Many surgical procedures are available to treat the disease. The aim of this study was to compare the operative time and outcomes, (post-operative pain and complications) of LigaSure hemorrhoidectomy with those of the open conventional method.
Methods : This randomized single-blind clinical trial included 57 patients (28 in LigaSure and 29 in the open group). The primary variable was the operative time for the excision of a single hemorrhoidal packet. The other variables were post-operative pain measured by morphine doses administered to control pain, scores of visual analogue scale (VAS) used to measure pain severity, pain during home stay measured by doses of oral ibuprofen and the mean daily VAS scores, early complications including bleeding and urinary retention, longer-term complications and time to return to work.
Results : The demographic data were comparatively the same between the two groups. The average time to excise a single packet of hemorrhoid was significantly shorter in the LigaSure group (8.91 min vs. 17.35 min, P<0.001). Post-operative pain measurements (morphine doses and VAS scores) were lower in the LigaSure group, but the differences were not statistically significant (P=0.055 and 0.077, respectively). Complications of the two procedures were also comparable. Neither of the groups returned to work in a shorter time.
Conclusion: LigaSure hemorrhoidectomy seems to be a safe method and it can reduce the operative time significantly. It may also have a modest effect on post-operative pain.

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Oral metronidazole has been previously demonstrated to decrease postoperative pain after open hemorrhoidectomy. The aim of this study was to evaluate the effect of topical metronidazole in reducing postoperative pain of hemorrhoidectomy.
Methods : In this double-blind, clinical trial forty 20- to 40-year old male patients were scheduled for hemorrhoidectomy under spinal anesthesia at the Imam Khomeini Hospital in Urmia, Iran from April to September 2010. The participants were assigned to receive topical metronidazole (n=20) or placebo (n=20). Pain intensity was assessed using a visual analog scale (VAS), the time of first narcotic request and morphine administrations were also recorded.
Results : The VAS scores were lower in metronidazole than the control group but this difference was not statistically significant, except after 24 hr post-surgically. Morphine administration in the first 24 hr was lower in the metronidazole group (P<0.05).
Conclusion: Although metronidazole could not prolong the time of first analgesic request, but application of metronidazole gel is associated with lower analgesic requirement.
