[Choice of hemorrhoidectomy method in chronic hemorrhoid].
Seventy patients with hemorrhoid of stage III-IV underwent surgery. In the study group (n = 21) hemorrhoidectomy was performed with ultrasonic knife. In control group 1 (n = 22) closed hemorrhoidectomy with recovery of anal canal mucosa was performed, in control group 2 (n = 27)--standard open hemorrhoidectomy with electrocoagulation. When ultrasonic knife was used, time of surgery reduced significantly compared with standard closed and opened hemorrhoidectomy--14.7 +/- 3.7, 40.2 +/- 6.5 and 32.5 +/- 5.6 min respectively (p < 0.05). On day 1 after surgery intensive pains were seen more rarely in patients of the study group compared with ones of both control groups (34, 75 and 66% patients respectively). In subsequent days intensive pains were seen also more rarely in study group than in control groups: on day 3 in 15, 40 and 35 patients, respectively, on day 7 in 5, 30 and 20 patients, respectively (p < 0.05). Degree of pain syndrome on day 1 after surgery in the study and control groups was 3.0 +/- 0.4, 7.0 +/- 0.2 and 6.0 +/- 0.3 points, respectively (p < 0.05). Patients of the study group demonstrated low requirement in narcotic and non-narcotic analgesics compared with the other groups. The time of postoperative rehabilitation of patients in the study and control groups was 12.3 +/- 2.4, 18.5 +/- 3.8 and 20.1 +/- 4.4 days, respectively (p < 0.05).
