Abstract BACKGROUND:Hyperbilirubinemia has also been found in infective diseases involving organs other than liver. The bacteremia/endotoxemia resulting in impaired hepatocyte function and bile secretion along with increased acute phase reactants contribute to the pathogenesis. In appendicitis, elevated intra-luminal pressure and ischemic necrosis of mucosa causes tissue gangrene or perforation. This is accompanied by bacterial cytotoxin facilitated progressive bacterial invasion. This elevated load of bacteria causes direct invasion or translocation into the portal system. Direct invasion of bacteria into the hepatic parenchyma interferes with the bilirubin excretion into the bile canaliculi biochemically rather than by any obstructive pathway.In the present study, establishment of a possible role of hyperbilirubinemia as a marker of gangrenous/perforated appendicitis has been studied.METHODS:After matching the inclusion and exclusion criteria, all cases of clinically diagnosed acute appendicitis were taken for this prospective, single center, observational study. Per-operative diagnosis was confirmed by histopathological examination.RESULTS:Out of 110 subjects of acute appendicitis 41 subjects (37.27%) had hyperbilirubinemia. Out of 35 subjects diagnosed as complicated appendicitis 32 subjects (91.42%) had raised total bilirubin levels, while the remaining 03(8.58%) had normal levels .Among 75 subjects diagnosed as acute simple appendicitis 09 subjects (12%) had raised total bilirubin level, while the remaining 66 subjects (88%) had normal levels .It was Mixed Type Of Hyperbilirubinemia in gangrenous/perforated appendicitis.The sensitivity of Total serum bilirubin in predicting complicated appendicitis was found 91.43% (76.942% to 98.196%), where as the specificity of this test was 88.00% (78.439% to 94.363%). positive predictive value and negative predictive value were 78.03% and 95.65% respectively.Positive likelihood ratio and negative likelihood ratio were found to be 7.619 and 0.097 respectively taking prevalence of Complicated appendicitis be 31.80%.ROC (Receiver Operating Characteristic) curve was obtained which shows optimal criterion at Total Bilirubin Level 1.06 mg/dl where sensitivity was 91.43% and specificity was 97.33% at 95% confidence interval with 31.8% disease prevalence.CONCLUSIONS:This is to conclude that Serum bilirubin level estimation, which is a simple, cheap and easily available laboratory test, can be added to the routine investigations in clinically suspected cases of acute appendicitis for early diagnosis of complications.Trial Registration: Registered with Clinical Trials Registry-India (ICMR-NIMS) with Registration number CTRI/2019/05/018879 Dated 01/05/2019.

Introduction: The aim of this study was to determine the role of hyperbilirubinemia as a new diagnostic tool for predictor of gangrenous / perforated appendicitis. Methods: Hospital based prospective study was conducted on 100 patients with perforated/gangrenous appendix Results: In acute appendicitis case out of 84 cases 26 cases bilirubin level was more than 1mg/dl, in gangrenous appendicitis out of 3 cases all cases bilirubin level was more than 1mg/dl and in perforated appendicitis out of 13 cases 12 cases bilirubin level was more than 1mg/dl Conclusion: It is concluded from present study that elevated total serum bilirubin without elevation of liver enzymes is a good indicator of appendicular perforation. Keywords: Perforation, Appendicitis, Bilirubin

Background: Elevation in serum bilirubin was reported recently, but the importance of the raised total bilirubin has not been stressed in acute appendicitis and appendicular perforation. The aim of the study was to establish the role of hyperbilirubinemia as a new diagnostic tool to predict gangrenous/perforated appendicitis. Subjects and Methods: This was a prospective observational study, which was conducted at the Gujarat Adani Institute of Medical Science, Bhuj, Kutch, Gujarat, India. A total of 100 patients clinically diagnosed as appendicitis from August 2018 to August 2019 at Gujarat Adani Institute of Medical Science, Bhuj, Kutch, Gujarat, India. Patients were clinically evaluated by detailed history, routine examination on initial contact with patients and the routine investigations as per surgery and anesthesia requirements with inclusion of serum total bilirubin. Based on histopathological examination patients will be categorized as positive (acute appendicitis with perforation and/or gangrene) and negative (acute appendicitis without perforation or gangrene). Results: Out of 100 patients, 20 were managed conservatively (mass formation) and was called for interval appendectomy after 6 weeks. In acute catarrhal appendicitis group 47 patients showed normal total bilirubin levels, whereas 8 patients showed increase in levels of total bilirubin.  In gangrenous appendicitis group all 10 patients showed elevated serum total bilirubin levels  In perforated appendicitis group consisted of 15, 11 patients showed elevated serum bilirubin levels and 4 patients showed normal total bilirubin levels. Conclusion: Serum bilirubin is easily available test and cheap and can be estimated from the sample of blood drawn for routine blood investigations.

Background: A diagnostic approach for complicated appendicitis is still controversial. We analyzed the preoperative laboratory markers that may predict complicated appendicitis.Methods: To study the role of leukocytosis, hyperbilirubinemia, decreased mean platelet volume (MPV) and increased international normalized ratio (INR) in the prediction of complicated appendicitis. Total 60 patients were enrolled and divided them into 2 groups, un-complicated (AUA) and complicated (ACA) acute appendicitis, each having 30 cases.Results: Total leucocyte count (TLC) >10000 mm³ was found in 70% of AUA cases and 80% of ACA cases serum bilirubin >1 mg/dl was found in 66.67% of AUA cases and 80 % of ACA cases. MPV<7.6 fL was found in 60% of AUA and 80% of ACA cases INR >1.2 was found in 20 % of AUA and 40% of ACA cases. TLC >10000/mm³, serum bilirubin >1 mg/dl and MPV <7.6 fL was found in 46.67% of AUA cases and 70 % of ACA cases.Conclusions: Total leucocyte count, serum bilirubin and mean platelet volume have a predictive potential for the diagnosis of complicated appendicitis.
