动物腹腔镜技术的应用研究进展 总被引：5，自引：0，他引：5
在国外,腹腔镜技术已经用于动物疾病诊疗、活体检查、组织取样、卵巢卵泡发育情况及局部解剖观察,以及辅助进行动物的人工授精、胚胎移植等;还可以进行犬、猫等动物的子宫、卵巢切除术、牛皱胃左方变位整复术等手术操作。在国内,动物腹腔镜技术起步较晚,目前仅局限于胚胎移植或人工授精过程中对卵巢卵泡发育情况的观察,或进行简单的操作。文章阐明了腹腔镜技术创伤小、恢复快、对机体影响小等优点,分析了目前动物腹腔镜技术相对滞后的原因,指明了该技术在动物上的应用前景。 相似文献

电针麻醉在外科手术中,特别是在胸腹腔手术中的应用,具有效果确实、麻醉副作用小,操作简单易行、术后恢复快、由于手术引起的感染少等优点。但是,电针麻醉进行腹腔手术中的内脏牵拉反应一直是没有得到彻底解决的问题,也是腹腔手术顺利进行的一大障碍。我们采用耳根穴和关元俞穴电针麻醉,发现对内脏牵拉反应有较强抑制作用。对此,我们进行了动物试验研究。一、实验动物家兔。 相似文献

Laparoscopic Repair of a Bladder Rupture in a Foal 总被引：1，自引：0，他引：1
RYLAND B. EDWARDS III DVM NORM G. DUCHARME DVM MSc Diplomate ACVS RICHARD P. HACKETT DVM MS Diplomate ACVS 《Veterinary surgery : VS》1995,24(1):60-63
Ruptured bladder was diagnosed in a 90-day-old Thoroughbred colt that had suffered a open, comminuted tibial fracture 2 days earlier. The bladder rupture was identified by laparoscopic examination of the abdomen and was repaired using a laparoscopic stapling instrument. This technique provided good visualization and allowed repair of the rupture with minimal intervention. Ten months after surgery, the foal was admitted to a referral surgical practice because of colic and stanguria. A urinary calculus was removed from the penile urethra by urethrotomy. Laparoscopic repair of the bladder with nonabsorbable staples may be contraindicated because of possible urolith formation. 相似文献

Laparoscopic artificial insemination technique (LAI) is described to overcome reduced fertility problems in sheep artificial insemination (AI) programmes with frozen semen. Later on, this technology was modified for endangered non-domestic cats to deposit low quality or reduced number of sperm cells hardly obtained by electro-ejaculation into the oviduct. This technique by passes the complex structure of cervix and efficiently transfers the sperm cells to the point of fertilization. In recent years, rabbits are becoming popular transgenic animal models producing various therapeutic and commercial products, as well as being experimental animals for disease models. The worldwide transportation of frozen semen and re-establishment of transgenic lines using AI technology has become a common practice. Therefore, this study was designed to describe a laparoscopic intrauterine insemination technique, which might assist in conceiving the animals with limited number of sperm cells. The female rabbits were laparoscopically (n = 22) or vaginally (n = 13) inseminated with frozen–thawed semen samples containing approximately 10 × 106 motile sperm. The laparoscopic insemination technique provided higher pregnancy rate (45.5%) than vaginal insemination technique (7.7%) (p < .05). In conclusion, the described laparoscopic AI might be a new alternative technique, thus enabling limited or low-quality frozen sperm samples to establish pregnancy in rabbits. 相似文献

COMPARISON OF THE EFFECT OF LAPAROSCOPIC AND CONVENTIONAL PYLORIC SURGERY ON GASTRIC EMPTYING IN DOGS 总被引：1，自引：0，他引：1

The effect of a laparoscopic approach and pyloric surgery on canine gastrointestinal activity, particularly gastric emptying time, is not well understood. The purpose of this study was to compare the effect of laparoscopic and conventional pyloric surgery, in Ramstedt pyloromyotomy and Heineke-Mikulicz pyloroplasty, on complete gastric emptying time in 20 clinically normal dogs. Dogs were divided into four groups of five animals: dogs with laparoscopic Ramstedt pyloromyotomy, conventional Ramstedt pyloromyotomy, or laparoscopic Heineke-Mikulicz pyloroplasty, and the conventional Heineke-Mikulicz pyloroplasty group. Gastric emptying time using barium sulfate mixed with dry kibble dog food was measured fluoroscopically before and 1 month after surgery. Gastric emptying of solids was significantly enhanced in the pyloroplasty groups in the postoperative period compared with preoperative emptying. Just as after conventional pyloromyotomy, gastric emptying time after laparoscopic pyloromyotomy was not statistically different as compared with preoperative values. This study indicates that the fluoroscopic test meal is a valuable tool for defining complete gastric emptying time in normal dogs. We conclude that pyloromyotomy was less effective in decreasing complete gastric emptying time than Heineke-Mikulicz pyloroplasty in normal dogs. The possibility of decreasing complete gastric emptying time by laparoscopic surgery suggests a potential clinical application for this technique in small animals. 相似文献

Objective —To report a ventral abdominal approach and a ligating loop technique for laparoscopic cryptorchidectomy in horses.
Study Design —Prospective.
Sample Population—Six horses, aged 1 to 5 years, with retained testes.
Methods —One laparoscopic portal and three to four instrument portals were used for ventral abdominal laparoscopic cryptorchidectomy. Laparoscopic instruments were used to maneuver and secure the testis through a ligating loop (modified Roeder knot) that was secured from outside the abdominal cavity. Only minimal enlargement of one instrument portal was used to remove the testicle.
Results —Three horses were bilateral cryptorchids, and three were unilateral (left side, two; right side, one) cryptorchids. Operative time, defined as the time from laparoscope insertion to removal, ranged from 20 to 25 minutes for unilateral cryptorchids and from 40 to 50 minutes for bilateral cryptorchids.
Conclusions —The reported technique allowed decreased tension on the tissues during ligation and removal of the testis from the peritoneal cavity. Improved observation of the abdominal cavity, ligation security, shortened patient confinement time, and minimally invasive technique are all considered to be benefits of laparoscopic cryptorchidectomy.
Clinical Relevance —Direct observation of retained testes and intraabdominal castration are distinct advantages of the use of laparoscopy in horses that have had previous unsuccessful surgical attempts, horses with unknown histories that have retained testicular tissue, or bilateral abdominal cryptorchids. 相似文献

OBJECTIVE: To describe a laparoscopic technique for sterilization of the male donkey using an endoscopic linear stapler (ELS). STUDY DESIGN: Clinical report. ANIMALS: Male Sardinia donkeys (n=6), aged 24-36 months. METHODS: Laparoscopic sterilization was performed under standing sedation or recumbent under general anesthesia. An endoscopic linear stapler was used to transect, and control hemorrhage of, the spermatic cord. Serum testosterone concentrations were measured preoperatively and at 3, 6, and 12 months after sterilization. One testis from each of 2 donkeys was collected at 12 months for histologic examination. RESULTS: Sterilization was successfully achieved. The only minor intraoperative complication experienced was hemorrhage from 1 spermatic cord stump, which was re-stapled. No other major short- or long-term complications occurred. Serum testosterone concentrations were < 15 ng/dL at 3, 6, and 12 months after surgery in all donkeys. Testicular atrophy without evidence of revascularization was observed in the 2 testes examined histologically. CONCLUSIONS: Sterilization of descended testes by intraabdominal laparoscopic transection of the spermatic cord is a simple practical method, with minimal intraoperative or postoperative complications. Testicular revascularization did not occur. CLINICAL RELEVANCE: Laparoscopic sterilization in donkey can be performed using an endoscopic linear stapler as an alternative to scrotal castration. 相似文献

Objectives: To report experience with laparoscopic‐assisted intestinal resection and anastomosis for treatment of discrete intestinal masses using a novel wound retraction device. Study Design: Case series. Animals: Dogs (n=2) and cats (6). Methods: Dogs and cats with discrete intestinal masses identified by ultrasonography without evidence of intestinal perforation or peritonitis, were included. A 2 portal technique was used; 1 portal was enlarged for insertion of the wound retraction device through which the intestine was examined as thoroughly as possible. The diseased portion of the intestine was exteriorized through the wound retractor and resection and anastomosis of the intestinal mass performed. Results: Of the 8 animals, laparoscopic‐assisted intestinal resection and anastomosis through the wound retractor was performed in 2 dogs and 3 cats. In 3 cats, based on either location or extent of the lesion, 2 were converted to laparoscopic‐assisted intestinal biopsies and 1 to an open colocolostomy. No other intra‐ or perioperative complications were encountered and all animals survived to discharge. Conclusions: Laparoscopic‐assisted intestinal resection and anastomosis can be performed in select canine and feline patients with modestly sized, discrete intestinal masses. 相似文献

Laparoscopic cryptorchidectomy without insufflation was applied in 10 standing bulls aged
3 to 15 months. Nine bulls were preoperatively pointed out intra-abdominal testes by
computed tomography. Preoperative fasting for a minimum of 24 hr provided laparoscopic
visualization of intra-abdominal area from the kidney to the inguinal region. Surgical
procedure was interrupted by intra-abdominal fat and testis size. It took 0.6 to 1.5 hr in
4 animals weighing 98 to 139 kg, 0.8 to 2.8 hr in 4 animals weighing 170 to 187 kg, and 3
and 4 hr in 2 animals weighing 244 and 300 kg to complete the cryptorchidectomy. In
conclusion, standing gasless laparoscopic cryptorchidectomy seems to be most suitable for
bulls weighing from 100 to 180 kg. 相似文献
