BACKGROUND AND OBJECTIVE: Post-intubation tracheal stenosis (PITS) and post-tracheostomy tracheal stenosis (PTTS) are serious complications in mechanically ventilated patients. Although the aetiologies and mechanisms of PITS and PTTS are quite different, little is known about the clinical impact of differentiating one from the other. METHODS: We retrospectively conducted a chart review of 117 patients with PITS and 88 patients with PTTS who were treated with interventional bronchoscopy at Samsung Medical Center between January 2004 and December 2013...

INTRODUCTION: Penetrating oesophageal injuries are extremely rare. Their timely recognition can be difficult and optimal treatment remains controversial. Early recognition of injury is possible with the help of a high index of suspicion and early radiological and endoscopic examinations. Prompt surgical intervention with primary repair of injury, should be the goal. PRESENTATION OF CASES: We describe two cases of penetrating oesophageal trauma where T-Tube placement through the oesophageal defect, was successfully employed...

It is difficult to directly observe glottal airflow velocity just above the glottis due to sensor size requirements and limited accessibility. We developed a miniature hot-wire probe and flexible fiberscopic high-speed imaging system for human examinations. Simultaneous direct measurement of glottal airflow velocity, subglottal pressure, and vocal fold vibration was achieved in a patient who was treated with a T-tube for tracheal stenosis. Airflow velocity changes at the anterior midline of the vocal folds were synchronized with subglottal pressure changes during each phonation cycle...

Several studies have shown the safety and feasibility of laparoscopic common bile duct exploration (LCBDE) as a minimally invasive treatment options for choledocholithiasis. Use of T-tube or biliary stent drainage tube placement after laparoscopic choledochotomy for common bile duct (CBD) stones is still under debate. This study tried to confirm the safety of spontaneously removable biliary stent in the distal CBD after LCBDE to allow choledochus primary closure. A total of 47 patients with choledocholithiasis underwent LCBDE with primary closure and internal drainage using a spontaneously removable biliary stent drainage tube (stent group, N = 22) or T-tube (T-tube group, N = 25)...

BACKGROUND: The rapid shallow breathing index (RSBI), which is the ratio between respiratory rate (RR) and tidal volume (VT), is one of the most widely used indices to predict weaning outcome. Whereas the diaphragm plays a fundamental role in generating VT, in the case of diaphragmatic dysfunction the inspiratory accessory muscles may contribute. If this occurs during a weaning trial, delayed weaning failure is likely since the accessory muscles are more fatigable than the diaphragm. Hence, we hypothesised that the traditional RSBI could be implemented by substituting VT with the ultrasonographic evaluation of diaphragmatic displacement (DD)...

Biliary leakage is a serious complication after liver resection and represents the major cause of post-operative morbidity. In spite of already identified risk factors, little is known about the role of intra-biliary pressure following liver surgery in the development of biliary leakage. Biliary decompression may have a positive impact and reduce the incidence of biliary leakage at the parenchymal resection site. 397 patients undergoing liver resection without bilioenteric anastomosis were included in the retrospective analysis of the risk factors for the development of biliary leakage focusing on the intra-operative reduction of the biliary pressure by T-tube and liver histology...

OBJECTIVES: Repair of laryngotracheal stenosis with pronounced side-to-side narrowing and involvement of the glottis is challenging and usually requires laryngotracheal reconstruction with rib cartilage interpositions. This technique, as first described by Couraud, needs prolonged postoperative stabilization with Montgomery T-tubes, imposing significant morbidity and discomfort on patients. We describe our initial experience with a modified laryngotracheal reconstruction technique that avoids the need for prolonged postoperative stenting...

In vitro growth of Pseudomonas aeruginosa biofilm on tympanostomy tubes showed that in Armstrong T-tubes, biofilm colonies were mainly located in the perpendicular junction between the body and the flanges, but in Paparella-type tube, they concentrated on the round rims. These 'weakness' zones can be the future target areas for geometry changes, and can be specifically coated with anti-biofilm materials.

Microfluidic devices are mircoscale fluidic circuits used to manipulate liquids at the nanoliter scale. The ability to control the mixing of fluids and the continuous nature of the process make it apt for solvent/antisolvent precipitation of drug-delivery nanoparticles. This review describes the use of numerous microfluidic designs for the formulation and production of lipid nanoparticles, liposomes and polymer nanoparticles to encapsulate and deliver small molecule or genetic payloads. The advantages of microfluidics are illustrated through examples from literature comparing conventional processes such as beaker and T-tube mixing to microfluidic approaches...

BACKGROUND: Most patients with postintubation tracheal stenosis are not ideal candidates for airway resection at presentation and their airways must be temporarily kept open by repeated bronchoscopic dilation (RBD). Meanwhile, some sufficiently recover by RBD without further airway resection requirement. We hypothesized whether systemic corticosteroids could lengthen RBD intervals, decrease the number of patients who eventually need airway resection, and shorten the required length of airway resection...

The hydatid disease caused by Echinococcus granulosus is an endemic parasitic disease affecting several Mediterranean countries. Echinococcal cysts are mostly located in the liver and the lung, but the disease can be detected anywhere in the body. In this study, we present uncommon extrahepatic localizations of primary hydatid disease. Patients who were operated on for hydatid disease or cystic lesions, which were later diagnosed as hydatid disease, between 2004 and 2010 were retrieved retrospectively. Patients with lesions localized outside the liver and the lung were enrolled in the study...

BACKGROUND: Leiomyosarcoma of vascular origin is a rare tumor, occurring mainly in the inferior vena cava (IVC). When involving the hepatic vein confluence, it often causes Budd-Chiari syndrome, and IVC removal with a complex hepatectomy is required (Mingoli in J Am Coll Surg 211:145-146, 2010; Griffin in J Surg Oncol 34:53-60, 1987; Heaney in Ann Surg 163:237-241, 1966; Fortner in Ann Surg 180:644-652, 1974). METHODS: A 57-year-old male, without previous oncological history, presented with Budd-Chiari syndrome due to a leiomyosarcoma extending to the supra-diaphragmatic IVC and involving the right and middle hepatic veins...
