Background: Many efforts were made to determine the uncommon clinical complications after lung transplantation and treatment options to tackle them; however, many of these rare complications have not been mentioned in recent publications. Evaluating and recording adverse effects after organ transplantation can significantly prevent post-transplant mortality. This study aimed to examine rejection factors by examining individuals undergoing lung transplantation surgery. Materials and Methods: In a prospective longitudinal study, we followed up on complications of 60 lung recipients post lung-transplantation surgery for six years from 2010 to 2018. All complications were recorded in follow-up visits or hospital admissions during these years. Finally, the patients' information was categorized and evaluated by designing a questionnaire. Results: From a total of 60 transplant recipients, from 2010 to 2018, 58 patients were initially enrolled in our study, but two were lost to follow-up. Uncommon complications witnessed in the post-transplantation period included endogenous endophthalmitis, herpetic keratitis, duodenal strongyloidiasis, intestinal cryptosporidiosis, myocardial infarction, diaphragm dysfunction, Chylothorax, thyroid nodule, and necrotizing pancreatitis. Conclusion: Meticulous postoperative surveillance is crucial for managing lung transplant patients for early detection and treatment of common and uncommon complications. Therefore, it is necessary to establish procedures for assessing the patients' constancy until complete recovery. [ABSTRACT FROM AUTHOR]

Background: Massive hemoptysis refers to bleeding from the sputum exceeding 100 ml/day. This condition is known to have a poor prognosis. Although foreign body aspiration is not as common as other risk factors, it may result in massive hemoptysis. In the current study, we presented a case of massive hemoptysis due to the aspiration of a toothpick. Case Presentation: The patient was a 49-year-old woman who was primarily suspected of having tuberculosis. After observing blood in the sputum, interventions, including chest computed tomography (CT) scan and conservative management, were performed. The CT scan showed no malignancy, and paraclinical investigations were negative. However, hemoptysis was progressing into an acute phase; therefore, a surgical intervention was performed for the patient. After the surgery, the cause of the lesion was found to be a toothpick. The patient was under intensive care after surgery and was discharged from the hospital in a good general condition. The morphological evaluation of the lesion showed a bronchial wall with ulceration, besides granulation tissue formation, hematoma, and fibrinoid necrosis due to foreign body aspiration into the lung, resulting in inflammatory reactions. Conclusion: In this case report, foreign body aspiration resulted in massive hemoptysis. Our primary attempts to diagnose the cause of lesion were unsuccessful, and surgery was performed due to the life-threatening condition of the patient. Overall, unexplained hemoptysis may occur following a serious accident due to foreign body aspiration. [ABSTRACT FROM AUTHOR]

Introduction: Tracheoesophageal fistula (TEF) is a rare condition, which could be life-threatening if diagnosed late or mismanaged. Post-intubation TEF is the most common form of acquired, non-malignant TEF and is usually associated with tracheal stenosis, which makes the treatment more challenging. Here, we present our experience of managing 21 patients with post-intubation TEF. Materials & Methods: Twenty one patients including seven women and fourteen men with mean age of 38.05 years, who had post-intubation TEF were managed in our center (Massih Daneshvari Hospital, Tehran, Iran) during 2004-2013. None of the patients were operated before weaning from mechanical ventilation. Single division and closure of the fistula was performed in one patient who did not have accompanying tracheal stenosis. One-stage surgical repair including tracheal resection, anastomosis, primary closure of the esophageal defect, and muscle flap Interposition was the main treatment method in all other cases. Patients were followed up for at least two years. Results: Excellent and good results achieved in 85.7% of our patients. Major complications including permanent vocal cord paralysis and recurrence of tracheal stenosis necessitating T-tube insertion occurred in two patients (9.5%). Severe cachexia and sepsis secondary to sputum retention resulted in one mortality (4.8%). Conclusion: Surgery might provide the best treatment results along with low mortality and morbidity rates in post-intubation TEFs if performed within the proper time. [ABSTRACT FROM AUTHOR]

Two patients with iatrogenic esophageal perforation following rigid esophagoscopy for foreign body removal were successfully treated with primary repair and reinforcement using a collagen patch coated with human fibrinogen and thrombin (TachoSil, Nycomed, Austria, Vienna). The clinical implication of this report is that TachoSil can be used to bolster the repair site of esophageal perforation. [ABSTRACT FROM AUTHOR]

Most authors believe that the best treatment for pulmonary hydatid disease is surgical evacuation. Although albendazole has been used prophylactically before surgery, there are many reports about increased incidence of the rupture of cyst after albendazole therapy, which can cause some complications. In this case report we present a patient with bilateral pulmonary hydatid cyst that was ruptured after using albendazole and different strategies were used for management of each cyst.

OBJECTIVES When the T-tube is inserted as a temporary stent, it is unclear whether keeping it longer in place has any benefit on the outcome. METHODS Among 1738 patients with airway stenosis (1996–2011), 134 underwent T-tube placement (mean duration = 14.3 months); temporarily while waiting for an appropriate time for surgery in 53 (Group 1), as an adjunct after a complex laryngotracheal resection in 27 (Group 2), after surgical failure in 43 (Group 3) and permanently in 11 unresectable strictures (Group 4). A logistic regression model was used for statistical analysis. RESULTS Seventy percent of patients were males (age = 33.6 ± 17 years). The main cause was postintubation/post-tracheostomy stenosis in 87% of patients. The stenosis (29.6 ± 14 mm, 5–80 mm) was located in the subglottis in 33%, trachea in 47% and both in 20% of cases. To assess the effect of T-tubes on stabilizing the airway after decannulation, 50 patients who still had a T-tube at the end of follow-up or for <1.5 months were excluded. Of the remaining 84, 31.5, 91.5 and 32.5% of patients in Groups 1, 2 and 3 were stable at least 3 months after decannulation. Moreover, 70% of those who were decannulated at or before 6 months and 53.7% of those who were decannulated after 6 months underwent another intervention (P = 0.17). The age, sex, cause, site of stenosis and even duration of T-tube insertion (P = 0.07) showed no significant effect on the decannulation outcome. CONCLUSIONS Although it seems that keeping the T-tube in place for >6 months may increase the chance of successful decannulation, it was not confirmed in our study. [ABSTRACT FROM AUTHOR]

Background: Tracheal stenosis is still a serious consequence of endotracheal intubation. Previous classification systems are commonly descriptive and are not intended to deal with management approach. The aim of this study was to present a classification system for post intubation tracheal stenosis and evaluate its efficacy in distinguishing critically ill patients who need surgical intervention. Materials and Methods: This classification system was developed based on size and type of stenosis and associated clinical signs and symptoms. Stenosis was graded based on the results of clinical examination and rigid bronchoscopy. All patients received surgical or conservative treatment based on the judgment of a surgeon experienced in management of post-intubation tracheal stenosis without considering their score. ROC curve analysis was done and cut-off point was established based on the greatest Youden index. Results: Sixty patients were studied. Resection and anastomosis were done for 49 patients. The mean score for all samples was 9.18 (range 8.77-9.45). Chosen cutoff point was 8.5 and calculated sensitivity and specificity were 89% and 42%, respectively. Positive and negative predictive values were 83.7% and 54.5%, respectively. A reasonable agreement between the estimated score and surgeon's clinical judgment (kappa=0.78) was observed. A statistically significant relationship was observed between scores greater than 8.5 and need for surgical intervention (P= 0.007). Conclusion: We presented a scoring system for post-intubation and tracheostomy tracheal stenosis using main factors influencing diagnosis and treatment and its efficacy was evaluated prospectively. It seems that this system would be capable of assimilating the treatment interventions and comparing them. [ABSTRACT FROM AUTHOR]

Aortobronchial (AB) fistula is a rare disease, which is presented with massive hemoptysis; lethal if not treated. It should be suspected in any patient who presents with massive hemoptysis and had previous aortic thoracic surgery, but even it may be seen in patients without any history of operation on the thoracic aorta. Although, today in many centers endovascular therapy is done for these patients, but it is not the standard approach. Surgery in urgent situations has an essential role in saving the patients. Operative management consists of double lumen intubation and one lung ventilation, followed by femoral artery and vein cannulation. Then Posterolateral thoracotomy and achieving proximal and distal control on the aorta, applying cardiopulmonary bypass (CPB), separation the lesion, and bypass the segment of the diseased aorta by a synthetic graft.
