ABSTRACT Objective To evaluate a method aimed at teaching ultrasound techniques to medical students in emergency settings. Methods A prospective study conducted with 66 sixth-year undergraduate medical students. Students participated in theory and practicing sessions with a 5-hour load; knowledge acquisition was assessed through pre- and post-course and 90-day tests. A questionnaire were distributed to the students after course completion for theoretical and practical knowledge assessment. Results Average pre-test grade in theoretical content evaluation was 4.9, compared to 7.6 right […]

Gallbladder rupture following blunt abdominal trauma is a rare event recognized on evaluation and treatment of other visceral injuries during laparotomy. Isolated gallbladder rupture secondary to blunt abdominal trauma is even more uncommon. The clinical presentation of gallbladder injury is variable, resulting in a delay in diagnosis and treatment. We report the case of a patient who suffered an isolated gallbladder rupture due to blunt abdominal trauma.

Non-iatrogenic traumatic cervical esophageal perforations are usually hard to manage in the clinical setting, and often require a careful and individualized approach. The low incidence of this particular problem leads to a restricted clinical experience among most centers and justify the lack of a standardized surgical approach. Conservative treatment of esophageal perforation remains a controversial topic, although early and sporadic reports have registered the efficacy of non-operative care, especially following perforation in patients that do not sustain any other kind […]

Although relatively rare, the gastrointestinal stromal tumors comprise most mesenchymal tumors of the digestive tract and account for 5% of all sarcomas. The most common symptoms are pain, gastrointestinal bleeding and palpable mass. This study reported the case of a young patient who developed hemoperitoneum due to gastric neoplasm rupture and required urgent surgical treatment. Pathology and immunohistochemistry analysis showed an epidemiologically rare case: epithelioid and c-KIT negative tumor.
