Background: Pathologic changes of the enteric nervous system of the stomach have been described in gastroparesis. Because the enteric nervous system lies within the myenteric plexus between the muscle layers of the stomach, it is not accessible by standard biopsy forceps. Thus, tissue must be obtained by laparoscopy or laparotomy. Obtaining full-thickness biopsies with a less-invasive method would be an ideal alternative.
ULTRASONOGRAPHIC ASSESSMENT OF LONG-TERM ENTERECTOMY SITES IN DOGS
Veterinary Radiology & Ultrasound, 2010
Twenty-eight enterectomy sites from 28 dogs were evaluated sonographically 6 months postoperatively or later. The longest time between the enterectomy and sonography was nearly 7 years. The enterectomy site was visible sonograpically in 22/28 (78.6%) dogs. The enterectomy scar typically appeared as mild focal intestinal wall thickening (90.9%) with altered (90.9%) or absent wall layering (9.1%) over a short distance of the bowel (median 1.2 cm, range from 0.6 to 2.5 cm). Intramural hyperechoic foci, most likely representing fibrosis or nonabsorbed suture material were noted in 63.6% of the visible enterectomy sites. A focal accumulation of intraluminal gas was often seen (81.8%) at the enterectomy site. Additional ultrasonographic features included the presence of an irregular hyperechoic rim bordering the enterectomy site (50 %), and a focal deviation of the intestinal course (45.5%). These descriptive features may assist ultrasonographers in differentiating a previous enterectomy site from other focal intestinal changes. r
Comparison of routinely used intestinal biopsy forceps in dogs: anex vivohistopathological approach
Journal of Small Animal Practice, 2017
Results of this study were partially presented as a poster at the ECVIM congress in 2013 in Liverpool, UK. This poster was awarded with the 2nd prize of the best poster of the congress. Recently, the impact of different BF on duodenal biopsies has a These authors contributed equally. OBJECTIVES : To compare the quality of duodenal and ileal samples obtained with different biopsy forceps. METHODS : Fifteen dogs were included in a prospective ex vivo study. After euthanasia, the duodenum and the ileum were sampled with four different forceps and evaluated according to a standardised scoring system. The biopsy forceps evaluated had alligator jaws or cups with smooth edge with or without a needle. RESULTS : The global quality of the biopsies was better in the ileum that in the duodenum regardless of the biopsy forceps. Biopsy forceps with smooth edge including a needle resulted in fewer artefacts than biopsy forceps with smooth edge but no needle in both sites and those with alligator jaws without a needle provided deeper biopsies than those with smooth edge without a needle only in the duodenum. There was no effect of the biopsy forceps type on the size of the biopsies.

Nowadays, endoscopic examination is a diagnostic tool gaining popularity in the management of gastrointestinal disorders in dogs and cats. Direct accessibility of the lumen of gastrointestinal tract combined with the mucosal biopsy provides a great diagnostic potential. Using endoscopy and endoscopically guided biopsy, one can conduct both macro- and microscopic assessment of lesions and perform many specialist adjunct examinations. Histopathological examination of mucosal biopsy specimens collected from the stomach and intestines allows us to distinguish between types of inflammations and to diagnose ulcerative, polypoid, and cancerous lesions.
Study of Gastric Biopsies with Clinicopathological Correlation – a Tertiary Care Centre Experience
Journal of Evidence Based Medicine and Healthcare, 2016
BACKGROUND Gastric disorders are one of the most commonly encountered problems in clinical practice. A variety of disorders can affect the stomach and gastrointestinal tract. The definitive diagnosis of gastric disorders rests on the histopathological confirmation and is one of the basis for planning proper treatment. OBJECTIVES To determine the spectrum of histopathological lesions of gastric region. To establish endoscopic biopsies as an effective tool in the proper diagnosis and management of various gastric lesions. MATERIALS AND METHODS A retrospective study was conducted on the gastric endoscopic biopsies and the histopathological assessment was done at the
Postoperative Ultrasonographic Appearance of Uncomplicated Enterotomy or Enterectomy Sites in Dogs
Veterinary Radiology & Ultrasound, 2008
The ultrasonographic findings in 20 dogs with 25 healing enterotomy and enterectomy sites resulting from the removal of foreign material or correction of intussusceptions are presented. In this prospective study, dogs had preoperative abdominal ultrasound examinations followed by sequential sonographic examinations on the first, third, sixth, and 10th days postenterotomy or enterectomy with an additional sonographic examination after 20 days postoperatively. Documented sonographic features included length and maximal intestinal wall thickness of the enterotomy or enterectomy sites, echogenicity of omental/mesenteric fat, amount of free gas and abdominal effusion, and gastrointestinal motility. Sonographically, 57% of enterotomies and 100% of enterectomies were visualized. Pneumoperitoneum, hyperechoic omental/mesenteric fat, and abdominal effusion did not appreciably hamper evaluation of the intestinal surgical site. Absent wall layering at the surgical site was noted in 96% of dogs at day 1 postoperatively. At the final sonographic examination, wall layering remained altered to absent in 100% of dogs and normal thickness was noted in only 20% of dogs. The median maximal wall thickness was 7 and 8 mm for enterotomies and enterectomies respectively, which occurred between days 1 and 3 and days 3 and 6 postoperatively. Effusion and increased echogenicity of omental/mesenteric fat localized to the surgical site were noted in 42% and 60% of dogs respectively at day 1 postoperatively, with resolution noted between days 3 and 10 postoperatively in 92% and 80% of dogs. Generalized abdominal effusion and pneumoperitoneum were seen in 100% of dogs immediately postoperatively and resolved in 80% by day 10.
Evaluation of Endoscopic Biopsies of Gastro Intestinal Tract-A Clinico Pathological Study
Aims and objectives: To study the endoscopic biopsies of gastrointestinal lesions, to assess the overall utility of endoscopic biopsy in gastro-intestinal lesions and to study the various gastro intestinal lesions in relation to age and sex of the patients, site of occurance and distribution. Materials & methods: A total number of 100 cases of esophageal lesions are clinically identified and subjected to endoscopic biopsy, the over a period of two years from 1999 to 2001.Observations: Out of 100cases of gastro intestinal lesions, male patients are 64 and female patients are 36 with male to female ratio of 1.8:1. In the100 cases of gastro intestinal lesions 43(43%) cases were esophageal lesions, 34(34%) cases were gastric lesions, 5(5%) cases were duodenal lesions and 18 (18%) cases were colo rectal lesions. Conclusion: Endoscopic biopsy is the safest, non-invasive, affordable and time saving investigating procedure of choice to obtain a preoperative diagnosis in both neoplastic and non neoplastic lesions of gastro intestinal tract.
