advancement in the treatment of esophageal perforation due to the development of ICU care and antibiotics. There were controversies in the treatment of esophageal perforation when diagnosed after 24hrs. From 1995 to 2000, we performed a buttressed primary repair and mediastinal drainage in 6 Boerhaave\`s syndrome patients among 13 esophageal perforation patients. Two patients died(33%). They died because of pneumonia, ARDS and sepsis on 38th, 39th post-operative day respectively. Two patients had leak at the site of repair which was treated completely with conservative treatment. We report on the result of a buttressed primary repair and mediastinal drainage for 6 Boerhavve\`s syndrome patients.

Treatment of esophageal perforation when diagnosed late remains controversial. Ten consecutive patients since 1990 were treated late(later than 24 hours) for esophageal perforation with primary repair. Four perforations were iatrogenic, 3 were spontaneous, 2 were foreign body aspiraton and 1 was trauma. The interval from perforation to operation was 116 hours in mean and 48 hours in median value. The principles of repair included (1) a local esophagomyotomy proximal and distal to the tear to expose the mucosal defect and intact mucosa beyond, (2) debridement of the mucosal defect and closure, (3) reapproximation of the muscle, and (4) adequate drainage. The repair was buttressed with parietal pleura or pericardial fat in 9 patients. Associated distal obstruction was treated with dilation and esophagomyotomy intraoperatively. There was one mortality and cause of death was massive gastric bleeding due to gastric ulcer on 33rd day after operation. Five patients had leak at the site of repair and these cases were treated completely with conservative treatment except a mortality case. In conclusion, in the absence of malignant or irreversible distal obstruction, meticulous repair of perforated esophagus and adequate drainage are preferred approach, regardless of the duration from the injury to the operation.

Purpose: To investigate MRI findings of the repaired anterior cruciate ligament (ACL). Materials and Methods: Seventeen of arthroscopic ACL primary repair with sutures pull-out technique were followed for 21.4 months (range: 12 to 60 months). Stability was assessed with physical examination and KT-1000 arthrometer (MED metric, San Diego, CA) and postoperative MRI checked with time. The patients were divided into 2 groups according to the location of tear which was defined with the location of remained synovial sleeve. Group I (11 patients) comprised that the tear was located within proximal 1/3 of ACL substance and group II (6 patients) comprised below proximal 1/3. MRI findings of the repaired ACL were evaluated by its course, sharpness, thickness and signal intensity using 3 grade system and correlated with its location of tear. Results: In all cases, Lachman test and flexion-rotation drawer test were negative, pivot-shift test was less than grade 1 and the mean side-to-side difference by use of KT-1000 arthrometer was 1.4 mm (range: -1.0 to 2.5 mm). The overall continuity of the repaired ACL was well maintained in all cases. However, mild sagging was observed in 10 cases(58.8%), mild obscure contour in 6 cases (35.3%), increased thickness in 8 cases (47.1%) and slight increased signal intensity in 5 cases (29.5%). There was no statistical significance in all parameters between 2 groups. And a focal defect at the femoral attachment site in sagittal image was observed in 7 cases (41.2%) of all patients which comprised 2 cases (18.2%) of group I and 5 cases (83.3%) of group II. It was observed more frequently in group II with statistical significance (p=0.035). Conclusion: Some abnormal MRI findings such as mild sagged course, obscure contour, increased thickness and signal intensity, the focal defect at femoral attachment site could be observed even though the stability was well maintained clinically. We thought that the focal defect was affected by the location of tear of ACL.

Purpose: The purpose of this study is to evaluate the results of arthroscopic primary repair of a posterior cruciate ligament(PCL) avulsion injury without bony fragment at the femoral attach site. Materials and Methods: From Jan. 1993 to Dec. 2002, we performed 10 cases of PCL repair by arthroscopic suture technique. The mean follow-up period was $38.7{\pm}11$ months and the mean age of the patients was $28.2{\pm}6$ years old. 8 cases were men. 2 cases were women. At last follow-up, all cases were evaluated with the Lysholm and Gillquist knee rating system and International Knee Documentation Committee criteria. Posterior tibial displacement on stress lateral radiograph and posterior instability with posterior drawer test were measured also in all cases. Results: The mean Lysholm and Gillquist score was $94.5{\pm}2.6$. 4 cases were IKDC A(normal) and the other 6 cases were IKDC B(nearly normal). Posterior instabilities by posterior drawer test were grade I in 5 cases and grade II in 5 cases. A mean posterior translation of tibia was $3{\pm}2.3$ mm on stress lateral radiographs. Conclusion: Arthroscopic primary repair of PCL avulsion without bony fragment at the femoral attach site is one of the useful methods that reduce the posterior instability and improve the functional outcomes.

Purpose: The purpose of this article was to review the effectiveness of arthroscopic debridement and tuberoplasty, and to evaluate the clinical and radiologic results of our series for irreparable massive rotator cuff tears in the elderly. Materials and Methods: We reviewed articles that focused on the treatment options and decision making for irreparable massive rotator cuff tears. In particular, we summarized the reported results of arthroscopic debridement and tuberoplasty for irreparable massive rotator cuff tears in the elderly. Among consecutive patients who had arthroscopic tuberoplasty for irreparable massive rotator cuff tears in our series, thirty-two patients available for clinical and radiological evaluation at a mean follow-up of 29 months (range, 13-52 months) were enrolled and reviewed for the analysis. Results: At the last follow-up, the range of active forward flexion increased significantly with excellent pain relief and improvement in the ability to perform the activities of daily living. However, the group with less than 2 mm in preoperative acromiohumeral distance showed inferior postoperative results. Conclusion: Arthroscopic tuberoplasty may be an alternative option in irreparable massive rotator cuff tears for pain relief and improvement of range of motion. However, good results can not be expected if the acromiohumeral distance is less than 2 mm preoperatively and decreases postoperatively, or when the preoperative range of motion is less than $90^{\circ}$ on flexion and abduction.

Esophageal perforation is relatively uncommon but it often cause fatal if not properly treated, and it is associated with high morbidity and mortality. We report here on two cases of esophageal perforation caused by Boerhaave syndrome or pneumatic dilatation for treating achalasia. The patients were successfully treated with thoracoscopic primary repair and esophagomyotomy.

Aortoesophageal fistula induced by endoesophageal stent is rare; however, it is usually a fatal disorder, with few survivors reported. We report a case of a 32-year old female with aortoesophageal fistula after insertion of the esophageal stent in esophageal lye stricture who was successfully diagnosed with endoscopy and treated in a two-stage operation. In the first stage, we performed esophagectomy, primary repair of the fistula site in the descending thoracic aorta, and feeding gastrostomy. After the patient recovered well postoperatively, a retrosternal interposition of the right colon and cervical esophago-colo-grastostomy were performed, to re-establish the gastrointestinal tract.

A 60-year-old female entered the emergency unit with a chief complaint of hemoptysis. Based on the computer tomographic image analysis of the chest, the patient was diagnosed as having an intralobar pulmonary sequestration that accompanied a hemothorax, and the hemothorax was do to the rupture of a pseudocyst. Pulmonary lobectomy of the left lower lobe and primary closure of an aberrant artery were both performed as an emergency operation. After one week following the operation, the patient was discharged without any postoperative complications.

A left ventricular rupture might be one of the most disastrous complications after a mitral valve replacement. An acute atrioventricular groove rupture (type I) was detected in a 54-year-old female diagnosed with a mitral stenosis combined with severe tricuspid regurgitation. She had a prior medical history of an open mitral commissurotomy in Japan at 30 years ago. The surgical findings suggested that the previous procedure was not a simple commissurotomy but a commissurotomy combined with a posteromedial annuloplasty procedure. After a successful mitral valve replacement and a measured (De Vega type) tricuspid annuloplasty, the weaning from a cardiopulmonary bypass was uneventful. However, copious intraoperative bleeding from the posterior wall was detected and the cardiopulmonary bypass was restarted. Exposure of the posterior wall of the left ventricle showed bleeding from the atrioventricular groove 3 cm lateral to the left atrial auricle. Under the impression of a Type I left ventricular rupture, epicardial repair (primary repair of the Teflon felt pledgetted suture, continuous sealing suture using auto-pericardial patch and application of fibrin-sealant) was attempted. Successful local control was made and the patient recovered uneventfully. The patient was discharged at 14 postoperative days without complications. We report this successful epicardial repair of an acute type I left ventricular rupture after mitral valve replacement.
