Evaluation of video tape and a simulator for instruction of basic surgical skills.

Twenty first-year veterinary students with no prior participatory experience in surgery were randomly paired and assigned into two study groups. Ten students (group V) viewed a hemostatic technique video tape until they thought they could competently perform and assist in performing a hand-tied ligature on a blood vessel in a live animal. Ten students (group VS) wer also given a simulator for technique practice. Paired students were video recorded and blindly evaluated on their ability to perform and assist proper ligation of a bleeding vessel. Inexpensive hemostasis models were very helpful for teaching students essential surgeon and assistant skills involved in hand-tied ligature placement. Students who practiced with simulators performed significantly better as surgeon and assistant, and in total psychomotor skill evaluation, then students watching the video only. Students using simulators performed ligation with significantly more accuracy and tended to be more expeditious at this task. Further training is needed for students to acquire skills necessary for efficient bleeding vessel exposure and isolation.

Mouse cardiac surgery: comprehensive techniques for the generation of mouse models of human diseases and their application for genomic studies.

Mouse models mimicking human diseases are important tools in trying to understand the underlying mechanisms of many disease states. Several surgical models have been described that mimic human myocardial infarction (MI) and pressure-overload-induced cardiac hypertrophy. However, there are very few detailed descriptions for performing these surgical techniques in mice. Consequently, the number of laboratories that are proficient in performing cardiac surgical procedures in mice has been limited. Microarray technologies measure the expression of thousands of genes simultaneously, allowing for the identification of genes and pathways that may potentially be involved in the disease process. The statistical analysis of microarray experiments is highly influenced by the amount of variability in the experiment. To keep the number of required independent biological replicates and the associated costs of the study to a minimum, it is critical to minimize experimental variability by optimizing the surgical procedures. The aim of this publication was to provide a detailed description of techniques required to perform mouse cardiac surgery, such that these models can be utilized for genomic studies. A description of three major surgical procedures has been provided: 1) aortic constriction, 2) pulmonary artery banding, 3) MI (including ischemia-reperfusion). Emphasis has been placed on technical procedures with the inclusion of thorough descriptions of all equipment and devices employed in surgery, as well as the application of such techniques for expression profiling studies. The cardiac surgical techniques described have been, and will continue to be, important for elucidating the molecular mechanisms of cardiac hypertrophy and failure with high-throughput technology.

The veterinary technician's role in laser surgery.

The use of surgical lasers in veterinary practice has grown significantly since 1996. Many veterinarians have studied and implemented the basic physics and tissue didactics required to successfully incorporate a surgical laser program into their practice. The support role of the veterinary technician is crucial to ensuring an efficient, safe, and successful outcome of any surgical laser procedure. The technician's role may include practice management duties, client communication, and laser safety officer duties. Although there are a variety of lasers, the most common types used in veterinary practice are carbon dioxide (CO2) and diode. This article presents an overview of the veterinary technician's role as a key support person in ensuring a safe and positive outcome in the implementation of CO2 and diode lasers in a veterinary practice.

Gastrinoma: a retrospective study of four cases (1985-1995).

Islet-cell tumors of the pancreas, such as gastrinoma, are rare in veterinary medicine. Patients with gastrinoma or Zollinger-Ellison syndrome have elevated serum gastrin levels which ultimately cause gastrointestinal ulcerations. Due to their small size, gastrinomas are a challenge to localize prior to surgery. In veterinary medicine, exploratory surgery with biopsy for histopathology confirms the diagnosis of gastrinoma. This is a retrospective study of four dogs with gastrinoma.

[Possibilities and status of heart surgery in dogs].

Before use of cardiovascular surgical techniques and procedures in humans, many experiments, e.g., hypothermic circulatory arrest and cardiopulmonary bypass using the heart-lung machine, have been performed in the dog. As a consequence experimental canine cardiovascular surgery is highly developed. This has not resulted in the routine performance of open heart surgery in veterinary medicine, probably because of the high costs. Cardiovascular surgery in the dog is generally limited to interventions not depending on hypothermic circulatory arrest or cardiopulmonary bypass. The clinical cardiovascular surgery in dogs can be divided into routine and more specialized interventions. The first category includes correction of peritoneopericardial diaphragmatic hernia, pericardial fenestration in dogs with pericardial effusion, treatment of persistent right aortic arch, and patent ductus closure. The specialized interventions include dilation of pulmonic and aortic stenoses and pacemaker implantation. The diagnosis and surgical treatment of such diseases is described. New developments in cardiovascular surgical treatment that can be expected include catheter techniques for occlusion of shunts and dilations using balloons, because the financial costs of these procedures are not prohibitive.
