Results support the applicability of Fourier analysis for evaluation of force-time curves of GRFs. Fourier analysis can reveal subtle alterations of gait that might otherwise remain inapparent; however, further investigation is necessary before this method can be routinely applied for lameness detection in dogs.

A 7-year-old Jack Russell Terrier with a history of minor trauma was presented for lameness of the left forelimb. Radiography and computed tomography demonstrated a localized radioulnar osteolytic lesion with cortical bone loss and enthesiophytes. Based on results of diagnostic imaging and histopathological examination, the final diagnosis was radioulnar ischemic necrosis (RUIN), complicated by pathologic fracture. A rare disorder of unknown etiology, RUIN may be secondary to tearing of the interosseous ligament and potential ischemia. It should be differentiated from neoplastic or fungal disease. To the authors´ knowledge, this is the first canine case report describing RUIN.

The aim of this retrospective study and owner survey was to record the postoperative complication rate, pain score and owners’ satisfaction rates of single portal laparoscopic ovariectomy in dogs using an operating laparoscope and to compare our results with data in the veterinary literature on other laparoscopic methods. Therefore, the medical records of all bitches that were spayed using a laparoscopic single port ovariectomy with an operating laparoscope between November 2007 and November 2014 were reviewed. A minimum follow-up period of 12 months was required for study inclusion. One hundred and thirty two adult, healthy, femal dogs were included in our study. The information collected included breed, bodyweight, age at ovariectomy and postoperative complications detected during follow-up 9–14 days after surgery. Furthermore, an electronic questionnaire was implemented, and the owners of the dogs were asked to report on long-term complications and to retrospectively evaluate postoperative pain and overall satisfaction. Sixty-two different and mixed breed dogs with weights ranging from 1.9 to 50 kg and ages ranging from 0.5 to 10.8 years were included. Short-term complications were detected in 21 out of 132 cases, mostly at the surgical site (15.9 per cent). According to our questionnaire (n=65), 10 dogs developed urinary incontinence categorised as a major complication (15.4 per cent). The owner’s evaluated pain score was less than 300 on a 1000-unit visual analogue scale for 56 out of 65 dogs (86.2 per cent) and less than 500 in 63 dogs (96.9 per cent). The dog owners’ satisfaction rate was 95.3 per cent (87.5 per cent evaluated the surgery as excellent and 7.8 per cent as good). Altogether, our study suggests that single port access using an operating laparoscope for ovariectomy has minor complication rates comparable to other laparoscopic techniques but has the advantages of a low postoperative pain level as evaluated by the owner and a very high owner’s satisfaction rate.

Objectives The aim of this study was to report complications, as well as short- and long-term clinical outcomes of cats suffering from surgically reduced intussusception with and without enteroplication. Methods Medical records of cats presented at our institution with intussusception between 2001 and 2016 were reviewed. The following data were retrieved: signalment; history; physical examination; diagnostic imaging, surgical and histological findings; and outcomes. Animals were grouped as with or without enteroplication. Duration of surgery, survival, complication and recurrence rates, duration of hospitalisation, and short- and long-term outcomes were compared. Results Cats with intussusception presented with unspecific type and duration of clinical signs. Male or male castrated cats and Maine Coons were over-represented in both groups. Enteroplication was performed in 48% (10/21) of the cats. Cats in the enteroplication group were significantly younger than those in the non-enteroplication group ( P = 0.023). Duration of surgery, time of hospitalisation, complication rate and outcomes did not differ between the two groups. Two complications in the short term and one complication in the long term were possibly associated with enteroplication. A recurrence of intussusception was seen in 2/17 cats approximately 12 months after initial surgery, both previously treated with enteroplication. Conclusions and relevance Although the number of cases was limited, our results suggest that enteroplication should be cautiously performed in cats with intussusception as it may be associated with major complications in the short and long term, and its efficacy remains unclear. Based on this study, the need for enteroplication in cats following a correction of intussusception could be questioned.

A 5-year-old intact female Chihuahua was transferred to our hospital for attenuation of a portosystemic shunt. The attenuation was done by means of cellophane banding and a routine liver biopsy was taken. Postoperatively, the dog developed haemoabdomen and the haematocrit dropped to 11 per cent. Relaparotomy revealed an acute haemorrhage from the biopsy site and partial liver lobectomy was performed to control bleeding. Despite all attempts at treatment, the dog developed serious metabolic and respiratory derangements and eventually died after an episode of respiratory arrest. With this report, the authors want to raise awareness of this potentially fatal complication and motivate the readers to weigh the benefit of additional information against the risk a ‘simple’ liver biopsy could entail in animals undergoing portosystemic shunt attenuation.
