A 66-year-old man was diagnosed with inoperable advanced gastric cancer with liver and peritoneal metastases. The patient underwent SOX therapy as primary chemotherapy; subsequently, liver and peritoneal metastases disappeared. However, lung metastasis was detected later, and weekly paclitaxel(PTX)combined with ramucirumab(RAM)chemotherapy was initiated; subsequently, lung metastasis and advanced gastric cancer disappeared.

- The study aimed to compare the ability of deep learning algorithms and experienced physicians to diagnose gangrenous cholecystitis from CT images, assessing the potential for diagnostic aid in urgent cases.
- It analyzed data from 154 patients, training a convolutional neural network (CNN) with a significant number of images and testing its performance against three blinded physicians.
- Results showed that the CNN outperformed the physicians in key metrics like sensitivity and accuracy, suggesting that deep learning models could be effective tools in clinical decision-making for acute cholecystitis.
A 74-year-old man presented to our hospital because of anorexia. Upper gastrointestinal endoscopy revealed type 3 gastric cancer. Further examination disclosed metastasis to the perigastric lymph nodes and to the liver, and a diagnosis of non- resectable advanced gastric cancer(cT4N2H1P0M0)in cStage Ⅳ was made.

Introduction: As the benefits of minimally invasive surgery are recognized, the rate of laparoscopic liver resection (LLR) is rapidly increasing. Liver tissue is fragile compared to tissue of the stomach and colon. In endoscopic and robotic surgery, sufficient tactile sensation is yet to be obtained.
