Abstract Background Malignant tumors of the esophagus are the sixth leading cause of cancer-related deaths worldwide. Postoperative leakage of the esophago-gastrostomy leads to mediastinal sepsis, which is still associated with a high morbidity and mortality rate. The aim of this study was to describe the endoscopic view of the different severity grades of an anastomotic leakage. MethodsPatients Between June 2016 and September 2018, 144 patients were operated upon in the Department of Surgery, University of Munich, Germany. Among these patients, 34 (23.6%) presented with a leakage of the anastomosis. EndoscopyIn this retrospective analysis the focus is to describe different patterns of leakage of the anastomosis.Results We studied 34 patients in whom post-esophagectomy leakage of the anastomosis was detected and treated with an endoluminal vacuum sponge system. The leakage healed in 26 of 29 patients (success rate 89.7%). With increasing severity of leakage, the treatment time and the in-hospital mortality correspondingly increased. Furthermore, the incidence of development of a fistula to the tracheobronchial system increased with higher grades of leakage.ConclusionsExact descriptions of leakage are necessary to compare the cases and to prove post-treatment improvement. This is, to our knowledge, the first publication to present a leakage grading score in patients after esophagectomy including reconstruction with a gastric tube. This new grading system needs to be tested in further analyses, with special focus on prospective analysis.

AIM: Here we studied the role of meconium in the respiratory system on live and exited newborns (weight 250-3000 g). Throughout this study is followed the response of tracheal rings in acetylcholine and histamine in different molar concentrations (10-1, 10-2, 10-3, 10-4 mol/dm3).METHODS: To study the smooth tracheal musculature we used 23 tracheal preparations obtained from the newborns exited from meconium aspiration.RESULTS: Based on the functional analysis of the tracheal specimen we have concluded that the meconium aspiration did not change the smooth musculature response on acetylcholine and histamine when compared to control group, exited from lung inflammatory processes (e.g., pneumonia, bronchopneumonia, atelectasis, cerebral hemorrhage), where tracheal smooth musculature response is significant (P for other causes is not significant (P > 0.01).CONCLUSION: The conclusions suggest that meconium did not potentiate the constrictor action of acetylcholine and histamine in the tracheobronchial system and did not cause modulation of bronchomotor tonus in case of his aspiration. Meconium causes mild relaxation of smooth tracheal musculature with a mechanism which is not mediated by cyclooxygenase products, from tracheal epithelium or proteins. Also, direct activity in the smooth musculature of several tested acids seems to have no significant impact in increasing the tonus of respiratory airway of smooth tracheal musculature.

Pulmonary sequestration is an embryonic, cystic lung tissue that is supplied by systemic blood circulation. It is a nonfunctional lung parenchyma unconnected to normal tracheobronchial system. In cases of pulmonary sequestration, surgical interventions should be performed in order to prevent possible complications such as massive hemoptysis and infections. Preoperative imaging and treatment planning should be done carefully. We present an uncommon case of recurrent hemoptysis caused by intralobar pulmonary sequestration located in the left lower lobe.

AbstractAcute injuries of the tracheobronchial system are rare and life-threatening situations. Tracheal rupture most commonly occurs after blunt trauma to the chest. It is a rare but most concerning immediate complication of intubation. One-lung ventilation is required in lung surgery. Video assisted thoracoscopic procedures are an absolute indication for one-lung intubation. The double-lumen tube is the mainstay of one lung ventilation. Due to their larger size and rigidity, double lumen tubes are more difficult to insert, and complications are more common than with single lumen tubes. Opinions about the need for checking routinely the position of a double lumen tube by fiber optic bronchoscopy directly after intubation are divided. A 69-year-old woman with epidermoid lung carcinoma was scheduled for video assisted thoracoscopic left upper pulmonary lobectomy under general anaesthesia. The patient was prepared for the operation and itubated with the Carlens double lumen tube as usual. On introducing the camera into the thoracic cavity, the surgeon noted that the lungs were not completely collapsed. During blind adjustment the position of the tube the trachea was ruptured. The right-sided thoracotomy was performed and closed the greater part of the tracheal laceration. Only its upper 1.5-cm segment was surgically inaccessible because of the anatomical situation and thus remained unsutured. The patient received antibiotics, continuous airway humidification, analgesia with piritramide, and chest physiotherapy. She had no complications. In the literature, opinions about checking routinely the position of a double lumen tube by fiber optic bronchoscopy are divided.. Possibly, the very serious complication encountered in our patient could have been avoided, had the tube position been checked by bronchoscopy. The treatment strategy for post-intubation tracheal rupture depends on the size and location of the rupture, its clinical presentation, and the overall condition of the patient). Early surgical repair is the treatment of choice for most patients when a transmural tear with a length exceeding 2 cm. In our the combination of surgical and conservative treatment was performed. The uppermost part of the tear could not be sutured because of the anatomical situation, and so about 1.5 cm of the trachea remained open. The case is interesting from many perspectives. It shows that intubation with a Carlens tube is a potentially hazardous procedure, which should be performed only by experienced anaesthesiologists. Furthermore, our case report underscores the importance of checking routinely the position of a double lumen tube by fiber optic bronchoscopy. It provides evidence that minor tracheal lacerations can be successfully managed by conservative measures.
