The surgical experience on 18 patients with benign or malignant stricture of the esophagus who underwent isoperistaltic interposition of left colon from April 1989 to July 1991 was reviewed. During same period 22 esophageal reconstructions with colon were performed, but 3 patients who had intraabdominal adhesion in the left upper quadrant and one patient who had uncertainty of blood supply of left colic artery could not undergo iso-peristaltic interposition of left colon. There were 12 male and 6 female patients ranging from 16 to 65 years of age. 12 patients had corrosive esophageal stricture, two had cancer of esophagus, and another two had hypopharyngeal cancer. The postoperative complications developed in 7 patients [38.8%] and most frequently encountered complication was cervical anastomotic leakage, which was successfully managed with simple drainage in all cases but one malignant patient. There was no operative mortality. The esophageal reconstruction with isoperistaltic left colon resulted in good function in 14 patients[77.8%], fair in 3 patients[16.7], and poor in 1 patient[5.6%]. In this experience esophageal reconstruction using isoperistaltic left colon is a satisfactory method that can be accomplished with acceptable morbidity and mortality.

Pancreaticobiliary tract strictures are frequent Indications for endoscopic retrograde cholangiopancreatography(ERCP). We have investigated the brushing cytology in order to determine its efficacy for diagnosis of pancreaticobiliary malisnancies. Brushing cytology during ERCP was evaluated in 56 patients with biliary tract stricture presenting to the Catholic Hospital of Taegu-Hyosung from April 1997 to August 1999. A comparison was made between the cytologic and histologic diagnoses on 32 cases from 30 patients. A diagnosis of malignancy was establishied in 78.1%, benign in 15.6%, and inadequate in 6.3% of the cases. Statistical data on cytologic diagnoses in strictures of the bile duct were as follows; specificity and sensitivity of blushing procedure was 100% & 83.3%, respectively: sensitivity of interpretation was 89.3%: with no false positive cases and 3 false negative cases: predictive value for malignancy was 100% & 100%, respectively: predictive value for benign was 28.6% & 40%,, respectively: overall diagnostic efficiency was 84.4%. It is concluded that brush cytology is a diagnostically reliable, highly specific technique for malignant lesions encounted at ERCP, although a negative result does not rule out the diagnosis of malignancy.

L casts of Barrett's esophagus complicated with stricture is reported. A 82 years old male was undergone distal esophagectomy '||'&'||' esophagogastrostomy on suspicion of malignancy. The microscopic examination of specimen taken from the lesion revealed the "tall columnar cells" which were indicative of Barrett's esophagus, hence the diagnosis. Barrett's esophagus is a rare disease in Korea. Because of the malignant potential of the disease, surgery involving esophagectomy is often required.d.

The mucoepidermoid carcinoma of the bronchus is very rare neoplasm. The histological appearance is an intimate mixture of mucous-producing cell and epidermoid cell. The malignant potency of the tumor was determined by histologic pattern. Bronchoplasty techniques represent the ideal form of excisional therapy for benign endobronchial tumor as well as tumors of low-grade malignant potential, such as bronchial adenoma, and for repair of traumatic airway injuries and benign stricture and selected group of patients with carcinoma of the lung. We experienced a case of-low-grade mucoepidermoid carcinoma in a patient of 21-year old male who has been suffered from hemoptysis episodes for several years. The sleeve resection of left main bronchus and left lower lobectomy due to bronchiectatic change were carried out. The patient are being followed up without specific problem.

A total of 362 bile samples from 104 patients with evidence of biliary tract obstruction were submitted for diagnostic cytology from January, 1989 to April, 1991. The patients were classified based on the obstructive cause, and the cytologic results were reviewed. 298 of the specimens were from patients with intrabiliary malignant structure, and 17 were from patients with extrabiliary malignant compression or benign biliary obstruction. Bile cytology was positive for carcinoma in 42 samples from patients with intrabiliary malignant stricture, and the diagnostic sensitivity was 14%. There were no false positive cases. We concluded that the cause of low sensitivity was degenerative change of cell due to prolonged sampling time. What is noteworthy was the high prevalence of Clonorchis sinensis eggs, being detected in 25 patients with intrabiliary malignancy, supporting the association between clonorchiasis and biliary tree malignancy.

Chylothorax is a rare, but well-recognized complication of cardiothoracic surgery and operations in the region of the esophageal or aortic diaphragmatic hiatus. Especially, in nutritionally depleted patients requiring esophagectomy for benign or malignant diseases, it is a potentially life-threatening disorder that has profound respiratory, nutritional and immunologic co sequences . We have experienced a case of chylothorax after transhiatal esophagectomy in benign esophageal stricture. The diagnosis of chylothorax was confirmed after feeding through the jejunostomy tube by the change of the character of pleural effusion and high triglyceride level on the 5th postoperative day. On the thirteenth postoperative day, supradiaphragmatic thoracic duct ligation was performed through right thoracotomy. We could remove the chest tube on the 22th postoperative day, and the patient is being followed-up at out patient clinic without complications.

Over the past two years the free jejunal transfer have been used in 7 consecutive patients to restore alimentary tract continuity artier the resection of esophagus. Six patients had squamous cell carcinomas and one had esophageal stricture . The patients underwent partial esophagectomy with modified radicAl neck dissection or mediastinal Iymph node dissection. The microvascular anastomosis was performed to the neck vessels in 4 patients and to the in ercostal vessels in 3 patients. Postoperative complications were graft necrosis in one patient, and a temporary anastomotic leakage with spontaneous closure in one patient. Reconstruction of the esophagus was successful in 6 of 7 patients. We emphasize that esophagectomy followed by transplantation of a free jejunal transfer is suitable for esophageal carcinoma or intractable esophageal stricture, and involvement of the midesophagus is not a contraindication to the use of the free Jejunal transfer.

Purpose: Benign anastomotic stricture after an esophagojejunostomy using EEA stapler following a radical total gastrectomy is one of the most serious complications. The purpose of this study is to evaluate the incidence risk factors, and treatment associated with benign stricture. Materials and Methods: From March 1998 to February 2001, 436 patients underwent an esophagojejunostomy with Roux-en-Y anastomosis using an EEA stapler followed by an endoscopy. Thirty three of the 436 patients(5.5%) developed an anastomotic stricture; included 24 of the 33 patients had a benign stricture. Nine patients with a malignant stricture were excluded. Results: The median age of the 436 patients was 57 years $(23{\sim}85\;years)$. Two hundred ninety two patients were male, and 144 patients were female. The median time to diagnosing the stricture was 1.5 months $(0.5{\sim}6months)$. There was no statistical significance in any of the risk factors, including the diameter of the stapling device, the status of adjuvant treatment, the status of reflux esophagitis, and a clinical history of diabetes and hypertension. The strictured patients were treated with balloon dilatation, one to three times, with symptom relief. Conclusion: There were no statistically significant risk factors. However, further study of the vascularity of anastomoses and benign strictures needs to be considered. In the anastomotic strictured patients endoscopic balloon dilatation appeared to be the first line of treatment.

Objectives: The purpose of this study is to report bowel sound patterns recorded in 3 diseases associated with structural deformity of the pylorus-duodenum. Methods: : Bowel sound recording is a useful non-invasive tool for the evaluation of gastrointestinal motility. However, the difficulty in manual attachment of the electronic stethoscope on the abdominal wall and noise production against bowel sound signals have prohibited its widespread use. Therefore, I developed a new apparatus that eliminates the noise; it contains a sound absorbing device and a holder for the head of stethoscope. Using the new bowel sound recording system, bowel sounds of the patients were recorded repeatedly. The endoscopic and abdominal computed tomography findings were obtained from other hospitals' medical record, and all patients were confirmed to have structural deformity in the pylorus-duodenum. The records of each patient were compared and assessed. Results: : Patients had either duodenal ulcer scar, pyloric stricture, or far advanced malignant stomach cancer, as diagnosed by the gastroscopy. Their dominant frequency of bowel sound obtained from the new system was checked more than 2 times at regular intervals. All 8 recordings in the 2 patients with duodenal ulcer scar (5 times) or pyloric stricture (3 times) showed a decrease in postprandial than fasting dominant frequency. One patient with stomach cancer showed no significant change between postprandial and fasting states at 2 recordings. Conclusions: The analysis of dominant frequency in bowel sounds can indicate the existence of pyloric obstruction that could delay gastric emptying.
