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. The patients were randomly divided into group A (DGHAL-SM) and group B (LAP); each group had 40 patients. RESULTS: With respect to the postoperative cure rate and anal skin tags, group A was inferior to group B, but the postoperative pain assessment and satisfaction were better than group B (P<0.001). CONCLUSIONS: The DGHAL-SM cure rate was high; the postoperative pain was mild; 97.5% of the patients did not return to hospital because of pain. LAP has a higher cure rate than DGHAL-SM, but the postoperative pain and return rate within 6 h was as high as 65%, and the postoperative satisfaction assessment was lower than DGHAL-SM. Therefore, we recommend that DGHAL-SM for outpatient surgery in patients with greater than three grades of internal hemorrhoids.

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. Medical and non-medical hospital staff performed manual, laryngoscope-assisted and video-guided laryngoscope nasogastric intubation both in the presence and in the absence of an endotracheal tube, using a manikin. Nasogastric intubation times were compared between groups and methods. RESULTS: Using the video-guided laryngoscope resulted in a significantly shorter intubation time compared to the other 2 methods, both with and without an endotracheal tube, for the medical and non-medical staff alike (all p < 0.05). For the medical staff, mean nasogastric intubation time was significantly shorter using video-guided laryngoscope without endotracheal intubation, direct laryngoscope with endotracheal intubation and video-guided laryngoscope with endotracheal intubation compared to manual intubation without endotracheal intubation (0.49, 0.63 and 0.72 vs. 5.63, respectively, p ≤ 0.008). For non-medical staff, nasogastric intubation time was significantly shorter using video-guided laryngoscope without endotracheal intubation, direct laryngoscope with endotracheal intubation and video-guided laryngoscope with endotracheal intubation compared to manual intubation without endotracheal intubation (1.67, 1.58 and 0.95 vs. 6.9, respectively, p ≤ 0.002). And mean nasogastric intubation time for video-guided laryngoscope endotracheal intubation was significantly shorter for medical staff than for non-medical staff (0.49 vs. 1.67 min, respectively, p = 0.041). CONCLUSION: Video-guided laryngoscope reduces nasogastric intubation time compared to manual and direct laryngoscope intubation, which promotes a consistent technique when performed by experienced medical and previously untrained non-medical staff.
