Abstract

Objectives

The aim was to assess the technical success of percutaneous ultrasound-guided fine needle aspirates of gastrointestinal wall lesions and evaluate predictors of success. Secondary aims included comparing the cytological diagnosis with histopathology, evaluating the utility of concurrent locoregional lymph node cytology and assessing the procedure's complication rate.

Material and Methods

Gastrointestinal wall cytology from 75 dogs and 70 cats obtained between 2018 and 2023 were reviewed and categorised as successful (resulting in a diagnostic cytology report) and accurate (resulting in the correct diagnosis when compared to histopathology). Unsuccessful fine needle aspirates, not submitted for cytology, were not recorded. Variables recorded included animal signalment, lesion and lymph node's appearance on ultrasound, size, location, number of smears submitted and experience of the ultrasonographer.

Results

One hundred and fifty-two reports were analysed. Eighty-eight (58%) were successful: three normal epithelium, 21 inflammatory processes and 64 neoplasms. Variables associated with increased technical success included description of a mass, higher number of slides submitted and thickness of gastrointestinal lesion on ultrasound. Comparison with histopathology, performed for 17 lesions, showed discrepancies in eight, complete agreement in seven and partial in two. Eighty-four loco-regional lymph nodes were sampled, of which, 67 were successful (80%) and 52 brought additional clinical information (supporting GI wall cytology or diagnosing neoplasia not identified on GI wall cytology). No complication strictly attributable to gastrointestinal wall sampling was reported but when possibly related, death of the patient occurred in 2.5% of cases.

Clinical Significance

Ultrasound-guided fine needle aspirate of gastrointestinal wall had moderate accuracy and was unsuccessful in 42% of cases, but technical success increased when sampling mass lesions, thicker intestinal layers and submitting more slides.

经皮超声引导胃肠壁细针穿刺的诊断率：对 152 份样本的回顾性分析。

研究目的目的是评估经皮超声引导胃肠壁病变细针穿刺的技术成功率，并评估成功的预测因素。次要目的包括比较细胞学诊断与组织病理学，评估同时进行的局部淋巴结细胞学检查的效用，以及评估手术的并发症发生率：对2018年至2023年期间获得的75只狗和70只猫的胃肠壁细胞学检查进行回顾，并将其分为成功（获得细胞学诊断报告）和准确（与组织病理学相比获得正确诊断）两类。未提交细胞学检查的不成功细针穿刺未予记录。记录的变量包括动物信号、病变和淋巴结在超声波上的外观、大小、位置、提交的涂片数量以及超声波技师的经验：对 152 份报告进行了分析。结果：分析了 152 份报告，其中 88 份（58%）成功：3 份正常上皮、21 份炎症过程和 64 份肿瘤。与提高技术成功率相关的变量包括对肿块的描述、提交的切片数量较多以及超声显示胃肠道病变的厚度。与组织病理学的比较显示，17 个病变中有 8 个存在差异，7 个完全一致，2 个部分一致。对84个局部区域淋巴结进行了取样，其中67个取样成功（80%），52个提供了额外的临床信息（支持消化道壁细胞学检查或诊断消化道壁细胞学检查未发现的肿瘤）。没有严格归因于胃肠道壁取样的并发症报道，但在可能相关的情况下，2.5%的病例发生了患者死亡：临床意义：超声引导下胃肠壁细针穿刺的准确性一般，42%的病例没有成功，但在对肿块病变、肠道较厚层取样和提交更多切片时，技术成功率会提高。

期刊介绍： Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery. In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world. The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher. The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
