An 8-year-old 6.8-kg neutered male Dachshund was presented for evaluation of vomiting, diarrhea, anorexia, and swelling over the right perineal region. The dog had a history of a bilateral perineal herniorrhaphy and castration 14 months prior to presentation.
Bilateral perineal hernias were confirmed by digital rectal examination. Abdominal ultrasonography confirmed the presence of intestine within the right hernia. Three days after admission to the hospital, the region of the right perineal hernia became painful, erythematous, and edematous. Computed tomography revealed jejunal incarceration within the right hernia with dilation of 1 jejunal segment that indicated intestinal obstruction.
TREATMENT AND OUTCOME
Abdominal exploratory surgery was performed, during which irreducible small intestinal incarceration was confirmed. Intra-abdominal jejunal resection and anastomosis was performed, and an approximately 13-cm-long section of the jejunum was resected. Bilateral perineal herniorrhaphies with internal obturator and superficial gluteal muscle transposition were performed. Six months after surgery, digital rectal examination of the dog revealed that the repair was intact. The dog had no perineal hernia–related clinical signs at the time of the recheck examination.
For the dog of the present report, surgical management of small intestinal strangulation associated with a perineal hernia was successful. Although a portion of the small intestines can frequently be found within perineal hernias in dogs, perineal hernia-related small intestinal strangulation has not been previously described, to the authors’ knowledge. Veterinarians and clients should be aware of this potential complication secondary to perineal hernia and be prepared to perform an abdominal surgical procedure to address small intestinal incarceration in affected dogs.
To retrospectively compare the incidence of incisional complications in dogs undergoing surgery for mast cell tumors (MCTs) and soft tissue sarcomas (STSs).
Dogs that underwent excision of ≥ 1 MCT, STS, or both from January 2014 to July 2019 and had ≥ 30 days postoperative follow-up were included. Signalment; anesthesia and surgery time; administration of propofol; tumor type, grade, location, and size; intended surgical margins; histologic margins; perioperative radiation, chemotherapy, and corticosteroid and antihistamine (MCT group) treatments; and incisional complications (classified as major or minor) were recorded. Follow-up information was obtained from owners or primary care veterinarians, if needed. Incidence and severity of incisional complications were compared between the MCT and STS groups. Potential risk factors were assessed for associations with incisional complications by simple and multiple logistic regression analysis.
The 218 dogs underwent surgery for 293 tumors (209 MCTs and 84 STSs). Complication rates did not differ between MCT (28/209 [13%]) and STS (12/84 [14%]) groups. For the MCT group, incomplete margins (vs complete or narrow), increasing Patnaik tumor grade, and postoperative chemotherapy (yes vs no) were associated with increased odds of incisional complications on simple regression. On multiple logistic regression, postoperative chemotherapy was associated with increased odds of incisional complications for the MCT group and both groups combined.
CONCLUSIONS AND CLINICAL RELEVANCE
On the basis of the results, we suggest that chemotherapy be used with caution ≤ 30 days after surgery for dogs with MCTs. Corticosteroid administration was not associated with incisional complications for the MCT group in this study.
OBJECTIVE To quantitatively measure the amount of pressure induced at the calcaneus and cranial tibial surface of dogs by use of 2 cast configurations.
ANIMALS 13 client- or student-owned dogs.
PROCEDURES Pressure sensors were placed over the calcaneus and cranial tibial surface. Dogs then were fitted with a fiberglass cast on a pelvic limb extending from the digits to the stifle joint (tall cast). Pressure induced over the calcaneus and proximal edge of the cast at the level of the cranial tibial surface was simultaneously recorded during ambulation. Subsequently, the cast was shortened to end immediately proximal to the calcaneus (short cast), and data acquisition was repeated. Pressure at the level of the calcaneus and cranial tibial surface for both cast configurations was compared by use of paired t tests.
RESULTS The short cast created significantly greater peak pressure at the level of the calcaneus (mean ± SD, 0.2 ± 0.07 MPa), compared with peak pressure created by the tall cast (0.1 ± 0.06 MPa). Mean pressure at the proximal cranial edge of the cast was significantly greater for the short cast (0.2 ± 0.06 MPa) than for the tall cast (0.04 ± 0.03 MPa).
CONCLUSIONS AND CLINICAL RELEVANCE A cast extended to the level of the proximal portion of the tibia caused less pressure at the level of the calcaneus and the proximal cranial edge of the cast. Reducing the amount of pressure at these locations may minimize the potential for pressure sores and other soft tissue injuries.
