A Rare Case of Obstructive Jaundice Secondary to Hemobilia Post Endoscopic Ultrasound Guided Liver Biopsy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Hemobilia is an uncommon complication of endoscopic liver biopsy (LB), rarely resulting in clinically significant biliary obstruction. We describe the second reported case of hemobilia‐induced obstructive jaundice secondary to endoscopic ultrasound‐guided LB (EUS‐LB).

Refining Tumor Mutational Burden as a Predictive Biomarker for Pembrolizumab: A Real‐World Analysis in Japanese Patients

Cancer Science, Volume 117, Issue 4, Page 1158-1166, April 2026.
In this study, we investigated the predictive value of tumor mutational burden (TMB) for assessing the efficacy of pembrolizumab in a Japanese cohort. We analyzed real‐world data from 63,952 patients registered in the C‐CAT database who underwent comprehensive genomic profiling, and evaluated the therapeutic efficacy of pembrolizumab in 1899 of these ...

Safety and Feasibility of Laparoscopic and Endoscopic Cooperative Surgery With Endoscopic Submucosal Dissection for Large Superficial Non‐Ampullary Duodenal Epithelial Tumors

Annals of Gastroenterological Surgery, Volume 10, Issue 2, Page 460-469, March 2026.
ABSTRACT Background and Aims Endoscopic submucosal dissection (ESD) for large superficial non‐ampullary duodenal epithelial tumors (SNADETs) poses substantial technical challenges, primarily because of a heightened risk of adverse events (AEs). Laparoscopic and endoscopic cooperative surgery (D‐LECS) was introduced to address these risks, with recent ...

Outcomes of Pancreas‐Sparing Total Duodenectomy for Severe Duodenal Polyposis in Patients With Familial Adenomatous Polyposis

Annals of Gastroenterological Surgery, Volume 10, Issue 2, Page 534-542, March 2026.
ABSTRACT Aim Spigelman stage IV duodenal polyposis (SP‐stage IV DP) is associated with high duodenal cancer risk in patients with familial adenomatous polyposis (FAP). This study evaluated the surgical and oncological outcomes of pancreas‐sparing total duodenectomy (PSTD) as a surgical prophylaxis for severe duodenal polyposis in FAP.

Early‐life body size and risk of developing biliary tract cancers

Cancer, Volume 132, Issue 5, 1 March 2026.
This visual abstract illustrates how childhood body size influences biliary tract cancer (BTC) risk. By using more than 340,000 Danish children’s health records, body mass index trajectories between ages 6 and 15 years were investigated. The results show that obesity during childhood significantly increases BTC risk, with sex‐specific differences ...
