    Kurzfassung: To report intraoperative and major postoperative complications in dogs treated surgically for epiglottic retroversion (ER), compare the incidence of major postoperative complications between procedures, and report survival of surgically treated dogs. Study design Multi‐institutional retrospective study. Sample population Fifty dogs treated with 78 procedures. Methods Medical records of dogs diagnosed and surgically treated for ER from 2003 to 2017 at 11 institutions were reviewed. Complications were divided into intraoperative and major postoperative complications. Results Intraoperative complications occurred during 2 of 78 (2.6%) procedures. Thirty‐six major postoperative complications were documented in 22 dogs after 36 of 74 (48.7%) procedures. Postoperative complications occurred after 7 of 12 (58.3%) nonincisional epiglottopexy, 23 of 43 (53.5%) incisional epiglottopexy, 2 of 4 (50%) partial epiglottectomy, 2 of 12 (16.7%) subtotal epiglottectomy, and 2 of 3 (66.7%) other surgical procedures. Epiglottopexy failure was the most common major postoperative complication. The incidence of major postoperative complications did not differ between procedures ( P = .1239), although, when combined, epiglottopexy procedures (30/55) had a higher incidence of complications than epiglottectomy procedures (4/16; P = .048). Thirty (60%) dogs were alive at a median of 928 days (range, 114‐2805), 8 (16%) were lost to follow‐up after 411 days (range, 43‐1158), and 12 (24%) were dead/euthanized after 301.5 days (range, 3‐1212). Median survival time was not reached after a median of 716 days. Conclusion Although intraoperative complications were uncommon, major postoperative complications were common, especially after epiglottopexy procedures. Clinical significance Although surgical treatment of ER is associated with a high rate of major postoperative complications, especially epiglottopexy procedures, long‐term survival can be achieved.

    Kurzfassung: Canine intrarenal cystic lesions (ICLs) are infrequently reported in the veterinary literature. Several treatment options have been described including cyst fenestration (partial nephrectomy/deroofing) +/− omentalization, sclerotherapy using alcohol as a sclerosing agent, percutaneous cyst drainage (PCD), and ureteronephrectomy. Information regarding presenting clinical signs, physical examination findings, histologic diagnosis and outcomes of dogs with ICLs treated by different methods is limited. Medical records of 11 institutions were retrospectively reviewed to identify dogs that underwent PCD, sclerotherapy, surgical deroofing +/− omentalization, or ureteronephrectomy for management of ICLs from 2004 to 2021. Six weeks postoperative/post-procedural follow-up was required. Cases suspected to represent malignancy on preoperative imaging were excluded. The study objective was to provide information regarding perioperative characteristics, complications, and outcomes of dogs undergoing treatment of ICLs. Results Eighteen dogs were included, with 24 ICLs treated. Ten had bilateral. There were 15 males and 3 females, with crossbreeds predominating. PCD, sclerotherapy, deroofing and ureteronephrectomy were performed in 5 (5 ICLs treated), 7 (11 ICLs), 6 (6), and 7 (7) dogs, respectively, with 5 dogs undergoing 〉  1 treatment. Seven dogs experienced 8 complications, with requirement for additional intervention commonest. PCD, sclerotherapy and deroofing resulted in ICL resolution in 0/5, 3/11 and 3/6 treated ICLs, respectively. Histopathology identified renal cysts (RCs) in 7/13 dogs with histopathology available and neoplasia in 6/13 (4 malignant, 2 benign). Of 5 dogs diagnosed histopathologically with neoplasia, cytology of cystic fluid failed to identify neoplastic cells. Among 7 dogs with histologically confirmed RCs, 4 had concurrent ICLs in ipsilateral/contralateral kidney, compared with 2/6 dogs with histologically confirmed neoplasia. Conclusions Benign and neoplastic ICLs were approximately equally common and cystic fluid cytology failed to differentiate the 2. Among renal-sparing treatments, deroofing most commonly resulted in ICL resolution. Presence of concurrent ICLs in ipsilateral/contralateral kidney does not appear reliable in differentiating benign from malignant ICLs.

    Kurzfassung: To determine survival time and quality of life of dogs that developed postattenuation neurologic signs (PANS) after surgical treatment of a single congenital portosystemic shunt and survived at least 30 days and identify whether neurologic signs present at the time of discharge would resolve or reoccur. ANIMALS 50 client-owned dogs. PROCEDURES Medical records were retrospectively reviewed, and follow-up data relating to neurologic signs and seizure activity were obtained. Owners were asked to complete a questionnaire related to the presence of neurologic signs, including seizures, and their dog’s quality of life. RESULTS Thirty of the 50 (60%) dogs had postattenuation seizures with or without other nonseizure neurologic signs, and 20 (40%) had neurologic signs other than seizures. Neurologic signs had fully resolved by the time of discharge in 24 (48%) dogs. Signs resolved in 18 of the remaining 26 (69%) dogs that still had PANS other than seizures at the time of discharge. Seizures reoccurred in 15 of the 30 dogs that had postattenuation seizures. Twenty-seven of 33 (82%) owners graded their dog’s long-term ( 〉 30 days after surgery) quality-of-life as high. Forty-five (90%) dogs survived 〉 6 months. Most (29/43 [67%]) neurologic signs (other than seizures) present at the time of hospital discharge resolved. CLINICAL RELEVANCE Findings highlighted that survival times of 〉 6 months and a high QOL can be achieved in most dogs with PANS that survive at least 30 days. Most neurologic signs other than seizures resolved within 1 month postoperatively. Half of the dogs with postattenuation seizures had a reoccurrence.

    Kurzfassung: Maxillectomy is poorly described for the management of oral tumours in cats and is occasionally not recommended because of the high complication rate and sub‐optimal outcome reported in cats treated with mandibulectomy. The purpose of this study was to retrospectively evaluate the complications and oncologic outcome in cats treated with maxillectomy. Sixty cats were included in the study. Maxillectomy procedures included unilateral rostral (20.0%), bilateral rostral (23.3%), segmental (10.0%), caudal (20.0%) and total unilateral maxillectomy (26.7%). Intra‐operative and post‐operative complications were reported in 10 (16.7%) and 34 (56.7%) cats, respectively. The most common post‐operative complications were hyporexia (20.0%) and incisional dehiscence (20.0%). The median duration of hyporexia was 7 days. Benign tumours were diagnosed in 19 cats (31.7%) and malignant tumours in 41 cats (68.3%). Local recurrence and metastatic rates were 18.3% and 4.9%, respectively; the median progression‐free interval (PFI) was not reached. The disease‐related median survival time was not reached overall or for either benign or malignant tumours. The 1‐ and 2‐year survival rates were, respectively, 100% and 79% for cats with benign tumours, 89% and 89% for cats with malignant tumours, 94% and 94% for cats with fibrosarcomas, 83% and 83% for cats with squamous cell carcinomas, and 80% and 80% for cats with osteosarcomas. Poor prognostic factors included mitotic index for PFI, adjuvant chemotherapy for both PFI and survival time, and local recurrence for survival time. Maxillectomy is a viable treatment option for cats resulting in good local tumour control and long survival times.

    Kurzfassung: To determine and compare median sternotomy (MS) closure‐related complication rates using orthopedic wire or suture in dogs. Study design Multi‐institutional, retrospective observational study with treatment effect analysis. Animals 331 client‐owned dogs, of which 68 were excluded. Methods Medical records of dogs with MS were examined across nine referral centers (2004–2020). Signalment, weight, clinical presentation, surgical details, complications, and outcomes were recorded. Follow‐up was performed using patient records and email/telephone contact. Descriptive statistics, treatment effect analysis and logistic regression were performed. Results Median sternotomy closure was performed with wire in 115 dogs and suture in 148. Thirty‐seven dogs experienced closure‐related complications (14.1%), 20 in the wire group and 17 in the suture group. Twenty‐three were listed as mild, four as moderate and 10 as severe. Treatment effect analysis showed a mean of 2.3% reduction in closure‐related complications associated with using suture versus wire (95% CI: −9.1% to +4.5%). In multivariable logistic regression, the only factor associated with increased risk of closure‐related complications was dog size ( p  = .01). This effect was not modified by the type of closure used (interaction term: OR = 0.99 [95% CI: 0.96/1.01]). Conclusion The incidence of closure‐related complication after MS was low compared to previous reports. The likelihood of developing a closure‐related complication was equivalent between sutures and wires, independent of dog size, despite a higher proportion of complications seen in larger dogs (≥20 kg). Clinical significance Use of either orthopedic wire or suture appear to be an appropriate closure method for sternotomy in dogs of any size.

    Kurzfassung: A 6-month-old spayed female domestic shorthair cat presented for evaluation of suspected bite wounds over the right caudal thorax and left cranial flank. Thoracic radiographs identified a mild right-sided pneumothorax, a small volume of right-sided pleural effusion, with increased soft tissue opacity in the right cranial and middle lung lobes. Abdominal ultrasound identified a very small gall bladder and several small pockets of free peritoneal fluid. Cytological analysis of peritoneal fluid was consistent with a modified transudate. Following initial diagnostic investigations, yellow–orange fluid began to emanate from the right-sided thoracic wound. Biochemical analysis of this fluid was consistent with bile. Exploratory coeliotomy revealed a right-sided radial diaphragmatic tear, with herniation of the quadrate liver lobe and a portion of the gall bladder into the right pleural space. The gall bladder was bi-lobed and avulsion of a single herniated lobe resulted in leakage of bile into the right pleural cavity, without concurrent bile peritonitis (biloabdomen). The cat underwent total cholecystectomy and diaphragmatic defect repair and recovered uneventfully. Relevance and novel information To our knowledge, at the time of writing non-iatrogenic isolated bilothorax without concurrent biloabdomen has not been previously reported in the cat. This case highlights the importance of thorough assessment of cats with seemingly innocuous thoracic bite wounds. Despite the rarity of its occurrence, bilothorax should be considered a differential in cats with pleural effusion, even in the absence of bile peritonitis. We believe that the optimal treatment of cases of bilothorax is multifactorial and should be determined on a case-by-case basis.

    Kurzfassung: To identify prognostic factors for short‐term survival of dogs that experience seizures within 7 days after surgical correction of single congenital extrahepatic portosystemic shunts (cEHPSS). Study design Multi‐institutional retrospective study. Sample population Ninety‐three client‐owned dogs. Methods Medical records at 14 veterinary institutions were reviewed to identify dogs that underwent surgical attenuation of a single cEHPSS from January 1, 2005 through February 28, 2018 and experienced postattenuation seizures (PAS) within 7 days postoperatively. Logistic regression analysis was performed to identify factors associated with 1‐month survival. Factors investigated included participating institution, signalment, shunt morphology, concurrent/historical conditions, presence of preoperative neurologic signs, presence of preoperative seizures, aspects of preoperative medical management, surgical details including method and degree of shunt attenuation, type of PAS (focal only or generalized ± focal), drugs administered as part of the treatment of PAS, and development of complications during treatment of PAS. Results Thirty (32.3%) dogs survived to 30 days. Seventy‐six (81.7%) dogs experienced generalized PAS. Factors positively associated with short‐term survival included having a history of preoperative seizures ( P = .004) and development of focal PAS only ( P = .0003). Most nonsurvivors were humanely euthanized because of uncontrolled or recurrent seizures. Conclusion Dogs that experienced PAS that had a history of preoperative seizures and those that experienced focal PAS only had significantly improved short‐term survival. Clinical significance The results of this study provide information that will help in the counseling of owners who seek treatment for PAS after surgical correction of cEHPSS. © 2020 The American College of Veterinary Surgeons.

    Kurzfassung: A 9-year-old castrated male domestic shorthair cat (cat 1) and a 10-year-old castrated male Maine Coon cat (cat 2) were presented for recurrent feline lower urinary tract disease after receiving outpatient care from their primary veterinarians. CLINICAL FINDINGS Physical examination findings for both cats were initially within reference limits. After a short period of hospitalization, both cats developed peritoneal effusion; results of cytologic analysis of a sample of the fluid were consistent with septic peritonitis. During exploratory laparotomy, perforation of the pylorus or proximal portion of the duodenum secondary to ulceration was identified. TREATMENT AND OUTCOME Both cats underwent partial duodenectomy, partial gastrectomy (pylorectomy), and gastrojejunostomy (Billroth II procedure). The cats recovered from surgery and returned to a normal quality of life; however, each had mild episodes of anorexia but maintained a stable body weight. Cat 2 required additional surgery for trichobezoar removal 7 weeks later but recovered quickly. At 7 months after trichobezoar removal, cat 2 developed intermittent vomiting, but clinicopathologic, abdominal ultrasonographic, and upper gastrointestinal tract endoscopic findings were within reference limits. At 9 (cat 2) and 13 (cat 1) months after the Billroth II procedure, both cats were reported to be in good general health and without gastrointestinal signs. CLINICAL RELEVANCE In both cats, the Billroth II procedure was technically straightforward and associated with a full recovery and good medium- to long-term quality of life. A Billroth II procedure could be considered for treatment of cats with large mural lesions in the pyloroduodenal region.

    Kurzfassung: To report the incidence of postattenuation seizures (PAS) in dogs that underwent single congenital extrahepatic portosystemic shunt (cEHPSS) attenuation and to compare incidence of PAS in dogs that either did or did not receive prophylactic treatment with levetiracetam (LEV). Study design Multi‐institutional retrospective study. Population Nine hundred forty dogs. Methods Medical records were reviewed to identify dogs that underwent surgical attenuation of a single cEHPSS from January 2005 through July 2017 and developed PAS within 7 days postoperatively. Dogs were divided into 3 groups: no LEV (LEV−); LEV at ≥15 mg/kg every 8 hours for ≥24 hours preoperatively or a 60 mg/kg intravenous loading dose perioperatively, followed by ≥15 mg/kg every 8 hours postoperatively (LEV1); and LEV at  〈 15 mg/kg every 8 hours, for 〈 24 hours preoperatively, or continued at 〈 15 mg/kg every 8 hours postoperatively (LEV2). Results Seventy‐five (8.0%) dogs developed PAS. Incidence of PAS was 35 of 523 (6.7%), 21 of 188 (11.2%), and 19 of 228 (8.3%) in groups LEV‐, LEV1, and LEV2, respectively. This difference was not statistically significant ( P  = .14). No differences between groups of dogs that seized with respect to investigated variables were identified. Conclusion The overall incidence of PAS was low (8%). Prophylactic treatment with LEV according to the protocols that were investigated in our study was not associated with a reduced incidence of PAS. Clinical significance Prophylactic treatment with LEV does not afford protection against development of PAS. Surgically treated dogs should continue to be monitored closely during the first 7 days postoperatively for seizures.

    Kurzfassung: The development of postattenuation neurologic signs ( PANS ) is a poorly understood and potentially devastating complication after surgical attenuation of congenital portosystemic shunts in dogs. Postattenuation neurologic signs include seizures but also more subtle neurologic signs such as depression, behavioral changes, tremors, and twitching. They most commonly occur within 7 days postoperatively and are typically unrelated to hyperammonemia, hypoglycemia, or electrolyte disturbances. This narrative review summarizes the findings of 50 publications from 1988‐2020 that report occurrence of PANS . While most published reports included only dogs affected by postattenuation seizures ( PAS ), others included dogs with any form of PANS . Overall, PANS (including PAS ) affected 1.6%‐27.3% of dogs, whereas incidence of PAS ranged from 0%‐18.2%. The etiology of PANS remains unknown; however, several theories have been proposed. Risk factors include preoperative hepatic encephalopathy, increasing age, and possibly certain breeds and extrahepatic shunt morphology. There is increasing evidence that prophylactic antiepileptic drugs do not prevent PANS . Treatment is centered around controlling neurologic signs with antiepileptic drugs and providing supportive intensive care. The 30‐day survival rate in studies that included a minimum of four dogs affected by PANS was 0%‐100% (median, 50.0%) and 0%‐75.0% (median, 37.5%) for those with PAS . Mortality associated with PANS was typically related to occurrence of generalized seizure activity. Prognostic factors positively associated with short‐term survival included having a history of preoperative seizures and development of focal seizures only. If affected dogs survived to discharge, survival for several years was possible, and the majority of neurologic signs manifested as part of the phenomenon of PANS appeared to resolve.
