Undescended testes (UDT), where one or both testes fail to migrate to the base of the scrotum, can be congenital (2-5% of newborn males) or acquired (1-2% of males). The testis may be found in any position along its usual line of descent. Cryptorchidism affects the developing testicular germ cells and increases the risk of infertility and malignancy. Clinical management aims to preserve spermatogenesis and prevent the increased risk of seminoma. Examination to document the testicular position will guide the need for imaging, medical management and the surgical approach to orchidopexy...

The surgical repair of inguinal hernia and hydrocele is one of the most common operations performed in pediatric surgery practice. This article reviews current concepts in the management of inguinal hernia and hydrocele based on the recent literature and the authors׳ experience. We describe the principles of clinical assessment and anesthetic management of children undergoing repair of inguinal hernia, underlining the differences between an inguinal approach and minimally invasive surgery (MIS). Other points discussed include the current management of particular aspects of these pathologies such as bilateral hernias; contralateral patency of the peritoneal processus vaginalis; hernias in premature infants; direct, femoral, and other rare hernias; and the management of incarcerated or recurrent hernias...

Biliary disease in children has changed over the past few decades, with a marked rise in incidence-perhaps most related to the parallel rise in pediatric obesity-as well as a rise in cholecystectomy rates. In addition to stone disease (cholelithiasis), acalculous causes of gallbladder pain such as biliary dyskinesia, also appear to be on the rise and present diagnostic and treatment conundrums to surgeons.

Hypertrophic pyloric stenosis is a common surgical cause of vomiting in infants. Following appropriate fluid resuscitation, the mainstay of treatment is pyloromyotomy. This article reviews the aetiology and pathophysiology of hypertrophic pyloric stenosis, its clinical presentation, the role of imaging, the preoperative and postoperative management, current surgical approaches and non-surgical treatment options. Contemporary postoperative feeding regimens, outcomes and complications are also discussed.

Douglas C Barnhart
Despite the frequency with which antireflux procedures are performed, decisions about gastroesophageal reflux disease treatment remain challenging. Several factors contribute to the difficulties in managing gastroesophageal reflux. First, the distinction between physiologic and pathologic gastroesophageal reflux (gastroesophageal reflux disease-GERD) is not always clear. Second, measures of the extent of gastroesophageal reflux often poorly correlate to symptoms or other complications attributed to reflux in infants and children...

Shawn D St Peter, Charles L Snyder
Appendectomy has been the standard of care for appendicitis since the late 1800s, and remains one of the most common operations performed in children. The advent of data-driven medicine has led to questions about every aspect of the operation-whether appendectomy is even necessary, when it should be performed (timing), how the procedure is done (laparoscopic variants versus open and irrigation versus no irrigation), length of hospital stay, and antibiotic duration. The goal of this analysis is to review the current status of, and available data regarding, the surgical management of appendicitis in children...

Appendectomy is currently considered the standard of care for children with acute appendicitis. Although commonly performed and considered a safe procedure, appendectomy is not without complications. Non-operative management has a role in the treatment of both uncomplicated and complicated appendicitis. In uncomplicated appendicitis, initial non-operative management appears to be safe, with an approximate 1-year success rate of 75%. Compared to surgery, non-operative management is associated with less disability and lower costs, with no increase in the rate of complicated appendicitis...

Appendicitis represents the most common abdominal surgical emergency in the pediatric age group. Despite being a relatively common condition, the diagnosis of appendicitis in children can prove to be challenging in many cases. The goal of this article is to review the predictive utility for presenting signs and symptoms, laboratory tests, and imaging studies in the diagnostic work-up of appendicitis. Furthermore, we sought to explore the predictive utility of composite measures based on multiple sources of diagnostic information, as well as the utility of clinical pathways as a means to streamline the diagnostic process...

Paolo Campisi, Vito Forte
Tracheotomy refers to a surgical incision made into a trachea. Tracheostomy, on the other hand, refers to a surgical procedure whereby the tracheal lumen is positioned in close proximity to the skin surface. Tracheostomy is an uncommon procedure in the pediatric population. When required tracheostomy is typically performed as an open surgical procedure under general anesthesia with the patient intubated. However, it may need to be performed under local anesthesia or over a rigid bronchoscope in the patient with a precarious airway...

Regenerative medicine offers hope of a sustainable solution for severe airway disease by the creation of functional, immunocompatible organ replacements. When considering fetuses and newborns, there is a specific spectrum of airway pathologies that could benefit from cell therapy and tissue engineering applications. While hypoplastic lungs associated with congenital diaphragmatic hernia (CDH) could benefit from cellular based treatments aimed at ameliorating lung function, patients with upper airway obstruction could take advantage from a de novo tissue engineering approach...

Juan L Antón-Pacheco
Tracheobronchial obstruction is infrequent in children and still remains a challenging matter of concern. Management alternatives vary from conservative treatment to complex surgical techniques or endoscopic interventional procedures. Airway stenting in children is relatively recent and follows the trail of the experience in adult patients. Nevertheless, there are basic differences between both age groups like the benign nature of most obstructions and the small size of the pediatric airway. These specific features raise the issues of the precise role of tracheobronchial stenting in children and the selection of the most adequate device...

Bethany J Slater, Steven S Rothenberg
Tracheoesophageal fistula (TEF) is a relatively rare congenital anomaly. Surgical intervention is required to establish esophageal continuity and prevent aspiration and overdistension of the stomach. Since the first successful report of thoracoscopic TEF repair in 2000, the minimally invasive approach has become increasingly utilized. The main advantages of the thoracoscopic technique include avoidance of a thoracotomy, improved cosmesis, and superior visualization of the anatomy and fistula afforded by the laparoscope׳s magnification...

The term vascular ring refers to congenital vascular anomalies of the aortic arch system that compress the esophagus and trachea, causing symptoms related to those two structures. The most common vascular rings are double aortic arch and right aortic arch with left ligamentum. Pulmonary artery sling is rare and these patients need to be carefully evaluated for frequently associated tracheal stenosis. Another cause of tracheal compression occurring only in infants is the innominate artery compression syndrome...

Jose Carlos Fraga, Russell W Jennings, Peter C W Kim
Tracheomalacia (TM) is defined as an increased collapsibility of the trachea due to structural anomalies of the tracheal cartilage and/or posterior membrane. Tracheomalacia has a wide range of etiologies but is most commonly present in children born with esophageal atresia and tracheal esophageal fistula. Clinical symptoms can range from minor expiratory stridor with typical barking cough to severe respiratory distress episodes to acute life-threatening events (ALTE). Although the majority of children have mild-to-moderate symptoms and will not need surgical intervention, some will need life-changing surgical treatment...

Patricio Varela, Luca Pio, Michele Torre
Primary tracheobronchial tumors are rare lesions that can be benign or malignant, with different location along the airway tree. Symptoms may include wheezing, chronic pneumonia, asthma, chest pain, recurrent cough, atelectasis, haemoptysis, and weight loss. Due to the heterogeneity of symptoms, diagnosis can be difficult and the airway involvement can lead progressively to a bronchial or tracheal obstruction. Due to the rarity of primary tracheobronchial tumors in children, there are not any oncological guidelines on pre-operative work-up, treatment, and follow-up...

Richard J Hewitt, Colin R Butler, Elizabeth F Maughan, Martin J Elliott
Congenital tracheobronchial stenosis is a rare disease characterized by complete tracheal rings that can affect variable lengths of the tracheobronchial tree. It causes high levels of morbidity and mortality both due to the stenosis itself and to the high incidence of other associated congenital malformations. Successful management of this complex condition requires a highly individualized approach delivered by an experienced multidisciplinary team, which is best delivered within centralized units with the necessary diverse expertise...

Niall D Jefferson, Aliza P Cohen, Michael J Rutter
Subglottic stenosis (SGS) is a congenital or acquired condition characterized by a narrowing of the upper airway extending from just below the vocal folds to the lower border of the cricoid cartilage. With the introduction of prolonged intubation in neonates (mid 1960s), acquired SGS became the most frequent cause of laryngeal stenosis; unlike congenital SGS, it does not improve with time. Laryngeal reconstruction surgery evolved as a consequence of the need to manage these otherwise healthy but tracheotomized children...

Kate A Stephenson, Michelle E Wyatt
Glottic stenosis is a fixed, focal narrowing at the level of the laryngeal inlet, the true vocal cords. It may be either congenital or acquired and be related to a wide range of etiologies. The stenosis may be either anterior, posterior, or in rare cases, complete. Isolated glottic stenosis is rare; lesions often involve adjacent regions, namely the subglottis. A diagnosis is made from careful history and examination, including evaluation by microlaryngoscopy and bronchoscopy. The management of glottic stenosis is challenging and should be tailored to each individual case...
