Effectiveness of hemorrhoidal treatment by rubber band ligation and infrared photocoagulation.
OBJECTIVE
To demonstrate the effectiveness of the treatment of internal hemorrhoids with rubber band ligation (RBL) and infrared photocoagulation (IRC).


METHODS
From march 1996 to december 1999, we prospectively studied 358 patients with a total of 817 hemorrhoid groups and a follow-up period of 36 months. Distribution according to gender and age was: 210 men with a mean age of 46 years and 148 women with a mean age 45.8 years. The mean number of hemorrhoids treated per patients was 2.3. All of them had complete a follow-up protocol at 15, 30, 60 and 180 days and at 12, 24 and 36 months. Rubber band ligation was performed with McGown ligator and suction pump, placing the band at the base of the hemorrhoid. For the infrared coagulation we used a Lumatec coagulation system, applying at least four shoots around each hemorrhoid, with an exposition time ranging between 1 and 1.5 seconds. Treatment was considered effective when patients became asymptomatic (relief of pain, bleeding or anal itching) and the obliteration of hemorrhoids after the treatment was confirmed by anal inspection and anoscopy.


RESULTS
Two hundred ninety five of 358 patients were treated with RBL (82.4%), this treatment being effective in 98% of the patients after 180 days and very good after 36 months. There were 6/295 relapses at 36 months (2%). All minor and major complications were observed within the first 15 days of treatment: rectal tenesmus in 96/295 patients (32.5%), mild anal pain in 115/295 (38.9%), self-limited and mild bleeding after the detachment of the bands in 30/295 (10%), and febricula in one patient. Sixty three of 358 patients were treated with IRC (17.6%). In this group, relapses were observed in 6/63 patients (9.5%) at 36 months, all of them with grade III hemorrhoids that required additional treatment with RBL. All the complications (inherent to the technique) were observed within the first days: mild anal pain in 40/63 patients (63.4%) and mild bleeding in 1/63 (1.6%). The treatment with RBL or IRC depended on the number of hemorrhoids and the hemorrhoidal grade. No significant differences were found regarding the effectiveness between RBL and IRC for the treatment of grade I-II hemorrhoids, while RBL was more effective for grade III and IV hemorrhoids (p < 0.05).


CONCLUSIONS
RBL and IRC should be considered as a good treatment for all grades of hemorrhoids, due to its effectiveness, its cost-benefit and its small short and long-term morbidity.
