Abstract

The aim of this study is to describe the ultrasonographic features of feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) before histological diagnosis and during follow-up after surgical excision and/or medical treatment. This multicentric retrospective case series study includes medical records of cats diagnosed histologically, which had an ultrasound before diagnosis and a minimum of one follow-up ultrasound at least 4 weeks after treatment. Thirty cats were included in the study. The average age was 4.9 years (IQR 3.3-9.3 years). In 25 cases, the mass affected the gastrointestinal system, most commonly the proximal duodenum (36%: 9/25). Three masses originated from the lymph nodes, and two were mesenteric. The most common clinical signs were chronic vomiting, weight loss, and anorexia/reduced appetite. In 25 of 30 (83%) FGESF gastrointestinal cases, ultrasonographically, the lesions generally presented as focal, circumferential, eccentric masses with loss of layering, heterogeneous echogenicity, and hyperechoic areas. Hyperechogenicities in the peritoneum were observed in 63% of the cases, and enlarged lymph nodes (88%) were common. On final follow-up, 55% of the patients had complete resolution of the main lesion, peritoneal changes, and lymphadenopathies ultrasonographically. The disease recurred in 11 of 30 (37%), and progression was reported in 10 of 30 (33%) cases during the follow-up. Initially, 9 of these 10 were diagnosed via nonexcisional biopsy (endoscopic biopsy, Trucut biopsy, surgical incisional biopsy) and treated medically; only one patient had had surgical resection of the mass. Clinical signs at the time of recurrence or progression were inconsistent. Feline gastrointestinal eosinophilic sclerosing fibroplasia shows ultrasonographic features similar to neoplasia but commonly demonstrates hyperechoic areas. Data were assessed for normality and then assessed with appropriate parametric or nonparametric tests accordingly. Progression of the disease at any time during the follow-up was more common in cats treated medically than those treated surgically (P = .02). Clinical signs may or may not be present at the time of ultrasonographic recurrence or progression.

猫胃肠嗜酸性硬化性纤维增生症的超声表现及随访。
本研究旨在描述猫胃肠道嗜酸性硬化性纤维增生症(FGESF)在组织学诊断前以及手术切除和/或药物治疗后随访期间的超声波特征。这项多中心回顾性病例系列研究包括经组织学诊断的猫咪的医疗记录,这些猫咪在诊断前接受了超声波检查,并在治疗后至少 4 周接受了一次随访超声波检查。研究共纳入了 30 只猫咪。平均年龄为 4.9 岁(IQR 3.3-9.3 岁)。在 25 个病例中,肿块累及胃肠系统,最常见的是十二指肠近端(36%:9/25)。三个肿块来自淋巴结,两个来自肠系膜。最常见的临床症状是慢性呕吐、体重下降和厌食/食欲减退。在30例FGESF胃肠道病例中的25例(83%)中,超声病变一般表现为局灶性、环绕性、偏心性肿块,分层消失、回声不均和高回声区。63%的病例腹膜出现高回声,淋巴结肿大(88%)也很常见。在最后的随访中,55%的患者的主要病变、腹膜变化和淋巴结病变在超声波检查中完全消失。在随访期间,30 例患者中有 11 例(37%)病情复发,10 例(33%)病情恶化。最初,这 10 例中有 9 例是通过非切开活检(内窥镜活检、Trucut 活检、手术切开活检)确诊的,并接受了药物治疗;只有 1 例患者接受了肿块手术切除。复发或恶化时的临床症状不一致。猫胃肠道嗜酸性硬化性纤维增生症的超声特征与肿瘤相似,但通常表现为高回声区。对数据进行正态性评估,然后用相应的参数或非参数检验进行评估。在随访期间的任何时间,药物治疗的猫比手术治疗的猫更容易出现病情进展(P = .02)。临床症状在超声波复发或进展时可能出现,也可能不出现。
