Laparoscopy for appendicitis and cholelithiasis during pregnancy: a new standard of care

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.

Adverse Fetal Outcomes and Maternal Mortality Following Nonobstetric Abdominopelvic Surgery in Pregnancy: A Systematic Review and Meta-analysis

OBJECTIVE

To quantify the absolute risks of adverse fetal outcomes and maternal mortality following nonobstetric abdominopelvic surgery in pregnancy.

SUMMARY BACKGROUND DATA

Surgery is often necessary in pregnancy, but absolute measures of risk required to guide perioperative management are lacking.

METHODS

We systematically searched MEDLINE, EMBASE, and EvidenceBased Medicine Reviews from January 1, 2000, to December 9, 2020, for observational studies and randomized trials of pregnant patients undergoing nonobstetric abdominopelvic surgery. We determined the pooled proportions of fetal loss, preterm birth, and maternal mortality using a generalized linear random/mixed effects model with a logit link.

RESULTS

We identified 114 observational studies (52 [46%] appendectomy, 34 [30%] adnexal, 8 [7%] cholecystectomy, 20 [17%] mixed types) reporting on 67,111 pregnant patients. Overall pooled proportions of fetal loss, preterm birth, and maternal mortality were 2.8% (95% CI 2.2-3.6), 9.7% (95% CI 8.3-11.4), and 0.04% (95% CI 0.02-0.09; 4/10,000), respectively. Rates of fetal loss and preterm birth were higher for pelvic inflammatory conditions (eg, appendectomy, adnexal torsion) than for abdominal or nonurgent conditions (eg, cholecystectomy, adnexal mass). Surgery in the second and third trimesters was associated with lower rates of fetal loss (0.1%) and higher rates of preterm birth (13.5%) than surgery in the first and second trimesters (fetal loss 2.9%, preterm birth 5.6%).

CONCLUSIONS

Absolute risks of adverse fetal outcomes after nonobstetric abdom- inopelvic surgery vary with gestational age, indication, and acuity. Pooled estimates derived here identify high-risk clinical scenarios, and can inform implementation of mitigation strategies and improve preoperative counselling.

Surgical treatment of adrenal tumors during pregnancy

While most adrenal tumors are identified incidentally and are non-functional, hormone-secreting tumors can cause morbidity and mortality. Hemodynamic lability and hypertension in pregnancy are associated with worse maternal and fetal outcomes. Achieving a diagnosis of hormone excess due to adrenal tumors can be clinically more difficult in the gravid patient due to normal physiologic alterations in hormones and symptoms related to pregnancy. This review focuses on some nuances of the diagnostic work-up, perioperative care, and surgical management of adrenally-mediated cortisol excess, primary aldosteronism, and pheochromocytoma and paraganglioma in the pregnant patient.

[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.

Management of Complicated Appendicitis During Pregnancy in the US

IMPORTANCE

Data are sparse regarding the optimal treatment for complicated appendicitis during pregnancy.

OBJECTIVE

To compare nonoperative and operative management in complicated appendicitis during pregnancy.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted using National Inpatient Sample data from between January 2003 and September 2015. This database approximates a 20% stratified sample of US inpatient hospital discharges. Included individuals were pregnant women discharged with the diagnosis of complicated appendicitis. Data were analyzed from February 2020 through February 2022.

EXPOSURES

Study patients were categorized into 3 groups: those with successful nonoperative management, failed nonoperative management with delayed operation, or immediate operation for complicated appendicitis.

MAIN OUTCOMES AND MEASURES

Clinical outcomes, including maternal infectious complications and perinatal complications, hospital length of stay, and total hospital charges.

RESULTS

Among 8087 pregnant women with complicated appendicitis (median [IQR] age, 27 [22-32] years), nonoperative management of complicated appendicitis was successful among 954 patients (11.8%) and failed among 2646 patients (32.7%), who underwent delayed operation; 4487 patients (55.5%) underwent immediate operation. In multivariate analysis, successful nonoperative management was associated with higher odds of amniotic infection (odds ratio [OR], 4.35; 95% CI, 2.22-8.53; P < .001) and sepsis (OR, 1.52; 95% CI, 1.10-2.11; P = .01) compared with immediate operation, while there was no significant difference in preterm delivery, preterm labor, or abortion. However, failed nonoperative management that required delayed operation was associated with higher odds of preterm delivery, preterm labor, or abortion compared with immediate operation (OR, 1.45; 95% CI, 1.24-1.68; P < .001). Immediate operation was associated with decreased hospital charges compared with nonoperative management that was successful (regression coefficient [RC], 0.09; 95% CI, 0.07-0.11; P < .001) and that failed (RC, 0.12; 95% CI: 0.11-0.14; P < .001). In subgroup multivariate logistic regression analysis, each day in delay to surgery was associated with an increase in odds of preterm delivery, preterm labor, or abortion by 23% (OR, 1.23; 95% CI, 1.18-1.29; P < .001).

CONCLUSIONS AND RELEVANCE

This study found that immediate operation for complicated appendicitis in pregnant women was associated with lower odds of maternal infectious complications without higher odds of perinatal or other maternal complications compared with successful nonoperative management. Failed nonoperative management was associated with worse clinical outcomes.

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.

Association Between Trimester and Outcomes after Cholecystectomy During Pregnancy

BACKGROUND

Conventional philosophy promotes the second trimester as the ideal time during pregnancy for cholecystectomy. However, literature supporting this belief is sparse. The purpose of this study is to examine the association of trimester and clinical outcomes after cholecystectomy during pregnancy.

STUDY DESIGN

The National Inpatient Sample was queried for pregnant women who underwent cholecystectomy between October 2015 and December 2017. Patients were categorized by trimester. Multivariable logistic and continuous outcome regression models were used to evaluate the association of trimester and outcomes, including maternal and fetal complications, length of stay, and hospital charges. The primary outcome was any complication-a composite of specific clinical complications, each of which were designated as secondary outcomes.

RESULTS

A total of 819 pregnant women satisfied our inclusion criteria. Of these, 217 (26.5%) were in the first trimester, 381 (47.5%) were in the second trimester, and 221 (27.0%) were in the third trimester. Median age was 27 years (interquartile range: 23-31 years). Compared with the second trimester, cholecystectomy during the first trimester was not associated with higher rates of complications (adjusted odds ratio [AOR] 0.88, 95% confidence interval [CI]: 0.47-1.63, p = 0.68). However, cholecystectomy during the third trimester was associated with a higher rate of preterm delivery (AOR 7.20, 95% CI 3.09-16.77, p < 0.001) and overall maternal and fetal complications (AOR 2.78, 95% CI 1.71-4.53, p < 0.001). Compared with the second trimester, the third trimester was associated with 21.3% higher total hospital charges (p = 0.003).

CONCLUSIONS

Our results suggest that cholecystectomy can be performed in the first trimester without significantly increased risk of maternal and fetal complications, compared to the second trimester. In contrast, cholecystectomy during pregnancy should not be delayed until the third trimester.

A 27-Year-Old Primigravida with a Right Renal Cell Carcinoma Removed at 30 Weeks of Gestation by Robot-Assisted Retroperitoneoscopic Partial Nephrectomy

BACKGROUND Large renal tumors during pregnancy are rare findings (0.07-0.1%). Current guidelines recommend surgical removal. This surgery should be carefully planned in an interdisciplinary team and involves special risks for mother and fetus. This report describes a case of a 27-year-old primigravida woman with a right renal cell carcinoma involving the lower pole of the kidney, which was removed at 30 weeks of gestation by robot-assisted retroperitoneoscopic partial nephrectomy (RARPN). CASE REPORT The patient was referred by the treating obstetrician with a newly diagnosed right lower pole renal mass of 6×4 cm in greatest diameter extending deeply into the parenchyma. No metastasis or enlarged lymph nodes were described in subsequent magnetic resonance tomography. Clinical and laboratory examinations documented a healthy mother and fetus. A right-sided RARPN was advised and planned by an interdisciplinary team of treating physicians (gynecologists, oncologists, and urologists). The surgery was conducted under general anesthesia with an obstetrician on stand-by. Surgery was performed without any complications (operation time 95 min, renal-ischemia time 15 min, and negligible blood loss) and histopathology confirmed the diagnosis of a chromophobe renal cell carcinoma. Further follow-up consultations showed regular wound healing and normal progression of pregnancy, and the patient gave birth to a healthy child at term. Follow-up examinations of the patient were uneventful. CONCLUSIONS This case shows that RARPN can be a safe and effective surgical procedure for partial nephrectomy during pregnancy, where surgery is performed in a specialist center and by an interdisciplinary experienced surgical team. It seems to offer advantages and better risk profile over the laparoscopic approach.

The diagnostic accuracy of ultrasound in the diagnosis of acute appendicitis in pregnancy

Objective: Clinically suspected appendicitis is the most common nonobstetric surgical problem encountered in pregnancy. The diagnosis of appendicitis is hampered by equivocal symptoms during pregnancy. Ultrasonography (US) remains, as a rule, the imaging test of choice for the diagnosis of clinically suspected appendicitis during pregnancy and other imaging tools such as computed tomography (CT) or magnetic resonance imaging (MRI) are usually avoided. We evaluated the accuracy of US in the diagnosis of appendicitis during pregnancy.Methods: The clinical and sonographic findings of all pregnant women (n = 90), who underwent appendectomy between January 2005 and December 2017 at our institution, were retrospectively reviewed, analyzed, and compared to the clinical and sonographic findings similarly obtained for a control group of nonpregnant women matched for age and date of surgery (±6 months). The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of ultrasonic findings were calculated and compared between groups as well as within the three pregnancy trimesters.Results: The mean age of the patients was 31.3 ± 0.4. Right lower quadrant pain was present in almost all patients (99%). The sole imaging modality used in our study cohort was US. Among nonpregnant controls, CT scan was primarily used on more occasions (53.3%) compared to US (45.6%). Nonpregnant women underwent significantly more laparoscopies compared to pregnant women (83.3 versus 45.6%, p < .001). The rate of negative appendectomy was higher in pregnant women (31.1 versus 10%, p = .002). Among pregnant women operated there was a higher rate of inconclusive or negative imaging (43.3 versus 11.1%, p < .001). The rate of perforated appendix at surgery was similar in both groups (6.7 and 4.4%, respectively, p = .75).Conclusions: Ultrasonography (US) is of mediocre accuracy for the diagnosis of acute appendicitis in pregnant patients beyond the first trimester of pregnancy. Thirty percent of pregnant women with suspected appendicitis are futilely operated. Given the low yield of US, a second-line imaging should be considered in cases of inconclusive US before surgery.

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.

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.

Obstetrical outcomes following laparoscopy during pregnancy: a retrospective case-control study

PURPOSE

To evaluate pregnancy outcome of patients who undergo laparoscopy during pregnancy.

METHODS

A retrospective case-control study, conducted in a single university-affiliated tertiary care medical center, comparing pregnancy outcomes of women who underwent laparoscopy during pregnancy to women without operations during pregnancy. The study group (n = 232) included all pregnant women who underwent a single laparoscopic surgery during pregnancy (4-28 weeks of gestation) which culminated in delivery between 2006 and 2017; this study group was matched to a control group (n = 463) without surgical intervention during pregnancy, in a 2:1 ratio by maternal age, parity, and multiple gestation.

RESULTS

The main pregnancy outcomes included preterm birth, cesarean section, small for gestational age (≤ 10 percentile), and Apgar score of less than 7 in 5 min. Laparoscopy during pregnancy was associated with an increased risk for cesarean section (32.3% vs. 24.6%, adjusted OR = 1.9, CI 1.2-3.1, p = 0.011). We found no difference between the groups with regard to other outcomes, including rates of preterm birth (12.1% vs. 10.4%, adjusted OR = 1.3, CI 0.64-2.72, p = 0.451). In a subgroup analysis of the study group, various perioperative parameters such as operation duration, hospitalization length, and others, did not correlate with adverse pregnancy outcome.

CONCLUSIONS

Laparoscopy during pregnancy may be associated with an increased rate of cesarean section. We did not find an increase in any other pregnancy or neonatal complication. Different perioperative parameters did not appear to predict adverse pregnancy outcome.

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.

Laparoscopic appendectomy is safe and feasible in pregnant women during second trimester: A retrospective study in a top-level Chinese center

Acute appendicitis (AA) is the most common nonobstetric surgical emergency during pregnancy. According to the current guidelines and meta-analyses, traditional open appendectomy (OA) is still recommended for pregnant patients over laparoscopic appendectomy (LA), which might be associated with higher rates of fetal loss. Previous studies and experiences indicated that LA might be safe in the second trimester of pregnancy. The current study aimed to evaluate the safety and feasibility of LA in pregnant women during the second trimester.At our institution, a retrospective study was conducted with pregnant patients who underwent LA or OA during the second trimester between January 2016 and August 2018.A total of 48 patients were enrolled. Of them, 12 were managed with laparoscopy and 36 with the open approach. We found that the LA group had higher BMIs than the OA group (4.0 ± 4.3 vs 21.5 ± 2.9, P = .031). The financial results showed that the average daily medical costs for patients who underwent LA was higher than those who underwent OA (444 ± 107 US$ vs 340 ± 115 US$, P = .009), while the total cost of hospitalization was comparable between the 2 approaches. The perioperative and obstetric outcomes were comparable between LA and OA. In each group, only 1 patient had fetal loss. No "Yinao" was found in any of the patients in the LA group.In this study, with the proven advantages of the laparoscopic techniques, LA was found to be safe and feasible for pregnant women during the second trimester.

Consensus Statement of the Italian Polispecialistic Society of Young Surgeons (SPIGC): Diagnosis and Treatment of Acute Appendicitis

Background: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA.Methods: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations.Results: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.

Laparoscopic surgery for non-obstetric acute abdomen in pregnancy: A retrospective case series review

BACKGROUND

Laparoscopic techniques have been used during pregnancy by obstetricians since the 1970's, primarily to diagnose and treat ectopic and heterotopic pregnancies. Pregnancy was considered as an absolute contraindication to laparoscopy by surgeons as recently as 1991, and a few still doubt the safety of minimal access in gravid patients. When an emergent operation is indicated, the surgery should not be withheld on the sole basis of patient's gravid state. On the contrary, the alleviation of maternal disease is thought to take priority because the health of the foetus is dependant on the mother.

MATERIALS AND METHODS

This is a retrospective study of a case series of 18 obstetric patients who presented with non-obstetric causes of acute abdomen requiring surgical intervention. Ultrasonography and magnetic resonance imaging (MRI) along with other laboratory investigations were carried out to reach the diagnosis. Laparoscopic surgery was considered as the modality of treatment. All the patients were given the necessary care post-surgery and were followed up till parturition to look for any complications.

RESULTS

The data were analysed considering the presentation, diagnostic variations and the surgical modifications statistically.

CONCLUSION

The decision of surgery should be prompt and should be weighed against complications of conserving the patient. Due to the diagnostic limitations of ultrasonography, MRI should be coupled to confirm the diagnosis. Laparoscopy offers less analgesic requirements and shorter hospital stay. The operative time is highly subjective to the experience and training of the surgeon and the laparoscopic set-up itself.

[Acute appendicitis during pregnancy]

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

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.

A successful combined laparoscopic cholecystectomy and laparoscopic exploration of common bile duct for acute gangrenous cholecystitis and choledocholithiasis during pregnancy: A case report

•

Complicated gallstone disease during pregnancy can be successfully managed by combined laparoscopic cholecystectomy and exploration of common bile duct through trans-cystic duct approach.

•

This approach is safe and can cure cholecystitis and choledocholithiasis in one goal.

•

This approach avoids ionizing radiation to the developing fetus.

Introduction

Choledocholithiasis during pregnancy is relatively uncommon but it can be life-threatening. Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) poses the risk of ionizing radiation exposure to the developing fetus. Other strategies are thus needed to tackle this problem.

Presentation of case

A 38-year-old 8 weeks’ pregnant lady presented with acute onset of right upper quadrant pain. Ultrasonography showed features of acute cholecystitis and choledocholithiasis, which was later confirmed by magnetic resonance cholangiogram. Emergency combined laparoscopic cholecystectomy (LC) and laparoscopic exploration of common bile duct (Lap ECBD) were performed. Lap ECBD through trans-cystic duct approach was adopted. The patient recovered uneventfully and was discharged on postoperative day 4. A healthy baby boy was delivered at 40 weeks’ gestation without developmental problem.

Conclusion

Lap ECBD avoided ionizing radiation for choledocholithiasis during pregnancy, and can combined with LC as an effective minimally invasive procedure for complicated gallstone disease.

Cholecystectomy During the Third Trimester of Pregnancy: Proceed or Delay?

BACKGROUND

Current guidelines suggest that cholecystectomy during the third trimester of pregnancy is safe for both the woman and the fetus. However, no population-based study has examined this issue. The aim of this analysis was to compare the results of cholecystectomy during the third trimester of pregnancy with outcomes in women operated on in the early postpartum period in a large population.

METHODS

The California Office of Statewide Health Planning and Development database was queried from 2005 to 2014. Women undergoing cholecystectomy during the third trimester of pregnancy (n = 403) were compared with those having this procedure in the 3 months post partum (n = 17,490). Patient demographics as well as maternal delivery and cholecystectomy-related outcomes were compared by standard statistics as well as after adjustments for age, race, comorbidities, insurance status, and hospital setting.

RESULTS

Women who underwent cholecystectomy during the third trimester were older (27 vs 25 years; p < 0.001), but did not differ in race or insurance status. Cholecystectomy during pregnancy was more likely to require hospitalization (85% vs 63%; p < 0.001) and more likely to be performed open (13% vs 2%; p < 0.001). Composite maternal outcomes (odds ratio 1.88; p < 0.001), including preterm delivery (odds ratio 2.05; p < 0.001) as well as length of hospital stay (+0.83 days; p < 0.001) and readmissions (odds ratio 2.05; p = 0.002), were all significantly increased when cholecystectomy was performed during pregnancy.

CONCLUSIONS

Maternal delivery and procedure-related outcomes were worse when cholecystectomy was performed during the third trimester of pregnancy. Preterm delivery, which is associated with multiple adverse infant outcomes, was increased in third-trimester women. Whenever possible, cholecystectomy should be delayed until the postpartum period.

Management of acute abdomen in pregnancy: current perspectives

Acute abdomen in pregnancy represents a unique diagnostic and therapeutic challenge. Acute abdominal pain in pregnancy can occur due to obstetric factors as well for reasons that are unrelated to pregnancy. The diagnostic approach of acute abdomen during pregnancy can be tricky owing to the altered clinical presentations brought about by the anatomical and physiological changes of gestation along with the reluctance to use certain radiological investigations for fear of harming the fetus. Delay in diagnosis and treatment can lead to adverse outcomes for both the mother and fetus. In this article, we attempt to review and discuss the various etiologies, the current concepts of diagnosis, and treatment, with a view to developing a strategy for timely diagnosis and management of pregnant women presenting with acute abdominal pain.

Staplers vs. loop-ligature: a cost analysis from the hospital payer perspective

BACKGROUND

Presently, there is equipoise regarding the surgical technique used to manage the appendiceal stump during laparoscopic appendectomy. The purpose of this research was to determine whether the routine use of loop ligature, compared to stapling, is cost effective from a hospital payer perspective.

METHODS

A retrospective cohort study was conducted amongst patients undergoing emergency laparoscopic surgery for acute appendicitis at two major academic hospitals. In order to eliminate possible systematic bias arising from one technique being preferentially employed with more complex presentations, patients were divided into study groups based on the technique routinely employed by their surgeon, loop ligature (LLA) versus stapler (LSA). Pediatric patients and open appendectomies were excluded. Costs were determined using a previously published model derived from publicly available data from the Ontario Case Costing Initiative, in conjunction with local cost data for disposable procurement. Secondary outcomes included operating room time, length of stay, and complication rates.

RESULTS

Between Jan 1, 2014 and Dec 31, 2015, 567 adult patients had an emergency laparoscopic appendectomy for acute appendicitis. In comparing surgeons who routinely employed LLA to LSA, there was a significant decrease in total mean hospital cost with LLA ($1988 ± $143 vs. $2253 ± $99, p = 0.002). In addition, mean disposable cost was reduced for surgeons using LLA ($310 ± $27 vs. $668 ± $26, p < 0.001). This reduction in cost was not associated with a difference in length of stay (1.5 vs. 1.4 days, p = 0.28) or complication rates (8% vs. 10%, p = 0.43).

CONCLUSIONS

These findings suggest that surgeons who routinely use loop ligature to secure the appendiceal base during emergency laparoscopic appendectomy offer more cost-effective care compared to stapler users, saving their institution more than $200 per case with no clear disadvantages. A shift from routine use of staplers to loop ligature should result in significant overall cost savings to the hospital.

The Association of Coloproctology of Great Britain and Ireland consensus guidelines in surgery for inflammatory bowel disease

AIM

There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology.

METHODS

Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines.

RESULTS

All aspects of surgical care for IBD have been included along with 157 recommendations for management.

CONCLUSION

These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

Laparoscopic Appendectomy in Pregnancy With Acute Appendicitis: Single Center Experience With World Review

OBJECTIVES

This clinical study is aiming to discuss the therapeutic benefit of laparoscopic appendectomy (LA) by comparing with conventional open appendectomy (OA) in pregnancy.

MATERIALS AND METHODS

The clinical data of 26 pregnant women who underwent appendectomy from 2012 to 2016 was retrospectively analyzed. The variables analyzed included baseline information, operation characteristics, maternal complications, and infant health outcomes. The patients were divided in 2 LA and OA groups according to the surgical approach and their clinical characteristics were compared.

RESULTS

Of reported 26 patients, 7 underwent LA whereas the remaining 19 patients underwent OA. The median age of the patients was 28 years (range, 19 to 39 y). The median gestational period was 21.5 weeks (range, 5 to 33 wk). The postoperative pathology showed complicated appendicitis 7 cases. The result showed significantly shorter operation time (42.14±8.63 vs. 65.21±26.58 min, P=0.003), hospital stay (4.14±1.77 vs. 6.47±2.72 d, P=0.021), and earlier recovery of gastrointestinal function in the LA group compared with OA group. There were no maternal and fetal deaths occurred in perioperative period in both groups.

CONCLUSIONS

LA has not increased morbidity and mortality but displayed shorter hospital stay, operation time and recovery of gastrointestinal function to OA as well as good cosmetic results. Therefore, LA in patients with pregnancy can be considered as preferred approach in sophisticated hands without increased risks.

Adnexal Torsion during Pregnancy: Outcomes after Surgical Intervention-A Retrospective Case-Control Study

STUDY OBJECTIVE

To investigate the pregnancy and neonatal outcomes of surgical treatment for adnexal torsion (AT) during pregnancy.

DESIGN

A retrospective case-control study (Canadian Task Force classification II-2).

SETTING

A tertiary care academic medical center.

MEASUREMENTS AND MAIN RESULTS

The study group included all parturients who underwent surgery for suspected AT during pregnancy from January 2005 to January 2017. The control group included parturients with an uneventful pregnancy matched by maternal age, parity, multiple gestation, and pregnancy complications. The primary outcome was gestational age at delivery. Secondary outcomes were perinatal outcomes and intraoperative and immediate postoperative complications. Among 85 study group patients with suspected AT, 78 (91.7%) underwent laparoscopy and 7 (8.3%) laparotomy. Torsion was diagnosed in 84 patients (98.8%). The gestational age at delivery was similar between the study and control groups (38.7 ± 1.5 vs 38.6 ± 1.6 weeks, respectively; p = .908) as was preterm labor (5.8% in both groups, p = 1.00). There was no significant difference between the study and control groups in pregnancy and neonatal outcomes, including Apgar scores, mean cord blood pH (7.25 ± 0.1 and 7.26 ± 0.08, respectively), and birth weight (3040 ± 473 g and 3115 ± 584 g, respectively). In the study group, the mean gestational age at surgery was 11.2 ± 6 weeks (range, 4-34 weeks). The average operative time was 40.2 ± 22 minutes. In the postoperative follow-up, 3 (3.5%) patients had a first trimester miscarriage. A previous cesarean delivery was a risk factor for ovarian torsion during pregnancy (p = .012).

CONCLUSION

Adnexal detorsion with or without additional surgical procedures during pregnancy did not affect the gestational age at delivery and did not appear to increase fetal or maternal complication rates.

Outcomes after open and laparoscopic appendectomy during pregnancy: A meta-analysis

OBJECTIVES

Acute appendicitis is the most prevalent cause of non-obstetrical surgical disease during pregnancy. There is no consensus on the optimal surgical management of acute appendicitis in pregnancy. Our aim is to identify surgical and obstetrical outcomes of laparoscopic (LA) and open approach (OA) in pregnant patients with acute appendicitis.

STUDY DESIGN

Medline, Scopus, Google Scholar, Cochrane CENTRAL Register of Controlled Trials and Clinicaltrials.gov databases were searched for articles published up to May 2017, along with the references of all articles. Prospective and retrospective trials reporting outcomes among pregnant women undergoing laparoscopic and open appendectomy were included. Of the 493 records screened, 20 were eligible for meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Statistical meta-analysis was performed using the RevMan 5.3 software.

RESULTS

A total of 6210 pregnant women from twenty studies were included in meta-analysis. Laparoscopic appendectomy was associated with significantly lower overall complication rates and shorter hospital stays (1835 patients OR 0.48 95% CI 0.29, 0.80 p = 0.005). While the open appendectomy group showed prolongation of gestational age for term deliveries, laparoscopic appendectomy patients had higher rates of fetal loss (543 patients MD -0.46 weeks 95% CI-0.87 to -0.04, p = 0.03 and 4867 patients OR 1.82 95% CI 1.30 to 2.57, p = 0.0006, respectively).

CONCLUSIONS

Current literature remains inconclusive on the optimal approach of appendectomy in pregnant women. Further larger-volume studies are needed in order to elucidate the critical effect of laparoscopic appendectomy on fetal loss rates.

Laparoscopic cystectomy in pregnancy, a viable solution - A 14 years series

STUDY OBJECTIVE

To evaluate the safety and maternal fetal outcome of laparoscopic surgery in the management of ovarian mass in pregnant women and the usage of analgesia in postoperative period.

MATERIALS AND METHODS

This is a retrospective cross-sectional study which was carried out at department of O&G, Putrajaya Hospital. A total of 120 cases of ovarian mass in pregnancy between Jan 2000-December 2014 were evaluated. 115 patients had undergone laparoscopy cystectomy/salpingo-oophorectomy. Women's age, parity, gestational age, surgical technique, operative findings and time, estimated blood loss, postoperative hospital stay, post operative pain score, usage of analgesia, complications of surgery, outcome of the pregnancy and histopathology reports were evaluated.

MEASUREMENT AND MAIN RESULTS

Outcome of the pregnancy and post operative pain score and usage of analgesic were evaluated. The mean gestational week at the time of surgery was 14 weeks 1 day (±2 weeks 1 day). The duration of surgery was 87.4 mins (±34.8 mins) with average blood loss of 110.3 ml (±32.0). Median size of ovarian cyst was 6 cm (IQR 2 cm). 2 cases converted to laparotomy. Only 2 cases were reported with second trimester loss which was diagnosed after 4 weeks and 10 weeks respectively. 5 women received tocolytic agent post operatively, all of them delivered at term.The mean length of hospitalization was 1.51 day (±0.597). The average gestational age of delivery was 37.78 (±3.42) mean birth weight 2.97 kg (±0.65 kg). There was one intrauterine growth restriction baby with birth weight of 1.89 kg at 35 weeks of gestation and another baby with bladder exstrophy with ambiguous genitalia which was not related to surgery. The mean of pain score was 1.5 (±1.6) over 10. 87.9% of the women had mild pain which only 64.6% require paracetamol or no analgesia.

CONCLUSION

Majority of women with ovarian masses in pregnancy can be treated with ensured safety and reduced morbidity using the endoscopic approach.

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.

Estimating the risk of adverse birth outcomes in pregnant women undergoing non-obstetric surgery using routinely collected NHS data: an observational study

Background

Previous research suggests that non-obstetric surgery is carried out in 1–2% of all pregnancies. However, there is limited evidence quantifying the associated risks. Furthermore, of the evidence available, none relates directly to outcomes in the UK, and there are no current NHS guidelines regarding non-obstetric surgery in pregnant women.

Objectives

To estimate the risk of adverse birth outcomes of pregnancies in which non-obstetric surgery was or was not carried out. To further analyse common procedure groups.

Data Source

Hospital Episode Statistics (HES) maternity data collected between 2002–3 and 2011–12.

Main outcomes

Spontaneous abortion, preterm delivery, maternal death, caesarean delivery, long inpatient stay, stillbirth and low birthweight.

Methods

We utilised HES, an administrative database that includes records of all patient admissions and day cases in all English NHS hospitals. We analysed HES maternity data collected between 2002–3 and 2011–12, and identified pregnancies in which non-obstetric surgery was carried out. We used logistic regression models to determine the adjusted relative risk and attributable risk of non-obstetric surgical procedures for adverse birth outcomes and the number needed to harm.

Results

We identified 6,486,280 pregnancies, in 47,628 of which non-obstetric surgery was carried out. In comparison with pregnancies in which surgery was not carried out, we found that non-obstetric surgery was associated with a higher risk of adverse birth outcomes, although the attributable risk was generally low. We estimated that for every 287 pregnancies in which a surgical operation was carried out there was one additional stillbirth; for every 31 operations there was one additional preterm delivery; for every 25 operations there was one additional caesarean section; for every 50 operations there was one additional long inpatient stay; and for every 39 operations there was one additional low-birthweight baby.

Limitations

We have no means of disentangling the effect of the surgery from the effect of the underlying condition itself. Many spontaneous abortions will not be associated with a hospital admission and, therefore, will not be included in our analysis. A spontaneous abortion may be more likely to be reported if it occurs during the same hospital admission as the procedure, and this could account for the associated increased risk with surgery during pregnancy. There are missing values of key data items to determine parity, gestational age, birthweight and stillbirth.

Conclusions

This is the first study to report the risk of adverse birth outcomes following non-obstetric surgery during pregnancy across NHS hospitals in England. We have no means of disentangling the effect of the surgery from the effect of the underlying condition itself. Our observational study can never attribute a causal relationship between surgery and adverse birth outcomes, and we were unable to determine the risk of not undergoing surgery where surgery was clinically indicated. We have some reservations over associations of risk factors with spontaneous abortion because of potential ascertainment bias. However, we believe that our findings and, in particular, the numbers needed to harm improve on previous research, utilise a more recent and larger data set based on UK practices, and are useful reference points for any discussion of risk with prospective patients. The risk of adverse birth outcomes in pregnant women undergoing non-obstetric surgery is relatively low, confirming that surgical procedures during pregnancy are generally safe.

Future work

Further evaluation of the association of non-obstetric surgery and spontaneous abortion. Evaluation of the impact of non-obstetric surgery on the newborn (e.g. neonatal intensive care unit admission, prolonged length of neonatal stay, neonatal death).

Appendectomy in Pregnancy: Appraisal of the Minimally Invasive Approach

BACKGROUND

The optimal surgical approach to acute appendicitis in pregnancy remains controversial. Our aim was to compare perioperative and obstetric outcomes associated with laparoscopic and open appendectomy in a large contemporary cohort of pregnant women.

METHODS

Retrospective review of all women who underwent appendectomy during pregnancy in a single hospital during 2000-2014.

RESULTS

Ninety-two patients met the study criteria. Fifty (54%) underwent laparoscopic appendectomy and 42 (46%) open appendectomy. The laparoscopy group had a lower median gestational age at surgery (16 weeks versus 24 weeks, P < .001), a shorter median hospital stay (5 days versus 3 days, P < .001), and a lower rate of postoperative complications (8% versus 24%, P = .04). There were no significant between-group differences in the rates of gestational age at delivery, Apgar scores, preterm delivery, and fetal loss.

CONCLUSIONS

Laparoscopic appendectomy during pregnancy is safe and associated with better surgical outcomes than open appendectomy, with no difference in obstetric outcomes.

Teratodermoid mimicking cholecystitis

An acute abdomen assessment in pregnancy is complicated. Pain can have obstetric and nonobstetric causes. Cholecystitis is a common cause of pain in pregnancy with significant morbidity if not managed promptly. We report a case of a ruptured, torted, right ovarian teratodermoid erroneously diagnosed as cholecystitis in pregnancy.

Comparison of Laparoscopic Appendectomy with open appendectomy in Treating Children with Appendicitis

Objective:

To analyze feasibility and curative effect of laparoscopic appendectomy in the treatment of pediatric appendicitis and compare it with open appendectomy.

Methods:

Two hundred and sixty patients were selected for this study and randomly divided into open appendectomy group (130 cases) and laparoscopic appendectomy group (130 cases). Patients in open appendectomy group underwent traditional open appendectomy, while patients in laparoscopic appendectomy were treated with laparoscopic appendectomy. Incision length, blood loss during operation, duration of operation, time to leave bed, anus exhausting time, time to take food, catheter drainage time, urinary catheterization time, time of using antibiotics, use of pain killer and incidence of complications such as incision infection, residual abscess and intestinal obstruction were compared between two groups.

Results:

We found relevant indexes including length of incision, amount of bleeding and duration of operation in laparoscopic appendectomy group were better than open appendectomy group after surgery; and differences were statistically significant (P<0.05). Indexes such as time to out of bed, time to take food, exhaust time, drainage time, catheterization time and application time and use of antibiotics in laparoscopic appendectomy group were all superior to open appendectomy group, and differences had statistical significance (P<0.05). Incidence of complications in laparoscopic appendectomy group was much lower than open appendectomy group and the difference was statistically significant (P<0.05).

Conclusion:

Laparoscopic appendectomy has advantages of small trauma, sound curative effect, low incidence of complications and rapid recovery and can effectively relieve pain of children suffering from appendicitis. Hence it is worth promotion and should be preferred.

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.

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.

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.

Laparoscopic surgery performed in advanced pregnancy compared to early pregnancy

PURPOSE

The aim of our study was to assess the clinical and obstetric outcomes of laparoscopic surgeries performed during advanced pregnancy compared to those performed in early pregnancy.

METHODS

We retrospectively reviewed all cases of patients who underwent laparoscopic surgery during pregnancy in our institution between 1996 and 2013.

RESULTS

We reviewed cases of 117 pregnant women who underwent laparoscopic surgery during the study period. There were no conversions to laparotomy. 71 surgeries were performed in the first trimester (group 1, mean gestational age 7.7 ± 1.9 weeks) and 46 were performed in the second and third trimesters (group 2, mean gestational age 18.1 ± 4.3 weeks). More patients in group 1 underwent surgery for suspected adnexal torsion (p < 0.001), while more patients in group 2 underwent surgery for presumptive cholecystitis (p = 0.014) and persistent ovarian mass (p = 0.011). The interval between admission and surgery differed significantly between the groups and was longer in group 2 compared to group 1 (18.2 ± 24.0 vs. 6.8 ± 10.6 h, p = 0.001). No difference was found between the two groups regarding surgical complications, histopathological findings and pregnancy outcomes.

CONCLUSION

In our experience, laparoscopic surgery in advanced pregnancy was found to be feasible and safe as in early pregnancy, without any adverse effects on pregnancy outcome.

Laparoscopic cholecystectomy in pregnancy: An Australian retrospective cohort study

INTRODUCTION

Biliary tract disease is a common non-obstetric surgical presentation during pregnancy. Although small international series demonstrate favourable outcomes following laparoscopic cholecystectomy (LC) during pregnancy, there is a paucity of Australian data to complement these findings.

METHOD

Between 1st January 2003 and 30th June 2013, all patients undergoing planned LC during pregnancy at Western Health were retrospectively identified.

RESULTS

Twenty-two patients underwent planned LC with 3 (13%) cases converted to open surgery. The median maternal age was 31 years (27.8-36) with an estimated median gestational age (EGA) of 19.5 weeks (16.5-23.5). Eighteen (82%) cases were performed during the second trimester. Nine (40%) patients had 2 or more hospital admissions for similar presentations. Twelve (54%) were performed as index cases. Operative indications included 12 (54%) with recurrent biliary colic, five (22%) with acute cholecystitis and 3 (14%) with gallstone pancreatitis. Median operating time for completed LCs was 65 min (60-95). Intra-operative cholangiogram was performed in seven (32%) cases, 5 (71%) of which employed protective uterine lead shielding. There was no fetal loss or uterine injury. Median hospital stay was 3 days (2-7) for completed LCs. Major morbidity occurred in 2 (10%) completed LCs that required a return to theatre. Five (23%) births were lost to follow up. The median time to delivery post-surgery was 13 weeks (11-15). Two (12%) preterm deliveries occurred, with subsequent neonatal complications.

CONCLUSION

Antenatal laparoscopic cholecystectomy demonstrated comparably safe outcomes. Increasing its utilization to manage symptomatic cholelithiasis during pregnancy may be considered.

Advances in understanding and treating liver diseases during pregnancy: A review

Liver disease in pregnancy is rare but pregnancy-related liver diseases may cause threat to fetal and maternal survival. It includes pre-eclampsia; eclampsia; haemolysis, elevated liver enzymes, and low platelets syndrome; acute fatty liver of pregnancy; hyperemesis gravidarum; and intrahepatic cholestasis of pregnancy. Recent basic researches have shown the various etiologies involved in this disease entity. With these advances, rapid diagnosis is essential for severe cases since the decision of immediate delivery is important for maternal and fetal survival. The other therapeutic options have also been shown in recent reports based on the clinical trials and cooperation and information sharing between hepatologist and gynecologist is important for timely therapeutic intervention. Therefore, correct understandings of diseases and differential diagnosis from the pre-existing and co-incidental liver diseases during the pregnancy will help to achieve better prognosis. Therefore, here we review and summarized recent advances in understanding the etiologies, clinical courses and management of liver disease in pregnancy. This information will contribute to physicians for diagnosis of disease and optimum management of patients.
