The case records of 47 mares with third-degree perineal lacerations or rectovestibular fistulae were examined to evaluate their fertility following surgical repair. Of 32 mares bred, 24 became pregnant, suggesting that surgical repair is indicated in any mare with sufficient genetic potential. Perineal trauma after surgical repair was recorded in 3 of 20 mares at subsequent parturition. 相似文献

The case records of 12 mares at the Ontario and Atlantic Veterinary Colleges were reviewed to evaluate the success rates of surgical techniques used to repair rectovaginal fistulae. A modified horizontal perineal technique was used in eight mares; it was unsuccessful in one mare, but the fistula was subsequently successfully repaired using the same technique. One rectovaginal fistula that was converted to a third-degree perineal laceration was successfully repaired on the third attempt, using the suture principles of the modified horizontal perineal technique. A modified transvaginal technique was used in three mares, in two of which it failed; their fistulae were subsequently converted to third-degree perineal lacerations and repaired using a one-stage closure. We conclude that the modified horizontal perineal technique is a one-stage procedure that is technically easy to perform, results in less tension on the suture lines, and is effective in modifying poor vulvar conformation. 相似文献

The case records of 20 cows with either a third-degree perineal laceration or rectovestibular fistula were reviewed to ascertain the signalment, history, treatment, and long-term result of treatment. Fifteen cows, including 10 first-calf cows, had third-degree perineal lacerations that occurred at calving. Surgery was done in 14 of 15 cows; 10 of the 14 (71%) remained fertile. The cow that was not treated surgically was culled after 24 months because of infertility. Five cows had a rectovestibular fistula; 4 of these were treated surgically. The cow that did not have surgery healed by second intention and remained fertile, and 3 of the 4 cows in which surgery was performed were fertile. None of the cows that produced calves after the initial injury suffered a perineal laceration at subsequent calvings. Single-stage surgical repair of third-degree perineal laceration or rectovestibular fistula appeared to have a good prognosis for subsequent fertility in cows. 相似文献

Bladder eversion is a rare condition and may occur in mares as a result of excessive straining during pregnancy or in the postpartum period. In the present case, bladder eversion was caused by chronic cystitis in a nonpregnant mare. An Arabian racehorse (mare, 3 years old) was admitted to The Racehorse Hospital of the Turkish Jockey Club with a history of lumbar pain, excessive straining, and frequently assuming the urination position. Physical examination revealed the presence of tenesmus, stranguria, passing of small amounts of urine, and a visible mucosal structure at the ventral vulvar commissure during tenesmus. Laboratory findings revealed leucocytosis, increased urine pH, proteinuria, pyuria, and hematuria. Streptococcus equi subsp. zooepidemicus and Escherichia coli were isolated and identified in urine culture. Transrectal ultrasonography revealed thickening of the bladder wall and prolapse of the bladder corpus into the bladder. In the cystoscopic examination, performed following bladder reduction, severe hyperemia, erosion, and ulcers were determined in the bladder mucosa. Chronic cystitis was treated using antibiotics, based on urine culture test results, together with steroids and non-steroidal anti-inflammatory drugs. Twenty-four hours after the start of treatment, the severity of straining was observed to have decreased, ceasing completely on Day 4, and the bladder returned to its normal position. 相似文献

The bladder of a 750-kg Clydesdale mare had everted through the urethra into the vagina immediately after parturition. The bladder was reinverted into the peritoneal cavity by an attending veterinarian, but 4 days later, the bladder was everted again in the vagina. The mare was able to void urine through both ureters, which could be seen in the mucosal surface of the bladder. The everted bladder had become edematous and could not be reinverted through the urethra. A considerable portion of the fundus was necrotic. The mare was administered xylazine epidurally to induce perineal analgesia, and the necrotic portion of the bladder was resected and healthy bladder tissue was opposed with a double layer of simple continuous sutures. The urethral sphincter was longitudinally incised through the vaginal mucosa to allow reinversion of the bladder through the urethra. A purse-string suture inserted in the urethral opening decreased the urethral diameter and prevented recurrence of the condition. An inflated Foley catheter was maintained in the bladder for 5 days. The mare recovered normal urination after the catheter was removed. 相似文献

A modified one-stage surgical repair was performed on eight mares that suffered from third-degree rectovestibular lacerations. The rectovestibular septum was reconstructed by three lines of sutures using polydioxanone. Primary healing was achieved in seven mares. Four mares got pregnant after the surgery, and no further injury was noticed at subsequent delivery. Complications of the currently used technique included pneumorectum (in one mare) and rectovestibular fistula (in another mare). The obtained results indicated that mares with third-degree rectovestibular lacerations are candidates for this modified one-stage technique with satisfactory outcome for subsequent fertility. 相似文献

The endometrial response of mares to repair of third-degree rectovestibular lacerations was evaluated. Endometrial biopsy specimens from 8 mares with third-degree rectovestibular laceration were obtained immediately before surgery and from 9 to 15 days after repair. Presurgical endometrial biopsy specimens were classified as category I for 2 mares; category II, attributable to slight endometritis, for 5 mares; and category III, attributable to moderate-to-severe endometritis, for 1 mare. Within 15 days after rectovestibular repair, all endometrial biopsy specimens were classified as category I. Results indicated that mares with third-degree rectovestibular injuries are candidates for breeding by artificial insemination by 2 weeks after repair of the injury. 相似文献

A modified surgical technique has been developed for repairing third-degree perineal lacerations in mares. Complications of the currently used methods include rectovaginal fistula formation, urine pooling, complete dehiscence of the repair, constipation, tenesmus and difficulty of performance in the practice. The modified method is simpler and more practical. This method was performed on eight Thoroughbred mares with third-degree perineal lacerations after delivery. The rectovestibular septum was reconstructed by three lines of sutures in a transverse direction in relation to the longitudinal axis of the rectum. In one of the eight cases pneumorectum was observed after using the new method. The conception rate obtained after using the new surgical technique was 62.5%. Pregnant mares delivered normally without any new lacerations at the subsequent parturition. It can be concluded that this new surgical technique can be used successfully for repairing third-degree perineal lacerations in mares. 相似文献

Two broodmares were diagnosed with rupture of the urinary bladder. One mare revealed abnormalities post partum and the other associated with ante partum uterine torsion. The clinical symptoms included mild abdominal pain, anorexia, decreased urinary volume and increased peritoneal fluid. In one mare, based on the creatinine level of the peritoneal fluid and serum biochemical abnormalities, uroperitoneum was diagnosed. In the other mare, the bladder rupture was found during the celiotomy for surgical repair of uterine torsion that was diagnosed upon rectal examination. Surgery was performed without a urethral sphincterotomy. The vaginal floor was incised in a standing position and the bladder was diverted into the vagina in order to suture the tears located in the ventrocaudal aspect of the bladder. Both mares survived after treatment for uraemia. Bladder rupture, although uncommon, may affect peripartum mares. Approach to the ruptured bladder without urethral sphincterotomy in a standing position should be considered as a choice for surgical repair. 相似文献

A case of retroflexion of the urinary bladder into a bilateral perineal hernia in a female domestic shorthaired cat, three weeks postpartum, is reported. The bladder was repositioned and a cystopexy performed. A pelvic ostectomy was also carried out in order to alleviate the narrowing of the pelvic canal caused by an untreated acetabular fracture. Bilateral perineal herniorrhaphy was performed. 相似文献

An 11-year-old mare presented 36 hours after foaling with a ruptured bladder. Uroperitoneum was diagnosed on ultrasound and from the creatinine concentration of the peritoneal fluid. Bladder endoscopy demonstrated tissue necrosis and a rent in the dorsocranial aspect of the bladder. Following stabilisation, including abdominal drainage and lavage, the mare was taken to standing surgery. Under continuous sedation and epidural anaesthesia, and after surgical preparation, a Balfour retractor was placed in the vagina. Using sterile lubricant and moderate force, it was possible to insert a hand into the bladder. The tear was easily palpable on the dorsal portion of the bladder. Two fingers were inserted through the tear and used to provide traction to evert the bladder completely into the vagina where it could grasped with the surgeons other hand to prevent further trauma. A second surgeon could then visualise the entire tear and repaired this using a single layer of size zero PDS suture in a single continuous pattern. As soon as the bladder was repaired, it was replaced via the urethra. The mare did well after surgery and was discharged after 48 hours, apparently normal.This report is the first describing repair of the bladder without an abdominal incision or incision into the urethral sphincter. This greatly reduces the chance of possible complications such as urine pooling after surgery with the previously described standing technique or bladder trauma due to traction with abdominal surgery. 相似文献

Perineal herniation in the bitch is rare and its complication by bladder retroflexion in the bitch has not been previously reported in the literature. This case report describes a multigravid, five-year-old female cocker spaniel with bilateral perineal hernias, complicated by marked rectal sacculation and ventral bladder retroflexion. The case was managed initially by cystopexy and colopexy, followed seven days later by bilateral perineal herniorrhaphy. There was no recurrence of the problem by 12 months postsurgery. 相似文献

Proximal urethral obstruction was diagnosed 2 days after bilateral perineal herniorrhaphy in a 12-year-old male Pomeranian-cross dog. The obstruction was caused by ligation of the proximal urethra during resection of a presumed paraprostatic cyst. Surgical repair involved reconstruction of the urethra and bladder wall, but urinary incontinence persisted. 相似文献

Two sexually intact adult male chinchillas were presented with a swelling in the perineal region. Radiographically both masses had a soft tissue opacity. Ultrasonography confirmed the tentative diagnosis of perineal hernia. In the first case the ultrasonographic examination revealed a fluid-filled structure inside the swelling, which was determined to be the urinary bladder. In the second case the hernia sac was filled with homogeneous tissue, belived to be fat. Subsequently, unilateral perineal herniorrhaphies including an internal obturator muscle flap transposition technique were performed. Both chinchillas recovered well with subsequent uneventful healing of the surgical sites. No long-term complications or recurrences of the perineal hernias were reported. This clinical report shows that perineal hernias occur in chinchillas and can be surgically treated with success. 相似文献

Objective— To describe a surgical technique for repair of grade IV rectal tears after parturition in mares and to report outcome.
Study Design— Clinical report.
Animals— Horses (n=6) with grade IV rectal tears.
Methods— Mares were sedated and restrained in standing stocks. After caudal anesthesia and evacuation of feces from the rectum, the perineal region was aseptically prepared. Four stay sutures were placed through the external anal sphincter before vertical transection (12 o'clock). Caudal retraction of the tear was performed using Allis tissue forceps (5 mares) or stay sutures before accurate apposition of the tear margins with steel staples below the tissue forceps. The mucosal edges were then sharply dissected leaving ∼5 mm edges which were apposed in a single layer (2-0 poliglecaprone 25) before stapler release. In 1 mare, the rectal tear was identified and apposed using a 2-layer hand-sutured closure. Systemic antibiotics and anti-inflammatory agents were administered postoperatively (5 mares) and standing abdominal lavage performed (3 mares).
Results— Four mares survived long term and subsequently became pregnant. Immediately after surgical repair, 1 mare was anesthetized for exploratory celiotomy and abdominal lavage but fractured her pelvis during recovery from anesthesia and was euthanatized. A 2nd mare was euthanatized after 72 h because of severe diffuse peritonitis; however, the repair was still intact.
Conclusion— In standing mares, rectal tears can be exteriorized by prolapse through the anal sphincter after sphincterotomy and repaired in 2 layers with staples oversewn with a continuous suture pattern.
Clinical Relevance— Rectal tears occurring as a result of parturition can potentially be repaired efficiently using an oversewn stapled primary closure technique. 相似文献

This study was designed to evaluate the modified Goetz-one-stage repair technique for reconstruction of third-degree perineal lacerations (TDPLs) in female camels. Fifteen female dromedary camels with TDPL were surgically reconstructed using the modified Goetz one-stage repair using the three-line closure technique. The surgical outcomes, the interval between repair and breeding, and the postoperative conception of the operated female camels were recorded and analyzed. During the 12-month postoperative follow-up period, TDPLs in 14 female camels (93.33%) healed completely by the first intention with mild inflammatory edema and infection in 2 female camels. One camel (6.67%) had a rectovaginal fistula, which was successfully repaired with suturing through the vaginal approach. Of the 15 female camels, 13 (86.67%) subsequently became pregnant through natural mating within 3 to 6 months postoperatively; however, 2 (13.33%) were one was immature and the other was barren which referred for gynecological treatment. The modified Goetz one-stage repair technique was successful in 14 of the 15 female camels after a single surgery, with a low incidence of postoperative complications. This technique is efficient for the repair of TDPLs in female camels, with promising results for subsequent fertility. 相似文献

This report details a case of iatrogenic bladder rupture in a gelding that was successfully treated with conservative management. Rupture occurred at the time of attempted cystoscopy, whilst the bladder was being insufflated with air for further investigation of stranguria and suspected urolithiasis. The gelding was treated with temporary perineal urethrostomy, peritoneal lavage and drainage of urine from the bladder and made a complete recovery. 相似文献

Third-degree perineal lacerations or rectovestibular fistulae in 17 mares were repaired surgically by a one-stage method. Primary healing occurred in 14 mares; there were one complete dehiscence and two partial dehiscences with fistula formation. Twelve of 13 mares that were bred became pregnant; nine carried foals to term and two are still pregnant. Two mares have each produced one unthrifty foal. One mare repeatedly aborts in the first trimester. Four mares have produced several healthy foals with no further problems. One mare suffered further perineal trauma while foaling. 相似文献
