Single‐Cell Transcriptomic Analysis of Tumor Heterogeneity and the Microenvironment in Pseudomyxoma Peritonei

Advanced Science, EarlyView.
This study presents a single‐cell atlas of pseudomyxoma peritonei spanning primary and paired metastatic lesions. Distinct epithelial substates, stromal remodeling, immune exclusion, lipid metabolic reprogramming, and a candidate angiogenic network were identified in metastatic lesions.

Artificial Intelligence–Based Surgical Phase Analysis Enables Objective Assessment of Surgeon Skill in Robotic Distal Gastrectomy: A Multicenter Study

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Aim Artificial intelligence (AI)–based surgical video analysis can automate time‐consuming manual assessments and enable objective characterization of surgical workflows. We aimed to construct a large, multicenter, fully annotated dataset of robotic distal gastrectomy (RDG) videos and evaluate the feasibility and performance of an AI model for

Radical Resection of the Third Portion of the Duodenum for Secondary Aortoduodenal Fistula

Annals of Gastroenterological Surgery, EarlyView.
Secondary aortoduodenal fistula most commonly involves the third portion of the duodenum and requires definitive management of both vascular and gastrointestinal components. We demonstrate a step‐by‐step technique for radical duodenal resection and reconstruction performed in structured collaboration with cardiovascular surgeons.

Routing immunomodulatory cytokine-encoded mRNAs to the omentum: turning an enemy into an ally in peritoneal metastasis

OncoImmunology
Peritoneal metastases remain a significant clinical challenge owing to the immunosuppressive nature of the omentum, which serves as a protective niche for disseminated tumor cells.

Refining OVCAR‐3 xenograft models of peritoneal carcinomatosis in nu/nu mice: Comparative intraperitoneal implantation strategies and the role of basement membrane matrix

Animal Models and Experimental Medicine, EarlyView.
A refined murine model of advanced ovarian cancer was established by comparing localized preperitoneal implantation and intraperitoneal injection of OVCAR‐3Luc cells. While localized implantation showed limited tumor persistence, intraperitoneal delivery with BME produced sustained diffuse dissemination confirmed by BLI and histology, providing a ...
