    Abstract: To describe a technique for treating pyometra in dogs using a 3‐portal laparoscopic‐assisted ovariohysterectomy (LAOVH) and evaluate outcome. Study Design Retrospective case series. Animals Dogs (n = 12). Methods Dogs with open or closed‐cervix pyometra with moderately sized (1–4 cm) uterine horn diameters based on preoperative ultrasonography and no evidence of perforation were included in the study. A 3‐portal technique for LAOVH was used. A wound retraction device was inserted into the caudal portal after enlargement of the incision to 3–4 cm to simplify removal of the uterus with minimal tension. Results Twelve dogs (median weight, 23.3 kg; range, 2.1–46.0 kg) met the inclusion criteria. Median uterine diameter was 3.0 cm (range, 1.2–4.0 cm). Median surgical time for LAOVH was 107 minutes (range, 82–120 minutes). Complications included mild hemorrhage from the uterine vessels in 1 dog during uterine removal through the wound retraction device and intra‐abdominal uterine rupture in 1 dog which necessitated conversion to an open approach. All dogs recovered from surgery and were discharged. Conclusions LAOVH can be used for treatment of select cases of canine pyometra. Careful case selection is mandatory to improve success and minimize conversion to an open approach. Gentle handling of the reproductive organs is imperative to avoid iatrogenic uterine rupture.

    Abstract: Objective —To describe the technique and evaluate the outcome of laparoscopic treatment of ovarian remnant syndrome (ORS) in dogs and cats. Design —Retrospective case series. Animals —7 client-owned dogs and cats. Procedures —Medical records of dogs and cats with ORS that were treated laparoscopically at 3 large veterinary teaching hospitals were reviewed. Laparoscopic ovarian remnant resection was performed by means of either a 3-port or single-port technique with the patient in dorsal recumbency. The area caudal to both kidneys was thoroughly inspected for evidence of ovarian tissue by tilting the patient laterally. Any ovarian remnant tissue in these areas was resected with a bipolar vessel sealer. Results —5 female dogs and 2 female cats that had previously undergone ovariectomy or ovariohysterectomy were included in the study. Six procedures were performed with a standard 3-port technique, and 1 was performed with a single-port technique. Median surgery time was 90 minutes (range, 50 to 150 minutes). No patient required conversion to laparotomy. Six of the 7 patients had complete resolution of clinical signs after surgery. One patient underwent laparotomy 7 weeks after surgery for management of stump pyometra, but no further ovarian tissue was detected. Conclusions and Clinical Relevance —Laparoscopic management of ORS in this cohort of dogs and cats was associated with minimal morbidity. Laparoscopic treatment of ORS in dogs and cats may be recommended for appropriately selected patients.

    Abstract: OBJECTIVE To describe surgical techniques and perioperative management of dogs with von Willebrand disease (VWD) or factor VII (FVII) deficiency undergoing laparoscopic ovariohysterectomy or ovariectomy and evaluate outcomes. DESIGN Retrospective case series. ANIMALS 20 client-owned dogs with VWD (n = 16) or FVII deficiency (4). PROCEDURES Dogs with VWD or FVII deficiency that underwent laparoscopic ovariohysterectomy or ovariectomy between 2012 and 2014 were retrospectively identified via a multi-institutional review of medical records. RESULTS Median expression of von Willebrand factor was 19% (interquartile range, 18% to 30%). All 16 dogs with VWD were Doberman Pinschers, and all were pretreated with desmopressin; 4 also received cryoprecipitate. One of 4 dogs with FVII deficiency received plasma preoperatively, and 1 was treated with desmopressin; 2 dogs received no preoperative treatment. Laparoscopic ovariectomy was performed in 9 dogs with VWD and 2 dogs with FVII deficiency, laparoscopic ovariectomy with gastropexy was performed in 6 dogs with VWD and 1 dog with FVII deficiency, and laparoscopic-assisted ovariohysterectomy was performed in 1 dog with VWD and 1 dog with FVII deficiency. Iatrogenic splenic laceration requiring conversion to laparotomy occurred during trocar insertion in 1 dog with VWD. No postoperative complications, including signs of hemorrhage, were reported for any dogs. CONCLUSIONS AND CLINICAL RELEVANCE Laparoscopic ovariohysterectomy or ovariectomy in dogs with VWD or FVII deficiency pretreated with desmopressin, cryoprecipitate, or plasma transfusions were not associated with clinical signs of hemorrhage, suggesting that minimally invasive ovariohysterectomy or ovariectomy may be considered in female dogs affected with these coagulopathies.

    In: Veterinary Surgery, Wiley, Vol. 45, No. 6 ( 2016-08), p. 775-781
    Abstract: Objective: To describe indications for, and outcomes after, pneumonectomy in dogs and cats, including assessment of immediate postoperative respiratory function in comparison to dogs undergoing single lung lobectomy. Study Design: Retrospective case series. Animals: Dogs (n=16) and cats (n=7) with naturally occurring pulmonary disease. Methods: Medical records (1990–2014) of dogs and cats undergoing right or left pneumonectomy were reviewed. Data retrieved included signalment, history, preoperative diagnostics, operative descriptions, postoperative data including respiratory function, and postdischarge outcomes. For respiratory function comparisons, medical records of dogs having undergone a single lung lobectomy via median sternotomy (n=15) or intercostal thoracotomy (n=15) were reviewed. Results: Twenty‐three cases (16 dogs, 7 cats) were included. Pneumonectomy was performed for congenital (1 dog, 1 cat), neoplastic (8 dogs, 1 cat), and infectious (7 dogs, 5 cats) disease. Postoperative aspiration pneumonia occurred in 2 dogs; 15 of 16 dogs (94%) and 6/7 cats (86%) survived to hospital discharge. After pneumonectomy, dogs had a significantly higher postoperative PaO 2 on 21% oxygen ( P =.033) and lower postoperative A‐a gradient ( P =.004) compared to dogs undergoing single lung lobectomy. Survival times (right‐censored at last follow‐up) for dogs ranged from 2 days to 7 years (estimated median=1,868 days) and for cats from 1–585 days. Conclusion: Dogs and cats have acceptable respiratory function immediately postoperatively and most have protracted long‐term survival after pneumonectomy for a variety of pulmonary diseases.

    Abstract: To describe surgical technique, biopsy sample quality, and short-term outcome of minimally invasive small intestinal exploration and targeted abdominal organ biopsy (MISIETB) with use of a wound retraction device (WRD) in dogs. ANIMALS 27 client-owned dogs that underwent MISIETB with a WRD at 1 of 4 academic veterinary hospitals between January 1, 2010, and May 1, 2017. PROCEDURES Medical records were retrospectively reviewed, and data collected included signalment; medical history; findings from physical, ultrasonographic, laparoscopic, cytologic, and histologic evaluations; surgical indications, procedures, duration, and complications; and short-term (14-day) outcomes. The Shapiro-Wilk test was used to evaluate the normality of continuous variables, and descriptive statistics were calculated for numeric variables. RESULTS Laparoscopic exploration was performed through a multicannulated single port (n = 18), multiple ports (5), or a single 6-mm cannula (4). Median length of the incision for WRD placement was 4 cm (interquartile [25th to 75th percentile] range, 3 to 6 cm). All biopsy samples obtained had sufficient diagnostic quality. The 2 most common histologic diagnoses were lymphoplasmacytic enteritis (n = 14) and intestinal lymphoma (5). Twenty-five of 27 (93%) dogs survived to hospital discharge, and 3 (12%) dogs had postsurgical abnormalities unrelated to surgical technique. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that MISIETB with WRD was an effective method for obtaining diagnostic biopsy samples of the stomach, small intestine, pancreas, liver, and mesenteric lymph nodes in dogs. Prospective comparison between MISIETB with WRD and traditional laparotomy for abdominal organ biopsy in dogs is warranted.

    Abstract: OBJECTIVE To characterize clinical findings, surgical procedures, complications, and outcomes in dogs undergoing extirpation of masses from the cranial mediastinum via video-assisted thoracic surgery (VATS) and establish preliminary guidelines for case selection when considering VATS for thymectomy in dogs. DESIGN Retrospective case series. ANIMALS 18 client-owned dogs that underwent extirpation of a cranial mediastinal mass by means of VATS at 5 academic referral hospitals from 2009 through 2014. PROCEDURES Medical records were reviewed and data extracted regarding signalment, clinical signs, physical examination findings, diagnostic imaging results, surgical approach and duration, cytologic and histologic examination results, complications, outcome, and cause of death, when applicable. RESULTS 16 dogs had a thymoma, 1 had thymic anaplastic carcinoma, and 1 had hemangiosarcoma. Seven had both megaesophagus and myasthenia gravis. Median approximate tumor volume was 113.1 cm 3 (interquartile range, 33.5 to 313.3 cm 3 ). Median duration of VATS was 117.5 minutes (interquartile range, 91.5 to 136.3 minutes). Conversion to an open thoracic surgical procedure was required for 2 dogs, 1 of which died during surgery. Median survival time following VATS for dogs with thymoma and concurrent myasthenia gravis and megaesophagus was 20 days. Dogs with thymoma without paraneoplastic syndrome survived for ≥ 60 days, and none of these dogs died of disease-related causes. CONCLUSIONS AND CLINICAL RELEVANCE VATS appeared to be an acceptable approach for extirpation of masses from the cranial mediastinum in dogs under certain conditions. Dogs with myasthenia gravis and megaesophagus had a poor postoperative outcome.

    Abstract: To report the morbidity and mortality associated with adrenalectomy with cavotomy for resection of invasive adrenal neoplasms in dogs and evaluate risk factors for perioperative outcomes. Study design Retrospective study. Animals Forty‐five client‐owned dogs. Methods Dogs that underwent open adrenalectomy with cavotomy for resection of adrenal masses with tumor thrombus extending into the vena cava were included. Clinicopathologic data were harvested from medical records. Selected clinical, imaging, and operative variables were statistically evaluated as risk factors for packed red blood cell transfusion, nephrectomy, perioperative death, and overall survival. Results Thirty‐six of 45 masses were pheochromocytomas, 7 were adrenocortical carcinomas, and 2 were unknown type. Caval thrombus terminated prehepatically in 21 of 45 dogs and extended beyond the porta hepatis but terminated prediaphragmatically (intrahepatic prediaphragmatic location) in 15 dogs and thrombi extended postdiaphragmatically in 5 dogs. Thirty‐four (76%) dogs were discharged from the hospital, and 11 (24%) dogs died or were euthanized prior to discharge. Median overall survival time for all 45 dogs was 547 days (95%CI 146–710). Bodyweight, tumor type, and size and extent of caval thrombus did not affect survival to discharge, but postdiaphragmatic (rather than prediaphragmatic) thrombus termination was associated with a greater risk of death. Conclusion Long‐term survival was common in dogs that survived the perioperative period. Postdiaphragmatic thrombus extension affected the prognosis for overall survival. Clinical significance Findings of this study help to stratify operative risk in dogs with adrenal neoplasia and caval invasion.
