1. Hemorrhoids: an experimental model in monkeys.
Match Strength: 11.360
PURPOSE: Hemorrhoids are a matter of concern due to a painful outcome. We describe a simple, easy and reliable experimental model to produce hemorrhoids in monkeys. METHODS: 14 monkeys (Cebus apella) were used. After general anesthesia, hemorrhoids were induced by ligation of the inferior hemorrhoidal vein, which is very alike to humans. The vein was located through a perianal incision, dissected and ligated with a 3-0 vicryl. The skin was sutured with a 4-0 catgut thread. Animals were kept in appropriate cages and evaluated daily. RESULTS: Nine days later there were hemorrhoidal piles in the ... Read More »

2. Botulinum toxin vs. topical glyceryl trinitrate ointment for pain control in patients undergoing hemorrhoidectomy: a randomized trial.
Match Strength: 2.989
PURPOSE: The maximum resting pressure in the anal canal is greatly raised after hemorrhoidectomy. This increase is likely to be the cause of postoperative pain, which is still the most troublesome early problem after hemorrhoidectomy. This study was designed to compare, after hemorrhoidectomy, the effects of intrasphincter injection of botulinum toxin vs. application of glyceryl trinitrate ointment in improving wound healing and reducing postoperative pain at rest or during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and ... Read More »
