Duodenal Rupture after Blunt Abdominal Trauma by Bicycle Handlebar: Case Report and Literature Review.

Blunt abdominal trauma is most frequent in the pediatric population. Duodenal lesions after abdominal trauma in children are infrequent and tend to be secondary to traffic accidents. It is up to five times more frequent in males, with an average age between 16 and 30 years. Bicycle accidents continue to lead to morbidity and mortality in children, representing between 5% and 14% of total blunt abdominal injuries. The diagnosis of duodenal injuries after trauma is difficult and requires a high index of clinical suspicion. We present the case of a 17-year-old patient seen in the emergency room after falling off his bicycle and presented a blunt trauma in the epigastric region. On physical examination, there was a swelling in the upper right abdominal quadrant and epigastrium with tenderness on deep palpation. He presented with hematemesis without hemodynamic repercussion. A contrast abdominal computed tomography was performed and he was diagnosed with third-part duodenal rupture. A resection of the perforated third-part duodenal rupture was performed, and the transit was reconstructed using a Roux-Y duodenojejunostomy. The postoperative period was uneventful and the patient was discharged after 16 days of stay. Duodenal injury is very rare, produced by high-energy trauma. They rarely present as single lesions as other visceral lesions are usually associated. The early diagnosis is important to reduce the morbidity and mortality.

Primary Hyperparathyroidism due to Parathyroid Adenoma Originated from Supernumerary Gland.

INTRODUCTION: The variability of the location of the parathyroid glands is directly related to the events that occur during embryonic development. The impact that an individual submits more than four parathyroid glands is close to 13%. However the presentation of a parathyroid adenoma in a supernumerary gland is an uncommon event. CASE REPORT: A 30-year-old man diagnosed with primary hyperparathyroidism with matching findings on ultrasonography and scintigraphy for parathyroid adenoma localization lower left regarding the thyroid gland. A cervicotomy explorer showed four orthotopic parathyroid glands. The biopsy of the inferior left gland was normal. No signs of adenoma were seen in the biopsy. Following mobilization of the ipsilateral thyroid lobe, fifth parathyroid gland was found increased significantly in size than proceeded to remove, confirming the diagnosis of adenoma. After the excision, the levels of serum calcium and parathyroid hormone were normalized. CONCLUSIONS: The presentation of a parathyroid adenoma in a supernumerary gland is a challenge for the surgeon. The high sensitivity having different imaging techniques has been a key to locate preoperatively the pathological parathyroid gland. Analytical or clinical persistence of primary hyperparathyroidism after parathyroid surgery can occur if the location of the adenoma is a supernumerary or ectopic gland location.
