Abdominal esophagocardiectomy with esophagogastric anastomosis, with vagal preservation and construction of a spiral anti reflux valve in the treatment of advanced megaesophagus.

Objective: present a new operative technique characterized by abdominal esophagocardiectomy, with esophagogastrus anastomosis, vagal preservation and spiral anti-reflux valve construction in the treatment of advanced megaesophagus in patients with severe systemic diseases, as well as its result in an initial group of 17 patients.

Method: We selected 17 patients with advanced megaesophagus and comorbidities submitted to new technique. The following parameters were analyzed: age, sex, length of hospital stay, early and late complications, mortality, radiological/endoscopic aspects.

Managing tube thoracostomy with thoracic ultrasound: results from a randomized pilot study.

Purpose: Tube thoracostomy (TT) is a simple and a life-saving procedure; nevertheless, it carries morbidity, even after its removal. Currently, TT is managed and removed by chest X-ray (CXR) evaluation. There are limitations and these are directly linked to complications.

Comparative study of abdominal cavity temporary closure techniques for damage control.

The damage control surgery, with emphasis on laparostomy, usually results in shrinkage of the aponeurosis and loss of the ability to close the abdominal wall, leading to the formation of ventral incisional hernias. Currently, various techniques offer greater chances of closing the abdominal cavity with less tension. Thus, this study aims to evaluate three temporary closure techniques of the abdominal cavity: the Vacuum-Assisted Closure Therapy - VAC, the Bogotá Bag and the Vacuum-pack.

Open abdomen in gastrointestinal surgery: Which technique is the best for temporary closure during damage control?

Aim: To compare the 3 main techniques of temporary closure of the abdominal cavity, vacuum assisted closure (vacuum-assisted closure therapy - VAC), Bogota bag and Barker technique, in damage control surgery.

Methods: After systematic review of the literature, 33 articles were selected to compare the efficiency of the three procedures. Criteria such as cost, infections, capacity of reconstruction of the abdominal wall, diseases associated with the technique, among others were analyzed.

LIVER TRANSPLANTATION AFTER SEVERE HEPATIC TRAUMA: CURRENT INDICATIONS AND RESULTS.

Background: The liver is the most injured organ in abdominal trauma. Currently, the treatment in most cases is non-operative, but surgery may be necessary in severe abdominal trauma with blunt liver damage, especially those that cause uncontrollable bleeding. Despite the damage control approaches in order to achieve hemodynamic stability, many patients develop hypovolemic shock, acute liver failure, multiple organ failure and death.

Complications after Radiofrequency Ablation of 233 Hepatic Tumors.

Objective: The only curative treatment for primary and secondary hepatic malignancies is surgery and liver transplantation. Thus, the majority of the patients are not candidates for resection, and there is a lack of organs. For these reasons, alternative treatment modalities such as radiofrequency ablation (RFA) are employed.

Complications of radiofrequency ablation of hepatic tumors: Frequency and risk factors.

Radiofrequency ablation (RFA) has become an important option in the therapy of primary and secondary hepatic tumors. Surgical resection is still the best treatment option, but only a few of these patients are candidates for surgery: multilobar disease, insufficient liver reserve that will lead to liver failure after resection, extra-hepatic disease, proximity to major bile ducts and vessels, and co-morbidities. RFA has a low mortality and morbidity rate and is considered to be safe.

Torsion of a wandering spleen treated with partial splenectomy and splenopexy.

Background: Wandering spleen is a rare and unusual entity, characterized by excessive mobility and displacement of the organ from its normal position. This happens due to congenital or acquired anomalies leading to the lack of the spleen's suspensory ligaments. Clinical presentation is variable; acute abdominal pain may occur when persistent torsion of the splenic pedicle results in splenic infarction.

Spleen preserving distal pancreatectomy in an isolated blunt pancreatic trauma.

Blunt isolated pancreatic trauma is uncommon, accounting for 1%-4% of high impact abdominal injuries. In addition, its diagnosis can be difficult; physical signs may be poor and laboratory findings nonspecific, resulting in delayed treatment. Preserving the spleen during distal pancreatectomy (DP) is controversial.

Esophagectomy for a traumatic esophageal perforation with delayed diagnosis.

Esophageal perforations are rare, and traumatic perforations are even more infrequent. Due to the rarity of this condition and its nonspecific presentation, the diagnosis and treatment of this type of perforation are delayed in more than 50% of patients, which leads to a high mortality rate. An 18-year-old male patient was brought to the emergency room with a penetrating neck injury, caused by a gunshot wound.

An unusual approach to the spontaneous rupture of hepatocellular carcinoma.

Our aim is to describe an unusual approach to the spontaneous rupture of a large hepatocellular carcinoma (HCC). A 45-year-old man, Hepatitis C virus (+) (HCV+), complaining of abdominal pain. During the investigation, a tumor affecting liver segments V, VI, VII and VIII, with the presence of fluid within the peritoneal cavity, suggesting hemoperitoneum, was found.

Radiofrequency ablation of primary and metastatic liver tumors--4 years experience.

Background/aims: Radiofrequency ablation of primary and metastatic liver tumors has been shown to be one of the promising new modalities to treat or to palliate liver tumors. It has been used as a bridge to liver transplantation as well as an approach to recurrent tumors after resection.

Methodology: We present a series of 78 cases, 39 females and 39 males with a mean age of 61 years, the RFA has been used either by laparotomy or percutaneously to treat 117 lesions.
