Nephroptosis and ureteroinguinal incarcerated hernia mimicking acute appendicitis

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.

Validate the Precision of the RIPASA Grading System for the Diagnosis of Acute Appendicitis: A Cross-Sectional Study

Aim: To determine the accuracy of the RIPASA (Raja Isteri Pengiran Anak Saleha Appendicitis) grading system for the diagnosis of acute appendicitis. Study design: A cross-sectional study Place and Duration: This study was conducted at Jinnah Postgraduate Medical Centre Karachi Pakistan from March 2020 to November 2021. Methodology: A total of 150 patients with clinical signs of acute appendicitis were studied. To determine the RIPASA score's validity, testing was assessed for acute appendicitis. Patients with gynecological and urological disorders, appendicular lumps, were excluded from the study. The RIPASA Score chart was employed, and the findings of additional clinical studies corroborated the findings. Results: Among the 150 patients, 80 (53.3%) were males, and 70 (46.66%) were females. The participants' average age was 22 ± 5.4 years. At a cut-off score of 7.5, the RIPASA scoring system exhibited good validation testing. The majority of the population (n=135, 90 %) was under the age of 40, with the minority (n=15, 10%) being over 40. The incidence of appendicitis increases dramatically in the second and third decades. There is no case below the age of ten and no case over the age of sixty years. Conclusion: For the diagnosis of AA, the RIPASA score is more sensitive and specific. This Scoring system is a valid and significant selective power in the diagnosis of appendicitis and in reducing unnecessary admissions and abdominal explorations, especially in the Asian race.

The Diagnostic Role of Hyperbilirubinemia in Complicated and Non -complicated Appendicitis

Background: Acute appendicitis is one of the most frequent causes of abdominal pain. Early diagnosis is the key to success for the surgeon, followed by the treatment with operation or conservative treatment as a new approach, before the stage of gangrenous appendicitis or perforation occurs.Aim: This study aims to establish he role of hyperbilirubinemia as a laboratory marker in prediction of acute appendicitis in the early diagnosis.Materials and methods: This is a cross-sectional study; it included 201 patients admitted in the emergency ward with suspicion for acute appendicitis. All patients that participated in this study have been subject to appendectomy. The blood samples were taken from all patients in order to analyze the level of total/direct bilirubin.Results: The study samples of 201 patients consisted of 67.7% with complicated appendicitis and 32.3% with non-complicated appendicitis. The sensitivity, specificity, PPV, NPV for laboratory marker, as predictor for complicated vs non-complicated cases of appendicitis was as follows: Total bilirubin; specificity (72.3%), sensitivity (54.4%), PPV (80.4%), NPV (43.1%),Conclusion: Elevation of total/direct bilirubin level in patients with clinical signs of acute appendicitis might predict the stage of acute appendicitis, such prediction may help surgeons to provide accurate treatment of the disease without delay in the diagnosis. This accuracy can be further supplemented by using Alvarado scoring model during the clinical approach.

First-in-human preliminary pharmacokinetic data on a novel recombinant acid α-glucosidase, ATB200, co-administered with the pharmacological chaperone, AT2221, in patients with late-onset Pompe disease

Almost any anatomical compartment may be involved in Gaucher disease (GD). Abdominal lymphadenopathy occurred during enzyme replacement therapy in more than a dozen children with GD so far. A fourteen-year-old boy from Serbia developed clinical signs of acute appendicitis six years after the onset of GD type 3 related abdominal lymphadenopathy. Ultrasound examination showed diffuse thickening of the intestinal wall in the ileocoecal region with periappendicular infiltration. An appendectomy was performed four months after conservative treatment with antibiotics. Histopathology revealed macrophages with cytological characteristics of Gaucher cells densely crammed in mesoappendiceal adipose tissue. Also the multifocal replacement of subserosal tissue by Gaucher cells and their infiltration to a variable depth of muscularis propria of the appendix were verified. Frank infiltration of the vermiform appendix with Gaucher cells represents a novel observation in a wide spectrum of manifestations reported in GD. A possible causative relationship of this infiltration with appendicitis is considered.

Nonsurgical Management of Acute Uncomplicated Appendicitis in Children: the Analysis of Treatment Outcome in Relationship with Antimicrobial Regimens and Adverse Prognostic Factors

Summary Introduction. For acute appendicitis - the most frequent condition to perform an urgent abdominal operation in pediatric surgery - surgical appendectomy still remains the gold standard regarding treatment, nevertheless nonsurgical management has become more and more recognized as a treatment method for uncomplicated acute appendicitis (UAA). However there are still many unanswered questions regarding possible factors that could predict the treatment outcome as well as appropriate antimicrobial drug regimens. Aim of the Study. The aim was to investigate if there is a possible association between factors such as C-reactive protein (CRP) level, presence of appendicolith, the diameter of the appendix and treatment outcome; as well as to identify most successfully used antimicrobial drug combinations. Material and methods. A retrospective analysis of hospital cases, admitted to a single reference center during the time period from 2013 to 2015. Patients with clinical signs of acute appendicitis, elevated inflammatory markers and radiological findings suggestive for acute appendicitis were included in the study. Nonsurgical treated patients were divided in two groups based on the treatment outcome - successful or unsuccessful. Analysis of the three factors (CRP level, presence of appendicolith and the diameter of the appendix) and most commonly used antimicrobial drug regimen association with treatment outcome was performed. Results. Overall 384 children medical records with acute appendicitis were registered and non-surgical treatment was initiated in 147/384 (38 %) cases. Successful treatment outcome of nonsurgical management was identified in 114/147 (78 %) cases. Analyzing prognostic adverse factors results presents no statistically significant difference in association with CRP level >25 mg/l (p=0,479), presence of appendicolith (p=0,183) and the diameter of appendix >1 cm (p=0,183) with successful or unsuccessful treatment outcome. The two most commonly used antimicrobial drug combinations were - Ampicillin/Metronidazole for 49 patients and Ampicillin/Gentamicin for 44 patients. No relevance with treatment outcome and used antimicrobial agents was detected (p=0,597). The overall recurrence rate after initial presentation is 15 % (17/114). In 3 cases (3 %) recurrent appendicitis developed one month after discharge and in 14 cases (12 %) up to one year after discharge. Conclusions. Prognostic adverse factors - CRP, presence of appendicolith and diameter of appendix - were not statistically reliable in association with initial non-surgical treatment outcome. The success rate of conservative treatment with narrow spectrum antibiotics was 78 %, which is just as high as in cases treated conservatively with broad-spectrum antibiotics from previous studies. Therefore the question of which factors and antimicrobial drug combinations influence the course of treatment still remains unanswered and further studies are required.

Appendiceal involvement in a patient with Gaucher disease

Almost any anatomical compartment may be involved in Gaucher disease (GD). Abdominal lymphadenopathy occurred during enzyme replacement therapy in more than a dozen children with GD so far.

Apendicitis epiploica. Informe de un caso y revisión de la literatura

La apendicitis epiploica es una consecuencia de la torsión o trombosis espontánea de las venas de drenaje de los apéndices epiploicos en la serosa del colon. Esta afección puede simular múltiples procesos de abdomen agudo quirúrgico. Es una entidad extremadamente rara en edad pediátrica. Se describe el caso de un escolar de diez años de edad con datos clínicos sugestivos de apendicitis aguda, que fue sometido a una inter- vención quirúrgica, durante la cual se hallaron prolongaciones de la grasa normal del colon, pedunculadas, adheridas a la serosa del ciego, que requirieron disección y resección; además se realizó una apendicectomía profiláctica. El paciente evolucionó favorablemente. Palabras clave: Apendicitis epiploica, abdomen agudo, tomografía computarizada, apendicectomía.

Solitary cecal diverticulitis: an unusual cause of acute right iliac fossa pain-a case report and review of the literature.

Solitary cecal diverticulitis is a rare cause of acute abdominal pain in the Western world. Its clinical presentation, in most cases, mimics acute appendicitis. A 38-year-old Caucasian man presented with acute abdomen and clinical signs of acute appendicitis. Laparotomy was performed and revealed an inflammatory, solitary diverticulum of the cecum. A typical appendectomy was performed and a catheter was inserted for draining percutaneously the inflamed diverticulum of the cecum. The patient had an uneventful recovery and was discharged on the 4th postoperative day. This frequently misdiagnosed condition, in most cases, is being suspected and identified intraoperatively as acute appendicitis. The aim of this study is to review the available different surgical management options and to present an alternative therapeutic approach that may be valuable under specific circumstances.

ACR Appropriateness Criteria® Right Lower Quadrant Pain—Suspected Appendicitis

The diagnostic imaging of patients presenting with right lower quadrant pain and suspected appendicitis may be organized according to age and gender and to the presence or absence of "classic" signs and symptoms of acute appendicitis. Among adult patients presenting with clinical signs of acute appendicitis, the sensitivity and specificity of CT are greater than those of ultrasound, with improved performance when CT is performed with intravenous contrast. The use of rectal contrast has been associated with decreased time in the emergency department. Computed tomography has also been shown to reduce cost and negative appendectomy rates. Both CT and ultrasound are also effective in the identification of causes of right lower quadrant pain unrelated to appendicitis. Among pediatric patients, the sensitivity and specificity of graded-compression ultrasound can approach those of CT, without the use of ionizing radiation. Performing MRI after inconclusive ultrasound in pregnant patients has been associated with sensitivity and specificity of 80% to 86% and 97% to 99%, respectively. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Acute appendicitis and carcinoid tumor in Meckel’s diverticulum. Three pathologies in one: a case report

Incidental carcinoid tumor of the Meckel's diverticulum is an uncommon event. Herein, a case of a carcinoid tumor in Meckel's diverticulum that was incidentally found in a patient with acute appendicitis is presented. A 42-year-old Caucasian man presented with acute abdomen and clinical signs of acute appendicitis. A typical appendectomy was performed during which further abdominal exploration revealed a Meckel's diverticulum 60 cm proximal to the ileocecal valve, with an irregular and somewhat indurated serosal region on one side. A stapled diverticulectomy was performed. Pathology revealed an incidental carcinoid tumor measuring 1 cm within the Meckel's diverticulum. CT scan of the abdomen and 24-h urine 5-hydroxyindoleacetic acid results were normal. The patient had an uneventful recovery and was discharged at the 5th postoperative day. He is alive and without evidence of disease 23 months after the operation. Coexistence of acute appendicitis along with an incidental Meckel's diverticulum raises controversies in their surgical management. We discuss the issues in managing patients with two or more of these coexistent pathologies.

Akute Appendizitis im Kindesalter: Korrelation klinischer und histopathologischer Befunde

Quantifying the histopathological diagnoses of appendectomies in daily routine paidopathology results in a high percentage of appendices without histomorphological sign of acute inflammation. To identify clinical factors significantly associated with the morphological diagnosis, histopathological findings and clinical data--documented in patients' files--were examined. All 856 children (age: 5 m-15 yrs) whose appendix had been resected within a 7-year-period were--depending on the histopathological diagnoses--allocated to the group "appendix without" resp. "appendix with signs of acute inflammation". All files were examined concerning anamnestic data, clinical signs of acute appendicitis and laboratory parameters. The data were analysed by χ(2)-test and Wilcoxon-test concerning differences between the 2 groups with regard to the anamnestic and clinical facts and parameters. Using binary logistic regression, these clinical parameters were analyzed in correlation with the histopathological diagnoses. By consideration of the factors "leucocyte count", "vomiting" and "percussion tenderness" 75% of the children would have been allocated to the accurate postoperative pathomorphological diagnosis. There was a significant correlation of "leucocyte count", "vomiting" and "percussion tenderness" with histopathology in 75% of the children. As hence 25% were not allocated correctly this combination is no unequivocal combination for prediction or exclusion of an acute appendicitis. Hence, even with these statistically significant parameters a comparably high percentage of falsely-positive appendectomies has to be anticipated.

Cytochemical and immunocytochemical characteristics of Meckel's diverticulum with heterotopic rests of pancreatic tissue

Meckel's diverticulum (MD) is a congenital anomaly of the small intestine. It results from incomplete obliteration and resorption of the proximal omphaloenteric duct connecting yolk sac with primitive gut in the fetal period. A case of 20-year old female with ectopic pancreatic rests in a MD was reported. She was hospitalized with clinical signs of acute appendicitis. During surgery an inflamated Meckel's diverticulum was found and a clinoid resection of the diverticulum was performed. Histologic examination revealed pancreatic tissue in the removed diverticulum. Endocrine cells (EC) were detected with Masson staining and aberrant pancreatic tissue with immunocytochemical LSAB2 method using pan cytokeratin as epithelial marker. Most of MD are asymptomatic and accessory finding during laparothomias for different causes, but complications of undiagnozed MD can be serious (diverticulitis, perforation with peritonitis or intestinal obstruction caused by invagination). In unclear cases, additional cytochemical and immunocytochemical diagnostics could be done.

Leukocytes, C-Reactive Protein and Interleukin-6 in Acute Appendicitis in Children: Diagnostic Value and Association with Histological Findings

Background: Many efforts have been made to find diagnostic tools that would help select children with clinical signs of acute appendicitis that would need immediate appendectomy and to find tools that would reduce the numbers of negative appendectomies. Aim: We aimed to show the association between leukocyte count, level of C-reactive protein and interleukin-6 in peripheral blood on the one side and the degree of histological findings on appendix after appendectomy on the other side in children with high clinical probability for appendicitis (Alvarado score>7). Methods: We analyzed 80 patients of both genders, younger than 15 years, with Alvarado score>7, which underwent open appendectomy with subsequent histological analysis of removed appendices. We sampled 20 consecutive cases without signs of inflammation (group I), 20 cases with pathological signs of incipient inflammation (group II), 20 cases with signs of phlegmonous inflammation (group III) and 20 cases with signs of perforated appendix (group IV). Prior to appendectomy, a peripheral blood was sampled and sent for analysis of leukocyte count and C-reactive protein and interleukine-6 level. We compared values of all 3 measured parameters according to histological findings; we also used Receiver Operating Characteristics (ROC) analysis in order to evaluate diagnostic thresholds for detecting the histological signs of appendicitis. Results: The lowest values of all observed parameters were found in group of negative appendicitis while highest were observed in the group of perforated appendicitis. We have observed a significant between group differences in values of all three parameters according to the degree of histological inflammation (p<0.001). ROC analysis demonstrated that interleukine-6 had the best diagnostic performance in detecting patients with histological signs of appendicitis (AUROC=0.99; 95% CI=0.99-1.00) when compared to CRP and leukocyte count (p<0.05). There was no significant difference in diagnostic performance between CRP and leukocytes counts (p=0.35). Conclusion: Leukocyte count, CRP and interleukine-6 are very useful markers which may help in diagnostics and differentiation of phlegmonous and perforated appendicitis. In patients with high probability of appendicitis, measurement of interleukine-6 may help in better patient selection.

Torsion of parietal-peritoneal fat mimicking acute appendicitis: a case report

IntroductionInfarctions of the greater omentum and appendices epiploicae are uncommon, but well documented causes of acute abdominal pain. We present a rare case of torted fat on the parietal peritoneum over the anterior abdominal wall, mimicking clinical signs of acute appendicitis, which was diagnosed at laparoscopy. We are aware of only two other similar reported cases, both of which were diagnosed at the time of laparotomy.Case presentationA 41-year-old Caucasian woman presented with clinical signs of acute appendicitis. On diagnostic laparoscopy, a non-inflamed appendix was found. Further exploration revealed a necrotic torted appendage of fat overlying the parietal peritoneum of the right iliac fossa of the anterior abdominal wall.ConclusionTorted fatty appendages can be a diagnostic dilemma often mimicking more common causes of an acute abdomen. Laparoscopy is an excellent tool making the correct diagnosis in such cases.

Significance of intraepithelial lymphocytes in appendix

The aim of this study was to investigate the importance of the increase in intraepithelial lymphocytes (IELs) in the mucosa of the appendix. One hundred and four retrospective appendectomy specimens were examined to evaluate the IELs. Intraepithelial lymphocytosis was identified in 11.5% (12 cases) of the specimens. Of these 12 cases, 6 cases with intraepithelial lymphocytosis were associated with parasitic infection. No increase in IELs was found in the 36 appendices that were removed in other primary operations. A wide range of immunologic stimuli can raise IELs in the gastrointestinal system. However, in appendectomies with clinical signs of acute appendicitis, an increase in IELs is more likely to be related to parasitic infection. This increase should be considered for the diagnosis of parasitic infections.

Delayed diagnosis of appendicitis in children treated with antibiotics

The diagnosis of appendicitis in children can be difficult. Misdiagnosis may result in empirical treatment with antibiotics. The aim of this study was to determine whether initial treatment with antibiotics hindered subsequent diagnosis of appendicitis. Retrospective review of 311 children treated for appendicitis between 1999 and 2004. Patients were divided into two groups: Group 1: (n = 45) received antibiotics prior to a definitive diagnosis of appendicitis. Group 2: (n = 266) did not receive antibiotics prior to a diagnosis of appendicitis. Group 1 patients were significantly younger and more likely to be female than in group 2. Abdominal tenderness was less marked and there was a greater reliance on radiological investigations in patients receiving antibiotics. C-reactive protein and pre-operative temperature were significantly higher in group 1 patients compared to group 2. The perforation rate and complication rate were significantly greater in group 1. The commonest misdiagnoses were urinary tract infection and respiratory infection. Initial misdiagnosis results in significant delay before appendicectomy. This study shows that the clinical signs of acute appendicitis can be masked by prior treatment with antibiotics. The diagnosis of acute appendicitis must be considered and, if necessary, excluded in all children seen with abdominal pain who have recently been treated with antibiotics.

Ultrasonography in the diagnosis of acute appendicitis

Ultrasonography with graded compression was performed in 525 patients with clinical signs of acute appendicitis. Of 207 patients with surgically proven appendicitis the inflamed appendix (diameter greater than or equal to 6 mm) had been visualized sonographically in 177 (86 per cent). The score for non-perforated appendicitis (91 per cent) was higher than for perforated appendicitis (55 per cent). Twenty-four patients in whom an inflamed appendix was seen on ultrasonography did not undergo surgery because of rapidly subsiding symptoms ('abortive appendicitis'). Four of these 24 developed recurrent appendicitis warranting surgery. Two underwent elective appendectomy and 18 have remained symptom-free. Of 155 patients with a subsequently confirmed alternative condition, ultrasonography made the correct diagnosis in 140: bacterial ileocaecitis (69), mesenteric lymphadenitis (eight), gynaecological conditions (34), urological conditions (eight), caecal diverticulitis (six), perforated peptic ulcer (six), Crohn's disease (two) and miscellaneous conditions (seven). Of 139 patients in whom no definite diagnosis was made ultrasonography showed no abnormalities in 138. In four patients a false positive sonographic diagnosis of appendicitis was made and in two patients with appendicitis an alternative condition was incorrectly diagnosed. During the last 3 years of the study the negative appendicectomy rate was 7 per cent and delay beyond 6 h after admission occurred in only 2 per cent of patients with surgically proven appendicitis. When used to complement the clinical diagnosis ultrasonography improves the diagnostic accuracy and patient management in those suspected of having acute appendicitis.

Inflammatory Pseudotumour of the Caecum: A Case Report

Inflammatory pseudotumors of the caecum are uncommon. They pose problems with diagnosis. We report on a 35 year old female who presented with clinical signs of acute appendicitis. Intra-operatively, a caecal tumour was found with normal appendix and multiple enlarged mesenteric lymph nodes. A right hemicolectomy was performed. Histopathology findings revealed an inflammatory mass with abundant fibroblast proliferation with associated collagen formation, infiltrating bowel wall and pericaecal adipose tissue. She recovered well and was discharged home 5 days post-operatively. At present, she is free of symptoms.

Neuroimmune appendicitis

15-25% of appendices removed from patients with suspected appendicitis appear normal on histological examination. The cause of pain in such patients is unknown. Since the content of neuropeptides seems to be altered in chronic inflammation, we investigated possible changes in peptidergic innervation for substance P (SP), vasoactive intestinal peptide (VIP), and growth-associated protein-43 (GAP-43). Appendices classified as showing acute appendicitis, non-acute appendicitis (clinical signs of acute appendicitis, but histologically not inflamed), or normal were processed for SP, VIP, and GAP-43 immunocytochemistry. The density of SP immunostaining was assessed by digitised morphometry. 31 appendix specimens were studied (16 acute, 15 non-acute). 16 specimens were used as controls. Expression of GAP-43 was increased in the non-acute appendices. We observed larger amounts of SP-immunoreactive and VIP-immunoreactive nerves in the mucosal layer of the appendix in patients with non-acute appendicitis than in controls and patients with acute appendicitis (mean % area SP-immunoreactive 0.0496 [SD 0.0113] non-acute, 0.0221 [0.0049] acute, 0.0229 [0.0068] controls). In addition, a close spatial relation between SP-immunoreactive and VIP-immunoreactive nerve fibres and lymphoid cells was detected in the outer zone of lymph follicles. Neuroproliferation in the appendix, in association with an increase in neurotransmitters SP and VIP, may be involved in the pathophysiology of acute right abdominal pain in the absence of an acute inflammation of the appendix. Our data, together with increasing knowledge about the way in which the nervous system and immune cells interact, suggest that neuroimmune appendicitis is a distinct pathological entity.
