Polyethylene glycol-6000 (PEG) was evaluated as a clearing agent for lipemic serum from dogs. Effects of PEG-treatment in lipemic and non-lipemic samples were determined for 13 chemical and enzymatic assays (glucose, BUN, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, amylase, total protein, albumin, sodium, potassium, chloride, phosphorus, and calcium). Control samples for lipemic sera were prepared by ultracentrifugation. Treatment with PEG cleared all lipemic samples. Regression lines for all lipemic samples were highly significant (P less than 0.0001) and the SD of the control values around the regression lines were small compared with the mean value for an assay. The technique was simple, quick, and inexpensive. With proper validation, reliable predictions of true serum values could be calculated for lipemic serum samples for all assays studied.

Esophageal healing was evaluated in 10 ponies after sutured and nonsutured cervical esophagotomy techniques. Mucosal healing occurred significantly (P less than 0.005) faster after sutured esophagotomies (x = 7.5 days after surgery) than after nonsutured esophagotomies (x = 25.6 days after surgery), based on endoscopic and clinical evaluations. Although endoscopy was an accurate assessment of the return of normal passage of a food bolus through the esophagus, 4 of 10 ponies had radiographic evidence of a sinus tract after the mucosa was considered healed, based on endoscopic and clinical examinations. The surgical skin wound also healed significantly sooner after sutured esophagotomies (x = 10 days) than after nonsutured esophagotomies (x = 33.4 days). A traction diverticulum developed in all ponies with nonsutured esophagotomies, but occurred in only 1 pony with sutured esophagotomy. Minor complications were seen more frequently with sutured esophagotomy than with a nonsutured esophagotomy, but were resolved with local therapy. Saliva appeared to inhibit wound healing. All ponies were fed through esophagostomy tubes until the mucosa at the esophagotomy site was considered healed. Except for 1 sutured esophagotomy that dehisced, sutured esophagotomy was superior to nonsutured esophagotomy, because earlier establishment of a mucosal seal resulted in more rapid healing and reduced nursing care.
