Introduction: The ingestion of foreign bodies is usually accidental and asymptomatic, it is observed more frequently in patients with psychiatric diseases, children and older adults, being able to cause gastric perforation in 1% of cases. Clinical case: A 70-year-old male patient who comes to the emergency due to severe pain located in the epigastrium, with the presence of a palpable, painful mass with irregular edges. Discussion: the preoperative diagnosis of hollow viscera perforation by a foreign body must take into account the epidemiological history, directed interrogation, physical examination and paraclinical studies to allow its differentiation with other medical or surgical entities, allowing the appropriate preoperative and intraoperative management of the patient. Conclusion: In spite of the infrequent, the perforation of hollow viscera by foreign body should be a differential diagnosis to be considered by the general surgeon.

Introduction: This article describes an assembly system that transforms a smartphone into a portable endoscopic mobile unit and it's compared to a conventional endoscopic device.Objective: to evaluate use of smartphones in innovation in healthcare by analing image quality using an adaptation of a smartphone as a video device to perform laparoscopy, and comparing it with an HD laparoscope to check the feasibility of use in future.Materials and methods: comparative, simply blinded, experimental study that describes an adaptation of a portable laparoscopic device and a system to evaluate the image quality and comparing it with a conventional HD laparoscope.Results: in the evaluation of the overall quality of the video, statistically both videos are of equal quality. Conclusion:the smartphone coupled to an endoscopic camera as a video device for performing laparoscopy has a similar quality to a conventional HD laparoscopic device in vitro; wich would allow the following use of this system to perform laparoscopic procedures with a safe, secure and cost effectively device.
