Article Synopsis
- Pseudoaneurysms can occur after hepatobiliary and pancreatic surgeries, and catheter interventions are typically the first step in treatment; however, complications from arterial embolization can arise.
- A case study of a 43-year-old male revealed that a dislodged embolization coil caused bile duct stone formation, leading to recurrent cholangitis after previous treatment for a hepatic artery pseudoaneurysm.
- The case highlights the need for clinicians to monitor embolization coil positions in patients and consider coil migration as a potential cause when diagnosing bile duct stones, especially following hepatic artery embolization.
Article Synopsis
- The Dokkyo study aimed to evaluate the C-reactive protein-to-albumin ratio (CAR) as a predictor for S-1 chemotherapy tolerance in pancreatic cancer patients following surgery, building on findings from the Ehime study.
- In a cohort of 172 patients, those who completed S-1 treatment had a significantly lower CAR compared to non-completers, with a CAR cutoff value of 0.05 indicating a higher completion rate.
- The study confirmed that a higher postoperative CAR is a reliable risk marker for adverse events leading to S-1 non-completion after curative surgery for pancreatic cancer patients.
Shorter Drainage Tube to the Pancreatic Stump Reduces Pancreatic Fistula After Distal Pancreatectomy.

Background: We investigated the relationship between the length of a prophylactic closed-suction drainage tube and clinically relevant postoperative pancreatic fistula (CR-POPF) in distal pancreatectomy (DP).
Materials And Methods: The clinical data of 76 patients who underwent DP using a reinforced stapler for the division of the pancreas at Ehime University Hospital between December 2017 and May 2023 were retrospectively analyzed. Laparoscopic DP was performed in 41 patients (53.
Article Synopsis
- - This study looked at how the shape of the reconstructed portal vein/superior mesenteric vein (PV/SMV) affects long-term nutrition after pancreatic surgery (pancreatoduodenectomy) using a technique called computational fluid dynamics (CFD).
- - Twenty-four patients who had the surgery and were tumor-free for over 9 months were analyzed by creating 3D models from their CT scans taken 3-6 months post-surgery.
- - Results showed that patients with higher pressure or turbulence in blood flow were more likely to experience poorer nutritional recovery within 9 months, demonstrating that CFD can help assess the effectiveness of vein reconstructions.
Purpose: Post-transplant biliary stricture (PBS) is a common and important complication following orthotopic liver transplantation (LT). This study clarified the incidence of PBS and identified its risk factors.
Methods: We retrospectively reviewed the medical records of 67 patients who underwent living-donor LT (LDLT) at our institute between June 2010 and July 2022 and analyzed their clinical characteristics, prognosis, and risk factors for PBS.
