Abstract

Aims: To compare surgical times and rates of intra-operative and post-operative complications for open ovariohysterectomy (OVH) in female rabbits using conventional ligatures or a vessel sealing device (VSD) for haemostasis.

Methods: Female pet rabbits (n = 23) presented for OVH for either desexing or treatment of reproductive disorders were randomly assigned to a conventional ligatures (CL) group (n = 12) or a LigaSure 5-mm (LS5) group (n = 11). In the CL group, the ovarian pedicles were ligated with a single surgeon's knot. After transection of the ovarian pedicles, the broad ligament was manually broken down along the uterine horns to their respective cervices. In the LS5 group, both ovarian pedicles and the broad ligaments were sealed with a LigaSure Dolphin Tip VSD with 5-mm forceps. All the rabbits were hospitalised for 24 hours after surgery. Two weeks after discharge, a clinical recheck examination was performed. Incision length, overall surgical time (from initial incision to completion of intradermal suturing), OVH time (from identification of the first ovary to transection of the vaginal vault), and intra- and post-operative complications were recorded and compared between groups, using the Student's t-test for normally distributed continuous data, the Wilcoxon-Mann-Whitney test for non-normally distributed continuous data and Pearson's χ² test for categorical data.

Results: The mean overall surgical time was 14.1 (SD 4.4) minutes. The surgery took 15.0 (SD 4.9) minutes in the CL group and 13.1 (SD 3.8) minutes in the LS5 group (p=0.10). The OVH time was shorter in the LS5 group (mean 4.2 (SD 0.9) minutes) than in the CL group (mean 6.3 (SD 1.7) minutes; p = 0.005). No intra-operative complications were encountered in the LS5 group. Haemorrhage occurred in three rabbits in the CL group. One rabbit in the LS5 group developed steatonecrosis post-operatively. There was no evidence of a difference in the proportion of rabbits that experienced intra- and post-operative complications (p = 0.25 and p = 0.94 respectively) between groups.

Conclusions: The use of a LigaSure 5-mm VSD and conventional ligatures during open OVH were both associated with similar overall surgical times and complication rates. The OVH times were shorter in the LS5 group compared to the CL group.

Clinical relevance: Use of the LigaSure 5-mm VSD allows efficient haemostasis while performing open OVH in female pet rabbits.

兔开放式卵巢子宫切除术中传统结扎和血管封堵器止血的比较。

目的：比较使用传统结扎或血管封堵器（VSD）止血的雌兔开放式卵巢子宫切除术（OVH）的手术时间以及术中和术后并发症的发生率。方法：雌性宠物兔（n = 23）被随机分配到常规结扎（CL）组（n = 12）或LigaSure 5-mm（LS5）组（n = 11）。在CL组中，用一个外科医生的结结扎卵巢蒂。切断卵巢蒂后，用手将宽韧带沿着子宫角分解到各自的子宫颈。在LS5组中，用LigaSure Dolphin Tip VSD和5mm钳子密封卵巢蒂和宽韧带。所有兔子住院24小时手术后数小时。出院两周后，进行了临床复查检查。记录切口长度、总手术时间（从初始切口到皮内缝合完成）、OVH时间（从第一个卵巢的识别到阴道拱顶的横切）以及组间和术后并发症，并对正态分布的连续数据进行Student t检验进行比较，非正态分布连续数据的Wilcoxon-Mann-Whitney检验和分类数据的Pearsonχ2检验。结果：平均总手术时间为14.1分钟（SD 4.4）。CL组的手术时间为15.0（SD 4.9）分钟，LS5组为13.1（SD 3.8）分钟（p=0.10）。LS5组的OVH时间（平均4.2（SD 0.9）分钟）短于CL组（平均6.3（SD 1.7）分钟）；p = 0.005）。LS5组未出现术中并发症。CL组有3只兔子出现出血。LS5组中的一只兔子在术后出现了脂肪变性。没有证据表明兔子出现术中和术后并发症的比例有差异（p = 0.25和p = 0.94）。结论：在开放性OVH中使用LigaSure 5mm VSD和传统结扎术的总手术时间和并发症发生率相似。与CL组相比，LS5组的OVH时间更短。临床相关性：在雌性宠物兔中进行开放性OVH时，使用LigaSure 5-mm VSD可以有效止血。
