OBJECTIVE: To report a technique for correction of atresia ani and rectovestibular fistula with fistula preservation, and outcome in 2 dogs. STUDY DESIGN: Case report. ANIMALS: Two intact female puppies. METHODS: The fistula was approached by episiotomy. A vertical median perineal incision was made starting dorsal to the anal region and extended to surround the fistula. The rectum and vagina were separated, and the end of the fistula was sutured to the skin. RESULTS: Early postoperative complications included constipation, fecal incontinence, and perineal soiling, but long-term outcome was good in both dogs. CONCLUSION: With careful dissection, the fistula and internal anal sphincter can be preserved and used in the surgical reconstruction of the anal canal and anus. CLINICAL RELEVANCE: Preservation of the fistula may provide an internal sphincter that contributes to a better functional result during correction of atresia ani. A surgical approach that combines episiotomy and perineal incision for separation of the vagina and rectum, and preserves the fistula may decrease the risk of dehiscence.  相似文献

Five dogs with rectovaginal fistula and atresia ani that had been treated by surgical correction of the malformations were studied retrospectively. Ages at presentation varied from 1 to 3 months and weight from 350 g to 7.5 kg. The histories included voiding of feces through the vulva, with or without tenesmus, usually observed after weaning. Atresia ani, presence of feces in the vaginal canal, abdominal distention, and discomfort on abdominal palpation were observed during clinical examination. Also, 3 dogs had partial tail agenesis. In all dogs, the rectovaginal fistula was isolated and transected, the vulvar and rectal defects were closed separately, and the atresia ani was repaired. Normal defecation was restored, but 1 dog had fecal incontinence that subsequently resolved. One dog died 2.5 months postoperatively, and follow-up was done on the others for periods ranging from 1.6 year to 7.7 years. Surgical correction in dogs with rectovaginal fistula and atresia ani may result in a favorable outcome, if it is done early.  相似文献

An incompetent vulvar seal leads to reproductive failure, and a surgical intervention might be required. The present paper describes modifications to Pouret's surgery. We suggest the use of a simple interrupted vertical mattress suture, which avoids seroma. Eighteen Brazilian Jumping Horse mares, older than 20 years and barren for 3-5 consecutive years, underwent modified Pouret's surgery. A horizontal skin incision of 3-4 cm was made half way between the anus and upper commissure of the vulva. The submucosal and connective tissue were dissected, and the rectovaginal shelf was split horizontally by sectioning the muscular and ligamentous connections between the anus, vulva, caudal portion of the rectum, and vagina until the vulva was oriented vertically. The wound was changed from a horizontal plane to a vertical plane by placing the suture vertically using approximately eight interrupted U sutures distributed in two layers with polyamide thread. The modified Pouret's surgical technique provided a perfect coaptation of the vulvar lips and a correct perineal position. Those mares that presented with horizontally tipped vulvar lips due to advanced age and stretching of the pelvic tissues by multiple foaling had their vulvas replaced. Also, the surgical procedure was easy to perform. As to fertility, of the 18 initial mares, 14 were inseminated, and all became pregnant. Thus, it was possible to conclude that the anatomical changes performed throughout the surgical procedure predisposed to a better vulvar coaptation, correcting the pneumovagina.  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

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

Summary

A modified technique for transposition of the internal obturator muscle was used to repair perineal hernias in 100 dogs. Complications and long‐term results are described. The most important complications were wound infection (45%), faecal incontinence (15%), and perineal fistula (7%). These complications often occurred in combination. The recurrence rate of perineal hernia was 5%.

Nine of the 15 patients with faecal incontinence had paresis of the external anal sphincter or faecal incontinence before surgery. We suggest that in numerous patients, faecal incontinence is a complication of the condition rather than a complication of treatment. The owner's assessment of the surgical result was good in 71% and moderate in 18% of the cases.  相似文献

Enteric duplication is a rare developmental malformation in people, dogs and cats. The purpose of the present report is to describe the first case of a rectal duplication cyst in a 7-year-old domestic shorthair cat presenting for acute constipation and tenesmus. On rectal palpation a spherical mass compressing the lumen of the rectum could be felt in the dorsal wall of the rectum. A computed tomography (CT) scan confirmed the presence of a well demarcated cystic lesion in the pelvic canal, dorsal to the rectum. The cyst was surgically removed via a perineal approach. No communication with the rectal lumen could be demonstrated. Histopathological examination was consistent with a rectal duplication cyst. Clinical signs resolved completely after excision of this conjoined non-communicating cystic rectal duplicate.  相似文献

Older male dogs often exhibit the symptoms of rectum diverticulum and perineal hernia. In order to point out the often common reason of these disorders, the term "rectum diverticulum/perineal hernia complex" has been introduced. In a large group of such patients two methods of surgical correction of this problem were retrospectively evaluated. Only patients were included in this evaluation that were euthanized if recurrence occurred. In 21 patients (group 1) the often performed method of Bojrab was used, both in rectum diverticulum and in perineal hernia operations. In group 2 15 dogs were subjected to the same operation technique, but we performed an additional pleating contraction of the herniated gut wall layers. In case of visible recurrence at an age of at least 11 years the dogs were euthanized. Group 1 showed a postoperative survival time of 3.61 +/- 0.96 years until recurrence, group 2 revealed recurrence not before 4.93 +/- 0.93 years post operationem. The difference is significant (p < 0.05). It is the opinion of the authors that additional longitudinal contracting by pleating of the gut markedly prolonges the point of time when recurrence appears.  相似文献

This study evaluated the safety of preoperative computed tomography angiography (CTA) and its effect on surgical time and clinical outcomes in dogs that underwent surgical correction of a single congenital extrahepatic portosystemic shunt (CEPSS). Patient data were retrospectively collected from medical records and owner communications for 124 dogs with single CEPSS, undergoing preoperative CTA (n = 43) or not (n = 81) which were surgically treated from 2005 to 2014. The frequency of major postoperative complications was 4.7% and 9.9% for the CTA and no CTA groups, respectively (P = 0.49). Mean ± standard deviation (SD) surgical time for the preoperative CTA group was 84 ± 40 min and 81 ± 31 min for the no CTA group (P = 0.28). We conclude that anesthetized preoperative CTA appears to be a safe method for diagnosis and surgical planning in dogs with single CEPSS, and does not appear to affect surgical procedure time, complication rate, or clinical outcome.  相似文献

Vulvovaginectomy and perineal urethrostomy were performed in three dogs with extensive neoplasms of the vulva and vagina. One benign tumor (fibroleiomyoma) and two malignant tumors (transitional cell carcinoma and anaplastic spindle cell sarcoma) were diagnosed. Survival times were 9 weeks to 10 months. Urinary continence was preserved in all three dogs. The procedure may be curative for benign tumors or malignant tumors that have not yet metastasized; it is a palliative procedure for advanced malignancies.  相似文献

The records of 31 cats and eight dogs undergoing surgical correction of peritoneopericardial diaphragmatic hernia (PPDH) from 2000 through 2007 were reviewed. Weimaraners and long-haired cats of varying breeds, particularly Maine Coon cats, appear to be at higher risk of PPDH. Presenting complaints were most commonly related to the respiratory and gastrointestinal tracts in both dogs and cats, although respiratory signs were more prevalent in cats, and gastrointestinal signs were more common in dogs. The most common herniated organs were liver, gallbladder, and small intestine. Mortality associated with surgical repair of PPDH in cats and dogs was low in the first 2 weeks postoperatively, and prognosis for return to normal function was excellent. Peri-and postoperative complications were typically minor and self-limiting.  相似文献

OBJECTIVE: To determine whether the cranial portion of the vagina of dogs is a suitable site for measuring intra-abdominal pressure during cystometry. ANIMALS: 16 bitches (8 sexually intact and 8 spayed). PROCEDURE: 2 types of vaginal catheters were used to measure intra-abdominal pressure changes in anesthetized dogs. Catheters were inserted in the rectum and cranial portion of the vagina. RESULTS: Intra-abdominal pressure variations were detected with greater magnitude in the rectum than the cranial portion of the vagina, regardless of type of catheter used and reproductive status (sexually intact vs spayed) of the dogs. CONCLUSIONS AND CLINICAL RELEVANCE: The rectum was the better site for measuring intra-abdominal pressure changes in female dogs. Measurement of intra-abdominal pressure with concomitant measurement of intravesical pressure to determine detrusor pressure during cystometry in female dogs is more reliably detected from the rectum than the cranial portion of the vagina.  相似文献

A 4 1/2-year-old female spayed ferret (Mustela putorius furo) was presented for a rapidly growing mass in the inguinal region. Following a complete clinical evaluation, the unusual mass was surgically removed and the histopathological diagnosis was an inguinal liposarcoma. No post-operative complications were observed over a 14-month follow-up period.  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

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

Congenital anorectal abnormalities were diagnosed in three male and three female dogs. One dog had anal stenosis, three had a persistent anal membrane, and the other two had an imperforate anus associated with a rectovaginal fistula. Five of the dogs were treated surgically, and four of them which were followed up for periods ranging from one to five years continued to pass faeces normally.  相似文献

Background: Parenteral nutrition (PN) is increasingly used to support hospitalized dogs and cats. Published assessments of outcome are limited. Objective: Evaluate type and prevalence of complications and risk factors for death and complications in dogs and cats receiving PN. Animals: Three hundred and nineteen dogs and 112 cats that received PN at a teaching hospital between 2000 and 2008. Methods: Retrospective case review. Diagnosis, duration of PN administration, concurrent enteral feeding, death, and mechanical, septic, and metabolic complications were abstracted from medical records. Association of each parameter with complications and death was analyzed by binary logistic regression. Results: Pancreatitis was the most common diagnosis (109/319 dogs, 34/112 cats), and 137/319 dogs and 51/112 cats died. Dogs and cats received 113 ± 40% and 103 ± 32% of resting energy requirement, respectively. Mechanical (81/319 dogs, 16/112 cats) and septic (20/319 dogs, 6/112 cats) complications were not associated with death (P > .05). Hyperglycemia was the most common metabolic complication (96/158 dogs, 31/37 cats). Hypercreatininemia in dogs (8/79) was the only complication associated with death (P < .01). Chronic kidney disease in dogs, hepatic lipidosis in cats, and longer duration of inadequate caloric intake before PN in both species were negatively associated with survival (P < .05). Factors positively associated with survival included longer duration of PN administration in both species, enteral feeding in cats with any disease, and enteral feeding in dogs with respiratory disease (P < .05). Conclusions and Clinical Importance: PN can be effectively used to provide the energy requirements of most critically ill dogs and cats. Most complications accompanying PN administration do not affect survival.  相似文献
