Abstract

Objective: The first aim was to describe the incidence and severity of surgical complications following peripheral lymphadenectomy in dogs. The second was to compare three surgical techniques: unassisted lymphadenectomy, intraoperative guidance by methylene blue dye alone (MB) or by a combination of γ-probe and MB (γ-MB). The third was to assess whether the number, palpability, and site of lymph nodes (LNs) influenced the incidence of complications.

Study design: Retrospective multicenter study.

Sample population: Lymphadenectomies (n = 201) from 163 client-owned tumor-bearing dogs.

Methods: Medical records of dogs undergoing both preoperative sentinel LN (SLN) mapping and excision of peripheral SLNs between December 2020 and April 2023 were reviewed. Signalment, intraoperative assistance technique, number of LNs, surgical time, postoperative treatments, site, and timing of complications observed were collected.

Results: Seventy-two (36%) lymphadenectomies were performed without assistance, 24% with MB and 40% with γ-MB. The overall incidence of surgical complications was 7.5%, of which 80% were mild. The most frequent complication was seroma (2.5%). None of the variables considered in the logistic regression model, including intraoperative guidance, influenced the complication rate (p = .255). Using the decision tree statistical model, mandibular and retropharyngeal lymphadenectomy affected the complication rate when surgery lasted more than 21.5 min.

Conclusion: Lymphadenectomy of peripheral LNs was associated with a low rate of mild complications, regardless of intraoperative assistance. Mandibular and retropharyngeal lymphadenectomies lasting more than 21.5 min may result in more complications.

Clinical significance: Lymphadenectomy of superficial LNs is a safe procedure that is easy to perform in most cases, even without intraoperative assistance.

163只犬外周前哨淋巴结切除术:术后手术并发症及术中清扫技术比较。
目的:第一个目的是描述狗周围淋巴结切除术后手术并发症的发生率和严重程度。第二是比较三种手术技术:无辅助淋巴结切除术,术中单独亚甲基蓝染料(MB)或γ-探针和MB (γ-MB)联合引导。第三是评估淋巴结(LNs)的数量、触感和位置是否影响并发症的发生率。研究设计:回顾性多中心研究。样本人群:来自163只客户拥有的肿瘤犬的淋巴结切除术(n = 201)。方法:回顾2020年12月至2023年4月期间接受前哨淋巴结(SLN)术前定位和周围SLN切除术的犬的医疗记录。收集观察到的并发症的信号、术中辅助技术、ln数、手术时间、术后治疗、部位和时间。结果:72例(36%)的淋巴结切除术是在没有辅助的情况下进行的,24%的人使用MB, 40%的人使用γ-MB。手术并发症的总发生率为7.5%,其中80%为轻度并发症。最常见的并发症是血清肿(2.5%)。在logistic回归模型中,包括术中指导在内的所有变量均未影响并发症发生率(p = 0.255)。采用决策树统计模型,下颌及咽后淋巴结切除术对手术时间超过21.5 min的并发症发生率有影响。结论:无论术中有无辅助,外周淋巴结切除术的轻度并发症发生率较低。下颌骨和咽后淋巴结切除术持续时间超过21.5分钟可能导致更多的并发症。临床意义:浅表淋巴结切除术是一种安全的手术,在大多数情况下易于操作,甚至无需术中辅助。

期刊介绍: Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations. It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
