Reduced-port robotic pancreaticoduodenectomy with optimized surgical field deployment: early results of single-site plus-two ports method.

Background: The adoption of Robotic Pancreaticoduodenectomy (RPD) is increasing globally. Meanwhile, reduced-port RPD (RPRPD) remains uncommon, requiring robot-specific techniques not possible with laparoscopy. We introduce a unique RPRPD technique optimizing surgical field exposure.

Three-Dimensional Bio-Printed Tubular Tissue Using Dermal Fibroblast Cells as a New Tissue-Engineered Vascular Graft for Venous Replacement.

The current study was a preliminary evaluation of the feasibility and biologic features of three-dimensionally bio-printed tissue-engineered (3D bio-printed) vascular grafts comprising dermal fibroblast spheroids for venous replacement in rats and swine. The scaffold-free tubular tissue was made by the 3D bio-printer with normal human dermal fibroblasts. The tubular tissues were implanted into the infrarenal inferior vena cava of 4 male F344-rnu/rnu athymic nude rats and the short-term patency and histologic features were analyzed.

Predicting conversion surgery in patients with locally advanced pancreatic cancer after modified FOLFIRINOX treatment.

Background: /Objective: FOLFIRINOX therapy (FFX) for locally advanced pancreatic cancer (LAPC) is increasingly recognized as a potent neoadjuvant therapy that enables transition to conversion surgery (CS). However, predictors of CS achievement after chemotherapy are controversial. This study aimed to demonstrate the efficacy of CS after modified FFX (mFFX) in patients with LAPC and to identify and score predictors of CS.

Prediction Model with Reveals Number of Days to Develop Liver Cancer from Blood Test.

The development of liver cancer in patients with hepatitis B is a major problem, and several models have been reported to predict the development of liver cancer. However, no predictive model involving human genetic factors has been reported to date. For the items incorporated in the prediction model reported so far, we selected items that were significant in predicting liver carcinogenesis in Japanese patients with hepatitis B and constructed a prediction model of liver carcinogenesis by the Cox proportional hazard model with the addition of () genotypes.

Acute aortic occlusion in a patient with chronic paralysis due to spinal cord injury: a case report.

Patients with spinal cord injury experience changes in the cardiovascular system and a high morbidity associated with peripheral artery disease. We report a case of acute aortic occlusion in a patient with chronic paralysis due to spinal cord injury. A 65-year-old man with chronic paralysis due to spinal cord injury developed mottling of the right extremity.
