An evidence-based definition for perforated appendicitis derived from a prospective randomized trial
Shawn D. St. Peter Susan W. Sharp George W. Holcomb III Daniel J. Ostlie 《Journal of pediatric surgery》2008,43(12):2242-2245
Purpose
Appendicitis is the most common urgent condition in general surgery, and yet there is no evidence-based definition for perforation. Therefore, all retrospective data published on perforated appendicitis are unreliable because of an ill-defined denominator. For approximately 2 years beginning in April 2005, we performed a prospective randomized trial investigating 2 different antibiotic regimens for perforated appendicitis. During this study, we strictly defined perforation as a hole in the appendix or a fecalith in the abdomen. Before this prospective study, perforation was staff surgeon opinion. We investigated the abscess rates in both the perforated and nonperforated appendicitis populations before and during the study to determine if our definition was safe and that there was not an increased risk of abscess formation in patients treated as nonperforated.Methods
Records of all patients undergoing laparoscopic appendectomy for appendicitis during the immediate 2 years before using the definition were compared to those treated in the 2 years after the definition was implemented. Interval and incidental appendectomies were ruled out. The postoperative abscess rate (when perforation was not defined) was compared to the abscess rate of those for whom perforation was strictly defined.Results
There were 292 patients treated for acute nonperforated appendicitis in the 2 years before the definition and 388 patients after the definition. There were 131 patients treated for perforated appendicitis before the definition and 161 after the definition was implemented. The abscess rate in those with perforated appendicitis increased from 14% to 18% after the definition was used. However, after the definition began to be used, the abscess rate for those patients treated as nonperforated decreased from 1.7% to 0.8%.Conclusions
Defining perforation as a hole in the appendix or a fecalith in the abdomen is effective in identifying the patients at risk for postoperative abscess formation. Application of these criteria would allow substantial reduction in therapy for patients with purulent or gangrenous appendicitis who do not possess the same abscess risk. These data outline the first evidence-based definition of perforation. 相似文献2.
Purpose
A fecalith is a fecal concretion that can obstruct the appendix leading to acute appendicitis. We hypothesized that the presence of a fecalith would lead to an earlier appendiceal perforation.Methods
Between January 2001 and December 2005, the charts of all patients younger than 18 years old who underwent appendectomy at our institution were reviewed. Duration of symptoms and timing between presentation and operation were noted along with radiologic, operative, and pathologic findings.Results
There were 388 patients who met the study criteria. A fecalith was present in 31% of patients (n = 121). The appendix was perforated in 57% of patients who had a fecalith vs 36% in patients without a fecalith (P < .001). The overall rate of interval appendectomies was 12%. A fecalith was present on the initial radiologic studies of 36% of the patients who had interval appendectomies, and the appendix was perforated significantly sooner in these patients when compared to those without a fecalith (91 vs 150 hours; P = .036).Conclusion
The presence of fecalith is associated with earlier and higher rates of appendiceal perforation in pediatric patients with acute appendicitis. An expedient appendectomy should therefore be performed in the pediatric patient with a radiologic evidence of fecalith. 相似文献3.

INTRODUCTION
No reliably specific marker for acute appendicitis has been identified. Although recent studies have shown hyperbilirubinaemia to be a useful predictor of appendiceal perforation, they did not focus on the value of bilirubin as a marker for acute appendicitis. The aim of this study was to determine the value of hyperbilirubinaemia as a marker for acute appendicitis.MATERIALS AND METHODS
A retrospective analysis of appendicectomies performed in two hospitals (n=472). Data collected included laboratory and histological results. Patients were grouped according to histology findings and comparisons were made between the groups.RESULTS
The mean bilirubin levels were higher for patients with simple appendicitis compared to those with a non-inflamed appendix (p<0.001). More patients with simple appendicitis had hyperbilirubinaemia on admission (30% vs 12%) and the odds of these patients having appendicitis were over three times higher (odds ratio: 3.25, p<0.001). Hyperbilirubinaemia had a specificity of 88% and a positive predictive value of 91% for acute appendicitis. Patients with appendicitis who had a perforated or gangrenous appendix had higher mean bilirubin levels (p=0.01) and were more likely to have hyperbilirubinaemia (p<0.001). The specificity of hyperbilirubinaemia for perforation or gangrene was 70%. The specificities of white cell count and C-reactive protein were less than hyperbilirubinaemia for simple appendicitis (60% and 72%) and perforated or gangrenous appendicitis (19% and 36%).CONCLUSIONS
Hyperbilirubinaemia is a valuable marker for acute appendicitis. Patients with hyperbilirubinaemia are also more likely to have appendiceal perforation or gangrene. Bilirubin should be included in the assessment of patients with suspected appendicitis. 相似文献4.

Background and Objectives:
The advantages of laparoscopic appendectomy over open appendectomy have not yet been clearly demonstrated. The present study evaluated our early experience with laparoscopic appendectomy in children, in terms of its safety, effectiveness, technical difficulties, and economics.Methods:
We reviewed the records of 50 cases involving laparoscopic appendectomy performed at our affiliated institutions between September, 1994, and September, 1996. Patient age ranged from 6 to 18 years (mean, 14 years). Thirty-two patients had acute nonperforated appendicitis, six had perforated appendicitis, two had fibrosis of the appendix, and ten had a histologically normal appendix.Results:
In five patients the laparoscopic procedures were converted to open appendectomies because of technical difficulties. There were postoperative complications in four patients: one incomplete appendectomy which subsequently required an open appendectomy for completion, one pelvic abscess, one bowel obstruction, and one minor wound infection.Conclusions:
Laparoscopic appendectomy is a safe and effective procedure. It takes longer operative time than open appendectomy. Length of hospitalization and incidence of postoperative complications are equivalent to those of open appendectomy. Economic benefits are difficult to assess at present. In sum, we believe that with better training, surgical techniques and equipment, laparoscopic appendectomy will eventually become the surgical procedure of choice in appendicitis. 相似文献5.

Objective
To evaluate the influence of age on the evolution and severity of peritonitis.Design
A chart review.Setting
An adult university hospital.Patients
One hundred and twenty-two patients with acute appendicitis and 100 patients with acute colonic diverticulitis requiring operation or percutaneous drainage.Main Outcome Measures
Patient age and sex, presence of perforation or gangrene (appendicitis), extent of peritonitis (diverticulitis); duration of symptoms prior to admission; admission leukocyte count; duration of hospitalization before surgery; length of hospital stay; and death rate.Results
Patients with acute appendicitis who were aged 65 years or older were three times more likely than younger patients to have a gangrenous or perforated appendix (odds ratio 3.1, 95% confidence interval 1.1 to 8.4, p < 0.05); older patients with perforated diverticulitis were three times more likely than younger patients to have generalized peritonitis than localized (pericolic or pelvic) peritonitis (odds ratio 2.9, 95% confidence interval 1.2 to 7.5, p < 0.05).Conclusion
These findings are consistent with the hypothesis that the biologic features of peritonitis differ in the elderly, who are more likely to present with an advanced or severe process than young patients. 相似文献6.

Background and Objectives:
To compare laparoscopic appendectomy with traditional open appendectomy.Methods:
Seventy-one patients requiring operative intervention for suspected acute appendicitis were prospectively compared. Thirty-seven patients underwent laparoscopic appendectomy, and 34 had open appendectomy through a right lower quadrant incision. Length of surgery, postoperative morbidity and length of postoperative stay (LOS) were recorded. Both groups were similar with regard to age, gender, height, weight, fever, leukocytosis, and incidence of normal vs. gangrenous or perforated appendix.Results:
Mean LOS was significantly shorter for patients with acute suppurative appendicitis who underwent laparoscopic appendectomy (2.5 days vs. 4.0 days, p<0.01). Mean LOS was no different when patients classified as having gangrenous or perforated appendicitis were included in the analysis (3.7 days vs. 4.1 days, P=0.11). The laparoscopy group had significantly longer surgery times (72 min vs. 58 min, p<0.001). There was no significant difference in the incidence of postoperative morbidity.Conclusions:
Laparoscopic appendectomy reduces LOS as compared with the traditional open technique in patients with acute suppurative appendicitis. The longer operative time for the laparoscopic approach in our study is likely related to the learning curve associated with the procedure and did not increase morbidity. 相似文献7.

Background
Appendicitis presents on a spectrum ranging from inflammation to gangrene to perforation. Studies suggest that gangrenous appendicitis has lower postoperative infection rates relative to perforated cases. We hypothesized that gangrenous appendicitis could be successfully treated as simple appendicitis, reducing length of stay (LOS) and antibiotic usage without increasing postoperative infections.Methods
In February 2016, we strictly defined complex appendicitis as a hole in the appendix, extraluminal fecalith, diffuse pus or a well-formed abscess. We switched gangrenous appendicitis to a simple pathway and reviewed all patients undergoing laparoscopic appendectomy for 12?months before (Group 1) and 12?months after (Group 2) the protocol change. Data collected included demographics, appendicitis classification, LOS, presence of a postoperative infection, and 30-day readmissions.Results
Patients in Group 1 and Group 2 were similar, but more cases of simple appendicitis occurred in Group 2. Average LOS for gangrenous appendicitis patients decreased from 2.5 to 1.4?days (p?<?0.001) and antibiotic doses decreased from 5.2 to 1.3 (p?<?0.001). Only one gangrenous appendicitis patient required readmission, and one patient in each group developed a superficial infection; there were no postoperative abscesses.Conclusions
Gangrenous appendicitis can be safely treated as simple appendicitis without increasing postoperative infections or readmissions.Type of study

Background
The aim of this study was to investigate the morbidity associated with appendectomy in living liver donors undergoing hepatectomy.Methods
The medical records of 338 donors who underwent hepatectomies for living-donor liver transplantation between 2008 and 2010 were reviewed retrospectively. The patients were divided into 2 groups on the basis of appendectomy: patients in group A (n = 126) received incidental appendectomies in conjunction with donor hepatectomy, and those in group B (n = 212) underwent hepatectomy alone.Results
No significant difference in age, gender, or body mass index was found between groups. The wound infection rate (P = .037) and length of hospital stay (P = .0038) were higher in group A than in group B. Intraoperative findings in 126 donors in group A were subserosal (n = 4), retrocecal (n = 6), or hard nodular (n = 11) appendix; hyperemic appendix with edema (n = 9); appendix length ≥8 cm (n = 18); and palpable fecalith (n = 78). Histopathologic examination of appendix specimens revealed lymphoid hyperplasia with a fecalith (n = 32), fecalith only (n = 32), acute appendicitis (n = 20), normal anatomy (n = 18), fibrous obliteration (n = 9), lymphoid hyperplasia (n = 9), Enterobius vermicularis (n = 3), appendiceal neuroma (n = 1), carcinoid tumor (n = 1), and mucoceles (n = 1).Conclusion
Although incidental appendectomy increased the wound infection rate and length of hospital stay, this procedure is necessary for the prevention of potential complications due to appendicitis when the exploration of the ileocecal region in patients undergoing donor hepatectomy reveals one or more of the following: appendix length ≥8 cm; dropsical, hyperemic, subserosal, nodular, and/or retrocecal appendix; and/or palpable fecaloma. 相似文献9.
Background
Acute appendicitis is among the most common indications for surgery in children in the Western world. The epidemiology of acute appendicitis in the United States has not been recently analyzed in a population-based cohort study.Methods
Here, we describe the epidemiology of acute appendicitis in the pediatric population in New England from 2000 to 2006.Results
Our results show that there is clustering of perforated and nonperforated appendicitis by hospital catchment area (Moran I index 0.01 and 0.03, respectively). The overall incidence of nonperforated appendicitis decreased over our study period by 9.7% (P < .05), the proportion of perforated appendicitis did not change significantly over our study period, and there was a 38% decrease in the proportion of negative appendectomies (P < .05).Conclusions
There were trends toward increased operative volume for pediatric surgeons as well as sharp increases in the use of laparoscopy and early discharge with home health services. Our results demonstrate that the epidemiology, outcomes, and trends in treatment of acute appendicitis continue to change. 相似文献10.

Introduction
Inflammatory markers such as white cell count (WCC) and C-reactive protein (CRP) and, more recently, bilirubin have been used as adjuncts in the diagnosis of appendicitis. The aim of this study was to determine the diagnostic accuracy of the above markers in acute and perforated appendicitis as well as their value in excluding the condition.Methods
A retrospective analysis of 1,169 appendicectomies was performed. Patients were grouped according to histological examination of appendicectomy specimens (normal appendix = NA, acute appendicitis = AA, perforated appendicitis = PA) and preoperative laboratory test results were correlated. Receiver operating characteristic (ROC) curve area analysis (area under the curve [AUC]) was performed to examine diagnostic accuracy.Results
ROC analysis of all laboratory variables showed that no independent variable was diagnostic for AA. Good diagnostic accuracy was seen for AA when all variables were combined (WCC/CRP/bilirubin combined AUC: 0.8173). In PA, the median CRP level was significantly higher than that of AA (158mg/l vs 30mg, p<0.0001). CRP also showed the highest sensitivity (100%) and negative predictive value (100%) for PA. CRP had the highest diagnostic accuracy in PA (AUC: 0.9322) and this was increased when it was combined with WCC (AUC: 0.9388). Bilirubin added no diagnostic value in PA. Normal levels of WCC, CRP and bilirubin could not rule out appendicitis.Conclusions
CRP provides the highest diagnostic accuracy for PA. Bilirubin did not provide any discriminatory value for AA and its complications. Normal inflammatory markers cannot exclude appendicitis, which remains a clinical diagnosis. 相似文献11.
Introduction
The prevailing view on appendicitis is that the main aetiology is obstruction owing to faecoliths in adults and lymphoid hyperplasia in children. Faecoliths on imaging studies are believed to correlate well with appendicitis.Methods
A retrospective chart review was conducted of 1,014 emergency appendicectomy patients between 2001 and 2011. Faecolith prevalence in adult and paediatric appendicectomy specimens with and without perforation was studied. The sensitivity and positive predictive value (PPV) of computed tomography (CT) for identifying faecoliths in the pathology specimen were examined.Results
Overall, faecoliths were found in 18.1% (178/986) of appendicitis specimens and 28.6% (8/28) of negative appendicectomies. Faecolith prevalence for positive cases was 29.9% (79/264) in paediatric patients and 13.7% (99/722) in adults (p<0.05). Faecolith prevalence was 39.4% in perforated appendicitis but only 14.6% in non-perforated appendicitis (p<0.05). In adults, faecolith prevalence was 27.5% in perforated appendicitis and 12.0% in non-perforated appendicitis (p<0.05) while in paediatric patients, it was 56.1% in perforated appendicitis and 22.7% in non-perforated appendicitis (p=0.00). Sensitivity and PPV of preoperative CT in identifying faecoliths on pathology were 53.1% (86/162) and 44.8% (86/192) respectively.Conclusions
Faecolith prevalence is too low to consider the faecolith the most common cause of non-perforated appendicitis. Faecoliths are more prevalent in paediatric appendicitis than in adult appendicitis. Preoperative CT is an unreliable predictor of faecoliths in pathology specimens. 相似文献12.

INTRODUCTION
Intestinal malrotation is a rare congenital anomaly, and acute appendicitis associated with intestinal malrotation is extremely rare.PRESENTATION OF CASE We report a rare case of a 47-year-old Japanese woman diagnosed with barium-related perforated appendicitis associated with intestinal malrotation. We used a transumbilical single-incision laparoscopic approach to resect the appendix, and the procedure was completed successfully without perioperative complications.DISCUSSION
To our knowledge, single-incision laparoscopic surgery for appendicitis associated with intestinal malrotation has not been reported yet. In cases with mobile cecum such as this one, mobilization from inflammatory adhesion of the surrounding structures is easy.CONCLUSION
We conclude that transumbilical single-incision laparoscopic appendectomy is a simple and less invasive method for treating appendicitis associated with intestinal malrotation. 相似文献13.

INTRODUCTION
Atypical presentations of appendix have been reported including backache, left lower quadrant pain and groin pain from a strangulated femoral hernia containing the appendix. We report a case presenting an epigastric pain that was diagnosed after computed tomography as a perforated appendicitis on intestinal malrotation.PRESENTATION OF CASE
A 27-year-old man was admitted with a three-day history of epigastric pain. Physical examination revealed tenderness and defense on palpation of epigastric region. There was a left subcostal incision with the history of diaphragmatic hernia repair when the patient was 3 days old. He had an intestinal malrotation with the cecum fixed at the epigastric region and the inflamed appendix extending beside the left lobe of liver.DISCUSSION
While appendicitis is the most common abdominal disease requiring surgical intervention seen in the emergency room setting, intestinal malrotation is relatively uncommon. When patients with asymptomatic undiagnosed gastrointestinal malrotation clinically present with abdominal pain, accurate diagnosis and definitive therapy may be delayed, possibly increasing the risk of morbidity and mortality.CONCLUSION
Atypical presentations of acute appendicitis should be kept in mind in patients with abdominal pain in emergency room especially in patients with previous childhood operation for diaphragmatic hernia. 相似文献14.

BACKGROUND: Appendicitis is encountered predominantly in Western, industrialized countries. Animal experiments and clinical studies have suggested an obstructive fecalith as a cause of acute appendicitis. It was hypothesized that patients with acute appendicitis would have a longer colonic transit time and more fecal retention reservoirs (coprostasis) than healthy control persons, thus favoring the occurrence of a fecalith in the appendix. METHODS: Sixty-eight patients scheduled for appendectomy were included in this approved study. Before surgery, a plain abdominal radiograph was taken; at surgery, the degree of inflammation of the appendix was recorded, along with the presence or absence of a fecalith. Six weeks postoperatively, the patients underwent a colonic transit study. A cohort of 44 control persons over 18 years of age was selected at random to undergo the same marker study as the patients. The parameters studied were the number of radiopaque markers (h), the fecal retention or load (score 0-3) in the right, left, and distal colonic segments, and the number of fecaliths. RESULTS: Twelve patients were excluded; i.e., 56 patients and 44 controls were eligible for most analyses. In the patient group, statistically significant correlations were found between fecal loading scores and the number of markers (transit time) both overall and within the left and distal colonic segments (all p < 0.05). In the control subjects, there was significance with regard to the distal segment. The median colon transit time was 25.0 h (range 1-107 h) in patients with appendicitis compared with 19.0 h (range 0-71 h) in controls (p = NS). The transit time was longer in the right, left, and distal colon in patients than in control subjects, although not to a statistically significant extent. The total and segmental fecal loads in the colon did not differ significantly between patients and controls. A fecalith occurred in 49.0% of the patients and was in most cases associated with a gangrenous or perforated appendix. If a fecalith was not found, this correlated to a significant extent with a high fecal loading score in the left colon (p = 0.04). CONCLUSIONS: An obstructive fecalith occurred in one-half of the patients with acute appendicitis. The appendicitis patients had a colonic transit time similar to that in healthy controls. Furthermore, there was no difference in colonic fecal loading between patients and controls. In consequence, the occurrence of a fecalith could not be attributed to delayed colonic transit or fecal loading. However, we discovered greater amounts of feces in the colon of both patients and controls than would have been expected physiologically, and the role of these fecal reservoirs has yet to be understood. 相似文献

Background
Closure of the appendiceal stump is the most critical part of laparoscopic appendectomy. Establishing the average diameter of the inflamed appendix, and forming the appropriate size of clip, endoloop or stapler length, would make this critical phase of laparoscopic appendectomy easier.Methods
One hundred and fifty consecutive patients, with the diagnosis of acute appendicitis, were included in this study and divided into three groups according to the histological verification of the status of the infection, as follows: phlegmonous, gangrenous and perforated forms of acute appendicitis. The external diameter of the appendiceal base was measured, and the widest part of the appendix with the mesoappendix and the tip, with the help of Vernier callipers, and the measurement was expressed in millimetres.Results
The average size of the appendiceal base in the phlegmonous form was 10.29 ± 3.13, in the gangrenous form 12.41 ± 3.56, and in the perforated form 12.42 ± 3.64. The maximal size of base was observed in the perforated form, 23.13 mm. The dimensions of the appendiceal base, the central part and the tip in the phlegmonous form were statistically significantly smaller than in the gangrenous and perforated forms of acute appendicitis. The size of the appendix did not differ statistically significantly in the gangrenous and perforated forms of acute appendicitis.Conclusion
In view of the price, the size of the opening, radiological advantage and biocompatibility, the Hem-o-lok clip is the most effective, although its internal diameter should be increased. The DS clip is also effective, but the size of the opening sometimes makes application difficult, and possibly increasing the length of the legs and the opening would make this clip ideal. Staplers have the best characteristics, but their price means they are an option only for forms where it is not possible to close the stump using other methods.16.
Background
There is little information available to inform choice of technique for appendiceal stump control in pediatric laparoscopic appendectomy (LA). We compared complications (stump leak, intra-abdominal abscess formation [IAA], surgical site infection [SSI]) in children undergoing LA for perforated (PA) and nonperforated appendicitis (NPA) by technique of appendiceal stump control.Methods
All children who underwent LA for confirmed acute appendicitis between 2006 and 2009 were reviewed. Choice of stump control (endoloop [EL] or endostapler [ES]) was determined by surgeon preference. Interactions between stump closure techniques and other potential confounders (intra-abdominal drain, irrigation, different antibiotic regimens) were explored using a logistic regression model.Results
Of 242 patients undergoing LA, 57 (23.6%) had PA. In the PA group the appendiceal stump was closed with EL in 47 (82.5%) patients, while in the NPA group EL was used in 161 (87%) patients. Among PA patients, IAA was more common in the ES than the EL group (5 of 10 [50%] v. 6 of 47 [12.7%]). There was no significant difference in rates of SSI. Among NPA patients, there were no differences in rates of IAA or SSI. There were no stump leaks in either group. Logistic regression analysis confirmed the predictive effect of ES use on IAA formation in PA (adjusted odds ratio 7.09; 95% confidence interval 1.08–46.13; p = 0.042).Conclusion
Our data suggest that in most cases of PA, the appendiceal stump can be safely controlled with EL. Within the PA group, the higher rates of IAA seen in ES patients may be attributable to the quality of the appendiceal stump rather than the technique of closure. 相似文献17.

Background
Although luminal obstruction has traditionally been viewed as the underlying cause of appendicitis, recent evidence has suggested that the disease may result directly from invasion by specific pathogens, e.g. Fusobacterium nucleatum. The purpose of this study was to survey microbial communities within pediatric appendectomy specimens using a culture-independent approach.Methods
We performed 16S ribosomal gene sequence analysis to profile the microbiota present within luminal fluid obtained from 22 pediatric appendectomy specimens. These included 10 simple appendicitis cases, 5 perforated appendicitis cases, 2 interval appendectomies, and 5 incidental appendectomies.Results
Samples could be divided into 2 distinct clusters based upon the composition of the appendiceal bacterial communities. Appendicitis samples contained an increased abundance of Fusobacterium spp. and a reduced abundance of Bacteroides spp. relative to non-appendicitis cases. Appendicitis samples also contained variable amounts of other oral taxa such as Porphyromonas, Parvimonas, and Gemella, whereas these taxa were generally absent from non-appendicitis samples.Conclusions
Acute appendicitis is associated with an abundance of Fusobacterium spp. and other pathogens commonly found in the oral cavity. Further research is needed to determine whether these organisms directly cause appendicitis or rather proliferate in the appendix as a secondary consequence of inflammation. 相似文献18.

Introduction
Adhesive small bowel obstruction (SBO) is a common postoperative complication. Published data in the pediatric literature characterizing SBO are scant. Furthermore, the relationship between the risk of SBO for a given procedure is not well described. To evaluate these parameters, we reviewed the incidence of SBO after laparoscopic appendectomy (LA) and open appendectomy (OA) performed at our institution.Methods
With institutional review board approval, all patients that developed SBO after appendectomy for appendicitis from January 1998 to June 2005 were investigated. Hospital records were reviewed to identify the details of their postappendectomy SBO. The incidences of SBO after LA and OA were compared with χ2 analysis using Yates correction.Results
During the study period, 1105 appendectomies were performed: 477 OAs (8 converted to OA during laparoscopy) and 628 LAs. After OA, 7 (6 perforated appendicitis) patients later developed SBO of which 6 required adhesiolysis. In contrast, a patient with perforated appendicitis developed SBO after LA requiring adhesiolysis (P = .01). The mean time from appendectomy to the development of intestinal obstruction for the entire group was 46 ± 32 days.Conclusions
The overall risk of SBO after appendectomy in children is low (0.7%) and is significantly related to perforated appendicitis. Small bowel obstruction after LA appears statistically less common than OA. Laparoscopic appendectomy remains our preferred approach for both perforated and nonperforated appendectomy. 相似文献19.

Purpose
Our aim was to establish the role of hyperbilirubinemia as a predictive parameter for the prediction of either acute, or gangrenous/perforated appendicitis as well as to compare other parameters in a similar role.Methods
Medical files of the patients who underwent appendectomies between September 2013 and September 2014 were evaluated. Age, gender, preoperative white blood cell count (WBC), neutrophil count (NEU), neutrophil percentage (NEU%), C-reactive protein (CRP), total/direct/indirect bilirubin levels, and the postoperative histopathological findings were recorded. The Fisher’s exact, Pearson’s χ 2, ANOVA, and Kruskal–Wallis tests while logistic regression for multivariate analysis was performed. p < 0.05 was accepted as statistically significant.Results
The study group of 162 patients consisted of 97 (60 %) men and 65 (40 %) women with a median age of 36 (18–90). Histopathological examinations revealed normal appendix in 21 (13 %) patients, non-complicated acute appendicitis in 100 (62 %), and appendiceal gangrene/perforation in 41 (25 %) patients. WBC, NEU, NEU%, and CRP levels were significantly higher in cases of acute and gangrenous/perforated appendicitis (p < 0.01). Total and direct bilirubin levels were also significantly elevated in patients with acute and gangrenous/perforated appendicitis (p < 0.01). According to multivariate analysis, elevated CRP levels were associated with 14 times, elevated total bilirubin levels were associated with five times, and elevated direct bilirubin levels were associated with 36 times greater risk for appendiceal gangrene/perforation (p < 0.01, p < 0.05, p < 0.01, respectively).Conclusions
Hyperbilirubinemia, especially with elevated direct bilirubin levels, may be considered as an important marker for the prediction of appendiceal gangrene/perforation.20.
