The novelty of the system, called Insewing, is that it allows the use of absorbable suture material instead of metallic staples which are currently used and could cause intestinal stiffness and obstruction. http://medicalxpress.com/news/2013-04-spanish-group-patents-automatic-suture.html Cancer Thu, 25 Apr 2013 10:50:52 EST news286105845 Mutations in single genes can cause catastrophic diseases, such as Huntington's Disease or sickle cell anemia.

The rate of therapeutic intervention in this population is very low; therefore, patients with melena and a nondiagnostic upper endoscopy who are stable and without evidence of ongoing bleeding may be able to safely undergo elective colonoscopy. This study is the largest to-date to examine the diagnostic yield of colonoscopy to investigate melena after a nondiagnostic upper endoscopy in patients from a broad geographic distribution and a variety of clinical practice settings. The study appears in the April issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE). http://medicalxpress.com/news/2012-04-diagnostic-yield-colonoscopy-melena-nondiagnostic.html Diseases, Conditions, Syndromes Tue, 17 Apr 2012 16:13:17 EST news253897991 Patients whose symptoms of Clostridium difficile infection (CDI) start outside of the hospital setting have a higher risk of colectomy due to severe infection, according to a large multicenter study funded by the Centers for Disease Control and Prevention (CDC) and published in Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. http://medicalxpress.com/news/2012-04-community-onset-clostridium-difficile-linked-higher.html Surgery Wed, 04 Apr 2012 11:18:52 EST news252757058 (AP) -- Millions of people have endured a colonoscopy, believing the dreaded exam may help keep them from dying of colon cancer.
