Randomized controlled trial of bipolar diathermy vs ultrasonic scalpel for closed hemorrhoidectomy

AIM:To compare hemorrhoidectomy with a bipolar electrothermal device or hemorrhoidectomy using an ultrasonically activated scalpel.METHODS: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 complications.Independent assessors were assigned to obtain postoperative pain scores,oral analgesic requirement and satisfaction scores.RESULTS: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 2.There 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 = 0.135.Reduced 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 2.There was no difference between the two groups in the degree of patient satisfaction or number of postoperative complications.CONCLUSION: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.

Quality of life in patients with chronic anal fissure after topical treatment with diltiazem

AIM: To assess the physical and mental health of fissure patients before and after topical treatment with diltiazem. METHODS: Consecutive patients were enrolled prospectively into the study. Quality of life was measured with the short-forum 36 health survey (SF-36) before and after 6-wk treatment with diltiazem. Patients scored symptoms of pain, bleeding, and irritation using numeral rating scales at the initial and follow-up visits. Fissure healing was assessed and side effects were noted. RESULTS: Fissures healed in 21 of 30 (70%) patients. There were significant reductions in the scores of pain, bleeding, and irritation after 1 wk of treatment, respectively. Four patients experienced perianal itching and one patient reported headache. When measured at baseline, pain and irritation showed a negative impact on two of the eight subscales on the SF-36, respectively (bodily pain and social functioning for pain; vitality and mental health for irritation). Repeating the SF-36 showed an improvement in bodily pain (P = 0.001). Patients whose fissures healed reported an improvement in bodily pain, health-perception, vitality, and mental health (P < 0.05). CONCLUSION: Successful treatment of chronic anal fissure with topical diltiazem leads to improvement in health-related quality of life.
