Upper gastrointestinal bleeding: A rare complication of acute cholecystitis

An unusual case of acute cholecystitis complicated by haemobilia and Mirizzi-like obstruction: a case report and review of literature

Introduction

Cystic artery pseudoaneurysm rupture presents a rare yet potentially fatal aetiology for upper gastrointestinal (GI) bleed. While uncommon, its incidence has been rising with increased hepatobiliary surgical interventions, predominantly attributed to iatrogenic injury and rarely secondary to acute cholecystitis. Clinical manifestations typically include epigastric pain, upper GI haemorrhage, and obstructive jaundice. Due to its rarity, it is often excluded from initial differential diagnoses.

Case report

This is an unusual case of a 54-year-old male who presented with acute cholecystitis complicated by haemobilia and Mirizzi-like obstruction, in the setting of cystic artery pseudoaneurysm rupture. Initially, urgent transcatheter angiographic embolization of the cystic artery was performed to achieve hemodynamic stability. However, a triphasic computed tomography (CT) scan revealed the first attempt was unsuccessful, necessitating a second embolization. Subsequent imaging confirmed satisfactory embolization; however, a small area of liver necrosis was observed adjacent to the gallbladder. The patient was stable at discharge from the hospital and had an uncomplicated interval cholecystectomy.

Discussion

This case highlights the complexity and challenges associated with diagnosing and managing cystic artery pseudoaneurysm rupture. Diagnosis often relies on arterial phase contrast-enhanced CT scan. While no guideline currently exist, management typically involves achieving hemodynamic stability through Transcatheter angiographic embolization, followed by interval cholecystectomy.

Conclusion

Early recognition and intervention are crucial in managing cystic artery pseudoaneurysm rupture to prevent life-threatening haemorrhagic shock. Clinicians need to consider this rare condition in patients with upper GI bleeding and abnormal liver function tests.

Laparoscopic cholecystectomy after transcatheter arterial embolisation for haemobilia due to a pseudoaneurysm in the gallbladder: A case report

Pseudoaneurysms of the cystic artery are a rare but significant complication of acute cholecystitis. Laparoscopic cholecystectomy may be a safe alternative to open cholecystectomy in such cases. We report the case of a female patient in her seventies, who presented with anaemia, jaundice, and hepatic dysfunction during hospitalisation for right knee pyogenic arthritis. The patient had no pain in the right upper quadrant. Her serum haemoglobin level was 6.5 g/dL, and upper gastrointestinal endoscopy revealed no abnormalities. Six days later, jaundice worsened, and endoscopic retrograde cholangiopancreatography revealed bloody bile. An endoscopic biliary drainage tube was inserted at the discretion of the gastroenterology department. Contrast-enhanced computed tomography revealed a haematoma in the gallbladder and a pseudoaneurysm in the lateral wall of the gallbladder. On the same day, the endoscopic biliary drainage tube was replaced with an endoscopic nasobiliary drainage tube, which indicated the degree of haemorrhage and enabled lavage of the lumen in cases of obstruction. The next day, angiography revealed a pseudoaneurysm of the deep branch of the cystic artery and coil embolisation was performed at the periphery of the cystic artery. Uninterrupted laparoscopic cholecystectomy was performed. Although laparoscopic cholecystectomy is difficult when bleeding is uncontrolled, it was safely performed following haemostasis using transcatheter arterial embolisation. Laparoscopic cholecystectomy is feasible in haemodynamically stable patients with cystic artery pseudoaneurysms after transcatheter arterial embolisation.

Haemorrhagic cholecystitis: a rare entity not to be forgotten

Haemorrhagic cholecystitis is a rare entity of acute cholecystitis that carries a high morbidity and mortality rate if management is delayed. Its clinical course can mirror that of acute cholecystitis. Characteristic findings on ultrasound or CT scan are useful clues to early diagnosis. Urgent cholecystectomy is required prior to progressing to perforation of gallbladder. Most of the literature are case reports with causes associated with anticoagulation. Herein, we described a morbidly obese patient with poorly controlled diabetes presenting with non-specific right upper quadrant pain and was subsequently diagnosed with haemorrhagic cholecystitis. A review of the literature was also performed to summarise the potential clinical presentations, distinctive imaging findings and management options available for this rare condition.

Acute hemobilia from a pseudoaneurysm of the cystic artery arising from the left hepatic artery: Case report and literature review

INTRODUCTION

Hemobilia represents only 6% of all causes of upper gastrointestinal bleeding.

PRESENTATION OF CASE

We report a rare case of a bleeding pseudoaneurysm of the cystic artery, due to a re-activation of a chronic cholecystitis, which arose with a mixed symptomatology: jaundices and hematemesis.

DISCUSSION

The rarity of our patient is increased for some vascular anatomic variations detected by Computed Tomography that influenced the management of the disease. Our patient was treated by endovascular embolization of the pseudoaneurysm and subsequent cholecystectomy.

CONCLUSION

About pseudoaneurysm of the cystic artery only few cases have been already reported and to date there are no guidelines for its management. We describe both diagnostic features and therapeutic strategies in comparison to the most recent literature.

Haemorrhagic cholecystitis: an unusual cause of upper gastrointestinal bleeding

Haemorrhagic cholecystitis is a rare cause of upper gastrointestinal bleeding and is a difficult diagnosis to make. This case report describes an orthopaedic patient, who developed deranged liver function tests and anaemia after a hemiarthroplasty of the hip. The patient had upper abdominal pain and black stools which clinically appeared to be melaena. An ultrasound scan of the abdomen was inconclusive, and therefore a CT was performed and the potential diagnosis of haemorrhagic cholecystitis was raised. An endoscopic evaluation of the upper gastrointestinal tract showed no evidence of other causes of upper gastrointestinal bleeding. Following an emergency laparotomy and cholecystectomy, she recovered well. This report aims to increase awareness about the uncommon condition of haemorrhagic cholecystitis, and to educate regarding clinical and radiological signs which lead to this diagnosis.
