ABSTRACT
INTRODUCTION: Bronchogenic cysts (BCs) are rare congenital lesions that originate from the tracheobronchial bud and can be found in any organ derived from the embryonic foregut. Complete surgical excision is the treatment of choice, and the definitive diagnosis is established by histopathological examination. PRESENTATION OF THE CASE: 41-year-old female with diastolic arterial hypertension and a heterogeneous mass, with multiple calcifications and a solid component with well-defined regular contours. A biochemical study revealed no functionality. Intraoperatively we noticed an adrenal gland-dependent mass with a cystic component and an area of sebaceous content and histological examination confirmed a bronchogenic cyst. DISCUSSION: The majority of cases of BCs are asymptomatic. They can be intrapulmonary, mediastinal or ectopic, being the left adrenal region the most common retroperitoneal location. Symptomatic cysts should always be surgically resected either by thoracotomy or a minimally invasive technique, which has been shown to improve postoperative discomfort and shorten hospital stay with reliable postoperative outcomes. CONCLUSION: Despite their low incidence, it is important to consider BCs in the differential diagnosis of retroperitoneal masses, particularly in the left para-adrenal region.
ABSTRACT
INTRODUCTION: Gastrointestinal stromal tumors (GIST) are infrequent, and clinical presentation varies between asymptomatic and diffuse symptoms such as abdominal pain and dyspepsia. Surgical approach depends on location and size of the tumor. There are some reports of the specific surgical approach for GIST located at the gastroesophageal junction. This is a case report of a patient with a GIST located specifically at the gastroesophageal junction and the surgical approach selected for the treatment. PRESENTATION OF THE CASE: A 70-year-old patient who developed an episode of upper gastrointestinal bleeding with hemorrhagic shock accompanied by elevated troponins that required transfusion therapy and whose endoscopic evaluation showed a subcardial ulcerated lesion of 16 × 5 mm, located 2 cm below the z-line. The lesion was biopsied and was negative for malignancy. A combined surgical approach for resection by combined laparoscopy and submucosal resection by upper gastrointestinal endoscopy was performed by the interventional gastroenterology service and surgical oncology service. DISCUSSION: Specific management of GISTs depends on the location of the tumor, even though, complete surgical resection remains the gold standard treatment. Minimally invasive techniques can be used to assess these tumors leading to shorter hospital stays and lesser risk of complications. Laparoendoscopic cooperative surgery is a promising approach for managing lesions near the gastroesophageal junction. CONCLUSION: GISTs located near the gastroesophageal junction require a complex approach. The laparaendoscopic approach seems to be a feasible approach for GIST in the gastroesophageal junction.
