Ultrasonographic and computed tomographic features of a true gastro-gastric intussusception with concurrent foreign bodies in a dog.

A 2-year-old intact male Cane Corso dog was presented for acute weakness, vomiting, and diarrhea. Abdominal ultrasound revealed the stomach had severe wall edema and a target appearance. Computed tomography was consistent with a gastro-gastric intussusception and concurrent mineral-like gastric foreign bodies. After reduction of the intussusception, bilateral incisional gastropexy was performed to prevent recurrence. True gastrogastric intussusception is a rare condition and should be considered if the stomach has severe wall edema with a target sign on abdominal ultrasound. Computed tomography was useful to confirm this rare diagnosis and screen the entire abdomen for concurrent lesions. Key clinical message: This case highlights the usefulness of a CT examination to confirm this rare diagnosis, to determine the position of gastric compartments, and to detect potential concurrent lesions prior to surgery.

Caractéristiques échographiques et tomodensitométriques d'une véritable intussusception gastrogastrique avec corps étrangers concomitants chez un chien. Un chien Cane Corso mâle intact de 2 ans a été présenté pour faiblesse aiguë, vomissements et diarrhée. L'échographie abdominale a révélé que l'estomac présentait un ædème sévère de la paroi et une apparence de cible. La tomodensitométrie était compatible avec une intussusception gastro-gastrique et des corps étrangers gastriques de type minéral concomitants. Après réduction de l'intussusception, une gastropexie incisionnelle bilatérale a été réalisée pour prévenir les récidives. L'intussusception gastro-gastrique vraie est une affection rare et doit être envisagée si l'estomac présente un ædème sévère de la paroi avec un signe de cible à l'échographie abdominale. La tomodensitométrie a été utile pour confirmer ce diagnostic rare et d'examiner tout l'abdomen à la recherche de lésions concomitantes.Message clinique clé :Ce cas met en évidence l'utilité d'un examen CT pour confirmer ce diagnostic rare, pour déterminer la position des compartiments gastriques et pour détecter d'éventuelles lésions concomitantes avant la chirurgie.(Traduit par Dr Serge Messier).

Effect of Intravenous Morphine Injection on Neurological Examination of Dogs With Thoracolumbar Intervertebral Disk Extrusion.

Objectives: We aimed to determine the effect of intravenous morphine injection on the modified Frankel scores of dogs with thoracolumbar intervertebral disk extrusion (IVDE). Methods: This was a prospective, blinded, randomized, and placebo-controlled study. We included dogs with a presumptive diagnosis of thoracolumbar IVDE that did not undergo analgesic, anti-inflammatory, or sedative treatment within the last 12 h. A neurological examination was performed and the deficits were graded using the modified Frankel score (MFS). Subsequently, each dog was randomly allocated to receive an intravenous injection of either morphine or placebo. After 30 min, the dogs were re-evaluated by the same veterinary officer who was blinded to the contents of the injections. Dogs were included in the study if IVDE was ultimately confirmed by surgery within one week of initial presentation. Results: Among the 79 dogs initially enrolled, 62 dogs met the inclusion criteria. Among them, thirty-two dogs received intravenous morphine injections and there was no difference between the pre- and post-injection modified Frankel scores. Thirty dogs received an intravenous placebo injection. One dog had a worsening of the MFS by one grade in the post-injection examination. Clinical Significance: In dogs with thoracolumbar intervertebral disk extrusion, an intravenous injection of morphine does not affect the modified Frankel score after 30 min compared with the pre-injection value. These findings support the use of an analgesic morphine dose if the neurological examination can be performed 30 min or later after the injection.

Infection and extrusion of a subcutaneous access port in a cat: a long-term postoperative complication of a subcutaneous ureteral bypass device.

CASE SUMMARY: A 5-year-old domestic shorthair neutered female cat was presented for a wound in the region of the subcutaneous ureteral bypass shunting port with externalisation of the device, 2 years after its initial positioning. The cat had had positive urine bacterial cultures over the previous year and a half without any clinical signs of urinary tract infection. Bacterial cultures of urine and the wound revealed the same bacteria, suggesting a complication caused by infected urine from the implanted system. The wound was successfully treated with surgery and at the time of writing, 3 months later, the cat is healthy with no evidence of recurrence. RELEVANCE AND NOVEL INFORMATION: To our knowledge, this is the first report of a subcutaneous ureteral bypass shunting port extrusion as a long-term major complication of the bacterial infection of the device.
