Appendicitis and cholecystitis in pregnancy. Clin Obstet Gynecol. 2009;52:586-596. [PMID: 20393411 DOI: 10.1097/grf.0b013e3181c11d10]

Mini-Laparoscopic Cholecystectomy During the Late Second and Third Trimesters of Pregnancy

BACKGROUND

Mini-laparoscopic cholecystectomy (MLC) reduces abdominal wall injury and has the advantage of not altering the surgical principles of conventional laparoscopic cholecystectomy. Our team recently decided to extend the indications for mini-laparoscopy to pregnant women requiring cholecystectomy in the late second and third trimesters when significant uterine height is a potential difficulty.

METHODS

From January 2022, all patients who underwent MLC after five months of pregnancy were included in the analysis. Operative, postoperative, and perinatal outcomes were retrospectively collected.

RESULTS

Ten patients underwent MLC between 24 and 32 weeks of gestation. The mean operative time was 73 ± 24 minutes. Only one minor intraoperative complication was observed. The mean postoperative pain, quality of life, and cosmetic satisfaction at the first postoperative visit were 1.8 ± 0.9, 9.1 ± 0.8, and 9.5 ± 0.8, respectively. Finally, all patients had an uncomplicated vaginal delivery. No preterm delivery or fetal loss occurred.

CONCLUSIONS

These preliminary results suggest that the mini-laparoscopy could be used safely in selected pregnant women requiring cholecystectomy even after five months of gestation. By preserving the abdominal wall as much as possible, MLC may be of particular interest in this particular case, when the patient's abdominal wall could potentially be subjected to severe secondary stress in the event of vaginal delivery.

Misdiagnosis of Acute Appendicitis Cases in the Emergency Room

Acute appendicitis (AA) is one of the most frequent surgical emergencies, especially in pediatric populations, with its misdiagnosis in emergency settings presenting significant health risks. This misdiagnosis leads to various complications, such as delayed treatment or unnecessary surgeries. Factors such as age, gender, and comorbidities contribute to diagnostic errors, leading to complications such as peritonitis and increased negative appendectomy rates. This underscores the importance of accurate clinical assessment and awareness of common pitfalls, such as cognitive biases and over-reliance on laboratory tests. This review delves into the prevalence of AA misdiagnosis, its health burden, and the challenges inherent in the diagnostic process. It scrutinizes the effectiveness of different diagnostic approaches, including clinical assessment and imaging techniques. The treatment paradigms for AA are also explored, focusing on surgical interventions and the potential of conservative treatments using antibiotics. The review underscores the criticality of precise diagnosis in preventing adverse outcomes and ensuring effective treatment.

Operative vs Nonoperative Management of Acute Cholecystitis During the Different Trimesters of Pregnancy

Importance

Acute cholecystitis (AC) management during pregnancy requires balancing the risk of pregnancy loss or preterm delivery (adverse pregnancy outcomes [APOs]) with or without surgery. Guidelines recommend cholecystectomy across trimesters; however, trimester-specific evidence on the risks of AC and its management is lacking.

Objective

To assess cholecystectomy frequency in pregnant people with AC, compare the rates of APOs in pregnant people with or without AC, and compare the rates of APOs in people with AC who did or did not undergo cholecystectomy.

Design, Setting, and Participants

This retrospective, population-based cohort study used data for pregnant people with AC from the IBM MarketScan Commercial Claims and Encounters Database from January 1, 2007, to December 31, 2019, and a propensity score-matched cohort of pregnant people without AC. Trimester status (first [T1], second [T2], and third [T3]), APOs, and cholecystectomy were defined by administrative claims. Data were analyzed from October 2021 to July 2022.

Exposures

Pregnant patients with or without AC. Pregnant patients with AC who did or did not receive cholecystectomy.

Main Outcomes and Measures

The main outcomes were cholecystectomy during pregnancy and APOs (ie, preterm delivery and pregnancy loss). Pregnant patients with and without AC were compared to assess the association of AC with risk of APOs. Propensity score inverse-probability weighting was used to calculate treatment-associated APO risk among patients with 1-year follow-up.

Results

The study included 5759 pregnant patients with AC (mean [SD] age, 30.1 [6.6] years) and 23 036 controls (mean [SD] age, 29.9 [6.7] years) after propensity score matching. Among 3426 pregnant patients with AC and 1-year follow-up, 1182 (34.5%) underwent cholecystectomy during the pregnancy (684 [41.7%] presenting with AC in T1, 404 [40.4%] in T2, and 94 [12.0%] in T3). Acute cholecystitis during pregnancy, irrespective of treatment, was associated with higher odds of APO compared with no AC during pregnancy across all trimesters (odds ratio [OR], 1.69 [95% CI, 1.54-1.85]). Compared with nonoperative management, receipt of surgery was associated with lower odds of APOs across all trimesters (OR, 0.75 [95% CI, 0.63-0.87]), in T1 (OR, 0.81 [95% CI, 0.66-1.00]), in T2 (OR, 0.71 [95% CI, 0.50-1.00]), and in T3 (OR, 0.45 [95% CI, 0.28-0.70]).

Conclusions and Relevance

In this study, cholecystectomy was associated with lower risk of APO in patients with AC across all trimesters, with the greatest benefit in T3. However, only 34.5% overall and 12.0% of patients in T3 had a cholecystectomy. These findings support guidelines recommending cholecystectomy during pregnancy and should inform decision-making discussions. Greater guideline adherence and surgery use, especially in T3, may represent an opportunity to improve outcomes for pregnant people with AC.

General Surgery During Pregnancy and Gynecologic Emergencies

Nonobstetrical surgical emergencies can occur throughout pregnancy but are often difficult to diagnose due to the physiologic and anatomical changes that occur during pregnancy. Medical providers should have insight into these changes and be familiar with options for the diagnosis and management of common nonobstetrical surgical emergencies, such as appendicitis, cholecystitis, and small bowel obstruction. Surgeons should also be aware of obstetrical emergencies, such as ectopic pregnancy and severe vaginal bleeding, which may be life threatening to mother and the fetus. Intraoperatively, surgeons should be familiar with minimally invasive approaches for surgical diseases and special anesthetic considerations for pregnant patients.

Imaging of Acute Abdominopelvic Pain in Pregnancy and Puerperium-Part II: Non-Obstetric Complications

Emergency imaging in pregnancy and puerperium poses unique challenges both for clinicians and radiologists, requiring timely and accurate diagnosis. Delay in treatment may result in poor outcomes for both the patient and the foetus. Pregnant and puerperal patients may present in the emergency setting with acute abdominopelvic pain for various complications that can be broadly classified into obstetric and non-obstetric related diseases. Ultrasonography (US) is the primary diagnostic imaging test; however, it may be limited due to the patient's body habitus and the overlapping of bowel loops. Computed tomography (CT) carries exposure to ionising radiation to the foetus, but may be necessary in selected cases. Magnetic resonance imaging (MRI) is a valuable complement to US in the determination of the etiology of acute abdominal pain and can be used in most settings, allowing for the identification of a broad spectrum of pathologies with a limited protocol of sequences. In this second section, we review the common non-obstetric causes for acute abdominopelvic pain in pregnancy and post partum, offering a practical approach for diagnosis and pointing out the role of imaging methods (US, MRI, CT) with the respective imaging findings.

Nonobstetric Surgical Emergencies in Pregnancy

In this article, we discuss the major nonobstetric surgical complications that may occur in pregnancy. We highlight specific diagnostic challenges particularly with imaging modalities and radiation considerations for the fetus. Topics covered in this article include appendicitis, intestinal obstruction, gallstone disease, hepatic rupture, perforated peptic ulcer, mesenteric venous thrombosis, splenic artery aneurysm rupture, and aortic dissection.

[Laparoscopic appendectomy for acute appendicitis in pregnancy]

The review is devoted to the role of laparoscopic appendectomy in surgical management of acute appendicitis in pregnancy. We analyzed reviews, prospective and retrospective studies in the PubMed, Google, the Springer Link online library, the Cochrane Systematic Review databases. The results of laparoscopic and traditional treatment of acute appendicitis in pregnant women were assessed. We analyzed clinical, epidemiological features in these patients, differential diagnosis of acute appendicitis in pregnant women, indications and contraindications for endoscopic treatment, features of laparoscopic procedures. Comparative assessment of laparoscopic and open surgeries for acute appendicitis in pregnant women was carried out. We also estimated the influence of surgical treatment of acute appendicitis on subsequent course of pregnancy.

Challenging Obstetrical Management in Generalized Peritonitis during Pregnancy

Acute abdomen in pregnancy represents a diagnostic and therapeutic challenge, despite the current advances in modern medicine, since the typical symptoms and altered laboratory parameters mimic normal pregnancy. Acute appendicitis is the most common nonobstetric surgical emergency during pregnancy, with an incidence of 1 per 500-2000 pregnancies. Delayed diagnosis and reluctance to operate on a pregnant woman predispose to adverse maternal and fetal outcomes. The elective termination of pregnancy or interventions to prolong it in the presence of appendicitis is controversial. We present a case of a 38-year-old Caucasian woman, G2P0, admitted to the Obstetric Emergency Department at 13 4/7 weeks of gestation with a primary complaint of severe nausea and vomiting associated with progressive diffuse abdominal pain which had started 7 days before. After the difficulty of inherent differential diagnosis, she was diagnosed with generalized peritonitis due to acute perforated appendicitis. Prompt exploratory laparotomy with appendectomy and drainage of multiple abscesses were performed. Conservative obstetrical management was assumed, with subsequent periodic monitoring of the fetal focus. Due to abdominal compartment syndrome, the abdomen was left open for 4 days. After 7 days in the intensive care unit, recovery was favorable, pregnancy remained uneventful, and a healthy full-term baby was born 27 weeks later. This case represents a successful example of how the cooperation of the obstetrics and general surgery teams and the decision of conservative obstetrical management in the surgical environment contributed to optimizing maternal health, achieving the best obstetrical outcome.

State of the Art in Hepatic Dysfunction in Pregnancy

Hepatic dysfunction in pregnant women is always challenging for the obstetrician, as the spectrum of hepatic abnormalities can be very large and have various implications, both for mother and fetus. There is a diagnostic and therapeutic polymorphism of hepatic dysfunction in pregnancy and insufficient knowledge related to the etiopathogenesis and epidemiology of this disease. The clinical forms of hepatic dysfunction encountered in pregnancy can vary from liver diseases related to pregnancy (e.g., HELLP syndrome, intrahepatic cholestasis, hyperemesis gravidarum, or acute fatty liver of pregnancy) to de novo ones occurring in pregnancy, and pre-existing liver disease (cholelithiasis, Budd-Chiari syndrome, and cirrhosis). We performed a systematic literature search over 10 years. The review protocol assumed a search of two databases (PubMed®/MEDLINE and Web of Science Core Collection). The strategy regarding the management of these diseases involves multidisciplinary teams composed of different specialists (obstetricians, gastroenterologists and anesthetists) from specialized tertiary centers. Despite the improving prognosis of pregnant women with liver diseases, the risk of maternal-fetal complications remains very high. Therefore, it is necessary to ensure careful monitoring by a multidisciplinary team and to inform the patients of the potential risks.

Updated Evaluation of Laparoscopic vs. Open Appendicectomy During Pregnancy: A Systematic Review and Meta-Analysis

To explore the updated evaluation about the obstetrical and perioperative outcomes of laparoscopic appendicectomy (LA) for pregnancy appendicitis compared with open appendicectomy (OA). Two reviewers independently searched the PubMed, the Cochrane Central Register of Controlled Trials, EMBASE, and Web of Science databases to screen eligible studies up to December 2020. Only clinical researches, no < 10 cases for LA and OA group were included. Twenty retrospective studies with 7,248 pregnant women, evaluating LA and OA in surgical and obstetrical outcomes, were included. The weighted mean difference (WMD) with 95% CI and odds ratio (OR) was used to compare continuous and dichotomous variables. It seems LA was connected with significantly shorter hospital time and lower wound infection [mean difference (MD), −0.57 days; 95% CI, −0.96 to −0.18; p = 0.004 and OR, 0.34; 95% CI, 0.18 to 0.62; p = 0.0005, respectively]. The incidence of fetal loss after LA was higher than OA (OR,1.93; 95% CI, 1.39–2.69; p < 0.0001). It was almost similar in the rate of preterm delivery (OR, 0.80; 95% CI, 0.48 to 1.34; p = 0.40) and other perioperative and obstetrical complications (p > 0.05). Our results indicated that the occurrence of fetal loss after LA should not be ignored. Caution, skillful operation, and thoroughly informed consent about the advantages and disadvantages of laparoscopy are necessary.

Laparoscopic treatment for appendicitis during pregnancy: Retrospective cohort study

Background

Acute appendicitis is the most frequent non-obstetric surgical emergency during pregnancy. The benefits of laparoscopy during pregnancy are well known, but complications can occur, and these can affect both the mother and/or the foetus.We present results of laparoscopic surgical treatment of acute appendicitis in pregnant women, analysing the occurrence of adverse postoperative, obstetric and foetal outcomes and reviewing literature.

Materials and methods

Retrospective observational study on pregnant women with a preoperative diagnosis of acute appendicitis.

Results

n = 63, mean age 28.4 years, average gestational age of 17.7 weeks (3-30 weeks). 6.4 % exploratory laparoscopies, 92 % laparoscopic appendectomies and one right colectomy were performed. Conversion rate was 3.2 %. When symptoms begun within 48 hours prior to surgery, a perforated appendicitis was found in 11 %; whereas when the time from symptom onset to surgery was greater than or equal to 48 hours, it was evident in 31 % of the cases (p 0.008). The only independent variable associated with the presence of postoperative complications was symptom duration prior to surgery greater than or equal to 48 hours (OR 4.8; 95 % CI 1.1-16.2; p 0.04). Seven minor and 2 mayor postoperative complications were observed. Patients with complications spent, on average, twice as many days hospitalized (p < 0.001); and had 8 times more risk of preterm delivery (p 0.03). Obstetric complications were more frequent in pregnant women operated during the first trimester. Foetal mortality was 1.6 %.

Conclusion

Surgical morbidity of acute appendicitis in pregnant women is linked to the delay in the diagnosis and treatment of the inflammatory condition. Laparoscopic appendectomy during pregnancy is not exempt from postoperative, obstetric and foetal complications. It is necessary to standardize the definitions of "complication" in order to collate reliably the outcomes presented in the literature.

Mediterranean diet and breastfeeding reduce the risk of gallstone in women

OBJECTIVE: This study aimed to determine the effect of nutrition style and breastfeeding on the formation of gallstone in women. METHODS: 50 women age from 40 to 69 included in the study. A questionnaire in which the participant’s general information questioned, their anthropometric values recorded, and the Mediterranean diet (MD) adherence scale included, was filled in by the face-to-face interview method. RESULTS: Body mass index (BMI), waist circumference (WC), diastolic blood pressure (DBP), fasting blood glucose (FBG), and serum C-reactive protein (CRP) values were higher in those with gallstones than in the control group. The total breastfeeding time and MD adherence scores were higher in the control group. It determined that there was a negative relationship between breastfeeding time with DBP and CRP. It found that an increase in BMI and WC increases the probability of gallstones. It found that an increase in the duration of breastfeeding and MD adherence score decreases the probability of the gallstones. CONCLUSION: Breastfeeding and Mediterranean diet reduce the risk of gallstones in women.

Association of laparoscopy and laparotomy with adverse fetal outcomes: a retrospective population-based case-control study

BACKGROUND

This study aimed to evaluate fetal adverse outcomes of laparoscopy and laparotomy in pregnant women to determine the safety of these surgical approaches.

METHODS

This was a retrospective nationwide case-control study of women who became pregnant for the first time between 2000 and 2012 in Taiwan. The case (with adverse fetal outcomes) and control groups comprised 208,604 and 417,124 participants, respectively. Participants who underwent appendectomy, cholecystectomy, ovarian cystectomy, or myomectomy were treated with either laparoscopy or laparotomy. A conditional logistic regression model was used to calculate the odds ratios (ORs) for adverse fetal outcomes.

RESULTS

The laparotomy and laparoscopy groups comprised 632 and 536 patients, respectively. Women who underwent laparoscopy had a significantly higher risk of adverse fetal outcomes (adjusted OR [AOR] = 2.33; 95% CI 1.66-2.99) than those who underwent laparotomy. Adverse fetal outcomes were found to be significantly associated with laparoscopy among women aged 20-39 years (AOR = 2.30; 95% CI 1.70-3.31). Regarding surgical indication, unlike laparotomy, laparoscopic cholecystectomy and appendectomy were not associated with adverse fetal outcomes. However, laparoscopic myomectomy and ovarian surgeries were associated with a higher incidence of adverse fetal outcomes than the laparotomy group (AOR = 2.29 [95% CI 1.57-3.35, p < 0.0001] and AOR = 2.52 [95% CI 1.58-4.04, p = 0.0001], respectively).

CONCLUSIONS

Pregnant women who underwent laparoscopic surgery experienced significantly more adverse fetal outcomes than those who underwent laparotomy. Therefore, pregnant women undergoing either laparotomy or laparoscopy should be informed of the risk of adverse fetal outcomes.

Surgical trends in the management of acute cholecystitis during pregnancy

BACKGROUND

Since 2007, clinical practice guidelines by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) recommend early surgical management with laparoscopic cholecystectomy for pregnant women with symptomatic gallbladder disease regardless of trimester. However, little is known about practice patterns in the management of pregnant patients with acute cholecystitis. This study aims to examine nationwide trends in the surgical management of acute cholecystitis, as well as their impact on clinical outcomes during pregnancy.

METHODS

The National Inpatient Sample was queried for all pregnant women diagnosed with acute cholecystitis between January 2003 and September 2015. After applying appropriate weights, multivariate regression analysis adjusted for patient- and hospital-level characteristics and quantified the impact of discharge year (2003-2007 versus 2008-2015) on cholecystectomy rates and timing of surgery. Multivariate regression analysis was also used to examine the impact of same admission cholecystectomy and its timing on maternal and fetal outcomes.

RESULTS

A total of 23,939 pregnant women with acute cholecystitis satisfied our inclusion criteria. The median age was 26 years (interquartile range: 22-30). During the study period, 36.3% were managed non-operatively while 59.6% and 4.1% underwent laparoscopic and open cholecystectomy, respectively. After adjusting for covariates, laparoscopic cholecystectomy was more commonly performed after 2007 (odds ratio [OR] 1.333, p < 0.001). Furthermore, time from admission to surgery was significantly shorter in the latter study period (regression coefficient -0.013, p < 0.001). Compared to non-operative management, laparoscopic cholecystectomy for acute cholecystitis was significantly associated with lower rates of preterm delivery, labor, or abortion (OR 0.410, p < 0.001). Each day that laparoscopic cholecystectomy was delayed significantly associated with an increased risk of fetal complications (OR 1.173, p < 0.001).

CONCLUSIONS

This nationwide study exhibits significant trends favoring surgical management of acute cholecystitis during pregnancy. Although further studies are still warranted, early laparoscopic cholecystectomy should be considered in pregnant patients with acute cholecystitis.

Reasons for Undesirable Pregnancy Outcomes among Women with Appendicitis: The Experience of a Tertiary Center

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.

Gallbladder and Biliary Disease in Pregnancy

Diseases of the gallbladder and biliary tract are extremely common in developed nations. Because of the physiology of pregnancy, their incidence increases during gestation. This article represents a review of the existing literature on the entire spectrum of biliary disease. The physiology, clinical presentation, and diagnostic evaluation of a variety of conditions are reviewed. Historical and contemporary data regarding pregnancy implications and treatment options are discussed.

Sepsis in Pregnancy: Recognition and Resuscitation

The normal physiologic changes of pregnancy complicate evaluation for sepsis and subsequent management. Previous sepsis studies have specifically excluded pregnant patients. This narrative review evaluates the presentation, scoring systems for risk stratification, diagnosis, and management of sepsis in pregnancy. Sepsis is potentially fatal, but literature for the evaluation and treatment of this condition in pregnancy is scarce. While the definition and considerations of sepsis have changed with large, randomized controlled trials, pregnancy has consistently been among the exclusion criteria. The two pregnancy-specific sepsis scoring systems, the modified obstetric early warning scoring system (MOEWS) and Sepsis in Obstetrics Score (SOS), present a number of limitations for application in the emergency department (ED) setting. Methods of generation and subsequently limited validation leave significant gaps in identification of septic pregnant patients. Management requires consideration of a variety of sources in the septic pregnant patient. The underlying physiologic nature of pregnancy also highlights the need to individualize resuscitation and critical care efforts in this unique patient population. Pregnant septic patients require specific considerations and treatment goals to provide optimal care for this particular population. Guidelines and scoring systems currently exist, but further studies are required.

Laparoscopic appendectomy versus open appendectomy for suspected appendicitis during pregnancy: a systematic review and updated meta-analysis

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.

Is the laparoscopic approach a safe choice for the management of acute appendicitis in pregnant women? A meta-analysis of observational studies

INTRODUCTION

Acute appendicitis is a common and serious situation during pregnancy, because of the increased risk of fetal loss and perforation in the third trimester, as well as a diagnostic difficulty. During recent years laparoscopic approach has been introduced to clinical practice with encouraging results. The purpose of this meta-analysis is to compare the surgical and obstetrical outcomes between laparoscopic and open appendectomy during pregnancy.

MATERIALS AND METHODS

MEDLINE, SCOPUS, Clinicaltrials.gov, CENTRAL and Google Scholar were searched for studies reporting on postoperative outcomes between laparoscopic and open appendectomy during pregnancy. The random effects model (DerSimonian-Laird) was used to calculate pooled effect estimates when high heterogeneity was encountered, otherwise the fixed-effects (Mantel-Haenszel) model was implemented.

RESULTS

Twenty-one studies that enrolled 6276 pregnant women are included in the present meta-analysis. Of these women, 1963 underwent laparoscopic appendectomy and 4313 underwent an open appendectomy. Women who underwent laparoscopic appendectomy demonstrated an increase in fetal loss risk, while neonates of women that underwent open appendectomy presented decreased Apgar score at five minutes after birth. All the rest outcomes were similar between the two groups. The time that each study took place seemed to affect the comparison of birth weight and postoperative hospital stay between the two groups.

CONCLUSION

Laparoscopic appendectomy seems to be a relatively safe therapeutic option in pregnancy when it is indicated. Thus, it should be implemented in clinical practice, always considering the experience of the surgeon in such procedures. Nevertheless, the need of new studies to enhance this statement remains crucial.

Minimally invasive gynecologic surgery in the pregnant patient: considerations, techniques, and postoperative management per trimester

PURPOSE OF REVIEW

Nonobstetric surgery is performed in 1 : 200 to 1 : 500 of pregnant women in the United States annually. Previously, many argued that laparoscopy was contraindicated during pregnancy because of concerns for uterine injury and fetal malperfusion. Because surgeons have gained more experience with laparoscopy, it has become the preferred treatment modality for many surgical diseases in the gravid patient.

RECENT FINDINGS

Specific preoperative considerations, intraoperative techniques, and postoperative management per trimester will be reviewed to optimize patient and surgical outcomes.

SUMMARY

The advantages of laparoscopic surgery are similar for pregnant and nonpregnant women. Surgery during pregnancy should minimize risks to both the fetus and the mother. Whenever a pregnant woman undergoes nonobstetric surgery, consultations among her surgical team are important to coordinate management. Both anatomic and physiologic changes related to pregnancy may require modifications in management. Surgeons must be aware of considerations, techniques, and postoperative management used for pregnant patients to optimize outcomes for both the fetus and mother.

Major liver resection in pregnancy: three cases with different etiologies and review of the literature

BACKGROUND

Major liver resection during pregnancy is extremely rare. When required, the associated physiologic and anatomic changes pose specific challenges and greater risk for both mother and fetus Materials and methods: Three cases of major liver resection during pregnancy due to different etiologies are presented. The relevant literature is reviewed and discussed.

RESULTS

We present three cases of major liver resection due to giant liver hemangioma with Kasabach-Merrit syndrome, giant hydatid cyst, and intrahepatic cholangiocarcinoma, at gestational week (GW) 17, 19, and 30, respectively. All patients had an uneventful postoperative course, continued the pregnancy and gave birth at GW 38.

CONCLUSION

Major liver resection can be performed safely during pregnancy. A multidisciplinary team of surgeons, anesthesiologists and gynecologists, in a highly experienced tertiary hepatobiliary center, should be involved.

Evaluation of management and surgical outcomes in pregnancies complicated by acute cholecystitis

OBJECTIVE

To evaluate the management of pregnancies complicated by acute cholecystitis (AC) and determine whether pregnant women are more likely to have medical and surgical complications.

METHODS

We carried out a population-based matched cohort study using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 2003 to 2011. Pregnant women with AC were age matched to non-pregnant women with AC on a 1:5 ratio. Management and outcomes were compared using descriptive analysis and conditional logistic regression.

RESULTS

There were 11,835 pregnant women admitted with AC who were age matched to 59,175 non-pregnant women. As compared to non-pregnant women, women with AC were more commonly managed conservatively, odds ratio (OR) 6.1 (5.8-6.4). As compared to non-pregnant women, pregnant women with AC more commonly developed sepsis [OR 1.4 (1.0-1.9)], developed venous thromboembolism [OR 8.7 (4.3-17.8)] and had bowel obstruction [OR 1.3 (1.1-1.6)]. Among pregnant women with AC, surgical management was associated with a small but significant increased risk of septic shock and bile leak.

CONCLUSION

AC, in the context of pregnancy, is associated with an increased risk of adverse outcomes. Although the literature favors early surgical intervention, pregnancies with AC appear to be more commonly managed conservatively with overall comparable outcomes to surgically managed AC. Conservative management may have a role in select pregnant women with AC.

Pregnancy outcomes following nonobstetric surgery during gestation: a nationwide population-based case-control study in Taiwan

Background

Whether nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion or adverse delivery outcomes is still unclear.

Methods

We performed a retrospective case-control study using a Longitudinal Health Insurance Database (LHID 2000) containing claim-data of 1 million randomly selected beneficiaries. We compared the incidences and estimated the adjusted odds ratios (aOR) with 95% confidence interval (95% CI) for spontaneous abortion, adverse delivery outcomes, cesarean delivery, and prolonged hospital stay to determine the risk of adverse outcomes in women who had nonobstetric surgery during gestation as compared to those who did not have any surgery during gestation.

Results

After exclusion, we were left with 114,852 delivery and 3999 abortion cases in our study; and 462 (0.39%) of them had nonobstetric surgery under general or regional anesthesia during pregnancy. The leading surgeries were repair of cervical os (33.12%), appendectomy (17.32%), ovarian surgeries (13.64%), and fixation of fractured bone (8.01%).The risk of spontaneous abortion (4.23% vs. 2.43%, aOR:1.53; 95% CI: 1.01–2.31), antepartum hemorrhage (7.14% vs. 2.83%, aOR: 2.51; 95% CI: 1.74–3.61), pre-eclampsia/eclampsia (2.60% vs. 1.01%, aOR: 2.35; 95% CI: 1.30–4.23), gestational diabetes (2.38% vs. 0.69%, aOR: 3.12; 95% CI: 1.69–5.78), prematurity (9.06 vs. 4.90%, aOR: 3.31; 95% CI: 2.54–4.31), cesarean section (43.55% vs. 33.76%, aOR: 1.41; 95% CI: 1.17–1.71), and prolonged hospital stay (1.82% vs. 5.91%, aOR: 3.23; 95% CI: 2.16–4.83) were higher in those women who had nonobstetric surgery after adjusting for age and comorbidities.

Conclusions

Nonobstetric surgery during gestation were associated with a higher risk of spontaneous abortion, adverse delivery outcomes, cesarean section, and prolonged hospital stay.

Hydrosalpinx with acute abdominal pain during the third trimester of pregnancy: A case report

Background

Acute abdomen in pregnancy is a unique clinical challenge. We report a rare case of hydrosalpinx presenting as acute abdomen in the third trimester of pregnancy in the absence of infection and hormonal treatment.

Case

A 38-year-old Caucasian woman (gravida 4, para 3), at an estimated 29 weeks of a spontaneous singleton pregnancy, presented to the emergency department with severe abdominal pain in the right lower quadrant, which had been present for three days. Magnetic resonance imaging (MRI) demonstrated a right-sided hydrosalpinx. It was successfully treated with conservative treatment and the patient delivered vaginally at term without complication.

Conclusion

Hydrosalpinx should be considered as one of the differential diagnoses for acute abdomen during pregnancy. A multidisciplinary approach is recommended, with a careful work-up, due to the risks to both fetus and mother.

Suspicion of appendicitis in pregnant women: emergency evaluation by sonography and low-dose CT with oral contrast

OBJECTIVES

To evaluate non-intravenously enhanced low-dose computed tomography with oral contrast (LDCT) for the assessment of pregnant women with right lower quadrant pain, when magnetic resonance imaging (MRI) is not immediately available.

METHODS

One hundred and thirty-eight consecutive pregnant women with acute abdominal pain were admitted in our emergency centre. Thirty-seven (27%) of them, with clinical suspicion of acute appendicitis, underwent abdominal ultrasonography (US). No further examination was recommended when US was positive for appendicitis, negative with low clinical suspicion or showed an alternative diagnosis which explained the clinical presentation. All other patients underwent LDCT (<2.5 mSv). Standard intravenously enhanced CT or MRI was performed when LDCT was indeterminate.

RESULTS

Eight (22%) of 37 US exams were reported normal, 25 (67%) indeterminate, 1 (3%) positive for appendicitis, 3 (8%) positive for an alternative diagnosis. LDCT was obtained in 29 (78%) patients. It was reported positive for appendicitis in 9 (31%), for alternative diagnosis in 2 (7%), normal in 13 (45%) and indeterminate in 5 (17%). Further imaging (standard CT or MRI) showed appendicitis in 2 of these 5 patients, was truly negative in 1, indeterminate in 1 and falsely positive in 1. An appendicitis was confirmed at surgery in 12 (32%) of the 37 patients. The sensitivity and the specificity of the algorithm for appendicitis were 100% (12/12) and 92% (23/25), respectively.

CONCLUSIONS

The proposed algorithm is very sensitive and specific for detection of acute appendicitis in pregnant women; it reduces the need of standard CTs when MRI is not available as second-line imaging.

KEY POINTS

• In pregnant women, US is limited by an important number of indeterminate results • Low-dose CT can be used after an inconclusive US for the diagnosis of appendicitis in pregnant women • An algorithm integrating US and low-dose CT is highly sensitive and specific for appendicitis in pregnant women.

Outcomes of Gallstone Disease during Pregnancy: a Population-based Data Linkage Study

BACKGROUND

Gallstone disease is a leading indication for non-obstetric abdominal surgery during pregnancy. There are limited whole population data on maternal and neonatal outcomes. This population-based study aims to describe the outcomes of gallstone disease during pregnancy in an Australian setting.

METHODS

Linked hospital, birth, and mortality data for all women with singleton pregnancies in New South Wales, Australia, 2001-2012 were analysed. Exposure of interest was gallstone disease (acute biliary pancreatitis, gallstones with/without cholecystitis). Outcomes including preterm birth (spontaneous and planned), readmission, morbidity and mortality (maternal and neonatal) were compared between pregnancies with and without gallstone disease. Adjusted risk ratios (aRRs) and 99% confidence intervals were estimated using modified Poisson regression and adjusted for maternal and pregnancy factors.

RESULTS

Among 1 064 089 pregnancies, 1882 (0.18%) had gallstone disease. Of these, 239 (12.7%) had an antepartum cholecystectomy and 1643 (87.3%) were managed conservatively. Of those managed conservatively, 319 (19.0%) had a postpartum cholecystectomy. Gallstone disease was associated with increased risk of preterm birth (aRR 1.3, 99% CI 1.1, 1.6), particularly planned preterm birth (aRR 1.6, 99% CI 1.2, 2.1), maternal morbidity (aRR 1.6, 99% CI 1.1, 2.3), maternal readmission (aRR 4.7, 99% CI 4.2, 5.3), and neonatal morbidity (aRR 1.4, 99% CI 1.1, 1.7). Surgery was associated with decreased risk of maternal readmission (aRR 0.4, 99% CI 0.2, 0.7).

CONCLUSIONS

Gallstone disease during pregnancy was associated with adverse maternal and neonatal outcomes. Most women with gallstone disease during pregnancy are managed conservatively. Surgical management was associated with decreased risk of readmission.

Laparoscopy in the second and third trimesters of pregnancy for abdominal surgical emergencies

OBJECTIVE

To assess complications and outcomes of pregnancies following laparoscopic abdominal surgery during the second and third trimesters of pregnancy.

MATERIAL AND METHODS

Retrospective single-center study of 23 cases of laparoscopic surgery in the second or third trimesters of pregnancy between January 2005 and May 2016.

RESULTS

The laparoscopies were performed between 15 and 33 weeks of gestation, a mean of 23 weeks+2 days, with 6 cases in the 3rd trimester. The operations were: 11 cholecystectomies, 6 appendectomies, 1 intestinal occlusion (volvulus on a gastric band), 3 adnexal torsions, 1 ovarian cyst and 1 paratubal cyst with torsion. No secondary laparotomy was required. The postoperative courses were favorable in most cases. However, 3 appendectomies were complicated, one by chorioamnionitis and miscarriage at 20½ weeks of gestation and 2 by right iliac fossa abscesses requiring percutaneous radiological drainage, one of these women delivered a healthy term baby and the other had chorioamnionitis and preterm delivery at 34 weeks, followed by neonatal death.

CONCLUSION

Laparoscopy can be safely performed for surgical indications in the second and third trimesters of pregnancy. In case of abdominal symptoms, a timely diagnosis is required to decide whether or not to operate and imaging should not be withheld particularly in case of suspected appendicitis which has a high risk of complications.

The course and outcomes of complicated gallstone disease in pregnancy: Experience of a tertiary center

Objective:

To evaluate the course and outcomes of pregnant patients with complicated gallstone disease and to reveal the experience of a tertiary center.

Materials and Methods:

The records of 92.567 patients were evaluated using searches for diagnoses with the terms of pregnant, pregnancy, gallstone, cholecystitis, cholangitis, choledocholithiasis, pancreatitis, and endoscopic retrograde cholangiopancreatography in pregnancy in the hospital database. Patients’ age, week of gestation, parity, body mass index, definitive diagnosis, attack episodes, treatment modalities, and obstetric and neonatal complications were evaluated.

Results:

Overall, 59 women were diagnosed as having complicated gallstone disease in pregnancy. Acute cholecystitis was the most commonly diagnosed complicated gallbladder disease (62.7%). Cholecystectomy was performed in 15 women during gestation. Perinatal outcomes were as follows: one (1.7%) maternal death, 4 (6.8%) preterm deliveries, 5 (8.5%) low-birth-weight fetuses, and 1 (1.7%) missed abortion were encountered. No fetal abnormalities were encountered.

Conclusion:

A significant proportion of women experience biliary disease during pregnancy. Herein, we presented our clinical experience because the diagnosis, course, and management of complicated gallstone disease in pregnancy is complicated.

Laparoscopic surgery in pregnancy

Each year, roughly 2% of pregnant women will undergo non-obstetrical abdominal surgery. Appendicitis, symptomatic cholelithiasis and adnexal masses are some of the common diagnoses encountered. Pregnancy poses challenges in the diagnosis and surgical management of these conditions for several reasons. Since the 1990’s, laparoscopic surgery has gained popularity and in the past few years has become the standard of care for pregnant women with surgical pathologies. The advantages of laparoscopic surgery include shorter hospital stay, lower rates of wound infection, and decreased time to bowel function. This brief review discusses key points in laparoscopic surgery during pregnancy and highlights studies comparing laparoscopic and open approaches in common surgical conditions during pregnancy.

The Pregnant Patient: Assessment and Perioperative Management

Pathologic changes can occur during pregnancy requiring diagnostic tests and procedures. A preoperative assessment and perioperative planning are essential. Normal physiologic changes include increased cardiac output and decreased functional residual capacity. Perioperative care should follow American Congress of Obstetricians and Gynecologists guidelines. Anesthetic concerns include desaturation during periods of apnea, aspiration, difficult intubation, friable nasal tissue, decreased MAC, and hypotension and/or decreased uterine perfusion from the uterus. Anesthesia and medications must be individualized and given only as needed. Limit exposure to multiple drugs and monitor for fetal wellbeing and premature labor per consultation and guidelines.

Update on the management of non-obstetric acute abdomen in pregnant patients

Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology. The aim of this paper is to perform a review and update on the diagnosis and treatment of non-obstetric acute abdomen in pregnancy.

Abdominal emergencies during pregnancy

Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

Laparoscopic appendectomy and cholecystectomy versus open: a study in 1999 pregnant patients

BACKGROUND

When pregnant patients require surgery, whether to perform an operation open or laparoscopic is often debated. We evaluated the impact of laparoscopy for common general surgical problems in pregnancy to determine safety and trends in operative approach over time.

METHODS

Pregnant patients undergoing appendectomy or cholecystectomy were identified using the National Surgical Quality Improvement Program (NSQIP) database. We analyzed demographics, operative characteristics, and outcomes. Univariate comparison and multivariate regression analysis (MVA) were performed adjusting for confounding factors: age, body mass index (BMI), diabetes, and smoking, and an additional MVA was performed for perforated cases.

RESULTS

A total of 1999 pregnant patients between 2005 and 2012 were evaluated. Of 1335 appendectomies, 894 were performed laparoscopically (LA) and 441 open (OA). For 664 cholecystectomies, 606 were laparoscopic (LC) and 58 open (OC). There were no deaths. For LA versus OA, patient characteristics were not different {age: 27.7 vs. 28.2 years, p = 0.19; diabetes: 1.8 vs. 0.9%, p = 0.24; smoking: 19 vs. 16.1%, p = 0.2} except for BMI (27.9 vs. 28.4 kg/m(2); p = 0.03). LA had shorter operative times (ORT), length of stay (LOS), and fewer postoperative complications compared to OA. In MVA, difference between approaches remained statistically significant for ORT (<0.0001), LOS (<0.01), and wound complications (<0.01). MVA was performed for perforated cases alone: LA had equal ORT (p = 0.19) yet shorter LOS (p = <0.001). The majority of LA were performed in the last 4 years versus the first 4 years (61 vs. 39%, p < 0.001). For LC versus OC, patient characteristics were not different: age (28.3 vs. 28.7 years; p = 0.33), BMI (31.4 vs. 33.2 kg/m(2), p = 0.25), diabetes (2.8 vs. 3.5%, p = 0.68), and smoking (21.1 vs. 25.9%, p = 0.4). LC had a shorter ORT, LOS, and fewer postoperative complications than OC. In MVA, the difference between approaches remained statistically significant for ORT (<0.0001), LOS (<0.0001), and minor complications (<0.01). In MVA for cholecystitis with perforation, no difference was seen for LOS, ORT, or postoperative complications (p > 0.05). The percentage of LC cases appeared to increase over time (89 vs. 93%, p = 0.06).

CONCLUSION

While fetal events are unknown, LA and LC in pregnant patients demonstrated shorter ORT, LOS, and reduced complications and were performed more frequently over time. Even in perforated cases, laparoscopy appears safe in pregnant patients.

Surgical management of acute cholecystitis

BACKGROUND

Acute cholecystitis occurs in approximately 1% of patients with known gallstones. It presents as a surgical emergency and usually requires hospitalisation for treatment. It is associated with significant morbidity and mortality, particularly in the elderly. Cholecystectomy is advocated for acute cholecystitis; however, the timing of cholecystectomy and the value of the additional treatments have been a matter of debate. This review examines the available evidence regarding the optimal surgical management of patients with acute cholecystitis.

METHODS

A literature search was performed on the MEDLINE, EMBASE and WHO International Clinical Trials Registry Platform, databases for English language publications. The MeSH headings 'cholecystitis', 'acute', 'gallbladder', 'inflammation', 'surgery', 'cholecystectomy', 'laparoscopic', 'robotic', 'telerobotic' and 'computer-assisted' were used.

RESULTS

Data from eight randomised controlled trails and three population-based analyses show that early cholecystectomy for acute cholecystitis performed on the index admission is safe and not associated with increased conversion rates or morbidity in comparison to conservative treatment followed by elective cholecystectomy. Delaying cholecystectomy increases readmissions for gallstone-related events, complications, hospital stay and mortality in the elderly. Early cholecystectomy is also more cost-effective. Randomised trials addressing antibiotic use in acute cholecystitis suggest that antibiotics should be stopped on the day of cholecystectomy. Insufficient trials have been performed to address the optimal analgesia regime post cholecystectomy. Similarly, a lack of trials on intraoperative cholangiography and management of common bile duct stones in patients with acute cholecystitis means that treatment of concomitant bile duct stones should be based on institutional expertise and resource availability. As regards acute cholecystitis in elderly and high-risk patients, case series and retrospective studies would suggest that cholecystectomy is more effective and of lower mortality than percutaneous cholecystostomy. There is not enough evidence to support the routine use of robotic surgery, single-incision laparoscopic cholecystectomy or natural orifice transluminal endoscopic surgery (NOTES) in the treatment of acute cholecystitis.

CONCLUSIONS

Trial evidence would favour a policy of early laparoscopic cholecystectomy following admission with acute cholecystitis. The optimal approach to support early cholecystectomy is suggested but requires evidence from further randomised trials.

Abdominal surgery in pregnancy--an interdisciplinary challenge

BACKGROUND

Abdominal operations are performed during ca. 2% of all pregnancies. They represent an unusual situation not only for the patient, but also for the involved surgeons and anesthesiologists. Appendectomy, followed by cholecystectomy are the two most common types of operation performed during pregnancy. Special questions arise with regard to the peri- and intraoperative management and the optimal surgical approach.

METHOD

This review is based on pertinent articles retrieved by a selective search in the PubMed database.

RESULTS

The question of laparoscopy versus laparotomy during pregnancy has been addressed to date only in case series and a few meta-analyses. Two meta-analyses have shown a significantly higher rate of miscarriage after laparoscopic, compared to open, appendectomy (relative risk [RR] 1.91, 95% confidence interval [CI] 1.31-2.77). The risk of preterm birth is also somewhat higher after laparoscopic appendectomy according to one meta-analysis on this subject (RR 1.44, 95% CI 0.78-1.76), but significantly lower according to another meta-analysis (2.1% vs. 8.1%, p<0.0001). For cholecystectomy, laparoscopy was associated with a lower miscarriage rate than laparotomy (1 in 89 cases, versus 2 in 69 cases), but with a somewhat higher preterm birth rate (6 in 89 cases, versus 2 in 69 cases). Delay or non-performance of surgery in a patient with appendicitis or cholecystitis can lead to additional hospitalizations, a higher miscarriage rate, premature rupture of the membranes, and preterm birth.

CONCLUSION

Laparoscopy in experienced hands is safe even during pregnancy, with the recognized advantages of minimally invasive surgery, yet it carries a higher miscarriage rate than laparotomy, with a comparable preterm birth rate. Before surgery, patients should be thoroughly informed about the operation they are about to undergo and the advantages and disadvantages of the available surgical approaches.

Location of the appendix at the third trimester of pregnancy: A new approach to old dilemma

The aim of this study was to determine the location of the appendix at the third trimester of pregnancy as there are conflicting results in literature. Distances from the base of the appendix were measured intra-operatively to the anterior iliac spine (A), symphysis pubis (B) and the xyphoid process (C). The same measurements were taken from McBurney's point on the abdominal wall (A1, B1 and C1). In the allocated 21 pregnant and 18 non-pregnant women, distance A and B were 10.3 ± 0.9 cm and 18.3 ± 3.2 cm in pregnant and 6.7 ± 0.9 cm and 13.2 ± 0.9 cm in non-pregnant women (p < 0.001), respectively. Distance C was shorter in pregnant women (14.7 ± 2.5 cm vs. 23.8 ± 1.9, p < 0.001). Conversely, distance C1 was longer in pregnant women (30.3 ± 3.0 vs. 24.8 ± 5.1 cm, p = 0.004). This study provides evidence that the appendix moves cranially late in the course of the pregnancy. Therefore, McBurney's point cannot be used as a reference point to localise the appendix at the third trimester of pregnancy.

Impact of appendicitis during pregnancy: no delay in accurate diagnosis and treatment

BACKGROUND

Acute appendicitis during pregnancy may be associated with serious maternal and/or fetal complications. To date, the optimal clinical approach to the management of pregnant women suspected of having acute appendicitis is subject to debate. The purpose of this retrospective study was to provide recommendations for prospective clinical management of pregnant patients with suspected appendicitis.

METHOD

Case records of all pregnant patients suspected of having appendicitis whom underwent appendectomy at our hospital between 1990 and 2010 were reviewed.

RESULTS

Appendicitis was histologically verified in fifteen of twenty-one pregnant women, of whom six were diagnosed with perforated appendicitis. Maternal morbidity was seen in two cases. Premature delivery occurred in two out of six cases with perforated appendicitis cases and two out of six cases following a negative appendectomy. Perinatal mortality did not occur.

CONCLUSION

Both (perforated) appendicitis and negative appendectomy during pregnancy are associated with a high risk of premature delivery. Clinical presentation and imaging remains vital in deciding whether surgical intervention is indicated. We recommend to cautiously weigh the risks of delay until correct diagnosis with associated increased risk of appendiceal perforation and the risk of unnecessary surgical intervention. Based upon current literature, we recommend clinicians to consider an MRI following an inconclusive or negative abdominal ultrasound aiming to improve diagnostic accuracy to reduce the rate of negative appendectomies. Accurate and prompt diagnosis of acute appendicitis should be strived for to avoid unnecessary exploration and to aim for timely surgical intervention in pregnant women suspected of having appendicitis.
