Abstract BACKGROUND:In appendicitis, elevated intra-luminal pressure and ischemic necrosis of mucosa causes tissue gangrene or perforation. This leads to cytotoxin facilitated progressive bacterial invasion or translocation into the hepatic parenchyma through portal system. This phenomenon interferes with the bilirubin excretion into the bile canaliculi.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.

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.

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/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.

Background: Appendicitis is the most common acute abdominal condition requiring emergency surgery, with a lifetime risk of 6%. Appendectomy continues to be one of the commonest procedures in general surgery, accounts for approximately 1% of all surgical operation. Despite the increased use of ultrasonography, computed tomography scanning and laparoscopy, the rate of misdiagnosis of appendicitis has remained constant (15.3%). The aim of this study was to whether Serum Bilirubin can be considered as a new laboratory marker to aid in the diagnosis of acute appendicitis and if so, does it have the predictive capacity to warn us about complicated appendicitis.Methods: This was prospective observational study done in Mahatma Gandhi Medical College and Research Institute, Pondicherry between November 2014 and August 2016. About 110 patients of acute appendicitis who had undergone appendicectomy were studied. Data was collected and analyzed critically.Results: Males 66 (60%) outnumbered females 44 (40%) and overall mean age was 26.61±12.37 years. Of the 110 patients, 9% were normal appendix, 59.09% were confirmed as acute appendicitis while 31.81% were diagnosed with complicated appendicitis on biopsy. The Sensitivity and Specificity of serum bilirubin as a marker in predicting Acute appendicitis and complicated appendicitis was 47.6% and 90.9% respectively. Similarly, the Positive predicative value and Negative predicative value for the same was 88.5% and 61.5% respectively with odds ratio 12.4 with significant p value <0.0001.Conclusions: Serum bilirubin is easily available test and cheap and can be estimated from the sample of blood drawn for routine blood investigations. Patients with clinical signs and symptoms of appendicitis and with hyperbilirubinemia should be identified as having a higher probability of complicated appendicitis. Hence, serum bilirubin levels have a predictive potential for the diagnosis of severity of acute appendicitis and need for early appendicectomy. If total serum bilirubin is added to already existing laboratory tests, then the diagnosis of complicated appendicitis in clinically suspected cases can be made with fair degree of accuracy, the need for CECT and MRI can be reduced and unnecessary delay in appendicectomy can be avoided.

Diagnosis of acute appendicitis can be challenging in some cases as the differentials can be exhaustive. Previous studies have demonstrated that hyperbilirubinemia is a more specific marker for appendicitis than white blood count (WBC) and C-reactive protein (CRP), but this investigation is still not commonly used in the diagnostic workup of appendicitis. This prospective study aims to evaluate serum bilirubin as a laboratory marker for simple and complicated appendicitis. We also investigated the diagnostic value of bilirubin in acute appendicitis and compared it with the WBC. In this prospective study, all patients who underwent appendicectomy at the Sulaimani Emergency Teaching Hospital between 1st November 2016 to 1st January 2017 were included. Preoperative total serum bilirubin was measured and compared with the final histopathology report. Patients were divided into 3 groups: non-inflamed appendix, simple appendicitis and complicated appendicitis. One hundred and 75 patients were analysed, 90 of them were females and 85 were males. Hyperbilirubinemia was found in 63% of patients with complicated appendicitis (p=0.001). Mean of bilirubin was significantly different between patients with complicated appendicitis and non-complicated appendicitis (1.101 vs 0.75 mg/dl; p= 0.0017). Bilirubin had a higher specificity (85%) than WBC (36%), but a lower sensitivity (63% vs 89%) for differentiating complicated appendicitis. Patients with suggestive features of acute appendicitis and raised serum bilirubin indicate a complicated case requiring early intervention to prevent peritonitis and septicaemia. Hyperbilirubinemia is a good indicator for complicated appendicitis and serum bilirubin measurement can be included in the work up of patients with suspected appendicitis.

Background: This study has compared the difference in serum bilirubin between patients with gangrenous and non-gangrenous appendicitis. Methods: A prospective analytical study of, 141 patients who underwent appendectomy, from March 2010 to March 2011 in Manipal Teaching Hospital, Pokhara, Nepal was carried out. Clinico-demographic data, Alvarado’s score, total serum bilirubin, total leucocyte count and histopathological report of all the cases were collected in a prestructured proforma. Comparison between gangrenous and non-gangrenous appendicitis groups was carried out using independent sample t test, Chisquare test, and direct logistic regression. The data was analyzed using SPSS 11.6 software. Result: Around 43% (61 out of 141) patients had gangrenous appendicitis and statistically significant difference was found between the two groups in total Alvarado’s score, total count and total bilirubin level. The effect size as indicated by eta square statistics was large for total bilirubin (eta squared=0.39) as compared to total Alvarado’s score (0.09) and total leucocyte count (0.05). Direct logistic regression model showed serum total bilirubin as the only independent variable to make a unique statistically significant contribution in predicting gangrenous appendicitis. Conclusion: Pre-operative assessment of serum total bilirubin can serve as an important maker of acute gangrenous appendicitis.
