1001. Botulinum toxin injection versus lateral internal sphincterotomy in the treatment of chronic anal fissure: a non-randomized controlled trial.

作者: Adnan Giral.;Kemal Memisoglu.;Yücel Gültekin.;Neşe Imeryüz.;Cem Kalayci.;Nefise B Ulusoy.;Nurdan Tözün.
来源: BMC Gastroenterol. 2004年4卷7页
Although lateral internal sphincterotomy is the gold-standard treatment for chronic anal fissure, intrasphincteric injection of botulinum toxin seems to be a reliable new option. The aim of this non-randomized study is to compare the effect of lateral internal sphincterotomy and botulinum toxin injection treatments on the outcome and reduction of anal sphincter pressures in patients with chronic anal fissure.

In cirrhosis, an insufficient release of nitric oxide contributes to increased hepatic resistance and portal pressure and enhances the postprandial increase in portal pressure. We hypothesized that simvastatin, which enhances Akt-dependent endothelial nitric oxide synthase phosphorylation, may increase hepatic nitric oxide release and decrease hepatic resistance in patients with cirrhosis and portal hypertension.

1004. The development and maintenance of human visceral pain hypersensitivity is dependent on the N-methyl-D-aspartate receptor.

作者: Robert Paul Willert.;Clifford J Woolf.;Anthony Robert Hobson.;Claire Delaney.;David G Thompson.;Qasim Aziz.
来源: Gastroenterology. 2004年126卷3期683-92页
Visceral hypersensitivity is a common feature of functional gastrointestinal disorders. One speculated mechanism is an activity-dependent increase in spinal cord neuronal excitability (central sensitization), which is dependent on activation of the N-methyl-D-aspartate (NMDA) receptor. Our aims were to determine whether the development and maintenance of human visceral hypersensitivity is NMDA receptor mediated.

In the United States, upper gastrointestinal endoscopy is usually performed using intravenous sedation. Sedation increases the rate of both complications and costs of endoscopy. Unsedated esophagogastroduodenoscopy (EGD) using conventional 8-11-mm endoscopes is an alternative to sedated endoscopy but is generally perceived as unacceptable to many American patients. Unsedated EGD using ultrathin 5-6-mm endoscopes is better tolerated. A randomized trial comparing unsedated ultrathin EGD (UT-EGD) with sedated conventional EGD (C-EGD) in a diverse American population is needed.
