RESUMO
The technique of a single-port laparoscopy was developed over the last years as an attempt to lower surgical aggression and improve the aesthetic results of the minimally invasive surgery. A new robotic platform used with the da Vinci® Robotic System Single-Site System® (Intuitive Surgical, Sunnyvale, California, United States) was recently launched on the global market and is still not documented in Brazil. The authors report on the first four robotic single-port cholecystectomies performed with this da Vinci® Robotic System in Brazil.

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.

O transplante de intestino, ao redor do mundo, tem crescido de maneira sólida e consistente nos últimos 10 anos. No final da década de 1990, passou de um modelo experimental para uma prática clínica rotineira no tratamento dos pacientes com complicação severa da nutrição parenteral total com falência intestinal. Nos últimos anos, vários centros têm relatado uma crescente melhora nos resultados de sobrevida do transplante no primeiro ano (ao redor de 80%), porém, a longo prazo, ainda é desafiador. Diversos avanços permitiram sua aplicação clínica. O surgimento de novas drogas imunossupressoras, como o tacrolimus, além das drogas indutoras, os anticorpos antilinfocíticos mono e policlonal, nos últimos 10 anos, foi de suma importância para a melhora da sobrevida do transplante de intestino/multivisceral, mas, apesar dos protocolos bastante rígidos de imunossupressão, a rejeição é bastante frequente, podendo levar a altas taxas de perdas de enxerto a longo prazo. O futuro do transplante de intestino e multivisceral parece promissor. O grande desafio é reconhecer precocemente os casos de rejeição, prevenindo a perda do enxerto e melhorando os resultados a longo prazo, além das complicações causadas por infecções oportunistas, doenças linfoproliferativas pós-transplante e a doença do enxerto contra hospedeiro.

BACKGROUND: In recent years, there has been renewed interest in using robotics in bariatric surgery for the treatment of morbid obesity. However, the high cost of a robotic surgical system has hindered its widespread use in developing countries. This study aims to compare the rate of morbidity, weight loss, and relative costs between laparoscopic (LSG) and robotic-assisted sleeve gastrectomy (RSG) performed for the treatment of obesity in a single center in Brazil. METHODS: From January 2011 to March 2013, 48 severely obese patients underwent either LSG or RSG at our institution and were prospectively followed up for 12 months. Patients were free to choose either approach and were informed of any extra costs that may be incurred. RESULTS: Thirty-two patients underwent LSG and 16 patients, RSG. No significant differences were observed between LSG and RSG groups regarding age, sex, BMI, incidence of comorbidities, duration of surgery, and length of hospital stay. Also, there were no significant between-group differences in BMI values evaluated at 6 and 12 months after surgery. Surgical costs were almost twice as high and total hospital costs were approximately 50 % higher in the robotic approach compared to the laparoscopic approach. CONCLUSION: Both RSG and LSG had excellent and similar post-operative clinical outcomes. However, the much higher costs of purchasing and maintaining the robotic system are still precluding the use of RSG as a routine approach in the treatment of morbid obesity in Brazil.

BACKGROUND: Central pancreatectomy is an alternative technique for benign or low-grade malignant tumors. Laparoscopic central pancreatectomy has been rarely performed, with only 48 cases reported in the English literature. The aim of this paper was to review all published cases together with 3 cases from our institution. METHODS: All published articles indexed on PubMed were included. Terms used were "laparoscopic central pancreatectomy" or "laparoscopic middle pancreatectomy." Variables studied were the operative time, the type of reconstruction, indications, the use of robotic or hand assistance, blood loss, transfusion, pancreatic fistula, hospital stay, follow-up, development of exocrine and/or endocrine insufficiency, morbidity, and mortality. RESULTS: A total of 51 patients were identified. Twenty-one patients underwent total laparoscopy (41.2%), 27 required robotic assistance (52.9%), one required hand assistance (1.9%), and there were 2 conversions. In 18 cases (35.3%), pancreatic reconstruction involved a Roux-en-Y pancreatojejunostomy, and in 32 cases, pancreatogastrostomy (62.7%). The mean operative time was 356 minutes. Blood loss was minimal in most cases, and only 1 patient required blood transfusion (1.9%). Mortality was nil, but morbidity was high, mainly because of pancreatic fistula (46%). The mean hospital stay was 13.8 days. All patients underwent laparoscopic central pancreatectomy for benign or low-grade neoplasms. The mean follow-up duration was 19.6 months (range, 2 to 48 mo). No patient presented exocrine or endocrine insufficiency. CONCLUSIONS: Laparoscopic central pancreatectomy is a feasible and useful technique for the removal of tumors located in the neck of the pancreas. There are very few centers performing this operation, and therefore, a literature review was necessary to identify its indications and technical possibilities, and to promote its use.

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.
Ferimentos traumáticos do esôfago não iatrogênicos são de difícil manejo clínico e requerem condutas individualizadas e cuidadosas. Frente à baixa incidência dessa afecção, a maioria dos centros não possui experiência suficiente para a definição de uma conduta padronizada para o manejo de tais lesões. O tratamento conservador da perfuração do esôfago permanece um tema controverso, embora relatos mais recentes tenham documentado sua eficácia, especialmente após a perfuração, em pacientes que não apresentam outras lesões associadas, instabilidade hemodinâmica ou sinais de sepse. É apresentado aqui o caso de um paciente com ferimento por projétil no esôfago cervical tratado exclusivamente com manejo conservador, tendo sido realizados drenagem da lesão, suporte nutricional por meio de sonda nasoenteral e antibioticoterapia, com evolução satisfatória.

Os tumores estromais do trato gastrintestinal, embora relativamente raros, compreendem a maioria dos tumores mesenquimais do trato digestivo e constituem 5% de todos os sarcomas. Quanto à apresentação clínica, os sintomas mais comuns são dor, hemorragia digestiva e massa palpável. Este trabalho relatou o caso de um paciente jovem que desenvolveu hemoperitôneo por ruptura de neoplasia gástrica e necessitou de tratamento cirúrgico de urgência. A análise patológica e imunoistoquímica revelou tratar-se de um caso raro epidemiologicamente: tipo celular epitelioide e c-KIT negativo.
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.

The aim of this study was to report our experience in robotic-assisted surgery of hiatus hernia and gastroesophageal reflux disease in a large series of complex cases. From March 2009 until July 2010, 21 patients were operated due to hiatus hernia or reflux disease using robotic-assisted surgery at Albert Einstein Hospital, São Paulo, Brazil. All patients were selected for the robotic approach because of the complexity of the cases (associated co-morbidity) such as: previous major upper abdominal surgery in 6 patients, hiatus hernia with paraesophageal involvement in 8 patients, obesity with a body mass index of over 29 kg/m(2) in 8 patients, and previous hiatus hernioplasty in 3 patients. Optimal trocar positioning, operating and setup times, conversion rate, intraoperative complications, and perioperative morbidity and mortality rate were analyzed. The mean operating time was reduced from 316 to 195 min after five procedures and the setup time from 20 to 10 min after five procedures. There were no conversions in this group of patients and also no complication or need of blood transfusion. Robotic-assisted fundoplication is feasible, safe and effective for treating hiatus hernias and gastroesophageal reflux disease, especially in complex cases because improved dissection in the esophageal hiatus region compensates for long operating times. Disadvantages are the high costs, the time to master the setup/system, and the necessity of exact trocar positioning.
RESUMO
In the last few years, robotic surgery has started to take its place in pancreatic surgery. Robotic surgery provides advantages such as enhanced visualisation and freedom of dissection within a confined space and also allows economical surgery. The aim of this study was to evaluate the feasibility, safety and short-term outcome of the robotic approach using the da Vinci robotic system in pancreatic/peripancreatic tumors other than pancreatic carcinomas. Fifteen patients with eight intraductal papillary mucinous neoplasms, four pancreatic neuroendocrine and three periampulary tumors were included in this initial series. Seven left pancreatectomies, five pancreatoduodenectomies and two total pancreatectomies were performed at Albert Einstein Hospital, São Paulo, Brazil. The mean operating room time for all the procedures was 503 min (315-775 min). Blood transfusion was necessary in one patient (3 units). The mean length of stay for all patients was 16 days (5-52 days). Large series of robotic pancreatic surgery should be described and the decision as to its routine use will come from cumulative experience. This surgical system allows difficult procedures to be performed more easily, effectively and precisely.
