EUS-CDS and EUS-HGS have equal efficacy and safety, and are both associated with a very high technical and clinical success. The choice of approach may be selected based on patient anatomy.

Steatotic liver grafts were used on a large scale (71%) in this clinical series. The analysis confirms that using grafts with moderate (>30%) and severe steatosis (>60%) have a negative impact on outcomes. The authors conclude that using these grafts allow a significant increase in organ offer that counterbalances the negative outcome for patients who are not offered a transplant, and this supports the need for further clinical research.

BACKGROUND: Fascial dehiscence (FD) occurs in up to 14.9% of high-risk patients undergoing emergency laparotomy. Although prophylactic mesh can prevent FD, its use in emergency operations remains controversial. STUDY DESIGN: A prospective randomized clinical trial was conducted at the Hospital das Clínicas from Faculdade de Medicina da Universidade de São Paulo in Brazil. It was performed among highrisk patients, defined according to Rotterdam risk model, undergoing midline emergency laparotomy. The patients were randomized into the suture group (SG), with slowly absorbable running sutures placed with a 36-mm-long needle at a suture-to-wound length ratio of 4:1, and the prophylactic mesh group (PMG), with fascial closure as in the SG but reinforced with onlay polypropylene mesh. The primary end point was incidence of FD at 30 days post operation. RESULTS: We analyzed 115 patients; 52 and 63 were allocated to the SG and PMG, respectively. In all, 77.4% of the cases were for colorectal resection. FD occurred in 7 (13.5%) patients in the SG and none in the PMG (p ¼ 0.003). There was no difference between the groups in number of patients with surgical site occurrence (SSO) or SSO requiring procedural intervention. However, some specific SSOs had higher incidences in the mesh group: surgical site infection (20.6% versus 7.7%; p ¼ 0.05), seroma (19.0% versus 5.8%; p ¼ 0.03), and nonhealing incisional wound (23.8% versus 5.8%; p ¼ 0.008). Of SSOs in the PMG and SG, 92.3% and 73.3%, respectively, resolved spontaneously or with bedside interventions. CONCLUSIONS: Prophylactic onlay mesh reinforcement in emergency laparotomy is safe and prevents FD. Surgical site infection, seroma, and nonhealing incisional wound were more common in the mesh group, but associated with low morbidity within 30 days post operation.

Occult ischemia of the mobilized stomach is usually related to the dehiscence of an esophagogastric anastomosis. The principle of ischemic conditioning was studied to verify its clinic use. This study aims to evaluate progressively the tissue perfusion of the stomach in ischemic conditioning, establishing the best moment for gastric transposition. Twenty-four male EPM-1 Wistar rats were used, which also underwent partial desvacularization of the stomach by ligature of the left gastric vessels. Tissue perfusion was measured through flowmetry by laser Doppler (tissue perfusion unit; TPU) in the antrum (10 mm distal from the cardiac region). This measurement was done before (baseline) and immediately after the ligature, and on different postoperative days (POD) (days 3, 7, 10, and 14). A statistical analysis was done with nonparametric tests (P

Hypertonic saline and pentoxifylline, both alone and in combination, attenuated oxidative stress and the activation of NF-κB, leading to a decrease in the inflammatory response.

Microsurgical techniques have been applied in many surgical specialties and have also a broad application in surgical research. It demands high technical skills and continued training. The microsurgical training is lengthy, very expensive and demands high commitment. The microsurgical skills should be first mastered in the lab and only then applied in the clinic. Here, we propose a model of a training course in microsurgery. We also suggest that surgical societies involved with microsurgery promote training courses on a regular basis. Key words: Microsurgery. Teaching. Education. Motor Skills. RESUMOMicrocirurgia tornou-se uma técnica aplicável em uma série de especialidades cirúrgicas e em pesquisa experimental. Microcirurgia exige alta qualidade técnica e treinamento contínuo. No Brasil, existe grande carência de microcirurgiões devido aos custos envolvidos no treinamento e na escassez de serviços que ofereçam treinamento especializado. O treinamento em microcirurgia é longo, caro e exige alto grau de dedicação. O completo domínio das técnicas de microcirurgia deve ser obtido primeiro no laboratório antes de ser empregada na prática clínica. Nesse artigo, propõe-se um modelo de curso teórico-prático em microcirurgia. Também sugere-se que sociedades de especialidades cirúrgicas mais ligadas à microcirurgia fomentem a capacitação de profissionais em microcirurgia através da realização de cursos básicos em microcirurgia.
