=목적: 복강경하 근종절제술이 적합하지 않은 거대근종에서 개복술을 대체하기 위한 술기로서 미니복부절개와 복강경하 병합술기 (LAMM)의 안정성과 유용성을 연구하고자 한다.연구 방법: 본원 내시경센터에서 미니복부절개와 내시경의 병합술기 (LAMM)를 통한 거대근종절제술을 시행받은 환자 46명을 대상으로 후향적 분석을 하였다. 수술방법은 크게 5단계로 구성된다: 1) 복강내 관찰, 2) 희석된 바소프레신의 대량주사요법 3) 근종의 박리, 4) 자궁결손부위의 봉합 및 촉진, 5) 근종의 복강외로의 제거. 복강내 관찰은 모두 내시경을 통해 시행하였고 나머지 단계는 환자의 특성에 따라 내시경 또는 미니복부절개를 통해 시행하였다. 술전 빈혈이 있는 환자는 경구 또는 정주 철분제로 빈혈을 교정하였다.결과: 환자들의 평균 나이는 33.3세, 평균 임신력과 분만력은 각각 0.74, 0.24였다. 46명의 환자 중 18명은 미혼이었으며 28명은 기혼이고, 20명이 임신을 원하였다. 수술적응증은 압박증상 17명, 급속히 자라는 종괴 14명, 비정상 자궁출혈 또는 월경과다 10명, 그리고 불임인 환자가 5명이었다. 평균 (±SD) 근종의 무게는 501±353 (130-1600) gm이었다. 평균 수술시간과 실혈량은 각각 87.0±31.3분, 208±239 mL였다. 평균 미니복부절개길이는 4.6±1.1 (2.5-6) cm였다. 술 후에 1예의 수술부위의 창상감염이 있었다. 술 후 경증 빈혈은 경구 철분제로 교정하였다. 대부분의 환자들은 3주 내에 일상생활로의 복귀가 가능하였다. 평균 추적관찰 기간은 20 (6-58)개월이었다. 20명의 임신을 원하는 환자 중, 15명이 추적관찰되었고 9명이 임신하였다. 6명의 환자가 제왕절개술을 통해 만삭 분만하였고 골반유착이나 자궁의 결손부위는 관찰되지 않았다.결론: 개복술을 대체하여 거대근종을 가진 환자의 최소침습적인 보존적인 술기로서 미니복부절개와 내시경의 병합술기를 통한 거대근종절제술 (LAMM)이 쉽고 안전하고 유용하다고 사료되어진다.
Abstract
Objective: To evaluate the effectiveness and feasibility of the laparoscopy assisted mini-lap myomectomy (LAMM) as an alternative to laparotomy for patients with multiple or huge myoma unsuitable for laparoscopic myomectomy. Methods: Uncontrolled retrospective study was done on the forty-six women with myoma of 16 or more gestational sized who were undertaken laparoscopy assisted mini-lap myomectomy. The operative procedures consisted of: 1) examination of pelvic cavity, 2) infiltration of diluted vasopressin, 3) enucleation of myoma, 4) suture of uterus, and 5) removal of myoma. The examination of pelvic cavity was always done using laparoscopy. Either the laparoscopic or mini-lap method for each of the remaining steps was determined depending on the characteristics of the cases. Before operation, patients with severe anemia were corrected by the administration of oral or parenteral iron. Results: The mean age of the patients was 33.3±4.7 years, their mean gravidities and parities were 0.74 and 0.24, respectively. Of 46 patients, 28 women were married and 20 desired childbearing. The mean (±SD) myoma weight was 501±353 (range 130- 1600) gm. The mean operation time was 87.0±31.3 minutes and blood loss was 208±239 mL. The mean incision length of mini- lap was 4.6±1.1 (range 2.5-6) cm. Postoperatively, 1 case of wound abscess occurred. Postoperative mild anemia was correctable with oral iron. Most patients were resumed normal activity within 3 weeks. The mean period of follow-up was 20 (range 6-58) months. Of 20 who desired childbearing, 15 women were follow-up and 9 women conceived. In 6 patients who underwent cesarean section, no significant adhesion or defect was found in the uterus. Conclusion: These results suggest that LAMM is feasible and safe minimal invasive method that could replace routine laparotomy in patients with huge myoma.
