Topic:Minimally Invasive Surgery
Minimally invasive surgery (MIS) in horses refers to surgical techniques that limit the size and number of incisions needed to perform procedures. These techniques often involve the use of specialized equipment such as endoscopes, cameras, and instruments designed for precision. MIS aims to reduce tissue trauma, potentially leading to shorter recovery times and decreased post-operative discomfort compared to traditional surgical methods. Common minimally invasive procedures in equine medicine include arthroscopy, laparoscopy, and thoracoscopy, which are used for diagnostic and therapeutic purposes. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, applications, and outcomes of minimally invasive surgery in equine practice.
Use of stapling instruments to aid in the removal of ovarian tumours in mares. Ovarian granulosa theca cell tumours were removed surgically in 10 mares. Stapling instruments were used to facilitate haemostasis of the ovarian pedicle in five out of 10 cases and as a sole method of haemostasis in the remaining five cases. Postoperative haemorrhage from the ovarian pedicle was suspected in only one case. All cases survived long term follow-up from six months to four years. Results from this series of cases indicate that stapling instruments provide a rapid, easy and efficient means of ligating ovarian pedicles when performing ovariectomy in the mare.
Diagonal paramedian approach for removal of ovarian tumors in the mare. A diagonal paramedian approach to the abdomen was used for unilateral ovariectomy in 15 mares. In each case, surgery was performed for removal of a granulosa cell tumor. All horses recovered from surgery with minimal complications. Surgical exposure of the affected ovary was adequate to allow exteriorization and ligation. Other advantages of this approach were ease of closure and lack of postsurgical complications.
A technique for elective splenectomy of equidae using a transthoracic approach. Splenectomy was performed electively on 80 ponies, horses, and donkeys for preparation in collecting Babesia antigens. Access to the abdomen was by resection of the sixteenth left rib and incision of the diaphragm. The technique afforded good exposure of the splenic vessels and attachments. Closure was facilitated by preservation of the periosteum of the resected rib. Difficulty was encountered both in surgical technique and postoperative complications in obese animals. The transthoracic approach was found to be a useful technique for equine splenectomy.
Technique for arthroscopic repair of third carpal bone slab fractures in horses. A technique involving internal fixation guided by arthroscopy was used to repair third carpal slab fractures in 23 horses. The technique allowed good reduction and compression of the fractures, with minimal surgical trauma. Ten of 17 horses with a 6-month or longer follow-up have returned to race successfully.
Neodymium (Nd):YAG laser surgery in the equine larynx: a pilot study. Laryngeal surgery in the equine is customarily and routinely performed by means of a ventral laryngotomy incision. Such procedures are usually performed under deep general anesthesia with the horse in dorsal recumbency. The objective of this work was to determine the efficacy of an endoscopic approach coupled to a Nd:YAG laser fiber in performing arytenoidectomy. Arytenoidectomy is commonly indicated in the treatment of arytenoid chondritis and in the failure of prosthetic implantation for left laryngeal hemiplegia. This preliminary study was undertaken to determine the feasibility of the endo...
Experiences in diagnostic and surgical arthroscopy in the horse. This paper reviews the current status of diagnostic and surgical arthroscopy in the horse. Arthroscopy has been used as a diagnostic aid since 1974 and is useful for evaluation of abnormalities in synovial membrane and articular cartilage. Surgical arthroscopy is a more recent advance that has replaced conventional arthrotomy in 90 per cent of the author's cases. Clinical conditions currently being treated using arthroscopic techniques rather than arthrotomy include all chip fractures in the carpus, chip fractures of the first phalanx, chronic proliferative synovitis in the fetlock and osteoch...
Surgical correction of deviated nasal septum and premaxilla in a colt. A 6-month-old Appaloosa colt had a deviation of the premaxilla and nasal septum as well as a dorsal hump of the nasal bone and maxillomandibular malocclusion. Two surgical procedures were performed 12 weeks apart to correct these anomalies. An intraoral approach and autogenous rib graft were used to correct the malocclusion and deviation of the premaxilla. Osteotomy of the nasal bone and removal of the nasal septum were performed to help correct the deviation and to facilitate free air passage through the nares.
Pelviscopy in the mare. A method of endoscopic examination of the internal genital (pelvic) organs of the mare is described. Special emphasis is placed on the induction of artificial pneumoperitoneum and the installation of an endoscopic peritoneal fistula device for prolonged observation. The potential of pelviscopy in the mare as a diagnostic aid, a new device for research in equine reproduction and as an auxillary aid to teaching is discussed.
Percutaneous lung biopsy in the horse. Percutaneous lung biopsies with a cutting needle (Vim Tru Cut) were obtained from 20 horses. The procedure was performed in standing horses under a local anesthesia without sedation. All lung tissue specimens were suitable for histologic examinations and contained both pulmonary parenchyma and large airways. The only complication was hemoptysis in 2 (10%) horses which required no therapy. All horses were subsequently killed, and no gross abnormalities were present at the biopsy site.
Simple surgical approach to iliac arteries of the horse for blood flow measurement. Bood flow was measured in the external iliac artery of the
horse during standing and walking. The Franklin Doppler
blood flow-telemetry system was used in this study. The transducer was placed on the external iliac artery using a retroperitoneal approach through the vaginal wall.
A Simplified Approach to Splenectomy in the Horse. THE NEED FOR splenectomized horses in piroplasmosis research prompted this study. Quinlan et at.1 described in detail problems encountered using the paralumbar approach to splenectomy. Gaining easy access to the splenic ligaments and vessels was difficult; for this reason the type and age of horse which could be used were limited. The purpose of this report is to present technic by which horses of varying size, age, and conformation can be splenectomized with minimum of stress on the patient and on the surgeon.
