An adult Standard Poodle was presented with gastric dilation and volvulus (GDV). An emergency laparotomy was performed, during which the stomach was derotated and an incisional gastropexy was performed. The dog recovered uneventfully from surgery and was stable for two days. Three days postoperatively, his condition declined markedly. Evidence of peritonitis was found on abdominal ultrasound, with no clearly identified underlying cause. The dog was euthanased and underwent gross postmortem examination. A small intestinal volvulus and macroscopic evidence of strangulation of a section of colon transversum with intestinal perforation was found. There were no lesions identified associated with the stomach or gastropexy site. This case report discusses possible reasons for the development of the intestinal volvulus and the strangulation and rupture of the colon in a dog after GDV surgery.

“…The authors suggest that the “whirl sign” may be used to aid in the diagnosis of canine colonic torsion. However, a recent case report described the CT findings in a dog with colonic torsion and entrapment due to an omental rent and included segmental distension, displacement and focal narrowing of the colon, and an approximate 180° anticlockwise axial rotation of the descending colon . A “whirl sign” and mesenteric vascular distension were not identified on CT and the torsion was not recognized during surgery .…”

“…The use of CT was preferred in our dogs due to their large size and the ease of image acquisition compared to other modalities such as radiography or ultrasound. 18,19 It also offers additional advantages over radiography such as superior contrast resolution without superimposition. In addition, CT may help diagnose potential sequel to colonic torsion that cannot be identified using radiography alone.…”

Colonic torsion is a life‐threatening condition that results in colonic ischemia, necrosis, perforation, sepsis, and eventual death. The aim of this multicenter, retrospective case series study was to describe the CT findings in dogs with surgically confirmed colonic torsion. Medical records were searched for dogs with surgically confirmed colonic torsion following abdominal CT. Five dogs met the inclusion criteria. Three had a history of chronic intermittent diarrhea prior to presentation. Two dogs presented with acute vomiting, diarrhea, and abdominal pain and one dog presented with acute vomiting and lethargy. Computed tomographic findings in all dogs with surgically confirmed colonic torsion include: “whirl sign,” displacement and distension of the cecum and colon, focal narrowing of the colon, and distension of the mesenteric vasculature in all dogs (5/5); streaky peritoneal fat and peritoneal effusion (4/5), pneumatosis coli (2/5), small intestinal distension (2/5), portal vein thrombosis (1/5), and reduced colonic wall contrast enhancement (1/5). In all dogs (5/5), the torsion site was the descending colon and demonstrated an anticlockwise rotation. At surgery, three of the five dogs had a partial colonic torsion with hyperemia at the site of obstruction and two of the five dogs had a complete torsion with marked necrosis of the colonic wall. Displacement of the colon and cecum, segmental distension and focal narrowing of the colon, the presence of a “whirl sign” and distension of the mesenteric vasculature are CT findings highly suggestive of colonic torsion.
