RESUMO
The abrupt onset of respiratory failure secondary to asthma, known as acute asphyxial asthma (AAA) in adults, is uncommonly reported in children. Here, we report a case of a child with the acute onset of respiratory failure consistent with AAA complicated by the finding of a neck mass during resuscitation. This 11-year-old boy with a history of asthma initially presented in respiratory failure with altered mental status after the complaint of difficulty in breathing minutes before collapsing at home. Initially, his respiratory failure was thought to be secondary to status asthmaticus, and treatment was initiated accordingly. However, a neck mass noted during the resuscitation was cause for concern, and other etiologies for his respiratory failure were considered, including an airway obstructing neck mass. After pediatric surgery and anesthesia consultation for intubation and possible tracheostomy placement, general anesthesia was induced in the operating room with an inhaled anesthetic, with prompt resolution of the bronchspasm and decompression of the neck mass. Review of the imaging and clinical course ultimately yielded a diagnosis of cervical lung herniation as the etiology of his neck mass. We report this case of AAA and cervical lung herniation and a review of the literature of these 2 uncommon phenomena in children.

BACKGROUND: Single-incision laparoscopic surgery (SILS) is increasingly being used to treat acute appendicitis. Existing SILS techniques suffer from inefficient triangulation and poor ergonomics. In an effort to improve on existing SILS techniques, we developed the magnet-assisted single trocar (MAST) appendectomy. SUBJECTS AND METHODS: We retrospectively analyzed all MAST appendectomies performed between March 2010 and February 2011. Outcomes included demographics, diagnosis, operative time, hospital stay, and complications. RESULTS: Twenty-three MAST appendectomies were performed in 10 boys and 13 girls. The mean age at operation was 12.22 years (range, 5-19 years), and the mean weight was 46.5 kg (range, 25-82 kg). At presentation the mean white blood cell count was 15,000 with 74% polymorphonuclear neutrophils. The mean operative time was 61 minutes (range, 20-105 minutes), and length of stay was 3.6 days (range, 1-7 days). In total, 4 operations (17%) required one additional 5-mm trocar to complete the operation, and none was converted to an open operation. There were no intraoperative complications, nor were there any wound infections. CONCLUSIONS: MAST appendectomy is safe and effective in children. Magnetic instruments provide excellent triangulation and improve ergonomics. This technique uses a single 12-mm trocar and can be performed without the aid of a surgical assistant.

Single-site umbilical incision laparoscopic surgery (SSULS) is increasingly being used to treat a variety of childhood surgical diseases. Existing SSULS approaches have inefficient triangulation and poor ergonomics. In an effort to overcome these shortcomings, magnet-assisted laparoscopy was developed. Specialized magnetic graspers are introduced through a standard 12-mm port and are controlled by a powerful external magnet. This study is a retrospective analysis of all magnet-assisted laparoscopic operations performed at the Fundacion Hospitalaria Private Children's Hospital from September 2009 to January 2011. Outcomes include demographics, diagnosis, operative time, intraoperative complications, and conversion rates. Forty-four magnet-assisted laparoscopic operations were performed. The operations included 23 appendectomies, 8 cholecystectomies, 3 Nissen fundoplications, 2 gastrojejunostomies, 2 splenectomies, 2 ovarian tumor/cyst resections, 1 retroperitoneal lymphangioma resection, 1 left adrenalectomy, 1 total abdominal colectomy and 1 pulmonary wedge resection. The mean operative times for the most commonly performed operations were 61 minutes for appendectomy and 93 minutes for cholecystectomy. The operations were classified as follows: Group I, adjunct to conventional laparoscopy (5 operations); Group II, adjunct to multiple-access umbilical laparoscopy (11 operations); and Group III, true single-port laparoscopy (28 operations). Among Group II/III operations, 6 operations required 1 additional port outside the umbilicus. No operations required more that 1 additional port, and no operations were converted to the open technique. There were no intraoperative complications. Magnet-assisted laparoscopic surgery is safe and effective in children. The use of magnetic graspers improves triangulation and ergonomics while reducing the number and size of abdominal incisions.
