A 10-months-old cross long hair cat named Casper with clinical symptom of vomiting mixed with slimy cat feed was referred to Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Bogor Agricultural University to endoscopy examination and therapy. The owner believed that Casper ate a 5 cm long sewing needle a few days earlier. The history and physical examination were examined at DNA Clinic with symptoms of lack of appetite and becoming quieter and calmer. Radiogram showed the needle was in thorax area with a vertical needle penetrating the esophageal wall. Removal of the needle and observation of the esophagus area were done using endoscopy under general anesthesia. Using endoscopy, it was known that the needle was swallowed along with the sewing thread with position of all needles penetrating the esophagus wall and leaving a small amount of thread on the lumen. The needle was pulled back to the esophageal lumen by pulling the remaining thread and then both needle and the thread were pulled back out using an alligator grasping forceps that used through working channel. Therapy given after endoscopy was antibiotics and anti-emetics.

General anaesthesia has a high risk during surgery, regional anaesthesia with nerve block is expected to minimize the use of general anaesthesia while increase the analgesic effect and muscle relaxation effect. This study aimed to compare the analgesic effects of sciatic nerve block on the hind limb and the effect of lidocaine 2%, and a combination of 2% lidocaine with 2% xylazine on sheep cardiopulmonary function. Sciatic nerve block was guided with ultrasonography and nerve stimulator. In this research, sheep were sedated with diazepam (0.5 mg / kg). Sheep  was divided into three groups; first injected with saline solution (SS), second with lidocaine 2% 5 mg / kg (Lid) and third with lidocaine 2% 5 mg / kg and xylazine 2% 0.1 mg / kg (LidXyl). The results of this research showed that the LidXyl group had the highest analgesic effect and broader blockade area, namely femoris, cruris, and metatarsus-digit. The LidXyl blockade value was highest in the digitmetatarsus region, while the Lid group shows the highest blockade value in the cruris region. The LidXyl group with the addition of xylazine results in a decrease in heart rate and respiration rate. Xylazine increased and extended analgesic effect compared to lidocaine but resulted in a decrease in heart rate and respiration rate in the early minutes of anaesthesia, it is however safe to be used in sheep.
