INTRODUCTIONA Bochdalek hernia is a posterior congenital defect of the diaphragm, usually on the left hemidiafragm, caused by a lack of closure of the pleuroperitoneal canal between the eighth and tenth week of fetal life during the embryonic development. It typically presents in the neonatal period with severe respiratory failure.PRESENTATION OF CASEIn this paper we present a 35 year old man with a 5-year history of episodes of severe dyspnea who arrived to the emergency room, during his medical work-up we incidentally found an intrathoracic gastric bubble, a laparoscopy was performed, founding a necrotic stomach and for defect correction.DISCUSSIONThis pathology is infrequent in adults, among this age group, there are two different clinical presentations: asymptomatic patients who are diagnosed incidentally when abdominal organs are found in the thorax in a chest X-ray, and symptomatic patients due to side effects of incarceration, strangulation, hemorrhage and visceral perforation in the chest cavity.CONCLUSIONDiaphragmatic hernias are rare among adult population, and they are usually asymptomatic, in this case we presented a symptomatic patient, diagnosed with a chest X-ray and treated surgically. The surgical approach for the resolution of this pathology is variable and it depends on the presence and severity of visceral complications.

Background. Duodenal neuroendocrine tumours are very rare, if they are limited to the mucosal layer and have no nodal involvement, endoscopic resection may be curative. Case report. We present the case of a Mexican 52 years old female with a duodenal neuroendocrine tumour who underwent successful endoscopic submucosal dissection with no complications. Pathology of the specimen revealed a complete R0 resection with negative resection margins. Endoscopic biopsies 4 weeks later showed no malignant cells. Conclusions. Because of their low frequency the management of primary duodenal carcinoid tumours is controversial; for tumours less than 1 cm endoscopic resection is recommended, for those bigger than 2 cm surgical resection is advised. Management of tumours between 1 and 2 cm is controversial and should be individualized.
