Background/Aims: Endoscopic vacuum therapy (EVT) can heal a variety of defects within the gastrointestinal (GI) tract via applying negative pressure, which reduces the defect size, aspirates the infected fluid, and promotes granulation tissue. Here we present our experience with EVT as it relates to both spontaneous and iatrogenic upper GI tract perforations, leaks, and fistulas. Methods: This retrospective study was conducted at four large hospital centers. All patients who underwent EVT between June 2018 and March 2021 were included. Data on multiple variables were collected, including demographics, defect size and location, number and intervals of EVT exchanges, technical success, and hospital length of stay. Student t-test and the chi-squared test were used to analyze the data. Results: Twenty patients underwent EVT. The most common defect cause was spontaneous esophageal perforation (50%). The most common defect location was the distal esophagus (55%). The success rate was 80%. Seven patients were treated with EVT as the primary closure method. The mean number of exchanges was five with a mean interval of 4.3 days between exchanges. The mean length of hospital stay was 55.8 days. Conclusions: EVT is a safe and effective initial management option for esophageal leaks and perforations.

Background: Postpneumonectomy empyema (PPE) due to bronchopleural fistula (BPF) can be a surgical challenge for surgeons. We analyzed the follow-up outcomes after performing omentopexy and thoracoplasty for the treatment of PPE with BPF after pneumonectomy. Material and Mehod: Between December 1991 and January 2006, 9 patients underwent BPF closure using an omental pedicled flap for the treatment of PPE with BPF after pneumonectomy. There were 7 males and 2 females (mean age: $45.9{\pm}9$ years). The patients were followed up for a mean of 58 months (median: 28 months, range: $6{\sim}169$). When we performed omentopexy, the surgical procedures for empyema were thoracoplasy for 8 patients and the Clagett procedure for 1 patient. Thoracoplasty was performed for the latter patient due to recurrence of empyema, Result: For the 8 patients who were treated by omentopexy and thoracoplasty, there was 1 operation-related death due to sepsis. During follow up, 1 patient, who was treated by omentopexy and a Clagett procedure, died of acute hepatitis 40 months postoperatively. The early mortality was 11.1% (8/9). Of the 8 patients, including the 1 late death patient, successful closure of the BPF were achieved in all patients (8/9) and the empyema was cured in 7 patients (7/8). Conclusion: The BPF closure using an omental pedicled flap was an effective method for treating PPE with BPF due to 75-destroyed lung, and thoracoplasty with simultaneous omentopexy was effective and safe for removing dead space if the patient was young and in a good general condition.

Background: Postpneumonectomy empyema(PPE) is an infrequent but potentially life-threatening complication. To date, various surgical efforts have been made to manage this complication. We reviewed our 20-year surgical experience of PPE and long-term follow-up data. Material and Method: Total of 37 patients who were treated for PPE between fan, 1980 and Jun, 2000 were included. Various clinical factors such as micro-organism, operative method and timing, presence of bronchopleural fistula(BPF), underlying disease and fate of empyema cavity were retrospectively reviewed and analyzed. Result: Majority of patients(34) underwent Eloesser operation for effective drainage. There was only one operative mortality. The causative organisms were Staphylococcus species and Pseudomonas species in 46% BPF was found in 20 cases, among which spontaneous closures took place in 4 cases. The chest wall was closed in 40%(8/20) of patients with BPF, compared to 59%(10/17) without BPF. The closure rate was statistically better in patients without BPF(p=0.006). Even though the patients with benign disease showed higher closure rate(50%) than those with lung cancer (31%), the difference was not significant(p=0.25). Conclusion: Eloesser procedure was an effective method for initial drainage of PPE cavity with low operative mortality. Given the findings of low spontaneous closure rate of BPF, aggressive approach to close the BPF is mandatory to achieve the final goal of chest wall closure. It was found that majority of patients still left their chest cavity opened, even after controlling the active inflammation of the empyema cavity. More aggnessive approach for chest wall closure is recommended in all patents with benign disease and in selective patients with lung cancer if there is no evidence of recurrence at several years after the initial operation.

A clinical study was performed on 75 cases of the esophageal cancer and benign esophageal diseases experienced at Department of thoracic & cardiovascular surgery, School of Medicine, Keimyung University during 3 year period from 1978 to 1982. Of 75 cases of the surgical esophageal diseases, there were 35 patients of the esophageal cancer. 17 patients of benign esophageal stenosis, 10 patients of esophageal perforation, 4 patients of diverticulum. 3 patients of achalasia, 2 patients of congenital T-E fistula, one of upper esophageal web, one of esophageal foreign body, one of leiomyoma and patient of hemangioma. First, esophageal carcinoma was more frequent in men than in women by a ratio of five to one, and the peak incidence occurred in the 5th to 6th decade. Dysphagia was the most common symptom in 88.6 percent of our cases. The tumor was located mostly in the middle & the lower one third [91.4%]. The histological diagnosis was made in 35 cases. The squamous cell carcinoma was the most common [82.9%] and the rest was the adenocarcinoma in the lower one third [17.1%]. Thirty-five cases were operated and resection was feasible in the twenty-five patients [71.4%] with 2 cases of hospital mortality [5.7%]. All but two of the esophageal stenosis were caused by corrosive esophagitis and ages ranged from 7 to 70 years with average age of 32 years. Corrective operations were performed on 17 patients of esophageal stenosis of whom 12 patients had esophagocologastrostomy, 3 patients esophagogastrostomy and in non-corrosive esophageal stenosis one case and esophagoplasty and another case had release of external compression. There was one complication of stenosis of the esophageal perforation were traumatic in five cases, empyema in three cases, caustics in one case and postemetic in one case. 10 patients of the esophageal perforation underwent operation: primary closure in 5 cases, two staged colon interposition in 2, esophagogastrostomy in 1 and closed thoracotomy in 2 cases There were 2 complications of leakage of anastomosis sites in postoperative period. 4 patients of traction type of diverticulum underwent diverticulectomy & 3 patients of achalasia underwent modified Heller`s operation. 2 patients of congenital esophageal atresia had distal tracheoesophageal fistula & underwent one staged operation with the results of one death caused by pneumonia. Upper esophageal web had divulsion through the esophagoscope and foreign body in upper esophagus was removed through cervical esophagotomy. One case of leiomyoma in esophagus had esophagectomy and reconstruction with right colon. And one case of hemangioma in esophagus had esophagectomy & esophagogastrostomy.

Purpose: To report the successful results of using chin bone graft and autogenous tooth bone graft material (AutoBT) in alveolar cleft patients. Materials and Methods: Five patients with alveolar cleft defects underwent alveolar bone grafting. Three patients were treated using chin bone graft, and the other two patients underwent AutoBT graft. After implant site development using chin bone graft in the fi rst three cases, endosseous implant restorations were placed. In case #4 and 5, AutoBT graft material was placed to guide the normal eruption of partially impacted maxillary right canine and to the upper docking site after distraction osteogenesis. Result: Successful implant restorations with closure of the oronasal fistula were achieved in alveolar cleft defect reconstruction using either chin bone graft (Case #1, 2, 3) or AutoBT graft material (Case #4, 5). Case #4 showed enlarged follicle of the right maxillary canine, indicating a normal eruption guide pattern. Conclusion: Both chin bone graft and AutoBT graft showed favorable outcomes in reconstructing alveolar cleft defects. Autogenous tooth bone graft opens up the possibility of avoiding harvesting autogenous bone graft with complications and morbidities.

A 55-year-old male was admitted to our hospital complaining of chest discomfort, dysphagia and severe pain on swallowing. Esophageal manometry showed that there was no relaxation of lower esophageal sphincter to swallowing. There was double barrelled esophagus or mucosal stripe appearance on esophagogram. Endoscopy revealed an appearance as if an esophago-tracheal fistula had been made at the level of the upper thoracic esophagus. Also, two slit-like mucosal tears was seen on the lower esophagus. There after, fasting and total parenteral nutrition for several weeks failed to bring about any changes in his symptoms. So, as treatment, primary closure of the upper opening of the false lummen was performed under general anesthesia. Soon after the surgical procedure, the patient's symptoms were improved except for mild dysphagia. He was discharged after oral intake had been juduciously commenced with fluids and soft diet subsequently. During follow-up in out-patient department, he had no specific symptoms including fever or dysphagia and massive dissection of the esophagus was improved on esophagogram. We report the experience of a case of spontaneous submucosal dissection of the esophagus which required conservative and surgical management

1] During the period of Jan. 1959, to Aug. 1979, 47 patients of paragonimiasis have been treated in the department of Chest Surgery. 2] The total number of patients who has been admitted and treated in the department of Chest Medicine are 262 and annual distribution of number of patients has been decreased. However, since 1964, the number of patients has been stationary. On the other hand, the total number of patients who has been admitted and treated surgically in the department of Chest Surgery are 47 and the annual distribution of number of patients has not been decreased. 3] The peak age incidence lies in fourth decade [34%], and over halves of patients is in third to fifth decade. Male to female is 8.4 to 1. 4] The symptoms, which are mainly cough, chest pain, dyspnea and blood tinged sputum, developed mostly in two to five years after infestation by Paragonmius westermani. 5] Sputum tests for eggs of Paragonimus westermani were positive in 16 out of 43 patients [37%]. The 93% of patients were positive in skin test for Paragonimus westermani. The patients with negative skin test were 7%, but sputum or stool examination for Paragonimus westermani`s eggs were positive in these negative group of skin test. 6] Chest roentgenogram revealed pleural effusion [41 cases], hydropneumothorax [1 case], atelectasis [1 case] and mediastinal mass [1 case]. 7] All patients were preoperatively treated with Bithionol. The mode of surgery were decortication only [31 cases], pleuropneumonectomy [3 cases], decortication & lobectomy [2 cases], decortication & closure of bronchial fistula [1 case], thoracentesis [1 case] and postural drainage [1 case]. 8] Paragonimiasis is primarily medical disease and well treated by the administration of Bithionol. But the delayed diagnosis and missed diagnosis, especially as pulmonary tuberculosis, make the disease aggravated and chronic. Subsequently, surgical treatment is infrequently required. Chronic empyema due to Paragonimus westermani is much benign than tuberculous empyema thoracis.

Background The aims of alveolar bone grafting are closure of the fistula, stabilization of the maxillary arch, support for the roots of the teeth adjacent to the cleft on each side. We observed nostril base augmentation in patients with alveolar clefts after alveolar bone grafting. The purpose of this study was to evaluate the nostril base augmentation effect of secondary alveolar bone grafting in patients with unilateral alveolar cleft. Methods Records of 15 children with alveolar clefts who underwent secondary alveolar bone grafting with autogenous iliac cancellous bone between March of 2011 and May of 2012 were reviewed. Preoperative and postoperative worm's-eye view photographs and reconstructed three-dimensional computed tomography (CT) scans were used for photogrammetry. The depression of the nostril base and thickness of the philtrum on the cleft side were measured in comparison to the normal side. The depression of the cleft side pyriform aperture was measured in comparison to the normal side on reconstructed three-dimensional CT. Results Significant changes were seen in the nostril base (P=0.005), the philtrum length (P=0.013), and the angle (P=0.006). The CT measurements showed significant changes in the pyriform aperture (P<0.001) and the angle (P<0.001). Conclusions An alveolar bone graft not only fills the gap in the alveolar process but also augments the nostril base after surgery. In this study, only an alveolar bone graft was performed to prevent bias from other procedures. Nostril base augmentation can be achieved by performing alveolar bone grafts in children, in whom invasive methods are not advised.

A clinical analysis was performed on 118 cases of the benign esophageal diseases experienced at Department of Thoracic Surgery, Seoul National University Hospital during 20 year period from 1957 to 1976. Of 118 cases of the benign esophageal diseases, there were 84 patients of esophagenal stenosis, 14 of esophageal perforation, 8 of esophageal atresia, 7 of achalasia, 2 of hiatal hernia, 2 of esophageal foreign body and one of esophageal diverticulum. Fifty-one patients were male and sixty-seven were female, and ages ranged from one day to sixty-four years with peak incidence in the age group of 20 to 29 years. All but one of the esophageal stenosis were caused by corrosive esophagitis and ages ranged from three to sixty-four years with peak incidence in third decade. Main symptoms of the esophageal stenosis were dysphagia, weight loss and chest pain in order and mostly began between one month and one year after ingestion of corrosive agents. Corrosive esophageal stenosis developed most frequently in middle one-third of the esophagus and about one-forth of them were diffuse. Operations were performed on 72 patients of esophageal stenosis of whom 26 patients had esophagocologastrostomy, 21 gastrostomy, 20 esophagogastrostomy, 4 esophagojejunogastrostomy and 2 pharyngogastrostomy. There were 5 deaths in the postoperative period, an operative mortality of 6.9 percent, and 20 patients had one or two complications; eight were anastomotic leaks, 6 gangrenes of replaced loop, 4 wound abscesses and others. The causes of the esophageal perforation were traumatic in 7 cases, caustics in 4 and spontaneous in 3, and the most frequent site of the perforation was lower one-third of the esophagus. Frequent symptoms of the esophageal perforation were pain, fever, dysphagia and dyspnea, and preoperatively there were mediastinitis in 8 cases, empyema in 7, lung abscess in 3 and others. All 14 patients of the esophageal perforation underwent operation: primary closure in 7 cases, drainage in 4, esophagogastrostomy in 2 and 'esophageal diversion in one. There were 4 postoperative deaths and 11 postoperative complications occurred in 7 patients. The duration of symptoms in achalasia was between 3 months and 25 years, with an average duration of 6. 2 years. Frequent symptoms of the achlasia esophagi were dysphagia, regurgitation, pain and weight loss in order. All 7 patients of achlasia underwent modified Heller's operation where 2 patients had complications, restenosis in one and esophageal perforation in another. All 8 patients of congenital esophageal atresia had distal tracheoesophageal fistula and were admitted within 5 days of life, but there were pneumonic consolidation on chest X-ray in patients. Five patients underwent one staged operation with the result of 2 deaths and one anastomotic leak.
