The evaluation of loco-regional lymph nodes (LN) plays an important prognostic role and assists the clinical decision making in canine cancer patients. Excision of non-palpable LN can be challenging. The aim of the study was to evaluate surgical time, successful excision rate and surgical complications associated with the use of an ultrasound-guided hook-wire (UGHW) LN localization method for non-palpable superficial inguinal LN (SILN) in dogs. Dogs that presented for excision of non-palpable SILN, performed with the aid of an UGHW placement, were enrolled. Information including signalment, SILN width, UGHW placement and surgical procedure time, hook-wire position, successful excision and intra- and post-operative complications were reviewed. Seventeen dogs were enrolled. Median LN width was 3 mm (range 2-11). Median time of preoperative UGHW placement and surgical LN excision was 8 min and 15 min, respectively. Successful SILN excision was achieved in all cases. Two minor intra-operative (hook migration and wire fragmentation) and one minor post-operative complications (seroma) were observed. No major intraoperative or post-operative complications occurred. The UGHW LN localization method is safe and effective and may allow a high rate of successful SILN excisions in dogs. This method has the potential to facilitate LN excision for other superficial LN locations.
局部区域淋巴结（LN）的评估在犬类癌症患者的预后中起着重要作用，并有助于临床决策。切除触诊不可及的LN可能具有挑战性。本研究的目的是评估使用超声引导下钩线（UGHW）LN定位方法对犬触诊不可及的浅表腹股沟LN（SILN）进行定位时的手术时间、成功切除率和手术并发症。纳入了因借助UGHW定位而进行触诊不可及的SILN切除的犬只。回顾了包括特征、SILN宽度、UGHW定位和手术操作时间、钩线位置、成功切除情况以及术中和术后并发症等信息。共纳入17只犬。LN宽度中位数为3mm（范围2 - 11mm）。术前UGHW定位和手术切除LN的时间中位数分别为8分钟和15分钟。所有病例均成功切除SILN。观察到2例轻微术中并发症（钩移位和钢丝断裂）和1例轻微术后并发症（血清肿）。未发生重大术中和术后并发症。UGHW LN定位方法安全有效，可能使犬类SILN的成功切除率较高。该方法有可能便于对其他浅表LN部位进行LN切除。
