Bardakçi O, Bahçecioğlu İB, Tatli F, Özgönül A, Güldür ME, Uzunköy A. Does one of the two most commonly used scoring systems have a decisive advantage over the other in diagnosing acute appendicitis in pregnant women? Medicine (Baltimore) 2023; 102:e33596. [PMID: 37115072 PMCID: PMC10145901 DOI: 10.1097/md.0000000000033596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Revised: 03/29/2023] [Accepted: 03/31/2023] [Indexed: 04/29/2023] Open
Abstract
This study aimed to compare the accuracy and reliability of Alvarado Score (AS) and Appendicitis Inflammatory Response Score (AIRS) in pregnant women undergoing surgery for acute appendicitis (AA). The files of 53 pregnant women with a diagnosis of AA who underwent surgery in our clinic between February 2014 and December 2018 were examined retrospectively. The patients were divided into 3 groups as follows: first trimester between 0 and 14 weeks, second trimester between 15 and 28 weeks, and third trimester between 29 and 42 weeks. The AS and AIRS values were calculated according to preoperative physical examination and laboratory results. The mean age of the patients was 28.58 (18-44) years. According to the pathology results, appendicitis was detected in 16 of 23 patients in the first trimester, in 22 of 25 patients in the second trimester, and in 2 of 5 patients in the third trimester. The AIRS was ≥ 9 in 9 patients and the AS was ≥ 7 in 19 of the 23 patients in the 1st trimester, while the AIRS was ≥ 9 in 11 patients and the AS was ≥ 7 in 19 of the 25 patients in the 2nd trimester. However, in the 3rd trimester, the AIRS was ≥ 9 in 2 patients and AS was ≥ 7 in 4 of the 5 patients. In conclusion, when the data obtained from the present study were evaluated, it was determined that both AS and AIRS are effective methods for diagnosing AA in pregnant women.

ANZ J Surg 2021; 92:121-127. [PMID: 34967103 DOI: 10.1111/ans.17443] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 12/15/2021] [Accepted: 12/17/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Acute appendicitis (AA) is the most frequently seen surgical emergency in pregnant women and the most frequently encountered cause of non-obstetric acute abdomen. Due to the physiological and anatomical changes that occur during pregnancy and the limited use of radiological methods, it is difficult to diagnose AA during pregnancy. These conditions increase the risk of morbidity and mortality; therefore, it is crucial to identify ideal laboratory markers that can be utilized to diagnose disease. METHODS One hundred and ten pregnancies that fulfilled the inclusion criteria for AA diagnosis were retrospectively analysed between 2010 and 2021. Markers with high diagnostic values were discussed. RESULTS The patients were divided into three groups as follows; Group I: negative appendectomy (n = 19); Group IIa: uncomplicated appendicitis (n = 59); Group IIb: complicated appendicitis (n = 32). There was no statistically significant difference in mean age or gestational week (P > 0.05). Group IIb had a higher rate of complications and a longer length of hospital stay (P < 0.05). There were significant differences between the groups in terms of white blood cell (WBC), neutrophil, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein, lymphocyte-to- C-reactive protein ratio, total, direct, and indirect bilirubin values (P < 0.05). While platelet and lactate dehydrogenase (LDH) values did not differ substantially between groups, both were found to have a high diagnostic value. CONCLUSION It was concluded that WBC, neutrophil, NLR, PLR, total, direct and indirect bilirubin levels could be utilized to diagnose AA. Moreover, levels of WBC, neutrophil, NLR, platelet, PLR, LDH, total, direct and indirect bilirubin can be utilized to diagnose complicated appendicitis.

Abstract
Background: Acute appendicitis is the most frequently encountered non-obstetric disease requiring surgical intervention during pregnancy. Early diagnosis reduces maternal and fetal morbidity / mortality rates.
Aim: This study aims to investigate hemogram parameters in the diagnosis of acute appendicitis in pregnant women.
Material and Methods: A retrospective case-controlled study was conducted in three groups. Thirty-nine pregnant patients with acute appendicitis (Group A), 39 fertile nonpregnant patients with acute appendicitis (Group B), and 39 healthy pregnant women (Group C) were included in the study. WBC, neutrophil count, lymphocyte count, NLR, PLR, MPV and RDW values were compared.
Results: The mean NLR values in group A, group B and group C were 7.39 (1.58–46.6), 5.66 (1–20) and 4.23 (1.54–10.77) respectively, and there was a significant difference in NLR values between the groups (P= 0.002). The mean PLR values in group A, group B and group C were 159.09 (69.1–574), 134.28 (21.5-360) and 120 (68.7–334) and difference was statistically significant (P= 0.019). Cutoff points for WBC count was 14155 106/μL (51,3% sensitivity, 82,1% specificity), for neutrophil count is 10955 106/μL (53,8% sensitivity, 84,6% specificity), for NLR is 9.23 (46,2% sensitivity, 92,3% specificity) and PLR is 157,6 (51,3% sensitivity and 82,1% specificity) NLR had largest area under the curve with 0.667 NLR.
Conclusion: Neutrophil count, WBC and PLR were found to be the most valuable inflammatory parameters however, RDW, Lymphocyte count, and MPV levels are not found valuable markers in terms of sensitivity and specificity in the diagnosis of acute appendicitis in pregnant patients by this study.

Abstract
INTRODUCTION Acute appendicitis is the commonest surgical emergency during pregnancy. The aim of this study is to evaluate the outcomes between antibiotic therapy and appendectomy in the management of uncomplicated appendicitis during gestation. METHODS From January 2015 to April 2019, there were 2174 emergency appendicitis diagnosed in the University of Hong Kong-Shenzhen Hospital. Among them, 54 pregnant women were diagnosed with acute uncomplicated appendicitis and the clinical records were reviewed. Clinical demographics and outcomes including gestational age at delivery, mode of delivery, birth weight, APGAR score at 1 minute, fetal loss and overall length of stay were compared between the operation group and the antibiotic treatment group. RESULTS The baseline characteristics showed no statistically significant difference between the two groups (P > .05). In the appendectomy group (n = 20), one patient had wound infection while none of the patients in the antibiotic therapy group (n = 34) experienced any complication. In the antibiotic treatment group, appendicitis recurred in one patient during pregnancy and in two patients after deliveries, which were all treated with appendectomy. The mean hospital stay of the antibiotic treatment group was shorter than that of the appendectomy group, but there was no significant difference (4.94 ± 2.6 days vs 6.25 ± 3.5 days, P = .540). There was no difference in gestational age at delivery, mode of delivery, birth weight and APGAR scores between the two groups (P > .05). CONCLUSIONS For acute uncomplicated appendicitis during pregnancy, antibiotics treatment is a safe and feasible option.

Abstract
Background Although laparoscopic appendectomy increases its popularity today, the answer to the question of whether to perform open or laparoscopic appendectomy during pregnancy is appropriate in many studies, and the choice of surgery depends on the surgeon. Herein, we aimed to evaluate the variables that affect undesirable pregnancy outcomes that occur as a result of appendicitis during pregnancy. Methods Seventy-eight pregnant patients with acute appendicitis who underwent laparoscopic or open technique intervention enrolled in this retrospective study. In addition to the demographic structure of the patients, surgical technique, the number of pregnancies, multiple pregnancy status, surgical pathologies, laboratory values, radiological imaging methods, and length of hospital stay were evaluated. The severity of appendicitis was classified according to the pathology results. The patients were divided into two groups according to the outcomes of their pregnancy. Preterm delivery and abortion involved in the study as a single complication section. Results The mean age of the pregnant patients was 28.6 ± 5. Of the 78 pregnant women with appendicitis, 47.4% had their first pregnancy, 37.2% had their second pregnancy, and 15.4% had 3 or more pregnancies. The preterm delivery and abortus were 19.5% in the open appendectomy (OA) group and 16.2% in the laparoscopic appendectomy (LA) group. No statistically significant difference was detected in this group in terms of appendicitis pathology triggering preterm delivery or abortion (p 0.075). When white blood count (WBC) and C-reactive protein (CRP) were evaluated by laboratory findings, CRP was found to be statistically significantly higher in patients with preterm birth (p 0.042). Conclusion Consequently, acute appendicitis may cause serious intra-abdominal infection and inflammation in addition to the complexity of the diagnosis due to the nature of pregnancy, as well as undesired pregnancy outcomes with the surgical technique, or independently with other variables.

A comparison of nine different systems. World J Emerg Surg 2020; 15:34. [PMID: 32423408 PMCID: PMC7236497 DOI: 10.1186/s13017-020-00310-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Accepted: 04/21/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Acute appendicitis is the most common non-gynecological emergency during pregnancy. The diagnosis of appendicitis during pregnancy is challenging due to changes in both physiological and laboratory variables. Guidelines suggest patients with suspected acute appendicitis should be stratified based on clinical scoring systems, to optimize the use of diagnostic imaging and prevent unnecessary surgery. Surgeons require additional information beyond that provided by imaging studies before deciding upon exploratory laparoscopy in patients with a high suspicion of appendicitis. Various scoring methods have been evaluated for the diagnosis of acute appendicitis. However, there is no consensus on a method to use during pregnancy, and a detailed comparison of existing scoring methods for this purpose has not yet been conducted. The purpose of this study was to evaluate the efficacy of the most popular scoring systems applied to diagnose acute appendicitis during pregnancy. METHODS This single-center retrospective study included 79 pregnant patients who were admitted to the emergency department with abdominal pain between May 2014 and May 2019. The patients were diagnosed with acute appendicitis and underwent an appendectomy. As a control group, the study also included 79 non-pregnant patients who underwent appendectomy within the last 1.5 years. To ensure that the groups were similar, women in the case group were stratified according to age, and the proportions of women in the strata were determined. The women in the control group were similarly stratified. Women were randomly selected from the strata to prevent bias. Both laboratory and examination findings required for each scoring method were obtained and assessed separately for each patient. Negative appendectomy rates were evaluated according to pathology results. Categorical variables were compared using the chi-square test. A p value < 0.05 was considered to indicate significance. Receiver operator characteristic curve analysis was used to identify the best threshold value and to assess the performance of the test scores in terms of diagnosing appendicitis. RESULTS Among all scoring systems, the Tzanakis score was most efficacious at predicting appendicitis in non-pregnant women. The positive predictive value (PPV) of the Tzanakis score was 90.6%, whereas the negative predictive value (NPV) was 46.7%. The RIPASA score performed the best among the scoring systems in pregnant women. It was associated with a PPV of 94.40%, NPV of 44%, and sensitivity and specificity of 78.46% and 78.57%, respectively. CONCLUSION Although the RIPASA score can be used to efficaciously diagnose acute appendicitis in pregnant women, a specific scoring system is needed for diagnosis during the gestation period.

Abstract
Acute appendicitis is the most frequent surgical disease complicating pregnancy. Accurate diagnosis is difficult due to atypical and misleading clinical manifestations. Surgeons frequently do not know about advantages and disadvantages of different diagnostic methods applied during pregnancy. Treatment of acute appendicitis in pregnant women remains the real challenge for surgeons. There are enough researches indicating on benefits and risks of both open and laparoscopic operations. The main risk is due to fetal loss after laparoscopic procedure. Safety of diagnostic techniques and laparoscopic procedures, surgical tactics and independent risk factors of pregnancy loss are touched in the article.

Abstract
BACKGROUND Recently, laparoscopic appendectomies (LAs) have been widely performed instead of open appendectomies (OAs) during pregnancy. However, concerns about the safety of LA during pregnancy remain. This systematic review and meta-analysis aimed to evaluate the current evidence relating to the safety of LA versus OA for suspected appendicitis during pregnancy. METHODS Comprehensive literature searches were conducted using the PubMed, EMBASE, and Cochrane Library databases to identify articles describing LA versus OA in pregnancy, without restrictions regarding the publication date. The primary endpoints were fetal loss and preterm delivery. RESULTS After screening 801 studies, 22 comparative cohort studies were included in the analysis, which involved 4694 women, of whom 905 underwent LAs and 3789 underwent OAs. Fetal loss was significantly higher among those who underwent LAs compared with those who underwent OAs, and the pooled odds ratio (OR) was 1.72 (95% confidence interval [CI]: 1.22-2.42) without heterogeneity. The sensitivity analysis showed that the effect size was influenced by one of the studies, because its removal resulted in there being no significant difference between LA and OA with respect to the risk of fetal loss (OR 1.163, 95% CI: 0.68-1.99; P = 0.581). A significant difference was not evident between LA and OA with respect to preterm delivery (OR 0.76, 95% CI: 0.51-1.15), a result that did not change following the sensitivity analysis. The patients who underwent LA had shorter hospital stays (mean difference - 1.01, 95% CI: -1.61--0.41) and a lower wound infection risk (OR 0.40, 95% CI: 0.21-0.76) compared with those who underwent OA. CONCLUSION It is not reasonable to conclude that LA in pregnant women might be associated with a greater risk of fetal loss. The difference between LA and OA with respect to preterm delivery was not significant.

Abstract
OBJECTIVES This clinical study is aiming to discuss the therapeutic benefit of laparoscopic appendectomy (LA) by comparing with conventional open appendectomy (OA) in pregnancy. MATERIALS AND METHODS The clinical data of 26 pregnant women who underwent appendectomy from 2012 to 2016 was retrospectively analyzed. The variables analyzed included baseline information, operation characteristics, maternal complications, and infant health outcomes. The patients were divided in 2 LA and OA groups according to the surgical approach and their clinical characteristics were compared. RESULTS Of reported 26 patients, 7 underwent LA whereas the remaining 19 patients underwent OA. The median age of the patients was 28 years (range, 19 to 39 y). The median gestational period was 21.5 weeks (range, 5 to 33 wk). The postoperative pathology showed complicated appendicitis 7 cases. The result showed significantly shorter operation time (42.14±8.63 vs. 65.21±26.58 min, P=0.003), hospital stay (4.14±1.77 vs. 6.47±2.72 d, P=0.021), and earlier recovery of gastrointestinal function in the LA group compared with OA group. There were no maternal and fetal deaths occurred in perioperative period in both groups. CONCLUSIONS LA has not increased morbidity and mortality but displayed shorter hospital stay, operation time and recovery of gastrointestinal function to OA as well as good cosmetic results. Therefore, LA in patients with pregnancy can be considered as preferred approach in sophisticated hands without increased risks.

Abstract
The occurrence of acute appendicitis during pregnancy may pose diagnostic and therapeutic difficulties. In fact pregnancy can make the clinical diagnosis delicate and the use of morphological examinations is still subject to controversy. The debates concerning the ideal surgical approach during pregnancy continue. On the other hand, in some cases the occurrence of acute appendicitis, especially in its complicated form, which is frequent in pregnant women, exposes to obstetrical complications and an increased risk of premature delivery We aims to describe the clinical and management features of acute appendicitis in pregnant women and the maternal and neonatal outcomes and carry out a review of the literature on this topic. It is a retrospective analysis of a series of 33 cases of appendicitis in pregnant women who were diagnosed and managed, in collaboration between the departments of General and digestive surgery, Gynecology and Obstetrics and Anaesthesia at Farhat Hached Universitary Hospital Sousse Tunisia between January 2005 and December 2015. The average age of the patients was 29 (20-40). Fourteen patients were in the first trimester, twelve in the 2nd and seven in the third trimester. The main symptom was pain in the right iliac fossa. The mean delay between consultation and surgery was 2.7 days. Twenty five patients had a preoperative ultrasound. Eight of the 33 pregnant patients presented complicated appendicitis with localized or generalized peritonitis. Thirty patients underwent laparotomic appendectomy: 28 with a Mc Burney incision and 2 with a midline incision and only three patients underwent laparoscopy. Preventive tocolysis was given to 14 patients, maternal mortality was null. Twenty four pregnancies were followed until delivery: one case of premature birth and one case of preterm labor were observed. Pregnancy makes it difficult to diagnose appendicitis, which explains the high rate of complicated acute appendicitis in our series. An early treatment improves maternal and fetal outcome.

Clinical utility of magnetic resonance imaging in the evaluation of pregnant females with suspected acute appendicitis. Abdom Radiol (NY) 2018; 43:1446-1455. [PMID: 28849364 DOI: 10.1007/s00261-017-1300-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/27/2022]
Abstract
OBJECTIVES To assess the diagnostic performance of magnetic resonance imaging (MRI) in a large cohort of pregnant females with suspected acute appendicitis and to determine the frequency of non-appendiceal causes of abdominal pain identified by MRI in this population. METHODS This HIPAA compliant, retrospective study was IRB-approved and informed consent was waived. 212 MRI exams were performed consecutively on pregnant women aged 17-47 years old suspected of having acute appendicitis; eight exams were excluded and analyzed separately due to equivocal findings or lack of clinical follow up. Radiology reports for the MRI and any preceding ultrasound exams were reviewed as well as the patients' electronic medical record for surgical, pathological, or clinical follow up. RESULTS Fifteen (7.3%) of 204 MRI scans were determined to be positive for appendicitis, 14 of which were proven on surgical pathology, and one was found to have ileocecal diverticulitis. Out of the remaining 189 scans, none were subsequently shown to have acute appendicitis either surgically or based on clinical follow up. Negative predictive value (NPV) was 100% and positive predictive value was 93.3%. Sensitivity and specificity were 100% and 99.5%, respectively. Non-appendiceal findings which may have accounted for the patient's abdominal pain were seen in 91 (44.2%) of 189 scans. The most common extra-appendiceal causes of abdominal pain identified on MRI include degenerating fibroids (n = 11), significant hydronephrosis (n = 12), cholelithiasis (n = 6), and pyelonephritis (n = 3). CONCLUSION Our large study cohort of pregnant patients confirms MRI to be of high diagnostic value in the workup of acute appendicitis with 100% NPV and sensitivity and 99.5% specificity. Furthermore, an alternative diagnosis for abdominal pain in this patient population can be made in nearly half of MRI exams which are deemed negative for appendicitis.

Abstract
BACKGROUND Acute appendicitis is the most frequent abdominal condition that requires non-obstetric surgical intervention during pregnancy. This study aims to scan pregnant patients operated on for acute appendicitis to evaluate the efficiency of using the Alvarado Score (AS) for diagnosis. METHODS Our study included 48 pregnant patients who were pre-diagnosed with acute appendicitis and operated on at our department of general surgery from January 2010 to July 2016 and whose files were accessed. Fifty-three non-pregnant female patients of reproductive age who were operated on for appendicitis during the same period were included in the study as the control group. The patients in both groups were divided into two groups based on their AS total score being 7 and ≥ 7. RESULTS The mean age of the 48 pregnant patients was 28 (19-42) years, while the mean age of the 53 control patients was 31 (18-45) years. Among pregnant and non-pregnant women, about a third of patients had an AS < 7 (16 of 48 versus 18 of 53). There was no significant difference when the AS scores of both groups were compared (p = 0.947). Using pathology results as reference test, the sensitivity and specificity of the AS in pregnant women was 79 and 80%. CONCLUSIONS As a result, when the data collected by our study are evaluated, we see that pregnancy does not have a negative effect on the efficacy of AS. Therefore, the AS system can be an easy, non-invasive auxiliary diagnostic tool with high diagnosis accuracy rates that can be used in pregnant patients suspected of having acute appendicitis.

Abstract
BACKGROUND Acute appendicitis is the most common nonobstetric indication for surgical intervention during pregnancy. However, the current literature is scarce and composed of relatively small case series. We aimed to compare the presentation, management, and surgical outcomes of presumed acute appendicitis between a contemporary cohort of pregnant women and nonpregnant women of reproductive age. METHODS The study group included 92 pregnant patients who underwent appendectomy for presumed acute appendicitis at a single tertiary medical center in 2000-2014. Preoperative, operative, and postoperative clinical data were derived from medical records and compared to data for 494 nonpregnant patients of reproductive age who underwent appendectomy in 2004-2007 at the same institution. RESULTS Median age was 28 years (range 25-33) in the study group and 26 years (range 20-34) in the control group (P = 0.1). There were no between-group differences in mean white blood cell count, patient interval, hospital interval, or operative time. Preoperative abdominal ultrasound was used in a significantly higher proportion of patients in the pregnant group than in the nonpregnant group (73 and 27 %, respectively, P < 0.001) and computed tomography, in a significantly lower proportion of patients (1 vs. 16 %, respectively, P < 0.001) . The two groups had similar rates of negative appendectomy (23 and 22 %, P = 0.9), complicated appendicitis (12 and 11 %, P = 0.9), and overall postoperative complications (15 and 12 %, P = 0.3). CONCLUSIONS The clinical presentation and outcome of presumed acute appendicitis are similar in pregnant women and nonpregnant women of reproductive age. Therefore, similar perioperative management algorithms may be applied in both patient populations.

Abstract
INTRODUCTION suspected appendicitis is the most common indication for surgery in non-obstetric conditions during pregnancy and occurs in about one in 500 to one in 635 pregnancies per year. This occurs more often in the second trimester of pregnancy. Acute appendicitis is the most common general surgical problem encountered during pregnancy. METHODS a literature review on research of scientific articles, under the terms "acute appendicitis" and "pregnancy", in PubMed, Lilacs/SciELO, Scopus, Cochrane Library and Uptodate databases. RESULTS the clinical manifestations of appendicitis are similar to non-pregnant women, however, without a classic presentation, which often occurs, diagnosis is difficult and must be supported by imaging. DISCUSSION clinical diagnosis should be strongly suspected in pregnant women with classic findings such as abdominal pain that migrates to the right lower quadrant. The main purpose of imaging is to reduce delays in surgical intervention due to diagnostic uncertainty. A secondary objective is to reduce, but not eliminate, the negative appendectomy rate. Differential diagnosis of suspected acute appendicitis usually includes pathologies considered in non-pregnant people. CONCLUSION the imaging study of choice is ultrasound, MRI may be used when the former is not conclusive and, as a last resort, a CT scan can be performed. The treatment remains appendectomy by laparotomy, since the feasibility of video- assisted surgery in these cases remains controversial.

Abstract
Acute appendicitis (AA) is not uncommon during pregnancy but can be difficult to diagnose. This study evaluated the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in addition to conventional diagnostic indicators of the disease to diagnose AA during pregnancy. Age, gestational age, white blood cell (WBC) count, Alvarado scores, C-reactive protein (CRP), lymphocyte count, NLR and PLR were compared among 28 pregnant women who underwent surgery for AA, 35 pregnant women wrongly suspected as having AA, 29 healthy pregnant women, and 30 nonpregnant healthy women. Mean WBC counts and CRP levels were higher in women with proven AA than in those of control groups (all p < 0.05). Among all the groups, the median NLR and PLR were significantly different in women with proven AA (all p < 0.05). Receiver operating characteristic analysis was used to determine cut-off values for WBC count, CRP, lymphocyte count, NLR and PLR, and multiple logistic regression analysis showed that NLR and PLR used with routine methods could diagnose AA with 90.5% accuracy. Used in addition to routine diagnostic methods, NLR and PLR increased the accuracy of the diagnosis of AA in pregnant women.

Abstract
OBJECTIVE To determine the absolute and relative risk of acute appendicitis during the antepartum and postpartum periods compared with the time outside pregnancy among women of childbearing age. BACKGROUND Acute appendicitis is the most common nonobstetric surgical emergency during pregnancy. Estimates of the incidence of acute appendicitis in pregnancy remain imprecise and inconsistent. METHODS All potential fertile women aged 15 to 44 years registered within Clinical Practice Research Datalink with linkages to the Hospital Episodes Statistics between 1997 and 2012 were identified. Absolute rates of acute appendicitis were calculated during the antepartum and postpartum periods and were compared with the time outside pregnancy in terms of incidence rate ratio (IRR) using a Poisson regression model. RESULTS Among 1,624,804 women, there were 362,219 pregnancies resulting in live or stillbirths. Compared with the time outside pregnancy, the rate of acute appendicitis was 35% lower during the antepartum period [IRR, 0.65; 95% confidence interval (CI), 0.55-0.76], with the lowest rate reported during the third trimester (IRR, 0.47; 95% CI, 0.35-0.64) for all ages; no increased risk of acute appendicitis was observed in the postpartum period compared with the time outside pregnancy among women aged 15 to 34 years but an 84% increased risk for women older than 35 years (IRR, 1.84; 95% CI, 1.18-2.86). The highest and lowest rates of negative appendectomy were encountered in the second and the third trimesters, respectively. CONCLUSIONS Pregnant women are less likely to be diagnosed with acute appendicitis than nonpregnant women, with the lowest risk reported during the third trimester.

Abstract
BACKGROUND Laparoscopic appendicectomy has gained wide acceptance as an alternative to open appendicectomy during pregnancy. However, data regarding the safety and optimal surgical approach to appendicitis in pregnancy are still controversial. METHODS This was a systematic review and meta-analysis of studies comparing laparoscopic and open appendicectomy in pregnancy identified using PubMed and Scopus search engines from January 1990 to July 2011. Two reviewers independently extracted data on fetal loss, preterm delivery, wound infection, duration of operation, hospital stay, Apgar score and birth weight between laparoscopic and open appendicectomy groups. RESULTS Eleven studies with a total of 3415 women (599 in laparoscopic and 2816 in open group) were included in the analysis. Fetal loss was statistically significantly worse in those who underwent laparoscopy compared with open appendicectomy; the pooled relative risk (RR) was 1·91 (95 per cent confidence interval (c.i.) 1·31 to 2·77) without heterogeneity. The pooled RR for preterm labour was 1·44 (0·68 to 3·06), but this risk was not statistically significant. The mean difference in length of hospital stay was - 0·49 (-1·76 to - 0·78) days, but this was not clinically significant. No significant difference was found for wound infection, birth weight, duration of operation or Apgar score. CONCLUSION The available low-grade evidence suggests that laparoscopic appendicectomy in pregnant women might be associated with a greater risk of fetal loss.

Abstract
OBJECTIVE Appendicitis is the most common surgical emergency in pregnancy. Acute appendicitis is often difficult to diagnose clinically, and concerns regarding antenatal CT imaging limit its use resulting in high false negative rates at laparotomy. MRI has recently been reported as a reasonable alternative to CT imaging in cases of suspected appendicitis. Our objective was to perform a meta-analysis of recently published data regarding the utility of MR imaging in cases of antenatal suspected acute appendicitis. METHODS We searched the PubMed database using keywords 'MRI', 'appendicitis', and 'pregnancy'. Five case series describing the role of MRI in cases of antenatal appendicitis were included. The sensitivity, specificity, positive, and negative predictive values were calculated. RESULTS Two hundred twenty-nine patients were included in the study. In the first analysis in which non-diagnostic scans were excluded, the sensitivity, specificity, positive and negative predictive values of MRI for diagnosing appendicitis were 95.0%, 99.9%, 90.4%, and 99.5%, respectively. In the second analysis, which included non-diagnostic scans, the sensitivity, specificity, positive and negative predictive values were 90.5%, 98.6%, 86.3%, and 99.0%, respectively CONCLUSIONS MR imaging may be useful in cases of suspected antenatal appendicitis. Data are still limited and larger prospective studies are necessary to confirm this finding.

Abstract
BACKGROUND The aim of this study was to determine the risk factors associated with the principal outcomes in acute appendicitis during pregnancy: appendix-perforation, and maternal and fetal mortality and maternal morbidity. METHODS Fifty-two pregnant women who were diagnosed and operated upon acute appendicitis in Dicle University Hospital, Diyarbakir, Turkey were presented. RESULTS The frequency of appendicitis was higher in second trimester. On laparotomy 21 patients had perforated, 29 patients had non-perforated and 2 patients had normal appendix. Interval between symptom onset and operation was found as the only predictive variable, which was independently associated with the presence of appendiceal perforation. There was a significant difference between perforated and non-perforated patients about the rate of complications (52% vs. 17%). Gestational age (p=0.036), interval between symptom onset and operation (p=0.018) and white blood cell count (p=0.025) were the variables related with preterm labor. Tocolytic treatment after the onset of contractions could not prevent preterm labor. The rate of fetal mortality was 8%. CONCLUSIONS Presence of perforation is the only predictive factor for maternal morbidity. The aim of the surgeon should be operating the patient before perforation. An observation period may be essential in equivocal patients, but should be individualized according to duration of symptoms and findings of physical examination. The interval between the symptom onset and operation should never exceed 20 hours. Tocolytics should be ordered for the patients with delayed presentation and advanced gestational age in order to prevent preterm labor and fetal loss.
