研究慢性输卵管炎的造影表现，提高子宫输卵管造影术（HSG）对输卵管性不孕的诊断能力，并对输卵管妊娠患者再次备孕提供指导。

回顾性分析2018年1月至2019年8月在我院就诊的既往有输卵管妊娠史患者的资料，共计58例，115条输卵管，其中输卵管妊娠患病64条。在月经干净以后3～7 d内进行HSG检查，观察输卵管通畅度、形态学变化以及延时期输卵管内是否有对比剂滞留，并比较病程长短对阳性检出率的影响。

输卵管通畅度方面，有7条输卵管积水形成，57条输卵管仍保持通畅；输卵管逆向蠕动功能不良共计21条；输卵管形态学异常包括壶腹部迂曲团绕、管腔扩张或狭窄、变形或憩室形成，26条输卵管无形态学异常；病程≤12个月组和> 12个月组两组资料阳性检出率无明显差异（χ² = 0.123，P > 0.500）。

慢性输卵管炎是输卵管妊娠和输卵管性不孕的主要病因，HSG应围绕输卵管通畅度、输卵管形态和蠕动功能3个方面进行研究。输卵管妊娠后，可能短期内病变基础已经形成，不会随着时间延长发生明显变化，建议输卵管妊娠后如有再生育需求，应及早进行HSG，以免延长备孕时间。

To study the imaging findings of chronic salpingitis, improve the diagnostic ability of hysterosalpingography (HSG) for tubal infertility, and provide guidance for patients with tubal pregnancy to prepare for pregnancy again.

The data of 58 patients with previous tubal pregnancy in our hospital from January 2018 to August 2019 were retrospectively analyzed, including 115 fallopian tubes, of which 64 were tubal pregnancy. HSG was performed within 3-7 days after menstruation to observe the tubal patency, morphological changes and whether there was contrast agent retention in the fallopian tube during the extended period, and the effect of the duration of the disease on the positive detection rate was compared.

In terms of tubal patency, there were 7 fallopian tubes with hydrosalpinx, 57 tubes remained unobstructed; there were 21 tubes with retrograde peristalsis dysfunctions; the morphological abnormalities of fallopian tubes included ampulla tortuosity, lumen dilatation or stenosis, deformation or diverticulum formation, 26 fallopian tubeshad no morphological abnormalities. There was no significant difference in the positive detection rate between the two groups in the course of disease less than 12 months and more than 12 months (χ² = 0.123, P > 0.500).

Chronic salpingitis is the main cause of tubal pregnancy and tubal infertility. HSG should focus on tubal patency, tubal morphology and peristaltic function. After tubal pregnancy, the pathological basis may have been formed in a short time, and will not change significantly with the extension of time. It is suggested that HSG should be carried out as soon as possible if there is a need for reproduction after tubal pregnancy, to avoid prolonging the pregnancy preparation time.
