[PMID: 36541210 DOI: 10.1080/00365521.2022.2157222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 11/22/2022] [Accepted: 12/06/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND AND AIM Endoscopic biopsies can be taken using either single or double bite technique. In the single bite method, intubation time may be proportionately prolonged depending upon the number of biopsies taken. In contrast to this, double bite, though a greater number of biopsies may be taken per unit time, it may influence the quality of the biopsy specimen. The aim of the study was to compare these methods and to see if taking double bite has significant effect on the histological quality of the endoscopic biopsies. METHODS A prospective, randomised and partly blind study (n = 135, M: 54%, age 21-91 years) divided into two equal arms to compare 144 procedures was conducted. Specimen were compared for time taken to size, depth, crush artefacts, necrosis, fragmentation, distortion, and epithelial stripping. Time taken to collect specimens was also recorded in the upper GI procedures. RESULTS No significant difference was observed in the histological quality of single and double bite specimens (p < 0.05). However, DB took significantly less time (M = 88.5, SD ± 28.5) as compared to SB (M = 180, SD ± 55.9) (p < 0.05). CONCLUSIONS There is no difference between the histological quality of DB and SB and the former technique takes less time, hence reducing intubation time.

ACVIM consensus statement guidelines on diagnosing and distinguishing low-grade neoplastic from inflammatory lymphocytic chronic enteropathies in cats. J Vet Intern Med 2023; 37:794-816. [PMID: 37130034 PMCID: PMC10229359 DOI: 10.1111/jvim.16690] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Accepted: 03/10/2023] [Indexed: 05/03/2023] Open
Abstract
BACKGROUND Lymphoplasmacytic enteritis (LPE) and low-grade intestinal T cell lymphoma (LGITL) are common diseases in older cats, but their diagnosis and differentiation remain challenging. OBJECTIVES To summarize the current literature on etiopathogenesis and diagnosis of LPE and LGITL in cats and provide guidance on the differentiation between LPE and LGITL in cats. To provide statements established using evidence-based approaches or where such evidence is lacking, statements based on consensus of experts in the field. ANIMALS None. METHODS A panel of 6 experts in the field (2 internists, 1 radiologist, 1 anatomic pathologist, 1 clonality expert, 1 oncologist) with the support of a human medical immunologist, was formed to assess and summarize evidence in the peer-reviewed literature and complement it with consensus recommendations. RESULTS Despite increasing interest on the topic for clinicians and pathologists, few prospective studies were available, and interpretation of the pertinent literature often was challenging because of the heterogeneity of the cases. Most recommendations by the panel were supported by a moderate or low level of evidence. Several understudied areas were identified, including cellular markers using immunohistochemistry, genomics, and transcriptomic studies. CONCLUSIONS AND CLINICAL IMPORTANCE To date, no single diagnostic criterion or known biomarker reliably differentiates inflammatory lesions from neoplastic lymphoproliferations in the intestinal tract of cats and a diagnosis currently is established by integrating all available clinical and diagnostic data. Histopathology remains the mainstay to better differentiate LPE from LGITL in cats with chronic enteropathy.

Abstract
BACKGROUND Intestinal fibrosis (IF) is commonly identified on histopathology of intestinal biopsy specimens (IBSp) from cats with chronic inflammatory enteropathy (CIE) however, its clinical relevance is unknown. OBJECTIVES Characterize and determine the clinical relevance of IF in cats with CIE. ANIMALS Sixty-five client-owned cats diagnosed with CIE after gastrointestinal histopathology from a single referral hospital in the United Kingdom. METHODS Medical records were retrospectively searched for cases of CIE on the basis of histopathology of IBSp. The IBSp from eligible cats were re-reviewed by a single board-certified veterinary pathologist for inclusion. Masson's trichrome (MT) stain and immunohistochemical labeling using antivimentin and anticollagen I antibodies to identify IF. For each case, various variables at the time of diagnostic investigation were recorded and referring veterinarians were contacted for follow-up information. RESULTS Mucosal fibrosis was identified in 51% of duodenal and 76% of colonic hematoxylin and eosin (HE)-stained IBSp. Vimentin labeling and MT staining identified additional cases of IF in 65% and 58% of the duodenal biopsy specimens, respectively. Vimentin labeling detected IF in 79% of the colonic biopsy specimens. Positive vimentin labeling and MT staining of the colonic mucosa were associated with decreased likelihood of attaining clinical remission and increased risk of death because of CIE (P < .05). CONCLUSIONS AND CLINICAL IMPORTANCE Additional stains at initial histopathologic examination of IBSp allow for better identification of IF compared to routine HE staining. Identification of IF in colonic biopsy specimens by vimentin immunolabeling and MT staining may provide prognostic information in cats with CIE.

Abstract
Differentiation of feline inflammatory bowel disease and intestinal small cell lymphoma can be challenging, and some clinicians argue that it is unnecessary because prognosis and treatment are similar. Differentiation of feline inflammatory bowel disease and intestinal small cell lymphoma can be challenging and some clinicians argue that it is unnecessary since prognosis and treatment are similar. Altough the body of research on this topic has increased over time, we still know little about etiopathogenesis, progression, alternative treatment modalities and prognosis of the different forms of FCE. While differentiating IBD from SCL might not alter a single patients' disease course, further research efforts are required to alter the disease course for our feline patient population as a whole.

Abstract
Feline chronic enteropathy is a common disorder, especially in the senior cat population, with rising incidence over the past decade. Feline chronic enteropathy is considered an umbrella term comprising different diseases including food-responsive enteropathy, idiopathic inflammatory bowel disease and alimentary small cell lymphoma. However, differentiation between those diseases is often difficult in practice. This review will discuss the clinical approach to cats with chronic enteropathy, state-of-the-art diagnostic tests and pitfalls thereof as well as current therapeutic approaches. Although, much of the etiopathogenesis is still unknown, increased research efforts in this field have brought new insights into diagnostic and therapeutic options for these cats.

Abstract
The Indian Association of Pathologists and Microbiologists (IAPM) and Indian Society of Gastroenterology (ISG) decided to make a joint consensus recommendation for handling, processing, and interpretation of SI biopsies for the diagnosis and management of celiac disease (CD) recognizing the inhomogeneous practice of biopsy sampling, orientation, processing, and interpretation. A modified Delphi process was used to develop this consensus document containing a total of 42 statements and recommendations, which were generated by sharing the document draft, incorporating expert's opinion, followed by three cycles of electronic voting as well as a full-day face-to-face virtual ZOOM meeting and review of supporting literature. Of the 42 statements, 7 statements are on small intestinal (SI) biopsy in suspected patients of CD, site and the number of biopsies; 7 on handling, fixative, orientation, processing, and sectioning in pathology laboratories; 2 on histological orientation; 13 statements on histological interpretation and histological grading; 3 on the assessment of follow-up biopsies; 2 statements on gluten-free diet (GFD)-nonresponsive CD; 4 on challenges in the diagnosis of CD; 2 statements each on pathology reporting protocol and training and infrastructure in this area. The goal of this guideline document is to formulate a uniform protocol agreed upon both by the experienced pathologists and gastroenterologists to standardize the practice, improve the yield of small bowel biopsy interpretation, patients' compliance, overall management in CD, and generate unified data for patient care and research in the related field.

Abstract
BACKGROUND In clinical practice, histopathological diagnosis of chronic intestinal disease is challenging because of difficulty in obtaining adequate duodenal samples. At present, no studies have investigated the influence of biopsy forceps size on sample quality in cats. OBJECTIVES Duodenal biopsy using larger biopsy forceps (2.4 mm) will provide higher quality samples. ANIMALS Fifty client-owned cats underwent endoscopy of the upper gastrointestinal tract for evaluation of chronic gastrointestinal signs, with inflammatory bowel disease (IBD) or intestinal lymphoma as differential diagnoses. METHODS For each cat, duodenal biopsy specimens were obtained using both small (1.8 mm) and large (2.4 mm) forceps and evaluated for adequacy, orientation, the presence of artifacts, villi morphology, the presence of inflammation, and neoplastic infiltration. RESULTS The percentage of adequate and evaluable biopsy specimens obtained using the larger forceps was significantly higher than that collected using the smaller forceps. Agreement between the forceps was variable for histological features and substantial in the case of lymphoma. However, in case of disagreement, the proper diagnosis usually was achieved only with the larger biopsy forceps. CONCLUSIONS AND CLINICAL IMPORTANCE Use of a larger biopsy forceps allows collection of a higher percentage of adequate and evaluable biopsy specimens compared to the commonly used smaller forceps and indirectly decreases the percentage of artifacts and increases the percentage of samples with evaluable villi. The use of a larger forceps could be helpful to obtain high-quality samples and improve diagnostic accuracy.

Abstract
Various types of endoscopic biopsy forceps have been investigated in dogs. The Multibite (MB) are multiple-bite forceps that collect up to four tissue specimens in a single pass through the endoscope, reducing procedure time. The authors prospectively investigated its clinical utility by comparing procedure times and diagnostic quality of samples obtained with the MB to that of biopsies performed with a single-bite forceps (SB), in 21 dogs with gastrointestinal disorders. When comparing the depth, crush artefacts and diagnostic adequacy of the gastric and duodenal biopsies, there was no significant difference between the MB and SB forceps. The procedure time was significantly longer with the MB. There was no learning curve effect, and there were no reported adverse events. This study failed to demonstrate any significant clinical advantage associated with the use of the Multibite forceps over that of conventional disposable SB forceps.
