Article Synopsis
- Tracheal regeneration is difficult due to its complex structure and limited blood flow; this study introduces scaffold-free artificial tracheas created using bio-3D printing.
- The artificial tracheas feature hyaline cartilage on the front, developed from mesenchymal stem cells, and smooth muscle on the back, with both tissues successfully cultured and matured.
- Histological analyses confirmed the proper differentiation of cells, showing that the artificial trachea consists of functional tissues suitable for potential applications in medical regeneration.
Background/aim: Japanese Gastric Cancer Treatment Guidelines do not recommend adjuvant chemotherapy after radical gastrectomy for pathological stage (p) T1N+ or pT2~3N0 gastric cancer. However, some patients experience disease recurrence. This study aimed to identify the risk factors for recurrence in pT1N+ or pT2-3N0 gastric cancer.

Patients And Methods: Patients aged ≥80 years who underwent curative gastrectomy for stage I-III GC between 2013 and 2020 were included. Clinical factors were retrospectively analyzed.
Introduction: Persistent descending mesocolon (PDM) represents a failure of fusion of the descending mesentery, leading to anatomical abnormalities. This study aimed to examine the effects of anatomical features of PDM on laparoscopic surgical outcomes.
Methods: Patient backgrounds, surgical outcomes, anatomical characteristics, and operative findings were retrospectively compared between 186 patients classified into PDM and non-PDM groups who underwent primary resection for left-sided colon and rectal cancer at our hospital from January 2019 to December 2020.
