Methods: The retrospective study was performed in those underwent TFTC from January 2005 to December 2009. A total of 342 fallopian tubes in 215 patients which showed tubal blockage in hysterosalpingography (HSG), were subjected to TFTC. Recanalization rate (RR) was compared according to portion of tubal blockage; proximal, isthmic and distal portion and blockage type; tapering, concave, and convex type. Results: In total, RR was 72.5% (248/342 tube). According to the portion of tubal blockage, RR was 83.8% in proximal, 45.6% in isthmic and 100% in distal portion. RR was 92.3% in tapering, 80.2% in concave and 25.5% in convex type, respectively. There were 98 pregnancies in 156 patients after successful recanalization, which shows 62.7% pregnancy rate. Conclusion: TFTC were capable of recanalizing tubal blockage in 248 of 342 tubes in 156 of 215 patients (72.5%). The RR was increased with proximal portion and tapering type tubal blockage. [Korean.

Rubin과 DeCherney는협부폐색과폐쇄의차이점에대해언급하여폐쇄 (occlusion) 는결절성협부난관염 (salpingitis isthmica nodosa) 이나난관내의섬유증 (intraluminal fibrosis) 의경우와같이진성으로해부학적막힘 (blockage) 이있음을일컫는것이고, 반면폐색은기능적막힘으로 Sulak 등 4 은 ' 무정형물질 (amorphous material)' 등이난관을일시적으로차단한상태를나타낸다고하였다.

대한생식의학회지 보였다. 난관막힘부위와형태를종합하여볼때난관근위부점진형막힘시가장높은개통률을보고한반면난관협부볼록형막힘시낮은개통률을보여근위부점진형난관막힘시우선적으로난관개통술을시행해볼수있다하겠다. 본연구에서는난관막힘형태를병리학적소견과연관지어고찰하지못하였지만점진형과오목형은 DeCherney 6 이기술했던폐색에해당하는예가많을것이라추정되며선택적난관조영술을우선적으로시도해볼수있고, 볼록형은기질적인병변을동반하는폐쇄의경우가많을것으로추정되며선택적난관조영술및난관개통술을시행해볼수있다. 난관개통술시개통이안된경우에는수술적치료나체외수정시술이치료법이될수있으리라생각된다. 앞으로병리학적고찰과연관된연구를통하여이러한내용을확인해나가는것이필요하겠다. 선택적난관조영술및난관개통술시난관천공의합병증은 3~11% 에이르는것으로알려져있으며 16,17 저자들도본연구에서도난관개통술시 13.2% 에서난관천공을동반하여유사한결과를보였으며별다른합병증없이치유되었다. 난관개통술이성공한 156명의환자가운데평균 2.5년의추적관찰을통하여 98명에서임신에성공하여 62.7% 의임신율을보고하여난관막힘에의한불임환자에서효과적인치료법이라하겠다. 아울러자궁경부를통한시술로수술적방법이나체외수정시술의난자채취에비해덜침습적인방법으로입원치료가필요없이시행할수있는시술로비교적적은비용으로불임의원인을극복할수있는장점이있어난관원인에의한불임환자에서우선적으로시행해볼수있는효과적인치료방법이라할수있다. 또한난관막힘부위가근위부이며막힘형태가점진형이거나오목형인경우에는선태적난관조영술및난관재개통술을일차적으로시행하여보는것이바람직할것으로생각된다. 참고문헌 1.
