Aim: Ingestion of multiple magnets is increasing these last 15 years in children. They have resulted in numerous reports of serious gastrointestinal complications such as bowel obstruction, ischaemia, necrosis, perforation and fistula formation and even led to death. The increasing number of world-wide reports of complications secondary to magnet ingestion and a frequently delayed diagnosis point to a lack of awareness about these risks among medical care-givers in our country and parents in general.Methods: We reviewed retrospectively all cases of multiple magnet ingestion that required a gastro-intestinal or surgical procedure for removal from 2009 to 2020.Results: Five children underwent gastroscopy removal and three colonoscopy removal of the magnets. Five patients required surgical (laparotomy or laparoscopy) removal of multiple magnets with intestinal perforations.Conclusions: We propose an updated management algorithm for multiple magnet ingestion to highlight awareness among primary physicians and parents of the presenting circumstances and symptoms as well as the potential complications associated with multiple magnet ingestion.

Acute appendicitis is the most common cause of acute abdominal pathology in children. However, other rare non-inflammatory non-neoplastic disorders involving the appendix may manifest as surgical emergencies. This study aimed to describe these atypical entities and present representative cases. The database of a tertiary children's medical center was reviewed for all the patients aged 0-18 years who underwent urgent appendectomy between June 2014 and December 2019, for rare disorders of the appendix unrelated to inflammatory or neoplastic processes. Of 1367 patients who underwent appendectomy, 1345 were operated urgently or emergently. Of these, six, all males, mean age 32.6 months (range 0.7-76), underwent appendectomy for rare surgical complications that involved the appendix. These included torsion of the appendix (2), a strangulated internal hernia through an appendicular ring (1) or through a mesoappendix gap (1), an incarcerated appendix in an acute hernia sac (1), and appendiceal intussusception (1). In all cases, the role of the appendix in the pathologic process was unexpected and came as a surprise to the surgeon. During a median follow-up of 4.2 months (range 1-8 months), one patient underwent relaparotomy for small bowel obstruction 4 weeks after the original procedure.Conclusion: The appendix in children can be the source of rare pathological disorders that present as surgical emergencies. Familiarity with these entities may aid in achieving accurate preoperative diagnosis and contribute to surgical team orientation on exploratory laparotomy. However, correct diagnosis is often only established during timely surgical intervention. [ABSTRACT FROM AUTHOR]

Purpose: Over the last 15 years thoracoscopic lobectomy for congenital and acquired lesions has become an accepted modality in pediatric thoracic surgery. There is still debate about the need to perform a complete lobectomy for some of these lesions, and some advocate observation rather then resection, despite possible longterm complications of untreated lesions. High-resolution computed tomography (CT) scans and physical findings at the time of surgery, along with new advanced techniques, now allow for discrete partial anatomic resections, which may preserve normal lung. This study evaluates the feasibility and early results using these techniques in selected cases. Patients and Methods: With institutional review board approval, the records of all patients undergoing thoracoscopic lung resection were reviewed. From January 2006 to December 2012, 23 patients, ranging from 1 month to 16 years of age and weighing 3.8-42 kg, underwent thoracoscopy for planned resection. Pathology was congenital cystic lung disease in 19 patients, bronchiectasis in 3 patients, and arteriovenous malformation in 1 patient. In each case findings on CT scan and at the time of surgery warranted consideration of lung-preserving surgery. Procedures were performed through three ports using single lung ventilation and CO2 insufflation to achieve lung collapse. The LigaSure device (Covidien, Norwalk, CT) was the primary instrument used to seal and divide the lung parenchyma and seal vessels. Results: All procedures were completed successfully thoracoscopically. An anatomic segmental resection was achieved in 22 of 23 cases. Operative time ranged from 30 to 300 minutes (mean, 120 minutes). Segmental resections included the left upper lobe apical/posterior (n = 4), lingula (n = 3), left lower lobe superior (n = 5), medial or posterior basal (n = 3), right middle lobe medial (n = 1), right upper lobe apical (n = 1), right lower lobe superior (n = 4), and posterior basal (n = 2). Two patients had more than one segment excised. Chest tubes were left in for 24 hours in 16 cases, 48 hours in 4 cases, and 5 days in 1 case. Hospital stay ranged from 1 to 6 days (mean, 2 days). Follow-up CT scans obtained at 1-6 years (mean, 28 months) show no residual disease in 20 of 21 patients. One patient underwent a nonanatomic resection and had evidence of recurrent congenital pulmonary airway malformation at the 4-year follow-up. This patient underwent a secondary thoracoscopic resection. Conclusions: Thoracoscopic lung-conserving therapy is technically feasible and safe in infants and children. The magnification provided by a thoracoscopic approach makes identification of segmental anatomic planes easier, aiding in safe dissection and resection. Anatomic resection appears to be associated with a low morbidity. It may be appropriate in the case of bilateral or extensive disease or in cases where the diseased tissue is clearly limited to an anatomic segment. Continued long-term follow-up is needed.

Abstract: Background: The “Nuss” procedure for repair of pectus excavatum is performed with increasing frequency worldwide. We describe a technique of performing relaxing or “kerf” incisions along the cartilaginous ribs at the point of maximal chest wall concavity to facilitate retrosternal dissection and to reduce chest wall tension. The effects on operative parameters and long-term changes in cardiopulmonary function and appearance were evaluated prospectively. Methods: Thirty patients underwent a Nuss procedure for the period from 2001 to 2004. Fifteen patients underwent a modified Nuss (MN) with sternocostal “relaxing” incisions, and these were compared to 15 patients undergoing a standard Nuss (SN). Data were prospectively gathered and included the number of relaxing incisions, bar number, blood loss, duration of epidural analgesia, number of days to discharge, and preoperative and postoperative cardiopulmonary function measures. Results: The average Haller index of the SN group was 3.9 ± 0.7 vs MN group index of 4.6 ± 1.6 (P < .05). The median number of relaxing incisions in the study group was 4.0 ± 0.7 (range 3 - 8). There were no significant differences between the study groups in any of the operative parameters analyzed, including blood loss, days of epidural requirements or days to reach functional independence. Nor were there differences in the improvement in subjective appearance, complications, pulmonary function, cardiac output at rest, oxygen transport or minute ventilation at maximal exercise. Subjectively, bar positioning and the intraoperative visualization was easier with the relaxing incisions. Conclusions: The addition of sternocostal relaxing incisions to the standard Nuss procedure appears to facilitate retrosternal dissection and bar placement, but no changes in long-term function or cosmesis were noted. The use of relaxing incisions appears to be safe and may facilitate operative visualization of retrosternal structures. [Copyright &y& Elsevier]

Abstract: Background: The optimal treatment of pectus carinatum (PC) deformities is unclear. We propose a nonoperative approach using a lightweight, patient-controlled dynamic chest-bracing device. Material and Methods: With ethical approval, 24 patients with PC were treated at the Alberta Children''s Hospital between January 1998 and April 2005. There were 6 (25%) females and 18 (75%) males, with a mean age of 12.9 years at the onset of treatment. Treatment involved fitting of a lightweight, patient-controlled chest brace, worn for 23 hours per day (correction phase [CP]) until the convex deformity was corrected. Following correction of the deformity, bracing was reduced to 8 hours per day (maintenance phase) until axial skeletal maturation ceased. Monitoring was done by measurement of the external pectus carinatum protrusion as well as subjective patient and surgeon appraisal of appearance and exercise tolerance. Results: Nineteen (79.2%) patients have completed initial treatment (mean CP time, 4.3 ± 2.1 months). There were 3 patients (12.5%) who were noncompliant, and 2 (8.3%) are still in the initial CP phase of therapy. Fourteen (58.3%) patients are presently in maintenance phase, nocturnally braced, and 2 (8.3%) have completed therapy. In patients completing initial treatment, the protrusion pectus carinatum protrusion (pre 22 ± 6 vs post 6.0 ± 6.2) and subjective appearance (change + 1.8±0.4) showed a significant improvement (P < .001 for both) with no change in exercise tolerance. Conclusion: Compressive bracing results in a significant subjective and objective improvement in PC appearance in skeletally immature patients. However, patient compliance and diligent follow up appear to be paramount for the success of this method of treatment. Further studies are required to show the durability of this method of treatment.
