“…The difference between the two studies is probably due to these morphological and pathological differences between children and adults. Incesu et al (31) reported the clinical usefulness of Gd-enhanced MRI in demonstrating acute appendicitis, and found that the normal appendix was not demonstrated on MRI even with Gd-contrast. This study showed that normal appendices were clearly demonstrated by MRI even without contrast.…”

Purpose: To describe the MR appearance of the normal appendix and the MR imaging characteristics of acute appendicitis with correlation to pathological severity. Materials and Methods:A total of 20 volunteers participated in this study to demonstrate normal appendices by MR imaging. A total of 37 consecutive patients with clinically diagnosed acute appendicitis were also scanned. T1-weighted (T1WI) spin-echo images, T2-weighted (T2WI) fast spin-echo, and fat-suppressed spectral presaturation inversion recovery T2-weighted (T2SPIR) fast spin-echo images were obtained. The MR criteria for considering acute appendicitis were as follows: 1) thickening of the appendiceal wall with high intensity on T2WI or T2SPIR; 2) dilated lumen filled with high intensity material on T2WI or T2SPIR; and 3) increased intensity of periappendiceal tissue on T2WI or T2SPIR. Results:The visibility of a normal appendix on MR imaging was 90% (18/20). It appeared as a cord-like structure of medium intensity without fluid collection in the lumen. A total of 30 cases with clinically diagnosed acute appendicitis had positive MR findings and all except one were pathologically proven. The one had cecal diverticulitis. These cases demonstrated filled lumen, with a hypointense wall on T1WI and slightly hyperintense on T2WI or T2SPIR. MR findings correlated well with pathological severity, especially a thicker wall, periappendiceal high intensity, and ascites were useful for suspecting severe appendicitis. Conclusion:Correct diagnosis of acute appendicitis was obtained with MRI, and correlated well with its pathological severity. MRI is a powerful alternative for diagnosing acute appendicitis especially for the patients in whom the radiation is major concern. ACUTE APPENDICITIS is one of the most common abdominal diseases and presents as an acute abdomen. The diagnosis is usually based on clinical and laboratory findings, however, approximately one-third of patients with acute appendicitis present with atypical clinical symptoms. This confusion leads to a high prevalence of unnecessary laparotomy, reported at 6% to 16% (1-5). The other cases demonstrate atypical and nonspecific symptoms shared with other abdominal diseases including cholecystitis, gastritis, enterocolitis, diverticulitis, mesenteric adenitis, gynecological disease (e.g., pelvic inflammatory disease [PID], tubo-ovarian abscess, ovarian cyst or torsion, endometriosis, degenerating uterine leiomyoma), and urological disorders (6 -12). In such clinically questionable cases, it is not uncommon that radiological evaluations provide useful information in making a differential diagnosis. An appropriate imaging procedure can prevent surgery delays and minimize the rate of negative laparotomies. Currently, the imaging modalities chosen to demonstrate an inflamed appendix, as well as its complications, are ultrasound (US) and computed tomography (CT). However, MR has not been applied to acute appendicitis.The first objective of this study was to describe the MR appearances of the normal appe...

“…Another major ad vantage of MR imaging is the avoidance of ionizing radiation (most cases of suspected acute appendicitis occur in children, with fe males more commonly affected than males [11,12]). To our knowledge, only one report for detection of acute appendicitis with MR imaging has been published; these authors recommendedfat-suppressed,gadolinium-en hanced MR imaging for accurate diagnosis [13]. The aim of our studywasto characterize the MR appearance of acute appendicitis, to determine the value of unenhanced MR imag ing, and to find the most accurate sequence for the depiction of acute appendicitis.…”

“…A recently published study [13] recom mends fat-suppressed, gadolinium-enhanced MR imaging for accurate diagnosis ofacute ap pendicitis. However, as our study shows, accu rate diagnosis of acute appendicitis may be made even without administration of contrast agent, which helps to reduce examination cost.…”

Coli have been associated with increased levels of total serum bilirubin levels. 16 Amongst the patients diagnosed with Acute appendicitis pre-operatively (n=70), 47 patients (47%) were found to have increased bilirubin (>1.2 mg/dL) while 53 patients (53%) has normal bilirubin levels (≤1.2 mg/dL).…”

Hyperbilirubinemia: a new diagnostic marker for perpendicular perforation

Background: Appendicitis is one of the commonest causes of abdominal pain requiring emergency surgery. Diagnosing acute appendicitis clinically still remains a common surgical problem as the clinical signs and symptoms of other abdominal pathologic conditions mimic the diagnosis of acute appendicitis. Delay in diagnosis and surgery for this condition may lead to various complications like perforation, abdominal abscess etc. By knowing perforation prior to the exploration, we can manage the condition very effectively in terms explaining the prognosis of disease, morbidity of surgery, wound infection, and requirement of emergent nature of surgery. Aim of the study is to determine of role of hyperbilirubinemia as a new diagnostic marker to predict gangrenous/perforated appendicitis.Methods: It’s a retrospective study was conducted in the department of surgery, MMCRI, Mysore during the period of January 2015 to December 2015 total of 100 patients with clinical as well as ultrasonographic diagnosis of acute appendicitis or appendiceal perforation were made. The serum bilirubin test was carried out in all the patients pre-operatively.Results: In the study, the total 100 patients enrolled for the study, hyperbilirubinemia (> 1.2 mg/dL) in present study was found in 47 patients with 19 acute and 28 patients perforated appendicitis of all the 100 patients while 53 patients had normal bilirubin levels (≤ 1.2 mg/dL) 51 patients acute and 2 patients perforated appendix.Conclusions: Total serum bilirubin appears to be a new promising laboratory marker for diagnosing appendicular perforation. The patients with clinical signs and symptoms of appendicitis and with hyperbilirubinemia without elevation of liver enzymes should be identified as having a higher probability of appendicular perforation, suggesting total serum bilirubin levels have a predictive potential for the diagnosis of appendicular perforation.
