Multicenter StudyPrognosis of gastric cancer patients with node-negative metastasis following curative resection: outcomes of the survival and recurrence.
The purpose of the present study was to provide valuable prognostic information on lymph node-negative gastric cancer patients following curative resection. ⋯ The prognosis of lymph node-negative gastric cancer patients was better than that of lymph node-positive gastric cancer patients. Male sex, subtotal gastrectomy and nonserosal involvement should be considered to be the favourable predictors of postoperative long-term survival of lymph node-negative gastric cancer patients. Conversely, limited lymphadenectomy, few dissected nodes and serosal involvement should be considered to be risk factors of postoperative recurrence of lymph node-negative gastric cancer patients.

Propofol is an anesthetic agent that is commonly used for conscious sedation. Propofol has advantages as a sedative agent for endoscopic procedures including rapid onset, short half-life and rapid recovery time. However, concerns exist regarding the potential for respiratory depression, hypotension, perforation due to deep sedation and the need for monitoring by an anesthetist. Propofol has been used under endoscopist supervision at the Stanton Territorial Hospital in Yellowknife, Northwest Territories since 1996 (approximately 7000 cases). ⋯ Propofol can be safely administered in a community hospital setting under endoscopist supervision, with no additional support or monitoring.

Practice GuidelinePropofol use for sedation during endoscopy in adults: a Canadian Association of Gastroenterology position statement.
Over the past decade, multiple clinical reports have demonstrated that the use of propofol sedation for gastrointestinal endoscopy by gastroenterologists and trained endoscopy nurses is safe and effective in appropriately selected patients. Proposed benefits of propofol sedation include rapid onset of action, improved patient comfort and rapid clearance, as well as prompt recovery and discharge from the endoscopy unit. ⋯ In Canada, no formal guidelines currently exist. In the present article, the Clinical Affairs Committee of the Canadian Association of Gastroenterology presents a position statement, incorporating updated information on the use of propofol sedation for endoscopy in adult patients.

Does blood urea nitrogen level predict severity and high-risk endoscopic lesions in patients with nonvariceal upper gastrointestinal bleeding?
Nonvariceal upper gastrointestinal bleeding (UGIB) is a serious medical condition requiring prompt resuscitation and early endoscopic therapy in those with high-risk endoscopic lesions (HRLs). There are little or no data correlating sole blood urea nitrogen (BUN) level with the severity of nonvariceal UGIB or the presence of HRLs in the adult population. ⋯ In patients with nonvariceal UGIB, the BUN level at initial presentation is a weak predictor of the severity of UGIB as defined by ICU admission, but is not helpful in identifying patients with a HRL.

Pneumoscrotum is an unusual problem that is very rarely associated with gastrointestinal endoscopy procedures. It has been reported to occur after colonoscopy and polypectomy. The present paper describes the case of an 81-year-old man with benign pneumoscrotum that formed after polypectomy at the site of a previous rectal polyp. The pneumoscrotum was managed with conservative treatment.
