Foreign body‐associated intestinal pyogranuloma resulting in intestinal obstruction in four dogs

Abstract

Intestinal obstruction resulting from an intramural foreign body-associated pyogranuloma was diagnosed in four dogs. Vomiting and weight loss were the main clinical signs. On physical examination, a mass in the abdomen was detected in three dogs. Abdominal radiography demonstrated the presence of soft tissue opacity in three of the dogs and gas-filled dilated intestinal loops in all four dogs. Abdominal ultrasonography showed hyperkinetic fluid-filled dilated intestinal loops and a hypoechoic small intestinal mass in all the dogs. Exploratory coeliotomy confirmed the presence of a jejunal mass, which was removed by resection and anastomosis in all the dogs. In one of the dogs a linear foreign body was also found cranial to the mass and was removed through a separate enterotomy incision. The lesions were diagnosed as foreign body-associated intestinal pyogranulomas on histological examination. Three dogs recovered without complications, but the fourth showed signs of septic peritonitis four days after surgery and was euthanased at the owner's request. The other three dogs remained disease-free 12 to 42 months after surgery.

Laparoscopic removal of a large abdominal foreign body granuloma using single incision laparoscopic surgery (SILS) and extraction bag in a cheetah (Acinonyx jubatus)

“…GIT-related FBs are typically removed surgically (Kassem and others 2014) or less commonly endoscopically (Shin and others 2010, Baranidharan and others 2013). Moreover, after initial ingestion, GIT-related FB may penetrate through the muscular wall of GIT and migrate to their final location (Hunt and others 2004), where they may result in an extramural, omental pyogranulomatous (Papazoglou and others 2010, Nakata and others 2012) reaction or abscess (Spring 2011). A pyogenic granuloma, not caused by an FB, has also been reported in association with GIT in a dog (Nakata and others 2012).…”

Gastrointestinal Tract

“…113 However, no additional details on sonographic description were included. 114 Masses associated with the bowel have been seen with pyogranulomas secondary to foreign bodies, 115 hematomas, feline eosinophilic sclerosing fibroplasia, 60 fungal infection (histoplasmosis), 97 chronic granulomatous enteritis with normal cats or those diagnosed with inflammatory bowel disease. 47,48 Although in one case series of dogs with abdominal mast cell disease, which included mast cell disease in the liver, spleen, kidney, and abdominal lymph nodes, no abnormalities were identified in the gastrointestinal tract of any of the dogs.…”

Foreign Body Gastrotomy in an Adult Captive Cheetah, Acinonyx jubatus

“…The problem is also now increasingly being reported in wild animals (Eckermann-Ross, 2014;Omar, 2014;Squarre et al, 2015), parrots (Hoefer and Levitan, 2013), aquatic (Mousa et al, 2014) as well as marine animals (De Majo et al, 2016;Williams et al, 2013). It is normal for ingested foreign bodies to perforate the wall of the gastrointestinal tract and end up causing granulomatous lesions in the abdomen (Hoefer and Levitan, 2013;Papazoglou et al, 2010). Hartman et al (2015) have recently reported a thorn induced pyogranulomatous lesion in the abdomen of a cheetah.…”
