Laparoscopic gastric pull-up for long gap esophageal atresia.
Esophageal replacement (ER) is indicated for long gap esophageal atresia (LGEA) when anastomosisis not possible, especially in cases without fistula or when elongation techniques have failed. The authors show their techniques and analyze preliminary results of the laparoscopic gastric pull-up (LGPU) for ERin LGEA. ⋯ Video-assisted esophageal replacement with the stomach for LGEA can be safely performed in children and infants, even after a previous mediastinal operation; however, larger comparative series are required in the future.

Comparative StudySurgical performance with head-mounted displays in laparoscopic surgery.
The difficulties of laparoscopic surgery include two-dimensional image projection and loss of alignment between the surgeon's hands and visual field. Head-mounted displays (HMDs) allow freedom from gazing at a stationary overhead monitor, thus improving ergonomics. Modern HMDs offer greatly improved image quality and reduced bulk and weight. We compared two types of HMDs with conventional overhead image display. ⋯ The high-resolution HMD offered significantly better image quality and allowed faster task performance than a lower resolution model of HMD, and both performed better than the overhead display. The high-resolution HMD was not significantly more comfortable than the low-resolution model, given its added weight. HMDs alone may only be of incremental benefit in improving performance in laparoscopic surgery.However, their greatest promise is in their combination with other advances in imaging and image manipulation technology, as they open the door to individualized image display.

Historical ArticleLaparoscopic revision of failed fundoplication and hiatal herniorraphy.
The aim of this study was to evaluate the mechanisms of failure after laparoscopic fundoplication and the results of revision laparoscopic fundoplication. ⋯ Laparoscopic redo antireflux surgery, performed in a laparoscopic fellowship program, produces excellent results that approach the success rates of primary operations.

Because of economic inflation, different-sized coins are in circulation in our country. The coin ingestion and retention in the esophagus are common problems in childhood. We evaluated the patients with coins retained in the esophagus and the impact of the size of the coins on lodgment. ⋯ Coin ingestion is rather common among childhood and its treatment may require an endoscopic approach. Most retained coins had a diameter between 23.45 and 26.00 mm. We think we could redesign our coins so that they would either be too big to ingest or so small they would always pass spontaneously.

Thoracoscopic aortopexy for treatment of tracheomalacia in infants and children.
Aortopexy is an established treatment method for severe tracheomalacia. It can be performed by thoracotomy or thoracoscopically. The purpose of this study is to review our experience with thoracoscopic aortopexy. ⋯ Thoracoscopic aortopexy is an effective treatment for severe tracheomalacia not controlled by conservative measures. It can be safely performed even in small infants as long as equipment and skill for pediatric thoracoscopy are available. The authors believe that thoracoscopic exposure offers advantages over open technique and is cosmetically more pleasing to patients and their families. It may result in less pulmonary complications, shorter hospital stay, and less narcotic requirement compared to open thoracotomy.
