Robot-assisted distal gastrectomy and local resection for gastric cancer and gastrointestinal stromal tumor.

Gastrointestinal stromal tumors surrounding the esophagogastric junction are often challenging to resect, with no consensus regarding the optimal surgical technique. Here in, we present a case of concurrent gastric cancer in the antrum and gastrointestinal stromal tumors adjacent to the esophagogastric junction. The patient underwent simultaneous distal gastrectomy and local resection assisted by a surgical robot, avoiding the need for total gastrectomy.

Effect of Continuous Box-trainer Training on Laparoscopic Skills of Surgical Residents: A Prospective, Observational Study.

Background/aim: As opportunities for hands-on surgical training during residency have decreased, off-the-job training before surgery is gaining importance. We developed a training program using a box-trainer for surgical residents. This study aimed to verify the effectiveness of the program.

A luciferase reporter assay for ecdysone agonists using HEK293T cells.

Ecdysone agonists are a class of insecticides that activate the ecdysone receptor (EcR) heterodimerized with the ultraspiracle (USP). Here, we report a new luciferase reporter assay for ecdysone agonists. The assay employs mammalian HEK293T cells transiently transfected with the EcR and USP genes of Chilo suppressalis, along with the taiman (Tai) gene of Drosophila melanogaster that encodes a steroid receptor coactivator.

Laparoscopic hepatectomy for hepatic angiomyolipoma with preoperative diagnosis of other malignancy: a report of 2 cases.

Background: Hepatic angiomyolipoma (HAML) is a rare liver tumor, and hepatectomy is the only effective treatment. Due to the difficulty of correct diagnosis of HAML before surgery by image studies, more than 36.6% of reported HAMLs are misdiagnosed as other malignant liver tumors before surgery.
