Fecal microbiota transplantation and its potential therapeutic uses in gastrointestinal disorders.

Typical human gut flora has been well characterized in previous studies and has been noted to have significant differences when compared with the typical microbiome of various disease states involving the gastrointestinal tract. Such diseases include Clostridium difficile colitis, inflammatory bowel disease, functional bowel syndromes, and various states of liver disease. A growing number of studies have investigated the use of a fecal microbiota transplant as a potential therapy for these disease states.

Postpolypectomy Intramural Colonic Hematoma: The Conservative Management of a Potentially Fatal Complication.

Most medical professionals consider colonoscopy to be a safe procedure with a low rate of severe complications such as bowel perforation, gastrointestinal tract bleeding, or mortality. Bowel wall hematoma is a rare complication associated with colonoscopy that can result in significant morbidity and even mortality. We present a case of postpolypectomy hematoma diagnosed with CT imaging and successfully managed in a conservative fashion.

A randomized crossover comparison between the Laryngeal Mask Airway-Unique™ and the air-Q intubating laryngeal airway in children.

OBJECTIVES: The purpose of this randomized crossover study was to evaluate the feasibility of the air-Q intubating laryngeal airway (ILA) in clinical practice when compared with the Laryngeal Mask Airway-Unique(™) (LMA-U), the current standard of care for primary airway maintenance. AIM: We hypothesized that the ILA would have better airway seal pressures and laryngeal alignment than the LMA-U in anesthetized nonparalyzed children. BACKGROUND: The ILA is a newer supraglottic airway for children with design features that allow it to be used for primary airway maintenance and as a conduit for tracheal intubations. METHODS: Fifty healthy children, 6-36 months of age, 10-15 kg, who were scheduled for elective surgery in which the use of a size two LMA-U and size 1.5 ILA would be appropriate for airway maintenance, were enrolled into this randomized crossover study. Primary outcome measures were airway leak pressures and fiberoptic grades of view. Secondary outcome measures included ease and time for successful insertion, incidence of gastric insufflation, ventilation parameters, and complications. RESULTS: There were no statistically significant differences in regard to the ease of device insertion, time to ventilation, gastric insufflation, and ventilation parameters between the ILA and the LMA-U. All devices were successfully placed on the first attempt, and there were no instances of failure. There were statistically significant differences in the airway leak pressure between the ILA (19.0 ± 5.4 cmH(2)O) and the LMA-U (16.1 ± 4.9 cmH(2)O), P = 0.001. There were also statistically significant differences in the fiberoptic grades of view between the ILA and LMA-U, P = 0.004. CONCLUSIONS: The ILA had higher airway leak pressures and superior fiberoptic grades of view when compared with the LMA-U and can be a suitable alternative to the LMA-U in children weighing 10-15 kg.

Prospective evaluation of the self-pressurized air-Q intubating laryngeal airway in children.

OBJECTIVES: To assess the clinical efficacy of the self-pressurized air-Q ILA™ (ILA-SP). AIM: The purpose of this prospective audit was to evaluate the feasibility of the ILA-SP in clinical practice and generate data for future comparison trials. BACKGROUND: The ILA-SP is a new first-generation supraglottic airway for children with a self-adjusting cuff and lack of a pilot balloon. METHODS: Over a 4-month period, 352 children with an ASA physical status of I-III, newborn to 18 years of age, undergoing various procedures were studied. Data points assessed included insertion success rates, airway leak pressures, quality of ventilation, and perioperative complications associated with the use of this device. RESULTS: In 349 of the 352 patients in this study, the ILA-SP was used successfully as a primary supraglottic airway device in a variety of patients. Three patients required conversion to a standard laryngeal mask airway or a tracheal tube. The mean initial airway leak pressure for all patients was 17.8 ± 5.4 cm H(2)O, and 20.4 ± 5.5 cm H(2)O when re-checked at 10 min, which was statistically significant (P < 0.001). Complications were limited to 14 patients and related to reflex activation of the airway (coughing, laryngospasm, and bronchospasm) (n = 10), sore throat (n = 3), and blood staining on removal of the device (n = 1). There were no episodes of regurgitation, aspiration, or hoarseness. CONCLUSIONS: Acceptable clinical performance was demonstrated with the ILA-SP for a variety of procedures in infants and children with spontaneous and positive pressure ventilation. Future studies comparing this device to other supraglottic airways may provide useful information regarding the safety of the ILA-SP in pediatric clinical practice.
