RESUMEN
BACKGROUND: One of the primary complications associated with large incisions in abdominal surgery is the increased risk of fascial closure rupture and incisional hernia development. The choice of the fascial closure method and closing with minimal tension and trauma is crucial for optimal results, emphasizing the importance of uniform pressure along the suture line to withstand intra-abdominal pressure. AIMS: To evaluate the resistance to pressure and tension of stapled and sutured hand-sewn fascial closure in the abdominal wall. METHODS: Nine abdominal wall flaps from human cadavers and 12 pigs were used for the experimentation. An abdominal defect was induced after the resection of the abdominal wall and the creation of a flap in the cadaveric model and after performing a midline incision in the porcine models. The models were randomized into three groups. Group 1 was treated with a one-layer hand-sewn small bite suture, Group 2 was treated with a two-layer hand-sewn small bite suture, and Group 3 was treated with a two-layer stapled closure. Tension measurements were assessed in cadaveric models, and intra-abdominal pressure was measured in porcine models. RESULTS: In the human cadaveric model, the median threshold for fascial rupture was 300N (300-350) in Group 1, 400N (350-500) in Group 2, and 350N (300-380) in Group 3. Statistical comparisons revealed non-significant differences between Group 1 and Group 2 (p=0.072, p>0.05), Group 1 and Group 3 (p=0.346, p>0.05), and Group 2 and Group 3 (p=0.184, p>0.05). For porcine subjects, Group 1 showed a median pressure of 80 mmHg (85-105), Group 2 had a median of 92.5 mmHg (65-95), and Group 3 had a median of 102.5 mmHg (80-135). Statistical comparisons indicated non-significant differences between Group 1 and Group 2 (p=0.243, p>0.05), Group 1 and Group 3 (p=0.468, p>0.05), and Group 2 and Group 3 (p=0.083, p>0.05). CONCLUSIONS: Stapled and conventional suturing resist similar pressure and tension thresholds.

BACKGROUND: Patients with abdominal site cancer are at risk for incisional hernia after open surgery. This study aimed to compare the short- and long-term outcomes of robotic-assisted (RVIHR) with the laparoscopic incisional hernia repair (LVIHR) in an oncologic institute. METHODS: This is a single-blinded randomized controlled pilot trial. Patients were randomized into two groups: RVIHR and LVIHR. RESULTS: Groups have similar baseline characteristics (LVIHR: N = 19; RVIHR: N = 18). No difference was noted in the length of hospital stay (RVIHR: 3.67 ± 1.78 days; LVIHR: 3.95 ± 2.66 days) and postoperative complications (16.7 versus 10.5%; p = 0.94). The mean operating time for RVIHR was significantly longer than LVIHR (RVIHR was 355.6 versus 293.5 min for LVIHR; p = 0.04). Recurrence was seen in three patients in LVIHR and two in RVIHR at 24-month follow-up, with no significant difference. (p > 0.99). CONCLUSION: Laparoscopic and robotic-assisted incisional hernia repair show similar short- and long-term outcomes for cancer patients.

BACKGROUND: Robotic-assisted surgery research has grown dramatically in the past two decades and the advantages over traditional videolaparoscopy have been extensively debated. For hernias, the robotic system can increase intraoperative strategies, especially in complex hernias or incisional hernias. AIMS: This study aimed to compare the direct cost differences between robotic and laparoscopic hernia repair and determine each source of expenditure that may be related to the increased costs in a robotic program from the perspective of a Brazilian public institution. METHODS: This study investigated the differences in direct costs from the data generated from a trial protocol (ReBEC: RBR-5s6mnrf). Patients with incisional hernia were randomly assigned to receive laparoscopic ventral incisional hernia repair (LVIHR) or robotic ventral incisional hernia repair (RVIHR). The direct medical costs of hernia treatment were described in the Brazilian currency (R$). RESULTS: A total of 19 patients submitted to LVIHR were compared with 18 submitted to RVIHR. The amount spent on operation room time (RVIHR: 2,447.91±644.79; LVIHR: 1,989.67±763.00; p=0.030), inhaled medical gases in operating room (RVIHR: 270.57±211.51; LVIHR: 84.55±252.34; p=0.023), human resources in operating room (RVIHR: 3,164.43±894.97; LVIHR: 2,120.16±663.78; p<0.001), material resources (RVIHR: 3,204.32±351.55; LVIHR: 736.51±972.32; p<0.001), and medications (RVIHR: 823.40±175.47; LVIHR: 288.50±352.55; p<0.001) for RVIHR was higher than that for LVIHR, implying a higher total cost to RVIHR (RVIHR: 14,712.24±3,520.82; LVIHR: 10,295.95±3,453.59; p<0.001). No significant difference was noted in costs related to the hospital stay, human resources in intensive care unit and ward, diagnostic tests, and meshes. CONCLUSION: Robotic system adds a significant overall cost to traditional laparoscopic hernia repair. The cost of the medical and robotic devices and longer operative times are the main factors driving the difference in costs.

BACKGROUND: Robotic gastrectomy (RG) has been shown to be a safe and feasible method in gastric cancer (GC) treatment. However, most studies are in Eastern cohorts and there is great interest in knowing whether the method can be used routinely, especially in the West. OBJECTIVES: The aim of this study was to compare the short-term surgical outcomes of D2-gastrectomy by RG versus open gastrectomy (OG). METHODS: Single-institution, open-label, non-inferiority, randomized clinical trial performed between 2015 and 2020. GC patients were randomized (1:1 allocation) to surgical treatment by RG or OG. Da Vinci Si platform was used. INCLUSION CRITERIA: gastric adenocarcinoma, stage cT2-4 cN0-1, potentially curative surgery, age 18-80 years, and ECOG performance status 0-1. EXCLUSION CRITERIA: emergency surgery and previous gastric or major abdominal surgery. Primary endpoint was short-term surgical outcomes. The study is registered at clinicaltrials.gov (NCT02292914). RESULTS: Of 65 randomized patients, 5 were excluded (3 palliatives, 1 obstruction and emergency surgery, and 1 for material shortage). Consequently, 31 and 29 patients were included for final analysis in the OG and RG groups, respectively. No differences were observed between groups regarding age, sex, BMI, comorbidities, ASA, and frequency of total gastrectomy. RG had similar mean number of harvested lymph nodes (p = 0.805), longer surgical time (p < 0.001), and less bleeding (p < 0.001) compared to OG. Postoperative complications, length of hospital stay, and readmissions in 30 days were equivalent between OG and RG. CONCLUSIONS: RG reduces operative bleeding by more than 50%. The short-term outcomes were non-inferior to OG, although surgical time was longer in RG.

BACKGROUND: Trocars position for the Si model (position is similar for the Xi, although trocars stay more in line). Robotic gastrectomy is gaining popularity worldwide. It allows reduced blood loss and lesser pain. However, it widespread use is limited by the extensive learning curve and costs. AIM: To describe our standard technique with reduced use of robotic instruments. METHODS: We detail the steps involved in the procedure, including trocar placement, necessary robotic instruments, and meticulous surgical description. RESULTS: After standardizing the procedure, 28 patients were operated with this budget technique. For each procedure material used was: 1 (Xi model) or 2 disposable trocars (Si) and 4 robotic instruments. Stapling and clipping were performed by the assistant through an auxiliary port, limiting the use of robotic instruments and reducing the cost. CONCLUSION: This standardization helps implementing a robotic program for gastrectomy in the daily practice or in one`s institution.

RESUMEN
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is currently the most frequently performed bariatric procedure in Turkey. The goal of weight reduction surgery is not only to decrease excess weight, but also to improve obesity related comorbidities and quality of life (QoL). AIM: To evaluate the impact of LSG on patient quality of life, weight loss, and comorbidities associated with morbid obesity according to the updated BAROS criteria. METHODS: Eleven hundred thirty-eight adult patients were undergone to LSG by our bariatric surgery team between January 2013 and January 2016. A questionnaire (The Bariatric Analysis and Reporting Outcome System - BAROS) was published on social media. The data on postoperative complications were collected from hospital database. RESULTS: Number of respondants was 562 (49.4%). Six of 1138 patients(0.5%) had leakage. All patients who had leakage were respondants. The overall complication rate was 7.7%. After a mean period of 7.4±5.3 months(1-30), mean excess weight loss was 71.3±27.1% (10.2-155.4). The respondants reported 772 comorbidities. Of these, 162 (30%) were improved, and 420 (54.4%) were resolved. The mean scores for QoL were significantly increased after LSG (range, p<0.05 to <0.001). Of the 562 patients, 26 (4.6%) were classified as failures; 86 (15.3%) fair; 196 (34.9%) good; 144 (25.6%) very good, and 110 (19.6%) excellent results according to the updated BAROS scoring system. CONCLUSION: LSG is a highly effective bariatric procedure in the manner of weight control, improvement in comorbidities and increasing of QoL in short- and mid-term.

Patients with diabetes and coronary artery disease are frequently considered for myocardial revascularization procedures, aiming at cardiovascular events risk reduction and a better quality of life. In clinical practice, decisions concerning surgery or percutaneous coronary intervention are frequently difficult, because of cases' severity, disease extension and co-morbidities association. Beyond that, the bulk of literature information was generated by subgroup analysis of randomized clinical trials, which were designed for the general population, not for diabetics. The aim of this study was to review literature on coronary percutaneous intervention in diabetic patients, and also to show recent data from the experience in this procedure at the Catheterization Laboratory of the Cardiology Institute of RS.

RESUMO RACIONAL: A pesquisa em cirurgia robótica assistida cresceu dramaticamente nas últimas duas décadas e as vantagens sobre a videolaparoscopia tradicional têm sido amplamente debatidas. Para as hérnias, o sistema robótico pode aumentar as estratégias intraoperatórias, principalmente em hérnias complexas ou hérnias incisionais. OBJETIVOS: Comparar as diferenças de custo direto entre a hernioplastia incisional robótica e a laparoscópica e determinar cada fonte de gasto que pode estar relacionada ao aumento de custos em um programa de robótica na perspectiva de uma instituição pública brasileira. MÉTODOS: Investigar as diferenças nos custos diretos dos dados gerados a partir de um protocolo de ensaio clínico (ReBEC: RBR-5s6mnrf). Pacientes com hérnia incisional foram aleatoriamente designados para serem submetidos a reparo robótico ou laparoscópico (RVIHR). Os custos foram descritos na moeda brasileira (R$). RESULTADOS: Dezenove pacientes submetidos à cirurgia robótica foram comparados com dezoito submetidos à cirurgia laparoscópica. O valor gasto com tempo de centro cirúrgico (Robótica: 2.447,91±644,79; Robótica: 1.989,67±763,00; p=0,030), gases medicinais inalados em centro cirúrgico (Robótica: 270,57±211,51; Robótica: 84,55±252,34; p=0,023), recursos humanos em centro cirúrgico (Robótica: 3.164,43±894,97; Laparoscópica: 2.120,16±663,78; p<0,001), recursos materiais (Robótica : 3.204,32±351,55; Robótica: 736,51±972,32; p<0,001) e medicamentos (Robótica: 823,40±175,47; Robótica: 288,50 ± 352,55; p<0,001) para cirurgia robótica foi maior que cirurgia laparoscópica, implicando em maior custo total para cirurgia robótica (Robótica: 14.712,24±3.520,82; Laparoscópica: 10.295,95±3.453,59; p<0,001). Não foi observada diferença significativa nos custos relacionados à permanência hospitalar, recursos humanos em UTI e enfermaria, exames diagnósticos e telas. CONCLUSÕES: O sistema robótico adiciona um custo global significativo à hernioplastia incisional laparoscópica tradicional. O custo dos dispositivos médicos e robóticos, além de tempos cirúrgicos mais prolongados, são os principais fatores que impulsionam a diferença nos custos.
RESUMEN
BACKGROUND: Ventriculoperitoneal (VP) shunt is a day-to-day procedure performed by a neurosurgeon. The most frequent associated complications are obstructive and infectious. Although rare, there are well-reported complications related to the poor positioning of the distal catheter, with perforation of organs and tissues. Still rarer are the complications related to the migration of this catheter. CASE DESCRIPTION: We describe an atypical case of VP shunt postoperative by normal pressure hydrocephalus. After well-documented proper positioning of the distal catheter into the intraperitoneal cavity, it protruded into the subcutaneous space. Even on a new documented satisfactory abdominal tomography, this catheter migrated back again to the subcutaneous tissue. CONCLUSION: We did not find plausible explanation for this rare event.

BACKGROUND: The laparoscopic ventral hernia repair technique made possible surgeries with smaller skin incisions and smaller dissection of the soft tissue around the hernia, therefore with a better wound, a quicker postoperative recovery and a lower complication rate. AIM: To evaluate the applicability of a quality of life survey based on the molds of the American Hernia Society, European Hernia Society and Carolinas Equation for Quality of Life, through telephone in patients submitted to laparoscopic hernioplasty by IPOM technique. METHODS: A retrospective cohort study was made to evaluate the quality of life of 21 patients that underwent anterior abdominal wall laparoscopic hernioplasty by intraperitoneal onlay mesh technique. Questionnaire was applied through telephone. RESULTS: Of the 21 patients, 19% felt that the hernia recurred. Also 19% passed through another abdominal wall surgery, and among these, 75% was related to the previously hernia correction. Finally, 81% of patients did not undergo any other abdominal wall surgery. CONCLUSION: It was possible to apply the quality of life questionnary by telephone on patients who underwent an anterior abdominal wall. The results, in its turn, were satisfactory and showed that patients, in general, were satisfied with the surgical procedure.

INTRODUCTION: Minimally invasive videosurgery has modified anatomy dissection of diseases that are treated operatively. However, the benefit of this method has been delayed due to the lack of development of technologies and articulated movements for the abdominal wall, demanding the need for investments and time for solidification. This approach to repair the abdominal wall is based on the Rives-Stoppa principles. TECHNIQUE: With the patient in supine position, a small supra pubic incision is done and the pre-peritoneal space is achieved and inflated. After the trocars are placed, the peritoneal sac is dissected and the abdominal cavity is entered, above the arcuate line. The posterior rectus sheath is liberated and a linear stapler is placed in both sides and fired, creating a midline and a retromuscular space, where the mesh is placed and fixed. CONCLUSION: The method is feasible, easy to perform, reproducible, saves time and with a good functional result.

BACKGROUND: Robotic brought to laparoscopy the enrichment of movements, the easy to perform maneuvers and procedures, visualization in three dimensions, and ergonomics for the surgeon. AIM: To describe Brazilian experience with robotically-assisted abdominal surgery. METHODS: From July 2008 to April 2010, patients were admitted for abdominal surgery and agreed to being operated with the help of the robot by a trained medical staff. All patients were operated by the same surgical robotic approach. Time required for complete surgery, and console time, were recorded. RESULTS: Forty-four patients were operated, most for hernial hiatal correction or bariatric surgery. All patients, except one, were discharged in the day after surgery. The only complication was a fistula due to a videolaparoscopic clamping procedure during bariatric surgery. There was no hemorrhage. No re-operation was necessary, neither conversion to laparoscopic or open surgery. Mean surgery time for the whole sample was 249.7 minutes (4.1 hours) and console time was 153.4 minutes (2.5 hours). Patients' blood lost was minimal. CONCLUSIONS: Robotically assisted abdominal surgery is safe for the patients, with reduced bleeding and acceptable surgical time, and also ergonomic for the surgeons.

BACKGROUND: Minimally invasive techniques have been revolutionary and provide clinical evidence of decreased morbidity and comparable efficacy to traditional open surgery. Computer-assisted surgical devices have recently been approved for general surgical use. AIM: The aim of this study was to report the first known case of pancreatic resection with the use of a computer-assisted, or robotic, surgical device in Latin America. PATIENT AND METHODS: A 37-year-old female with a previous history of radical mastectomy for bilateral breast cancer due to a BRCA2 mutation presented with an acute pancreatitis episode. Radiologic investigation disclosed an intraductal pancreatic neoplasm located in the neck of the pancreas with atrophy of the body and tail. The main pancreatic duct was enlarged. The surgical decision was to perform a laparoscopic subtotal pancreatectomy, using the da Vinci robotic system (Intuitive Surgical, Sunnyvale, CA). Five trocars were used. Pancreatic transection was achieved with vascular endoscopic stapler. The surgical specimen was removed without an additional incision. RESULTS: Operative time was 240 minutes. Blood loss was minimal, and the patient did not receive a transfusion. The recovery was uneventful, and the patient was discharged on postoperative day 4. CONCLUSIONS: The subtotal laparoscopic pancreatic resection can safely be performed. The da Vinci robotic system allowed for technical refinements of laparoscopic pancreatic resection. Robotic assistance improved the dissection and control of major blood vessels due to three-dimensional visualization of the operative field and instruments with wrist-type end-effectors.

The surgical robotic system is superior to traditional laparoscopy in regards to 3-dimensional images and better instrumentations. Robotic surgery for hepatic resection has not yet been extensively reported. The aim of this paper is to report the first known case of liver resection with use of a computer-assisted, or robotic, surgical device in Latin America. A 72-year-old male with cryptogenic liver cirrhosis and hepatocellular carcinoma was referred for surgical treatment. Preoperative clinical evaluation and laboratory data disclosed a Child-Pugh class A patient. Magnetic resonance imaging showed a 2.2 cm tumor in segment 5. Liver size was decreased and there were signs of portal hypertension, such as splenomegaly and enlarged portal vein collaterals. Preoperative upper digestive endoscopy disclosed esophageal varices. Five trocars were used. Liver transection was achieved with harmonic scalpel and bipolar forceps. Hemostasis of raw surface areas was accomplished with interrupted stitches. Operative time was 120 minutes. Blood loss was minimal and the patient did not receive transfusion. The recovery was uneventful and patient was discharged on the 3rd postoperative day without ascites formation. Laparoscopic hepatic resection can safely be performed. The laparoscopic approach may enable liver resection in patients with cirrhosis and evidence of liver failure that would contraindicate open surgery probably because it precludes the transection of major abdominal collaterals. The Da Vinci robotic system allowed for technical refinements of laparoscopic liver resection due to 3-dimensional visualization of the operative field and instruments with wrist-type end-effectors.
