Abstract
Leakage after oesophageal anastomosis or perforation remains a challenge for the surgeon. Traditional management has been operative repair or intensive conservative management. Both treatments are associated with prolonged hospitalisation and high morbidity and mortality rates. Self-expanding metallic stents have played an important role in the palliation of malignant oesophageal strictures and the treatment of tracheoesophageal fistulae. However, self-expanding metal stents in benign oesophageal disease are associated with complications such as bleeding, food bolus impaction, stent migration, and difficulty in retrieval. The Polyflex stent is the only commercially available self-expanding plastic stent which has been used in the management of malignant oesophageal strictures with good results. This review will consider the literature concerning the use of self-expanding plastic stents in the treatment of oesophageal anastomotic leakage and spontaneous perforations of the oesophagus.

Abstract
BACKGROUND This retrospective single-institution study presents a successful treatment strategy for Boerhaave's syndrome. METHODS During 1995-2008, 15 patients with spontaneous esophageal perforation were treated. Patients were grouped according to time from symptoms to referral (early, <24 h; late, >24 h). In group I (early, n = 8 patients) treatment comprised primary surgical esophageal repair in seven cases and endoscopic clipping in one case. In group II (late, n = 7 patients) treatment comprised esophagectomy without primary reconstruction (4 cases) or controlled esophagocutaneous fistula (3 cases). Measures of outcome included age (years), delay to diagnosis (h), severe sepsis on admission, mortality, and hospital and intensive care unit (ICU) stay. RESULTS The overall hospital mortality rate was 6.6% (1/15), being 0% (0/8) in group I and 14.2% (1/7) in group II. Patient age (49.6 vs. 68.6 years, P < 0.0001), delay to diagnosis (17.75 vs. 69 h, P < 0.0001), severe sepsis on admission (0 vs. 4, P = 0.0256), and ICU stay (4 vs. 14 days, P = 0.006) were all greater in group II. CONCLUSIONS Early diagnosis and carefully selected therapeutic tactics can reduce the mortality rate of Boerhaave's syndrome to an acceptably low level. Methods of organ preservation and minimally invasive techniques can be applied successfully in the treatment.

Abstract
BACKGROUND Surgeons have not typically utilized an endoscopic approach for diagnosis and management of acute oesophageal perforation, mainly due to fears of increased mediastinal contamination. This study assessed the evolution of endoscopic approaches and their effect on outcomes over time in acute oesophageal perforation. METHODS All patients with documented acute oesophageal perforation between 1990 and 2009 were enrolled prospectively in an Institutional Review Board-approved database. RESULTS Of 81 patients who presented during the study period, 52 had upper gastrointestinal endoscopy for diagnosis alone (12 patients; 23 per cent) or as a component of acute management (40 patients; 77 per cent). Use of endoscopy increased from four of 13 patients in the first 5 years of the study to 20 of 24 patients in the final 5 years. Endoscopy was used in conjunction with surgery in 28 patients, of whom 21 underwent primary repair, three had resection, and one a diversion; 12 patients in this group had hybrid operations (combination of surgical and endoscopic management). Primary endoscopic treatment was used in 15 patients (29 per cent), most commonly involving stent placement (7). Of those having endoscopy, complication rates improved (from 3 of 4 to 8 of 20 patients), as did mean length of stay (from 21·8 to 13·4 days) between the initial and final 5 years of the study. There were two deaths (4 per cent). Of 21 patients who had both endoscopic assessment and management in the operating room, endoscopy identified additional pathology in ten, leading to a change in management plan in five patients. CONCLUSION Endoscopy is a safe and important component of the management of acute oesophageal perforation. It provides additional information that modifies treatment, and its wider use should result in improved outcomes.

Abstract
INTRODUCTION The management of esophageal perforations and leaks remains a challenge. Although there are broad management principles, each situation may require a different surgical approach. The aim of this report was to describe the management of these esophageal crises by transluminal drainage via a transabdominal approach. METHODS Between 2005 and 2009, patients with anastomotic or gastric staple line leak (n = 4) or esophageal perforation (n = 2) underwent transabdominal surgery and transluminal drainage. This simple technique has, to the best of our knowledge, not been previously reported. RESULTS All six patients survived. The median intensive care unit and hospital stays were 12 days (range 0-32) and 63 days (range 32-99), respectively. At a median follow-up time of 25 months (range 15-60), five of the six patients remain alive and well. One patient with node positive esophageal carcinoma has died from relapsed disease. CONCLUSIONS Transabdominal transluminal drainage should be added to the list of potential techniques that can be employed in management of esophageal leaks and perforations. It is a valuable adjunct to the armamentarium of the esophageal surgeon for dealing with these challenging situations.

Abstract
BACKGROUND Boerhaave's syndrome has a high mortality rate (14-40%). Surgical treatment varies from a minimal approach consisting of adequate debridement with drainage of the mediastinum and pleural cavity to esophageal resection. This study compared the results between a previously preferred open minimal approach and a video-assisted thoracoscopic surgery (VATS) procedure currently considered the method of choice. METHODS In this study, 12 consecutive patients treated with a historical nonresectional drainage approach (1985-2001) were compared with 12 consecutive patients treated prospectively after the introduction of VATS during the period 2002-2009. Baseline characteristics were equally distributed between the two groups. RESULTS In the prospective group, 2 of the 12 patients had the VATS procedure converted to an open thoracotomy, and 2 additional patients were treated by open surgery. In the prospective group, 8 patients experienced postoperative complications compared with all 12 patients in the historical control group. Four patients (17%), two in each group, underwent reoperation. Six patients, three in each group, were readmitted to the hospital. The overall in-hospital mortality was 8% (1 patient in each group), which compares favorably with other reports (7-27%) based on drainage alone. CONCLUSIONS Adequate surgical debridement with drainage of the mediastinum and pleural cavity resulted in a low mortality rate. The results for VATS in this relatively small series were comparable with those for an open thoracotomy.

Abstract
Perforation of esophagus in the adult is a very morbid condition with high morbidity and mortality. The ideal treatment is controversial. The main causes for esophageal perforation in adults are iatrogenic, traumatic, spontaneous and foreign bodies. The morbidity and mortality rate is directly related to the delay in diagnosis and initiation of optimum treatment. The reported mortality from treated esophageal perforation is 10% to 25%, when therapy is initiated within 24 hours of perforation, but it could rise up to 40% to 60% when the treatment is delayed beyond 48 hours. Primary closure of the perforation site and wide drainage of the mediastinum is recommended if perforation is detected in less than 24 hours. Treatment option for delayed or missed rupture of esophagus is not very clear and is controversial. Recently a substantial number of patients with esophageal perforation are being managed by nonoperative measures. Patients with small perforations and minimal extraesophageal involvement may be better managed by nonoperative treatment Major prognostic factors determining mortality are the etiology and site of the injury, the presence of underlying esophageal pathology, the delay in diagnosis and the method of treatment. For optimum outcome for management of esophageal perforations in adults a multidisciplinary approach is needed.

Abstract
BACKGROUND Spontaneous rupture of the esophagus (Boerhaave's syndrome) is a rare, well-defined clinical syndrome caused by a longitudinal perforation of the esophagus. It is a life-threatening condition that necessitates rapid diagnosis and treatment. Patients typically present acutely with a history of vomiting followed by chest or abdominal pain. However, the diagnosis may be difficult or missed when patients present with chronic symptoms that mimic other conditions. CASE PRESENTATION In this report, we present a unique case of Boerhaave's syndrome in a 53-year-old male patient. In contrast to the more common acute presentation, our patient developed non-specific symptoms in association with an intrathoracic cyst. In this report, we will also review the usual presenting signs, symptoms, and treatment of Boerhaave's syndrome. CONCLUSION Our emphasis in this paper will be on the importance of recognizing and diagnosing Boerhaave's syndrome in an acute as well as a chronic state.

Abstract
Chest pain is one of the most frequently seen chief complaints in patients presenting to emergency departments, and is considered to be a "high-risk" chief complaint. The differential diagnosis for chest pain is broad, and potential causes range from the benign to the immediately life-threatening. Although many (if not most) emergency department patients with chest pain do not have an immediately life-threatening condition, correct diagnoses can be difficult to make, incorrect diagnoses may lead to catastrophic therapies, and failure to make a timely diagnosis may contribute to significant morbidity and mortality. Several atraumatic "high-risk" causes of chest pain are discussed in this article, including myocardial infarction and ischemia, thoracic aortic dissection, and pulmonary embolism. Also included are brief discussions of tension pneumothorax, esophageal perforation, and cardiac tamponade.

Abstract
BACKGROUND Esophageal perforations and extensive anastomotic leaks after esophageal resection or gastrectomy are surgical emergencies with high mortality rates. In recent years, the use of self-expanding metallic stents (SEMS) has emerged as a promising treatment alternative for bridging and sealing the damage. This study aimed to evaluate the role of covered SEMS for the management of esophageal perforations and anastomotic leaks. METHODS All esophageal stent placement procedures (174 procedures for 157 patients) at the authors' unit between January 1999 and April 2008 were assessed by a retrospective chart review. Of the 157 patients, 10 (6.4%) were treated with SEMS for sealing of an iatrogenic esophageal perforation (n = 4), a spontaneous esophageal rupture in Boerhaave's syndrome (n = 4), or an anastomotic leakage (n = 2). RESULTS The median time from perforation or anastomotic leak to stent insertion was 13 days (range, 2 h to 48 days). The esophageal leak was totally sealed for 8 (80%) of 10 patients. The overall mortality rate was 50% (n = 5), and three (30%) of the five deaths were related to the perforation (n = 2) or leakage (n = 1). In both of the perforation cases, the diagnosis and treatment were substantially delayed. One patient with an anastomotic leak after gastrectomy died of the complication despite successful operative and SEMS treatment. Two of the deaths were unrelated to the perforation. In both cases, the cause of death was a disseminated malignant disease. CONCLUSIONS Traumatic perforations and anastomotic leaks can be treated effectively with covered SEMS together with adequate drainage of the thoracic cavity even in cases of severely ill patients with inveterate esophageal perforations and leaks.

Abstract
Esophageal perforation is uncommon and traditionally has a high rate of morbidity and mortality. Our aim was to perform a 13-year retrospective review of the cases managed in our district general hospital. Thirty-four cases of esophageal perforation diagnosed between 1995 and 2008 were retrospectively analyzed. There were 20 males and 14 females with a median age of 64 (range 23-86) years. The etiology of the perforations were Boerhaave's syndrome (n= 19), therapeutic endoscopy (n= 9), diagnostic endoscopy (n= 2), gastric lavage injury (n= 1), foreign body (n= 1), blunt chest trauma (n= 1), and spontaneous tumor perforation (n= 1). Only 11 cases (32%) had evidence of surgical emphysema upon examination. In 50% of cases, another clinical diagnosis was initially suspected. Twenty-four were treated surgically and 10 cases managed non-operatively. Surgical treatment included thoracotomy with primary repair (n= 9), T-tube drainage (n= 7), emergency esophagectomy (n= 1), or intra-operative stent insertion (n= 1). Four cases had primary repair and fundal wrap via abdominal approach without thoracotomy. Two patients were treated with washout and drainage only. Eight patients died overall (in-hospital mortality 23.5%). Esophageal perforations are often initially misdiagnosed and the majority do not have surgical emphysema. There are a wide variety of methods to manage esophageal perforation. Management tailored to the location and size of perforation, degree of contamination, and underlying cause appears to result in a reasonable prognosis.

Abstract
OBJECTIVE To identify Th1 cell-stimulating antigens/peptides encoded by the genes predicted in the Mycobacterium tuberculosis-specific genomic region of difference (RD)1, deleted in Mycobacterium bovis Bacille Calmette-Guérin(BCG), by using synthetic peptides and whole blood from tuberculosis (TB) patients. MATERIALS AND METHODS Heparinized peripheral blood was obtained from culture-proven pulmonary TB patients (n = 16) attending the Chest Disease Hospital, Kuwait. Whole blood was diluted with tissue culture medium RPMI-1640 and tested for Th1 cell stimulation using antigen-induced proliferation and interferon-gamma (IFN-gamma) secretion assays. The antigens included a peptide pool of 220 peptides covering the sequence of 12 open reading frames (ORFs) of RD1 (RD1(mix)), peptide pools of RD1 ORF5 (ORF5(mix)), ORF6 (ORF6(mix)) and ORF7 (ORF7(mix)), and individual peptides of ORF6 (P6.1-P6.6) and ORF7 (P7.1-P7.6). M. tuberculosis culture filtrate, cell walls and whole-cell M. bovis BCG were used as complex mycobacterial antigens. The results obtained with different antigens and peptides were statistically analyzed for significant differences using Z test. RESULTS The complex mycobacterial antigens (culture filtrate, cell walls and M.bovis BCG) and RD1(mix) induced comparable (p > 0.05) positive antigen-induced proliferation and IFN-gamma responses with whole blood from TB patients. However, the positive IFN-gamma responses induced by ORF6(mix) and ORF7(mix) were higher than ORF5(mix). Among the individual peptides, P6.4 and P7.1 of ORF6 and ORF7, respectively, induced the highest IFN-gamma responses, suggesting that these peptides represented the immunodominant Th1 cell epitopes of RD1 ORF6 and ORF7 in the patients tested. CONCLUSION The whole blood assays with synthetic peptides are useful to identify Th1 cell antigens/peptides encoded by genes located in M. tuberculosis-specific genomic regions.
