Femoral artery thrombosis in an 11-year old boy due to a blunt trauma.

An 11-year old boy presented with a blunt trauma in the right inguinal area after a bicycle accident. Initial clinical picture was indicative of decreased arterial blood supply to the right lower extremity and the diagnostic confirmation was made with a colour flow Doppler ultrasonography. During operative investigation, a thrombosis of the common femoral artery, 3.5 cm in length, was found. The thrombotic part of the femoral artery was removed and replaced with a venous graft taken from the major saphenous vein, before the saphenofemoral junction. Postoperative course was uneventful. Traumatic thrombosis of the common femoral artery as a result of a blunt trauma is very rare, as only 4 relevant cases have been described previously.

Hydrocele in Pediatric Population.

Hydrocele is a collection of fluid within the tunica vaginalis. Based upon the etiology and the pathophysiology, it is divided into, the primary and secondary. The primary hydrocele includes the neonatal or the congenital, the communicating and the non-communicating or the closed or the adult type. The secondary hydrocele can develop in the substrate of a pre-existing disease. After systematic and thorough systematic and thorough research of the relevant literature, we aim at describing all the aspects of this entity, with specific emphasis on the issues that remain unanswered from the scientific community.

Clinical image. Chylolymphatic mesenteric cyst in a 3-month old infant.

Chylolymphatic mesenteric cysts are extremely rare among children. Herein we report a case of a 3-month old infant that was admitted to the Emergency Department due to repeated vomiting. Preoperative ultrasonography demonstrated the presence of a thin-walled multiloculated cystic lesion in the right abdomen. Patient underwent then elective surgical excision. Histopathological examination documented the diagnosis of cystic lymphangioma type III, according to Lozanoff classification.

Intramuscular hemangioma in the anterior scalene muscle in an infant boy: a case report.

The extremely rare localization of an intramuscular hemangioma (IMH) into the anterior scalene muscle was the motive for the present case report, aiming to highlight major, atypical characteristics. An 11-month-old boy with free medical history presented with a painless and progressively growing lesion 4.5 × 4 cm in diameter, located in the left supraclavicular region over the last 4 months. During physical examination, the presence of a painless, non-pulsating, non-adhesive to the overlying skin lesion was documented. Color Doppler flow ultrasonographic examination demonstrated the increased blood supply to the aforementioned lesion. Thus, we planned an elective surgical excision of the lesion in healthy limits. The postoperative course was uneventful, and the patient was discharged on the second postoperative day in good general condition. Histopathologic examination revealed the presence of hemangioma surrounded by connective tissue bundles and striated muscle fibers. IMHs do not follow the general rule of regression, beyond the age of 6-12 months, with no trend to increase over time. Accurate preoperative diagnosis is challenging. Color Doppler flow ultrasonographic examination is the imaging modality of choice during the preoperative assessment. Surgical excision of the IMH in healthy limits is the most appropriate treatment option.

Fusiform Cervical Mass in a 6-Year Old Boy; Do not Forget the Thymic Cyst.

Cervical thymic cyst is a rare clinical entity, with approximately one hundred cases reported in the literature so far. The purpose of this case report is to highlight some certain features, along with an extensive research of the relevant literature. A 6-year-old boy was admitted to the Otorhinolaryngology Department due to the presence of a left-sided, painless, latero-cervical swelling, first observed by his parents 2 weeks ago. Physical examination revealed a painless, well-delineated mass, with no signs of inflammation. No enlarged cervical nodes were present. The mass extended from the mandibular angle, under the sternocleidomastoid muscle, in proximity with the ipsilateral neurovascular bundle. Ultrasound transverse gray-scale panoramic view detected a wellcircumscribed lesion, with fine echogenic foci, appearing in close proximity with the upper pole of the left thyroid lobe and the ipsilateral common carotid artery. Elective surgical intervention with complete mass excision was performed. Histopathological examination confirmed the diagnosis of a cervical thymic cyst. Cervical thymic remnants represent a group of neck masses that pediatricians and pediatric surgeons should consider in differential diagnosis of both cystic and solid neck masses. Most cystic cervical thymic masses are found in the lower third of the anterior neck, extending deep to the sternocleidomastoid muscle, featuring close anatomic relationship with the composites of the ipsilateral carotid sheath. Elective surgery is kept as the treatment of choice, after ruling out the possibility of subject immunologic disturbance.

Early diagnosis and surgical intervention untie the Gordian knot in newborns with colonic atresia: report of two cases and review of the literature.

Incidence of colonic atresia in living infants ranges from 1:5,000 to 1:60,000 (average 1:20,000). It constitutes 1.8 to 15% of all cases of atresia of the gastrointestinal tract. In 58.56-75% of all cases is right-sided. We aim, through the presentation of two cases of colonic atresia which we encountered and after systematic research of the current literature, at addressing three major issues: diagnostic approach, operative strategy and management of the prognostic parameters of the colonic atresia. The common parameter in these two cases was the early diagnosis, which played a significant role in the uncomplicated postoperative course. The first case was a type I sigmoid atresia. Contrast's escape during contrast enema examination due to accidental rupture of the distal part of the colon led to diagnosis. Side-to-side anastomosis, restoration of the rupture and a central loop sigmoidostomy were urgently performed. The second case was a type III atresia at the level of the ascending colon, which was early diagnosed via pregenital ultrasonography, in which colonic dilation was depicted. Restoration of the intestinal continuity early after birth was performed at a time. In conclusion, we believe that early diagnosis, selection of the appropriate operative strategy and prompt recognition of potential post-operative complications, especially rupture of the anastomosis, contribute to the optimization of the prognosis in patients with colonic atresia.

Covered perforation of Meckel's diverticulum ulcer to transverse colon: highlighting the urgent intervention and the avoidance of a dramatic evolution (case report and literature review).

Meckel's diverticulum represents a remnant of the proximal end of the omphalomesenteric duct, which constitutes a connection between the middle intestine and the vitelline vesicle. It is the most common congenital anomaly of the gastrointestinal tract and is found in approximately 0.3-2% of the general population. Complications such as hemorrhage, bowel obstruction, inflammation, perforation, intussusception, volvulus and malignant transformation develop in only 4-4.8% of all patients, with most cases presenting in childhood, while relative risk decreases during life. The aim of the present study is to present our experience in managing a 15-year old male patient with Meckel's diverticulum covered perforation. It was a case of disguised perforation of the Meckel's diverticulum, with development of adhesions to the anterior surface of the right third of the transverse colon, which was successfully treated on the basis of emergency. Diagnosis was made intraoperatively and was documented by histological examination of the excised diverticulum.

Fountain's Sign as a Diagnostic Key in Acute Idiopathic Scrotal Edema: Case Report and Review of the Literature.

The acute idiopathic scrotal edema (AISE) is a self-limited disease of unknown etiology, characterized by edema and erythema of the scrotum and the dartos, without expansion to the underlying layers of scrotum's wall or to the endoscrotal structures. Boys younger than 10 years old are usually involved in 60-90% of all cases. Diagnosis is made after exclusion of other causes of acute scrotum. We present a case of a 7-year old boy, who was admitted to the Emergency Department due to development of scrotal edema and erythema over the last 48 hours, which extended to the base of the penis. The patient mentioned that he first noticed the erythema on the anterior surface of the right hemiscrotum, which gradually extended. Physical examination did not reveal presence of pathology involving the endoscrotal structures, indicative of need for urgent surgical intervention. Transillumination was negative for blue dot sign. Ultrasonographic examination of the scrotum documented the homogeneity of the testicular parenchyma, while color Doppler revealed the presence of fountain's sign (equal arterial blood supply to both testicles). Conservative strategy was followed and the patient gradually improved within the next three days. In conclusion, meticulous physical examination along with ultrasonographic examination of the suffering scrotum, especially with the highlighting of fountain's sign with color Doppler, document the diagnosis of AISE. Thus, need for urgent surgical investigation of the suffering scrotum due to diagnostic doubt is limited.

Cystic Lymphangioma of the Chest Wall in a 5-Year-Old Male Patient: A Rare and Atypical Localization-A Case Report and Comprehensive Review of the Literature.

Lymphangioma is a benign congenital malformation. The extremely rare and atypical localization of a lymphangioma in the chest wall was the real motive for the present case study. A 5-year-old boy was admitted to the Emergency Department of the 1st Department of Pediatric Surgery, Aristotle University of Thessaloniki, due to the presence of a mildly painful swelling in the left lateral chest wall, which was first noticed three months ago, after a blunt injury during sport. Physical examination revealed the presence of a palpable, spherical, painful, nut-sized subcutaneous lesion in the left lateral chest wall, respectively, with the anterior axillary line, at the height of the 6th to 7th intercostal space. Presence of ecchymosis on the overlying skin was also noticed. During palpation, we did not notice fluctuation, while transillumination was not feasible. Performance of ultrasonography, including Doppler color flow imaging, followed, depicting a subcutaneous cystic lesion, 2.1⁎3.2 cm in dimensions, without extension to the thoracic cavity. Scheduled surgical excision of the lesion was decided. Histopathological examination documented the diagnosis of cystic lymphangioma. Patient is still followed up on a 6-month basis. He remains asymptomatic, after 2 years, without indication of relapse.

Paraesophageal Hernia as a Cause of Chronic Asymptomatic Anemia in a 6 Years Old Boy; Case Report and Review of the Literature.

Esophageal hiatal hernia is defined as the prolapse of one or more intra-abdominal organs through the esophageal hiatus. Four types are identified: type Ι or sliding hiatal hernia, type II or paraesophageal hernia (PEH), type III or mixed hernia and type IV. Congenital type II esophageal hiatal hernia is caused by a remaining gap after the formation of pleuroperitoneal membrane. We present a case of a six years old boy admitted to our department, appearing with asymptomatic anemia, who was incidentally diagnosed with Type II esophageal hiatal hernia. After diagnostic investigation, the prolapsing stomach pouch was reduced, the hernia sac was excised, the crura of diaphragm were converged and a total fundoplication was performed, via open method. The patient had an uncomplicated postoperative period. We conclude that: 1) esophageal hiatal hernia should be included within diagnostic approach of a child with chronic non-hereditary anemia, 2) after a Type II esophageal hiatal hernia is diagnosed, a hernia repair surgery is indicated in short time, due to the severity of possible complications and 3) through the performance of total fundoplication, it is secured that the subdiaphragmatic abdominal part of esophagus will be retained, preventing the development of post-operative gastroesophageal reflux disease.

Epididymal Adenomatoid Tumor: A Very Rare Paratesticular Tumor of Childhood.

Adenomatoid tumor is an uncommon benign mesothelial neoplasm, usually localized in the epididymis. It is the most common paratesticular tumor of middle-aged patients (average age of clinical presentation: 36 years). However, these tumors in pediatric and pubertal patients are extremely rare. Due to their rarity, we present a case of adenomatoid tumor of the tail of the epididymis in a 16-year-old patient. After systematic research of the current literature, we did not find another case report of epididymal adenomatoid tumor in a male patient aged 16 years old or less. This notice and our concern, as well, about the patient's surveillance protocol during the postoperative period were the motive for this case study.

Multiple Gastric Erosion Early after a 3 V Lithium Battery (CR2025) Ingestion in an 18-Month-Old Male Patient: Consideration about the Proper Time of Intervention.

Introduction. Button battery ingestion is considered an emergency situation in pediatric patients that needs to be managed promptly; otherwise, it may lead to serious and potentially lethal complications, especially when it is impacted in the esophagus. Less attention has been given in cases where the battery passes into the stomach, with guidelines for emergency intervention being based on the presence of symptoms. Case Report. We present a case of an 18-month-old male patient who presented to our emergency department after button battery ingestion. He did not have any symptoms and no pathological findings were encountered during clinical examination. X-ray investigation revealed the presence of the battery in the stomach. The patient was admitted for observation and two hours later he had two episodes of vomiting. He underwent urgent endoscopic removal of the battery where multiple acute gastric mucosal erosion in place of direct contact of the battery's negative pole with the mucosa of the gastric antrum was found. Conclusion. In specific cases the urgent endoscopic intervention for removal of an ingested button battery that is located in the stomach even in asymptomatic patients should be suggested.

Lower esophageal sphincter relaxation by administrating hyoscine-N-butylbromide for esophageal impaction by coin - shaped foreign bodies; prospective clinical study in pediatric population.

Aim of the present study is the presentation of our experience in conservative treatment of coin-shaped, ingested foreign bodies in lower esophagus and the consideration about the indications of this method's appliance in clinical practice. From 2011 to 2014, 79 children in total (45 male - 34 female), aged from 8 months to 13 years (average 4.8 years) were admitted to our Department due to foreign body ingestion. In 21/79 patients the foreign body lodged in the esophagus, in 9 in the upper and in 12 in the lower esophagus. Cases of pre-existing esophageal stricture or of esophageal obstruction, due to sharp or linear foreign bodies or disk battery, were excluded. Finally, our study group consisted of 11 patients, aged from 10 months to 10 years (aver- age 4.6 years). The average time elapsed from the ingestion of the foreign body until the admission of the child in the Emergency Department was 4 hours. Young patients were administered suppository form of hyoscine-N-butylbromide, followed by repetition of radiograph 6 hours later. In 9 cases the ingested foreign body passed to the stomach within the first six hours, while in 2 cases no alteration of its position was noted, thus endoscopic removal followed. In these 9 cases the foreign body passed through the gastrointestinal (GI) tract and was excreted within the next 1-3 days. Smooth muscle relaxation of the lower esophageal sphincter after administration of hyoscine-N-butylbromide was successful in 82% of our patients, while the success rate in relevant publications ranges from 20 to 42%. In conclusion, it is worth noting that the pharmaceutical relaxation of the lower esophageal sphincter is a safe alternative method of treatment in cases of foreign bodies lodged in the lower esophagus, except for linear or sharp objects or coin batteries. Given that the majority of hospitals in Northern Greece lacks of pediatric gastroenterologists, while endoscopic intervention - when indicated - should be conducted early after admission, it is obvious that the proposed method becomes essential.
