Magnamosis for esophageal atresia is associated with anastomotic strictures requiring an increased number of dilatations.

Background/purpose: Magnamosis is a novel technique which utilizes high power magnets to anastomose the esophageal ends in children with esophageal atresia (EA) with or without a tracheoesophageal fistula (TEF), theoretically avoiding the need for thoracotomy. The objective of this study was to compare anastomotic stricture formation requiring dilatation after magnamosis versus after conventional anastomosis.

Methods: Our center treated the first 3 cases of EA ± TEF with magnamosis in Canada.

Use of Magnets as a Minimally Invasive Approach for Anastomosis in Esophageal Atresia: Long-Term Outcomes.

The majority of esophageal atresia (EA) patients undergo surgical repair soon after birth. However, factors due to patient characteristics, esophageal length, or surgical complications can limit the ability to obtain esophageal continuity. A number of techniques have been described to treat these patients with "long-gap" EA.

Repair of esophageal atresia with proximal fistula using endoscopic magnetic compression anastomosis (magnamosis) after staged lengthening.

We describe the treatment of a patient with long-gap esophageal atresia with an upper pouch fistula, mircogastria and minimal distal esophageal remnant. After 4.5 months of feeding via gastrostomy, a proximal fistula was identified by bronchoscopy and a thoracoscopic modified Foker procedure was performed reducing the gap from approximately 7-5 cm over 2 weeks of traction.

Magnetic gastrointestinal anastomosis in pediatric patients.

Background/purpose: To describe 17 patients who underwent magnetic, non-surgical gastrointestinal (GI) anastomoses.

Methods: Patients with GI obstruction, stenosis, or atresia were treated with image-guided and/or endoscopically placed discoid magnet pairs or catheter-based bullet-shaped magnet pairs.

Results: Anastomosis was achieved in 7 days in an 11-year-old with gastric outlet obstruction due to metastatic colon cancer.

Ectopic pancreas presenting with pancreatitis and a mesenteric mass.

Ectopic pancreas is defined by the presence of abnormally situated pancreatic tissue that lacks contact with normal pancreas and possesses its own duct system and vascular supply. Ectopic pancreas in the gastrointestinal tract is not uncommon. Moreover, there are several reported cases of adult ectopic pancreatitis in the literature, but to date, only two cases of pediatric ectopic pancreatitis have been reported.

Magnetic compression anastomosis as a nonsurgical treatment for esophageal atresia.

Background: We describe a unique technique to promote a nonsurgical esophageal anastomosis with magnets in children with esophageal atresia.

Objective: To evaluate the efficacy of magnetic lengthening of atretic esophageal ends to produce an anastomosis and to communicate our results after more than 2 years of follow-up.

Materials And Methods: Between September 2001 and March 2004, five children were selected for treatment.

Location of the ovaries in girls from newborn to 18 years of age: reconsidering ovarian shielding.

Background: Guidelines for ovarian shielding are to place a lead shield in the midline of the abdomen at the level of the umbilicus. However, the ovaries are routinely seen at other locations on all types of imaging examinations.

Objective: To determine the position of the ovaries in girls, newborn to 18 years of age, in order to assess efficacy of ovarian shield placement.

Retroperitoneal and deep-seated lipoblastoma: diagnosis by CT scan and fine-needle aspiration biopsy.

Lipoblastomas are most commonly superficially-located tumors. Our experience with three examples of deep-seated lipoblastomas is reported. The CT scans of all cases showed low-attenuation densities (less than 0 Hansfield units), strongly suggesting fatty composition.
