Acute pancreatitis in the postpartum period: a population-based case-control study

Acute Pancreatitis during and after Pregnancy: A Review

During pregnancy and in the post-partum period, several diseases may arise or become exacerbated. Acute pancreatitis is an inflammatory disease with an increasing incidence in Western countries. The incidence of acute pancreatitis during pregnancy is not different with respect to the general population, but this incidence increases in the first 2 years after delivery. Biliary sludge and stones are the most frequent aetiologies, followed by hypertriglyceridemia. Taking care of the mother and foetus through a potentially severe disease requires a team consisting of an obstetrician, a gastroenterologist, an anaesthesiologist, and a surgeon. It is necessary to monitor the health of the foetus/child and the mother during pregnancy, childbirth, and puerperium. The management of this care depends on the systemic and local complications, the severity of the acute pancreatitis, and the trimester of pregnancy. Some diagnostic tools and many drugs are not safe for foetuses, while interventional endoscopy and surgery have limitations and can only be used after an accurate evaluation of benefit/risk ratios. Despite these limitations, maternal mortality due to acute pancreatitis is low during pregnancy, mainly thanks to multidisciplinary approaches for these patients. A careful diet to prevent obesity, alcohol abstinence, routine serum triglyceride control, and breastfeeding for at least three months may prevent acute pancreatitis during and after pregnancy.

Breastfeeding in Prevention of Postpartum Acute Pancreatitis

BACKGROUND

Acute pancreatitis (AP) caused by gallstones has an increased rate of incidence in young women in the 2 years postpartum. Middle-aged women with longer periods of breastfeeding have less hospitalization for gallbladder disease.

AIM

To investigate whether breastfeeding or other variables may be associated with AP.

METHODS

We conducted a population-based case-control study among all Sicilian women of childbearing age, and we identified all women who delivered (2013-2016) and had AP within 2 years postpartum. We reviewed their medical records, and for each case we matched four women of the same age (± 5 years), without AP. Univariate and multivariate logistic regression was used to estimate the odds ratios (OR) with their confidence intervals (CI) to assess associations between AP and clinical determinants.

RESULTS

In the 74 women with AP and 298 controls at univariate analysis, > 6 months oral contraception history (p < 0.01; OR 3.30; 95% CI 1.33-8.16), previous biliary disease (p < 0.001; OR 5.90; 95% CI 1.98-17.57) and smoking (p = 0.035; OR 2.04; 95% CI 1.04-4.0) were predictors of AP; amenorrhea ≥ 3 months (p < 0.001; OR 0.34; 95% CI 0.19-0.59) and breastfeeding ≥ 3 months (p < 0.001; OR 0.07; 95% CI 0.03-0.14) were protective. At multivariate analysis, previous biliary disease (p = 0.011; OR 5.49; 95% CI 1.48-20.38) and breastfeeding ≥ 3 months (p < 0.001; OR 0.06; CI 95% 0.03-0.14) were associated with AP.

CONCLUSIONS

Women who breastfeed for at least 3 months and do not have a history of biliary disorders have reduced risk of developing AP in the 2 years after delivery.

Acute Pancreatitis During and After Pregnancy: Incidence, Risk Factors, and Prognosis

BACKGROUND

Acute pancreatitis may complicate pregnancy and both are associated with gallstones, but its incidence is not well known.

AIMS

To validate hospital discharge records in diagnosing acute pancreatitis and gallstones and to evaluate acute pancreatitis incidence in non pregnant, pregnant and after delivery using hospital discharge records METHODS: We identified all hospital discharge records of hospitalized Sicilian women of childbearing age (2011-2016). We determined agreement between 300 hospital discharge records and hospital records in diagnosing acute pancreatitis and gallstones. Acute pancreatitis incidence, prognosis, and their relationship with age and gallstones were calculated in the three groups using hospital discharge records.

RESULTS

There was 92% and 88% agreement in diagnosing acute pancreatitis and gallstones between hospital discharge and hospital records. In non pregnant, 1,564 of 7,236,863 women-years (21.61/100,000 person-years) developed acute pancreatitis. During pregnancy, 34 of 226,492 women-years developed acute pancreatitis (20.02/100,000 person-years). Postpartum acute pancreatitis incidence was higher than non pregnant, only in the first 2 years with the peak in the first semester (95.4/100,000 person-years). The increased incidence of postpartum acute pancreatitis was associated with gallstones in youngest women (gallstones acute pancreatitis in women below 20 years old versus non pregnant: rate ratios 16.61; 95% CI 8.40-32.87).

CONCLUSIONS

Agreement in acute pancreatitis and gallstones diagnosis between hospital discharge and hospital records was accurate. Acute pancreatitis incidence was increased only in the first 2 years after delivery in young women with gallstones.

A Rare Case of Acute Idiopathic Pancreatitis in Third Trimester Which Aggravated in Early Postpartum Period

Acute pancreatitis (AP) in pregnancy and post-partum period is a rare event and can have a lethal effect on the mother and the fetus. Gallstone disease is thought to be the most common causative factor of AP; however, in many cases the cause remains unclear. Here, we present a case of severe AP occurring in late pregnancy which aggravated in the early postpartum period. A 32-year-old multiparous woman, para 7, presented with severe abdominal pain, abdominal distension and multiple episodes of vomiting. The pain was localized to the upper abdomen and radiating to the back, aggravated by food and bending forward. She had neither a history of chronic alcoholism nor any evidence of viral infection was found. The patient was diagnosed with idiopathic severe AP on contrast-enhanced computed tomography, which was managed conservatively and recovered within several days. She did not have any recurrence thereafter and had a good clinical recovery. Therefore, it is important to consider AP when a woman presents with upper abdominal pain, nausea and vomiting in pregnancy and during the postpartum period to improve the maternal outcome for patients with AP.

Acute pancreatitis in pregnancy

OBJECTIVE

The highest maternal-fetal risk from pancreatitis in pregnancy is likely to be posed by the most severe cases, which we have compared with mild cases.

DESIGN

Retrospective observational study.

SETTING

A general surgery department of a university referral hospital in Nanjing, China.

POPULATION

Eighteen pregnancies complicated with severe acute pancreatitis and 51 pregnancies complicated with mild acute pancreatitis.

METHODS

Medical records were reviewed for every pregnant woman with mild or severe acute pancreatitis during January 1999 to December 2009.

MAIN OUTCOME MEASURES

Information on demographics, clinical and laboratory data, maternal and fetal outcomes.

RESULTS

Gestational age of onset was significantly higher in the severe acute pancreatitis group than in the mild acute pancreatitis group. Severe hypertriglyceridemia was considered the main cause of severe acute pancreatitis (OR 20.7; 95% CI 4.6-92.4, p<0.001), while biliary disease contributed to the etiology of mild acute pancreatitis (OR 7.3; 95% CI 1.8-30.1, p<0.01). Abortions and preterm infants contributed to fetal loss in the mild group, while fetal death and stillbirth contributed in the severe group.

CONCLUSIONS

Hyperlipidemic pancreatitis and biliary pancreatitis are the main causes of severe and mild disease, respectively. Severe acute pancreatitis in pregnancy usually occurs in the third trimester, and the affected severe patients are more liable to develop a critical condition that results in higher risk of intrauterine fetal death.

Acute pancreatitis and pregnancy: a 10-year single center experience

BACKGROUND

Acute pancreatitis in pregnancy is rare. We report our institutional therapeutic approaches to this disease and its effect on maternal and fetal outcomes.

METHODS

A retrospective review of medical records of pregnant women admitted to Brigham and Women's Hospital between 1996 and 2006.

RESULTS

Twenty-one patients, presenting with 34 episodes of acute pancreatitis were identified. Most attacks (56%) occurred in the second trimester. Twelve patients had biliary pancreatitis. Three had pancreatitis secondary to other causes and six had "undetermined" etiologies. Of those with biliary pancreatitis, six underwent cholecystectomy; in a third of these cases, initial conservative therapy had failed. The other six patients underwent endoscopic sphincterotomy (n=2) or conservative therapy (n=4). Fifty percent of the patients with biliary pancreatitis managed conservatively had a recurrent episode of pancreatitis vs none in the cholecystectomy group. There was no significant difference in length of hospital stay between the three treatment groups (cholecystectomy, sphincterotomy, and conservative therapy). No maternal deaths were observed; there were four preterm labors and one fetal loss.

CONCLUSION

If treated conservatively, pregnant patients with biliary pancreatitis appear to have a high recurrence rate. Early surgical intervention is appropriate, safe, and does not increase the length of hospital stay.

Severe acute pancreatitis and pregnancy

For most patients with pregnancy-associated pancreatitis there is little maternal survival threat and only occasionally are there foetal deaths. We describe 4 young women with pregnancy-associated severe acute pancreatitis who each had gallstones. Their ages were 17, 18, 20 and 24 years. Each was a tertiary referral to our unit in Glasgow and each pursued a life-threatening course with hospital stays ranging from 37 to 90 days. One patient required pancreatic necrosectomy for infected necrosis, another had percutaneous management of a pancreatic abscess and 2 had cystogastrostomy as treatment for pancreatic pseudocyst. All underwent early endoscopic sphincterotomy and later cholecystectomy. It is important to be aware that pregnancy-associated acute pancreatitis may be severe, posing a survival threat even in the youngest patients. Gallstones, as we reported almost 20 years ago, are the most common aetiological factor in such patients.

Acute non-traumatic maternal illnesses in pregnancy: imaging approaches

The imaging methods used to obtain diagnostic information for pregnant patients presenting with acute non-traumatic maternal illnesses have been reviewed. Conditions affecting the gastrointestinal tract, urinary tract, uterus, adnexae, central nervous system and chest have been investigated via a variety of imaging methods, which include ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), intravenous pyelography (IVP), angiography and fluoroscopy. The method of choice, application, and safety to the mother and fetus are considered for investigation of each condition.

Preeclampsia as a Cause of Pancreatitis: A Case Report

BACKGROUND

Pancreatitis is an uncommon but well-described entity in pregnancy and labour, with most cases attributable to biliary disease. Preeclampsia is not an established cause of pancreatitis.

CASE

A 29-year-old woman with preeclampsia and adverse features at 33 weeks' gestation developed pancreatitis during her labour induction. Investigations ruled out known etiologies of pancreatitis. The woman was monitored clinically, biochemically, and radiologically, and underwent a Caesarean delivery of a healthy infant. Both the pancreatitis and preeclampsia resolved rapidly postpartum. Given her benign clinical picture, no specific therapeutic intervention was deemed necessary for the pancreatitis, and she was discharged 5 days postpartum.

CONCLUSION

The clinical course and investigations of this woman suggest that preeclampsia should be considered as a cause of pancreatitis.

Acute pancreatitis occurring in the early postpartum period: a case report

We report a case of acute pancreatitis, which occurred after delivery in a woman who had an uneventful course of pregnancy and parturition. A 17-year-old Japanese woman was referred to our department because of nausea and vomiting two hours after delivery, followed by severe abdominal and back pain. On admission, in addition to elevated serum and urine amylase, plain computed tomography demonstrated a swollen pancreas and high density in the peripancreatic lesion with a large amount of ascites, suggesting the presence of an inflammation of the pancreas as well as peripancreatic lesion. Accompanied by subsiding abdominal and back pain, serum amylase concentration gradually decreased and returned to a normal level on the 11th postpartum day. Acute pancreatitis must be kept in mind when evaluating patients presenting with abdominal pain after delivery.
