RESUMO
INTRODUCTION: Pediatric surgical care is becoming increasingly regionalized, often resulting in limited access. Interfacility transfers pose a significant financial and emotional burden to when they are potentially avoidable. Of transferred patients, we sought to identify clinical factors associated with avoidable transfers in pediatric patients with suspected appendicitis. METHODS: We performed a single-center retrospective study at an academic tertiary referral children's hospital in an urban setting. We included children who underwent interfacility transfer to our center with a transfer diagnosis of appendicitis from July 1, 2021 to June 30, 2023. Encounters were designated as either an appropriate transfer (underwent appendectomy) or an avoidable transfer (did not undergo appendectomy). Encounters treated nonoperatively for complicated appendicitis were excluded. Bivariate analysis was performed using Mann-Whitney test and chi-square tests. RESULTS: A total of 444 patients were included: 71.2% were classified as appropriate transfers and 28.8% as avoidable transfers. Patients with avoidable transfer were younger compared to those in the appropriate transfer cohort (median age 9 y, interquartile range: 7-13 versus 11 y, interquartile range: 8-14; P < 0.001). Avoidable transfers less frequently presented with the typical symptoms of fever, migratory abdominal pain, anorexia, and nausea/emesis (P = 0.005). Avoidable transfers also reported shorter symptom duration (P = 0.040) with lower median white blood cell count (P < 0.001), neutrophil percentage (P < 0.001), and C-reactive protein levels (P < 0.003). Avoidable transfers more frequently underwent repeat imaging upon arrival (42.9% versus 12.7%, P < 0.001). CONCLUSIONS: These findings highlight the importance of clinical history in children with suspected appendicitis. Younger patients without typical symptoms of appendicitis, those with a shorter duration of symptoms, and lower serum inflammatory markers may benefit from close observation without transfer.

INTRODUCTION: Reliance on International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes may misclassify perforated appendicitis with resultant research, fiscal, and public health implications. We aimed to improve the accuracy of administrative data for perforated appendicitis classification relying on ICD-10-CM codes from 2015 to 2018. METHODS: We conducted a retrospective study of randomly sampled patients aged ≤18 years diagnosed with acute appendicitis from eight children's hospitals. Patients were identified using the Pediatric Health Information System, and true perforation status was determined by medical record review. We developed two algorithms by leveraging Pediatric Health Information System data elements and data mining (DM) approaches. The two developed algorithm performance was compared against algorithms that exclusively relied on ICD-10-CM codes using area under the curve and other measures. RESULTS: Of 1051 clinically validated encounters that were included, 383 (36.4%) patients were identified to have perforated appendicitis. The two algorithms developed using DM approaches primarily leveraged ICD-10-CM codes and length of stay. DM-developed algorithms had a significantly higher accuracy than algorithms relying exclusively on ICD-10-CM (P value < 0.01): sensitivity and specificity for DM-developed algorithms were 0.86-0.88 and 0.95-0.97, respectively, which were overall higher than algorithms that relied on only ICD-10-CM. CONCLUSIONS: This study provides an algorithm that can improve the accuracy of perforated appendicitis classification using commonly available elements in administrative data. We recommend that this algorithm is used in future appendicitis classification to ensure valid reporting, hospital-level benchmarking, and fiscal or public health assessments.

BACKGROUND: Appendicitis in pancreatic transplant recipients can be challenging to diagnose and manage. Incidental appendicectomy (IA) during pancreas transplantation obviates the risk of appendicitis but potentially at the cost of increased operating time or early post-operative complications. This study reviewed the value of IA at a single center. METHODS: This was a retrospective study of patients who underwent a pancreas transplant in our unit from January 1st, 2012 to December 31st, 2020, with end of follow-up on May 21st, 2023; recipients were grouped by whether or not an IA was performed during pancreas transplantation. Donor, recipient, operative, and graft outcomes were compared between the two groups. Post-transplant complications related to appendiceal pathology (or IA) were recorded and classified. RESULTS: Two hundred forty-three patients underwent a pancreas transplant; 227 (93%) patients had an appendix in situ at transplantation, and of these 53 (23%) underwent an IA and 174 (77%) did not. There were no statistically significant differences in operative time (p = .06) or hospital stay (p = .50) between the two groups. In the IA cohort, there were no Clavien-Dindo Grade III-V complications relating to the appendicectomy. In those that did not undergo an IA, two patients (1%) subsequently required appendicectomy due to appendicitis. Comparison of pancreatic graft survival showed no statistically significant difference between the groups (p = .44). CONCLUSIONS: This study suggests that IA is effective at reducing risks of post-transplant appendiceal complications without significantly prolonging inpatient stay or impairing graft survival. These data support the consideration of undertaking an IA for all patients undergoing a pancreas transplant.

Acute appendicitis (AA) in pediatric patients with acute leukemia mandates prompt treatment. Diagnosis presents challenges, relying on clinical and radiological assessments, often leading to treatment delays that may disrupt leukemia management. Our study on 14 such cases underscores the pivotal role of swift intervention. While conservative AA treatment may pose no risk to healthy children, our findings mandate the performance of laparoscopic appendectomy within 24 hours of diagnosis. This strategy yielded successful surgical outcomes while ensuring uninterrupted leukemia care. Our experience contributes important insights to the limited understanding of navigating this complex clinical scenario.

BACKGROUND: Acute appendicitis (AA) is one of the most common reasons for visiting the emergency room. The lack of proper diagnosis and rapid treatment of AA may lead to severe complications such as intestinal perforation and increased mortality. This study aimed to evaluate the diagnostic accuracy of the Alvarado criteria, ultrasound, and CRP criteria in comparison with their combined use in patients with suspected AA who presented to the emergency room. METHODS: In this diagnostic accuracy study, 1411 patients with suspected AA who presented to the emergency department of Firoozabadi Hospital affiliated with Iran University of Medical Sciences and underwent appendectomy from October 2019 to October 2021 were examined. Nine hundred eighty-eight patients were enrolled. All patients were assessed using Alvarado, CRP, and ultrasound. The definitive diagnosis of AA was based on pathological findings and was considered the gold standard. Statistical analyses were performed with STATA VER 11.5. The diagnostic accuracy for each group was compared using the Pearson chi-square test. A value of p < 0.05 was considered statistically significant. RESULTS: The mean age was 29.57 ± 13.66 years. The sensitivity and specificity of Alvarado in the diagnostic accuracy of appendicectomy were 75.2% and 61.3% (CI = 95%), respectively. The sensitivity of ultrasound and CRP for predicting appendicitis was significantly higher than the Alvarado criteria. The diagnostic accuracy for CRP was significantly higher than ultrasound (64.9% vs. 60.7%, P: 0.003). The diagnostic accuracy of the simultaneous use of Alvarado + CRP and CRP + Ultrasound was significantly higher than that of Alvarado + ultrasound. The sensitivity, specificity, and diagnostic accuracy of the simultaneous use of all three criteria together (Alvarado + Ultrasound + CRP) were estimated to be 94.9%, 25.8%, and 81.5% (CI = 95%), respectively, which were significantly higher than the use of other criteria. CONCLUSION: This study showed that the Alvarado criteria had inadequate diagnostic sensitivity and accuracy for diagnosing acute appendicitis. The diagnostic accuracy of acute appendicitis increases to over 90% using the three Alvarado, ultrasound, and CRP criteria at the same time.

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.

BACKGROUNDS: We aimed to investigate surgeons in training knowledge of clinical decision rules (CDR) for diagnosing appendicitis and their attitudes toward implementing them. METHODS: We included surgeons in training practicing in East Denmark who independently could decide to perform a diagnostic laparoscopy for suspected appendicitis. The survey was developed in Research Electronic Data Capture and face-validated before use. It consisted of three parts: (1) the characteristics of the surgeons, (2) their diagnostic approach, and (3) their knowledge and attitude toward introducing CDR in the clinic. Data were collected in January 2023. RESULTS: We achieved 83 (90%) responses, and 52% of surgeons in training believed that appendicitis was difficult to diagnose. Their diagnostic approach mostly included symptoms and physical examinations for abdominal pain, and C-reactive protein. A total of 48% knew of at least one clinical decision rule, and 72% had never used a clinical decision rule. Regarding the necessity of CDR in clinical practice, surgeons in training options were divided into thirds: not needed, neither needed nor not needed, and needed. Surgeons in training indicated that CDR needed to be validated and easily applied before they would implement them. CONCLUSION: Approximately 3/4 of surgeons in training had never utilized a clinical decision rule to diagnose appendicitis, and only half knew of their existence. The symptoms and findings incorporated in most CDR aligned with their diagnostic approach. They were conflicted if CDR needed to be implemented in clinical practice.

BACKGROUND: Acute appendicitis remains the most common surgical emergency worldwide. There has been a low uptake of laparoscopic appendicectomy in the South African public sector. Preoperative identification of cases of uncomplicated appendicitis that are amenable to a laparoscopic approach may facilitate the implementation of laparoscopic appendicectomy programs in training hospitals. With limited access to preoperative imaging, alternative strategies for this preoperative prediction are needed. METHODS: A retrospective audit of patients over the age of 12 years with a histologically confirmed diagnosis of acute appendicitis over a 5-year period was performed. Patients were categorized as uncomplicated or complicated appendicitis and C-reactive protein (CRP) and white cell count (WCC) reviewed. Receiver operating characteristics curves were constructed for these blood tests and acute appendicitis severity. Youden's J statistic was used to determine optimal cut off values for diagnosing complicated appendicitis. RESULTS: 358 patients had confirmed appendicitis and complete blood results. Of these, 189 (52.79%) had complicated appendicitis with a 40.22% perforation rate. Median CRP in uncomplicated and complicated groups were 68 mg/L (IQR 19-142) and 216 mg/L (IQR 103-313) with an area under the curve (AUC) of 0.75 (95% CI: 0.70-0.80). The median WCC in the two groups were 12.6 × 109 cells/L (IQR 9.9-15.6) and 14.4 × 109 cells/L (IQR 11.5-18.28) with an AUC of 0.61 (95% CI: 0.56-0.67). The optimal cut off value for CRP was found to be 110 mg/L with a sensitivity of 74.74% and specificity of 69.23%. CONCLUSION: A cutoff value of 110 mg/dl CRP can distinguish patients with early appendicitis from those with complicated disease and when used in conjunction with clinical assessment may help identify patients in whom laparoscopic appendicectomy is appropriate.

Accurate diagnosis of paediatric appendicitis remains a challenge due to its diverse clinical presentations and reliance on subjective assessments. The integration of artificial intelligence (AI) with an expert's ''clinical sense'' has the potential to improve diagnostic accuracy. In this study, we aimed to evaluate the effectiveness of the Artificial Intelligence Pediatric Appendicitis Decision-tree (AiPAD) model in enhancing the diagnostic capabilities of trainees and compare their performance with that of an expert supervisor. Between March 2019 and October 2022, we included paediatric patients aged 0-12 years who were referred for suspected appendicitis. Trainees collected clinical findings using five predefined parameters before ordering any imaging studies. The AiPAD model, which was blinded to the surgical team, made predictions from the supervisor's and trainees' findings independently. The diagnosis verdicts of the supervisor and the trainees were statistically evaluated in comparison to the prediction of the AI model, taking into account the revealed correct diagnosis. A total of 136 cases were included, comprising 58 cases of acute appendicitis (AA) and 78 cases of non-appendicitis (NA). The supervisor's correct verdict showed 91% accuracy compared to an average of 70% for trainees. However, if trainees were enabled with AiPAD, their accuracy would improve significantly to an average of 97%. Significantly, a strong association was observed between the expert's clinical sense and the predictions generated by AiPAD. CONCLUSION: The utilisation of the AiPAD model in diagnosing paediatric appendicitis has significant potential to improve trainees' diagnostic accuracy, approaching the level of an expert supervisor. This hybrid approach combining AI and expert knowledge holds promise for enhancing diagnostic capabilities, reducing medical errors and improving patient outcomes. WHAT IS KNOWN: ⢠Sharpening clinical judgement for pediatric appendicitis takes time and seasoned exposure. Traditional training leaves junior doctors yearning for a faster path to diagnostic mastery. WHAT IS NEW: ⢠AI-generated models unlock the secrets of expert intuition, crafting an explicit guide for juniors to rapidly elevate their diagnostic skills. This leapfrog advancement empowers young doctors, democratizing medical expertise and paving the way for brighter outcomes in clinical training.

The involvement of kidney, perirenal fat, and ureter is a rare variant of inguinal hernia. We report a case of a 78-year-old man presenting with typical clinical signs of acute appendicitis. Ultrasonography and CT scan revealed ptosis of the right kidney with a major part of the perirenal capsule involved in a large right sided inguinal hernia with acute obstruction of the ureter and urostasis. Acute surgery was performed, involving resection of perirenal fat, liberation, resection, and neoimplantation of the ureter, and hernioplasty. The postoperative period was uneventful. This case illustrates diagnostic unpredictability of acute appendicitis as well as anatomic variety of inguinal hernias.

INTRODUCTION: Acute pain in the right lower quadrant during pregnancy is difficult to approach and acute appendicitis must be excluded. The complication rate in pregnant acute appendicitis increases as a result of delayed diagnosis due to physiological and anatomic changes. The systemic immune inflammatory index (SII), which includes several inflammatory tests, is considered to be a good indicator of acute inflammation. The aim of the present study was to investigate the diagnostic value of SII in the diagnosis of acute appendicitis and complicated appendicitis in pregnant women. MATERIAL-METHOD: This was designed as a retrospective, single-center case-control study. This study was performed in pregnant women over 12 weeks of gestation who were diagnosed with acute appendicitis as indicated by pathology report and met the inclusion criteria. Vital parameters, demographic characteristics, laboratory values, presence of complicated appendicitis, and pathology reports were taken into analysis. RESULTS: The present study was performed with 76 pregnant women, including 38 pregnant women with acute appendicitis and 38 pregnant women with healthy controls. SII had a sensitivity of 82.0% and specificity of 66.7% with a cut-off value of 840.13 in pregnant acute appendicitis cases (AUC: 0.790; 95% CI: 0.686-0.984; p < 0.001) and SII level was significantly higher in complicated appendicitis cases with a sensitivity and specificity of 66.7% and 91.3%, respectively, with a cut-off value of 2301.66 (AUC: 0.812; 95% CI: 0.665-0.958; p = 0.001). CONCLUSION: SII is a cost-effective, rapid, easily calculated, and powerful marker that can be used for the diagnosis of both acute and complicated appendicitis in pregnant patients.

BACKGROUND: The distinction between complicated and uncomplicated acute appendicitis (AA) is important as it guides postoperative antibiotic treatment. A diagnosis based on intraoperative findings is imprecise and standard cultivation of peritoneal fluid is generally time-consuming with little clinical benefit. The aim of this study was to examine if cultivation of peritoneal fluid in acute appendicitis could reliably detect bacteria within 24 h. METHODS: Patients older than 18 years undergoing laparoscopic appendectomy were prospectively enrolled at two surgical departments after informed consent was obtained. Periappendicular fluid was collected prior to appendectomy and sent for cultivation. Sensitivity, specificity and positive and negative predictive values were calculated with 95% confidence intervals (CIs) using 72-hour cultivation results as the gold standard. Patients with complicated AA as determined by the surgeon, received a three-day course of oral antibiotics. Postoperative infectious complications within 30 days after surgery were registered. RESULTS: From July 2020 to January 2021, 101 patients were included. The intraoperative diagnosis was complicated AA in 34 cases. Of these patients, six (17.6%) had bacteria cultured within 24 h after surgery, leading to a sensitivity of 60% and a specificity of 100%. The positive and negative predictive values were 1.00 and 0.96, respectively. Seven patients developed a postoperative infection (five superficial wound infections and two intra-abdominal abscess). In all cases with a positive cultivation result, the intraoperative diagnosis was complicated appendicitis and a postoperative course of antibiotics prescribed. CONCLUSION: Twenty-four-hour cultivation of the peritoneal fluid in acute appendicitis is a valid indicator for peritoneal bacterial contamination. Randomized studies are necessary to determine if this approach is suitable for targeting postoperative antibiotic treatment as a means to prevent overtreatment without increasing the risk of infectious complications.

BACKGROUND: The objective of this study was to assess the likelihood of acute appendicitis (AA) in children presenting with abdominal symptoms at the emergency department (ED), based on their prior primary care (PC) consultation history. METHODS: Between February and June 2021, we prospectively enrolled all children presenting at the ED with acute abdominal pain indicative of possible acute appendicitis (AA). Subsequently, they were categorized into three groups: those assessed by a PC physician (PG), those brought in by their family without a prior consultation (FG), and those admitted after a PC consultation without being assessed as such. The primary objective was to assess the probability of AA diagnosis using the Pediatric Appendicitis Score (PAS). Secondary objectives included analyzing PAS and C-reactive protein (CRP) levels based on the duration of pain and final diagnoses. RESULTS: 124 children were enrolled in the study (PG, n = 56; FG, n = 55; NG, n = 13). Among them, 29 patients (23.4%) were diagnosed with AA, with 13 cases (23.2%) from the PG and 14 cases (25.4%) from the FG. The mean PAS scores for AA cases from the PG and FG were 6.69 ± 1.75 and 7.57 ± 1.6, respectively, (p = 0.3340). Both PAS scores and CRP levels showed a significant correlation with AA severity. No cases of AA were observed with PAS scores < 4. CONCLUSIONS: There was no significant difference in PAS scores between patients addressed by PG and FG, even though PAS scores tended to be higher for patients with AA. We propose a new decision-making algorithm for PC practice, which incorporates inflammatory markers and pain duration.

OBJECTIVE: The aim of this study is to identify risk factors associated with acute complicated appendicitis (CA) in children aged three years or younger, providing a theoretical foundation for the management and treatment of acute appendicitis (AA). METHODS: A retrospective analysis was conducted on 135 pediatric patients with AA, admitted to the Department of General Surgery at Anhui Children's Hospital between December 2020 and December 2023, who underwent successful surgical treatment. Based on the intraoperative and postoperative pathological findings, patients were categorized into two groups: complicated appendicitis (CA) (n = 97 cases) and uncomplicated appendicitis (UA) (n = 38 cases). Clinical data including gender, age, weight, disease duration, preoperative white blood cell count (WCC), neutrophil granulocyte (NEUT) count, C-reactive protein (CRP) levels, total bilirubin (TBil) levels, procalcitonin (PCT) levels, calprotectin (Cal) levels, preoperative ultrasound results indicating the presence or absence of fecaliths, maximum appendix diameter, and pediatric appendicitis sore (PAS) were collected and analyzed. Comparative analysis was performed to investigate the differences between the groups and identify risk factors of CA. RESULTS: The CA group exhibited significantly higher values in disease duration, CRP levels, PCT, Cal, presence of appendiceal fecaliths, maximum appendix diameter, and PAS compared to the UA group (P < 0.05). Multivariate analysis identified CRP levels, maximum appendix diameter, and PAS as independent risk factors for CA. Specifically, differences in CRP level (OR = 1.045, 95% CI:1.024 ~ 1.067, P < 0.001), PAS (OR = 1.768, 95% CI:1.086 ~ 2.879, P = 0.022), and maximum appendix diameter (OR = 1.860, 95% CI:1.085 ~ 3.191, P = 0.024) were significant. The area under the receiver operating characteristic curve values were 0.6776 for the PAS, 0.7663 for CRP, and 0.5604 for the maximum appendix diameter. CONCLUSION: CRP levels, PAS, and maximum appendix diameter are independent risk factors for CA in children under three years of age. These parameters are valuable for the early diagnosis of CA.

BACKGROUND: Acute appendicitis is the most common surgical emergency in Ethiopian clinical practice. Although a multitude of scoring systems have been used in clinical practice, none have been universally validated. The purpose of this study was to validate the Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scoring system in the Ethiopian context. METHODS: A total of 315 consecutive patients who presented with a presumptive diagnosis of acute appendicitis and were planned to undergo appendectomy were studied. All the studied patients had diagnostic sonography and underwent the RIPASA scoring system. The sensitivity, specificity, positive predictive value, and negative predictive value of RIPASA and ultrasound results with intraoperative gross examinations. RESULTS: The mean age of the participants was 27.4 ± 11.5 years, with a male-to-female ratio of 1.6:1. The concordance between ultrasound and RIPASA for the diagnosis of acute appendicitis was 93.6%. The sensitivity, specificity, positive predictive value, and negative predictive value of RIPASA were 96.2%, 30.8%, 93.9%, and 42.1%, respectively. Similarly, the sensitivity, specificity, positive predictive value, and negative predictive value of ultrasound were 95.3%, 27.8%, 95.6%, and 26.3%, respectively. White cell count and RIPASA scores were weakly correlated with intraoperative stages of acute appendicitis, r(313) = 0.18, p = 0.001, and r(313) = 0.129, p = 0.022, respectively. The rate of a negative appendectomy was 6%. CONCLUSION: RIPASA and ultrasound had equivalent performance in the diagnosis of acute appendicitis. In both cases, the rate of negative appendectomy was low enough to validate RIPASA for clinical practice in low-income institutions where sonographic diagnosis by a conventionally trained radiologist is not available.

BACKGROUND: The aims of this study were to summarize the clinical presentation and histological results of 20 cases of complicated Meckel diverticulum (MD) who were presumed to have acute appendicitis before surgery, as well as to improve the diagnosis and treatment of complicated MD in children. MATERIALS AND METHODS: We retrospectively reviewed the records of 20 complicated MD admitted to our institution who were preoperatively diagnosed with acute appendicitis from January 2012 to January 2019. Patients were divided into the perforated MD group and the Meckel's diverticulitis group. Patient demographics, clinical manifestations, laboratory data, auxiliary examinations, surgical methods, and the result of heterotopic tissue were recorded. RESULTS: A total of 20 cases of complicated MD (perforated or diverticulitis) were identified. Children were aged from 3 to 13 years, with a mean age of 7.75 years (median 7.75; range, 1-13 years). Perforated Meckel's diverticulum occurred in 5 of 20 (25%) cases. For perforated MD versus diverticulitis, no significant differences were found between age, time to intervention, length of hospital stay, and distance from the ileo-cecal valve. Heterotopic tissue was confirmed on histopathology in 75% of all patients, including 10 cases of gastric mucosa, 3 cases of coexistent gastric mucosa and pancreatic tissue, and 2 cases of pancreatic tissue. All patients underwent diverticulectomy or partial ileal resection under laparoscopy or laparotomy; two cases combined with appendectomy owing to slight inflammation of the appendix. CONCLUSIONS: The most common presentation of symptomatic MD is painless rectal bleeding; however, it can present symptoms of acute abdomen mimicking acute appendicitis. The key point of diverticulectomy is to remove the ectopic mucosa completely.

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

BACKGROUND: Acute appendicitis is a common cause of abdominal pain leading to emergent abdominal surgery in children. C-reactive protein (CRP), an inflammatory marker typically elevated in acute appendicitis, and Pediatric Appendicitis Score (PAS), a clinical scoring system used for the diagnosis of appendicitis, have the potential to predict the severity of inflammation of the appendix. This may be useful in helping the physician make a treatment plan prior to surgery. OBJECTIVE: The purpose of this study was to assess whether CRP value and PAS differ with the extent of inflammation of the appendix seen on histologic examination. METHODS: This was a prospective observational study of patients diagnosed with acute appendicitis via computed tomography or ultrasound. Enrolled patients had CRP levels drawn, PAS calculated, and appendix pathology reviewed. Appendix pathology was categorized by the pathologist on the basis of the level of inflammation: simple, suppurative, gangrenous, and perforated. RESULTS: One hundred sixty-three patients were enrolled. CRP levels and PAS were statistically different (p < 0.002) among the four pathology classifications. Patients with simple appendicitis (n = 3) had a mean CRP of 2.95 mg/L and PAS of 3.9, patients with suppurative appendicitis (n = 99) had a mean CRP of 26.89 mg/L and PAS of 6.5, patients with gangrenous appendicitis (n = 56) had a mean CRP of 91.11 mg/L and PAS of 7.5, and patients with perforated appendicitis (n = 6) had a mean CRP of 154.17 mg/L and PAS of 7. The results remained statistically significant (p < 0.002) after adjusting for age, race, and sex. When combined-PAS ≥ 8 and CRP level > 40 mg/L-the specificity of complicated appendicitis was 91.2% and positive predictive value was 72.7%. CONCLUSIONS: Higher CRP levels and PAS were associated with increased histologic inflammation of the appendix. This study provides preliminary evidence that CRP and PAS could potentially assist in treatment decisions for appendicitis.

Hungatella species, including Hungatella hathewayi and Hungatella effluvii, previously identified as part of the Clostridium genus, are anaerobic bacteria primarily residing in the gut microbiome, with infrequent implications in human infections. This article presents the case of an 87-year-old Asian male admitted for a hyperosmolar hyperglycemic state with septic shock secondary to Hungatella hathewayi bacteremia originating from acute appendicitis. Remarkably, the bacterium was detected in the blood 48 hours before the emergence of clinical and radiographic evidence of acute appendicitis. Additionally, we conducted a literature review to identify all documented human infections caused by Hungatella species. Timely microbial identification in such cases is essential for implementing targeted antibiotic therapy and optimizing clinical outcomes.

The aim of this study was to analyze the role of thiol/disulfide homeostasis (TDH) parameters as an indicator of oxidative stress in acute appendicitis (AA). PubMed, EMBASE, Web of Science, and Scopus databases were systematically searched. Studies reporting on TDH in AA (both complicated and uncomplicated cases) were included. The comparator group were healthy controls. The TDH domain was compared between the groups using anti-oxidant parameters, namely native thiol and total thiol levels, and native thiol/total thiol ratio; and oxidant parameters, namely disulfide level, disulfide/native thiol ratio, and disulfide/total thiol ratio. The statistical analysis was performed using a random-effects model. The methodological quality of the studies was assessed utilizing the Newcastle-Ottawa scale. Eleven studies with a total of 926 subjects, comprising 457 patients with uncomplicated appendicitis, 147 with complicated appendicitis, and 322 healthy controls were included. Our study demonstrated significantly increased oxidative stress in AA as compared to healthy controls in all TDH parameters and significantly lower total thiol levels in complicated AA as compared to uncomplicated AA. Due to a poor methodological quality in five out of eleven studies, future prospective studies with adequate power are essential to validate these observations and refine the diagnostic approaches to AA.
