Valeria Silva Merea, Paul C Bryson
OBJECTIVES: The utility of topical mitomycin C (MMC) as an adjuvant treatment in the management of laryngeal and tracheal stenosis has been studied; however, the ideal timing of MMC application has not been fully elucidated. There is a paucity of studies evaluating the timing of MMC application after surgical airway intervention for stenosis. The purpose of this study is to describe a novel technique for MMC application that allows for delayed application in the unsedated, office-based setting, approximately one week following endoscopic airway dilation...

BACKGROUND: Early recurrence of atrial fibrillation (AF) is common following a successful electrical cardioversion (ECV). The purpose of this study was to investigate the hypothesis that AF recurrence is related to atrial electrical inhomogeneity, which may influence the P wave characteristics. METHODS: Two hundred ninety-one consecutive persistent AF patients who underwent ECV were enrolled, and evaluated for AF recurrences one month after the ECV. Patients with open-heart surgery, a history of catheter ablation, and an unsuccessful ECV were excluded...

Juvenile nasopharyngeal angiofibroma (JNA) is a hypervascular tumor and uncontrolled hemorrhage makes its removal very difficult. Although preoperative intravascular embolization of a feeding artery is recommended, serious complications such as iatrogenic thrombosis in the brain and insufficient decrease in blood flow to the tumor are concerns. Recently, coblation plasma technology has been reported to be useful for tumor removal with minimum hemorrhage under a clear surgical field. Here we report successful removal of advanced JNA without preoperative embolization, using intraoperative ligation of the maxillary artery and coblation plasma technology...

A 3-day-old Swiss Warmblood colt was diagnosed with uroabdomen after urinary bladder rupture. The foal had classical electrolyte abnormalities (hyponatremia, hypochloremia and hyperkalemia) on presentation. The foal was supported prior to surgery with intravenous fluids and the electrolyte abnormalities were treated with physiologic saline, glucose and insulin. Urine could not be drained from the abdomen prior to surgery because the omentum was continuously occluding the drainage cannula and due to progressive abdominal distension, it was decided to pursue surgery without further correction of electrolyte abnormalities...

Introduction: With the development of laparoscopic skills, the laparoscopic common bile duct exploration (LCBDE) and laparoscopic cholecystectomy (LC) has become the standard surgical procedure for choledocholithiasis. We usually use Hem-o-lok clips to control cystic duct and vessels, which is safe on most occasions and has few perioperative complications such as major bleeding, wound infection, bile leakage, and biliary and bowel injury. However, a rare complication of post-cholecystectomy clip migration (PCCM) increases year by year due to the advancement and development of LC, CBD exploration as well as the wide use of surgical ligation clips...

OBJECTIVE: Endoscopic endonasal surgery has evolved in recent decades, requiring comparable advances in reconstructive techniques. This study aimed to retrospectively review outcomes of endoscopic anterior skull base reconstruction and to analyze factors associated with failures. METHODS: Data from patients who underwent endoscopic endonasal anterior skull base reconstruction in a single institution between 1998 and 2017 were collected. Patients were stratified according to selected risk factors: sex; age; previous surgery; disease treated (cerebrospinal fluid leaks, benign tumors, malignant tumors); single or multiple defects; defect dimension (<1 cm2 , 1-2 cm2 , 2-6 cm2 , >6 cm2 ) and site (olfactory cleft, ethmoidal roof, planum sphenoidalis, posterior wall of frontal sinus); reconstruction technique (overlay graft, multilayer grafts, pedicled flap) and materials used; postoperative radiotherapy; and year of surgery...

BACKGROUND: The treatment of pediatric sinusitis continues to be a controversial topic. It has been recommended to treat pediatric chronic rhinosinusitis (CRS) with adenoidectomy before proceeding to more invasive techniques. There are concerns regarding side effects of endoscopic sinus surgery in pediatric patients. With the advent of balloon catheter dilation (BCD) as a minimally invasive technique, some authors are recommending up front adenoidectomy with BCD in order to maximize disease resolution while minimizing risk...

Many studies have focused on the identification of risk factors and prevention of anastomotic leakage following rectal cancer surgery. However, there is little knowledge regarding classification and management of anastomotic leakage in clinic. Herein, we reviewed and summarized the classification and management of anastomotic leakage after rectal cancer surgery. The relevant treatments of anastomotic leakage should be chosen based on patient's manifestation, including general and local reactions, anatomical location, and nature of the leakage (contained or free, controlled or uncontrolled leakage)...

During a sinus lift procedure the main requirement in order to position an implant is to have a maxillary sinus floor cortical bone thick enough to guarantee a primary stability in the implant inserted. In this way, the healing process is facilitated and osseointegration of the titanium surface may occur simultaneously, thus reducing the waiting time for the engraftment of the implant into the body. Unfortunately, these conditions are not always present. Hence, the need of developing an alternative approach that could simultaneously allow to perform sinus floor elevation along with an implant placement...

The clinical distinction of chronic respiratory rhinitis appears to confirm the evo-devo theory of the three noses. The authors report two cases of advanced allergic rhinitis, in which chronic inflammation had induced a violaceous colour of the mucosa of the respiratory nose and a whitish polypoid appearance of the free edge of the middle turbinate. Nose and paranasal sinus CT scan revealed, beyond the virtual nasal cavities observed on nasal endoscopy and CT imaging, normal radiolucency or only minor opacities of the ethmoid (i...

OBJECTIVE Sphenoid wing meningiomas are a heterogeneous group of tumors with variable surgical risks and prognosis. Those that have grown to a very large size, encasing the major cerebral arteries, are associated with a high risk of stroke. In reviewing the authors' series of giant sphenoid wing meningiomas, the goal was to evaluate how the extent of the tumor's invasion of surrounding structures affected the ability to safely remove the tumor and restore function. METHODS The authors conducted a retrospective study of a series of giant sphenoid wing meningiomas operated on between 1996 and 2016...
