Isolated rupture of the gallbladder following blunt abdominal trauma: case report.

ABSTRACT 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.

Hemoperitôneo secundário a GIST gástrico c-KIT negativo e anticorpo anti-DOG1 positivo

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.

Intestinal and multivisceral transplantation

Intestinal transplantation has shown exceptional growth over the past 10 years. At the end of the 1990’s, intestinal transplantation moved out of the experimental realm to become a routine practice in treating patients with severe complications related to total parenteral nutrition and intestinal failure. In the last years, several centers reported an increasing improvement in survival outcomes (about 80%), during the first 12 months after surgery, but long-term survival is still a challenge. Several advances led to clinical application of transplants. Immunosuppression involved in intestinal and multivisceral transplantation was the biggest gain for this procedure in the past decade due to tacrolimus, and new inducing drugs, mono- and polyclonal anti-lymphocyte antibodies. Despite the advancement of rigid immunosuppression protocols, rejection is still very frequent in the first 12 months, and can result in long-term graft loss. The future of intestinal transplantation and multivisceral transplantation appears promising. The major challenge is early recognition of acute rejection in order to prevent graft loss, opportunistic infections associated to complications, post-transplant lymphoproliferative disease and graft versus host disease; and consequently, improve results in the long run.

Conservative treatment in isolated penetrating cervical esophageal injury: case report

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 of injuries, and who are hemodynamically stable and non-septic. We report a case of a patient sustaining a single cervical gunshot wound compromising the cervical esophagus and who was treated exclusively with cervical drainage, enteral support and antibiotics.
