Two-port laparoscopic ovariectomy (Lap-OVE) has been performed in small dogs, using 3-mm and 5-mm portal sites, and is associated with reduced surgical stress and postoperative pain. However, extension of the incision is often needed to extract the ovaries. In this study, we aimed to minimize invasiveness by using smaller-sized cannulas as well as a novel technique for ovary extraction. Lap-OVE was performed on six, healthy female dogs (range, 3 to 7.2 kg) using two 3-mm midline portals. The middle finger of a size M nitrile glove was cut at its base and sterilized preoperatively. The ovary was suspended at the body wall using a 1-0 blue nylon needle, and the ovarian pedicle and ligaments were transected using a 3-mm bipolar forceps. To facilitate the glove passing through the 3.9-mm port, it was turned inside out to expose the smooth inner surface, before being inserted into the abdominal cavity with an applicator. Both ovaries were placed inside, and the mouth of the glove was exteriorized through the port with a laparoscopic grasping forceps. The ovaries were morcellated inside the glove, using Adison-Brown tissue forceps and iris scissors, which enabled safe extraction without incision enlargement. Median incision lengths were 4.3 mm (3.5-mm cranial cannula) and 4.8 mm (3.9-mm caudal cannula). An advantage of this procedure was that there was no need for skin sutures. In conclusion, using our novel technique, sutureless Lap-OVE was possible in small dogs using two 3-mm portal sites without additional incision.

Percutaneous extracorporeal life support (P-ECLS) is a useful modality for the management of refractory cardiac or pulmonary failure. However, venoarterial P-ECLS may result in a complication of left ventricular distension. In this case report, we discuss a patient with drug-induced dilated cardiomyopathy managed with venoarterial P-ECLS and a left atrial vent catheter. The venoarterial P-ECLS was modified to a paracorporeal left ventricular assist device (LVAD) by removing the femoral venous cannula. After 28 days of hospitalization, the patient was successfully weaned from the paracorporeal LVAD and discharged home from the hospital.

We propose a safe, simple, and novel method to harvest fat using a standard liposuction cannula and a Redivac or alternative closed-suction drain. The authors have used this technique for both 'dry' and 'wet' liposuction. This technique is both easy to perform and cost-effective whilst providing both a silent and relatively atraumatic fat harvest. The lower negative pressure compared with traditional harvesting systems likely preserves fat integrity for lipofilling. This method maximises resources already held within a hospital environment.

Aneurysm of the Aorta is a grave disease mostly producing disabling symptoms and ultimate death by rupture and hemorrhage without surgical intervention. The author recently experienced one case of surgical correction of descending thoracic aortic aneurysm treated with excision of the aneurysm and replacement of Dacron artificial vessel under temporary external by pass technique in November, 10th, 1975. 9mm internal diameter arterial cannula was inserted into upper and below the aneurysm. Bypass time was about 1 hour. The case was 35 years old women who had small egg sized saccular aneurysm in the upper third of the descending thoracic aorta involving the 1t. subclavian artery. Histopathological diagnosis was arteriosclerotic. Immediate postoperative course had been uneventful except low pressure and pulse of the left arm. The follow-up was possible up to date about 3 months. The patient has been doing well with ordinary activities except mild left chest discomfort.

Clinical symptoms of stroke patients vary widely, and include headache, dizziness, vomiting, dysphagia, dysphasia, incontinence, confusion, chest discomfort, dyspnea etc. Stroke patients who had chronic respiratory disease or had tracheostomy cannula usually have high levels of sputum, but there have been rare clinical reports about treatment of oriental medicine. High levels of sputum in stroke patients can cause pneumonia and dyspnea, and so can delay rehabilitation. By use of Haepyoleejin-tang.Jungchun-tang with change of Ephedrae Herba capacity, we could improve sputum secretion and respiratory function of two stroke patients, and so we report on the clinical course of two stroke patients with high levels of sputum.

This paper describes to design and to examine the mechanical characteristics of high frequency jet ventilator. The device consists of Phase lock loop(PLL) system, solenoid valve driving control part and Air regulating system. This study is carried out by changing several factors such as endotracheal tube(E.T. tube)diameter, injector cannula diameter, 1%, and frequency(breaths/mim.) having direct effects on the gas exchange as well as parameters of the entrained gas by venturi effects, so as to measure the tidal volume and minute volume. This system characteristics were as follows : 1) Frequency : 6-594bpm 2) Inspiration time : 1-99% 3) Variance of input air pressure : 1-30PSI.

This experiment was performed to estimate the changes on blood flow of the oral structures in hemorrhagic shock. Rabbits were anesthetized by intravenous injection of nembutal(30mg/kg). The Femoral artery was exposed and cannulated with polyethylene tubing filled with heparinized saline. Hypovolemic shock was induced by collecting the bloos of which amount was equaled as 2 % of body weight through arterial cannula for about 30 minutes. During hemorrhage, arterial blood pressure was recorded on recorder. In hypovolemic shock, arterial blood pressure decreased from 116.2±4.1 mmHg to 62.6±4.0 mmHg. Distribution of blood flow in oral tissues decreased to 30-50 % of control group. But blood flow of the masseter muscle was increased and the mandibular angle was not changed.

The cervical esophageal stricture has various surgical modalities and difficulties in reconstruction. We had experienced a case of successful reconstruction of the cervical esophageal restenosis using the free jejunal graft, on 30 year old man had had esophageal stricture after ingestion of lye. He had undergone colon interposition[esophagocologastrostomy] with left colon feeding gastrostomy. But restenosis was occurred just above of the cervical esophagocolostomy site several times of balloon dilatation were failed. So, we decided to use of the free jejunal graft. The free jejunal graft was isolated about 15cm length with it`s vascular arcades. The graft was irrigated with the mixed solution as isotonic saline, heparin and papaverine chloride. The artery of graft was anastomosed to the branch of the external carotid artery in end to side with continuous sutures of the 8.0 Prolene. The vein of the graft was anastomosed to the branch of the anterior facial vein in end to end with continuous sutures of the 8.0 prolene. Postoperative course was uneventful and the patient was discharged after removal of the tracheostomy cannula and gastrostomy tube.

The incidence of syphilitic aortic aneurysm was decreased now a day. The predilection site of cardiovascular syphilis is the thoracic aorta, especially ascending portion. The form of syphilitic aneurysm is characterized by saccular or fusiform. We have experienced 58 year old female complained of intermittent left chest pain for these 2 years. Saccular aneurysm of 7 cm in diameter at the descending thoracic aorta just distal to the left subclavian artery was confirmed with aortogram, and etiologic lesion was suspected as syphilis by her strong positive finding of serum VDRL test. Excision of the aneurysm was done under temporary bypass with heparinized 10mm silicone bypass cannula, and 23 mm Dacron aortic prosthetic graft in 10 cm segment was replaced, and excised aortic segment was confirmed as syphilitic aneurysm on light microscopic examination. Postoperative hospital course was uneventful, and discharged 3 weeks after operation in good normotensive condition. The patient died of CVA 3 months after discharge at home.

37 years old female was admitted with chief complaints of dyspnea on exertion and hemoptysis. Past history and family history were non-contributory. Physical examination showed Grade III systolic murmur at the apex, which transmitted to the back. E. K. G. and X-ray findings were compatible with the mitral insufficiency. With small size of Beall mitral valve, mitral valve replacement was done under the cardia-pulmonary bypass using hemodilution technic. Patient was tracheotomized after operation and assisted respiration was done for four weeks. Postoperatively, all signs were fine and patient walked around the ward without any difficulty, but she was in psychotic state. On postoperative 60th day, she complained of sudden dyspnea and on chest film, tracheal stenosis was found and recannulation of the tracheal tube was made. Thereafter, she was quite fine until postoperative 110th day when she, by berself, removed the tracheal cannula and died of asphyxia. Autopsy findings of the valve showed no thrombosis, no variance of the valve, and good endothelization of the valve cuffs. Asphyxia, due to removal of the tracheal connula by herself under psychotic state, was considered to be the cause of death in this patient who had tracheal stenosis after tracheostomy.
