Vessel sealing (VS) is well established in laparoscopic ovariectomy (OVE) in dogs. The objectives of this study were to evaluate the efficacy of ovarian pedicle haemostasis by VS using a commercially available VS tool in open OVE and compare it with suture ligation (SL). A prospective, randomised clinical trial including 20 female dogs was designed. Open OVE was performed via a standard mid-line celiotomy by a single surgeon using a standardised protocol. At random, the right ovarian pedicle was sealed (VS) or ligated (SL) whereas the left pedicle was treated by the alternative technique. Surgical times for procedural stages and intra-operative complications were recorded and statistically evaluated. Total surgical time was 29.28±11.13 minutes (range 12.50-62.13 minutes) and time from identification to removal of the ovary was significantly less when sealing (VS 2.22±0.58 minutes) than when ligating (SL 4.10±1.13 minutes P=0.0001). Intra-operative complications were rare for both techniques (failure of the electrode of the VS device (n=3); ovarian pedicle haemorrhage due to ligature slippage (n=1)). The results of the current study indicate that ovarian pedicle haemostasis achieved by VS is significantly faster than by placement of ligatures without appearing to compromise safety.
血管闭合（VS）在犬腹腔镜卵巢切除术（OVE）中已得到广泛应用。本研究的目的是评估在开放性OVE中使用市售VS工具进行卵巢蒂止血的疗效，并将其与缝合结扎（SL）进行比较。设计了一项包括20只雌性犬的前瞻性随机临床试验。由一名外科医生通过标准中线剖腹术，采用标准化方案进行开放性OVE。随机选择，右侧卵巢蒂进行闭合（VS）或结扎（SL），而左侧蒂采用另一种技术处理。记录手术各阶段的手术时间和术中并发症，并进行统计学评估。总手术时间为29.28±11.13分钟（范围12.50 - 62.13分钟），从识别卵巢到切除卵巢的时间，闭合时（VS 2.22±0.58分钟）明显短于结扎时（SL 4.10±1.13分钟，P = 0.0001）。两种技术的术中并发症都很少见（VS设备电极故障（n = 3）；结扎滑脱导致卵巢蒂出血（n = 1））。本研究结果表明，VS实现的卵巢蒂止血明显比结扎更快，且似乎不影响安全性。
