After salpingectomy, recurrent ectopic pregnancies occur in the contralateral fallopian tube. Here, we present a case of ipsilateral remnant fallopian tube pregnancy in a 30-year-old woman with a history of incomplete prior operation to remove the middle region of the left fallopian tube following fallopian tube isthmus pregnancy 6 years earlier. During the previous salpingectomy, the left fallopian tube was not completely observed because of adhesions to the pelvic peritoneum and sigmoid colon; a partial remnant may have been present. The patient presented with lower abdominal pain 6 weeks after the most recent menstrual cycle, and transvaginal ultrasonography revealed a remnant left fallopian tube ectopic pregnancy. A 4 cm-sized mass identified at the distal end of the remnant left fallopian tube and the proximal remnant tube were laparoscopically removed. The possibility of an ipsilateral remnant tubal pregnancy should be carefully considered in spontaneous pregnancy after partial fallopian tube resection.
输卵管切除术后，对侧输卵管会发生复发性异位妊娠。在此，我们报告一例30岁女性同侧残留输卵管妊娠的病例，该女性6年前曾因输卵管峡部妊娠接受过不完全手术，切除了左侧输卵管中部。在之前的输卵管切除术中，由于与盆腔腹膜和乙状结肠粘连，左侧输卵管未被完全观察到；可能存在部分残留。患者在最近一次月经周期后6周出现下腹痛，经阴道超声检查发现左侧残留输卵管异位妊娠。在腹腔镜下切除了左侧残留输卵管远端发现的一个4厘米大小的肿块以及近端残留输卵管。在部分输卵管切除术后自然妊娠时，应仔细考虑同侧残留输卵管妊娠的可能性。
