Fibrovascular polyp of the esophagus in infant

A five month female was referred complaining of intermittent vomiting with protrusion of a sausage-like mass through the oral cavity. Esophageal endoscopy and esophagogram revealed a mass in the upper esophagus, which was diagnosed as a fibrovascular polyp. Under general anesthesia, the mass was grasped through the oral cavity with a forcep and ligated and excised at the base, where a stump arose from the posterior wall of the cervical esophagus. The pathology was confirmed as a fibrovascular polyp, which is a rare benign esophageal lesion occurring mostly in adult males, and has not been reported in infancy.

Two Modified T2 Sympathicotomies in Palmar Hyperhidrosis / 대한흉부외과학회지

BACKGROUND: Thoracoscopic T2 sympathicotomy had been performed as a simple and effective method in treating palmar hyperhidrosis, however, this method had the complications of compensatory hyperhidrosis and facial anhidrosis. Therefore, a more limited and modified methods for T2 sympathicotomies were introduced and comparative analysis of the modified upper and lower T2 sympathicotomy were made in the treatment of palmar hyperhidrosis. MATERIAL AND METHOD: From January 1997 to December 1998, 41 patients with palmar hyperhidrosis had been treated by modified T2 sympathicotomy at the Kon-Kuk University Seoul Hospital. Twenty-four patients underwent a modified upper T2 sympathicotomy(Group A), and seventeen patients underwent a modified lower sympathicotomy(Group B). A comparison between groups A and B were made according to the medical records and interview results. RESULT: All patients showed symptomatic improvements after the operation. The anisocoria, facial anhidrosis and dissatisfaction for compensatory hyperhidrosis were more common in Group A and the individual satisfaction for the operations were higher in Group B. CONCLUSION: The modified lower T2 sympathicotomy might be a more effective and less complicated method than the modified upper T2 sympathicotomy.

Single Lung Transplantation in Pulmonary Fibrosis Patients / 대한이식학회지

A lung transplantation in the case of idiopathic pulmonary fibrosis was performed on July 7th, 1996 by the department of Thoracic Surgery, Yonsei University Medical College. The 52 year-old male patient (having a past history of cholecystectomy, 6 years ago) suffering from severe dyspnea, progressively aggravating for last five years. On physical examinations, two surgical scars were found in his left chest wall and upper abdominal area and wheezing was auscultated in both lung fields. The pulmonary function test performed in march, 1996, revealed FVC of 1940 ml (51%) and FEV1 of 1680 ml/min (58%) and the arterial blood gas study showed pH 7.4 PaO2 43.2 mmHg, PaCO2 35.0 mmHg (room air), pH 7.4 PaO2 89.8 mmHg, PaCO2 40.8 mmHg (mask 5l/min). Through the coronary angiography, moderate degree of pulmonary hypertension and 50% stenosis of left anterior descending branch of his coronary arteries were detected. The right lung from 17 year old male under brain death was removed through a median sternotomy incision and immersed in 70 ml/Kg of preservation solution (modified Euro-collins). Preparing the recipient, the pulmonary artery was dissected and temporally ligated for 15minutes, after then, an arterial blood gas study was taken to reveal pH 6.97, PaO2 221 mmHg, PaCO2 126 mmHg (FiO2 1.0 PEEP 5 cm) and his pulmonary arterial pressure was 85/26 mmHg (when the systemic arterial pressure was 140/80 mmHg) that indicates the necessity of the cardiopulmonary bypass; extracorporeal circulation was initiated through the femoral artery and right atrium. Placing the donor lung in the ipsilateral thoracic cavity of the recipient, the bronchus was first anastomosed in an telescopic fashion (the smaller bronchus into the lumen of the larger one) using the prolene 4-0. The pulmonary artery was anastomosed by prolene 5-0 and the LA by prolene 4-0. The total ischemic time was 70 minutes and the bypass time was 145 minutes. For the postoperative immunosuppression, cyclosporin and immuran was used and 2 weeks of induction therapy with OKT3 was followed by steroid. No evidence of rejection was shown in the transbronchial lung biopsy, performed a week after the transplantation. Fever developed 3 month after and aspergillosis and CMV infection was suspected through the transbronchial lung biopsy; vigorous treatment was followed but the patient had expired after 82 days postoperative survival.

Animal Model for Sequential Bilateral Reimplantation of the Lung in Dog / 대한흉부외과학회지

Sequential bilateral lung transplantation may result in a variety of perioperative and postoperative complications, showing high perioperative morbidity and mortality rates. This research was performed to investigate the hemodynamic changes in adult mongrel dogs after bilateral reimplantation, two methods preferred for avoiding or minimizing graft rejection. The anterior portion of the pulmonary artery and the left atrium proximal to the superior and the inferior pulmonary veins were resected out and then re-anastomosed one hour later to prevent torsion or stenosis of the anastomotic site and the formation of a thrombosis in the left atrium. An everted suture technique was employed for the left atrium; An hour after the division, however, the main bronchus was tightly anastomosed by interrupted sutures of No. 4-0 prolene in a telescope method. A modified E-C solution mixed with PGE1 was infused into the cut portion of the pulmonary artery at the rate of 15 ml/kg/min and at a pressure of 40 cmH2O for a total dosage of 70 ml/kg in order to preserve the transected lung. Topical cooling using wet gauzes soaked with cold E-C solution was performed for one hour to prevent ischemic lung injury. The above procedures are considered to be beneficial for achieving a satisfactory outcome for bilateral lung reimplantation.

Thoracoscopic Sympathectomy for Essential Hyperhidrosis / 대한흉부외과학회지

Essential hyperhidrosis is a condition with excessive sweating, which may be localized in any part of the body. Excessive sweating has a strong negative impact on the quality of life for many persons. From June 1992 to May 1996, 211 cases of thoracoscopic thoracic sympathectomy were performed in the Department of Thoracic Surgery, Yongdong Severance Hospital, Seoul, Korea. Among the 211 cases, 192 patients had palmar hyperhidrosis, and 19 cases had facial hyperhidrosis. There were 121 males and 90 females, and the ages ranged from 10 to 67 years(average: 24.82 years old). The average operation time and the average postoperative hospital stay were 91.94 minutes and 4.31 days, respectively. Perioperative courses were uneventful, and all the patients had immediate and complete relief of symptoms with mild compensatory sweating on the chest wall and the back. Even though a thoracoscopy has the possibility of emergency conversion to a thoracotomy and technical difficulties still exist, especially in patients with facial hyperhidrosis, our experience indicates that video-assisted thoracoscopic thoracic sympathectomy is a very safe and useful procedure for hyperhidrosis.

The role of omentopexy in tracheal transplantation in dogs

The major step toward successful tracheal transplantation is revascularization of the grafted trachea. There are many reports that although omentopexy is an effective method to facilitate neo-vascularization in tracheal transplantations, the procedure has not been accepted universally in the transplantation field. It remains unclear whether an omentopexy can successfully revascularize tracheal graft regardless of the length of graft. This study was undertaken to assess the usefulness of omentopexy for long-segment(more than 4 cm) tracheal allotransplantation. We have performed six tracheal transplantations with omentopexy (group A) and four tracheal transplantations without omentopexy (group B) in mongrel dogs from July 1993 to February 1995. Five mid-portion tracheal rings were removed from ten donor dogs and ten corresponding tracheal rings were removed from the ten recipient dogs. The excised tracheal rings from the donors were transplanted to the recipient tracheal-excised sites. All the recipients were given cyclosporine, azathioprine, and prednisolone for immunosuppression in the post-operative period. The histologic results of all the surviving members of group B were better than those of the group A. These findings indicate that omentopexy has a limitation, it is not a major method for graft revascularization. Therefore the length of the tracheal graft was greater than 4.0 cm, for its viability, a longer tracheal graft requires some other blood supply aside from the omentopexy.

Pulmonary leiomyoma: a case report

A 56 year old female patient was found to have a lung mass in the right upper lobe lobe during evaluation for cough and sputum. The mass had grown slightly over the past 6 months when she was admitted for an operation. Preoperative studies revealed the benign nature of the tumor, and a thoracoscopic right upper lobectomy was performed. Postoperatively, the diagnosis was histologically proven to be pulmonary leiomyoma which is a rare type of benign lung tumor.
