Methods We retrospectively analyzed the medical records of 65 patients who were diagnosed to hydrosalpinx by hysterosalpingogram. Among 65 patients who diagnosed to hydrosalpinx, 38 patients were received surgical treatment (surgical treatment group). Otherwise, 27 patients didn t received any surgical treatment and classified as no treatment group. After then, surgical treatment group was subgrouped into two groups according to their method of surgery such as salpingoneostomy group (n = 29) and salpingectomy group (n = 9). Then we analyzed several factors related to pregnancy of each group. Results There were no statistically significant differences in age, duration of infertility, fertility history and causes of infertility between groups. The in vitro fertilization (IVF) success rate in salpingectomy group (77.8%) was significantly higher than that of no treatment group (34.8%) (P=0.035). Conclusion In infertile patients with hydrosalpinx, surgical treatment of hydrosalpinx seems to have beneficial effects to increase the success rate of pregnancy through IVF. Keywords: Infertility; Salpingoneostomy; Salpingectomy; Pregnancy rate; In vitro fertilization 불임의원인에는남성측요인이 50%, 여성측요인이 50% 가되고, 이중여성측요인을좀더세분화해보면배란장애와난관또는복강내요인이각각 30%-40% 를차지하고있다. 여성측난관요인으로인한불임의주요원인으로보고되고있는난관수종은골반강수술력, 골반염증성질환의과거력, 자궁내막증, 복막염의과거력등이있는경우정상난관에유착이생기면서난관채가막히게되고, 난관내강의세포가분비하는액이폐색된난관내에고이게되면서원위부난관이팽창하여발생하게된다 [1]. 이런난관수종은일차로는폐색된난관으로인한난자의포획을방해하고, 또난관수종내에고인난관수종액이수정란의착상과배아의성장에부정적인영향을주어불임을야기한다. 이것은난관수종이있는환자에서체외수정시술의임신성공률이현저하게낮았다는대규모의메타분석연구결과로뒷받침될수있다 [1]. 난관수종은나팔관조영술이나진단적복강경검사등으로난관의폐 Received: 2012.5.26.

Choe와 Check [17], 그리고 Aboulghar 등 [18] 은한쪽난관수종절제술후자연임신율이증가하였다고보고하였으며, Sagoskin 등 [16] 도한쪽난관수종을절제하거나근위부에서폐쇄 (proximal tubal occlusion) 시켰을경우정상가임력으로의회복이매우효과적이었고, 특히수술후임신성공까지걸리는시간이현저히짧아졌다고보고하였다. 그리고난관절제술을시행한그룹과근위부난관폐쇄술을한그룹모두에서동일하게임신율이증가하였다는연구결과도있다 [19,20]. 이것은본연구에서도마찬가지로, 난관절제술을시행한그룹에서 77.8% 의체외수정시술을통한임신성공률을보임으로써대조군 (34.8%) 보다약 2배이상의높은체외수정시술성공률을보이고있다. 또, 체외수정시술의성공률을주기당으로분석하였을때도수술적치료를받은군이 43.8% 로수술적치료를받지않은군 (20%) 에비해높은체외수정시술성공률을보였다. 일반적으로가임력은연령이증가할수록감소한다고알려져있는데, 환자의연령에따라기저혈중난포자극호르몬 (follicle stimulating hormone) 의농도, 최고혈중 E 2 농도, 임상적임신율, 유산율, 착상률등에유의한영향을미친다고본다 [21]. 미국생식의학회의 2001년도통계조사에의하면남성불임요인이없는불임부부의체외수정시술시임신율, 출산율, 유산율은각각여성나이 35세미만에서 44.7%, 38.9%, 13.0%, 35-37세에서 39.5%, 32.9%, 13.0%, 38-40세에서 32.2%, 24.3%, 24.5%, 40세초과여성에서 19.1%, 11.1%, 41.6% 로나타나연령이증가함에따라임신율과출산율이감소하는경향을보였다 [22]. 본연구에서환자들의평균나이는난관신개구술을받은군이 31.8세로수술하지않은군과난관절제술을받은군 (34.1세 ) 에비해더젊은편이었으나, 통계학적으로유의한차이는보이지않았고 (P = 0.074), 또 E 2, 난포자극호르몬, 황체형성호르몬이각군사이에통계학적으로유의한차이가없었으므로나이에따른가임력에차이가없다고보고임신율향상평가에고려하지않았다. 사실, 난관절제술이나난관신개구술과같은수술적치료는전신마취의부담과침습적인시술로인한출혈등의위험부담이있다. 게다가유착이심한경우는수술자체가어려울수있으며, 어떤연구결과에따르면난관절제술을하는것이오히려난소로의혈류공급을줄이고, 성선자극호르몬에대한난소의반응을감소시킬수있다는우려도있다 [6,23,24]. 따라서난관수종의수술적치료가힘들다고여겨진다면초음파중재하난관수종액흡인술을고려해볼수도있다. 난관수종환자 66명을대상으로한어떤임의추출연구에따르면초음파중재하난관수종액흡인을시행한환자군에서시행하지않은환자군에비해생 932 WWW.KJOG.ORG
Ju Youn Bae, et al. The effect of hydrosalpinx treatment 화학적임신율이확실히향상되었다는보고가있다 (43.8% vs. 20.6%, P = 0.04). 그러나이연구에서임상적임신율은흡인을시행한그룹에 서증가하긴하였으나 (31.3% vs. 17.6%) 두그룹간에통계학적차이 가없었고 (P = 0.20), 또생화학적임신후의자연유산율도감소하였으 나 (28.6% vs. 42.9%) 두그룹간에통계학적의미는없었다 (P = 0.56) [5]. 하지만난관수종액을흡인해줌으로써난포의성숙및착상에긍 정적인영향을준다는연구결과 [25] 도있어난관수종의수술적치료 가힘들경우단순히체외수정시술만하는것보다초음파중재하난관 수종액흡인술을함께시도해보는것도임신율의향상에도움이될것 으로생각되며, 이에대해서는좀더연구가필요할것이다. 본연구는후향적으로진행되어난관수종진단이나수술당시에난 관수종의정도, 난관채의기능보존정도, 복강내유착정도등은파악 할수가없었다. 난관수종이심하지않고, 복강내유착이적고, 난관채 의기능이보존되어있을수록난관신개구술이후에난관이제기능을 할수있을것으로추측되는바 [26], 난관수종의중등도에대한자료도 함께수집하여난관신개구술후가임능력회복과의상관관계를알아 본다면더욱충실한연구가되었으리라생각한다. 또, 여러명의의사 들이수술하였고, 각각의수술방법이동일하지않으므로그에따른예 후의차이도변수로작용할수있겠지만본연구에서는고려하지않았 다. 또한, 본원의특성상타병원에서의뢰되어본원으로와난관수종 을진단및수술적치료를받은후다시연고지로돌아가추적관찰에 실패한환자들이약 38% 에달하는데, 이것은결과적으로연구대상환 자수가줄어들게한한계점이있다. 하지만본연구결과를토대로향후 전향적연구를시행하여이런한계를극복한연구를시행하고자한다.
