Multicenter validation of an artificial intelligence (AI)-based platform for the diagnosis of acute appendicitis. Surgery 2024; 176:569-576. [PMID: 38910047 DOI: 10.1016/j.surg.2024.05.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 04/20/2024] [Accepted: 05/06/2024] [Indexed: 06/25/2024]
Abstract
BACKGROUND The current scores used to help diagnose acute appendicitis have a "gray" zone in which the diagnosis is usually inconclusive. Furthermore, the universal use of CT scanning is limited because of the radiation hazards and/or limited resources. Hence, it is imperative to have an accurate diagnostic tool to avoid unnecessary, negative appendectomies. METHODS This was an international, multicenter, retrospective cohort study. The diagnostic accuracy of the artificial intelligence platform was assessed by sensitivity, specificity, negative predictive value, the area under the receiver curve, precision curve, F1 score, and Matthews correlation coefficient. Moreover, calibration curve, decision curve analysis, and clinical impact curve analysis were used to assess the clinical utility of the artificial intelligence platform. The accuracy of the artificial intelligence platform was also compared to that of CT scanning. RESULTS Two data sets were used to assess the artificial intelligence platform: a multicenter real data set (n = 2,579) and a well-qualified synthetic data set (n = 9736). The platform showed a sensitivity of 92.2%, specificity of 97.2%, and negative predictive value of 98.7%. The artificial intelligence had good area under the receiver curve, precision, F1 score, and Matthews correlation coefficient (0.97, 86.7, 0.89, 0.88, respectively). Compared to CT scanning, the artificial intelligence platform had a better area under the receiver curve (0.92 vs 0.76), specificity (90.9 vs 53.3), precision (99.8 vs 98.9), and Matthews correlation coefficient (0.77 vs 0.72), comparable sensitivity (99.2 vs 100), and lower negative predictive value (67.6 vs 99.5). Decision curve analysis and clinical impact curve analysis intuitively revealed that the platform had a substantial net benefit within a realistic probability range from 6% to 96%. CONCLUSION The current artificial intelligence platform had excellent sensitivity, specificity, and accuracy exceeding 90% and may help clinicians in decision making on patients with suspected acute appendicitis, particularly when access to CT scanning is limited.

Abstract
INTRODUCTION From a surgeon's perspective, appendicitis is treated with appendectomy and sometimes a normal appendix is removed. This study aimed to investigate the patients' perspectives on having surgery but not appendicitis and their involvement in treatment decisions. METHODS This study is reported according to the COnsolidated criteria for REporting Qualitative research (COREQ) guideline. Eligible participants either had a normal diagnostic laparoscopy with no resection of the appendix or a negative appendectomy confirmed by histopathology. Interviews were conducted using a semi-structured interview guide and transcribed verbatim. Data were analyzed using content analysis. RESULTS This study consisted of 15 interviews. Analysis of the interviews resulted in the formulation of four categories: (1) discovering the results of the histopathology report, (2) thoughts on having a normal appendix removed or left in situ, (3) the scarce use of shared decision-making, and (4) general anesthesia and the risk of a burst appendix made the participants nervous. CONCLUSION The amount of information communicated to the patients before and after surgery was sparse. The participants were not aware of the histopathology results and the participants were not involved in decision-making and were generally anxious about anesthesia and a burst appendix.

Observation Safely Reduces the Use of the Computerized Tomography in Medium-to-Low-Risk Patients with Suspected Acute Appendicitis: Results of a Randomized Controlled Trial. J Clin Med 2024; 13:3363. [PMID: 38929896 PMCID: PMC11203661 DOI: 10.3390/jcm13123363] [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: 04/18/2024] [Revised: 05/28/2024] [Accepted: 06/05/2024] [Indexed: 06/28/2024] Open
Abstract
Objectives-The objective was to compare the effectiveness of observation in standard-of-care computed tomography (CT) in adult patients with suspected acute appendicitis (AA). Methods-Patients with clinically suspected AA and inconclusive diagnosis after primary clinical examination, laboratory examination, and transabdominal ultrasound (TUS) were eligible for the study, and they were randomized (1:1) to parallel groups: observation-group patients were observed for 8-12 h and then, repeated clinical and laboratory examinations and TUS were performed; CT group (control group) patients underwent abdominopelvic CT scan. The study utilized Statistical Analysis System 9.2 for data analysis, including tests, logistic regression, ROC analysis, and significance evaluation. Patients were enrolled in the study at Vilnius University Hospital Santaros Klinikos in Lithuania between December 2018 and June 2021. Results-A total of 160 patients (59 men, 101 women), with a mean age of 33.7 ± 14.71, were included, with 80 patients in each group. Observation resulted in a reduced likelihood of a CT scan compared with the CT group (36.3% vs. 100% p < 0.05). One diagnostic laparoscopy was performed in the observation group; there were no cases of negative appendectomy (NA) in the CT group. Both conditional CT and observation pathways resulted in high sensitivity and specificity (97.7% and 94.6% vs. 96.7% and 95.8%). Conclusions-Observation including the repeated evaluation of laboratory results and TUS significantly reduces the number of CT scans without increasing NA numbers or the number of complicated cases.

Abstract
There are two types of treatment for acute appendicitis (AA): surgery and antibiotic therapy. Some patients with complex appendicitis are treated with surgery; however, for uncomplex appendicitis, most could be treated effectively with antibiotics instead. How to distinguish complex appendicitis from uncomplex appendicitis before surgery is currently unknown. The present study aimed to assess the efficacy of the laboratory parameters to diagnose complicated appendicitis. Data from 1,514 cases with acute appendicitis who were admitted to Beijing Tsinghua Changgung Hospital and Beijing Aerospace General Hospital (both Beijing, China) from January 2016 to September 2021 were retrospectively analyzed. All cases were divided into uncomplicated and complicated appendicitis. Independent variables were analyzed by uni- and multivariate logistic regression analyses. Receiver operating characteristic (ROC) curve analysis was used to identify significant parameters in the multivariate logistic regression analysis. Cut-off values, sensitivity, specificity and accuracy with area under the curve (AUC)>0.600 were considered significant parameters. Significant differences were found in age (P<0.001), body temperature (P<0.001), white blood cell (WBC) count (P<0.001), C-reactive protein (CRP; P<0.001), neutrophil count (P<0.001), neutrophil-to-lymphocyte ratio (NLR, P=0.019), platelet-to-lymphocyte ratio (PLR, P<0.001), platelet count (P<0.001), coefficient of variation (CV) and standard deviation (SD) of red blood cell distribution width (RDW); both P<0.001), mean platelet volume (MPV, P<0.001) and total (P<0.001) and direct bilirubin (P<0.001) between the two groups. CRP, neutrophil count, NLR, PLR, platelet count, RDW-CV, RDW-SD, MPV and direct bilirubin levels were found as the independent variables to diagnose complicated appendicitis. In patients with acute appendicitis, CRP >22.95 mg/l, NLR >5.7, serum direct bilirubin >6.1 mmol/l and RDW-SD>17.7 fl were significantly associated with complicated appendicitis.

Abstract
INTRODUCTION Acute right iliac fossa (RIF) pain is a common presenting symptom in surgical patients, with a wide range of differentials, particularly in premenopausal females. This study explores ultrasound usage in the management of women aged 16-55 years presenting with RIF pain. METHODS A total of 1,082 patients who presented to a tertiary hospital over 12 months were included. Data were collected from patients' electronic records, including initial clinical impression, imaging, management, operative findings, histology and subsequent hospital attendances within 6 weeks and within 6 months. RESULTS Following clinical assessment, 607 (56%) of patients underwent an ultrasound. Of these, 280 (25.9%) patients received no radiological imaging on initial presentation, and 252 (42%) had pathology identified on ultrasound. The most common finding was an ovarian cyst, closely followed by unexplained free pelvic fluid. Of the 607 patients scanned, 29 (4.8%) had an ultrasound diagnosis of appendicitis; 254 of 1,082 (23.5%) patients underwent operative management. Of the 254 patients who had surgery, 179 (70.5%) had preoperative imaging. Of the 29 (11.4%) cases where the intraoperative finding was gynaecological, 15 (51.7%) cases had not had any preoperative imaging. The negative appendicectomy rate was 21.3% (45/211). Of the 45 patients who had a histologically normal appendix, 22 (48.9%) had not had any previous imaging. Ultrasound had a specificity of 78% for diagnosing appendicitis. CONCLUSIONS In patients who underwent operative management, a negative finding or finding not requiring surgical management was associated with no preoperative imaging. This supports the use of ultrasound scans as an adjunct in a multimodal approach to the assessment of women presenting with RIF pain.

Abstract
INTRODUCTION Correct diagnosis of acute appendicitis may sometimes be challenging. The Negative appendectomy rate (NAR) has declined in the recent years in Europe and USA, in part due to better diagnostic imaging tools. The aim of this study was to examine the rates of negative appendectomy in our institution, investigate trends in its incidence, and identify possible predicting factors. METHODS A retrospective cohort study, including all patients younger than 18 years of age who underwent an appendectomy between 2007 and 2021 in a single tertiary medical center. Data regarding patient's demographics, laboratory and imaging results, pathological results and clinical outcome were collected. RESULTS Between 2007 and 2021, a total of 3937 pediatric patients underwent appendectomy due to a working diagnosis of acute appendicitis. Overall, 143 patients (3.6%) had normal appendix on pathological examination. However, in the last 5 years, the rate of normal appendix was 1.9%, together with an increased rate of pre-operative imaging (from 40% to nearly 100%). CONCLUSION Low NAR under 2% is an achievable benchmark in the era of accessible pre-operative imaging. In unequivocal cases, a secondary survey that includes repeated physical examination, blood work and imaging is recommended and may result in near-zero rates of NAR.

Abstract
BACKGROUND In acute appendicitis, decision-making around operative intervention for paediatric patients differs from adults due to a higher weight placed on clinical assessment and reduced rates of cross-sectional imaging. In regional settings, non-paediatric emergency doctors, general surgeons, and radiologists usually assess and manage this patient group. Differences have been observed in paediatric negative appendicectomy rates between general and paediatric centres. METHODS A retrospective cohort study was performed, identifying paediatric patients undergoing emergency appendicectomy at the Southwest Health Campus (Bunbury, Western Australia) from 2017 to 2021. The primary outcome measure was histopathology confirming the absence of transmural inflammation of the appendix. In addition, clinical, biochemical and radiological data were collected to identify predictors of negative appendicectomy (NA). Secondary outcome measures were hospital length-of-stay and post-operative complication rates. RESULTS Four hundred and twenty-one patients were identified, of which 44.9% had a negative appendicectomy. Statistically significant associations between female gender, white cell count less than 10 × 109 , neutrophil ratio less than 75%, low CRP and NA were observed. NA was not associated with a lower risk of re-admission or complications compared with appendicectomy for appendicitis. CONCLUSIONS Our centre's NA rate is higher than that observed in the literature at both non-paediatric and paediatric surgical centres. NA has similar morbidity risk to appendicectomy for uncomplicated appendicitis and offers a timely reminder that diagnostic laparoscopy in children is not benign.

Risk factors for postoperative morbidity, prolonged length of stay and hospital readmission after appendectomy for acute appendicitis. Eur J Trauma Emerg Surg 2023; 49:1355-1366. [PMID: 36708422 DOI: 10.1007/s00068-023-02225-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 01/09/2023] [Indexed: 01/29/2023]
Abstract
PURPOSE The aim of the present study was to identify risk factors associated with postoperative morbidity and major morbidity, with a prolonged length of hospital stay and with the need of readmission in patients undergoing appendectomy due to acute appendicitis. METHODS We performed a retrospective analysis of 1638 adult patients who underwent emergency appendectomy for preoperatively suspected acute appendicitis from 2010 to 2020 at the University Hospital Erlangen. Data including patient demographics, pre-, intra-, and postoperative findings were collected and compared between different outcome groups (morbidity, major morbidity, prolonged length of postoperative hospital stay (LOS) and readmission) from those patients with verified acute appendicitis (n = 1570). RESULTS Rate of negative appendectomies was 4%. In patients with verified acute appendicitis, morbidity, major morbidity and readmission occurred in 6%, 3% and 2%, respectively. Mean LOS was 3.9 days. Independent risk factors for morbidity were higher age, higher preoperative WBC-count and CRP, lower preoperative hemoglobin, longer time to surgery and longer duration of surgery. As independent risk factors for major morbidity could be identified higher age, higher preoperative CRP, lower preoperative hemoglobin and longer time to surgery. Eight parameters were independent risk factors for a prolonged LOS: higher age, higher preoperative WBC-count and CRP, lower preoperative hemoglobin, need for conversion, longer surgery duration, presence of intraoperative complicated appendicitis and of postoperative morbidity. Presence of malignancy and higher preoperative WBC-count were independent risk factors for readmission. CONCLUSION Among patients undergoing appendectomy for acute appendicitis, there are relevant risk factors predicting postoperative complications, prolonged hospital stays and readmission. Patients with the presence of the identified risk factors should receive special attention in the postoperative course and may benefit from a more individualized therapy.

Diagnostic Accuracy Rates of Appendicitis Scoring Systems for the Stratified Age Groups. Emerg Med Int 2022; 2022:2505977. [PMID: 36353722 PMCID: PMC9640239 DOI: 10.1155/2022/2505977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 10/28/2022] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND Many scoring systems have been developed for acute appendicitis, which is the most common emergent disorder in surgical practice. Considering the physiological changes and chronic diseases occurring with advancing age, an applied scoring system may not produce the same score in similar patients in all age groups. OBJECTIVES We aimed to compare the predictive values of scoring systems in different age groups. METHODS In this prospective study, the patients operated on in our clinic with a prediagnosis of acute appendicitis between March 2020 and March 2021 were included. We divided them into three age groups as 18-45 years (group 1), 46-65 years (group 2), and >65 years (group 3). We compared the scores of the nine acute appendicitis scoring systems most commonly used in the literature for these age groups. RESULTS A total of 203 patients were included in our study. The Alvarado scoring system yielded the most accurate results for group 1, whereas the Fenyo-Linberg scoring system was the most accurate system for group 2 and the Eskelinen scoring system for group 3. CONCLUSION Age should be considered as a major parameter during the selection of the scoring system to be applied for patients with prediagnosis of acute appendicitis. Our study revealed the Alvarado and the Fenyo-Lindberg scoring systems as the most accurate systems for the differential diagnosis of appendicitis in the 18-45 and 46-65 years age groups, respectively. Although we found the Eskelinen scoring system as the most accurate one in the >65 years age group, the confidence intervals indicated that it may not be appropriate for use alone in this group.

A case-crossover study in Tongling, China. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2022; 66:2083-2090. [PMID: 35913519 DOI: 10.1007/s00484-022-02342-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 04/12/2022] [Accepted: 07/25/2022] [Indexed: 06/15/2023]
Abstract
Existing studies suggested that ambient temperature may affect the attack of acute appendicitis. However, the identification of the quantitative effect and vulnerable populations are still unknown. The purposes of this study were to quantify the impact of daily mean temperature on the hospitalization of acute appendicitis and clarify vulnerable groups, further guide targeted prevention of acute appendicitis in Tongling. Daily data of cases and meteorological factors were collected in Tongling, China, during 2015-2019. Time stratified case-crossover design and conditional logistic regression model were used to evaluate the odds ratio (OR) of ambient temperature on hospitalizations for acute appendicitis. Stratified analyses were performed by sex, age, and marital status. The odds ratio (OR) of hospitalizations for acute appendicitis increased by 1.6% for per 1 ℃ rise in mean temperature at lag3[OR = 1.016, 95% confidence interval (CI): 1.004-1.028]. In addition, our results suggest it is in the women that increased ambient temperature is more likely to contribute to acute appendicitis hospitalizations; we also found that the married are more susceptible to acute appendicitis hospitalizations due to increased ambient temperature than the unmarried; people in the 21-40 years old are more sensitive to ambient temperature than other age groups. The significant results of the differences between the subgroups indicate that the differences between the groups are all statistically significant. The elevated ambient temperatures increased the risk of hospitalizations for acute appendicitis. The females, married people, and patients aged 21-40 years old were more susceptible to ambient temperature. These findings suggest that more attention should be paid to the impact of high ambient temperature on acute appendicitis in the future.

Abstract
BACKGROUND Right iliac fossa (RIF) pain is a common indication for laparoscopy to diagnose and treat appendicitis. When a macroscopically normal appendix is found, there is no standard consensus regarding excision. Some surgeons remove the appendix due to the risk of microscopic inflammation and to avoid a future, repeat laparoscopy for possible appendicitis. Alternatively, others leave the appendix in situ to avoid morbidity from a potentially unnecessary procedure. We aimed to evaluate the outcomes of patients with macroscopically normal appendices left in situ. METHODS All emergency laparoscopies without appendicectomy between January 1st 2010- December 31st 2020 were identified from theatre records. All operative notes were individually evaluated and comments on the macroscopic appearance of the appendix and any intra-operative pathology were recorded. Only patients undergoing laparoscopy for suspected appendicitis with macroscopically normal appendices were included. RESULTS A total of 120 patients [median age 21.68 (range 9-90.8) years] were included. The cohort was predominantly female (n=105, 87.5%). Forty-eight patients (40.0%) had a positive finding during index laparoscopy. During a median duration of 94.5 (range 8-131) months' follow-up, 16 patients (13.33%) underwent a repeat laparoscopy for recurrent RIF pain. Thirteen (10.8% of total cohort) subsequently underwent an appendicectomy. Histology confirmed acute appendicitis in six cases (4.17% of entire cohort). On subanalysis of smaller cohort, index laparoscopies with no positive findings (n=72), nine patients (12.5%) underwent appendicectomy with two (2.7%) appendices demonstrating appendicitis on histological examination. CONCLUSION 87% of the total cohort with a normal appendix at laparoscopy for RIF pain did not undergo further laparoscopy. Less than 5% of the total cohort and 2.7% of subanalysis cohort had an appendicectomy for histologically-proven appendicitis within the follow-up period. From the evidence in this study, we conclude that leaving the appendix in situ unless macroscopically inflamed is a viable alternative to excision.

Abstract
Although acute appendicitis remains the most common cause of acute abdomen in General Surgery practice, negative appendectomy rates are still high in particularly female patients. Appendicitis scoring systems considering gender can help the clinician to reduce negative appendectomy rates in females. This present study aims to compare the Lintula, Ripasa, Fenyo-Lindberg scoring systems, which use gender as a variable, with the Alvarado, Karaman, scoring systems to evaluate which CSS is more successful in the differential diagnosis of appendicitis in females. We analyzed the records of the patients operated on with a prediagnosis of acute appendicitis in our clinic between 2020 and 2021, retrospectively. Alvarado, adult appendicitis score (AAS), appendicitis inflammatory response score (AIRS), Ripasa, Karaman, Lintula, and Fenyo Lindberg scores were calculated for each patient. The patients were divided into two groups as male and female, according to gender. Receiver operator characteristic (ROC) curve analysis was used to identify the best cut-off value and assess the performance of the test score for appendicitis. Three hundred and sixty-three patients were included in the study. One hundred seventy-two (47.4%) of the patients were male, and 191 (52.6%) were female. Alvarado and AAS were the most valuable score in female (AUC: 0.805, sensitivity: 0.63, specificity: 0.83; and area under curve (AUC): 0.794, Sensitivity 0.71, Specificity: 0.76, respectively), male group (AUC: 0.828, Sensitivity: 0.71, Specificity: 0.83; and AUC: 0.834, Sensitivity 0.74, Specificity: 0.77, respectively), and when patients were not categorized by gender (AUC: 0.818, Sensitivity: 0.67 Specificity: 0.83; and AUC: 0.794, Sensitivity 0.71, Specificity: 0.76, respectively). Although the Alvarado scoring system is the first defined appendicitis scoring system, it seems as superior to the many scoring systems defined after it in predicting appendicitis, even in female patients.

Abstract
BACKGROUND Appendicitis is a common general surgical emergency. The role of removing a normal appendix is debated. However, this relies on accurate intra-operative diagnosis of a normal appendix by the operating surgeon. This study aimed to compare surgeon's intra-operative assessment to final histological result acute appendicitis in paediatric and adult patients. METHODS All patients who underwent appendicectomy over a 14-year period in a general surgical department were identified using the prospective Lothian Surgical Audit system and pathology reports retrieved to identify final histological diagnosis. Open appendicectomy was selected to examine, as the routine practise at our institution is to remove a normal appendix at open appendicectomy. RESULTS A total of 1035 open appendicectomies were performed for clinically suspected appendicitis. Sensitivity of intra-operative diagnosis of appendicitis with operating surgeon was high at 95.13% with no difference between trainee and consultant surgeon or between adult and paediatric cases. Specificity of intra-operative diagnosis was lower in the paediatric group (32.58%) than in the adult group (40.58%). Women had a higher rate of negative appendicectomy than men. CONCLUSION The results of this study highlight some discordance between histological evidence of acute appendicitis and intra-operative impression. Therefore other clinical variables and not just macroscopic appearance alone should be used when deciding to perform appendicectomy.

Abstract
BACKGROUND Globally, patients presenting with acute surgical disease in rural areas have poorer outcomes when compared to urban areas; little data are available regarding outcomes for New Zealand (NZ) rural patients. This study aimed to compare the surgical management of appendicitis in a large metropolitan centre with its regional referral centres. METHODS In this retrospective cohort study, patient data were collated from the studied centres between November 2014 and October 2019. In addition to patient demographics, patterns of referral and presentation, the primary outcome was time to the theatre; secondary outcomes were perforation rates, length of stay and complications. Data are presented as medians (interquartile range). RESULTS A total of 3533 patients underwent appendicectomy over the period studied. For those presenting directly to the metropolitan centre, the median wait-time to the theatre was 16 h (9.2-23.2); if patients were transferred, they waited for 20.8 h (13.6-27). Patients presenting to regional centres waited for 7.6 h (4.5-15.4, P < 0.001). Perforation rates for transferred patients were 31% which was greater than for those presenting to the metropolitan (20%) or regional centres (17%, P = 0.014). Complications were also highest in transferred patients (20%) when compared to the metropolitan (17%) or regional centres (10%, P < 0.001). CONCLUSION Patients who were transferred to Christchurch Hospital from rural centres without surgical services had a longer wait-time than those who presented to Christchurch Hospital directly or were treated in regional centres. This was associated with higher rates of perforated appendicitis.

Abstract
Background and Aim: Acute appendicitis (AA) is traditionally considered a clinical diagnosis and negative appendectomy (NA) rates vary across health-care systems. Computed tomography (CT) scans have been shown to aid in the reduction of NA rates. Our study aimed to determine the pre-operative imaging characteristics in patients undergoing appendectomy with eventual normal histology. Materials and Methods: An audit of all patients with a discharge diagnosis of AA was conducted from January 2011 to December 2015. Histology reports of all patients who underwent appendectomies were reviewed, and medical records of patients with NA were included in the study. To study the impact of CT scan reporting in NA patients, CT scan images of patients with NA were reviewed retrospectively by two blinded radiologists. Results: A total of 2603 patients underwent appendectomy for suspected AA, and NA rate was 3.34% (n=87). The mean age of patients with NA was 30.3 (14.8-69.8) years with no gender difference (51.7% male). Sixty-six (75.9%) patients had laparoscopic appendectomy with 3.5% open conversion rate. CT scans were done in 47 patients. Pre-operative CT scan report was more likely to report dilated appendix (n=26 [55.3%] vs. n=7 [14.9%], P=0.0001). Post-operative blinded radiology review was more like to report other pathology (n=27 [57.4%] vs. n=2 [4.3%], P=0.0001) and normal appendix (n=26 [55.3%] vs. n=5 (10.6%), P=0.0001). Conclusion: The NA rate is low. There needs to be standardized reporting for imaging features of prominent/dilated appendix. Relevance for Patients: Appendectomy must be avoided in patients with a normal CT scan and when another pathological diagnosis is established. Liberal imaging policy assists to reduce NA rates. Imaging features of prominent or dilated appendix can be subjective and international collaboration is needed to define thresholds for imaging diagnosis of AA.

[PMID: 33169297 PMCID: PMC7652586 DOI: 10.1007/s00423-020-02023-6] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 11/02/2020] [Indexed: 12/14/2022]
Abstract
Purpose The COVID-19 pandemic has reformed global healthcare delivery. On 25 March 2020, Intercollegiate guidelines were published in the UK to promote safe surgical provision during the COVID-19 outbreak advocating non-operative management or avoidance of laparoscopy when surgery is essential. The effects of this on the investigation and management of appendicitis remain unknown. Methods We performed a multicentre, prospective, observational study from the start of the new guidelines to the 6th of May 2020. We included all patients referred to surgical teams with suspected appendicitis. A recent historical cohort was identified for comparison. The primary outcome was the impact of the COVID-19 pandemic on the use of non-operative management in appendicitis. Secondary outcomes included imaging, negative appendicectomy rate (NAR), length of stay (LOS) and 30-day complications. Results A total of 63/164 (38%) patients compared to 79/191 (41%) were diagnosed with appendicitis before and after the guidelines were introduced (p = 0.589). CT scanning increased (71/164 vs 105/191; p = 0.033) while ultrasound scanning decreased (71/164 vs 62/191; p = 0.037). Appendicitis was more likely to be managed non-operatively (11/63 vs 51/79; p < 0.001) and, of those managed surgically, with an open approach (3/52 vs 26/28 p < 0.001). The NAR also reduced (5/52 vs 0/28; p = 0.157). LOS was shorter in non-operatively managed patients (1 day vs 3 days; p < 0.001) without a difference in complications (10/51 vs 4/28; p = 0.760). Conclusion Introduction of the guidelines was associated with changes in practice. Despite these changes, short-term complications did not increase and LOS decreased. Questions remain on the longer-term complication rates in non-operatively managed patients.

[PMID: 32808480 DOI: 10.1111/ans.16203] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 07/01/2020] [Accepted: 07/09/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND Acute Appendicitis is the most common surgical presentation within Australia. Despite the increasing use of radiological investigations to aid clinical diagnosis, many appendectomies result in a histologically normal appendix. This study examines the histological negative appendicectomy rate (NAR) in a metropolitan hospital and determine factors associated with a negative appendicectomy (NA). METHODS Patients who underwent emergency appendicectomy for suspected acute appendicitis at Logan Hospital, Australia, between February 2016 and March 2019 inclusive were included. Clinicopathologic and imaging variables were analysed for associations with NA. RESULTS A total of 1241 patients underwent emergency appendicectomy of which 121 patients (9.8%) had a NA. The NAR for clinical diagnosis alone (no imaging) was 9.9%, 14.5% for ultrasonography alone and computed tomography scan alone was 4.9%. Univariate analysis revealed age <27 years (P < 0.001), absence of hypertension (P = 0.008), symptoms >48 hours (P < 0.001), absence of leucocytosis (P < 0.001), undergoing ultrasonography only (P < 0.001), undergoing computed tomography scan only (P < 0.001), macroscopically normal appendix (P < 0.001) and time to operation >24 hours (P < 0.001) were associated with NA. Multivariate analysis identified symptoms >48 h at presentation (odds ratio (OR) 1.98, 95% confidence interval (CI) 1.20-3.24; P = 0.007), absence of leucocytosis (OR 2.41, 95% CI 1.52-3.81; P < 0.001) and macroscopically normal appendix (OR 5.70, 95% CI 3.49-9.33; P < 0.001) to be associated with a NA. CONCLUSION The NAR reported is lowest in an Australian institution. The identified predictors of NA will be useful in identifying patients who would truly benefit from an appendicectomy versus those would have a higher rate of NA who may be suitable to be treated non-operatively to be spared the unnecessary morbidity of surgery.

Reducing the negative appendectomy rate with the laparoscopic appendicitis score; a multicenter prospective cohort and validation study. Int J Surg 2020; 79:257-264. [PMID: 32387211 DOI: 10.1016/j.ijsu.2020.04.041] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Revised: 04/05/2020] [Accepted: 04/15/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND Approximately nine percent of all acute appendectomies are unintentionally performed on a normal appendix. Failure of treatment (negative appendectomy or missed appendicitis) is associated with higher morbidity and mortality when compared to appendectomy for uncomplicated appendicitis. The Laparoscopic APPendicitis (LAPP) score was developed in order to systematically evaluate the appendix for the presence of inflammation. This study aims to determine whether the LAPP score reduces the negative appendectomy rate without missing appendicitis. METHODS From September 2013 through May 2016, 322 adult patients presenting with a clinical suspicion of acute appendicitis and an indication for diagnostic laparoscopy were included and analyzed in this multicenter prospective validation study. Depending on the LAPP score, the appendix was either removed (n = 300) or left in situ (n = 22). These patients were compared to a historical control group of 584 patients treated at the same hospitals. The appendix was examined by a pathologist and the negative appendectomy rate was calculated. RESULTS The negative appendectomy rate was significantly lower when the LAPP score was used (4,7% vs. 8,4%; P = 0,034). None of the patients with a negative LAPP score, in which the appendix remained in situ, developed acute appendicitis within three months. There were no significant differences in operation time, complications, or readmissions. Using the LAPP score was associated with significantly higher rates of preoperative radiological imaging (98% vs. 70%; P < 0,001). After adjusting for covariables, including radiological imaging, use of the LAPP score led to fewer treatment failures when compared to not using the LAPP score (OR: 0,48, 95% C.I. 0,251 to 0,914; P = 0,025). CONCLUSION The LAPP score is a safe and simple tool to reduce the negative appendectomy rate during laparoscopic surgery without missing cases of acute appendicitis.

J Pediatr Surg 2020; 55:893-898.

Abstract
PURPOSE The widespread use of laparoscopy has brought forth the question of how to manage a macroscopically normal-appearing appendix in cases of clinically suspected appendicitis. This study aimed to determine the current practices of pediatric general surgeons in Canada regarding this matter. METHODS An online survey was created following the American Pediatric Surgical Association (APSA) guidelines and distributed via email to the Canadian Association of Pediatric Surgeons (CAPS) staff surgeons. The questions assessed clinician characteristics, standard practice, and rationale. Results were analyzed using descriptive statistics. RESULTS A total of 54/72 (75%) CAPS members practicing in Canada completed the survey. All (100%) agreed they would remove a normal-appearing appendix during laparoscopy for suspected acute appendicitis. The most common reasons were: possibility of microscopic appendicitis (39/54, 72.2%), avoiding future diagnostic confusion (28/54, 51.9%), and patient preference/consent discussion (21/54, 38.9%). Most (53/54, 98.1%) had performed a negative appendectomy and 49/54 (90.7%) agreed there were no sufficient guidelines. CONCLUSIONS The majority of pediatric surgeons agree sufficient guidelines do not exist to support decision making when a normal-appearing appendix is found during laparoscopy for suspected acute appendicitis. This survey shows that removal of the appendix in this case would be supported by the majority of Canadian pediatric surgeons. TYPE OF STUDY Survey LEVEL OF EVIDENCE: VII (Expert Opinion).

Abstract
BACKGROUND An objective algorithm for the management of suspected appendicitis guided by the Alvarado Score had previously been proposed. This algorithm was expected to reduce computed tomography (CT) utilization without compromising the negative appendectomy rate. This study attempts to validate the proposed algorithm in a randomized control trial. METHODS A randomized control trial comparing the management of suspected acute appendicitis using the proposed algorithm compared to current best practice, with the rate of CT utilization as the primary outcome of interest. Secondary outcomes included the percentage of missed diagnosis, negative appendectomies, length of stay in days, and overall cost of stay in dollars. RESULTS One hundred sixty patients were randomized. Characteristics such as age, ethnic group, American Society of Anesthesiologist score, white cell count, and symptom duration were similar between the two groups. The overall CT utilization rate of the intervention arm and the usual care arm were similar (93.7% vs 92.5%, p = 0.999). There were no differences in terms of negative appendectomy rate, length of stay, and cost of stay between the intervention arm as compared to the usual care arm (p = 0.926, p = 0.705, and p = 0.886, respectively). Among patients evaluated with CT, 75% (112 out of 149) revealed diagnoses for the presenting symptoms. CONCLUSION The proposed AS-based management algorithm did not reduce the CT utilization rate. Outcomes such as missed diagnoses, negative appendectomy rates, length of stay, and cost of stay were also largely similar. CT utilization was prevalent as 93% of the study cohort was evaluated by CT scan. TRIAL REGISTRATION The study has been registered at ClinicalTrials.gov (NCT03324165, Registered October 27 2017).

Abstract
The epidemiology and the outcomes of acute appendicitis in elderly patients are very different from the younger population. Elderly patients with acute appendicitis showed higher mortality, higher perforation rate, lower diagnostic accuracy, longer delay from symptoms onset and admission, higher postoperative complication rate and higher risk of colonic and appendiceal cancer. The aim of the present work was to investigate age-related factors that could influence a different approach, compared to the 2016 WSES Jerusalem guidelines on general population, in terms of diagnosis and management of elderly patient with acute appendicitis. During the XXIX National Congress of the Italian Society of Surgical Pathophysiology (SIFIPAC) held in Cesena (Italy) in May 2019, in collaboration with the Italian Society of Geriatric Surgery (SICG), the World Society of Emergency Surgery (WSES) and the Italian Society of Emergency Medicine (SIMEU), a panel of experts participated to a Consensus Conference where eight panelists presented a number of statements, which were developed for each of the four topics about diagnosis and management of acute appendicitis in elderly patients, formulated according to the GRADE system. The statements were then voted, eventually modified and finally approved by the participants to the Consensus Conference. The current paper is reporting the definitive guidelines statements on each of the following topics: diagnosis, non-operative management, operative management and antibiotic therapy.

Abstract
The most common surgical emergency is suspected acute appendicitis, the lifetime risk of acute appendicitis is estimated to be 8.6% for men and 6.7% for women, with a male to female ratio of 1.4:1; correct diagnosis can be made in 70–80% of patients after the operations about 32% of appendectomies revealed normal appendices and meanwhile appendectomy has a considerable morbidity and mortality. The aim is to explore potential morbidity and mortality associated with negative appendectomy. Prospective case series study, including 5847 patients, who were suspected to have acute appendicitis over a period of five years from 1st December 2013 to 30th November 2018, in emergency department of Sulaimani Teaching Hospital. All the collected data were collected, organized then analyzed by Statistical Package for the Social Sciences version 21. Morbidity in the patients with negative appendectomies occurred in patients in the form of 90 (01.91%) wound infection, 48 (01.02%) intestinal obstruction and last 15 (00.32%) patients developed septicemia. While mortality in negative appendectomy patients was 21, (00.45%). Negative appendectomies have high rates of morbidity and mortality, knowing real rates may help in considering various policies and may be helpful to elude avoidable complications and potential mortality.

Abstract
BACKGROUND Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. METHODS A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16-45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis). RESULTS Some 5345 patients across 154 UK hospitals were identified, of which two-thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut-off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut-off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent). CONCLUSION Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision-making by identifying adults in the UK at low risk of appendicitis were identified.

Abstract
INTRODUCTION Acute appendicitis is a common surgical emergency, with a prevalence of 112 per 100,000 people per year in Europe. Negative appendicectomy is defined as a pathologically normal appendix removed from patient suspected with appendicitis. Negative appendectomy rate (NAR) has been reported to be around 15-25%. We aimed to evaluate our unit's negative appendectomy rate and the effect of pre-operative imaging on NAR. METHOD A retrospective study including all patients who underwent both open and laparoscopic emergency appendicectomy in a single district general hospital from 2017-2018. Clinical information including cost was calculated based on the 2017/18 national tariff payment system. Patients under 18 years old were excluded from this study. RESULTS Two hundred thirty-two patients were included in this study, of which 69 (29.74%) had a pre-operative CT scan. The mean length of stay was 2.57 days. The sensitivity, specificity, positive predictive value and negative predictive value for CT were 77.8%, 100%, 87.5% and 100%. The negative appendicectomy rate with and without pre-operative CT scan were 7.25% and 22.09% respectively. Based on the 2017/18 national tariff payment system, a CT abdomen and pelvis with contrast and emergency appendicectomy with CC score of 0 cost 92 and 2370 pounds respectively. The total cost of patients who underwent appendicectomy without imaging was £ 322,320. If all patients undergo pre-operative CT, with a reduction of 15% in negative appendicectomy rate, the overall total cost would significantly lower to £ 36,212. CONCLUSION Our study demonstrated that the negative appendicectomy rate could be improved by preoperative imaging. The study also showed that implementation of preoperative imaging for suspected appendicitis cases could save costs, allowing better allocation of resources.

Abstract
Introduction: Acute appendicitis is the most common cause of the abdominal pain in surgery. Despite its significant prevalence, the diagnosis is associated with many problems in some cases, which leads to false appendectomy. Objective: The aim of this study was to determine the validity of diagnostic tests of mean platelet volume (MPV) and red cell distribution width (RDW), as a new possible tool in the diagnosis of acute appendicitis. Methods: In this study, all patients who referred to the emergency department of Besat Hospital, Hamadan, Iran, in 2015, with abdominal pain and first impression of acute appendicitis, undergone appendectomy, were evaluated. The diagnostic markers of pre-operative and post-operative pathology and the validity of MPV and RDW were determined in diagnosis of acute appendicitis. Results: Laboratory and clinical data from 438 patients, presenting the signs and symptoms of acute appendicitis with the mean age of 26.51±13.9 years, were examined (55.6% men). The sensitivity, specificity, positive and negative predictive value of MPV in the diagnosis of acute appendicitis were 59.77, 98.66, 99.5 and 34.26 percent, and for the RDW were 57.79, 56.00, 86.07 and 21.98 percent, respectively. The area under the receiver operating characteristic (ROC) curve for RDW and MPV was 0.61and 0.90, respectively. The mean of MPV in patients with normal pathologic outcome was 9.52±1.60 and in patients with acute appendicitis was 7.51±1.22. There was a significant difference between the mean MPV in both groups (p<0.001). The mean of RDW in patients with normal pathology were 13.42±1.97 and 13.05±1.09, in patients with acute appendicitis. There was a significant difference between the mean RDW of the two groups (p=0.009). Conclusion: MPV and RDW indexes have the potential to be used by the surgeons in diagnosis of acute and perforated appendicitis, especially in adults, in order to reduce unnecessary appendectomy, but MPV is more valid in screening acute appendicitis, compared to the RDW.

Abstract
INTRODUCTION Acute appendicitis is one of the most common causes of abdominal pain in emergency departments worldwide. Despite the improvement in radiological and clinical investigations, negative appendectomy remains a debated topic as well as the optimal strategy for use in cases demonstrating a nonpathological appendix during a procedure for suspected appendicitis. The aim of the present study was thus to analyse clinical outcomes of histologically NA to better elucidate the burden associated with a potentially avoidable procedure. MATERIALS AND METHODS We retrospectively analysed a prospectively collected database of all patients undergoing appendectomy for suspected appendicitis. Patients who underwent an elective appendectomy or an appendectomy for other causes than suspected appendicitis or even an appendectomy during the course of another procedure were excluded from the analysis. RESULTS Data of 627 patients undergoing an emergency procedure for suspected appendectomy were registered. Of the 627 patients, 533 (85%) were found to have acute appendicitis (378 uncomplicated, 155 severe), while the NA rate was 14.9%. A preoperative CT scan was performed in 148 patients (23.6%), an ultrasound evaluation was conducted in 427 patients (68.1%), and 127 patients (20.3%) underwent no imaging prior to surgical intervention. The large majority of procedures was performed laparoscopically (77.7%) and the median procedure duration was 70 min (range 17-270 min). The cumulative conversion rate (both AA and NA) was 5.7%. Leucocytes were significantly lower in cases of NA, while C-reactive protein (CRP) level was found to be increased fourfold in cases of severe versus uncomplicated appendicitis and NA. An increased use of endoloop in appendiceal stump closure was noted in the NA group (88.3% loop vs. 11.7% stapler), while endostapler usage increased in the severe appendicitis group up to 38.1%. Most patients with NA underwent only preoperative ultrasound (71.3%), with just 8.5% of patients in this group having a CT scan before surgery. Ultrasound sensivity was 0.648 and specificity was 0.438. For CT scan, sensivity was 0.949 and specificity was 0.625. LOS in the NA patient group was comparable to that of patients affected by uncomplicated appendicitis, while patients with severe appendicitis experienced a 2-day-longer median recovery. Complications were significantly higher in the severe appendicitis group but comparable in the other two groups. Surgical site infections were the most frequently reported complications. CONCLUSIONS Young women are particularly at risk for NA. Increasing the use of preoperative CT and incorporating imaging into the overall assessment of a patient seems to be actually the only way to reduce the incidence of NA without increasing the rates of perforation. Considering the relatively high morbidity after an NA procedure, every surgeon must carefully consider the risk-benefit balance prior to performing an appendectomy during diagnostic laparoscopy for suspected acute appendicitis showing a macroscopically noninflamed appendix.

Readmission and reoperation rates following negative diagnostic laparoscopy for clinically suspected appendicitis: The "normal" appendix should not be removed - A retrospective cohort study. Int J Surg 2019; 64:1-4. [PMID: 30769215 DOI: 10.1016/j.ijsu.2019.02.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Revised: 01/30/2019] [Accepted: 02/04/2019] [Indexed: 02/09/2023]
Abstract
BACKGROUND In cases with clinically suspected appendicitis, there is controversy regarding the decision to remove a macroscopically normal appearing appendix during laparoscopy when no other intra-abdominal pathology is found. The aim of this study was to examine the rate of appendicitis, along with readmission and reoperation rates following diagnostic laparoscopy of clinically suspected appendicitis in patients where the appendix was not removed. METHODS We performed a retrospective cohort analysis of patients who underwent a diagnostic laparoscopy due to clinical suspicion of appendicitis where no other pathology was found and the appendix was not removed. The study period was from 2008 to 2013 and involved patients from two university hospitals in the Copenhagen area. RESULTS Of the 271 patients included (81.6% women, median age 27), 56 (20.7%) were readmitted with right iliac fossa pain after a median time of 10 months (range 1-84). Twenty-two patients (8.1%) underwent a new laparoscopic procedure. Appendix was removed in 18 patients, of which only one showed histological signs of inflammation. The median follow-up time was 5.6 years (range 1-109 months). CONCLUSION There was a low rate of appendicitis after a previous negative diagnostic laparoscopy. Therefore, based on results from the current study, we do not consider that it is necessary to remove a macroscopic normal appendix during laparoscopy for clinically suspected appendicitis. The high readmission rate warrants the need for further investigation or follow-up.

Abstract
PURPOSE Acute appendicitis (AA) is the most frequent surgical entity in the emergency department, but its correct diagnosis remains challenging. To improve diagnosis, clinical prediction rules (CPRs) have been created to establish objective scores for the probability of suffering AA. In this study, we establish scores indicating whether laparoscopy would be superior to clinical observation or repeat diagnostic test. METHODS A retrospective observational study was conducted with 433 patients submitted to surgery for suspected AA using a laparoscopic approach. The Alvarado, Raja Isteri Pengiran Anak Saleha Appendicitis, appendicitis inflammatory response, and adult appendicitis score scales were applied in each case to establish a high, medium, or low probability of suffering AA. RESULTS Of the 433 patients analyzed, 381 (88.0%) had AA. Twelve (2.8%) were converted to open surgery, and complications were observed in 54 (12.5%) cases. The CPRs studied showed statistically significant differences between AA and negative appendectomies. However, in patients with intermediate probability scores, the diagnostic accuracy of the CPRs evaluated was not adequate. CONCLUSIONS Laparoscopic surgery can serve as a diagnostic tool for patients with intermediate AA probability scores because of its low associated morbidity and mortality and because it affords a direct diagnosis of the problem, allowing determination of the appropriate treatment.

Abstract
SUMMARY – Laparoscopic appendectomy is the method of choice of many professional societies owing to its many advantages. The question arises whether surgeons urge more easily to laparoscopic exploration due to its less invasiveness, faster recovery and adequate exploration of the entire abdominal cavity than to observation in unequivocal cases. This retrospective analysis (2009-2016) included 1899 patients undergoing laparoscopic (lap) or gridiron intra-abdominal approach treated at Zagreb University Hospital Centre. The analysis included total negative appendectomy, negative-negative appendectomy (normal appendix and no other pathology found), and negative-positive appendectomy (normal appendix but another pathology found) in children (≤16 years) and adults. There was no statistically significant difference in the rates of negative appendectomy (children) – lap vs. open (p=0.24); negative appendectomy (adults) – lap vs. open (p=0.15); negative-negative appendectomy (children) – lap vs. open (p=0.36); negative-negative appendectomy (adults) – lap vs. open (p=0.21); negative-positive appendectomy (children) – lap vs. open (p=0.53); negative-positive appendectomy (adults) – lap vs. open (p=0.56); and laparoscopy group negative appendectomy in children vs. adults (p=0.56). There was a statistically significantly higher perforation rate with the open approach in total (p<0.0001), in children (p<0.0001) and in adults (p=0.02). There was no statistically significant difference between adults and children in the perforation rate with laparoscopic approach (p=0.24) and perforation rate with open approach (p=0.29). Results confirmed that there was no statistically significant difference in the rate of negative appendectomy in all subgroups. It is concluded that laparoscopic appendectomy should be offered as the method of choice in any patient population with suspicion of acute appendicitis.

Abstract
BACKGROUND The aim of this study was to determine the frequency and indications for unplanned readmission and outpatient examination after acute appendectomy. METHODS Adults who underwent acute appendectomy from 2008-2013 were included in the study and events occurring within 90-days from discharge recorded. RESULTS A total of 710 patients underwent surgery. The appendix was removed in 622 patients and post-discharge contact occurred in 99 (15.9%): readmission in 60 (9.6%), outpatient examination in 39 (6.3%). The main reasons for post-discharge contact were infection (n = 25; intraabdominal, n = 16; superficial) and abdominal pain of uncertain cause (n = 25). Use of prophylactic antibiotics was associated with lower rates of contact, 8.5% versus 20.9% (p = 0.006), respectively. Removal of non-inflamed appendix was borderline associated with higher rates of contact, 21.7% versus 8.0% (if left in-situ; p = 0.058), respectively. CONCLUSIONS A substantial number of patients underwent readmission or outpatient examination within 90-days after appendectomy in the current study. The procedure is common and attempts to prevent readmissions are important. Correct use of antibiotics and not removing a non-inflamed appendix may be key points.

Abstract
PURPOSE Acute appendicitis is the most frequent emergency procedure that requires acute surgical intervention. The mortality risk is higher in geriatric patients. There is not a single parameter to diagnose it easily and negative appendectomy is traditionally accepted however the operation itself can cause morbidity and mortality especially in elderly patients. The neutrophil-to-lymphocyte ratio is a predictor of acute inflammation and was recently studied for the diagnosis of AA. The aim of this study is to analyze the diagnostic value of NLR on positive appendectomy rates amongst geriatric and nongeriatric patients. MATERIALS AND METHODS 755 patients admitted to the emergency department, with abdominal pain who underwent urgent laparotomy after diagnosed as acute appendicitis. Patients' ages, genders, laboratory results, and intraoperative findings were collected. Geriatric patients were analyzed in group one, and nongeriatric patients were in group 2. Groups then sorted into subgroups by means of positive and negative appendectomies. RESULTS Although NLR was higher in positive appendectomy subgroup in group 1 it was not statistically significant. NLR could not independently predict positive appendectomy in geriatric patients. In group 2, male gender was significantly higher in the positive appendectomy group (p < 0.001). NLR was also significantly higher in the positive appendectomy group (p < 0.001). In group 2 NLR could independently predict positive appendectomy (p < 0.001). CONCLUSION NLR could not predict positive appendectomy rates in the geriatric population but could in the nongeriatric patient group. To find the optimal NLR levels, prospective randomized studies are needed.

Abstract
Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

Delaying surgery to perform CT scans for suspected appendicitis decreases the rate of negative appendectomies without increasing the rate of perforation nor postoperative complications. Langenbecks Arch Surg 2016; 401:643-9. [PMID: 27146319 DOI: 10.1007/s00423-016-1444-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Accepted: 04/27/2016] [Indexed: 12/29/2022]
Abstract
PURPOSE Negative appendectomies are costly and are embedded with unnecessary risks for the patients. A careful indication for surgery seems mandatory even more so, since conservative therapy emerges as a potential alternative to surgery. The aims of this population-based study were to analyze whether radiological examinations for suspected appendicitis decreased the rate of negative appendectomies without increasing the rate of perforation or worsening postoperative outcomes. METHOD This study is a retrospective analysis of a prospective population-based database. The data collection included preoperative investigations and intraoperative and postoperative outcomes. RESULTS Based on 2559 patients, the rate of negative appendectomies decreased significantly with the use of CT scan as compared to clinical evaluation only (9.3 vs 5 %, p = 0.019), whereas ultrasonography alone was not able to decrease this rate (9.3 vs 6.2 %, p = 0.074). Delaying surgery for radiological investigation did not increase the rate of perforation (18.1 vs 19.2 %; adjusted odds ratio (OR) 1.01; 0.8-1.3; p = 0.899). Postoperative complications (surgical reintervention, postoperative wound infection, postoperative hematoma, postoperative intra-abdominal abscess, postoperative ileus) were all comparable. CONCLUSION In this population-based study, CT scan was the only radiological modality that significantly reduced the rate of negative appendectomy. The delay induced by such additional imaging did not increase perforation nor complication rates. Abdominal CT scans for suspected appendicitis should therefore be more frequently used if clinical findings are unconclusive.

Abstract
BACKGROUND Acute appendicitis is a principal cause of abdominal pain worldwide and most common in young men who constitute the majority of the deployed fighting force. Diagnostic accuracy is paramount to prevent unnecessary intervention, morbidity and force impact. METHOD A consecutive series of appendicectomies, performed over 28 months on deployment in Afghanistan, was evaluated to assess the negative appendicectomy (NA) rate, explore the impact of CT on the rates of NA and assess the impact of appendicectomy on manpower in the deployed workforce. RESULTS In Afghanistan, the operative NA rate was 9.6%, whereas the histological NA rate was 20.5%. CT was widely used in Afghanistan (36%) and there was a significant reduction in NA rates if CT was performed preoperatively (6.25% vs 26%, p=0.02). CONCLUSIONS Diagnostic imaging will be limited in future conflicts and reliance on clinical judgement will be necessary. Military clinicians may need to accept higher rates of NA, as prolonged observation may not be possible. CT scanning should be used to a greater extent when available. A conservative management strategy for appendicitis with appropriate antibiotics should be considered in the event of delayed transfer to a surgical facility.

Abstract
INTRODUCTION Acute appendicitis represents the commonest cause of acute intra-abdominal pathology. Appendectomy and antibiotics are the mainstay of therapy for appendicitis. Evidence is emerging that antibiotics alone may adequately treat most cases of appendicitis. Decision analysis is a quantitative method of examining alternate treatment strategies. This study describes a modelled decision analysis comparing operative and conservative management of appendicitis. METHODS The base case patient is a healthy, 23-year-old male presenting with migratory pain to the right iliac fossa (RIF) and elevated inflammatory markers. A decision tree was constructed comparing operative and conservative treatment. Rates of complications, failure of conservative therapy, recurrence and utilities were calculated via a systematic literature review. Variables were tested for sensitivity. RESULTS Overall, conservative management gives a significantly better outcome (51.51 vs 49.87 QALYs). Three variables proved sensitive. Once operative complication rates are lower than 11.5 %, surgical treatment becomes the optimal strategy. If rates of failure of conservative management exceed 12.9 %, surgery becomes optimal. If the utility assigned to a post-operative complication exceeds 0.44, surgery becomes optimal. CONCLUSIONS This decision analysis supports a conservative strategy, albeit with caveats. If operative complications are low or rates of failure of conservative management remain high, surgery is the preferable strategy.
