Surgery for pancreatic tumors during pregnancy: a case report and review of the literature

Gastrointestinal malignancies in pregnancy

Gastrointestinal malignancies, though uncommon in pregnancy, present several unique challenges with regards to diagnosis, staging, and treatment. Imaging the pregnant patient with a suspected or confirmed GI malignancy requires modifications to the radiologic modality of choice and protocol in order to minimize harm to the fetus, ensure accuracy in diagnosis and staging and guide treatment decisions. In this review article, we discuss the imaging approach to the pregnant patient with GI cancer, including safe radiologic modalities and modifications to imaging protocols. We also review the most common GI cancers encountered in pregnancy, including colorectal, pancreatic, gastric, and small bowel tumors, with emphasis to imaging findings, staging, and treatment considerations.

Pancreatic Disorders of Pregnancy

The pancreas is an organ with both exocrine and endocrine functions that has a vital role in both digestion as well as glucose metabolism. Although pancreatic dysfunction and disorders are rare in pregnancy, they are becoming increasingly more common. Recognition of these disorders and understanding how they can affect pregnancy is imperative to allow for proper management. We provide an overview of the most common pancreatic disorders that are seen in pregnancy.

Pancreatic Tumors Complicating Pregnancy: A Concern for Fetomaternal Well Being

INTRODUCTION

Hemoperitoneum resulting from the rupture of pancreatic tumors is a rare condition, especially during pregnancy.

CASE PRESENTATION

We report a case of a 21-year-old gravida 2, para 1, at 25+5 weeks of gestation, who presented to the hospital with severe epigastric pain and decreased fetal movement. Ultrasonography showed intrauterine fetal death, a retroperitoneal mass in the epigastric region, and hemoperitoneum. Computed tomography scan revealed a heterogeneously enhancing pancreatic mass suggestive of pancreatic neoplasm. However, the late diagnosis and the delay in treatment resulted in a deterioration of maternal status with eventual mortality.

CONCLUSION

Diagnostic difficulties occur because of the rarity of the condition and vague clinical presentations. In case of a pregnancy complicated by hemoperitoneum, prompt effort to stop the intraperitoneal bleeding is imperative.

Challenges in the management of adenocarcinoma of ampulla of Vater in pregnancy: A case report and review of literature

INTRODUCTION

Ampullary adenocarcinoma is a rare entity during pregnancy. It accounts for 0.5% of all gastrointestinal malignancies. The best treatment modality for resectable tumors with the best reported outcome is surgical resection in the form of pancreaticoduodenectomy (Whipple procedure). In this case report, we discuss the challenges in the management of ampullary adenocarcinoma in a pregnant patient.

CASE PRESENTATION

We report a case of 22 years old pregnant women who presented with vague abdominal pain and jaundice at the 28th week of gestation. Endoscopic retrograde cholangiopancreatography (ERCP) showed a stricture around the ampulla and distal common bile duct (CBD). The CBD was stented and a biopsy was taken. Histopathology revealed: an invasive adenocarcinoma. The patient was managed by elective pancreaticoduodenectomy after induction of vaginal delivery at the 34th week of gestation.

CONCLUSION

Diagnosing and managing ampullary adenocarcinoma in pregnant patients in their 3rd trimester is challenging. Yet, a delayed viable delivery followed by a definitive surgery in the form of pancreaticoduodenectomy offers the best outcomes for both the mother & fetus in case of early stage disease.

Pancreatic Aetiology for Massive Upper Gastrointestinal Haemorrhage in Pregnancy

We present herein what we believe is the first reported case of massive upper gastrointestinal bleeding in pregnancy due to a pancreatic neuroendocrine tumour causing left sided portal hypertension. A 37-year-old 27-week pregnant female presented with massive haematemesis and melaena requiring transfusion of 10 units of red cell concentrate. Gastric varices were evident at endoscopy. An MRI revealed a large mass infiltrating the pancreatic tail and spleen with massive upper abdominal varix formation secondary to splenic vein invasion. A caesarean section was performed, followed by a radical en bloc partial pancreatectomy and splenectomy with resection of the fundus of the stomach and ligation of gastric and splenic varices. Her postoperative course was uncomplicated. Histology revealed a well differentiated grade 2 neuroendocrine tumour with final staging of T4N0. This case highlights an infrequently encountered cause of massive gastrointestinal bleeding. Diagnosis and management of pancreatic neuroendocrine tumours, due to their rarity and variable clinical presentation, can be challenging particularly in the setting of pregnancy where the wellbeing of a second patient must also be considered. A multidisciplinary approach with input from obstetricians and general surgeons is required when deciding optimum management, while also taking into account the patient's preferences.

Pancreatic neoplasms in pregnancy: diagnosis, complications, and management

BACKGROUND

Neoplasms of the pancreas during pregnancy are rare, with less than 25 cases of benign and malignant tumors reported in the literature.

METHODS

We present three unique cases of pancreatic tumors occurring during pregnancy--one mucinous cystic neoplasm and two adenocarcinomas. We review the literature regarding pancreatic neoplasms during pregnancy and discuss the diagnosis, complications, and management of these tumors.

RESULTS

Magnetic resonance imaging and ultrasound are the imaging modalities of choice in pregnancy. In patients with benign or premalignant tumors, surgical resection may be postponed until the second trimester. In symptomatic patients, or if there is a concern for intrauterine growth restriction, urgent surgical intervention should be performed. With malignant tumors, the benefit of delaying surgery must be balanced with the risk of maternal disease progression. Termination of the pregnancy should be discussed when a malignant tumor is diagnosed during the first trimester. Pancreatic tumors diagnosed during the third trimester may be resected after delivery. If malignant, early delivery of the fetus and subsequent maternal operation can be considered at appropriate fetal maturity.

CONCLUSION

When these tumors occur during pregnancy, they present a diagnostic and treatment dilemma, with variation in treatment based on gestational age and patient preference.

Pancreatic adenocarcinoma in the pregnant patient: a case report and literature review

Pancreatic cancer is the fifth most common cause of cancer-related death in the USA. However, the antepartum diagnosis of pancreatic adenocarcinoma in the pregnant patient is exceedingly rare, with only six cases previously reported in the literature. Optimizing both maternal and fetal health outcomes is particularly challenging when surgical procedures are necessary for staging and/or therapeutic purposes--as these interventions often pose significant risks to both the mother and the developing fetus. In this article, we report a case of pancreatic adenocarcinoma diagnosed during pregnancy and review the literature on the management issues confronted in this unique clinical situation.

Non-functioning, malignant pancreatic neuroendocrine tumour (PNET): a rare entity during pregnancy

INTRODUCTION

Non-functioning pancreatic neuroendocrine tumours (PNET) are extremely rare tumours. To our knowledge, we are the first to report in the literature on two cases of PNET during pregnancy.

PATIENTS

A 32- and a 35-year-old primigravida, both in their second trimester of pregnancy, were referred to our clinic because of a suspicious mass in the pancreas. Both patients had an uneventful medical history and their laboratory test results, including pancreatic hormones, were unremarkable. Both underwent surgical exploration and resection of the pancreatic tumour. One patient with a tumour in the pancreatic tail underwent a distal pancreatectomy and splenectomy, whereas in the other case a pylorus-preserving pancreaticoduodenectomy was performed due to a tumour in the pancreatic head.

RESULTS

One of the patients delivered a healthy infant, which is now at the age of 6 years in excellent health. The other patient is now in her third trimester of pregnancy without any further complications. Histopathological analysis of both tumours showed a strong expression of chromogranin and synaptophysin, thus both were classified as well-differentiated, non-functioning neuroendocrine carcinomas.

CONCLUSIONS

Although PNETs are extremely rare, this entity can be confirmed as another differential diagnosis for suspicious pancreatic mass during pregnancy. In specialized centres, these tumours can be removed without any harmful consequences to the foetus.

Metastatic pancreatic cancer in late pregnancy: a case report and review of the literature

The occurrence of pancreatic carcinoma in a young patient is rare and even more so in pregnancy. In this case report, we discuss the presentation and management of pancreatic adenocarcinoma, with lung and liver metastases, diagnosed in a woman in her third trimester of pregnancy (28 weeks). Ultrasound and magnetic resonance imaging scans were carried out and pancreatic mass biopsy during endoscopic retrograde cholangiopancreatography was performed. Severe preeclampsia and fetal growth restriction occurred. A female infant was delivered by cesarean section at 30 weeks of gestation for worsening of maternal clinical conditions and hepatic and pancreatic tests. The patient died 50 days after delivery. Although pancreatic cancer is a very rare event in pregnancy, it should be suspected when epigastric abdominal pain and laboratory parameters suggestive of biliary tract obstruction occur in pregnancy to ensure, at the least, a better pregnancy outcome.

Gastrointestinal, Pancreatic, and Hepatic Cancer During Pregnancy

Pregnancy affects the clinical presentation, evaluation, treatment, and prognosis of patients with gastrointestinal cancer. Pregnant patients may present with advanced gastrointestinal cancer as a result of delayed diagnosis, in part because of difficulty differentiating signs and symptoms of cancer from signs and symptoms of normal pregnancy. The approach to cancer surgery and chemotherapy must be modified in pregnant patients to minimize fetal and maternal risks. Because of these factors, women who develop gastrointestinal cancers during pregnancy seem to have a poor prognosis. This article focuses on cancers of the colon, stomach, pancreas, and liver that occur during pregnancy.

Pancreatic adenocarcinoma in the pregnant patient: case report and review of the literature

BACKGROUND

In this case report, the authors discuss the presentation and treatment of pancreatic adenocarcinoma in a pregnant woman. Pancreatic adenocarcinoma is extremely rare in the pregnant patient. Only three cases of pancreatic adenocarcinoma diagnosed antepartum have been reported.

METHODS

A case report and a review of the literature are reported.

RESULTS

The authors report a case of pancreatic adenocarcinoma in a pregnant woman at 17 weeks' gestation. Endoscopic retrograde cholangiopancreatography with stent placement and a pancreaticoduodenectomy were performed successfully.

CONCLUSIONS

Pancreatic adenocarcinoma is very rare in the pregnant patient. However, pancreaticoduodenectomy can be performed successfully. To the authors' knowledge, this is the first report of a pregnant woman treated with pancreaticoduodenectomy for pancreatic adenocarcinoma.
