RESUMEN
PURPOSE: We present a retrospective clinical study concerning the preliminary experience with the circular stapler in the treatment of hemorrhoids. Early results, complications, and long-term follow-up are revisited. METHODS: Fifty-six consecutive patients with second-, third-, and fourth-degree hemorrhoids were included in the study. Data about operation, early postoperative results, and follow-up at one, two, and four weeks were collected. Patients were also contacted by phone after a long-term follow-up (mean, 33 (range, 5-120) months). RESULTS: Every operation attempted was successfully terminated. The length of the operation was less than 15 minutes. No major bleeding or anastomotic disruption occurred. Six patients (13 percent) who underwent spinal or epidural anesthesia had urinary retention. One patient (1.7 percent) had minor bleeding, and four patients (7.1 percent) experienced transient edema of the anastomotic ring after the operation. None needed further treatments. The mean analgesic requirement was 1.4 (range, zero to eight) ketorolac 30-mg injections; 23 patients (41 percent) received no analgesics, and seven patients (12 percent) required a single extra dose of opiates (10 mg morphine cloridrate). Length of hospital stay was between 0 and 11 (mean, 2.7) days, but 20 patients (35 percent) received an additional operation for coexisting surgical disease. At one week, almost all patients experienced little pain at digital inspection and little bleeding after defecations. No anastomotic leakage, wound infection, or healing delay was found. Three patients (5.3 percent) experienced wound edema and pain during defecation. Two weeks later, one patient (1.7 percent) suffered from painful defecation and ten patients (17 percent) reported minor bleeding, but all returned to normal activities. No pain during defecation, bleeding, stenosis, soiling, incontinence, or other anal symptoms were found at one month after the operation, and all patients were well. All patients were contacted by phone 5 to 120 (mean, 33) months later, and all were pleased with the results of this procedure. There were no symptomatic recurrences. DISCUSSION: Our study confirms the feasibility of circular stapler hemorrhoidectomy in the treatment of hemorrhoids. Complications and postoperative pain were minimal. There were no recurrences during long-term follow-up. CONCLUSION: Mechanical hemorrhoidectomy is a promising new option in the treatment of all patients eligible for a surgical approach.
