Besides gastric pull-up or colonic interposition, microvascular technique in esophageal reconstruction has been approved reliable methods. When free intestinal transfer is considered, jejunal free flap is commonly used. We treated the patient who had undergone reconstruction with a right colon interposition and suffered from inability of swallowing because of stricture and necrosis of the interposed flap. Although we have planned jejunal free transfer, we couldn't use jejunum due to adhesion by previous gastrojejunostomy and colon interposition. Salvage procedure with microvascualr free left colon flap was executed successfully. After 9 month follow-up, the patient was able to consume a normal diet.

Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract and characterized by relapsing and remitting episodes, with progression over time to complications of stricture, fistulas, or abscesses. The etiology is unknown, although the common opinion is that the disease arises from a disordered immune response to the gut contents in genetically predisposed individuals. Infliximab is a mouse-human chimeric antibody against tumor necrosis factor ${\alpha}$, and has proven to be effective in active Crohn's disease for both induction and maintenance therapy. Despite the growing experience with infliximab in Crohn's disease, optimal treatment strategies still need to be determined. The purpose of this review is to summarize the current knowledge on the use of infliximab in Crohn's disease and to discuss the yet-unsolved issues.

This study is the basic research on esophageal balloon dialation with automatic detection of the pressure change in the balloon and analysis using personal computer. In conventional method, the esophageal stricture is cured by surgically. Recently, balloon dialation method has been proposed and is popularized. In balloon dialation, detecting esophageal rupture is very important. When using radiological investigation, the leak of contrast medium is very dangerous. In proposed method, the detection of esopageal rupture can be peformed by detecting and analyze the pressure change of dialation balloon. Experimental system is composed of balloon catheter, pressure pump, pressure sensor, A/D converter and PC.

Two patients with chronic Budd-Chiari syndrome resulting from segmental obstruction of the inferior vena cava underwent operation. There were 1 man and 1 woman. The obstructed segment was directly visualized by a transthoracic, transdiaphragmatic, retroperitoneal approach. In these two cases, severe segmental obstruction of the inferior vena cava was observed just above the right hepatic vein. These patients underwent successful retrohepatic cavoatrial bypass with a polytetrafloroethylene [PTFE] graft [ 16mm plain and 16mm ringed graft ]. There were no operative mortality and postoperative complication. These patients have been followed up for 6months and 36months without evidence of re-obstruction. When there is a severe stricture of the IVC with hepatic veins draining freely into the obstructed segment of the IVC, a dorsal cavoatrial bypass with a PTFE graft, preferably ringed, is the method of choice.

In the treatment of the acute respiratory failure, ventilatory support with endotracheal intubation or tracheostomy is a life saving procedure in many cases but the development of postintubation tracheal stenosis is a very serious complication. Recently we have experienced one case of postintubation tracheal stenosis which occurred in the region of cuff site. Preoperative tracheogram showed a concentric stricture 3.0 cm in length located 4.0 cm proximal to the carina. Under the general anesthesia, the stenotic segment was resected and end-to-end anastomosis was performed successfully through the right posterolateral thoractomy. Her postoperative course was uneventful and the patient has remained well till now.

This is a report on four cases of bypass for esophageal stricture due to gastro-esophageal carcinoma in the Department of Thoracic Surgery, Chonnam University Hospital. Bypass was performed intrathoracal esophago-jejunostomy by a segment of jejunum. Three patients received end to end anastomosis and the other one side to end esophagojejunostomy. Postoperative results were as follow; There was no swallowing disturbance with regular diet and the patients appear to be more comfortable by bypass than gastrostomy or jejunostomy. Postoperative condition of all the patients was satisfactory because other organs were intact. However, two patients expired in 12 months and 6 months after operation by wide metastasis and the other 2 cases are living now with regular diet in 4 months and 2 months after operation.

Gastro-esophageal reflux disease (GERD) is a recurrent, long-term gastrointestinal condition characterised by the abnormal reflux of stomach contents into the esophagus. Heartburn is the most dominant symptom, which can be life long and can considerably reduce quality of life. The main goals of treatment are to alleviate symptoms and prevent relapses, esophageal stricture and adenocarcinoma. This paper presents a review comparing the effectiveness of omeprazole with Nissen fundoplication surgery for the treatment of GERD. Nissen fundoplication is more effective in controlling heartburn symptoms, healing esophagitis and preventing relapses than omeprazole. Quality of life, in terms of productivity and ability to work, is difficult to assess in the omeprazole group and, as a result, a comparison of this aspect is limited. Although fundoplication is expensive in the short term, it is more cost-effective than omeprazole. Nurses need to be aware of the effectiveness of omeprazole and fundoplication to provide patients with accurate information, which assists patients in decision making regarding treatment options.

Background and Objectives : The aim of the this study is to determine the efficacy of an external prosthesis made of ringed Polytetrafluoroethylene to prevent Postanastomotic stenosis after surgical correction of extensive tracheal defects in rabbits. Materials and Methods : Thirty rabbits were used, divided into two groups of 15 animals each. Group A rabbits underwent resection of six-ring segments of the cervical trachea and tracheal end-to-end anastomosis. The Procedure used in group B was similar to that used in group A. but the tracheal anastomosis was supported by an external ringed polytetrafluoroethylene prosthesis. After six months, rabbits were killed and tracheas were resected and then compared the postanastomotic tracheal stenosis using morphometry. Results : Anteroposterior diameter, transverse diameter, cross sectional area and intra luminal perimeter of trachea was greater in group B than group A. Also inflammatory changes of mucosa and submucosa were greater in group A than group B. Conclusion : A ringed PTFE as a external stent was effective to prevent tracheal stenosis resulting from the extensive tracheal resection and tracheal reconstruction in rabbits.
