Opportunistic salpingectomy (OS) is the removal of fallopian tubes during hysterectomy for benign indications or instead of tubal ligation, for the purpose of preventing ovarian cancer. We determined rates of OS at the time of hysterectomy and tubal sterilization and examined how they changed over the study period.
Using data from the Canadian Institute for Health Information's Discharge Abstract Database and National Ambulatory Care Reporting System for all Canadian provinces and territories (except Quebec) between the fiscal years 2011 and 2016, we conducted a descriptive analysis of all patients aged 15 years or older who underwent hysterectomy or tubal sterilization. We excluded those with diagnostic codes for any gynecologic cancer and those who underwent unilateral salpingectomy. We examined the proportion who had OS during their hysterectomy and compared the proportion of tubal sterilizations that were OS with the proportion that were tubal ligations.
A total of 318 528 participants were included in the study (mean age 42.5 yr). The proportion of hysterectomies that included OS increased from 15.4% in 2011 to 35.5% by 2016. With respect to tubal sterilization, the rate of OS increased from 6.5% of all tubal sterilizations in 2011 to 22.0% in 2016. There was considerable variation across jurisdictions in 2016, with British Columbia having the highest rates (53.2% of all hysterectomies and 74.0% of tubal sterilizations involved OS).
The rates of OS increased between 2011 and 2016, but there was considerable variation across the included jurisdictions. Our study indicates room for rates of OS to increase across many of the included jurisdictions.
机会性输卵管切除术（OS）是在因良性指征行子宫切除术时切除输卵管，或者替代输卵管结扎术，以预防卵巢癌。我们确定了子宫切除术和输卵管绝育术时行 OS 的比率，并研究了其在研究期间的变化情况。
我们利用加拿大卫生信息研究所的出院摘要数据库和除魁北克省以外的所有加拿大省和地区的国家门诊护理报告系统的数据，对 2011 年至 2016 年期间所有 15 岁或以上接受子宫切除术或输卵管绝育术的患者进行了描述性分析。我们排除了患有任何妇科癌症诊断代码的患者和接受单侧输卵管切除术的患者。我们检查了在子宫切除术期间行 OS 的患者比例，并比较了行 OS 的输卵管绝育术与行输卵管结扎术的比例。
本研究共纳入 318528 例患者（平均年龄 42.5 岁）。在子宫切除术期间行 OS 的比例从 2011 年的 15.4%增加到 2016 年的 35.5%。就输卵管绝育术而言，OS 的发生率从 2011 年所有输卵管绝育术的 6.5%增加到 2016 年的 22.0%。2016 年，各司法管辖区之间的差异很大，不列颠哥伦比亚省的比率最高（所有子宫切除术中有 53.2%涉及 OS，所有输卵管绝育术中有 74.0%涉及 OS）。
2011 年至 2016 年期间，OS 的比率有所增加，但各纳入司法管辖区之间存在较大差异。我们的研究表明，许多纳入的司法管辖区都有增加 OS 比率的空间。
