Non-operative management of symptomatic cholelithiasis in pregnancy is associated with frequent hospitalizations

Common bile duct exploration with choledochotomy and primary repair during pregnancy: Case Report

We present a case of a woman in the second trimester of pregnancy who was admitted due to symptomatic common bile duct stones and gallstones. The patient underwent ultrasonography (US) and magnetic resonance cholangiopancreatography (MRCP) imaging, as well as a series of relevant blood tests, to establish a diagnosis. After a comprehensive assessment, simultaneous T-tube-free laparoscopic transcholedochal stone extraction and cholecystectomy were performed safely in the pregnant patient with common bile duct stones and gallstones. Postoperatively, the patient had an uneventful recovery. This case report aims to provide detailed information on the selection of treatment options for symptomatic choledocholithiasis combined with gallstones during pregnancy and to explore the feasibility and safety of performing concurrent T-tube-free laparoscopic choledochotomy for stone extraction in pregnant patients.

SAGES guidelines for the use of laparoscopy during pregnancy

BACKGROUND

When pregnant patients present with nonobstetric pathology, the physicians caring for them may be uncertain about the optimal management strategy. The aim of this guideline is to develop evidence-based recommendations for pregnant patients presenting with common surgical pathologies including appendicitis, biliary disease, and inflammatory bowel disease (IBD).

METHODS

The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Guidelines Committee convened a working group to address these issues. The group generated five key questions and completed a systematic review and meta-analysis of the literature. An expert panel then met to form evidence-based recommendations according to the Grading of Recommendations Assessment, Development, and Evaluation approach. Expert opinion was utilized when the available evidence was deemed insufficient.

RESULTS

The expert panel agreed on ten recommendations addressing the management of appendicitis, biliary disease, and IBD during pregnancy.

CONCLUSIONS

Conditional recommendations were made in favor of appendectomy over nonoperative treatment of appendicitis, laparoscopic appendectomy over open appendectomy, and laparoscopic cholecystectomy over nonoperative treatment of biliary disease and acute cholecystitis specifically. Based on expert opinion, the panel also suggested either operative or nonoperative treatment of biliary diseases other than acute cholecystitis in the third trimester, endoscopic retrograde cholangiopancreatography rather than common bile duct exploration for symptomatic choledocholithiasis, applying the same criteria for emergent surgical intervention in pregnant and non-pregnant IBD patients, utilizing an open rather than minimally invasive approach for pregnant patients requiring emergent surgical treatment of IBD, and managing pregnant patients with active IBD flares in a multidisciplinary fashion at centers with IBD expertise.

Pregnant patients undergoing cholecystectomy: nationwide assessment of clinical characteristics and outcomes

BACKGROUND

Gallstone disease in pregnancy is one of the most common indications for nonobstetrical surgery during pregnancy. National-level data on contemporary surgical practice and outcomes are limited.

OBJECTIVE

This study aimed to assess the clinical characteristics and outcomes of patients undergoing cholecystectomy during pregnancy.

STUDY DESIGN

This cross-sectional study examined the Healthcare Cost and Utilization Project's 2 nationwide databases in the United States: the National Inpatient Sample and the Nationwide Ambulatory Surgery Sample. The study population included 18,630 patients who had cholecystectomy during pregnancy from January 2016 to December 2020. The exposure was gestational age, grouped sequentially into the following 5 groups: first trimester (<14 weeks), early second trimester (14-20 weeks), late second trimester (21-27 weeks), early third trimester (28-36 weeks), and late third trimester (≥37 weeks). The main outcomes were clinical demographics, medical comorbidities, surgical information, and pregnancy characteristics and outcomes, assessed by gestational age.

RESULTS

Cholecystectomy was most common in the early second trimester (32.1%), followed by the first trimester (25.2%), late second trimester (23.1%), early third trimester (12.4%), and late third trimester (7.2%). Patients in the first-trimester group were more likely to be aged ≥35 years, to smoke, and to have acute cholecystitis, severe hyperemesis gravidarum including metabolic disturbance, pregestational diabetes, multifetal gestation, and sepsis/shock (P<.001). Patients in the early-third-trimester group were more likely to be obese and have gestational diabetes, Charlson Comorbidity Index of ≥1, premature rupture of membranes, and intrauterine growth restriction, whereas those in the late-third-trimester group were more likely to have gallstone pancreatitis, biliary colic, chorioamnionitis, gestational hypertension, preeclampsia, and severe maternal morbidity including sepsis (P<.001). At the cohort level, a laparoscopic approach was used in most cholecystectomy procedures (97.5%), and bile duct injury was uncommon (<0.1%). Delivery during the admission occurred in 0.3%, 0%, 0.6%, 17.8%, and 60.6% in the 5 gestational age groups, respectively (P<.001). Among the cases that had delivery in the early- and late-third-trimester groups, the delivery event preceded cholecystectomy in 61.4% and 86.2%, respectively, whereas both delivery and cholecystectomy occurred on the same day in 34.3% and 13.8%, respectively.

CONCLUSION

This nationwide analysis suggests that clinical and pregnancy characteristics and outcomes of patients undergoing cholecystectomy differ by pregnancy stage with a bimodal distribution. Although patients in the first and third trimesters have distinct medical conditions, more clinically significant pregnancy and maternal outcomes were found in both groups compared with patients in the second trimester.

Cholecystectomy and ERCP in pregnancy: a nationwide register-based study

OBJECTIVE

The objective was to examine the outcomes of cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) during pregnancy and compare these outcomes with those in nonpregnant women of fertile age.

SUMMARY BACKGROUND DATA

Although both laparoscopic cholecystectomy and ERCP are considered safe and feasible in pregnant patients, there is still concern and uncertainty regarding gallstone intervention during pregnancy. This study aimed to investigate outcomes in pregnant patients compared to outcomes in nonpregnant patients.

METHODS

Data on all female patients aged 18-45 years were retrieved from the Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography. The patients were divided into groups according to intervention: cholecystectomy, ERCP, or a combination thereof. Differences between pregnant and nonpregnant patients were analyzed.

RESULTS

A total of 21 328 patients were included, with 291 cholecystectomy and 63 ERCP procedures performed in pregnant patients. At the 30-day follow-up, more complications after cholecystectomy were registered for pregnant patients. However, pregnancy was not a significant risk factor for adverse events when adjusting for previous complicated gallstone disease, intraoperative complications, emergency surgery, and common bile duct stones. There were no differences in outcomes when comparing cholecystectomy among the different trimesters. ERCP had no significant effect on outcomes at the 30-day follow-up.

CONCLUSION

Cholecystectomy, ERCP, and combinations thereof are safe during pregnancy.

Laparoscopic Cholecystectomy in Pregnancy: A Seven-Year Retrospective Study From an Australian Tertiary Center

Background Cholecystectomy is the second most common non-obstetric indication for surgery during pregnancy; however, there is little recent literature specifically exploring perioperative care approaches, and a paucity of Australian data exists. This study investigates the incidence of laparoscopic cholecystectomy (LC) during pregnancy, peri-operative management, and post-operative outcomes in a single Australian tertiary center. Methods A retrospective analysis of LCs performed on pregnant patients between the ages of 16 and 50 years at a tertiary hospital between 2016 and 2023 was completed. Results Twenty-three patients underwent LC. The median gestational age was 17+4 weeks (4+3-30+6). Cases were performed in all three trimesters, with the majority in the second trimester (n=12, 52.2%). Surgery indications were recurrent biliary colic (n=11, 47.8%), acute cholecystitis (n=8, 34.8%), and gallstone pancreatitis (n=4, 17.4%). Obstetrics and Gynecology (O&G) consultations occurred in 56.5% (n=13) of cases. Fetal heart rate (FHR) was recorded perioperatively in 82.6% (n=19) of cases. Preoperative steroids were given to 40% of eligible patients. An intraoperative cholangiogram was performed in 12 (52.2%) cases, of which eight (66.7%) utilized abdominal shielding. There was no perioperative maternal mortality nor fetal loss. Surgical morbidities were pancreatitis (n=1), bile leak (n=1), and intraoperatively recognized bile duct injury (n=1). Two threatened preterm labors and five (26.3%) preterm deliveries occurred. Conclusion Performing LC in pregnancy does carry a risk of major morbidity; however, there was no mortality or fetal loss across all trimesters. The decision to perform abdominal shielding during an intraoperative cholangiogram should be approached sensitively in a case-by-case manner, given recent paradigm shifts in radiology. A multidisciplinary approach with standardized local perioperative care policies regarding procedures such as O&G consultation, perioperative steroid use, and FHR monitoring is strongly recommended.

Imaging of benign gallbladder and biliary pathologies in pregnancy

The rising incidence combined with pregnancy-related physiological changes make gallbladder and biliary pathology high on the differential for pregnant patients presenting with right upper abdominal pain. Imaging plays a crucial role in determining surgical versus non-surgical management in pregnant patients with biliary or gallbladder pathology. Ultrasound (first-line) and magnetic resonance with magnetic resonance cholangiopancreatography (second-line) are the imaging techniques of choice in pregnant patients with suspected biliary pathology due to their lack of ionizing radiation. MRI/MRCP offers an excellent non-invasive imaging option, providing detailed anatomical detail without known harmful fetal side effects. This article reviews physiological changes in pregnancy that lead to gallstone and biliary pathology, key imaging findings on US and MRI/MRCP, and management pathways.

Novel advances in surgery for Gallstone Disease

PURPOSE OF REVIEW

Examine recent advances in the treatment of patients with complex gallstone disease.

RECENT FINDINGS

Laparoscopic common bile duct exploration (LCBDE) has been shown to be an effective and safe treatment for choledocholithiasis, resulting in decreased hospital length of stay and costs when compared with ERCP plus laparoscopic cholecystectomy (LC). Novel simulator-based curricula have recently been developed to address the educational gap that has resulted in an underutilization of LCBDE. Patients with cholecystitis who are too ill to safely undergo LC have traditionally been treated with percutaneous cholecystostomy (PC). Endoscopic ultrasound (EUS) guided gallbladder drainage is a novel definitive treatment for such patients and has been shown to result in decreased complications and hospital readmissions compared to PC. The management of symptomatic gallstone disease during pregnancy has evolved over the last several decades. While it is now well established that laparoscopic procedures under general anesthesia are safe throughout a pregnancy, recent studies have suggested that laparoscopic cholecystectomy during the third trimester specifically may result in higher rates of preterm labor when compared with non-operative management. Finally, indocyanine green (ICG) fluorescence cholangiography is a novel imaging modality that has been used during laparoscopic cholecystectomy and may offer better visualization of biliary anatomy during dissection when compared with traditional intraoperative cholangiography. A number of recent technological, procedural, educational, and research innovations have enhanced and expanded treatment options for patients with complex gallstone disease.

Choledocholithiasis in Pregnancy: A Case Report

Cholelithiasis during pregnancy and the postpartum period has an incidence of 12%, with pregnancy being an important risk factor for gallstones. Patients with choledocholithiasis can experience complications, such as obstructive jaundice, cholangitis, and pancreatitis, which may be detrimental to both mother and fetus.

A case of cholelithiasis in a second-trimester pregnancy was complicated by choledocholithiasis and obstructive jaundice. Ultrasonography (US), magnetic resonance cholangiopancreatography (MRCP), along with serial blood tests, confirmed the diagnosis. Treatment was safely achieved using endoscopic retrograde cholangiopancreatography (ERCP).

In pregnancy, complicated cholelithiasis is investigated using blood tests, ultrasonography, and cholangiography. Evidence supports the use of intraoperative or endoscopic cholangiography for the management of such complicated gallstone disease in pregnancy.

Appendicitis and Cholecystitis in Pregnancy

Up to 2% of pregnant women develop a disease that requires nonobstetrical operative intervention during pregnancy. We discuss the issues unique to pregnant patients as they pertain to the presentation, diagnosis, and management of nonobstetric surgical disease, with an emphasis on 2 of the most common diseases that affect pregnant women: appendicitis and cholecystitis. Surgery has been demonstrated to be safe and effective during pregnancy, provided proper precautions are taken into account. It is the consensus of multiple professional committees and societies that no pregnant women should be delayed or denied a necessary surgery because of pregnancy.

Is It Safe to Manage Acute Cholecystitis Nonoperatively During Pregnancy?: A Nationwide Analysis of Morbidity According to Management Strategy

OBJECTIVES

To compare cholecystectomy (CCY) and nonoperative treatment (no-CCY) for acute cholecystitis in pregnancy.

SUMMARY OF BACKGROUND DATA

Current Society of Gastrointestinal and Endoscopic Surgery guidelines recommend CCY over nonoperative management of acute cholecystitis during pregnancy, and the American College of Obstetricians and Gynecologists recommend medically necessary surgery regardless of trimester. This approach has been recently questioned.

METHODS

Pregnant women admitted with acute cholecystitis were identified using the Nationwide Readmission Database 2010-2015. Propensity-score adjusted logistic regression models were used to compare CCY and no-CCY. The primary outcome was a composite measure of adverse maternal-fetal outcomes (intrauterine death/stillbirth, poor fetal growth, abortion, preterm delivery, C-section, obstetric bleeding, infection of the amniotic fluid, venous thromboembolism).

RESULTS

There were 6390 pregnant women with acute cholecystitis: 38.2% underwent CCY, of which 5.1% were open. Patients were more likely to be managed operatively in their second trimester (First 43.9%, Second 59.1%, Third 34.2%; P < 0.01). Patients managed with CCY did not differ in age, insurance, income, Charlson Comorbidity Index, diabetes or obesity when compared to no-CCY (all P > 0.05), but were less likely to have a previous C-section, gestational diabetes, preeclampsia/eclampsia or be in the third trimester (P ≤ 0.01). Risk-adjusted analyses showed that no-CCY was associated with significantly increased maternal-fetal complications during the index admission [odds ratio 3.0 (95% confidence interval 2.08-4.34), P < 0.01] and 30-day readmissions [odds ratio 1.61 (confidence interval % CI 1.12-2.32), P < 0.01].

CONCLUSIONS

Contrary to current guidelines, most pregnant women admitted in the US with acute cholecystitis are managed nonoperatively. This is associated with over twice the odds of maternal-fetal complications in addition to increased readmissions.

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.

Considering delay of cholecystectomy in the third trimester of pregnancy

INTRODUCTION

Current guidelines support laparoscopic cholecystectomy as the treatment of choice for pregnant women with symptomatic gallbladder disease, regardless of the trimester. Early intervention has remained the standard of care, but recent evidence has challenged this practice in pregnant women. We sought to compare surgical and maternal-fetal outcomes of antepartum versus postpartum cholecystectomy in New York State.

METHODS

Between 2005 and 2014, the New York Statewide Planning and Research Cooperative System (SPARCS) database was queried for patients who underwent cholecystectomy within 3 months before (antepartum cholecystectomy, APCCY: n = 82) and after (postpartum cholecystectomy, PPCCY: n = 5040) childbirth to approximate third-trimester operations. All patients who underwent cholecystectomy during pregnancy (n = 971) were extracted to evaluate inter-trimester differences. Subgroup analysis compared APCCY patients who were not hospitalized within 1 year before APCCY (n = 80) and PPCCY patients who were hospitalized within 1 year before childbirth (n = 29) for symptomatic biliary disease. Multivariable generalized linear regression models were used to characterize the association between timing of cholecystectomy and several primary outcomes: length of stay (LOS), 30-day non-pregnancy, non-delivery readmission (NPND), bile duct injury (BDI), composite maternal outcome (antepartum hemorrhage, preterm delivery, cesarean section), any complications, and fetal demise.

RESULTS

Third-trimester APCCY women had longer LOS (Ratio: 1.44, 95% CI [1.26-1.66], p < 0.0001) and greater incidence of preterm delivery (OR 2.54, 95% CI [1.37-4.43], p = 0.0019). Cholecystectomy timing was not independently associated with differences in composite maternal outcome (p = 0.1480), BDI (p = 0.2578), 30-day NPND readmission (p = 0.7579), any complications (p = 0.2506), and fetal demise (2.44% versus 0.44%, p = 0.0545). Subgroup analysis revealed no differences in any of the seven outcomes.

CONCLUSIONS

New York Statewide data suggest that although laparoscopic cholecystectomy is safe in pregnancy, delay of cholecystectomy should be discussed in the third trimester due to an increased risk for preterm delivery.

Non-obstetric surgery in pregnancy (including bowel surgery and gallbladder surgery)

Non-obstetric surgery during pregnancy is required in 0.75-2% of pregnancies. Physiologic changes during pregnancy, both hormonal and anatomic, can have interactions with surgery and anesthesia. Indication, timing as well as risks of anesthesia and surgery should be considered in surgical decision making. The health status of the mother should always be put first. A preoperative multidisciplinary approach, also including an obstetrician and neonatologist, is mandatory. Delay in diagnosis and treatment carry risks of complications in all septic visceral indications. Considerations should be individualized.

Association of complicated gallstone disease in pregnancy and adverse birth outcomes

BACKGROUND

Complicated gallstone disease (CGD) is a common condition requiring intervention during pregnancy to avert adverse birth outcomes (ABO).

METHODS

Cohort study using the California OSHPD 2007-2014 database. Records of pregnant patients were analyzed for gallbladder calculus within four months of delivery. Biliary system interventions were evaluated as the primary exposure.

RESULTS

Of 7,597 patients, those with CGD had a greater likelihood of biliary system procedures than those with uncomplicated gallstone disease (36.6% vs. 2.5%, p < 0.001). Patients with CGD also had increased odds of ABO (OR 2.02, 95% CI, 1.48-2.76). Compared to patients without biliary system procedures, those with interventions for gallstones had an OR of 3.46 (95% CI, 2.48-4.82) for ABO. After adjustment, biliary system intervention for CGD had an even greater risk of ABO (OR 4.26, 95% CI, 2.86-6.35).

CONCLUSIONS

The risk of ABO is significantly increased in women with CGD and intervention for gallstones.

Abdominal pain and vomiting during pregnancy due to cholesterolosis

We present a 22-year-old pregnant woman at 15 weeks of gestation, with abdominal pain and vomiting. We demonstrate that diagnosis and treatment of vomiting and abdominal pain in pregnancy can be difficult. Therefore, involvement of other medical specialists is important when common treatments fail. Cholesterolosis can cause symptoms similar to those caused by cholelithiasis. Controversial to gallstones, identification of cholesterolosis by ultrasound is hard. Cholecystectomy is the only effective treatment option for cholesterolosis and can be performed safely during pregnancy. Cholecystectomy in pregnancy should be considered if, despite atypical symptoms, gallbladder disease is suspected and other diagnoses are ruled out. This may reduce recurrent symptoms, hospital admissions, exposure to harmful drugs and obstetric complications.

Emergency general surgery in pregnancy

It is often that the acute care surgeon will be called on to evaluate the pregnant patient with abdominal pain. Most of the diagnostic and management decisions regarding pregnant patients will follow the usual tenets of surgery; however, there are important differences in the pregnant patient to be aware of to avoid pitfalls which can lead to complications for both mother and fetus. This review hopes to describe the most common emergencies facing the surgeon caring for the pregnant patient and the latest management options.

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.

Changing management of gallstone-related disease in pregnancy - a retrospective cohort analysis

OBJECTIVES

Gallstone-related disease is the second most common non-obstetric cause, following appendicitis, for acute abdomen in pregnancy. This study aimed to investigate treatment strategies, changes over time and outcome.

MATERIALS AND METHODS

All consecutive patients with symptomatic gallstone-related disease during pregnancy admitted to Skane University hospital in Lund and Malmö 2001-2015 were analysed retrospectively. Information regarding the patient, pregnancy and fetus/child was recorded. The material was analysed by dividing it into two equal time periods and by comparing conservative management and surgical intervention.

RESULTS

We included 96 patients with 97 pregnancies. The age was 30 (26-34) years and BMI 28 (24-31). Median length of pregnancy at first admission was 23 (13-31) weeks. The three most common diagnoses were biliary colic (n = 63), cholecystitis (n = 22) and acute pancreatitis (n = 16). Conservative treatment was practiced in 62 (64%) patients and intervention in 35 (36%). Conservatively treated patients were admitted later during pregnancy (week 26 (20-33) versus 17 (10-22), p < .001). Surgically treated patients had a longer total length of stay (all admissions) than conservatively treated patients (p = .001), less readmissions (p = .001) and equal birth outcome. Surgical intervention was more common in the later time period (48% versus 22%, p = .011). Of the conservatively treated patients, 56% were subjected to surgical intervention within 2 years after delivery.

CONCLUSIONS

We found that intervention was more common in the later time period, with good results concerning safety, and less readmissions. A majority of the conservatively treated patients had surgical intervention within two years after delivery. Our results support surgical intervention in pregnancy.

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.

Gallstones

Gallstones grow inside the gallbladder or biliary tract. These stones can be asymptomatic or symptomatic; only gallstones with symptoms or complications are defined as gallstone disease. Based on their composition, gallstones are classified into cholesterol gallstones, which represent the predominant entity, and bilirubin ('pigment') stones. Black pigment stones can be caused by chronic haemolysis; brown pigment stones typically develop in obstructed and infected bile ducts. For treatment, localization of the gallstones in the biliary tract is more relevant than composition. Overall, up to 20% of adults develop gallstones and >20% of those develop symptoms or complications. Risk factors for gallstones are female sex, age, pregnancy, physical inactivity, obesity and overnutrition. Factors involved in metabolic syndrome increase the risk of developing gallstones and form the basis of primary prevention by lifestyle changes. Common mutations in the hepatic cholesterol transporter ABCG8 confer most of the genetic risk of developing gallstones, which accounts for ∼25% of the total risk. Diagnosis is mainly based on clinical symptoms, abdominal ultrasonography and liver biochemistry tests. Symptoms often precede the onset of the three common and potentially life-threatening complications of gallstones (acute cholecystitis, acute cholangitis and biliary pancreatitis). Although our knowledge on the genetics and pathophysiology of gallstones has expanded recently, current treatment algorithms remain predominantly invasive and are based on surgery. Hence, our future efforts should focus on novel preventive strategies to overcome the onset of gallstones in at-risk patients in particular, but also in the population in general.

Episode of Familial Mediterranean Fever-Related Peritonitis in the Second Trimester of Pregnancy Followed by Acute Cholecystitis: Dilemmas and Pitfalls

BACKGROUND

Differential diagnosis of acute abdomen in pregnant patients is one of the greatest challenges for the clinician. Occurrence of Familial Mediterranean Fever (FMF) paroxysm of peritonitis and acute cholecystitis during pregnancy is a unique clinical entity that leads to serious diagnostic and therapeutic dilemmas.

CASE REPORT

We present the case of a 33-year-old Armenian patient at 16 weeks' gestational age with a history of FMF, who was admitted twice within 1 month with acute abdomen. The first episode was attributed to FMF and successfully treated conservatively with colchicine. The second episode was diagnosed as acute cholecystitis and led to emergent laparoscopic cholecystectomy and lysis of peritoneal adhesions from previous FMF attacks. The patient presented an uneventful postoperative clinical course and had a normal delivery of a healthy infant at the 39th week of gestation.

CONCLUSIONS

Pregnant patients with acute abdomen should be evaluated with open mind. To the best of our knowledge, this is the first published report of the coexistence of 2 different causes of acute abdomen during pregnancy. Meticulous history and thorough physical, laboratory, and radiologic examination are the keys to reach a correct diagnosis. Treatment of pregnant patients with acute abdomen should be individualized. Administration of colchicine should be continued during conception, pregnancy, and lactation in patients with FMF history. Laparoscopic intervention in pregnant patients with surgical abdomen such as acute cholecystitis is the optimal method of treatment.

Management of gallstones and its related complications

The majority of gallstone patients remain asymptomatic; however, interest toward the gallstone disease is continuing because of the high worldwide prevalence and management costs and the development of gallstone symptoms and complications. For cholesterol gallstone disease, moreover, a strong link exists between this disease and highly prevalent metabolic disorders such as obesity, dyslipidemia, type 2 diabetes, hyperinsulinemia, hypertriglyceridemia and the metabolic syndrome. Information on the natural history as well as the diagnostic, surgical (mainly laparoscopic cholecystectomy) and medical tools available to facilitate adequate management of cholelithiasis and its complications are, therefore, crucial to prevent the negative outcomes of gallstone disease. Moreover, some risk factors for gallstone disease are modifiable and some preventive strategies have become necessary to reduce the onset and the severity of complications.
