摘 要：AIM:To compare hemorrhoidectomy with a bipolar electrothermal device or hemorrhoidectomy using an ultrasonically activated ***:Sixty patients with grade Ⅲ or Ⅳ hemorrhoids were prospectively randomized to undergo closed hemorrhoidectomy assisted by bipolar diathermy(group 1) or hemorrhoidectomy with the ultrasonic scalpel(group 2).Operative data were recorded,and patients were followed at 1,3,and 6 wk to evaluate *** assessors were assigned to obtain postoperative pain scores,oral analgesic requirement and satisfaction ***:Reduced intraoperative blood loss median 0.9 mL(95% CI:0.8-3.7) vs 4.6 mL(95% CI:3.8-7.0),P = 0.001 and a short operating time median 16(95% CI:14.6-18.2) min vs 31(95% CI:28.1-35.3) min,P 0.0001 was observed in group 1 compared with group *** was a trend towards lower postoperative pain scores on day 1 group 1 median 2(95% CI:1.8-3.5) vs group 2 median 3(95% CI:2.6-4.2),P = *** oral analgesic requirement during postoperative 24 h after operation median 1(95% CI:0.4-0.9) tablet vs 1(95% CI:0.9-1.3) tablet,P = 0.006 was observed in group 1 compared with group *** was no difference between the two groups in the degree of patient satisfaction or number of postoperative ***:Bipolar diathermy hemorrhoidectomy is quick and bloodless and,although as painful as closed hemorrhoidectomy with the ultrasonic scalpel,is associated with a reduced analgesic requirement immediately after operation.
