrospectively analyzed a consecutive series of patients with acute appendicitis (AA) who received appendectomy at Beijing Children's Hospital between July 1, 2018 and June 30, 2020. Patients were classified into two groups, with or without IgE-mediated allergies. Logistic regression adjusting for age, duration of symptoms, WBC count, neutrophil count, C-reactive protein (CRP), Appendicolith and presence of allergy was used to evaluate the association between CA and IgE-mediated allergy. RESULTS In total, 1156 patients were included. 162 (14.0%) of the patients had IgE-mediated allergy while 994 (86.0%) did not. Children with allergies had a decreased chance of developing CA after adjustment for age, duration of symptoms, WBC count, Neutrophil count, CRP, and appendicolith present rate (adjusted OR = 0.582, 0.364-0.929, P = 0.023). There were no significant differences in operative time, length of hospital stay (LOS), readmission, or adhesive intestinal obstruction rate between allergy and non-allergy patients. CONCLUSIONS IgE-mediated allergy is related to a reduction risk of CA in the pediatric population and may not affect the prognosis of patients received appendectomy.

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
Introduction Low accuracy of clinical variables can result in delayed diagnosis and increase the incidence of complicated appendicitis in some cases. This study aimed to determine the value of simple complete blood count (CBC) biomarkers in predicting complicated appendicitis. Methods This is a single-center retrospective cross-sectional study, which was conducted on cases referred to emergency department following acute appendicitis who underwent appendectomy, to evaluate the accuracy of some cell blood count variables (white blood cell count (WBC), neutrophil percent, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV)) in predicting complicated cases (gangrenous and ruptured appendicitis). Results There were 252 (68.3%) patients in the uncomplicated appendicitis group and 117 (31.7%) patients in the complicated appendicitis group. The mean age of patients was 34.1 ± 1.09 (Range: 18 -79) years (55.3% male). There were no differences between groups regarding the mean age (p = 0.053), gender distribution (p=0.07), Alvarado score (p = 0.055), platelet count (p =0.204), PLR (p = 0.115), and MPV (p = 0.205). The complicated appendicitis cases had longer onset of symptoms (p <0.001), higher WBC count (p = 0.011), higher neutrophil count (p < 0.001), and higher NLR (p < 0.001). Neutrophil count (area under the curve (AUC) = 0.61, 95% confidence interval (CI) = 0.56-0.66; p = 0.001) and NLR (AUC = 0.65, 95% CI = 0.60-0.69; p = 0.001) had higher level of accuracy in this regard. In contrast, the area under the curve of WBC count (AUC = 0.57, 95% CI = 0.52-0.63; p = 0.22), platelet count (AUC = 0.44, 95% CI = 0.38-0.49; p = 0.049), PLR (AUC = 0.57, 95% CI = 0.52-0.62; p = 0.026), and MPV (AUC = 0.54, 95% CI = 0.49-0.60; p = 0.193) showed low accuracy in predicting complicated acute appendicitis. Conclusion Based on the findings of present study it seems that WBC, neutrophil percent, NLR, PLR, and MPV have failed to poor accuracy in predicting cases with complicated appendicitis in emergency department.

Abstract
BACKGROUND Acute appendicitis is a common surgical emergency worldwide, yet data specific to Central America, including Honduras, are limited. This study aimed to investigate the epidemiological, clinical, surgical, and post-surgical characteristics of acute appendicitis in a Honduran general hospital. METHODS A descriptive, quantitative, non-experimental, cross-sectional study was conducted at the Mario Catarino Rivas Hospital in San Pedro Sula, Honduras. The study sample consisted of 100 patients admitted with acute appendicitis from January to April 2022. Data on demographic factors, surgical interventions, appendicitis phases, appendix location, and laboratory findings were collected and analyzed. RESULTS The mean age of the participants was 28.5 years, with a slight male predominance (52%). Timely surgical intervention was performed in 95% of cases within the first 12 hours. The gangrenous phase was observed in 30% of patients, followed by the perforated (24%), edematous (24%), and suppurative (22%). Retrocecal appendicitis accounted for the majority of cases (66%). Moderate leucocytosis (46%) and severe leucocytosis (39%) were associated with acute appendicitis severity. A higher neutrophil percentage was indicative of complicated appendicitis. Computed tomography was underutilized, with only one patient undergoing the examination. CONCLUSION This study provides valuable insights into Honduras' epidemiological, clinical, and surgical characteristics of acute appendicitis. Early surgical intervention and laboratory findings, such as leukocyte count and neutrophil percentage, can aid in assessing disease severity. Further research is warranted to understand the unique aspects of acute appendicitis in Central America and optimize patient management. This study highlights the need for multi-centre studies and long-term follow-up to enhance our understanding of appendicitis in similar populations.

Abstract
Adults can accidentally swallow foreign bodies (FBs) with food. In rare occasions, these can lodge in the appendix lumen causing inflammation. This is known as foreign body appendicitis. We conducted this study to review different types and management of appendiceal FBs. A comprehensive search on PubMed, MEDLINE, Embase, Cochrane Library and Google Scholar was performed to detect appropriate case reports for this review. Case reports eligible for this review included patients above 18 years of age with all types of FB ingestion causing appendicitis. A total of 64 case reports were deemed to be eligible for inclusion in this systematic review. The patient mean age was 44.3 ± 16.7 years (range, 18-77). Twenty-four foreign bodies were identified in the adult appendix. They were mainly lead shot pellet, fishbone, dental crown or filling, toothpick, and others. Forty-two percent of the included patients presented with classic appendicitis pain, while 17% were asymptomatic. Moreover, the appendix was perforated in 11 patients. Regarding modalities used for diagnosis, computed tomography (CT) scans confirmed the presence of FBs in 59% of cases while X-ray only managed to detect 30%. Almost all of the cases (91%) were treated surgically with appendicectomy and only six were managed conservatively. Overall, lead shot pellets were the most common foreign body found. Fishbone and toothpick accounted for most of the perforated appendix cases. This study concludes that prophylactic appendicectomy is recommended for the management of foreign bodies detected in the appendix, even if the patient is asymptomatic.

Abstract
Appendicitis, an acute inflammation of the appendix, affects all demographic groups and exhibits various incidences and clinical manifestations. While acute appendicitis typically presents with colicky periumbilical abdominal pain that localizes to the right lower quadrant, atypical presentations are more common in children, geriatric, and pregnant patient populations, leading to delays in diagnosis. Clinical evaluation, clinical scoring systems, and inflammatory markers are commonly used, but their limitations have led to the increased use of diagnostic imaging in patients suspected of appendicitis. Acute appendicitis is managed by non-operative and operative management, depending on whether it is uncomplicated or complicated. Developing diagnostic pathways to improve outcomes and reduce complications is crucial. Although medical advancements have been made, diagnosing and managing appendicitis can be challenging, mainly when patients are present atypically. This literature review aims to comprehensively review typical and atypical presentations of appendicitis and their current implications for diagnosis and treatment modalities in pediatric, adult, pregnant, and geriatric patient populations.

Abstract
INTRODUCTION Acute appendicitis is the most common non-traumatic surgical emergency and early diagnosis and management are crucial to decrease morbidity and mortality. There is a variety of scoring systems and radiological investigations that have been used in the diagnosis of acute appendicitis. Hence, the aim of this study is to assess the diagnostic approach in patients with suspected appendicitis in a tertiary care hospital, focusing on the radiological burden. METHODS This is a cross-sectional study reviewing the electronic and manual medical records of all adult patients admitted with the diagnosis of acute appendicitis between January 2018 and December 2018 in Salmaniya Medical Complex, Manama, Bahrain. A review of the method of diagnosis (clinical, ultrasound, computed tomography, or others) was done, with a comparison to histopathological results in those that underwent surgical intervention to determine sensitivity and specificity. RESULTS In the study period, 488 patients were admitted with acute appendicitis; out of these, 461 underwent surgical intervention. A total of 66 CT scans and 148 ultrasounds were conducted for these patients, out of which 57% of ultrasounds and 86% of CT scans accurately diagnosed acute appendicitis based on histopathological diagnosis, resulting in a sensitivity of 65% and 92%, respectively, and a specificity of 56% and 25%, respectively. CONCLUSION The most accurate method of diagnosis of acute appendicitis (highest sensitivity) is CT scanning. However, a prospective study with a detailed assessment of complications of appendicitis is recommended.

Abstract
Background: It is recognized increasingly that common surgical infections of the peritoneal cavity may be treated with antibiotic agents alone, or source control surgery with short-course antimicrobial therapy. By extension, testable hypotheses have emerged that such infections may not actually be infectious diseases, but rather represent inflammation that can be treated successfully with neither surgery nor antibiotic agents. The aim of this review is to examine extant data to determine which of uncomplicated acute appendicitis (uAA), uncomplicated acute calculous cholecystitis (uACC), or uncomplicated mild acute diverticulitis (umAD) might be amenable to management using supportive therapy alone, consistent with the principles of antimicrobial stewardship. Methods: Review of pertinent English-language literature and expert opinion. Results: Only two small trials have examined whether uAA can be managed with observation and supportive therapy alone, one of which is underpowered and was stopped prematurely because of challenging patient recruitment. Data are insufficient to determine the safety and efficacy of non-antibiotic therapy of uAA. Uncomplicated acute calculous cholecystitis is not primarily an infectious disease; infection is a secondary phenomenon. Even when bactibilia is present, there is no high-quality evidence to suggest that mild disease should be treated with antibiotic agents. There is evidence to indicate that antibiotic prophylaxis is indicated for urgent/emergency cholecystectomy for uACC, but not in the post-operative period. Uncomplicated mild acute diverticulitis, generally Hinchey 1a or 1b in current nomenclature, does not benefit from antimicrobial agents based on multiple clinical studies. The implication is that umAD is inflammatory and not an infectious disease. Non-antimicrobial management is reasonable. Conclusions: Among the considered disease entities, the evidence is strongest that umAD is not an infectious disease and can be treated without antibiotic agents, intermediate regarding uACC, and lacking for uAA. A plausible hypothesis is that these inflammatory conditions are related to disruption of the normal microbiome, resulting in dysbiosis, which is defined as an imbalance of the natural microflora, especially of the gut, that is believed to contribute to a range of conditions of ill health. As for restorative pre- or probiotic therapy to reconstitute the microbiome, no recommendation can be made in terms of treatment, but it is not recommended for prevention of primary or recurrent disease.

Abstract
BACKGROUND Acute appendicitis is one of many common reasons for acute abdominal pain, and its exact diagnosis is still debatable amongst clinicians. This systematic review and meta-analysis of diagnostic test accuracy aim to look at serum pentraxin-3 performance in diagnosing acute appendicitis in patients with acute abdominal pain. METHODS This systematic review is registered on the International Prospective Register of Systematic Reviews (CRD42022338296). The primary outcome of this study is to examine the sensitivity, specificity, and post-test probability of serum pentraxin-3 (the index test) in patients with acute appendicitis. We searched various academic databases such as Pubmed, MEDLINE, Cochrane Library, Science Direct, Google Scholar, ScieLO, MedRxiv, BioRxiv, and Research Square. Two independent authors reviewed, selected the articles, and extracted the data. The analysis was done using STATA software using the "midas" and "metandi" commands. RESULTS Five articles fulfilled our inclusion criteria with 520 patients, and 27.5% of them were children. The combined sensitivity is 90.3% (95% confidence interval 78.6-95.9), and the combined specificity is 91.2% (95% confidence interval 22.1-99.7). The area under the curve is 0.94 (95% confidence interval 0.92-0.96). Fagan's Nomogram showed that the positive likelihood ratio is 10.38 (95% confidence interval 0.38-284.76) with an 87% post-test probability, while the negative likelihood ratio is 0.11 (95% confidence interval 0.04-0.27) with a 7% post-test probability. The combined negative predictive value is 0.89 (95% confidence interval 0.81-0.98), and the positive predictive value is 0.90 (95% confidence interval 0.81-0.98). CONCLUSION Serum pentraxin-3 could only be used as a confirmation test for acute appendicitis but not exclude it.

Abstract
BACKGROUND Appendicitis is one of the most common surgical emergencies globally and it can both be difficult to diagnose but also to differentiate complicated from uncomplicated appendicitis preoperatively. The objective of this scoping review was to develop an overview of biomarkers in blood discriminating complicated from uncomplicated appendicitis and characterize their applicability in an acute setting including time, cost, and analysis technique required as well as their individual precision. METHOD This scoping review was reported in accordance with PRISMA-ScR. The included studies had to report on biomarkers measured in the blood for at least ten patients with suspected appendicitis. A systematic literature search was conducted on August 28, 2022, in PubMed and Embase but restricted to articles published in January 2000 and onwards. A protocol was uploaded to Open Science Framework prior to data extraction. RESULTS A total of 65 biomarkers were included from 52 studies, covering 14,312 patients. There was 60% routine- and 40% novel biomarkers based on the reported analysis technique. The most frequently investigated biomarkers within each group were white blood cell count and procalcitonin. The routine biomarkers were of low financial cost but poor diagnostic accuracy with sensitivity ranging between 15 and 100% and specificity between 27 and 100%. Novel markers were costly ranging from 275 to 800$, and their diagnostic accuracy was based on limited population sizes (median 34 patients) and reported for only 5% of the novel markers. CONCLUSION Routine biomarkers were applicable in an acute setting but had poor diagnostic accuracy. Novel biomarkers are being investigated for potential, but the concept is still premature due to lack of diagnostic accuracy studies reporting cost-benefit for individual markers and whether they can be applied in an acute setting.

Abstract
BACKGROUND AND AIMS Microscopic colitis (MC) is an inflammatory bowel disease and a common cause of chronic diarrhea. Appendectomy has been suggested to have immunomodulating effects in the colon, influencing the risk of gastrointestinal disease. The relationship between appendectomy and MC has only been sparsely studied. METHODS This was a case-control study based on the nationwide ESPRESSO (Epidemiology Strengthened by histoPathology Reports in Sweden) cohort, consisting of histopathological examinations in Sweden, linked to national registers. Patients with MC were matched to population controls by age, sex, calendar year of biopsy, and county of residence. Data on antecedent appendectomy and comorbidities were retrieved from the Patient Register. Unconditional logistic regression models were conducted presenting odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for country of birth and matching factors. Further subanalyses were made based on MC subtypes (lymphocytic colitis and collagenous colitis), follow-up time postappendectomy and severity of appendicitis. RESULTS The study included 14,520 cases of MC and 69,491 controls, among these 7.6% (n = 1103) and 5.1% (n = 3510), respectively, had a previous appendectomy ≥1 year prior to MC or matching date. Patients with a previous appendectomy had an increased risk of MC in total (OR, 1.50; 95% CI, 1.40-1.61) and per the collagenous colitis subtype (OR, 1.67; 95% CI, 1.48-1.88) or lymphocytic colitis subtype (OR, 1.42; 95% CI, 1.30-1.55). The risk remained elevated throughout follow-up, and the highest risk was observed in noncomplicated appendicitis. CONCLUSIONS This nationwide case-control study found a modestly increased risk of developing MC following appendectomy.

Abstract
Acute bowel diseases are responsible for more than one third of subjects who were referred to the emergency department for acute abdominal pain and gastrointestinal evaluation. Gastrointestinal ultrasound (GIUS) is often employed as the first imaging method, with a good diagnostic accuracy in the setting of acute abdomen, and it can be an optimal diagnostic strategy in young females due to the radiation exposure related to X-ray and computed tomography methods. The physician can examine the gastrointestinal system in the area with the greatest tenderness by ultrasound, thus obtaining more information and data on the pathology than the standard physical examination. In this comprehensive review, we have reported the most relevant indications and advantages to using ultrasound in the investigation of abdominal acute pain.

Abstract
Introduction Appendicitis is a common cause for emergency operations in the western part of the world, mostly affecting children and young adults. Ultrasound in well-trained hands is an effective imaging tool in making this diagnosis; however, this does not come without its challenges and potential complications. Case report This is a case of a 19-year-old male with one-day history of severe pain in the right iliac fossa; blood results showed raised inflammatory markers. Ultrasound revealed a large abnormal loop of bowel containing heterogeneously echogenic contents, and two large appendicoliths at the base and fundus, with the presence of free fluid in the right iliac fossa and oedema in the adjacent mesentery. Laparoscopic appendectomy confirmed the presence of severe appendicitis with generalised peritonitis and appendicolith. Histology revealed gangrenous appendicitis with perforation in two places. Discussion This case demonstrates that making a diagnosis of an inflamed appendix alone on ultrasound is not enough, and conducting a detailed assessment of the inflamed appendix and its surrounding anatomy is essential so that all the associated findings can be reported to aid in the patient management, reduce hospital stay and improve overall diagnosis and prognosis.

The Diagnostic Differentiation Challenge in Acute Appendicitis: How to Distinguish between Uncomplicated and Complicated Appendicitis in Adults. Diagnostics (Basel) 2022; 12:diagnostics12071724. [PMID: 35885627 PMCID: PMC9322371 DOI: 10.3390/diagnostics12071724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/07/2022] [Accepted: 07/12/2022] [Indexed: 11/24/2022] Open
Abstract
(1) Background: How to best define, diagnose and differentiate uncomplicated from complicated acute appendicitis remains debated. Hence, the aim of this review was to present an overview of the current knowledge and emerging field of acute appendicitis with a focus on the diagnostic differentiation of severity currently subject to ongoing investigations. (2) Methods: We conducted a PubMed search using the MeSH terms “appendicitis AND severity” and “appendicitis AND classification”, with a focus on studies calling appendicitis as ‘uncomplicated’ or ‘complicated’. An emphasis on the last 5 years was stressed, with further studies selected for their contribution to the theme. Further studies were retrieved from identified full-text articles and included per the authors’ discretion. (3) Results: The assumption that appendicitis invariably will proceed to perforation has been outdated. Both uncomplicated and complicated appendicitis exist with likely different pathophysiology. Hence, this makes it important to differentiate disease severity. Clinicians must diagnose appendicitis, but, in the next step, also differentiate between uncomplicated and complicated appendicitis in order to allow for management decisions. Diagnostic accuracy without supportive imaging is around 75–80% and, based on clinical judgement and blood tests alone, the negative appendectomy rate has been described as high as 36%. More research is needed on available biomarkers, and the routine use of imaging still remains debated. Scoring systems have the potential to improve diagnostic accuracy, but no scoring system has yet been validated for differentiating disease severity. Currently, no universally agreed definition exists on what constitutes a complicated appendicitis. (4) Conclusions: Uncomplicated and complicated appendicitis appear to have different pathophysiology and should be treated differently. The differentiation between uncomplicated and complicated appendicitis remains a diagnostic challenge.

Abstract
BACKGROUND: Acute appendicitis is the most common emergency surgical case, leading to further complications if not treated immediately. Limited diagnostics infrastructure is an obstacle in developing countries, especially in the regions. Therefore, alternatives such as clinical scoring systems are required to assist in diagnosis.
AIM: This study aimed to compare the use of the RIPASA and Labeda scores to assess the severity of acute appendicitis morphology by determining the accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and negative appendectomy rate.
METHODS: This was a cross-sectional study designed to assess the severity of morphology of intra-operative acute appendicitis in Dr. Chasan Boesoirie Hospital and network hospitals in Ternate, North Maluku, Indonesia. Data regarding patient characteristics, leukocytes, and acute appendicitis severity were collected and analyzed alongside RIPASA and Labeda scores using the Chi-square test. p < 0.05 were considered statistically significant.
RESULTS: Of 59 cases, 39 (66.1%) were complicated acute appendicitis and 20 (33.9%) were noncomplicated acute appendicitis. Chi-square test results showed that there was a significant relationship (p ≤ 0.001) between RIPASA/Labeda scores and the severity of acute appendicitis morphology.
CONCLUSION: RIPASA and Labeda scores had the same accuracy, sensitivity, specificity, positive predictive value, and negative predictive value for acute appendicitis severity. Thus, RIPASA and Labeda scores can be used by physicians to help establish a diagnosis of acute appendicitis and determine the need for emergency surgery, as well as predict the possibility of morbidity/complications in patients.

[PMID: 35289145 PMCID: PMC9081692 DOI: 10.3348/kjr.2021.0596] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Revised: 10/18/2021] [Accepted: 11/21/2021] [Indexed: 11/15/2022] Open
Abstract
Due to its excellent diagnostic performance, CT is the mainstay of diagnostic test in adults with suspected acute appendicitis in many countries. Although debatable, extensive epidemiological studies have suggested that CT radiation is carcinogenic, at least in children and adolescents. Setting aside the debate over the carcinogenic risk of CT radiation, the value of judicious use of CT radiation cannot be overstated for the diagnosis of appendicitis, considering that appendicitis is a very common disease, and that the vast majority of patients with suspected acute appendicitis are adolescents and young adults with average life expectancies. Given the accumulated evidence justifying the use of low-dose CT (LDCT) of only 2 mSv, there is no reasonable basis to insist on using radiation dose of multi-purpose abdominal CT for the diagnosis of appendicitis, particularly in adolescents and young adults. Published data strongly suggest that LDCT is comparable to conventional dose CT in terms of clinical outcomes and diagnostic performance. In this narrative review, we will discuss such evidence for reducing CT radiation in adolescents and young adults with suspected appendicitis.

Abstract
BACKGROUND Non-operative management of uncomplicated acute appendicitis is an option, but omission of antibiotics from the regimen has not been tested. METHODS A double-blind, placebo-controlled, superiority RCT in adults with CT-confirmed uncomplicated acute appendicitis was designed to compare placebo with antibiotics (intravenous ertapenem followed by oral levofloxacin and metronidazole). The primary endpoint was treatment success (resolution resulting in discharge without appendicectomy within 10 days); secondary outcomes included pain scores, complications, hospital stay, and return to work. RESULTS From May 2017 to September 2020, 72 patients with a mean(s.d.) age of 37.5 (11.1) years were recruited at five hospitals. Six were excluded after randomization (5 early consent withdrawals, 1 randomization protocol violation), 35 were assigned to receive antibiotics, and 31 to receive placebo. Enrolment challenges (including hospital pharmacy resources in an acute-care surgery setting) meant that only the lowest sample size of three predefined scenarios was achieved. The 10-day treatment success rate was 87 (95 per cent c.i. 75 to 99) per cent for placebo and 97 (92 to 100) per cent for antibiotics. This clinical difference of 10 (90 per cent c.i. -0.9 to 21) per cent was not statistically different for the primary outcome (1-sided P = 0.142), and secondary outcomes were similar. CONCLUSION The lack of antibiotic superiority statistically suggests that a non-inferiority trial against placebo is warranted in adults with CT-confirmed mild appendicitis.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic had a striking impact on healthcare services in the world. The present study aimed to investigate the impact of the COVID-19 pandemic on the presentation management and outcomes of acute appendicitis (AA) in different centers in the Middle East. METHODS This multicenter cohort study compared the presentation and outcomes of patients with AA who presented during the COVID-19 pandemic in comparison to patients who presented before the onset of the pandemic. Demographic data, clinical presentation, management strategy, and outcomes were prospectively collected and compared. RESULTS Seven hundred seventy-one patients presented with AA during the COVID pandemic versus 1174 in the pre-COVID period. Delayed and complex presentation of AA was significantly more observed during the pandemic period. Seventy-six percent of patients underwent CT scanning to confirm the diagnosis of AA during the pandemic period, compared to 62.7% in the pre-COVID period. Non-operative management (NOM) was more frequently employed in the pandemic period. Postoperative complications were higher amid the pandemic as compared to before its onset. Reoperation and readmission rates were significantly higher in the COVID period, whereas the negative appendicectomy rate was significantly lower in the pandemic period (p = 0.0001). CONCLUSION During the COVID-19 pandemic, a remarkable decrease in the number of patients with AA was seen along with a higher incidence of complex AA, greater use of CT scanning, and more application of NOM. The rates of postoperative complications, reoperation, and readmission were significantly higher during the COVID period.

Open Access Emerg Med 2021; 13:265-271. [PMID: 34188562 PMCID: PMC8235934 DOI: 10.2147/oaem.s315228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 05/25/2021] [Indexed: 11/23/2022] Open
Abstract
Background Acute appendicitis is the most common cause of acute abdomen surgery. Despite its commonness and the abundance of literature on the subject, its diagnosis remains challenging. Delay in intervention results in complications of the process leading to increased morbidity and mortality. Methodology An observational prospective cohort study was conducted, and all patients who had undergone appendectomy for a clinical diagnosis of appendicitis were included in the study. Data were analysed using Statistical Package for Social Sciences (SPSS) version 23. Results Half of the study participants were in the age range of 18–25 years with male preponderance (63.9%). The mean duration of symptoms was 51.3 hours. The most common presenting symptom was abdominal pain (98.2%), while right lower quadrant tenderness was the most common sign (93.4%). Abdominal ultrasound was done in 81% of the study population with a sensitivity and specificity of 95.7% and 33.3%, respectively. Three-quarters (74.4%) of the patients had uncomplicated appendicitis, while 1.8% had a grossly normal appendix. None of the appendectomy specimens were sent for pathology. The mean hospital stay was 3.2 days. The morbidity and mortality rate were 3.8% and 0.4%, respectively. Conclusion Acute appendicitis was the most common emergency surgical procedure in the study period. Abdominal ultrasound was used in the majority of the patients as supplementary imaging for the diagnosis of acute appendicitis. Uncomplicated appendicitis took the major share of the intraoperative finding leading to acceptable morbidity and mortality rates.
