    Study Notes

    Surgical Procedures for Ear and Salivary Gland Pathologies

    • Aural hematoma is a common condition caused by excessive head shaking/scratching/rubbing, resulting in the rupture of blood vessels in the pinna.
    • Treatment options for aural hematoma include addressing the underlying cause, ear cytology and culture, otoscopy, and conservative or surgical management.
    • Surgical treatment of aural hematoma involves creating an S-shaped incision to drain the hematoma and using stent sutures to tack the skin and cartilage together.
    • Pannectomy is a surgical procedure performed for neoplasia affecting the ear, commonly mast cell tumors (MCT) in dogs and squamous cell carcinoma (SCC) in cats.
    • Total ear canal ablation and bulla osteotomy (TECA-BO) is the most common surgical procedure for chronic otitis externa/media and other ear pathologies.
    • TECA-BO involves removing the lateral wall of the ear canal, completely removing the canal epithelium, widening the external acoustic meatus, and performing bulla osteotomy.
    • Facial nerve, caudal auricular vein, retroglenoid vein, external carotid artery, maxillary vein, and internal carotid artery are important structures to be cautious of during TECA-BO.
    • Ventral bulla osteotomy is performed for otitis media without concurrent otitis externa, auditory polyp, or middle ear neoplasia, especially in cats.
    • Major salivary glands include the mandibular, sublingual, parotid, and zygomatic glands, and cats have an additional molar gland.
    • Sialocele is the most common salivary pathology, characterized by the accumulation of saliva in a pocket within the subcutaneous tissue.
    • Sialocele can present in various locations, including the submandibular, sublingual, zygomatic, and pharyngeal regions.
    • Surgical excision of the involved salivary glands with concurrent drainage is the treatment of choice for sialocele. Salivary gland neoplasia, sialolithiasis, and salivary gland carcinomas are other salivary gland pathologies that may require surgical intervention.

    Esophageal Disorders: Causes, Symptoms, and Treatment

    • The esophagus is divided into the nasopharynx, oropharynx, and laryngopharynx.
    • Cricopharyngeal dysphagia is a congenital swallowing disorder caused by the failure of the cricopharyngeus muscle to relax and accept food.
    • Achalasia is a condition characterized by asynchrony and repeated attempts to swallow.
    • Esophageal foreign bodies are fairly common, with bones being common in dogs and fish hooks and needles in cats. Symptoms include regurgitation, hypersalivation, and gagging.
    • Esophageal neoplasia, such as SCC and sarcomas, is rare but can cause symptoms like regurgitation, weight loss, and blood in saliva/vomit.
    • Esophageal stricture is a narrowing of the esophagus that causes obstruction, most commonly caused by reflux under anesthesia.
    • Esophageal fistulas are very rare and result in the development of a fibrous tract connecting the esophagus to the bronchus, trachea, or lung.
    • Vascular ring anomalies are abnormal developments of fetal vessels that encircle the esophagus, causing focal constriction. The most common type is PRAA with a left ligamentum arteriosum.
    • Esophageal surgery carries a higher risk of complications compared to other GI surgeries and requires gentle handling to avoid impacting the blood supply.
    • Esophagostomy tube placement is a common procedure used to bypass the oral cavity and pharynx for feeding and to monitor regional anatomy.
    • Esophagotomy is commonly performed for foreign body removal, and closure can be done with a single or double layer interrupted pattern.
    • Esophageal patching involves the use of autologous tissues or artificial materials to either buttress a closure or replace a portion of the esophageal wall.
    • Swallowing involves several phases, including the oropharyngeal phase, pharyngeal subphase, cricopharyngeal subphase, esophageal phase, and gastroesophageal propulsion. Regurgitation is a hallmark symptom of esophageal disease.

    Lecture 18: The Stomach Anatomy and Surgical Diseases

    • Anatomy of the stomach includes four major divisions: cardia, body, fundus, and pylorus.
    • Surgical diseases of the stomach include gastric foreign body (FB), hiatal hernia, gastroesophageal intussusception, hypertrophic pyloric gastropathy, and gastric neoplasia.
    • Gastric foreign bodies are common and present with clinical signs such as vomiting, dehydration, abdominal pain, and melena.
    • Diagnosis of gastric foreign bodies can be made using plain films, contrast studies, or ultrasound.
    • Hypochloremic metabolic alkalosis is a common bloodwork finding in cases of gastric foreign bodies.
    • Treatment for gastric foreign bodies includes rehydration, endoscopic removal, or surgery.
    • Hiatal hernia is the displacement of the stomach or other organs through the esophageal hiatus into the chest.
    • Hiatal hernias can be congenital or acquired and present with symptoms such as regurgitation, vomiting, dysphagia, and weight loss.
    • Diagnosis of hiatal hernias can be made using radiographs, contrast studies, or endoscopy.
    • Treatment for hiatal hernias may include medical management with gastroprotectants and prokinetics, or surgical procedures such as gastropexy or esophagopexy.
    • Gastroesophageal intussusception is the invagination of the stomach into the distal esophagus and is more common in young German Shepherds.
    • Treatment for gastroesophageal intussusception may require a ventral abdominal approach, reduction of the stomach back into the abdomen, and left-sided gastropexy.
    • Hypertrophic pyloric gastropathy is a pyloric outflow obstruction caused by benign hypertrophy of the muscularis or mucosa, and can be congenital or acquired. Treatment options include medical management or surgical techniques such as pyloromyotomy or gastroduodenostomy.

    Lecture 19: Abdominal Radiography and Common Gastric Pathologies

    • Abdominal radiography can be used to assess the gastrointestinal tract, with the descending colon always on the left side in a ventrodorsal view.
    • The stomach anatomy differs between dogs and cats, with the entire stomach lying more left of midline in cats.
    • Gas and fluid patterns in the stomach can vary depending on the position of the patient, with gas in the pylorus and fluid in the fundus in a left lateral view.
    • Gastrography, using positive contrast agents such as barium, can be used to identify the location of the stomach, evaluate mucosal margins, and assess gastric emptying.
    • Common gastric pathologies include gastric dilatation-volvulus (GDV), food bloat, gastric foreign bodies, and pyloric outflow obstruction.
    • GDV is a surgical emergency and can be diagnosed using radiographs that

    Diagnosis and Management of Peritonitis and Pancreatitis in Cats and Dogs

    • Peritonitis is a serious condition that can lead to death, with a 3x greater risk of death if the patient has a 7 mg/dl increase in blood urea nitrogen.
    • Stabilization of peritonitis patients should include immediate attention to heart rate, body temperature, and abdominal distension.
    • Medical management should be attempted before surgery, with treatment including fluid administration, feeding, critical care, and analgesia.
    • The most common and easiest at-home treatment for peritonitis is the administration of meloxicam, buprenorphine, oxymorphone/hydromorphone, and lidocaine.
    • Peritonitis is often associated with a severe inflammatory response, fibrin deposition in the abdomen, ileus, and reflex rigidity.
    • Common causes of peritonitis include primary and secondary types, as well as mechanical, chemical, and septic causes.
    • Septic peritonitis is the most common type and can be caused by various factors, including ruptured GI viscus, foreign bodies, neoplasia, and urosepsis.
    • Clinical presentation of peritonitis includes lethargy, inappetence, vomiting, diarrhea, hypotension, and possible arrhythmias.
    • Diagnostic tests for peritonitis include complete blood count, chemistry panel, radiographs, ultrasound, and abdominocentesis/fluid analysis.
    • Stabilization of peritonitis patients requires intravenous fluid resuscitation, correction of acidemia and electrolyte disturbances, and broad-spectrum antibiotics.
    • Surgical treatment of peritonitis involves abdominal exploration, decontamination, and lavage, as well as the placement of a closed suction drain.
    • Post-operative care for peritonitis patients is critical, with days 3-5 being the most worrisome. The prognosis for peritonitis patients is guarded, even with aggressive treatment.
    • Pancreatitis can be acute or chronic, with idiopathic being the most common cause. It can lead to life-threatening complications such as systemic inflammatory response syndrome (SIRS) and necrotizing pancreatitis.
    • Diagnosis of pancreatitis is challenging, with criteria including compatible clinical signs, increased serum concentrations of pancreatic lipase, exclusion of competing differential diagnoses, and compatible imaging findings.
    • Treatment for pancreatitis involves supportive care, including IV fluids, analgesia, anti-emetics, early enteral nutrition, and specific therapies for chronic cases.
    • Common complications of pancreatitis include SIRS, DIC, multiple organ dysfunction syndrome, acute respiratory distress syndrome, biliary tract obstruction, and gastroparesis.
