Cholecystoduodenal fistula: a complication of inserted self-expandable metallic biliary stents

Navigating Challenges: Managing Upper Gastrointestinal Bleeding From Cholecystoduodenal Fistula in an Elderly Patient

Cholecystoduodenal fistula (CDF) is an uncommon condition characterized by an abnormal connection between the gallbladder and the duodenum, often linked to cholelithiasis. It typically presents with nonspecific symptoms such as abdominal pain and jaundice but can occasionally result in severe upper gastrointestinal (GI) bleeding. This report describes the case of a 94-year-old female who presented with hypovolemic shock and multiple episodes of hematemesis. An upper GI endoscopy confirmed a CDF with active hemorrhage. Due to her comorbidities and poor performance status, an endoscopic approach using hemostatic spray was chosen, resulting in a favorable clinical outcome. The development of CDF is typically a result of chronic gallbladder inflammation and cholecystitis, leading to adhesion and erosion into the duodenum. Diagnosis involves imaging and endoscopic techniques, and management varies based on the patient's condition, encompassing surgical, endoscopic, or conservative approaches. This case highlights the necessity of considering CDF in the differential diagnosis of upper GI bleeding, especially in patients with recurrent cholecystitis, and emphasizes the importance of individualized management strategies. It is notable for the use of a minimally invasive endoscopic technique to manage a high-risk patient, highlighting an alternative to surgical intervention.

Bad Connection: Stent-to-Stent Fistulization After Common Bile Duct and Transjugular Intrahepatic Portosystemic Shunt Stenting

A 29-year-old man with chronic portal venous thrombosis resulting in portal biliopathy required stenting of his common bile duct (CBD) and underwent a transjugular intrahepatic portosystemic shunt (TIPS) procedure to decrease portal pressures. He later presented with abdominal pain in the setting of prolonged CBD stent placement and was found to have air within his TIPS stent with a fistula on endoscopic retrograde cholangiopancreatography between his fully covered CBD stent and bare metal TIPS stent. There was concern that further intervention would lead to an air embolus. We suggest that when multiple stents are indicated, stent selection with close monitoring is critical.

Predictive factors for pancreatitis and cholecystitis in endoscopic covered metal stenting for distal malignant biliary obstruction

BACKGROUND AND AIM

Pancreatitis and cholecystitis are major complications after self-expandable metal stent (SEMS) placement in distal malignant biliary obstruction. We aimed to clarify predictive factors for pancreatitis and cholecystitis after covered SEMS placement.

METHODS

We retrospectively reviewed 74 consecutive patients with distal malignant biliary obstruction who underwent initial endoscopic drainage using covered SEMS. Predictive factors for pancreatitis and cholecystitis were evaluated in the 74 patients described above and in 66 patients who had not undergone cholecystectomy.

RESULTS

The incidences of pancreatitis and cholecystitis were 10.8% (8/74) and 6.1% (4/66), respectively. Univariate analysis revealed that non-pancreatic cancer (P = 0.018) and contrast injection into the pancreatic duct (P = 0.030) were significant predictive factors for pancreatitis. Multivariate analysis revealed that non-pancreatic cancer (odds ratio [OR], 4.21; 95% confidence interval [CI], 1.63-14.18; P = 0.007) and contrast injection into the pancreatic duct (OR, 3.34; 95% CI, 1.33-9.60; P = 0.016) were significant independent predictive factors for pancreatitis. On the other hand, univariate and multivariate analyses revealed that tumor involvement to the orifice of the cystic duct (OCD) was a significant independent predictive factor for cholecystitis (OR, 5.85; 95% CI, 1.91-27.74; P = 0.005).

CONCLUSIONS

Non-pancreatic cancer and contrast injection into the pancreatic duct were predictive factors for pancreatitis, and tumor involvement to the OCD was a positive predictive factor for cholecystitis after endoscopic covered SEMS placement for distal malignant biliary obstruction.
