Feasibility of laparoscopic and endoscopic cooperative surgery for gastric gastrointestinal stromal tumor with tumor diameter of >5 cm.

Background: Laparoscopic and endoscopic cooperative surgery (LECS) is an effective treatment for gastric gastrointestinal stromal tumors (GISTs). The utility of LECS for gastric GISTs of > 5 cm remains controversial. This study was performed to investigate the feasibility of LECS for gastric GISTs with a tumor diameter of >5 cm.

Transition-Metal-Free Intermolecular Hydrocarbonation of Styrenes Mediated by NaH/1,10-Phenanthroline.

A transition-metal-free intermolecular coupling reaction of halocompounds with styrenes in the presence of NaH and 1,10-phenanthroline was developed. This reaction afforded hydrocarbonated products with complete anti-Markovnikov selectivity. The method allows the use of a wide range of halocompounds, including aryl and alkyl halides, and good functional group tolerance.

Pleomorphic type undifferentiated gastric sarcoma, report of a case.

Reports on pleomorphic type of undifferentiated sarcoma (PUS) originating from the gastrointestinal tract, especially the stomach, are extremely rare. We herein report a case of pleomorphic type undifferentiated gastric sarcoma. The patient was a 67-year-old woman.

Intraoperative holographic image-guided surgery in a transanal approach for rectal cancer.

Purpose: Urethral injury is one of the most important complications in transanal total mesorectal excision (TaTME) in male patients with rectal cancer. The purpose of this study was to investigate holographic image-guided surgery in TaTME.

Methods: Polygon (stereolithography) files were created and exported from SYNAPSE VINCENT, and then uploaded into the Holoeyes MD system (Holoeyes Inc.

Gastric carcinoma with lymphoid stroma derived from hamartomatous inverted polyp with osteoclast-like giant cells: a case report.

Gastric carcinomas with lymphoid stroma (GCLS) are characterized by prominent stromal infiltration of lymphocyte and account for 1-4% of gastric cancers. Although, osteoclast-like giant cells (OGC) have been reported in some GCLS, OGCs in gastric tumors is exceedingly rare. A 60-year-old woman presented to our hospital after the finding of a positive fecal blood test during a routine medical check.
