Doppler-guided hemorrhoidal artery ligation with suture mucopexy compared with LigaSure™-assisted pile excision for the treatment of grade III hemorrhoids: a prospective randomized controlled trial.

Background: Doppler-guided hemorrhoid artery ligation and stapled hemorrhoidopexy have been used in surgical practices to avoid post-hemorrhoidectomy pain. Our study compared Doppler-guided hemorrhoid artery ligation with suture mucopexy (DGHAL-SM) and ligature-assisted pile excision (LAP) for greater than three grades of internal hemorrhoids.

Methods: Eighty patients with greater than 3 grades of internal hemorrhoids were selected (age range: 20-28 years; average age: 23 years) between January and June 2015.

Nasogastric tube placement with video-guided laryngoscope: A manikin simulator study.

Background: This study aimed to investigate video-guided laryngoscopy for nasogastric tube placement.

Methods: This was an observational comparative study performed in a hospital. The participants included volunteers from the medical staff (physicians and nurses) experienced with nasogastric intubation, and non-medical staff (medical students, pharmacists and emergent medical technicians) with knowledge of nasogastric intubation but lacking procedural experience.
