AI Article Synopsis
- An 82-year-old man with jaundice underwent treatment for biliary obstruction caused by common bile duct carcinoma using a SMART self-expandable metallic stent.
- After ten months, the initial stent became occluded, requiring the insertion of two additional stents.
- Fourteen months later, complications arose, leading to the discovery of a stent fracture, highlighting the potential risks associated with metallic stent placement.
Article Abstract
We report our second case of fracture of a SMART self-expandable metallic stent (Cordis Endovascular, Warren, NJ) placed to treat biliary obstruction due to an unresectable common bile duct carcinoma. An 82-year-old man presented with jaundice. Computed tomography and ultrasonography on admission demonstrated a mass in the lower common bile duct. The mass was identified as a common bile duct obstruction. A SMART stent was inserted. Ten months after stent insertion, two additional SMART stents were inserted to relieve obstructive jaundice due to occlusion of the first stent. Fourteen months after insertion of the first stent, endoscopic examination revealed stenosis of the duodenum due to invasion of the common bile duct carcinoma, prompting us to perform a gastrojejunostomy 1 month later. Three months after gastrojejunostomy, the patient presented with obstructive jaundice and cholangitis. A fracture of one of the stents was then discovered on plain X-ray films and percutaneous transhepatic cholangiography. Two SMART stents were inserted simultaneously. In conclusion, we report the fracture of a SMART stent placed for common bile duct carcinoma. Fracture should be considered as a possible complication after metallic stent insertion.

Invasive candidiasis, including intra-abdominal candidiasis (IAC), is a common complication after liver transplantation. Antifungal drugs such as echinocandins and fluconazole (FCZ) are frequently used to prevent or treat such fungal infections. The diffusion of these antifungals within abdominal body sites has been rarely reported, in particular, in liver transplant recipients.

Department of General Surgery, Beijing Electric Power Hospital, State Grid Corporation of China, Capital Medical University, Beijing, 100073, China.
Background: Super-elderly patients with choledocholithiasis are considered to be at high risk for undergoing surgery. While laparoscopic transcystic common bile duct exploration (LTCBDE) is regarded as a challenging procedure for super-elderly patients with choledocholithiasis, there have been no reported cases of its use in super-elderly patients over the age of 96.
Case Summary: This case study presents the case of a 96-year-old female patient with acute calculous cholecystitis and choledocholithiasis.

Background: Endoscopic gallbladder-preserving cholecystolithotomy (EGPC) has become an alternative option for treating cholecystolithiasis. However, developing a new method of EGPC in which the gallbladder wall is not damaged remains a challenge. This study introduced a new EGPC method called endoscopic retrograde cholangiopancreatography (ERCP) combined with extracorporeal shock wave lithotripsy (ESWL), which preserves the integrity of the gallbladder wall in the treatment of cholecystolithiasis complicated with choledocholithiasis.
