Abstract

Background/Aims: Elastic band ligation is a well-established method for the treatment of internal hemorrhoids. The aim of this study was to assess the treatment outcomes of flexible endoscopic rubber band ligation of internal hemorrhoids. Methods: Using a flexible endoscope, 30 patients with symptomatic internal hemorrhoids were evaluated based on change in clinical symptoms (Goligher grade, bleeding score) and endoscopic classifications (range, size) before and after the procedure. Results: Goligher grade and bleeding score showed significant improvement after the procedure (Goligher grade from 2.12 to 0.54, p<0.01, and bleeding score from 1.80 to 0.40, p<0.01). Endoscopic classification scores improved significantly after the procedure (range 3.03 to 1.55, p<0.01, and size from 1.80 to 0.85, p<0.01). As a complication, mild pain developed in 19 patients (90.5%) and severe pain in two patients (9.5%). Most (90.5%) were well controlled by conservative management, but one patient was operated on for hemorrhoidal thrombosis and in another patient the ligated rubber band had to be released promptly for pain relief. One patient (3.3%) experienced mild infection, which was relieved by medical treatment. During the 16.7${\pm}$3.2-month period of follow-up, two patients relapsed, one was treated with additional endoscopic band ligation, and one underwent surgery. Conclusions: Flexible endoscopic band ligation is an effective and safe method of treatment in patients with symptomatic internal hemorrhoids.

목적: 내시경적 고무 밴드 결찰술은 증세가 있는 내치핵 환자에서 각광받고 있는 비침습적인 시술로 알려져 있다. 본 연구는 EBL의 효과 및 안정성에 대해서 알아 보고자 하였다. 방법: 굴곡성 위장관 내시경을 이용하여 증세가 있는 내치핵 환자 30명을 대상으로 시술을 시행하였다. 환자들의 Goligher 등급체계와 대변과의 연관성에 따른 출혈 점수를 이용하여 임상적 소견을 분류하였고, 치핵 내강의 범위와 크기를 이용하여 내시경적 소견을 분류하였다. EBL 시행 전후로 임상적 소견과 내시경적 소견을 비교하여 유의성을 알아보고자 하였다. 결과: 대상 환자 30명의 남녀 비는 13:17이었고, 평균 연령은 56.2${\pm}$13.6세였다. 증상은 항문 출혈이 24예(80.0%), 점막 돌출 20예(66.7%)로 가장 흔하였다. Goligher 등급은 시술 전 2.12점에서 시술 후 0.54점으로 유의하게 감소하였고(p<0.01), 출혈점수는 시술 전 1.80점에서 시술 후 0.40점으로 유의하게 감소하였다(p<0.01). 내치질의 범위에 따른 점수 체계는 시술 전 3.03점에서 시술 후 1.55점으로 유의하게 감소하였고(p<0.01), 치질의 크기는 시술 전 1.80점에서 시술 후 0.85점으로 유의하게 감소하였다(p<0.01). 적색 징후는 치료전 19예(63.3%)에서 관찰되었으나 치료 후 15예(89.5%)에서 소실되었다. 추적관찰 기간 중 재발은 총 2예(6.7%)에서 발생하였고, 그 중 1예(3.3%)에서는 EBL을 추가적으로 시행하여 경과관찰 중이고, 1예(3.3%)에서는 수술적 치료를 받았다. 시술과 관련된 합병증으로 통증이 총 21예(70.0%)로 가장 흔하였다. 대부분은(19예, 90.5%) 경도 통증으로 2~3일간의 진통소염제로 증세가 소실되었고, 2예(9.5%)에서는 중등도 이상의 통증이 관찰되어 1예(4.7%)에서는 급성 치핵 혈전증에 의한 통증으로 응급 수술을 하였고, 또 다른 1예(4.7%)에서는 통증으로 인해 결찰한 밴드를 제거하였다. 대량 출혈로 인해 수혈 혹은 재입원을 요하는 환자는 없었다. 시술 후 발열은 1예(3.3%)에서 관찰되었고, 항생제와 해열제 사용 후 3일째 호전되었다. 결론: 내치핵 치료에 있어서 EBL은 효과적이고 비교적 안전한 시술이다. 향후 EBL에 대한 장기간의 전향적이고, 대규모의 비교 연구가 필요할 것으로 판단된다.
