Abstract
BACKGROUND Robot-assisted gastrectomy (RG) has been shown to be safe and feasible in the treatment of gastric cancer (GC). However, it is unclear whether RG is equivalent to laparoscopic gastrectomy (LG), especially in the Western world. Our objective was to compare the outcomes of RG and LG in GC patients. METHODS We reviewed all gastric adenocarcinoma patients who underwent curative gastrectomy by minimally invasive approach in our institution from 2009 to 2022. Propensity score matching (PSM) analysis was conducted to reduce selection bias. DaVinci Si platform was used for RG. RESULTS A total of 156 patients were eligible for inclusion (48 RG and 108 LG). Total gastrectomy was performed in 21.3% and 25% of cases in LG and RG, respectively. The frequency of stage pTNM II/III was 48.1%, and 54.2% in the LG and RG groups (p = 0.488). After PSM, 48 patients were matched in each group. LG and RG had a similar number of dissected lymph nodes (p = 0.759), operative time (p = 0.421), and hospital stay (p = 0.353). Blood loss was lower in the RG group (p = 0.042). The major postoperative complications rate was 16.7% for LG and 6.2% for RG (p = 0.109). The 30-day mortality rate was 2.1% and 0% for LG and RG, respectively (p = 1.0). There was no significant difference between the LG and RG groups for disease-free survival (79.6% vs. 61.2%, respectively; p = 0.155) and overall survival (75.9% vs. 65.7%, respectively; p = 0.422). CONCLUSION RG had similar surgical and long-term outcomes compared to LG, with less blood loss observed in RG.

Abstract
This review evaluated the risks and survival benefits of pancreatoduodenectomy associated with venous resection compared with palliative surgery. A systematic review with meta-analysis was performed. Higher overall survival was observed in the pancreatic resection group (HR = 4.000; 95% CI 2.800 to 5.200). However, the palliative group had fewer complications (RD = -0.170; 95% CI -0.260 to -0.070). There was no significant difference in the mortality rates (RD = 0.000; 95% CI -0.030 to 0.030). In centres with experience in pancreatic surgery, resection may be considered for locally advanced cancer and major venous invasion. Pancreaticoduodenectomy with vascular resection may improve survival for periampullary tumours compared with palliation therapy. However, pancreaticoduodenectomy with major venous resection has potentially higher morbidity than palliation therapy. Key Words: Pancreatoduodenectomy, Pancreatic neoplasms, Vascular surgical procedures.

Abstract
BACKGROUND Peritoneal carcinomatosis in gastric cancer is considered a fatal disease, without expectation of definitive cure. As systemic chemotherapy is not sufficient to contain the disease, a multimodal approach associating intraperitoneal chemotherapy with surgery may represent an alternative for these cases. AIMS The aim of this study was to investigate the role of intraperitoneal chemotherapy in stage IV gastric cancer patients with peritoneal metastasis. METHODS This study is a single institutional single-arm prospective clinical trial phase II (NCT05541146). Patients with the following inclusion criteria undergo implantation of a peritoneal catheter for intraperitoneal chemotherapy: Stage IV gastric adenocarcinoma; age 18-75 years; Peritoneal carcinomatosis with peritoneal cancer index<12; Eastern Cooperative Oncology Group 0/1; good clinical status; and lab exams within normal limits. The study protocol consists of four cycles of intraperitoneal chemotherapy with paclitaxel associated with systemic chemotherapy. After treatment, patients with peritoneal response assessed by staging laparoscopy undergo conversion gastrectomy. RESULTS The primary outcome is the rate of complete peritoneal response. Progression-free and overall survivals are other outcomes evaluated. The study started in July 2022, and patients will be screened for inclusion until 30 are enrolled. CONCLUSIONS Therapies for advanced gastric cancer patients have been evaluated in clinical trials but without success in patients with peritoneal metastasis. The treatment proposed in this trial can be promising, with easy catheter implantation and ambulatory intraperitoneal chemotherapy regime. Verifying the efficacy and safety of paclitaxel with systemic chemotherapy is an important progress that this study intends to investigate.

Abstract
BACKGROUND Albumin-bilirubin (ALBI) score is an indicator of liver dysfunction and is useful for predicting prognosis of hepatocellular carcinomas. Currently, this liver function index has been used to predict prognosis in other neoplasms. However, the significance of ALBI score in gastric cancer (GC) after radical resection has not been elucidated.
AIM To evaluate the prognostic value of the preoperative ALBI status in patients with GC who received curative treatment.
METHODS Patients with GC who underwent curative intended gastrectomy were retrospectively evaluated from our prospective database. ALBI score was calculated as follows: (log10 bilirubin × 0.660) + (albumin × -0.085). The receiver operating characteristic curve with area under the curve (AUC) was plotted to evaluate the ability of ALBI score in predicting recurrence or death. The optimal cutoff value was determined by maximizing Youden’s index, and patients were divided into low and high-ALBI groups. The Kaplan-Meier curve was used to analyze the survival, and the log-rank test was used for comparison between groups.
RESULTS A total of 361 patients (235 males) were enrolled. The median ALBI value for the entire cohort was -2.89 (IQR -3.13; -2.59). The AUC for ALBI score was 0.617 (95%CI: 0.556-0.673, P < 0.001), and the cutoff value was -2.82. Accordingly, 211 (58.4%) patients were classified as low-ALBI group and 150 (41.6%) as high-ALBI group. Older age (P = 0.005), lower hemoglobin level (P < 0.001), American Society of Anesthesiologists classification III/IV (P = 0.001), and D1 lymphadenectomy P = 0.003) were more frequent in the high-ALBI group. There was no difference between both groups in terms of Lauren histological type, depth of tumor invasion (pT), presence of lymph node metastasis (pN), and pathologic (pTNM) stage. Major postoperative complication, and mortality at 30 and 90 days were higher in the high-ALBI patients. In the survival analysis, the high-ALBI group had worse disease-free survival (DFS) and overall survival (OS) compared to those with low-ALBI (P < 0.001). When stratified by pTNM, the difference between ALBI groups was maintained in stage I/II and stage III CG for DFS (P < 0.001 and P = 0.021, respectively); and for OS (P < 0.001 and P = 0.063, respectively). In multivariate analysis, total gastrectomy, advanced pT stage, presence of lymph node metastasis and high-ALBI were independent factors associated with worse survival.
CONCLUSION The preoperative ALBI score is able to predict the outcomes of patients with GC, where high-ALBI patients have worse prognosis. Also, ALBI score allows risk stratification of patients within the same pTNM stages, and represents an independent risk factor associated with survival.

Abstract
Resulting from impaired collagen turnover, fibrosis is a hallmark of adipose tissue (AT) dysfunction and obesity-associated insulin resistance (IR). Prolidase, also known as peptidase D (PEPD), plays a vital role in collagen turnover by degrading proline-containing dipeptides but its specific functional relevance in AT is unknown. Here we show that in human and mouse obesity, PEPD expression and activity decrease in AT, and PEPD is released into the systemic circulation, which promotes fibrosis and AT IR. Loss of the enzymatic function of PEPD by genetic ablation or pharmacological inhibition causes AT fibrosis in mice. In addition to its intracellular enzymatic role, secreted extracellular PEPD protein enhances macrophage and adipocyte fibro-inflammatory responses via EGFR signalling, thereby promoting AT fibrosis and IR. We further show that decreased prolidase activity is coupled with increased systemic levels of PEPD that act as a pathogenic trigger of AT fibrosis and IR. Thus, PEPD produced by macrophages might serve as a biomarker of AT fibro-inflammation and could represent a therapeutic target for AT fibrosis and obesity-associated IR and type 2 diabetes.

Abstract
AIM Salvage surgery (SS) is defined as surgical resection after the failure of the first treatment with curative intent. The aim of this study was to report the experience of a reference center with SS for stomach adenocarcinoma. METHODS This is a retrospective study of patients with gastric cancer (GC) operated on between 2009 and 2020. RESULTS Notably, 40 patients were recommended for salvage gastrectomy with curative-intent treatment. For analysis purpose, patients were divided into two groups: 23 patients after endoscopic resection and 17 patients after gastrectomy. In the first group, all patients underwent R0 resection, their average hospital length of stay (LOS) was 15.7 days, and 2 (8.6%) patients had major complications. During the average follow-up of 37.2 months, there was only one recurrence. The median overall survival (OS) was 46 months. In the postgastrectomy group, 9 (52.9%) patients were rescued with curative intent, the average hospital LOS was 12.2 days, and 3 (17.6%) had major complications. In a mean follow-up of 22 months, five patients relapsed. Median OS and disease-free survival were 24 and 16.5 months, respectively. CONCLUSION SS in GC offers the possibility of long-term disease control and increased survival rate with an acceptable complication rate.

Abstract
INTRODUCTION although it is a rare disease, common variable immunodeficiency (CVID) stands out as the most frequent primary symptomatic immunodeficiency. Carriers are prone to a variety of recurrent bacterial infections, in addition to the risk of developing autoimmune diseases and neoplasms including gastric cancer (GC). Despite the recognized risk, there are no specific standardized protocols for the management of GC in these patients, so the reported oncological results are varied. Thus, this study aims to describe the clinicopathological characteristics and prognosis of patients with CVID undergoing surgical treatment of GC. METHODS all patients with GC undergoing surgical treatment between 2009 and 2020 were retrospectively evaluated. Later, patients diagnosed with CVID were identified and this group was compared with the remaining patients without any immunodeficiency. RESULTS among the 1101 patients with GC evaluated in the period, 10 had some type of immunodeficiency, and 5 were diagnosed with CVID. Patients with CVID had younger age, lower BMI, and smaller lesions compared to those without CVID. Four patients underwent curative gastrectomy and one patient underwent jejunostomy. Two patients died (1 palliative and 1 curative) and one patient had disease recurrence. There was no statistically significant difference regarding the incidence of postoperative complications and survival between the evaluated groups. CONCLUSION the CVID incidence in patients with GC undergoing surgical treatment was 0.5%, occurring at a less advanced age, but with no difference regarding surgical and oncological results.

Abstract
BACKGROUND Clinical stage IV gastric cancer (GC) may need palliative procedures in the presence of symptoms such as obstruction. When palliative resection is not possible, jejunostomy is one of the options. However, the limited survival of these patients raises doubts about who benefits from this procedure. AIM To create a prognostic score based on clinical variables for 90-d mortality for GC patients after palliative jejunostomy. METHODS We performed a retrospective analysis of Stage IV GC who underwent jejunostomy. Eleven preoperative clinical variables were selected to define the score categories, with 90-d mortality as the main outcome. After randomization, patients were divided equally into two groups: Development (J1) and validation (J2). The following variables were used: Age, sex, body mass index (BMI), American Society of Anesthesiologists classification (ASA), Charlson Comorbidity index (CCI), hemoglobin levels, albumin levels, neutrophil-lymphocyte ratio (NLR), tumor size, presence of ascites by computed tomography (CT), and the number of disease sites. The score performance metric was determined by the area under the receiver operating characteristic (ROC) curve (AUC) to define low and high-risk groups. RESULTS Of the 363 patients with clinical stage IVCG, 80 (22%) patients underwent jejunostomy. Patients were predominantly male (62.5%) with a mean age of 62.4 years old. After randomization, the binary logistic regression analysis was performed and points were assigned to the clinical variables to build the score. The high NLR had the highest value. The ROC curve derived from these pooled parameters had an AUC of 0.712 (95%CI: 0.537-0.887, P = 0.022) to define risk groups. In the validation cohort, the diagnostic accuracy for 90-d mortality based on the score had an AUC of 0.756, (95%CI: 0.598-0.915, P = 0.006). According to the cutoff, in the validation cohort BMI less than 18.5 kg/m2 (P < 0.001), CCI ≥ 1 (P = 0.001), ASA III/IV (P = 0.002), high NLR (P = 0.012), and the presence of ascites on CT exam (P = 0.004) were significantly associated with the high-risk group. The risk groups showed a significant association with first-line (P = 0.012), second-line chemotherapy (P = 0.009), 30-d (P = 0.013), and 90-d mortality (P < 0.001). CONCLUSION The scoring system developed with 11 variables related to patient's performance status and medical condition was able to distinguish patients undergoing jejunostomy with high risk of 90 d mortality.

Abstract
Gastric cancer (GC) is one of the most lethal malignancies and Gastrectomy with D2 lymphadenectomy is considered the standard surgical treatment. Adequate lymph node dissection is necessary for patients' prognosis, but D2 lymphadenectomy is technically demanding due to the complexity of anatomy, even more so if performed laparoscopically. The learning curve requires a high degree of training with a considerable number of cases and standardization of the technique. Recently, Indocyanine Green (ICG) and Near-Infrared (NIR) Fluorescence Imaging have been presented as promising image-guided surgery techniques, providing real-time anatomy assessment and intra-operative visualization of blood flow, lymph nodes and lymphatic vessels. ICG fluorescence imaging has been studied in GC surgery, especially for real-time lymphatic mapping. At present, we are conducting a prospective, open-label, single-arm clinical trial (Clinical trial - NCT03021200) to evaluate the feasibility and outcomes of ICG and NIR Fluorescence Imaging in GC surgery. In this technical note, we present one approach to the use of this technique to guide lymphadenectomy in laparoscopic distal gastrectomy.

Abstract
Background: Remnant gastric cancer (RGC) is increasing due to past use of subtotal gastrectomy to treat benign diseases, improvements in the detection of gastric cancer, and increased survival rates after gastrectomy for gastric cancer. Laparoscopic access provides the advantages and benefits of minimally invasive surgery. However, laparoscopic completion total gastrectomy (LCTG) for RGC is technically demanding, even for experienced surgeons. Because of its rarity and heterogeneity, no standard surgical strategy has been established and few surgeons will develop technical expertise to carry out this procedure. Aim: To describe our standard technique, giving surgeons a head start in LCTG and report the early experience with this stepwise approach. Materials and Methods: We detail all the steps involved in the procedure, including trocar placement and surgical description. Results: Between 2009 and 2019, a total of 8 patients with past history of RGC were operated with this technique. All patients had been previously operated by open method, 7 due to peptic ulcer disease and 1 due to gastric cancer. Their mean age at the time of the first surgery was 38.9 years (range 25-56 years) and the mean interval between the first and the second gastrectomy was 32.1 years (range 13.6-49). Billroth II was the previous reconstruction in all cases. A 5-trocar technique was used followed by total gastrectomy with side-to-side stapled intracorporeal esophagojejunostomy anastomosis and Roux-en-Y reconstruction. The mean operation time was 272 minutes (range 180-330) and median blood loss was 247 mL (range 50-500). There was no conversion and no major intraoperative complication. Major postoperative complications occurred in 3 patients. Conclusion: Completion total gastrectomy for RGC is a morbid procedure and laparoscopic access is technically feasible, hopefully carrying the benefits of faster recovery, reduced postoperative pain, and wound complications. By standardizing the approach, the learning curve may be shortened and better results achieved.

Abstract
BACKGROUND Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) represent a rare tumor composed of adenocarcinoma and neuroendocrine carcinoma components. This study reports a case series of gastric MiNEN and discusses issues related to its diagnosis, management, and outcomes. METHODS We retrospectively analyzed data from patients with gastric MiNEN who underwent surgical resection at our service from 2009 to 2020. Patients with gastric adenocarcinoma served as a comparison group. Clinical, pathologic, and surgical characteristics were compared. RESULTS During the selected period, 5 gastric MiNEN patients and 597 patients with gastric adenocarcinoma were included. Among the clinical variables, age, sex, BMI, and laboratory exams were similar between the two groups. Only ASA classification was different (p = 0.015). Pathological variables such as tumor size, lymphovascular invasion, number of retrieved lymph nodes, and pTNM staging were also similar between both groups. Lastly, early surgical outcomes and long-term survival did not differ between gastric MiNEN and adenocarcinoma patients. CONCLUSION A MiNEN is a rare tumor that represents less than 1% of GC patients undergoing curative treatment, and demonstrated clinicopathological characteristics and outcomes similar to gastric adenocarcinoma.

Abstract
BACKGROUND Epstein-Barr virus (EBV) positive gastric cancer (GC) has been described as a distinct molecular subtype of the disease, especially associated with gastric carcinoma with lymphoid stroma (GCLS). The possibility that EBV associated GC (EBVaGC) had better prognosis and may be susceptible to immunotherapy has increased the interest in this subtype. However, immune checkpoint and survival of EBVaGC are still controversial, especially with regard to GCLS and conventional gastric adenocarcinoma (CGA). This study aimed to evaluate the clinicopathological characteristics, immunohistochemical profiles and prognosis of EBVaGC according to the histological type GCLS and CGA. METHODS we retrospectively evaluated a series of EBVaGC who underwent gastrectomy with D2-lymphadenectomy. Biomarkers and tumor-infiltrating cells were evaluated by immunohistochemistry. PD-L1 was evaluated using a combined positive score (CPS). RESULTS From a total of 30 EBVaGC, 14 (46.7%) were identified as GCLS and 16 (53.3%) as CGA (9 Intestinal, 6 diffuse, 1 undetermined). There were no significant differences in age, sex, and pTNM between GCLS and CGA. CPS-positivity and high-CD8+ was significantly higher in GCLS compared with CGA (P = 0.007 and P = 0.005, respectively). Diffuse EBVaGC had worse survival than intestinal type (P = 0.020). There was no difference in survival between GCLS and intestinal CGA (P = 0.260). In multivariate analysis, CPS and pN status were related with survival in EBVaGC. CONCLUSIONS CGLS was associated with a predominance of CD8+ cell infiltration and PD-L1 expression. CPS and lymph node metastasis were independent factors associated with prognosis in EBVaGC. These results suggest that specifically EBV-positive GCLS may be prime candidates for PD-1 directed therapy.

Abstract
BACKGROUND D2 lymphadenectomy for gastric cancer is technically demanding and requires clearance of the lymph node stations along the main arteries that irrigate the stomach and the liver. As gastric and hepatic irrigation have a different pattern from the classic branching of the celiac trunk in approximately 25% of patients, acquaintance with these variations and knowledge on how to adequately perform the lymphadenectomy in different anatomic settings is of utmost importance for surgeons who manage gastric cancer.1 METHODS: This video demonstrates, step-by-step, how to perform D2 lymphadenectomy in accordance with gastric and hepatic irrigation. Illustrations of the arterial variation correlate with the corresponding computed tomography image and operative management of the lymph node stations. DISCUSSION D2 lymphadenectomy is the standard of care in advanced gastric cancer.2 It implies clearing the lymph node stations along the celiac trunk, left gastric artery, and common and proper hepatic arteries. However, the celiac trunk and hepatic irrigation are highly variable and surgeons must be aware of how to properly and safely address the lymph node stations in all scenarios. Vessel anatomical variations increase the risk of vascular injuries and its complications, such as bleeding, necrosis, liver function impairment, liver necrosis, and conversion to open surgery.3-5 Additionally, the lymphadenectomy cannot be compromised if a variation is found.6 Preoperative knowledge of the gastric blood supply also shortens the surgical duration.7 CONCLUSIONS: The present video demonstrates how to recognize the most common variations found during D2 gastrectomy, and provides strategies to adequately approach them.

Abstract
BACKGROUND Remnant gastric cancer (RGC) is defined as a tumor that develops in the stomach after a previous gastrectomy and is generally associated with a worse prognosis. However, there little information available regarding RGCs and their prognostic factors and survival.
AIM To evaluate the clinicopathological characteristics and prognosis of RGC after previous gastrectomy for benign disease.
METHODS Patients who underwent curative resection for primary gastric cancer (GC) at our institute between 2009 and 2019 were retrospectively evaluated. All RGC resections with histological diagnosis of gastric adenocarcinoma were enrolled in this study. Primary proximal GC (PGC) who underwent total gastrectomy was selected as the comparison group. Clinical and pathological data were collected from a prospective medical database.
RESULTS A total of 41 patients with RGC and 120 PGC were included. Older age (P = 0.001), lower body mass index (P = 0.006), hemoglobin level (P < 0.001), and number of resected lymph nodes resected (LN) (P < 0.001) were associated with the RGC group. Lauren type, pathological tumor-node-metastasis, and perioperative morbimortality were similar between RGC and PGC. There was no difference in disease-free survival (P = 0.592) and overall survival (P = 0.930) between groups. LN status was the only independent factor related to survival.
CONCLUSION RGC had similar clinicopathological characteristics to PGC. Despite the lower number of resected LN, RGC had a similar prognosis.

Abstract
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.

Abstract
BACKGROUND The octogenarian population is expanding worldwide and demand for gastrectomy due to gastric cancer in this population is expected to grow. However, the outcomes of surgery with curative intent in this age group are poorly reported and it is unclear what matters most to survival: age, clinical status, disease´s stage, or the extent of the surgery performed. AIM Evaluate the results of gastrectomy in octogenarians with gastric cancer and to verify the factors related to survival. METHODS From prospective database, patients aged 80 years or older with histologically confirmed adenocarcinoma who had undergone gastrectomy with curative intent were selected. Factors related to postoperative complications and survival were studied. RESULTS Fifty-one patients fulfilled the inclusion criteria. A total of 70.5% received subtotal gastrectomy and in 72.5% D1 lymphadenectomy was performed. Twenty-five (49%) had complications, in eleven major complications occurred (seven of these were clinical complications). Hospital length of stay was longer (8.5 vs. 17.8 days, p=0.002), and overall survival shorter (median of 1.4 vs. 20.5 months, p=0.009) for those with complications. D2 lymphadenectomy and the presence of postoperative complications were independent factors for worse overall survival. CONCLUSION Octogenarians undergoing gastrectomy with curative intent have high risk for postoperative clinical complications. D1 lymphadenectomy should be the standard of care in these patients.

Abstract
BACKGROUND As age advances, a higher burden of comorbidities and less functional reserve are expected, however, the impact of aging in the surgical outcomes of gastric cancer (GC) patients is unknown. OBJECTIVE The aim of this study is to evaluate surgical outcomes of GC patients according to their age group. METHODS Patients submitted to gastrectomy with curative intent due to gastric adenocarcinoma were divided in quartiles. Each group had 150 patients and age limits were: ≤54.8, 54.9-63.7, 63.8-72, >72. The outcomes assessed were: postoperative complications (POC), 90-day postoperative mortality, disease-free survival (DFS) and overall survival (OS). RESULTS Major surgical complications were 2.7% in the younger quartile vs 12% for the others (P=0.007). Major clinical complications raised according to the age quartile: 0.7% vs 4.7% vs 5.3% vs 7.3% (P<0.042). ASA score and age were independent risk factors for major POC. The 90-day mortality progressively increased according to the age quartile: 1.3% vs 6.0% vs 7.3% vs 14% (P<0.001). DFS was equivalent among quartile groups, while OS was significantly worse for those >72-year-old. D2 lymphadenectomy only improved OS in the three younger quartiles. Age >72 was an independent risk factor for worse OS (hazard ratio of 1.72). CONCLUSION Patients <55-year-old have less surgical complications. As age progresses, clinical complications and 90-day mortality gradually rise. OS is worse for those above age 72, and D2 lymphadenectomy should be individualized after this age.

Abstract
INTRODUCTION In the future, surgery will be centralized in hospitals with the best value (excellent results with reduced cost). High-performance teams will be required; however, available data concerning the specific abilities necessary to build and manage them are poor. OBJECTIVES Share the set of competencies and skills established to build and lead a high-performance general surgery team. METHODS In November 2012, a general surgery team started its activities at a tertiary hospital in Sao Paulo, Brasil. The model consisted of high volume performed by a small team. Experienced surgeons, motivated, and with technical and moral excellence were selected. A sense of unity was created and goals were shared. Complex cases were discussed daily and a prospective database to follow outcomes was established. The payment value was above the market. RESULTS In 6 years and 4 months, 11,006 surgical procedures were performed (8,597 electives and 2,409 in an urgent setting). Cholecystectomy was the most common procedure (4,101; being 3,676 electives), followed by inguinal hernioplasty (n: 1,827) and appendectomy (n: 925). A total of 449 elective oncologic procedures were performed. The surgical site infection rate in clean procedures was 0.12%, 80 patients required re-do surgery (2.4% in an urgent setting and 0.2% of the electives). There were 22 postoperative deaths (0.66% for urgent and 0.07% for electives), 5 of the 6 deaths in elective patients were in oncologic cases. CONCLUSION A competent surgical team, inserted in a model that favors performance and values the individual can deliver high volume with exceptional results.

Abstract
BACKGROUND Multivisceral resection (MVR) is indicated in T4b gastric cancer (GC) when R0 can be achieved. Patient's selection for MVR is imperative, since it carries an increased risk for postoperative complications (POC) and disease recurrence. This study aims to elaborate prediction scores for POC and recurrence after MVR for cT4b GC. METHODS Patients who underwent MVR with curative intent due to cT4b gastric adenocarcinoma were selected from our prospective database. Scoring models were based on the variables identified as risk factors for the studied outcome. Through binary regression the model that best predicted the outcome was created. RESULTS From 237 MVRs, 58 fulfilled the inclusion criteria. Males were 70.7%, mean age was 61.8 years. A pT4b was confirmed in 34 patients, 29 had 2 or more adjacent organs removed. Major POC occurred in 25.9%, mortality was 8.6%. Overall survival (OS) and disease-free survival (DFS) were similar for pT4b and non-pT4b. DFS was worse for pN+ and when >2 adjacent organs were removed. Scoring models included 5 and 6 parameters for POC and recurrence, respectively, and their accuracy was 80.6% (95%CI = 0.69-0.92) and 78% (95%CI = 0.66-0.90). The POC and recurrence rates in low- and high-score groups were statistically different (p < 0.001 and p = 0.004, respectively). Patients with high-risk for POC had lower OS (p = 0.036) and DFS was worse in the high-recurrence risk group (p = 0.008). CONCLUSION The proposed scoring systems accurately predict POC and recurrence in GC patients undergoing MVR. These models are easy to use and can assist in the adoption of an individualized approach.

Abstract
BACKGROUND AND OBJECTIVE Neoadjuvant chemotherapy (nCMT) has been increasingly used in advanced gastric cancer (GC). However, the prognostic impact of tumor response remains unclear. This study aimed to evaluate if tumor response at the primary site and lymph nodes (LN) correlate with survival in GC patients after nCMT. METHODS Patients with gastric adenocarcinoma treated with nCMT followed by gastrectomy were evaluated. Residual tumor was graded from 0% to 100%, defining two groups: poor (PR) and major response (MR). LN regression rate (LNRR) was determined based on tumor/fibrosis examination at each LN and a cutoff value established by receiver operating characteristic curve. RESULTS Among 62 cases, 20 (32.2%) had MR and 42 (67.7%) PR. Smaller size, diffuse histology, lower ypT status and less advanced stage were associated with the MR group. Based on cutoff value of 57, 45.6% and 54.4% patients were classified as low-LNRR and high-LNRR. High-LNRR correlated with absence of venous, lymphatic and perineural invasion, and less advanced stage. Survival was equivalent between MR and PR (P = .956). High-LNRR had better disease-free survival (DFS) than low-LNRR (P < .001). In multivariate analysis, only LNRR associated with DFS. CONCLUSION High-LNRR associates with DFS in GC treated with nCMT. Response at the primary site does not correlate with survival.

Abstract
BACKGROUND AND OBJECTIVE Neoadjuvant chemotherapy (NACT) followed by radical surgery represents a treatment option for patients with advanced gastric cancer (GC). This case-control study aimed to evaluate the clinicopathological characteristics and surgical outcomes of GC patients who received NACT, and its impact on survival. METHODS We retrospectively reviewed all patients with GC who underwent gastrectomy. A total of 45 cases with NACT were matched with consecutive 45 patients who underwent upfront gastrectomy for the following characteristics: gender, age, gastrectomy type, lymphadenectomy extent, American Society of Anesthesiologists class, histological type, cT and cN. RESULTS NACT group had smaller tumors (4.9 vs 6.8 cm P = .006), lower lymphatic invasion rate (40% vs 73.3%, P = .001), lower venous invasion rate (18% vs 46.7%, P = .003) and lower perineural invasion rate (35% vs 77.8%, P < .0001). The ypTNM stage was lower in patients treated with NACT (P < .001). The major postoperative complication (POC) rate was lower in NACT patients (6.7% vs 24.4%, P = .02), as was hospital length of stay (10.8 vs 17 days, P = .005). CONCLUSIONS NACT allowed nodal and tumor downstaging. In addition, patients who underwent NACT had fewer POC and shorter length of hospital stay.

Abstract
Robotic surgery through the da Vinci Surgical System has been widely spread for many procedures across the globe for several years. At the same time, robot-assisted gastrectomy for gastric cancer (GC) remains mostly available only in specialized centers in minimally invasive surgery and stomach neoplasm. The robotic platform has been introduced to overcome possible drawbacks of the laparoscopic approach. The safety and the feasibility of robotic radical gastrectomy have been reported in many retrospective case series and nonrandomized prospective studies. However, the superiority of robotic gastrectomy over the laparoscopic access has not yet been proven. This study aimed to report the technical aspects of robot-assisted gastrectomy for GC as well as the latest evidence on this subject.

Abstract
BACKGROUND remnant gastric cancer (RGC) develops five years or later after previous resection for benign or malignant lesion. The treatment is performed through completion total gastrectomy (CTG) with radical lymphadenectomy. Some reports consider this procedure may be associated with higher rates of morbidity and mortality. OBJECTIVE to evaluate surgical results and survival after CTG in patients with RGC. METHODS 54 patients who underwent CTG between 2009 and 2019 were included in the study. As a comparison group 215 patients with primary gastric cancer (PGC) who underwent total gastrectomy (TG) in the same period were selected. RESULTS among the initial characteristics, age (68.0 vs. 60.5; p<0.001), hemoglobin values (10.9 vs. 12.3; p<0.001) and body mass index (22.5 vs. 24.6; p=0.005) were different between the RGC and PGC groups, respectively. The most frequent postoperative complications were related to pulmonary complications, infection and fistula in both groups. There was a higher incidence of esophagojejunal fistula in the CTG group (14.8% vs 6.5%, p=0.055). Perioperative mortality was higher in RGC patients (9.3% vs. 5.1%), but without significance (p=0.329). Hospital length of stay, postoperative complications graded by the Clavien-Dindo classification, mortality at 30 and 90 days were not different between groups. There was no significant difference in disease-free and overall survival between RGC and PGC groups. CONCLUSION despite previous reports, surgical results and survival were similar between groups. Higher risk of esophagojejunal fistula must be considered.

Abstract
BACKGROUND Postoperative chemotherapy (CMT) or chemoradiotherapy (CRT) is commonly recommended for gastric cancer (GC) patients in order to improve survival. However, some factors that prevent patients from return to intended oncologic treatment (RIOT) may increase the risk of recurrence and decrease the survival benefits achieved with curative resection. The aim of this study was to determine the frequency and factors associated with inability to RIOT and their impact on survival. METHODS This retrospective study included stage II/III GC patients treated with potentially curative gastrectomy. Patients who could return to intended oncologic treatment (RIOT group) and those who could not (inability to RIOT group) were analyzed. RESULTS Of the 313 eligible GC patients, 89 (28.4%) and 85 (27.2%) patients receive CRT and CMT, respectively, representing a RIOT rate of 55.6%. The main reason was attributed to general poor performance status (30.2%), followed by surgical postoperative complications (POC) (20.1%). Older age, higher ASA, D1 lymphadenectomy, and major POC were related to inability to RIOT. Older age, neutrophil-lymphocyte ratio (NLR), and major POC were independent risk factors for inability to RIOT. Five-year DFS and OS were worse for the inability to RIOT group than for the RIOT group (p = 0.008 and p = 0.004, respectively). In multivariate analyses, absence of neoadjuvant therapy, total gastrectomy, pT3/T4, pN+, and inability to RIOT were associated with worse DFS. Type of gastrectomy, lymphadenectomy, pN status, Rx resection, and RIOT group were associated with OS. CONCLUSION Older age, high NLR, and major POC were risk factors for inability to RIOT. RIOT was an independent predictor of survival.

Abstract
INTRODUCTION Although the first laparoscopic gastrectomy was performed in 1991, there was a long delay until it was incorporated into the regular practice of western surgeons. In Brazil, there are only few case series reported and data on its safety and efficacy along with mid- and long-term results are desired. OBJECTIVE Present the mid-term results of laparoscopic gastrectomy with curative intent in the treatment of gastric adenocarcinoma and review the current evidence on the therapy of this neoplasia with the laparoscopic access. METHODS Patients who underwent D2 laparoscopic gastrectomy for gastric adenocarcinoma were retrospectively reviewed. RESULTS Sixty-nine patients met the inclusion criteria. The mean age was 59.2 years and the mean body mass index was 24.2 kg/m2. Subtotal gastrectomy was performed in 73.9%. The mean number of harvested lymph nodes was 36.7, increased lymph node count and shorter operative time were observed in the last 34 cases. Median hospital stay was 8 days. Postoperative complications occurred in 22 (31.9%) cases. Surgical mortality was 4.3%. CONCLUSION Laparoscopic gastrectomy can be performed safely with excellent short- and mid-term results. As experience increases, surgical duration is reduced and lymph node count rises.

Abstract
BACKGROUND Gastric cancer (GC) patients with advanced age and/or multiple morbidities have limited expected survival and may not benefit from extended lymph node resection. The aim of this study was to evaluate the surgical outcomes of these GC patients who underwent gastrectomy with D1 dissection. METHODS We retrospectively reviewed all GC patients who underwent gastrectomy with curative intent from 2009 to 2017. The decision to perform D1 was based on preoperative multidisciplinary meeting, and/or intraoperative clinical judgment. RESULTS Among 460 enrolled patients, 73 (15.9%) underwent D1 lymphadenectomy and 387 (84.1%) D2 lymphadenectomy. Male gender, older age, American Society of Anesthesiologists score (ASA) III/IV, higher neutrophil-to-lymphocyte ratio (NLR) and higher Charlson Comorbidity Index (CCI) were more common in the D1 group. Postoperative major complications were significantly higher in D1 group (24.7% vs 12.4%, p < 0.001) and mostly related to clinical complications. Locoregional recurrence was higher in the D1 group (53.8% vs 39.5%, p = 0.330) however, without statistical significance. No difference was found in disease-free survival (DFS) between D1 and D2 patients with positive lymph nodes (p = 0.192), whereas overall survival was longer in the D2 group (p < 0.001). Multivariate analysis showed a statistically significant impact on survival of age ≥70 years, CCI ≥5, total gastrectomy, D1 lymphadenectomy and advanced stages (III/IV). CONCLUSIONS Frail patients had high surgical mortality even when submitted to D1 dissection. DFS was comparable to D2. Extent of lymphadenectomy in high-risk patients should take in account the expectation of a decrease in surgical risk with the possibility of impairment of long-term survival.

Abstract
OBJECTIVE to evaluate the clinical and pathological characteristics and survival of young patients with gastric cancer, regardless of the intention of treatment. METHODS we conducted a retrospective analysis of all gastric cancer patients undergoing any surgical treatment between 2008 and 2017. We considered patients under 45 years old as young adults and those over 45 years old, as of advanced age. RESULTS of the 875 patients evaluated, 84 (9.6%) were young adults and 791 (90.4%) were older. Younger patients were associated with female gender (p<0.001), lower Charlson score (p=0.002), ASA I/II (p<0.001), diffuse Lauren type (p<0.001) and poorly differentiated tumors (p<0.001). There was no difference between groups regarding treatment intention (palliative versus curative) (p=0.267) and cTNM clinical stage (p=0.120). Disease-free survival was worse in younger individuals (p=0.049), but overall survival was similar between groups (p=0.578). Multivariate analysis identified total gastrectomy, pT3/T4, pN+, and diffuse Lauren type as prognostic factors associated with worse disease-free survival and overall survival. Age was not an independent factor associated with worse prognosis. CONCLUSION although younger patients had lower disease-free survival, overall survival was similar between groups, and age was not a significant independent prognostic factor.

Abstract
OBJECTIVES Surgery remains the cornerstone treatment modality for gastric cancer, the fifth most common type of tumor in Brazil. The aim of this study was to analyze the surgical treatment outcomes of patients with gastric cancer who were referred to a high-volume university hospital. METHODS We reviewed all consecutive patients who underwent any surgical procedure due to gastric cancer from a prospectively collected database. Clinicopathological characteristics, surgical and survival outcomes were evaluated, with emphasis on patients treated with curative intent. RESULTS From 2008 to 2017, 934 patients with gastric tumors underwent surgical procedures in our center. Gastric adenocarcinoma accounted for the majority of cases. Of the 875 patients with gastric adenocarcinoma, resection with curative intent was performed in 63.5%, and palliative treatment was performed in 22.4%. The postoperative surgical mortality rate for resected cases was 5.3% and was related to D1 lymphadenectomy and the presence of comorbidities. Analysis of patients treated with curative intent showed that resection extent, pT category, pN category and final pTNM stage were related to disease-free survival (DFS) and overall survival (OS). The DFS rates for D1 and D2 lymphadenectomy were similar, but D2 lymphadenectomy significantly improved the OS rate. Additionally, clinical factors and the presence of comorbidities had influence on the OS. CONCLUSIONS TNM stage and the type of lymphadenectomy were independent factors related to prognosis. Early diagnosis should be sought to offer the optimal surgical approach in patients with less-advanced disease.

Abstract
BACKGROUND Despite all advances regarding the surgical treatment of gastric cancer (GC), duodenal stump fistula (DF) continues to negatively affect postoperative outcomes. This study aimed to assess DF regarding its incidence, risk factors, management and impact on overall survival. METHODS We retrospectively analyzed 562 consecutive patients who underwent gastrectomy for GC between 2009 and 2017. Clinicopathological characteristics analysis was performed comparing DF, other surgical fistulas and patients with uneventful postoperative course. RESULTS DF occurred in 15 (2.7%) cases, and 51 (9%) patients had other surgical fistulas. Tumor located in the lower third of the stomach (p = 0.021) and subtotal gastrectomy (p = 0.002) were associated with occurrence of DF. The overall mortality rate was 40% for DF and 15.7% for others surgical fistulas (p = 0.043). The median time of DF onset was on postoperative day 9 (range 1-75). Conservative approach was performed in 8 patients and surgical intervention in 7 cases. Age (OR 7.41, p = 0.012) and DF (OR 9.06, p=0.020) were found to be independent risk factors for surgical mortality. Furthermore, patients without fistula had better long-term survival outcomes comparing to patients with any type of fistulas (p = 0.006). CONCLUSION DF is related with distal tumors and patients submitted to subtotal gastrectomy. It affects not only the postoperative period with high morbidity and mortality rates, but may also have a negative impact on long-term survival.

Abstract
BACKGROUND AND OBJECTIVES The role of inflammation in cancer development is a well-known phenomenon that may be represented by the neutrophil-lymphocyte ratio (NLR). The present research intends to determine the impact of NLR on the survival outcome of patients with gastric cancer (GC), and to evaluate its use as a stratification factor for the staging groups. METHODS Data regarding clinical characteristics, surgery, pathology, and follow-up were retrospectively collected from our single-center prospective database. Blood samples were obtained before surgery. RESULTS A total of 383 patients (231 males) who underwent gastrectomy with lymphadenectomy were evaluated between 2009 and 2016. NLR established cutoff was 2.44, and patients were divided in NLR ≥2.44 (hNLR) and <2.44 (lNLR). hNLR patients (38.4% of the cases) had lower disease-free survival and overall survival (OS) compared to lNLR patients (P = 0.047 and P = 0.045, respectively). Risk stratification according to NLR value was done in same tumor depth (T4 and <T4), stage (III and <III) and lymph node status (N+ and N-) group of patients. The OS was significantly lower when NLR was high in same tumor depth (P = 0.032) and stage (P = 0.020), but not in same lymph node status patients (P = 0.184). In a multivariate analysis, NLR was an independent factor of worse OS (HR 1.50 95%CI 1.27-4.21, P = 0.048). CONCLUSION A high NLR was an independent risk factor for reduced survival in GC patients submitted to potentially curative resection. Calculating NLR is easily reproducible and may be incorporated in pre-operative evaluation.

Abstract
Objective Adjuvant chemotherapy with 5-fluorouracil (5-FU) has been widely used in gastric cancer (GC) patients to prevent relapse after curative resection. 5-FU acts by inhibiting thymidylate synthase (TS), and high levels of TS correlate with resistance to treatment with fluoropyrimidines. The aim of this study was to evaluate the expression of TS in GC patients, and its relation with clinicopathological characteristics and prognosis in adjuvant chemotherapy with 5-FU. Methods We retrospectively evaluated 285 patients who underwent D2-gastrectomy with curative intent. TS expression was determined by immunohistochemistry (IHC) in tumor cells by tissue microarray (TMA). TS level was evaluated according to the intensity and percentage of cells marked by a score system. Patients were divided in three groups according to their TS-score: negative, low and high. Results TS expression was positive in 92.3% of GC. TS-high, TS-low and TS-negative were observed in 46.3%, 46.0% and 7.7% of patients, respectively. High-TS GC were associated with older age (P=0.007), high neutrophil/lymphocyte ratio (P=0.048), well/moderately differentiated histology (P=0.001), intestinal Lauren type (P<0.001) and absence of perineural invasion (P=0.003). Among 285 patients, 133 stage II/III patients (46.7%) received chemotherapy with 5-FU. In survival analysis, TS-high was associated with worse disease-free survival (DFS) in stage III GC patients who received 5-FU-based chemotherapy (P=0.007). Multivariate analysis revealed that total gastrectomy, poorly differentiated tumors and high TS-score were associated with worse DFS in stage III GC patients. Conclusions High TS-score in stage III GC was associated with poor DFS in patients treated with fluoropyrimidine-based chemotherapy.

Abstract
High levels of inflammatory markers and the neutrophil-lymphocyte ratio appear to be associated with worse overall survival in solid tumors. However, few studies have analyzed the role of the neutrophil-lymphocyte ratio in gastric cancer patients scheduled to undergo curative resection. In the present study, a systematic review and meta-analysis was performed to analyze the relationship between the neutrophil-lymphocyte ratio and overall survival in patients with gastric cancer submitted to curative resection and to identify the clinicopathological features (age, gender, tumor depth, nodal involvement and tumor differentiation) that are correlated with high neutrophil-lymphocyte ratios. A literature search of PubMed, Scopus, Cochrane and EMBASE through November 2017 was conducted. Articles that included gastric cancer patients submitted to curative resection and preoperatory neutrophil-lymphocyte ratio values were included. A total of 7 studies comprising 3264 patients from 5 different countries were included. The meta-analysis revealed an association of high neutrophil-lymphocyte ratios with older age, male gender, lower 5-year overall survival, increased depth of tumor invasion, positive nodal involvement but not with histological differentiation. Evaluation of the neutrophil-lymphocyte ratio is a cost-effective method that is widely available in preoperatory settings. Furthermore, it can effectively predict prognosis, as high values of this biomarker are related to more aggressive tumor characteristics. This ratio can also be used to stratify risk in patients within the same disease stage and may be used to assist in individualized follow-up and treatment.

Abstract
INTRODUCTION The frequency of gastric neuroendocrine tumors is increasing. Reasons are the popularization of endoscopy and its technical refinements. Despite this, they are still poorly understood and have complex management. AIM Update the knowledge on gastric neuroendocrine tumor and expose the future perspectives on the diagnosis and treatment of this disease. METHOD Literature review using the following databases: Medline/PubMed, Cochrane Library and SciELO. Search terms were: gastric carcinoid, gastric neuroendocrine tumor, treatment. From the selected articles, 38 were included in this review. RESULTS Gastric neuroendocrine tumors are classified in four clinical types. Correct identification of the clinical type and histological grade is fundamental, since treatment varies accordingly and defines survival. CONCLUSION Gastric neuroendocrine tumors comprise different subtypes with distinct management and prognosis. Correct identification allows for a tailored therapy. Further studies will clarify the diseases biology and improve its treatment.

Abstract
BACKGROUND Lymphoepithelioma-like gastric carcinoma (LLGC) is a rare subtype of gastric carcinoma (GC) characterized by prominent lymphocytic infiltration. LLGC may be associated with latent Epstein-Barr virus (EBV) infection or microsatellite instability (MSI). This study aims to assess the clinicopathological characteristics, EBV infection, and MSI status in LLGC. METHODS A retrospective analysis of GC patients submitted to potentially curative resection between 2009 and 2014 was performed. The LLGC subtype specimens were examined for EBV by in situ hybridization and MSI by immunohistochemical analysis. The LLGC profile was analyzed accordingly to clinicopathological parameters. RESULTS From 255 patients, seven were identified on the pathological report as LLGC. Six cases were EBV-positive and one had MSI, showing loss of MLH1 and PMS2 expression. LLGC was more frequently seen in men, and the mean age was 69 years. When compared to non-LLGC, LLGC cases were larger (∼5.8 cm) poorly differentiated tumors and had lower incidence of lymph node metastasis (P = 0.045). Mean number of lymph nodes dissected in the LLGC group was 39.5, and only one patient had a single positive lymph node. In addition, two patients presented associated lesions. LLGC was not associated with HER-2, chromogranin and synaptophysin positivity or Helicobacter pylori infection. CONCLUSIONS Distinct pathological aspects and clinical behavior of LLGC reinforce the need for proper recognition of this histological subtype to choose better therapeutic approaches.

Abstract
BACKGROUND The presence of lymph nodes metastasis is one of the most important prognostic indicators in gastric cancer. The micrometastases have been studied as prognostic factor in gastric cancer, which are related to decrease overall survival and increased risk of recurrence. However, their identification is limited by conventional methodology, since they can be overlooked after routine staining. AIM To investigate the presence of occult tumor cells using cytokeratin (CK) AE1/AE3 immunostaining in gastric cancer patients histologically lymph node negative (pN0) by H&E. METHODS Forty patients (T1-T4N0) submitted to a potentially curative gastrectomy with D2 lymphadenectomy were evaluated. The results for metastases, micrometastases and isolated tumor cells were also associated to clinicopathological characteristics and their impact on stage grouping. Tumor deposits within lymph nodes were defined according to the tumor-node-metastases guidelines (7th TNM). RESULTS A total of 1439 lymph nodes were obtained (~36 per patient). Tumor cells were detected by immunohistochemistry in 24 lymph nodes from 12 patients (30%). Neoplasic cells were detected as a single or cluster tumor cells. Tumor (p=0.002), venous (p=0.016), lymphatic (p=0.006) and perineural invasions (p=0.04), as well as peritumoral lymphocytic response (p=0.012) were correlated to CK-positive immunostaining tumor cells in originally negative lymph nodes by H&E. The histologic stage of two patients was upstaged from stage IB to stage IIA. Four of the 28 CK-negative patients (14.3%) and three among 12 CK-positive patients (25%) had disease recurrence (p=0.65). CONCLUSION The CK-immunostaining is an effective method for detecting occult tumor cells in lymph nodes and may be recommended to precisely determine tumor stage. It may be useful as supplement to H&E routine to provide better pathological staging.

Abstract
Intraperitoneal free cancer cells in gastric adenocarcinoma are associated with a poor outcome. However, the true prognostic value of intraperitoneal free cancer cells is still unclear, leading to a lack of consensus in the management of gastric cancer. The aim of the present study is to perform a systematic review and meta-analysis to analyze intraperitoneal free cancer cells-positive patients with regard to tumor oncologic stage, recurrence, grade of cellular differentiation, and survival rates and to analyze the clinical significance of intraperitoneal free cancer cells with regard to prognosis. Databases were searched up to January 2016 for prognostic factors associated with intraperitoneal free cancer cells, including oncologic stage, depth of neoplasm invasion, lymph nodal spread, differentiation grade of the tumor, and recurrence and survival rates. A total of 100 studies were identified. Meta-analysis revealed a clear association between intraperitoneal free cancer cells and a poor prognosis. intraperitoneal free cancer cells -positive patients had higher rates of nodal spread (risk difference: 0.29; p<0.01), serosal invasion (risk difference: 0.43; p<0.01), recurrence (after 60 months of follow-up, risk difference: 0.44; p<0.01), and mortality (after 60 months of follow-up, risk difference: 0.34; p<0.01). Intraperitoneal free cancer cells are associated with a poor outcome in gastric cancer. This surrogate biomarker should be used to guide therapy both prior to and after surgery.

Abstract
BACKGROUND Pathological examination of a minimum of 16 lymph nodes is recommended following surgery for gastric adenocarcinoma, despite this a longer survival is expected when 30 or more lymph nodes are examined. Small lymph nodes are difficult to identify, and fat-clearing solutions have been proposed to improve this, but there is no evidence of their clinical benefit. METHODS Fifty D2 subtotal gastrectomy specimens were randomized for fixation in Carnoy's solution (CS) or 10% neutral buffered formalin (NBF), with subsequent fat dissection. After dissection, the residual fat from the NBF group, instead of being discarded, was immersed in CS and dissected again. Data from 25 D2 subtotal gastrectomies performed before the study were also analyzed. RESULTS The mean number of examined lymph nodes was 50.4 and 34.8 for CS and NBF, respectively (p < 0.001). Missing lymph nodes were found in all cases from the residual fat group (mean of 16.9), and in eight of them (32%) metastatic lymph nodes were present; this allowed the upstaging of two patients. Lymph nodes in the CS group were smaller than those in the NBF group (p = 0.01). The number of retrieved lymph nodes was similar among the NBF and Retrospective groups (p = 0.802). CONCLUSIONS Compared with NBF, CS increases lymph node detection following gastrectomy and allows a more accurate pathological staging. No influence of the research protocol on the number of examined lymph nodes was observed.

Abstract
Intraoperative injury of the obturator nerve is not an infrequent complication of gynecological surgeries. This injury can occur in association with pelvic lymphadenectomy for uterine or cervical cancer. This manuscript demonstrates an alternative technique for the obturator nerve repair, when primary end to end anastomosis is not possible.

Abstract
AIM Chagas' disease is an endemic parasitosis found in Latin America. The disease affects different organs, such as heart, oesophagus, colon and rectum. Megacolon is the most frequent long-term complication, caused by damage to the myoenteric and submucous plexus, ultimately leading to a functional barrier to the faeces. Patients with severe constipation are managed surgically. The study aimed to analyse the 10-year minimum functional outcome after rectosigmoidectomy with posterior end-to-side anastomosis (RPESA). METHOD A total of 21 of 46 patients were available for follow up. Patients underwent clinical, radiological and manometric evaluation, and the results were compared with preoperative parameters. RESULTS Of the 21 patients evaluated, 81% (17) were female, with a mean age of 60.6 years. Good function was achieved in all patients, with significant improvement in defaecatory frequency (P < 0.0001), usage of enemas (P < 0.0001) and patient satisfaction. Barium enema also showed resolution of the colonic and rectal dilatation in 19 cases evaluated postoperatively. CONCLUSION Minimal 10-year follow up of RPESA showed excellent functional results, with no recurrence of constipation.

Abstract
A doença de Crohn é uma moléstia com um amplo espectro de manifestações. Seu tratamento é complexo e freqüentemente os pacientes portadores desta afecção necessitam de intervenções cirúrgicas. Com o surgimento da laparoscopia e sua popularização no tratamento das afecções intestinais, demonstrando resultados superiores ao acesso convencional e quebrando paradigmas como sua utilização no tratamento do câncer colorretal, passou-se a cogitar se esse acesso seria indicado também nas doenças inflamatórias intestinais. Ainda hoje, a utilização desta via de acesso na doença de Crohn é tema controverso. Devido à natureza inflamatória desta patologia, o grau de dificuldade cirúrgico está aumentado e muitas dúvidas persistem: há benefício para o paciente? A taxa de conversão não está exageradamente aumentada? É possível indicar esse acesso em casos complicados? Qual o grupo de pacientes que se beneficia da técnica? Nesta revisão apresentamos os dados mais recentes e as evidências científicas que sustentam a indicação da via de acesso laparoscópica no tratamento cirúrgico da doença de Crohn.

Abstract
"Collision tumors" consist of two independent but coexisting tumors. This uncommon situation might be easily mistaken for a composite tumor where one histogenetic event originates from two apparently distinct neoplasms. Colorectal collisions are particularly unusual; here, we report the exceedingly rare case of a 61-year-old man with malignant melanoma and adenocarcinoma colliding in the rectum. Collision tumors have an idiopathic pathophysiology and in fact "accidental meeting" is accepted by many authors. This article discusses the concepts about cancer development, which are overlooked by this hypothesis, another theory to explain that this rare occurrence involves microenvironment changes.

Abstract
OBJECTIVES To compare the effect of conjugated equine estrogens (CEE) and raloxifene on lipid profile and hemostasis. MATERIALS AND METHODS A double-blind, randomized and parallel study was performed with 90 healthy postmenopausal women, aged 54 +/- 5 years, divided into three groups and submitted to daily therapy with either CEE 0.625 mg, raloxifene 60 mg or placebo for 4 months. The lipid profile, coagulation and fibrinolytic factors were analyzed. RESULTS CEE increased the levels of high density lipoprotein cholesterol (HDL-C) from 49.0 to 56.8 mg/dl (p < 0.001), very low density lipoprotein cholesterol (VLDL-C) from 17.2 to 22.3 mg/dl (p < 0.001), and triglycerides from 86.0 to 111.7 mg/dl (p < 0.001), and decreased the levels of low density lipoprotein cholesterol (LDL-C) from 121.0 to 106.5 mg/dl (p < 0.001). The only significant effect of raloxifene was an increase in the levels of HDL-C from 46.0 to 47.8 mg/dl (p = 0.019). There was no significant reduction in LDL-C, from 115.5 to 110.2 mg/dl (p = 0.06), VLDL-C, from 21.7 to 20.0 mg/dl (p = 0.201), and triglycerides, from 108 to 100 mg/dl (p = 0.201). CEE decreased the levels of fibrinogen, from 370.5 to 326.8 g/l (p = 0.039) and the levels of antithrombin III, from 99.5 to 93.2% (p < 0.001). Raloxifene decreased the levels of fibrinogen, from 354.7 to 302.0 g/l (p = 0.009) and the levels of antithrombin III, from 102.4 to 98.5% (p = 0.039). CEE increased levels of protein C from 103.7 to 115.3 mg/l (p < 0.001) and raloxifene did not change the levels of protein C (107.9 to 105.1 mg/l; p = 0.158). CEE decreased the antigen levels of tissue plasminogen activator (t-PA) from 8.8 to 6.8 U/ml (p < 0.001), and of plasminogen activator inhibitor (PAI-1) from 30.8 to 21.6 U/ml (p < 0.010), whereas raloxifene had no significant effect on either t-PA, from 9.6 to 9.2 U/ml (p = 0.235) or PAI-1 antigen levels, from 32.1 to 30.4 U/ml (p = 0.538). CONCLUSION Both CEE and raloxifene exert significant effects on the lipid and coagulation profile. CEE had a more significant effect on fibrinolysis than raloxifene. These effects may have a significant impact on the cardiovascular risk that needs to be confirmed in larger studies.
