Amyand’s hernia is a hernia where the appendix is within the inguinal hernial sac. It is often diagnosed by chance due its indeterminate clinical presentation. This case reports a 50-year-old Filipino male who presented with direct and rebound tenderness on the lower abdomen in the presence of a right inguinal bulge. CT scan showed an appendix coursing inferiorly into the pelvis, herniating through a 2 cm defect of the anterior abdominal muscle into the right inguinal region along with mesenteric fat. Laparoscopy confirmed acute appendicitis within an inguinal hernia (Amyand’s hernia Type 2). Diagnostic laparoscopy, appendectomy and primary repair of the right inguinal ring were performed. The patient had an unremarkable post-operative course and was discharged after 2 days. He was advised to undergo IPOM to prevent hernia recurrence. Laparoscopic management can be a safe option for cases of Amyand’s hernia.

INTRODUCTION: This study aimed to investigate the ultrasonographic features of paediatric acute appendicitis and incorporate them into a scoring algorithm that will quantify the risk of complications and the strength of recommendation for surgical intervention. METHODS: 179 patients with suspected appendicitis who had undergone ultrasonographic examination were included in this study. Based on their medical evaluation and post-surgical histopathological results, patients were categorised into confirmed appendicitis (n = 101) and non-appendicitis (n = 78) groups. RESULTS: In the appendicitis group, the appendix was visualised in 66 (65.3%) patients. In cases where the appendix was not visualised, we looked out for secondary inflammatory signs, which were present in 32 (31.7%) patients. Using stepwise logistic regression, Blumberg's sign, free fluid or collection, hyperaemia, non-compressible appendix and an appendix diameter > 7 mm were found to be significant predictive factors for appendicitis. A new scoring system called POPs was developed, combining inflammatory predictors and ultrasonography findings, with an area under the receiver operating characteristic curve of 0.958 (95% confidence interval 0.929-0.986). CONCLUSION The newly developed POPs-based diagnosis scheme proved a promising alternative to existing scoring systems such as the Alvarado score. Although further calibration would be beneficial, the proposed scoring scheme is simple and easy to understand, memorise and apply in the emergency room.

OBJECTIVES: To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain. METHODS: A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate. RESULTS: Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×10⁹/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%). CONCLUSIONS Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

Background: Tiered services, differentiated by the financial capacity of patients and related payment arrangements with hospitals, are the norm in Philippine facilities. This study considered how these, together with selected demographic and clinical factors, were associated with surgical care utilization, provision, and outcomes for patients with appendicitis in a public university hospital.

Methods: This was a retrospective cohort study, utilizing data obtained from an electronic patient registry. Patients who underwent emergent appendectomies from January 2017 to December 2018 were included. Data were analyzed using multivariate and logistic regression, with the following dependent variables: time from symptom onset to emergency department consultation (ED Lag), time from consult to surgery (OR Lag), selection for laparoscopic appendectomy (LA), the occurrence of complicated appendicitis (CA), and length of stay (LOS). Morbidities and mortalities were tallied.

Results: There were 1,501 patients included in the study. Young adult males comprised the majority and mostly had non-private accommodations. Non-CA was the impression in more than 80% of cases. Extremes of age were associated with longer ED and OR Lags, greater likelihood of CA, and longer LOS. Patients initially assessed as having CA had shorter OR Lags, were less likely to undergo LA, and had longer LOS. Private patients were more likely to have undergone LA, lower CA odds, and slightly longer LOS.

Conclusions: Variations in surgical care utilization, provision, and outcomes for patients with appendicitis were independently associated with socioeconomic and clinical status differences.

Inferior vena cava agenesis (IVCA) is an uncommon congenital anomaly which was first described in the seventeenth century. The detection of such an anomaly is often incidental and patients are asymptomatic until the third to fourth decade of life. Due to the scarcity of these cases, there is no consensus on the subsequent treatment and surveillance of incidental asymptomatic IVC anomalies. Herein, we report on a young male with incidental findings of suprarenal IVC agenesis identified on contrast enhanced computed tomography (CT) scan of the abdomen in the course of treatment for acute appendicitis.

appendicitis.MATERIALS AND METHODS: An ethical committee approved this prospective study. We introduced 2-mSv CT in 20 hospitals through a pragmatic clinical trial. At the final phase of the trial, we invited 698 potentially-involved care providers in the survey regarding their willingness to use 2-mSv CT. Multivariable logistic regression analyses were performed to identify factors associated with willingness. Nine months after the completion of the trial patient recruitment, we surveyed whether the hospitals were using 2-mSv CT in usual practice.RESULTS: The analyses included responses from 579 participants (203 attendings and 376 trainees; 221 radiologists, 196 emergency physicians, and 162 surgeons). Regarding the willingness to immediately change their standard practice to 2-mSv CT, 158 (27.3%), 375 (64.8%), and 46 (7.9%) participants responded as “yes” (consistently), “partly” (selectively), and “no”, respectively. Willingness varied considerably across the hospitals, but only slightly across the participants' departments or job titles. Willingness was significantly associated with attendings (p = 0.004), intention to maintain the dedicated appendiceal CT protocol (p < 0.001), belief in compelling evidence on the carcinogenic risk of conventional-dose CT radiation (p = 0.028), and hospitals having more than 1000 beds (p = 0.031). Fourteen of the 20 hospitals kept using 2-mSv appendiceal CT in usual practice after the trial.CONCLUSION: Despite the extensive efforts over the years of this clinical trial, many care providers were willing to use 2-mSv CT selectively or not willing to use.]]>

OBJECTIVES: Ultrasound has an established role in the diagnostic pathway for children with suspected appendicitis. Relevant clinical information can influence the diagnostic probability and reporting of ultrasound findings. A Bayesian network (BN) is a directed acyclic graph (DAG) representing variables as nodes connected by directional arrows permitting visualisation of their relationships. This research developed a BN model with ultrasonographic and clinical variables to predict acute appendicitis in children. METHODS: A DAG was designed through a hybrid method based on expert opinion and a review of literature to define the model structure; and the discretisation and weighting of identified variables were calculated using principal components analysis, which also informed the conditional probability table of nodes. RESULTS: The acute appendicitis target node was designated as an outcome of interest influenced by four sub-models, including Ultrasound Index, Clinical History, Physical Assessment, and Diagnostic Tests. These sub-models included four sonographic, three blood-test, and six clinical variables. The BN was scenario tested and evaluated for face, predictive, and content validity. A lack of similar networks complicated concurrent and convergent validity evaluation. CONCLUSIONS: To our knowledge, this is the first BN model developed for the identification of acute appendicitis incorporating imaging variables. It has particular benefit for cases in which variables are missing because prior probabilities are built into corresponding nodes. It will be of use to clinicians involved in ultrasound examination of children with suspected appendicitis, as well as their treating clinicians. Prospective evaluation and development of an online tool will permit validation and refinement of the BN.

PURPOSE: The purpose of this study was to determine whether the awareness and inclusion of secondary sonographic signs of appendicitis, in combination with a structured evaluation as part of engagement and training for sonographers, improved appendix visualization rates and reduced equivocal findings in children with suspected acute appendicitis. METHODS: This was a prospective study of 230 children at a tertiary children's hospital in Australia referred for an ultrasound examination of suspected appendicitis. The ultrasound findings, radiology reports, histology, clinical results, and follow-up were collated. Secondary signs were used as an additional assessment of the likelihood of disease where possible, even in the absence of an identified appendix. RESULTS: The implementation of a structured evaluation as part of sonographer engagement and training resulted in a 28% improvement in appendix visualization (68.7%) compared with a prior retrospective study in a similar population (40.7%). The diagnostic accuracy was 91.7%, with likelihood ratios suggesting a meaningful influence of the pre-test probability of appendicitis in children studied (positive likelihood ratio, 11.22; negative likelihood ratio, 0.09.). Only 7.8% of the findings were equivocal. A binary 6-mm diameter cut-off did not account for equivocal cases, particularly lymphoid hyperplasia. CONCLUSION: Engagement of sonographers performing pediatric appendiceal ultrasound through training in the scanning technique and awareness of secondary signs significantly improved the visualization rate and provided more meaningful findings to referrers.

Acute appendicitis is the most common indication for emergency abdominal surgery worldwide. The risks and benefits of incidental appendectomy during other operations have been debated for over a century. There is no right answer to the question of whether or not to perform incidental appendectomy. Although there are only a few indications where it is explicitly recommended such as in gynecological surgery, malrotation, and Ladd's procedure, incidental appendectomy is cost-effective in selected patient groups, especially in the young, without an increase in morbidity and mortality. In this review, the literature on incidental appendectomy was assessed from several perspectives.
