This is an example of reconstructive surgery after excision of a large (6.5 cm wide) Soft Tissue Sarcoma-STS in a dog. The STS grew moderately on the left pelvic limb, half way between the stifle and femoral greater trochanter. The defect was reconstructed with a large Inguinal Flank fold Flap. Results revealed a grade 2 STS, clean margins. No major post-operative complications. Follow the pictures examples of the technique. Fig.1. Initial view of the STS Fig.2. Lateral margins of the excision and the planned reconstructive technique. Fig.3. View of the excision defect and harvesting of the inguinal flank fold flap Fig.4. Final view after the Inguinal Fold Flap is sutured…

This is a Infiltrative Odontogenic Fibroma (IOF) in a young 2 yo male dog. Treatment of choice was hemimandibulectomy. Good recovery and started eating 2 hours after surgery. Fig. 1. CT evidence of bone infiltration of the fibroma Fig. 2. Xray of the hemimandible after surgery. Note the bone infiltration Fig. 3. Postoperative image of the hemimandible with IOF Dr. Daniel Lescai DVM MS PhD CSAVP-STS

CAA (Canine Acabthomatous Ameloblastoma) is a common tumor in dogs with 45.5% of situations affecting rostral mandible. This the case of a male dog, castrated, 10 yo with a large mandibular tumor with bone invasion as seen on CT scan. Curative intent surgery implies a bilateral rostral mandibulectomy. Clean margins after surgery, good cosmesis, good function and a cured old dog. Fig.1. X-ray of the mandible after resection with the bone invasion clearly visible Fig. 2. CT scan of the same dog, note the bone invasion of the CAA Fig. 3. Large CAA affecting the rostral mandible Fig. 4. Mandibular canal after osteotomy and use of bone wax. Fig. 5.…

The resection of the ileocolic junction (ICJR) leads to the loss of regulation of both anterograde and retrograde reflux. The loss of anterograde resistance can potentially result in diarrhea, nutrient malabsorption, and even dehydration due to accelerated chyme transit. Resection of the ileocolic junction (ICJ) is sometimes performed alongside the resection of the terminal ileum. Bile acids and cobalamin are reabsorbed in the ileum; therefore, if a significant portion of the ileum is resected along with the ICJ, bile salt malabsorption, intestinal dysbiosis, and hypocobalaminemia may occur, potentially causing chronic diarrhea. FGESF presents as eosinophilic masses that are associated with the gastrointestinal tract and associated abdominal lymph nodes, often localized…
