Laparoscopic cholecystectomy in the third trimester of pregnancy: report of 3 cases

Successful laparoscopic cholecystectomy at 32 weeks of pregnancy - A case report

INTRODUCTION AND IMPORTANCE

During gestation, laparoscopic procedures, if needed, are generally considered most ideal within the second trimester. There are less reports of successful laparoscopic procedures in the third trimester of pregnancy due to performance hesitancy with concerns of preterm labor and/or other complications. While it is rare for laparoscopic cholecystectomy to be performed within the third trimester, it should not be delayed if needed, and excellent outcomes can be achieved with proper port placement and procedure.

CASE PRESENTATION

We present the case of a 22-year-old female thirty-two weeks and six days into gestation who underwent a laparoscopic cholecystectomy with intraoperative cholangiogram after presenting with acute-on-chronic cholecystitis. The procedure was without complications, and both the patient and fetus remained stable following surgery, and were discharged on postoperative day 2.

CLINICAL DISCUSSION

The long-established belief is laparoscopic procedures should ideally be attempted in the second trimester to decrease the risk of preterm labor or spontaneous abortion in obstetric patients. Per SAGES guidelines, when clearly indicated, laparoscopic cholecystectomy should not be avoided in any trimester.

CONCLUSION

This case highlights the relative safety of a laparoscopic cholecystectomy in the third trimester of pregnancy with emphasis on standard technique and proper port placement based on uterus size.

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.

Maternal Exposure of Rats to Isoflurane during Late Pregnancy Impairs Spatial Learning and Memory in the Offspring by Up-Regulating the Expression of Histone Deacetylase 2

Increasing evidence indicates that most general anesthetics can harm developing neurons and induce cognitive dysfunction in a dose- and time-dependent manner. Histone deacetylase 2 (HDAC2) has been implicated in synaptic plasticity and learning and memory. Our previous results showed that maternal exposure to general anesthetics during late pregnancy impaired the offspring's learning and memory, but the role of HDAC2 in it is not known yet. In the present study, pregnant rats were exposed to 1.5% isoflurane in 100% oxygen for 2, 4 or 8 hours or to 100% oxygen only for 8 hours on gestation day 18 (E18). The offspring born to each rat were randomly subdivided into 2 subgroups. Thirty days after birth, the Morris water maze (MWM) was used to assess learning and memory in the offspring. Two hours before each MWM trial, an HDAC inhibitor (SAHA) was given to the offspring in one subgroup, whereas a control solvent was given to those in the other subgroup. The results showed that maternal exposure to isoflurane impaired learning and memory of the offspring, impaired the structure of the hippocampus, increased HDAC2 mRNA and downregulated cyclic adenosine monophosphate (cAMP) response element binding protein (CREB) mRNA, N-methyl-D-aspartate receptor 2 subunit B (NR2B) mRNA and NR2B protein in the hippocampus. These changes were proportional to the duration of the maternal exposure to isoflurane and were reversed by SAHA. These results suggest that exposure to isoflurane during late pregnancy can damage the learning and memory of the offspring rats via the HDAC2-CREB -NR2B pathway. This effect can be reversed by HDAC2 inhibition.

Propofol exposure during late stages of pregnancy impairs learning and memory in rat offspring via the BDNF-TrkB signalling pathway

The brain‐derived neurotrophic factor (BDNF)‐tyrosine kinase B (TrkB) (BDNF‐TrkB) signalling pathway plays a crucial role in regulating learning and memory. Synaptophysin provides the structural basis for synaptic plasticity and depends on BDNF processing and subsequent TrkB signalling. Our previous studies demonstrated that maternal exposure to propofol during late stages of pregnancy impaired learning and memory in rat offspring. The purpose of this study is to investigate whether the BDNF‐TrkB signalling pathway is involved in propofol‐induced learning and memory impairments. Propofol was intravenously infused into pregnant rats for 4 hrs on gestational day 18 (E18). Thirty days after birth, learning and memory of offspring was assessed by the Morris water maze (MWM) test. After the MWM test, BDNF and TrkB transcript and protein levels were measured in rat offspring hippocampus tissues using real‐time PCR (RT‐PCR) and immunohistochemistry (IHC), respectively. The levels of phosphorylated‐TrkB (phospho‐TrkB) and synaptophysin were measured by western blot. It was discovered that maternal exposure to propofol on day E18 impaired spatial learning and memory of rat offspring, decreased mRNA and protein levels of BDNF and TrkB, and decreased the levels of both phospho‐TrkB and synaptophysin in the hippocampus. Furthermore, the TrkB agonist 7,8‐dihydroxyflavone (7,8‐DHF) reversed all of the observed changes. Treatment with 7,8‐DHF had no significant effects on the offspring that were not exposed to propofol. The results herein indicate that maternal exposure to propofol during the late stages of pregnancy impairs spatial learning and memory of offspring by disturbing the BDNF‐TrkB signalling pathway. The TrkB agonist 7,8‐DHF might be a potential therapy for learning and memory impairments induced by maternal propofol exposure.

Surgery for gallstone disease during pregnancy does not increase fetal or maternal mortality: a meta-analysis

BACKGROUND

Pregnancy was traditionally considered a contraindication to cholecystectomy but is now becoming the favoured option for gallstone-related disease (GRD) during pregnancy.

METHODS

To assess if cholecystectomy during pregnancy increases the risk of preterm labour, fetal mortality and maternal mortality. PubMed and MEDLINE databases for the period from January 1966 through December 2013. Studies were both conservative and surgical intervention was utilised in the management of GRD were included. The results of the included studies were pooled using meta-analysis techniques.

RESULTS

Surgical intervention for GRD in pregnancy does not increase the risk of preterm labour, fetal mortality or maternal mortality.

CONCLUSIONS

Cholecystectomy during pregnancy for GRD is associated with low complications for the fetus and mother and should be considered in all suitable patients.

[Anaesthetic management of patients in the third trimester of pregnancy undergoing urgent laparoscopic surgery. Experience in a general hospital]

BACKGROUND

Laparoscopic surgery is well accepted as a safe technique when performed on a third trimester pregnant woman.

OBJECTIVE

The aim is to describe the anaesthetic management of a group of patients undergoing this type of surgery.

MATERIAL AND METHODS

An analysis was made of records of 6 patients in their third trimester of pregnancy and who underwent urgent laparoscopic surgery from 2011 to 2013.

CLINICAL CASES

The study included 6 patients, with a diagnosis of acute cholecystitis in 4 of them. The other 2 patients had acute appendicitis, both of who presented threatened preterm labour.

CONCLUSION

The most frequent indications for laparoscopic surgery during the last trimester of birth were found to be acute cholecystitis and acute appendicitis. Acute appendicitis is related to an elevated risk of presenting threatened preterm labour.

[Acute pancreatitis and pregnancy: Cases study and literature review]

OBJECTIVE

To describe issues associated with the diagnosis of acute pregnancy-associated pancreatitis.

MATERIALS AND METHODS

Retrospective study of cases presenting at our establishment from 2002 to 2012. These cases were defined on the basis of the association of abdominal pain, serum lipase levels three times normal values, or signs of pancreatitis on ultrasound scans carried out on women pregnant at the time of diagnosis. A retrospective analysis of the medical files of these patients was carried out, considering epidemiological and etiological criteria, the treatments administered and maternal/fetal fate.

RESULTS

We identified 10 cases during the study period, corresponding to an incidence of 1/1942. In 70% of cases, the patient was in the last three months of pregnancy. The pain was atypical in 70% of cases and ultrasound revealed biliary lithiasis in 30% of cases. None of the women died. In terms of neonatal morbidity, there were five preterm births, including one of an infant that died at the age of seven days. We then carried out a literature review, from which we determined the most appropriate course of action in cases of acute pancreatitis during pregnancy.

CONCLUSION

Pancreatitis should be considered in pregnant women with abdominal pains because this diagnosis is easy to confirm and maternal and fetal outcomes are essentially dependent on the early etiological management of this condition. Preterm birth is the predominant factor for neonatal morbidity.

Conservative management of cholelithiasis and its complications in pregnancy is associated with recurrent symptoms and more emergency department visits

BACKGROUND

Pancreaticobiliary complications of gallstones are common in pregnancy and can result in serious sequelae. Previous studies have shown conflicting results regarding different approaches of treatment.

OBJECTIVE

To compare the outcomes of conservative treatment versus operative and endoscopic interventions in the management of complications related to gallstones during pregnancy.

DESIGN

Retrospective chart review.

SETTING

Tertiary-care referral facility.

PATIENTS

A total of 112 patients who had complications related to gallstones during pregnancy.

INTERVENTION

Patients were classified into 3 groups: conservative treatment, laparoscopic cholecystectomy (LC), and ERCP.

MAIN OUTCOME MEASUREMENTS

We collected demographic data and information regarding treatment complications and pregnancy outcomes.

RESULTS

A total of 112 pregnant patients met the inclusion criteria, with a mean age of 25 years. Main clinical presentations were biliary colic (n = 56), biliary pancreatitis (n = 27), acute cholecystitis (n = 17), and choledocholithiasis (n = 12). A total of 68 patients underwent conservative treatment, 13 patients underwent ERCP, 27 patients had LC, and 4 patients received both ERCP and LC. Recurrent biliary symptoms were significantly more common in patients who received conservative treatment (P = .0005). The number of emergency department visits was significantly higher in the conservative treatment group compared with the active intervention group (P = .0006). The number of hospitalizations also was higher in the conservative treatment group (P = .03). Fetal birth weight was similar in both groups (P = .1). Patients treated conservatively were more likely to undergo cesarean section operations for childbirth (P = .04).

LIMITATIONS

Single-center, retrospective study.

CONCLUSION

Conservative treatment of cholelithiasis and its complications during pregnancy is associated with recurrent biliary symptoms and frequent emergency department visits. ERCP and LC are safe alternative approaches during pregnancy.

Maternal postoperative complications after nonobstetric antenatal surgery

OBJECTIVE

Our primary objective is to estimate the occurrence of major maternal 30 day postoperative complications after nonobstetric antenatal surgery.

METHODS

We analyzed the 2005-2009 data files from the American College of Surgeons National Surgical Quality Improvement Program to assess outcomes for pregnant women undergoing nonobstetric antenatal surgery during any trimester of pregnancy as classified by CPT-4 codes. t Tests, χ(2), logistic regression and other tests were used to calculate composite 30-day major postoperative complications and associations of preoperative predictors with 30 day postoperative morbidity.

RESULTS

The most common nonobstetric antenatal surgical procedure among the 1969 included women was appendectomy (44.0%). The prevalence of composite 30-day major postoperative complications was 5.8% (n = 115). This included (not exclusive categories): return to the surgical operating room within 30 days of surgery 3.6%, infectious morbidity 2.0%, wound morbidity 1.4%, 30 day respiratory morbidity 2.0%, venous thromboembolic event morbidity 0.5%, postoperative blood transfusion 0.2%, and maternal mortality 0.25%.

CONCLUSION

Major maternal postoperative complications following nonobstetric antenatal surgery were low (5.8%). Maternal postoperative mortality was rare (0.25%).
